well sorry for that i figured it out when i looked at the code better

for anyone who would like to know the cure for a delete button for this code is

Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click        Dim m_index As Integer
        m_index = ListBox1.SelectedIndex
        BindingSource1.RemoveAt(m_index)




    End Sub

change the button8_Click to what your button is and it will work

m_index = ListBox1.SelectedIndex
BindingSource1.RemoveAt(m_index)

BindingSource.RemoveCurrent method would do the same thing. BindingSource Methods (System.Windows.Forms)
