Hi there,

sorry my English is not so good. I am a hobby programmer and am writing a program that puts an in-game overlay on a game.

About my problem. I would like in the NVidia IN Game Overlay, prevent mouse input for the game as long as the overlay is active in an Fullscreen Game. But I don't know how I can do it. I use VB.Net or C Sharp. There is definitely an API that can be used to switch the mouse input for a process on and off.

Can anyone help me further?

What I have tried:

Bockinput
Handling Windows Messages 
Global Mouse Hooks

It involves "capturing" the mouse so the API function is SetCapture. Have a look at this for more information: Mouse Movement - Win32 apps | Microsoft Docs[^]

I see you have edited your question. I recommend that you search for the things you "have tried." If capturing the mouse is not what you want then try a global hook for mouse input. There are lots of articles on the topic here and you can type that into the search box as easily as I can.
