Hi Matthew, I asked the team leader for the project I mentioned and they actually solved it two ways: 1. As suggested, compiled the solution with platform set to x86 instead of AllCPU. 2. Went back to some of the 3rd party suppliers and got versions for the 64bit OS. Actually, with this, they eliminated the use of Interopt's.
I'm a bit embarrassed that my reply is not very useful to your problem. r/Alex -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Matthew Brand Sent: Wednesday, December 16, 2009 4:45 PM To: Programming forum Subject: Re: [Jprogramming] C# .NET COM JDLLServer Hi Alex, > Just saw this thread (and the previous ones) ... unfortunately I'm at home > right now and the machine here is configured for gaming so theres no > development tools whatsoever installed.

Thanks, much appreciated ... I am stumped. :-). > > I know its a long shot but can you give JEXEServer a try instead of JDLL? I > believe it would still throw the same error though but its a curiosity. Your EXE suggestion worked. In Visual Studio using EXE server works, but using DLL does not. So I thought my problem was solved, but alas... The NinjaTrader C# IDE does not seem to allow references to EXE, only to DLL! I will ask them about it on their forum. I will try to make visual studio project to output a DLL containing a pass-through to the J EXE, which hopefully I can call from NinjaTrader. > > Hmmm. I hope I don't offend you but are you using the 64bit version of J? No offense taken, please feel free to suggest even the most basic things. I know absolutely nothing about DLL's - apart from it appears to be an incredibily complicated and delicate affair. I appreciate any advice given.
