• Game Technologies: DirectX, XNA, XACT, etc. Heightmap Terrain Component

  I thought the whole component concept was pretty cool. So I threw together a quick heightmap terrain component. http://i9.photobucket.com/albums/a59/craigory666/heightMapTerrain.jpg http://i9.photobucket.com/albums/a59/craigory666/heightMapTerrain2.jpg http://i9.photobucket.com/albums/a59/craigory666/heightmapprop.jpg It should work with square .raw files, and for the effectPath I'm just using the default texture shader found in the help file. The view and projection matrices of the terrain are exposed, so you should be able to hook up whatever camera you have going and just update the terrains view, and projection matrices during your games update. using System; using System.Collections.Generic; using System.IO; using Microsoft.Xna.Fr ...Show All

• SQL Server Help needed?

  Hi I'm a newbie to SQL server..... l'm building a website where companies can save important data. I have a SQL server available but I'm not sure how to store the data. Should I create a new database for every user or should I store everything in the same database and then use a UserId to recognize the data and the user The data stored for each user are stored in tables which are exactly the same so all tables could be gathered into one table and then a UserId could tell which records belong to whom. Hope my english isn't too bad..otherwise just ask me questions and I'll get back A.S.A.P. Regards Joachim hi joachim, thats not a bad english at all. regarding your question i ...Show All

• SQL Server Black server reports after installing SP2

  After installing SQL Server 2005 SP2 all of our server reports are being rendered with a black background and white text, which needless to say is reversed of how they were being drawn before installing SP2. This only happens when the report viewer is displaying the report in “Print Layout” mode. Normal mode shows the report as expected. Has anyone else had this problem or suggest a solution Thanks in advance. It turned out that this is an issue introduced with SP2 that affects certain video cards. I am also experiencing the same problem but t never occurred to me that this could be actually a bug during the SP2 testing so I never reported it back . The RS team is reviewing currently this issue. Please ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Can Visual Studio 2005 create a Windows Game project(XNA) like Visual C# 2005 express

  Can Visual Studio 2005 create a "Windows Game" project(XNA) like Visual C# 2005 express How do I implement or modify some setting And See XNA MSDN in Visual Stduio 2005's MSDN. Well, if you mean if you can use the File-->New Project --> Windows Game template. No you can’t. That kind of extensions are only available in Visual C# Express. What you can do is reference the XNA dlls inside a Visual Studio 2005 project, and do it at your own. If you take a look at the Windows Game empty project, it only has a couple of files in it. Just copy the code generated to your VS2005 project. One thing you must be aware of: If you use VS2005 to develop XNA projects, you will not have access to the Vis ...Show All

• Smart Device Development Resource DLL still active

  Hi all, We made a .Net DLL that is the managed end of an unmanaged - managed bridge. There is nothing in the DLL besides the wrappers to the unmanaged function calls and the P/Invokes. When I terminate the program the managed DLL stays active. Any ideas on why it would stay in memory Do you have to terminate a managed DLL in some way Alex, Nope. Everything is a command-response call, no threads. I did notice that it's only when I am debugging and the debugger terminates in an abnormal fashion, like an uncaught exception. It does not seem to occur when I run the program outside of the debugger or the debugger terminates the app normally. ...Show All

• .NET Development long arrays blues

  Someone please correct me if I'm wrong, but after reading a few porting documents it seems to me that the .Net framework is trying to support a 64bit computing model essentially by doing the following: Making pointers 64 bit Allowing a long to be used as an array index as well as a length specifier during array creation I've seen several documents mention how it would be space inefficient to change the size of int along with the pointer size and I can understand this issue, however is this space optimization worth breaking *all* functions that take arrays as input My concern is that any function that accesses an array will not be able to utilize the 64 bit address space without rewriting it to use long indices.

• Visual C++ VCToolkit

  I just realized that VCtoolkit was removed from the downloads page. I was wondering if it was legal to include the setup file for the toolkit with my IDE for a game I'm working on since Microsoft no longer lists it. Any ideas I would really doubt but you can confirm by contacting support in your area. http://msdn.microsoft.com/library/default.asp url=/library/en-us/vsintro7/html/pssPsoverview.asp should contain more info. I would also not recommend depending on VC versions that don't have current official support. Thanks, Ayman Shoukry VC++ Team ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XACT files(xgs,xsb,xwb) don't deploy during Publish; getting FileNotFound

  My problem: My game project in XNA uses 2 sounds. I went thru the XACT tutorial(for my uses I found it quite easy to add my .wav files used via XACT), and I now have all code in place, and functioning. When I Start Debugging in XNA, my game runs correctly, and I get the correct audio plays when the proper events cue them up. HOWEVER, once I publish the same project, and install it from the Setup.exe, the installed game crashes. I get the error: system.io.filenotfoundexception. What I have checked already: 1.All 3 XACT files are in my main game directory. 2. All 3 are set to 'always copy' to output directory. 3. All references in the Sound.cs class I created point to the correct XACT files(the build would not run if it did ...Show All
