vb.net播放器按钮,vb音乐播放控件

如何在VB.NET中调用MP3播放器

工具栏里选择"添加,删除组件"

选择com组件

选择"Windows Media Player "

然后在界面上加入这个组件

代码

Private Sub Button1_Click(ByVal sender As System.Object, _

ByVal e As System.EventArgs) _

Handles Button1.Click

Const DATA_FILE_EXTENSION As String = ".mp3"

Dim dlgFileDialog As New OpenFileDialog

With dlgFileDialog

.Filter = DATA_FILE_EXTENSION _

" files (*" DATA_FILE_EXTENSION "|*" DATA_FILE_EXTENSION

.FilterIndex = 1

.RestoreDirectory = True

If .ShowDialog() = DialogResult.OK Then

'Play the sound file

Me.AxWindowsMediaPlayer1.URL = dlgFileDialog.FileName

End If

End With

End Sub

参考资料中可以看到很详细的步骤

Q1: vb.net内嵌的视频怎么用media player控件播放啊？

“工具箱”中单击右键，选择“选择项”菜单，打开“选择工具箱项”窗口，选择“COM组件”标签，在列表中找到并勾选“Windows Media Player”组件，单击“确定”按钮。将该组件添加到指定的工具箱选项卡中，然后在工具箱里面找 Windows Media Player 控件，拉到form里面，拉出来的控件就是AxWindowsMediaPlayer

Q2: 用VB.NET编多媒体播放器

我这里有一段前段时间写的测试代码，使用WMPLib类，中间有你需要的功能，你可以参考下:

使用wmp.currentMedia.duration和wmp.currentMedia.durationString分别以double和string获得当前媒体的播放时间，使用wmp.settings.volume设置音量大小，使用wmp.controls.currentPosition设置当前播放时间点

Imports WMPLib

Public Class FrmMain

Dim WithEvents wmp As WMPLib.WindowsMediaPlayer

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

wmp = New WMPLib.WindowsMediaPlayer()

TextBox1.Text = TextBox1.Text vbCrLf "当前播放状态:" wmp.status

wmp.uiMode = "Mini"

wmp.settings.balance = 1

wmp.enableContextMenu = True

wmp.fullScreen = False

wmp.windowlessVideo = True

wmp.enabled = True

Dim wmpMediaList As IWMPPlaylist = wmp.newPlaylist("默认播放列表", "")

Dim wmpMedia As IWMPMedia = wmp.newMedia(My.Computer.FileSystem.CurrentDirectory "\Human.mp3")

With wmpMediaList

.appendItem(wmpMedia)

End With

'wmp.URL = "\\192.168.1.247\sharoncn\music\Human.mp3"

wmp.currentMedia = wmpMedia

wmp.settings.autoStart = True

tBarPlay.Value = 0

ListBox1.Items.Add(wmpMediaList.name)

ListBox1.SelectedIndex = 0

ListBox2.Items.Add(wmpMediaList.Item(0).name)

ListBox2.SelectedIndex = 0

tbar.Maximum = 100

tbar.Value = 50

Timer1.Enabled = True

Timer1.Interval = 100

End Sub

Private Sub wmp_PlayStateChange(ByVal NewState As Integer) Handles wmp.PlayStateChange

tBarPlay.Maximum = wmp.currentMedia.duration * 10

Label1.Text = "总时间:" wmp.currentMedia.durationString

TextBox1.Text = TextBox1.Text vbCrLf "当前播放状态：" NewState

If NewState = 1 Then

wmp.controls.play()

End If

End Sub

Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged

TextBox1.SelectionStart = Len(TextBox1.Text)

TextBox1.ScrollToCaret()

End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

Label2.Text = "当前播放进度:" wmp.controls.currentPositionString

tBarPlay.Value = CInt(wmp.controls.currentPosition * 10)

End Sub

Private Sub tbar_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tbar.Scroll

wmp.settings.volume = tbar.Value

End Sub

Private Sub tBarPlay_Scroll(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tBarPlay.Scroll

wmp.controls.currentPosition = tBarPlay.Value / 10

End Sub

End Class

Q4: vb.net中如何播放声音，是要什么控件嘛？

My.Computer.Audio.Play("SoundFile.wav")

SoundFile.wav是你要播放的声音文件的路径
