VB6播放音乐文件改为播放avi视频文件代码如何改？
这是原来的代码：
Private Sub Command4_Click()
WindowsMediaPlayer1.URL = App.Path + "/mi/12.mid"
WindowsMediaPlayer1.settings.playCount = &H7FFFFFFF '上一首连续播放
    Command9.Visible = True '换钮
       Command4.Visible = False
End Sub
现在要将12.mid音乐文件改为视频文件12.avi
直接改为12.avi通不过，请问高手这要如何改？

可以听到声音，但看不到播放图像，不知何故？

给代码及实例媒体文件，通常会有大神帮你弄出来的。

这页的全部代码：就是想将音乐换成视频；

视频文件我是用KK屏幕录像软件随便录了一段，就是想在这页面上能不能播放视频，现在是声音能出来，就是没有播放窗口
这个页面也有播放视频的按钮，那是联到网站上的链接，现在是想让软件自带视频节目

第十五届奥运会邮票集软件

这个真没做过，帮顶

能看到视频，你的WindowsMediaPlayer尺寸过小，还必须要有视频文件，帮你弄个12.avi的视频，并调整WindowsMediaPlayer尺寸和位置后，你运行即可看到效果，原理搞清后，如何添置自己需要的代码，你自己弄吧，祝编程快乐！

谢谢版主的帮助
