VBA - 从 Internet Explorer 的框架通知栏中选择另存为

Question

我正在尝试通过 Internet Explorer 的 框架通知栏 下载保存为的文件。 但是经过大量搜索后，我只找到了在框架通知栏上单击save 的解决方案。 到目前为止，我一直在尝试在示例网站上另存为文件：

使用以下代码：

' Add referenses
' Microsoft Internet Controls
' Microsoft HTML Object Library
' UIAutomationClient (copy file from C:\Windows\System32\UIAutomationCore.dll to Documents Folder)

#If VBA7 Then
    Private Declare PtrSafe Function FindWindowEx _
        Lib "user32" _
        Alias "FindWindowExA" ( _
        ByVal hWnd1 As LongPtr, _
        ByVal hWnd2 As LongPtr, _
        ByVal lpsz1 As String, _
        ByVal lpsz2 As String) _
        As LongPtr
#Else
    Private Declare Function FindWindowEx _
        Lib "user32" _
        Alias "FindWindowExA" ( _
        ByVal hWnd1 As Long, _
        ByVal hWnd2 As Long, _
        ByVal lpsz1 As String, _
        ByVal lpsz2 As String) _
        As Long
 #End If

    Dim subpage As InternetExplorer
    Dim objpage As HTMLDocument
    Dim o As CUIAutomation
    Dim h As LongPtr
    Dim fnb As LongPtr
    Dim e As IUIAutomationElement
    Dim iCnd As IUIAutomationCondition
    Dim Button As IUIAutomationElement
    Dim InvokePattern As IUIAutomationInvokePattern
    Dim strBuff As String
    Dim ButCap As String

    Set objshell = CreateObject("Shell.Application")
    Set objallwindows = objshell.Windows
    Set subpage = New InternetExplorer
    For Each ow In objallwindows
        'MsgBox ow
        If (InStr(1, ow, "Internet Explorer", vbTextCompare)) Then
            'MsgBox ow.Hwnd & "  " & ow & "   " & ow.locationURL
            If (InStr(1, ow.locationURL, "tvsub", vbTextCompare)) Then
                Set subpage = ow
            End If
        End If
    Next
    Set objpage = New HTMLDocument
    If subpage Is Nothing Then
    Else
        Set objpage = subpage.Document
        'Debug.Print objpage
        'objpage.getElementById("content").Click
        Set dl = objpage.getElementsbyclassname("subtable")
        Set dltable = dl(0).FirstChild.ChildNodes
        Set dlrow = dltable(10).getElementsByTagName("a")(2)
        dlrow.Click
        While objpage.ReadyState <> "complete"
            DoEvents
        Wend
    End If
    Application.Wait (Now() + TimeValue("0:00:05"))
    Set o = New CUIAutomation
    h = subpage.Hwnd
    fnb = FindWindowEx(h, 0, "Frame Notification Bar", vbNullString)
    If fnb = 0 Then Exit Sub
    'Debug.Print "type of fnb is " & TypeName(fnb)
    Set e = o.ElementFromHandle(ByVal fnb)
    'Debug.Print "type of e is " & TypeName(e)
    Set iCnd = o.CreatePropertyCondition(UIA_NamePropertyId, "Save")
    Set Button = e.FindFirst(TreeScope_Subtree, iCnd)
    'Debug.Print "type of Button is " & TypeName(Button)
    Set InvokePattern = Button.GetCurrentPattern(UIA_InvokePatternId)
    'Debug.Print "type of InvokePattern is " & TypeName(InvokePattern)
    InvokePattern.Invoke

End Sub

我尝试将"Save" 更改为"Save as"，但它不起作用。我的猜测是，在访问另存为按钮之前，我需要先以某种方式单击拆分按钮上的箭头，但我没有成功。 如果有人可以提供解决方案，将不胜感激。

我尝试通过链接http://www.tvsubtitles.net/download-114117.html 下载一个文件，该链接可以在网页http://www.tvsubtitles.net/subtitle-114117.html 上找到，它对我有用，这里是代码：

Sub Test_download_tvsubtitles_net()

    DownloadFile "http://www.tvsubtitles.net/download-114117.html", ThisWorkbook.Path & "\download-114117.zip"

End Sub

Sub DownloadFile(sUrl, sPath)

    Dim aBody

    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", sUrl, False
        .Send
        aBody = .responseBody
    End With
    With CreateObject("ADODB.Stream")
        .Type = 1 ' adTypeBinary
        .Open
        .Write aBody
        .SaveToFile sPath, 2 ' adSaveCreateOverWrite
        .Close
    End With

End Sub
