Unhandled exception using CXTListView

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   In a simple, from CXTListView derived, class I have this update function:
CXTListCtrl& lc = (CXTListCtrl&)GetListCtrl();
lc.DeleteAllItems();
for (int i = 0; i < 10; i++)
{
  int nItem = lc.InsertItem(lc.GetItemCount(), "A");
  lc.SetItemData(nItem, (DWORD_PTR)123456L);
  lc.SetItemText(nItem, 1, "B");
  lc.SetItemText(nItem, 2, "C");
}
lc.AutoSizeColumn(-1);
If I comment out the line with AutoSizeColumn(), everything works OK. If I uncomment the line, I get an "Unhandled exception at 0x00000000 in Application.exe: 0xC0000005: Access violation reading location 0x000000.

Can anyone help me with this? Thx!

	Hi, You can 't use such line: CXTListCtrl& lc = (CXTListCtrl&)GetListCtrl(); GetListCtrl returns always CListCtrl& - you can't cast it to CXTListCtrl& if you have CXTListView just call directly: AutoSizeColumn(-1);
