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...

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;

CStringA?

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

...
#ifdef _UNICODE
  wcout << LPCTSTR(str);
#else
  cout << LPCTSTR(str);
#endif

virtual void BeHappy() = 0;

Probably it is a UNICODE issue.
Try changing

printf("%s",str);

with

printf("%S",str);

to check it.

BYTE to binary conversion

24-Mar-10 3:15

CString str;
str="IP conneted"//assigning Multibyte to Unicode variable, i miss a 'c' Roll eyes | :rolleyes:

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

Confused | :confused:

i would write

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

Hi all,

if I have BYTE bTemp = 0xAB;

I need the binary stream of this BYTE value(ie 010101011) in to an integer Array.

Is there any short way to do that rather to write the code to convert it?

Thanks
M Chauhan

use memcpy but be aware of data size types.

Try it

void TranslateBits(CArray<int>* pcArray, BYTE* pbyData, size_t cbDataSize)
{
  if (pcArray && pbyData && cbDataSize) {
    for (int i = 0; i < cbDataSize; i++) {
      BYTE byData = pbyData[i];
      for (int j = 0; j < 8; j++) {
        int iBit = byData & 1;
        byData >> 1;
        pcArray->Add(iBit);
      }
    }
  }
}
 
void Usage()
{
  BYTE byData(0xAB);
  CArray<int> cBitsArray;
  TranslateBits(&cBitsArray, &byData, sizeof(byData));

__declspec(dllexport)ULONG WINAPI FreeMsg(BSTR pMsg)

Good day Friends!

Here comes a new challenge!
Need to discuss whether it is right or what?

My problem is that the challenge sent by the server should be 8 bytes as i read from the documentation. As i decode the hash send by the server and Extract Challenge from it, it gives me only 7 characters including null character.

should i generate the response by using that 7 byte challenge or somewhere i am wrong.

is the challenge must be 8 bytes?

In short my question is:: can a challenge be less than 8 bytes?

The documentation says that authentication is base64 encoded data. It looks like this:

AUTH NTLM <base64encoded type 1 message>	//client
334 <base64encoded type 2 challenge message>	//server... the challenge itself is an 8-byte block of random data
<base64encoded type 3 response>			//client
235 NTLM authentication successful		//server

For details see The NTLM Authentication Protocol[^], at the end is another example for SMTP.

hi,
i have a multibyte application.nw i m setting its tooltip with

_mbstowcsz(pTTTW->szText,buffer, sizeof(pTTTW->szText)/sizeof(pTTTW->szText[0]));

which is showing garbage.any alternative?

Richard MacCutchan23-Mar-10 22:34

23-Mar-10 22:34

Are you sure the tooltips are set to use Unicode? Take a look at the sample code here[^].

I did not provide an example, I pointed you to the MSDN page describing how to achieve what you want to do. Have you coded it exactly as shown? Have you run it through the debugger to ensure your conversion is working correctly?

yes i debugged it PTTW->sztext is setting correctly but when i run it garbage is shown in tooltips..my question is that PTTW->sztext is for unicode apps so wat shud be done if app is multibyte.
