[RESOLVED] exception "CTL_E_GETNOTSUPPORTED"

[makdu]

HI,
I am trying to dial a computer from another computer using Modem for sending files and messge.Follwoing is the code done in dialing computer

Text1.Text = "Test string from App1 "
        Number$ = InputBox$("Enter phone number:", "Number$")
        If Number$ = "" Then Exit Sub
        Temp$ = Status
           Status = "Dialing - " + Number$
        DialString$ = "ATDT" + Number$ + ";" + vbCr

        On Error Resume Next
        If MSComm1.PortOpen = False Then
            MSComm1.CommPort = 4
            MSComm1.Settings = "9600,N,8,1"
            MSComm1.PortOpen = True
            MSComm1.RThreshold = 1
            MSComm1.RTSEnable = True
            MSComm1.SThreshold = 1
            'MSComm1.Handshaking = MSCommLib.HandshakeConstants.comRTS
        End If

        MSComm1.Output = DialString$
        Do
     
            Temp$ = Temp$ & MSComm1.Input
                      If InStr(Temp$, "NO DIALTONE" & vbCrLf) Then
                End
            End If
        Loop Until InStr(Temp$, "OK" & vbCrLf)

                   MSComm1.Output = Text1.Text

But after the dial tone, i am getting the exception "CTL_E_GETNOTSUPPORTED " at the line MSComm1.Output = Text1.Text Can you please tell me what may be reason for this .

[jmcilhinney]

The error says that the GET operation is not supported so presumably the underlying COM object doesn't support getting the Output property value or something that it depends on.

[makdu]

But how this is happened in the given code. Any reason which will help me to find out the reason

[jmcilhinney]

I'm not familiar with the COM component your using but, regardless, I just realised that you're setting Output, not getting it. I have to say that I really don't know what the issue is but it's just another reason not to use COM, if you can avoid it.

What else i can use instead of COMM for data transfer between computers using a dial up modem ?

[formlesstree4]

Sockets maybe?

[makdu]

The error was with the inital setting of the port.
By modifying the same, i am able to do the data transfer
