Scrollbalken anpassen

[candida]

hallo zusammen,

ich habe eine textbox, die den text extern einläd.
da der text austauschabr ist, wird auch die textbox je nach inhalt unterschiedlich groß. nun soll sich der balken natürlich der box anpassen. ich habe bereits einen, der nur dies allerdings nicht tut.
wenn das hilft, poste ich hier mal das as rein, was dahinter liegt.

es dankt nochmal: candida
