Visual Basic

Okay guise.
I'm making a program, and I have no idea what the fuck I'm doing. So it's fun.
I want to make a button, and when you click it, an information box pops up. I placed the button. How do I code it to write what I want?

Double click the button, in the coding type, MessageBox.Show("Message","Title",MessageBoxButtons.OK,MessageBoxIcon.Information)
