怎样用vb实现windowsmediaplayer自动顺序播放

Answer 1

认真研究一下它的常用功能
[基本属性]
URL:string 可以指定媒体位置
enableContextMenu:Boolean 显示/不显示播放位置的右键菜单
fullScreen:boolean 全屏显示
stretchToFit:boolean 非全屏状态时是否伸展到最佳大小
uMode:string 播放器的模式，full：有下面的控制条; none：只有播放部份没有控制条
playState:integer 当前控件状态，状态变化时会触发OnStatusChange事件

[controls]
可通过WindowsMediaPlayer.controls对播放器进行控制并取得相关的一些信息：
controls.play; 播放
controls.stop; 停止
controls.pause; 暂停
controls.currentPosition：Double 当前播放进度
controls.currentPositionString：string 时间格式的字符串 "0:32"

[currentMedia]
可以通过WindowsMediaPlayer.currentMedia取得当前媒体的信息
currentMedia.duration Double 总长度
currentMedia.durationString 时间格式的字符串 "4:34"

[settings]
可以通过WindowsMediaPlayer.settings对播放器进行设置，包括音量和声道等。
settings.volume:integer 音量 （0-100）
settings.balance:integer 声道，通过它应该可以进行立体声、左声道、右声道的控制。
