This message queries the application page window handle associated with the specified page.
Syntax
param1 ULONG ulPageId; /* Page ID. */ param2 ULONG ulReserved; /* Reserved value, should be 0. */
Parameters
- ulPageId (ULONG) - Input
- Page identifier of the page whose window handle is requested.
- ulReserved (ULONG) - Input
- Reserved value, should be 0.
Returns
- hwndPage (HWND) - returns
- Handle of the application page window associated with the specified page identifier:
- BOOKERR_INVALID_PARAMETERS: An invalid page ID was specified for the ulPageId parameter.
- NULLHANDLE: No application page window handle is associated for the page specified in the ulPageId parameter.
- Other: Handle of the application page window associated with the specified page identifier.
Remarks
The application page window handle is set by using the BKM_SETPAGEWINDOWHWND message.
Default Processing
The default window procedure does not expect to receive this message and therefore takes no action on it other than to return NULLHANDLE.
