Dim httpURL As New System.Uri(url)

httpReq = CType(WebRequest.Create(httpURL), HttpWebRequest)

httpReq.Method = "GET"

httpResp = CType(httpReq.GetResponse(), HttpWebResponse)

httpReq.KeepAlive = False ' 获取或设置一个值vb.net获取url，该值指示是否与

Internet资源建立持久连接。

Q3: vb.net怎么实现点击下载，获取文件路径并下载

下载，直接通过url读取文件，然后Response.OutputStream.Write()数据

下面提供个下载的静态方法，是C#的，供参考：

/// summary

/// 下载文件

/// /summary

/// param name="fileName"下载的文件名称（包括扩展名）/param

/// param name="filePath"下载文件的绝对路径/param

public static void DownFile(string fileName, string filePath)

{

    //打开要下载的文件，并把该文件存放在FileStream中                

    System.IO.FileStream Reader = System.IO.File.OpenRead(filePath);

    //文件传送的剩余字节数：初始值为文件的总大小                

    long Length = Reader.Length;

    HttpContext.Current.Response.Buffer = false;

    HttpContext.Current.Response.AddHeader("Connection", "Keep-Alive");

    HttpContext.Current.Response.ContentType = "application/octet-stream";

    HttpContext.Current.Response.Charset = "utf-8";

    HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment; filename=" + System.Web.HttpUtility.UrlEncode(fileName));

    HttpContext.Current.Response.AddHeader("Content-Length", Length.ToString());

    byte[] Buffer = new Byte[10000];//存放欲发送数据的缓冲区                

    int ByteToRead; //每次实际读取的字节数               

    while (Length  0)

    {    

 //剩余字节数不为零，继续传送                    

        if (HttpContext.Current.Response.IsClientConnected)

        {    

//客户端浏览器还打开着，继续传送                        

            ByteToRead = Reader.Read(Buffer, 0, 10000);                   //往缓冲区读入数据                        

            HttpContext.Current.Response.OutputStream.Write(Buffer, 0, ByteToRead);    

//把缓冲区的数据写入客户端浏览器                        

            HttpContext.Current.Response.Flush(); //立即写入客户端                        

            Length -= ByteToRead;//剩余字节数减少                            }

        else

        {                         

//客户端浏览器已经断开，阻止继续循环                        

            Length = -1;

        }

    }                //关闭该文件               

    Reader.Close();

}

Q5: 用VB提取网页中的链接地址

获得网页中vb.net获取url的超链接网址对一些网络编程很有用处,很多朋友都不会用,今天vb.net获取url我就交给大家怎么才能在VB6.0中实现这个功能,首先新建一个工程,加入webbrowser和scriptlet控件(引用部件Microsoft HTMl object Library添加一个Listbox控件(用于存放读出vb.net获取url的网址)命名为(listurl),个textbox()控件用于打开网址命名为txtsearchOption ExplicitDim UrlNow As IHTMLDocument2Private Sub CmdGeturl_Click() 'WebBrowser1.Stop 'Dim UrlNow On Error GoTo errordes Set UrlNow = WebBrowser1.Document If UrlNow Is Nothing Then MsgBox "当前页面没有链接", vbInformation, "注意" Else Dim UrlIndex As Long For UrlIndex = 0 To UrlNow.links.length - 1 ListUrl.AddItem UrlNow.links(UrlIndex) Next UrlIndex End If Exit Suberrordes: MsgBox "未知错误", vbCritical, "错误" End SubPrivate Sub Cmdstart_Click() WebBrowser1.Navigate2 txtSearch.Text End Sub这个就完具体请看vb.net获取url我vb.net获取url的博客:
