• Game Technologies: DirectX, XNA, XACT, etc. Render to texture and Volume Textures

  Hi, I would like to know whether Direct3D can perform render to texture to a "slice" of a volume texture. Its just like binding an slice of a 3DTexture to a frameBuffer Object in OpenGL. Is it possible Thank you. As I mentioned it is true that GL_EXT_framebuffer_object specifies that 3D textures are valid targets but I am not aware of any vendors which are actually implementing this. Your only option for working with 3D render targets as I see it is DirectX 10. Which is avaliable, and there actually cards out on the marked which does support DirectX 10. ...Show All

• SQL Server Relationships

  Is it possible to have 2 different databases and create relationships inbetween the two I am thinking about way down the road and the size of the databases and I believe that I need to split my data into multiple databases to keep from running into the size limitations. Davids Learning By "relationship" , do you mean "foreign key" If so , the answer is "No, you cannot create a foriegn key relationship across databases." What you can do though to implement the same functionality is to create a triggers on both tables that enforce the "relationship" . CREATE TRIGGER MyTrigger ON dbo . ChildTable AFTER INSERT , UPDATE AS IF EXISTS ( SELECT * FROM OtherD ...Show All

• Visual Studio Trying to get client parameter values on the server

  I cannot seem to do the following: 1) I have a report that uses the ASP.NET 2.0 Report Viewer against a RS2005 report that has parameters. Some have default values. One is a text box. Others are drop-down lists. 2) I have ShowParameterPrompts = true and am presented the parameter area upon first visit to the page. 3) I fill in the parameters on the web browser page and click the View Report button 4) Now, on the server side, I want to examine the parameter values (in the Page_Load event). When I do a GetParameters on the ServerReport of the ReportViewer, I receive back a collection of the default parameters values, not the values that I just submitted. 5) The report is working just fine. How do I see the parameter values submitted b ...Show All

• Architecture don to not use "Inheritance"

  Have anyone try to design with no Inheritance at all I think *Inheritance* is not good as we think. It's force us to somthing we don't need, It's ok in some cases that better to be solved with no need to it. what do you think regards, dotHuman. Inheritance has its place. It is a powerful tool but it is relativly hard to get right - I usually have a a very shallow inheritance tree (Interface inheritance, on the other hand is easier) The main problem is that many people are not aware of Liskov's substitution prinicple (see http://www.ddj.com/blog/architectblog/archives/2006/08/liskov_substitu.html ) and they create sub-classes that are awakward to use and maintain Arnon ...Show All

• SQL Server Equivalent of Crystal Reports "Specified Group"

  I was just wondering if you could create in SSRS the equivalent of a Crystal "Specified Grouping" i.e. Let's say I have a Loan Risk Grade Field, and the values may be 1 to 99 If I wanted to group not by individual Risk Grade but say a grade banding how would I go about it In Crystal you would be able to create a specified grouping,let's say Group A = Risk grade 1-10 Group B = Risk Grades 11-20 Group C = Risk Grades 21 - 99 In SSRS, would I have to put this in the SQL (i.e. create a "grade banding" field output) or is there a way via the "Edit Group" or some other interface to specify this Use custom code. Something like: public function GetRiskGroup(riskGrade as integer) as stri ...Show All
