Application Worksheet Function
Warns about late-bound WorksheetFunction calls made against the extended interface of the Application object.
An early-bound, equivalent function exists in the object returned by the Application.WorksheetFunction property; late-bound member calls will fail at run-time with error 438 if there is a typo (a typo fails to compile for an early-bound member call); given invalid inputs, these late-bound member calls return a Variant/Error value that cannot be coerced into another type. The equivalent early-bound member calls raise a more VB-idiomatic, trappable runtime error given the same invalid inputs: trying to compare or assign a Variant/Error to another data type will throw error 13 "type mismatch" at run-time. A Variant/Error value cannot be coerced into any other data type, be it for assignment or comparison.
