dll for posting credit card transactions

Enclosed is the source code from 6.0 for submitting credit card information. However, in .net, there is no XML component to use. Therefore, I need this one built. The website will always be the one as listed on the .open line. Need to have the following properties: 1. AccountNumber 2. CardNumber 3. ExpMonth 4. ExpYear 5. Total 6. Address 7. Zip 8. SecurityCode The securitycode will be the three digits that will goto the CVV2 part There will be a function called PostResults which will return the text If this was successful for the test one, then the exact response returned will be "YAUTH/TKT 019454","Address and Zip Code Do Not Match (N)" But you cannot hard code it though. Use the info from the included project for testing this. This needs to be a .net assembly with no references to COM at all and needs to be completed with VB.net. Let me know if you have any questions. ## Deliverables The compiled dll and the source code for the dll. ## Platform Windows 2003 Server Edition.
