Ada and Windows COM

Ada and Windows COM

[Tim Rowe]

Is there any (free!) way of using MS Windows COM from Ada? I've looked 
at GNATCOM, but that won't build with the current version of gnat. The 
community says that they're working on it, but there's no news on when 
it will be fixed so I could do with an alternative.

TIA,

Tim Rowe

In the meantime you can try my version of GNATCOM which I adapted for
Ada2005 a while ago.

There should be done two fixes: first, remove "-gnatg" from Makefiles.
Second, search and replace "GNATCOM.Interface" to "GNATCOM.COM_Interface"

IIRC it was enough.



There is one problem, however: Win32API is indeniably harded to use in 
Ada compared to using WinAPI in Delphi, the same goes to GNATCOM. I have 
impression that the one who designed these binding generator have 
primarily used C++ (not counting Ada) and didn't have experience working 
with Delphi. As a consequence, GNATCOM is as hard to use as it is to use 
COM in C++.

At least, GNATCOM exists.

Indeed, I have used GNATCOM 3 years ago with these fixes with the
latest version of GNAT by that time and it worked fine.
