Scroll Scroll

[hoa01206]

If you have two controls and each one has a vertical bar. Is there a way that when you scroll down or up on one the second follow the same trend.

Please, let me know if I can connect between the two scroll bars.

Thanks

'this code will let you grab the scroll bar position.
'I did not try but I think you can set the second scroll bar tot the same position

Will this also work for a scroll bar that comes with the MSFlexGrid Control?

This is a great sample, but does not work on the Properties dialog box from Device Manager. Does anyone know why? It worked with other windows. I also have the correct hWnd value.....
