I have a screen which displays client information, including
the phone #. I want to dial this # when I press the dial label button. It should also give me relevant error messages. ( eg. line engaged, invalid # etc. ) Any source code and other information will be greatly apprecaited.
I am new to VB. Dilantha (-:

VB 5.0 Pro/Ent comes with a sample application that does exactly what you want.Put an MSCOMM on your form, then add a push button that calls the following function:+----------+----------+
+----------+----------+
Private Sub Dial(Number$)
    Dim DialString$, FromModem$, dummy

    ' AT is the Hayes compatible ATTENTION command and is required to send commands to the modem.
    ' DT means "Dial Tone." The Dial command uses touch tones, as opposed to pulse (DP = Dial Pulse).
    ' Numbers$ is the phone number being dialed.
    ' A semicolon tells the modem to return to command mode after dialing (important).
    ' A carriage return, vbCr, is required when sending commands to the modem.
    DialString$ = "ATDT" + Number$ + ";" + vbCr

    ' Communications port settings.
    ' Assuming that a mouse is attached to COM1, CommPort is set to 2
    MSComm1.CommPort = 2
    MSComm1.Settings = "9600,N,8,1"
   
    ' Open the communications port.
    On Error Resume Next
    MSComm1.PortOpen = True
    If Err Then
       MsgBox "COM2: not available. Change the CommPort property to another port."
       Exit Sub
    End If
   
    ' Flush the input buffer.
    MSComm1.InBufferCount = 0
   
    ' Dial the number.
    MSComm1.Output = DialString$
   
    ' Wait for "OK" to come back from the modem.
    Do
       dummy = DoEvents()
       ' If there is data in the buffer, then read it.
       If MSComm1.InBufferCount Then
          FromModem$ = FromModem$ + MSComm1.Input
          ' Check for "OK".
          If InStr(FromModem$, "OK") Then
             ' Notify the user to pick up the phone.
             Beep
             MsgBox "Please pick up the phone and either press Enter or click OK"
             Exit Do
          End If
       End If
       
       ' Did the user choose Cancel?
       If CancelFlag Then
          CancelFlag = False
          Exit Do
       End If
    Loop
   
    ' Disconnect the modem.
    MSComm1.Output = "ATH" + vbCr
   
    ' Close the port.
    MSComm1.PortOpen = False
End Sub
