HI, I am using CFIle in my application and when i compiled my code i am getting error 'WriteHuge' : is not a member of 'CFile'

'ReadHuge' : is not a member of 'CFile'

I included

    #include "afx.h" 
    CFile file;
    file.WriteHuge(m_pDib,bmpFileHeader.bfSize-nBmpFileHeaderSize);
    file.ReadHuge(m_pDib,bmpFileHeader.bfSize-nBm开发者_如何学运维pFileHeaderSize);

Please help
