SUMMARY
HookAll.exe is a sample program in the Software Library that demonstrates the use of WH_GETMESSAGE and WH_CALLWNDPROC hooks. The sample contains the code for a dynamic-link library (DLL) with functions to set and remove the hooks, as well as the hook filter functions. The filter functions use OutputDebugString to display a message when they receive a WM_LBUTTONDOWN message. The sample also contains code for an application that tests the DLL.
