I have been adding animations to a Windows Phone 7 app that has a panorama control and ran into a problem I have seen others post online. I figured it out, so I thought I would take a minute to explain how. Get ready to add transitions The Silverlight Toolkit is the way you want to go about adding quick and easy animations when a page loads and navigates away from the current page. If you are not familiar with the basics visit the link above, or read this really good tutorial about wp7 page transitio... (more)

I was in Redmond this last week and talked to Jeff Derstadt, the Lead Developer on Entity Framework Code First (or, as I say, EF Magic Unicorn). What's the deal with this new feature in Entity Framework? What about the bad rap that EF got back in the day? What's new in EF4 and how does EF Code First sit on that? Which is the right choice, Model First, Database First or Code First? All of this plus demos in this off-the-cuff interview. There's lots of good info in this video including some insight into mu...

Using EF 4.1 Code First to support multiple database vendors

With the release of the Entity Framework 4.1 I was interested to see how well the code first aspect works with multiple database vendors.  Could you use the code first modeling to change the database through a connection string?  I thought it might be worth a quick sample app to find out. I have an identical database in both SQL CE 4 and VistaDB 4.1.  Since they both have ADO.Net providers for the Entity Framework I decided to use them for this test... (more)

LINQ Query Pane in VistaDB 4.1

There is a new pane in the Data Builder for VistaDB 4.1.  The LINQ query pane is a very handy way to build and test LINQ queries against a simple Entity Framework model.  First understand that this pane is a work in progress.  It was designed to be an easy way to write LINQ queries (similar to LINQPad) for your VistaDB database.  The feature is of limited usefulness since the model cannot be customized at generation, or loaded from your own assembly.  But this is where we were with the feature when we ha...

LINQ Group By with NULL database values

LINQ is fantastic for the ability to write queries that express intent much more clearly than the same SQL, or structured code.  One problem that I have run into though is handling NULL database values that are part of a group by statement.  Grouping by ProductSKU Grouping in LINQ allows you to return sets of data from a collection for a given key value.  The group by clause is what the key ends up being in the result set.  Lets take a grouping of the Products by the SKU.from p in Products group p ...

ClickOnce applications have many benefits including ease of deployment, optional automatic updates and framework requirement checks.The only real complicated issue with ClickOnce is how to deploy the database. I can’t imagine trying to deploy Sql Server as a part of your application! VistaDB is a perfect fit to be embedded in a ClickOnce application due to the ease of XCopy deployment. Our 100% managed engine means you don’t need any permissions on the client side, no installs or registry permissions are... (more)

Native .NET Local Storage with VistaDB

Wednesday, June 30, 2010 8:25:58 PM GMT
Distributed applications often need local storage. The requirements for local storage are adequate performance, reliability, integration with your existing tools and ease of deployment. VistaDB scores well on all of these fronts. While compact, VistaDB doesn't skimp on database technologies you'd expect, providing referential integrity, views and stored procedures, and a transaction monitor. Granted, in the Microsoft .NET Framework, all database engines tend to look alike, but the people at Infinite Cod... (more)

Building a plug-in model to load VistaDB - Part II

Plugins are used in data applications to support more than one provider from a single codebase.  The Provider Factories in ADO.Net is one such example, but you cannot work with the provider specific features when you use these factories since they only implement generic ADO.Net functions.  If you need to be able to use provider specific functions (like VistaDB’s DDA Pack routines), you have to load the provider somehow.  In most cases you put that logic and bindings into a separate assembly and load it w...

In this article I will explain how to build an application that uses VistaDB and Microsoft’s SQL Server, without being hard bound against their providers directly. Many companies desire to offer the choice from several database providers in a single product or API.  In many cases if you were directly bound, but the provider not installed, you would get a dll not found exception at startup.  There are two ways to handle this scenario.  The most common method is to use ADO.Net Provider Factories and load...

After reading Scott Hansleman’s article on exposing OData for Stack Overflow I thought it would be nice to update the previous post I did on Ado.net data services to include the new WCF Data Services.  WCF Data Services (formerly called Ado.net Data Services, and “Astoria”) can expose OData to callers through a very simple interface. LINQPad was not available to query the interface at the time, so I will also discuss how to use LINQPad to write queries against a Data Service. For my example I am going t... (more)

[Mainly in reporting.] From the UI, users selects the date and by using that date we need to compare the datetime field in database and produce some result. But, in database it actually the datetime field, we can't apply equal operator on it as it fails to do it because of time part. I know, now there is... (more)
