Hi again!
I want the logged-in user to able to open a word-file (or an Excel-file or
whatever) and then Push Save-Icon and make sure that changes are actually
made.
Example:
John opens up file c:\test.doc. He writes "Ugly cow" in it and pushes the
save-icon. Ugly Cow is now stored in file c:\test.doc. Working with
COM-objects is the only solution I have found!?
Normally If John opens up c:\test.doc Internet Explorer (or whatever
browser) saves the file temporarily in some temp-folder (don't know exact
location), lets say c:\temp\sdifiuweoriu2734872.tmp. When John pushes
Save-icon he saves the new information TO the temporarily stored file IF he
doesn't use Save AS...
Please come with suggestions :-)
Best regards
/Gustav Wiberg

Subject: Re: PHP-memory leak with COM-objects?
I've worked a lot with the Word COM and while it works well on a
single desktop, I wouldn't recommend it for a server process. It's
rather slow and while the memory eventually gets cleaned up, it still
takes up a lot of memory for as little as it does. I'm not so sure
OpenOffice is much better in this regard.
You could push these tasks to another server, but I'd also look at
what you are doing and see if you can do it another way. We currently
use Word documents as template for a mail merge type operation and are
looking to move these to RTF since that enables us to take Word out of
the loop when doing the mail merge ( we actually just do a global find
and replace in the document since we've found more consistent results
with that ). But again, this all depends upon the application.

Hi!
I want to use COM+ objects (especially with Word). I have understood (a
lot of reading on the Internet) that when initiating COM-objects with
Word (even if the object is released in variable in the code). Word leaks
a lot of memory. I have also read that if I want to use Word-COM+ object
I should have a dedicated server because it takes so much memory.
I have tested some and I easily get out of memory even if there is 4GB on
the server I tested against.
Then I run PHP as ISAPI, and the suggestion on the php.net site was to
run PHP as CGI because COM-objects are run in the same memory-space as
ISAPI when running as ISAPI-module.

What do you guys thinks about above? Give me some feedback, please :-)
