Backticks and timeouts

ruby-talk
1

I've never used Ruby before but need to try something tonight for sorta
presentation tomorrow.
The extent of my Ruby code is inside of RPG Maker XP (last minute thing
had like 1 day to show my idea) and when someone walks over a certain
tile it executes
result = `notepad.exe`

That's it. Problem is RPG Maker then times out if I don't immediately
close the notepad window. Is there any way to execute notepad.exe
without actually expecting a result back? Just launch and forget about
it?

try IO.popen.

eg, try running the ff,

#--code
io1= IO.popen "notepad.exe"
5.times do puts "i am here" end
io2= IO.popen "notepad.exe"
5.times do puts "i am here again" end
#--code

the above will invoke 2 instances of notepad and also run the 2 loops (no pause there).

(note, you may also use win32ole w wsh if you want to fully control notepad[eg if you want to send keystrokes to it])

hth.

Kind regards -botp

io1= IO.popen "notepad.exe"
