ShellAndWait and Checking for Hangs

I am trying to use a shellandwait command on a net use batch file. However if the net use information is incorrect and it is asking for a password the cmd window will never close because it's waiting for input

I have tried using timers but can't seem to place it right, anyone have any ideas on how to achieve what I am looking for?

:confused:

This One?

This is what I have now:

Code:

---

Private Function shellAndWait(ByVal fileName As String) As Long
    'Execute the application/file, but HIDE the window
    Timer1.Interval = 1000
    Timer1.Enabled = True
    glPid = Shell(fileName, vbNormalFocus)
    If glPid = 0 Then
        MsgBox "Could not start process", vbExclamation, "Error"
    End If
   
    If timercnt = 3 Then
        shellAndWait = glPid
        Timer1.Enabled = False
    End If
End Function
Private Sub Timer1_Timer()
    timercnt = timercnt + 1
    If timercnt = 2 Then
        Dim i As Long
        '
        ' Enumerate all parent windows for the process.
        '
        Call fEnumWindows
        '
        ' Send a close command to each parent window.
        ' The app may issue a close confirmation dialog
        ' depending on how it handles the WM_CLOSE message.
        '
        For i = 1 To colHandle.Count
            glHandle = colHandle.Item(i)
        Call SendMessage(glHandle, WM_CLOSE, 0&, 0&)
        Next
        MsgBox (glPid)
        ErrorCode = "30"
        ErrorStatus = 1
    End If
End Sub

But this is not working the way I want, basically the timer is checking to make sure that it doesn't wait too long, shellandwait will just sit there otherwise if Net Use is asking for a password

After your message box saying it can't start, put Timer1.Enabled = False and see if that helps.
