Scroll bars
-
I have created a window inherited from CFrameWnd using the create function and I use WS_VSCROLL to stick a vertical scroll bar on the right edge. I want to be able to code the movements of the user clicking on the scroll bar etc and the movement shown withing the bar, my problem is what is the scrollbar called so I can call member functions such as GetScrollPos() etc. I have tried the method OnVScroll and used the pScrollBar parameter but this only comes up with a run time error as if it were null which I think it is. cheers in advance Nick

The pScrollBar is null if the scrollbar is not a control but belongs to a window. Simply use the CWnd::GetScrollPos member function.
void CMainFrame::SomeFunc()
{
...
int pos = GetScrollPos(SB_VERT);
...
