用VB编写DirectX7.0游戏 　　DirectX7.0终于出现了，同前面DirectX6相同，版本7也带了一个庞大（129M）的SDK开发库，同DirectX6 SDK库相比，DirectX7的SDK库提供了以下新的功能： 　　＊ 对于Visual Basic的支持。用户可以使用类库在Visual Basic环境下开发基于DirectX的程序。 　　＊ 提供更多DirectX3D立即模式（Immediate Mode）下的API函数，以支持DirectX7中新的3D特效，包括立体环境映射、顶点混合等。 　　＊ DirectMusic支持DownLoadable Sound Level 2标准。 　　＊ DirectInput支持8按键的游戏杆设备，同时支持Microsoft的力反馈摇杆。SDK库提供了读取力反馈效果文件的方法。同时提供了Force Editor程序来建立效果。 　　对于VB爱好者来说，新的SDK库终于提供了完整的对VB的支持，现在终于可以使用Visual Basic来编写DirectX的程序了。 (err)
