Steps to Reproduce Behavior

  1. Create a new Standard EXE Project.
  2. Place two ListView controls on the form (ListView1 and ListView2).
  3. Place the following code into the General Declarations section of the form:

        Private Sub Form_Load()
            Dim Li As ListItem
            Set Li = ListView1.ListItems.Add(, , "hello")
            Set Li = ListView1.ListItems.Add(, , "hello2")
            Set Li = ListView1.ListItems.Add(, , "hello3")
        End Sub
    
        Private Sub ListView1_MouseDown(Button As Integer, Shift As Integer, _
        x As Single, y As Single)
           Set ListView1.SelectedItem = ListView1.HitTest(x, y)
           ' In the following line any ICO file will do
           ListView1.DragIcon = LoadPicture _
           ("C:\program files\microsoft visual basic\samples\calc\calc.ico")
           ListView1.Drag vbBeginDrag
        End Sub
    
        Private Sub ListView2_DragDrop(Source As Control, x As Single, _
        y As Single)
           MsgBox "Hello"
           Dim li2 As ListItem
           Set li2 = ListView2.ListItems.Add(, , Source.SelectedItem.Text)
        End Sub
    
                            
  4. Run the form and attempt to drag "hello" from ListView1 to ListView2. Note that the drag icon disappears when the item is moved.
