In Right hand side . .. a normal textbox
Set your textbox's MultiLine property to True. Then do this:
TextBox1.Text = ""
For Each item As Object In ListBox1.SelectedItems
TextBox1.Text &= item.ToString & vbNewLine
Next
Oh, you want to limit 15 items in your textbox, do this:
Private Sub ListBox1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
TextBox1.Text = ""
For Each item As Object In ListBox1.SelectedItems
If TextBox1.Lines.Length = 15 Then
Exit For
End If
TextBox1.Text &= item.ToString & vbNewLine
Next
End Sub

why don't you use a second ListBox..Then your Code would like this:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim item As Object
Me.ListBox2.Items.Clear()
item = ListBox1.SelectedItem()
For Each item In Me.ListBox1.SelectedItems
Me.ListBox2.Items.Add(item)
Next
End Sub
