[Gambas-user] Re: Overload the form close?

[Andre Saccomani]

Thanks Benoit, It worked perfectly.

Now going off-topic. can you help me on more time? More difficult this time.

I dont want to allow two instances of my program running at the same time.
So I want to check if my program is already running. If so, I do not want to
allow a second instance. This part is easy to be achieved, so let me move
forward:
Is there anyway to send a signal to a linux PID? and if so, is there a way
to catch these signals in a gambas application? So when I try to open a
second instance of my program, it would check if is there one already
running and then it could send a signal to the first instance before exit.
This signal would cause my program (the first instance) do do a dlgMain.Show,
or something like this. restoring it from tray.

I'm not sure if this is possible using gambas, but if possible, can you give
a tip of how to achieve that?

Thanks in advance,
Andre
