Keine optimale Lösung, das Label scrollt nach rechts, anstatt in die Leserichtung, und das Label klebt ganz nach oben in der Form, und was hat die Variable i da zu suchen?

[code]
private void t1_Tick(object sender, EventArgs e)
{
if (label1.Location.X == -label1.Size.Width)
label1.Location = new Point(this.Size.Width, label1.Location.Y);
label1.Location = new Point(label1.Location.X-1, label1.Location.Y);
}
[/code]
