Ratio of VC/C & VB

Everyone knows C++ has performance advantage over VB (at least up to VB6). The use of pointers is one of the best feature of C++ (note: C does not support pointer right?). It is fast and really saves memory. Also, being able to be in control of every single line that you typed in is also a big plus for C/C++. And since Windows is based on C++ (and Assembly) gives C++ another advantage especially with data types and calling conventions.

But that does not mean VB is lame. VB does have quite a few advantages that really makes a life as a programmer seems more enjoyable. RAD is the biggest selling point of VB and you gotta admit it, it is true. Of course, in making it easy to use, it has to hide few lines of code (well .. not a few but a lot). Sometimes, we do need to use those hidden lines but .... :(

I do miss my time being with VC++ and once in a while I do go back to it when it comes to work with those "complicated" APIs that require something that VB can't handle. But with the light of VB.NET, I think I'll use C++ even less :)

-Cool Bizs

:D Heh heh heh! Well, Fiery pal.......some programmers still use C cos' of traditional reasons. They think it's the only language created by God Himself. That's why!

On the other hand, some programmers, including those electrical engineers(those hardware developers), have to code their stuff in C. From what I know, those 82501 micro-controllers(if I remember correctly) requires the use of C. C++ isn't suitable.
That's why! :)

And no.......VB isn't lame. It's just that it's used for general purposes. But on the other hand, I hope VB.net isn't gonna surpass Visual C++ or anything. If it does, my C++ pals.......let's all carry rocket launchers and visit Bill Ga........u get the idea. :rolleyes: :rolleyes: :mad: :D

Please, tell me you're joking. Right?

I can't believe how many posters appear to have no idea of what they are doing. Pointers are one of the most fundamental concepts of C/C++ programming.

I'd rate the C/C++ competance of anyone who doesn't understand their use at somewhere between low and non-existent. Certainly below the minimum level for employment.

You should have all of the above.

I have experience with VC++/C and VB.

I orgionally joined this fourm for the C++, but the Java section has become more usefull to me. My Language of choice has changed.

Anyways, for my question: why use C when you can use C++? I don't understand. Isn't C++ just an extension of C? Then C++ must have all of the properties C has, plus more. If so, then how does C "rule"? Please excuse my ignorance.

Some OS's don't have C++. Mind you the popular ones do, but I have a few clients that use an OS called THEOS (www.theos-software.com). There's a Basic and a C. Nothing else. I create Reservation Systems for Dumb Terminals on this OS. Although the Theos Server does support ASP, HTML, and CGI.

Most of the stuff you do is from the prompt, but they are comming out with a Desktop.

Thanks for the info guys.

Nothing against VB - but it's for kiddies. :p

[sarcasm]

I guess if a C++ developer is a real man, is an assembly programmer a God? ;)

P.S. - I can read any C++ program, but make me look at VB code and I'm lost. (Never written a single line at all.) I can understand it somewhat, but I couldn't write it. :rolleyes:

U had better not let the VB programmers here remember your name! For all u know, your boss might force you to code something in VB one day, and while u're all panicky and such, u thought that u might be able to get help from the VB forum at Codeguru. But because of your statement, they get angry and refused to help you, and you can only go elsewhere.......and if word gets around that u made this statement, all the VB programmers in this world would boycott you and you can only get prepared to explain to your boss why u didn't finished your VB program! :D

I was something like you in the past, although my C++ isn't even 1/4 as great as ye'. But then, my school introduced VB......and......I had no choice but to humble myself and ask help from the VB programmers, and now, I'm a better and kinder person. :)

A very experienced and expert VB programmer is a Real Man, while a very powerful and great C++ programmer is a Sage.
A legendary and skillful Assembly Language programmer is a Seraphi, whilst a marvellous and powerful Machine Language programmer(pure numbers) is the Lord...........God Himself. The Almighty. :o
Amen.

Alright, alright. I'm getting too extreme here. :D

How VB would accomplish this....

I want to allow a derived class to use a variable from my base class, but not directly, and not expose the method as a public one that any code could call it given the object.

The answer in C++ is to make the member private, and have a protected member function that can be called by the derived class. (Private members of the base are included in a derived class, but they cannot be accessed directly. Only through a protected member function (or public). Friend classes can also use the protected member, but only the base class that has the private member can access it directly. Encapsulation anyone? ;) I take that back, with what I like to call 'hacks', any code can still access it - but not through normal means. reinterpret_cast, etc....)

VB is for kiddies. (Power wise - otherwise, it's not. Don't take me wrong. ;) )

And if they absolutely wanted something VB compatible, I'll write a COM object in C++ and they can call it in VB. I don't need to learn VB. :p (That's all VB.NET,C#, and VC++ 7.0 with the extensions turned on is - not true objects - they're COM objects. Hello super slow Windows of the future. :rolleyes: Not to mention platform compatibility just went out the door for sure - goodbye Windows. )

Wow!!!

I don't know how to accomplish that in VB -- much more in C++ because my knowledge in the latter is very elementary.

And I may not be able to accomplish that forever because I only deal with real problems such as budgets, forecast, sales distribution, sales territory planning, etc. from the smallest brick to the corporate level. That's the beauty of VB. It allows kiddies like me to solve real problems directly. :cool:

I don't know why some of the real men hardly accomplished the same 5 years ago. Probably (sorry, just a guess) because, before they could deal with the real problem, they have, first, to " … make the member private, and have a protected member function that can be called by the derived class. (Private members of the base are included in a derived class, but they cannot be accessed directly. Only through a protected member function (or public). Friend classes can also use the protected member, but only the base class that has the private member can access it directly…." etc, etc.

:D :D :D

... and of course, I would like also to solve highly technical problems someday. So I'm into C++ from time to time. See you in that forum later guys.

Totally true, James! But that's 1 new trick I learnt! I mean, now I knowmore of what the 'protected' keyword is for!
(before this, I very very seldom use 'protected' members of a class at all)
Since u appear high, mighty, skillful and arrogant, I believe you've been programming in C++ for a long time, eh? After all, only the highest of programmers talk in such a manner. :):D

Totally true. Unlike in VB most of the time, in C++, u've to plan much more carefully and worry about lots of bugs and memory issues all the time. In VB, all these stuff are hidden, and it's much less likely to get bugs in a VB program than it is to get in a Visual C++ program.
In VB, it's like swimming in a swimming pool with 600 of the world's most skillful life-guards watching you and preparing to save you should you show any signs of drowning.

In Visual C++, it's like swimming in the Pacific Ocean at night with just a vest and a pair of boxers. It's night, and u can't see clearly. Sharks too. Beware. And oh. In case you get too tired or leg cramps, u're dead. And not to forget, the storm and the waves. Terrible, I say. :rolleyes:

But one great thing about Visual C++ is that if you survived, u'll be well respected in programming parties. That's why! :D:D

Yes I did Xeon pal. That's because don't deal too much on bugs and memory issues. ;) ;) ;)

Aye~! If I had code in VB from the start, I would probably be giving babies to many a **** by now. :D:D:D

You can't do that in VB. But, you can use derived class, but it is not as well as in C++ language. Let's say that C++ encapsulation, derivation, polyphormism and all those class systems are the betters on the market; you cannot do as well in any other language, including java and Delphi...
