ActiveX in Ada?

ActiveX in Ada?

[Andreas]

Hello all!

Since it's possible to do DLL generation with Ada, the question now is: is
it possible to create ActiveX (OCX) controls in Ada??? The question
specifically goes for Aonix Object Ada, since it already can incorporate/use
existing ActiveX controls.
I would really like to leave the VB/VC++ realm for creating OCXs.

Thanks
Andreas

Isn't that a GNAT only solution?

Re: ActiveX in Ada?

[David Botton]

The questioner thought (wrongly) that perhaps Aonix Object Ada would be the
only solution since it supports ActiveX...... He just didn't realize the
current support for ActiveX on GNAT is superior.

Actually, GNATCOM - COM/DCOM/ActiveX/COM+/MTS/OLE2/OLE Automation support
for Ada - allows full use and creation of all the above buz words and much
more :-) If you use GWindows with GNATCOM you get the best support for
Graphical ActiveX use and development available....

In fact I created a GUI ActiveX control over year and half ago just using
GNATCOM. I decided to write GWindows in a large part to fill out areas of
ActiveX control programming (there is still are many great things to come in
that area as the GNavi - the Open Source Delphi/VB alternative - project is
starting to move forward)

Currently GNATCOM and GWindows are only on GNAT, but there is no technical
reason at this point to my knowledge that it could not be ported to any
other compiler.

Rational Apex on NT supports the GNATCOM bindings.

I'd like to know where one finds the typelibs that bindcom wants.
Bindcom on the great majority of .dll etc files I've tried seems
to result in "Error loading type library/DLL".

Re: ActiveX in Ada?

[Jeffrey Creem]

When running on a dll, the dll needs to be a COM or activeX dll. Not all
dlls are.

If you are out "looking" for components, try to find ones that say COM,
ActiveX or
sometimes VisualBasic (since it appears that it is more likely that when
someone provides
some service to VisualBasic they create it as a COM object).

As for the type library files (which can also be used)....They are rarer in
my experience.

The DLLs can actually be regular DLLs provided the author included a
typelib, but in practice, I've never seen that. A bit of a surprise as it
allows VB to also instantly bind to the DLL.

Another common extension for Activex is OCX instead of DLL

If you grab the latest snap shot of the development version of GWindows,
there is a new tool (GBManager) in it that allows you to view all the
registered libraries / COM objects on your system and bind to any one of
them with a few clicks. You will find that even on a clean install of 2K or
XP that there are hundreds on your system.
