Latest VAX, Win7, VC2008

Consider following example:

namespace a
{
	class CInterface
	{
	public:
		enum enFoo{};
		virtual void Foo( const enFoo ) = 0 ;
	} ;
}

namespace b
{
	class CImpl: public a::CInte[Implement Method]rface
	{
	public:
		virtual void Foo( const enFoo ) // Qualifier missing for enum
		{
			throw std::exception("The method or operation is not implemented.");
		}
	} ;
}

The enum type resolution is missing a namespace qualifier.

I am seeing the same effect here, but this code is compiling just fine for me in VS2008, which was a surprise to me. Does this compile for you?

Ok, this example was not so smart... The enum is inherited so it is known.

Add an other enum just to the namespace "a" and add a parameter with this enum to the "CInterface::Foo" method. Than "Implement Interface" again in the "CImpl" class. Now the namespace qualifier is missing.

Btw: Did not tried typedefs or other classes in different namespaces as parameters, but I think this would make some trouble too. Also did not tried return-types.

Thank you for the additional information. I was able to reproduce the problem via moving the enum out of the class, directly into the namespace:
