I’m using agsXMPP in my .NET project (WinForms)
I have the following Code block, this is executed whenever a message is received from any client.
Now whenever a message is received, this block executes and the program terminates.. 🙁
I’ve no idea as to what’s happening. Help!

Has this something to do with threads? (I’ve heard that agsXMPP encapsulates a thread on which it works)

   Private Sub messageReceived(ByVal sender As Object, ByVal msg As protocol.client.Message)
    Dim chatMessage() As String
    Static Dim Hi_ed As Integer = 0
    chatMessage = msg.From.ToString.Split("/")
    Dim chatSender As String = chatMessage(0)

    If Not IsWorking Then
        IsWorking = True
        If Not ProcessCommands(msg.Body, chatSender) Then
            Dim sStr As String = ParseEnglish(msg.Body)

            Select Case sStr
                Case "HI"
                    If Hi_ed = False Then
                        SendGTalkMsg("Hi. How do you do?", chatSender)
                        Hi_ed = True
                    Else
                        SendGTalkMsg("हाय वाई कुछ नहीं हम तो !!!", chatSender)
                    End If
                Case "DETAILS PLEASE"
                    SendGTalkMsg(". Currently there are N no of sams running on me: :)", chatSender)
            End Select
        End If
        IsWorking = False

        Exit Sub
    Else
        SendGTalkMsg("I'm working right now. Please have patience.", chatSender)
    End If
End Sub

** EDIT ****
Now, when I run the EXE file generated, after this event is done the “not-responding” error comes, which clearly means that there is an exception but it’s escaping the try catch block. 🙁

This is the error which I get:

    Well, well, well. It was all because of a silly dialog box for the

    My.Computer.Network.DownloadFile(SourceZipFile, DestinationZipFile, "<userid>", "<password>", True, 100000, True)

    was set to true. So whenever the file download progress box appeared, it used to mess up with the threads. When I changed the ShowUI parameter of DownloadFile to False everything worked fine. 🙂

    But do we have a clear explanation to this?
