• Game Technologies: DirectX, XNA, XACT, etc. Power of XBOX360 - raw triangle power

  Hi, I was wondering if it was possible to compare the graphics power of XBOX360 to any of current gfx cards. Say, if it`s capable of rendering same amount of triangles as e.g. GF6800 does. The old XBOX was usually compared to GF3 in terms of graphics performance. The reason I ask is, that I would like to know the general boundaries of the raw gfx power, since I`m planning on converting some of my current games to XNA (and later to XBOX360) as soon as it becomes available. Currently I`m pushing the GF6800 card to its limits, which means I`m rendering a range of 0.5M-1.0M triangles (all unique, non-instanced) per frame and it seems that GF6800 starts to slow down when it crosses 1M barrier. No pixel shaders there, just Vertex Shader ...Show All

• Visual C# Visual Studio 2005 Professional crashes Vista Ultimate

  A couple of weeks ago I did an in-place upgrade of Vista Business to Vista Ultimate and ever since I've been experiencing blue screen crashes of my entire machine. Lately I've been looking at the memory.dmp file Windows generates and Windbg implicates Visual Studio a lot. It actually indicates a hardware problem but I never had problems with my machine while I was using Vista Business so I think reports of a hardware failure may not be correct. In any case, Visual Studio crashes a lot (just the program, not my machine) so I tend to think it's Visual Studio crashing my machine. Any known issues with Visual Studio and Vista Ultimate Just to note I am using Service Pack 1 and the Visual Studio Vista upgrade beta. ...Show All

• .NET Development How to Close Connection When Using Data Reader

  In a Windows app, C#, VS 2005 I have a generic class which opens and returns a data reader to the calling class where the data is processed. The generic class, get DataReader, opens a connection and generates the reader as follows: cn = new SqlConnection(strConn); cmd = new SqlCommand(strSQL, cn); cn.Open(); dr = cmd.ExecuteReader(CommandBehavior.CloseConnection); In the calling class, after the data is processed, I have no way to close the connection cn, and the CommandBehavior.CloseConnection parameter does not seem to close it either. I have Max Pool Size = 3 in the connection string, and I get a timout error when I try to open the data reader the fourth time. The calling class's code is: dr = sqlClass.getDataReader(strSQL); ...Show All

• Visual Basic Window size when using multiple monitors

  I have a Matrox Parahielia 3 monitor video card. Whenever I open a new window in the IDE it stretches it across all three screens. Is there a way to make the windows open onto the center screen at a certain size in a certain position for any new window so I don't have to resize every window to work with them Thanks I am having the problem while writing code in the IDE and not when the application is running. I can position windows in the application with no problem. When I open say the locals window it covers the full three screens and I have to resize it down to be able to work with it otherwise it is under all of the other windows I have open. Tim ...Show All

• Software Development for Windows Vista STANDBY power broadcast

  Hi, I am working on interrupting the standby and hibernate of Windows Vista and am handling WM_POWERBROADCAST. I found that in XP the hibernate/standby msg parameter is PBT_APMQUERYSTANDBY while in vista it is now something else. can someone point me as to what the value changed to I cannot allow the machine to go into hibernate or standby. Aborting a hibernate might not be in the best interests of a user. I have my notebook set to hibernate when the battery is low (yes I still have a notebook that gets a respectable battery life). I constantly have half-composed blog entries, forum postings and interesting websites open that I would like not to lose should my battery die while I'm attending to life. That being said, I'd prefer ...Show All
