Perform Action In Form1 When Form2 Exits

(Visual Basic .NET)

I think this should be fairly simple, but I don’t know the right commands for it. What I want to do is have Form1 be the main program, when you click a button it opens Form2. The user then inputs information into Form2 and clicks a “Save” button.

When Form2 closes, I want Form1 to run some specific code. How do I do this?
