I have tried creating a window handle and pointing that to windows proc. But I am unable to find any information online that will allow me to point the desktop handle to the windows proc

That makes no sense at all.

I don't think anyone has any clue what you're trying to do with the desktop window handle.

I think what he wants to do is write a WndProc that will process messages sent to the desktop window. Methinks the only way to do that is by creating a hook.

Possibly. But is he trying to just listen for the Desktop window messages or every window being shown?

Don't know....

Yeah. So I want to listen to all the messages that are being sent by the mouse, keyboard and touch input, on the everything that is there on the screen. I thought getdesktopwindow() may provide a handle to everything on the screen. Apologies, if my knowledge is incorrect as I have started using winAPI very recently.

I think you may need to build a Windows hook to process messages destined for the desktop window. See this[^] MSDN article and this CP article: Using Window Messages to Implement Global System Hooks in C#[^].

@Ravi Bhavnani: Hey Ravi, I was able to use hooks to detect mouse and keyboard events but I am unable to figure out how I can detect touch based events using that.

See https://www.codeproject.com/Articles/381673/Using-the-RawInput-API-to-Process-MultiTouch-Digit.

@Ravi Bhavnani: I was able to detect touch input using global hooks, as was suggested by you. Any idea why it doesn't work around the region covered by the internet explorer but that's not the case anywhere else on the screen
