Question

VB.net中如何添加声音？

我在用VB.net做个计时器，需要在一定的时间有提示音，请问如何添加？
另外，做好的程序怎么发布啊？我只需要做成一个exe文件即可，不需要做安装程序那么麻烦。但是要求复制到别的电脑上也能用，有没有什么简单的方法啊？
我不说什么了，我只想要一个准确点的回答，不过还是要谢谢你

Answer 1

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

Answer 2

添加一个WindowsMediaPlayer控件放到窗体里，然后写代码：

Private Sub Command1_Click()
WindowsMediaPlayer1.URL = "123.mp3" '这句代码的意思是播放程序所在文件夹中的123.mp3

'URL后面添地址,可以是网址
