Answer 1

You can create a Public Method on your second Form and Call it from your First Form. I created two Forms one with a TextBox and another with a ListBox, if you want anymore detail you will need to give an example of what the problem that you are having is.

Form1

Public Class Form1
    Dim frm2 As Form2
    Private Sub TextBox1_KeyPress(sender As System.Object, e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
        Dim tb As TextBox = CType(sender, TextBox)
        If e.KeyChar = vbCr Then
            If tb.Text.Length > 0 Then
                frm2.ListBoxAdd(tb.Text)
                tb.Text = ""
                e.Handled = True
            End If
        End If
    End Sub

    Public Sub New()

        InitializeComponent()
        frm2 = New Form2
        frm2.Show(Me)
    End Sub
End Class

Form2

Public Class Form2
    Public Sub ListBoxAdd(data As String)
        ListBox1.Items.Add(data)
    End Sub
End Class
