It seems I'm unable to define those properties. I tried :
Dim wbk As Aspose.Cells.Workbook
Dim wks As Aspose.Cells.Worksheet
Dim index As Integer
wbk = New Aspose.Cells.Workbook
index = wbk.Worksheets.Add(Aspose.Cells.SheetType.Worksheet)
wks = wbk.Worksheets(index)
wks.PageSetup.PrintArea = "A1:B10"
But when I open the file the print area is not defined. What am I missing ? I'm using the 188.8.131.52 hotfix as I had a problem with the WorkBook.Combine method...
Thanks in advance.
