how to create .bin file to save the values for windows mobile

Hi all,
I am working on windows mobile 6.0 and trying to create .bin file to store the data but it is not creating the .bin file.I am using the following code :

Code:

---

      try
        {
                CFile flcall;
                flcall.Open(L"CallLog.bin", CFile::modeCreate|CFile::modeWrite);
                CArchive ar1(&flcall, CArchive::store);
                ar1.Close();
                flcall.Close();

        }
        catch(...)
        {
        }

---

this code works for desktop application.Could you tell me that why it is not creating?


thanks
