This message is sent to the application by the Help Manager to notify it that an extended help window has not been defined.
Syntax
param1 ULONG ulReserved; /* Reserved value, should be 0. */ param2 ULONG ulReserved; /* Reserved value, should be 0. */
Parameters
- ulReserved (ULONG) - input
- Reserved value, should be 0.
- ulReserved (ULONG) - input
- Reserved value, should be 0.
Returns
- ulReserved (ULONG) - return
- Reserved value, should be 0.
Remarks
When the extended help window is requested, the Help Manager searches the help table for its identity. If the extended help window identity associated with the current active window is zero, the Help Manager sends this message to the application to notify it that an extended help window has not been defined. The application then can:
- Ignore the request for help and not display a help window.
- Display its own window.
- Use the HM_DISPLAY_HELP message to tell the Help Manager to display a particular window.
Default Processing
None.
