I need to run an application by stating its associated file....

emulating when you click on a known file type in a drive window and having windows start the editor for that file type and loading the file to edit that I clicked on....

Can you tell me how you do that???

Do you know how I have the calling program wait until the called program exits?

The simplest method would be:

        Dim p As Process = Process.Start("c:\someFile.ext")
        p.WaitForExit()

*** BUT *** this locks up the calling process until the spawned process exits.

You can use a Polling loop like this though:

        Dim p As Process = Process.Start("c:\someFile.ext")
        While Not p.HasExited
            System.Threading.Thread.Sleep(100)
            Application.DoEvents()
        End While

If a polling loop is unacceptable then encapsulate the Process() in a Class and place it on a different thread.  Then you use WaitForExit() without locking up your GUI.  Make the Class raise a custom event when the Process is complete.  Since you are using Threads, you would need to Marshal the event back onto the main UI using a Delegate and Invoke().  Let me know if you want to see an example of this...
