[OLE::Storage_Lite::PPS](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS/markdown) is a class representing PPS. [OLE::Storage_Lite::PPS::Root](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3ARoot/markdown), [OLE::Storage_Lite::PPS::File](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3AFile/markdown) and [OLE::Storage_Lite::PPS::Dir](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3ADir/markdown) are subclasses of [OLE::Storage_Lite::PPS](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS/markdown). new() Constructor. $oOle = [OLE::Storage_Lite](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite/markdown)->new($sFile); Creates a [OLE::Storage_Lite](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3ARoot/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS/markdown)" object specified number $iNth. If $bData is true, the objects will have data in the file. Asc2Ucs() $sUcs2 = [OLE::Storage_Lite::Asc2Ucs](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3AAsc2Ucs/markdown)($sAsc>); Utility function. Just adds 0x00 after every characters in $sAsc. Ucs2Asc() $sAsc = [OLE::Storage_Lite::Ucs2Asc](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3AUcs2Asc/markdown)($sUcs2); Utility function. Just deletes 0x00 after words in $sUcs. [OLE::Storage_Lite::PPS](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS/markdown) [OLE::Storage_Lite::PPS](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3ARoot/markdown) [OLE::Storage_Lite::PPS::Root](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3ARoot/markdown) has 2 methods. new() $oRoot = [OLE::Storage_Lite::PPS::Root](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3ARoot/markdown)->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](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3ADir/markdown) [OLE::Storage_Lite::PPS::Dir](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3ADir/markdown) has 1 method. new() $oRoot = [OLE::Storage_Lite::PPS::Dir](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3ADir/markdown)->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](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3AFile/markdown) [OLE::Storage_Lite::PPS::File](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3AFile/markdown) has 3 method. new $oRoot = [OLE::Storage_Lite::PPS::File](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3AFile/markdown)->new($sName, $sData); $sName is name of the PPS. $sData is data of the PPS. newFile() $oRoot = [OLE::Storage_Lite::PPS::File](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite%3A%3APPS%3A%3AFile/markdown)->newFile($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](https://www.chedong.com/phpMan.php/perldoc/IO%3A%3AHandle/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/IO%3A%3AHandle/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite/markdown)" 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. ## COPYRIGHT The [OLE::Storage_Lite](https://www.chedong.com/phpMan.php/perldoc/OLE%3A%3AStorageLite/markdown) module is Copyright (c) 2000,2001 Kawai Takanori.
