VB.net中如何添加声音？
Private Declare Function mciExecute Lib "winmm.dll" (ByVal lpstrCommand As String) As Long
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Call mciExecute("play F:\MUSIC\WMA\guitar\强调乐队-无声的叹息.mp3 ")
End Sub
复制可不怎么好吧,那些dll你都要有才行,vb.net做安装程序也不麻烦,只要添加一个新项目--安装向导,根据提示按下去就是了
哎~~~都说得很清楚了,你还......再给个提示吧,用timeofday来提取当前时间,和自定义时间对比

Q1: 想在vb.net的程序中有一个语音提示，该怎么写
首先添加一个系统.netvb播放提示音的语音COM组件的引用microsoft speech object library然后在程序中声明一个语音类dim RC As SpeechLib.SpSharedRecoContext这个类有一些事件,如果.netvb播放提示音你要处理它的一些事件,可以用withevent来声明然后在窗体LOAD事件或你需要的地方先创建一个实例RC = New SpeechLib.SpSharedRecoContext当一个RC被实例化后,系统就会运行语音识别程序.前提是你的系统已经正确安装这个功能.一般默认就已经安装好的.其次提醒一下,WIN7的语音识别比XP的好N倍.从阅读到侦听都好很多.然后就可以在你需要阅读的地方使用RC.Voice.Speak("hello .netvb播放提示音我", 11)11那里是一些枚举,用来标识系统用前台还是后台或其.netvb播放提示音他方式来阅读文字,简单的来说就是阅读的时候不会卡住你的程序.你可以选其他的枚举来试试作用.以上为阅读部分.如果需要程序听你说话,则需要声明一个侦听类dim RG As SpeechLib.ISpeechRecoGrammar在初始化时将之与上面的RC建立关系,此时则必须要用withevent来声明上面的RC,因为涉及电脑听到你的语音后,会触发一个事件,并将听到的内容传递到该事件.其次,要让系统听到的解析为命令,就必须准备一个XML结构的文件来保存那些固定的命令.如果电脑在XML文件中找不到那些固定命令或同时不属于系统命令,电脑将会将其解释为听写.RG = RC.CreateGrammar '(0)
RG.CmdLoadFromFile("听到.xml", SpeechLib.SpeechLoadOption.SLODynamic)
RG.CmdSetRuleIdState(0, SpeechLib.SpeechRuleState.SGDSActive)然后写一个过程来处理听到的事件Private Sub 听到命令(ByVal StreamNumber As Integer, ByVal StreamPosition As Object, ByVal RecognitionType As SpeechLib.SpeechRecognitionType, ByVal 话语 As SpeechLib.ISpeechRecoResult) Handles RC.Recognition RC.Voice.Speak("我听到.netvb播放提示音了" 话语.PhraseInfo.GetText, 11)End Sub以上为侦听部分.下面列一个XML的例文?xml version="1.0" encoding="gb2312"?
GRAMMAR LANGID="804"
RULE NAME="命令" TOPLEVEL="ACTIVE"
L
P打开播放器
P上我的QQ
P关闭你自己 /L
/RULE
/GRAMMAR要让系统正确地侦听到你说的话,前提你必须运行语音识别程序并让其激活到"正在聆听"状态.并且你必须有一个能正常使用的话筒而且保证话筒已经打开.(废话-_-|||)以上就是用VB.NET语音识别的最基本的一些操作.希望对你有帮助.更深入的内容有兴趣的话可以和我一起研究.
Q2: vb.net 控件添加声音
建一个窗体，里面添加一个按钮，代码里拷入下面的代码，运行后，单击按钮
Private Declare Function sndPlaySound Lib "winmm.dll" Alias "sndPlaySoundA" (ByVal lpszSoundName As String, ByVal uFlags As Long) As Long
Private Const SND_ASYNC = H1 '异步播放
Private Const SND_SYNC = H0 '同步播放 （缺省）
Private Sub Command1_Click()
Dim SoundFile As String, Result As Long
SoundFile = "c:\Windows\Media\chord.wav"
Result = sndPlaySound(SoundFile, SND_ASYNC)
End Sub
说明：
要播放不同的声音，例如0-9，你找到相应的wav文件，编程实现就可以了。
PS:没注意到你是VB.NET,上面的代码是VB6的，生成工程文件，直接用.NET打开并自动转换，也可以使用。
Q3: 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。
Q4: VB.NET问题，做一个定时响铃提醒程序，怎样在程序中引用铃音，请写写代码，是在timer中添加代码吗
把类似下面的三行代码放入timer即可。关键是放音程序。
DealWav.mciSendString "open " sA " alias wav", sB, Len(sB), 0
DealWav.mciSendString "play wav ", sB, Len(sB), 0
DealWav.mciSendString "close wav ", sB, Len(sB), 0
