Anyone can give me hint how to do this project?

Very simple homework assignment. If this is too difficult for you to even make an attempt at then I would suggest you learn the phrase "Would you like fried with that".

This is not a forum where we supply code for you without seeing any effort as to what you have attempted so far. If you attempt something and have a place where you are stuck, you can show us where you are stuck and then we can try to help you. I strongly suggest reading your book where it talks about Macros so you can get a better understanding what is required of you. Hints will not be supplied here.

Who told you such a stupid thing that attendance control is vital?

I got education in the university where tracking of attendance was considered indecent by most parties, and attendance was considered free of control, at least de-facto. Students were considered adults who knows that not paying attention at lectures and in classes only steal from themselves. We simply have very hard examinations, and those who were not successful enough for some extended period of time, were expelled without too much sentiment. It really works. When it comes to adult young people, everything else is not real education, just a waste of resources.

In my country i would say: strong words! Is it equal sentence in english?
My virtual 5!

Thank you, Maciej.

By the way, how you spell it in Polish? Most likely, I will be able to recognize the Polish morphemes, because they combine Slavic and/or Germanic etymology, which I partly know from Russian/Ukrainian/English.

Yes, something like that, but not "equal": in English (I'm more familiar with American English; hope knowledgeable native English speakers can confirm it), "strong language" means using offensive, swearing, foul, dirty/vulgar words. I hope this is not what I do. :-)

Please see:
http://en.wikipedia.org/wiki/Strong_language

I think this Polish usage is closer to Russian, as people might say "крепко сказано" (told strongly, where "strong" means robustness, "undestructiveness") or even "изрядно сказано" (told in outstanding way, "изрядно" (derived from "out of the row", that is, "outstanding") is very archaic but still used in style).
I hope this is what I do... :-)

Yes, Polish usage is closer to Russian. I know the meaning of sentence "strong language". That's way i asking about correct usage. ;)
So, "told strongly" or "told well" is what i mean.

Thank you, Sergey.

That simply means that your feedback to my post was very positive, as I hoped to understand it. :-)
So, how do you spell it in Polish (please see my edited comment above)?
Thank you very much,

Direct translation:
dobrze powiedziane - хорошо сказано
mocne słowa - сильные слова
Meaning: Perfect answer!

Well, almost all clear:

"Donrze" is добре (Russian dialect, Ukranian used only as communion ("agree, deal"), not adj, more neutral is "добрый" (good, including the sense of "good quality")).

"Mocne" is "мощный", "мощные" (powerful); "słowa" is literally the same, слова (words).

"Powiedziane" is less obvious. Maybe "wiedz" is something derivative from our common root, something like "весть" ("message", in higher or older style); we also have related root "веж..." (being aware of), "вежливый" (polite, as in Russian "polite" is derived from "aware of", that is, not ignorant, knowing how to deal with people properly, while Western "polite" is related to being a citizen: "politia", "police" => "politics"). Here I'm less sure; how do you think, do you see such relationships?

Nice exercise anyway, I really like such things.
Thank you very much.
