I get the same error with this vb version of the project.

"System.Windows.Ria.DomainOperationException: Load operation failed for query 'GetRestaurant'. Access denied to DomainOperationEntry 'GetRestaurants'.

Th c# project does not have this issue. Both projects complain that a Type 'DemoControls.ColorPicker' is not defined, and related msgs. At least this project runs (search does not work).

This kind of stuff is hard for newbs to debug; hopefully someone who knows more can help with a solution.

Hi Brad, Thanx for your example. But I have some problems

1- My database is Oracle how can I connect with it.

2- I have 150 tables at my hr can you give me a method for dynamic binding Ex: one or two classes for many forms (it is better for maintenance).

3- I need a method for modal dialog that return one or more value to the parent form.

4- What about reports?

That is my problems to transfer my business application.

Thanx again

Hi Brad, Thanx for doing this in VB too - makes me feel like I'm not the only one developing SL in VB.. ;)

I've downloaded the app, but when running it i get the following error "System.Windows.Ria.DomainOperationException: Load operation failed for query" (GetRestaurant)

Any idea why? - I guess its something with access to the mdf file but I've given my sql service account (Network service) and everything access to it so..?

Any help greatly appreciated!

Thanks Brad,

Like Ranjit, I’d love to see you add a data bound Combo box to the Data Form of your example and learn how to hook it up to the Master data (for instance a "Food Type" category) .

Its question I've seen posted on many sites but have yet to see a satisfactory answer. Really hoping this has been addressed in SL4.

Cheers

Hi Brad,

Thanks for getting a VB version up.

Quick question: During your presentation, you were doing zooming and also you turned on a red line drawing tool. Can you share how you did these two really helpful actions?

Thanks ... bill burrows

Brad,

Great demo in terms of LOB applications. can you pls demonstrate how we can use a Combo box in a DataForm? Quick scenario: In a user management form there is a role dropdown, the role lst is populated from a different table and upon a role selection the roleID is stored in the Users table. This is pretty common scenario in our LOBs. can you pls give us some insight on in terms of RIA and SL4??

Thank you much.

It is too bad not a single demo I saw at PDC was in VB. Seems like Microsoft is forgetting the language that got them where they are today.
