问题 I have a C# function that I made into a DLL: public static string Test(string name) { return "Hello " + name; } In C++/CLI project I successfully import that DLL, now I want to have a way to call that function and make it available for normal unmanaged C++. So I want to export the C++/CLI function like this: extern "C" __declspec(dllexport) void __stdcall Example(char* name, char* greet) { // name will be passed to C# Test(...) function // and greet will contains the returned value // call to

问题 I have a scenario where a C# library is consuming a mixed mode C++ library. The use case is as follows: 1) The C# code initializes a listener from the library (managed c++), which initializes a listener from native C++. 2) The native code receives a message and parses it, then passes it to the managed c++ via IJW code 3) The managed c++ calls a delegate from the C# code with the message This all works fine, except for the very last part - actually including the message. The C# code can't

问题 Is it possible to manipulate .net controls from native code? Particularly, I'd like to set the text of a TextBox from some native code. I want it done this way to keep the business logic separated from the user interface, but it is precisely the native code which only knows how to appropriately format the data (some bytes received within a protocol). I know I could get the window handle through the Handle property, but once there, how would I call the desired method? Is string handling my

问题 I would like to change the Name property of an XmlElement in c++/cli. I would like to do myXmlElem.Name = "xyz" , but the compiler tells me that I can't do a set operation on the Name property. i.e. <abc/> changed to <xyz/> How can I achieve this? Thanks! 回答1: you can't change the Name property of an XmlElement like that (Name is read only). you can however do something like the following (example in C#). XmlElement xyz = myXmlElem.OwnerDocument.CreateElement("xyz"); myXmlElem.ParentNode

问题 I am using Visual C++ 2010 Express. I have a form ( Form1.h ) that contains a button ( btn1 ) and a label ( label1 ). When I click the button, I would like to call a function from a different header file ( testing.h ) that will then proceed to change the text in the label. What I have is something like this... Form1.h #include "testing.h" ... standard form code generated by Visual Studio private: System::Windows::Forms::Label^ label1; ... private: System::Void btn1_Click(System::Object^

问题 I am using visual studio 2008 and I have a native c++ project that loads a managed c++ dll, but on the last one, the intellisense doesn't work anymore only for the managed code. This project (dll) has a mixed code (native and managed) and if I write only "::" on a clean line, the intellisense gives me the methods inherits from the base class, like regular, not for the managed code, for example array <String^>^ ContactListToChat; I need help, otherwise I´ll have to fly blind. 回答1: Taken from

问题 I am developing a managed lib (using Microsoft Web Services) and I am including it into a c++ project. The project doesn't use /clr option, so when I include my library's header file VS2005 show me an error saying I have to use /clr option.

Any suggestion is welcome. Thank you in advance. 回答1: If you have unmanaged

问题 How do I make use of the .NET framework namespaces from C++? 回答1: C# will be using System; using System.Configuration; C++ will be using namespace System; using namespace System::Configuration; Don't forget to reference the libraries in your C++ project properties. 回答2: You can do this in managed C++. Use #using directive and use the namespaces like you normally do. 回答3: Start Here: Pure C++: Hello, C++/CLI 来源： https://stackoverflow.com/questions/736786/how-to-use-namespaces-of-net-in-c
