可以很方便的就能够在程序中输出日志等调试信息的类CLogFlieEx（这个是CLogFile的升级版，日志输出可以精确到毫秒级）。使用方法：添加*.cpp，和*.h文件到工程之后，实例化一个CLogFlie对象，之后直接调用AddRecord()函数就可用了。-Can be very convenient to be able to log in the procedure output, such as the type of debugging information CLogFlieEx (This is an upgraded version of CLogFile, log output can be precise to the millisecond level). Usage: add*. cpp, and*. h files to the project after a CLogFlie instantiated object, followed by a direct call AddRecord () function can be used.
