Newbie subclassing and header question

[cypherzero]

I've defined a subclass of std::string in 'mstring.h' and the main program in 'main.cpp'

mstring.h contains the full class definition (as follows) and main.cpp contains an #include "mstring.h" command, yet I recieve over 100 errors telling me theres no such class as MSTRING. I feel I am doing something very simple very wrong, can anyone spot the mistake!?

Thanks in advance.

///////////////
// mstring.h //

class MSTRING : public std::string
    {
    public:
        bool contains(MSTRING txt)
            {
            if (txt.empty())
                return true;
            else
                return (this->lcase().find(txt.lcase()) != npos);
            }

        MSTRING lcase(MSTRING i)
            {
            MSTRING r(i);
            std::transform(r.begin(), r.end(), r.begin(), tolower);
            return r;
            }

        . . . more code . . .
    }

Could you post the errors please?

[cypherzero]

The errors are all of the type

MSTRING rfilter;
// error C2146: syntax error : missing ';' before identifier 'rfilter'

or similar, suggesting that the class hasn't been identified.

What did you put after the last right curly bracket of your class in your .h file?

kind regards,

Ok, sorry, I found the error -
A ';' was needed at the end of the class definition.

Just read your reply as well - that would be it =o)
Cheers

It is a nasty little beginners' error; now you know the syntax for the rest of your
life ;-)

kind regards,
