• Game Technologies: DirectX, XNA, XACT, etc. 3rd Series of 3D XNA Tutorials finished: HLSL intro

  Hi all- This 3rd series of XNA Tutorials was already online this weekend, I checked once more to make sure all code on the site compiles without errors. This 3rd series was written to be a introduction to HLSL, starting from zero, and consists of 18 chapters. The first chapter actually shows no code, it only positions HLSL in the big picture. For this series, I've chosen to create a scene shadowed by the Shadow Map algorithm to introduce the various concepts of HLSL. As you can see in the outline of this series, we start with basic chapters, which increase in difficulty throughout the series: Creating your own vertex format Creating a first vertex shader   and pixel shader, and playing around wi ...Show All

• Visual Studio Team System CTP6 - Cannot create project

  I've just installed CTP6 and cannot create a 2005 project. I am getting the following error: "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections".

• SharePoint Products and Technologies Persistent Sharepoint Server Error Events

  Hi - I'm running Sharepoint Services 3.0 and am seeing 3 different errors logged every single minute - IDs 6398, 7076, and 6482. Searches on these IDs have shown that other users are seeing them for different reasons. They all have to do with a "lack of storage" somewhere.

• Visual C++ COM/ATL App Method Return/Pass defined types

  Alright, I am not by any means an expert C++ programmer, so please bare with me. I have created a com object that will be implemented within C#, the reason for this com object is to create a persistent object of another library. My situation is this. I have the complete com object created, but would like to add additional supporting features, i.e.: An object that is defined within the C++ com object, such as a struct containing an int, a wchar_t*, and a boolean value. I would like to be able to utilize the object type from within C# to store the object rather than have a new object type in C#. I have seen this done in many cases, but just have no clue where to find such direction for supporting this. I would also like the come objec ...Show All

• SQL Server CLR vs T-SQL

  Hi, I bought Pro ADO.NET2.0 but could not find a clear description of the optimum use-case for CLR and T-SQL Stored Procedures in general. (although the book is great) It seems for complex or recursive tasks CLR SP is useful. But would you recommend using CLR SP for basic INSERT, UPDATE, DELETE, SELECT queries Thanks, Bahadir ...very common question these days. Simple answer lies in the fact that let the each person(in this case CLR/T-SQL engines) do what it knows best! Say for e.g. if you have lot many string manipulation activities to be accomplished. Now of course, in such a case writing a T-SQL UDF or a SP won't help much in performance gains. On all grounds for such activities, the CLR would ...Show All

  Hi! I have this legacy app in C++ and would like to put WCF atop of it. (in C++/CLI) I already managed to create a rudimentary service, but fail to use the DataContract attribute. Is this not possible in C++/CLI Thanks, Bernd Hi Ben! What I'm trying to say, but failed to do so, is that when writing something like this: [DataContract] ref class MyArray { ... } I get: error C2337: 'DataContract' : attribute not found My question is: Why does the compiler not recognize this attribute Thank you ...Show All

  Hi there, I'm "still" using TFS Beta 3 Refresh (It's not easy to talk/get TFS RTM version here in Portugal, since reseallers don't know it yet).

• Silverlight (formerly WPF/E) Symbols support?

  Currently SVG supports symbols ("defs") - complex elements that are described once and can be referenced and displayed many times throughout the code (tree). This saves a lot of byte-size for the files being used. Is there a similar feature in WPF/E Hi Barak, That works perfectly for elements created on the front end, but if I have a web service assembling the XAML on the back end, I would be concerned with the bandwidth required by the larger files, especially if there are hundreds of identical symbols involved. ...Show All

• SQL Server How to reset all tables ownership programmatically through a sp

  Before in SQL 200 I was using this script to do it, even if the change to Ad hoc updates to system catalog weren't allowed: USE Rouyn_Noranda PRINT 'Section 5: Resetting Objects ownership ...' GO update sysobjects set uid=1 where xtype = 'U' PRINT '***** Section 5 completed *****' PRINT '' GO In SQL 2005 change to the catalog are not permitted, is there a way to reset the ownership of all table from a database. Thanks, Stanley Please don't modify system tables directly. You cannot do that in SQL Server 2005 and even if you figure out a way, you will rely on a behavior that is not documented. So your code can break any time due to change in the server in a hotfix or service pack or major release. We can and will make chang ...Show All

• Visual Basic Reusing Forms

  Greetings I am converting a VB6 program containing multiple forms into a 2005.net VB program. In the old VB6 program I use a modal form and then I want to re-use the same form but but change some of the labels and make visible a control that was invisible the first time around. In the VB 6 version I was in, say, Form1 and executed the following code: Unload Form1 Form1.Show 1 This re-did the Load event and I used a counter to customize the form in its second life. Is there any way to do this simply in VS2005 VB I think you got it buddy! you are pretty much right on about the whole creating the instance of the form etc... yes, you can use Me.Close() to close the form and dispose of the ob ...Show All
