One method is to set a private form level variable as shown below. After the form is shown the variable is set to false which prevents the form from being shown again.

Private ShowForm2 As Boolean = True
Private Sub cmdShowForm_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdShowForm.Click

    If ShowForm2 Then
        Dim f As New Form2

        Try
            f.ShowDialog()
        Finally
            f.Dispose()
        End Try
        ShowForm2 = False
    End If

End Sub
