VC++读写大文件资料（二进制），VC6编译通过，平时我们用词本打开大量文本的时候，会发觉电脑很慢甚至死机，不是因为文件太大，而是因为记事本的简单而未进行大文件打开处理，才会出现这种情况，希望这个VC小实例能启发你一些灵感。 -VC++ to read and write large file data (binary), VC6 compiler, usually we have to open a lot of words when the text will find that the

该源代码详细的描述如何利用内存映射机制来提高文件的访问读写速度，该方法尤其在读取大数据量的文件时候有显著的作用。我们经常遇到读取的数据文件达到100M以上时，用传统的方法进行读取往往会死机，程序效率很低，该方法为解决此类问题提供了一个很有意义的方法。-The source code for a detailed descr iption of how to use memory-mapped mechanism to improve file access to read and write s
