• Visual Studio 2008 (Pre-release) Root object(class) in Domain Object Model

  I have a question, the question is: In the ADO.NET vNext Entity Data Framework how do I solve the problem of having a root object in my domain model Let's say in my domain object model I have to have a root class from where every other class will be inherited. Obviously the root class does not need to be persisted, it simply adds some behavior to all the objects that I am going to use in my application. While playing with the August CTP, I noticed that I could not make this work. Maybe I'm missing something. Maybe there are ways to get around this problem, can anyone please shed some lights on it What you can do is define an Entity Type in your Entity Model (in the CSDL file) and declare al ...Show All

  Hi, Does anyone know if it is possible to generate a tabbed report to Excel format with Reporting Services Thank you, Ray raymuirhead , When a report is exported to excel, the tab name in excel is going to take the name of your rdl report, but I am having the same problem that you have when I am exporting a report that has a group and a page break is set up in the group.

• Game Technologies: DirectX, XNA, XACT, etc. Camera position?

  How do I calculate the current position, target and up vectors once Matrix transformations have been applied to Device.Transform.View r3n, Ah, sorry I wasn't clear. You would take your view space camera position (right, up and look vectors) and multiply this by the inverted view matrix to get the world space position vectors. To make it more clear, if matrix A holds equations that will transform points from coordinate space A to coordinate space B, then the inverse matrix of A, say matrix B holds the equations to reverse this. So if you have a point, say point 1, in space A (view space) and you want to world space of this point you would multiply this point by the inverse matrix of space A. Sorry ...Show All
