Your videos are clear and easy to understand. In fact your tutorials including this video helped me pass the technical interviews in one of the biggest investment bank in UK. Thanks a lot.

[@Mensana88]

Decent video, but you failed to explain the concept of the state of the event. That is the Boolean flag passed to the constructor of the event. The threads will not block on WaitOne if the event is in the "Set" state. The difference between ManualResetEvent and AutoResetEvent is that the auto kind will revert back to a "Reset" state automatically after being unblocked by a "Set" call. The manual will not revert back, but will keep its "Set" state until someone resets it manually.

I have been programming in .NET for 3 years yet threading still is a bitch. Spawning threads is easy. Managing them and invoking safely is harder. This video helped me understand perfectly. Usually I resort to MSDN but that documentation was too complex for me.

[@DimmuBorgiry]

great explanation. thank you very much

[@igorkuliev8357]

Thanks for the clear explanation!

[@wrght2002]

[@rupeshkamble9105]

Great video

[@vrajeshbadgujar]

Helpful! Thanks

[@anun3105]

Well explained. One query regarding autoreset event. Once set is called, threads will not be blocked even if Waitone called again. So how could we block the thread if required?

[@DavidAlexandru11]

Hello and thanks for this awesome video.
I have a question about how to call objAuto.Set() from another class. If I call from same class work perfectly.
Thanks again

[@kohlismunishk]

I hardly go to my Facebook account but still I shared. But let me tell you the work which you are doing have cleared so many confusing things and concepts, I was struggling initially. I am pretty sure the way you explain and I can see force in your voice and thoughts, it will not get un-noticed. I am actually going to buy your video set. One question: Will you keep on working on new MS technologies for example VS 2012. Do you have anything in that?

[@krishnadeshpande2570]

Superb video!!! Kindly keep posting !!!

[@nguyentrananhnguyen7900]

[@tyrellwreleck4226]

The way you pronounce "ordinary" is so freaking cool. By the way, very well elaborated metaphor about their difference. Thumbs up.

[@PaoYong]

[@yt.arunthakur]

marvelous work of piece :) thanks

[@avishcheetaram1807]

Finally understood. Thanks so much.

[@IchbinChandra]

Sir,
At 0:58 it was stated that Thread 2 is sending signal to wait, but as per what I understood is Thread 2 never send signal to wait, but Thread 1 itself decide to wait until Thread 2 signals to start again.
So basically we can only raise signal to start, but we cannot signal to wait.

[@mohdamircaet]

I also thought the same at the very beginning of the video, when he said that T2 will signal to wait for T1. This is wrong. And I used to like his videos when I was in college,but as I learnt things as a software professional, I have observed that all the videos of shiv are wrong, he gives wrong examples and bad theory,which might attract students, but conceptually he is always wrong.

[@TarunKomma]

MOHD AMIR exactly my thoughts 👍🏼

[@orochinagi1111]

great video..! really liked the turnstyle definition in the end

[@vd853]

Why not just use one waitOne() for autoresetevent instead of using manualresetevent?

[@AlekseyFilippovHuzzah]

God bless you in Jesus name! That is really cool!

[@suckinDiesel44]

Nicely explained my friend.
