• Game Technologies: DirectX, XNA, XACT, etc. XNA/Xbox 360 memory management heads-up...

  I was just browsing through some docs on the 360's heap manager, and it turns out it is a compacting mark and sweep collector rather than the generational model used on the desktop... So... what's the deal regarding: Large block allocation (will it have a large object heap like the desktop version ) GC pauses times (do all threads halt during GC) Rico Mariani recommends a heap size equivalent to the Gen 0 size on the desktop, i.e. ~cache size. That seems way too small unless we are dumping lots of game data into unmanaged memory! Andy. You're right about the sandboxing, just not about the details of how that works. It turned out that it was possible for us to support unsafe code and pointers even insid ...Show All

• SQL Server olap and hierarchy problem

  Hi. This is an OLAP question. I have a dimension which is a father-son dimension. I built the cube in analysis server. In the analysis browser I can see the dimension fine, I hant my reporting services report to show that dimension. The problem is that the report won't show me that dimension in hierarchy tree (even if I check drill down) but flatten it down. Does some one know if report service can handle those kind of reports Thanks. Hi Teo, Thanks for your replay, Its hard to find help and support for Olap and for Olap and SSRS on the net. Its very disappointing to hear that RS does not support OLAP (and for me, if it can't handle parent-child dimension it can't handle olap). Looks like we will have to ...Show All

• .NET Development .NET development 2.0 = 32bit ?

  Hi, I'm confused. .NET development 2.0 only runs on 32 bit .NET development 2.0 SDK runs on 64bit but needs the other version to install. This doesn't makes sense. I'm SOL I guess. hi , i didnt get ur question , .net 2.0 runs fine (AFAIK) on 64 bit machines, currently we are doing all our developemnt on 64 bit environment, we have dual core p4 x64 architecutre ,with 64bit windows xp professional, vs2005 and .net2.0. .net 2.0 provides separat command shell for 64 bit and 32bit command prompt, 64 bit runtime distributable are also available, You might run into problems where u are referencing 32 bit dll/exes, cause by default on x64 machines vs2005 generates 64 bit executables. 32 bit dlls/exe can not be loaded into a 64 bit process, d ...Show All

• Visual C# Error when trying to compile a program

  I am quite new to Visual C# 2005 Express and I sometimes get an error while trying to run my program (F5). It looks like this: "The following module was build either with optimizations enabled or without debug information: C:\Documents and Settings\CBS\My Documents\Visual Studio 2005\Projects\Lesson02\Lesson02\bin\Debug\Lesson02.exe To debug this module, change its project build configuration to debug mode.

• SQL Server First Time Installing - Can't Find BIDS

  Thank you to all that take the time to read this! All software is installed on a single development pc. I have a SQL Server 2000 Developer Edition Database that I am using to test a new Accounting System. SQL Server 2000 is the required format. I would like to start developing some SRSS reports against that database. It was suggested that I install the SQL Server 2005 Reporting Services, because I was told 2005 is less buggy and easier to use. I installed SRSS 2005, and only SRSS 2005, and used the Configuration Tool to get it configured properly, I think. I have green checks on everything except "Email Settings" and "Execution Account" Now, I want to write some reports. BIDS is not under the "Mi ...Show All

• Software Development for Windows Vista Designer Problems - The Exception...

  I’m experiencing some problems while working with wf in visual studio. Sometimes while building or rebuilding the solution, the build fails, and NO exceptions are given . Opening the workflow file (workflow.cs) will show an exception in the designer: “ Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information .” I don’t know what it means. However sometimes, restarting VS will resolve the problem, but then again…sometimes it doesn’t. The problem occurs for both state machine workflows and sequential ones. I’ve not used workflows with code separation. An other, not so funny feature is the fact that workflow files will be changed up on building. Using source control, files will be ch ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 2D rotation question

  These are probably pretty Noob questions but this is my first game ever. I'm looking for the XNA way of doing things for the following: 1. I have a sprite that is a simple rectangle. When I spriteBatch.Draw I rotate the sprite say 90 degrees. I have a bounding box that corresponds to the sprite which I also need to rotate so it matches what is drawn on the screen. Origin is (0,0) but I could make it the center of the sprite if that is easier. I'm guessing I have to use Matrix.CreateRotation (x,y,z ) then a Vector2.Transform This is the part I'm kind of confused on. 2. I want my enemy ship to face the player ship. I have the position of both objects. How do I calculate the angle between them 3. Calculate the distance between two points. ...Show All
