View source for HM GENERAL HELP UNDEFINED

{{DISPLAYTITLE:HM_GENERAL_HELP_UNDEFINED}}
This message is sent to the application by the Help Manager to notify it that
a general help window has not been defined.

==Syntax==
<pre>
param1
ULONG ulReserved; /* Reserved value, should be 0. */

param2
ULONG ulReserved; /* Reserved. */
</pre>

==Parameters==
;ulReserved ([[ULONG]]) - input: Reserved value, should be 0.
;ulReserved ([[ULONG]]) - input: Reserved.
::0: Reserved value, 0.

==Returns==
;ulReserved ([[ULONG]]) - return: Reserved value, should be 0.

==Remarks==
When the general help window is requested, the Help Manager searches the help table for its identity. If the general help window identity associated with the current active window is zero, the Help Manager sends this message to the application to notify it that a general help window has not been defined. The application can then:
* 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.
