您好,今天小編胡舒來為大家解答以上的問題。泳池小故事講的是，泳池小故事動(dòng)態(tài)閃圖相信很多小伙伴還不知道,現(xiàn)在讓我們一起來看看吧！

1、打開文件的方式中,有一種是在文件尾,寫新的數(shù)據(jù)-------------------------------MFC的話,你看是不是用這個(gè)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.。
