我是今天刚到这里注册的新用户，还望各位高手多多指点！！！
在ＶＢ的运行界面我想注入背景音乐，应该怎么做？　

using System;
using System.Runtime.InteropServices;
namespace Notes
{
/// <summary>
/// Helpers 的摘要说明。
/// 播放声音
/// </summary>
internal class Helpers
{
[Flags]
public enum PlaySoundFlags : int
{
SND_SYNC = 0x0000, /* play synchronously (default) */
SND_ASYNC = 0x0001, /* play asynchronously */
SND_NODEFAULT = 0x0002, /* silence (!default) if sound not found */
SND_MEMORY = 0x0004, /* pszSound points to a memory file */
SND_LOOP = 0x0008, /* loop the sound until next sndPlaySound */
SND_NOSTOP = 0x0010, /* don't stop any currently playing sound */
SND_NOWAIT = 0x00002000, /* don't wait if the driver is busy */
SND_ALIAS = 0x00010000, /* name is a registry alias */
SND_ALIAS_ID = 0x00110000, /* alias is a predefined ID */
SND_FILENAME = 0x00020000, /* name is file name */
SND_RESOURCE = 0x00040004 /* name is resource name or atom */
}

[DllImport("winmm")]

public static extern bool PlaySound( string szSound, IntPtr hMod, PlaySoundFlags flags );

}

}
申明类Helpers,然后调用:
//调用系统函数播放声音
public void Play( string strFileName )
{

Helpers.PlaySound( strFileName, IntPtr.Zero, Helpers.PlaySoundFlags.SND_FILENAME | Helpers.PlaySoundFlags.SND_ASYNC );
}

二楼的同志，多谢了！

人家那是c++

那在VB里面应该怎么写呢？还请各位前辈多多指教！

请问2003怎么实现呀
期待!!!!
