Hi Bruce,
I have successfully used this code which is from Jussi Lahtinen. I built
it into two of my applications, and it works reliably, at least under
Gambas2 on our somewhat older system:
PUBLIC SUB Form_Open()
DIM sOutput AS String
EXEC ["pgrep", "-f", "-l", "-u", System.User.Name, "Stein3.gambas"]
WAIT TO sOutput
IF Split(Trim$(sOutput), gb.NewLine).Count > 1 THEN
QUIT
ENDIF
Just replace "Stein3" by your binary's name.
Regards
Rolf
