RE: [PHP-WIN] RE: PHP4 & GIF Generation, I'm stuck!

I don't know if this helps you, it is a paragraph taken from "Developing ASP Components" (O'Reilly): "When a client wants to create an instance of a component and query for an interface on that component, it must do two things. first, it must initialise COM - call itwaking COM up - by calling a function named CoInitialize or CoInitializeEx. CoInitialize takes one parameter, a value of NULL, and CoInitializeEx takes two parameters, the first again being NULL and the second containing a flag describing the thread's concurrency model. Either of these functions is only called once on a thread and basically initializes the COM library on that thread." So, it would appear that your COM object is trying to re-initialize COM. This in PHP3/CGI is no problem because the thread dies as soon as the script finishes, however with ISAPI PHP4, the thread is still around to process requests and already had the COM library initialised. This is where my knowledge becomes supposition :-) *If* this is the case, you may be able to use CoInitialiseEx with an apartment or both threaded model - this may then execute it in the same style as an ASP component which tries for both-threaded, then settles for apartment-threaded if it has to. Or, alternatively, run PHP4 as CGI...

Mark, 0. otf_GIF works with ASP and PHP3 and CGI applications without difficulty. They continue to work after the PHP4 failure. 1. unset($id) had no effect. 2. Cannot test MSword example, Office not installed on server. Other objects have same result. 3. PHP seems to clean up well. Cannot find evidence of dll in memory after execution. 4. We are C challenged here. Although not elegant, a command line version could be built. It is a good idea for fallback, thanks. 5. Multiple simultaneous executions are permitted (refer to 0 above).

Php-windows is probably the right place for anybody who cares about PHP + COM. I've never used com in PHP but it looks like the connection has been initialised but never killed. Is there any sort of unload function for com or your ActiveX control? Try unset($id) and see if that works. Can you use other com objects repeatedly? Like the MS Word example? Can other tools the otf_GIF com object repeatedly? Is there away of tracing what OCX's are being used in memory? I seem to remember some tool that came with VB years ago that allowed you to kill specific .dll's in memory and maybe .vbx's but hey i know nothing about any of this, and im just guessing. Since you are from dkt.com i assume you are somehow involved in writing otf_GIF why not just build a C app to do it on the command line? Deploy your site with the command line option then go back to working on this problem. Something like "CoInitialize has not been called" sounds like you need to expressly state that more than one of these things can be in use at a time... (Even if you did unset() it i would be concerned about simultaineous users) Just some guesses, mn -----Original Message----- From: Howard Cohodas [mailto:Howard.Cohodas@dkt.com] Sent: Tuesday, July 11, 2000 7:03 AM To: Website-Talk; Php-Windows; Php-General; Php-Dev Subject: PHP4 & GIF Generation, I'm stuck! I'm out of things to try so I hope one of you has an idea. The only item holding us back from deploying a php4 site we are working on is that we are unable to get the Windows COM interface working.
