打开网站时出现自动化错误

Question

嘿，我的VBA代码收到“自动化错误”：

Set Doc = IE.document

当我调试时，我得到以上作为罪魁祸首，当我将鼠标悬停在Doc上为空时，并且IE.document引发自动化错误

Application.ScreenUpdating = False
    Application.DisplayAlerts = False

    Dim IE As New InternetExplorer
    IE.Visible = True

    Dim Doc As HTMLDocument
    Set Doc = IE.document


    Dim Np As String

    For line = 2 To lp

        ipp = Worksheets("sheet1").Cells(line, 1).Value

        If ipp <> "" Then

            IE.navigate ipp

            Do
                DoEvents
            Loop Until IE.readyState = READYSTATE_COMPLETE

            Np = Doc.getElementsByName("TITLE")(0).innerText


        End If
        IE.Quit
    Next line


End Sub

[无论何时加载新页面，都需要刷新对新加载的文档的引用：

Set Doc = IE.document

... [在Do循环之后]
