The only way I know of to do this is calling the Win32 API manually. First you get the process ID by iterating through the running processes, compare the process EXE file name until you find the one you want, then get the hWnd and send it a message asking for it's state.
Here's a link that might help with iterating through the running processes:

As you can see (assuming you look at the link) this is not for the faint of heart. I recommend you get a book if you really want to get into doing things with the Windows API.
