使用 VBA 通过窗口标题获取 IE 窗口对象

Question

我找到了@mkingston 提供的这个解决方案： How to intercept and manipulate a Internet Explorer popup with VBA

...但这对我不起作用。我已经添加了两个有问题的参考库，但是当我运行脚本时，我遇到了这些问题：

编译错误：由于 pauseUntilIEReady 导致的未定义 Sub（由于此 Sub 未包含在答案中，因此我将其从脚本中删除）

编译错误：参数不是可选的，因为 oGetIEWindowFromTitle （所以我尝试解决这个问题以编译脚本）

脚本最终编译后，报错：

自动化错误 系统找不到指定的文件。

在这行代码上： 对于 objShellWindows 中的每个 oGetIEWindowFromTitle

这是我要运行的代码：

Function oGetIEWindowFromTitle(sTitle As String, _
                           Optional bCaseSensitive As Boolean = False, _
                           Optional bExact As Boolean = False) As SHDocVw.InternetExplorer

Dim objShellWindows As New SHDocVw.ShellWindows
Dim found As Boolean
Dim startTime As Single

found = False
'Loop through shell windows
For Each oGetIEWindowFromTitle In objShellWindows
    found = oGetIEWindowFromTitleHandler(oGetIEWindowFromTitle, sTitle, bCaseSensitive, bExact)
    If found Then Exit For
Next

'Check whether a window was found
If Not found Then
    Set oGetIEWindowFromTitle = Nothing
Else
    'COMMENTED OUT TO GET SCRIPT TO COMPILE pauseUntilIEReady oGetIEWindowFromTitle
End If

End Function


Private Function oGetIEWindowFromTitleHandler(win As SHDocVw.InternetExplorer, _
                                  sTitle As String, _
                                  bCaseSensitive As Boolean, _
                                  bExact As Boolean) As Boolean

oGetIEWindowFromTitleHandler = False

On Error GoTo handler
'If the document is of type HTMLDocument, it is an IE window
If TypeName(win.Document) = "HTMLDocument" Then
    'Check whether the title contains the passed title
    If bExact Then
        If (win.Document.title = sTitle) Or ((Not bCaseSensitive) And (LCase(sTitle) = LCase(win.Document.title))) Then oGetIEWindowFromTitleHandler = True
    Else
        If InStr(1, win.Document.title, sTitle) Or ((Not bCaseSensitive) And (InStr(1, LCase(win.Document.title), LCase(sTitle), vbTextCompare) <> 0)) Then oGetIEWindowFromTitleHandler = True
    End If
End If
handler:
'We assume here that if an error is raised it's because
'the window is not of the correct type. Therefore we
'simply ignore it and carry on.

End Function

和

Sub test()

Dim ie As SHDocVw.InternetExplorer
Dim doc As HTMLDocument 'If you have a reference to the HTML Object Library
'Dim doc as Object 'If you do not have a reference to the HTML Object Library

' Change the title here as required
Set ie = oGetIEWindowFromTitle("My popup window")
Set doc = ie.Document

Debug.Print doc.getElementsByTagName("body").Item(0).innerText

End Sub

这对我有用。

Function IEWindowFromTitle(sTitle As String) As SHDocVw.InternetExplorer

    Dim objShellWindows As New SHDocVw.ShellWindows
    Dim win As Object, rv As SHDocVw.InternetExplorer

    For Each win In objShellWindows
        If TypeName(win.Document) = "HTMLDocument" Then
            If UCase(win.Document.Title) = UCase(sTitle) Then
                Set rv = win
                Exit For
            End If
        End If
    Next

    Set IEWindowFromTitle = rv

End Function

Sub Tester()

    Dim w As SHDocVw.InternetExplorer
    Set w = IEWindowFromTitle("Google")
    If Not w Is Nothing Then
        Debug.Print w.Document.Title
    Else
        Debug.Print "Not found"
    End If

End Sub
