Website Payments Pro (PayPal) w/ ASP.NET Sample App

ASP.NET Sample app to demonstrate Integration of Website Payment Pro for (US) . Information can be found at [login to view URL] We need to process credit /debit cards on our website or at least be able to accept PayPal transactions. User should **not be transferred** to Paypal site and we will process the transaction at background (I would prefer SOAP or NVP API call). This code will be included within another application so you can just include the response (accepted or denied) as field label after hitting submit. It is important that the form not be redirected though. The code must be written for ASP.NET sample .aspx page in VB. The code (if possible) should use simple string concatenation to send to the system for processing (example: &Firstname=Eric&LastName=test&ZipCode=5555) etc... Note: Please do not just create an applicatino that generates a URL and redirects to PayPal. This must use the Website Payments Pro from PayPal.
