Pass values to a SetTimer function? Topic is solved

[j46]

as @boiler already said, AHK v2 does not support "super-global variables" any more. But you can achieve a comparable effect if you replace them with properties of an object define in the global scope:

@just me, I ran into this issue today while trying to use objects, are there any trix here or is this a limitation with objects ?

Code: Select all

PIDs := {vlc:"0"} 
run 'vlc.ahk', "D:\Albin\Code\Autohotkey\Autohotkey scripts\Scripts_v2\",,&PIDs.vlc

i get the error ==> "&" requires a variable

@j46,
it's a limitation. You need to use a variable as temporary target in such case.

I think you could do that with no issues if the property held a variable reference (VarRef) and then dereferenced it outside after giving it to run, but it looks kinda murky and verbose creating var refs on the spot like that. Going by some post I stumbled years ago from lexikos, the reference count on the VarRef would be decreased properly once the original var goes out of scope from the fat arrow, I haven't checked to see if there are other implications.

Code: Select all

PIDs := { vlc: ((ref?)=>&ref)() }

run 'vlc.ahk', "D:\Albin\Code\Autohotkey\Autohotkey scripts\Scripts_v2\",, PIDs.vlc ; no "&" here

msgbox(%pids.vlc%)

pids.vlc := %pids.vlc% ; should release the last reference and leave the var ref to be collected.

thx coffee, I have to look into VarRefs
