Dim i As Integer Dim c As New Collection For i = 1 To Me.TreeView1.Nodes.Count If Me.TreeView1.Nodes(i).Children = 0 Then c.Add i Next For i = c.Count To 1 Step -1 Me.TreeView1.Nodes.Remove c(i) Next

Private Sub Command1_Click() num = 0 For i = 1 To TreeView1.Nodes.Count If TreeView1.Nodes(i).Children > 0 Then num = num + 1 End If Next MsgBox num End Sub
