>Basically, what I wanted to do is that in my program, I have a button such that when the user presses it, it will bring up the Outlook. If the Outlook is already running, I don't wanted to run the 2nd instance of an Outlook. I just wanted to set the currently running Outlook window into maximize and set the current focus to Outlook as the currently selected program. And when he closes the Outlook, it will return the focus to my program.
