I guess you could use arrayEncode() first and then get an MD5digest of the
data.


This command works great.
Many Thanks! :-D

How about copying the objects to the clipboard and then querying the
clipboardData["objects"].


I am not sure how I could use this code
to compare the properties of two controls.

How about comparing the properties arrays of the two controls

In the following example I simply created two identical buttons on a blank stack. They should be identical in almost every respect, the exceptions being their ids their rects and their layers. If you put the properties array of each object into separate variables and delete the elements for those three properties from each variable then the two variables should be equivalent.

on compareProps
   put the properties of btn 1 into t1
   put the properties of btn 2 into t2
   delete variable t1["id"]
   delete variable t2["id"]
   delete variable t1["rect"]
   delete variable t2["rect"]
   delete variable t1["layer"]
   delete variable t2["layer"]
   put t1 = t2
end compareProps

Alternatively, you could simply iterate through the keys of the properties of the two objects and compare the values of the individual properties.

Terry...



Thanks again for your help!
