Hi Ashley,
so, as I understand it, your program is spawning a browser window, and passing some parameters to paypal. The user then interacts with the browser window - filling in all their details etc.
Am I right so far.
Of then the user clicks on "submit" and the payment goes through. At this point something then appears in the browser? What that something is, is the URL that you specified. since it's your URL you will need it to be a web page that you can serve - either something added to your existing we site, or perhaps a new web app.
>> And would one still get the PageReceived info from the post?
If you are simulating the whole browser experience via your program, using the NetWebclient, then I guess there will be a number of steps you will need to automate. You'll get back everything from the server, ending finally with an instruction to "redirect" to your thank-you URL.
But I expect there's a fair bit of interaction before then.
cheers
Bruce
