OK, so I tried with Corman Lisp 3.0 (using CREATE-THREAD) - no problems, no locking, like with LispWorks. Maybe someone on this list can try the same with ECL, so we've covered all Lisps on Windows with MP capabilities. > I got a response from Charley Cox that suggests another route is > needed around this, or I guess I will just have to consider changing > my model of how to program. Yeah, or you change your Lisp implementation... :)

Again, I don't think this is a problem of RDNZL but rather of how the various Lisp implementations handle callbacks into Lisp. The following code works fine (output as expected, no IDE locking) for me with LispWorks 5.0 and AllegroCL 8.0 (using SLIME) - it crashes with Corman Lisp 3.0, though. Cheers, Edi.

As there is no assembly with that name, the failure is what has to be expected. > But that does not work. Instead you have to do this > > (import-type "System.Threading.Thread") > (import-type "System.Threading.ThreadStart") Yep, that's the correct way to do it.

I think that's a problem related to the IDE and not to RDNZL. In LispWorks 5.0, for example, if I start the apropos example coming with RDNZL (which also uses Application.Run) with MP:PROCESS-RUN-FUNCTION as suggested in the RDNZL documentation it runs fine without locking the IDE, i.e. I can still use the listener or other graphical tools while the .NET window is up and interacting. > How can I do this in rdnzl? Can I mix CG and rdnzl? I don't know much about CG but I think that will be very hard or impossible. But that's not a problem of Lisp/RDNZL. I think it would be equally hard to mix a C++ program using MFC with a C# program using .NET's windows forms.

Lucky you! :-) Actually, the RDNZL.dll included in the binary package is the one compiled with VS2005, not the one provided in RDNZL package. Can you retry by using your RDNZL.dll instead? Michael.

Thanks for the info. If you find out that there's a specific problem with ACL7, let me know, and I'll try to fix it.

Yes, but I can't be sure this didn't happen with earlier versions. Also there have been recent changes in ECL to implement finalizers, which I'm trying to use in the ECL-port of RDNZL. Michael.

I've released new versions of the Lisp and the C++ code which implement this - just in case. Thanks for the suggestion.

There are so many different parameters, it's difficult to tell. Can you trace whether your .NET objects referenced in LISP get collected or not? In the case of the apropos example, it appears that the KeyPressEventHandler object never got collected in the LISP world. Michael.
