DLL in C++Builder6

[Henrique O. Santos]

Hi all.

I'm trying to export a class and its instance in a dll in c++builder.
My class definition in the dll project is like this:

class __declspec(dllexport) TableTest
{
// class definitions with only public functions and data fields.
};

__declspec(dllexport) TableTest Test;

-----------

In my other project in wich i use the created .dll and .lib, i have:

class __declspec(dllimport) TableTest;
__declspec(dllimport) TableTest Test;

But when i try to access any of functions or data fields from Test
(like: Test.Name) i get the following compile error:

E2315: 'Name' is not a member of 'TableTest', because the type is not
defined yet.

Thanks for any help.

Henrique.

Let's put aside all the off-topic nonsense like __declspec and such.
One rule remains in effect: in order to call a member function, the
compiler has to know that it exists, what its arguments are and what
its return value type is. You give this information to the compiler
in the form of the class definition. Your "other project" apparently
doesn't have the benefit of the class definition. How do you suppose
the compiler should be able to deal with that?
