hi list,
does anyone know a way to check for the existence of a member with a
given name that works for both dmx and dmx2004?
I know the following 2 methods, but it would be nicer to have a
consistent method for all versions:
on memberExists (someName)
return (member(someName).membernum
on memberExists (someName)
return (member(someName).membernum 0) -- only for dir 10
return (not voidP(member(someName))) -- only for dir =10
end
Here's the obvious/ugly way that you probably would like to avoid:
on memberExists (someName)
if the scriptExecutionStyle 10 then return
Would this work?
put ((member does not exist).number 0)
-- 0
Nope, that will fail if the scriptExecutionStyle is set to 10 as the
invalid member reference returns VOID, and VOID does not have a number
property and so a script error will occur. The problem here is that
prior to MX'04 all the

In MX 2004, (member does not exist).number returns a script error on my
machine (Win XP). I think that's because member(does not exist) returns void.
This has come up before, and we've flogged it

Thanks Alex.
So we have the following 2 equivalent methods to check for existence of
a member that work for all dir version:
on memberExists (tMemRef)
if voidP(tMemRef) then return FALSE
return (tMemRef.number 0)
end
on memberExists (tMemRef)
if ilk(tMemRef)#member then return FALSE
