    Re: App.PrevInstance

    from the docs:
    "The m_hPrevInstance data member is always set to NULL in a Win32 application. To find previous instances of an application, use CWnd::FindWindow."

    you can also search the C++ Forum for CreateFileMapping. Someone posted a solution that uses shared memory to find out if another instance of the app is running.

    Go to PJ Naughter's Home Page at http://indigo.ie/~pjn/

    Check his Misc Freeware section for CSingleInstance, it is great

    While you are there check the rest of his site. Some very interesting stuff.
