ActiveX Controls

[Thomas Krueger]

Hello,

i got a problems using COM objects in Ada. The first thing i tried to do has 
been  to read the article from David Bottom"Interfacing Ada 95 to Microsoft 
COM and DCOM Technologies". Pretty good article for understanding, but i 
think it is to much work for many more functions. I am looking for a 
solution similar to the C++ visual studio. Where i can import the classes 
easily ...

I found GNATCOM and the desrciptions are well. But i was not able to finish 
the install procedure using the free ada2005 gnat compiler. Maybe the 
problems with the installation is another topic

Another one is Object ada from Aoinix (the demo version) but this version 
does not support activeX. Does the fully licensed product support activeX 
well? (like the c++ ms visual studio)

Which way would you prefer? Is there another one?

Thanks in advance
Thomas

hi,Thomas:
A new keyword,"interface",has been added to ada2005.
you must check out a new version Gnatcom from CVS to fix the problem

Hi,

thank you for your email. Can you help me again? Iextracted the archive and 
tried to install gnatcom by following the instruction in the readme.txt. 
Instead off calling the install bat I entered the following command:

C:\Programme\gnavi\gnatcom>gnat make makefile

after that I recieved the following error messages

gcc -c -x ada makefile
makefile:1:01: compilation unit expected
makefile:26:10: illegal character
makefile:33:30: illegal character
makefile:50:24: illegal character
gnatmake: "makefile" compilation error

the gnavi/gnatcom is in the path in autoexec.bat

Sorry, but i dont know what to do to make it run. A longer time ago i've 
written simple programm using the gwindows. At that time the installtion 
using the old gnat 3.15p succeeded without any problems.

Thank you
Thomas

It looks like the makefile is taken as an Ada source.
Did you try just "make" ?
I remember doing the exercise with GNATCOM / GWindows and GNAT
post-3.15p.
IIRC the main gotcha is the disappearance of use of registry (GNATReg)
after 3.15p;
you have put the GNATCOM and other such sources in the library tree and
go with .gpr files for referencing subdirs, sources etc; the best is to
mimic the Win32 bindings (again, IIRC).

@Bubble: The archive you gave me is working. With the things you gave me 
there is no need for "installing".

@Gautier, thank you too. I am going to try your way to install the gnatcom 
by my own.

Thanks a lot
Thomas

Thomas,
check your environment configuration and source code is correct.
    1. ADA_SOURCE_PATH,ADA_INCLUDE_PATH environment variables should include 
%GNATCOM HOME% \ framework
    2. PATH variable should be include %GNATCOM HOME% \tools



"compilation unit expected"
"illegal character"

check your souce to sure there is no invisible illegal character in your 
source code and do not forget delete all *.o and *.ali in building path.
in some case,clean build will solve some unknown problem.
