>I am using the Tastrade's type of framework for my application. In the login form, which is created and run from the 'main::init()' method, I need to get access to an object that I created in the 'Application::Init()' class. The name of the object that I created is 'oRegistry'. The 'oRegistry' object is able to read and write data to the registry.

Joseph, how did you create it? CREATEOBJECT or AddObject?
If it is added to oApp object you should call it oApp.oRegistry.myMethod()
If it is created with CREATEOBJECT you need to make sure that oRegistry was declared as PUBLIC variable first, to be accessible from any place.
