Simple Code Work Nice On Window XP But Not On Windows 7

[.paul.]

Try this...

Dim objProcess As New Process
Dim intHwnd As IntPtr

With objProcess.StartInfo
    .FileName = "rundll32"
    .Arguments = String.Format("printui.dll,PrintUIEntry /e /n {0}{1}{0}", Convert.ToChar(34), "EPSON L130 Series")
    .UseShellExecute = False
End With
objProcess.Start()
objProcess.WaitForInputIdle()

intHwnd = objProcess.MainWindowHandle
objProcess.Dispose()

MessageBox.Show(intHwnd.ToString)
