Problem with FindItem in CListView

I am trying to use the FindItem function to determine which item is currently selected but it seems to return -1 (error) no matter what information I enter. e.g.

      LV_FINDINFO      lvf;
      int nFound;
      lvf.flags = LVFI_PARAM;
      lvf.lParam = LVIS_SELECTED;
      CListCtrl& theCtrl = GetListCtrl();
      nFound = theCtrl.FindItem(&lvf,-1);

I've tried all the other lParam options to no avail. Anybody   know the answer?

Unfortunately, the LV_FINDINFO does not work that way. The LVFI_PARAM will find the first item whose ItemData (which is set by SetItemData) is equal to LV_FINDINFO.lParam.

If you want to find the first or any items that is selected, you will need to use GetItemState() on each item and check if the LVIS_SELECTED flag is turned on.

  for (int i = 0; i < GetItemCount(); i++)
  {
    if (GetItemState(i, LVIS_SELECTED) == LVIS_SELECTED)
    {
       // Item is selected
    }
  }
