• SQL Server Creating a Primary Key

  I have a table called 'RepCust' consisting of just under 1.5 million rows. I need to create a primary key based on the first six columns. Of these, the first colum is SmallInt, the next three are strings and the final two are SmallInt. If I modify the table in SQL Server Management Studio to add the primary key, after a delay in which it appears to be modifying the table, I get the message: 'Repcust' table - Unable to create index 'PK_Repcust'. Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. Any suggestions, please Rodney Jones SSMS has a very short lock timeout period.  Try ...Show All

• Visual Studio 2008 (Pre-release) XBAP photo directory access

  I have a collection of photos, say 500, in various directories on my hard disk. The user selects a directory, say 'directoryA', and I get a collection of photos from that directory using the following snippet: foreach (FileInfo f in directoryA.GetFiles("*.png")) Add(new Photo(f.FullName)); It all works fine when I run the application in VC#2005 but it fails in XBAP Browser mode due to 'System.Security.Permissions.FileIOPermission'. I can't find any sample where an XBAP accesses a directory or even just gets images. I understand that a 'Pack URI' for each photo might work but in this case I only have a directory name and then I look up the photos. I suppose I could look up the photo name in an xml file but I'm not re ...Show All

"open symmetric keys" is not allowed in a function if I want to encrypt a string in a function by sql2005's internal functions ,how can I do As the error message indicates, OPEN SYMMETRIC KEY is an operation with a side effect (i.e. it affects the current session’s key ring) and user defined functions (UDFs) cannot have such operations in the body.

• Game Technologies: DirectX, XNA, XACT, etc. A couple more questions

  Does the Xna Framework support bump maps for the 3D models In the tutorial, we create a view of sorts using: matrixView = Matrix .CreateLookAt(camPosition, Vector3 .Zero, Vector3 .Up); matrixPosition = Matrix .CreatePerspectiveFieldOfView( MathHelper .ToRadians(4 5.0f ), aspectRatio, 1.0f , 20000.0f ); and later on: effect.World = Matrix .CreateRotationY(modelRotation) * mesh.ParentBone.Transform * Matrix .CreateTranslation(modelPosition); effect.View = matrixView; effect.Projection = matrixPosition; What I'm trying to understand is what these matrices are for. What's the difference between a View matrix and a Projection matrix I assume the World matrix is where the mesh is in the game world. I'v ...Show All

• Visual Studio 2008 (Pre-release) Extensibility of entity model

  Hi, I'm building a generic framework. A goal of this framework is to be adaptable to several domains. So, I have some entities (almost the same in all domains) and a set of interfaces that I'll implement in specific entities for each domain. Entities contain references to interfaces Is it possible with ado.net vnext to create a sort of "abstract" entity model available to solve a class of problems I mean a model made up of "well defined" entities and other "abstract" entities. Should I create a project which contains a base entity model and redefine it in specific domain-driven projects Obviously, the framework should be unlinked from database structure.

• Visual Studio 2008 (Pre-release) DLinq Designer and class inheritance

  I've got a table set up for class inheritance, as discussed in the DLinq Overview for C# Developers. Now I can't figure out how to get DLinq Designer to generate the different classes for me. I've got a Contact table with a DiscKey varchar(1). When 'C', it's a company. When 'P', it's a person. So I should have a Contact class, a Company class, and a Person class, where Company and Person derive from Contact. I haven't been able to figure out how to get the DLinq Designer to do this.
