Storing a HANDLE in a CListCtrl

[gstercken]

Three columns....right? I have three different headers. One that says IP address, one that says Port and a third that says ID.

Ok, so that are columns. Yes, columns are vertical, rows horizontal...

So with the ID I can add the handle to the LPARAM value.

Note that in a list control, the item data is always associated with the entire row, not with the sub items (the additional columns). So you would actually not assign the handle to "the ID", but to the entire item (the row).
