Hi all, I've done a pretty basic class in C++/CLI using generics. How can I check if the generic array^ equals nullptr? generic<class T> where T: IGenericContainable public ref class FIBEXGenericContainer abstract : AbstractFIBEXNode { public: property array<T>^ Children; public: property T default[String^] { T ...
I am writing two C++/CLI assemblies. One assembly has a base class with some internal virtual methods. The other assembly is marked as friend and contains derived class. When I try to override the internal virtual method, the compiler is forcing me to change the visibility level to public. What is going on? Why do I have to do this? C...
Hi guys, I am having the strangest problem...When I convert from a textbox->text into a double , I get the number .99999999991 if a zero was in the text box. Why is this? Here is my example code: double theNumber = 0; if( !double::TryParse( mTheText->Text, theNumber ) ) { return false; } Notice that double is set to zero at the s...
I have a generic items list class to create a more specific listing using it as base class, something like this.. ref class ItemBase { } ref class ItemA : ItemBase { } ref class ItemList abstract { public: virtual void add(ItemBase ^p); } ref class ItemListA : ItemList { public: virtual void add(ItemA ^p) override; // it doesn't w...
How can we translate this C# code: Mesh m7 = new Mesh(); m7.MakeFace(new ICurve[] {(ICurve) redLp }, new ICurve[][] { new ICurve[] { circle } }, Plane.XY, tol, true); To Managed C++? Thanks! ...
I'm new to C++/CLI, so please bear with me... I'm working on a mixed C++/CLI DLL, which should act as a bridge between a Win32 process and a .NET assembly. In the DLL, I need some .NET stuff to be present during the lifespan of the DLL. Initializing is not that big a problem, but I couldn't figure out when can I safely cleanup the .NET ...
Hello, From a managed c++ function I want to invoke an unmanaged function that expects a 'const char *' as an argument. Are a) and b) below correct? For b), do I need to pin_ptr 'hello'? What about a)? Thanks. a) myFunction( "hello" ); b) char hello[10] ; strcpy( hello, "hello" ); myFunction( hello ); ...

Hello, I need to generate structs and classes at run time in C#(might be in CLI) managed environment. Suppose I have all data and all data types associated with those data memebers of some class/struct.

I come from a .NET background and will be going into the field of rendering / graphics using OpenGL/DirectX. For this purpose C++ will be my language of choice to interact with these rendering frameworks. As I understand it Visual C++ allows native support for CLI which is an extension to C++ that allows the application to benefit from ...

Hello! I am doing a bit of research before I am going to write my own 2D (and maybe some 3D) game engine. I have made an engine before using C# and XNA but I want to go cross platform this time by making my new engine in C++ using opengl etc. But ... I still want the fast iteration times from C# and have access to the game engine there...

WPF applications are, at its core, managed applications? Right? So, I have to choose between using managed C++ or managed C#. I experimented with managed C++ years ago. It seemed to be not quite be ready for primetime. I'm guessing Microsoft has put more effort into managed C# than managed C++. So, it seems like using managed C# is...
Hi, I am getting a memory leak whenver a new RPC thread in a DCOM server (c++ DCOM server) invokes the following managed C++ method void CToolDataClient::SetLotManagerActive(bool bLotManagerActive) { if( m_toolDataManager != nullptr) { m_toolDataManager->LotActive = bLotManagerActive; } } I get the managed C++ object point...
I have a function, singleFrameEventHandler, that I wish to be called when a certain event, OnNewFrame, occurs. After doing some research, it seemed to me that functions which handle events have a void return type and take a parameter of the type that contains the event. From what I could find online, that is done like this: Function dec...
