DigitalOcean Control
Properties Methods Events Config Settings Errors
The DigitalOcean control provides an easy way to interface with DigitalOcean's Spaces service.
Syntax
DigitalOcean
Remarks
The DigitalOcean Spaces service has an API that is compatible with that of Amazon S3, allowing you to store arbitrary data using the same bucket-and-object paradigm that S3 uses.
To use the DigitalOcean control, you will first need to sign up for the DigitalOcean Spaces service and obtain an AccessKey and a SecretKey. Then you can start creating buckets in your account using CreateBucket. The buckets are place holders for your objects allowing you to access them by http URLs. You can then add objects to any of your buckets using CreateObject.
There are other methods such as ListBuckets, ListObjects, GetObject, GetLink, DeleteObject etc. that further enable you to manage your data store.

The PrefixList event will fire once for each common prefix returned. If the StorePrefixList configuration setting is enabled, the control will also populate the PrefixCount and Prefix[i] configuration settings
Object Hierarchy Traversal
By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:

- MyCompany/Department1/
- MyCompany/Department2/
- MyCompany/Department2/EmployeeA
- MyCompany/Department2/EmployeeB
With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:
ObjectPrefix Value | ObjectDelimiter Value | Objects Returned | Prefixes Returned |
(empty) | / | (none) | MyCompany/ |

This specifies the SSL/TLS implementation to use.
Syntax
digitaloceancontrol.SSLProvider[=integer]
Possible Values
sslpAutomatic(0), sslpPlatform(1), sslpInternal(2)
Default Value
0
Remarks
This property specifies the SSL/TLS implementation to use. In most cases the default value of 0 (Automatic) is recommended and should not be changed. When set to 0 (Automatic) the control will select whether to use the platform implementation or the internal implementation depending on the operating system as well as the TLS version being used.
Possible values are:
0 (sslpAutomatic - default) | Automatically selects the appropriate implementation. |

Data Type
Integer
SSLServerCertEncoded Property (DigitalOcean Control)
This is the certificate (PEM/Base64 encoded).
Syntax
digitaloceancontrol.SSLServerCertEncoded
Default Value
""
Remarks
This is the certificate (PEM/Base64 encoded). This property is used to assign a specific certificate. The SSLServerCertStore and SSLServerCertSubject properties also may be used to specify a certificate.
When SSLServerCertEncoded is set, a search is initiated in the current SSLServerCertStore for the private key of the certificate. If the key is found, SSLServerCertSubject is updated to reflect the full subject of the selected certificate; otherwise, SSLServerCertSubject is set to an empty string.
To read or write binary data to the property, a Variant (Byte Array) version is provided in .SSLServerCertEncodedB.
This property is read-only and not available at design time.
Data Type
Binary String
StartByte Property (DigitalOcean Control)
The byte offset from which to resume the upload or download.
Syntax
digitaloceancontrol.StartByte[=long64]
Default Value
0
Remarks
This property specifies the byte offset from which to resume an automatic multipart upload initiated by CreateObject, or a download initiated by GetObject. Refer to those methods' documentation for more information about resuming uploads and downloads.
This property is not available at design time.
Data Type
Long64
Timeout Property (DigitalOcean Control)
A timeout for the control.
Syntax
digitaloceancontrol.Timeout[=integer]
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 control will wait for the operation to complete before returning control.
The control 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 control fails with an error.
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.
Data Type
Integer
UseVirtualHosting Property (DigitalOcean Control)
Determines which style request to use.
Syntax
digitaloceancontrol.UseVirtualHosting[=boolean]
Default Value
True
Remarks
If set to (default), buckets will be referenced in the request using the hosted-style request: http://yourbucket.nyc3.digitaloceanspaces.com/yourobject. If , the control will use the path-style request: http://nyc3.digitaloceanspaces.com/yourbucket/yourobject.
NOTE: When set to , there are more limitations when choosing a bucket name due to DNS server naming restrictions. DigitalOcean follows Amazon's naming restrictions, so refer to Amazon's S3 documentation for more information.
This property is not available at design time.
Data Type
Boolean
VersionId Property (DigitalOcean Control)
The object version to make requests against.
Syntax
digitaloceancontrol.VersionId[=string]
Default Value
""
Remarks
This property can be set to the Id of a specific object version before calling the following methods in order to make requests against the specified object version instead of the base object; refer to each one's documentation for more information:
- CopyObject (to copy from a specific object version)
- DeleteObject
- GetLink (to build a link for a specific object version)
- GetObject
- GetObjectInfo
- SendCustomRequest
- UpdateObjectACL
Refer to Amazon's Versioning documentation for more information about versioning.
This property is not available at design time.
Data Type
String
VersioningEnabled Property (DigitalOcean Control)
Controls whether versioning is enabled for the currently selected bucket.
Syntax
digitaloceancontrol.VersioningEnabled[=boolean]
Default Value
False
Remarks
This property can be used to query and control whether the bucket currently selected by Bucket has versioning enabled.
Note that if Bucket is empty, or refers to a bucket that does not exist, this property will always return when queried, and any attempts to set it will fail.
Refer to Amazon's Versioning documentation for more information about versioning.
This property is not available at design time.
Data Type
Boolean
VersionMarker Property (DigitalOcean Control)
A marker indicating what page of object versions to return next.
Syntax
digitaloceancontrol.VersionMarker[=string]

This property will be populated when ListVersions is called if the results are paged and there are more pages. To list all object versions, continue to call ListVersions until this property returns empty string.
Refer to ListVersions for more information.
This property is not available at design time.
Data Type
String
AbortMultipartUpload Method (DigitalOcean Control)
Aborts a multipart upload.
Syntax
digitaloceancontrol.AbortMultipartUpload ObjectName, UploadId
Remarks
This method aborts the multipart upload of the object named ObjectName specified by UploadId.
When this method is called, all parts that have been uploaded for the multipart upload are deleted from the server. (Note that if any part uploads are currently in progress, it may be necessary to call this method again after they complete.)
If this method is called successfully, the specified UploadId will no longer be valid.
AddMetadata Method (DigitalOcean Control)
Adds a metadata item to the Metadata properties.
Syntax
digitaloceancontrol.AddMetadata Name, Value
Remarks
This method adds a metadata item to the Metadata* properties. Name specifies the name of the item, and Value specifies the value of the item. Keep in mind that the server stores metadata names in lowercase.
If Name begins with a service-specific metadata (e.g., x-amz-meta-, x-goog-meta-, etc.), it will be stripped off. The control will take care of prepending it when sending metadata to the server.
AddQueryParam Method (DigitalOcean Control)
Adds a query parameter to the QueryParams properties.
Syntax
digitaloceancontrol.AddQueryParam Name, Value
Remarks
This method is used to add a query parameter to the QueryaParam* 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 control automatically. Consult the service documentation for details on the available parameters.
BucketExists Method (DigitalOcean Control)
Checks whether the bucket exists.
Syntax
digitaloceancontrol.BucketExists
Remarks
This method checks whether the bucket specified by Bucket exists, returning if so or if not.
CheckVersioningEnabled Method (DigitalOcean Control)
Checks whether versioning is enabled for the currently selected bucket.
Syntax
digitaloceancontrol.CheckVersioningEnabled
Remarks
This method can be used to check whether the bucket currently selected by Bucket has versioning enabled.
Note that if Bucket is empty, or refers to a bucket that does not exist, this method will always return when queried.
Refer to Amazon's Versioning documentation for more information about versioning.
CompleteMultipartUpload Method (DigitalOcean Control)
Completes a multipart upload by assembling previously uploaded parts.
Syntax
digitaloceancontrol.CompleteMultipartUpload ObjectName, UploadId
Remarks
This method completes the multipart upload specified by UploadId. The server will assemble all of the parts that have been uploaded into an object named ObjectName.
Note that this method automatically calls ListParts internally to obtain the information needed to complete the multipart upload. This process does not alter the Parts* properties, nor does it cause the PartList event to fire.
Config Method (DigitalOcean Control)
Sets or retrieves a configuration setting.
Syntax
digitaloceancontrol.Config ConfigurationString
Remarks
Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, 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.
CopyObject Method (DigitalOcean Control)
Copies an object.
Syntax
digitaloceancontrol.CopyObject SrcObjectName, DestBucket, DestObjectName
Remarks
This method copies the object specified by SrcObjectName (in the bucket currently selected by Bucket) to the object specified by DestObjectName in DestBucket. If DestBucket is empty, the bucket specified by Bucket is used as the destination bucket.
If the VersionId property is non-empty, the specified version of the source object will be used as the copy source. In this case, DestObjectName may be the same as SrcObjectName to "promote" the version, copying its contents back to the base object.
If there are any metadata items present in the Metadata* properties, they will set on the destination object; otherwise, the server will copy any metadata items present on the source object to the destination object.
Notes:
- Objects may only be copied to buckets that exist within the same region.
- Objects larger than 5GB cannot be copied using this method. To copy such objects, start a new multipart upload for the destination object using StartMultipartUpload, and then use the CopyPart method to create parts for said multipart upload using the source object's data.
CopyPart Method (DigitalOcean Control)
Copies the specified object as a part of a multipart upload.
Syntax
digitaloceancontrol.CopyPart SrcObjectName, DestBucket, DestObjectName, DestPartNumber, DestUploadId
Remarks
This method copies data from the object specified by SrcObjectName (in the bucket currently selected by Bucket) to a new multipart upload part for DestObjectName in DestBucket.
The DestPartNumber and DestUploadId parameters should be used in the same manner as the UploadPart method's PartNumber and UploadId parameters.
To copy a specific range of bytes from the source object, set the CopyPartRange configuration setting before calling this method.
CreateBucket Method (DigitalOcean Control)
Creates a new bucket.
Syntax
digitaloceancontrol.CreateBucket
Remarks
This method creates a new bucket using the name specified by the Bucket property. The bucket is created in the region specified by the Region property.
CreateObject Method (DigitalOcean Control)
Creates a new object in the currently selected bucket.
Syntax
digitaloceancontrol.CreateObject ObjectName
Remarks
This method creates a new object named Object in the bucket currently selected by Bucket. If there are any metadata items present in the Metadata* properties, they will included in the creation request.
If LocalFile is set the file will be uploaded from the specified path. If LocalFile is not set the data in ObjectData will be used.
To encrypt the file before uploading it, set EncryptionAlgorithm and EncryptionPassword.
This method can automatically handle the multipart upload of objects (See Below). If it is desired to manually take control of the multipart upload process see StartMultipartUpload.
Automatic Multipart Uploads
If more than SimpleUploadLimit bytes of data are provided, the control will automatically perform a multipart upload by splitting the data up into parts (sized according to the FragmentSize configuration setting) and uploading them individually. To accomplish this, the control automatically makes calls to StartMultipartUpload, UploadPart, and CompleteMultipartUpload internally; tracks upload state information using the ResumableUploadState configuration setting; and tracks how much data has been uploaded using the StartByte property. The FragmentComplete event will fire after each part is uploaded.
If, during an automatic multipart upload, any individual request fails, the upload can be resumed be calling this method again with the same parameters, so long as ResumableUploadState and StartByte contain the same values as they did when the upload was interrupted.
When an automatic multipart upload completes successfully, ResumableUploadState is cleared and StartByte is reset to 0.
DeleteBucket Method (DigitalOcean Control)
Deletes a bucket.
Syntax
digitaloceancontrol.DeleteBucket
Remarks
This method deletes the bucket currently selected by Bucket. Note that bucket names share a global namespace, and it may not be possible to recreate a deleted bucket if its name has been taken by another user in the meantime.
DeleteObject Method (DigitalOcean Control)
Deletes an object.
Syntax
digitaloceancontrol.DeleteObject ObjectName
Remarks
This method deletes the object specified by ObjectName in the bucket currently selected by Bucket.
If the VersionId property is non-empty, this method deletes the specified version of the object instead.
Deleting Versioned Objects
If a bucket has versioning enabled (i.e., VersioningEnabled returns when queried), and this method is called on an object rather than a specific object version, then instead of actually deleting any data, the server will simply create a special object version called a delete marker.If an object's latest version is a delete marker, then the server treats the object as if it didn't exist (i.e., it doesn't appear when listing objects, cannot be downloaded, etc.). However, all of the previous versions of the object (including one that existed just before the delete marker was created) still exist; they can be listed using ListVersions, and explicitly interacted with by setting VersionId and calling an appropriate method.
To permanently delete objects in a versioning-enabled bucket, each version of the object must be explicitly deleted by setting VersionId before calling this method. This includes any delete marker versions, which can be deleted like any other version.
Refer to Amazon's Deleting Object Versions, Working with Delete Markers, and Removing Delete Markers articles for more information.
DisableVersioning Method (DigitalOcean Control)
Disables versioning for the currently selected bucket.
Syntax
digitaloceancontrol.DisableVersioning
Remarks
This method can be used to disable versioning for the bucket currently selected by Bucket.
Refer to Amazon's Versioning documentation for more information about versioning.
DoEvents Method (DigitalOcean Control)
Processes events from the internal message queue.
Syntax
digitaloceancontrol.DoEvents
Remarks
When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.
EnableVersioning Method (DigitalOcean Control)
Enables versioning for the currently selected bucket.
Syntax
digitaloceancontrol.EnableVersioning
Remarks
This method can be used to enable versioning for the bucket currently selected by Bucket.
Refer to Amazon's Versioning documentation for more information about versioning.
GetBucketLocation Method (DigitalOcean Control)
Gets a bucket's location.
Syntax
digitaloceancontrol.GetBucketLocation
Remarks
This method retrieves and returns the location (i.e., region) of the bucket currently selected by Bucket.
GetLink Method (DigitalOcean Control)
Creates a link that provides access to an object for a specified amount of time.
Syntax
digitaloceancontrol.GetLink ObjectName, Expires
Remarks
This method creates and returns a pre-authenticated link that provides access to the object specified by ObjectName in the bucket currently selected by Bucket. If the VersionId property is non-empty, a link is created for the specified version of the object.
The Expires parameter specifies how many seconds the link should be valid for. The maximum validity period is seven days.
Note that this method is an offline method that simply generates a pre-signed URL; no communication with the server takes place.
GetObject Method (DigitalOcean Control)
Downloads an object.
Syntax
digitaloceancontrol.GetObject ObjectName
Remarks
This methods downloads the object specified by ObjectName in the bucket currently selected by Bucket. If the VersionId property is non-empty, the specified version of the object is downloaded instead. The Range property can be used to download a specific range of bytes from the object.
If LocalFile is set, the object data will be saved to the specified location; otherwise, the object data will be held by ObjectData.
To download and decrypt an encrypted object, set EncryptionAlgorithm and EncryptionPassword before calling this method.
Download Notes
In the simplest use-case, downloading an object looks like this:
s3.LocalFile = "../MyData.zip";
s3.GetObject(s3.Objects[0].Name);
Resuming Downloads
The control 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 = "../MyData.zip";
s3.LocalFile = downloadFile;
s3.GetObject(s3.Objects[0].Name);
//The transfer is interrupted and GetObject() above fails. Later, resume the download:
//Get the size of the partially downloaded file
s3.StartByte = new FileInfo(downloadFile).Length;
s3.GetObject(s3.Objects[0].Name);
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 control 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.
s3.LocalFile = "../MyData.zip";
s3.EncryptionPassword = "password";
s3.GetObject(s3.Objects[0].Name);
//The transfer is interrupted and GetObject() above fails. Later, resume the download:
//Get the size of the partially downloaded temp file
s3.StartByte = new FileInfo(s3.Config("DownloadTempFile")).Length;
s3.GetObject(s3.Objects[0].Name);
GetObjectInfo Method (DigitalOcean Control)
Gets an object's information and metadata.
Syntax
digitaloceancontrol.GetObjectInfo ObjectName
Remarks
This method gets information and metadata for the object specified by Object in the bucket currently selected by Bucket. If the VersionId property is non-empty, information and metadata for the specified version of the object is retrieved instead.
Calling this method will fire the ObjectList and MetadataList events, and will re-populate the Objects* and Metadata* properties.
Interrupt Method (DigitalOcean Control)
Interrupt the current method.
Syntax
digitaloceancontrol.Interrupt
Remarks
If there is no method in progress, Interrupt simply returns, doing nothing.
ListBuckets Method (DigitalOcean Control)
Lists all buckets in the account.
Syntax
digitaloceancontrol.ListBuckets
Remarks
This method lists all buckets in the account.
Calling this method will fire the BucketList event once for each bucket, and will also populate the Buckets* properties.
ListMultipartUploads Method (DigitalOcean Control)
Lists the current multipart uploads.
Syntax
digitaloceancontrol.ListMultipartUploads
Remarks
This method lists the current multipart uploads in the bucket currently selected by Bucket.
Before calling this method, the ObjectPrefix property may be set in order to restrict the results to only the multipart uploads whose names begin with a given string. The ObjectDelimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.
Calling this method will fire the ObjectList event once for each multipart upload, and will also populate the Objects* properties.
If there are still more multipart uploads available to list when this method returns, the ObjectMarker property will be populated. Continue to call this method until ObjectMarker is empty to accumulate all pages of results in the Objects* properties.
ListObjects Method (DigitalOcean Control)
Lists the objects in a bucket.
Syntax
digitaloceancontrol.ListObjects
Remarks
This method lists the objects in the bucket currently selected by Bucket.
Before calling this method, the ObjectPrefix property may be set in order to restrict the results to only the objects whose names begin with a given string. The ObjectDelimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.
Calling this method will fire the ObjectList event once for each object, and will also populate the Objects* properties. It may also fire the PrefixList event, and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.
If there are still more objects available to list when this method returns, the ObjectMarker property will be populated. Continue to call this method until ObjectMarker is empty to accumulate all pages of results in the Objects* properties.
Object Hierarchy Traversal
By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:
- MyCompany/
- MyCompany/Department1/
- MyCompany/Department2/
- MyCompany/Department2/EmployeeA
- MyCompany/Department2/EmployeeB
With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:
ObjectPrefix Value | ObjectDelimiter Value | Objects Returned | Prefixes Returned |
(empty) | / | (none) | MyCompany/ |
MyCompany/ | / | MyCompany/ | MyCompany/Department1/
MyCompany/Department2/ |
MyCompany/Department2/ | / | MyCompany/Department2/
MyCompany/Department2/EmployeeA MyCompany/Department2/EmployeeB | (none) |
ListParts Method (DigitalOcean Control)
Lists the parts in a multipart upload.
Syntax
digitaloceancontrol.ListParts ObjectName, UploadId
Remarks
This method lists the parts in the multipart upload of ObjectName specified by UploadId. The MaxParts configuration setting may be used to limit the number of results returned.
Calling this method will fire the PartList event once for each part, and will also populate the Parts* properties.
If there are still more parts available to list when this method returns, the PartMarker property will be populated. Continue to call this method until PartMarker is empty to accumulate all pages of results in the Parts* properties.
Note that this method does not need to be called before attempting to complete a multipart upload with CompleteMultipartUpload; the control will automatically collect the necessary information internally. Refer to CompleteMultipartUpload for more information.
ListVersions Method (DigitalOcean Control)
Lists the object versions in a bucket.
Syntax
digitaloceancontrol.ListVersions
Remarks
This method lists the object versions in the bucket currently selected by Bucket.
Before calling this method, the ObjectPrefix property may be set in order to restrict the results to only the object versions whose names begin with a given string. The ObjectDelimiter property can also be used to further tune the results returned. The MaxObjects configuration setting may be used to limit the number of results returned.
Calling this method will fire the ObjectList event once for each object version, and will also populate the Objects* properties. It may also fire the PrefixList event, and populate the PrefixCount and Prefix[i] configuration settings, depending on how the properties discussed above are set.
If there are still more object versions available to list when this method returns, the VersionMarker property will be populated. Continue to call this method until VersionMarker is empty to accumulate all pages of results in the Objects* properties.
Object Hierarchy Traversal
By using the ObjectDelimiter and ObjectPrefix properties in tandem, applications can effectively "traverse" a virtual hierarchy of objects (or object versions) as if it were a filesystem. For example, assume that objects with the following names exist within a bucket:
- MyCompany/
- MyCompany/Department1/
- MyCompany/Department2/
- MyCompany/Department2/EmployeeA
- MyCompany/Department2/EmployeeB
With ObjectDelimiter set to /, we can set ObjectPrefix to successively "deeper" values before calling ListObjects or ListVersions for the following effect:
ObjectPrefix Value | ObjectDelimiter Value | Objects Returned | Prefixes Returned |
(empty) | / | (none) | MyCompany/ |
MyCompany/ | / | MyCompany/ | MyCompany/Department1/
MyCompany/Department2/ |
MyCompany/Department2/ | / | MyCompany/Department2/
MyCompany/Department2/EmployeeA MyCompany/Department2/EmployeeB | (none) |

ResetHeaders Method (DigitalOcean Control)
Resets all HTTP headers, cookies, and LocalFile.
Syntax
digitaloceancontrol.ResetHeaders
Remarks
Resets all the HTTP headers as well as LocalFile to "" (empty string), and clears the Metadata* and QueryParam* properties.
Call this method before creating a new request, so that headers and query parameters from the previous request are not carried over to the next one.
SendCustomRequest Method (DigitalOcean Control)
Sends a custom request to the server.
Syntax
digitaloceancontrol.SendCustomRequest HttpMethod, ObjectName, RequestBody
Remarks
This method can be used to send arbitrary requests to the server.

The ObjectName and RequestBody parameters may be empty if not needed.
Usage
When this method is called, the control does the following:
- Builds a request URL, including query parameters, based on the following:
- UseSSL, Region, and UseVirtualHosting for the base URL.
- Alternatively, if a custom URL has been specified using the URL configuration setting, it is used directly, and these properties are ignored.
- Bucket (if non-empty)
- ObjectName (if non-empty)
- VersionId (if both it and ObjectName are non-empty)
- QueryParam*
- UseSSL, Region, and UseVirtualHosting for the base URL.
- Adds request headers from:
- Signs the request (unless the SignCustomRequest configuration setting is disabled).
- Sends the request, including RequestBody if non-empty.
- Stores the response headers in the ParsedHeader* properties; and the response body in the specified LocalFile, or ObjectData (using the same logic as GetObject).
If the response body is XML data, the XPath, XText, and other X* configuration settings can then be used to navigate and extract information from it.
StartMultipartUpload Method (DigitalOcean Control)
Starts a new manual multipart upload.
Syntax
digitaloceancontrol.StartMultipartUpload ObjectName
Remarks
This method starts a new "manual" multipart upload for an object named ObjectName, in the bucket currently selected by Bucket, and returns the upload Id that the server associates with it. For an "automatic" multipart upload see the CreateObject method. This upload Id can then be used to call the following methods:
If there are any metadata items present in the Metadata* properties, they will be included in the creation request, and will be applied to the final object after the multipart upload is completed with CompleteMultipartUpload.
Multipart uploads never expire, they must be explicitly completed or aborted using CompleteMultipartUpload or AbortMultipartUpload. The ListMultipartUploads method can be used to retrieve a list of current multipart uploads.
UpdateBucketACL Method (DigitalOcean Control)
Updates a bucket's canned access policy.
Syntax
digitaloceancontrol.UpdateBucketACL
Remarks
This method updates the canned access policy of the bucket selected by Bucket to the value specified by AccessPolicy
UpdateObjectACL Method (DigitalOcean Control)
Updates an object's canned access policy.
Syntax
digitaloceancontrol.UpdateObjectACL ObjectName
Remarks
This method updates the caned access policy of the objects specified by ObjectName, in the bucket currently selected by Bucket, to the value specified by AccessPolicy.
If the VersionId property is non-empty, the canned access policy of the specified version of the object is updated instead.
UploadPart Method (DigitalOcean Control)
Uploads a multipart upload part.
Syntax
digitaloceancontrol.UploadPart ObjectName, PartNumber, UploadId
Remarks
This method uploads a part for the multipart upload of the object named ObjectName specified by UploadId.
PartNumber specifies the part's number; it must be a value in the range 1 to 10000, inclusive. If a part with the given number already exists in the specified multipart upload, it is replaced with the newly-uploaded part.
The data to upload is taken from either LocalFile or ObjectData (whichever data is found in first, when checked in that order). Each part must be at least 5MB in size, except for the last part in the overall multipart upload, which can be any non-zero size.
If the IncludePartMD5 configuration setting is , the control will include an MD5 digest of its data when sending it to the server. The server will then verify that the data was received without corruption.
BucketList Event (DigitalOcean Control)
Fires once for each bucket returned when listing buckets.
Syntax
Sub digitaloceancontrol_BucketList(BucketName As String, CreationDate As String, OwnerId As String, OwnerName As String)
Remarks
This event fires once for each bucket returned when ListBuckets is called.
BucketName reflects the name of the bucket.
CreationDate reflects the bucket's creation date.
OwnerId and OwnerName reflect the Id and display name of the bucket's owner, respectively.
EndTransfer Event (DigitalOcean Control)
This event fires when a document finishes transferring.
Syntax
Sub digitaloceancontrol_EndTransfer(Direction As Integer)
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 (DigitalOcean Control)
Fired when information is available about errors during data delivery.
Syntax
Sub digitaloceancontrol_Error(ErrorCode As Integer, Description As String)
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.
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 (DigitalOcean Control)
Fires after each part in an automatic multipart upload is complete.
Syntax
Sub digitaloceancontrol_FragmentComplete(FragmentNumber As Integer, FragmentCount As Integer, Interrupt As Boolean)
Remarks
If, when CreateObject is called, more than SimpleUploadLimit bytes of upload data are present, the control will automatically split the upload data up into parts and perform a multipart upload. During the overall upload process, this event will fire after each part is uploaded, providing an indication of overall upload progress.
FragmentNumber is the number of the current part that has completed. This value starts at 1.
FragmentCount is the total number of parts that will be uploaded.
Interrupt can be set to to interrupt the upload. The upload may be resumed later.
Refer to CreateObject for more information.
Header Event (DigitalOcean Control)
This event is fired every time a header line comes in.
Syntax
Sub digitaloceancontrol_Header(Field As String, Value As String)
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 (DigitalOcean Control)
This event fires once for each log message.
Syntax
Sub digitaloceancontrol_Log(LogLevel As Integer, Message As String, LogType As String)
Remarks
This event fires once for each log message generated by the control. The verbosity is controlled by the LogLevel setting.
LogLevel indicates the level of message. Possible values are as follows:
0 (None) | No events are logged. |
1 (Info - default) | Informational events are logged. |
2 (Verbose) | Detailed data are logged. |
3 (Debug) | Debug data are logged. |
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"
MetadataList Event (DigitalOcean Control)
Fires once for each metadata item returned when object information and metadata is retrieved.
Syntax
Sub digitaloceancontrol_MetadataList(Name As String, Value As String)
Remarks
This event fires once for each metadata item returned when GetObjectInfo is called.
Name is the name of the metadata item, without the service-specific prefix (e.g., x-amz-meta-, x-goog-meta-, etc.). Keep in mind that the server stores metadata names in lowercase.
Value is the metadata item's value.
ObjectList Event (DigitalOcean Control)
Fires once for each object, object version, or multipart upload returned when listing such items.
Syntax
Sub digitaloceancontrol_ObjectList(BucketName As String, ObjectName As String, LastModified As String, Size As Long64, ETag As String, OwnerId As String, OwnerName As String, UploadId As String, VersionId As String, LatestVersion As Boolean, Deleted As Boolean)
Remarks
This event fires once for each object, object version, or multipart upload returned when GetObjectInfo, ListObjects, ListVersions, or ListMultipartUploads is called.
BucketName reflects the name of the bucket that the object is in.
ObjectName reflects the name of the object.
LastModified reflects the last modified time of the object. Not applicable when ListMultipartUploads is called.
Size reflects the size, in bytes, of the object. Not applicable when ListMultipartUploads is called.
ETag reflects the object's ETag. Not applicable when ListMultipartUploads is called.
OwnerId and OwnerName reflect the Id and display name of the object's owner, respectively. Not applicable when GetObjectInfo is called.
UploadId reflects the Id of the multipart upload. Only applicable when ListMultipartUploads is called.
VersionId reflects the Id of the object version (note that the string null is a valid version Id). Only applicable when ListVersions is called, or when GetObjectInfo is called while VersionId is non-empty; empty in all other cases.
LatestVersion indicates whether this is the latest object version. Only applicable when ListVersions is called; in all other cases.
Deleted indicates whether this object version is a delete marker (refer to DeleteObject for more information). Only applicable when ListVersions is called, or when GetObjectInfo is called while VersionId is non-empty; in all other cases.
PartList Event (DigitalOcean Control)
Fires once for every part returned when listing a multipart upload's parts.
Syntax
Sub digitaloceancontrol_PartList(PartNumber As Integer, ObjectName As String, LastModified As String, Size As Long64, ETag As String, OwnerId As String, OwnerName As String)
Remarks
This event fires once for each multipart upload part returned when ListParts is called.
PartNumber reflects the part's number.
ObjectName reflects the name of the object the multipart upload is for.
LastModified reflects the last modified time of the part.
Size reflects the size, in bytes, of the part.
ETag reflects the part's ETag of the part.
OwnerId and OwnerName reflect the Id and display name of the part's owner, respectively.
PrefixList Event (DigitalOcean Control)
Fires once for each common prefix returned when listing objects.
Syntax
Sub digitaloceancontrol_PrefixList(BucketName As String, Prefix As String)
Remarks
This event fires once for each common prefix returned when ListObjects or ListVersions is called when ObjectDelimiter is non-empty. Refer to ObjectDelimiter for more information.
BucketName reflects the name of the bucket that the prefix is in.
Prefix is the common prefix.
Progress Event (DigitalOcean Control)
Fires during an upload or download to indicate transfer progress.
Syntax
Sub digitaloceancontrol_Progress(Direction As Integer, BytesTransferred As Long64, TotalBytes As Long64, PercentDone As Integer)
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 control 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 control 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.
SSLServerAuthentication Event (DigitalOcean Control)
Fired after the server presents its certificate to the client.
Syntax
Sub digitaloceancontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)
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 (DigitalOcean Control)
Fired when secure connection progress messages are available.
Syntax
Sub digitaloceancontrol_SSLStatus(Message As String)
Remarks
The event is fired for informational and logging purposes only. This event tracks the progress of the connection.
StartTransfer Event (DigitalOcean Control)
This event fires when a document starts transferring (after the headers).
Syntax
Sub digitaloceancontrol_StartTransfer(Direction As Integer)
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 (DigitalOcean Control)
This event is fired while a document transfers (delivers document).
Syntax
Sub digitaloceancontrol_Transfer(Direction As Integer, BytesTransferred As Long64, PercentDone As Integer, Text As String)
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.
Config Settings (DigitalOcean Control)
The control accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.DigitalOcean Config Settings
By default, this setting is enabled, allowing all pages of results to be accumulated in the appropriate collection properties.
The control supports key-based credential profiles; i.e., those which include the aws_access_key_id, aws_secret_access_key, and (optionally) aws_session_token elements. Role-based profiles are not supported at this time.
In addition to the authentication-related elements mentioned above, the control also supports the region element, if it is present in the specified profile.
The control searches for the specified profile's information in the credentials and config files. The AWSProfileDir setting can be used to configure the directory where the control looks for these files. If the aforementioned files do not exist, or the specified profile cannot be found or is missing information, an error will occur.
Note: If the profile specified using this setting includes credential information, the UseEC2RoleCredentials setting will be ignored (if it is enabled).
By default, this setting is empty, which will cause the control to check the default location used by the AWS CLI: an .aws directory in the current user's home directory; i.e., %UserProfile%\.aws (Windows) or ~/.aws (Linux/macOS).
When downloading encrypted data with LocalFile set, the control will automatically create a temporary file at TempPath to hold the encrypted file contents. When the download is complete, the data is decrypted to LocalFile.
If the download is interrupted, the specified file will hold the partially downloaded encrypted file contents. Before resuming the download, this setting must be set to a valid file containing the partially encrypted file contents. See DownloadFile for details.
This setting accepts a hex encoded value.
This setting accepts a hex encoded value.
- 0 (default) - PBKDF1
- 1 - PBKDF2
- Bucket names can contain lowercase letters, numbers, periods, underscores, and dashes.
- Bucket names must start with a number or letter.
- Bucket names must be between 3 and 63 characters long.
- Bucket names should not end with a dash.
- Bucket names cannot contain two adjacent periods.
- Bucket names cannot contain dashes next to periods.
- Bucket names must not be formatted as an IP address (eg: 192.168.5.4).
The ETag is used to determine if the object has changed since the last operation on the file. Set the IfMatch config to the ETag to ensure a new version of the object does not already exist on the server.
Valid values are 5242880 (5MB) to 2147483647 (2GB). The default is 26214400 (25MB). Note that applications may need to increase this setting's value in order to upload very large objects; Amazon only allows 10000 parts to be uploaded for any given multipart upload.
If the amount of upload data provided when creating an object is less than SimpleUploadLimit bytes, it will be uploaded directly, so this setting will not apply.
The default value is . Note that this setting is only applicable if the SignCustomRequest setting is ; it is ignored otherwise.
The default value is .
The default value is .
If this setting is -1 (default), the server's default (1000) is used. Acceptable values are 1 to 1000 (inclusive).
If this setting is -1 (default), the server's default (1000) is used. Acceptable values are 1 to 1000 (inclusive).
Valid values for i are from 0 to (PrefixCount - 1).
This setting is always -1 when StorePrefixList is disabled.
If this setting is enabled (default), then when a transfer is interrupted and later resumed, the values reported by the Progress event will account for the data that was successfully transferred before the interruption.
If this setting is disabled, then the control will treat resumed transfers as "new" transfers, and the values reported by the Progress event will start at 0 rather than from the number of bytes already transferred.
Refer to the Progress event for more information.
The default value, 1, will cause the Progress event to fire each time the event's PercentDone parameter value increases by one percent. Setting this setting to 0 will cause the Progress event to fire every time data is transferred.
Note that the Progress event will always fire once at the beginning and end of a transfer, regardless of this setting's value. Also, if PercentDone cannot be calculated for a particular transfer (e.g., for downloads that use chunked transfer encoding), then the control will behave as if this setting were 0 for the duration of the transfer.
Refer to CreateObject for more information.
This value must be provided as a traditional Unix timestamp. A Unix timestamp is the number of seconds since the Unix Epoch (00:00:00 January 1, 1970 UTC). An example value for the timestamp would be 1236626334.
Valid values are -1 to 5368709120 (5GB), inclusive. The default is 104857600 (100MB). If this setting is set to 0, the control will always perform a multipart upload when creating an object; if it is set to -1, the control will never perform a multipart upload.
The default value for this setting is .
By default, this setting is disabled.
In order for the control to be able to auto-obtain authentication credentials, the EC2 instance must have an "instance profile" with an appropriate IAM role attached to it. Refer to the "Using an IAM Role to Grant Permissions to Applications Running on Amazon EC2 Instances" page in the Amazon IAM documentation for more information.
By default, this setting is . When set to the control will do the following before each request:
- Make a request against the EC2 instance to get the name of the role attached to it.
- Make a request against the metadata service to initiate a session. The request returns a token that must be included in subsequent requests.
- Parse the response, automatically populating the AccessKey and SecretKey properties and the SessionToken configuration setting.
- Execute the original request using the temporary security credentials that were acquired.
Note: This setting is ignored if the AWSProfile setting is set to a profile that includes credential information.
The current element is specified via the XPath configuration setting. This configuration setting is read-only.
The current element is specified via the XPath configuration setting. This configuration setting is read-only.
The current element is specified via the XPath configuration setting. This configuration setting is read-only.
The current element is specified via the XPath configuration setting. This configuration setting is read-only.
The current element is specified via the XPath configuration setting. This configuration setting is read-only.
When XPath is set to a valid path, XElement points to the name of the element, with XText, XParent, XSubTree, XChildCount, XChildName[i], and XChildXText[i] providing other properties of the element.
XPath Syntax
XPath syntax is available for both XML and JSON documents. An XPath is a series of one or more element accessors separated by the / character, for example: /A/B/C/D. An XPath can be absolute (i.e., it starts with /), or it can be relative to the current XPath location.
The following are possible values for an element accessor, which operates relative to the current location specified by the XPath accessors which proceed it in the overall XPath string:
Accessor | Description |
name | The first element with a particular name. Can be *. |
[i] | The i-th element. |
name[i] | The i-th element with a particular name. |
[last()] | The last element. |
[last()-i] | The element i before the last element. |
name[@attrname="attrvalue"] | The first element with a particular name that contains the specified attribute-value pair.
Supports single and double quotes. (XML Only) |
. | The current element. |
.. | The parent element. |
XPath Examples
Assuming the following XML response:
<firstlevel> <one>value</one> <two> <item>first</item> <item>second</item> </two> <three>value three</three> </firstlevel>
Or, alternatively, the following JSON response:
{ "firstlevel": { "one": "value", "two": ["first", "second"], "three": "value three" } }
Here are some examples of valid XPaths:
Description | XML XPath | JSON XPath |
Document root | / | /json |
Specific element | /firstlevel/one | /json/firstlevel/one |
i-th child | /firstlevel/two/item[2] | /json/firstlevel/two/[2] |
This is not an exhaustive list by any means, but should provide a general idea of the possibilities.
The current element is specified via the XPath configuration setting. This configuration setting is read-only.
The current element is specified in the XPath configuration setting. This configuration setting is read-only.
HTTP Config Settings
When True, the control adds an Accept-Encoding header to the outgoing request. The value for this header can be controlled by the AcceptEncoding configuration setting. The default value for this header is "gzip, deflate".
The default value is True.
If set to True (default), the control will automatically use HTTP/1.1 if the server does not support HTTP/2. If set to False, the control fails with an error if the server does not support HTTP/2.
The default value is True.
This property is provided so that the HTTP control can be extended with other security schemes in addition to the authorization schemes already implemented by the control.
The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".
The default value is False.
If this property is set to 2 (Same Scheme), the new URL is retrieved automatically only if the URL Scheme is the same; otherwise, the control fails with an error.
Note: Following the HTTP specification, unless this option is set to 1 (Always), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.
Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty, unless this property is set to 1 (Always), in which case the same credentials are used to connect to the new server.
A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).
The default value is 0 (Never). In this case, redirects are never followed, and the control fails with an error instead.
Following are the valid options:
- 0 - Never
- 1 - Always
- 2 - Same Scheme
- "1.0"
- "1.1" (default)
- "2.0"
- "3.0"
When using HTTP/2 ("2.0"), additional restrictions apply. Please see the following notes for details.
HTTP/2 Notes
When using HTTP/2, a secure Secure Sockets Layer/Transport Layer Security (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/2 will result in an error.
If the server does not support HTTP/2, the control will automatically use HTTP/1.1 instead. This is done to provide compatibility without the need for any additional settings. To see which version was used, check NegotiatedHTTPVersion after calling a method. The AllowHTTPFallback setting controls whether this behavior is allowed (default) or disallowed.
HTTP/3 Notes
HTTP/3 is supported only in .NET and Java.
When using HTTP/3, a secure (TLS/SSL) connection is required. Attempting to use a plaintext URL with HTTP/3 will result in an error.
The format of the date value for IfModifiedSince is detailed in the HTTP specs. For example:
Sat, 29 Oct 2017 19:43:31 GMT.
The default value for KeepAlive is .
0 (None) | No events are logged. |
1 (Info - default) | Informational events are logged. |
2 (Verbose) | Detailed data are logged. |
3 (Debug) | Debug data are logged. |
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).
The headers must follow the format "header: value" as described in the HTTP specifications. Header lines should be separated by CRLF (Chr$(13) & Chr$(10)) .
Use this configuration setting with caution. If this configuration setting contains invalid headers, HTTP requests may fail.
This configuration setting is useful for extending the functionality of the control beyond what is provided.
.NET
Http http = new Http();
http.Config("TransferredRequest=on");
http.PostData = "body";
http.Post("http://someserver.com");
Console.WriteLine(http.Config("TransferredRequest"));
C++
HTTP http;
http.Config("TransferredRequest=on");
http.SetPostData("body", 5);
http.Post("http://someserver.com");
printf("%s\r\n", http.Config("TransferredRequest"));
Note: Some servers (such as the ASP.NET Development Server) may not support chunked encoding.
The default value is False and the hostname will always be used exactly as specified. Note: The CodePage setting must be set to a value capable of interpreting the specified host name. For instance, to specify UTF-8, set CodePage to 65001.
When True (default), the control will check for the existence of a Proxy auto-config URL, and if found, will determine the appropriate proxy to use.
Override the default with the name and version of your software.
TCPClient Config Settings
If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.
Note: This setting is provided for use by controls that do not directly expose Firewall properties.
Note: This setting is provided for use by controls that do not directly expose Firewall properties.
Note: This configuration setting is provided for use by controls that do not directly expose Firewall properties.
0 | No firewall (default setting). |
1 | Connect through a tunneling proxy. FirewallPort is set to 80. |
2 | Connect through a SOCKS4 Proxy. FirewallPort is set to 1080. |
3 | Connect through a SOCKS5 Proxy. FirewallPort is set to 1080. |
10 | Connect through a SOCKS4A Proxy. FirewallPort is set to 1080. |
Note: This setting is provided for use by controls that do not directly expose Firewall properties.

Note: This value is not applicable in macOS.
In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.
In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.
The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the control returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).
Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.
In multi-homed hosts (machines with more than one IP interface) setting LocalHost to the value of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface.
If the control is connected, the LocalHost setting 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 multi-homed hosts (machines with more than one IP interface).
Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.
LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.
This; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.
If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.
If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.
The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

Note: This value is not applicable in Java.
By default, this config is set to false.
0 | IPv4 Only |
1 | IPv6 Only |
2 | IPv6 with IPv4 fallback |
SSL Config Settings
When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.
Enabling this setting has no effect if SSLProvider is set to Platform.
The path set by this property should point to a directory containing CA certificates in PEM format. The files each contain one CA certificate. The files are looked up by the CA subject name hash value, which must hence be available. If more than one CA certificate with the same name hash value exist, the extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). OpenSSL recommends to use the c_rehash utility to create the necessary links. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The file set by this property should contain a list of CA certificates in PEM format. The file can contain several CA certificates identified by
-----BEGIN CERTIFICATE-----
... (CA certificate in base64 encoding) ...
-----END CERTIFICATE-----
sequences. Before, between, and after the certificates text is allowed which can be used e.g. for descriptions of the certificates. Please refer to the OpenSSL man page SSL_CTX_load_verify_locations(3) for details.
The format of this string is described in the OpenSSL man page ciphers(1) section "CIPHER LIST FORMAT". Please refer to it for details. The default string "DEFAULT" is determined at compile time and is normally equivalent to "ALL:!ADH:RC4+RSA:+SSLv2:@STRENGTH".
By default OpenSSL uses the device file "/dev/urandom" to seed the PRNG and setting OpenSSLPrngSeedData is not required. If set, the string specified is used to seed the PRNG.
If set to true, the control will reuse the context if and only if the following criteria are met:

When set to 0 (default) the CRL check will not be performed by the control. When set to 1, it will attempt to perform the CRL check, but will continue without an error if the server's certificate does not support CRL. When set to 2, it will perform the CRL check and will throw an error if CRL is not supported.
This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
When set to 0 (default) the control will not perform an OCSP check. When set to 1, it will attempt to perform the OCSP check, but will continue without an error if the server's certificate does not support OCSP. When set to 2, it will perform the OCSP check and will throw an error if OCSP is not supported.
This configuration setting is only supported in the Java, C#, and C++ editions. In the C++ edition, it is only supported on Windows operating systems.
Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.
Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.
When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.
By default, the enabled cipher suites will include all available ciphers ("*").
The special value "*" means that the control will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.
Multiple cipher suites are separated by semicolons.

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:
- TLS_AES_256_GCM_SHA384
- TLS_CHACHA20_POLY1305_SHA256
- TLS_AES_128_GCM_SHA256
SSLEnabledCipherSuites is used together with SSLCipherStrength.
Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:
TLS1.3 | 12288 (Hex 3000) |
TLS1.2 | 3072 (Hex C00) (Default) |
TLS1.1 | 768 (Hex 300) (Default) |
TLS1 | 192 (Hex C0) (Default) |
SSL3 | 48 (Hex 30) [Platform Only] |
SSL2 | 12 (Hex 0C) [Platform Only] |
SSLEnabledProtocols - TLS 1.3 Notes
By default when TLS 1.3 is enabled the control will use the internal TLS implementation when the SSLProvider is set to Automatic for all editions.
In editions which are designed to run on Windows SSLProvider can be set to Platform to use the platform implementation instead of the internal implementation. When configured in this manner, please note that the platform provider is only supported on Windows 11 / Windows Server 2022 and up. The default internal provider is available on all platforms and is not restricted to any specific OS version.
If set to 1 (Platform provider) please be aware of the following notes:
- The platform provider is only available on Windows 11 / Windows Server 2022 and up.
- SSLEnabledCipherSuites and other similar SSL configuration settings are not supported.
- If SSLEnabledProtocols includes both TLS 1.3 and TLS 1.2 the above restrictions are still applicable even if TLS 1.2 is negotiated. Enabling TLS 1.3 with the platform provider changes the implementation used for all TLS versions.
SSLEnabledProtocols: SSL2 and SSL3 Notes:
SSL 2.0 and 3.0 are not supported by the control when the SSLProvider is set to internal. To use SSL 2.0 or SSL 3.0, the platform security API must have the protocols enabled and SSLProvider needs to be set to platform.
This setting is only applicable when SSLProvider is set to Internal.
If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.
When set, the control will save the session secrets in the same format as the SSLKEYLOGFILE environment variable functionality used by most major browsers and tools such as Chrome, Firefox, and cURL. This file can then be used in tools such as Wireshark to decrypt TLS traffice for debugging purposes. When writing to this file the control will only append, it will not overwrite previous values.
Note: This setting is only applicable when SSLProvider is set to Internal.
Note: For server components (e.g. TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example:
server.Config("SSLNegotiatedCipher[connId]");
Note: For server components (e.g.TCPServer) this is a per-connection setting accessed by passing the ConnectionId. For example:

This functionality is currently not available when the provider is OpenSSL.
The value of this setting is a newline (CrLf) separated list of certificates. For instance:
-----BEGIN CERTIFICATE----- MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw ... eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w F0I1XhM+pKj7FjDr+XNj -----END CERTIFICATE----- \r \n -----BEGIN CERTIFICATE----- MIIEFjCCAv6gAwIBAgIQetu1SMxpnENAnnOz1P+PtTANBgkqhkiG9w0BAQUFADBp .. d8q23djXZbVYiIfE9ebr4g3152BlVCHZ2GyPdjhIuLeH21VbT/dyEHHA -----END CERTIFICATE-----
When specified the control will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the control fails with an error.
The format of this value is a comma separated list of hash-signature combinations. For instance:
component.SSLProvider = TCPClientSSLProviders.sslpInternal;
component.Config("SSLEnabledProtocols=3072"); //TLS 1.2
component.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
The default value for this setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.
In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.
The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.
When using TLS 1.2 and SSLProvider is set to Internal, the values refer to the supported groups for ECC. The following values are supported:
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1" (default)
The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.
Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.
In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.
The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072
The values are ordered from most preferred to least preferred. The following values are supported:
- "ecdhe_x25519" (default)
- "ecdhe_x448"
- "ecdhe_secp256r1" (default)
- "ecdhe_secp384r1" (default)
- "ecdhe_secp521r1"

- "rsa_pss_sha256" (default)
- "rsa_pss_sha384" (default)
- "rsa_pss_sha512" (default)
The default value is ecdhe_x25519,ecdhe_x448,ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1,ffdhe_2048,ffdhe_3072,ffdhe_4096,ffdhe_6144,ffdhe_8192
The values are ordered from most preferred to least preferred. The following values are supported:

Note: This option is not valid for UDP ports.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the control is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
