The FlashWindowEx function flashes the specified window. Using this function, you can specify the number of times the system will flash the window, whereas the FlashWindow function flashes the window only once.
BOOL FlashWindowEx(
PFLASHWINFO pfwi
);
The return value specifies the window's state before the call to the FlashWindowEx function. If the window was active before the call, the return value is nonzero.
If the window was not active before the call, the return value is zero.
Typically, you flash a window to inform the user that the window requires attention but does not currently have the keyboard focus. When a window flashes, it appears to change from inactive to active status. An inactive caption bar changes to an active caption bar; an active caption bar changes to an inactive caption bar.
