搞定了,嘿嘿!首先非常感谢zoujiaming在邮件中给我指了条路:用C#调用API搞定!!!
使用的是mciSendString API函数
主要参考了zoujiaming 给我的邮件(再次感谢啊!!)
以及http://www.csdn.net/Develop/Read_Article.asp?Id=16269
和http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/htm/_win32_mcisendstring.asp
下面是我的一个简单实验代码,通过双击PictureBox播放我机子上的一个视频文件。
有什么问题可以跟贴:)
