Class module B is a function base class with function prototypes for use by the solver. Class module C is an override of B which has the actual implementation of function(s)/subroutine(s) for the solver. I call class A with reference to class C, and the solver thus knows which ...
Stores the previous state of anything that (possibly) needs to be undone Sets a sub to be run when the user selects undo Write that subroutine, which reverses the changes last made by your code. In this article I will demonstrate how one can use two class modules to create a (more or...
