Inside COM, Rogerson, Microsoft Press ISBN 1-57231-349-8, top of page 112: Pronounced goo-id to rhyme with druid. Not sure what the geoduck stuff is about though?!

We just hit this one, it is because of a #define in stdio.h which defines EOF as -1. The easiest quick and dirty fix is to do a #undef EOF before the line in the file if the C library EOF define is not used further on.

Here's hoping! And maybe context sensitive help while they are at it.

I have a Fenix L2D Cree Q5 Premium, best torch I have ever bought. Bit on the expensive side, but really recommended. http://www.fenixtorch.co.uk/led_torches/fenix_l2d_q5.html[^]

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 there is a wider question here - are we saying that the .net languages do not support const correctness at all, or is the syntax just different? Unless you didn't guess I am from a C++ background! For instance if I have a const handle to an object, how do I restrict the caller to only calling certain functions - for instance getters which do not modify the object and not setters which would cause the object to be modified?
