Nick,
You could put this in a command button.
Code:
Dim objmap As MapPointctl.Map
Dim objPushpin As MapPointCtl.Pushpin
Set objmap = MapPointControl1.ActiveMap
'Make sure the item selected on the map is a pushpin
If TypeOf objmap.Selection Is Pushpin Then
Set objPushpin = MapPointControl1.Selection
'Do Something
msgbox objpushpin.name
End If
