第一个参数可以为0，表示首选设备
第二个参数为音量:0xFFFF为最大，0x0000为最小，其中高位（前两位）表示右声道音量，低位（后两位）表示左 声道音量 。
2、弹出系统音量调节框

第一，VB什么时候都不是世界上使用人数最多的语言。其次，我真的不知道VB这东西有什么好的，如果说VB给当初困扰中的windows程序员们提供了一个所见即所得的UI开发环境，那么其实他们真的应该多关注Delphi、C++
Builder。第三，.NET跟微软的web
service也没有一毛钱的关系，微软第一个web
service的标准是SOAP，2000年左右出的。VB.NET与其说是VB，不如说是微软为了挽留VB程序员做的努力。拿VB去比C++更是令人发指。第四，.NET并非一个编程语言，C#、VB.NET、托管VC、Delphi
.NET都是.NET家族的。
