Hi Matthew, 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. I'll be back in the office tomorrow though and will give your problem a run through.
The only caveat is that my dev machine is WindowsXP Pro 32bit so I may not hit your problem since when I read your earlier code ... the only reason it would have failed is if J.DLL wasn't registered properly which you have done so correctly. Although I have been to some dev discussions at the office where they mentioned the an Interopt problem when there was a deployment to a 64bit machine, I'll guess I'll have to ask them how they worked around it. 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. Hmmm. I hope I don't offend you but are you using the 64bit version of J? r/Alex ________________________________________ From: [email protected] [[email protected]] On Behalf Of Matthew Brand [[email protected]] Sent: Wednesday, December 16, 2009 12:19 AM To: Programming forum Subject: Re: [Jprogramming] C# .NET COM JDLLServer I have done some investigations (outside of NinjaTrader, just using Visual Studio c#). I do not know for sure, but it might be that the JDLLServerClass does not work on 64 bit Windows 7? I am in way over my head here, I have no idea what is going on - so apologies in advance if I am wrong. I read this: http://blogs.msdn.com/mshneer/archive/2009/12/07/interop-type-xxx-cannot-be-embedded-use-the-applicable-interface-instead.aspx So I removed the "Class" prefix from "JDLLServerClass" to end up with a program that looks like this: using System; using System.Collections.Generic; using System.Linq; using System.Text; using JDLLServerLib; using JEXEServerLib; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { // JDLLServerClass j = new JDLLServerClass(); JDLLServer j = new JDLLServer(); object result; int status = j.DoR("2| !/~i.4", out result); string.Format("J DoR ended with status {0} and result\n{1}", status, result); } } } But now I get a different error: System.Runtime.InteropServices.COMException was unhandled Message=Retrieving the COM class factory for component with CLSID {21EB05EA-1AB3-11CF-A2AC-8FF70874C460} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

WORKAROUND: The possible workaround is modify your project's platform from 'Any CPU' to 'X86' (in Project's Properties, Build/Platform's Target) ROOTCAUSE The VSS Interop is a managed assembly using 32-bit Framework and the dll contains a 32-bit COM object. If you run this COM dll in 64 bit environment, you will get the error message.
