I recommend you use the following FREE leak detecting code:
http://code.axter.com/leaktracker.h[^]
You can download the assoicated DLL file via following link:
http://code.axter.com/leaktracker.zip[^]
This program will output the leak location (source-file-name, line-number). It will also give the Function name if your compiler supports it (like VC++7.x & GNU 3.x)

this does not work, first I just added leaktracker.h to the project, lib and dll to windows system dir and run the project from VS 2003. Then closed the project and get standart memory leak in VS output window but there was no file C:\zz_David_Maisonave_DefaultLeakTrackerLogFile.log after termination. Then I added #include to the .cpp file that created additional mem leak on purpose for testing and the project doesnt want to be compiled:

In your sGenDlg.cpp file, the leaktracker.h must be the LAST included header.
If you include it before any other headers, you'll get compile errors, or runtime errors.
This program was originally developed using VS 2003, and then ported to GNU, Borland, and VC++ 6.0.
So it should definitely work on VS 2003.
FYI:
If it doesn't produce a log file, then either it was not compiled in DEBUG moder, or there were no memory leaks.
Since you didn't get compile errors the first time, I must assume it was not compiled in DEBUG mode.
If you don't see the following message when you compile, then the leak tracking code is not getting included.
**************************************************************************************

**************************************************************************************
If you wish to include the leak tracking code in the release version of your program you could do so by defining the following macro before including the header:
#define DEBUG_VERSION_

No I'm not inclined to use it in release version, I'm sure I've got debug compiler option and I included it as you said:
#include "stdafx.h"
#include "sGen.h"
#include "sGenDlg.h"
#include ".\sgendlg.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#endif
#include "Lib\lib.h"
#include "Lib\quantize.h"
#include "LibST\scomplexity.h"
// CsGenDlg dialog
#include "leaktracker.h"
CsGenDlg::CsGenDlg(CWnd* pParent /*=NULL*/)
: CDialog(CsGenDlg::IDD, pParent)
, m_freq(10)
, m_sr(128)
, m_len(30), data(0)
, m_asize(2)
, qt(0)
{
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
}
All the same compiler errors again? it doesnt want to be compiled, I use VS2003.
As for the first time I did not include leaktracker.h in any cpp file at all, which is not proper as I've read from its manual that it should be included at least in one file, and I ran it in debug mode (which we select from proj settings->config manager->active solution config), and to test it I used on purpose allocation of memory with new command without deleting it.
What is your suggestions?
look at the errors again:

I see the problem. This is an over-sight on our part.
In your above code, you have the following:
#ifdef _DEBUG
#define new DEBUG_NEW
#endif
If you include the leaktracker.h file after the above line, that will cause the compile errors.
I've updated the leaktracker.h file so that it does an #undef for new.
#ifdef new
#undef new
#endif //new
You can download the new version, or just add the above 3 lines in the leaktracker.h file around line 177 (right before the new operator).

FYI:
If you're using MFC, also make sure to include the header after macros like IMPLEMENT_DYNCREATE.

In your application, (if it is a MFC application, add the following in the InitInstance())
_CrtSetBreakAlloc(715);
it will break when it tries to allocation the leakage memory and you can find the source code.
Details can be "Memory Leak Detection" in VS.

Hello,
I have the Ascii Code from a character, for example: 101, which is e. How can I convert this int Value into a char or better CString ?
With best regards,

|
|

Sorry but I think I wasn't clear enough. I need the integer(101) represtented as a char(e).
So I need to convert the ASCII code(101) back to the character it represents
|
|
|
|
|
what i understood is that u want to convert the ASCII value into char
char c=char(101);
another way
int i= 101;
char=static_cast<char>(101);
but keep in mind with range of c
never say die

int asc_int;
CString S_temp;
S_temp.Format("%c",asc_int);
thats it

If i have an access database with a table called "USER" with fields ID, AGE, NAME, ADDRESS, and i want address of all users with age = 23, a simple sql query will do (SELECT * FROM USER WHERE blah blah)..
But when I have data in a CSV File, how would i build this sql query? select * from what? 
Any help or pointers in this direction is highly appreciated.

Hi Rajesh,
csv file is nothing, just a comma seperated data and whole line denotes a record.
for executing query AFAIK, you have to import that in access and proceed in similiar way you mentioned above.

Hi Alok,
ThatsAlok wrote: csv file is nothing, just a comma seperated data
Thanks for your reply, but I too know its Comma separated text data. My concern is that it would be faster to use CSV instead of Access database.

Dude, I have exported values from Access and created the CSV because it would be faster. You are asking me to create a MDB out of it again

Rajesh is correct.
1. Create a CSV file by exporting 10000 records.
2. Perform data operation on your MDB and CSV file.
3. You will surely find csv to be faster since it is text based.

|

hi,
Use OpenRowSet for performing data operations on .CSV files. I do not know if you could edit data, but you could query for sure.
