Seriously? You are writing a program and you do not know what language or framework you are using? I don't know how you expect us to help if you cannot answer such a basic question. I would suggest you make a decision which language you plan to use and get hold of a book to learn the basics of it before trying anything else.
All I ask for, is that you write one line of code with my own data in C++.
No, you have not asked that, you asked how to get a number formatted in a particular way in C++/CLI, and I referred you to the documentation that explains it in detail, with plenty of samples. It seems you are not prepared to spend the time reading it. You also do not seem to know exactly which language you are using, so I cannot answer the question, because it would be different for each language.

Neither did I blame you for anything. I have done my best to help you but I cannot answer the question unless I get the proper facts to start with. As I said before, you need to decide which version of the language you are using and start studying it. Give us the proper facts and background to your problem and we will try to help, but you are expected to do some of the work for yourself.
