What are properties, what are methods?

As described in the context of the description of the Object Model (see What is meant by the term "object model?"), once an object has been created, the Visual Basic program then has access to the properties and methods contained in that object. Properties can be mostly thought of as variables, methods can be mostly thought of as subroutines or functions that perform certain operations or computations inside the respective application object. For an illustration of how to "navigate" the hierarchy of objects and how to access various properties and methods, see the example in How can I change the font (or other aspects) of numbers in spreadsheets?.
