Fixed-length vs variable-length UNICODE, the first that comes in my mind:

UTF-8 is pretty much everywhere and the most used variable-length UNICODE encoding ("multibyte"). Alone for compatibility in network applications or together with XML it could be a very good idea to choose it, probably because it is a "fits-all" format. It is able to represent any UNICODE character, yet backwards compatible with ASCII (7 bit). Also see UTF-8 advantages and disadvantages[^].

That is incorrect MBCS and Unicode are different things. See http://msdn.microsoft.com/en-us/library/5z097dxa.aspx. VC++ implements MSCS as DBCS (Double Byte Character Sets).

P.S. Some how auto links are not working.

to use with MBCS sequences, and it (MBCS) is not fully supported in MFC... Smile | :)

how to create document for .c files which consists of only code in it and does not have any comments included in it.when i am trying to create document using doxygen for the .c files of linphone 3.2.1 then i am getting a warning i.e.
compound _linconfig does have any document...and so on for many .c files...help needed urgently..

It can generate an on-line documentation browser (in HTML) and/or an off-line reference manual (in $\mbox{\LaTeX}$) from a set of documented source files.
where in my case the .c files are just with code not even a single comment i.e not at all documented..k??/
now which software will help me out...to know the functions defined in that particular .c file and what all are the called functions, calling functions...what are the input parameters with output parameters.....now reply

The link I gave you is to the doxygen system, try reading the documentation to find out what you can and cannot do with it.

As has been said, this is kinda rude.

But trying to answer your question... Doxygne is not psychic, it is just a tool to extract formatted comments from your code. If those comments don't exist, then you're just going to have to write them!

This is not as bad as it sounds - I had to do the same from scratch to a project, and I found lots of code that could be refactored as I went. I reduced the code size by a good 5%. That means 5% less bugs!

CString Object in a console application...

rrthangavel24-Mar-10 0:04

Hi,
i am working in console application in VC++(visual studio 2005).
i am having a problem while using CString.
i have mentioned sample code below.

#include "stdafx.h"
#include "server1.h"

#ifdef _DEBUG
#define new DEBUG_NEW
#endif

// The one and only application object

CWinApp theApp;

using namespace std;

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
int nRetCode = 0;

// initialize MFC and print and error on failure
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
_tprintf(_T("Fatal Error: MFC initialization failed\n"));
nRetCode = 1;
}
else
{
CString str;
str="IP conneted"
printf("%s",str);
cout<<str;
}

return nRetCode;
}

while executing the code..
i get printed only first letter(I) of str.
so please help me..
is there any header or setting should i change in the visual studio environment?

Check if the following works:

CStringA str;<br />
str = "IP conneted";<br />
printf("%s", str);<br />
cout<< str;

Yes, for UNICODE settings CString get replaced to CStringW and for Multi-Byte it gets replaced to CStringA. You can check atlstr.h header.

Try it

  wcout << LPCTSTR(str);
#else
  cout << LPCTSTR(str);
#endif

Probably it is a UNICODE issue.

CString str;

printf("%s",str);//non-sense RTFM
cout<<str; // sending Unicode to Multibyte console

Confused | :confused:

i would write

wcout<<TEXT("IP connected") Blush | :O
