[urga]

das form hat 3 elemente: textBox1, label1, timer1.
gesteuert werden die zeiten über

tickerCharMS: ms für die einzelnden buchstaben
tickerNewLineMS: ms die für eine newline gewartet werden.

tickerCharMS soll sich ja pro zeile um 1 erhöhen.
um einen effekt zu bemerken habe ich den um jeweils 50 erhöht.
