• Game Technologies: DirectX, XNA, XACT, etc. Custom vertex format

  I am writing a pixelshader for terrain coloring and I am selecting my coor based on a number of different parameters, such a normal vector, 3d position and up to four noise functions, which define things as humidity, terrain type etc. The terrain is one huge mesh, optimized as a ROAM, and each vertex has the properties mentioned above. There are formsts for storing normal, position, color or some other combination, but there are not enough for my need. I remember reading somewhere about defining your own format, but I can not find it again and the last time i tried, it didnt work. Can someone suggest where I should read about this An extra question is... the position is never interpolated (before being passed to the pixelshader ...Show All

• Visual Basic Backgroundworker component cross-thread operation error

  Cross-thread operation not valid: Control 'PanelContainer' accessed from a thread other than the thread it was created on. Here is what led up to this. My Mainform Load event is instantiating a dozen user controls and adding them to a panel collection for use later in the application. There are so many controls on the Main Form now that there is a paint problem...It takes 2-3 seconds now to get through all the initializations...and various controls are shown in different states of being painted..some are even transparent and show the desktop. Thinks look pretty ugly for a couple of seconds. I thought I would have controls be loaded asynchronously, after the initial controls are loaded. PanelContainer is declared/instantiate ...Show All

• Visual C++ Calculating the angle of an arc in a cartesien grid

• Game Technologies: DirectX, XNA, XACT, etc. How do you implement Fog into a scene?

  Hi All, I have finally got some 3D up and running so things are whizzing about (which is always fun to watch... for a while, yeah I know, small things...) and I was wondering if anyone had any examples of putting fog into a scene. I tried last night and succeeded in turning all my meshes to white, not matter how far away they were from the camera. No matter what I did to the values, nothing changed. As always, any help is greatly appreciated. Cheers Okay, so I now have fog in the distance but have something strange with it. I set my FogColor to 128,128,128 and my background color to 128,128,128 but when the meshes appear in the distance, they are bright white. The only way I can get things to fade in, is to have the ba ...Show All

• Visual Studio 2008 (Pre-release) Using IXmlSerializable objects for data transfer in Service Contract

  Hello, I am trying to implement a WCF Service that uses System.Windows.Annotations.Annotation objects as parameters of some operations. The system.Windows.Annotation type implements IXmlSerializable, but its IXm lSerializable.GetSchema() implementation always returns null. When i try to generate the metadata files for my service using svcutil.exe i get this error: The 'http://www.w3.og/2001/XMLSchema:schema' element is not declared. Despite this message all the files are generated, but system.Windows.Annotations.xsd looks odd and so is the client code that svcutil.exe generates for my service. My question is: Is it possible to use IXmlSerializable object that does not implement IXmlSerializable.GetSchema() for data transfer and is ...Show All

• Visual Studio Accessing properties of the current/executing project from task

  Hello, I would like to access the properties set in for a build / an execution from within a task. My idea is to create a task that can take a template text and fill in any $(..) with the appropriate property value. The goal is to allow simple creation of templates that may access version properties, solutionname, productname / target assembly name, etc. The end goal is a BOM statement for a build of a solution. Answer to the issue of accessing properties or other ideas appreciated! Best regards! I would like to access the properties set in for a build / an execution from within a task.

• Visual Basic Label for a Context Menu TextBox

  Hi, I have a context menu that has a textbox on it to accept a string from the user to name an item they right-click. Nice so far. My problem is that the box sits there with no indication as to what it is, I can not find a way to put a label in front of it to indicate its content. Added an item with a fly-out and put the box there but do not feel this is satisfactory. Is there a method to put a label in front of the textbox You could create a custom user control which is just a label next to a textbox and use that. Or, just put the descriptive text in the text box and make it disappear when the textbox is clicked on. Matt ...Show All

• Visual Studio Tools for Office Infopath Automation

  Hello, Please accept my apologies if this post is in the wrong forum. I checked around and believe this is the correct place to post. If not please advise and i will promptly move. I am currently using an infopath solution for data collection. The forums contain a number of dropdown lists that need to be populated at run time. Unfortunately, a requirement exists that specifies that the infopath forms must function in a disconnected manner (not my idea!!). So that pretty much excludes all the sharepoint lists / webservice / dataset examples i have seen. I would like to know if it is possible to populate the infopath form controls using automation. IE: //Create an infopath application object //Open an infopath form / template //Obtain ...Show All

• SQL Server Trying to return whole records with distinct fields

  Hi I am trying to write a query that will return a full record with a particular distinct field (the rest of the record being the first such record that includes the distinct field). For example, for the following: Fruit Like Colour Apple Y Green Orange N Orange Banana Y Yellow Grape Y Green Grapefruit N Yellow I would want to return (assuming Colour was the distinct field): Fruit Like Colour Apple Y Green Orange N Orange Banana Y Yellow How do I do this I've tried using a join (of all different kinds) with a subquery that uses SELECT DISTINCT but this doesn't seem to work.

• Visual Studio Team System tests as a work item

  We're struggling between whether to choose tests as a work product (built into visual studio) or as a work item (customized work item). We're doing purely 'manual' tests, so we don't need to consider unit / load / web tests. my thought is to make them a work PRODUCT, this would give us some flexibility in the future, but here are my problems: how do i find out what tests to run, how they relate to requirements, bugs, etc -- i know i can attach a test to a bug (and therefore any work item through the test field) but how could i attach multiple tests to a bug / requirement similarly, how can i report on that requirement to find out if all tests have been run for it This seems easier to do with a test work item. also, is that really what th ...Show All
