c++-cli

In C++/CLI , you can use native types in a managed class by it is not allowed to hold a member of a native class in a managed class : you need to use pointers in that case. Here is an example : class NativeClass { .... }; public ref class ManagedClass { private: NativeClass mNativeClass; // Not allowed ! NativeClass * mNativeClass; // OK auto_ptr<NativeClass> mNativeClass; //Not allowed ! boost::shared_ptr<NativeClass> mNativeClass; //Not allowed ! }; Does anyone know of an equivalent of shared_ptr in the C++/CLI world? Edit: Thanks for your suggestion, "1800-Information". Following your

I'm porting a solution from MSVS2005 to MSVS2012. The projects are in C++ .NET but use homemade native C++ libraires too. We had no problem building the projects with 2005 but now, I'm unable to build a project using 2012. I get the following error message: MyFile.obj : error LNK2022: metadata operation failed (801311E4) : Duplicate managed types have different visibilities. What does this mean? What info do you need to help me? Thanks for your help? I found the bug. It is a mix of everything that has been suggested here. Somewhere in the project, a native C++ header file is included. A class

Is there a simple way to check the type of an object? I need something along the following lines: MyObject^ mo = gcnew MyObject(); Object^ o = mo; if( o->GetType() == MyObject ) { // Do somethine with the object } else { // Try something else } At the moment I'm using nested try-catch blocks looking for System::InvalidCastException s which feels ugly but works. I was going to try and profile something like the code above to see if it's any faster/slower/readable but can't work out the syntax to even try. In case anyone's wondering, this comes from having a single queue entering a thread which

I can't get the contents of an C++/CLI enum to show up in a C# project. I can see inside a class I wrote, and even see the enum, but I can't see the enum values. So I can't use the thing on my C# side. Any reason why contents of a C++/CLI enum wouldn't show up. My C++/CLI project is compiled as mixed to reuse a C++ library. And I'm using Visual Studio 2005. Make sure you used enum class to create a .NET-compatible enumeration, and not a native C++ enum type. Later versions of Visual C++ require public enum class , to disambiguate from the enum class contextual keyword which is part of C++11

I have a client application in native c++ code which is using native c++ dlls. I am investigating the possibility of connecting this code with c# dlls as they would be much easier to write. I decided to write a c++/cli bridge dll which can be loaded with LoadLibrary and which would pass the calls to c# dll. The communication between the client and the dll is such that the client passes a pointer to an interface object through which the dll then communicates with the client. I wrapped this object in the c++/cli bridge code for the c# code to use it. The bridge should also expose several
