    Webcam Bilder in Galerie

    Hallo Liebe Leute,
    Ich komme direkt zum Problem, da ich wenn ich erlig bin keine Ahnung von Schnittstellen Prog. habe.
    Habe im Netz einen Code gefunden mit dem ich via Webcam, Bilder machen kann und speichere.
    Nun zu meiner Frage, wer ist so nett und kann mir sagen wie ich das Livebild so groß bekomme wie meine Pic Box???
    Eine direkte Lösung wäre super, da ich wie gesagt absolut keine Ahnung habe.
    Meine Webcam ist eine Microsoft mit 1080p.
