    @Marmelade Entweder Du schreibst diesen Code in die Form_Load oder so:
    Falls Du diesen Code kopierst, achte auf die C&P-Bremse.
    Jede einzelne Zeile Deines Programms, die Du nicht explizit getestet hast, ist falsch :!:

    @Marmelade Dies funktioniert bei mir:

    C#-Quellcode

    1. public Form1()
    2. {
    3. InitializeComponent();
    4. this.KeyPreview = true;
    5. }

    @Marmelade Sieh Dir mal Deine Prozedur InitializeComponent() an:
