程序员 书:VB.net中如何添加声音？

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

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

//c#做的，呵呵
