"Hello World\n",
i have the following problem:
One of my headerfiles for a lib is including <vector>.
When i compile the lib, everything is done well.
In my application another file is including <map>.
By linking my application and the lib, following errors occur:
error LNK2005: "public: __thiscall std::basic_string<char,struct
std::char_traits<char>,class std::allocator<char>

Hi All,
I have a *.cer file, a public key of some one and I want to encrypt some
thing using this public key.
Can someone point me to a sample code for Encrypting some file using
X509Certificate ( *.cer file ) so that it can be used to email as
attachment.
The real part is Encrypting using X509Certificate and CryptoServiceProvider.

When trying to compile (using Visual Web Developer 2005 Express Beta;
frameworkv2.0.50215 ) the source code below I get errors (listed below due to
the use of ICallBackEventHandler. Ultimately I want to use a callback from
the client side to update webcontrols based on user input without using
postback.
I am seeking a way to stop the compile errors.

Why can't I use a class destructor in a using declaration:

Many of my C++ programs have the line
using namespace std;
but the "Accelerated C++" book of Koenig and Moo has many examples
where the library names are included one at a time, for example
using std::cin;
using std::cout;

I ran into a problem on HP-UX 11.00 the other day, where it refused to
compile a program using 'using namespace std;' at the top. The reason
seem to be that the compiler refuses to accept 'using namespace std;'
unless the std namespace was declared first.
This triggered my curiosity, and I tried to find out what the ANSI C++
standard had to say about this. I'm unable to find a conclusion, and
hope someone here have a clue to spare.

I've done some extensive searching and can't seem to find an answer to
this -
Is it correct to using "using" with templates, for example:
using std::vector;
Or do I need to specify the type too:
using std::vector<int>;
Both seem to "work" on the compiler I have and I can't find any
documentation saying which is correct, or are both correct?

Hello,
I don't want to dump everything in System namespace into global namespace,
so I fully qualify all names. But it makes things hard to read, for
example, writing System::Xml::Serialization::XmlAttributeAttribute instead
of simply XmlAttributeAttribute. I do this in all my headerfiles. All
examples I read on CSharp (there are none for mc++!) dump everything into
global namespace. What is the recommended way?

I have some .NET 1.1 code that utilizes this technique for encrypting
and decrypting a file.
http://support.microsoft.com/kb/307010
In .NET 2.0 this approach is not fully supported (a .NET 2.0 build
with these methods, will appear to encrypt and decrypt, but the
resulting decrypted file will be corrupted. I tried encrypting a .bmp
file and then decrypting, the resulting decrypted file under .NET 2.0
is garbage, the .NET 1.1 build works...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
