Just to sum up the permissions I had to set in DCOMCNFG I have written a short
text on the subject. I am posting it here in case others need it for reference.
Since the server does not accept mails larger than 40kb I am unable to post the
Word document with snapshots of the dialogs. I hope the text alone will suffice
though.
Best regards,
Mats Bjerin

I have been experimenting for a couple of days using the COM object to call
functions inside Word 2000. I was constantly receiving an error about a “NULL
pointer exception” when trying to instantiate the Word object using the line:
$oWord = new COM("Word.Application") or die("Unable to instantiate Word");
taken from the example application kindly provided by Alain M. Samoun.
I am running Windows 2000 SP2, PHP 4.0.6 under IIS V5.
By reading through the forums on the PHPBuilder site I finally found a reference
to the application DCOMCNFG.EXE, which sets permissions for COM and DCOM
objects, under Windows. This was to be my “salvation”.
Others seem to receive the following message indicating the same problem under
different versions of PHP:
Warning: Unable to obtain IDispatch interface for CLSID
> {000209FF-0000-0000-C000-000000000046}: Access is denied. in
> C:\Inetpub\wwwroot\website\excel\word.php on line 3
> Unable to instantiate Word
Many thanks to the following people who through their discussions and advice to
each other solved my problem:
Alan Brown <[EMAIL PROTECTED]>
Mize, Robert <[EMAIL PROTECTED]>
To make Alain’s program work fully on my server the following conditions applied
at the time of my successful tests:
· I have IIS5 installed.
· I have Office 2000 SR-1 installed (obviously with Word 2000 i.e. V9) on the
server (the client installation of Word has nothing to do with the PHP-script
executing on the server).
· I have run the program DCOMCNFG.EXE and have changed the following permissions
for the Microsoft Document object from their default settings:
- Custom Access Permissions: “Allow” the “IUSR_<servername>” user access to the
object.
- The user account to run the application: “The interactive user”
· I am using Alain’s script (my version is displayed at the end of this document
for reference) installed in the wwwroot directory on the server.
For reference I am including my copy of Alain’s program:
<?php
$sNL = "<BR>\n";
print "Hello wor(l)d!{$sNL}";
#Instantiate the Word component.
$oWord = new COM("Word.Application") or die("Unable to instantiate Word!");
#Get and print its version.
print "Loaded Word, version {$oWord->Version}{$sNL}";
#Another way to get the version using com_get.
$testversion = com_get($oWord->application,version);
print "Version using Com_get(): $testversion {$sNL}";
#Make it visible in a window.
$oWord->Visible = 1;
#Open a new document.
$oWord->Documents->Add();
#Write something.
$oWord->Selection->TypeText("This is a test...");
#Now save the document.
$oWord->Documents[1]->SaveAs("Useless test.doc");
#Comment next line if you want to see the word document,
#then close word manually.
$oWord->Quit();
print "Finished.{$sNL}";
?>
