>I have an application which supports the tray functionality. So, when minimized, the application appears in the tray. Normally, when this is the case for Outlook, if I would click on the Outlook icon on the desktop, the application would appear as is as it is already loaded. So, it will appear and be in the state in was previously to have been minimized. But, in my application, if I do the same thing, only a switch to the application is done. I would like it to detect that and get back to its previous state, thus maximized. Where should I hook that in the code to achieve that?
