• Game Technologies: DirectX, XNA, XACT, etc. World to screen conversion.

  Hi. Something weird when trying to covert world to screen coordinates. Vector3 res = Vector3.Transform(worldPoint, Camera.View * Projection); I get the result vector with values greater than 1. Aren't the values post projection supposed to be clamped Both the view and projection matrices are valid (and are used to display on screen). Cheers I know it must be something stupid on my part but... Vector3 p = new Vector3(0, 10, -1500); Matrix proj = Matrix.CreatePerspectiveFieldOfView((float)Math.PI / 4, 800 / 600, 5f, 3000f); Matrix view = Matrix.CreateLookAt(new Vector3(0, 0, 20), Vector3.Zero, Vector3.Up); res = Vector3.Transform(p, view); res = Vector3.Transform(res , proj); What is res supposed to be Isn't it supposed to be [0, 1] ...Show All

• SQL Server Same effect as Cross Join?

  How can I achieve the same effect as a cross join (since the merge operator doesn't have a cross join) Situation is this... a flat file has some header and footer information that I need to keep and attach to each row. So for simplicity sake of an example lets just say header has only 1 thing we care about - a row that says DATE=01/01/06. I take the file and run a split to split into "Date" "Data" and "other" (other has all the throwaway rows in header and footer I don't care about). Then I use a derived column object to get all the columns out of the "Data". Finally I want to add that Date metadata back to every row in the data... I thought this would be an easy thing to do.. but I can't s ...Show All

• Visual Studio Tools for Office How to combine two ranges?

  Hi All Do you know any method that can combine two ranges Using following code I can't achieve this because COMException is raised with HRESULT 0x800A03EC: using Microsoft.Office.Interop.Excel; Range r = sht.get_Range( "B2,C3" , missing ); // faires COMException with HRESULT = 0x800A03EC: Steve Hansen wrote: Interesting. Perhaps it is something to do with the culture issue as even in a shared add-in I can use the technique without issue. OK, I changed my windows Regional settings to en-us (which is what Excel wants to have) and indeed, the syntax now works. So it is a problem with Culture Info, and apparently the approach described in the MSDN article doe ...Show All

• Visual Studio 2008 (Pre-release) using WPF in MTA applications

  My application runs in MTA thread. WPF needs STA, so I created a new STA thread that creates and shows a window. This works, but only one time.

• Visual C# timing and "scheduling"

  i have to write an application to do some stuff, firstly i need it to be "always on" and i need to be able to   have "schedules" in the application, every 20 minutes, once or twice a day at certain time etc....   i guess that using a windows service and utilising the system.threading.timer class would be the best way to go about this... are there any other, maybe better, ideas about how to tackle this A few issues spring to mind: You've got a race condition here - if you happen to schedule a job that's due to run almost as soon as it's scheduled, there's a chance the timer will fire in between you constructing the ScheduleJob and attaching the event handler. Two possible solu ...Show All

  I would like to create a map based on latitude and longitude coordinates that is on the highest zoom possible and contains all of the coordinates.

• Community Chat Native C++ cross thread call framework

  If you're a C++ developer, with an interest for threads and interlocking, I'd be greatful for any input (be it comments, suggestions, criticism) on a generic framework I've been working on. I wrote a quick article about it, and included full source code + examples at Codeproject: http://www.codeproject.com/useritems/threadsynch.asp . I find that not too many seem to share my passion for that specific subject, so by asking here, I hope some thoughts are presented (or perhaps provoked). The very reason for me to put the framework onto Codeproject, was to enhance it through feedback and collaboration with other devs. Anyway, as I said: all thoughts are welcome. Should I include some diagrams to better explain how the framework does it's ...Show All

• .NET Development WSE: Including a username with MutualCertificate11Assertion

  How can I propagate the user's identity when using MutualCertificate11Assertion I want to include it in the headers, signed so it cannot be changed. The user logs into web application which consumes a web service. I want the certificates for mutual authentication between web application and web service, and I want the username to be propagated to be able to do desicions in the web service depending on who the user is. While I understand how to add a new header, I can't make it work at the receiving end.

• Visual Basic Current Line Colored by IDE (VB.NET)?

  I was wondering if anyone knew a way to make it so that the line the cursor is currently on could have a different background color from all the other text. It greatly increases visibility and ease of use (anyone who has used a text editor like TextPad can attest to this being quite useful when you have huge nests and you want to, for instance, paste right at the line the cursor is on). I don't see any options in the IDE, but maybe someone has made a plug-in Thanks. Oh, I should note that I'm using VB.NET and VS 2005. ...Show All

• Visual Studio Team System Is there any configuration we need to do in VSTS to run the 64bit dll on 64bit OS?
