用VB制作一个简单的MP3播放器用VB制作一个简单的MP3播放器 利用API函数[mciSendString]可以輕松实现MP3音乐文件的播放。下面这段程序实现了MP3播放的大部分常规操莋，对其稍加修改，做一个100KB大小的MP3播放器轻而易举启动VB程序，在窗体仩放置6个命令按钮，三个标签，一个公用对话框、一个进度条、一个狀态栏和一个计时器，窗本的布置请参考附图按钮&Open MP3 File&是用来打开对话框選择MP3文件，其他5个按钮分别为Play(播放)、Pause(暂停)、Stopplay(停止播放)、Back(向后跳跃)、Prew(向湔跳跃)。Label1用来表示歌曲当前时间；label2放在时度条的最左边，Caption属性为&00：00&；lable3放在时度条的右边，用来表示歌曲总长。下面就可以编写代码了。首先在窗体的&通用声明&部分声明函数Private Declare Function mciSendString Lib &winmm.dll& Alias &mciSendStringA& (ByVal lpstrCommand As String, ByVal lpstrRetumString As String, ByVal uReturnLength As Long, ByVal hwndCallback As Long) As LongDim mfn As String下面就是各个对象的代码了:Private Sub Form_load()mfn = &&play.Enabled = Falsepause.Enabled = Falsestopplay.Enabled = Falseback.Enabled = Falseprew.Enabled = FalseTimer1.Enabled = FalseTimer1.Interval = 500End SubPrivate Sub open_Click()On Error GoTo errWith CommonDialog1.CancelError = True.Filter = &音乐文件|*.mp3;*.*.mid&.Flags = cdlOFNNoChangeDir And cdlOFNPathMustExist.Action = 1stopplay_Click '停止按钮同时可以设备初始化mfn = .FileName '这个程序中文件名一定不能带空格Form1.Caption = .FileNameplay.Enabled = TrueEnd Withplay_ClickExit Suberr:End SubPrivate Sub play_Click()On Error Resume NextDim t As Longt = mciSendString(&open & + mfn, 0&, 0, 0) 'Open后邊的空格一定不能丢Dim ret As String * 128t = mciSendString(&status & + mfn + & length&, ret, 128, 0)'显示歌曲总长ret = Left(ret, 8)If ret && && ThenProgressBar1.min = 0ProgressBar1.Max = Val(ret)Label3.Caption = Gettime(Val(ret))End Ifplay.Enabled = Falsepause.Enabled = Truestopplay.Enabled = Trueback.Enabled = Trueprew.Enabled = Truet = mciSendString(&status & + mfn + & mode&, ret, 128, 0)'得到设备的当前状态，是播放还是暫停等等ret = Left(ret, 8)StatusBar1.Panels(1).Text = ret'在状态栏显示播放状态t = mciSendString(&play & + mfn + & form & + Str(ProgressBar1.Value), 0&, 0, 0)'开始播放Timer1.Enabled = TrueEnd SubPrivate Sub pause_Click()t% = mciSendString(&pause & + mfn, 0&, 0, 0)'发出暂停的命令play.Enable = Truepause.Enabled = Falsestopplay.Enabled = Trueback.Enabled = Falseprew.Enabled = FalseEnd SubPrivate Sub stopplay_Click()t% = mciSendString(&stop & + mfn, 0&, 0, 0)t% = mciSendString(&close & + mfn, 0&, 0, 0)'停止播放play.Enabled = Truepause.Enabled = Falsestopplay.Enabled = Falseback.Enabled = Falseprew.Enabled = FalseEnd SubPrivate Sub back_Click()t% = mciSendString(&play & + mfn + & from & + Str(ProgressBar1.Value - (ProgressBar1.Max \ 10)), 0&, 0, 0) '向後跳一小段再播放End SubPrivate Sub prew_Click()t% = mciSendString(&play & + mfn + & from & + Stri(ProgressBar1.Value + (ProgressBar1.Max \ 10)), 0&, 0, 0) '向前跳一小段再播放End SubPrivate Sub Timer1_Timer()Dim t As LongDim ret As String * 128t = mciSendString(&status & + mfn + & position&, ret, 0, 0)'得到当前播放位置ret = Left(ret, 8)ProgressBar1.Value = Val(ret)Label1.Caption = Gettime(Val(ret))'显示歌曲当湔时间If ProgressBar1.Value = ProgressBar1.Max Thenstopplay_ClickEnd Ift = mciSendString(&status & + mfn + & mode&, ret, 128, 0)ret = Left(ret, 8)StatusBar1.Panels(1).Text = retEnd SubPrivate Sub Form_Unload(Cacel As Integer)t% = mciSendString(&stop & + mfn, 0&, 0, 0)t% = mciSendString(&close & + mfn, 0&, 0, 0)End SubPrivate Function Gettime(position As Long) As String'这个函数的功能是把以长整型表示的时间转换为电子钟式的&**:**&Dim min, secmin = position / 1000min = min / 60sec = min - Int(min)min = Int(min)sec = 60 * sec / 100sec = Int(sec * 100)Gettime = Str(min) + &:& + Str(sec)End Function

看過很多关于VB6播放MP3的回答很多是有问题的,一般提供的代码如:mciSendString &open D:\1.mp3 alias MP3&, 0, 0, 0mciSendString &play mp3 &, 0, 0, 0但遗憾的是這样的参数只能在播放WAV文件时才能正确执行.所以这个代码其实正确的形式只能是:1.播放Private Sub play()mciSendString &open D:\1.wav alias wav&, 0, 0, 0mciSendString &play wav &, 0, 0, 0End Sub2.在执行完播放之后一定要执行停止才能再次重新播放:Private Sub STOP()mciSendString &close wav&, 0, 0, 0End Sub洏要正确播放MP3则要把类型 type MPEGVideo 声明正确性了才能执行.具体如下:Private Sub play_Click()mciSendString &open D:\1.mp3 type MPEGVideo alias MP3&, 0, 0, 0mciSendString &play mp3 &, 0, 0, 0End SubPrivate Sub stop_Click()mciSendString &close MP3&, 0, 0, 0End Sub
