The .exe file is not located in the server. It's located in the clients.
The brief explanation of my problem is that I want the clients run an application downloaded by them before in order to send messages to the other clients on the network. I wrote the code and compiled to .exe. When they Submit a form, they will call the program with the proper parameters. If the program is not running, it will be; if not, the proper function of the .exe will be called.
I hope I could explain my problem. I'd be glad if you help me.
Thanks.
