CListCtrl funny stuff (bug or incorrect use?)

[Andrew Kaspick]

Has anybody seen the following problem before and if so do you know how to
fix it?

I've actually got this in a CListView, but I can't see how that would
matter.

This is my problem....
I fill my list box up so that a scroll bar appears and then I scroll to the
bottom and then resize the list control so that I can see every item. But
when I do this the very top item jumps down one position leaving an empty
space at the top.

It seems to occur in the code I use when I resize, if I comment out the
SetColumnWidth calls everything seems to work fine.

void CTaskDebuggerView::OnSize(UINT nType, int cx, int cy)
{
CListCtrl& ListCtrl = GetListCtrl();

ListCtrl.SetColumnWidth(0, cx * 0.3);
ListCtrl.SetColumnWidth(1, cx * 0.2);
ListCtrl.SetColumnWidth(2, cx * 0.5);

CListView::OnSize(nType, cx, cy);
}

Thanks for the help,
Andrew

Andrew,

I think I've seen others mention similar problems. Do you have an
up-to-date version of Comctl32.dll?

See if updating the DLL fixes the problem or not.

The last record I have, the updated DLL was available at:

Have you tried this?

void CTaskDebuggerView::OnSize(UINT nType, int cx, int cy)
{

CListView::OnSize(nType, cx, cy);

CListCtrl& ListCtrl = GetListCtrl();

ListCtrl.SetColumnWidth(0, cx * 0.3);
ListCtrl.SetColumnWidth(1, cx * 0.2);
ListCtrl.SetColumnWidth(2, cx * 0.5);
}
