如何在不导入新文件的情况下异步发出请求

Question

我正在尝试执行 SOAP 调用，但有时响应是数千条记录。我不希望 Excel 在处理响应时冻结，但我看到的每个示例都需要使用异步回调导入单独的文件。有没有办法可以在没有额外文件的情况下做到这一点？

Public Function SendPost(currentTableAltIden As String, altIdentifiers() As String, Optional aSync As Boolean = True)
Dim t As XMLHTTP60
Dim r As MSXML2.DOMDocument60
Dim nodeList As IXMLDOMNodeList
Dim i As Integer
Dim listLengthControl As Integer
Dim listCounter As Integer
Dim xmlHelper As AsyncHelper

  i = 0
   Set t = Transport
   Set xmlHelper = New AsyncHelper
       xmlHelper.init t
   t.Open "POST", EndPointUrl, aSync
   
   
   t.send Text
   
   Set r = New MSXML2.DOMDocument60
   r.aSync = False
   r.validateOnParse = False
   r.SetProperty "SelectionNamespaces", " xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'"
   r.LoadXML t.responseText
   
   Set nodeList = r.SelectNodes("//result//" & currentTableAltIden)
   listLengthControl = nodeList.Length
   
   While listCounter <> listLengthControl
      For i = LBound(altIdentifiers) To UBound(altIdentifiers)
                  Debug.Print r.SelectNodes("//result//" & currentTableAltIden & "//" & altIdentifiers(i))(listCounter).Text
                  WorkWebServiceTemp.Cells(TableDataRowNum + listCounter, i + 1).value = r.SelectNodes("//result//" & currentTableAltIden & "//" & altIdentifiers(i))(listCounter).Text
      Next i
      listCounter = listCounter + 1
   Wend

      
End Function

Sub AsyncTester()

    Static col As Collection

    Set col = New Collection
    col.Add AsyncFetcher("https://whosebug.com/", New clsTest)
    col.Add AsyncFetcher("https://google.com/", New clsTest)
    col.Add AsyncFetcher("https://news.ycombinator.com/", New clsTest)

    Debug.Print "finished setup"

End Sub


Function AsyncFetcher(url As String, callBackObject As Object)
    Dim sc As Object
    Set sc = CreateObject("MSScriptControl.ScriptControl")
    sc.Language = "JScript"
    sc.AddCode "var objXML, theUrl, objCallBack;"
    sc.AddCode " function callBack(){objCallBack.Report(objXML.readystate + ' ' + theUrl);}  " & vbLf
    sc.AddCode " function fetch(url, obj){                                    " & vbLf & _
               "   objCallBack = obj; theUrl = url;                           " & vbLf & _
               "   objXML = new ActiveXObject('Msxml2.XMLHttp.6.0');          " & vbLf & _
               "   objXML.onreadystatechange = callBack;                      " & _
               "   objXML.open(""GET"", url, true);                           " & vbLf & _
               "   objXML.send();                                             " & vbLf & _

    sc.Run "fetch", url, callBackObject

    Set AsyncFetcher = sc

End Function

clsTest:

Public Sub Report(s)
    Debug.Print s
