• Game Technologies: DirectX, XNA, XACT, etc. RTS Camera

  Hi, I've went through any XNA game component, tutorial or forum thread out there and still can't find an example for what I need. Maybe someone could enlighten me or point me in the right direction! Trying to create a basic RTS style camera. The thing is when doing composite rotations no matter which axis I feed to the Rotate() method, eventually "yaw" and "pitch" rotations composite into a "roll". I want to keep my camera's roll level with the XZ plane. I tried using both "world" and "camera" up and left vectors for this. Didn't work.

• Visual Studio SandCastle, Msbuild, and H2Reg

  I have updated to the Oct 17 version of sandcastle and update msbuild scripts for the changes in this version. I am successfully building an hxs and can view it correctly with h2 viewer. However, when I register the collection to integrate it with Vs 2005 only the index items appear but nothing shows in the content window.

• Smart Device Development Get rid of/disable X

  I'm developing an MFC app for a Pocket PC type device. Most of my dialogs were automaticly given an OK in the upper right corner that caused that dialog to close and I disabled it but replacing the void OnOK() function with one of my own. However the main window is given an X in the corner that causes the window to close (and dosn't even stop the program), i've tried replacing OnOK() OnCancel() OnClose() OnDestroy() without any sucess of intercepting/detecting when the user pressed the X. How can I do it OK, that didn't work for me either, compiler can't find WS_NONAVDONEBUTTON WM_WINDOWPOSCHANGED and WM_SIZE both get sent when the program loads but not when it smart minimizes. P.S. for those of you who a ...Show All

• Visual C++ Shallow Copy , Deep Copy , Memberwise Copy ,Bitwise copy

  hello ppl, i searched thru google but i didnt find the exact explanation for constructors. Shallow Copy , Deep Copy , Memberwise Copy ,Bitwise copy i got some conflicting answers.. and what is the difference between them.. .pls help me.. manish Just to be pedantic the compiler actually doesn't generate code that copies the object one bit at a time - it is at least one byte at a time. But the underlying meaning is the same: the way I think of it is a shallow/bitwise copy can be done using memcpy while a deep/member wise copy requires calling copy constructor/assignment operators for user-defined types. Note: for built in types, like int, char, etc., there is only one way to copy ...Show All

• Internet Explorer Development IE 7 / Vista - Legacy Mode

  Does anyone know if the final release of Windows Vista will include the ability to run IE in a "Legacy Mode", i.e. running IE 6 in Vista We have many ERP applications that are unsupported on IE7 and we are looking to determine the impacts of upgrading. Any information on this would be greatly appreciated. The closest to a legacy mode in IE7 is the CSS compatibility mode (aka "quirks mode"). IE lets developers choose between one of two rendering modes for CSS. If a web page contains a strict !DOCTYPE directive, IE will display it in strict mode (emphasizing standards compliance over compatibility). IE7 can also display CSS as it did in older versions of the browser; this so-called &q ...Show All

• Visual Studio 2008 (Pre-release) Getting list of all dependency/attached properties of an Object

  In Visual Studio, in the XAML view when we add a element tag say <Rectangle...> and hit the spacebar, we get a list of all the attached properties and dependency properties of the object. (For e.g. Canvas.Left). How can this be achieved through procedural code I tried using Reflection (on a Rectangle object in above case) but it did not help. Thanks, Niranjan you can try something like this Type t = typeof ( Button ); while (t != null ) { FieldInfo [] fs = t.GetFields(); System.Diagnostics. Debug .WriteLine(t.ToString()); for ( int i = 0; i < fs.Length; i++) System.Diagnostics. Debug .WriteLine( "\t" + fs .Name ); t = ...Show All
