I do have code assist, but for some reason all I got was a compile error, not a hint on how to disable "possible exceptions". I must admit I'm not using the standard Eclipse, but an Eclipse version which is tailored for the Sonic ESB, so maybe there's something in there which prevents it. And the tips are appreciated, as always. A good programmer is someone who always looks both ways before crossing a one-way street. (Doug Linder)

I do recall, when I downloaded and installed VS2008C# Express, I was asked whether I also wanted (1) SQL Server Express and (2) SilverLight. I don't recall the details for VS2008 WebDev Express. :) Luc Pattyn [Forum Guidelines] [My Articles] Nil Volentibus Arduum Please use <PRE> tags for code snippets, they preserve indentation, improve readability, and make me actually look at the code.

Thanx for the tip, will try it out soonish as my harddrive died on me today X| A good programmer is someone who always looks both ways before crossing a one-way street. (Doug Linder)

I've put up a demo project with my implementation here: Clicky![^] Hope it helps. A good programmer is someone who always looks both ways before crossing a one-way street. (Doug Linder)

No problem :) The need to optimize rises from a bad design.My articles[^]

Thanks for the tip. I'll take a look at it. A good programmer is someone who always looks both ways before crossing a one-way street. (Doug Linder)

Thanks for the suggestion, but I was looking for a method of accomplishing this without the overwrite of AssemblyInfo.cs. The consumer isn't a moron; she is your wife.

Try Red Gate's Memory Profiler[^]. HTH Jinal Desai - LIVE Experience is mother of sage....

This would appear to be either a VB.NET or COM question, I see nothing about C# here. Try posting in the correct forum. It's time for a new signature.

have you tried removing Internal keyword? Or tried add public in front of class? Is this class a DLL? Helfdane wrote: Thing is, I can load this class, but I cannot call the methods on it When you set your debugger, in Quick watch can you use method or what kind of error will throw?

The exception is thrown on the line: "formula = (CompiledFormula)formatter.Deserialize(stream);" This is the only deserializationcode I have, since I let the framework handle it. I'm suspecting the name '9-onzk69' is the name of the temporary file created by the codeprovider which compiles it, but I don't know for sure, as a system wide file search comes up empty. The stack trace of the exception is: at System.Runtime.Serialization.Formatters.Binary.BinaryAssemblyInfo.GetAssembly() at System.Runtime.Serialization.Formatters.Binary.ObjectReader.GetType(BinaryAssemblyInfo assemblyInfo, String name) at System.Runtime.Serialization.Formatters.Binary.ObjectMap..ctor(String objectName, String[] memberNames, BinaryTypeEnum[] binaryTypeEnumA, Object[] typeInformationA, Int32[] memberAssemIds, ObjectReader objectReader, Int32 objectId, BinaryAssemblyInfo assemblyInfo, SizedArray assemIdToAssemblyTable) at System.Runtime.Serialization.Formatters.Binary.__BinaryParser.ReadObjectWithMapTyped(BinaryObjectWithMapTyped record) at System.Runtime.Serialization.Formatters.Binary.__BinaryParser.ReadObjectWithMapTyped(BinaryHeaderEnum binaryHeaderEnum) at System.Runtime.Serialization.Formatters.Binary.__BinaryParser.Run() at System.Runtime.Serialization.Formatters.Binary.ObjectReader.Deserialize(HeaderHandler handler, __BinaryParser serParser, Boolean fCheck, Boolean isCrossAppDomain, IMethodCallMessage methodCallMessage) at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize(Stream serializationStream, HeaderHandler handler, Boolean fCheck, Boolean isCrossAppDomain, IMethodCallMessage methodCallMessage) at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize(Stream serializationStream) at Compiler.CompilerSingleton.LoadFormuleFromAssembly(Byte[] array) The InnerException is null.

Or both? :-D

The assembly created, as it is now, is a 1 function class which on disk is no more than a 10k .cs file. The dynamic part is the function body which is generated. For me, I think the problem can either be in the byte array generation (the point of your suspicion), or at the load routines. I'm still considering namespaces to be an issue too, but haven't gotten any proof of me being right or wrong. The hunt continues... The consumer isn't a moron; she is your wife.

You could try looking at this[^] article, to see if it gets you at least started. I found this by googling 'propertybag'. You could try that, if the article above doesn't help you. It just seemed closest of the first page to your question. Good luck! :) Henry Minute Do not read medical books!

You have valid points, thanks for your input. We are talking a multi-user environment, that is, multiple users can do a request for a number of calculations (there is one dispatcher which processes the requests by transforming it into the format used by the calculation engine. This dispatcher will probably have a WCF component for the thin clients to talk to, this is not final yet. In addition, the dispatcher will have the possibility of throttling the requests if the queue becomes too big, but that is something I haven't worked out yet; it's still on the drawing board). The dispatcher is designed to also monitor the system resources, as on which it will base his throttling and batching strategy. This should lessen the preassure on the hardware as well. The test-case I had was 15k calculations (1000 base calculations with 15 subcalculations each in testing data). This means that when the calculation starts, 15k calculations are in the queue. The thing which hints me that nothing is happening is, that when queuing the first action of a calculation, the calculation routine is sending a notification to the console that it is starting, but the starting message never gets there unless queuing is done and so is the load. I am not sure if my current infrastructure will be sufficient, hence my research and these forum postings, as I am not sure if I want to use a component (the threadpool in this case) where I cannot predict exactly what will happen. I think I do need threading since missing parts required for a calculation need to be fetched from the DB and/or are dependant on other calculations. My background is saas with an average load of 500+ simultanious connections for clients who operate globally. My background is not primarily with .net. The consumer isn't a moron; she is your wife.
