a question on sortign out vertical scrolling

[bryce burrows]

Hi
I have an image i am trying to view correctly in my csrollview dreived class...
I place the image in the view by using StretchDIBits and its showing up just fine

its quite long and goes off the bottom to where you are suposed to scroll to..so no problems there

But i dont know how to make the vertical scrolling work correctly and was wondering
what exact steps do i need to do to make sure that the vertical scrolling work correctly?

do i need to worry about screen units?
what do i need to set the scroll sizes to and how do i figure it out (if say my image is a matrix 256x1024 greyscale)
?
I would appreciate any help you could give me as i am finding this quite difficult

thank you

Regards


Bryce
