播放器

1、windows Media Player：（ie专用）

属性/方法名：	说明：
URL:String;	指定媒体位置，本机或网络地址
uiMode:String;	播放器界面模式，可为Full, Mini, None, Invisible
playState:integer;	播放状态，1=停止，2=暂停，3=播放，6=正在缓冲，9=正在连接，10=准备就绪
enableContextMenu:Boolean;	启用/禁用右键菜单
fullScreen:boolean;	是否全屏显示
[controls]	wmp.controls //播放器基本控制
controls.play;	播放
controls.pause;	暂停
controls.stop;	停止
controls.currentPosition:double;	当前进度
controls.currentPositionString:string;	当前进度，字符串格式。如“00:23”
controls.fastForward;	快进
controls.fastReverse;	快退
controls.next;	下一曲
controls.previous;	上一曲
[settings]	wmp.settings //播放器基本设置
settings.volume:integer;	音量，0-100
settings.autoStart:Boolean;	是否自动播放
settings.mute:Boolean;	是否静音
settings.playCount:integer;	播放次数
[currentMedia]	wmp.currentMedia //当前媒体属性
currentMedia.duration:double;	媒体总长度
currentMedia.durationString:string;	媒体总长度，字符串格式。如“03:24”
currentMedia.getItemInfo(const string);	获取当前媒体信息"Title"=媒体标题，"Author"=艺术家，"Copyright"=版权信息，"Description"=媒体内容描述，"Duration"=持续时间（秒），"FileSize"=文件大小，"FileType"=文件类型，"sourceURL"=原始地址
currentMedia.setItemInfo(const string);	通过属性名设置媒体信息
currentMedia.name:string;	同 currentMedia.getItemInfo("Title")
[currentPlaylist]	wmp.currentPlaylist //当前播放列表属性
currentPlaylist.count:integer;	当前播放列表所包含媒体数
currentPlaylist.Item[integer];	获取或设置指定项目媒体信息，其子属性同wmp.currentMedia

问题一：播放后（axWindowsMediaPlayer1.currentMedia.duration）无法及时获取播放文件的总时间

方案：使用 axWindowsMediaPlayer1.newMedia(URL).duration （获取的是总的毫秒数，url为播放文件的路径。）
