PayPal Integration with .net (to get values back from PayPal)

 We want to integrate our ASP.Net webapplicaiton to PayPal. Currently we are in teh process of developing the application so we are using PayPal sandbox. When user clicks on checkout button we pass the control to paypal sandbox, where the items along with their price is displayed. Now suppose user pays for the items, now control should come back to the main application along with the information whether payment was successful or not and also the transaction id (which we need to put in our database). Please let me know how we can do this. Also, do we need a public ip so that sandbox can send the control back to the main application. Currently the application is under development so not deplyed on any servers with external ips.

Paypal's SDK kit for ASP.Net may be a good start. There are instructions, documentation and sample code available on that site.

Converting classic to .NET 2 code, and .NET gets an error back from ADS?
 For future-proofing, our Internal Phone Directory is being moved onto our AD servers, and obviously we're using LDAP for queries.To get the phoneboook queries working, I adapted the current classic ASP code to use LDAP, and that works fine. However, we're wanting to move these pages to .NET, and that's where the problem comes in. Using the same basic logic from the Classic code (90% of its unchanged) to produce an LDAP query, I get the error  155 Unknown error (0x80005000)This is using the same website, and so the same credentials  - unless aspx pages run und...

Getting started with JScript.NET
I'm a Javascript and Actionscript developer, and the thought of being able to do server-sides in something I know was too good to resist. Does anyone know some good tutorials for developing ASP.NET pages in JScript?  I can find lots of console code, but simple things are hard: like I can't even figure out how to print something out to the web page (just a string). What I'm really trying to do is access a database, verify a login, and print JSON out to the response.  What should I do to start?  Is there a better way to do this? (IE: using some JSON library already?). I'm commun...

Hi, I'm at a loss to explain this... I have an ASPX page that I can't always navigate to. When I developed the app (it's Starter Kit Portal-based), I did it on my LAN and have had no trouble accessing the page. However, upon deployment, I see the following behavior: 1. POST request goes out looking for MyForm.aspx 2. GET request for MyForm.aspx 3. GET request for MyForm.aspx 4. ... X. GET request Sometimes, the page finally loads. Other times, it just ends up blank. Many times, it doesn't load at ALL the first POST - I just get a "The pa...

I'm playing around with fetching things from the CPAN shell here. We have an FTP and an HTTP proxy here. While stepping through things in the debugger, I notice that Net::FTP::new loads $fire from $arg{Firewall} || $ENV{FTP_FIREWALL} || $NetConfig{ftp_firewall} || undef; $fire_type is initialised similarly but %NetConfig is not consulted.
