For this you would need inter process communication (ipc). See this question for more details about ipc in .net.

Generally speaking you're gonna need some form on inter-process communication for these two apps to talk to one another. The simplest option in your case (though by far not the most reliable) is to use System.Windows.Forms.SendKeys.Send().
