We have a new asp.net application.

I need to call - one of the methods -  inside one of the aspx pages  - in the above asp.net application -  from an existing classic asp page.

I found couple of ways to acomplish this. But I noticed all those approaches  involve a high degree of complexity for example approches using com or com+. I am wondering if there is any other simpler way by which I can accomplish the same.

I am not sure if I can accomplish this by means of a sql stored procedure and accessing it directy from the classic asp page itself. If so, I no longer need the call to asp.net page.

Thanks,

RP

Additional information: The asp.net application is for retrieving a file from a sql Filestream. If I can accomlish the same functionality from classic asp page itself directly - then the problem is solved. But I am not sure if that works.

I would suggest you to create separate library (.DLL)   and then you can access that code in both ASP and ASP.NET Pages...

Or You can also create simple web service and access in both ASP and ASP.NET. this will be correct approach.

Let me know.

Thanks for your sugestion. I would like to choose the web service path.

I created a test web service with a test web method like below. I created the webservice as part of the asp.net application.

Public Class FileSteamGatewayFacade
    Inherits WebService
    <WebMethod(Description:="Simple method")> _
    Public Function GetName(ByVal sName As String) As String
        Return "The name is: " & sName
    End Function

In the classic asp page, I have the following code.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title></title>
</head>
<body>
<%

'Option Explicit
Response.Write "Test ASP Page"

Dim objRequest, objXMLDoc, objXmlNode
Dim strRet, strError, strName

strName = "Julian"

Set objRequest = Server.CreateObject("MSXML2.XMLHTTP")

With objRequest
.open "GET", "http://localhost/FileStreamDemo/test/FileSteamGatewayFacade.asmx/GetName?sName=" & _
strName, False
.setRequestHeader "Content-Type", "text/xml"
.setRequestHeader "SOAPAction", "http://localhost/FileStreamDemo/test/FileSteamGatewayFacade.asmx/GetName?sName=" & _
strName
.send
End With

Set objXMLDoc = Server.CreateObject("MSXML2.DOMDocument")
objXMLDoc.async = false

Response.Write(objRequest.statusText)

'If myXML.loadXML(SoapRequest.responseXML.Xml) Then
'Set objXMLNode = myXML.selectSingleNode("GetNameResponse")

'if Not objXMLNode Is Nothing then
'strRet = objXMLNode.NodeTypedValue
'Response.Write("Response:" &sRet)
'End If
'Else
'strError = myXML.parseError.reason
'Response.Write("Error" & strError)
'EndIf

 %>

</body>
</html>

The first line response.write it working. The call to the webservice is not working. It ends up with an internal error 500.

Please let me know your suggestions.

Thanks

I am able to resolve it by using an alternative approach using SOAP/WSDL.

Thanks
