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
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" />

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
9 ' 做准备工作
10 doc.Load(strPathConfig)
11 rootnode = doc.DocumentElement
12 intNum = rootnode.ChildNodes.Count - 1
13 '
14 LoadConfig()
15 End Sub
16 ' 添加到CheckedListBox
17
Function LoadConfig() Function LoadConfig()
18 Dim i As Int16
19 For i = 0 To intNum
20 CheckedListBox1.Items.Add(rootnode.ChildNodes(i).Attributes( 0 ).Value, CType (rootnode.ChildNodes(i).Attributes( 1 ).Value, Boolean ))
21 Next
22 End Function
23 ' 确定,然后写入XML
24
Function WriteConfig() Function WriteConfig()
25 Dim i As Int16
26 Dim str As String
27 For i = 0 To intNum
28 rootnode.ChildNodes(i).Attributes( 1 ).Value = CheckedListBox1.GetItemChecked(i).ToString
29 Next
30 doc.Save(strPathConfig)
31 End Function
32
33
Private Sub Button2_Click() Sub Button2_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
34 ' 需要清除CheckedListBox内的Items
35 CheckedListBox1.Items.Clear()
36 LoadConfig()
37 End Sub
