vb.net调用beep vbnet console

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vb.net调用beep你要播放vb.net调用beep的声音文件vb.net调用beep的路径

Q1: VB.net如何加载音效？

方法一：调用系统DLL（这个有点不完善，也就是播放声音时窗体无法控制，效果相当于Enabled=true，但音频播放完毕后就没事了）

    Private Declare Function sndPlaySound Lib "Winmm.dll" Alias "sndPlaySoundA" (ByVal lpszSoundName As String, ByVal uFlags As Long) As Long

    

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        Dim SoundFile As String, Result As Long

        SoundFile = "D:\KuGou\Pianoboy - 第105天.wav" '此处为路径

        Result = sndPlaySound(SoundFile, 0)

    End Sub

方法二：使用WindowsMediaPlayer（WindowsMediaPlayer1的可见为False）

先添加一个windowsmediaplayer控件（工具箱里没有，需要手动添加）

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

WindowsMediaPlayer1.visible=False

Me.WindowsMediaPlayer1.URL = "D:\KuGou\Pianoboy - 第105天.mp3"

End Sub

上面的都是点击button1（按钮1）后播放声音，若是鼠标移动到某控件上发出声音的话改一下触发事件就OK了。

Q2: VB.NET中播放背景音乐最简单的办法是什么啊?

给你我的程序，自己研究一下吧，我也不是很明白。

Public Class Form1

Private Declare Auto Function PlaySound Lib "winmm.dll" (ByVal lpszSoundName As String, ByVal hModule As Integer, ByVal dwFlags As Integer) As Integer

Const SND_filename As Integer = H20000

Const SND_alias As Integer = H10000

Const SND_sync As Integer = H0

Declare Auto Function waveOutGetNumDevs Lib "winmm.dll" Alias "waveOutGetNumDevs" () As Integer

Declare Auto Function sndPlaySound Lib "winmm.dll" (ByVal filename As String, ByVal options As Integer) As Integer

Private Const SND_memory As Integer = H4

Private Const SND_async As Integer = H1

Private Const proess_domain As String = ""

Const SND_sync1 = H0

Const SND_async1 = H1

Const SND_nodefault = H2

Const SND_loop = H8

Const SND_nostop = H10

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Beep()

End Sub

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

Dim strFileName As String = "start.wav"

PlaySound(strFileName, 0, SND_filename)

End Sub

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click

PlaySound("systemstart", 0, SND_alias Or SND_sync)

End Sub

Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click

Dim ret As Long

Dim strfilename As String

strfilename = "start.wav"

ret = sndPlaySound(strfilename.ToCharArray, 0)

End Sub

Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click

Dim i As Integer

i = waveOutGetNumDevs()

If i 0 Then

MsgBox("可以播放声音", 64, "检测")

Else

MsgBox("不能播放声音", 64, "检测")

End If

End Sub

End Class

Q3: 我在VB.net程序中加了Beep没有用！

用Console.Beep(int,int)这个方法就可以了。

另外，建议把提示出错的代码直接放入Catch中，提示鸣放的代码放入Try中。

Q4: vb.net的一个问题

蜂鸣器编程vb.net调用beep的话，有个API函数，VB中的声明为

Declare Function Beep Lib "kernel32" Alias "Beep" (ByVal dwFreq As Long, ByVal dwDuration As Long) As Long

调用方法是Beep 声音频率,持续时间（毫秒为单位）

比如 beep 2000,1000

如果是声卡编程的话，也有相应的API函数，比如你可以用DirectSound(也就是DirectX的一部分)，功能比较强大，也很专业。事实上，如果你使用的是专业级的声卡和音响设备，它可以在一定范围内回放出超出人耳听觉范围的声音。当然也可以用简单一点的API，以下是几个需要的函数：

Private Declare Function midiOutGetDevCaps Lib "winmm.dll" Alias "midiOutGetDevCapsA" (ByVal uDeviceID As Long, lpCaps As MIDIOUTCAPS, ByVal uSize As Long) As Long

Private Declare Function midiOutGetNumDevs Lib "winmm" () As Integer

Private Declare Function MIDIOutOpen Lib "winmm.dll" Alias "midiOutOpen" (lphMidiOut As Long, ByVal uDeviceID As Long, ByVal dwCallback As Long, ByVal dwInstance As Long, ByVal dwFlags As Long) As Long

Private Declare Function midiOutClose Lib "winmm.dll" (ByVal hMidiOut As Long) As Long

Private Declare Function midiOutShortMsg Lib "winmm.dll" (ByVal hMidiOut As Long, ByVal dwMsg As Long) As Long

Private Declare Function midiOutGetErrorText Lib "winmm.dll" Alias "midiOutGetErrorTextA" (ByVal err As Long, ByVal lpText As String, ByVal uSize As Long) As Long

Private Const MAXERRORLENGTH = 128 ' max error text length (including NULL)

Private Const MIDIMAPPER = (-1)

Private Const MIDI_MAPPER = (-1)

'MIDIOUTCAPS结构描述vb.net调用beep了Musical Instrument Digital Interface(MIDI)输入设备的性能

Type MIDIOUTCAPS

wMid As Integer

wPid As Integer ' 产品 ID

vDriverVersion As Long ' 设备版本

szPname As String * 32 ' 设备 name

wTechnology As Integer ' 设备类型

wVoices As Integer

wNotes As Integer

wChannelMask As Integer

dwSupport As Long

End Type

Public Sub note_on(ch As Integer, ByVal kk As Integer, v As Integer)

' 发音主函数。参数分别为通道编号，音调，速度

Call midi_outshort(H90 + ch, kk, v)

End Sub

Sub midi_outshort(b1 As Integer, b2 As Integer, b3 As Integer)

Dim midi_error As Integer

midi_error = midiOutShortMsg(hMidi, b3 * H10000 + b2 * H100 + b1)

If Not midi_error = 0 Then

Call midi_outerr(midi_error)

End If

End Sub

Sub midi_outerr(ByVal midi_error As Integer)

Dim s As String

Dim x As Integer

s = Space(MAXERRORLENGTH)

x = midiOutGetErrorText(midi_error, s, MAXERRORLENGTH)

MsgBox s

End Sub
