1 To mean what C++ would call a pointer - e.g if you have SomeClass myObj; then myObj is a reference variable in .Net-speak, or a pointer to an object of type SomeClass in C++ speak. 2 In parameter passing where a parameter passed as ref can be changed by the method so as to affect its value outside the method.
Question 0 Sign in to vote I have some problem reparing or uninstralling Microsoft Visual C++ 2012 Redistributable (x64) - 11.0.60610 He tell me: Setup failed
One option is to use LocalAlloc in your C++ code instead of new; this could be freed in C# using System::Runtime::InteropServices::FreeHGlobal. Another is to use CoTaskMemAlloc instead of new from C++, and System::Runtime::InteropServices::FreeCoTaskMem from C# to free it. Any method of allocating memory from C++ other than these two will require what you suggested -- writing another function ...
I work with VS 2015 on large C++ project where are used C++ 11 features like: variadic templates, function objects created with lambdas, variants, function objects base on std::function and other all possible modern C++ 11 features. I have problems to compile several pieces of code which is buildable and runable with CLang and G++ .
MFC is not part of the C++ language, so a better place for MFC question is the VC General forum, which covers VC libraries. The C++ language forum does not cover everything you can do in the C++ language--otherwise it would overlap with all other .Net and Windows SDK forums.
I'm developing a C++ Regular dll Dynamically linked to MFC (Microsoft Foundation Class libraries) that consumes WRT extension. The dll is intended to provide methods that interact with the BLE devices in range.
I never have written such a program in c++ , so need some help with it, but i did managed to write a DLL program in C# which includes the function Get_Status, and returns the String Of Arrays, so i can i use in in C++ Windows Form Project.
I have an unmanaged C++ DLL with a number of static functions that I need to call from C#. What do I need to do in a C++/CLI wrapper to be able to call the static functions from C#? If all the methods are static, then just create a managed class with static methods that call the ones in the unmanaged class.
These concepts are fundamental to OOP programming in nay language, and I would advise you to study them in a simpler setting than WinForms in C++/CLI, for example a console program in standard C++.
In the C++ world, this will be called by passing a SAFEARRAY of BSTR's. So you need to convert your std::vector<const char*> to a SAFEARRAY of BSTR's first and pass that as the input parameter to your C# routine.
