CreateSubKey("SOFTWARE\\MYSOFTWARE\\DATA");

'\' followed by another character is a whitespace symbol. For example, you can define a tab("\t") and a new line("\n") with it. To get a \ character, use the backslash twice - '\\'.

it follow an error :

how to define CreateSubKey ??
and how can I set n get reg value

I made the command shorter to show more exactly where the problem is. Just use this:

RegistryKey ^ regkey = Registry::LocalMachine->CreateSubKey("SOFTWARE\\MYSOFTWARE\\DATA");
