HAB      hab;           /*  Anchor-block handle. */
LONG     idContext;     /*  Origin of call to hook. */
HWND     hwnd;          /*  Window handle. */
PSZ      pszClassName;  /*  Window class name. */
ULONG    usMsgClass;    /*  Message class. */
LONG     idControl;     /*  Control setting. */
PBOOL    fSuccess;      /*  Success indicator. */
BOOL     rc;            /*  Processing indicator. */

rc = MsgControlHook(hab, idContext, hwnd,
