Paypal integration dotnetnuke module


I am a ASP.Net Programmer , working with DNN 3.2.

I am trying to integrate the paypal  in my module for purchasing item
I want to notify user with mail about the money transaction whether it is verified or not..
And have to do some changes in database if only the money transaction is verified.

I have written the paypalstring statement as

Dim sBaseURL As String = sDomain & IIf(Request.ApplicationPath = "/", "", Request.ApplicationPath).ToString & "/DesktopModules/PayPalIPN"
                    Dim strPayPalURL As String = ""
                    strPayPalURL = "" & HTTPPOSTEncode(strProcessorUserId)
                    strPayPalURL += "&item_name=" & HTTPPOSTEncode(strProductName)
                    strPayPalURL += "&item_number=" & ModuleId
                    strPayPalURL += "&quantity=" & HTTPPOSTEncode(txtQty.Text)
                    strPayPalURL += "&custom=" & HTTPPOSTEncode(Context.User.Identity.Name)
                    strPayPalURL += "&amount=" & HTTPPOSTEncode(lblProductCost.Text)
                    strPayPalURL += "&currency_code=" & HTTPPOSTEncode(lblTotalCurrency.Text)
                    strPayPalURL += "&return=" & HTTPPOSTEncode(Settings("SuccessURL").ToString)
                    strPayPalURL += "&cancel_return=" & HTTPPOSTEncode(Settings("FailedURL").ToString)
                    strPayPalURL += "&notify_url=" & HTTPPOSTEncode(sBaseURL & "/PaymentNotify.aspx")
                    strPayPalURL += "&undefined_quantity=0&no_note=1&no_shipping="
                    If Settings("Shipping").ToString <> "" Then
                        strPayPalURL = strPayPalURL & "0&shipping=" & lblShippingTotalCost.Text
                        strPayPalURL += "1"
                    End If
                    ' redirect to PayPal

And in notify_url=PaymentNotify.aspx I am verifying the valid transaction and doing db changes..

But somehow it is not going through PaymentNotify.aspx or you can say the values in db are not changing

Can anybody tell me where I am getting wrong?

Please help me

Thanks in advance,

What you need is to have a page for the Notify_url to go to.

Your code above will be looking for the page in your root dnn install (same as the default.aspx).

All the Notify URL does is provides a method for PayPal to hook back into your website.

Once this page is called from PP, you will need to so some thing in the code behind to acheive the actions you are after.

Hope this Helps,

DotNetNuke integration.
 DotNetNuke has grown into an very attractive web application developement framework.Jus take a look at the standard modules list. You even have an extranet feature with optional  Active Directory integrationIs anyone considering/has done any integration of this classifiled wih dotnetNuke 4.0?  Thanks/Kadji   Yes Kadji,This would be a fantastic idea. But i do not think hat woule be much simpler. It would be rather more tough than expected at first sight. The framework of DNN is very different that our framework 2.0. This DNN should be run above the framework and this works as modules.lot many things would have to be change to make it work with DNN. This can be done only by some genuis and at this stage i am not a genius to do it myself.Incorporating AJAX would also be a nice idea. Specially while raeding an ADVT, if some one clicks on the photograph. The photo should be seen immedately as zoom, rather than downloading/refreshing the page again. AJAX can be used in many places in Classified.But still i an not an expert with AJAX also. Hoewever i juist had my new book on AJAX with ASP.NET 2.0 for reading.Finally AJAX and DNN is a GREAT way to go for Classifieds. Classifieds is the most Booming business around and will stay for long.ThanksPaggy4uPaggy4u-----------------------------------------Working with Dynamic Languages  DotNetNuke 4.0 works on .Net 2.0. I will work on a integrating classifield as a module in .NetNuke. 4.0 Th...

What Module is using for DNN3 modules?
The module used for the 3rd party DotNetNuke3 Modules is nice (needs a lot of improvement still, but worlds beyond what is "stock" ), and I would certainly like the opportunity to play with it a bit and consider it for my sites, however I can't figure out what they are using! Shawn: When you use a third party module on the dotnetnuke site, you should probably add a tag line IDing it to the bottom of it so that the rest of us can check it out! Thanks. That is Patrick Santry's Resource Directory Manager. I'm not sure what Patrick's plan are with this module in the future or ...
