The easiest way is to use SendKeys.Send: http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.send(v=vs.110).aspx You first need to force the input focus onto the 'Receiver' application. You then need to send the appropriate keystrokes to change the focus to the textbox and to send the text itself. The code to do all this would be on the following lines: using System.Diagnostics; using System.Runtime.InteropServices; // within Form class of 'Sender' application [DllImport("user32.dll")] private static extern bool SetForegroundWindow(IntPtr hWnd); // within some method of that Form Process[] procs = Process.GetProcessesByName("notepad"); // or whatever if (procs.Count > 0) { IntPtr hWnd = procs[0].MainWindowHandle; SetForegroundWindow(hWnd); SendKeys.Send(someString); }
