[Gambas-user] How prevent application from opening twice

[Jussi Lahtinen]

Hi!

I have looking for code to do that also... but your code doesn't work with me.
It always finds two instances of my program;
1. the program it self
2. sh -c pgrep -f -l ProgramName  (option -l is just for debugging, it
doesn't matter)

This happens with Gambas 2.10 at Ubuntu 8.10 64bit.

This did NOT fix the problem:
SHELL "pgrep -f -l " & Application.Args[0] WAIT TO sShellOutput

But this works:
Exec ["pgrep", "-f", "-l", Application.Args[0]] To sShellOutput

And just for case:
Exec ["pgrep", "-f", "-l", Application.Args[0]] Wait To sShellOutput

So, just to warn, and thanks for idea!


Jussi
