• Game Technologies: DirectX, XNA, XACT, etc. low fps

  i'm confused about fps in my programme. i draw 200 textured triangles in 640x480 window but get only approximately 160 fps. it's strange but when i zoom out from triangles fps growth momentally, but when i close... PreferMultiSampling = false ; SynchronizeWithVerticalRetrace = false ; RenderState.DepthBufferWriteEnable = false ; (i need it coz, ill render triangles with transparent textures) i use DrawIndexPrimitives, i.e. useing vertex and index buffer. any ideas how to increase fps No, i mean, that sounds too much. If the program is completely error-free and there really is a constant system overhead of 4-6 milliseconds, no application will ever run faster than 160-250 fps. It seems more likely the ...Show All

• Windows Forms creating a dataview

  I need to take a look at the content of some DataTable(s) I download from SQL Server in a purely debug situation. I decided to use DataView object for it. I improvised the following code: DataViewManager mng = new DataViewManager ( sqlDatSet ); DataView dtview = mng.CreateDataView ( sqlDatSet.Tables[jj] ); dtview.BeginInit ( ); The jj integer is the index of a particular DataTable in a DataSet and is found in a for loop. I expected a primitive form with a Table View displayng my records to show up. Is it not a reasonable expectation Nothing like this happened. The DataView remained an internal object. If I cannot get a good look at what is present in the tables I download I will be facing a cumbersome task of printing the stuff ou ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. GSE - IDE Problem

  Installed VC# Exp and GSE on Dell XP SP2 already satisfactorily running VS2005... Can create and run WinApps with no problems...however when I create a WinGame, the project files (.sln, .cs, etc) get created, Game1.cs displays in the VC# IDE, but Solution Explorer is blank(-contains no project tree)...can compile and run empty project....however if I click on Game1.cs, VC# IDE craps out with a "VC# has encountered problem and has to close' dialog box. Downloaded an XNA project off a web site and experienced screwy results when I loaded it...loads, compiles, runs OK but nothing displayed in Solution Explorer....however, can load individual files and navigate thru or modify them without IDE crapping out...

• .NET Development Bit confused about CTS ...

  Hi, After I have read several articles on msdn and other tech sites, I am now bogged now with a doubt. Is CTS a specification checked by CLR or a component in CLR I read all about the goals of CTS. But inside the .NET framework how it is placed Is it defined as a set of rules inside CLR, hence can I take it is a component Or is the CLR programmed to check the some specifications( which we call CTS) while executing a CLR compliant language Please explain me to get more insight in to this. Thanks, mani Probably the best way to think about is: the CTS spec came first. The CLR spec came next, built upon the CTS spec. The most obvious sign of this are the various flavors of IL opcodes th ...Show All

• Visual C# C# code snippets - Auto update?

  Is this functionality supported by any chance Thanks. I have a code snippet which is use in various files. If I insert the snippet but then make additional changes to the snippet, is there any way to automatically update the code files or do I just go back to each file and re-insert the updated snippet manually No, code snippets do not provide this sort of functionality. Though, you could possibly write a macro to automatically update your code files. -Tom Meschter Software Dev, Visual C# IDE ...Show All

• Software Development for Windows Vista Shared User Data Location

  What is Microsoft's recommended folder location for sharing files among users (so all have the ability to create, modify, and save files) There seems to be two possible places: * CommonAppData => C:\Program Data\[company]\[App Name]\ * Public=> C:\Users\Public\ The problem with [CommonAppData] is that it is a hidden folder so it is not a user-friendly path. The files that will be stored are intended to be browsed, opened, and saved, by all users. Also, does it break Vista's guidelines to have a shared folder with full control granted to everyone in the C:\ProgramData folder [Public] seems like a good place but I haven't found much documentation on its intended use. Also, using Install Shield, [Public] is not a defined location, so ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Fps is at ~60 all the time?

  Hello, I'm total noob with XNA so please bear with me :) In xna beta 2, designer is now gone, so to access IsFixedTimeStep I have to do this in code: public Game1() { graphics = new GraphicsDeviceManager(this); content = new ContentManager(Services); this.IsFixedTimeStep = false; } Problem is that it always shows fps at around 60 no matter what I do - draw some 3d model or just empty screen. I know I'm missing something simple here, please help.. Btw, I'm using one of fps code examples found on this forum, so I don't think problem is in fps code itself. Thanks, ErnisJ IsFixedTimeStep determines whether or not the Update call is made every Xth of a second or run continuously. What ...Show All

• SQL Server C# and SQL Express

  hi Y'All! I've been having quite some fun doing C#, im doing an accounting system just for the fun of it. I find C# quite user friendly (though Im using the express edition). Its not really that cryptic. Though one must be able to grasp the concept of OOP. Well, enough praise about the language, I know i wont get any freebie anyway. Just some question though. 1. Im planning to use SQL Server express as backend, right now Im using firebird and plan to change backend. What are the limitations of SQL Express edition like can I use it in providing for example a network of 10 users with an accounting application. 2. I plan later to create a C# program (windows application) that will access a database for example in the internet, the da ...Show All
