Greetings:

I am writing an MFC app with VS 2003. I am trying to track a memory leak. I have replaced all of my "new" keywords with "DEBUG_NEW" as per the Microsoft documentation on tracking MFC memory leaks.

All of my files contain the:

#ifdef _DEBUG
#define new DEBUG_NEW
#endif

lines at the top and I am building in _DEBUG mode.

The compiler is issuing "identifier not found" for all instances of "DEBUG_NEW".

Does anybody know what the problem is?
Thanks in advance,
Mark

Are you using precompiled headers??
if not then try including "Afx.h" file which contains the definition related to DEBUG_NEW macro.

Hi, thanks for your response.

Yes, I am using pre-compiled headers and I also added the include of "afx.h" to the top of all of my files, just for good measure. I am still getting the same result...

Bizarre...

I think you only need to add the definition for new, but you do not have to replace any appearance of your new operators with DEBUG_NEW.

You know, I think you're right. I misunderstood the documentation.

So that means that the memory dump data that I am getting in my output window is as good as it gets? Its not very helpful...

Oh, well...

Thanks for your help.

What are you trying to do ? Could you be more specific ?
If you want to 'open the file in binary mode', you can simply add the flag "b" when calling fopen. But I doubt this is what you are looking for.

Yes but what is adress ? It should be a char array that contains the path to the file.
But you didn't answer my question: what are you trying to do exactly ? I think binary mode is not what you think it is.

Try

FILE * file = fopen(file_name, "rb");

The key issue is the "b" flag.

    CString m_cdate;<br />
    SYSTEMTIME sysTime;<br />
GetSystemTime (&sysTime);<br />
    // Correction here<br />
    m_cdate.Format("%04d-%02d-%02d", sysTime.wYear, sysTime.wMonth,                sysTime.wDay);

Now write it to the table

Use this code //

<br />
	SYSTEMTIME sysTime;<br />
	GetSystemTime(&sysTime);<br />
	CString s;<br />
	s.Format("%04d/%02d/%02d",sysTime.wYear ,sysTime.wMonth,sysTime.wDay);<br />
	AfxMessageBox (s);<br />
<br />

Does this work ........

I tried and tested the code on my machine and it runs well producing the desired output.
Any ways you can try using CTime as Laxman suggested or use COleDateTime

When you are retreiving those dates from the table they would be in string format as I guess. So you just have to format the strings using the
CString::Format() , to get the date in the desired manner and display it then . Post some code so that the problem can be traced out

As i use date time picker in vc++ form so now set a date on it and i want that this date is stored in mysql table but always it store current date.
i uses the code as u tel me code is:

SYSTEMTIME sysTime;
GetSystemTime(&sysTime);
CString s;
s.Format("%04d/%02d/%02d",sysTime.wYear ,sysTime.wMonth,sysTime.wDay);

now i want to srore other than systemdate in mysql table that is to store "1999-09-03" but when i set this date on date time flicker it will store today date as 2006-06-07

I think that you are having a problem in the way you are thinking and asking.
Soln:
m_datetime is the datetime control.
Now when the user modifies the date in the control you can use the following code to get the date that the user had selected in the control

    m_datetime .UpdateData();
char *str=new char[100];
m_datetime.GetWindowText (str,10);
    AfxMessageBox(str);

// str has the date.
//Extract the date from str and now continue.
Now are you able to get the soluction or some other problem

sur my problem is i enter date in date time picker and code read this value through the :
GetDlgItemText(IDC_DATE,jdate)
where IDC_DATE is id of date time picker and jdate store this value
and i declare this jdate as CString.

now i want that value from GetDlgItemText(IDC_DATE,jdate) is stored into mysql table which i specify
i try this code what as i tel u i use jdate instead of m_datetime then it give errors
m_datetime .UpdateData();
char *str=new char[100];
m_datetime.GetWindowText (str,10);
AfxMessageBox(str);
