    Study on the quality of software interfaces

    Dear Forum,

    I'm trying to rate the quality of software interfaces and am looking for
    participants for my code-based online survey. As a motiviation to
    participate, a 50 Euro Amazon gift coupon will be drawn. The survey
    takes about 10 minutes to be filled out (maybe a bit longer for
    unexperienced programers). Nevertheless, experienced as well as new
    programers are asked to participate. Code examples are provided in C++, but
    even if it might not be your favorite language, your participation would be highly
    appreciated as the study handles these problems (and even benefits from it). The
    survey is anonymous (except for your e-mail address which is required for the
    coupon) and serves my (hopefully independent) research question.

    The link is:
    study

    The survey will end on 1/31/08.

    Thanx kermi3 for allwowing me to post this here.

    Many thanks and best regards,

    -Dirk

    I didn't get past question 2. Why are the radiobuttons not set to a default to begin with if they all need to have a value (or why wouldn't you let people tick checkboxes)? Not good interface...
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.
    Quoted more than 1000 times (I hope).

    Some style notes:

    Pupils and students are the same thing.

    It's rather redundant to qualify a drop-down menu with "choose only one of the following".

    "Qt" is a GUI toolkit made by Nokia. "QT" is a video codec made by Apple.

    The first example contains an error: the class is called Win_Example_Window, but the OnLButtonDown implementation is for a class called Win_Tutorial_Window.

    That's why I called that one "difficult to follow" and flagged it as "important info missing" and "extra steps included" (or whatever it was).

    HTML isn't really a programming language.

    Code:
    #include <win.h>
    Should that be windows.h?

    I would suggest running the study for more than just a few days . . . I mean, it ends tomorrow! I'd give it a week at least. Some internet users have a weekly cycle. (Like me.) If you do the survery for a week, you'll catch the people who only go online on Tuesdays etc.

    Some of the questions are negative -- "Code is not understandable at all" -- and some are positive -- "There are unneeded intermediate steps". If I didn't understand the code at all, I'd have to click yes for some questions and no for others. I'd change that if possible.

    The code is not of the best standard in many ways, and most of it wouldn't even compile. Count the quotes here.
    Code:
    cerr<<argv[0]<<":can't open'"<<refFile<<"':"
    [edit] Just realized that the quotes were intentional. It didn't look it in the original font. Perhaps a monospace font would be a good idea. [/edit]

    Why is there a semicolon after the closing brace in main() for question 5? Indentation is inconsistent (watch out for Elysia!) -- some lines have several statements. etc, etc.

    Should that be windows.h?
    Nah, that's <afxwin.h>, actually. It's the MFC example.

    Well, whatever -- I was pretty sure that <win.h> wasn't right. Shows how much I know about MFC.

    Well, it's sorta anonymized. The class is called CFrameWnd and not WinFrameWnd, and so on. Happened for all the libraries. Qt became R. .Net became NWin or something like that. COM became Bo. I forgot the codename for CORBA. MFC simply became Win.

    It's probably a legal thing. Because if it's an attempt to keep us from recognizing the libraries and making judgements from prior experience with them, it's a pathetic one.

    MFC Sux!

    Sorry couldnt help it. Had to give my boss a lecture today on why MFC sucks. He was implying that MFC would have been better for 'The Big Huge App' because one little feature (a slider bar) would have been easier to implement. I had to explain to him that the other 99% of the application woudl have taken 3 times as logn and run half as fast, not to mention that half the custom libraries we are using would have to be rewritten from scratch.
    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.

    I think abachler meant "long", not "log(n)"

    Wow, thank you all for the feedback! I will take your suggestions for improvement into regard.
    By the way: you can still participate in the survey, we have extended the time limit to Feb, 5th 2008 .
