Solution 2

No difference, only they are different functions (and "void" must be lo-case; you code won't format) and "main" is not the entry point of executable assembly by default.

It's important to know, that the entry point does not have to be "Main". It can be any static method with on of the required signatures (http://www.csharphelp.com/2006/08/entry-point-in-c-program/[^]). If you are using Visual Studio, you can go to project's property and change the class where the entry point is supposed to be.

Expected your answer here. But wondering why people downvote for no reason. I don't think my compensation won't increase that vote level

Sergey Alexandrovich Kryukov 15-Mar-11 1:59am

It's OK, thank you.

That 1 was placed by a CP heavyweight - probably having a bad hair day :) - your reply is both nice and accurate ...

Sergey Alexandrovich Kryukov 15-Mar-11 13:12pm

I get "1" with heavy weight from time to time with no explanations. It's OK.
Thank you,

Well, I can't say I agree - you've made a pretty decent effort at answering most qustions, often developing small programs illustrating your points - anybody with this kind of weight on CP ought to respect that :)

Sergey Alexandrovich Kryukov 15-Mar-11 16:35pm

Well, I don't know the reason but I can guess. Some people are irritated with my sometimes eccentric and sometimes annoying manner (and often quite harsh, too, to be honest). Somebody openly express their irritation. Of course, a decent person should look only at the fact he or she is being evaluating at the moment, without regards to emotions. Some people cannot help being overly personal.

Anther thing is that some of my answers were absolutely mistaken. I admit it when I'm convinced I was not right. If someone gets this negative experience from me, he or she paid less attention for the matter of Answer and tried to vote assuming bad answer (driven by the past experience). I've done this mistake myself, hopefully fixed my votes.

Finally, some my answers are so unusual, that some people would take them for mistaken from the first glance. I know 2-3 cases when the truth is opposite to the common opinion, for example, in case of the error in documentation which wasn't checked it up.

Example: please look at this: don't you think this documentation clearly shows that a thread needs "new ThreadStart"? Look: http://msdn.microsoft.com/en-us/library/xx3ezzs2.aspx. This is how Microsoft explains it, but this is absolutely wrong. This fact can be proven not just by experiment (which is never a true proof), but by considering general rules for delegates instances. The person who was driven by the Microsoft documentation would find my code is mistaken. Interesting, isn't it? But natural.

So, there are some rational and irrational reasons for such down-voting.

To finish, I remembered a funny fact. Years ago I bought a book (professionally printed by an official book publishing house!) named "Thirty mistakes in Borland Object Pascal", in Russian. The author "proved" that he found 30 mistakes in the compiler. And what? I considered all 30 mistakes and disproved all of them! Some "mistakes" were like that: run this code: [sample], it works but in fact it should crash, compare: [sample in C]. You know...

Well, as far as I can see, most of those with "authority" above the 10K level has occasionally given vent to some frustration when it comes to answering questions.

So far the programming mistakes I've caught you at are those times you state that you where mistaken - I'll admit that I haven't read previous revisions, and there still is a few 100's that I haven't read - but then there is more than a 1000 to choose from.

So I think you've done a terrific job - as for "You know...", I guess I do :)

Thank you very much for this discussion and good words.
