How to find the last drawn object with description?

Hi

i'm actually trying my first steps with creating an EA and i'm struggling with a simple function: how do i find the last drawn object within a window?
ObjectName(0); gives me an Object somewhere within the window but not the last one...should be quite simple but i can't figure it out

int obj_last=ObjectName(0);

string name;
string description;

name=obj_last
description = ObjectDescription(name);


string temp = "EA\n";
temp = temp + "------------------------------------------------\n"
+ " " + name + "\n"
+ " " + description + "\n"
+ "------------------------------------------------\n";

Comment(temp);

just keep a list of names of the objects you know to exist, then when you iterate through the list of objects in the window and can't find the same name in your list then you know you have a new object or objects recently added. add them to your list.

once you have found any new items you also need to search your list for objects that no longer exist and remove them from your list.

simple enough.

Thank you ....
