Set nodx = TreeView1.Nodes.Add("zfwife", tvwChild, "lp1", "大老婆")

Set nodx = TreeView1.Nodes.Add("zfwife", tvwChild, "lp2", "二老婆")

Set nodx = TreeView1.Nodes.Add("zfwife", tvwChild, "lp5", "五老婆")

Set nodx = TreeView1.Nodes.Add("zflover", tvwChild, "qr1", "1号情人")

Set nodx = TreeView1.Nodes.Add("zflover", tvwChild, "qr2", "2号情人")

Set nodx = TreeView1.Nodes.Add("zflover", tvwChild, "qr3", "3号情人")

Set nodx = TreeView1.Nodes.Add("zffriend", tvwChild, "py1", "张三")

Set nodx = TreeView1.Nodes.Add("zffriend", tvwChild, "py2", "李四")

Set nodx = TreeView1.Nodes.Add("zffriend", tvwChild, "py3", "王麻子")

Set nodx = TreeView1.Nodes.Add("py1", tvwChild, "pylp1", "张三的老婆")

Set nodx = TreeView1.Nodes.Add("py1", tvwChild, "pylp2", "张三的孩子")

nodx.EnsureVisible

End Sub

'删除代码

Private Sub Command2_Click()

MsgBox ("将要删除" &TreeView1.SelectedItem.Text)

TreeView1.Nodes.Remove (TreeView1.SelectedItem.Index)

End Sub

拖一个ContextMenuStrip控件到界面上，起个名字cms，设置菜单后，并双击实现菜单的点击事件！！

最后设置treeview的ContextMenuStrip的属性绑定cms就可以了！！

先在窗体上添加菜单(如:mnucd)，然后在treeview控件的MouseDown事件中输入：

If Button = 2 Then PopupMenu mnucd

即可
