说明：  这是一个用MCI String Interface编写的一个小播放器。有实用价值，可以用来播放.AVI .MPG, .ASF ..WMV文件。但整个程序作为编程参考更好些。程序提供了一个较完整的窗口框架，例如菜单处理，Rebar和Toolbar控制。程序还解决了几个编写Windows程序经常遇到的小问题：怎样把"Opend"对话框放到父窗口的中间？怎样实现全屏窗口？怎样让窗口总在最前面？
(This is a String Interface with MCI prepared by a small player. Have practical value, can be used to broadcast. AVI. MPG,. ASF WMV .. documents. But the whole process as a programming reference better. The procedures provide a more comprehensive framework for a window, for example, the menu, Rebar and Toolbar control. Procedures also resolved to prepare a few Windows programs frequently encountered problems : how to "Opend" dialog window father put in the middle? How to achieve the full-screen window?
