com_load_typelib

(PHP 4 >= 4.0.7, PHP 5)

com_load_typelib — Loads a Typelib

Descrierea

bool com_load_typelib ( string $typelib_name [, bool $case_insensitive ] )

Loads a type-library and registers its constants in the engine, as though they were defined using define().

Note that it is much more efficient to use the Configuraţia la rulare configuration setting to pre-load and register the constants, although not so flexible.

If you have turned on Configuraţia la rulare, then PHP will attempt to automatically register the constants associated with a COM object when you instantiate it. This depends on the interfaces provided by the COM object itself, and may not always be possible.

Parametri

typelib_name

typelib_name can be one of the following:

The filename of a .tlb file or the executable module that contains the type library.
The type library GUID, followed by its version number, for example {00000200-0000-0010-8000-00AA006D2EA4},2,0.
The type library name, e.g. Microsoft OLE DB ActiveX Data Objects 1.0 Library.

PHP will attempt to resolve the type library in this order, as the process gets more and more expensive as you progress down the list; searching for the type library by name is handled by physically enumerating the registry until we find a match.

case_insensitive

The case_insensitive behaves in the same way as the parameter with the same name in the define() function.

In case any of you were wondering what com_load_typelib actually DOES, I have found that it loads constants\enums that the COM obeject has defined.  The example below is using the Nero COM object (from Nero Burning rom, version 6+).  The Nero object defines a bunch of constants, but they can not be used as PHP constants unless you use the mentioned function.  So the example below will work just fine:



<?php

$aNero = new COM("Nero.Nero") or die ("Nero didn't load, too bad");

com_load_typelib("Nero.Nero");

$aNero->GetDrives(NERO_MEDIA_CD);

?>



But this one will not, since PHP will return a message saying that the constant is undefined:



<?php

$aNero = new COM("Nero.Nero") or die ("Nero didn't load, too bad");

$aNero->GetDrives(NERO_MEDIA_CD);

?>



This one took me a while to figure out, hope it helps.

Hello PHP community, I want to help in a problem I found in this COM built-in function: com_load_typelib(), when I executed it in order to open a COM Server process (for example: Word, Excel, etc.) I was in trouble to release the object from memory, I figured it out, this is the solution:



Change a configuration in the php.ini:



; autoregister constants of a components typlib on com_load()

com.autoregister_typelib = true



When com.autoregister_typelib directive is true, PHP parser manage the COM server type library, I hope it helps.

<?php

// Some servers may have an auto timeout, so take as long as you want.

set_time_limit(0);



// Show all errors, warnings and notices whilst developing.

error_reporting(E_ALL);



// Used as a placeholder in certain COM functions where no parameter is required.

$empty = new VARIANT();



// Load the appropriate type library.

com_load_typelib('Word.Application');



// Create an object to use.

$word = new COM('word.application') or die('Unable to load Word');

print "Loaded Word, version {$word->Version}\n";



// Open a new document with bookmarks of YourName and YourAge.

$word->Documents->Open('C:/Unfilled.DOC');



// Fill in the information from the form.

$word->Selection->GoTo(wdGoToBookmark,$empty,$empty,'YourName'); // Note use of wdGoToBookmark, from the typelibrary and the use of $empty.

$word->Selection->TypeText($_GET['YourName']);



$word->Selection->GoTo(wdGoToBookmark,$empty,$empty,'YourAge');

$word->Selection->TypeText($_GET['YourAge']);



// Save it, close word and finish.

$word->Documents[1]->SaveAs("C:/{$_GET['YourName']}.doc");

$word->Quit();

$word->Release();

$word = null;

print "Word closed.\n";

?>



The example document is ...



Hello [Bookmark of YourName], you are [Bookmark of YourAge] years old.



and it would be called ...



word.php?YourName=Richard%20Quadling&YourAge=35



Regards,



Richard.
