Can anyone help?

I am currently following NeHe's course on the main page and i want to write mails to him asking some questions ^.^...but i can't find his e-mail address anywhere. Can anyone tell me his e-mail address?
Not that I know from experience, I've never tried to contact him, but he's probably a busy fellow. You'll have better luck (or at worst, just as good) posting your questions here -- there are plenty of knowledgeable people who are familiar with the tutorials who can help you out.

Oh, i am under the project of creating a firework scene, anyone can give me the source code of a nice firework scene? (with sound effect)
Thanks alot :)
Thanks alot :)
nehe is run and maintained by gamedev.net now, they have formed a group that is working on updating the tutorials.
if you have questions that is what this section of the forum is for.
post and we will reply.

You have presented your question as:
Problem: Make a firework scene
Solution: Can you do it for me?
No-one is going to build your project for you - however, if you have a specific part of the project that is troubling you, I'm sure if you ask a specific question you will receive answers.
Sorry to sound rude, but you need to learn how to ask questions.

No no, ofcourse i am not asking for anyone to do it for me, i am doing a project and i will do it myself for my own sake, i just want to see an example of a fireworks program (the code with comments is better :( ) so that i will know what i have to do, so i am just asking if anyone is having or knows where i can find a good example of it.
Thanks alot :)
Thanks alot :)
ok, I think what you're looking for is a tutorial on particle systems.
Once you understand how to make your own particle system (they can be pretty simple), you can use one to make fancy fireworks quite easily.
A 10 second google search found these - I havent read them in detail so I dont know if they're quite what you need, but theyre a starting point.

Take a look at lessons 09, 19 and 39.
These lessons describe pretty much everything you need to know to make a physics based particle engine, and with that you can make a nice firework scene

Oh, thank you very much and i have already learned lessons 9 and 19 today. I think i understand clearly how the particle system works (thanks to NeHe clear comments :) ).....but there is still one thing troubling me and i wish someone here will tell me how to do it:
-It maybe stupid of me to ask this but because i just started learning openGL 2 days ago so please be patient with this noob ^.^: i know how to make an explosion of firework now but i dont know how to creat some random fireworks going from the bottom of the screen and then explode at a random time.
-I dont know how to make the fireworks blow into some certain shapes (like ring or sphere), the only thing i know is random explosion ^.^.
Thanks much for helping me. (and please dont be angry if i asked stupid questions)

Remember: there are no stupid questions! (well perhaps there are some...[wink])
You have to structure your fireworks (best way is OOP, hope you're familiar with that) like classes for different kinds of rockets, then differ the direction in which you shoot a bit using the rand() function (see http://www.cppreference.com/stdother/rand.html). Each rocket class has to contain a particle system which explodes at a time you can get using rand() again.
Different shapes are created using different settings in your particle explosion.
Give the particles a fixed speed and generate a random direcion using something like
just emit particles within the first few frames to get a ring.
