Hi,
Thinking out loud here. You've got two listboxes filled with data. You move the vertical scrollbar
on the lefthand box, and the vertical scrollbar moves in the righthand box, in sync
Maybe the same with the horizontal scrollbars
Is this possible? Make my day!

Blimey!
What can I say? Larry comes up with the goods again...

This allows sync'd scrolling of two listboxes from either listbox.(requires subclassing the LBs)
Also selects matching line in both LB's from either LB.

Larry,
Is there a way of using this technique with dual Listviews, as well?

When I first looked at it for a listview I thought it was going to be a breeze to convert the listbox version, especially when I found that listviews have a LVM_GETTOPINDEX just like the listbox's LBM_GETTOPINDEX. ;D ;D ;D
Then :o ??? :o ::) :'(
I discovered that listviews don't have a LVM_SETTOPINDEX just like the listbox's LBM_SETTOPINDEX.
So, I had to to do some looking and heavy duty head scratching.
The result is attached. Because there are fundmental differences between how listviews and listboxes work there are some differences.
The listview version does sync the 2 LVs when the scroll bars are used just like the LBs.
However, if you use the arrow keys they will not be in sync.
Also, when you select in one it will automaticly select the same line in the other but the selection in the 2 LVs will be different colors (one has focus and the other doesn't)
But maybe it will get you where you want to go.

With all the messages that are available to richedits I would have to say yes(for the most part)
It would really come down to the specifics of what you are trying to do(and I do mean SPECIFIC).
