Hello and thanks in advance!
I am trying to find a way to determine whether or not a particular attribute
of a shared object exists, using Lingo. Here's the sample code:
-- this part works fine
tSharedObject = newObject("SharedObject", FALSE)
gsoConfig = tSharedObject.getLocal("dfcookie")
-- here's where the problem begins. To check whether or not
-- configInfo exists as a slot (or attribute) in the shared object, I tried
this, with the idea that
-- I would test the tConfigInfo variable to see if it is VOID or not:
tConfigInfo = gsoConfig.data.configInfo
-- but this syntax generates a script error in Lingo, if configInfo doesn't
exist. So next, I tried the old bracket trick, like -- this:
tConfigInfo = gsoConfig.data[#configInfo]
-- but this always returns a null, even if configInfo actually exists. So
this won't work either. It appears that brackets don't work with shared
objects referenced in Lingo.
So, is there a way to determine what the slots are in a Lingo-referenced
shared object? Even a way to get a list of all the slots? Or the number of
slots?
Thanks for your help!
