This seems kludgy to me. If you are going to be grabbing resources, grab a mutex or semaphore, which are designed for cross-process communication. Problem is (and this will be a problem with the solution below), since you are doing a NTD, you might not have the permissions to grab local resources. You have to p/invoke to get a semaphore, but you might be able to get a mutex since it's managed. I am not sure of the particulars, but hopefully you can research it from here.

Grab a resource on startup. If its not available, your client is still up. Be sure to clean up on exit. Examples: - Open a socket listener. - Open a file with write access. Saad .

I guess I will not know it from the process list as all I see is IEExec.exe (smart client is launched off an IE shortcut) corresponding to my smart client application.
