What's the best way to calculate the length of a Dictionary object in Flex?
var d:Dictionary = new Dictionary();
d["a"] = "alpha";
d["b"] = "beta";
I want to check the length which should be 2 for this Dictionary. Is there any way to do it other than looping through the objects?

No, there is no way to check the length of an object(Dictionary is pretty much an object that supports non-String keys) other than looping through the elements.

You probably don't have to worry about checking if the property is an internal one.
