• Game Technologies: DirectX, XNA, XACT, etc. Solved: Using a Quaternion and Vector to construct a camera view matrix

  I am trying to create a camera class that uses a quaternion (orientation) and a vector (position).  When I set the view matrix, I am not using Matrix.LookAtLH.  Everything works pretty well, except that I cannot get the camera to rotate on its own axis (i.e. at its current position).  It always rotates around the origin.  My test app has a textured sphere and when I rotate, it is always at the center of the screen.  I did some extensive searching through these forums and saw the problem mentioned several times with no real solution, I also searched the web for roughly 2 hours looking for code that either does this, or builds a left handed perspective matrix so I could compare my results with that.  This is my ...Show All

• Visual Studio Team System Check-out not getting latest (RTM)

  Hi all We have this occasional problem whereby checking out a file doesn't get the latest, subsequently resulting in us having to merge our changes due to the file being different on TFS. Any ideas This sounds like it could be a bug to me Thanks Kev (dunno how this got posted to the wrong thread) Get Latest on Checkout is unlikely to be in SP1.

But I just want to be able to display a crystal report i've created already within my application. most of the help online revolves around the professional versions crystal features so I've been having trouble getting my report to display.

• Visual Studio 2008 (Pre-release) Mapping to the "varchar" field?

  What is the correct mapping to the database table with "varchar" field type The vNext wizard mapped it like this: <Property Name="GUID" Type="varchar" Nullable="false" MaxLength="60" /> Everything compiles fine, but at runtime it raises error, complaining that varchar and nvarchar are not compatible. If I modify mapping manually to look like this <Property Name="GUID" Type="nvarchar" Nullable="false" MaxLength="60" /> everything compiles and works OK, but then I do not understand where is the magic of converting unicode to non-unicode chars happens and what is the downside of this fix Alex Atul Adya - ...Show All

• SQL Server Calendar Control issues

  Hi all, When I click on a calendar control for date parameters the page will freeze or throw a java script error. This does not happen all the time, and is not isolated to one PC. It happens randomly on several PCs. Is there any known issue with this control regards, Bill I am just hoping that some sort of hot fix is available soon. Like I said though, it does not work at all with IE7 so if MS is planning to release IE7 as a critical update like it is rumored, it will break all RS sites. ...Show All

• Software Development for Windows Vista Cannot use EventDrivenActivity in a sequential workflow!

  Hi MSDN Documentation at the following link denotes that we can have EventDrivenActivity in a sequential workflow: http://msdn2.microsoft.com/en-us/library/ms734657.aspx It tried to use it in Sequential workflow and the IDE doesna€ t allow mw to drop an EventDrivenActivity in a sequential activity. Am I missing something Any help would be appreciated, Alan Alan, you can't directly add an EventDrivenActivity to a sequential workflow. You must first drop a ListenActivity onto the workflow, and then add the EventDrivenActivity to the ListenActivity. See this MSDN link for more info.

• Visual J# Migrating JNI to P/Invoke

  Hi guys, I'm attempting to migrate a Java application to the .NET framework. This Java application uses some C++ code to provide functionality not present in either the Java framework library or the .NET framework. Java makes these calls via Java's JNI technology. For example: // The C++ code: JNIEXPORT jint JNICALL Java_xyzMedia_util_MyControl__1getSpectrumLength(JNIEnv *env, jclass jcl) { ... } // The Java code that calls the native method: native static int _getSpectrumLength(); How do I call this function using .NET's P/Invoke technology You can write JNI code in .NET and use you Java legacy.
