The GoogleDrive component makes it easy to upload, download, and manage files and folders within Google Drive.

Syntax

TcsGoogleDrive

Remarks

The GoogleDrive component provides an easy-to-use interface for Google Drive. Capabilities include uploading and downloading files, file and folder manipulation and organization, Google Shared Drive support, strong client-side file encryption functionality, and more.

Authentication

This component requires authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth* properties to set the appropriate fields for the chosen OAuthClientProfile and OAuthGrantType.

The component has the following defaults:

Below is a brief description of the different OAuthClientProfile and OAuthGrantType values that are supported by this component. 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 component. 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 OAuthAccessToken property will be populated. Additionally, if a refresh token was provided the OAuthRefreshToken property will be populated as well. These values of the fields are for informational purposes. The component will also cache these tokens along with when the OAuthAccessToken will be expired. When a method that makes requests to the service provider is called or the Authorize method is called the component will automatically check to see if the access token is expired. If it is, it will then automatically try to get a new OAuthAccessToken. If the Authorize method was not used and user interaction would be required, the component will throw an error which can be caught. When user interaction is needed depends on what grant type is set in the OAuthGrantType property. 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 OAuthGrantType property are below. For more information, see the service documentation.

Authorization Code

When using the Authorization Code grant type, the component will use an authorization code to get an access token. For this OAuthGrantType the component expects a OAuthClientId, OAuthClientSecret, OAuthServerAuthURL, and OAuthServerTokenURL 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 component will parse the authorization code, setting the OAuthAuthorizationCode property, from the redirect. Immediately, the component 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 OAuthRefreshToken property is set, or a refresh token is cached, then the component will not launch the browser and use the refresh token in its request to the token server instead of an authorization code.

Example: GoogleDrive googledrive = new GoogleDrive(); googledrive.OAuth.ClientProfile = OAuthClientProfiles.cocpApplication; googledrive.OAuth.GrantType = OAuthGrantTypes.cogtAuthorizationCode; googledrive.OAuth.ClientId = CLIENT_ID; googledrive.OAuth.ClientSecret = CLIENT_SECRET; googledrive.Authorize();

Implicit

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

When using the Implicit grant type, the component will request the authorization server to get an access token. For this OAuthGrantType the component expects a OAuthClientId, OAuthClientSecret, and OAuthServerAuthURL 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 component 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 component will not be able to automatically get a fresh token once it expires.

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 component to ignore the values set in the OAuth property.

For Example: Oauth oauth = new Oauth(); oauth.ClientId = "CLIENT_ID"; oauth.ClientSecret = "CLIENT_SECRET"; oauth.AuthorizationScope = "https://www.googleapis.com/auth/gmail.readonly"; oauth.ServerAuthURL = "https://accounts.google.com/o/oauth2/auth"; oauth.ServerTokenURL = "https://www.googleapis.com/auth/drive"; oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode; googledrive.Authorization = oauth.GetAuthorization(); Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

Listing Resources

The ListResources method is used to list resources within the scope specified by the ListResourcesScope property.

The ListChildren, ListParents, and GetResourceInfo methods are also available for finer-grained control. // ResourceList event handler. googledrive.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; // List all of the current user's resources. googledrive.ListResourcesScope = GoogledriveListResourcesScopes.lrsUser; do { googledrive.ListResources(); for (int i = 0; i < googledrive.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(googledrive.ResourceMarker)); // List all of the resources in the specified shared drive. googledrive.SharedDrive = "wfsr789vusijfv"; googledrive.ListResourcesScope = GoogledriveListResourcesScopes.lrsSharedDrive; do { googledrive.ListResources(); for (int i = 0; i < googledrive.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(googledrive.ResourceMarker));

Downloading Files

The DownloadFile method is used to download files.

Download Notes

To decrypt an encrypted file set EncryptionAlgorithm and EncryptionPassword before calling this method. googledrive.LocalFile = "../MyFile.zip"; googledrive.DownloadFile(googledrive.Resources[0].Id, "");

Resuming Downloads

The component 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"; googledrive.LocalFile = downloadFile; googledrive.DownloadFile(googledrive.Resources[0].Id, ""); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially downloaded file googledrive.StartByte = new FileInfo(downloadFile).Length; googledrive.DownloadFile(googledrive.Resources[0].Id, "");

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 component 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. googledrive.LocalFile = "../MyFile.zip"; googledrive.EncryptionPassword = "password"; googledrive.DownloadFile(googledrive.Resource[0].Id, ""); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially download temp file googledrive.StartByte = new FileInfo(googledrive.Config("DownloadTempFile")).Length; googledrive.DownloadFile(googledrive.Resource[0].Id, "");

Uploading Files

The UploadFile method is used to upload files.

Upload Notes

Google Drive 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 component uses the simple upload mechanism. googledrive.LocalFile = "../MyFile.zip"; googledrive.UploadFile("MyFile.zip", "");

Resumable

To enable resumable uploads set UseResumableUpload to true. This is recommended for large files. The component 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 component. 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 component 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 component is used, they should already be populated, and no special action should be needed). 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. GetUploadStatus may be used to check the status of a resumable upload. googledrive.LocalFile = "../MyFile.zip"; googledrive.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. googledrive.UploadFile("MyFile.zip", "");

Shared Drive Support

The GoogleDrive component has full support for Google Shared Drives. For the most common use-cases (such as those described above), there is very little difference when using a shared drive versus a personal Google Drive ("My Drive").

For more information about how to use the component with Google Shared Drives, refer to both the shared-drive-specific documentation sections for commonly-used methods like ListResources, MoveResource, UpdatePermissions, etc.; and browse through the documentation for shared-drive-specific methods and properties such as the AddSharedDriveMember and ListSharedDrives methods, the SharedDrive property, etc.

Additional Functionality

The GoogleDrive component offers advanced functionality beyond simple uploads and downloads. For instance:

• Encrypt and decrypt files using the EncryptionAlgorithm and EncryptionPassword properties.
• Basic file and folder manipulation and organization using methods such as CopyResource, CreateFolder, DeleteResource, MoveResource, and UpdateResource.
• Enumeration and manipulation of parent-child relationships using the AddParents, ListChildren, ListParents, and RemoveParents methods.
• Resourcing trashing and deletion: DeleteResource, TrashResource, RestoreResource.
• Control over permissions using ListPermissions and UpdatePermissions.
• Change tracking with ListChanges.
• And more!

Syntax

__property int Timeout = { read=FTimeout, write=FSetTimeout };

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 component will wait for the operation to complete before returning control.

The component 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 component raises an exception.

Please note that by default, all timeouts are inactivity timeouts, i.e. 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.

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

AddSharedDriveMember Method (GoogleDrive Component)

Creates a new shared drive member.

Syntax

String __fastcall AddSharedDriveMember(String SharedDriveId, int Role, int PermissionType, String Email);

Remarks

This is a convenience method that adds a new member to the shared drive specified by SharedDriveId by creating a permission on that shared drive. The Id of the newly-created permission is returned.

Role specifies the member's role. Valid values are:

PermissionType must be one of:

• 0 (ptUser) - A single user.
• 1 (ptGroup) - A group.

Email specifies the email address of the user or the group.

Refer to UpdatePermissions for more information about how permissions work in general, how permissions relate to shared drive members, and how to manipulate multiple members at once. string sharedDriveId = "20983euijdsds"; // First, we'll add a new member to the shared drive. The two integer parameters signify: // * The role type. 2 is the "Writer" role, which provides read and write (but not organize) permissions. // * The permission type. 0 means this is a single user (versus a group). // The Id of the new permission we've created on the shared drive--which is what actually causes the user to // be a member of the shared drive--is returned. string permId = googledrive.AddSharedDriveMember(sharedDriveId, 2, 0, "fakeuser@example.com"); // At some point later, perhaps this user has abused their privileges and we wish to revoke their writer // permissions. We change their role to "Commenter", which provides reader and commenting permissions. googledrive.UpdateSharedDriveMember(sharedDriveId, permId, 1); // 1 is the "Commenter" role. // Or perhaps we wish to simply remove the user's shared drive membership completely. googledrive.RemoveSharedDriveMember(sharedDriveId, permId);

Authorize Method (GoogleDrive Component)

Get the authorization string required to access the protected resource.

Syntax

void __fastcall 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 OAuthClientProfile property and the OAuthGrantType property. This method is not to be used in conjunction with the Authorization property. It should instead be used when setting the OAuth* properties.

For more information, see the introduction section.

CalcAuthorization Method (GoogleDrive Component)

Calculates the Authorization header based on provided credentials.

Syntax

void __fastcall 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 component 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.

Config Method (GoogleDrive Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

CopyResource Method (GoogleDrive Component)

Copies a file.

Syntax

String __fastcall CopyResource(String ResourceId, String NewName, String ParentIds);

Remarks

This method copies the file identified by ResourceId and returns the Id of the newly created copy.

The NewName parameter defines the name of the copied file.

The ParentIds parameter should be a comma-separated list of existing folder Ids to use as parents for the copied file. If left blank, the copied file will inherit the same parents of the original.

CreateFolder Method (GoogleDrive Component)

Creates a new folder.

Syntax

String __fastcall CreateFolder(String Name, String ParentIds);

Remarks

This method creates a new folder with the specified Name and returns its Id. ParentIds can be a list of existing folder Ids to use as parents for the new folder, or empty string to create the folder at the root of the drive.

If the IncludeFolderProperties configuration setting is true when this method is called, the component will include the metadata held by the first item in the Resource* properties when creating the folder. (Note that the Name and ParentIds passed to this method will take precedence.)

Google treats files and folders in the same way, and folders are included when listing resources. The ResourceType property can be used to determine if a resource is a folder, a file, or a revision of a file.

To list, delete, and update folders use the ListResources, DeleteResource, and UpdateResource methods.

CreateSharedDrive Method (GoogleDrive Component)

Creates a new shared drive.

Syntax

String __fastcall CreateSharedDrive(String Name, String RequestId);

Remarks

This method creates a new shared drive and returns the newly-created shared drive's Id.

Name is the name of the new shared drive.

RequestId is a unique value used by the server to identify an idempotent request by the current user to create a shared drive. (That is, the server ensures that duplicate shared drives are not created if any given user makes repeated shared drive creation requests with the same Name and RequestId.)

DeleteResource Method (GoogleDrive Component)

Deletes the specified file or folder permanently.

Syntax

void __fastcall DeleteResource(String ResourceId);

Remarks

This method deletes the file or folder specified by ResourceId permanently.

Files and folders are not moved to the trash, they are deleted permanently. You can use TrashResource to move files or folders to the trash.

DeleteSharedDrive Method (GoogleDrive Component)

Deletes a shared drive.

Syntax

void __fastcall DeleteSharedDrive(String SharedDriveId);

Remarks

This method deletes the shared drive specified by SharedDriveId.

Note that only members of a shared drive with the prOrganizer (5) role can delete it, and that the shared drive must be empty (or all of its items must be in the trash).

DownloadFile Method (GoogleDrive Component)

Downloads, and optionally converts, a file.

Syntax

void __fastcall DownloadFile(String ResourceId, String MimeType);

Remarks

This method downloads the file specified by ResourceId.

If LocalFile is set, the file will be saved to the specified location; otherwise, the file data will be held by ResourceData.

If the empty string is passed for MimeType, the file will be downloaded as-is. If the file is in one of the Google formats shown in the table below, one of the MIME types shown in the third column can be passed for MimeType instead to convert the file before downloading it.

Download Notes

To decrypt an encrypted file set EncryptionAlgorithm and EncryptionPassword before calling this method. googledrive.LocalFile = "../MyFile.zip"; googledrive.DownloadFile(googledrive.Resources[0].Id, "");

Resuming Downloads

The component 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"; googledrive.LocalFile = downloadFile; googledrive.DownloadFile(googledrive.Resources[0].Id, ""); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially downloaded file googledrive.StartByte = new FileInfo(downloadFile).Length; googledrive.DownloadFile(googledrive.Resources[0].Id, "");

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 component 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. googledrive.LocalFile = "../MyFile.zip"; googledrive.EncryptionPassword = "password"; googledrive.DownloadFile(googledrive.Resource[0].Id, ""); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially download temp file googledrive.StartByte = new FileInfo(googledrive.Config("DownloadTempFile")).Length; googledrive.DownloadFile(googledrive.Resource[0].Id, "");

EmptyTrash Method (GoogleDrive Component)

Permanently deletes all of the current user's trashed files.

Syntax

void __fastcall EmptyTrash();

Remarks

This method permanently deletes all of the current user's trashed files by emptying the trash for their "My Drive".

It is not possible to recover trashed files after this method is called!

GetAccountInfo Method (GoogleDrive Component)

Gets information about the current user's account and space usage.

Syntax

void __fastcall GetAccountInfo();

Remarks

This method gets information about the current user's account and space usage, populating the Account* properties.

GetCurrentChangeMarker Method (GoogleDrive Component)

Gets the most current change marker.

Syntax

void __fastcall GetCurrentChangeMarker();

Remarks

This method populates NextChangeMarker with the most current change marker available.

Refer to ListChanges for more information.

If SharedDrive is set, this method will get the most current change marker available for that shared drive's changes.

GetPermissionInfo Method (GoogleDrive Component)

Gets information about a specific permission.

Syntax

void __fastcall GetPermissionInfo(String ResourceId, String PermissionId);

Remarks

This method retrieves information about the permission specified by PermissionId on the file, folder, or shared drive specified by ResourceId.

Calling this method will fire the PermissionList event, and will populate the Permission* properties (clearing any previously-held items in the process).

Shared Drive Members

GetResourceInfo Method (GoogleDrive Component)

Gets information about specific files and folders.

Syntax

void __fastcall GetResourceInfo(String ResourceIds);

Remarks

This method retrieves information about the file and folder resources specified by ResourceIds (which should be specified as a comma-separated list of resource Ids).

Calling this method will fire the ResourceList event once for each resource, and will populate the Resource* properties (clearing any previously-held items in the process).

Note that, unlike the ListResources and ListChildren methods, this method uses the resource Ids to retrieve information directly. This means that it does not support paged results or complex search queries (the "q" query parameter), does not need to know whether the resources are in shared drives, etc.

GetSharedDriveInfo Method (GoogleDrive Component)

Gets information about a specific shared drive.

Syntax

void __fastcall GetSharedDriveInfo(String SharedDriveId);

Remarks

This method retrieves information about the shared drive specified by SharedDriveId.

Calling this method will fire the SharedDriveList event, and will populate the SharedDrive* properties (clearing any previously-held items in the process).

GetUploadStatus Method (GoogleDrive Component)

Gets the status of a resumable upload session.

Syntax

void __fastcall GetUploadStatus();

Remarks

This method gets the status of a resumable upload session. Set ResumeURL before calling this method. After calling this method StartByte will be populated.

Interrupt Method (GoogleDrive Component)

Interrupt the current method.

Syntax

void __fastcall Interrupt();

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ListChanges Method (GoogleDrive Component)

Lists changes to resources and shared drives.

Syntax

void __fastcall ListChanges();

Remarks

This method lists changes to resources and shared drives.

General Usage

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 Change* properties. (Once there aren't any more changes available to list, the NextChangeMarker property will be populated instead.)

Calling GetCurrentChangeMarker will immediately populate NextChangeMarker. Regardless of whether it is populated because of a call to GetCurrentChangeMarker or to ListChanges, NextChangeMarker 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.)

Setting ChangeMarker to "1" will cause ListChanges to list changes beginning with the very first change available.

Example of Listing Changes // Start listing changes from the beginning, and list a maximum of 10 changes at a time. googledrive.ChangeMarker = "1"; googledrive.Config("MaxResults=10"); // List changes once. googledrive.ListChanges(); do { for (int i = 0; i < googledrive.Changes.Count; i++) { Console.WriteLine(googledrive.Changes[i].ResourceId); Console.WriteLine(googledrive.Changes[i].Time); Console.WriteLine(googledrive.Changes[i].Removed); } // Continue to call ListChanges() until ChangeMarker is the empty string (indicating there // are no more changes to list). googledrive.ListChanges(); } while (googledrive.ChangeMarker.Length > 0); // 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. Thread.Sleep(120000); googledrive.ListChanges(); do { for (int i = 0; i < googledrive.Changes.Count; i++) { Console.WriteLine(googledrive.Changes[i].ResourceId); Console.WriteLine(googledrive.Changes[i].Time); Console.WriteLine(googledrive.Changes[i].Removed); } googledrive.ListChanges(); } while (googledrive.ChangeMarker.Length > 0);

Shared Drive Functionality

If SharedDrive is empty string, then changes for items in shared drives that the user has accessed will be included (in addition to the usual changes for the user's items). Changes to the shared drives themselves which the user is a member of will also be included.

If SharedDrive is populated with a shared drive resource Id, then only changes to items within that shared drive, as well as changes to that shared drive itself, will be returned.

A change's ChangeType will reflect whether it is associated with a file or folder (0), or a shared drive itself (1).

ListChildren Method (GoogleDrive Component)

Lists the child resources of one or more folders.

Syntax

void __fastcall ListChildren(String FolderIds);

Remarks

This is a convenience method that works the same way as ListResources, but limits the results to children of one or more folders specified by FolderIds (which should be specified as a comma-separated list of folder resource Ids).

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

If there are still more child resources available to list when this method returns, the ChildMarker property will be populated. Continue to call this method until ChildMarker is empty to accumulate all pages of results in the Child* properties.

Note that the string "root" may be used as a folder Id to represent the root folder of a drive.

Refer to ListResources for more information about how listing resources works in general, everything there applies to this method too. // ResourceList event handler. googledrive.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; // List all of the children of the given folder resource. do { googledrive.ListChildren("12978eyuihusd"); for (int i = 0; i < googledrive.Children.Count; i++) { // Process child resources here. } } while (!string.IsNullOrEmpty(googledrive.ChildMarker));

ListParents Method (GoogleDrive Component)

Lists the parent folders of a file or folder.

Syntax

void __fastcall ListParents(String ResourceId);

Remarks

This is a convenience method that simply retrieves the parent Ids of the file or folder specified by ResourceId and passes them to GetResourceInfo.

Refer to GetResourceInfo for more information.

ListPermissions Method (GoogleDrive Component)

Lists the permissions for a file, folder, or shared drive.

Syntax

void __fastcall ListPermissions(String ResourceId);

Remarks

This method is used to list permissions for the file, folder, or shared drive specified by ResourceId.

Calling this method will fire the PermissionList event once for each permission, and will also populate the Permission* properties.

If there are still more permissions available to list when this method returns, the PermissionMarker property will be populated. Continue to call this method until PermissionMarker is empty to accumulate all pages of results in the Permission* properties. // PermissionList event handler. googledrive.OnPermissionList += (s, e) => { Console.WriteLine("Permission Id: " + e.Id); }; // List all of the permissions on the given resource. do { googledrive.ListPermissions("fdjhskdf89o3wi"); for (int i = 0; i < googledrive.Permissions.Count; i++) { // Process permissions here. } } while (!string.IsNullOrEmpty(googledrive.PermissionMarker));

Shared Drive Members

Shared Drive Capabilities

ListResources Method (GoogleDrive Component)

Lists files and folders.

Syntax

void __fastcall ListResources();

Remarks

This method is used to list file and folders. Calling this method will fire the ResourceList event once for each resource, and will also populate the Resource* 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 Resource* properties.

Listing Resources

To simply list the children or parents of specific resources, use ListChildren or ListParents. To retrieve information about specific resources, use GetResourceInfo.

For more complex queries, refer to the Google Drive API documentation for information on how to construct a search query, then use the AddQueryParam method to add a query parameter named "q" to the QueryParam* properties before calling this method.

Result Scopes

When ListResources is called with ListResourcesScope set to the default of lrsUser (0), the results will consist of items that are in the current user's "My Drive" and "Shared with me" spaces.

If ListResourcesScope is set to lrsDomain (1), the results will instead consist of items which have been shared to the current user's domain, whether or not the user has actually accessed them.

(To clarify, items shared to a user's domain are only added to their "Shared with me" space once the user accesses them for the first time. So, items shared to a user's domain that they have not actually accessed before would not show up when ListResourcesScope is set to lrsUser (0), but would show up when it is set to lrsDomain (1).)

When ListResourcesScope is set to lrsSharedDrive (2), the SharedDrive property must be set to the resource Id of a shared drive, and the results of this method will consist only of items within that shared drive.

When ListResourcesScope is set to lrsAllDrives (3), the results will consist of anything in the user's "My Drive" and "Shared with me" spaces, and all items in all shared drives which the user is a member of.

Note: Under some circumstances, if a user is a member of many shared drives, using the lrsAllDrives (3) will not yield a complete set of results (even with paged results). This is a direct limitation of the Google Drive API, and the only solution is to use a narrower scope. When using the lrsAllDrives (3) scope, you should check the SearchIncomplete configuration setting after calling ListResources; it will return "True" if the result set is incomplete.

How Shared Drives Work

Just like a real user, a shared drive itself owns the files in its storage space (this is why the permissions for members of a shared drive use the "file organizer" and "organizer" roles instead of the "owner" role). Also like a real user, a shared drive's files can be explicitly shared with other users (even if they aren't members of the shared drive), and with the overall domain.

The difference, of course, is that a shared drive has a defined set of members, all of which have access to everything in the shared drive (though with varying capabilities). Refer to UpdatePermissions, AddSharedDriveMember, UpdateSharedDriveMember, and RemoveSharedDriveMember for more information. // ResourceList event handler. googledrive.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; // List all of the current user's resources. googledrive.ListResourcesScope = GoogledriveListResourcesScopes.lrsUser; do { googledrive.ListResources(); for (int i = 0; i < googledrive.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(googledrive.ResourceMarker)); // List all of the resources in the specified shared drive. googledrive.SharedDrive = "wfsr789vusijfv"; googledrive.ListResourcesScope = GoogledriveListResourcesScopes.lrsSharedDrive; do { googledrive.ListResources(); for (int i = 0; i < googledrive.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(googledrive.ResourceMarker));

ListRevisions Method (GoogleDrive Component)

List the revisions of a file.

Syntax

void __fastcall ListRevisions(String FileId);

Remarks

This method will list the revisions of the specified file. Calling this method will fire the ResourceList event once for each revision, and will also populate the Resource* properties. The Revision ID will be help in the ResourceId property.

If the Revision ID is set to the RevisionId configuration setting, the following methods can be used to interact with the specific revision:

• DeleteResource
• DownloadFile
• GetResourceInfo
• UpdateResource

After these methods are no longer needed, it is recommended to clear to the RevisionId configuration setting to avoid unattended changes to functionality.

ListSharedDrives Method (GoogleDrive Component)

Lists shared drives that the current user is a member of.

Syntax

void __fastcall ListSharedDrives();

Remarks

This method lists the shared drives which the current user is a member of.

Calling this method will fire the SharedDriveList event once for each shared drive, and will also populate the SharedDrive* properties.

If there are still more shared drives available to list when this method returns, the SharedDriveMarker property will be populated. Continue to call this method until SharedDriveMarker is empty to accumulate all pages of results in the SharedDrive* properties. // SharedDriveList event handler. googledrive.OnSharedDriveList += (s, e) => { Console.WriteLine(e.Name); }; // List all shared drives the current user is a member of. do { googledrive.ListSharedDrives(); for (int i = 0; i < googledrive.SharedDrives.Count; i++) { // Process shared drives here. } } while (!string.IsNullOrEmpty(googledrive.SharedDriveMarker));

MoveResource Method (GoogleDrive Component)

Moves a file or folder.

Syntax

void __fastcall MoveResource(String ResourceId, String NewParentIds);

Remarks

This method "moves" an existing file or folder specified by ResourceId to the folders specified by NewParentIds (which should be specified as a comma-separated list of folder resource Ids).

After this method returns, the folders specified by NewParentIds will be the only parents of in the resource's parent list. If you wish to add additional parents for the resource without removing its existing parents, use AddParents instead.

Note that resources within a shared drive must always have exactly one parent, and that only shared drive members with the "file organizer" or "organizer" roles can move files and folders within a shared drive.

RemoveParents Method (GoogleDrive Component)

Removes folders from the list of parents for a file or folder.

Syntax

void __fastcall RemoveParents(String ResourceId, String ParentIds);

Remarks

This method removes one or more folders, specified by ParentIds, from the list of parents for the file or folder specified by ResourceId.

ParentIds should be specified as a comma-separated list of one or more resource Ids.

Note that resources within a shared drive must always have exactly one parent, and that only shared drive members with the "file organizer" or "organizer" roles can move files and folders within a shared drive.

RemoveSharedDriveMember Method (GoogleDrive Component)

Removes an existing shared drive member.

Syntax

void __fastcall RemoveSharedDriveMember(String SharedDriveId, String PermissionId);

Remarks

This is a convenience method that removes an existing member of a shared drive (specified by SharedDriveId) by deleting their associated permission (specified by PermissionId).

Refer to UpdatePermissions for more information about how permissions work in general, how permissions relate to shared drive members, and how to manipulate multiple members at once. string sharedDriveId = "20983euijdsds"; // First, we'll add a new member to the shared drive. The two integer parameters signify: // * The role type. 2 is the "Writer" role, which provides read and write (but not organize) permissions. // * The permission type. 0 means this is a single user (versus a group). // The Id of the new permission we've created on the shared drive--which is what actually causes the user to // be a member of the shared drive--is returned. string permId = googledrive.AddSharedDriveMember(sharedDriveId, 2, 0, "fakeuser@example.com"); // At some point later, perhaps this user has abused their privileges and we wish to revoke their writer // permissions. We change their role to "Commenter", which provides reader and commenting permissions. googledrive.UpdateSharedDriveMember(sharedDriveId, permId, 1); // 1 is the "Commenter" role. // Or perhaps we wish to simply remove the user's shared drive membership completely. googledrive.RemoveSharedDriveMember(sharedDriveId, permId);

Reset Method (GoogleDrive Component)

Resets the component to its initial state.

Syntax

void __fastcall Reset();

Remarks

This method resets the component to its initial state.

RestoreResource Method (GoogleDrive Component)

Restores a file or folder from the trash.

Syntax

void __fastcall RestoreResource(String ResourceId);

Remarks

This method restores the file or folder specified by ResourceId from the trash.

SendCustomRequest Method (GoogleDrive Component)

Sends a custom request to the Google Drive API.

Syntax

void __fastcall SendCustomRequest(String HttpMethod, String RequestPath, String RequestBody);

Remarks

This method can be used to send arbitrary requests to the Google Drive 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 Google Drive API. The RequestBody parameter may be empty if not needed.

Usage

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

1. Builds a request URL, including query parameters, as follows:
   • The specified RequestPath is appended to the Google Drive API endpoint, https://www.googleapis.com/drive/v3.
   • All query parameters in the QueryParam* 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 ParsedHeader* properties, and the response body in 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.

ToggleSharedDriveHidden Method (GoogleDrive Component)

Hides or unhides a shared drive.

Syntax

void __fastcall ToggleSharedDriveHidden(String SharedDriveId, bool Hidden);

Remarks

This method hides or unhides the shared drive specified by SharedDriveId.

If a shared drive is hidden, it will not show up in the Google Drive UI by default (but is still otherwise accessible). Google Drive tracks this setting separately for each user; i.e., each member of a shared drive can choose whether the shared drive should be hidden or not.

TrashResource Method (GoogleDrive Component)

Moves the specified file or folder to the trash.

Syntax

void __fastcall TrashResource(String ResourceId);

Remarks

This method moves the file or folder specified by ResourceId to the trash. The resource may be restored from the trash by calling RestoreResource.

To permanently delete a resource, call DeleteResource. To empty the trash (thus permanently deleting all trashed items), call EmptyTrash.

UpdatePermissions Method (GoogleDrive Component)

Create, update, and delete permissions on a file, folder, or shared drive.

Syntax

void __fastcall UpdatePermissions(String ResourceId);

Remarks

This method is used to create, update, and delete permissions for the file, folder, or shared drive specified by ResourceId.

Each item represented by the Permission* properties has a PermissionModOp property which can be set to one of the following values:

When this method is called, the component will iterate through the Permission* properties and execute the requested operation for each permission.

For each permission operation which completes successfully, the component will change its PermissionModOp property back to moNone (0).

Important: The component executes permission operations one-by-one due to how the Google Drive API works. If the component encounters an issue during one of the operations, it will fail with an error, and won't attempt to execute any remaining permission items' operations. The error message will indicate the index of the permission item which caused the error.

Usage

To create new permissions, add new items to the Permission* properties by incrementing the PermissionCount property as necessary.

For each permission being created or updated, set its properties to the desired values. The PermissionModOp property should be set to a value other than moNone (0) for any permission that should be created, updated, or deleted.

Once the permission items have been set up as desired, call this method. // For simplicity's sake, assume that this file currently has no permissions on it. string fileId = "awd0s79uocijl23wf"; // Add permissions for a couple of users to the file. googledrive.Permissions.Add(new GDrivePermission() { Email = "fakeuser1@example.com", Role = GDrivePermissionRoles.prReader, ModOp = GDrivePermissionModOps.moCreate }); googledrive.Permissions.Add(new GDrivePermission() { Email = "fakeuser2@example.com", Role = GDrivePermissionRoles.prWriter, ModOp = GDrivePermissionModOps.moCreate }); googledrive.UpdatePermissions(fileId); // Now we'll update the permissions on the file, removing one of the users and // changing the other's role to "Commenter". Always list the permissions first // to ensure that the latest data is loaded into the component. googledrive.ListPermissions(fileId); googledrive.Permissions[0].ModOp = GDrivePermissionModOps.moDelete; googledrive.Permissions[1].Role = GDrivePermissionRoles.prCommenter; googledrive.Permissions[1].ModOp = GDrivePermissionModOps.moUpdate; // Now commit the changes. googledrive.UpdatePermissions(fileId);

Transferring Ownership

Note that this does not apply to shared drives themselves, or resources in shared drives. It also does not apply when moving resources into or out of shared drives.

Shared Drive Permissions

Since members are determined by the permissions on a shared drive, this method can of course be used to manipulate one or more shared drive members at once. For simpler use cases which only need to modify one member at a time, the AddSharedDriveMember, UpdateSharedDriveMember, and RemoveSharedDriveMember convenience methods can be used.

Note: Only the ptUser (0) and ptGroup (1) permission types are valid for permissions on a shared drive itself.

Just like in a regular user's drive, permissions can also be applied to files within a shared drive to explicitly share them with specific users (whether they're members of the shared drive or not).

UpdateResource Method (GoogleDrive Component)

Updates a file or folder.

Syntax

void __fastcall UpdateResource(String ResourceId);

Remarks

This method updates the metadata for the file or folder resource identified by ResourceId. 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 Resource* properties.
2. Modify the item's Resource* properties as desired; the following properties are supported:
   • ResourceContentAccessible
   • ResourceDescription
   • ResourceMIMEType (only updated for files, if not empty and new file data is uploaded)
   • ResourceModifiedTime (only updated if not empty)
   • ResourceName
   • ResourceStarred
   • ResourceTrashed
3. For file resources, you may 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.

UpdateSharedDrive Method (GoogleDrive Component)

Updates a shared drive.

Syntax

void __fastcall UpdateSharedDrive(String SharedDriveId, String NewName, int SetRestrictions, int UnsetRestrictions);

Remarks

This method updates the name of and/or restrictions applied to the shared drive specified by SharedDriveId.

If the current user is allowed to rename the shared drive (i.e., if the SharedDriveCapabilities property has the 0x08000 flag set), then a new name can be provided using the NewName parameter. If the user is not allowed to rename the shared drive, or wishes to preserve its current name, pass empty string for NewName.

Similarly, if the current user is allowed to alter one or more of the shared drive's SharedDriveRestrictions (i.e., if the SharedDriveCapabilities property has the 0x00002, 0x00004, and/or 0x00010 flags set), then the desired restrictions can be set or unset by including their associated flags, listed below, in the values passed for the SetRestrictions and UnsetRestrictions parameters.

Note that calls to this method will fail if:

• A non-empty string is passed for NewName, but the current user isn't allowed to rename the shared drive.
• The values passed for SetRestrictions and/or UnsetRestrictions contains any flag that corresponds to a restriction the current user isn't allowed to alter.
• Any restriction flag appears in both SetRestrictions and UnsetRestrictions.

Changes requested using this method are "all-or-nothing"; e.g., if both a new name and a new set of restrictions are requested, but the current user isn't allowed to rename the shared drive, the entire request fails.

UpdateSharedDriveMember Method (GoogleDrive Component)

Updates an existing shared drive member's role.

Syntax

void __fastcall UpdateSharedDriveMember(String SharedDriveId, String PermissionId, int Role);

Remarks

This is a convenience method that updates the role of an existing member of a shared drive (specified by SharedDriveId) by modifying their associated permission (specified by PermissionId).

Role specifies the member's role. Valid values are:

Refer to UpdatePermissions for more information about how permissions work in general, how permissions relate to shared drive members, and how to manipulate multiple members at once. string sharedDriveId = "20983euijdsds"; // First, we'll add a new member to the shared drive. The two integer parameters signify: // * The role type. 2 is the "Writer" role, which provides read and write (but not organize) permissions. // * The permission type. 0 means this is a single user (versus a group). // The Id of the new permission we've created on the shared drive--which is what actually causes the user to // be a member of the shared drive--is returned. string permId = googledrive.AddSharedDriveMember(sharedDriveId, 2, 0, "fakeuser@example.com"); // At some point later, perhaps this user has abused their privileges and we wish to revoke their writer // permissions. We change their role to "Commenter", which provides reader and commenting permissions. googledrive.UpdateSharedDriveMember(sharedDriveId, permId, 1); // 1 is the "Commenter" role. // Or perhaps we wish to simply remove the user's shared drive membership completely. googledrive.RemoveSharedDriveMember(sharedDriveId, permId);

UploadFile Method (GoogleDrive Component)

Uploads, and optionally converts, a new file.

Syntax

String __fastcall UploadFile(String FileName, String MimeType);

Remarks

This method uploads a new file and returns the Id of the newly-created file resource.

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.

Usage

If MimeType is "", the file will be uploaded as-is and its MIME type will be automatically determined. The file can be converted to one of the Google formats by explicitly setting MimeType to one of the MIME types in the table below.

Before calling this method, always set ResourceCount to 0 to clear the stored resource data. Then, if you wish to set file metadata and/or assign parent Ids when the file is uploaded, set ResourceCount to 1 and set the desired properties. (Note that the name and MIME type passed to this method will take precedence.)

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

Finally, call this method to upload the file, along with any metadata that may be set.

Upload Notes

Google Drive 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 component uses the simple upload mechanism. googledrive.LocalFile = "../MyFile.zip"; googledrive.UploadFile("MyFile.zip", "");

Resumable

To enable resumable uploads set UseResumableUpload to true. This is recommended for large files. The component 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 component. 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 component 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 component is used, they should already be populated, and no special action should be needed). 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. GetUploadStatus may be used to check the status of a resumable upload. googledrive.LocalFile = "../MyFile.zip"; googledrive.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. googledrive.UploadFile("MyFile.zip", "");

ChangeList Event (GoogleDrive Component)

Fires once for each change when ListChanges is called.

Syntax

typedef struct {
  String ResourceId;
  String SharedDriveId;
  bool Removed;
  String Time;
  int ChangeType;
} TcsGoogleDriveChangeListEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveChangeListEvent)(System::TObject* Sender, TcsGoogleDriveChangeListEventParams *e);
__property TcsGoogleDriveChangeListEvent OnChangeList = { read=FOnChangeList, write=FOnChangeList };

Remarks

This event fires once for each change returned when ListChanges is called.

ResourceId is the Id of the file or folder to which the change applies.

SharedDriveId is the Id of the shared drive associated with the change.

Removed indicates whether the file or shared drive has been removed from the view of the change list. For example, if a file was permanently deleted or access to it was revoked, this would return true (it would still return false if the file was simply in the trash).

Time is a DateTime string representing the time of the change. This is a combined date-time value (formatted according to RFC 3339).

ChangeType indicates whether this is a file (0) or a shared drive (1) change.

Refer to ListChanges for more information.

EndTransfer Event (GoogleDrive Component)

This event fires when a document finishes transferring.

Syntax

typedef struct {
  int Direction;
} TcsGoogleDriveEndTransferEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveEndTransferEvent)(System::TObject* Sender, TcsGoogleDriveEndTransferEventParams *e);
__property TcsGoogleDriveEndTransferEvent OnEndTransfer = { read=FOnEndTransfer, write=FOnEndTransfer };

Remarks

The EndTransfer event is fired when the document text finishes transferring from the server to the local host.

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

Error Event (GoogleDrive Component)

Fired when information is available about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TcsGoogleDriveErrorEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveErrorEvent)(System::TObject* Sender, TcsGoogleDriveErrorEventParams *e);
__property TcsGoogleDriveErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

FragmentComplete Event (GoogleDrive Component)

Fires after each fragment of a resumable upload is completed.

Syntax

typedef struct {
  int FragmentNumber;
  int FragmentCount;
  bool Interrupt;
} TcsGoogleDriveFragmentCompleteEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveFragmentCompleteEvent)(System::TObject* Sender, TcsGoogleDriveFragmentCompleteEventParams *e);
__property TcsGoogleDriveFragmentCompleteEvent OnFragmentComplete = { read=FOnFragmentComplete, write=FOnFragmentComplete };

Remarks

When UseResumableUpload is true and UploadFile is called, this event will fire after each fragment is uploaded, providing an indication of overall upload progress.

FragmentNumber is the number of the current fragment that has completed. This value starts at 1.

FragmentCount is the total number of fragments that will be uploaded.

Interrupt can be set to true to interrupt the upload. The upload may be resumed later.

Header Event (GoogleDrive Component)

This event is fired every time a header line comes in.

Syntax

typedef struct {
  String Field;
  String Value;
} TcsGoogleDriveHeaderEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveHeaderEvent)(System::TObject* Sender, TcsGoogleDriveHeaderEventParams *e);
__property TcsGoogleDriveHeaderEvent OnHeader = { read=FOnHeader, write=FOnHeader };

Remarks

The Field parameter contains the name of the HTTP header (which is the same as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).

Log Event (GoogleDrive Component)

This event fires once for each log message.

Syntax

typedef struct {
  int LogLevel;
  String Message;
  String LogType;
} TcsGoogleDriveLogEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveLogEvent)(System::TObject* Sender, TcsGoogleDriveLogEventParams *e);
__property TcsGoogleDriveLogEvent OnLog = { read=FOnLog, write=FOnLog };

Remarks

This event fires once for each log message generated by the component. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

• "Info"
• "RequestHeaders"
• "ResponseHeaders"
• "RequestBody"
• "ResponseBody"
• "ProxyRequest"
• "ProxyResponse"
• "FirewallRequest"
• "FirewallResponse"

PermissionList Event (GoogleDrive Component)

This event fires once for each permission returned when listing permissions.

Syntax

typedef struct {
  String Id;
  int Role;
  int PermissionType;
  String Email;
  String Domain;
  bool AllowFileDiscovery;
} TcsGoogleDrivePermissionListEventParams;
typedef void __fastcall (__closure *TcsGoogleDrivePermissionListEvent)(System::TObject* Sender, TcsGoogleDrivePermissionListEventParams *e);
__property TcsGoogleDrivePermissionListEvent OnPermissionList = { read=FOnPermissionList, write=FOnPermissionList };

Remarks

When calling ListPermissions this event will fire once for each permission that is returned.

Id is the Id of the permission.

Role is the role of the permission. Possible values are:

PermissionType indicates the type of the permission. Possible values are:

Email holds the email address of the user or group that the permission applies to when Type is 0 or 1.

Domain holds the domain that the permission applies to when Type is 2.

AllowFileDiscovery signifies whether the permission allows the file to be discovered through search. It is only applicable when Type is 2 or 3.

Progress Event (GoogleDrive Component)

Fires during an upload or download to indicate transfer progress.

Syntax

typedef struct {
  int Direction;
  __int64 BytesTransferred;
  __int64 TotalBytes;
  int PercentDone;
} TcsGoogleDriveProgressEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveProgressEvent)(System::TObject* Sender, TcsGoogleDriveProgressEventParams *e);
__property TcsGoogleDriveProgressEvent OnProgress = { read=FOnProgress, write=FOnProgress };

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 component 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 component 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.

ResourceList Event (GoogleDrive Component)

Fires once for each resource returned when listing resources.

Syntax

typedef struct {
  String Id;
  String Name;
  String Extension;
  String Description;
  int ResourceType;
  String SharedDriveId;
  String CreatedTime;
  String ModifiedTime;
  __int64 Size;
  bool Trashed;
} TcsGoogleDriveResourceListEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveResourceListEvent)(System::TObject* Sender, TcsGoogleDriveResourceListEventParams *e);
__property TcsGoogleDriveResourceListEvent OnResourceList = { read=FOnResourceList, write=FOnResourceList };

Remarks

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

Id is the Id of the resource.

Name holds the resource's name.

Extension is the file extension.

Description holds a short description of the resource (if any).

ResourceType indicates whether the resource is a file or folder. Possible values are:

SharedDriveId is the Id of the shared drive which the resource is in, or empty string if it is not in a shared drive.

CreatedTime holds a DateTime string representing the creation date of the resource. This is a combined date-time value (formatted according to RFC 3339).

ModifiedTime holds a DateTime string representing the last modified date of the resource. This is a combined date-time value (formatted according to RFC 3339).

Size holds the size of the file in bytes. This is only applicable to files.

Trashed indicates whether the resource is in the trash.

SharedDriveList Event (GoogleDrive Component)

Fires once for each shared drive returned when listing shared drives.

Syntax

typedef struct {
  String Id;
  String Name;
  String CreatedTime;
  bool Hidden;
  int Capabilities;
  int Restrictions;
} TcsGoogleDriveSharedDriveListEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveSharedDriveListEvent)(System::TObject* Sender, TcsGoogleDriveSharedDriveListEventParams *e);
__property TcsGoogleDriveSharedDriveListEvent OnSharedDriveList = { read=FOnSharedDriveList, write=FOnSharedDriveList };

Remarks

This event fires once for each shared drive returned when ListSharedDrives is called.

Id is the Id of the shared drive.

Name holds the shared drive's name.

CreatedTime holds a DateTime string representing the creation date of the resource. This is a combined date-time value (formatted according to RFC 3339).

Hidden indicates whether the shared drive is hidden from default view (i.e., whether it is shown by default in the Google Drive UI).

Capabilities describes the effective capabilities that the current user has for the shared drive. The value is a bit field comprised of one or more of the following, OR'ed together:

Restrictions describes any restrictions that apply to the shared drive and/or its contents. The value is a bit field comprised of one or more of the following, OR'ed together:

SSLServerAuthentication Event (GoogleDrive Component)

Fired after the server presents its certificate to the client.

Syntax

typedef struct {
  String CertEncoded;
  DynamicArray<Byte> CertEncodedB;
  String CertSubject;
  String CertIssuer;
  String Status;
  bool Accept;
} TcsGoogleDriveSSLServerAuthenticationEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveSSLServerAuthenticationEvent)(System::TObject* Sender, TcsGoogleDriveSSLServerAuthenticationEventParams *e);
__property TcsGoogleDriveSSLServerAuthenticationEvent OnSSLServerAuthentication = { read=FOnSSLServerAuthentication, write=FOnSSLServerAuthentication };

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 (GoogleDrive Component)

Fired when secure connection progress messages are available.

Syntax

typedef struct {
  String Message;
} TcsGoogleDriveSSLStatusEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveSSLStatusEvent)(System::TObject* Sender, TcsGoogleDriveSSLStatusEventParams *e);
__property TcsGoogleDriveSSLStatusEvent OnSSLStatus = { read=FOnSSLStatus, write=FOnSSLStatus };

Remarks

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

StartTransfer Event (GoogleDrive Component)

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

Syntax

typedef struct {
  int Direction;
} TcsGoogleDriveStartTransferEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveStartTransferEvent)(System::TObject* Sender, TcsGoogleDriveStartTransferEventParams *e);
__property TcsGoogleDriveStartTransferEvent OnStartTransfer = { read=FOnStartTransfer, write=FOnStartTransfer };

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 (GoogleDrive Component)

This event is fired while a document transfers (delivers document).

Syntax

typedef struct {
  int Direction;
  __int64 BytesTransferred;
  int PercentDone;
  String Text;
  DynamicArray<Byte> TextB;
} TcsGoogleDriveTransferEventParams;
typedef void __fastcall (__closure *TcsGoogleDriveTransferEvent)(System::TObject* Sender, TcsGoogleDriveTransferEventParams *e);
__property TcsGoogleDriveTransferEvent OnTransfer = { read=FOnTransfer, write=FOnTransfer };

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.
