Date: 2008jul17 Platform: win32 Language: C/C++ Q. How can I flash a Window to indicate an error? A. Use FlashWindow() or FlashWindowEx() like this:

BOOL Flash(const HWND hwnd) { FLASHWINFO info; ZeroMemory(&info, sizeof(info)); info.cbSize = sizeof(info); info.hwnd = hwnd; info.dwFlags = FLASHW_CAPTION | FLASHW_TRAY | FLASHW_TIMERNOFG; info.uCount = UINT_MAX; info.dwTimeout = 0; return ::FlashWindowEx(&info); }
