Witam, potrzebuje połączyć 2 kody ze sobą....Jeden to ten:
[DllImport("user32.dll")]
private static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
public IntPtr GetHandleWindow(string title)
{
return FindWindow(null, title);
}
a drugi służy do robienia zrzutów ekranu (zależy mi konkretnie na tym kodzie a nie na innym, bo ten działa u mnie idealnie).
Czy da się wykorzystując poniższy kod wykonać zrzut ekranu konkretnego okna aplikacji , zamiast tego co obecnie on robi ? Używając kodu FindWindow ?
