Hi, I have two instances of a DataGridView each bound to the same callbacks within Lisp. The callbacks each have two parameters, the first of which is a C# object. This object corresponds to the DataGridView that initiated the event. When I create the two DataGridViews I put them both into a list and when a callback is called I look through my list to match up the first parameter with one of the references in my list. However this is failing. How do I compare references to C# objects using RDNZL? I've noticed that there is an enum-to-int function which allows enums to be compared in Lisp. I may need something like this to compare the identity of objects in Lisp. Another approach would be to write a function in C# to compare object identity but I don't want to include a dll in my little example. Any help would be appreciated. Regards, Matthew
