获取webbrowser控件 网页的源码（收藏）

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 ""
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 ""
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", "", 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
txtHTML.saveFile strtmp, rtfText

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

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("")
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
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 lAclearcase/" target="_blank" >ccessType 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("")
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。
