Oh One more thing, when you are unselecting an item but you still want the
focus rect around the item then you might want to do this instead
if (....)


   //disable the item but still draw the focus rect

Here is how I would do it. I would catch the LVN_ITEMCHANGED message for
the list ctrl and check to see if the item is being selected. If it is
and it is disabled then I would simply unselected it.

//every other item is disabled!
BOOL CMyListCtrl::IsItemDisabled(UINT ItemID)
  return ItemID % 2 != 0;

void CMyListCtrl::OnLvnItemchanged(NMHDR *pNMHDR, LRESULT *pResult)
   //if item is being selected and is diabled
  if (IsItemDisabled(pNMLV->iItem) && (pNMLV->uNewState & LVIS_SELECTED)
       //unselect it!
  *pResult = 0;

Hello everybody.
I have a CListCtrl derived class wich is also owner draw. Now I need to
disable selecting items. So user should be able to see the list and be
able to scroll it and everything. But selecting items should be
disabled. I wrote a handle for OnLButtonDown which give me an
opportunity to handle mouse button clicking and so user can't select the
item by mouse. But it is still possible by arrows. I tried to handle
VKeyToItem but it aseems never get called. So in my case how can I
disable selecting items by arrows also. Or is there any better way to do
that all together?
PS: I was looking for some properties for a CListCtrl but didn't find
anything useful.
