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.

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

Now write it to the table

	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);

Please quote the errors. Try to get the values using GetWindowText. I have already tested the code above that i provided you in this thread earlier.

First of all jDate should not be a string . It should be a control variable for the date time control. Create it using the class wizard and don't take it as a value take it as a control

Have a look at my previous post carefully. You will find that the variable m_datetime should be a control variable and not a string type variable and then use the code provided in the previous post
