主题：[求助]树节点特殊显示

 哈哈，第一个问题，终于是模拟成功了。如下。

Dim tree As System.Windows.Forms.TreeView = mytree.BaseControl

For i As Integer = tree.Controls.Count - 1 To 0 Step -1
    If tree.Controls(i).Name = "SelectLab" Then
        tree.Controls.RemoveAt(i)
    End If
Next

Dim selCon As  System.Windows.Forms.Control = tree.Controls("SelectLab")
Dim label As New System.Windows.Forms.Label
label.Name = "SelectLab"
label.AutoSize = False
label.BackColor = Color.Red
label.ForeColor = e.Node.ForeColor
label.Font = tree.Font
mytree.BaseControl.Controls.Add(label)
selCon = Label
Dim node As System.Windows.Forms.TreeNode = tree.SelectedNode
selCon.Size = new Size(node.Bounds.Width, node.Bounds.Height)
selCon.Location = new Point(node.Bounds.X, node.Bounds.Y)
selCon.Text = e.Node.Text

 第二个问题，比较简单，不是有MainTableChange事件么？项目属性那里。

 然后设置 StatusBar.Message1 = ""
