In ASP.Net having Windows Media Player With VB.Net?

[Shashikant]

Hi,
In ASP.Net having Windows Media Player With VB.Net?

I have this page in ASP.Net & I have placed windows Media player in it.
Now what I am looking for is there any way i can send the Play Command to the WMP from the code behind file (VB.NEt)?

AND

I want to know the controls of the player & player.controls.currentPosition value

Please help me with the same!

I'm building a section of a website to show streaming videos. There's a lot more logic involved, but the jist of it all is the video id is pulled as a session variable, but before the video is played, a random ad is played beforehand (based on the topic of the video).

I use 3 pages for this.

The main .aspx page has the following:

<object classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" id="VIDEO" type="video/x-ms-asf"
            width="400" height="365" standby="Loading Microsoft Windows Media Player components..."
            codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,4,5,715">
            <param name="StretchToFit" value="1" />
            <param name="AutoStart" value="true" />
            <param name="Balance" value="0" />
            <param name="EnableContextMenu" value="1" />
            <param name="Enabled" value="1" />
            <param name="EnableErrorDialogs" value="1" />
            <param name="WindowlessVideo" value="0" />
            <param name="Rate" value="1.000" />
            <param name="CurrentPosition" value="0.000" />
            <param name="CurrentMarker" value="1" />
            <param name="FullScreen" value="0" />
            <param name="Mute" value="0" />
            <param name="PlayCount" value="1" />
            <param name="Uimode" value="Full" />
            <param name="Volume" value="50" />
            <param name="URL"  value ="<%Response.Write(strPlay) %> "/>
            <embed id="mpFAB" type="video/x-ms-asf" src="<%Response.Write(strPlay) %>" width="400" height="345"
                showcontrols="1" />
           
           
        </object>

The code behind (.aspx.vb) sets the variable for the URL after several queries as such:

   strPlay = "/MediaList.aspx?u=" & (strUnderwriter) & "&ut=" & (strUTitle) & "&v=" & (strURL) & "&vt=" & (strVTitle)

Finally, the playlist (MediaList.aspx) contains the following code:

<%@ Page Language="VB" %>

<script runat="server">

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

    Dim strUnderwriter As String
    strUnderwriter = Request.QueryString("u")
   
    Dim strURL As String
    strURL = Request.QueryString("v")
   
    Dim strUTitle As String
    strUTitle = Request.QueryString("ut")
     
    Dim strVTitle As String
    strVTitle = Request.QueryString("vt")


 
        Response.ContentType = "video/x-ms-asf"
        Response.Expires = 0

 
 
    Response.Write("<ASX version=""3.0"">")
    Response.Write("<ENTRY CLIENTSKIP=""NO"">")
    Response.Write("<TITLE>" & (strUTitle) & "</TITLE>")
    Response.Write("<COPYRIGHT> 2008 </COPYRIGHT>")
    Response.Write("<ref href = """ & (strUnderwriter) & """ />")
    Response.Write("</ENTRY>")
    Response.Write("<ENTRY>")
    Response.Write("<TITLE>" & (strVTitle) & "</TITLE>")
    Response.Write("<ref href =""" & (strURL) & """ />")
    Response.Write("<COPYRIGHT> 2008 </COPYRIGHT>")
    Response.Write("</ENTRY>")
    Response.Write("</ASX>")

   

    End Sub
</script>

Ok, here's the solution I have come up with:

Here are the key points to get it to work (lots of trial and error went into my discovering this):

1) YOU MUST HAVE THE OBJECT TAGS REPRESENTING THE PLAYER, ABOVE THE <Form></Form> Tags that Visual Studio creates in the ASPX page. You must MANUALLY edit the HTML of the aspx, then simply cut <object></object> tags (and everything between them) and past them in the code above the <form> tag

Like so:

<OBJECT id="Player1" style="Z-INDEX: 104; LEFT: 337px; WIDTH: 245px; POSITION: absolute; TOP: 9px; HEIGHT: 176px" classid="clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6" VIEWASTEXT>
      <PARAM NAME="URL" VALUE="">
      <PARAM NAME="rate" VALUE="1">
      <PARAM NAME="balance" VALUE="0">
      <PARAM NAME="currentPosition" VALUE="0">
      <PARAM NAME="defaultFrame" VALUE="">
      <PARAM NAME="playCount" VALUE="1">
      <PARAM NAME="autoStart" VALUE="-1">
      ...
      </OBJECT>
<FORM id="Form1" method="post" runat="server">
...

[The important thing here is that the Object representing the media player is outside the <Form> tags which get run at the server]

2) You need to manaully add:  id="Player1"  to the <object tag>

3) You then create a server side script that references the id created in step 2) like: Player.URL = filename.wav
3a) create a button or some trigger that launches that script

For my own script I wanted to set the value of the filename dymanically based on a date field coming from a datagrid. So I created an image button in a template column in the datagrid:

<asp:TemplateColumn HeaderText="Play">
     <HeaderStyle Width="1%"></HeaderStyle>
     <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle"></ItemStyle>
          <ItemTemplate>
               <asp:ImageButton id="PlayButton" runat="server" ImageUrl=".\images\playbutton.bmp" CommandName="play" AlternateText="Play" ImageAlign="Middle"></asp:ImageButton>
          </ItemTemplate>
</asp:TemplateColumn>

[the important thing here is that the CommandName is "play" which is in the aspx.vb code behind page:]

Private Sub DataGrid1_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid1.ItemCommand
        Select Case e.CommandName
            Case "play"
                Dim path, filename As String
                path = PathToWMAs 'this is a form wide string variable set elsewhere
                filename = Format(CDate(e.Item.Cells(2).Text), "MMddyy") & ".wma"
                filename = Server.UrlPathEncode(path & filename)
                TextBox1.Text = filename

                'create the script that gets triggered by the <Body> tag's OnLoad parameter
                Dim strScript As String
                strScript = "<script language=JavaScript>"
                strScript = strScript + "function playMe()"
                strScript = strScript + "{"
                strScript = strScript + "Player1.URL =""" & filename & """;"
                strScript  strScript + "return confirm(""" & filename & """);"
                strScript = strScript + "}"
                strScript = strScript + "</script>"
                Page.RegisterStartupScript("ClientScript", strScript)

        End Select

    End Sub

[Important thing here to note is that 1) I used the RegisterStartUpStript to create a script after the form HTML is spit out by server which allows me to change which filename gets loaded dynamically 2) the function i thus created is called by the body's onLoad parameter:]

<BODY onLoad="playMe()" MS_POSITIONING="GridLayout">

You can either user <img> or <object> to embed movies in *.aspx. But to capture the events, you should use the later

Use the below <object tag> to embed WMP in .aspx / html pages

<object id="VIDEO" width="100%" height="100%"
classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6"
type="application/x-oleobject">
<param name="URL" value="http://localhost/QaQcTraining/movies/start.wmv" />
<param name="SendPlayStateChangeEvents" value="True" />
<param name="AutoStart" value="True" />
<param name="uiMode" value="none" />
<param name="windowlessVideo" value="True" />
<param name="stretchToFit" value="true" />
</object<

Now, use the below script to capature the events of WMP
<script language=jscript FOR = VIDEO EVENT = playStateChange(NewState) type=text/jscript>
// Test for the player current state, display a message for each.
switch (NewState){
case 1:
//myText.value = "Stopped";
//alert('stoped');
location.href="qform.aspx";
//redirecting to different page after the movie plays
break;

case 2:
//myText.value = "Paused";
//alert('paused');
break;

case 3:
//myText.value = "Playing";
//alert('playing');
break;

// Other cases go here.

default:
//alert('def');
//myText.value = "";
}
</script>
