　　在给客户做个程序时,突然遇到个问题,就是产品页用户提交视频播放文件时,如何根据提交的网址内的视频格式进行正确的播放呢....郁闷了一会,想好了思路,说动手就动手...

　　思路是先取得文件的类型,并根据类型选择不同的网页播放器代码..三下五去二.....同时为了代码在以后的复用性,写成了通用的调用函数.方便以后在别的系统中调用..

　　现发布源代码如下:

Sub SelPlay(strUrl,strWidth,StrHeight)
Dim Exts,isExt
If strUrl <> "" Then
　 isExt = LCase(Mid(strUrl,InStrRev(strUrl, ".")+1))
Else
　 isExt = ""
End If
Exts = "avi,wmv,asf,mov,rm,ra,ram"
If Instr(Exts,isExt)=0 Then
Response.write "非法视频文件"
Else
Select Case isExt
　Case "avi","wmv","asf","mov"
　 Response.write "<EMBED id=MediaPlayer src="&strUrl&" width="&strWidth&" height="&strHeight&" loop=""false"" autostart=""true""></EMBED>"
　Case "mov","rm","ra","ram"
　 Response.Write "<OBJECT height="&strHeight&" width="&strWidth&" classid=clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA>"
　 Response.Write "<PARAM NAME=""_ExtentX"" VALUE=""12700"">"
　 Response.Write "<PARAM NAME=""_ExtentY"" VALUE=""9525"">"
　 Response.Write "<PARAM NAME=""AUTOSTART"" VALUE=""-1"">"
　 Response.Write "<PARAM NAME=""SHUFFLE"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""PREFETCH"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""NOLABELS"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""SRC"" VALUE="""&strUrl&""">"
　 Response.Write "<PARAM NAME=""CONTROLS"" VALUE=""ImageWindow"">"
　 Response.Write "<PARAM NAME=""CONSOLE"" VALUE=""Clip"">"
　 Response.Write "<PARAM NAME=""LOOP"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""NUMLOOP"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""CENTER"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""MAINTAINASPECT"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""BACKGROUNDCOLOR"" VALUE=""#000000"">"
　 Response.Write "</OBJECT>"
　 Response.Write "<BR>"
　 Response.Write "<OBJECT height=32 width="&strWidth&" classid=clsid:CFCDAA03-8BE4-11cf-B84B-0020AFBBCCFA>"
　 Response.Write "<PARAM NAME=""_ExtentX"" VALUE=""12700"">"
　 Response.Write "<PARAM NAME=""_ExtentY"" VALUE=""847"">"
　 Response.Write "<PARAM NAME=""AUTOSTART"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""SHUFFLE"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""PREFETCH"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""NOLABELS"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""CONTROLS"" VALUE=""ControlPanel,StatusBar"">"
　 Response.Write "<PARAM NAME=""CONSOLE"" VALUE=""Clip"">"
　 Response.Write "<PARAM NAME=""LOOP"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""NUMLOOP"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""CENTER"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""MAINTAINASPECT"" VALUE=""0"">"
　 Response.Write "<PARAM NAME=""BACKGROUNDCOLOR"" VALUE=""#000000"">"
　 Response.Write "</OBJECT>"
End Select
End If
End Sub
