• Game Technologies: DirectX, XNA, XACT, etc. XNA URLs

  Just wanted to let whomever it might concern that there are a few bum URLs lying around in the XNAosphere. well, I've got two so far, but they seem to be pretty important ones :-) 1. The confirmation email I got from xblive on my club sub purchase gave me this URL -- http://msdn.com/xna/creators 2. The article " Xna Game Studio Express > Programming Guide > Audio > Audio Overview " has a link to: http://msdn.microsoft.com/library/ url=/library/en-us/directx9_c/audio_xact_authoring_intro.asp Both of these result in a 404 ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Algorithmic Challenge

  what is the best way to "download" a matrix into the gpu (integer values 0-255) apply an affine transformation to it (rotate stretch etc) and read it back. i have no knowledge of graphic programming , but i want to move some of the number-crunching from the cpu to the gpu, and this simple task of rotating and stretching a BW image seems like an easy thing to accomplish on the gpu. by the way i would appriciate a solution in c# since it is easier for me to read but c++ is also acceptable. o.k thats it for now help me out and be rewarded with genuine heartfelt thanks.. peace out long live the revolution You might want to look into the www.gpgpu.org website - the use of GPU's for number crunching i ...Show All

• Visual Studio Express Editions Correct way to read plain text file

  Hello, I am trying to read plain text file. Although there are multiple methods in .NET framework to do this, I cannot get correct result. First I tried with ReadToEnd() method. This method doesn't detect new lines in "unix" type text files (the ones that have only decimal 010 for new line (windows text files have 013 010)). Code looked like this: StreamReader sr = new StreamReader (openFileDialog1.FileName); txtBox.Text = sr.ReadToEnd(); Then I tried to do this some other ways that were all similar to this one: using ( StreamReader sr = File .OpenText(openFileDialog1.FileName)) { System.Collections.

• Visual C++ double to decimal representation - more digits than necessary are produced

  Hello everybody... I've got a question that has been making me suffer unberable pain recently, and it concerns the following snippet: double x = 8517.44; printf("%.25G\n",x); The printed result is 8517.4400000000005. Ok, internally, the number is represented as 1.0397265625000000621724893790087662637233734130859375 x 2^13 = 8517.440000000000509317032992839813232421875 When converting that number to string, how does VC++ decide how many decimal digits to produce I'd expect a reasoning in the lines of : "Representing 8517 requires 14 binary digits. An IEEE double has 53 binary digits precision, so 40 binary digits remain for the fractional part, or 2^40 different possibilites. However, 10^11 < 2^40 < 10^12, so 12 decimal di ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Online Gaming Xbox/PC Interoperability?

  Will we eventually see a point where Xbox and PC gamers will be able to play the same games online with each other I admit, this is probably tough for a FPS. But turned based strategy games should be doable right now. It would be neat to have a whole, who's smarter, Xbox gamers or PCgamers strategy game competition Barring a bug in the CLR for the X-box, that seems unlikely. That's why it's a managed framework -- they control the execution environment, and you cannot run untrusted code. Thus, I would expect any unmanaged code libraries, P/Invoke, etc would also not be supported on XBox 360. ...Show All

• SQL Server SQL Server Logs - big and unopenable

  For whatever reason the SQL Server Logs (found under Management|SQL Server Logs) are fairly large. 'Current' right now is 52.606.607bytes in size, older ones are .

• Game Technologies: DirectX, XNA, XACT, etc. SpaceWars - can you work around Shader limitations?

  Two days ago I started working on the XNA framework. This is also the first time I've had any dealings with C# or DirectX. I got the first game tutorial working pretty easily, but I couldn't get the SpaceWars starter kit to run properly. Firstly, I had to set AllowMultiSampling to false (this is a known, and widely discussed problem), and also switch to keyboard mode. With this done, the game ran, but I could not see some of the graphics (ships, backdrop & bullets) in either retro or evolved mode. Score and explosions appeared ok. As far as I can tell, this is because the missing graphics are using CompiledEffect shader objects which are loaded from the FX files. My poor graphics card (Nvidia GeForce 440MX) doesn't support any shader ...Show All

• Windows Live Developer Forums Popups for pushpins have wrong Y coord in Firefox

  Not doing anything fancy - just supplying some text to popup for a bunch of pushpins. Location of popup is fine in IE, but in Firefox the y coord discrepancy gets worse the larger the y-pixel value of the pushpin is in the map. Anyone know of a workaround Could be a grapic card/monitor issue that your referring to.  I've tried to re-duplicate it on my browser (IE and FF 1.5) but to no avail I can't seem to see this issue.  I know that having VE on high resolution computers causes some functions to fail (such as pixeltolatlong) but it seems to work okay for me on 1280 x 1024 resolution. ...Show All

• SQL Server Shrinking databases or files

  Hi, I have some doubts about Shrinking databases or files. while shrinking a file, I learned that we are alllowed to shrink more than the minimum size of the file, does not it bring damage to the data in that file I also would like to ask something abou th following: Most databases require some free space to be available for regular day-to-day operations. If you shrink a database repeatedly and notice that the database size grows again, this indicates that the space that was shrunk is required for regular operations. In these cases, repeatedly shrinking the database is a wasted operation. Can anyone give an example about this regular day-to-day operations Thanks ...Show All
