Some libraries load other libraries as part of there functionality. For example Crystal Reports Object Factory uses the CreateObject() method to create an instance of a Crystal Design RunTime Application. If you want to use constants defined in the newly loaded library, you will need to manually register the library. Even with com.autoregister_typelib set to true.



<?php

echo 'com.autoregister_typelib = ', ini_get('com.autoregister_typelib'), PHP_EOL;



$o_CrObjectFactory = New COM('CrystalReports11.ObjectFactory.1');



$o_CrApplication = $o_CrObjectFactory->CreateObject("CrystalDesignRunTime.Application");



echo 'Will not be defined : ', crOpenReportByDefault, PHP_EOL;



com_load_typelib('CrystalDesignRunTime.Application');



echo 'Will now be defined : ', crOpenReportByDefault, PHP_EOL;

?>



outputs ...



com.autoregister_typelib = 1

Will not be defined :

Notice: Use of undefined constant crOpenReportByDefault - assumed 'crOpenReportByDefault' in C:\refl.php on line 8

crOpenReportByDefault

Will now be defined : 0

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.
