Create A Copy Of An Object In Session To Update Without Updating Session?

Jul 20, 2010

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?

Subtract 1 Year From Datetime?

Apr 30, 2010

I have seen a lot of info on how to subtract one datetime from the other and how to add years on to a datetime. but the following is giving me a headache....When a user inserts a record a hidden field called subdate with a value of datetime.now is added to the db.I then need to have an 'old records' page that lists all the entries that are over 1 year old and was hoping to use something (but using subtract method) similar to;

(DateTime.Now.AddYears(1))

but there is no SubtractYears available? Why?

Access :: Access/SQL Selectcommand And Session?

Nov 22, 2010

I have the following two pages. One is a search page that have a few listbox/textbox/and dropdownlist. The other will be the result page that take from session those 3 data and using an if/else statement to sort out some detail. After that it will form an access/sql selectcommand to search the database base on that 3 criteria. But for some weird reason only the first part of my if and else statement work. Can anyone check and help me out why the rest of the if/else doesn't work. Or point me to another direction?

MVC :: Access The Session On The Controller?

Jan 30, 2010

I am trying to get into grips with AJAX/JQuery and MVC. i need to access the session on the controller. This doesnt seem to be initialised at the constructor level but there needs to be a way I can store items in the session in the constructor depending on the parameter values (an extra constructor is written here) I am also doing unit testing here, which has been provided by 3rd party and they are using this extra constructor.

So the idea here is that when the page is loaded, JQuery will request a collection of items (which will be stored in session) and also be able to post to the page so items are added into the collection too. So, what is the best way here to get access to the session in the constructor of a controller?

How To To Access The Session In A WebMethod

Dec 7, 2010

I have a pagemethod defined with the attribute [WebMethod]. The pagemethod accesses the session with no problem (HttpContext.Current.Session).

However I just read somewhere that in order to access the session in a WebMethod, you need to define it like so: [WebMethod(EnableSession=true)]

So my question is, what gives? How come I can access the session even though I dont have that code? Apparently EnableSession defaults to false if its missing, so I should not be able to access the session. The web application uses ASP.NET 3.5 and uses InProc Cookieless sessions.

C# - Session Object Is Null After Update?

Mar 27, 2011

I'm populating an object model with a linq query. The model looks like this:

MyModel{
DateTime AppointDate {get; set;}
int TotalAppoints {get; set;}
int AppointDuration {get; set;}
}

The linq-to-sql query looks like that:

public static GetAppointsFromDB(params){
var MyQuery = from....where...
select new MyModel{
AppointDate = ...,
TotalAppoints = ...,
AppointDuration =...};
return MyQuery as MyModel;}

In the master page, I'm looking to load the result of this query in the session like this:

if (Session["Appoints"] == null) {Session["Appoints"] = GetAppointsFromDB(...);}

When I run with the code, the session is always null. I added this line a second time, just right after, and the query runs again. When I'm looking to use the session at some other point in the code, it is null too there too. The query works because when I put a breakpoint on the return statement, I see the object properly filled.

How To Access The Session From A Different Project Within The Solution

Feb 4, 2010

I have 2 projects in my solution.

MVC Web application
Class library

The MVC Web application references the class library.

The class library contains a class that extends the default ASP.Net Controller.

I'm putting a variable in session in the application's Global.asax.

protected void Session_Start(object sender, EventArgs args)
{
HttpContext.Current.Session["DomainName"] = Request.Url.Host;
}

In the class library I'm trying to get the value from the HttpContext.Session, but HttpContext.Session keeps coming up null.

[code]...

HttpContext.Current.Session doesn't seem to be an option in controllers.
