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.

Should a web hoster be able to run an ASP.NET web app created by VS 2008?

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. Frown | :(

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:

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.

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. Smile | :)

function yourfunction()
{
 if ...
 {
   alert('invalid');
   return false;
 }
 return true;
}

How to get logged on user (Windows Authen/Active Direct)

Shameegh Boer11-Sep-09 4:26

Hi.

Hoping you guys can help me, and more importantly, the message I'm typing actually conveys my problem. I've come across a few forums where guys having my same problem, being answered in the way we don't want to.

My intranet website currently uses session variables and cookies to authenticate user. I would like to use the Active Directory login details of the user to gain access to the intranet. Now, to gain access to a PC, a user needs to login using his AD un and pwd, so surely the logged on user should be known somewhere.

So instead of using sessions and cookies, I want the user currently logged details, and directly log on to my intranet website. So I don't need to prompt the user again for details.

I think a step in the right direction would be to at least get the logged on user.

System.DirectoryServices DirectoryEntry and -Searcher doesn't really get you the logged on user. You can use these to search and add entries, but ya, they still don't provide me with the currently logged on user.

Going to IIS and Disabling anonymous access, and setting Integrated security. Kinda helps, but then my users still get prompted for a username and password. And yaaa, once again, I don't want that pop-up, because the user already needed to logon to the PC using his/her AD details, why can't IIS just use that.

And Lastly.

WindowsPricipal and Context.User.Identity.Name.... well, they only get set once the user logs in on that IIS popup I mentioned early, or simply not display anything when anonymous access is allowed.

I guess a short version is...
How do I plug my intranet into my active directory, without prompting the user for details again.

Hope my problem is stated clearly.

Thanks

Is your client, web server, and active directory server all on the same domain (or at least trusted among multiple domains)? This is a must in order to get authentication to work seamlessly.

Try this for getting currently logged user name..

private string GetCurrentLoggedUser()
{
return System.Environment.UserName.ToString();
}

System.Environment.UserName - It return the logged user on the target OS.
