Should be...

        Dim dt As New DataTable()
        objDB = New DatabaseToExcel.DB(ConnectionString)
        dt = objDB.runQuery(query)
        ctl_progress.Visible = True
        ctl_progress.Minimum = 1
        ctl_progress.Maximum = dt.Rows.Count + 1
        ctl_progress.Value = 1
        ' This is to access the first work sheet of your application
        sheet = CType(book.Worksheets(1), Excel.Worksheet)
        sheet.Name = "SampleExcel"
        For i As Integer = 1 to dt.Rows.Count
            For j As Integer = 1 to dt.Columns.Count
                ' This is to add the Data which retrieved from
                ' the database into your Excel Sheet.
                CType(sheet.Cells(i,j), Excel.Range).Value2
                                   = dt.Rows(i-1).ItemArray(j-1).ToString()
                'dt.Rows[i-1].ItemArray[j-1].ToString()--> This will retrieve
                ' data from your datatable's
                '(i-1)th rows (j-1)st column
            ctl_progress.Value = ctl_progress.Value + 1
        MessageBox.Show("Your Process Completed Successfully")
        ctl_progress.Visible = False
    Catch e1 As Exception
    End Try
