Using Win32Com with Ada

Using Win32Com with Ada

[cedric]

Hi All,

I would like to use the Win32Com interface in Ada. Can anybody give me
a hint how to do it and where to find information about it?

I just got the advise to wait for GNAT GPL 2009, maybe you should
aswell.

Some time ago I tried to get GNATCOM working, but I failed.

It could be the same problem as GWindows: it works, but the installer 
doesn't on recent GNATs, so you need a pre-built source and tool set 
(*). A workaround is to build it with GNAT 3.15p, then use the stuff 
with any newer GNAT (for GWindows, this trick works through 2008 GPL at 
least).

(*) or be patient: the repackaging of GNATCOM and GWindows are in 
progress; perhaps the svn version is usable.

I'm doing some migration from VC to GNAT, and writing my own binding of 
DirectShow (pure COM based) is not that hard.

Someone should compose a tool to convert C header files to GNAT's ads, I'm 
just lazy doing so as I've done more of my jobs manually ...

This is currently part of GNATPro
just "g++ -c blaa.h -fdump-ada-spec" or "gcc -c blaa.h -fdump-ada-spec" 
and out comes blaa_h.ads.
Suppose that wil be part of GNAT GPL 2000

It seems -fdump-ada-spec does not work quite well with header files come 
with Windows SDK - does anyone have any good experience to share? 
Specifically, I was trying to roll out DirectShow specification but 
encountered way too many errors.

I haven't tried yet but I assume it works fine on *nix or header files 
targeting gcc, anyway Windows is just 2nd (maybe 3rd) tier platform for 
most open source projects.
