    Code:
    DPError		dpResult		=  DPMS_SUCCESS;
        FILE		*hFile			= NULL;
    	BOOL		bRetValue		= FALSE;
    	CDPString   dpFilePath;
    	size_t      size            = 0;
    	char       *tBuffer		= new char[m_sFileSize];
    	tBuffer = m_pszStream;
    
    
    	dpFilePath   = m_dpFilePath;
    	dpFilePath   += "\\";
    	dpFilePath   += m_dpFileName;	
        
    	if(hFile == NULL)
    	{
    		hFile = fopen(dpFilePath, "a+");
    		if(hFile)
    		{
    			size = fwrite(m_pszStream, m_sFileSize,sizeof(char), hFile);			
    			if(size < 0)
    			{
    				dpResult = DPMS_FILE_WRITE_ERROR;
    			}
                fclose(hFile);
    		}
    		else
    		{
    		   dpResult = DPMS_FILE_OPEN_ERROR;
    		}		
    	}	
    	
    	return dpResult;
    }
    in this code i had made size of file as member variable but i want it to access through the char* type of buffer. this char* could contain any type of data like binary string so the size should be for binary data also.
