(VB.NET UWP/WinRT) Using the FTP Session Log

The Chilkat FTP component can keep a session log if the KeepSessionLog property is turned on. This is helpful in debugging problems. Chilkat support will usually ask for a session log when working to resolve your problem, because it contains a log of the exact commands sent to the FTP server, and the exact responses received.

' This example requires the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim ftp As New Chilkat.Ftp2

ftp.Hostname = "ftp.example.com"
ftp.Username = "login"
ftp.Password = "password"

' Set the KeepSessionLog property in order to keep a session log.
' The session log will continuously grow in memory.  The
' ClearSessionLog method may be called to clear it.  The session
' logging may be turned on/off at any point.
ftp.KeepSessionLog = True

' Connect and login to the FTP server.
Dim success As Boolean = Await ftp.ConnectAsync()
If (success <> True) Then
    Debug.WriteLine(ftp.LastErrorText)

' Change to the remote directory where the existing file is located.
success = Await ftp.ChangeRemoteDirAsync("junk")
If (success <> True) Then
    Debug.WriteLine(ftp.LastErrorText)

' To clear the SessionLog at any point, call ClearSessionLog:
' call ftp.ClearSessionLog();

' Append moreHamlet.txt to hamlet.txt on the FTP server.
Dim localFilename As String = "moreHamlet.txt"
Dim remoteFilename As String = "hamlet.txt"

success = Await ftp.AppendFileAsync(localFilename,remoteFilename)
If (success <> True) Then

End If


success = Await ftp.DisconnectAsync()

' Display the entire session log:
Debug.WriteLine(ftp.SessionLog)

Debug.WriteLine("File Appended!")
