    Try it :) :

    {
    ...
    CFile cFile;
    if (cFile.Open(strFileName, CFile::modeRead)) {
    BYTE byBuffer[1024] = {0};
    UINT uiReadBytes = cFile.Read(byBuffer, sizeof(byBuffer));
    CString cszMessage;
    cszMessage.Format(_T("File: %s:\r\nCount of read bytes = %u"),
    strFileName, uiReadBytes);
    AfxMessageBox(cszMessage);
    cFile.Close();
    }
    ...
    }

    virtual void BeHappy() = 0;

            Good, the file can be read in the both cases :) What is your next step (wish) please ? :) Would you like to read and write an UNICODE or ANSI csv-file ? :)

                When your project is configured as UNICODE project the output will be performed by two bytes per character... Would you like to see your output in ANSI ? :)

                    :) چرا که نه؟ Just convert your string to ANSI sequence:

                    #include <AtlConv.h>
                    ...
                    {
                    ...
                    USES_CONVERSION;
                    LPSTR lpszANSI = T2A(cszOut);
                    cOutFile.Write(lpszANSI, strlen(lpszANSI));
                    ...
                    }

                    virtual void BeHappy() = 0;

                        You are welcome ! (sometimes I do read and write UNICODE csv-files, you could it too, when it will be needed once :) )
