Can someone explain me what is is the relationship between App Domain and thread? msdn says "threads are free to cross application domain boundaries; a new thread is not created for each application domain." suppose there is one thread t inside Appdomain a1 .there is an another App domain a2 .thread t can cross to a2 from a1 means it can access a2 memory area If thread can cross the app domain boundaries share the memory space then how application domain isolation is still there?
I have to create a very simple database driven website ( for a project ) with basic features like a login system, etc. I have completed most of the basic tasks required, but there is one section that is asking me to 'Use persistence to maintain state/relationship'.
I have read a few articles and videos about persistence but I don't understand its benefits and why and how it should be used. Can anyone point me towards a site that explains how to implement state persistence in a simple way. I don't need anything advanced just a very simple way of integrating this into a very simple site to say its been done.
I think I'm just after advice on best practice with this! I have a database which has 2 tables. The first table has ID, Name, Address and the second table has ID and JobType. Table 02 can list multiple types of JobType so we could have
Table01:
1. D Smith. Address01 2. S.Jones. Address02
Table02
1. Accounts 1. Sales Ledger 1. Chartered Accountant 2. IT 2. Web Design 2. Graphic Design 2. 1st line support
A join gets them together and all works perfectly.However, the content will be updated when some one fills in a web form. Do get the form to send results to both tables, I assume I have to open the database twice or can I open it once and open each table one at a time? I know I could practice this and not ask the question but I am interested to know what is the most efficient way. I would also need to know what ID to use. So when I populate Table02 it uses the correct ID from Table01. At the moment Table01 ID field is incremented automatically. Would you suggest I always assign the ID myself, or would I need to query the database, find out what ID number is currently in use and then increment it by 1 and assign the new number to an ID variable which then populates the Table's Field? In which case, am I opening the database again or trying to perform all 2/3 stages in one go?
I want to display details STRONGLY TYPE In a view this would be done as normal through the list, hiting the details link. however a table of notes is connected to the main table of info. i want to us the id of the main table item to list all the notes that have been entered about the record in the main table. how do i do this
I'm trying to understand the relationship between assemblies, namespaces and classes. Can anyone help explain or point me to a usefule link?
1. I understand that an assembly is typicall a dll or an exe (perhaps other files also). Does each project compilation produce only 1 dll? Or is the number of DLL dictated by something completely different?
2. I read each assembly can contain multiple classes. Asingle assembly can contain classes for multiple namespaces, and asingle namespace can span multiple assemblies.
I have an ASP.NET project where I want to keep the membership (SQL Provider) in a separate database and the Roles/Profiles will be per application.QuestionWhat is the KEY that relates between the Membership database and the Roles/Profile database? Is it the UserID or UserName?I opened up the tables in separate expolrer and notice the UserID is different in the Membership database from that in the application Roles database.
i am working with multiple table with some same columns, so here i want to use the concept of primary key and foreign key.primary key is very easy to put on any fields but, i dont know how to give foreign key and how to create relationship between same fields of two table.

I have a database which contain job ads/ I have one table "dbo.tbl_jobadvert" which contains the ad itself and another table "dbo.tbl_jobFiles" which contains the path of the documents uploaded in relations to the job advert ( application form, job description, etc )
A co-worker of mine just came back from a SQL Server Reporting Services class (we are using SQL Server 2005). In that class they were told that if they had a one to many relationship that they would have to flatten the results into one row of the resultset in order to show the 'many' portion of the relationship. For example, my company has two tables:Jobs Notes/Memo'sor each Job we can have 0 or more Notes/Memo's.According to my co-worker the Report Server must have each of the Notes/Memo's in one row of the resultset. That we therefore have to flatten the list of Notes into Note1, Note2, Note3...etc fields.Is this correct? How would I handle a situation where I didn't know how many Notes there were?
I have 2 objects, that can exist seperately - lets say man and woman, neither needs to know about the other. But once they get get "married" it can only be married to each other. In other words, I'm trying to create 2 tables, 1 table has a FK to the other, that is NULLABLE. When i try to set the relationship to 1-to-1 via the dmbl, it wont let me - which makes sense. Ultimate i want to
1) create a women (no knowledge of a man)
[Code]....
Is this even possible? If i do a one-to-many - how can i make it act this way? At the business layer? create a partial class and override stuff?
We have an ASP.NET web application that has been around for over 4 years now. The web app uses ASP.NET role management with a custom role provider. The custom role provider connects to a database which includes tables for Users, User Groups, and Roles, with a table linking roles to user groups.
Over the years the application has grown in functionality and roles have been added. We now have around 30 roles and there is a complaint that it's not clear (due to lack of documentation, bad naming or whatever) what functionality a particular role gives a user.
Is there guidance on how to make the relationship between roles and functionality more transparent? list out the application functionality in another table and create a relationship between Role and Functionality. The application security would then be programmed against the items in the Functionality table, and the relationships between role and functionality could be maintained through a UI.
To me this approach doesn't quite fit with the concepts behind ASP.NET role based security. All the framework code methods refer to roles, e.g. "RoleProvider.IsUserInRole(string username, string roleName)" and:
In SQL, I have:[Bands] 1 ---- * [BandsGenres] * ---- 1 [Genres]In my EF layer, it translates to:[Bands] * ---- * [Genres](BandsGenres is BandId and GenreId)My problem is, I can't seem to figure out how to delete just the selected relationships I need. Basically, I'm trying to update a list of type Genre for a band. A list of Guids is passed in and I'm able to get those using joins. However, the .Remove() method isn't removing the old genres and adding the new ones. I tried using .Attach(g) and .DeleteObject(g) but that removed the actual Genre (from Genres) instead of just the relationship.
[code]...
How can I delete/add or update my list of genre relationships for a band, given a list of genre IDs?
I'm quite confused about how to implement a many-to-many relationship and my domain model. Let's say I'm creating a recipe box web application and I have three tables called Category (categoryID, categoryName), RecipeCategory (categoryID, recipeID), and Recipes (recipeID, recipeName, recipeDescription). If I were to present this information as an ASP.NET application and wanted to insert a new recipe and category, am I responsible for writing the logic to insert the information in the RecipeCategory table OR is it possible to set RecipeCategory.categoryID and RecipeCategory.recipeID automatically with default values based on newly inserted records in the related tables? If I'm responsible for writing the logic to insert values in RecipeCategory.categoryID and RecipeCategory.recipeID is that a trigger? What's the best way of implementing this?
I have 2 tables. Table_A has one to many relationship with Table_B.
For example. Table_A has an ApplicantKey and in Table_B I am storing (Resume_name and CoverLetter_name for the Applicant). Joined by ApplicantKey
Now when I join them and execute the query obviously it returns me two rows. But what I want is that it should return only one row with Columns like Resume_name, CoverLetter_Name
I have a one-to-one relationship on two tables with are represented by 2 classes in my EDM. I am trying to save a new record and am confused how to save to the second entity. I have tried the following.
Dim myObject as new MyObject myObject.prop1 = 5 myObject.prop2 = "Test" myObject.myOtherObject.prop1 = 3 myObject.myOtherObject.prop2 = "Hello"
But I get an error when I hit myObject.myOtherObject.prop1 = 3 because myOtherObject hasn't been initialized. How do I initialize an child object under myObject?
