cliext::list strange behavior
-
I am trying to use a cliext::list<> and am hitting various problems - apologies, its a long one - but stick with me :) . Before I start, I am using Visual Studio 2008 with service pack 1. I am (relatively) new to mixed mode programming - my background is pure C++ / MFC, etc - so it is entirely possible I am misunderstanding something. I have reduced my first problem to the following: Header file: #pragma once #include private ref class TestClass { cliext::list ^ m_list; public: TestClass(void); }; .cpp file: #include "StdAfx.h" #include "TestClass.h" TestClass::TestClass(void) : m_list(gcnew cliext::list()) { } Produces this little lot...

I think you need to make
ref struct SInsideaccess level "public" due to the usage of generics in STL/CLR. However, if thisref struct SInsideis only going to be accessed within the same assembly, you can make it's access level "internal" or "protected public"."We make a living by what we get, we make a life by what we give." --Winston Churchill
