' some data and save it to another XLS file (Tutorial37 - read XLS file.xls).
'----------------------------------------------------------------------------Imports EasyXLS
Imports System.IO
Module Tutorial37
Sub Main()

' Create an instance of the class that reads Excel filesDim workbook As New ExcelDocument
' Read XLS file
Console.WriteLine("Reading file C:\Samples\Tutorial28.xls." & vbCrLf)
If (workbook.easy_LoadXLSFile("C:\Samples\Tutorial28.xls")) Then' Get the table of data for the second worksheetDim xlsSecondTab As ExcelWorksheet = workbook.easy_getSheet("Second tab")
Dim xlsSecondTable = xlsSecondTab.easy_getExcelTable
' Write some data to the second sheet

For column As Integer = 0 To 4
xlsSecondTable.easy_getCell(1, column).setValue("Data " & (column + 1))
