当你在用老牌的XingPlay或是华丽的《超级解霸5.0》的时候,你有没有想过拥有一个你自己编写的软解压播放器呢?其实你只要掌握一点VB的技巧,那么要实现这个愿望就变得很简单了。
笔者在初步研究了Windows的SYSTEM.INI后发现，通过VB的多媒体控件MCI.VBX可以打开MPEG压缩文件(如VCD2.0版的.DAT文件)。
首先你的Windows系统中SYSTEM.INI文件关于[MCI]中需有MPEGVideo项(一般Windows95和Windows98中都已有此项,通过安装XingPlay或CCDVP95等软件也可增加此项)。
其次在VB中建立一个新窗口,将MCI.VBX加入ToolBox中,将MCI控件拖放至窗体Form上,调整其大小,将九个按钮(从左至右为:Prev、Next、Play、Pause、Back、Step、Stop、Record和Eject)中Record按钮Visible属性设为False,其余按钮的Visible属性和Enabled属性设置为True,以上按钮的设置可通过MMControl的属性栏内“自定义”项来设置。
假设光驱为E:,VCD碟片文件为E:\MPEGAV\MUSIC01.DAT。
源代码如下：
Private Sub Form_ Load()
MMControl.DeviceType=〃MPEGVideo〃
MMControl.FileName=〃E:\MPEGAV\MUSIC01.DAT〃
MMControl.Command=〃OPEN〃
MMControl.Command=〃PLAY〃
End Sub
Sub Form_Unload(Cancel As Integer)
MMControl.Command=〃close〃
End Sub
笔者通过实践发现Step和Back按钮功能不明显,所以对以上两个按钮进行了一些改进。
Sub MMControl_ StepClick(Cancel As Integer)
j=MMControl.Position＋100 ′数值100为前进量,可适当调整
If jMMControl.Length Then
MMControl.From=MMControl.Length
Else
MMControl.From=j
End If
MMControl.Command=〃Play〃
End Sub
Sub MMControl_ BackClick(Cancel As Integer)
I=MMControl.Position－100 ′数值100为后退量,可适当调整
If I0 Then
MMControl.From=0
Else
MMControl.From=I
End If
MMControl.Command=〃Play〃
End Sub
MCI控件还有很多属性,如画面播放位置hWndDisplay属性等,读者可参阅相关资料自行摸索,这里不再介绍。读者还可以通过建立通用对话框来打开文件,以解决VCD文件名不统一或多文件的问题。
调整好窗体Form的标题、图标、颜色等,然后编译成�EXE文件,你就可以在Windows下拥有自己的VCD播放器了。

方法只是添加一个播放器控件，再改它的属性就可以了.
添加播放器控件的方法：在窗体设计模式中，右键单击”工具箱”－＞”WINDOWS 窗体”，选择”添加／移除项”，再选择”COM组件”标签找到”WINDOWS MEDIA PLAYER”项，选上.最后把添加了控件放到窗体中就行了.
我没有ATI格式的文件也不知道MEDIA PLAYER能放不，不行的话用别的控件试试，比如REALPLAYER.
邮件我已经发过去了.
需要用到COM控件，例如media player、Real player等，或者用 .NET 自带的类库 System.Media下面的 SoundPlayer来播放音乐
