获取webbrowser控件 网页的源码

我在网上找到使用rft控件保存webbrowse文本   txtHtml是RichTextBox
txtHTML.Text = WebBrowser1.document.body.innerText
'flag ：rsftext 保存为txt文件，strtmp文件路径
txtHTML.saveFile strtmp, rtfText

将其name属性设置为web

Private Sub Command1_Click()
     web.Navigate "www.google.com"
End Sub

Private Sub web_DocumentComplete(ByVal pDisp As Object, URL As Variant)
Set doc = web.Document
For Each i In doc.All
     msgbox typename(i)
     Text1.Text = Text1.text & vbclrf & i.innertext
Next
End sub

转载

'引用 Microsoft HTML Object Library

     Dim oDoc As HTMLDocument
     Dim oElement As Object
     Dim oTxtRgn As Object
     Dim sSelectedText As String
    
     Set oDoc = WebBrowser1.Document'获得文档对象
     Set oElement = oDoc.getElementById("T1")'获得ID="T1"的对象
     Set oTxtRgn = oDoc.selection.createRange'获得文档当前正选择的区域对象
   
     sSelectedText = oTxtRgn.Text'选择区域文本赋值

     oElement.Focus'"T1"对象获得焦点

     oElement.Select'全选对象"T1"

     Debug.Print "你选择了文本：" & sSelectedText

上面这段儿还附送了其他功能，呵呵。精简一下是这样：
     Dim oDoc As Object
     Dim oTxtRgn As Object
     Dim sSelectedHTML As String
    
     Set oDoc = WebBrowser1.Document '获得文档对象
     Set oTxtRgn = oDoc.selection.createRange '获得文档当前正选择的区域对象
   
     sSelectedHTML = oTxtRgn.htmlText '选择区域文本赋值

     Text1.Text=sSelectedHTML '文本框显示抓取得HTML源码
     ......'或者继续分析源码

我用WebBrowser取得网页源码，直接运行正常，但在编译后出错
Private Sub Command1_Click()
WebBrowser1.Navigate "http://www.sdqx.gov.cn/sdcity.php"
End Sub

Private Sub WebBrowser1_DownloadComplete()
'页面下载完毕
Dim doc, objhtml
Set doc = WebBrowser1.Document

Set objhtml = doc.body.createtextrange()
If Not IsNull(objhtml) Then
Text1.Text = objhtml.htmltext
End If

End Sub

我用WebBrowser取得网页源码，直接运行正常，但在编译后出错

提示：实时错误“91”     Object 变量或 with 块变量没有设置
可能是没有下载完所致，

Private Sub WebBrowser1_DownloadComplete()
if webbrowser.busy=false then
Dim doc, objhtml
Set doc = WebBrowser1.Document

Set objhtml = doc.body.createtextrange()
If Not IsNull(objhtml) Then
Text1.Text = objhtml.htmltext
End If
end if
End Sub

你要得网页源码用 xmlhttp比较好

先引用 msxml

Dim x As New MSXML2.XMLHTTP
x.open "get", "http://www.sina.com", False
x.send

MsgBox StrConv(x.responseBody, vbUnicode)

我在网上找到使用rft控件保存webbrowse文本   txtHtml是RichTextBox
txtHTML.Text = WebBrowser1.document.body.innerText
'flag ：rsftext 保存为txt文件，strtmp文件路径

=====================================================================================

Private Sub WebBrowser1_DownloadComplete()
     Dim objHtml As Object
     '下载完成时状态栏显示“Link Finished”
     Set objHtml = Me.WebBrowser1.Document.Body.Createtextrange()
     If Not IsNull(objHtml) Then
         Text1.Text = objHtml.htmltext
     End If
End Sub
使用inet控件
Source1 = Inet1.OpenURL("www.csdn.net")
If Source1 <> "" Then
RichTextBox1.Text = Source1
Me.Inet1.Cancel
Else
Source = MsgBox("Source code is not available.", vbInformation, "Source Code")
End If

Private Sub Command1_Click()
     Text1.Text = WebBrowser1.Document.body.innerHTML
End Sub

==================================================================================
加入timer,commandbutton,text
private sub command1_click()
webbrowser1.navigate http://www.sohu.com/
timer1.enabled=true
end sub

private sub timer1_timer()
dim doc,objhtml as object
dim i as integer
dim strhtml as string

if not webbrowser1.busy then
set doc=webbrowser1.document
i=0
set objhtml=doc.body.createtextrange()
if not isnull(objhtml) then
text1.text=objhtml.htmltext
end if
timer1.enabled=false
end if
end sub

Dim doc, objhtml As Object
If Not webbrowser1.Busy Then
          Set doc = webbrowser1.Document
          Set objhtml = doc.body.createtextrange()
          If Not IsNull(objhtml) Then
             text1.text=objhtml.htmltext
          End If
          Set doc = Nothing
          Set objhtml = Nothing

End If

或者试试用InternetReadFile，效果也可以：
Option Explicit

Private Declare Function InternetOpen Lib "wininet.dll" Alias "InternetOpenA" ( _
                     ByVal sAgent As String, ByVal lAccessType As Long, _
                     ByVal sProxyName As String, ByVal sProxyBypass As String, _
                     ByVal lFlags As Long) As Long
Private Declare Function InternetOpenUrl Lib "wininet.dll" Alias "InternetOpenUrlA" ( _
                     ByVal hInternetSession As Long, ByVal sUrl As String, _
                     ByVal sHeaders As String, ByVal lHeadersLength As Long, _
                     ByVal lFlags As Long, ByVal lContext As Long) As Long
Private Declare Function InternetReadFile Lib "wininet.dll" ( _
                     ByVal hFile As Long, ByVal sBuffer As String, _
                     ByVal lNumBytesToRead As Long, _
                     lNumberOfBytesRead As Long) As Integer
Private Declare Function InternetCloseHandle Lib "wininet.dll" ( _
                     ByVal hInet As Long) As Integer
Private Const INTERNET_FLAG_NO_CACHE_WRITE = &H4000000
Dim s

Private Function GetUrlFile(stUrl As String) As String
     Dim lgInternet As Long, lgSession As Long
     Dim stBuf As String * 1024
     Dim inRes As Integer
     Dim lgRet As Long
     Dim stTotal As String
     stTotal = vbNullString
     lgSession = InternetOpen("VBTagEdit", 1, vbNullString, vbNullString, 0)
     If lgSession Then
         lgInternet = InternetOpenUrl(lgSession, stUrl, vbNullString, _
                                      0, INTERNET_FLAG_NO_CACHE_WRITE, 0)
         If lgInternet Then
             Do
                 inRes = InternetReadFile(lgInternet, stBuf, 1024, lgRet)
                 stTotal = stTotal & Mid$(stBuf, 1, lgRet)
             Loop While (lgRet <> 0)
         End If
         inRes = InternetCloseHandle(lgInternet)
     End If
     GetUrlFile = stTotal
End Function

Private Sub Command1_Click()
     Text1.Text = GetUrlFile("http://adsl.tsee.net/teleplay/view.asp?id=143")
End Sub

====================================================================================================

Set vDoc = WebBrowser1.Document
'获取网页的源码
For Each o In vDoc.All
    DoEvents
    htmlpage = htmlpage & o.innerHTML
Next
然后用写二进制文件的方法将htmlpage的内容写入到.html文件中如果这个网页中含有框架那么要对框加进行处理。
