• Game Technologies: DirectX, XNA, XACT, etc. equivalent to the MDX function Matrix.Transformation

  Hi, What is the XNA equivalent to the MDX function Matrix.Transformation Thanks in advance! It doesn't currently exist in XNA. You will have to compose your own transformation by combining the Matrix.CreateScaling, Matrix.CreateTranslation and Matrix.CreateRotation methods. Maybe they will re-add that method since it's more efficient than creating all the transforms separately and then combining. ...Show All

• Visual C# multithreading and locking best practices

  Hello! Suppose I have an object (instance of my own class X) that is used by class A in AppDomain 1 and class B in AppDomain 2. These classes methods can be run in many different threads. Among properties of class X is a generic Dictionary object. I need to provide thread-safe access to this Dictionary (reading, writing and iterating over). I could create a wrapper class for the Dictionary with modified methods for changing its elements, and use locks there, but what about iterating over the collection using foreach loop If class A uses foreach, lock should be placed there, and locked object must be the same as in the wrapper class - that means visible outside class X. This can cause problems, as class B can lock the Dictionary in class X ...Show All

  Hi. I have a pivot table that works on all the records in a table. I want to apply a filter through VBA code as follows: DoCmd.OpenForm "fpvtAxisI", acFormPivotTable, , "[Part]='1a'" The filter doesn't seem to be working because all the records got displayed just as if there's no filter.

• Visual Studio 2008 (Pre-release) Render buttons without border

  Hello, I use some Buttons containing images in my application. The images are partially transparent. Everything works fine, the problem is that a small blue rectangle remains around the every single button. I already tried to set BorderThickness to 0,0,0,0 - without success, nothing changed. Is it possible to render buttons completely without border or do I have to create a custom control Thank you very much.

• Windows Forms Can't disable a button

  I am programming in c#. I have a button on my form that when clicked, it plays a wav file using the PlaySound method from winmm.dll. The wav is about 3 seconds long. The problem is that if I keep clicking the button during the 3 seconds the sound is playing, it queues all of the clicks, and plays the wav over and over. My Button is named btn. So I tried: this.btn.Enabled = false; PlaySound(...); this.btn.Enabled = true; Doing this successfully greyed out the button while the sound is playing, but it still accepts clicks, so it didn't fix my original problem. Is there some way to clear the event queue Or is there something else I'm doing wrong. I just want the button to not work while the sound is playing. I have also tried ...Show All

• Visual Studio 2008 (Pre-release) How to use constructors or methods of data object with WCF service

  I have some questions regading how to use of data object using WFC Service. For example I have an object called Student (see codes below), and property IsOver25 this is readOnly property. However, if I do not put set { ;}, it's won't compile . What I need to do here in order to get rid of set { ;} statement. Another problem is using contructors and methods of data object. Since we don't put [ServiceContract] on the data object, I could not use the override ToString() version of Student object on client side. So the question are: 1. What should I do in order to use the constructor of data object 2. What should I do in order to use the methods on data object ( will not many but somes) Regards, John dang using System; using Syste ...Show All

• Visual C++ hangman project

  Hello, I'm somewhat new to C++. I am taking a class on it in college, but the teacher doesnt like to explain things very well. Basically her idea of helping us learn C++ is this: "this is how you start all your programs in this class: #include <iostream> using namespace std; int main() { } " She never explainted even what "#include <iostream>" or "using namespace std;" ment. So, this brings us to my question. I'm trying to write a c++ program *for a project in class* that is a hang man game. The hangman is stored in a character array. The user is able to input a word into a 25 character array "char word[25];". There are a couple of things I need to do. the first thing is, I need to know h ...Show All

• Visual Studio Team System ACTUAL Expected Behavior of the <WHEN*>, <DEFAULT> and <COPY> Rules

  I am reading through Section 1.16 in the Authoring Work Item Types document and although it makes perfect sense I am not actually seeing this behavior. To quote from the documentation: 1) A user gestures to create a new work item or edit an existing work item. 2) Fill in field defaults. For all fields, use any <DEFAULT> rules which are outside <WHEN*> rules. 3) Copy field values. For all fields, use any <COPY> rules which are outside <WHEN*> clauses. 4) For all fields with a <WHEN> rule that matches first do <DEFAULT> then <COPY> rules inside. 5) For all fields with a <WHENNOT> rule that matches, first do <DEFAULT> then ...Show All

• Windows Forms How to record screen?

How do I access different windows from c#.net The window can be a webcam window of skype/yahoo or a windows media player playing a clip or the desktop !! Thanks Aseem Chiplonkar You could use "Windows Media Encoder SDK" to do that. This is a free tool offered by Microsoft. There is an executable in this package that will let you capture the screen when you wish to start and stop as a "Windows Media Video" file. There are plenty of other places that you can find tools to do the same thing... such as "Lead Tools". ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. FX Composer and DirectX Extensions for Maya (and Sas?)

  I am writing my effect files with FX Composer, it's a really helpful tool. I'd like my artists to be able to apply the various effects from within Maya 8. In another thread, someone very helpfully provided a Maya 8 version of the DirectX Extensions, but I am still encountering some difficulities. The documentation of the DirectX Extensions are extremely sparse and I can not seem to find any independant tutorials or anything on it. I'm beginning to wonder if anyone else really even uses the extensions and why or why not. In any case, I'm able to load an FX file and it shows the parameters, but I can not get any sort of binding to work. I've tried normal semantics, I tried a SasBindAddress annotation, and a few other things, but not ...Show All
