• Debugging embedded Lua

  - by Caspin

  How do you debug lua code embedded in a c++ application? From what I gather, either I need to buy a special IDE and link in their special lua runtime (ugh). Or I need to build a debug console in to the game engine, using the lua debug API calls. I am leaning toward writing my own debug console, but it seems like a lot of work. Time that I could better spend polishing the other portions of the game.

• What's the point of Mono on Windows

  - by Adam Haile

  This may be a dumb question...but I was just looking into the Mono project and they have a section about installing Mono on Windows. But, since Windows obviously already has the .NET runtime can anyone tell me what exactly is the point of having Mono for Windows? Does it help with cross platform development or something?

• WPF Property Data binding to negate the property

  - by azamsharp

  Is there any way to change the value of property at runtime in WPF data binding. Let's say my TextBox is bind to a IsAdmin property. Is there anyway I can change that property value in XAML to be !IsAdmin. I just want to negate the property so Valueconverter might be an overkill! NOTE: Without using ValueConverter

• fake python modules via symlinks: on windows?

  - by eudoxos

  I have several compiled python modules; they are put into a single .so (to avoid runtime linking, there are cross-module symbol dependencies), but a number of symlinks points to this .so: libfoo.so -> liball.so libbar.so -> liball.so liball.so This way, I can do import foo (Python will call initfoo() defined in liball.so) or import bar (calls initbar()). I am wondering if this approach will work on Windows?

• MinGW/GCC Delay Loaded DLL equivalent?

  - by VoiDeD

  Hello, I'm trying to port some old MSVC C++ code to MinGW/GCC. One problem is that the project relies heavily on the /DELAYLOAD option for functions that aren't always used, and where the proper dll is located at runtime. Is there such a similar option on MinGW/GCC? This code is targeting the windows platform.

• gtk2 auto translation is choosing the wrong language

  - by Andrew Heath

  Not sure if yall can help this time, as I'm just using this particular program not coding with it... I downloaded Deluge, a free torrent app, and it requires GTK2 Runtime which I've also installed. Unfortunately, on my English WinXP with East Asian Language support Deluge sets itself to Chinese menus and has no option to alter the language. A bit of poking around on the internet suggests this is due to GTK2 selecting the wrong default language. Does anyone know how I can override this?

  I would like to display static (shared) objects at runtime in a PropertyGrid but if I try to set the selected object property of the grid like this: _propertyGrid.SelectedObject = System.Windows.Forms.Application I get a compilation error: 'Application' is a type and cannot be used as an expression. Is there a way to display a static (shared) object or the object's properties in the PropertyGrid?

• Adding new functionality to an application using on-the-fly class generation

  - by James P.

  Is it possible to generate subclasses at runtime or while an application is running? If so, how is this achieved and what precautions should be taken to prevent a rogue object wreaking havoc inside an application? Edit: Title modified from "Class generation on the fly".

• What happens in memory when a C++ class is instantiated

  - by Jo Bucher

  I'm interested in the nuts and boltw of C++ and I wondered what actually changes when an object is instantiated. I'm particularly interested if the functions are then added to memory, if they are there from runtime or if they are never stored in memory at all. If anyone could direct me to a good site on some of the core bolts of C and C++, I'd love that too. Thanks, Jo

• Is SparkViewEngine dying?

  - by Stephane

  Hey, I am building a email service based on templates. I thought of using the spark view engine but it seems that It doesn't get much updates anymore. Support on .NET4.0 is not even yet complete and it fails at runtime when used in a console app. The little Intellisense support that was there in VS2008 doesn't seem to work on VS2010 (from the information I have found) Should I avoid it? What do you think?

• Is it possible in AvalonDock to programatically change DockableContent state to floating?

  - by Marqus

  In my application I'm loading windows from 'plugins', so my app doesn't know them until runtime. I'm creating DockableContent for each plugin and sets it's Content to Control returned by plugin. Each plugin tells, if it's window should be initially docked or floating, user can change it later. So I have an instance of DockableContent and I want to change it to FloatingWindow programatically. Changing content.DockableStyle to DockableStyle.Floating isn't enough, what else I have to do?

• Faster integer division when denominator is known?

  - by aaa

  hi I am working on GPU device which has very high division integer latency, several hundred cycles. I am looking to optimize divisions. All divisions by denominator which is in a set { 1,3,6,10 }, however numerator is a runtime positive value, roughly 32000 or less. due to memory constraints, lookup table is not option. Can you think of alternatives? I have thought of computing float point inverses, and using those to multiply numerator. Thanks

• Why do we need to use out keyword while calling a method

  - by Midhat

  When a method is defined with an out parameter, why do I have to specify the out keyword when calling it. Its already there in the method definition, and the runtime should know that any parameter passed will be an out parameter. It would make sense if the compiler will accept the argument with or without out keyword, with different semantic, but if you MUST add the keyword to make the code compile, whats the use? Shouldn't the compiler handle it automatically? Same for ref

• How to get a compiler warning when an IBOutlet is disconnected

  - by Vincent Gable

  How can I have Xcode warn me if an IBOutlet of one of my objects is not hooked up to anything in a NIB? I can check that outlets are connected at runtime by adding assert(ofEveryOutlet); in awakeFromNib or viewDidLoad. But it's not as useful, or reliable, as having the compiler do the checking for me.

• Dynamic inheritance/implementation in PHP 5.*

  - by Rolf

  Hi everyone, I'm implementing a Logger, based on a XML declaration (path to class, method name, custom log message). There is also a Logger interface that defines the function __call, the latter logs what's needed and then relays the call to the target method. The only difficulty is to make each class, declared in the XML file, implement this interface with __call. So finally my question: is there a way to set at runtime the parent class or the implemented interface of another class ? Thanks in advance ! Rolf

• Adding resources to solution explorer in experimental hive

  - by Brian Webb

  Hi, I'm currently working on a project using DSL tools in Visual Studio 2008. Is there a way to automatically add a resource into the solution explorer of the experimental hive at runtime? I'm creating new diagrams based on what is on screen, and saving them into the directory the project is stored in. I would like to know if there is a way to get them to automatically get added to the solution explorer? (I don't want to have to drag the files in manually each time)
