VB.NET and Paypal Shopping Cart

Hi folks,
I'm doing a page for a person, and they want to use paypal as the shopping cart / processing vendor. I've read alot about it, and all that I find talks about how to make it work on the HTML side of it (client side). My thing is, I have to pass dynamic values to the cart (all determined on the server side). Has anyone ever done anything with paypal shopping cart and VB.NET. I'm thinking that I need to have a backend method that I can pass the dynamic values to, which in turn will send to paypal.

Anyone have any ideas?

paypal has an sdk you can download and use free of charge (i think). goto paypal.com and check it out. I've downloaded it but never played with it. Basically, it's just a set of class to use in your web apps or desktop apps that interface directly with paypal's databases. eBay has one as well free for the taking (unless you go commercial with it)

I've tried downloading their SDK. But i'm unable to find the download (maybe i'm a moron). I go the the paypal site (www.paypal.com/sdk), it talks about it, it has code examples, but no msi for download. Do you happen to have a link or even can you post what you have online somwhere so i can download it?


Thanks
