Description
DoFunction is called whenever a variant method that returns a result needs to be invoked. The Dest parameter points to the location where the result of the function must be placed; the result must be a variant value.
V is the variant on which the method is being executed. The Name is the name of the function to execute, and Arguments is an array of variant arguments that were passed to the function.
The function must return True if the function was executed correctly, False otherwise.
