>If I place a class on a form I can easily change the code for a method or event. If I instantiate a class using CREATEOBJECT() in code, how do I make the same code changes to a method or event?

You cannot change the method code of the object created at runtime. However, there is a workaround. If you add the line calling the program into your class method code at design time, then you may dynamically create the necessary code in PRG on the fly at runtime and compile it.

* myclass.somemethod()

*** some method code
DO myprg1
*** more method code
