>I want to display the "DisplayMember" instead of the "ValueMember"<

Yes, of course, you've already done that by setting the .DisplayMember of the DataSource. But I'm talking about this:

cboActivity.DataBindings.Add(New Binding("SelectedValue", regDV, "activities"))

This has nothing to do with what gets displayed ... this means that when the user selects from the Combo, the .SelectedValue (meaning the what you have in the .ValueMember) gets put in the "activities" column of the regDV DataView. That is what you wanted, isn't it?
