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)

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

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。
