简单的一个应用例子 ，只是简单的操作XML文件，在实际的应用上可以先建一个配置类保存状态。

XML文件的结构：

1 <?xml version="1.0" encoding="utf-8" ?>
2  <config>
3  <Function Name="a" Checked="false" />
4  <Function Name="b" Checked="false" />
5  <Function Name="c" Checked="false" />
6  <Function Name="d" Checked="false" />
7  </config>

具体的程序：需要一个CheckedListBox,两个Button

 1    Public doc As New XmlDocument
2    Public rootnode As XmlElement
3    Public strPathConfig As String = Application.StartupPath & "\config.xml"
4    Public intNum As Int16
5    Private Sub Button1_Click()Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
6        WriteConfig()
7    End Sub
8    Private Sub Form1_Load()Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
