Sending back a collection object

I am a newbie in COM, and I am looking for the way to create a method that
returned for the result an object collection of strings. Can someone have a
sample for doing that ?
Thanks.

>array of strings<.

For example I need some thing like that:
STDMETHODIMP TCustomToolsImpl::GetArrayOfStringsOut(BSTR* Value
/*ou,retval]*/)
{
char *array[3]={{"sunday"},{"monday"},{"tuesday"}};
*Value=(Variant)array;

}

And use this array in JScript after.
How writing correctly the mlethod ?

Re:Sending back a collection object

I'm not sure about as a result, but that is possible using the SAFEARRAY
construct. Look at variants, OleVariants, and the like. You can pass these
as out parameters.
