## __COM_spsh_close__ - internal function: close a spreadsheet file using COM
## Author: Philip Nienhuis <prnienhuis@users.sf.net>
## Created: 2012-10-12
function [ xls ] = __COM_spsh_close__ (xls)
## If file has been changed, write it out to disk.
##
## Note: COM / VB supports other Excel file formats as FileFormatNum:
## 4 = .wks - Lotus 1-2-3 / Microsoft Works
## 6 = .csv
## -4158 = .txt
## 36 = .prn
## 50 = .xlsb - xlExcel12 (Excel Binary Workbook in 2007 with or without macro's)
## 51 = .xlsx - xlOpenXMLWorkbook (without macro's in 2007)
## 52 = .xlsm - xlOpenXMLWorkbookMacroEnabled (with or without macro's in 2007)
## 56 = .xls - xlExcel8 (97-2003 format in Excel 2007)
## (see Excel Help, VB reference, Enumerations, xlFileType)
## xls.changed = 0: no changes: just close;
## 1: existing file with changes: save, close.
## 2: new file with data added: save, close
## 3: new file, no added added (empty): close & delete on disk
xls.app.Application.DisplayAlerts = 0;
try

fname = xls.nfilename;

## Probably a newly created, or renamed, Excel file
## SaveCopyAs rather than SaveAs seems more robust w. Excel2007+
xls.workbook.SaveCopyAs (fname);

## Just updated existing Excel file
xls.workbook.Save ();
endif
xls.changed = 0;
xls.workbook.Close (fname);
