I am working with MSVC6 on Windows XP.
I have created an MSVC project called SHIP
I have a file SHIP.i with "%module SHIP" as the first line (file is below).
I run SHIP.i through SWIG 1.3.24 to obtain SHIP_wrap.cpp and SHIP.py; the
latter contains the line "import _SHIP".
I compile SHIP_wrap.cpp and a bunch of files into a DLL which I have the

So this tells the compiler That if its defined do not define it again.
Could someone help me understand this.

Hi There!
I'm trying to define constants so that I can refer those constants from any
page of my ASP.NET website. I know I can use <appSettings> in web.config XML
file but I don't want to parse and read the whole XML document everytime a
page is requested.
In classic ASP, I used Include files and define constants using Const
keyword so that every page that has been included the file can refer the
constants.

If I have many hard coded values such as file paths, file names, timeouts,
etc, where is the best place to define them? Meaning, in the case something
needs changing for example, rather than running down all the subs or
functions that may contain these values, I'd like one place to change them
and have that changed reflected in the subs or functions that use those
values. I'd like to avoid globals; keeping the values private to only those...

Hi everyone, I have a simple question. I'm trying to make a macro in
one file so I can use it in main.cpp. The idea is that I the user of
my code has simple to type the macro definition to replace a more
complicated code. Something like the following:
// file.h
#define OBJECTIVE template <class T\
void operator()(T& chrom_,double* fitness_);
// file main.cpp

Hello world, I'm wondering if it's possible to implement some sort of
class/object that can perform mapping from class types to strings?
I will know the class type at compile time, like so:
const char *s = string_mapper<thetype>();
However I do not know the string to be associated with the type at
compile time, and will need a way to set up the mapping, to be created
at run time, possibly like so:
void foo(char*...

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:

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
