you might want to take a look at Silverlight. I remember seeing a demo at the Remix convention about several video clips being play simulatenously on a webpage. Go to http://www.silverlight.net

Edit:
Here is a tutorial which explains how to use Silverlight and streaming videos via webpage
http://aspalliance.com/1342_Streaming_a_Silverlight_Media_Application_from_Silverlight_Live#Page5

In particular go to the section titled " Invoke multiple video files from a single web page" which is the answer you are seeking.

Silverlight rocks when it comes to media streaming.

It doesn't expose properties that you can natively hook into through C#. The properties are all controlled through HTML using the PARAMS and EMBED tag on the object. Here's an example:

<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" WIDTH="550" HEIGHT="400" id="superflashMovie"><PARAM NAME=movie VALUE="superflashMovie.swf"><PARAM NAME=quality VALUE=high><PARAM NAME=bgcolor VALUE=#FFFFFF><EMBED src="/support/flash/ts/documents/superflashMovie.swf" quality=high bgcolor=#FFFFFF WIDTH="500" HEIGHT="350" NAME="superFlashMovie" TYPE="application/x-shockwave-flash"
PLUGINSPAGE="http://www.macromedia.com/go/getflashplayer"></EMBED></OBJECT>

Well, the only way that I can think (off the top of my head) to do this would be to use javascript to play the next movie in a sequence after a period of time. Assume that you've given the Flash object an id of "mySecondMovie", you could do this to trigger the movie:

<SCRIPT LANGUAGE = "JavaScript">
<!--
var secs
var id = null
var isTimerRunning = false
var delay = 1000 // 1 second

function InitializeTimer()
{
    // Set the length of the timer, in seconds
    secs = 15 // The length of the first movie in seconds.
    StopTimer()
    StartTimer()
}

function StopTimer()
{
    if(isTimerRunning)
        clearTimeout(id)
    isTimerRunning = false
}

function StartTimer()
{
    if (secs==0)
    {
        StopTimer()
        playMySecondMovie()
    }
    else
    {
        self.status = secs
        secs = secs - 1
        isTimerRunning = true
        id = self.setTimeout("StartTimer()", delay)
    }
}

function playMySecondMovie()
{
  if (document.mySecondMovie)
  {
    if (document.mySecondMovie.Play)
      document.mySecondMovie.Play();
  }
}
//-->
</SCRIPT>

Then, in your body onload, you would call InitializeTimer.

Thanks for it. but how can i calculate the length of the first movie. Is there any event occures at the end of Video clip? so that I can check it?

Not that I'm aware of. Mind you, if you have the flash itself, you could always call the javascript to play the next movie using an ActionScript command:

getUrl("javascript:playNextPage();")

Then, you would implement the playNextPage javascript in your page to play the next movie as outlined above.

Mark the object with runat="server".

Sorry but it didn't worked. I'll show u my code.

<%@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="false" Inherits="Video.WebForm1" %>

<title>WebForm1

<object id="Player" runat="server" width="425" height="350" viewastext=""><param name="movie" value="http://www.youtube.com/v/5Uahw5BU9N8" /><param name="wmode" value="transparent" /><embed src="http://www.youtube.com/v/5Uahw5BU9N8" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350" />

Now, Player is the object id of object i hav created in Html tags. I want this object to be accessed in Code behind, like Textbox or Label or Button etc objects can be accessed there.

Image Processing on WinCE

I'm not sure what you are trying to achieve here - the flash is a clientside object. What exactly do you hope to achieve?

Hi,

Im hoping someone here can help...

I am involved in a project that needs to perform some image analysis on an image to interpret results. The functions I need are as follows: scaling image, image rotation and finally analysis at a pixel level. We are running on WinCE and coding with C#. I am able to find good image processing libraries for WinXP which unfortunately don't work on WinCE due to the cut down functionality in Compact Framework 2.0.

I haven't been able to find a WinCE compliant libraries. Maybe someone here knows of one? Any other suggestions? Or is my best bet writing something myself? I see a few posts on accessing pixels and image manipulation using unsafe methods.

Hoping for some leads...
Thanks.

Regards,
Myron

If you have access to unsafe code, try my image processing code as a starting point. If not, then you're stuck with the getpixel method, which is slower.

Hi..
Im using IFrame as my body in my aspx page to generate Emails. To edit IFrame i just wrote the following code in Javascript..

IFrame1.document.designMode="On";

After this line is executed the Iframe is editable and i can type any text inside iframe.
Now Im using VBScript to create a word application as an object for spell checking. In this case I need to pass the Text of the iframe as a parameter value to VBScript funtion i wrote.
The issue is i cant get the Value or text inside the IFrame using VBScript.
i wrote the above code in VBScript Function but it is not getting the text inside the iframe.

set Ctrl = document.getElementById("IFrame1")
MsgBox(Ctrl.innerText)

How to get the value or innertext of the iframe using vbscript or the other way is how can i create a word as an object and using that object how can i spell check in Javascript?
pl. help me in this issue. im working for this for the past 1 week. its urgent.
Thanks in advance

Return type

Hi,
Can anyone tell me wat will be the return type if i am returning a interface?
i.e. My code has a function which has to return an interface..so wat should be my return type for that function.

Thanx,

SRUJANA

I don't get the question. If you need to return an interface, then that interface is the return type. So, if you want to return an IDisposable, then IDisposable is your return type.

You can return an object which impelement interface.

The return type will be your interface, as already said. The underlying object should be one that implements your interface, directly or indirectly.
