Actually, if you click OK, message box returns 1024.  Which is the value 
of the enum of StandardButton.  So you're seeing normal termination, but 
if the Ok button were the result, then the exit code would be 1024.  It 
will return the error code based on what the application returns, not 
the messagebox.
