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

You need to use a literal if you want to insert HTML and not have the code convert it into visible text.

This is plain english. It means what it says. Services like babel fish will translate it into whatever language you prefer, or, if you don't speak English well enough to understand this, then I'm sure there's a visual studio version in a language you would prefer.
I can't explain it any clearer than what the error message says. If you can't understand the error message, you won't understand my reply, as it will also be in English.

I created a web app in ASP.NET via Visual Studio 2008. I then uploaded it to my web hosting dir. But the app won't work as there is a config error trying to load System.Web.Extensions. OK, from what I can gather, there are 2 assemblies that need to be loaded, so I uploaded them to the web hosting dir, and instructed the web hoster to restart the server. But it still won't work, and the web hoster is saying that it is my fault.
Anyway, aside from fixing this error, doesn't it seem that a web hoster that claims to be able to host an ASP.NET application should be able to handle a "Hello World" web app produced by the latest Visual Studio? If there are any issues, shouldn't the web hoster be aware of them (especially after I have pointed it out)?

Depends on the web host and their setup. Some may well be hosting 2.0 and not 3.5.

System.Web.Extensions needs ASPNET Ajax installed. .NET 3.5 has it already. It is loaded in GAC with strong key. Check if you are using Public Token for it(I guess it is ) in your web.config.
I think you should install .NET 3.5 to the server before you could use it. If you are having Public token, you cant paste it to the bin directory and make it working.

I'm trying to use Response.TransmitFile in ASP.NET 2.0 instead of reading and writing chunks to a buffer for large files.
The questions I want to ask are:
1. Does anyone know how efficient Response.TransmitFile is? I can see that it doesn't add up the memory usage to IIS at all, but I'm not sure the impact on the server itself compared with reading and writing to a buffer in chunks.
2. What about security? by using Response.TransmitFile
Thanks,

AFAIK, Response.TransmitFile directly writes the file in the Response stream, which is similar to reading and writing chunks to a buffer. It flushes the buffer once the file is written to the output stream.
amarnath n.n wrote: 2. What about security? by using Response.TransmitFile
There is no relation of Security with this. Its actually reading the file from a specified physical location of the server and writes the file directly to the stream. If asp.net user has permission to that folder, it can transmit the file properly.

I never had to use Response.TransmitFile. IMO, simple method to transmit files is to redirect to the file name. Rest all will be automatically taken care.

You are assuming that the file is in the folder structure. Many, store files out of the folder structure of the website so they can be properly secured on a user to user basis.

Hello,
I have created a web user control and that contain a javascript method that check for required field. if there is a required filed not filled it return an alert. the problem is that the page post back not in the control pageload but the page that contain that control. how can i prevent from post back when a special field is required.
regards.

To call a javascript function prior to postback, take the button out of the form. Use the button to call javascript, and if everything is ok, use the javascript to call form.submit().

use
onclick = "return yourfunction()"
Now from the function return false when you show the alert, the page will then not be posted back. 
function yourfunction()
{
if ...
{
alert('invalid');
return false;
}
return true;
}
