The sample code returns ACK, but where is the proper response?
For example
Getbalance, sample code returns ACK

but the document shows it returns other values?

I was having trouble getting my shopping cart to connect to paypal. So I wrote a simple webform that has one button and one label. If I comment out the response.redirect(url) and look at the content that get written to Lable1.Text it looks find. Also, if I copy the content of the label and paste it into my web browser it goes to Paypal and displays correctly.
However, if I uncomment the response.redirect(url) I get the following error: ERROR: Unable to Send to PayPal - Thread was being aborted.
I am testing from localhost??? Should I be able to test this from localhost?
I have put ??? where my Sandbox email address is.....I don't know if letting other see that or not is an issue....otherwise I would have left it in for someone to try this code.
[Code]....
This is what displays in the lable1.text when response.redirect is commented out

I am developing a website with online payment. Payment is done using Paypal NVP Api. There is need of a facility to store customers credit card details(not in database) once they register to Website.There onwards whenever they order these details will be fetched, Customer need not enter their card details for every order. So is there any facility to create a profile n store credit card details of customer, as it is there for recurring payments?

There is a link in paypal page called "Return to Merchant Test Score" and when user click on the link it redirects to my Thanks.aspx where I fetch the response and if verified the update the database.
But my problem is that If after successful paymet user not click the "Return to Merchat Test Score" and directly close the browser then it not update my database.

I've got the first two stages (the calls to SetExpressCheckout and GetExpressCheckoutDetails) but CreateRecurringPaymentsProfile fails with the error below. I'm using a modified version of Paypal's sample code, but I suspect I'm (not) setting an encoder value. Anyone used this before? The error:

// but paymentSuccess is false
