Sorry, the second version sucks, because: 1. It's completely incompatible with previous versions. 2. I cannot write production code with it: it's still beta. There's no way I will use a buggy beta version on a production system. It's not even a "Release Candidate" (aka "feature freeze version") yet, so all the features can change, and there's no way to assure that even the sample you showed will work on the final version. Press "Next" two or three times on CP and you'll see someone complaining about the IDE deleting code. This could lead to really subtle bugs. BTW, could you please post a version of your example that compiles on VS.NET 2003, so that we could compare C# with something that compiles with the current version of C++ on .NET? I see dead pixels Yes, even I am blogging now!

You don't even need to use the new operator for reference types? Like
StreamReader^ r = new StreamReader(...);
I do understand RAII and that StreamReader's destructor will serve the purpose of Dispose but not calling new for a reference type seems kinda weird to me. Particularly since in C++ (pure C++), your code will create an instance of r on the stack and new StreamReader will create one on the heap. In your case, r will be created on the managed heap and won't be deallocated till it gets GC'ed, right? Regards Senthil _____________________________ My Blog | My Articles | WinMacro

Yep :) The key point here is to distinguish between object destruction and memory reclamation. We are used to think that these two things happen at the same time, but it is not really a necessity. In this sample,
rhas stack semantics and it is irrelevant that memory really comes from GC heap, and that it will be reclaimed in non-deterministic future. The object is destroyed (meaning - the destructor is called) at the and of scope, and that's the point.

I was expecting this question. Because we're talking about language features here, using external files is cheating: you either include it, or you'll need to accept that C# has natural language processing features: NaturalLanguage.English.Process(sr.ReadLine()); Now, you just need to search the web and find some NLP library and I'll prove it to you.

Toasty0 wrote: Maybe it is fun to be a C++ developer, and a blast from the past to work with legacy code, but it cain't be fun earning less than them managed code guys. You are contradicting yourself. You talk about managed C++ for .NET and then talk about earning less than the managed code guys. Managed C++ is managed code. If you mean C++ in general earning less than managed code guys then you're comparing apples to oranges. Your head hunter's pamphlet talks about .NET developers. There's a whole world out there that doesn't care about .NET. (I'd venture a guess that it's the vast majority of the programming world) There are millions of embedded system developers, game programmers, scientific developers, kiosk terminal developers real-time critical application developers and on and on who still program in C, assembler and C++ (among other languages). .NET isn't anywhere on their horizon and likely never will be. A recent CP poll is a good example of this: of the millions and millions of mobile phones out there, how many use .NET? Very, very few (if any). I think the reason you can make a good living programming for .NET is that many educational institutions don't even teach it yet; competition is scarce. About 18 months ago I hired a .NET developer for a mapping extension we were building. Not a single applicant had any experience with .NET despite the presence of a very good college (now a university) in town with a computer science program! The fellow I ended up hiring had worked with Delphi programming real-time GPS related code. Did I care about .NET? Not really. Learning languages and frameworks is fairly easy compared to learning about GIS, GPS, mapping projections and GIS frameworks. He transitioned to C# fairly quickly. Earning money in a programming field is not just dependent on the programming languages you work with; your knowledge of the industry's specifics is just as, if not more, important. My 2c. Cheers, Drew.

Daniel Turini wrote: Because we're talking about language features here, using external files is cheating: Not exactly. With C++ you can find a library that would produce the effect we were talking about, because C++ has language features (in this case templates and "__nogc" classes) that make this library possible. With C#, you can't find such a library because the language does not offer capabilities to make it (and believe me, I have tried). That's why C++ is a better language than C#: it offers more capabilities and puts less restrictions on libraries' writers.

Because the federal government has not fully adopted C#, in fact C++ was only "recently" adopted, Ada requirements only died out a few years ago, and I have seen "new" stuff written for fortran only 4 years ago. .Net will be a tough one to convince someone to adopt 100% in US federal architectures. So a few of those "die hard" C++ users carry some massively big bucks to keep C++ alive and kicking.

sure it's not used that commonly anymore but what about game devs ? they use mostly C/C++ and that's a huge industry with f$%!loads of money in it. besides that, there are still a few places where C++ is used almost exclusively (OS/Kernel development, industrial strength graphics, etc etc) it aint just for fun(!) and legacy stuff. also, weren't java devs paid alot more than most a few years back ? :-D
Ummm...I think you're missing the point which is Managed c++ vs c#, NOT c++ versus c#. Game devs can use whatever the hell they want, but it's unlikely to be .net based is it?

As far as I can see, the "converts" were using C++ for wrong purpose anyway (form based, business data-centric apps). They should have switched to VB long time ago. VB6 is perfect for this kind of development, IMHO better than .NET.
