I am working with ASP.NET 2.0 and VS 2005 to implement a new functionality.The functionality is to simply warn the user through a popup window before a predefined time that Session is about to timout.The user has two choices, either to ignore the warning or to renew the Authentication.
I am creating FormsAuthenticationTicket to define the timeout interval as displayed below:
<br />
Protected Sub Login1_Authenticate(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.AuthenticateEventArgs) Handles Login1.Authenticate<br />
If Membership.ValidateUser(Login1.UserName, Login1.Password) Then<br />
Dim oTimeout As Integer = (Convert.ToInt32(ConfigurationManager.AppSettings("TotalTimeOut")) / 60)<br />
Dim ticket As FormsAuthenticationTicket = New FormsAuthenticationTicket(1, _<br />
Login1.UserName, _<br />
DateTime.Now, _<br />
Date.Now.AddMinutes(oTimeout), _<br />
Login1.RememberMeSet(), _<br />
"", _<br />
FormsAuthentication.FormsCookiePath)<br />
<br />
' Encrypt the ticket.<br />
Dim encTicket As String = FormsAuthentication.Encrypt(ticket)<br />
<br />
' Create the cookie.<br />
Response.Cookies.Add(New HttpCookie(FormsAuthentication.FormsCookieName, encTicket))<br />
<br />
' Redirect back to original URL.<br />
Response.Redirect(FormsAuthentication.GetRedirectUrl(Login1.UserName, Login1.RememberMeSet()))<br />
<br />
<br />
End If<br />
End Sub<br />
I am displaying the Warning by using Page.IsClientScriptBlockRegistered to register a Javascript function that is called with windows.setinterval.
The problem I am facing is how to renew the Authentication.I tried to update the cookie expire date and it back to the cookiecollection but that didnt work:
<br />
authCookie As HttpCookie = Request.Cookies(FormsAuthentication.FormsCookieName)<br />
authCookie.Expires = DateTime.Now.AddMinutes(oTimeout)<br />
I've also tried to signout the user (FormsAuthentication.Signout) and recreate a new ticket and that didnt work either.
I really appreciate any help.

hi,
im developing a website in ASP.NET can anyone tell me how to import the swish file into ASP.NET code?

I have a web application that access SQL Server for all of it's data. It authenticates to SQL with a trusted connection using a special domain account that the web server is running under. The application uses impersonation to know who is doing stuff in the application. Everything stated above works fine.
I have since added a Web Service to the same application as a "backdoor" to get data from the database. When I invoke a method on the service, I get a general access denied like exception. The exception is often pointing to some random DLL in the ASP.NET temporary files. Through research on the internet, I have narrowed this problem to being some sort of "web service cannot access SQL" problem. I am just confused as to why the web forms part works fine but the service does not. It is worth noting that I am passing the credentials to the web service and that the web server resides on a different server than SQL
Thanks.

I have noticed that content file is used when we talk about asp .net code, and code-behind file when we talk about c# code.
but I don't understand what these two statments are actualy mean !

Code-Behind is a seperate file containing your VB/C# Code. This is held seperate from the ASP code.
ASP use to be code and html content all in one but .Net has chaned this...
I am very new to these concepts but found code behind is a great logical split from the ASP and the VB/C# code.
Hope this helps....

I am pretty new to asp.net and I am teaching myself through books and other materials. I am having a problem that I don't know how to handle this. Here is my example. I want my users to be logged in to view certain content of my site. If the user clicks on a link without being logged on I want user to be redirected to my login.aspx and after the user logs in be directed to the link that they clicked on? Any have any sample code of how this works?

Hi,
cisco2103 wrote: I want my users to be logged in to view certain content of my site.
Step 1 : You can create a Session for each user.

All the links where you want to check whether a user is logged on or not, check the session already created in "Step 1". For this, you can create a common page which accepts a query string of a target link. All of your links will point to this page. This page will check whether an user is logged in or not. If yes it will redirect to the target link from the query string, else to the log in page.
The log in page will also accept a query string, denoting where the user should be redirected. When user logs in successfully, the ok button will redirect the user to the source from where session was expired or user tried to access without logging in.
Hope i am clear enough. As far as syntactical part, you can always get help on msdn library.

OK let me clarify and make sure I understand what you are saying. Instead of using a cookie I would be using a sessionid for each user. A sessionid is pretty much the same as a cookie except it expires when it leaves IE? For step I am following you some. SO on a pageload event for a click link or button I would have something like.
if sessionid.value is nothing
response.redirect("login.aspx")
endif
I am very confused on the second part of step two. Code Examples would be very helpful if you have any.
Thanks Terry

Don't be confused. This solution isn't worth pursuing when you have all of the plumbing provided by ASP.NET framework.

All that you are asking to do is built in to APS.NET. Using the web.config file you set the security for the folders, granting or denying access to users or groups. When someone attempts to access a file within any of these folders the ASP.NET framework will redirect them to a login page (provided you have specified one) then redirect them on to the original link after they have sucessfully logged in.

Hi! I'm verry new to asp.net, but i've worked before with C# and it's quite easy learning. one of the things i don't know is how to acces the data in App_Data folder. i have an .xml file i want to load into a dataset. the website works on localhost when i have the path set as "c:\\Project Data\\Denumiri.xml", another folder where i have my files. Still, i want to include the .xml files in the project and access them.
<br />
ds_Denumiri1.ReadXml("\App_Data\Denumiri.xml", XmlReadMode.ReadSchema);<br />
Thanks a lot for your answer!

The ReadXml method is not specific for the web, so it doesn't use a logical path.
Use Server.MapPath("~/App_Data/Denumiri.xml") to get the physical path to the file.

THANKS A LOT!!
it was useful... i compiled it and it works on localhost. still, i get an error when i try to run it remotely, on http://drcnoib.somee.com[^] . i've set the customerror mode="Off" in web.config, but i still get that error.
i think the error comes from page_load event:
<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
<br />
if (!Page.IsPostBack)<br />
{<br />
<br />
ds_Denumiri1.ReadXml(Server.MapPath("~/App_Data/Denumiri.xml"), XmlReadMode.ReadSchema);<br />
ds_Denumiri2.ReadXml(Server.MapPath("~/App_Data/Denumiri.xml"), XmlReadMode.ReadSchema);<br />
<br />
DropDownList1.DataSource = ds_Denumiri1.Tables[0]; <br />
DropDownList2.DataSource = ds_Denumiri2.Tables[0]; <br />
DropDownList1.DataTextField = ds_Denumiri1.Tables[0].Columns["Statie_Nume"].ToString();<br />
DropDownList2.DataTextField = ds_Denumiri2.Tables[0].Columns["Statie_Nume"].ToString();<br />
DropDownList1.DataValueField = ds_Denumiri1.Tables[0].Columns["StatieID"].ToString();<br />
DropDownList2.DataValueField = ds_Denumiri2.Tables[0].Columns["StatieID"].ToString();<br />
DropDownList1.DataBind();<br />
DropDownList2.DataBind();<br />
}<br />
<br />
}<br />
but i don't know how to find out which is the error or when it occurs.   . thanks a lot, anyway.

Hello
Upload new modules
i) Each module consist of ascx (asp/net user controls) & programming script and database script – modules can be any programming/database (PHP/mySQL or ASP/mySQL or ASP/Access or PHP/Access or Asp.net/MS SQL etc etc ) – every time a new module is added the super admin can specify the programming and or database
(1) Admin should be able:
(a) to upload ascx controls for backend administration and PHP User Modules with database script file
(b) Publish Modules to all accounts or to select accounts only
Comment:- This Project is basically a CMS System. By using my application user can make his own site.In my specification there are certain PHP module which will be developed by the PHP Developer and I have to integrate these module with my Asp.Net Application.So user can directly use them into his own site.Not getting what to do with point.
Plz Guide me..
thanx
