Assuming your native code is enum shape_type_e { stUNHANDLED = 0, //!< Unhandled shape data. stPOINT = 1 //!< Point data. … }; and your managed code is public enum class ShapeType { Unhandled = 0, Point = 1, … }; You can cast from the native to the managed using shape_type_e nativeST = stPOINT; … Read more
Turned out that I needed to delete all of the project temp files inc. caches etc., kill the debug symbol server and restart windows.
I added a Get only property and backed it up with a const in the definition. public interface IFoo { string ConstValue { get; } } public class Foo : IFoo { public string ConstValue => _constValue; private string _constValue = “My constant”; }
It is not supported because the std::mutex implementation uses GetCurrentThreadId(). That’s a winapi function that is not supposed to be use in managed code since it might be running on a custom CLR host that doesn’t use threads to implement threading. This is the good kind of problem to have, it shows that you are … Read more
Here’s what I could dig up myself, for x86-64 doing FP math with SSE2 (not legacy x87 where changing the rounding mode for C++’s truncation semantics was expensive): When I take a look at the generated assembly from clang and gcc, it looks like the cast int to double, it boils down to one instruction: … Read more
Managed C++ is the version in VS2002 and VS2003. It had race conditions and other serious bugs, as well as being confusing. It’s no longer supported. In VS2005, Microsoft introduced C++/CLI, which has also been accepted as an ISO standard. It’s also supported in VS2008 and the upcoming VS2010. Both of them had the same … Read more
whether .Net Core(CoreCLR) supports C++\CLI (clr\oldsyntax) runtime environment ? As far as I know there is no plan to support C++/CLI with .NET Core. If no, what can be the possible solutions to this application work ? You can (should) provide a C API. Mono e. g. supports P/Invoke and .NET Core also supports P/Invoke … Read more
When I want to debug native code as well as C++/CLI, I do following: In C# application, check Allow unsafe code in Build tab and Enable unmanaged code debugging in Debug tab of project properties. For C++/CLI dll project, In Debugging tab of properties, set Debugger Type to Mixed
In C++/CLI, use the typeid keyword. e.g. Type ^t = Int32::typeid; In the older “Managed C++ Extensions” syntax, you’d use __typeof(Int32), but that whole version of the language is severely deprecated and you should be using C++/CLI.
You do, indirectly, marshal.h includes it. It dumps an enormous amount of identifiers in the global namespace. The macros are especially awkward, lots of them match names used in the framework. Lots of things that marshal.h does can be done by the Marshal class as well. But I can’t help you with that, you didn’t … Read more
