just starting a multiple form project

[Oliver1]

Okay a question which has been asked a million time before, but what is the correct way to access items ect between forms previously I've done this?

Public Class frmcall
    Inherits System.Windows.Forms.Form
    Dim form1 As Form1
 
    Private Sub frmcall_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        form1 = DirectCast(Me.Owner, Form1)
    End Sub
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        MsgBox(form1.BindingContext(form1.ds, "employees.SMS").Current())
 
        MsgBox(Form1.cbocompany.Text)
    End Sub
End Class

Which allows me to access all the components of Form1, just really want to check this is the correct way of doing it, as may as well get things right from the start.
