Passing object from one web App to another web App and back (webRequest maybe) can you help?


Guys not sure if the right place for this. I am STUCK!!!!

I need to pass data from one web application to another web Application and back

Before implementing in the real work that I am doing , i have build a quick demo

2 Web Application Projects (WebAppA and WebAppB)
01 Class Library
With 2 Classes
RequestClass (1 Property amountToPay=10)
ResultClass (1 Property bool IsSuccess)

WebAppA.MakePayment.aspx has method call Pay

ResultClass rslt=payMethod(requestclass)  // this should be a call to WebAppB

WebAppB should return a result back .How can I do it??????


I have found the following on the net.But I not sure how to adapt to my needs.

How do i pass the data?

How webAppB receives it and send the result back?

  FOUND ON THE NET  // Create a request for the URL.        
            WebRequest request = WebRequest.Create ("");
            // If required by the server, set the credentials.
            request.Credentials = CredentialCache.DefaultCredentials;
            // Get the response.
            HttpWebResponse response = (HttpWebResponse)request.GetResponse ();
            // Display the status.
            Console.WriteLine (response.StatusDescription);
            // Get the stream containing content returned by the server.
            Stream dataStream = response.GetResponseStream ();
            // Open the stream using a StreamReader for easy access.
            StreamReader reader = new StreamReader (dataStream);
            // Read the content.
            string responseFromServer = reader.ReadToEnd ();
            // Display the content.
            Console.WriteLine (responseFromServer);
            // Cleanup the streams and the response.
            reader.Close ();
            dataStream.Close ();
            response.Close ();

Why do you make use of web services? You can then have WebApplication and a WebService

WebApplication can talk to the Webservice and get results by simply calling a function onte webservice,.

 in the WebApplication.MakePayment.aspx

Dim Result as boolean

Result = Webservice.payMethod(AmountToPay)

 If Result = false then

 'Sorry. payment failed



End if

thanks for your reply.

You might well be right and I might use a web service ,but i didnt know or see the use of it ,but before let me explain this a bit further.


Ability to support many payment Systems some like PayPal  etc and some that go via an Authorization provider but we provide the user interface.

These are built using a plugin architecture,i didnt mention this before as i didnt want to make things confusing.

Suppose we have 10 plugins= 10 payment systems ,

at the moment the user presses OK and wants to check out he will be presented with a webpage with 10 buttons if you like

Pay by Credit card, By Voucher ,Pay by Account ,Pay by PayPal etc......

when pressing the button I know which plugin it is and I have to redirect to a webpage that is customMade for that plugin.That page might or not be available.

I thought it would be a good idea to have a web App  eg ("MyCompany.ABCPaymentSystem.Web) and in it you will be presented with a page with a credit Card Control on it

Pay and be redirected back. 

Any suggestions or other way to achieve the same?

In the meantime can anybody suggest or provide an example on how to communicate between 2 web application?

Thanks again

How to use a web user control from one web app in another web app?
I have a production web app project (at work) that has custom web user controls in it.I have another web app project for experimenting and I want to use some web controls from the production web app. The big trick is that I need to load the controls dynamically.LoadControl() doesn't seem to work - it complains about loading controls from a different application.

How do I merge web services' app.config with web app's web.config? Help!!
I have a web application project that uses a separate class library containing web service references (service layer). I want to be able to configure the web reference URLs dynamically and I know you can set this up by setting the URL behavior to  'Dynamic', etc, etc. The problem is VS2005 puts the URLs in the project's app.config file.

Can WSE 3.0 Web Service be exposed to the web and can it be consumed by non .Net apps?
If I write a WSE 3.0 web service in .Net 2.0, can I expose it to the web like an IIS XML web service.?Also, can this web service be consumed by non .Net apps or .Net 1.1. apps?sun21170 Yes, simply enable your web service project for WSE 3, and this will alter web.config to support WSE 3 web services in IIS.The web service can be consumed by non .Net clients, however .Net 1.1 clients may struggle unless you add WSE support ans generate specific WSE proxies at the client end.  JamesMy Blog:
