WM_UPDATEFRAME
fsStyle = SHORT1FROMMP(mp1);    /* style flags */
 
The WM_UPDATEFRAME message is sent after frame controls have been added or
removed from the window frame. It tells the frame window to reformat and
update the appearance of the window. An application should send this message
to its frame window whenever it adds or removes frame controls.

Comments
 
Because this message causes any redrawing that is necessary, the application
should ensure that no drawing takes place when adding or removing a frame
control, to prevent unnecessary redrawing. If using the WinSetParent
function, this is done by setting the fRedraw parameter to FALSE.
