第一种是在apsx页面上放一个Lable控件
这种方式可以写javascript等控制页面，和布局页面如下：HTML页面代码：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<TITLE>多媒体播放页面</TITLE>
<meta content="Microsoft Visual Studio .NET 7.1" name="GENERATOR">
<meta content="C#" name="CODE_LANGUAGE">
<meta content="javascript" name="vs_defaultClientScript">
<meta content="http://schemas.microsoft.com/intellisense/ie5" name="vs_targetSchema">
</HEAD>
<BODY ms_positioning="GridLayout" bottomMargin=10 topMargin=10>
<FORM id="Form1" method="post" runat="server">
<asp:Label id="lbl_MediaPlayer" style="Z-INDEX: 101; LEFT: 8px; POSITION: absolute; TOP: 8px"
runat="server" Width="104px"></asp:Label>
</FORM>
</BODY>
</HTML>
.cs页面代码：
private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
if(!this.IsPostBack)
{
this.lbl_MediaPlayer.Text = this.PlayMedia(filename);
}
}
public string PlayMedia(string MediaFile)
{
string strScript =
"<TABLE id=/"Table2/" align=/"center/" border=/"0/" runat=/"server/" width = '620' height ='450'>"
+"<TR>"
+"<TD align=/"center/">"
+"<OBJECT id=/"mdpTrailer/" classid=/"clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95/" name=/"mdpTrailer/" width='620' height = '450'>"
+"<PARAM NAME=/"AudioStream/" VALUE=/"-1/">"
+"<PARAM NAME=/"AutoSize/" VALUE=/"-1/">"
+"<PARAM NAME=/"AutoStart/" VALUE=/"-1/">"
+"<PARAM NAME=/"AnimationAtStart/" VALUE=/"-1/">"
+"<PARAM NAME=/"AllowScan/" VALUE=/"-1/">"
+"<PARAM NAME=/"AllowChangeDisplaySize/" VALUE=/"-1/">"
+"<PARAM NAME=/"AutoRewind/" VALUE=/"0/">"
+"<PARAM NAME=/"Balance/" VALUE=/"0/">"
+"<PARAM NAME=/"BaseURL/" VALUE=/"/">"
+"<PARAM NAME=/"BufferingTime/" VALUE=/"5/">"
+"<PARAM NAME=/"CaptioningID/" VALUE=/"/">"

+"<PARAM NAME=/"Enabled/" VALUE=/"-1/">"
+"<PARAM NAME=/"EnableContextMenu/" VALUE=/"-1/">"
+"<PARAM NAME=/"EnablePositionControls/" VALUE=/"-1/">"
+"<PARAM NAME=/"EnableFullScreenControls/" VALUE=/"0/">"
+"<PARAM NAME=/"EnableTracker/" VALUE=/"-1/">"
+"<PARAM NAME=/"Filename/" VALUE=/""+ MediaFile + "/">"
+"<PARAM NAME=/"InvokeURLs/" VALUE=/"-1/">"
+"<PARAM NAME=/"Language/" VALUE=/"-1/">"
+"<PARAM NAME=/"Mute/" VALUE=/"0/">"
+"<PARAM NAME=/"PlayCount/" VALUE=/"1/">"

+"<PARAM NAME=/"SendKeyboardEvents/" VALUE=/"0/">"
+"<PARAM NAME=/"SendMouseClickEvents/" VALUE=/"0/">"
+"<PARAM NAME=/"SendMouseMoveEvents/" VALUE=/"0/">"
+"<PARAM NAME=/"SendPlayStateChangeEvents/" VALUE=/"-1/">"
+"<PARAM NAME=/"ShowCaptioning/" VALUE=/"0/">"
+"<PARAM NAME=/"ShowControls/" VALUE=/"-1/">"
+"<PARAM NAME=/"ShowAudioControls/" VALUE=/"-1/">"
+"<PARAM NAME=/"ShowDisplay/" VALUE=/"0/">"
+"<PARAM NAME=/"ShowGotoBar/" VALUE=/"0/">"
+"<PARAM NAME=/"ShowPositionControls/" VALUE=/"-1/">"
+"<PARAM NAME=/"ShowStatusBar/" VALUE=/"0/">"
+"<PARAM NAME=/"ShowTracker/" VALUE=/"-1/">"
+"<PARAM NAME=/"TransparentAtStart/" VALUE=/"0/">"

+"<PARAM NAME=/"Volume/" VALUE=/"-600/">"
+"<PARAM NAME=/"WindowlessVideo/" VALUE=/"0/">"
+"</OBJECT>"
+"</TD>"
+"</TR>"
+"</TABLE>";
return strScript;
}
第二种方式是直接在aspx页面放置播放器代码
Html代码：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<TITLE>多媒体播放页面</TITLE>
<meta content="Microsoft Visual Studio .NET 7.1" name="GENERATOR">
<meta content="C#" name="CODE_LANGUAGE">
<meta content="javascript" name="vs_defaultClientScript">
<meta content="http://schemas.microsoft.com/intellisense/ie5" name="vs_targetSchema">
</HEAD>
<BODY ms_positioning="GridLayout" bottomMargin=10 topMargin=10>
<FORM id="Form1" method="post" runat="server">
<object id="MediaPlayer1" classid="clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95" width="620" height="460" VIEWASTEXT>
<param name="filename" value="<%=PlayUrl%>">
<param name="AutoStart" value="1">

<param name="BaseURL" value="">
<param name="BufferingTime" value="5">
<param name="CaptioningID" value="">
<param name="ClickToPlay" value="-1">
<param name="CursorType" value="0">
<param name="CurrentPosition" value="-1">
<param name="CurrentMarker" value="0">
<param name="DefaultFrame" value="">
<param name="DisplayBackColor" value="0">
<param name="DisplayForeColor" value="16777215">
<param name="DisplayMode" value="0">
<param name="InvokeURLs" value="-1">
<param name="Language" value="-1">
<param name="Mute" value="0">
<param name="PlayCount" value="1">
<param name="PreviewMode" value="0">
<param name="Rate" value="1">
<param name="SAMILang" value="">
<param name="SAMIStyle" value="">
<param name="SAMIFileName" value="">
<param name="SelectionStart" value="-1">
<param name="SelectionEnd" value="-1">
<param name="SendOpenStateChangeEvents" value="-1">
<param name="SendWarningEvents" value="-1">
<param name="SendKeyboardEvents" value="0">
<param name="SendMouseClickEvents" value="0">
<param name="SendMouseMoveEvents" value="0">
<param name="SendPlayStateChangeEvents" value="-1">
<param name="ShowCaptioning" value="0">
<param name="ShowAudioControls" value="-1">
<param name="ShowDisplay" value="0">
<param name="ShowPositionControls" value="-1">
<param name="ShowTracker" value="-1">
<param name="TransparentAtStart" value="0">
<param name="VideoBorderWidth" value="0">
<param name="VideoBorderColor" value="0">
<param name="VideoBorder3D" value="0">
<param name="WindowlessVideo" value="0">
</object>
</FORM>
</BODY>
</HTML>
.CS页面
private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
if(!this.IsPostBack)
{
int picID=System.Convert.ToInt32(Request.QueryString["pid"]);
MyNature.SQLServerDAL.Picture pic = new MyNature.SQLServerDAL.Picture();
string filename = pic.GetMulname(picID);
PlayUrl = filename；
}
}
+"<PARAM NAME=/"EnableFullScreenControls/" VALUE=/"0/">"
改为
+"<PARAM NAME=/"EnableFullScreenControls/" VALUE=/"1/">"
