MORE INFORMATION

ADMENUAPP adds two menu items to the system menu of each application running under Windows. To do this, it uses two system-wide hooks: a WH_GETMESSAGE hook and a WH_CALLWNDPROC hook. Both of these hooks are implemented in ADMENULIB, a fixed-code DLL.

Whenever the WH_CALLWNDPROC hook function sees a WM_INITMENU message being sent to a top-level window, it appends the two new menu items to that window's system menu. The items are removed when the menu is closed.

The two menu items that are added appear as "New Menu Item 1" and "New Menu Item 2." If the user selects one of these items, the WH_GETMESSAGE hook procedure sees the resulting WM_COMMAND message and responds by posting a private message to ADMENUAPP. ADMENUAPP handles the private message by displaying a dialog box stating that one of the two added items was selected.
