泳池里的故事（泳池小故事动态闪图）

1、打开文件的方式中,有一种是在文件尾,写新的数据-------------------------------MFC的话,你看是不是用这个CFile:modeNoTruncate Combine this value with modeCreate. If the file being created already exists, it is not truncated to 0 length. Furthermore, if the file being created already exists, the underlying file pointer will point to the beginning of the file. This flag guarantees the file to open, either as a newly created file or as an existing file. This might be useful, for example, when opening a settings file that may or may not exist already. This option applies to CStdioFile as well.
