I have a specific piece of software that is licensed by port numbers. I have plenty of licenses for the people that need to use it, but the people may be a a large number of computers. The problem lies in that the port for a specific computer is set in the registry. I have implemented a very functional port scanner using the winsock control that attempts to connect to a port, if it succeeds, then it changes the registry and launches the app. The only real problem is the time delay to "release" the port. I had to put a 30 second countdown timer in the launcher to make sure the port would be free at the time of the application launch. Does anyone know a way to scan a port to see if it is in use without tying up the port? David Moore
