Internet Explorer对象Excel VBA的自动化错误未指定的错误

Question

我一直在使用一些代码，从字面上看，它突然间突然中断了我。这是我收到的错误消息：

Run-time error '-2147467259 (80004005)'
Automation error
Unspecified error

该行代码专门用于实例化InternetExporer对象，除非我没有做任何更改。它只是停止工作。可能是什么问题？

之前发生过这种情况，我通过显式调用该库（之前为HTMLBsaeObject的MSHTML）进行了更正，但在命名变量时只使用了一个Object

Public Sub ValueLineResearch()

    setUp
    Dim myFund As String

    loginN = Sheets("Logins").Range("B2").Text
    pwStr = Sheets("Logins").Range("B3").Text

    'Get the site
    iEx.Navigate "https://jump.valueline.com/login.aspx"
    iEx.Visible = True

    Call waitForIE

    'Need to login now don't we
    iEx.Document.forms("aspnetForm").Item("ctl00_ContentPlaceHolder_LoginControl_txtUserID").Value = loginN
    iEx.Document.forms("aspnetForm").Item("ctl00_ContentPlaceHolder_LoginControl_txtUserPw").Value = pwStr
    iEx.Document.forms("aspnetForm").Item("ctl00_ContentPlaceHolder_LoginControl_btnLogin").Click

    Call waitForIE
    Application.Wait DateAdd("s", 6, Now)

    iEx.Navigate "https://research.valueline.com/secure/research#sec=library"

    Call waitForIE

    For Each el1 In iEx.Document.getElementsByClassName("symbol-search textInput ui-autocomplete-input mod_search-symbols primary_symbol_search")
        el1.Value = fundToResearch
    Next

    Application.Wait DateAdd("s", 2, Now)

    iEx.Document.forms("quoteSearch").submit

    Call waitForIE
    Application.Wait DateAdd("s", 2, Now)

    iEx.Navigate "https://research.valueline.com/secure/research#list=recent&sec=company&sym=" & fundToResearch

    Call waitForIE

    'store the Doc
    Set ieDoc = iEx.Document

    'For linkItem = 0 To ieDoc.Links.Length - 1
    '    'Get the PDF
    '    If InStr(1, ieDoc.Links(linkItem).href, ".pdf", vbTextCompare) > 0 And InStr(1, ieDoc.Links(linkItem).href, "UserGuide", vbTextCompare) <= 0 Then
    '        ieDoc.Links(linkItem).Click
    '        iEx.Visible = True
    '        Exit For
    '    End If
    'Next linkItem

    Set iEx = Nothing    

End Sub

设置子是这样的：

set iEx = CreateObject("InternetExplorer.Application")
fundToResarch = LCase(InputBox("Please Enter a Fund"))

我遇到了一个类似的问题，即“自动化错误”在多次调用的函数中创建InternetExplorer实例。它可以很好地启动，但是在多次通话后会由于自动化错误而崩溃。我发现内存中有多个IE进程，这意味着设置objIE = Nothing不足以从内存中删除该进程。解决方案是在将objIE设置为Nothing之前调用'Quit'方法。

那是：

objIE.Quit

'Put in a brief pause

set objIE = Nothing
