Data Binding to Anonymous Types in Silverlight

Trying to bind Silverlight controls to anonymous typed objects will not work, this is because anonymous types are internal, and Silverlight doesn't support reflecting against internal types.

Documentum DQL Query Custom Data Extension For SQL Server Reporting Services

When it comes to Reporting SQL Reporting Services is my favorite choice. SQL Reporting Services has a plenty of data source types but unfortunately Documentum is not one of them, whenever we have to develop some reports based on the data in Documentum we first develop a web service that contains the necessary DQL queries and returns the result in a Data Set, then we create an XML data source that consumes this web service and use it in our reports. Fortunately SQL Reporting Services allows you to extend its data access capabilities by developing a custom data extension (CDE)that retrieves data from your custom data source. I developed a Custom Data Extension for Documentum that allows you to specify a Documentum Repository as a data source and provide your DQL query that will populate your report, I used the Reporting Services SDK Sample (FsiDataExtension) and this Article as starting points You can download the extension from here To install the extension: you have to install the ex

Luckily for us Windows Phone 7 uses Silverlight as its development platform (along with XNA), the Silverlight version on Windows Phone is not the same one as the desktop version, think of this as a compact version that fits the phone capabilities. Before we start creating the phone application, first let’s think how we will bring the data to the phone, in the case of the Silverlight application we used WCF RIA services (DomainService) which provided rich client experience for the Silverlight application, Unfortunate

Recently Microsoft released Tools for Apache Cordova Command Line Interface (TACO CLI), by using TACO, you can quickly start building awesome Apache Cordova apps really and leave all the plumbing of the different platforms dependencies, plugins, etc. to the tools to take care of. For example the following few commands create a cordova project based on the ionic base template, add the android platform to the project, install the platform requirements, build the app, and run it in the emulator: $ taco create sampleApp --template https://github.com/driftyco/ionic-app-base $ cd sampleApp $ taco platform add android $ taco install-reqs android $ taco build android $ taco emulate android Check the TACO home page of for installation instructions and more information http://taco.tools/ . I ran into a problem when i created a new project based on the ionic base template and tried to run it on a windows 8.1 emulator, to reproduce the issue use the following taco commands to cr
