Hey Zusammen!
Ich arbeite im Moment an einem Programm dass das Bild der Webcam in einer PictureBox anzeigt und es speichern soll.
Mit Hilfe der avicap32.dll hab ich's geschafft dass das Bild meiner Webcam angezeigt wird aber hat jemand eine Idee wie Ich dass in eine Datei speichern könnte?
Hier ist mein Code:
