One thing to watch out for with using COM objects is to make sure you actually close the application when you're done using it and/or don't end up opening multiple instances of the application. I can't remember what the exactly sequence was, but I think it was either Application.Exit() or Application.Quit() (or both?). I think the Application.Close() method just closes the document and not the application and.. again going on memory here... I believe the default state of the application was Visible = False, so you wouldn't even see that the application is still running unless you pulled up the Task Manager. I don't know anything about memory leaks with this process, just know that this is one big "gotcha" that can eat up a ton of CPU and memory resources. For me, COM is a last resort. It's bulky and ugly and has a lot of potential for things like memory leaks and system instability in general. You might look to see if there's a PEAR package that can do what you want to do without using Word directly. -TG ----- Original Message ----- From: Gustav Wiberg <gustav@xxxxxx> To: 'PHP-Windows Group' <php-windows@xxxxxxxxxxxxx> Date: Wed, 10 Oct 2007 09:36:00 +0200 Subject: PHP-memory leak with COM-objects? > Hi! > > I want to use COM+ objects (especially with Word).
