Excel Add-in ribbon button click event

I'm trying to create an Excel Add-in that consists on a new ribbon tab with custom buttons.

I would like that, for example, when I click on a button on the ribbon, to write something to an already open Excel sheet, like the code that I show below, but with this code, I get the error that I show on the attached picture.

What am I missing here?


Imports Microsoft.Office.Tools.Excel

Public Class Ribbon1

    Private Sub btnInserirLinha_Click(ByVal sender As System.Object, ByVal e As Microsoft.Office.Tools.Ribbon.RibbonControlEventArgs) Handles btnInserirLinha.Click
        Dim objExcelApp As New Excel.Application
        Dim objExcelBook As Excel.Workbook
        Dim objExcelSheet As Excel.Worksheet

        objExcelBook = objExcelApp.ActiveWorkbook
        objExcelSheet = objExcelBook.ActiveSheet
        objExcelSheet.Cells(1, 1) = "Teste"

    End Sub
End Class

Open in new window

if you are using VSTO:
Replace line 6 with:
 Dim objExcelApp As Excel.Application = Globals.ThisAddIn.Application

See my tutorial: (It is C# but it is easy to translate to VB.net)
