Webbrowser控件

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 Sub

Private 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 = "IMGod@paradise.com"                End Select            ElseIf vTag.Type = "submit" Then                vTag.Click            End If        End If    Next iEnd Sub'点击Command1就可以自动填表并提交了

另个代码:'要引用一个Microsoft XML 的组件

Option ExplicitDim xml As New XMLHTTPPrivate Sub Command1_Click()   Call AccessNetEnd Sub

Private Sub AccessNet()    On Error Resume Next    Dim str1 As String    xml.Open "POST", "http://yourWeb/handle.asp", False        xml.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"        xml.send "UserName=" & Text1.Text & "&Password=" & Text2.Text        If xml.Status = 200 Then       str1 = StrConv(xml.responseBody, vbUnicode) '返回的内容       MsgBox str1    End IfEnd Sub

'或者改为:

Option ExplicitDim xml As ObjectPrivate Sub Command1_Click()   Call AccessNetEnd Sub

Private Sub AccessNet()    On Error Resume Next    Dim str1 As String    Set xml = CreateObject("MSXML2.XMLHTTP")    xml.Open "POST", "http://yourWeb/handle.asp", False        xml.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"        xml.send "UserName=" & Text1.Text & "&Password=" & Text2.Text        If xml.Status = 200 Then       str1 = StrConv(xml.responseBody, vbUnicode) '返回的内容       MsgBox str1    End IfEnd Sub
