[DllImport("winmm.dll")] //引用winmm.dll

public static extern long waveOutSetVolume(long deviceID, long Volume);

在winmm.dll中

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

ProcessStartInfo Info=new ProcessStartInfo();

Info.FileName = "Sndvol32";

Process.Start(Info);

VB和点虐 差别是什么啊

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。

求大神修改 vb点虐 SetWaitableTimer(mlTimer, ft, 0, 0, 0, 0) 导致堆栈不对称 怎么修改?

SetWaitableTimer的声明错了
