how to set a specific path (e.g. apppath or d:/myfolder) to all session objects across my ASP.NET 2.0 (state server configured) application so that all sessions will save/store in myfolder only.
View 4 RepliesI would like to check if someone tries to access the application with the same username from a different browser/pc/etc. All usernames and passwords are stored in a MSSQL db.
What I am doing at the moment is: In the global.asax-file in Application_start(..) I initialize [Code]....
Now with every user that logs in I can check whether he is allready in ( in that case, he won't be able to log in, he'll be redirected to the login page ). Let's say it's the same user who wants to login but for some reason he wants to start the application from a different pc, maybe in a different building. Unless he hasn't forget to logout, he won't be able to login on this different computer. So he would has to go back and logout or wait for the timeout.
Now wouldn't it be more convenient to abandon the first session and let the same user login to the pc where he is right now?
The question is, is it possible to end the first session without beeing in it? Or is there any other solution for that problem? Since I have the SessionID stored in Application["UserList"] is there any possibility to end that specific session?
I am trying to figure out how to associate a specific user to a specific data on the site, like social networking site.
View 3 RepliesI had a problem in site map path I had navigation bar which take from sit map path but I want site map path tack value from page as product also how can i remove underline in site map path
this my site map path:

ForeColor="White">
<PathSeparatorStyle ForeColor="White" />
<NodeStyle ForeColor="White" />
<RootNodeStyle ForeColor="White" />

Most succinctly, my question is whether an ASP.NET 4.0 app running under IIS 7 integrated mode should be able to honor this portion of my Web.config file:
<location path="auth/windows">
<system.webServer>
<modules>
<remove name="FormsAuthentication"/>
</modules>
</system.webServer>
</location>
I'm experimenting with mixed mode authentication (Windows and Forms - I know there are other questions on S.O. about the topic). Using IIS Manager, I've disabled Anonymous authentication to auth/windows/winauth.aspx, which is within the location path above. I have Failed Request Tracing set up to trace various HTTP status codes, including 302s.
When I request the winauth.aspx page, a 302 HTTP status code is returned. If I look at the request trace, I can see that a 401 (unauthorized) was originally generated by the AnonymousAuthenticationModule. However, the FormsAuthenticationModule converts that to a 302, which is what the browser sees. So it seems as though my attempt to remove that module from the pipeline for pages in that path isn't working. But I'm not seeing any complaints anywhere (event viewer, yellow pages of death, etc.) that would indicate it's an invalid configuration. I want the 401 returned to the browser, which presumably would include an appropriate WWW-Authenticate header.
A few other points: a) I do have <authentication mode="Forms"> in my Web.config, and that is what the 302 redirects to; b) I got the "name" of the module I'm trying to remove from the inetservconfigapplicationHost.config file; c) I have this element in my Web.config file: <modules runAllManagedModulesForAllRequests="false">.
how to upload image on to server having specified path name. and for each time the image path need to change.

In the VS2005 environment, when I test my session to make sure the page redirects to the main page (itself) if the session is null, it works. There is no error.
The function I use for this is:
[code]....
However, when it is in the production environment in IIS 6.0, when the session has timed out, and I then do a postback by doing some slider control, I see the page reload but immediately thereafter, it throws a Server Error exception of : Object reference not set to an instance of object.
Looking at the stack trace, the event occured:
AJAXEnabledWebApplication1._Default.Slider1_TextChanged(Object sender, EventArgs e)
however, why is it that the Slider1_TextChanged event fired even even after during page_load, the page was told to do a response.direct ?? shouldn't the entire page have gone through a full-page refresh life cycle ? why did it continue on to attempt to raise the Slider1_TextChanged event?
I am getting object refernce error at line:if (Session["Tax"].ToString() == "9")
protected void Page_Load(object sender, EventArgs e)
{
if (Session["Tax"].ToString() == "9")
{
lblTax.Text = Session["Tax"].ToString();
}
else
{
lblTax.Text = "0";
}
}
Is anything wrong I have done?
I am confused about how to reference objects in session, how to update, and copy.
if I create
MyObject obj = new Object ();
then
Session["object"] = obj;
MyObject temp = (MyObject)Session["object"];
If i change something on temp, will the object in session be updated? do i need to follow changes with Session["object"] = temp?
I want to be able to persist data across a session but do this outside of the built-in session state object. Why is a long story that I will not go into here. I just need to know where I can put data other than in the session object that will persist across the specific session.

I have an application that has a user Login Control (provided by ASP). I am just now working with the integration of a dataBase created in MS visual studio 2010, to a developed website created in MS visual web developer 2010. My main goal is to create an authentication ticket that enables a user to be able to see a dataBase information only after that user has been successfully authenticated.
Up to now I'm able to see the dataBase when i run the website even if I'm not log-in, how i can create a home page that tells the user to log-in and once that user has successfully log-in it redirects the user to another page where the user can see the database and how I can add information to that dataBase only to specific members
I have a list of Controls that are held in a List<Control> and I want to be able to check their type. As my list holds only Controls, doing typeof() isn't going to get me too far, I want to be able to ask if List<Control>[0] is a Checkbox, TextBox, Label, etc.How do I go about finding out what specific type of Control I have in my list?
View 7 RepliesI'm pulling all the objects from an entity in my database
Dim dbConfig as New housingEntities
Dim update_query = (From p in dbConfig.Configs _
Select p)
Then, I want to individually access the rows and perform updates to them...For example, if I just needed the first row I could go like this:
update_query.First.timeValue = txtFRRSD.Text
dbConfig.SubmitChanges()
Now, I don't know how to code this, but here is pseudo what I'd like to do:
update_query.Item("FRRSD").timeValue = txtFRRSD.Text
update_query.Item("FRRCD").timeValue = txtFRRCD.Text
update_query.Item("SORSD").timeValue = txtSORSD.Text
update_query.Item("SORCD").timeValue = txtSORCD.Text
dbConfig.SubmitChanges()
Does anyone know a way to do this or something like this?

View 2 RepliesI'm using urlrewriting to rewrite my url. Let me introduce my problem by bellow example: Here is old url: http://localhost/test/pages.aspx?pageid=1 I have 2 cases to rewrite:
http://localhost/test/url-rewriting-get-start.aspx
http://localhost/test/url-rewriting/get-start.aspx
The first case is ok, but I would like to use the second case. In this case I must use root path for image, css and object tag (for flash):
With image, I modified to: <image src="~/images/icon.jpg" runat="server"/>
With css, I modified in head tag: <head runat="server">
But with the object tag, I don't know how to set root for the data, movie parameter:
<object data="anim/head.swf?xmlPath=./menu_flash.html" type="application/x-shockwave-flash" width="962" height="228">

How to get UserId and stores it in the table when I create a new user?
Anything I have tried didn't work. Currenly I have following code to change asp.net session cookie expiration date and path, but asp doesn't want to listen to me. I sends same cookie in Set-Cookie header two times sometimes, sometimes it sends it's default cookie ignoring path and expiration date, sometimes it sends everything as expected, and sometimes it doesn't send Set-Cookie at all. What should I do.
My code in Global.asax
protected void Application_PreRequestHandlerExecute(Object sender, EventArgs e)
{
/// only apply session cookie persistence to requests requiring session information
if (Context.Handler is IRequiresSessionState || Context.Handler is IReadOnlySessionState)
{
var sessionState = ConfigurationManager.GetSection("system.web/sessionState") as SessionStateSection;
var cookieName = sessionState != null && !string.IsNullOrEmpty(sessionState.CookieName)
? sessionState.CookieName
: "ASP.NET_SessionId";
var timeout = sessionState != null
? sessionState.Timeout
: TimeSpan.FromMinutes(20);
/// Ensure ASP.NET Session Cookies are accessible throughout the subdomains.
if (Request.Cookies[cookieName] != null && Session != null && Session.SessionID != null)
{
Response.Cookies[cookieName].Value = Session.SessionID;
Response.Cookies[cookieName].Path = Request.ApplicationPath;
Response.Cookies[cookieName].Expires = DateTime.Now.Add(timeout);
}
}
}
I want to terminate the session after specific time. So how can solve it.
View 3 RepliesI have an asp.net application with c# language. I have a common class which maintain the constants and static variables and fields. I also have a login page. If the user logs in successful I set IsLoggedInSuccessfull as a static boolean variable in common class.
My question is: Will this only work for a specific user session or for overall application ?
Edited:
Based on some answers I got another question here.
let say i am using the Static method as Authenticate(User objUser). intention is to call this method when user clicked log in button. where on login button I am let say prepare the User object with certain parameters required for login, then passing to this method. what would be the impact there? let say I have single server for now (no server farm or garden). then there will be the single application level method to authenticate the user, right? and say 10000 user are going to logging in to this site/application then how authenticate() method comes in behaves ? will CLR automatically manage threading there ?
I have a gridview with a nested placeholder in each rows. I nested some checkboxes in each placeholders in each rows dynamically, so their ServerIDs are not the same (I dont want to use nested gridview). at the end in a button event I want to count checked checkboxes in gridview while I can not use findcontrol() method in each rows to find checkboxes due to their different ServerIDs.
