Paypal invoicing API with asp.net

[joanntan]

I am working with the paypal invoicing API, and have set a web reference to the location of the wsdl. Once I create an invoice using the CreateInvoiceRequest method, how do I go about sending the invoice to the API?I know that I could parse that information into an HTTP header, and send the information, but does visual studio create the helper classes needed to send the request to the web service when I add a web reference? Or maybe, does the API itself include a method to send the invoice request?Example Code:\[code\] imports PayPalInvoice 'reference to web service Dim request As New CreateInvoiceRequest request.invoice.dueDate = "11/12/12" request.invoice.itemList = itemlist ... 'all other information for the invoice request.invoice.logoUrl = "http://foo.com/logo.jpg" request.invoice.terms = "These are the terms"\[/code\]So, what do I do now to get the invoice to send to PayPal?Here is a link to the documentation for the API: https://cms.paypal.com/cms_content/US/en_US/files/developer/PP_InvoicingAPIGuide.pdf
