C # window interception of Keyboard Events

Sometimes it is necessary to intercept keyboard events so that the program can be executed according to the designer's requirements.

Protected override void WndProc (ref Message m)
{
Const int WM_HOTKEY = 0x0312; // hotkey message
If (m. Msg = WM_HOTKEY)
{
// Max. Minimal hotkey

}

// When the center pulley event is right-clicked, the screen saver timer is cleared. [9/15/2010 huzhonghua]
Const int WM_LBUTTONDOWN = 0x0201;
Const int WM_RBUTTONDOWN = 0x0204;
Const int WM_MOUSEDOWN = 0x0210;
Const int WM_MOUSEWHEEL = 0x020A;
If (m. Msg = WM_MOUSEDOWN | m. Msg = WM_LBUTTONDOWN | m. Msg = WM_RBUTTONDOWN | m. Msg = WM_MOUSEWHEEL)
{
// All Keyboard Events

}
Base. WndProc (ref m );
}
