How to get live stream from webcam in our web page?
|
|
|

You can't do that with ASP.NET. You can do it with HTML. What have you tried ? Did you search the web for info at all ? Where is the webcam, on the server ? You can create a stream and set up windows media player to display it.

AFAIK, live stream can only be captured using some windows client...
or any plugin which allows direct access to webcam devices.
I dont know if Flash / Adobe AIR / Silverlight plugins allows you to capture live streams from browser. If they cant, you need to create your own browser plugin.

This was my code to display live streaming from webcam.
hope thi will work for u.
u need to install the webcam and than place this file in ur initpub folder
to share the images on web and allow the user to view it.
u also need to install latest version of media player and windows media encoder.
<object id="MediaPlayer" width="176" height="144" classid="CLSID:22D6f312-B0F6-11D0-94AB-0080C74C7E95" standby="Loading Windows Media Player components..." type="application/x-oleobject" codebase="http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=6,4,7,1112">
<param name="autoStart" value="True" />
<param name="filename" value="http://localhost:8080" />
<param name="ShowControls" value="False" />
<param name="ShowStatusBar" value="true" />
<embed type="application/x-mplayer2" src="http://localhost:8080" name="MediaPlayer" width="176" height="144" autostart="1" showcontrols="0" />
<object id="Player" width="300" height="250"
classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6">
<param name="URL" value="http://localhost:8080" />
<param name="uiMode" value="none" />
You can also view this live feed directly in Windows Media Player by clicking here.
and do not forget to rank the reply if u get thi working....
all the best

TextBox1.Text = "" 'Didnt work the textbox is holding the last value
i also tried this in the [Page_Load]:

You might be setting it up on page_load :S

Have you stepped through the debugger ? If you're using a third party control, perhaps it is what sets the value ?

That won't work. Perhaps if you used the right client side ID, it might.

And also before you run a script check if the script block is already exists in the page.Do like this :
if(!this.ClientScript.IsClientScriptBlockRegistered("MyScript"))
{
Page.RegisterClientScriptBlock("MyScript","<script language=javascript>" & _
" document.getElementByID('" + TextBox1.ClientId +"').value = '' ; </script>")
}
Also make sure you are not doing this every time the page is posted back. Always check :
if(this.IsPostBack)
{
}
inside Page_Load
Finally, if you make TextBox as serverside, you can set the value inside ddlVacationTypes_SelectedIndexChanged by just calling
TextBox1.Text = ddlVacationTypes.SelectedValue
It must work.

Unfortunately it did'nt work ,i do want this every time the page is posted back , i mean when the user select from the DDL the textbox1 should be empty for him(user) to notice and select a date from the Obout calender image , i tried it both ways(if and if not is post back) it didnt work , i found this property Clear() on the Obout tutorials :
**************************************************
If you need to clear the current selected date simply call the method Clear.
Example:
<obout:Calendar runat="server" id="myCal">
</obout:Calendar>
<a onclick="myCal.Clear();">
Clear
</a>
***********************************************
by the way ive two page loads
one page_load in the user control where the DDl and obout Calender and of course its Textbox which we want to clear
Second page_load in the actual default page
so ive tried to use that property in both page_loads it didnt work ,i have follwed the debugger it going in the right way , here is the code
-----------------------------
Dim script As New StringBuilder
' Dim reader As StreamReader = File.OpenText(Server.MapPath(includeFilePath))
If Not Page.ClientScript.IsClientScriptBlockRegistered("MySript") Then
'script.Append(reader.ReadToEnd.Replace("{title}", Me.Title).Replace("{buttonLabel}", Me.ButtonLabel))
' delay alert 1 ms to handle postback
script.Append("<script language='javascript'>document.dfghsdfggetElementByID('Calendar1').Clear();</script>")
Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "MySript", script.ToString)
End If
--------------------------------------------------------------------
one more thing the server doesnt seem to validate what inside the script even if write
Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "MySript","Nothing")
what is a problem? + how to fix it?

Hi,
We have .Net Framework 1.1 and 2.0 installed on the same server. We now have new requirements that will need AJAX. We can either install:
1. .Net Framework 3.5
OR
2. AJAX Toolkit (with existing .Net Framework 2.0)
We do not want to have any issues with existing applications due to this. Please suggest which will be a better approach and what will be the impact on existing applications using older versions?
Are there any specific guidelines for having multiple versions on same server?
Regards,

You don't need to install anything, unless what you mean is, we don't know enough to use AJAX and will need to use a Microsoft framework instead. AJAX is nothing to do with ASP.NET, only the Microsoft wrapper library is.

column in gridview having checkboxes ,when i check one of the checkbox , gridview disappear .
I have bind my gridview in
if(!ispostback)
{
}
the datatype of column in datasource is TINYINT(1) that is converted to checkbox column.these checkbox
were disabled ,i enabled these in rowdataboundevent of gridview to get user feed back

If you don't bind on postback then I'd be checking to make sure that the viewstate is not turned off for the page.
