Hi,
I am using the asynch method of DownloadMultiple to download all files with wildcard *.csv from an FTP server. The problem is that although no errors are appearing, the file in the local folder never gets overwritten. Only the first time only. What could I be doing wrong here? I also tried the same with synchronous methods and got the same result. Here is my code:
'Open Connection
With FTPConnection
.ServerAddress = txtIP.Text
.UserName = txtUser.Text
.Password = txtPass.Text
Try
.BeginConnect(New AsyncCallback(AddressOf OnConnect), FTPConnection)
.BeginChangeWorkingDirectory("backup", New AsyncCallback(AddressOf OnChangeDirectory), FTPConnection)
Catch ex As Exception
MessageBox.Show("An error occurred while trying to connect to the exchange rate server. The error is :" + ex.Message)
End Try
End With
'Download files
FTPCon.BeginDownloadMultiple(txtLocalPath.Text, FTPCon.ServerDirectory, "*.csv", False, New AsyncCallback(AddressOf OnDownloadMultiple), FTPCon)
Private Sub OnConnect(ByVal ar As IAsyncResult)
Dim c As ExFTPConnection = CType(ar.AsyncState, ExFTPConnection)
c.EndConnect(ar)
Console.WriteLine("Connect completed")
End Sub 'OnConnect
Private Sub OnChangeDirectory(ByVal ar As IAsyncResult)
Dim c As ExFTPConnection = CType(ar.AsyncState, ExFTPConnection)
c.EndChangeWorkingDirectory(ar)
Console.WriteLine("Changed directory completed")
End Sub 'OnUpload
Private Sub OnDownloadMultiple(ByVal ar As IAsyncResult)
Dim c As ExFTPConnection = CType(ar.AsyncState, ExFTPConnection)
c.EndDownloadMultiple(ar)
Console.WriteLine("Download filtered files completed")
End Sub 'OnDownload
Private Sub OnClose(ByVal ar As IAsyncResult)
Dim c As ExFTPConnection = CType(ar.AsyncState, ExFTPConnection)
c.EndClose(ar)
Console.WriteLine("Close completed. Signalling main thread")
signaller.Set()
End Sub 'OnClose
Private signaller As New ManualResetEvent(False)
thanks
