>>What's "best" is strictly a matter of opinion. I prefer using my Is_Run32 function (which is available in the download section under Win32 and other APIs). Some others might suggest trying to use DDE, but that's totally unreliable in my opinion, since the application must support it.

Hi Vlad,

I feel that DDE and OLE are, in general, less reliable. The app has to support it. There may be instances where I just need to know if, say, Notepad is running, or something else. I simply don't believe that it should be the responsibilty of one application to let another know that it's running. If my program needs to know that another app's running, then it's my app that should take the responsibility of finding that out. By using DDE or OLE, you're putting the responsibility on the other app.

Of course, that just IMHO. I could be wrong.
