c++-cli

I am trying to set up a C++/CLI project using cmake. I have had success doing this with visual studio 2010, but I am now working with a legacy solution that requires visual studio 2008. In visual studio 2010, it is enough to set up my cmake like this: set_target_properties(${PROJECT_NAME} PROPERTIES VS_DOTNET_REFERENCES "${CMAKE_CURRENT_SOURCE_DIR}/../OrionMaster/3rdParty/GMap.NET.Core.dll;System;System.Core;System.Data;System.Drawing;System.Xml;WindowsBase") set_target_properties(${PROJECT_NAME} PROPERTIES COMPILE_FLAGS "/clr /EHa") set_target_properties(${PROJECT_NAME} PROPERTIES DEBUG

i have written a Win32/net DLL, it works fine under Win XP, Win7 and 8 but under Win 8.1 it fails. Dependency Walker says: API-MS-WIN-CORE-KERNEL32-PRIVATE-L1-1-1.DLL not found (user32.dll will call them) Google means, MS changed some System-DLLs in 8.1 (and ignored compatibility), so that many programs have the same problem. Full list with "file not found": API-MS-WIN-CORE-KERNEL32-PRIVATE-L1-1-1.DLL API-MS-WIN-CORE-PRIVATEPROFILE-L1-1-1.DLL MSVCR120.DLL API-MS-WIN-CORE-SHUTDOWN-L1-1-1.DLL API-MS-WIN-SERVICE-PRIVATE-L1-1-1.DLL EXT-MS-WIN-NTUSER-UICONTEXT-EXT-L1-1-0.DLL IESHIMS.DLL Does

In C#, I like the var keyword for situations like this: var myList = new List<MyType>(); Is there any equivalent in C++/CLI, or do I have to repeat the type name everytime just like this: List<MyType ^>^ myList = gcnew List<MyType ^>(); Could not find an explicit statement in the docs or by Google so far. I am using Visual Studio 2008. In Visual Studio 2008 there is no such equivalent. However with Visual Studio 2010 you can use the auto keyword to implement var like semantics in C++. I know this works with non-managed C++ and I'm fairly certain it works for C++/CLI as well. I know that type

How can I send a managed object to native function to use it? void managed_function() { Object^ obj = gcnew Object(); void* ptr = obj ??? // How to convert Managed object to void*? unmanaged_function(ptr); } // The parameter type should be void* and I can not change the type. // This function is native but it uses managed object. Because type of ptr could not be // Object^ I called it "Unmanaged Function". void unmanaged_function(void* ptr) { Object^ obj = ptr ??? // How to convert void* to Managed object? obj->SomeManagedMethods(); } The cleaner and the better approach is to use gcroot

I use in my C++/CLI project ToBase64String to give a string like /MnwRx7kRZEQBxLZEkXndA== I want to convert this string to Hexadecimal representation, How I can do that in C++/CLI or C#? bryanmac FromBase64String will take the string to byte s byte[] bytes = Convert.FromBase64String(string s); Then, BitConverter.ToString() will convert a byte array to a hex string ( byte[] to hex string ) string hex = BitConverter.ToString(bytes); Ranhiru Jude Cooray Convert the string to a byte array and then do a byte to hex conversion string stringToConvert = "/MnwRx7kRZEQBxLZEkXndA=="; byte[] convertedByte

[All of the following was tested using Visual Studio 2008 SP1] In C++, const qualification of parameter types does not affect the type of a function (8.3.5/3: "Any cv-qualifier modifying a parameter type is deleted") So, for example, in the following class hierarchy, Derived::Foo overrides Base::Foo : struct Base { virtual void Foo(const int i) { } }; struct Derived : Base { virtual void Foo(int i) { } }; Consider a similar hierarchy in C++/CLI: ref class Base abstract { public: virtual void Foo(const int) = 0; }; ref class Derived : public Base { public: virtual void Foo(int i) override { } }

#using <mscorlib.dll> #using <System.dll> using namespace System; using namespace System::Text; using namespace System::IO; using namespace System::Net; using namespace System::Net::Sockets; using namespace System::Collections; Errors: IntelliSense: "#using" requires C++/CLI to be enabled.... how to fix this prob!? Your project settings are wrong. Specifically Configuration Properties, General, Common Language Runtime support. Fall in the pit of success by starting your project by picking one of the project templates in the CLR node. Choose Project -> Properties from the menu bar. In the
