Using Paging in WCF Data Services - Gil Fink on .Net

Sat, 19 Jun 2010 13:57:21 GMT

One of the mechanisms which were provided in WCF Data Services from the start was client side paging. In the new release of WCF Data Services we also get a server side paging and this will be addressed in this post.

Sesame Data Browser has been updated to allow users to create links to OData feeds. It's now possible to use hyperlinks to browse live OData feeds. It's now also possible to quickly filter and sort data.

Configuraing the Data Access Application Block

Wed, 12 May 2010 18:01:30 GMT

I have mentioned Data Access Application Block in my previous posts and I thought it would be convenient to mention how to configure the Data Access Application Block in your project. Mr. Thiru Thangarathinam has written a very nice post about it in very detail hence I'll just summarize it here.

Getting Started with SQL Server Data Access using Data Access Applicat

Thu, 29 Apr 2010 11:40:17 GMT

In this post, we'll see how the same tasks that we did using ADO.Net objects can be done using Data Access Application Block. We will also see how it makes the code much more tidier. Data Access Application Block is part of Microsoft Enterprise Library.

A* pathfinding search in C# - Part 3

Wed, 02 Dec 2009 03:02:05 GMT

This is the last installment in the series about A* search. The C# source code implemented is available in the final part of this post. As promised in the last words of A* pathfinding search in C# - Part 2 today we're gonna run a test case using the Romania map. This post shows a test case in which the application outputs the shortest path from Arad to Bucharest. I used the ViewOtherPaths method to show the different possible routes. This way we can have a look at why the A* algorithm has chosen such shortest path.

A* pathfinding search in C# - Part 2

Wed, 02 Dec 2009 03:00:57 GMT

This post describes step by step the methods used to implement the A* search algorithm. To illustrate the path finding problem and how it can be solved using A* I decided to use the Romania map (with the same Cities I used in Breadth and depth first search series of posts). Now I modified it adding more connections between the cities so that we have more fun while debugging the code. This time I decided to get the real values of latitude and longitude for the cities shown in the Romania map. See how a graph of cities is assembled using the real geocode values for latitude and longitude using Google Maps service.

The Only Pattern for Data Access is There Are No Patterns for Data Acc

Tue, 23 Jun 2009 02:03:31 GMT

Over the years of software development, one thing that has eluded most developers is Data Access. Yes, I mean writing code that accesses a database from your application. It is an age old problem since the days when data storage and computing were invented. We would have thought that by now we would have been able to come up with a clean universal pattern for data access such as the M-V-C pattern for User Interfaces or the Singleton pattern or the Factory pattern.

A* pathfinding search in C# - Part 1

Sat, 20 Jun 2009 21:49:35 GMT

Standing on the shoulders of giants just like Eric Lippert, this is my try to create a running sample of the code he has presented in his magnific series of posts titled Path Finding Using A* in C# 3.0. Eric wrote the base structure of the A* pathfinding algorithm but didn't provide a complete running sample. I basically added some code I had already posted on the series of posts titled Breadth and depth first search and created some properties here and there to get the whole thing running. It's nothing more than code reuse. In this implementation you'll find interesting data structures as a priority queue and and immutable stack.

Dynamic Data: Tweaking the Filter Repeater

Fri, 26 Sep 2008 02:20:06 GMT

The default implementation of Dynamic Data provides a drop down list box for each foreign key and boolean field in a table. The drop down list allows you to filter the table with the value selected from the drop down list box. The figure below shows a view of the Product table from the AdventureWorksLT database. Several columns are not displayed because the scaffoldcolumnattribute was applied.

Free Data Structures and Algorithms book

Fri, 29 Aug 2008 09:43:02 GMT

This book written by Granville Barnett and Luca Del Tongo is part of an effort to provide all developers with a core understanding of algorithms that operate on various common, and uncommon data structures. Data Structures and Algorithms: Annotated Reference with Examples is completely free!

What's the difference between Bind and Eval

Fri, 01 Aug 2008 16:25:46 GMT

Data-binding expressions are contained within delimiters and use the Eval and Bind functions. The Eval function is used to define one-way (read-only) binding. The Bind function is used for two-way (updatable) binding. In addition to calling Eval and Bind methods to perform data binding in a data-binding expression, you can call any publicly scoped code within the delimiters to execute that code and return a value during page processing.

JSONLint - Online JSON Validator

Sat, 26 Jan 2008 16:21:25 GMT

A site that allows you to enter JSON text and check it for strict compliance against the standard (RFC 4627). Errors are pointed out with quite good accuracy, highlighting the offending area. The output is also pretty-formatted. The only downsite is that your JSON text is processed and validated on the server so don't use this facility to validate JSON text containing confidential or sensitive data.

Microsoft Codename "Astoria": Data Services for the Web

Wed, 02 May 2007 15:31:02 GMT

The "data programmability" team at Microsoft is responsible for the various technologies developers use in applications to access and manipulate data. One of the topics we have been looking at lately is how "new" internet applications use data in the web environment. Project codename "Astoria" reflects our current thinking on the topic. Instead of telling "what we are going to build", we decided to make the bits and infrastructure public for the development community to look at and give us feedback.

Free Xceed DataGrid Control for WPF Released

Fri, 26 Jan 2007 02:14:08 GMT

Xceed has decided to release their fully-functional, professional-level WPF DataGrid control completely free. No, this isn't a time-limited or "lite" version of the control...it's the real deal. When you consider that WPF version 1.0 doesn't ship with a data grid control at all, you'll realize that an offer like this is very compelling.
