This code allows the user control of a spreadsheet whilst the sheet is calling a webservice which takes a long time to return data.#

  • Create a Module in Excel or VB
  • Add a reference in Excel to Microsoft XML Dom
Private d As Class1

Sub doit()

    Set d = New Class1
    d.Execute
  


End Sub
  • Create a Class called Class1 in Excel or VB

Private WithEvents objXML As DOMDocument

Public count As Long

objXML.async = True
Dim loaded As Boolean

    
    loaded = objXML.Load("http://WEBSERVER/tradeblotter/getcounterparties.aspx")

    done = False
    
    If objXML.parsed Then
        Call objXML_ondataavailable
    End If
End Sub

Private Sub objXML_ondataavailable()

If Not done Then
    MsgBox "Got Counterparties"
    done = True
    DoEvents
End If

    Dim retNode As IXMLDOMNode

       Sheet2.Cells(intRow, 2).Value = retNode.Attributes.getNamedItem("label").Text
    Next

        }
        
        Response.ContentType = "text/xml";
        Response.Write(xmlDoc.InnerXml.ToString());

    }

}
  • Call the Function in the Module and wait for the data to be returned. The async code only works if there is a delay in the response from the webpage.
