Hello,

I'm trying to develop a simple Midas function that returns an array of 
strings 
to the client.
Using the TLB interface in the C++Builder 5, I've created a simple function 
prototyped like this:
STDMETHODIMP MidasImpl::foo(TVariant *array /*out*/, int *array_size /
*out*/);

My questions are:
- On the server side, how do I build a TVariant that countains an array of 
N 
strings (the value of N will be returned to the caller via the array_size 
parameter)?
- Then, how do I recover the string array on the client side?
I would prefer an help in C++ rather than in Delphi.

Thanks for your help.

Eric
