    This is the code for DragAndDropping on your form:
    Code:
    Private Sub Form_OLEDragDrop(Data As DataObject, Effect As Long, Button As Integer, Shift As Integer, X As Single, Y As Single)
    Data.Files (1)
    End Sub
    Data.Files(1) would be your icon, so from there :

    if extension = .pif or .lnk it's a shortcut...

    Is this what you want?

    Code:
    Private Sub Form_Load()
    Me.OLEDropMode = 1
    End Sub
    
    Private Sub Form_OLEDragDrop(Data As DataObject, Effect As Long, Button As Integer, Shift As Integer, X As Single, Y As Single)
    If Data.GetFormat(vbCFFiles) Then MsgBox Data.Files(1)
    End Sub
