State Management :: Common Site And Database Structure?

Aug 2, 2010

Im about to program a common application/website scenario. It contains pages which are presented to users, and some business logic behind, with a database connection class.

My questions are:

Q1: Should the database class be singleton? If so, why? Because does it even matter when every single user is in their own process on the server, and therefore each user has their "own" singleton database instance?

Q2: How would you normally direct users around the site? Would the Default.aspx page create instances of the required classes? And when the user is directed to a new page, how would you normally refer to these instances?

Q3: What kind of general information do you save in the Session variable? Is it a big no-no to save class instances?

State Management :: Redirecting To Different Application With Same URL?

Nov 4, 2010

I have two web applications and sometimes I need user to jump from one application to another. Since they are two web applications( websites) in the same machine, I can not share session between them.

The technical challenge for me is how to pass session information (I only need to pass userID string information in the session) from one source application to another destination application -- so that the user feels Single Sign On and personal information is displayed for him/her in both application (as the userID is passed to the destination application, no re-login is needed).

Another challenge is that when the user jumps to another URL in another application -- I just need to generate the common unified [URL]

State Management :: Redirecting To Home Page When Session Expires?

Oct 14, 2010

my web app doesn't use authorization in web.config, but i want to detect when a session has expired and redirect to the home page.I have searched and found solutions that rely on the web app using authorization. Other solutions have implemented a user control to drop in every page.Obviosly i don't want to manually check for null on every session variable on every event of the web app, so i want the app to do it automatically.

<sessionState timeout="120"></sessionState>
<authentication mode="Forms">
<forms name="myappCookie" loginUrl="~/index.aspx" timeout="120"/>
</authentication>

doesn't work for me since i don't have allow or deny settings, since my app doesn't need authentication.

Web Forms :: Redirecting An Array From One Web Form In The Javascript Section Of The Other Web Form

Feb 16, 2011

I have a web form where I define an array of type struct and I redirected it in the <script runat="server">
section of the second web form. But when I use that array below, in the <script type="text/javascript">
section in the html code of the same web form an error occured in the for cycle saying that the array (Array1) is undefined, and also the counter which I also defined in <script runat="server"> section.

I have this code in the <script runat="server">
section of the second web form:

public struct Point1
{
public float lat;
public float long1;
}
protected void Page_Load(object sender, EventArgs e)
{
//Retreive from session
Point1[] Array1 = Session["s1"] as Point1[];
//Run a Foreach loop
int nCnt
= 0;
foreach (Point1 p1
in Array1)
{
float x1
= p1.lat;
float y1
= p1.long1;
nCnt++;
}
}
and in the <script
type="text/javascript">
section I have:
var
for (var i = 0; i <
nCnt; i++)
{
lineString.getCoordinates().pushLatLngAlt(Array1[i][0], Array1[i][1],0);
}
lineString = ge.createLineString('');
lineStringPlacemark.setGeometry(lineString);

How To Avoid Storing Different Type Of Objects In The Same Place When Represent The Same But With A Different Data Structure

Jan 14, 2010

This is in my opinion an abstract problem and I hope I can explain it well. I happened to find the same kind of problem in a completely different project and now I have it again and I would like to avoid it if possible.

I'm creating some classes to simplify some tasks for some specific requirements we have in some projects at work.

I have a class that creates objects which maps the values from webcontrols to an object properties similar to this

[URL]

The problem I have it's sometimes I have to store a non container object in a place (in an object's attribute) and sometimes I have to a store a container object in the same place for storing the values of a webcontrol (a webcontrol can sometimes hold several values like a checkboxlist). I dont like this at all, because some time ago when working in a non commercial compiler, when parsing and generating the intermediate code I had sometimes to store a container in a place, and sometimes I had to store a non container in the same place, and having to ask in other parts of the code if what you are reading is this type of object, or this another type of object, it is something really annoying and it mess up the code. Is there any tips about what it would be better to do to avoid this kind of situations or nothing can be done to avoid it sometimes?

State Management :: State Management Using Shared Class?

I am doing a POC of making my website run faster. Currently it stores huge object data in Session while passing information from one page to another. What I was thinking is to use shared methods and properties instead of session. It works, but wanted tocheck if this is an optimum way to do it. Below is the code that does not use session but still pass object data from one page to another:

Remembering DropDownList State When Redirecting?

Feb 16, 2011

I have DropDownList, which has some options to choose from. Now after when user selects one of the options, it has to click on a button, which is a redirection on the same page:

protected void Button4_Click(object sender, EventArgs e)
{
Response.Redirect("Graphs.aspx?Selection=" + DropDownList1.SelectedValue + "&Date1=" + TextBox1.Text + "&Date2=" + TextBox2.Text);
}

I have to use redirection instead of postback, because I use flot which is javascript library and all the code has to be written again when user selects some other option. The problem is, when it redirects back, for some reason I can't make it to remember the value in the DropDownList, which has user previously selected. I tried this with this code:

protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["Selection"] == "TemperatureOUT")
{
DropDownList1.SelectedIndex = 0;
}
else if (Request.QueryString["Selection"] == "Dewpoint")
{
DropDownList1.SelectedIndex = 1;
}
}

The problem is, if for example user selects Dewpoint from DropDownList and then clicks on a button, which causes redirection, the new url should have:

Graphs.aspx?Selection=Dewpoint&...

but instead, it says:

Graphs.aspx?Selection=TemperatureOUT&...

Now if I remove that code from Page_Load it works, but it does not remember what has user selected before. Now I know that there has to be something with Page_Load. Isn't that when page is redirected, the Page_Load get's called, so it should look a the Selection value and print it out. So it has to be a problem with redirection, that for some reason does not set the selected value.

State Management :: Application State And Session State?

Oct 2, 2010

User Interface: 2 Labels; 1 Buttons

Requirements: Create a Web Page in ASPx that will do the following:

1)One label will provide a count of how many times Button 1 has been clicked in the current session.

2)One label will provide a count of how many times Button 1 has been clicked by all users of the application. The Application Code for the Button should start at 100 (set this in the Global.asax file). this is what i have so far but i cant seem to get the application state to work properly.

aspx.vb

Partial Class _Default
Inherits System.Web.UI.Page
Dim clickcount As Integer

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Session("ClickCount") Is Nothing Then
clickcount = 0
Else
clickcount = CInt(Session("ClickCount"))
End If
If Not IsPostBack Then
If Request.Cookies("UserName") IsNot Nothing Then
Label1.Text = "Welcome Back " & Request.Cookies("UserName").Value & "."
End If
End If
Dim clickCounta As Integer = CInt(Application("ClickCount"))
End Sub
Protected Sub PostBackSession_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles PostBackSession.Click
clickcount += 1
lblClkCnt.Text = "Current Click Count is " & clickcount
Application.Lock()
Dim clickCounta As Integer = CInt(Application("ClickCount"))
clickCounta += 1
Application("ClickCount") = clickCounta
Application.UnLock()
AppClick.Text = clickCounta
Dim nameCookie As New HttpCookie("UserName", _
TextBox1.Text)
nameCookie.Expires = Now.AddYears(1)

State Management :: Session Mode State Server - Sending Asynchronous Request

Nov 5, 2010

Customer were getting "View State Validation Error" due to worker process recycling at our production webserver and to fix that i applied machinekey and then move my Session state Mode from In Proc to State Server to retain session data and not kick out the customer to relogin. I had serialization issue with one object which has to be stored in session but when i moved it out of session i could able to resolve the issue.

But doing all these i was partly successfull in keeping the user in their session when Worker Process recycle event occurs.I was able to refresh the page or make a post back by clicking the refresh button and also able to retain the session values. But the Problem occurs when sending asynchronous request to server which we do periodically every 15 minutes from the moment the user logs in.The web page doesnot update data on website when sending asynchronous request.By Debugging I found at this particular code point it fails to make a postback which is required.

<%=GetHintFromServer%> (When there is no Worker Process recycle i t gets replaced by
WebForm_DoCallback('__Page',message,ShowHint,null,null,false) on postback) Everything works fine when there is no Worker Process Recyling but when it happens looks like sending request asynchronously using javascript fails .Remember When I make a post back by manually clicking submit button everything works fine.

SendRequest(Asynchronous)
function SendRequest(msg, isBusy, chartMsg, vesselMsg)
{
try
{
//confirm("msg"+msg+"isBusy"+isBusy+"chartMsg"+chartMsg+"VesselMsg"+vesselMsg);
_busy = isBusy;
if(chartMsg != null)
{
//confirm("chartMsg"+chartMsg);
_element.SetMessage(true, chartMsg);
}
if(vesselMsg != null)
{
confirm("chartMsg"+vesselMsg);
_element.ShowVesselLoading(true, vesselMsg);
}
_stuckWatchdog = setTimeout( "ClearPendingRequest();", 60000);
var message = msg;
var context = '';
<%=GetHintFromServer%>
}
catch(e)
{
alert( "Exception error on SendRequest(): " + e);
}

State Management :: Custom Control: State Restoring For Controls Created With CreateChildControls

Dec 22, 2010

Let me explain, describing the scenario:In a custom server control (in my case, derived from CompositeControl), in the overidden CreateChildControls method I create a complex tree of subcontrols, using information from a db.The db provides both information on which controls I need to create (the user interface's structure) and the data used to fill these controls.Than the user can interact with the control and change the data (that becomes different to what stored on db).

My custom control lives in the same page where there are other controls, obviously.And these controls can cause a postback at any time.What I need is that my custom control keeps the data entered by the user across these postback, without reverting to the original data and loose the user data entry.

Here is the first doubt:

1)I create the subcontrols dinamically in the CreateChildControls at any page refresh (both on first call than on postback).I know that the framework solves the reference between the posted data and the controls I create in the CreateChildControls in order to set properties and raise control events, but can you tell me when and how it actually does this? In which phase of page life cycle? What happens after the CreateChildControls?

A second doubt:2)If the user interface structure must change as a consequence of the data entered, I had to execute CreateChildControls twice (the first time to recreate the original interface to get the events and the second time to create the new interface)
In which phase of page/control lifecycle do I have to make the second call to CreateChildControls? I do it on Prerender now, but is it right or wrong, and why?

State Management :: Unable To Serialize The Session State In 'StateServer' And 'SQLServer' Mode

Dec 12, 2010

I am new to .net 4.0 and am using EF Model and SessionState Mode=SqlServer and I am getting this error below:

Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.

I checked the stack trace and its complaining about

[assembly: global::System.Data.Objects.DataClasses.EdmSchemaAttribute()]
[assembly: global::System.Data.Objects.DataClasses.EdmRelationshipAttribute("PoplarGroveModel", "tblMenuRole", "tblMenu", global::System.Data.Metadata.Edm.RelationshipMultiplicity.Many, typeof(PoplarGroveDataModel.Menu), "tblRole",

[Code].....

I marked it as serializable but then it complains about System.Data.Objects.ObjectContext is not marked as serializable and hence throws the same error.

Since then we have are seeing timouts/locks on ASPStateTempSessions table. I am wondering if we have to rebuild this database from scratch with some newer scripts?

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 :: Losing Session State In Global.asax File?

Feb 2, 2011

I am trying to set a session variable in the global.asax file and keep running into the problem that the Session is null.

I am running my application in VS2008 and using asp.net 3.51.

Here is my code:

1. In my web.config file I have enabled the session state and added the following line;

<sessionState
cookieless="false"
mode="InProc"
timeout="60"
></sessionState>

2. In the Session_Start procedure in the Global.asax file I set the session variable to a default value.

[Code]....

My problem seems to be that when the Application_Error procedure is executed the session state is lost.

Does anyone know why the session state isn't available in the Global.asax file.
