Re: Creating COM objects with Ada

[David Botton <David@Botton.com>]

I would call it "luck".

The objects are working for some people under Win95, but still no luck on
Win98.

There are some other problems with the GNAT version when it is being used
by code written in GNAT, and is being looked at.

I suspect some of the problems Robert Dewar has could have come from not
including documentation for making DLLS with GNAT in 3.11p and better
documentation for 3.12 (what I've seen needs more work).

I think you'll find all is in order with the DLLs -

Perhaps you should work something out for those that can not afford the
tens of thousands for support contracts, but are pushing GNAT in to the
next century.

Never the less, I am very gracious for what ever bones you have thrown to
the public, with out them I wouldn't have started using Ada.
