Early & Late Binding

Late binding makes it possible for you to declare a variable as an Object or a Variant data type. The variable is initialized by calling the GetObject or CreateObject function and specifying the application's programmatic identifier. For example, in the following code fragment, an Object variable is declared and then set to an instance of Microsoft® Access by using the CreateObject function:

Early binding makes it possible for you to declare an object variable as a programmatic identifier, or class name, rather than as an Object or a Variant data type. When you are using early binding, you can initialize the object variable by using the CreateObject or GetObject function or by using the New keyword if the application supports it.
