C#学习之路之使用windows media player 实例

最近，用C#写了个小程序。自娱自乐哈~~~~

调用AxWMPLib库，编写了个4分屏的媒体播放器。

不废话了。先来看看结果。

这里，笔者今天捣鼓了一个下午,完全没招。>M<

这里没有实现 “上一个”， “下一个”， “播放列表”，“剩余时间：”。

若你有很好的关于做好这个 “剩余时间:”，还请指教哈。^_^

~~~~~下面附上代码，在代码的最后，附上源码链接地址~~~

这代码有点长，优化做的不够好。还望毋吐槽呀~~~~

该播放器，Windows media player 的点击事件涉及这个消息：

AxWindowsMediaPlayer.ClickEvent;

笔者使用如下:

this.mediaPlayer1.ClickEvent += new AxWMPLib._WMPOCXEvents_ClickEventHandler(this.mediaPlayer1_ClickEvent);

说明：当点击当前播放屏，将触发WindowsMediaPlayer的ClickEvent消息。上面的this.mediaPlayer1.ClickEvent 是对应点击事件的消息处理函数。可在上面的那段长代码段中找到对应的消息事件处理。
