Question : how to know the name of the selected pushpin ?

Answer : in the _SelectionChange event of your
MapPoint control, write :

Code:
    If TypeOf ctrlMAPPOINT.ActiveMap.Selection Is Pushpin Then

        Dim PP As MapPoint.Pushpin
        Set PP = pNewSelection
        
        MsgBox PP.Name
        
        ' Or do something different
        
    End If
Thanks for the help I received !
