After reading this guide (http://ozekisms.com/index.php?owpn=3...de/cpp-sms-api) about sending/receiving SMS messages using a C++ SMS API, I'm thinking about buying an SMS gateway. I just want to ask some questions.

1) Have you ever tried to build an SMS application in C++? This article provides an example program, but I'd like to check more. Can anybody show a demo for me?
2) Do you have any experience with Ozeki NG SMS Gateway?

Thanks for any answers!
