Hi everyone,
I use Visual Studio .NET 2002 right now, and I discovered a bug last night
that I have found few references to on the internet. Basically, if you
allocated a null-terminated char array that is 16 bytes or longer to
std::string, it stores garbage into it:
std::string s = "12345678901234 56";
I tried this on .NET 2003 at work, and this bug has been fixed. Indeed, I
stepped into the string code, and found the difference somewhere in
<xstring>.
Anyway, my question is: what do I do? Do I really have to remove 2002 and
install 2003? Is there an bug-free STL implementation that I can download
somewhere and use instead? I have found no mention of this bug on M$ website
(big surprise).
Thank you for your time,
Tony

It's not a bug. Strings 16 characters or shorter are stored in the
object, while longer strings are stored on the heap. The debugger just
doesn't show the heap-allocated strings by default.

Be seeing you.

What specific code did you use that caused you to come to this
conclusion?
I tried this on .NET 2003 at work, and this bug has been fixed.
I'm not yet convinced you've discovered a bug.

stepped into the string code, and found the difference somewhere in

Difference between what and what?
Anyway, my question is: what do I do?
First confirm that there really is a bug.
Do I really have to remove 2002 and
install 2003? Is there an bug-free STL implementation that I can download
somewhere and use instead? I have found no mention of this bug on M$

I don't see you referring to any particular 'bug.'
What behavior are you getting with what code that
causes you to cry 'bug'?

The bug is in the debugger, which fails to display long strings properly.
(We use the Small String Optimization from V7.0 onward.) The strings
themselves are correct.

When I ordered my new laptop, Sony didn't offer Access 2003 in its bundles.
Recently, I have begun to design Access databases using an copy of Access
2002 from my previous laptop. It works fine, but I would like to have all
the office apps on the same version. So I have a few questions:
1) Is the file format the same as 2002? Can 2002 users read 2003 files?
2) What are the major reasons for upgrading to 2002 ?

Hi,
If we want to compile an Access 2002 database and distribute it to
others, will the compiled software run on any PC, like Windows 98,
Windows 2000, etc.
Also, you don't have to have Access 2002 in order to run it do you?
Thanks!

Hi all
I've taught myself C# 2002 using VS.NET 2002. I've recently brought myself
an ASP.NET 2003 book. I will work through this ASP.NET 2003 using VS.NET
2002 and C# 2002. I don't fully understand the differences between the VS.
NET 2002 and VS.NET 2003.
Will I restrict myself in any way learning ASP.NET 2003 but only using VS.NET
2002 and C# 2002?
