error C2955: 'Vector' : use of class generic requires generic argument list

Herby

Iv defined the following class in vector.h

using namespace System::Collections::Generic;

generic<typename T1>
ref class Vector : public List<T1>
{
public:
Vector(void);
};


I would really like to put the implementation in the cpp - is this
still not possible - also with generics?


// vector.cpp

Vector::Vector(void)
{
}

But i get the above error!
Have i just defined it wrong? or must it all go in the header?

With generic it is possible, but similar to templates you have to write

generic<typename T1>
Vector<T1>::Vector(void)
{
}

Cheers Marcus,

I did just solve that.

I hope your keeping well. I was on your course in London.

with templates this is not practically possible since VC does not support
the export keyword. with generics it seems to work without a problem.
// vector.cpp

Vector::Vector(void)
{
}

you used the wrong syntax.
this should work in your cpp file:

generic<typename T1>
Vector<T1>::Vector(void)
{
}

Thanks guys.
What about operator overloading, is this supported by generics?
Is it part of the CLR?

Yes.

Actually I didn't know for sure because I only used overloading on
non-generics.
To test it I've just overloaded the == operator on your generic vector and
it seems to work just fine.
