{{DISPLAYTITLE:MM_SETDEFAULTITEMID}}
This message is used to set the default item in a conditional cascade menu.

==Syntax==
<pre>
param1
ULONG ulDefItemID; /* The menu id of the item to become the new default. */

param2
ULONG ulReserved;  /* Reserved value, must be 0. */
</pre>

==Parameters==
;ulDefItemID ([[ULONG]]) - input: The menu id of the item to become the new default.
;ulReserved ([[ULONG]]) - input: Reserved value, must be 0.

==Returns==
;rc ([[BOOL]]) - return: Success of failure indicator.
::TRUE: The conditional cascade default was set.
::FALSE: The conditional cascade default was not set.

==Remarks==
The default item is the menu-id that will be returned if the main menu option
is clicked on.

    ┌─────────────┐
    │Open     (->)│  Icon
    └─────────────┤
      *Tree       │  id=MID_TREE
        Details   │  id=MID_DETAILS
    └─────────────┘

In the example above, where MID_TREE is currently the default, if the user
clicked on the "Open" option without opening the conditional cascade menu, the
menu would send back a notification that MID_TREE was selected.

==Default Processing==
The default window procedure takes no action other than to return 0.
