The OneDrive class makes it easy to upload, download, and manage files and folders within Microsoft OneDrive.

Syntax

OneDrive

Remarks

The OneDrive class provides a simple interface to working with Microsoft OneDrive. Capabilities include uploading and downloading files, strong encryption support, creating folders, moving and copying resources, OneDrive for Business and SharePoint Online support, and more.

To begin, first create an account and register your application with the Microsoft Graph API. Consult the Microsoft Graph API documentation for instructions on this process.

Authentication

This class requires authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth property to set the appropriate fields for the chosen ClientProfile and GrantType.

The class has the following default ServerAuthURL and ServerTokenURL fields. Additionally, below is a common scope for the class:

Additionally, depending on how the application is registered (Ex. Multi-tenant) and what GrantType is selected (Ex. Client Credentials and Password), it may be required to use the tenant ID rather than "common" in the ServerAuthURL and ServerTokenURL fields. In the case of Client Credentials and Password grant types, it is also required to use the "default" scopes of the app registration. See below for examples of the modified URLs and scopes:

Below is a brief description of the different ClientProfile and GrantType values that are supported by this class. For a more in-depth description of what needs to be set, refer to the service documentation.

Application Profile

This profile encompasses the most basic grant types that OAuth supports. When this profile is set, all the requests and response handling is done by the class. Depending on the grant type, this may involve launching a browser so a user can login to authenticate with a authorization server. It may also involve starting an embedded web server to receive a response from a redirect.

To start the authentication and authorization process, the Authorize method should be called. If the authorization and authentication was successful, then the AccessToken field will be populated. Additionally, if a refresh token was provided the RefreshToken field will be populated as well. These values of the fields are for informational purposes. The class will also cache these tokens along with when the AccessToken will be expired. When a method that makes requests to the service provider is called or the Authorize method is called the class will automatically check to see if the access token is expired. If it is, it will then automatically try to get a new AccessToken. If the Authorize method was not used and user interaction would be required, the class will throw an error which can be caught. When user interaction is needed depends on what grant type is set in the GrantType field. To force the component to only check the access token when the Authorize method is called, the OAuthAutomaticRefresh configuration setting can be set to false.

A brief description of the supported values for the GrantType field are below. For more information, see the service documentation.

Authorization Code

When using the Authorization Code grant type, the class will use an authorization code to get an access token. For this GrantType the class expects a ClientId, ClientSecret, ServerAuthURL, and ServerTokenURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the authorization code, setting the AuthorizationCode field, from the redirect. Immediately, the class will make a request to the token server to exchange the authorization code for an access token. The token server will return an access token and possibly a refresh token. If the RefreshToken field is set, or a refresh token is cached, then the class will not launch the browser and use the refresh token in its request to the token server instead of an authorization code.

Example: Onedrive onedrive = new Onedrive(); onedrive.OAuth.ClientProfile = CloudOAuthClientProfiles.cocpApplication; onedrive.OAuth.GrantType = OAuthSettingsGrantTypes.cogtAuthorizationCode; onedrive.OAuth.ClientId = CLIENT_ID; onedrive.OAuth.ClientSecret = CLIENT_SECRET; onedrive.OAuth.AuthorizationScope = "offline_access files.readwrite files.readwrite.all"; onedrive.Authorize();

Client Credentials

When using the Client Credentials grant type, the class will act as a service instead of authorizing and authenticating as a user. This allows for the class to avoid user interaction. This is typically used when running in an application that can not have user access. This grant type requires additional set up to be done in the service providers portal before it can be used. For this GrantType the class expects a ClientId, ClientSecret, and ServerTokenURL to be set. When the Authorize method is called, the component will make a request to the token server for an access token. The token server will return an access token if the application has the authorization to do so. When this access token is expired, the component will automatically (see above for detailed description) make a new request to get a fresh one.

Implicit

Note: This grant type is considered insecure and should only be used when necessary.

When using the Implicit grant type, the class will request the authorization server to get an access token. For this GrantType the class expects a ClientId, ClientSecret, and ServerAuthURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the class will parse the access token from the redirect.

A disadvantage of the grant type is that can not use a refresh token to silently get a new access token. Most service providers offer a way to silently get a new access token. See the service documentation for specifics. This means the class will not be able to automatically get a fresh token once it expires.

Password

Note: This grant type is considered insecure and should only be used when necessary.

When using the Resource Owner Password Credentials grant type, the class will authenticate as the resource owner. This allows for the class to avoid user interaction. This grant type often has specific limitations put on it by the service provider. See the service documentation for more details.

For this GrantType the class requires OAuthPasswordGrantUsername, ClientSecret, and ServerTokenURL to be set. The ClientSecret should be set to the password of the account instead of a typical secret. In some cases, the ClientId also needs to be set. When the Authorize method is called, the component will make a request to the token server for an access token using the username and password. The token server will return an access token if the authentication was successful. When this access token is expired, the component will automatically (see above for detailed description) make a new request to get a fresh one.

Web Profile

External OAuth Support

Bearer ACCESS_TOKEN_VALUE

Assign this value to the Authorization property before attempting any operations. Setting the Authorization property will cause the class to ignore the values set in the OAuth property.

For Example: Oauth oauth = new Oauth(); oauth.ClientId = "CLIENT_ID"; oauth.ClientSecret = "CLIENT_SECRET; oauth.ServerAuthURL = "https://login.microsoftonline.com/common/oauth2/v2.0/authorize"; oauth.ServerTokenURL = "https://login.microsoftonline.com/common/oauth2/v2.0/token"; oauth.AuthorizationScope = "offline_access files.readwrite files.readwrite.all"; oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode; onedrive.Authorization = oauth.GetAuthorization(); Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

Note: There are a couple of extra factors to consider when doing OAuth for OneDrive; please refer to the Authorization property documentation for more information.

Listing Resources

ListResources lists resources within the folder resource currently selected by RemoteId or RemotePath. Calling this method will fire the ResourceList event once for each resource, and will also populate the Resources properties.

If there are still more resources available to list when this method returns, the ResourceMarker property will be populated. Continue to call this method until ResourceMarker is empty to accumulate all pages of results in the Resources properties. Alternatively, the AccumulatePages configuration setting can be disabled to clear the Resources properties every time a page of results is returned. // ResourceList event handler. onedrive.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; // (Assume that the RemoteId property isn't set; it takes precedence if it is.) onedrive.RemotePath = "/work_files/serious_business/cats"; do { onedrive.ListResources(); for (int i = 0; i < onedrive.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(onedrive.ResourceMarker));

Downloading Files

The DownloadFile method downloads the file resource currently selected by RemoteId or RemotePath.

If a stream has been specified using SetDownloadStream, the file data will be sent through it. If a stream is not specified, and LocalFile is set, the file will be saved to the specified location; otherwise, the file data will be held by ResourceData.

To download and decrypt an encrypted file, set EncryptionAlgorithm and EncryptionPassword before calling this method.

Download Notes

In the simplest use-case, downloading a file looks like this: onedrive.LocalFile = "../MyFile.zip"; onedrive.RemoteId = onedrive.Resources[0].Id; onedrive.DownloadFile();

Resuming Downloads

The class also supports resuming failed downloads by using the StartByte property. If a download is interrupted, set StartByte to the appropriate offset before calling this method to resume the download. string downloadFile = "../MyFile.zip"; onedrive.LocalFile = downloadFile; onedrive.RemoteId = onedrive.Resources[0].Id; onedrive.DownloadFile(); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially downloaded file onedrive.StartByte = new FileInfo(downloadFile).Length; onedrive.DownloadFile();

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when LocalFile was set in the initial download attempt.

If LocalFile is set when beginning an encrypted download, the class creates a temporary file in TempPath to hold the encrypted data until the download is complete. If the download is interrupted, DownloadTempFile will be populated with the path of the temporary file that holds the partial data.

To resume, DownloadTempFile must be populated, along with StartByte, to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to LocalFile. onedrive.LocalFile = "../MyFile.zip"; onedrive.EncryptionPassword = "password"; onedrive.RemoteId = onedrive.Resources[0].Id; onedrive.DownloadFile(); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially download temp file onedrive.StartByte = new FileInfo(onedrive.Config("DownloadTempFile")).Length; onedrive.DownloadFile();

Uploading Files

The UploadFile method uploads new file resources to the folder resource currently selected by RemoteId or RemotePath.

If SetUploadStream has been used to set an upload stream, it will take priority as the file data source. If LocalFile is set the file will be uploaded from the specified path. If LocalFile is not set the data in ResourceData will be used.

To encrypt the file before uploading it, set EncryptionAlgorithm and EncryptionPassword.

Upload Notes

OneDrive offers two ways to upload a file. For smaller files a simple upload option is provided to upload data in one request. This is the default option. For larger files, uploads can be fragmented into multiple pieces, allowing resuming of uploads that may be interrupted.

Simple

By default the class uses the simple upload mechanism. onedrive.LocalFile = "../MyFile.zip"; onedrive.UploadFile("MyFile.zip");

Resumable

To enable resumable uploads set UseResumableUpload to true. This is recommended for large files. The class will automatically fragment the specified file into smaller pieces and upload each individually. FragmentSize may be set to specify the size of the fragment if desired. The default fragment size is 10 MB.

When UseResumableUpload is set to true and UploadFile is called, a resumable upload session is started by the class. ResumeURL is populated with a URL identifying the session (this value may be needed for additional operations if the upload does not complete normally).

During a resumable upload, the FragmentComplete event fires after each fragment is uploaded to indicate overall progress. The class also updates StartByte as necessary to indicate the current offset in the file.

If the upload is interrupted for any reason, resuming it is easy. First, verify that ResumeURL and StartByte are populated (if the same instance of the class is used, they should already be populated, and no special action should be needed). If uploading from a stream, be sure to reset its position to where it was the first time the upload was started (typically the beginning). Then call UploadFile again to resume the upload at the specified StartByte offset.

Note that if the upload is not resumed after some time the upload session will expire. PollUploadStatus may be used to check the status of a resumable upload, including when it will expire (which is stored in the UploadExpDate configuration setting). An interrupted upload can be aborted explicitly using the AbortUpload method. onedrive.LocalFile = "../MyFile.zip"; onedrive.UploadFile("MyFile.zip"); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte and ResumeURL are already populated from the previous //upload attempt. onedrive.UploadFile("MyFile.zip"); MemoryStream uploadStream = new MemoryStream(File.ReadAllBytes("../MyFile.zip")); onedrive.SetUploadStream(uploadStream); onedrive.UploadFile("MyFile.zip"); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte and ResumeURL are already populated from the previous //upload attempt. //You MUST reset the stream's position to where it was when you first started the upload! uploadStream.Position = 0; onedrive.UploadFile("MyFile.zip");

""

Remarks

This class supports authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth property, using the OAuth class or a separate process. If using the OAuth property, then the Authorization property will not be used. Once complete you should have an authorization string which looks like:

Bearer ACCESS_TOKEN

Authorization Notes

At this time, the most straightforward instructions available for registering an application for use with Microsoft Graph can be found on Register your app page of the Microsoft Graph API documentation. One of the steps on that page is selecting the application's supported account types. In most cases, the "Accounts in any organizational directory and personal Microsoft accounts" option is the most appropriate.

Once the application is registered, refer to the instructions on the Get access on behalf of a user page of the Microsoft Graph API documentation for information about what endpoints to use with the OAuth class for authentication. Pay special attention to the description of the possible value for the {tenent} segment of the OAuth endpoints.

The relevant OAuth scopes vary based on whether the application will use OneDrive (Personal), or OneDrive for Business and/or SharePoint Online.

• OneDrive (Personal): The Files.* scopes.
• OneDrive for Business / SharePoint Online: The Files.* and Sites.* scopes (to use the UsersGroups configuration setting, the Group.Read.All and/or Directory.Read.All scopes are also relevant).

Refer to the Microsoft Graph API's permissions documentation for more information about the OAuth scopes that Microsoft Graph supports.

QString GetDrive();
int SetDrive(QString qsDrive);

Default Value

""

Remarks

This property can be set to the Id of a specific drive to select it for use.

When this property is empty (default), the class uses the following logic to determine which drive to select:

1. If the GroupId and SiteId configuration settings are both empty (also default), the current user's default drive is used.
2. Otherwise, if the GroupId configuration setting is populated, that group's default drive is used.
3. Otherwise, if the SiteId configuration setting is populated, that site's default drive is used.

Note: For use-cases that only make use of the current user's default drive (e.g., when authenticated with a personal Microsoft account), there is no need to ever call ListDrives, set the Drive property, or use any of the class's other drive-related API members. By default, the Drive property and the GroupId and SiteId configuration settings are all empty, which causes the class to use the current user's default drive.

This property is not available at design time.

Default Value

""

Remarks

If this property is populated when UploadFile or DownloadFile is called, the class will attempt to encrypt or decrypt the data before uploading or after downloading it.

The class uses the value specified here to generate the necessary encryption Key and IV values using the PKCS5 password digest algorithm. This provides a simpler alternative to creating and managing Key and IV values directly.

However, it is also possible to explicitly specify the Key and IV values to use by setting the EncryptionKey and EncryptionIV configuration settings. This may be necessary if, e.g., the data needs to be encrypted/decrypted by another utility which generates Key and IV values differently.

This property is not available at design time.

int cloudstorage_onedrive_setlocalfile(void* lpObj, const wchar_t* lpszLocalFile); // Windows only

QString GetLocalFile();
int SetLocalFile(QString qsLocalFile);

Default Value

""

Remarks

This property specifies the location of a file on disk. This is used as the source file when calling UploadFile or UpdateResource, and as the destination file when calling DownloadFile.

Note: Setting this property to a non-empty value will discard any streams set using SetDownloadStream and SetUploadStream. Similarly, passing a non-null value to either of the aforementioned methods will clear this property.

Data Type

String

LocalHost Property (OneDrive Class)

The name of the local host or user-assigned IP interface through which connections are initiated or accepted.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetLocalHost();
int SetLocalHost(const char* lpszLocalHost);

Unicode (Windows)
LPWSTR GetLocalHost();
INT SetLocalHost(LPCWSTR lpszLocalHost);

char* cloudstorage_onedrive_getlocalhost(void* lpObj);
int cloudstorage_onedrive_setlocalhost(void* lpObj, const char* lpszLocalHost);

QString GetLocalHost();
int SetLocalHost(QString qsLocalHost);

Default Value

""

Remarks

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the class is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: LocalHost is not persistent. You must always set it in code, and never in the property window.

Data Type

Range Property (OneDrive Class)

The range of bytes to request.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* GetRange();
int SetRange(const char* lpszRange);

Unicode (Windows)
LPWSTR GetRange();
INT SetRange(LPCWSTR lpszRange);

char* cloudstorage_onedrive_getrange(void* lpObj);
int cloudstorage_onedrive_setrange(void* lpObj, const char* lpszRange);

QString GetRange();
int SetRange(QString qsRange);

Default Value

""

Remarks

This property specifies the range of bytes to request from the server. If this property is non-empty when a DownloadFile request is being constructed, a header like Range: bytes=Range will be added to the request, with Range substituted with the specified value.

There are two valid formats for this property's value:

• StartByte-
• StartByte-EndByte

Note: If the StartByte property is greater than zero when DownloadFile is called (i.e., when a download is being resumed), and this property is non-empty, the class will automatically advance the StartByte value in the specified range by StartByte bytes when sending the Range header to the server. This ensures that the previously-downloaded data at the start of the specified range is not downloaded again when the download is resumed.

This property is not available at design time.

Data Type

String

RemoteId Property (OneDrive Class)

Selects a remote resource by Id.

Syntax

int cloudstorage_onedrive_setremoteid(void* lpObj, const char* lpszRemoteId);

QString GetRemoteId();
int SetRemoteId(QString qsRemoteId);

Default Value

""

Remarks

This property selects a remote file or folder resource to operate against using its resource Id.

Remote Id and Path Notes

Keep the following things in mind when setting the RemoteId and/or RemotePath properties:

• If both RemoteId and RemotePath are set, RemoteId is used.
• The Id or path provided must always be for a resource that resides in the drive currently selected by Drive.
• Some methods operate against only file or only folder resources; while others can operate against either one. Calling a method while RemoteId/RemotePath is set to the Id/path of a resource whose type is unsupported will cause the server to return an error; use the table below to determine which resource types each method supports.

  Method Name	Files	Folders
  CopyResource	X	X
  CreateFolder	-	X
  CreateLink	X	X
  DeleteResource	X	X
  DownloadFile	X	-
  GetResourceInfo	X	X
  ListResources	-	X
  MoveResource	X	X
  Search	-	X
  UpdateResource	X	X
  UploadFile	-	X

  Key: X = Supported; - = Not supported.

• Methods that support only folder resources can also operate against the root of the currently selected drive, just clear both RemoteId and RemotePath.
• Some methods may have other restrictions, refer to each one for more information.

Note: The rules regarding acceptable resource types still apply if using the RelativePath configuration setting in tandem with this property. That is, ensure that the resource that the relative path resolves to is of an acceptable type.

This property is not available at design time.

Remarks

If it finds any issues with the certificate presented by the server, the class will normally terminate the connection with an error.

You may override this behavior by supplying a value for SSLAcceptServerCert. If the certificate supplied in SSLAcceptServerCert is the same as the certificate presented by the server, then the server certificate is accepted unconditionally, and the connection will continue normally.

Note: This functionality is provided only for cases in which you otherwise know that you are communicating with the right server. If used improperly, this property may create a security breach. Use it at your own risk.

StartByte Property (OneDrive Class)

The byte offset from which to start the upload or download.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int64 GetStartByte();
int SetStartByte(int64 lStartByte);

Unicode (Windows)
LONG64 GetStartByte();
INT SetStartByte(LONG64 lStartByte);

int64 cloudstorage_onedrive_getstartbyte(void* lpObj);
int cloudstorage_onedrive_setstartbyte(void* lpObj, int64 lStartByte);

qint64 GetStartByte();
int SetStartByte(qint64 lStartByte);

Default Value

0

Remarks

This property may be set to resume an upload or download; it specifies the offset in the file (or stream, when uploading) from which to resume. See UploadFile and DownloadFile for details about resuming uploads and downloads.

When uploading from a stream, the class will always seek forward in the stream if the value of StartByte is greater than 0 when UploadFile is called. Keep this in mind when resuming interrupted uploads.

This property is not available at design time.

Data Type

Long64

Timeout Property (OneDrive Class)

The timeout for the class.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetTimeout();
int SetTimeout(int iTimeout);

Unicode (Windows)
INT GetTimeout();
INT SetTimeout(INT iTimeout);

int cloudstorage_onedrive_gettimeout(void* lpObj);
int cloudstorage_onedrive_settimeout(void* lpObj, int iTimeout);

int GetTimeout();
int SetTimeout(int iTimeout);

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the class fails with an error.

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

Data Type

Integer

UseResumableUpload Property (OneDrive Class)

Whether to use resumable uploads.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int GetUseResumableUpload();

int cloudstorage_onedrive_setuseresumableupload(void* lpObj, int bUseResumableUpload);

bool GetUseResumableUpload();
int SetUseResumableUpload(bool bUseResumableUpload);

Default Value

FALSE

Remarks

This property controls whether simple or resumable uploads are used when UploadFile is called. The default value is false (simple uploads are used).

Refer to UploadFile for more information.

This property is not available at design time.

Data Type

Boolean

AbortUpload Method (OneDrive Class)

Aborts the current resumable upload session.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int AbortUpload();

Unicode (Windows)
INT AbortUpload();

int cloudstorage_onedrive_abortupload(void* lpObj);

int AbortUpload();

Remarks

This method aborts the current resumable upload session specified by ResumeURL. It may be called if the current resumable upload has been interrupted and will not be resumed.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

AddQueryParam Method (OneDrive Class)

Adds a query parameter to the QueryParams properties.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int AddQueryParam(const char* lpszName, const char* lpszValue);

Unicode (Windows)
INT AddQueryParam(LPCWSTR lpszName, LPCWSTR lpszValue);

int cloudstorage_onedrive_addqueryparam(void* lpObj, const char* lpszName, const char* lpszValue);

int AddQueryParam(const QString& qsName, const QString& qsValue);

Remarks

This method is used to add a query parameter to the QueryParams properties. Name specifies the name of the parameter, and Value specifies the value of the parameter.

All specified Values will be URL encoded by the class automatically. Consult the service documentation for details on the available parameters.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Authorize Method (OneDrive Class)

Get the authorization string required to access the protected resource.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int Authorize();

Unicode (Windows)
INT Authorize();

int cloudstorage_onedrive_authorize(void* lpObj);

int Authorize();

Remarks

This method is used to get an access token that is required to access the protected resource. The method will act differently based on what is set in the ClientProfile field and the GrantType field. This method is not to be used in conjunction with the Authorization property. It should instead be used when setting the OAuth property.

For more information, see the introduction section.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

CalcAuthorization Method (OneDrive Class)

Calculates the Authorization header based on provided credentials.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int CalcAuthorization();

Unicode (Windows)
INT CalcAuthorization();

int cloudstorage_onedrive_calcauthorization(void* lpObj);

int CalcAuthorization();

Remarks

This method calculates the Authorization value using the values provided in AuthScheme, User and Password.

In most cases this method does not need to be called. The class will automatically calculate any required authorization values when a method is called such as Get or Post.

This method may be useful in cases where the Authorization value needs to be calculated prior to sending a request.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

Config Method (OneDrive Class)

Sets or retrieves a configuration setting.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* Config(const char* lpszConfigurationString);

Unicode (Windows)
LPWSTR Config(LPCWSTR lpszConfigurationString);

char* cloudstorage_onedrive_config(void* lpObj, const char* lpszConfigurationString);

QString Config(const QString& qsConfigurationString);

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CopyResource Method (OneDrive Class)

Copies the currently selected resource.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int CopyResource(const char* lpszParentId, const char* lpszNewName);

Unicode (Windows)
INT CopyResource(LPCWSTR lpszParentId, LPCWSTR lpszNewName);

int cloudstorage_onedrive_copyresource(void* lpObj, const char* lpszParentId, const char* lpszNewName);

int CopyResource(const QString& qsParentId, const QString& qsNewName);

Remarks

This method copies the resource currently selected by RemoteId or RemotePath. The following outcomes are possible depending on which of NewName and ParentId are provided:

ParentId, if provided, must either be the Id of a folder resource that already exists in the drive currently selected by Drive, or root (an alias for the root of the drive).

Monitoring Copy Operations

All copy operations are asynchronous. After calling CopyResource, the CopyStatusURL configuration setting will be populated with a copy operation monitor URL.

The PollCopyStatus method can be used to retrieve the latest status of the copy operation specified by the CopyStatusURL configuration setting. Calling PollCopyStatus will populate the CopyPercentDone, CopyStatus, and (if applicable) CopiedResourceId properties.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

CreateFolder Method (OneDrive Class)

Creates a new folder resource.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* CreateFolder(const char* lpszFolderName);

Unicode (Windows)
LPWSTR CreateFolder(LPCWSTR lpszFolderName);

char* cloudstorage_onedrive_createfolder(void* lpObj, const char* lpszFolderName);

QString CreateFolder(const QString& qsFolderName);

Remarks

This method creates a new folder resource, with the given FolderName, within the folder resource currently selected by RemoteId or RemotePath. The Id of the newly-created folder resource is returned.

If the ClientCreatedTime and/or ClientModifiedTime configuration settings are non-empty when this method is called, the corresponding timestamps will be submitted with the folder creation request.

Name Conflict Resolution

If the RenameIfExists configuration setting is enabled when this method is called, and the desired FolderName is already in use, the server will modify the name of the new folder resource to be unique. Refer to the RenameIfExists configuration setting for more information.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

CreateLink Method (OneDrive Class)

Creates a resource sharing link.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* CreateLink(int bReadOnly);

Unicode (Windows)
LPWSTR CreateLink(BOOL bReadOnly);

char* cloudstorage_onedrive_createlink(void* lpObj, int bReadOnly);

QString CreateLink(bool bReadOnly);

Remarks

This method creates and returns a sharing link for the resource currently selected by RemoteId or RemotePath. The ReadOnly parameter controls whether the link provides view-only or editing access to the resource in question.

For OneDrive for Business and SharePoint Online resources, the CreateLinkScope configuration setting can also be used to control the access scope used to create the link. // Create a read-only shared link for the given file. onedrive.RemotePath = "/work_stuff/serious_business/best_cat_pictures.zip"; string sharingUrl = onedrive.CreateLink(true);

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

DeleteResource Method (OneDrive Class)

Deletes the currently selected resource.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int DeleteResource();

Unicode (Windows)
INT DeleteResource();

int cloudstorage_onedrive_deleteresource(void* lpObj);

int DeleteResource();

Remarks

This method deletes the resource currently selected by RemoteId or RemotePath. When deleting a folder resource, all of its contents are also deleted.

Important: Resources are deleted permanently!

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

DownloadFile Method (OneDrive Class)

Downloads the currently selected file resource.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int DownloadFile();

Unicode (Windows)
INT DownloadFile();

int cloudstorage_onedrive_downloadfile(void* lpObj);

int DownloadFile();

Remarks

This method downloads the file resource currently selected by RemoteId or RemotePath.

If a stream has been specified using SetDownloadStream, the file data will be sent through it. If a stream is not specified, and LocalFile is set, the file will be saved to the specified location; otherwise, the file data will be held by ResourceData.

To download and decrypt an encrypted file, set EncryptionAlgorithm and EncryptionPassword before calling this method.

Download Notes

In the simplest use-case, downloading a file looks like this: onedrive.LocalFile = "../MyFile.zip"; onedrive.RemoteId = onedrive.Resources[0].Id; onedrive.DownloadFile();

Resuming Downloads

The class also supports resuming failed downloads by using the StartByte property. If a download is interrupted, set StartByte to the appropriate offset before calling this method to resume the download. string downloadFile = "../MyFile.zip"; onedrive.LocalFile = downloadFile; onedrive.RemoteId = onedrive.Resources[0].Id; onedrive.DownloadFile(); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially downloaded file onedrive.StartByte = new FileInfo(downloadFile).Length; onedrive.DownloadFile();

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when LocalFile was set in the initial download attempt.

If LocalFile is set when beginning an encrypted download, the class creates a temporary file in TempPath to hold the encrypted data until the download is complete. If the download is interrupted, DownloadTempFile will be populated with the path of the temporary file that holds the partial data.

To resume, DownloadTempFile must be populated, along with StartByte, to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to LocalFile. onedrive.LocalFile = "../MyFile.zip"; onedrive.EncryptionPassword = "password"; onedrive.RemoteId = onedrive.Resources[0].Id; onedrive.DownloadFile(); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially download temp file onedrive.StartByte = new FileInfo(onedrive.Config("DownloadTempFile")).Length; onedrive.DownloadFile();

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

GetCurrentChangeMarker Method (OneDrive Class)

Gets the most current change marker.

Syntax

Calling this method will fire the DriveList event, and will populate the Drives properties with a single item (clearing any previously-held items in the process).

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

GetResourceInfo Method (OneDrive Class)

Gets information about the currently selected resource.

Syntax

• C++
• C

If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

ListChanges Method (OneDrive Class)

Lists changes to resources in the currently selected drive.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int ListChanges();

Unicode (Windows)
INT ListChanges();

int cloudstorage_onedrive_listchanges(void* lpObj);

int ListChanges();

Remarks

This method lists changes to resources in the drive currently selected by Drive.

Starting from a Baseline State

For most use-cases, it is necessary to obtain a baseline of the full drive hierarchy in order to have a context onto which later changes can be applied.

To obtain a full drive hierarchy baseline, ensure that both ChangeMarker and NextChangeMarker are empty, and then call ListChanges. Then follow the process described in the "General Usage" section (below) until ChangeMarker is empty, keeping in mind that the results being returned are not necessarily* changes, but rather the current state of all resources in the drive.

*If any resources in the drive are changed before all result pages of the baseline have been returned, OneDrive may append those change items to the end of the baseline's results. Refer to the "Usage Considerations" section (below) for more information.

Starting from the Latest State

For use-cases that don't require a baseline (e.g., perhaps an application just displays a "ticker" with change information), call GetCurrentChangeMarker. This will populate NextChangeMarker immediately.

General Usage

When this method is called, it will use the change marker stored in either ChangeMarker or NextChangeMarker (only one can be populated at a time) to request the next page of changes. This method causes the ResourceList event to fire once for each change, and will also populate the Resources properties.

If there are still more changes available to list when this method returns, the ChangeMarker property will be populated. Continue to call this method until ChangeMarker is empty to accumulate all pages of results in the Resources properties. (Once there aren't any more changes available to list, the NextChangeMarker property will be populated instead.) Alternatively, the AccumulatePages configuration setting can be disabled to clear the Resources properties every time a page of results is returned.

When NextChangeMarker is populated, it is always populated with a value that (at the time of population) points to the most current state. (Since "the most current state" implies that there are no further changes to list, calling ListChanges immediately after NextChangeMarker is populated will not return any further changes.)

Example of Getting a Baseline and then Listing Changes // Get a full drive hierarchy baseline first. Onedrive onedrive = new Onedrive(); onedrive.ListChanges(); do { // Continue to call ListChanges() until ChangeMarker is the empty string (indicating there // are no more changes to list). onedrive.ListChanges(); } while (onedrive.ChangeMarker.Length > 0); for (int i = 0; i < onedrive.Resources.Count; i++) { // Apply the baseline drive state. } // Now NextChangeMarker will be populated. If we were to call ListChanges() again right now, // nothing would be listed and NextChangeMarker would still be populated. // Wait 2 minutes and then try to list changes again. Assume something changes while we wait. Thread.Sleep(120000); onedrive.ListChanges(); do { onedrive.ListChanges(); } while (onedrive.ChangeMarker.Length > 0); for (int i = 0; i < onedrive.Resources.Count; i++) { // Apply the changes. }

Usage Considerations

• When listing changes, certain resource properties are not included. For example, resource paths are not returned; always use resource Ids when tracking changes.
• It is possible for a resource, uniquely identified by its Id, to appear more than once in a change set. (This can happen if changes are being listed, and then a change occurs before all result pages in the change set are returned; OneDrive will then typically append the new change to the end of the current change set.) Since a OneDrive change always reflects the latest state of a resource, just use the latest one.
• OneDrive will report a change when a resource is created, renamed, modified, or deleted; but it only explicitly specifies deletions. However, it is easy to differentiate between the other change events by keeping track of resource Ids, names, and last modified times; and then comparing old and new values when changes arrive.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

ListDrives Method (OneDrive Class)

Lists the drives accessible by the user.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int ListDrives();

Unicode (Windows)
INT ListDrives();

int cloudstorage_onedrive_listdrives(void* lpObj);

int ListDrives();

Remarks

This method lists the drives accessible to the current user.

Calling this method will fire the DriveList event once for each drive, and will also populate the Drives properties.

If there are still more drives available to list when this method returns, the DriveMarker property will be populated. Continue to call this method until DriveMarker is empty to accumulate all pages of results in the Drives properties. Alternatively, the AccumulatePages configuration setting can be disabled to clear the Drives properties every time a page of results is returned.

The ListDrivesScope configuration setting can be used to control which drives are listed; by default only drives the user directly owns are returned. Refer to ListDrivesScope for more information.

Note: For use-cases that only make use of the current user's default drive (e.g., when authenticated with a personal Microsoft account), there is no need to ever call ListDrives, set the Drive property, or use any of the class's other drive-related API members. By default, the Drive property and the GroupId and SiteId configuration settings are all empty, which causes the class to use the current user's default drive. // DriveList event handler. onedrive.OnDriveList += (s, e) => { Console.WriteLine(e.Name); }; do { onedrive.ListDrives(); for (int i = 0; i < onedrive.Drives.Count; i++) { // Process drives here. } } while (!string.IsNullOrEmpty(onedrive.DriveMarker));

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

ListResources Method (OneDrive Class)

Lists resources in the currently selected folder.

Syntax

• C++
• C

int ListResources();

Remarks

This method lists resources in the folder resource currently selected by RemoteId or RemotePath.

Calling this method will fire the ResourceList event once for each resource, and will also populate the Resources properties.

If there are still more resources available to list when this method returns, the ResourceMarker property will be populated. Continue to call this method until ResourceMarker is empty to accumulate all pages of results in the Resources properties. Alternatively, the AccumulatePages configuration setting can be disabled to clear the Resources properties every time a page of results is returned.

For more complex queries, use the Search method. // ResourceList event handler. onedrive.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; // (Assume that the RemoteId property isn't set; it takes precedence if it is.) onedrive.RemotePath = "/work_files/serious_business/cats"; do { onedrive.ListResources(); for (int i = 0; i < onedrive.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(onedrive.ResourceMarker));

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

SendCustomRequest Method (OneDrive Class)

Sends a custom request to the Microsoft Graph API.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int SendCustomRequest(const char* lpszHttpMethod, const char* lpszRequestPath, const char* lpszRequestBody);

Unicode (Windows)
INT SendCustomRequest(LPCWSTR lpszHttpMethod, LPCWSTR lpszRequestPath, LPCWSTR lpszRequestBody);

int cloudstorage_onedrive_sendcustomrequest(void* lpObj, const char* lpszHttpMethod, const char* lpszRequestPath, const char* lpszRequestBody);

int SendCustomRequest(const QString& qsHttpMethod, const QString& qsRequestPath, const QString& qsRequestBody);

Remarks

This method can be used to send arbitrary requests to the Microsoft Graph API.

Valid values for HttpMethod are:

• GET (default if empty)
• HEAD
• POST
• PUT
• PATCH
• DELETE

The value passed for RequestPath must already be URL-encoded in a manner acceptable to the Microsoft Graph API. The RequestBody parameter may be empty if not needed.

Usage

When this method is called, the class does the following:

1. Builds a request URL, including query parameters, as follows:
   • The specified RequestPath is appended to the Microsoft Graph API's "stable" endpoint, https://graph.microsoft.com/v1.0 (however, see note below).
   • All query parameters in the QueryParams properties are added to the request URL.
2. Sends the request using the specified HttpMethod, the request URL build in step 1, the header information held by Authorization and OtherHeaders, and the given RequestBody (if non-empty).
3. Stores the response headers in the ParsedHeaders properties, and the response body in the stream specified using SetDownloadStream, the specified LocalFile, or ResourceData (using the same logic as DownloadFile).

If the response body is JSON data, the XPath, XText, and other X* configuration settings can then be used to navigate and extract information from it.

Note: Some responses returned by the Graph API include fully-qualified Graph API URLs for clients to use to obtain additional information (the next page of results in a listing, details about a long-running operation, etc.). As a convenience, any fully-qualified URL that begins with https://graph.microsoft.com/ can be passed for RequestPath to have the class make a request against it.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SetDownloadStream Method (OneDrive Class)

Sets the stream to which downloaded data will be written.

Syntax

Unicode (Windows)
INT SetDownloadStream(CloudStorageStream* sDownloadStream);

int cloudstorage_onedrive_setdownloadstream(void* lpObj, CloudStorageStream* sDownloadStream);

int SetDownloadStream(CloudStorageStream* sDownloadStream);

Remarks

If a download stream is set before data is downloaded, the downloaded data will be written to the stream. The stream should be open and normally set to position 0.

Note: Passing a non-null value for DownloadStream will cause LocalFile to be cleared. Similarly, setting LocalFile to a non-empty value will discard any stream set using this method.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

SetUploadStream Method (OneDrive Class)

Sets the stream from which data is read when uploading.

Syntax

int SetUploadStream(CloudStorageStream* sUploadStream);

Unicode (Windows)
INT SetUploadStream(CloudStorageStream* sUploadStream);

int cloudstorage_onedrive_setuploadstream(void* lpObj, CloudStorageStream* sUploadStream);

int SetUploadStream(CloudStorageStream* sUploadStream);

Remarks

If an upload stream is set before data is uploaded, the content of the stream will be read by the class and uploaded to the server. The stream should be open and normally set to position 0.

Note: Passing a non-null value for UploadStream will cause LocalFile to be cleared. Similarly, setting LocalFile to a non-empty value will discard any stream set using this method.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

UpdateResource Method (OneDrive Class)

Updates the currently selected resource.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
int UpdateResource();

Unicode (Windows)
INT UpdateResource();

int cloudstorage_onedrive_updateresource(void* lpObj);

int UpdateResource();

Remarks

This method updates the metadata for the file or folder resource currently selected by RemoteId or RemotePath. For file resources, the file data can optionally be updated as well.

Usage

1. If necessary, call GetResourceInfo or ListResources to ensure an item with the resource's latest information is present in the Resources properties.
2. Modify the item's Resource* fields as desired; the following fields are supported:
   • Description (only updated if not empty; only applicable for OneDrive Personal)
   • Name
   • ParentId (only updated if not empty)
   • ParentPath (only updated if not empty and ParentId is empty)
   If the ClientCreatedTime and/or ClientModifiedTime configuration settings is non-empty, the corresponding timestamps will be sent as well.
3. For file resources, you may call SetUploadStream or set LocalFile or ResourceData if you wish to update the file data on the server. (Refer to UploadFile for more information about simple vs. resumable uploads and encrypting the file data before uploading.)
4. Finally, call this method to update the resource.

Name Conflict Resolution

1. If the RenameIfExists configuration setting is enabled, the server will modify the new name of the resource to be unique, if necessary. Refer to the RenameIfExists configuration setting for more information.
2. Otherwise, if the Overwrite property is enabled, the server will replace the existing (other) resource with the one being updated.
3. Otherwise, the server will return an error.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)

UploadFile Method (OneDrive Class)

Uploads a new file resource.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
char* UploadFile(const char* lpszFileName);

Unicode (Windows)
LPWSTR UploadFile(LPCWSTR lpszFileName);

char* cloudstorage_onedrive_uploadfile(void* lpObj, const char* lpszFileName);

QString UploadFile(const QString& qsFileName);

Remarks

This method uploads a new file resource, with the given FileName (which should include a file extension), to the folder resource currently selected by RemoteId or RemotePath. The Id of the newly-created file resource is returned.

If the ClientCreatedTime and/or ClientModifiedTime configuration settings are non-empty when this method is called, the corresponding timestamps will be submitted with the file upload request.

If SetUploadStream has been used to set an upload stream, it will take priority as the file data source. If LocalFile is set the file will be uploaded from the specified path. If LocalFile is not set the data in ResourceData will be used.

To encrypt the file before uploading it, set EncryptionAlgorithm and EncryptionPassword.

Upload Notes

OneDrive offers two ways to upload a file. For smaller files a simple upload option is provided to upload data in one request. This is the default option. For larger files, uploads can be fragmented into multiple pieces, allowing resuming of uploads that may be interrupted.

Simple

By default the class uses the simple upload mechanism. onedrive.LocalFile = "../MyFile.zip"; onedrive.UploadFile("MyFile.zip");

Resumable

To enable resumable uploads set UseResumableUpload to true. This is recommended for large files. The class will automatically fragment the specified file into smaller pieces and upload each individually. FragmentSize may be set to specify the size of the fragment if desired. The default fragment size is 10 MB.

When UseResumableUpload is set to true and UploadFile is called, a resumable upload session is started by the class. ResumeURL is populated with a URL identifying the session (this value may be needed for additional operations if the upload does not complete normally).

During a resumable upload, the FragmentComplete event fires after each fragment is uploaded to indicate overall progress. The class also updates StartByte as necessary to indicate the current offset in the file.

If the upload is interrupted for any reason, resuming it is easy. First, verify that ResumeURL and StartByte are populated (if the same instance of the class is used, they should already be populated, and no special action should be needed). If uploading from a stream, be sure to reset its position to where it was the first time the upload was started (typically the beginning). Then call UploadFile again to resume the upload at the specified StartByte offset.

Note that if the upload is not resumed after some time the upload session will expire. PollUploadStatus may be used to check the status of a resumable upload, including when it will expire (which is stored in the UploadExpDate configuration setting). An interrupted upload can be aborted explicitly using the AbortUpload method. onedrive.LocalFile = "../MyFile.zip"; onedrive.UploadFile("MyFile.zip"); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte and ResumeURL are already populated from the previous //upload attempt. onedrive.UploadFile("MyFile.zip"); MemoryStream uploadStream = new MemoryStream(File.ReadAllBytes("../MyFile.zip")); onedrive.SetUploadStream(uploadStream); onedrive.UploadFile("MyFile.zip"); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte and ResumeURL are already populated from the previous //upload attempt. //You MUST reset the stream's position to where it was when you first started the upload! uploadStream.Position = 0; onedrive.UploadFile("MyFile.zip");

Name Conflict Resolution

1. If the RenameIfExists configuration setting is enabled, the server will modify the name of the new file resource to be unique. Refer to the RenameIfExists configuration setting for more information.
2. Otherwise, if the Overwrite property is enabled, the server will replace the existing file resource with the newly-uploaded one.
3. Otherwise, the server will return an error.

Error Handling (C++)

This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.

};

// To handle, connect one or more slots to this signal.
void Progress(OneDriveProgressEventParams *e);

// Or, subclass OneDrive and override this emitter function.
virtual int FireProgress(OneDriveProgressEventParams *e) {...}

Remarks

This event fires during an upload or download to indicate the progress of the transfer of the entire request. By default, this event will fire each time PercentDone increases by one percent; the ProgressStep configuration setting can be used to alter this behavior.

Direction indicates whether the transfer is an upload (0) or a download (1).

BytesTransferred reflects the number of bytes that have been transferred so far, or 0 if the transfer is starting (however, see note below).

TotalBytes reflects the total number of bytes that are to be transferred, or -1 if the total is unknown. This amount includes the size of everything in the request like HTTP headers.

PercentDone reflects the overall progress of the transfer, or -1 if the progress cannot be calculated.

Note: By default, the class tracks transfer progress absolutely. If a transfer is interrupted and later resumed, the values reported by this event upon and after resumption will account for the data that was transferred before the interruption.

For example, if 10MB of data was successfully transferred before the interruption, then this event will fire with a BytesTransferred value of 10485760 (10MB) when the transfer is first resumed, and then continue to fire with successively greater values as usual.

This behavior can be changed by disabling the ProgressAbsolute configuration setting, in which case the class will treat resumed transfers as "new" transfers. In this case, the BytesTransferred parameter will always be 0 the first time this event fires, regardless of whether the transfer is new or being resumed.

// Or, subclass OneDrive and override this emitter function.
virtual int FireResourceList(OneDriveResourceListEventParams *e) {...}

Remarks

This event fires once for each resource returned when ListResources, GetResourceInfo, Search, or ListChanges is called.

Id is the Id of the resource.

Name is the name of the resource.

Path is the path to the resource on the server. This parameter will always be empty for ListChanges.

Description holds the description of the resource. This parameter is only applicable for OneDrive Personal.

ResourceType reflects the resource's type. Possible values are:

CreatedTime and ModifiedTime reflect the resource's creation and last modified timestamps. Timestamps are formatted according to ISO 8601 and are always in UTC time.

Size is the size of the resource (for folders, their contents' total size), in bytes. This parameter will always be -1 for ListChanges.

ETag is the ETag of the resource.

Deleted indicates whether the resource has been deleted. This parameter is only applicable for ListChanges, it will always be false otherwise.

SSLServerAuthentication Event (OneDrive Class)

Fired after the server presents its certificate to the client.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSLServerAuthentication(OneDriveSSLServerAuthenticationEventParams *e);

typedef struct {
  const char *CertEncoded;
  int lenCertEncoded;
  const char *CertSubject;
  const char *CertIssuer;
  const char *Status;
  int Accept;
  int reserved;
} OneDriveSSLServerAuthenticationEventParams;


Unicode (Windows)
virtual INT FireSSLServerAuthentication(OneDriveSSLServerAuthenticationEventParams *e);

typedef struct {
  LPCSTR CertEncoded;
  INT lenCertEncoded;
  LPCWSTR CertSubject;
  LPCWSTR CertIssuer;
  LPCWSTR Status;
  BOOL Accept;
  INT reserved;
} OneDriveSSLServerAuthenticationEventParams;

#define EID_ONEDRIVE_SSLSERVERAUTHENTICATION 9

virtual INT CLOUDSTORAGE_CALL FireSSLServerAuthentication(LPSTR &lpCertEncoded, INT &lenCertEncoded, LPSTR &lpszCertSubject, LPSTR &lpszCertIssuer, LPSTR &lpszStatus, BOOL &bAccept);

class OneDriveSSLServerAuthenticationEventParams {
public:
  const QByteArray &CertEncoded();

  const QString &CertSubject();

  const QString &CertIssuer();

  const QString &Status();

  bool Accept();
  void SetAccept(bool bAccept);

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSLServerAuthentication(OneDriveSSLServerAuthenticationEventParams *e);

// Or, subclass OneDrive and override this emitter function.
virtual int FireSSLServerAuthentication(OneDriveSSLServerAuthenticationEventParams *e) {...}

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (OneDrive Class)

Fired when secure connection progress messages are available.

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireSSLStatus(OneDriveSSLStatusEventParams *e);

typedef struct {
  const char *Message;
  int reserved;
} OneDriveSSLStatusEventParams;


Unicode (Windows)
virtual INT FireSSLStatus(OneDriveSSLStatusEventParams *e);

typedef struct {
  LPCWSTR Message;
  INT reserved;
} OneDriveSSLStatusEventParams;

#define EID_ONEDRIVE_SSLSTATUS 10

virtual INT CLOUDSTORAGE_CALL FireSSLStatus(LPSTR &lpszMessage);

class OneDriveSSLStatusEventParams {
public:
  const QString &Message();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void SSLStatus(OneDriveSSLStatusEventParams *e);

// Or, subclass OneDrive and override this emitter function.
virtual int FireSSLStatus(OneDriveSSLStatusEventParams *e) {...}

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (OneDrive Class)

This event fires when a document starts transferring (after the headers).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireStartTransfer(OneDriveStartTransferEventParams *e);

typedef struct {
  int Direction;
  int reserved;
} OneDriveStartTransferEventParams;


Unicode (Windows)
virtual INT FireStartTransfer(OneDriveStartTransferEventParams *e);

typedef struct {
  INT Direction;
  INT reserved;
} OneDriveStartTransferEventParams;

#define EID_ONEDRIVE_STARTTRANSFER 11

virtual INT CLOUDSTORAGE_CALL FireStartTransfer(INT &iDirection);

class OneDriveStartTransferEventParams {
public:
  int Direction();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void StartTransfer(OneDriveStartTransferEventParams *e);

// Or, subclass OneDrive and override this emitter function.
virtual int FireStartTransfer(OneDriveStartTransferEventParams *e) {...}

Remarks

The StartTransfer event is fired when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Transfer Event (OneDrive Class)

Fired while a document transfers (delivers document).

Syntax

• C++
• C
• Qt

ANSI (Cross Platform)
virtual int FireTransfer(OneDriveTransferEventParams *e);

typedef struct {
  int Direction;
  int64 BytesTransferred;
  int PercentDone;
  const char *Text;
  int lenText;
  int reserved;
} OneDriveTransferEventParams;


Unicode (Windows)
virtual INT FireTransfer(OneDriveTransferEventParams *e);

typedef struct {
  INT Direction;
  LONG64 BytesTransferred;
  INT PercentDone;
  LPCSTR Text;
  INT lenText;
  INT reserved;
} OneDriveTransferEventParams;

#define EID_ONEDRIVE_TRANSFER 12

virtual INT CLOUDSTORAGE_CALL FireTransfer(INT &iDirection, LONG64 &lBytesTransferred, INT &iPercentDone, LPSTR &lpText, INT &lenText);

class OneDriveTransferEventParams {
public:
  int Direction();

  qint64 BytesTransferred();

  int PercentDone();

  const QByteArray &Text();

  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Transfer(OneDriveTransferEventParams *e);

// Or, subclass OneDrive and override this emitter function.
virtual int FireTransfer(OneDriveTransferEventParams *e) {...}

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
