That is bogus. Where did you get that information from? asp.net never runs under Network Service account. It runs under ASPNET build in account. ^

Hi Yusuf,
Please read what i had mentioned in my reply. I said asp.net application will run under Network Service account in IIS6.0. IIS 6.0 is used in Windows 2003 and IIS 5.x is used in Windows XP. Usually the asp.net runs under aspnet account in Windows XP.
The question is related to some issue in the server not in the PC. Therefore please read again the MS Technet link carefully.

How do you get the System.Web.HttpContext.Current.Request.ServerVariables("HTTP_REFERER") in a web service. I need to know where the request is coming from and using the above does not work.

Thanks

Isn't HTTP_REFERER a HTTP Header and not a Variable?

System.Web.HttpContext.Current.Request.Headers

Don't bother with server variables or headers. Just use the Request.UrlReferrer[^] property directly.

Datalist: Display page

I have a datalist having a dropdownlist control on each row. On selecting a particular item of this dropdown, I need to display a page in that particular row of the datalist. There are five different pages and the selection of the page to be displayed depends on the item selected in the drop down list.

Actually, the controls on the pages is waht i need. So instead of the pages if you have any other option do let me know.

Note : The number of rows in the datalist keeps on varying.

Hi guys,
I am new to ASP.net and I am trying to achieve the following:
I have created a login page where I want only 1 user logged in at any period. Is there a way to get the current # of user logged in, in ASP.Net?

Basically, when second user tries to login, I want to check if there is another user logged in. I tried using session but that doesn't work because each user is on a different computer browsing the site.

Please help!!!!

what do you meant only 1 use logged in at any time? I hope you not restricting Only ONE user to connect to your application at a time. If that is what you want, you are in the wrong place. Web app are meant to be used by multiple users at a time.

If you want to limit to a single login to each user, then you need to track who is logged in. When a user logs in then flag that in your users table. Then when the user logs out, remove the flag. Then you need to handle end of session event and remove the flag for that user. When you notice a user tries to log in multiple times, then you can redirect them to different page (may be user already logged in message)

Hi Yusuf,
Yes I want to only allow one user at a time on the webpage considering the sensitive information processing the page does. Are you saying I should use Session_Start and Session_end? If so, pardon my ignorance but how do I implement these functions?

Yusuf,
I know that is what I need to do but my question is how do I go about doing that. If I am updating the database then how do I know that the user has not just closed the webpage instead of loging out.

Do you know what I mean?

I don't know your level of asp.net competency, but your question is a bit silly

- Session_End signals the session is expiring, has nothing to do with user logging out or browser closing

- Browser Closing - There is no way you can detect this from the server. You can write some js to detect browser closing ( mind you there is no browser support for this, all is behind the door hack)

- user logout - the user clicked on logout, so you know that, don't you, don't you....

xml

Hi,

I have created a string using StringBuilder class. This string is an xml.
Now my question is that how do i pass this string to xmlTextWriter or XmlDocument class to get the correct format of the string ?

I don't want to start creating the xml using XmlDocument class or XmlTextWriter as it's really cumbersome to nest the xml in it. It's all done using StringBuilder and now i just have to correct the format of the string..

Any idea ??

Thank You
Andyy

XmlDocument has a method LoadXml that takes a string.

What are you trying to do exactly? I thought perhaps you were trying to validate the xml, in which case you could by trying to load it.

basically xml is stored as a string using StringBuilder which ends up with non xml format and hard to read. So one way is that i fix the format manually which is again a pain. So i am asking if there is any second way which can correct the format of the string as xml.

I hope it's clear now.
