    int main(int argc, char *argv[])

    Re: Assigning Member Name from String

    Right, ok, thanks guys, I'll think about using CMap next time if I absolutely have to link a variable to a string, but where possible will avoid it, very useful to know, cheers.

    Re: Assigning Member Name from String

    Re: Assigning Member Name from String

    Victor, you're quite right, your way of defining the way is how I should do it rather than the quick fix I described - I took the idea of a "quick" fix too literally and didn't think to simply define...

    Re: Assigning Member Name from String

    Of course! Why didn't I think of that?!

    I've created an array of pens, however VS doesn't like me setting the array as:
