Identify forms by their methods

I am writing a script to compare builds of the same application. It exercises each menu option then notes the form, dialog or application that opens. The form is sometimes a different application and not necessarily a child of the application being tested.

I want to be able to identify the form object.

Currently I am looking for the system object that has focus



set focusObject = sys.findchild("Focused", TRUE, 100)



As this could be a button on the form, and not the form itself, I then want to loop up through parent objects until I find one with a close method.

Is there a way to test an object to see if it has a particular method?

Is there a better way of doing this altogether? Something like sys.Desktop.ActiveWindow or sys.Desktop.FocusedWindow but for a form or dialog.
