如何使用 VBA 從 Internet Explorer 下載文件

Question

我正在嘗試從 Internet Explorer 11 下載 Excel 工作簿，當我單擊該鏈接時，會出現以下彈出消息：

我試過使用 sendkeys "%s" 但它沒有用。 如果不使用 IE，我無法使用代碼從 Internet 下載文件，因為 URL 是我公司的內部網站。

Sub Site()
    Dim IE As Object
    Set IE = CreateObject("InternetExplorer.application")
    With IE
        .Visible = True
        .Navigate "http://asint010/IntegradorProfit/Pages/Relatorios/FluxoSolicitacao.aspx"

        While .Busy Or .ReadyState <> 4
            DoEvents
        Wend

        .document.All("ctl00_ContentPlaceHolder1_btnexportar").Click
        While .Busy Or .ReadyState <> 4
            DoEvents
        Wend

       'here I don't know what to do

    End With
End Sub

我正在使用此代碼下載文件。 您需要根據您的語言設置更改代碼。 您也可以刪除一些不需要的聲明功能行。

Declare PtrSafe Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
    Declare PtrSafe Function SetWindowText Lib "user32" Alias "SetWindowTextA" (ByVal hWnd As Long, ByVal lpString As String) As Long
    Declare PtrSafe Function SetForegroundWindow Lib "user32" (ByVal hWnd As Long) As Long

    Declare PtrSafe Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
    Declare PtrSafe Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long

           'here I don't know what to do
            hpass = IE.hWnd
            DownloadFile (hpass)

        End With

    Sub DownloadFile(h As Long)

        Set o = New CUIAutomation
        h = FindWindowEx(h, 0, "Frame Notification Bar", vbNullString)
        If h = 0 Then Exit Sub

        Set e = o.ElementFromHandle(ByVal h)
        Set iCnd = o.CreatePropertyCondition(UIA_NamePropertyId, "Save")
        Set Button = e.FindFirst(TreeScope_Subtree, iCnd)
