Control: Microsoft ListView Control, Version 6.

Code Being used:
For i = 1 To openrec.RecordCount
lstitem = AxListView1.ListItems.Add()
lstitem.Text = openrec.Fields("field1").Value
lstitem.SubItems(1) = openrec.Fields("field1").Value
lstitem.SubItems(2) = openrec.Fields("field2").Value
openrec.MoveNext()
Next

========================================================

Anyone know why I am getting this error? I am trying to load a listview with information from my database.

Is lstitem declared as a ListViewItem?

I only ask as I think the problem is coming from where you're trying to assign it as an added listitem, and it can't convert between your control's class MSComctlLib.ListItemClass and what you've got lstitem declared as probably System.Windows.Forms.ListViewItem.

What version of Visual Studio are you using? This is because (and I can't vouch for versions earlier than 2005) that's not the listview control I have available (and I seem to remember it was available in Windows Common Controls through VB6?)

I see it is the same listview control available in VB6, accessible via the COM Components tab of the Choose Toolbox Items dialog.

Is there a particular reason you chose to use this version of the listview?

No particular reason why i chose this version. I think I may have had too many references selected, so I deleted/unselected some of them.

I then was able to figure out my issue using the listview (most recent version - not vb6 version). I will post how i resolved it later.

Thank you for your reply though HarleyQuinn. Its appreciated.
