Hi everyone, I have a MFC application that is dialog based. I now want to add the option to "close" the application but have it running in the tray. And if the application is not selected to go to they tray, it must still operate as the normal dialog based application. How do I do this and where in my program do I place all the commands, etc. Thanks,

Here''s the steps

1. Override OnClose for the dialog
i. Don't close the dialog (default base class calls DestroyWindow)
ii. Instead hide the dialog using something like
ShowWindow (SW_HIDE)
iii. Create a dummy hidden window (using CreateWindow)
iv. Add an item to the system tray using Shell_NotifyIcon (NIM_ADD, and a NOTIFYICONDATA structure are parameters).  The NOTIFYICONDATA message includes the hWnd of the dummy hidden window - this window will receive messages when the icon is clicked on or whatever.

2.In the dummy hidden window code
i. Wait for double click or whatever
ii. When you get one, reshow the dialog using ShowWindow
iii. Destroy the dummy hidden window

BTW - how does the user really close your app ?  Might it be better to do it on minimizing ?

One final point, when debugging I suggest you make the dummy window visible and don't bother show/hiding the dialog.  After the basic structure is working then add the code to hide the dummy window and show/hide the app's dialog.
