CMFCToolBar::GetHwndLastFocus
Returns a handle to the window that had the input focus just before the toolbar did.
HWND GetHwndLastFocus() const;
Return Value
A handle to window that is not derived from CMFCBaseToolBar Class, which previously had the input focus; or NULL if there is no such window.
Remarks
When a CMFCToolBar Class control receives the input focus, it stores a handle to the window that lost the focus so that it can restore it later.
