State Management :: Creating Cookie With Client Scripting And Updating From Server Side?

Aug 9, 2010

cookies are generated from the client scripting.e.g. document.cookie = city=NYC;

I want to update this from GUI using

Response.cookies["city"] = LA;

I could not understand why this is not possible.( I read about Httponly and all that stuff but still not clear).If I use Javascript in code behind page then I am able to change the value.e.g.

Literal ltMsgUpdate = new Literal();
ltMsgUpdate.Text = "<script type='text/javascript'>document.cookie = 'city=LA';" + "</script>";
Page.Controls.Add(ltMsgUpdate);

But I could not use this type of code because there is response.redirect statement in the function where I am updating cookie using (response.cookie) and that's why the javascript code never runs.

Bottomline: I want to update cookies in code behind page which is generated in client scripting.

How To Find From GUI Whether Client Side Scripting Or Server Side Scripting Is Running

Mar 16, 2010

We have a GUI which runs on ASP.NET 2.0 framework (Client-Server model). From the support perspective how can one find whether the pages which are opening on GUI at any point of time is a server side scripting or Client side scripting.

The reason why I ask this is because I understand that some of the codes are executed by the browser such as Javascript. So, if there are such scripts which are handled by the client browser, how can one find out that it is the Client side scripting which is running at that moment.

State Management :: Updating Cookie / Change The Value In A Cookie?

May 10, 2010

I want to change the value in a cookie:
HttpCookie hc = new HttpCookie("HiddenColumns");
hc.Value = customView.HiddenFields;
hc.Expires = DateTime.Now.AddDays(365);
Response.SetCookie(hc);

Or this way:

Response.Cookies["HiddenColumns"].Value = customView.HiddenFields;;
Response.Cookies["HiddenColumns"].Expires = DateTime.Now.AddDays(365);

But when I retrieve the cookie value, it is still old, unless I do postback. I don't want to use Redirect.

State Management :: Cookie / It's Cause The Sql Server Update Twice :|

Dec 22, 2010

I have a website of online games and I try to count and show the number of the uniqe visitor per game page, by using Cookies only. (if someone visit after 24hr it will be uniqe visitor too)

the problems is:sometimes (I don't know why), not always, it's update the counter colomn of the game, +2 instead +1, and I don't know why, there isn't any "for loop" etc.. maybe is't because the url rewrite? but it work fine if people enter again the colomn will not update again, the problem is that is update +2 instead +1 (see the code at the bottom)this is my algorithm (something is wrong in this algorithm so don't use it):

1. put the query string in variable (the name of the game) - i'm using url rewite.


2. use this variable for select the game Name (and another information) from the database (and for the cookie I will use the game name from the database and not from the query string to avoid from capital letter problems, because cappital letter for the first word isn't good because words like of, to etc..).


3. for each pageload (there isn't postback in the game page) check if the cookie of the uniqe game exists

4. if not exists, create a cookie for the unique game (the name of the cookie and the his value will be same, because I don't care about it, it's only for check if the cookie exist, and I can't use one cookie for all the games because each time visitor enter the cookie will create for 1 day).

4. after this creation of the cookie try to find if the cookie exist (for cheaking if the user didn't disable the option for cookies)

5. if yes update the database column of the spesific game

the code:

In the end of the page_load - (the GameName is the virable of the name of the game from the database and not from the qury string).

[Code]....

and the update function

Why Are Hidden Fields Considered Client Side State Management

Jan 24, 2011

According to MSDN and the MCTS self-paced training, asp.net can use Hidden fields for client-side state management. The book material goes on to say view-state is more secure than hidden fields because the data is encrypted. I must be missing something here. I setup a Label and made it hidden. I can store data in this hidden label and it won't even be sent to the client browser. This not only works like server side state (note the runat=server), but this seems more secure than view-state because there's no need for encryption as the client can't even see the field.

<asp:Label ID="Label1" Visible="false" runat="server">secret info</asp:Label>
<input id="Text2" type="text" style="visibility:hidden;" value="secret 99" />

JavaScript - Exposing Server-side State Through Client-side Controls

Feb 11, 2011

I have a list of items on an ASP.net page. That list is selectable in that whenever the user clicks on one, the page does a postback and the server code stores the index or some unique identifier of the picture in a ViewState property indicating that it is currently selected.

I would like to minimize the load on the server and therefore I would like to store the index or unique identifier representing the image in some way on the client side. The best way I can think to do this is to store said information in a hidden field ), however I had two questions about this before I go crazy:

Is this a security risk in any way, shape or form (i.e., exposing implementation details of the page)?
Is there a better/best way to do this that is more industry-standard? Does ASP.net provide a framework to do this that is cleaner than my idea? Seems like this would be a fairly common requirement to me...

State Management :: Persisting The Cookie Across Development And Production Server?

Jan 2, 2011

I am using this code to pass variables from ASP.NET application to HTML Application:

[Code]....

The above code is run from page_laod event, and I am making some development changes on the Development Machine (say
http://eutdev02/ehrmd).

After the ASPX page is loaded, and I debug the javascript in the HTML (F12 under IE8), and can see the Cookie is found in the browser.

But, when I open the target HTML/Javascript web page (which will read the cookie prmStaffID), but the HTML Page is on the production machine (separate server say

http://prod01/Attendance.html), the Cookie is not found !!!

It seems to me that Cookies will persist only on one IIS Server, and will not be global.

Question:How I can persist the Cookie on the Client Machine regardless of the the Server Machine ?

For testing purposes, I want to send the cookie to the client from teh Development Server, but the target application is under HTML/Javascript, and I want to be able to read the same Cookie using Javascript.

State Management :: How To Use Current Session (webpage) In Client Side ActiveX Control

May 3, 2010

I'm curently developing web application which uses standard form authorization and, of course, server session objects (quite classic app). Now I'm developing client side component, which base functionality is to allow users to acquire tiif/jpg/pdf document from scanner (client side) and send it to server. Because of scan complexity and need for very user friendly interface i decided to implement Activex object (object written in .net 2.0). Until now all was ok, so I have got activex which succesfully registers and scan documents on client - but i cannot manage with sending files to server.

My concept of sending files was like that:

- preparing Upload.aspx web page wich is used for reciving files sended by POST method and saving files in database (of course to proper save in database i need some current user context information) - in ActiveX i decided to use System.Net.HttpWebRequest object to prepare and send data the problem was third point:

- i thought that in-proc activex object would "derive" web session form web page activex is placed on - but i was wrong (or i made it wrong). Whenever i send request form Activex, in response i got login.aspx page - so it looks that new session is created and new authorization is needed.

I was trying to pass to my Activex values stored in "ASP.Net_SessionId" and ".ASPXAUTH" cookies, as i found that these are the values identifying session and athorized user - but with no luck.

I think, that becaause HTTP is stateless protocol all information needed to "connect to/share" existing session on IIS server need to be included in request data, so there must be way to add these information to request sended from my activex.

I would be very grateful, if someone could provide me information what should i add (headres/cookies/etc... ?) to my request data so it could share session from "parent" web page.

State Management :: Asp Create New Session State Cookie Each Time On Debugging?

Jan 21, 2011

I'm using the following line of code to display the number of users currently logged on:

lblNoOfUsers.Text = Membership.GetNumberOfUsersOnline().ToString()

I'm still debugging my application so it's on the local server. As I debug and stop then debug again, eventually lblNoOfUsers.text turns to "0" instead of "1", even as I'm navigating my application. It only turns to "1" again if I log out and sign back in. It's almost as though Membership.GetNumberOfUsersOnline my login are referencing two different session states. How is this possible? Does asp.net create a new session state cookie each time I start debugging?

State Management :: Server-side Detection Of A Changed Form?

Mar 7, 2010

I've searched high and low for a efficient and reusable way to detect, on a postback/server-side, if any input controls on a form have been changed and I haven't found anything other than client-side solutions such as DirtyUpdatePanelExtender. I've come to the conclusion that it must be either really simple or really complicated.Ultimately what I want to do is to perform a database update, or not, depending on whether or not the user has changed any input controls on the form. The only thing I've come up with so far is to save the original values as Viewstate variables and then compare them with the Request values on a postback, but that seems far from ideal.

State Management :: Passing Data Client To Server Using Hidden Field

Mar 26, 2010

I am trying to pass data from client to server using a hidden field. If I use a button, then OnClientClick sets the value, and OnClick does the postback and all is well.

However, I am responding to a Client event, and although this works I get no postback. How do I now force a postback from my client handler?

Response.Cookie Client Or Server/where Does The Cookie Saved? On Client Machine Or Server Machine?

Mar 7, 2011

When calling Response.Cookie.Add(new HttpCookie("MyCookie", "objValue")); where does the cookie saved? on Client Machine or Server Machine?

EDIT:if saved in Client Machine, how can I read it from javascript then? I tried this kind of script.

function getCookie(c_name) {
var i, x, y, ARRcookies = document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {
[code].....

I cannot get the cookie that I saved from code behind. When I look into the document.cookie object, it is just an empty string.

Scenario:On Page_Init() on code behind. I create a cookie using Response.Cookie.Add(new HttpCookie("MyCookie", "cookieValue"));.
On Client side, I'm trying to read the cookie saved from code behind on page load using the snippet above, but it returns undefined

Call C# Or C++ From Html Pages For Server Side Scripting / Programming On Localhost?

Sep 25, 2010

I am running Aprelium Abyss Web Server from my home computer and I have a plain old normal website. You know how you can have separate PHP files, and then call the functions inside of then within the HTML page using the onclick="" of a button? Well, I have a C# and C++ program on my computer (where the server is located), and would like to know if I can somehow send a command from my html page to my C# or C++ program which will then execute a function, and return a result. Here's a scenario: User visits [URL] User clicks the 'Create some files' button on the webpage Webpage sends command to C# application on my computer/webserver C# application creates a bunch of empty files C# application sends back filenames of the generated files to the webpage the webpage then displays a list of the filenames that were generated byb the C# application. Can somebody please guide me in the right direction?

Javascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked

Nov 23, 2010

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)

<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...

There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)

<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...

There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.

<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

State Management :: Cookie Value Disappeared?

Feb 13, 2011

We are using asp.net and 3.5 framework. I have a process that sets the value of a cookie named "mystaffid" in the Default.aspx code behind page. This holds the unique ID of the internal user (intranet). Now when I leave one of the web pages to go to another page in the same website I am getting the error "Input string was not in a correct format. " on the 3rd line below. how the cookie disappears? Also, this is happening in the Page_Load of the master page and I am doing the exact same thing in other pages with the same master page and not getting the error. The cookie is set to expire in 1 day when it is set in Default.aspx.

Dim intStaffID As Int32 = 0

If Not Request.Cookies("mystaffid") Is Nothing Then
intStaffID = Convert.ToInt32(Request.Cookies("mystaffid").Value)
End If
