Retrieve Record number ( ODBC Api) [modified]

On Windows, all the thread creation methods eventually call ::CreateThread()
to create the thread.

The difference is, AfxBeginThread() does MFC-specific initialization on the thread.

The typical rule of thumb is:

Use AfxBeginThread() to create a thread in MFC if the thread will use any MFC objects.
Use _beginthreadex() to create a thread if no MFC objects are used but CRT functions are used (including new/delete!).
Use ::CreateThread() if just Win32 APIs/objects are used.

Also make sure you link to the multithread MFC/CRT libraries!! Smile | :)

You could use the COleDateTime class.

Subtract one ColeDateTime object from another ColeDateTime object and you'll get
a COleDateTimeSpan object, with which you can use its GetTotalDays() method.

did you used in any variable arg functions like wsprintf with format specifier %d, if so you typecast it to int before hand. say, (int)timeDiff.GetTotalDays().

[Added]

    COleDateTime timeDOB( 1983, 9, 2, 0, 0, 0);
COleDateTime timeToday( 2008, 5, 12, 0, 0, 0);
COleDateTimeSpan timeDiff = timeToday - timeDOB;
TCHAR szBuf[256];
_stprintf(szBuf, _T("No. of Days :%d"), (int)timeDiff.GetTotalDays());

<code>
COleDateTimeSpan daydiff=(COleDateTime m_date1-COleDateTime m_date2);
int noofday=(int)daydiff.GetTotalDays();
noofday++;
CString nday,m_no_ofday;
nday.Format("%d",noofday);
//m_no_ofday CString type variable of Edit Box.
//nday gives calculated no of days.
m_no_ofday.SetString(nday);

By that I'm assuming you mean m_no_ofday is a CString attached to the edit
control through the MFC DDX system....

If that's the case, you could just convert the int to that string and call UpdateData()
to move the string contents to the edit control:

COleDateTimeSpan daydiff=(COleDateTime m_date1-COleDateTime m_date2);
int noofday=(int)daydiff.GetTotalDays();
noofday++;
m_no_ofday.Format("%d",noofday);
UpdateData(FALSE);

I think it would be more useful if you post your not-working code.

You can use of CFont::Create and use of SetFont for your work and you need to copy your file to Windows/Fonts and use of Install New Font.
