How to prevent more than one instance of MFC application.

[Simon Pettman]

I have an MFC application that uses a third party .dll for a data aquistition card. The application crashes if a user trys to open two instances of the same application.

Is there any way that when the executable is run it checks to see if a version of itself is already running and the brings up that version and exits.

Can this be done within the MFC framework.
