/* This function is the Window Procedure for the screen saver. It is

* the following messages: * * WM_SYSCOMMAND: return FALSE if wParam is SC_SCREENSAVE or SC_CLOSE * * WM_DESTROY: PostQuitMessage(0) * * WM_SETCURSOR: By default, this will set the cursor to a null cursor, * thereby removing it from the screen. * * WM_LBUTTONDOWN: * WM_MBUTTONDOWN: * WM_RBUTTONDOWN: * WM_KEYDOWN: * WM_KEYUP: * WM_MOUSEMOVE: By default, these will cause the program to terminate. * Unless the password option is enabled. In that case * the DlgGetPassword() dialog box is brought up. * * WM_NCACTIVATE: * WM_ACTIVATEAPP: * WM_ACTIVATE: By default, if the wParam parameter is FALSE (signifying * that transfer is being taken away from the application), * then the program will terminate. Termination is * accomplished by generating a WM_CLOSE message. This way, * if the user sets something up in the WM_CREATE, a * WM_DESTROY will be generated and it can be destroyed * properly. * This message is ignored, however is the password option * is enabled. */LRESULT WINAPI DefScreenSaverProc(HWND, UINT, WPARAM, LPARAM);
