I am curious as to the proper technique to use SQL Server's AppRole with a LINQ to SQL Class. I understand I have to establish the intial connection with no connection pooling. However, do I simply call the SQL stored procedure sp_setapprole using standard LINQ before executing any of my methods that interact with the database, or is there a better way to enable and use AppRole within the LINQ to SQL class?
View 6 RepliesI have two classes, one nested in the other. [code]Neither "Name" or "ID" are unique between operations and records.I wish to construct a dictionary using LINQ = Dictionary(Of String, Of List(Of Integer), whereby the keys are uniqe examples of Names in my collection and the values are the collective set of distinct IDs that are associated with those names.
View 2 RepliesI'm using LINQ to SQL as my data access layer for a new project.I have added my database tables to the designer and all is well.Whenever I use one of these classes in a function, Visual Studio warns me that 'Type xxxx is not CLS-compliant' or that 'Return type of function xxxx is not CLS-compliant' Is this a problem with the classes that LINQ to SQL generates? Does it matters? Can I disable these warnings anywhere? My VS error list is clogged up with these warnings making it hard to see anything else.

View 4 RepliesIv'e been away from Visual Basic for the past 3 or 4 years so I am a bit vague on the details that I am looking for.
I got myself my first programming job at the company that I work for and I start Monday.
The company has little programming knowledge (well I assumed this as they said they do not have a dedicated programming IDE at my interview) and relies on ad-hoc VBA scripts to perform necessary processing on data. This is all fine and I can deal with that but there is a project that I wish to work on and I think a standalone dedicated application would be much better than extending Excel with VBA.
Now after being with the company for 10+ years, I know they are conservative at spending money so asking them to buy Visual Studio is not really an option so I'm going to suggest that instead of using VBA, I will design an application using Visual Basic Express.
All I need to know is, if there are any kind of limitation to database accessing with the express editions? (Iv'e only ever used OLEDB connected to small MS Access files) I do not know what type of database the company uses yet, but I do know they use ODBC to connect to it, and rely on Sage to do 90% of their work.
VB.net VS2008 My program dynamically populates a class as I click on specific calendar dates runtime. I am currently using various LINQ statements targeting this class for reporting purposes. However, all of my LINQ statements are hard-coded. Are there available solutions / modules which will provide me with a LINQ command and RESULTS window which can be set to an instance of a class so I can experiment with other commands runtime? Can LinqPad be used runtime against populated classes?
View 1 RepliesI am trying to learn OOD/OOP and read on the net that I am not supposed convert SQL tables into classes. But I cannot find an explanation why not to do it or which tables to skip. So I made an web application based on the below diagram. It works perfectly well. But I do not use OO. which table should not be mapped into a class and why not. do not use LINQ or NHibernate, etc as I do not understand them. I just need to understand the OOD.
View 2 RepliesHow can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:
Public Class MyInterface
Public Economic as EconomicClass
Public Sub New()
MyBase.New()
[code].....
So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:
interface.Economic.MyMethod
interface.Currency.MyMethod
etc
This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.
Here is some example code of what I mean:

Public Class Form1
Private Sub Button1_Click(ByVal sender as Object, e as systemEventArgs) Handles Button1.Click

View 1 RepliesI have an ASP.NET application on our company's intranet. And a funky security requirement.
I need to check to see if a given username is in a certain role. I cannot use
Page.User.IsInRole("MyDomainMyGroup")
because
Page.User.Identity.Name
Returns an empty string. Because of some lovely specifications for this program, I have to keep anonymous access enabled in IIS. Seems to rule out any page.user.identity stuff.
So I did find a way to (at least) get the current user (from System.Environment.UserName), but I need to bounce it against the domain group to see if they're in it. Or, better yet, get a list of users within a given domain so I can check myself. Something like...
Dim UserName as String
UserName = System.Environment.UserName
If User(UserName).IsInRole("MyDomainMyGroup") Then

I just upgraded a project from VB 2008 to VB 2010. Before, the project did not use LINQ. I have started implementing it. So, I have updated the target framework from 2.0 to 3.5, and added a reference to System.Core, and imported the namespace System.LINQ to the entire project and also imported System.Data.LINQ into the form I'm working with (because it was not available in the list for Imported Namespaces in the references tab).
It's not throwing any errors now, but my IntelliSense is not working for LINQ stuff.
For example... I write this:
[CODE]....................
Then, if I type S. on the next line, the IntelliSense doesn't grab what it should for S (Only get Equals, GetHashCode, GetType, ReferenceEquals, and ToString, instead of the options I should get like Count, First, FirstOrDefault, etc...). If I Type S.First. then its the same thing, no IntelliSense that lists the available fields for S, just the standard options (Equals, GetHashCode, GetType, ReferenceEquals, and ToString). I should be seeing my column names in my table when I type S.FirstOrDefault.
So any ideas what is going on? When I type the code, for example, MessageBox.Show(S.FirstOrDefault.FirstName), it works perfectly. But it doesn't change the casing of the text (so it would read s.firstordefault.firstname) and no intellisense while doing it. But no errors. BTW - Everything works perfectly when creating a NEW VS 2010 application, it's just my projects upgraded from Visual Basic 2008 that have this issue.

This desktop app written in VB.Net within VStudio 2008 fails when one of our "power users" tries to run the program: Select permission denied on object 'AcctLogon', database 'MDS', owner 'dbo'. The author of the app is out for a few weeks and I am the "fixer" while she's out. Both of our logins for SQL have permissions for db_owner in the MDS database but our user does not. The user has a Windows user login for this instance of SQL. This login has permissions for the public role only in the MDS database.

I currently have some security working in my application by using the roles and rules, but i wondered whether it was possible to hide web links depending on if a user belongs to a certain role.I currently have it so users belong to either the 'admin' role or 'user' role. Rules have been setup on folders in my application so if a user belongs to either of the groups they can click on a web link and it takes them to the page. However, if a new user registers they belong to no role, and when they click on the web link it redirects them to the homepage (see code below). This is great, but, i wondered is it possible to hide that web link if the user did not belong to a specific role preventing them click on it. Also if a user belonged to no role could they be redirected to a page to tell them they need a role assigned?
