Hi jur9103,

To find out when the selection of the CListCtrl has changed, you have to trap the LVN_ITEMCHANGED message.

To find out how many items in the CListCtrl have been selected call the member function:

int SelCount = MyLstCtrl.GetSelectedCount();

To get each selected item do (for Multi-Sel ListCtrl Only):

POSITION pos = MyLstCtrl.GetFirstSelectedItemPosition();

if(pos == NULL)

int ListItemIdx;
CString TmpStr;

  // This will give you the index of one of the selected items
  ListItemIdx = MyLstCtrl.GetNextSelectedItem(pos);

// First parameter is the item index and the second parameter is the subitem index
TmpStr = MyLstCtrl.GetItemText(ListItemIdx, 0);

while(pos != NULL);

for a Single Selection ListCtrl do:

// This will return the index of the next selected item
// -1 means find the first selected item, if > -1 then this will start the search from the given index
int SelIdx = MyLstCtrl.GetNextItem(-1, LVNI_SELECTED);


int SelCount = MyLstCtrl.GetSelectedCount();

This will word for both single selection ListCtrl and Multi-Selection ListCtrl.

I hope this help.
