View 1 RepliesI am creating an ASP.NET application that allows users to edit and insert data that is persisted in a SQL Server database.I would like to implement a controller class that handles queries for certain entities, caches results and triggers events when data is inserted or updated.I need one of these controller classes for each entity in my data model.What I'm unsure of is how to create a singleton class of this sort that different user sessions can access.
For example,I have a Employee entity in my data model.I would like to have an EmployeeController class that handles retrieving the employees from the database, sends inserts and updates to the database,keeps a cache of all employees and triggers events when an employee is inserted or updated.Objects in other user sessions could then listen and respond to these events.
Am I on the right track?Should I be using the ASP.NET MVC framework to accomplish this?How do I instantiate these controller classes when the first user needs them and have subsequent concurrent users access the same class?
EDIT:I've been researching the idea of a controller class as an anti-pattern since @TomTom's answer.I'm not convinced one way or the other.I still need an answer to question #3 above.Let's just drop the specific idea of a controller class for now. How do I create any class that is:accessible by multiple user sessions,allows only one instance,is deleted if there are no user sessions,and triggers events that other classes can listen to.
I am not sure how the user defined class objects are garbage collected. Do I need to implement IDisposable interface on every class and call the dispose() method on it to free the memory?
View 7 RepliesI am developing a couple of small ASP.NET application and would like to know what pattern. approach do you use in your projects.
My projects involve databases, using Data access and Business logic layers.
The data-access approach that I was using so far is the following(I read in some book and liked it):
For DAL layer:
Creating an abstract class that will define all database manipulation methods to implement.
The abstract class will contain a static "Instance" property, that will load (if instance == null) an instance (Activator.CreateInstance) of the needed type (a class that implements it).
Creating a classes that implement this abstract class, the implementation will be according to the databases (SQL, mySQL and etc) in use.
With this I can create different implementation according to database in use.
For BLL layer:
A class that encapsulates all all retrieved fields , and static methods that will call the DAL classes.
I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)Code is as follows.

I have a dictionary in the form of: { "honda" : 4, "toyota": 7, "ford" : 3, "chevy": 10 }
I want to sort it by the second column aka (the value) descending.
Desired output:
"chevy", 10
"toyota", 7
"honda", 4
"ford", 3
I was just wondering if I could do anything more or less w/ IDictionary and how these two collections differ.
View 5 RepliesHow do you sort a dictionary object in C# 2.0 for asp.net or is their an alternative to Dictionay for sorting this is to sort a countries list alphabetically
View 3 RepliesI end up with a row for each object in the list, and any cell in a given row is bound to a property of the corresponding object.
However, suppose one of the properties of my object is a dictionary, and each is expected to contain a specific key. Is there any way to bind one of my DataGridColumns to that dictionary key?
Let's say I have a dictionary that I want to store in the session. This dictionary will be storing a list of object with a date as the key.

I'm about to begin an ASP.NET MVC project and I'm not sure how to approach an aspect of the design. Basically, there is a user site and an admin site. In the admin sites, administartors design a form and send an e-mail link out to a handful of people. When the users click on the link, they are sent to the form.
Essentially what I'm wondering is what are the best practices when the model resembles looks more like a dictionary than a table?
In other words, instead of:
CREATE TABLE FormResponse (ResponseId, FormId, UserId, FirstName, LastName, BirthDay, Comments)
...containing 1 row per complete response
It's more like:
CREATE TABLE FormResponse (ResponseId, FormId, UserId, QuestionId, Value)
...containing 4 rows. 1 for the FirstName, 1 for the LastName, 1 for the BirthDay, and 1 for Comments.

how to do routing. My problem basically relates to "logged in" and "logged out routes" and having both as "/".
i.e. I have home/index for logged out user which appears as "/" but this has got me confused as to how I can have home/home for logged in user and still have "/".
I keep getting 127.0.0.1/home/home
I could modify like 127.0.0.1/home - but I want it like "/". My confusion relates to the fact that the "/" [127.0.0.1/] is bound in the routes collection to home/index.
how I can modify the routes dictionary (which will be binded ONCE at the start) so that the "/" can be shared for logged and non-logged users ?
I've got a little problem with displaying my Dictionary in ListBox.
public static Dictionary<String, List<String>> MyDict = new Dictionary<string,
List<String>>();
...
if(MyDict[value1] == null){
List<String> Temp_List = new List<String>();
Temp_List.Items.Add(sth);
MyDict[value1] = Temp_List;
}
else if(MyDict[value1].Count < 4){
List<String> Temp_List = new List<String>();
Temp_List = MyDict[value1];
Temp_List.Add(sth);
MyDict[value1] = Temp_List;
}
and I'd like to display in Page_Load (after logging) a ListBox which will have List from MyDict for this login. Eg.
Login is : sally
And list contains of: she, no, then
And after sally logging I'd like to see result like this:
she
no
then

Is it possible to automatically bind a Dictionary to a Gridview? The closest I've got is:
Dictionary<string, myObject> MyDictionary = new Dictionary<string, myObject>();
// Populate MyDictionary here.
Grid1.DataSource = MyDictionary.Values;
Grid1.DataBind();
This binds the properties in myObject to the gridview, but I'd like to get the key as well. If it's not possible, is there an alternative, e.g. use a repeater?
I try to sort a dictionary with no success
this code i wrote
var sortedDict = _GrandTotalUserDictionary.OrderBy(key => key.Value.Priority);

"key3",
new OrderItem(){title:'c', priority:12}
How do you create a dictionary of objects in the session? More specifically, I have a list of objects: MyList stores MyObject as the result of a linq query with the date as a parameter.
List<MyObject> Mylist;
MyList = GetObjects(TheDate);
Now I'd like to store MyList in the session object in a dictionary with the date as the key. When the page needs a MyList for a specific date, first search the dictionary and if it's blank for that date, get the data from the GetObjects query and store the result in the dictionary in the session.
