C# how to hang a mousemove event on the screen?

Question

Programming

I create a drag & drop of the entire window, you can drag for a certain area.
The problem is that you need to hang the mouse movement event on the screen, that is, so that the listener is called even when I move the cursor outside the program window. I can only hang on a window or its elements, but I didn’t find how to do this.

Answer 1

Dig towards Mouse Capture and don't listen to all sorts of hooks. This mechanism will allow you to catch mouse events even if the mouse is not in the focus of your window.

You need to use the global mouse hook via SetWindowsHookEx https://msdn.microsoft.com/en-us/library/ms644990(...
