Scroll position jumps to 0

General

Hey,

Whenever I use the Scroll method on my canvas it always seems to jump back to 0 instantly. How could this be? I am changing the scroll value with a scrollbar in the ValueChanged event.

Thanks

Let me just pull out my psychic powers here.

Reading your code, reading your code, AH! It seems to be line 275.

In value changed event:

[code] // Calculate the delta that the scrollbar was
// moved and scroll the canvas accordingly.

Dim delta As Integer

delta = mVerticalScrollBarLast - Me.Value

delta = (delta / Me.Maximum) * Code.Height

mYScroll = mYScroll + delta

Code.Scroll(0, delta)

mVerticalScrollBarLast = Me.Value[/code]

Thanks

Are you scrolling horizontally or vertically?
Because one line you’re comparing the delta to the height, and the scroll line you’re scrolling horizontally.

Edit: or I flunked maths. I thought you graph up, and then over? Oh well. Shutting up now.

Scrolling vertically.

How do you increase the scroll area?
