HM_ACTIONBAR_COMMAND
usCmd = (USHORT) SHORT1FROMMP(mp1);   /* command value */
 
The HM_ACTIONBAR_COMMAND message is sent when the user chooses a command
from an application-supplied menu in the help window. The application should
carry out the command identified by the usCmd parameter.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
usCmd      Low word of mp1. Specifies the command value.
 
Return Value
 
An application should return zero if it processes this message.
 
Comments
 
Applications can replace the menu in a help window by specifying a menu ID
in the HELPINIT structure used when the help instance is created by using
the WinCreateHelpInstance function. If an application replaces the menu, it
receives the HM_ACTIONBAR_COMMAND message when the user chooses a command
from the menu. Application-supplied menus should have command values in the
range 0x7F00 through 0x7FFF.
