about the NAMESPACE_BEGIN(CryptoPP), i really dont know. the compiler understands that it its the beggining of the namespace and at the end of the file theres a NAMESPACE_END. when i look at the object browser it has something like this:
CRYPTO
{}CryptoPP //meaning that cryptopp is inside crypto
{}Std
about including the header file of the namespace, i dont now which one since every file of the class has that thing inside...
by the way, i cant even include the files of CRYPTO into de files of ZEUS
example:
#include "config.h" //cannot include file, no such file or directory

Well you have to include every header file that defines any class that you want to use anyway. If you are really this confused about header files and namespaces you might need to learn a little more about C++ fundamentals before attempting your project.

that would be perfect but try explaining that to my dad.
lets try this example:
file structure:
CRYPTO
-config.h
ZEUS08
-myfile.cpp
config.h
NAMESPACE_BEGIN(CryptoPP)<br />
<br />
typedef unsigned short word16;<br />
typedef unsigned int word32;<br />
<br />
#if defined(__GNUC__) || defined(__MWERKS__) || defined(__SUNPRO_CC)<br />
#define WORD64_AVAILABLE<br />
typedef unsigned long long word64;<br />
#define W64LIT(x) x##LL<br />
#elif defined(_MSC_VER) || defined(__BORLANDC__)<br />
#define WORD64_AVAILABLE<br />
typedef unsigned __int64 word64;<br />
#define W64LIT(x) x##ui64<br />
#endif
since it has the definition for W64LIT i decided to include it.
so i put into my file
#include "config.h"
but it gives me fatal error C1083: Cannot open include file: 'config.h': no such file or directory
would u please help me with that or give me a link to c++ basics¿?

Looks like a n include path problem, not a namespace problem.
I'm still curious what the NAMESPACE_BEGIN macro expands to...

include path problem, im gonna research about that.
about the namespace begin im gonna post few of the files for you to see at least how its supposed to work. wei dai wrote it somehow and it works, i just need to use that library in order to use cryptography in my solution.

That's absolutely necessary, since any other problems will be un-fixable until you can successfully include the header files you need.

by the way, do you have any interesting link about including? cant find anything useful yet...

yay! thenks Mark, that was the answer i was looking for, ill code it later since i have to go out. take care everyone

Give him the keyboard and I will. Is he the one telling you that you don't need to learn how to do C++ development to do C++ development? Who ever is telling you that is wrong. If you try to Internet Forum your way through this project it's going to take you like 1000 times longer than it would if you just stopped and learned C++ fundamentals first and then did the project. Also after you are done you will have learned about a 1 tenth of what you would had you spent the time actually focusing on learning fundamentals rather than focusing on getting the project done.

what the heck is that?
Some compilers introduced namespaces pretty recently (gcc, for instance), and some libraries are using such macros to take this into account. Xerces-C is doing something similar.

hi, i am creating a ftp program using winInet in win32... in non asynchronous mode(no callback). it is connecting and when i use the ftpgetcurrentdirectory then return value whether true or false is immediate but actually the operation takes some time... how to detect whether the function has ended or not...? i dont want to use callbacks for this... but what i did was i used a timer to check the buffer whether the function returned any string... i feel this aint a proper way... and when i used the asynchronous mode i used a callback function in that there are many defined constants for which the compiler says undefined symbol... i am using dev-c++ IDE bu including the needed library in my project...
the call back function is called for opening and connecting to the server but not when i use the ftp_ functions... i am toggling between various methods to acheive some positive result but there wasnt a favorable result... phew and then i tried to use sockets like i used it for my own http request to my server... what will be the better way to use sockets to connect to the ftp server??? oh this line is the actual purpose of this big explanation... so this is my problem... so i am calling this command : CTRL + A and F1 ...

I don't know what that means. If you make a blocking call it is complete when it returns, period.

How did you do that on a blocking call? That shouldn't work at all.
Jach Mullan wrote: i feel this aint a proper way...
I agree.
Have you seen this: FTP Sessions (WinINet)[^]
Looks like sample code for many common FTP tasks using WinINet.

Dear all,
Please give me some clues to construct a screen which can display the points of x, y and z axis in 3d, point by point, by inputing 3 txt files, which each of these txt files contains the value of points in a particular axis, by c++.
If C++ cannot make it, can other program like java achieve this task??
Thank you,
John

Bad news: You've not got one problem, but many different ones.
Good news: None of those are amazingly tough, so you can pick them off one by one.
1/ Read the spec for the files? Can you trust them to have the same number of coords in each?
2/ How will the user tell you what those files are?
3/ Read in the files one line at a time, build a 3d point, and add it to an array
(CStdioFile/ReadString is good for this.)
4/ As your monitor is 2d, go on codeproject and look at some directx / opengl demo applications, and modify them to plot your shiny new points.
You may end up posting help questions for some of these, but at least you'll be doing bite size problems!
Iain.

Depends what you want to achieve exactly. Do you want just a 3D chart (like something you can find in excell) ? If that's the case, just search on codeproject, there are some 3D charts.
If that's not what you want, then you should elaborate your request.
But anyway, a lot of things are possible (probably by using DirectX or OpenGL), the problem is the amount of time you are willing to spend on that.

Thank you for the replies form you guys.
Let me elaborate my request.
I wanna display a line which is constructed and connected by the first point to the last point which resembles animation. The most important thing is to show how the line is connected by points and the graph which shows x,y,z axis clearly.
In addition, the x, y, z coordinates of various points are stored in three txt files where each of the txt file contains the coordinates of one axis only.
Thank you very much!

Hi guys.
I'm new to MFC. I'm doing an SDI app with a ListBox on one pane. There are three panes on the app. I can't change the font style of the listbox control. Any idea on how to do that?
Regards,

I have tried these three methods so far...
// First way
CFont Font;
Font.CreateFont(12, // Height
0, // Width
0, // Escapement
0, // Orientation
FW_BOLD, // Weight
FALSE, // Italic
TRUE, // Underline
0, // StrikeOut
ANSI_CHARSET, // CharSet
OUT_DEFAULT_PRECIS, // OutPrecision
CLIP_DEFAULT_PRECIS, // ClipPrecision
DEFAULT_QUALITY, // Quality
DEFAULT_PITCH | FF_SWISS, // PitchAndFamily
"Arial")); // Facename
pListBox->SetFont(&Font);
// Second way
CFont Font;
LOGFONT lfLogFont;
memset(&lfLogFont, 0, sizeof(lfLogFont));
lfLogFont.lfHeight = 12; // 12-pixel-height
lfLogFont.lfWeight = FW_BOLD; // Bold
lfLogFont.lfUnderline = TRUE; // Underlined
strcpy(lfLogFont.lfFaceName, "Arial"); // Arial
Font.CreateFontIndirect(&lfLogFont);
pListBox->SetFont(&Font);
// Third way
CFont Font;
LOGFONT lfLogFont;
memset(&lfLogFont, 0, sizeof(lfLogFont));
lfLogFont.lfHeight = 120; // 12-pixel-height
lfLogFont.lfWeight = FW_BOLD; // Bold
lfLogFont.lfUnderline = TRUE; // Underlined
strcpy(lfLogFont.lfFaceName, "Arial"); // Arial
Font.CreatePointFontIndirect(&lfLogFont);
pListBox->SetFont(&Font);
