vb.net 窗体布局的问题

1.先在窗体放置两个pane，pane1的Dock属性是Left，pane2是fill

目前创新互联已为成百上千家的企业提供了网站建设、域名、网页空间、绵阳服务器托管、企业网站设计、石楼网站维护等服务，公司将坚持客户导向、应用为本的策略，正道将秉承"和谐、参与、激情"的文化，与客户和合作伙伴齐心协力一起成长，共同发展。

2.再添加两个pane，分别为pane3，pane4，把她们添加到pane2里面

3.再添加两个button，放置到pane1里面

4.往pane3和pane4中分别放点不同的东西

5.然后button的事件是：

private void button1_Click(object sender, EventArgs e)

{

this.panel3.Visible = true;

this.panel4.Visible = false;

}

private void button2_Click(object sender, EventArgs e)

{

this.panel3.Visible = false;

this.panel4.Visible = true;

}

大概都是这么实现的，具体的效果还需要丰富

我以前也研究过vista优化大师的效果

也仿照出来了，如果你需要源代码，可以写上你的邮箱，我给你发过去

vb.net xml 和treeview

你的xml文字有错误,正确的如下: ?xml version="1.0"? grouplist group name="1" server name="1.1"/ server name="2.2"/ /group group name="2" server name="2.1"/ server name="2.2"/ /group /grouplist 以下是在vs2008下调试成功 Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim tvw As TreeView Dim x As New Xml.XmlDocument Dim nd As Xml.XmlNode Dim pcnd As TreeNode Dim I As Integer Dim II As Integer tvw = New TreeView tvw.Parent = Me tvw.SetBounds(10, 10, 300, 300) x.Load("该处为xml文件路径") '如 C:\\abc.xml For I = 1 To x.DocumentElement.ChildNodes.Count nd = x.DocumentElement.ChildNodes(I - 1) pcnd = tvw.Nodes.Add("G" I.ToString, nd.Attributes(0).Value) For II = 1 To nd.ChildNodes.Count pcnd.Nodes.Add(nd.ChildNodes(II - 1).Attributes(0).Value) Next pcnd.Expand() Next End Sub End Class

vb.net操作xml数据库(急)

使用System.XML

Imports Microsoft.VisualBasic

Imports System.Xml

namespace HowTo.Samples.XML

public class WriteXmlFileSample

private const document as string = "newbooks.xml"

shared sub Main()

myWriteXmlFileSample.Run(document)

end sub

public sub Run(args As String)

Dim myXmlTextReader as XmlTextReader = nothing

Dim myXmlTextWriter as XmlTextWriter = nothing

try

myXmlTextWriter = new XmlTextWriter (args, nothing)

myXmlTextWriter.Formatting = System.Xml.Formatting.Indented

myXmlTextWriter.WriteStartDocument(false)

myXmlTextWriter.WriteDocType("bookstore", nothing, "books.dtd", nothing)

myXmlTextWriter.WriteComment("此文件表示书店库存数据库的另一个片断")

myXmlTextWriter.WriteStartElement("bookstore")

myXmlTextWriter.WriteStartElement("book", nothing)

myXmlTextWriter.WriteAttributeString("genre","autobiography")

myXmlTextWriter.WriteAttributeString("publicationdate","1979")

myXmlTextWriter.WriteAttributeString("ISBN","0-7356-0562-9")

myXmlTextWriter.WriteElementString("title", nothing, "The Autobiography of Mark Twain")

myXmlTextWriter.WriteEndElement()

myXmlTextWriter.WriteElementString("price", "7.99")

vb.net中怎么创建xml文件并写数据

DataSet 和 DataTable都有现成的方法：WriteXml

DataTable tb = this.dataGridView1.DataSource as DataTable;

if(tb != null)

{

tb.WriteXml(@"C:\table.xml",true);

return;

}

DataView dv = this.dataGridView1.DataSource as DataView;

if(dv != null)

{

dv.Table.WriteXml(@"C:\table.xml",true);

return;

}

IList list = this.dataGridView1.DataSource as IList;

if(list != null)

{

//to do,如果是IList,就要你自己想办法导出了

//XmlDocument or XmlWriter都可以考虑

}

怎么用vb 修改 xml ?

有多种方法.

如果是vb.net，则其本身就有xml编辑支持，具有xml系统类，可以直接调用，再配合了listview来进行可视化处理。

如果是vb 6.0

则可以借助外部的控件，或者别人做好的控件。

其实xml也是一种可编辑的纯文本格式。

你可以在vb里用richtextbox的load方法加载，然后自己用find方法分析，在列出树形图。

VB.NET 的TreeView控件连接XML文件

把XML看成一棵树吧..用xmldocument操作,,,这里有参考的

有点难度噢...
