VBA - linking applications videos | What's the difference between early binding and late binding in VBA?

Posted by Andrew Gould on 15 April 2021

You may have written VBA code in Excel to reference another application by setting a reference to the application's object library. Did you know that you don't need to reference an application's object library to write code to control it? This video explains how to do this by switching from early binding to late binding in order to create a new Word document from Excel. You'll learn what changes you need to make to your code to allow this, how to use the CreateObject function and why late binding is so useful if you're sharing code with other people who may not be running the same version of an application as you.

See our full range of VBA training resources, or test your knowledge of VBA with one of our VBA skills assessment tests.
