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
return (tMemRef.type<>#empty)
end
unfortunately both require 2 lines of code, I was hoping for a one-line
solution.
Cheers,
Valentin

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 > 0) -- only for dir < 10
return (not voidP(member(someName))) -- only for dir >=10
end
here's what I use:
on mGetMemType memref
if ilk(memref) <> #member then return #empty
return memref.type
end
if mGetMemType(member("something")) = #bitmap then ....
I didn't come up with a one-liner.
while I appreciate the fact, that lingo is much more consistent and
tidy since D10, I liked the old *sluggish* behavior of returning
always a member reference of type #empty regardless what.
since very much of my code relied on that I continued to use it via
my own "two line" check.
