How do I download the videos?
- To download, right click the file type you would like and pick “Save target as…” or “Save link as…”
Why should I download videos from Channel9?
- It's an easy way to save the videos you like locally.
- You can save the videos in order to watch them offline.
- If all you want is to hear the audio, you can download the MP3!
Which version should I choose?
- If you want to view the video on your PC, Xbox or Media Center, download the High Quality WMV file (this is the highest quality version we have available).
- If you'd like a lower bitrate version, to reduce the download time or cost, then choose the Medium Quality WMV file.
- If you have a Zune, WP7, iPhone, iPad, or iPod device, choose the low or medium MP4 file.
- If you just want to hear the audio of the video, choose the MP3 file.
Right click “Save as…”
- Mid Quality WMV (Lo-band, Mobile)
- WMV (WMV Video)
Ale Contenti is a Senior Development Lead on the VC++ team. He works primarily on Safe Libraries and associated constructs. Here, we learn about what's new in VC SL (checked iterators are certainly cool - and fast too), things to think about in terms of
writing "safe" C++, future thinking in this area, and how to write a useful and performant C++ program without using pointers explicitly.
VC++ continues to evolve...
Enjoy.

policy is code non grata. reasons are code bloat, reliance on advanced compiler features, debug build performance, memory allocation patterns, complexity of code, and that it's a loaded gun for less experienced coders.
Others on the team have worked with STL effectively on previous projects however, by using custom allocators. Especially for things like strings, where the thing will fragment like hell if you don't.
Also problems I have found is that different STL implementations on non-microsoft based platforms in the past have been less than optimal, and it very much changes on a per platform basis. The reality is when your working at a game studio, some console providers don't have the great support Microsoft do with tools etc.
Hi lantree,
I agree with you. I really think C++ in general (and STL as an example of a powerful C++ library) has a lot to offer in environment like the one you work on. You just mention one great example when talking about custom allocators for memory management.
Few other languages let you control memory in such a fine, elegant and expansible way. Reading your post, I remembered one talk from Alexandrescu (Chromed Metal: C++ Idioms that Are Safe and Fast, I guess this paper covers some of it http://www.erdani.org/publications/cuj-2005-12.pdf) and one from Scott Meyers (When C++ Hits the Hardware, http://www.aristeia.com/short-courses.html#wchth) which describe interesting solutions.
As we say in the video, C++ is powerful and somewhat dangerous, in the sense that it lets you do a lot of things (and some bad things as well, if you're not careful
). With checked iterators, we tried to make the iterators less dangerous, without sacrifying
performance.
I'd like to hear from you more specific scenarios where we could do a better job in harnessing the power of C++. Do you need some pre-packaged allocator to simplify memory management? Do you need tools to measure code bloat? Please let us know!
One question: What do you mean with code complexety? You mean code complexity in the STL itself, or using it?
Unfortunately, we can't control the STL implementations of other vendors. Anyway, please note that we get our STL implementation from dinkumware (www.dinkumware.com), and they support more platform than VC++ does, I believe. Also, let us know which platform you need support on... you never know... (maybe we have a compiler in the box you can use...
)
And have you tried using VC++ IDE to drive your compilers?
Thx for your comments!

Hello
Ale and Louis (Lafreniere) recently recorded the follow-up channel 9 video to this one - Ale Contenti and Louis Lafreniere: Understanding Exceptions and When/How to Handle Them, you can view the video at: http://channel9.msdn.com/Showpost.aspx?postid=343189
Thanks Damien
