VC6.0写的一个小玩意，新公司的入职练手任务。unicode编译环境。要求如下：

题目：用VC6.0实现对unicode格式的文本文件高效率按行读取

要求：

（1）实现以下接口

BOOL OpenStringFile(CString path)

BOOL ReadStringFile(&CString str) //一次读取文件中的一行

BOOL CloseStringFile()

（2）使用内存缓存技术，对于大文件要能达到几十MB/S的速度。

（3）测试程序能实现按行读取后保存在另一个文件(utf-8编码)中。同时能输出读取的速度。



为了节约空间，我把unicode的编译支持库删掉了，大家自行下载，如果VC环境完全安装的，应该可以直接编译。

另外，这个里面，有个公司的公共库，写日志的主要用来。不方便发，我也删了，编译通不过，请大家自行删除这个库相关的设置及代码引用，不影响程序流程。liang20140314-VC6.0 write a gadget, the new company recruits practice hand tasks. unicode build environment. Requirements are as follows: Title: VC6.0 achieve with unicode text file format read by rows of high efficiency requirements: (1) implement the following interfaces BOOL OpenStringFile (CString path)　BOOL ReadStringFile (&　CString str) // read the file once The line BOOL CloseStringFile ()　(2) using memory cache for large files to be able to reach speeds of tens of MB/S' s. (3) The test procedure can be achieved by the line read is saved in another file (utf-8 encoding) in. Output speed can be read simultaneously. To save space, I put unicode compiler support library deleted, everyone to download, if VC environment is installed, it should be compiled directly. Further, the inside, there' s public libraries, is mainly used to write the log. Convenient hair, I have deleted, compiler pass, please delete the library itself and code references related settings, does not affect the prog
