trigger an event when an application stops

I have a program i wrote, lets call it ProgramA...  basically it opens another program lets call it ProgramZ, and gains a handle to the program using the User32.dll.  What im trying to do is have ProgramA display a message box when ProgramZ gets closed (when the user closes ProgramX).

You can have ProgramA dedicate a thread to using System.Diagnostics.Process.WaitForExit, and have the thread exit and raise the event in the UI thread.

sounds cool... how does that look in code?

Say you have this function "Vulture" (translating here from my C#) designed to wait for the dead.

(you'll need to import system.threading and system.diagnostics for this)

private pid as int

Sub Vulture()
    dim proc as Process = Process.GetProcessById(pid)
    proc.WaitForExit()
    MessageBox.Show("it died")
End Sub


You invoke this Sub from your code with:
                dim t as Thread  = new Thread(new ThreadStart(Vulture))
                t.Start()
and then go on with your code.
