Hi Oleg, Thanks for the suggestion.
Been sick with a nasty throat infection which put me to bed for 3 days. Still, I was able to compile and debug the JFE example and what it does is call J.DLL directly. I still haven't gotten around to integrating it. It is most likely that I'll implement this solution instead of using COM. My only concern is that I was hoping to use the interactive J session to analyze the data coming in from the game engine. Also, since it is using J.DLL, I would not be able to access some "windows/forms" capabilities but I'll just cross the bridge when I get there.

Note in header: /* File created by MIDL compiler version 5.01.0164 */ It means that these thunks should be able to be regenerated just from the DLL directly again, ie imported as references, whatever it is now called. However, maybe using it as DLL is better and more portable than using COM. See the ~system/examples/jfe folder. Also think and compare how it works with C#. > From: Alex Rufon <[EMAIL PROTECTED]> > > Hi. > > > > A few years back, I was able to integrated J5 with the Torque Game > Engine .
