c++-cli

问题 In a C# app, I'm referencing a native C static lib, that I wrapped in a C++/CLI DLL. I chose a static lib versus a DLL because I have other constraints related to the release process of the app to the user. Among the many topics available on this forum I found the following implementation. Main : { MyCLRDLL test = new MyCLRDLL(); if(test.go()) Console.WriteLine("Hello, wrld"); } In the DLL project, the file MyCLRDLL.hpp #include "MyNativeLib.h" #pragma comment(lib, "MyNativeLib.lib")

问题 I am currently working on a visual editor to build Finite State Machines. The core is c++ since the built FSM will run in a game. The editor is c#. I was able to get a CLI wrapper going so I can build everything I need in the c# side. The last thing I am trying to do, is to be able to expose a templated class to c#. I started by creating a managed class: template <typename T> public ref class TestTemp { private: ClassToWrap<T>* m_val; public: TestTemp(T val) : { m_val = new ClassToWrap<T>();

问题 I have developed a wrapper for a library that uses a callback to notify events. This callback is called using another thread than UI's thread, so the wrapper uses the following script to call the event handlers into the right thread for a WinForm application. void AoComm::Utiles::Managed::DispatchEvent( Delegate^ ev, Object^ sender, Object^ args ) { ComponentModel::ISynchronizeInvoke^ si; array<Delegate^>^ handlers; if(ev != nullptr) { handlers= ev->GetInvocationList(); for(int i = 0; i <

问题 I have a Text Box that is a System::String^ , I need to confirm that this only accepts 10 digits numbers and no letters, symbols, etc. How would I implement this in C++ visual studio? Do I need to convert the contents to a std::string first? 回答1: Assuming this is a .NET winforms text box (since your snippet is C++/CLI), you want to set the "MaxLength" property. (Something like TextBox^ tb = gcnew TextBox(); tb->MaxLength = 10 .) For the numbers-only part, you want to assign a delegate to the

问题 I'm trying to make a great GUI for my csgo cheat. I decided to use C++/CLR. Firstly I create empty project then, I change in a properties entrypoint and the subsystem and I add this code to the cpp file: #include "MyForm.h" using namespace System;` using namespace System::Windows::Forms;` [STAThreadAttribute] void Main(array<System::String ^> ^args) { Application::EnableVisualStyles(); Application::SetCompatibleTextRenderingDefault(false); SmallPackofCheats::MyForm mainForm; Application::Run(

问题 I'm interfacing the statistical language R direcly from .NET using managed c++. I'm a little green in Managed C++, and I need to do something a little tricky. A structure use to pass to a function has a generic data pointer void* used to pass some payload data usable in a later callback. Hope I explained, is a pretty well used pattern in C/C++. But for my use I need to pass a managed object by using that void * , how can I do? I'm trying with: BinaryWriter^ bs=gcnew......; stream->data=(void*

问题 Consider the following C# code. string[] stringArray = new string[10]; foreach (string s in stringArray) s = "a new string"; // Compiler error - Can't assign to foreach iteration variable Now consider the following valid C++/CLI code. array<String^>^ stringArray = gcnew array<String^>(10); for each(String^% s in stringArray) s = "a new string"; When foreach is used with array type, compiler translates it into normal for loop. This implementation is same for C# and C++/CLI. So I wonder if C++

问题 This question already has an answer here : How do I create a C++/CLI Winforms app in VS2012? (1 answer) Closed 3 years ago . This issue has been around for all Visual Studio versions, but in VS 2015 the "old tricks" don't seem to work anymore. This is what I have tried: create a Windows Forms application in VS 2013 and 2015 (the macro is missing since VS 2013, so see this post: Can't find Windows Forms Application for C++) add boost headers path to Additional Include Directories add #include

问题 I have a C++ unmanaged class NativeDog that needs to be used from C#, so I've create a wrapper class ManagedDog . // unmanaged C++ class class NativeDog { NativeDog(...); // constructor ~NativeDog(); // destructor ... } // C++/CLI wrapper class ref class ManagedDog { NativeDog* innerObject; // unmanaged, but private, won't be seen from C# ManagedDog(...) { innerObject = new NativeDog(...); ... } ~ManagedDog() // destructor (like Dispose() in C#) { // free unmanaged resources if (innerObject)
