    Or you could just do
    Code:
    for (unsigned int i = 0; i < valuesOfEnumerators_v_i.size(); i++)
    {
        try
        {
            EnumValue = EmumVec.at(i);
            if (! (EnumStream << EnumValue)) throw std::exception("Unable to parse input.");
            if (! (EnumStream >> EnumStr)) throw std::exception("Unable to extract input.");
        }
        catch (const std::exception& e)
        {
            std::cout << e.what() << "\nBits: eof: " << EnumStream.eof() << " bad: " << EnumStream.bad() << " fail: " << EnumStream.fail() << std::endl;
        }
    }
    Simple, short, yet concise and gets the work done.

    The thing is, I didn't want to use my debugger. I wanted to waste my time putting out a lot of verbose, useless debug information, just so I could annoy you. And it worked...
    True, and you wasted lots of time yourself.

    I use it all the time. That's why you see lots of posts with "Last edited by Programmer_P;"...
    But apparently you favor multiple posts when finding something new to add instead of merging them into one post.

    I know there is a multi-quote button. But sometimes I forget about it. Anyway, I don't see what the big deal is. Why are you so into multi-quote buttons?
    Maybe you should work on finding if it exists? The problem is that you double and triple post. A lot.
    Such things are frowned upon. I guess it isn't long now until you're going to quadraple post.

    The part in bold is really the most annoying part. I was continually reminded of 'How To Ask Questions The Smart Way'. Reading through that little guide is tremendously helpful.

    There is a super-saturation of truth in these statements. I expect crystalline formations to appear soon.
    If I did your homework for you, then you might pass your class without learning how to write a program like this. Then you might graduate and get your degree without learning how to write a program like this. You might become a professional programmer without knowing how to write a program like this. Someday you might work on a project with me without knowing how to write a program like this. Then I would have to do you serious bodily harm. - Jack Klein

    Hey, thanks for that link. The author of it definitely made some good points.
    I'll try to watch what I post a little better from now on...but seriously, its the Internet.
    Half of the time, I'm not even serious when I post stuff. Don't take it personal. Also don't think that I'm taking anything personal, because I'm not. Its just my personality to say things in a prickish way that always annoys people. That's more for amusement than anything else.
    And about the research/homework thing, I usually do do that before starting a thread (though I admit I maybe don't give it as much effort as I should). And right after discovering that the problem was with the stringstream, I read up on the stringstream << operator reference at cplusplus.com, but it didn't mention that it appended to existing data instead of replacing it. So I figured I would mention it here.
    Anyway, its funner to get feedback from real people on programming problems, rather than turning to Google all the time. Plus, getting involved in a discussion about the topic always helps me remember stuff better.
    I'm an alien from another world. Planet Earth is only my vacation home, and I'm not liking it.
