Note This function can be re-entered when called within certain message handlers, causing unexpected results. Take care to avoid a reentrant call when handling any of the following messages: WM_ACTIVATE, WM_ACTIVATEAPP, WM_NCACTIVATE, WM_PAINT; WM_SYSCOMMAND if wParam is set to SC_HOTKEY or SC_TASKLIST; and WM_SYSKEYDOWN (when processing Alt-Tab or Alt-Esc key combinations). This is an issue with single-threaded apartment model applications.
