我们先来看下下面的代码

//获取文件大小
DWORD Get_File_Size(const char* m_FilePath)
{
    unsigned long size;
    if (_access(m_FilePath, 0) == -1)//文件不存在 2013.09.24
        return 0;
    
    FILE* fp = fopen( m_FilePath, "rb" );
    if(fp==NULL)
        return 0;
    fseek( fp, SEEK_SET, SEEK_END );
    size=ftell(fp);
    fclose(fp);
    return size;
}

BYTE bReadBuf[1024*100];
    DWORD dwFileSize = Get_File_Size("C:\\pub.txt");
    AfxMessageBox(IntToStr(dwFileSize));
    FILE *fp = fopen("C:\\pub.txt","rb");
    if (fp != NULL)
    {
        fread(bReadBuf,dwFileSize,1,fp);
        if (!feof(fp))
            AfxMessageBox("1");
        else
            AfxMessageBox("2");
        int nRe = fread(bReadBuf,1,1,fp);
        AfxMessageBox(IntToStr(nRe));
        if (!feof(fp))
            AfxMessageBox("1");
        else
            AfxMessageBox("2");
        fclose(fp);
    }
