vb中用webbrowser编程模拟浏览器自动访问某个网页中的链接

将种子URL的Source得到再通过<A HREF= 与Space之间分离贝。

用WebBrowser的Document属性访问HTML文档，用document.all.tags("a").item(index)访问第Index-1个链接，当然index也可以是链接的ID

控制网页的FORMS行为Private Sub Command2_Click()
    With WebBrowser1.Document.Forms(0)
        .c2.Checked = 1
        .r1(1).Checked = 1
    End With
End Sub
Private Sub Command2_Click()
    With WebBrowser1.Document.Forms(0)
        .d1.Options(1).Selected = 1
    End With
End Subweb.Document.getElementsByName("D1").Item(0).selectedIndex = 1＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
<input type="radio" value="n" checked name="notecome">普通
<input type="radio" value="c" name="notecome">原创
<input type="radio" value="z" name="notecome">转帖
<input type="button" value="发送提交" name="button"比如一个网页里有如上代码
我想选择原创
webbrowser中怎么写
Private Sub Command1_Click()
    WebBrowser1.Navigate "c:\ggg.html"
End SubPrivate Sub Command2_Click()
    Dim x

    For Each x In WebBrowser1.Document.All("notecome")
        If x.Value = "c" Then
            x.Checked = True
        End If
    Next
End Sub============================================================================================
假设你的HTML代码如下：<html>
<script>
  function abcd(){
    alert("haha");
    return false;
  }
</script><body>
  <a id = 'xxx' href=# onclick="abcd()">ggggg</a>
</body>
</html>VB代码如下：
Private Sub Command1_Click()
    WebBrowser1.Navigate "http://www.applevb.com/script_test.html"
End SubPrivate Sub Command2_Click()
    Dim a, b
    Dim d As IHTMLDocument2

    For Each a In WebBrowser1.Document.All
        Debug.Print a.tagName
        If (a.tagName = "SCRIPT") Then        End If
        If (a.tagName = "A") Then
            If a.Id = "xxx" Then
                a.FireEvent ("onclick")
            End If
        End If
    Next点击Command1浏览这个网页，点击Command2运行其中的脚本abcd。
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝怎么编程把用户名，密码提交到网页上的登录页？
首先在程序中加入Webbrowser控件并加入引用 Microsoft HTML Object Library。
假设你的HTML页面表单代码如下：
<form method="POST" action="http://chen/dll/chat/chatmain.exe/RegUser">
  <p>请填写下面表单注册（*项为必添项）</p>
  <p>*姓名<input type="text" name="Name" size="20"></p>
  <p>*昵称<input type="text" name="NickName" size="20"></p>
  <p>电子邮件<input type="text" name="EMail" size="20"></p>
  <p>*密码<input type="text" name="Password" size="20"></p>
  <p><input type="submit" value="提交" name="B1"><input type="reset" value="全部重写" name="B2"></p>
</form>
注意其中元素的type、Name、value属性。然后VB中的代码如下：
Private Sub Command1_Click()
    WebBrowser1.Navigate "http://chen/chat/newuser.htm"
End SubPrivate Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
    Dim vDoc, vTag
    Dim i As Integer

    Set vDoc = WebBrowser1.Document
    List1.Clear
    For i = 0 To vDoc.All.length - 1
        If UCase(vDoc.All(i).tagName) = "INPUT" Then
            Set vTag = vDoc.All(i)
            If vTag.Type = "text" Or vTag.Type = "password" Then
                List1.AddItem vTag.Name
                Select Case vTag.Name
                    Case "Name"
                        vTag.Value = "IMGod"
                    Case "NickName"
                        vTag.Value = "IMGod"
                    Case "Password"
                        vTag.Value = "IMGodpass"
                    Case "EMail"
                        vTag.Value = "[email protected]"
                End Select
            ElseIf vTag.Type = "submit" Then
                vTag.Click
            End If
        End If
    Next i
End Sub
点击Command1就可以自动填表并提交了。

调用forms下的Submit控件的Click事件,我会做,但我不想这么做.有没有办法直接调用类似于:web1.document.forms.submit,这句语句我怎么写都不成功
是这个
Webbrowser1.document.formName.submit()不能用,formname为form1所以我调用Webbrowser1.document.form1.submit
出错类型:对象不支持该属性或方法,
然后调用Webbrowser1.document.forms(0).submit()
出错类型同上
Private Sub Command1_Click()
    WebBrowser1.Navigate "http://localhost/webapplication2/MyLogonPage.aspx"
End SubPrivate Sub Command2_Click()
    WebBrowser1.Document.All("Form1").submit
End Sub
<form name="form1" method="post" action="aa.asp">
......
<input name="reset" type="reset" vlaue="reset" class="button">
</form>
我本想把reset的type改成submit 再提交,可出错,type是只读属性,不能修改,我只要有办法把这页面递交出去就行,当然,用POST也不行,参数太多,组合方式太多
你用下面的代码试一下你的页面：
Private Sub Command1_Click()
    WebBrowser1.Navigate "http://oakhome.xicp.net/webapplication2/MyLogonPage.aspx"
End SubPrivate Sub Command2_Click()
    Dim x

    On Error Resume Next
    For Each x In WebBrowser1.Document.All
        List1.AddItem x.Name
    Next
End Sub看看在List1里面列出来的页面元素的名字有没有Form1
找到原因了,你的页面是这样的:
<input language="javascript" onclick="if (typeof(Page_ClientValidate) == 'function') Page_ClientValidate(); " name="Submit1" id="Submit1" type="submit" value="Submit" />
你把name="Submit1" 改成name="Submit"肯定就不会成功了,很不幸的是我要提交的页面中就有这样一句,现在可有办法解决吗???=======================================================================

一个把页面保存为MHT(即MHTML)文件
1、谢谢楼上几位大侠！我现在将 pcwak(书剑狂生[MS MVP]) 大侠提供的资料贴出来，以供大家参考：
我终于找到一个把页面保存为MHT(即MHTML)文件的方法了!
首先，在工程中必须要引用一个库：
Library CDO
D:\WINNT\System32\cdosys.dll
Microsoft CDO for Windows 2000 Library
其次，需要Stream对应的接口的支持，如果你一时找不到就使用支持这个的较新的ADO就行了，如
Library ADODB
D:\Program Files\Common Files\system\ado\msado15.dll
Microsoft ActiveX Data Objects 2.5 Library
代码如下，十分简单(同时由于流的特点，显示在实际应用中没必要象本例中那样把文件保存到磁盘上就可直接转换为字符串或字节数组什么的处理的。另，对于Microsoft CDO for Windows 2000 Library这个库，在WIN98中要怎么使用还没试过，感兴趣的朋友可以试试并跟帖，以丰富完善其内容：)Private Sub Command1_Click()
' Reference to Microsoft ActiveX Data Objects 2.5 Library
' Reference to Microsoft CDO for Windows 2000 Library
Dim iMsg As New CDO.Message
Dim iConf As New CDO.Configuration
Dim objStream As ADODB.StreamWith iMsg
.CreateMHTMLBody "http://www.163.com/";, , _
"domain\username", _
"password"
Set objStream = .GetStream
Call objStream.SaveToFile("f:\test.mht", adSaveCreateOverWrite)
End With
End Sub2、
'首先加入对ADODB和CDO（Microsoft CDO for Windows 2000 Library，对应文件名为CDOSYS.dll）的引用
Private Sub Command1_Click()
    Dim message As New CDO.message
    Dim Outstream As ADODB.Stream
    On Error GoTo myerr1
    Call message.CreateMHTMLBody("http://www.csdn.net", CDO.CdoMHTMLFlags.cdoSuppressNone, "", "")
    Set Outstream = message.GetStream
    Call Outstream.SaveToFile("c:\test.mht", ADODB.SaveOptionsEnum.adSaveCreateOverWrite)
    MsgBox "完成"

    Exit Sub
myerr1:
    Set message = Nothing
    Set Outstream = Nothing
