NAME 🖥️ OLE_Storage_Litepm 🖥️

Simple Class for OLE document interface.

SYNOPSIS

use OLE::Storage_Lite; # Initialize. # From a file my $oOl = OLE::Storage_Lite->new(“some.xls”); # From a filehandle object use IO::File; my $oIo = new IO::File; $oIo->open("<iofile.xls"); binmode($oIo); my $oOl = OLE::Storage_Lite->new($oFile); # Read data my $oPps = $oOl->getPpsTree(1); # Save Data # To a File $oPps->save(“kaba.xls”); #kaba.xls $oPps->save(-); #STDOUT # To a filehandle object my $oIo = new IO::File; $oIo->open(">iofile.xls"); bimode($oIo); $oPps->save($oIo);

DESCRIPTION

OLE::Storage_Lite allows you to read and write an OLE structured file.

OLE::Storage_Lite::PPS is a class representing PPS. OLE::Storage_Lite::PPS::Root, OLE::Storage_Lite::PPS::File and OLE::Storage_Lite::PPS::Dir are subclasses of OLE::Storage_Lite::PPS.

new()

Constructor.

$oOle = OLE::Storage_Lite->new($sFile);

Creates a OLE::Storage_Lite object for $sFile. $sFile must be a correct file name.

The new() constructor also accepts a valid filehandle. Remember to binmode() the filehandle first.

getPpsTree()

$oPpsRoot = $oOle->getPpsTree([$bData]);

Returns PPS as an OLE::Storage_Lite::PPS::Root object. Other PPS objects will be included as its children.

If $bData is true, the objects will have data in the file.

getPpsSearch()

$oPpsRoot = $oOle->getPpsTree($raName [, $bData][, $iCase] );

Returns PPSs as OLE::Storage_Lite::PPS objects that has the name specified in $raName array.

If $bData is true, the objects will have data in the file. If $iCase is true, search is case insensitive.

getNthPps()

$oPpsRoot = $oOle->getNthPps($iNth [, $bData]);

Returns PPS as OLE::Storage_Lite::PPS object specified number $iNth.

If $bData is true, the objects will have data in the file.

Asc2Ucs()

$sUcs2 = OLE::Storage_Lite::Asc2Ucs($sAsc>);

Utility function. Just adds 0x00 after every characters in $sAsc.

Ucs2Asc()

$sAsc = OLE::Storage_Lite::Ucs2Asc($sUcs2);

Utility function. Just deletes 0x00 after words in $sUcs.

OLE::Storage_Lite::PPS

OLE::Storage_Lite::PPS has these properties:

No
Order number in saving.

Name
Its name in UCS2 (a.k.a Unicode).

Type
Its type (1:Dir, 2:File (Data), 5: Root)

PrevPps
Previous pps (as No)

NextPps
Next pps (as No)

DirPps
Dir pps (as No).

Time1st
Timestamp 1st in array ref as similar format of localtime.

Time2nd
Timestamp 2nd in array ref as similar format of localtime.

StartBlock
Start block number

Size
Size of the pps

Data
Its data

Child
Its child PPSs in array ref

OLE::Storage_Lite::PPS::Root

OLE::Storage_Lite::PPS::Root has 2 methods.

new()

$oRoot = OLE::Storage_Lite::PPS::Root->new( $raTime1st, $raTime2nd, $raChild);

Constructor.

$raTime1st, $raTime2nd are array refs with ($iSec, $iMin, $iHour, $iDay, $iMon, $iYear). $iSec means seconds, $iMin means minutes. $iHour means hours. $iDay means day. $iMon is month -1. $iYear is year - 1900.

$raChild is a array ref of children PPSs.

save()

$oRoot = $oRoot>->save( $sFile, $bNoAs);

Saves information into $sFile. If $sFile is ‘-’, this will use STDOUT.

The new() constructor also accepts a valid filehandle. Remember to binmode() the filehandle first.

If $bNoAs is defined, this function will use the No of PPSs for saving order. If $bNoAs is undefined, this will calculate PPS saving order.

OLE::Storage_Lite::PPS::Dir

OLE::Storage_Lite::PPS::Dir has 1 method.

new()

$oRoot = OLE::Storage_Lite::PPS::Dir->new( $sName, [, $raTime1st] [, $raTime2nd] [, $raChild>]);

Constructor.

$sName is a name of the PPS.

$raTime1st, $raTime2nd is a array ref as ($iSec, $iMin, $iHour, $iDay, $iMon, $iYear). $iSec means seconds, $iMin means minutes. $iHour means hours. $iDay means day. $iMon is month -1. $iYear is year - 1900.

$raChild is a array ref of children PPSs.

OLE::Storage_Lite::PPS::File

OLE::Storage_Lite::PPS::File has 3 method.

new

$oRoot = OLE::Storage_Lite::PPS::File->new($sName, $sData);

$sName is name of the PPS.

$sData is data of the PPS.

newFile()

$oRoot = OLE::Storage_Lite::PPS::File->newFile($sName, $sFile);

This function makes to use file handle for getting and storing data.

$sName is name of the PPS.

If $sFile is scalar, it assumes that is a filename. If $sFile is an IO::Handle object, it uses that specified handle. If $sFile is undef or ‘’, it uses temporary file.

CAUTION: Take care $sFile will be updated by append method. So if you want to use IO::Handle and append a data to it, you should open the handle with r+.

append()

$oRoot = $oPps->append($sData);

appends specified data to that PPS.

$sData is appending data for that PPS.

CAUTION

A saved file with VBA (a.k.a Macros) by this module will not work correctly. However modules can get the same information from the file, the file occurs a error in application(Word, Excel …).

DEPRECATED FEATURES

Older version of OLE::Storage_Lite autovivified a scalar ref in the new() constructors into a scalar filehandle. This functionality is still there for backwards compatibility but it is highly recommended that you do not use it. Instead create a filehandle (scalar or otherwise) and pass that in.
