SftpFileTransferData event


Fires during file transfer, allowing you to alter file contents.

Syntax

  • Basic
Private Sub object_SftpFileTransferData(User, FileData())  
The SftpFileTransferData(object,User,FileData) syntax has these parts:
objectA wodSSHD object.
UserA SSHUser object. Reference to user whose file data is altered.
FileDataAn array of Byte values. Actual data as byte array (SAFEARRAY(unsigned char *) for VC++ users).

Remarks

SftpFileTransferData event is fired 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 wodSSHD1_SftpFileTransferData(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 events (and their ResolvedPath argument) to redirect wodSSHServer to some temporary file.
