You can use CListCtrl::GetFirstSelectedItemPosition()

You have to use GetNextSelectedItem(Pos)to get the item index, this will return the item index as 'int', use this 'int' value in GetItemText() and assign 0(zero) to subitem if you are not using the ListCtrl in Report View

It sounds as though you are responding to the LVN_ITEMCHANGED message. When you select an item, more than one item has changed at that point. Study the NMLISTVIEW structure for details.

If you are using MFC, use the CListCtrl::GetNextItem(-1, LVNI_SELECTED) method.

It's considered good practice to read the documentation to confirm/verify what you read here.

We have a custom control ( similar to tree control ) in which we can insert columns. In one of the columns i want to have check boxes.

I need some pointers as in how to do it as the original developer of the control is not with us.

m_Image.BitBlt(dc.m_hDC,CRect(0,0,800,600),CPoint(0,0));<br />
