Windows API Guide: FlashWindow Function Platforms: Win 32s, Win 95/98, Win NT FlashWindow flashes a window one step. Flashing is where the title bar of the window is switched from an active to inactive look (or vice versa) to get the user's attention. Normally this is done multiple times, instead of just once. When you are done flashing, be sure to call the function again, this time with bInvert set to 0. The function returns 0 if the window's look was inactive before flashing, or 1 if its look was active. hwndThe handle of the window to flash one step. bInvertSpecifies how to flash. If non-zero, switches the title bar from an active to inactive look (or vice versa). If zero, restores the window to its normal look.
