HOWEVER, it didn't work...go figure. I searched the net for a super long time, and finally found the solution. So I figured I would write it on here in a little more coherent fashion.
The original code (does not work!!!) is shown below:

In order to get the code to work you must add two lines, shown in bold (works!!!):

To call the API and make a direct payment, I used the call (in another aspx file):
Dim r As New GenerateCodeSOAP.DoDirectPayment
r.DoDirectPaymentCode("5.00", "Doe", "John", "123 Main St #1A", "", "Maintown", "MA", "01011", "Visa", "123456781234567", "999", 11, 2012, com.paypal.soap.api.PaymentActionCodeType.Sale)
