When I needed a similar effect I used Tim Hockin's Scrollbar class (See Classes-VCX in the Files section). Worked beautifully, and I even changed som of it to add resize capability to his controls.

>I've created a container and dropped 15 checkboxes inside of it. I only want the contianer to show 5 of the
>checkboxes at a time, so I've changed the size of the container and added the Microsoft Flatscrollbar
>control from the ActiveX control options into the container. Since this is my first time to do this, I have no
>idea how to actually make the scrollbar scroll through the checkboxes. Any and all help would be greatly
>appreciated.
