'''''''''''''''''Above From NET using Import WinSCP vb.net

When I use the GUI it sends the file and keeps the file name. I see it on the server.
When I use the .NET it sends the file but the name becomes blank on the server.
I do a For Each transfer In transferResult.Transfers
it shows I sent the file and reports back to me the correct file name it does not appear to have an error.
sorry for the delay in the response.

Please attach a full session log file both from GUI and the .NET assembly (using the latest version of WinSCP).

When I used the GUI of WinSCP and upload a file it works fine.
I use the script to upload the file and the filename becomes blank '' NO NAME.
When I check transferResult.Check() it reports that the filename "FileName.txt" was uploaded correctly.
The client shows me the file on his server and the file name is '' Blank.
But it works with the GUI
Here is the snippet of coded used.
transferResult = session.PutFiles(FtpsApiResponse.FileLocation & _ FtpsApiResponse.FileName,_FtpsApiResponse.ChangeDirectory, False, transferOptions)
transferResult.Check()
mSucccess = "IsSuccess:" & transferResult.IsSuccess.ToString() & "</br> "
'mSuccess returns True
For Each transfer In transferResult.Transfers
mSucccess = mSucccess & " File Transferred:" & transfer.FileName & "</br> "
Next
Response.Write(mSucccess)
I see that the file has been uploaded.

Here below are some of the option I have set. I have tried different combinations but nothing seems works.
transferOptions.FilePermissions = Nothing
transferOptions.PreserveTimestamp = False
transferOptions.ResumeSupport.State = TransferResumeSupportState.Off
