  1. POC# Hooking a Console Application to Notepad
    text
    copied!<p>What i want to do is create a simple windows application that will hook itself onto NotePad and then simulate a keystroke. I have the process of opening up NotePad, bringing it to the foreground and then simulate the number 1 being pressed. However, if I click off of notepad, whatever is active becomes what is being typed in. </p> <p>How do I bind this application to notepad, so that I can click and type in whatever, and this application will still push commands into notepad? </p> <p><a href="http://inputsimulator.codeplex.com/" rel="nofollow">This is the DLL i'm using to simulate keypressing</a>: </p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.InteropServices; using System.Diagnostics; using WindowsInput; namespace NotePadTesting { class Program { [DllImport("USER32.DLL", CharSet = CharSet.Unicode)] public static extern IntPtr FindWindow(string lpClassName, string lpWindowName); // Activate an application window. [DllImport("USER32.DLL")] public static extern bool SetForegroundWindow(IntPtr hWnd); static void Main(string[] args) { Process[] processes = Process.GetProcessesByName("notepad"); if (processes.Length == 0) { Process.Start("notepad.exe"); processes = Process.GetProcessesByName("notepad"); } if (processes.Length == 0) { throw new Exception("Could not find notepad huh...."); } IntPtr WindowHandle = processes[0].MainWindowHandle; SetForegroundWindow(WindowHandle); for (int i = 0; i &lt; 500; i++) { System.Threading.Thread.Sleep(100); InputSimulator.SimulateKeyPress(VirtualKeyCode.VK_1); } } } } </code></pre>
