Remarks

When the Help Manager receives this message, it sends a HM_QUERY_KEYS_HELP message to the active application window. The active application window is the window that was specified when the last HM_SET_ACTIVE_WINDOW message was sent. If no HM_SET_ACTIVE_WINDOW message was issued, then the active application window is the window specified in the WinAssociateHelpInstance call.

The application must return one of the following:

• The identity of a keys help window in the usHelpPanel parameter of the HM_QUERY_KEYS_HELP message.
• Zero, if no action is to be taken by the Help Manager for keys help.

Default Processing

None.
