无法设置 Internet Explorer 11 以获得焦点

Question

我在 IE11 中使用 MS ACCESS 宏保存下载的文件时遇到问题。

这是我在下载链接后想要点击的地方：

我需要使用用户名/密码登录才能进入该页面。

我目前正在使用 SendKeys 来获取文件，当我手动执行我的宏时，它可以完美运行。但是，当我使用 Windows 计划任务启动宏时，Internet Explorer 失去焦点，发送键在桌面上执行。

我尝试了几件事，包括：

-IE.Visible = true

-使用 Shell 对象执行 sendkeys

-尝试了自动化，但我无法使其工作（我不再使用该方法使用“sendkeys”）。我看到有几个关于堆栈溢出的主题可以帮助我，但我没有成功让它们工作：Controlling IE11 "Do you want to Open/Save" dialogue window buttons in VBA 或IE11 Frame Notification Bar Save button

-尝试通过链接下载，但无法正常工作

这是我的代码，我隐藏了重要字段。请原谅评论中的法国人

您可以尝试参考下面的步骤和示例代码，并尝试修改您的代码可能有助于解决问题。

复制文件 C:\Windows\System32\UIAutomationCore.dll 文件到用户文档，即 C:\Users\admin\Documents 然后添加参考 UIAutomationClient 到您的宏文件中。

将以下代码粘贴到您的模块中：

    Option Explicit
    Dim ie As InternetExplorer
    Dim h As LongPtr
    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

Sub Download()
    Dim o As IUIAutomation
    Dim e As IUIAutomationElement
    Set o = New CUIAutomation
    h = ie.Hwnd
    h = FindWindowEx(h, 0, "Frame Notification Bar", vbNullString)
    If h = 0 Then Exit Sub

    Set e = o.ElementFromHandle(ByVal h)
    Dim iCnd As IUIAutomationCondition
    Set iCnd = o.CreatePropertyCondition(UIA_NamePropertyId, "Save")

    Dim Button As IUIAutomationElement
    Set Button = e.FindFirst(TreeScope_Subtree, iCnd)
    Dim InvokePattern As IUIAutomationInvokePattern
    Set InvokePattern = Button.GetCurrentPattern(UIA_InvokePatternId)
    InvokePattern.Invoke
End Sub
