null string returned for domain and username (Windows auth)

I'm trying to capture the username (and domain) of the user accessing the web application (web server on the same domain for starters). I have modifed the IIS settings to use Windows authentication and added stuff to web.config and use the following code below to capture this information - and it works as long as the web server is the localhost i.e it works only if the web app is accessed via a browser on the web server. Otherwise it returns a null string, what do I need to do? (currently buidling on .NET 2.0)

Snippet of code in VB.NET (objGenericIdentity.Name contains null string when web app is accessed outside of web server):

Dim formsAuthTicket As FormsAuthenticationTicket
Dim httpCook As HttpCookie
Dim objGenericIdentity As GenericIdentity
Dim objMyAppPrincipal As securityPrincipal
Dim strRoles As String()
httpCook = Context.Request.Cookies.Get("authCookie")
formsAuthTicket = FormsAuthentication.Decrypt(httpCook.Value)
objGenericIdentity = New GenericIdentity(formsAuthTicket.Name)
strRoles = formsAuthTicket.UserData.Split("|")
objMyAppPrincipal = New securityPrincipal(objGenericIdentity, strRoles)
HttpContext.Current.User = objMyAppPrincipal

web.config contains this:
authentication mode="Windows"
identity impersonate="true"

(I'm not using anything related to formsauthentication in the web.config file, do I need to?).

And finally, what would I need to do to get this info when web app is accessed from a different domain?

If you are using .Net 4.0 framework then you can use inbuilt Web Form routing:

ASP.NET Auto-logout

For an ASP C# website I made, I have user authentication using the Membership framework with SQL Server as the back end. The only complaint so far is that after a certain amount of time, they get automatically logged out. Is there anything I can do to make sure that users will stay permanently logged in unless they manually logout?

Edit: The webserver is IIS 7.5. I suppose this could just as easily be an IIS question.

The default timeout for session is 20 minutes. If the user takes no action, i.e. refreshing the page or navigating to another one, the server can't tell if they closed their browser, gone somewhere else, or died. You can adjust the timeout via the web.config file but you will still be left with the same problem, just at a later time

I figure setting it to 122 years and 164 days should be sufficient. Smile | :)

Legacy ASP, or ASP.Net? You have to find a 3rd-party library to do what you want.

I actually did just that at one point. I found that the free libraries were crap (didn't render the page as expected). The way I got around it was to use a Windows Forms WebBrowser to render the page (on the server side), render that control to a bitmap (WebBrowser.DrawToBitmap), save that bitmap as a PNG, embed that PNG into a PDF (the free libraries seem to be capable of at least this), then return that PNG to the browser as raw byte data (this will help you figure that out). I also remember having to do some custom HTML parsing to print each page neatly. It's tricky, but can be done (took me 2-4 days IIRC). Google for anything above you don't know how to do (e.g., you can google for free PDF libraries).

Hi All, I am wondering how to validate date using regular expression and not allowing any future date if the user wants to put it in anyway.
thanks,

Hi,
no, it's not possible with regular expression, regular expression can only validate patterns, you can use compare validator for this purpose or use .NET function DateTime.Now to acquire todays date, then compare it programmatically with the date from user's input.
Regular expression for date is
(?x)(? Blush | :O

[1-9]|1[0-2])(/?)(? Blush | :O

[1-9]|[12][0-9]|3[01])(\1)\d{4}\d/\d/\d{4}

Thank you Iqbal bhi, I will get the user input and then compare with present date in the back end.
thanks for the date format.

thanks for your reply, I know it can be done using back end Csharp code. But how do I display message to user that something is wrong.

Just to add to Shahriar Iqbal Chowdhury's answer, you can use the regex validator to do an "idiot check" Client side and use dateTime.TryParse[^] to check server side. There are several attempts to do it here[^] without the regex using JavaScript instead.

For the regex pattern, I've always found http://regexlib.com[^] useful, it also gives a summary of how well well the regex matches etc.
