C# / VB.NET Paypal Response
Hi.
I've found some code on the internet that is used for updating my database after customers haev paid via paypal on my site.
The variables all send to paypal ok, and seem to send back i think, but i cant get this code working i have found.
I wanted a C# one, but could only get a VB one that looked good, but is generating some errors.
Warning 1 variable 'response' conflicts with property 'response' in the base class 'Page' and should be declared 'Shadows'. OnlineAccounts\Paid.aspx.v
Error 5 Type 'IBuySpy.TransactionDB' is not defined. OnlineAccounts\Paid.aspx.v
