Sharing info between forms

I have a question, I have to make a few programs for my class which I can't find decent documentation in my book for (ITT Tech, go figure)

Say I have my main form (Form1), when you press a button on form1, it opens a new form (form2) that has a text input box, you enter a number, it does its calculation and must send it's calculation to a label box in Form1. how do I do this? And does this work the same way for outputting it in a listbox (insted of a label box)?

do a forum search, this question is asked almost daily and has been answered over and over.

You can see my solution to this commom problem here:

Hope that helps.

vb Code:

'Write this code in form1, button1_click event        
Dim frm As New Form2
frm.Show()
 
'Add a textbox and a command button in form2 and write the following code in form2 button_click event
 
Dim frm As New frmAddCtrl
        frm.Show()
        frm.Label1.Text = TextBox1.Text
        Me.Hide()
