Hello,
I have developed an app that allows users to upload asp files to a webserver, and would like to have them play dynamically. Does anyone have any suggestions as to how to make this happen? I have tried ASPNet Audio and PseudoMP3, but neither work.

Well, odds are very good that they work and you just can't work out how to use them.
There is no way ASP.NET can play an mp3. you need an activeX, java or other plugin to do that. So, you need to choose a plugin, and stick with it until you can work out how it works, perhaps asking for help on the forums of the people who provide it.

Hi All,
I have an asp ImageButton within a gridview. Normally, I click the button, and the row upon which the button is in, is deleted.
It worked well for a long time, until one day it didn't.
I have spend exactly 12 hours now trying to work out what has happened, and I have found the problem.... I just don't know how to solve it.
The problem comes from me having added a custom control to the page.
I registered the control like this:
<%@ Register TagPrefix="user" TagName="AddressForm" Src="UserControl/AddressForm.ascx" %>
The control is pulled into the page like this:
<fieldset style="margin-left:10px;margin-right:10px">
<div class="cart_spacer"></div>
<legend><span style="color:#c90101;font-size:12px; font-family: Arial, Helvetica, sans-serif">Shipping Address</span></legend>
<div style="padding:5px 5px 5px 5px" class="productSubHeading">
Enter the address where you would normally want your order shipped. <br /><i class="cart_small">(this can be changed whenever you place an order)</i>
</div>
<div class="cart_spacer"></div>
<user:AddressForm
id="shippingAddress"
ShowCopyCheckBox="False"
CopyCheckBoxText=""
Runat="server" />
</fieldset>
The Gridview looks like this:
<asp:GridView ID="grd_Cart" runat="server"
AutoGenerateColumns="False" Width="100%"
OnRowDataBound="grdCart_RowDataBound"
DataKeyNames="TempDetId"
DataSourceID="sqlGrdCart"
GridLines="None"
BorderColor="#CCCCCC"
BorderWidth="1px"
BorderStyle="Solid"
AlternatingRowStyle-BackColor="#F2F2F2"

So can anyone tell me why my imagebutton won't fire any code event when this user:AddressForm is on the page? If i remove it from the page but leave the register block in there, it all works fine.
Apologises for posting so much code, I am anticipating that you'll need to see it.

Put your update panel outside your grid, see if that works. Had similar problem when i used update panel inside a grid.

Thanks for the info, but I've tried that already during the elimination process.
Besides, the msdn docs show what I've done as an example with Update panels.
http://msdn.microsoft.com/en-us/library/system.web.ui.updatepanel.aspx
Prior to this problem, I had the whole Grid in an update panel, because I didn't realise you could put an UPan in an item template.
The problem is definately associated with this custom control... if I remove the control, everything works nicely.

Does this runs? The update panel does not contains any control with ID "butPostBack".
It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

yes the button is located elseewhere on the page and is called from js to fire a partial page postback.

You have to put it inside Table.

We are planning to do a twitter like social networking application.Is there any sample code that we can refer for creating micro blogging application like twitter?
|

How much have you done up to now? If you need to ask a question like this you are probably working on the wrong project.

You better ask twitter to get your answer. 
Anyway, it's upto you how you want to have your architecture. Try out with simple .NET application with multiple users. Then see how much you want to scale up...Anyway, best of luck...

Hi. Im generating half my page with normal html and half from the code behind.
<normalhtmlstuff>
<p id=<asp:label>>
</normallhtmlstuff>
Ok, you can get the idea of what i need. Problem is that when doing it like that and changing the labels to something it comes out like id=<pre>"myid"<pre> or something to that effect.
Thanks
