In this beginner vb.net tutorial I will demonstrate how to use the Multi Document Interface, or “MDI Forms” to create a form within a form effect in your application.

Additionally, I will demonstrate how these forms can communicate with each other and how you can access the mdiContainer to manipulate batches of child forms.
