vb.net做音频播放器，如何消除对话框

有点复杂，如果是Excel，有Application.DisplayAlerts=False'这是Excel阻止警告

我粗看了下MediaPlayer没有提供类似的接口，试着用消息捕获的方法看看

Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message) '消息捕获

If m.Msg = H999 Then '这里的值要你自己去测试出来（就是弹出对话框时的值)

SendKeys.Send("{ENTER}") '发送回车键

End If

MyBase.WndProc(m)

End Sub

VB.NET 视频播放器

Windows Media Player 我使用很正常啊，外面单独使用也正常

而且视频播放正不正常其实是调用视频的解码模块来实现的，跟程序本身关系不大

建议你下载“终极解码FinalCodecs”安装后重新尝试Windows Media Player控件

vb.net中编辑音乐播放器用什么控件添加音乐

需要用到COM控件，例如media player、Real player等，或者用 .NET 自带的类库 System.Media下面的 SoundPlayer来播放音乐

简单的播放器用vb.net怎么做啊

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

vb.net制作 mp3播放器

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]可以轻松实现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作，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，在窗体上放置6个命令按钮，三个标签，一个公用对话框、一个进度条、一个状态栏和一个计时器，窗本的布置请参考附图按钮"Open MP3 File"是用来打开对话框选择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(向前跳跃)。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
