如何按下鼠标键就可获取鼠标当前位置的网页元素的ID或者Title等属性？
请问如何做这样一个工具：
鼠标在当前网页的某个文档元素上按下中键（或者右键也可），可以将鼠标位置所在的网页元素的ID或者Title输出到一个window窗口的文本框里？
提供一下思路也可。

引用Microsoft HTML Object Library
Private WithEvents m_oDoc As HTMLDocument
Private Sub Form_Load()
WebBrowser1.Navigate2 "www.google.cn "
End Sub
Private Sub m_oDoc_onmouseup()
Dim oEvent As CEventObj
Set oEvent = m_oDoc.parentWindow.event
Dim oElement As IHTMLElement
With oEvent
If .Button = vbRightButton Then
Set oElement = .srcElement
With oElement
Debug.Print .tagName, .Id, .Title, .innerHTML
End With
End If
End With
End Sub
Private Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
Set m_oDoc = pDisp.Document
End Sub

我这里收藏了个好东东:
可以对其它进程的IE窗口内容进行查看.
原本我是用它来取网页星号的,现在用它来也可以实现你的要求.
保存到一个模块里,引用 " ".
然后调用GetPassword就可以了:
tmpI = GetPassword(hwnd,mx,my)
