I have a very simple asp.net (vb) website that I would like users to subscribe to. The process is simple; there is no shopping cart and only 1 item. The logic is this:
1. User selects radiobutton of subscription term (1,3,6,12 months)
2. The total and taxes are computed
3. The user clicks the Pay with Paypal button and the expresscheckout is performed returning success or cancel.
4. If success, the expiry date of their subscription is incremented in my SQL DB.
Parts 1, 2 and 4 are done, I need help getting the expresscheckout working in vb.net. The project uses .Net 4.5. Most of the mechanics are there and I have a sandbox account already setup... just lacking some basic know-how.
