You'll need a method that queries the state of the second application.

This is easy. Create a method that checks if the form is visible or not. (Hint: use the

How can I put this simply? If you want to know if application B is visible or not, then application A is going to have to query it and ask it if it is visible or not. Hence, application B will have to provide this information. That's what we've been telling you all along. There's no easy way for the first application to know this - it's the responsibility of the second app to tell it.

I would have the application that shows/hides create a named
Mutexwhen it is visible. It can release theMutexwhen it gets hidden. The calling app can try and create the same namedMutexand if it fails, it knows the application is visible. If it succeeds, it releases theMutexand knows that the application is hidden. -
