Speaking about the timer I ment something like that:

typedef int milliseconds;

class stopwatch
{
public:
    stopwatch()
        : started_(::GetTickCount())
    {}

    milliseconds elapsed() const
    {
        return ::GetTickCount() - started_;
    }

private:
    const DWORD started_;
};

Agree.
