    [基本属性]  
    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(不计大小写)
    playState:integer; 播放状态。这个属性改变时同时引发PlayStateChange事件与StateChange事件。取值范围为枚举型:WMPLib.WMPPlayState,它的成员如下:
      wmppsUndefined = 0;   //未知状态
      wmppsStopped = 1;    //播放停止
      wmppsPaused = 2;     //播放暂停
      wmppsPlaying = 3;     //正在播放
      wmppsScanForward = 4;   //向前搜索
      wmppsScanReverse = 5;   //向后搜索
      wmppsBuffering = 6;     //正在缓冲
      wmppsWaiting = 7;      //正在等待流开始
      wmppsMediaEnded = 8;    //播放流已结束
      wmppsTransitioning = 9;    //准备新的媒体文件
      wmppsReady = 10;      //播放准备就绪
      wmppsReconnecting = 11;   //尝试重新连接流媒体数据
      wmppsLast = 12;       //上一次状态,状态没有改变
      在PlayStateChange中写代码可以防止播放rmvb等非默认类型的问题(用wmppsReady)。
      enableContextMenu:Boolean;    启用/禁用右键菜单
      fullScreen:boolean;         是否全屏显示
    
      //播放器基本控制
      Ctlcontrols.play; 播放
      Ctlcontrols.pause; 暂停
      Ctlcontrols.stop; 停止
      Ctlcontrols.currentPosition:double; 当前进度
      Ctlcontrols.currentPositionString:string; 当前进度,字符串格式。如“00:23”
      Ctlcontrols.fastForward; 快进
      Ctlcontrols.fastReverse; 快退
      Ctlcontrols.next; 下一曲
      Ctlcontrols.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
      //顺序播放
      wmp.settings.setMode("shuffle", False)
      //随机播放
      wmp.settings.setMode("shuffle", True)
      //循环播放
      wmp.settings.setMode("loop", True)
    
    [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")
    复制代码

    基本设置实例:

    复制代码
    axWindowsMediaPlayer1.windowlessVideo = false;   //设为false后双击屏幕可以全屏
    axWindowsMediaPlayer1.fullScreen = true; //设播放器全屏播放
    
    axWindowsMediaPlayer1.URL = @"mms://192.168.0.102/vod/jingwei.wma";//播放资源
    
    axWindowsMediaPlayer1.Ctlcontrols.play();        //播放
    axWindowsMediaPlayer1.Ctlcontrols.stop();        //停止
    axWindowsMediaPlayer1.Ctlcontrols.pause();       //暂停
    
    axWindowsMediaPlayer1.settings.autoStart = true;     //自动播放
    
    axWindowsMediaPlayer1.settings.mute = false;         //静音
    axWindowsMediaPlayer1.settings.volume = 100;      // 音量 int 0 ~ 100   100 是最大音量
    
    axWindowsMediaPlayer1.currentMedia.duration.ToString();//影片长度
    axWindowsMediaPlayer1.Ctlcontrols.currentPosition = 30; //当前的播放位置 double
    
    axWindowsMediaPlayer1.currentMedia.getItemInfo("Title");//标题
    axWindowsMediaPlayer1.currentMedia.getItemInfo("Author");//作者

    全屏控制实例代码:
