SAMPLE: Code Demonstrates Windows 3.1 WH_MOUSE Hook

• Microsoft Windows Software Development Kit (SDK) for Windows version 3.1

MOUSHOOK is a file in the Software Library that demonstrates installing and using a WH_MOUSE mouse message hook. The mouse message hook in MOUSHOOK disables the right mouse button for all applications in the system by discarding WM_RBUTTONDOWN and WM_NCRBUTTONDOWN messages. The mouse hook function beeps each time it discards a message.

The MOUSHOOK file contains the source to an application program, TESTAPP, and a dynamic-link library (DLL), MOUSHOOK, that implements the mouse hook. The MOUSHOOK DLL uses the new hook functions provided by Windows 3.1: SetWindowsHookEx(), UnhookWindowsHookEx(), and CallNextHookEx().

TESTAPP calls MOUSHOOK to install the mouse hook. When TESTAPP is closed, it removes the mouse hook from the system.
