• Building a DLL via Maven with mojo-native

  - by graham.reeds

  I can build a simple dll consisting of a source file, a header file and a definition but now I am progressing beyond a simple toy dll and working towards something more real (ie: more complex). The DLL I am trying to compile has 2 source files, 2 headers and the dreaded stdafx pair. To compile normally you would use /Yc for the pch and /Yu to use it. How do you specify that with in the constraints of mojo-native's compiler options?

• Where can I find a good collection of public domain owl ontologies for various domains?

  - by Kevin Pauli

  I am building an ontology-processing tool and need lots of examples of various owl ontologies, as people are building and using them in the real world. I'm not talking about foundational ontologies such as Cyc, I'm talking about smaller, domain-specific ones.

• Scala: custom control structures with several code blocks

  - by Vilius Normantas

  Is it possible to create a custom control structure with several code blocks, in the fashion of before { block1 } then { block2 } finally { block3 }? The question is about the sugar part only - I know the functionality can be easily achieved by passing the three blocks to a method, like doInSequence(block1, block2, block3). A real life example. For my testing utilities I'd like to create a structure like this: getTime(1000) { // Stuff I want to repeat 1000 times. } after { (n, t) => println("Average time: " + t / n) }

• Are there any 3rd Party libraries for image processing in C#?

  - by Gaax

  Just wondering if there's anything out there to help make my project a lot easier to deal with. I'm working on a program that uses the Wiimote and infrared pen (mapped to the mouse) to manipulate images in real time and I'd much rather not have to use all my time figuring out how to make the program resize and rotate images efficiently with the least amount of distortion... I haven't really found anything when searching. Anybody know of any libraries that can help me?

• regular expression

  - by Jeeenda

  Hi I need a regular expression that'll give me something like this part ./something\", [something.sh from something like this string ("./something\", [something.sh", ["./something\", [something.sh"], [/* 37 vars */]) is that possible? I'm having real trouble making this since there's that \" escape sequence and also that ',' character, so I cannot simply use match everything instead of these characters. I'm working on unix so it's also possible to use pipeline of few greps or something like that. Thanks for advice.

• I want to scramble an array in PHP

  I want PHP to randomly create a multi-dimensional array by picking a vast amount of items out of predefined lists for n times, but never with 2 times the same. Let me put that to human words in a real-life example: i want to write a list of vegetables and meat and i want php to make a menu for me, with every day something else then yesterday. I tried and all i got was the scrambling but there were always doubles :s

• Stack Trace of cross-thread exceptions with Invoke

  - by the_lotus

  When an exception happens after calling Invoke, .NET shows the stack trace as if the error happens while calling Invoke. Example below: .NET will say the error happen in UpdateStuff instead of UpdateStuff - BadFunction Is there a way to catch the "real" exception and show the correct stack trace? Private Sub UpdateStuff() If (Me.InvokeRequired) Then Me.Invoke(New UpdateStuffDelegate(AddressOf UpdateStuff)) Return End If Badfunction() End Sub Private Sub BadFunction() Dim o As Object o.ToString() End Sub

• How to share memory buffer across sessions in Django?

  - by afriza

  I want to have one party (or more) sends a stream of data via HTTP request(s). Other parties will be able to receive the same stream of data in almost real-time. The data stream should be accessible across sessions (according to access control list). How can I do this in Django? If possible I would like to avoid database access and use in memory buffer (along with some synchronization mechanism)

• Delphi low-level machine parameter access

  - by tonyhooley.mp

  There are many very low-level parameters measured by PCs and their processors (e.g. core temperatures, fan-speeds, voltage levels at various parts of the motherboard and processor internals) which are available and displayed by the BIOS, and by some aaplication programs. How does one access these low-level (real-time) data via Delphi? Is there a library? Is there a Windows API?

• What's a good pure-python, document-based and flat-file database engine?

  - by joe Simpson

  Hi, for development i'd love to have a flat file database with the requirements up in the title, but I don't seem to be able to find a database with these requirements. I can't seem to get MetaKit to work. I only need it to work on the development machine, but in the real world my product will have more data and needs more room and will need something better. Does anyone know of a database engine capable of this or do I need to just use python's pickle and load and save a file? Joe

• What are the differences and similarities between the .NET languages?

  - by froadie

  I'm trying to figure out how much overlap there is between the different languages of the .NET framework, and what the real differences are. Is there an overlap of libraries/methods/functions...? If I'm googling a question for, say, VB .NET, and C# answers come up, what can I take from the C#-relevant info and what differences/incompatibilities should I look out for?

• How to line-wrap console output in NetBeans 6.8?

  - by JRL

  Is there a way to make the console output text wrap based on the actual width of the window? I have limited screen height real estate on my laptop, and so want to have the console window docked on the right rather than the bottom of the window. An option or a plugin is fine, I'm using NetBeans 6.8. If this exists in a newer version of NetBeans, please say so, but I can't install a dev build.

• SQL Server 2005 Error "The user does not have permission to perform this action" - clears up after r

  - by Sylvia

  We're getting the error "The user does not have permission to perform this action" during times of heavy load (regularly, when a trim job occurs). The error clears up when the service accessing sql server is restarted, so it's obviously not a real permissions problems. There's a possibility that the problem is occurring when we're trying to query dm_tran_active_transactions and sys.dm_tran_session_transactions. Any ideas of good places to start looking? thanks for any insights...

• How can I use wildcard urls with Code Igniter?

  - by tarnfeld

  I am building a system that has urls like app.com/login and app.com/dothing but it will also have app.com/xOldP. The web application is build using the latest version of Code Igniter and I was wondering if there was a way to add a check in, that if the url is a controller then do that and finish, but if not, do something else (which will check the url and if its not real 404, which I can do). I was wondering how annoying this would be :/ Some sample code or links would be great!
