FIX: TreeView.Visible = False at Design-Time Causes Problems

MORE INFORMATION

Steps to Reproduce

1. Start Visual Basic 4.0. Form1 is created by default.
2. Add a single TreeView control and two command buttons to Form1.
3. Set this property of TreeView1:

   Visible: False

4. Add this code to Form1:

      Private Sub Form_Load()
         Dim nodX As Node  ' Create a tree.
         Set nodX = TreeView1.Nodes.Add(,,"r", "Root")
         Set nodX = TreeView1.Nodes.Add(,,"p", "Parent")
      End Sub
   
      Private Sub Command1_Click()
         TreeView1.Visible = True
         Debug.Print TreeView1.Nodes.Count
      End Sub
   
      Private Sub Command2_Click()
         TreeView1.Nodes.Clear
         Debug.Print TreeView1.Nodes.Count
      End Sub
   						

5. Press F5 or select Start from the Run menu to start the application. Press the first command button--although the count property will say two, no nodes will be visible in the control. To demonstrate another oddity, stop and restart and then press Command2. The Clear method should have removed all nodes, but the Count property still returns 2.
