[2005] Calling a hidden application

I need the VB application to execute an external application so that it is hidden. The options in shell() don't include really hiding it. Somebody told me there's an API function that does that, but I have no idea how to call it and everything. Can somebody help? :afrog:

Create a ProcessStartInfo object. Set its properties appropriately, including the CreateNoWindow property to True. Call Process.start and pass your PSI as a parameter.
