vb中如何添加背景音乐？

是用windowmediaplayer空间
在工程——部件里面找到
应该在最下面
方法使用
windowmediaplayer1.url="e:\mp3\1.mp3"
放到form_load事件里面
拖进一个Windows
Media
Player控件,
设置其Visible属性为False
然后在Form_Load中用Windows
Media
Player加载你的背景音乐播放就OK了.

WindowsMediaPlayer1.Controls.play'播放
WindowsMediaPlayer1.Controls.stop'停止
WindowsMediaPlayer1.Controls.pause'暂停
你这样连续让它播放\停止\暂停,它最后就是停止了,当然没有声音啦
Private
Sub
WindowsMediaPlayer1_OpenStateChange(ByVal
NewState
As
Long)
WindowsMediaPlayer1.URL
=
"e:\wj\j.mp3"
WindowsMediaPlayer1.Controls.play
End
Sub
就可以了

你不是要加背景音乐吗?
Private
Sub
Form_Load()
WindowsMediaPlayer1.Visible
=
False
WindowsMediaPlayer1.URL
=
"e:\mp3\1.mp3"
End
Sub
这样,那个WindowsMediaPlayer不会出现在你的下雪画面中,又能实现背景音乐的播放了.

'下面仅以播放背景音乐为例
'在窗体代码中复制以下代码，并改变歌曲名称，运行后就会听到美妙的音乐了。
'====窗体代码部分====
Option Explicit
Dim a

Private Sub Form_Load()
Set a = CreateObject("wmplayer.ocx")
a.url = "E:\mp3\花好月圆.mp3" '你可在此改成你的乐曲
a.settings.playCount = 99999
End Sub

Private Sub Form_Unload(Cancel As Integer)
a.Controls.stop
a.Close
Set a = Nothing
End Sub

背景音乐干吗要用控件
api就行了
