[Gambas-user] Gambas 3.1 and Exec (Bug or NOT?)

[Willy Raets]

Sebi, I'm afraid I need to go a little further than just testing for
their presence, I want to extract some information out of those commands
that are present.

The added source code (see previous mail) is part of the code of a
bigger library/component I'm building to extract all kind of information
from a system (like window manager, desktop, memory and so on).

Need this for my distributed applications to determine what they are
running on for trouble shooting the applications.

Making it into a library/component so other Gambas developers can
benefit from it as well.

And that all worked fine in both Gambas 2 and Gambas 3.0 (as I am
writing it for both Gambas version). Problems started with Gambas 3.1,
but according to Benoit the 3.0 implementation was the buggy one (so I
guess the Gambas 2 implementation is buggy as well)

So I have recoded it to now work with Gambas 3.1 using TRY and it does.
But now another problem occurs. Seems that some sub process doesn't
kill.

Thanks anyway
