Silverlight 5 P-Invoke: Using Kinect SDK from Silverlight

Image
Away from all the discussions about whether Silverlight is dead or not, The Silverlight 5 RC contains the previously announced P-Invoke feature which enables you to call Win32 style APIs from a trusted Silverlight application. There are some attempts to use Kinect from Silverlight ( here ) but this was before MS released the official SDK. we will use Silverlight 5 P-Invoke feature to call the Kinect SDK APIs. P-Invoke in Silverlight works just like P-Invoke on the desktop. you use the DllImport attribute to import the APIs and you declare in your code the dependent types (Enums, structs, etc.) [ DllImport ( "MSRKINECTNUI.DLL" )]        private static extern HRESULT NuiInitialize( uint dwFlags); I tried to keep the classes and methods in library identical to the ones in the official SDK.

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...

Problem Statement as part of our community activities we hold many offline events, at the event we need to gather the attendees information(sort of onsite registration), give them feedback forms so that they can evaluate the sessions and also use these forms to select winners for the raffle draw. so i tried to create a simple application that we will host on a PC/Laptop at the event venue, we will call it the RegistrationBooth Application. Solution  the RegistrationBooth Application will: - Allows the user to register his/her information through a simple easy interface. - Automatically print a name tag for the user once registered. - displays a list of all the registered users. - displays the event agenda. - allows the users to easily evaluate the sessions ...
