Public Not Creatable objects

I am creating an Active X component to use with a standard exe program that must use Public Not Creatable as the instancing type. I have been told to create an object using 'Specials' as the type in the std exe, and a provide a method in the Active X component that returns the address of single (global) 'Specials' object in the Active X server. The std exe should then be able to access the single object and its methods. What does 'Specials' type mean?  How do I return the address of the global object? How do I go about this? I am a novice VB5 user.

I don't know where you read this 'Specials' word. the meaning of PublicNotCreatable is that you can't create the instance of that class by using New or CreateObject. You have to provide one more object which is pulically creatable and which interns create this object and passes the reference to the program.
  for example you can't create the rdoconnection obejct by just saying new or create object you have to use the openconnection method of rdoenvironments to create rdoConnection.

Thanks for the reply - I'll just check that I understand correctly: so now I will code a send object which will create my Public Not Creatable object. Then I create this second object from my other program (the standard exe) and ask the second object for the address of the object it created.

Now - if thats right - ho exactly to I get the address of the first object from the second object?

just a note on this older question... I think what tlaver was told to create; "an object using 'Specials' as the type" meant that he was to create a user-defined public data type called 'Specials' in the COM component that could be used in the standard exe.
