Why in the world are you launching a Windows Forms application from a command prompt? I don't understand what you are trying to accomplish here. — Cody Gray - on strike, Feb 22 '11 at 05:25

I think you should use function FindWindow and SendMessage. Also you should overide WindProc in your C# application to process input messages.

Thank you very much. Finally, I created one more console application and sending messages to my winform app. – Harsha Feb 23 '11 at 05:04

I am not sure why you would want to do what you just described. But if you are looking at a generic way to control a winform application from another application, you can take a look at named pipes(.NET 3.5+). Otherwise you can do this by using a tcp socket in loopback mode.
