what does mean late binding

what does mean late binding.

Hi,

Binding the Object Library in the code at runtime is Late Binding.
Usually achieved through CreateObject or GetObject functions.

Generally Late binding is slower than Early binding but the bigger picture is that Late binding is better when code has to be distributed.

Late binding is a mechanism where the method being called upon an object is looked up by name at runtime. GetObject or CreateObject functions are used to achieve late binding.Most script languages use late binding.It makes use of a lookup which takes longer time because its not a simple offset calculation, there are usually text comparisons to be made.
