Hi Graham,
I seem to be forever stuck in a half-understanding of Transcript/Revo. The latest problem is that I want to do an existence test for a particular custom property. I already know I can't script"customkeys" is the magic word :-)
if exists(the myOddProperty of image "thing" of this cd) then...
as someone has already explained to me that a property is not an object, and so in this rather technical sense doesn't exist. My next attempt was to
get the customProperties of image "thing" of this cd
if "myOddProperty" is in it then...
This doesn't work either, presumably because the customProperties is an array, although you would have thought that the indices of an array (element references) would be in there somewhere. There is not that much about arrays in the documentation (the entry under ']' in the Transcript Dictionary is quite useful, but it took some finding).
I then tried
get the customProperties of image "thing" of this cd
if exists(it["myOddProperty"]) then...
But that doesn't work either (I suppose an array element isn't an object).
I'm sure the answer is simple, but I can't find it. Help appreciated.
TIA
Graham

if (lineoffset("myOddProperty",the customkeys of img "thing") <> 0) then
## do your stuff here
end if
...
Hope that helps.
