Capturing keystrokes

If I am working in an application and I press key from keyboard, how can I capture that key (or string), including the source application's name, using C#?

From stackoverflow

• You could override the ProcessCmdKey function of the control you want to capture the input from.

  protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
  {
      var msgFormat = "Key Pressed: [{0}] {1}";
      var appName = System.AppDomain.CurrentDomain.FriendlyName;
      var logMsg = String.Format(msgFormat, appName, keyData.ToString());
      // write msg to log
      return base.ProcessCmdKey(ref msg, keyData);
  }
  

  Hope that helps.

• There is a good keylogger example on codeproject.com. I hope this helps.

• You need to setup windows hooks to call your callback function for any keyboard event. You can use SetWindowsHookEx to set up windows hooks.
