Masking the mouse in MFC programs

The blocking mouse function needs to use the hook, the use process is as follows:

1. Defining global Variables

Hhook g_hmouse = NULL;

2. defining global Callback functions

LRESULT CALLBACK mouseproc (int ncode,wparam wparam,lparam LPARAM) {return 1;}

3. Mounting Hooks

G_hmouse = SetWindowsHookEx (Wh_mouse,mouseproc,null,getcurrentthreadid ());

After this line of code is executed, the application's mouse is masked.

4. Remove Hooks

UnhookWindowsHookEx (G_hmouse);

After this line of code is executed, the hook is removed and the mouse is re-restored.
