Re: Owner Data ListView Ctrl failing to insert column in Vista

Thank you for the suggestion.  I have spent hours trying varying combinations. Started with the simplest list control (which shows columns in Vista as well as XP) and slowly added styles (no headers, owner data etc. ) to see when it fails.  It certainly appears to be a bug and is consistent when I try and create the control (though I confirm that after the 'create' the requested styles are the same both in XP and Vista)

Worked around this finally  - have a dialog as the view for the mainframe and the control in the dialog where styles are set in the resource. This means extra work in terms of routing some messages from the mainframe but both Vista and XP show column style listview control

If I knew how to write this as a bug /support request - I would.
