How to prevent inputing into textbox?

I' m using this library to receive input message and handle it in background. But if the textbox got focused, the characters will still be typing there. How to prevent it?

If you want to intercept some of the input I guess you could try not calling the default window procedure when you receive the WM_INPUT you want to intercept.

Could you provide a code sample?

Read the docs and looks for samples online maybe:
https://docs.microsoft.com/en-us/windows/win32/inputdev/wm-input

I'm under the impression what you are trying to achieve has little to do with this library itself.
