Hi Steve,
Here is my understanding on your problem. Please let me if I get something
wrong.
//-----------
it is an ownerdrawn button
in the DRAWITEMSTRUCT, you specified the ODS_NOACCEL for itemState
the button is used in an AX control
1> host the ax control in IE -> press alt -> the button is painted with a
underscore
2> host the ax control in a normal win32 ap -> press alt -> mainframe menu
is underscored rather than the button
//--------------
In IE, when we press ALT key, WM_CHANGEUISTATE and WM_UPDATEUISTATE
messages are sent to specified window and all its child windows, so the
button is repainted with the underscore. But a normal win32 app does not
send these, so parent of the button will not get WM_DRAWITEM messages at
all!,
