此VP的MFC框架是通过创建线程的方式运行的

此框架的优点：

1.使用方便，通过继承一个类的几个函数，就能达到应用vp的目的

类似于vega的zsVegaView类

2.可以使用MFC的键盘响应函数，可以实现多键响应

3.避免使用vpApp向导类

4.可以方便的使用各种vp subscriber类

与MFC结合较紧密-The VP of the MFC framework is a way through the creation of threads running on the merits of this framework: 1. Easy to use, through inheritance of a class of several functions, the application will be able to achieve the purpose of vp of vega-like zsVegaView of 2. Can be used MFC to respond to the keyboard function keys can be achieved in response to more than 3. vpApp guide to avoid the use of Class 4. to facilitate the use of various types of vp subscriber closer integration with MFC
