Cédric,

Thank you for your answer.
But I think it's more difficult.

classA is the base class for all my messages (objects exchange through mailslots).
classB, classC, etc have herited from classA (they are more sophisticated messages).

My function called "Duplicate" function is in reality a function to send a message of classB, C, etc to SEVERAL mailslots (several destination).
So, I want to "give" my sophisticated message reference with its type (which is typeid( xVar)) to my function, wich will do a loop in order to duplicate the given message as necessary as to send it to ALL the mailslots.
It's the destination thread which delete the object after processing.
So, I want to "clone" the object, but the parameter of the function is of type "classA" (which is common to all types), and the type is only known by TYPEID.

Is there a possibility to do that ?

Best regards

Ok,
Now I have understand the mechanism.
Only a small detail : all the Clone() methods needs to have the same return type. So it's necessary to cast the returned result :

class classB : public classA
{
//...
}

classA* classA::Clone()
{
return new classA(this);
}

classA* classB::Clone()
{
return (classA *) new classB(this);
}

Thank you.

Hi, sorry for the late answer but I was in holidays.

Not necessarily, you can use a 'covariant return type', which means that your classB::Clone method can return a classB* (because classB inherits from classA). Anyway, you never need to cast classB into classA: classB IS already a classA object.

We use Inno Setup[^]. It is a very good freeware installer.

Yes, it is possible. You just have to create an iss file and specify in it which files are part of the setup.

How many number of connections have you made?.This limitation could be because of the limitation of the Access Driver. Close some connections and try again..

Then you'll need to treat the numbers as strings instead.
