Description
-
Called during file transfer, allowing you to alter file contents.
Return Type
-
None
Syntax
-
object.SftpFileTransferData User, FileData()
The SftpFileTransferData Method syntax has these parts:
| object |
An expression
evaluating to an object of type wodSSHD-Notifications. |
| Owner |
A wodSSHDCom object. Instance
of wodSSHServer that called this notification
method. |
| User |
A SSHUser object. Reference
to user whose file data is altered. |
|
FileData |
An array of Byte values.
Actual data as byte array (SAFEARRAY(unsigned char *) for VC++
users). |
- Remarks
-
This method is called only if you implemented
IwodSSHNotify interface in your application, and
wodSSHD.Notification
property has received reference to instance of your
implementation. SftpFileTransferData notification method is
called during file transfers, allowing you to alter contents of file
currently being uploaded/downloaded. It will fire only if
MonitorTransfers
property is set to appropriate value other than MonitorNone.
Since FileData is a byte array, file contents can be changed
in size and in values - you can supply new byte array to this
argument if needed. For example, following code will always destroy
all values in the array, and no matter how large files user tries to
upload (or download), it will always end up with zero sized file:
- Private Sub
IwodSSHD-Notifications_SftpFileTransferData(ByVal Owner As
wodSSHDComLIB.IwodSSHDCom, ByVal User As wodSSHDComLIB.ISSHUser,
FileData() As Byte)
Dim b() As Byte
DirData = b
End Sub
-
-
You should note, however, that when user uploads file, it will be
created - no matter if you change the contents or not. If you intend
to alter contents of file transfers, or even to disable writing them
to specified file, you can use
SftpUploadFile and
SftpDownloadFile notifications (and their ResolvedPath
argument) to redirect wodSSHServer to some temporary file.
