I am wondering how to use excel's automated reference to automate updating
data in a excel file using access.

Ex: Using the ".Range("G9").Value ="

I have personally tried using this code (it did not work)

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

With objExcel
.Visible = True
.Workbooks.Open("\EDV SUMMARY SAMPLE.xls")
*.Range("G9").Value = Val(EDV_DMM_STD_SummaryDataGridView(3,1))*
.Range("A1").ColumnWidth = 20
.Range("A1").Font.Bold = True
.Range("A2").Value = "So. Main St."
.Range("A3").Value = "Hartford" & ", " & "CT"
End With

**this is a control table conected to a linked databse. I am trying
to point to a cell in the table by using indexes and write the data to the
excel doc.
