Saving ComboBoxes and TextBoxes to an Excel book

Hi,
Can someone please help me on how to save textboxes and comboboxes to an excel workboook?

The current Code that I have is:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        TextBox1.Text = objWorksheet.Cells(1, 1).text
        TextBox2.Text = objWorksheet.Cells(2, 1).text
        TextBox3.Text = objWorksheet.Cells(3, 1).text
        objExcel.Workbooks.Close()
        objExcel.Application.Quit()
    End Sub

But this code does not work...
