I'm building a window form with VB.net. The purpose of this app is to show
some legal terms in a text box and users will accept or deny the terms.
Similar to the one when installing software. There is a feature I want to
implement but still out of luck after a day of researching and testing.

The text box is a not large enough to display the pages long text. So I
enabled the vertical scrollbar. How do I know if the scrollbar is moved to
the bottom of the textbox so it triggers the enabling of accept/cancel
buttons? The control does not give me any coordinates, max, min, etc values
or other events to use.

THanks

Hello J,

I agree with Herfried in both respects. While technically possible, this
is a terrible idea. Windows 2000 tried to do this with their OS installer.
All it did was make people hold down the PgDn button for a second or two
before hitting the key to proceed. There is simply NO practical way of forcing
someone to read a EULA. And why would you want to? Are you a control freak?
A EULA is there to cover yer ass. Who cares if the user read it as long
as it was presented to them.

Maybe this is possible by overriding the textbox' 'WndProc' method and
handling 'WM_VSCROLL', and then using 'GetScrollInfo' to determine the
current scroll position. However, I don't think that it is very
user-friendly to let users scroll down the textbox in order to enable
buttons.
