Default XMLHTTP

With ASP

//Client (To ASP and ASP .Net)
var oXMLHTTP = new ActiveXObject("Microsoft.XMLHTTP");
oXMLHTTP.open('POST', sHRef, false)
oXMLHTTP.send(sXML);

//Server
Set oXML = Server.CreateObject("MSXML.DOMDocument")
oXML.load(Request)

Using ASP that's all right, but in ASP .Net I can't request data in server side.
If anybody can help...please...


Tanks!

In ASP.NET, expose data through Web Service, which return an XML document:

<WebMethod()>
Public Function HelloWorld() As String
    HelloWorld = "Hello World"
End Function

this return an XML like:
<string>Hello World</string>

then you can use the same client code to get the data
Hope this help.

There is 2 types of client codes:

1) client code run from browser (same as your client-side code in 1st message):

//-------------------------------------
// Client.asp
//-------------------------------------

//request XML object is optional if you want to send data to Server
var oXMLReq = new ActiveXObject("Msxml2.DOMDocument.4.0");
oXMLReq.loadXML("<?xml vedrsion='1.0'?><Root>My request</Root>");

//transport XMLHTTP object
var oXMLHTTP = new ActiveXObject("Msxml2.XMLHTTP.4.0");
oXMLHTTP.open("post", sHRef, false);
oXMLHTTP.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
oXMLHTTP.send(oXMLReq); //or oXMLHTTP.send() if no data to send

//response XML object
var oXMLRes = new ActiveXObject("Msxml2.DOMDocument.4.0");
oXMLRes.loadXML(oXMLHTTP.responseText);
alert(oXMLRes.documentElement.text);

2) Client code run on Server (use ServerXMLHTTP instead of XMLHTTP)

<%@ Language=VBScript %>
<%
Dim oXMLReq
Dim oXMLHTTP
Dim oXMLRes

Set oXMLReq = Server.CreateObject("Msxml2.DOMDocument.4.0")
Call oXMLReq.loadXML("<?xml version='1.0'?><Root>My request</Root>")

Set oXMLHTTP = Server.CreateObject("Msxml2.ServerXMLHTTP.4.0")
Call oXMLHTTP.open("post", sHRef, false)
Call oXMLHTTP.setRequestHeader("Content-Type", "application/x-www-form-urlencoded")
Call oXMLHTTP.send(oXMLReq)

Set oXMLRes = Server.CreateObject("Msxml2.DOMDocument.4.0")
Call oXMLRes.loadXML(oXMLHTTP.responseText)
Call Response.Write(oXMLRes.documentElement.text)
%>

Here is Server codes:

//-------------------------------------
// Server_on_ASP.asp
//-------------------------------------
<%@ Language=VBScript %>
<%
Dim oXMLReq
Set oXMLReq = Server.CreateObject("Msxml2.DOMDocument.4.0")
Call oXMLReq.load(Request)
.......... do something with client XML object........

'send a response XML string (not XML object)
Call Response.Write("<MyResponse>OK</MyResponse>")
%>

To request data from ASP.NET Web Service, you must change your client code a little bit

//-------------------------------------
// Client_for_NET.asp
//-------------------------------------

//request data from Web Service "Server_on_NET", method "GetRequest"
var sHRef = "http://server/Server_on_NET.asmx/GetRequest";

//send 2 parameters "ProductID" and "Customer"
var sParams = "ProductID=5&Customer=KhoaNguyen";

var oXMLHTTP = new ActiveXObject("Msxml2.XMLHTTP.4.0");
oXMLHTTP.open("POST", sHRef, false);
oXMLHTTP.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
oXMLHTTP.send(sParams);

........ same as above............

//-------------------------------------
// Server_on_NET.asmx (Web Service)
//-------------------------------------
<WebMethod()>
Public Function GetRequest(ByVal ProductID As Integer, ByVal Customer As String) As String
   'do something with ProductID and Customer

   Return "OK"
End Function


You should see "OK" on your client side
Hope this help.

Hi guys,
I need some help with XML HTTP object. I am using the following code to retrieve the HTML in a string of a specified URl. For some reason it doesn't work for the website i need. https://www.dallascounty.org/servlet/padb1#
At first i thought that this doesn't work with Https url's but i have tried with many and it did. When i use the above URl it gives me a 500 Servlet exception.
I am using this in ASP.
<%
  Response.Buffer = True
  Dim objXMLHTTP, xml

  ' Create an xmlhttp object:
  Set xml = Server.CreateObject("Microsoft.XMLHTTP")
  ' Or, for version 3.0 of XMLHTTP, use:
  ' Set xml = Server.CreateObject("MSXML2.ServerXMLHTTP")

  ' Opens the connection to the remote server.
  xml.Open "GET", "http://www.4Guysfromrolla.com/", False

  ' Actually Sends the request and returns the data:
  xml.Send

  'Display the HTML both as HTML and as text
  Response.Write "<h1>The HTML text</h1><xmp>"
  Response.Write xml.responseText
  Response.Write "</xmp><p><p><h1>The HTML Output</h1>"

  Response.Write xml.responseText


  Set xml = Nothing
%>

I'll appreciate your response and if it cannot be done pls if u have any information about retrieving the String of URLS like the one i mentioned? do let me know.
Bye
