SAMPLE: MousHook.exe Demonstrates Windows 3.1 WH_MOUSE Hook

ID: Q81333

The information in this article applies to:

SUMMARY

MousHook.exe is a sample that demonstrates how to install and use a WH_MOUSE mouse message hook. The mouse message hook in MousHook.exe 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.

MousHook.exe contains the source to an application program, TESTAPP, and a dynamic-link library (DLL), MousHook.dll, 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.
