windows注册表操作，包装类，使用方便。-If you are a Windows Programmer or aspiring to be one, it is almost inevitable that at some point or another, you� re going to have to make use of the Windows Registry. When and if you reach this point, you� ll be greeted with some rather unattractive and confusing Win32 registry functions. Using these functions directly often becomes a tedious and irritating experience�　So, to assist in the process of accessing and manipulating the registry, I� ve created a wrapper class which makes the task child s-play, so you can spend more time working on your project and less time fretting about how to make use of the registry. To make use of the CRegistry class within your project, simply employ the preprocessor to include "registry.h".
