webbrowser怎样清除默认浏览器的cookies

http://www.csdn.net/Develop/Read_Article.asp?Id=7694
参考The following code can be used to query and delete files in the internet cache (including cookies). A demonstration routine can be found at the bottom of this post. Note, the enumerated type eCacheType is not supported in Excel 97, but can be changed to a list of Public Constants eg. Public Const eNormal = &H1&.

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???=======================================================================
使用WebBrowser_V1接受消息Private WithEvents WebMessage As WebBrowser_V1Private Sub Form_Load()
  Set WebMessage = WebBrowser1.Object
End SubPrivate Sub WebMessage_NewWindow(ByVal URL As String, ByVal Flags As Long, ByVal TargetFrameName As String, PostData As Variant, ByVal Headers As String, Processed As Boolean)'这里有Flags变量可以取得窗体应有的状态End Sub具体值需要你自己去试试看。对象浏览器里面没有=======================================================================================================通过下面的方法遍历页面中的IFrame：Sub EnumFrames(ByVal wb As WebBrowser)
Dim pContainer As olelib.IOleContainer
Dim pEnumerator As olelib.IEnumUnknown
Dim pUnk As olelib.IUnknown
Dim pBrowser As SHDocVw.IWebBrowser2   Set pContainer = wb.Object.Document

   ' Get an enumerator for the frames
   If pContainer.EnumObjects(OLECONTF_EMBEDDINGS, pEnumerator) = 0 Then

      Set pContainer = Nothing

      ' Enumerate and refresh all the frames
      Do While pEnumerator.Next(1, pUnk) = 0

         On Error Resume Next

         ' Clear errors
         Err.Clear

         ' Get the IWebBrowser2 interface
         Set pBrowser = pUnk

         If Err.Number = 0 Then
            Debug.Print "Frame: " & pBrowser.LocationURL
         End If

      Loop

      Set pEnumerator = Nothing

   End If

End Sub
