Question

I need to intercept SendMessage API to prevent someone getting text from a particular window by sending WM_GETTEXT . so please suggest me how to do this

Was it helpful?

Solution

The easiest solution would be to simply subclass the window procedure of the target HWND and discard any WM_GETTEXT messages that you do not invoke yourself.
