I have used VC7 a lot on my old computer, a PIII-600 with 512 MB Ram, and it worked great. Didn't have to wait much for those dialogs.
A lot of it have to do with your disks though...

First of all, I've only spent aprox. $350 on a VS.NET upgrade.
I also have a great almost new computer (Dual 1800+), but we were talking about the speed on low/middle range computers...

Ellery,
Some of the people replying to this discussion thread are not professional programmers. Rather, they are students learning how to use the latest and greatest tools. Unfortunately, this means that they never paid for VS.NET. I'm sure you can draw your own conclusions from that statement...
From this point of view, they are paying exactly the same amount for the hardware as the software.

I suspect some of them may have bought on a "promotion" and paid only $2 each CD.
Concussus surgo.

I would think a laptop with a 1GHz Duron (256MB RAM) counts as a "decent computer"...and VS.NET runs like a fly in treacle on it.
IMHO There's no denying that VS.NET requires a lot more power than VS6...though even VS6 is pretty slow on large projects.

And if you change the DWORD to a WORD, do you diligently search and replace all references to the variable name with the corrected name? Maybe you do, but I bet a lot of other people don't. Plus, why code the storage method as part of the name? Isn't this why we have getter/setter methods, so we don't need to concern ourselves with internal implementation, and therefore don't care about the storage mechanism?

Actually, I do that, and have no problem with it. If I'm changing the size of something, it's not a bad idea to go look at all usages of it as part of the change; it usually only takes a few minutes. Might as well change them whild looking.

As nice as that sounds, frequently we do care about the storage mechanism. For example, in communicating with external devices - whether they be musical instruments as in my work, or files, whatever - the size of storage is frequently hard-coded and must be respected. Sometimes data must be passed through a pipe of fixed size.. in which case data may be truncated and precision or sign lost.
Here's another example: I work in a typical mixed environment, with character strings represent in various APIs as either char*, CString, or STL string. Frequently I have to deal with two or even all three types in the same chunk of code, all referring to the same text. In this case specific prefixes are very helpful.

In Pavel's defense, I too prepend variable names with their type. I find it generally helps the readability of the code. And yes - if I change a variable type, I do change the variable name accordingly - otherwise doing it in the first place is useless!!
You talk about having get/set functions for data hiding, but what about within the class itself?
I think after using it for a while you can really benefit. My colleague recently named some variables sBlah (CString) instead of saBlah (CStringArray) and it caused no end of confusion!

I use a strongly C++, object oriented notation with a data hiding and others cool stuff, inside the class too.

Yes you should. And it is easy to do. Simply change the declaration and the compiler will not compile until you have made all the neccessary changes. This is about as close to forced self documenting code as it gets. Comments in context are far less easier to find and change.
Marc Clifton wrote:

OK, so you see the following line of code, what does it mean?
bone = currentBone;
Is bone a string or a number or a class? So now you have to look at it's declaration. OK, so now you say, "Well, I wouldn't have named it bone or currentBone."(Hey, neither would I.)"I would have named it boneIndex or boneName." OK, so is boneIndex an iterator or a number or a key in map template? As for boneName, is it const char * or string? All this information is very important in debugging.
Marc Clifton wrote:

This helps for setting/getting members of a class, but what if you are just dealing with variables within code.
Also, remember cast conversion operators are inheirent in even basic types so...
const char * currentBone = "leg";
int bone = 0;
bone = currentBone;
This compiles, but it would far less likely to be written if it was:
const char * pszCurrentBone = "leg";
int nBone = 0;
nBone = pszCurrentBone;

I also make every effort to make my code as neat as possible. But at the end of the development cycle I always end up wondering who the heck wrote that pile of crap while I wasn't looking. I think that there is some kind of thermodynamic principle governing how this happens. It certainly isn't my fault!

You are quite right
I have learned in my software engineering lectures, that there is some "rising entropy" in every software project. Big and long-living projects' code size increases about 10-20% per year - just because of maintaince entropy.

You should have seen me agonising over every line before I submitted that CP+ thing. While I was writing it I was thinking "this rocks", but once it was ready to be submitted I checked over my code and though "god, they are going to have a good laugh at this." 
And I kept looking for the Format Code button for C++ in VS.NET. No such luck... lol.

I can't see how anybody would go for an option other than this. All code must go through a development/debug/maintenance cycle.
So go for anything else would be professional suicide, but thats just my opinion.
Sure, depending on peformance you *may* have to compromise*, but with the speed of todays and future computers, this should be less of an issue as time goes by.

I have never seen a situation that has suffered reduced performance due to formatting concerns. And, I honestly believe that anyone who greatly reduces the performance of code (note that certain temporaries are usually optimized out) by doing formatting changes likely is someone that is not qualified to make those changes!
Peace!

If there are different people involved in one project it seems to me that much better to have the code well-formatted and use Hungarian notation than headache translating it to understand, imagine everyone in the street began to drive just the way he likes
#define __ARMEN_H__
|
|
|
|
|
I agree with the formatting (but NOT with the Hungarian Notation idea!!!  ). However, I've seen this go way over the edge, too, with "style guides" that mandate a particular number of spaces to indent, that all constants (even 0 and 1) must be #define'd (even when 0 and 1 would make more sense), or other things so piddly and against the development environment that it becomes more work to maintain the formatting vs. maintaining the code.
(Regarding my anti-Hungarian Notation thing, in my 20+ years of experience, I've rarely needed to know at a particular spot what type a variable is supposed to be, but I've often needed to know what the purpose for a variable is. Sorry, but lpszText doesn't tell me beans. What's the text supposed to contain?  Besides, it can be a maintenance nightmare when you discover that you need to change the datatype for whatever reason (e.g., it comes from an external source, and it changes from an int to a float).)
