  • Can I use Google's Protocol buffers for processing LDAP requests in my LDAP server?

    - by Naga
    Hi, I need to process the incoming predefined ASN format data(coming from verity of clients that uses BER library to build it) in my application server. This is typically an LDAP server where every request will be in a predefined ASN format. Can i use Google's protocol buffers to process the requests in the server side? Will it help any way to improve performance of my servers request handling? Is it anyway reduce the number of malloc() calls that happens while processing ASN messages? Thanks, Naga

  • How to inherit from DataAnnotations.ValidationAttribute (it appears SecureCritical under Visual Stud

    - by codetuner
    Hi, I have an [AllowPartiallyTrustedCallers] class library containing subtypes of the System.DataAnnotations.ValidationAttribute. The library is used on contract types of WCF services. In .NET 2/3.5, this worked fine. Since .NET 4.0 however, running a client of the service in the Visual Studio debugger results in the exception "Inheritance security rules violated by type: '(my subtype of ValidationAttribute)'. Derived types must either match the security accessibility of the base type or be less accessible." (System.TypeLoadException) The error appears to occure only when all of the following conditions are met: a subclass of ValidationAttribute is in an AllowPartiallyTrustedCallers assembly reflection is used to check for the attribute the Visual Studio hosting process is enabled (checkbox on Project properties, Debug tab) So basically, in Visual Studio.NET 2010: create a new Console project, add a reference to "System.ComponentModel.DataAnnotations" 4.0.0.0, write the following code: . using System; [assembly: System.Security.AllowPartiallyTrustedCallers()] namespace TestingVaidationAttributeSecurity { public class MyValidationAttribute : System.ComponentModel.DataAnnotations.ValidationAttribute { } [MyValidation] public class FooBar { } class Program { static void Main(string[] args) { Console.WriteLine("ValidationAttribute IsCritical: {0}", typeof(System.ComponentModel.DataAnnotations.ValidationAttribute).IsSecurityCritical); FooBar fb = new FooBar(); fb.GetType().GetCustomAttributes(true); Console.WriteLine("Press enter to end."); Console.ReadLine(); } } } Press F5 and you get the exception ! Press Ctrl-F5 (start without debugging), and it all works fine without exception... The strange thing is that the ValidationAttribute will or will not be securitycritical depending on the way you run the program (F5 or Ctrl+F5). As illustrated by the Console.WriteLine in the above code. But then again, this appear to happen with other attributes (and types?) too. Now the questions... Why do I have this behaviour when inheriting from ValidationAttribute, but not when inheriting from System.Attribute ? (Using Reflector I don't find special settings on the ValidationAttribute class or it's assembly) And what can I do to solve this ? How can I keep MyValidationAttribute inheriting from ValidationAttribute in an AllowPartiallyTrustedCallers assembly without marking it SecurityCritical, still using the new .NET 4 level 2 security model and still have it work using the VS.NET debug host (or other hosts) ?? Thanks a lot! Rudi

I'm trying to get frame by using arVideoGetImage() function in order to process for with openCV functions. however program throws a "System.AccessViolationException" error in the following line of face detection example: CvSeq *faces = cvHaarDetectObjects(img, cascade, storage, 1.1, 3, 0, cvSize( 40, 40 )); ARtoolkit and openCV are work perfectly separately. Anyone has able to work these two library together, or any suggestion?? thanks

  • How to dismiss keyboard for UITextView with return key?

    - by iPhoney
    In IB's library, the introduction tells us that when the return key is pressed, the keyboard for UITextView will disappear. But actually the return key can only act as '\n'. I can add a button and use [txtView resignFirstResponder] to hide the keyboard. But is there a way to add the action for the return key in keyboard so that I needn't add another button.

  • Jruby Gems-in-a-jar issue

    - by antonio
    Hi all, I am trying to write some code in ruby (using jruby) to be compiled to java bytecode with jrubyc and deployed to a remote machine where it will be run on the JVM (no ruby available there). Everything works fine as long as I am happy to stick with the standard jruby library. As explained on the jruby website, I simply copy the jruby-complete.jar library to the remote machine and include it in the classpath at runtime. I fire my compiled script and it works: cool! The problems start when I need some other libraries (typically rubygems) to run my script. I am aware of cool stuff like rawr, -which I successfully tested- to put together all you need in a single package. However that is not the solution I am looking for: I will have many small scripts to run independently and I don't want each of them to grow to at least 10 MB just because I insanely include the jruby-complete.jar in each of them. What I would like is to compile a .jar for each of the libraries that I will need to use, put all of them in a common folder on the remote machine and include them at runtime in the classpath when I run my compiled jruby scripts on the JVM. This said, I tried to follow the instructions here: http://blog.nicksieger.com/articles/2009/01/10/jruby-1-1-6-gems-in-a-jar I tried exactly the example shown there, with the "chronic" gem. Going step by step: Install the gem locally: java -jar jruby-complete-1.1.6.jar -S gem install -i ./chronic chronic --no-rdoc --no-ri Package it into a jar: jar cf chronic.jar -C chronic . Write a two lines test script, saving it as testt.rb: require 'chronic' Chronic.parse('tomorrow') Compile with: jrubyc testt.rb Run the resulting java class testt.class with the following (having both jruby-complete.jar and chronic.jar in the same folder as the java class): java -cp .:/jruby-complete.jar:./chronic.jar testt I get the following error: Exception in thread "main" file:/Users/ave2/NetBeansProjects/jrubywatir/lib/jruby-complete.jar!/METAINF/jruby.home/lib/ruby/site_ruby/shared/builtin/core_ext/symbol.rb:1:in `const_missing': uninitialized constant Chronic (NameError) from testt.rb:2 ...internal jruby stack elided... from Module.const_missing(testt.rb:2) from (unknown).(unknown)(:1) I really don't understand what I am doing wrong, and I am totally stuck on this. I am a noob in Ruby, much more used to Python: don't miss a chance to convert an infidel! :-) Thanks.

  • UITextView w/ Syntax Highlighting

    - by Travis
    Is there a common library, parser, etc. for Cocoa or Cocoa-Touch that can take a chunk of text and do the proper syntax highlighting? As a simple example, I'd like to have a UITextView that has C/C++ syntax highlighting.

  • Can someone provide an example of seeking, reading, and writing a >4GB file using boost iostreams

    - by Queueless
    I have read that boost iostreams supposedly supports 64 bit access to large files semi-portable way. Their FAQ mentions 64 bit offset functions, but there is no examples on how to use them. Has anyone used this library for handling large files? A simple example of opening two files, seeking to their middles, and copying one to the other would be very helpful. Thanks.

  • Exactly what is a "third party"? (And who are the first and second party?)

    - by aioobe
    I know precisely what a "third-party library" is, so I assume that the "third-party" in this case, simply is an arbitrary person/company other than the developer? Has it to do with "first person" / "second person" etc perhaps? The fact that there is a "third party" suggests that there is a "first party" and a "second party" as well. Are those terms well defined? (I'm not a native english speaker.)

  • Business Intelligence Development Studio encounter error on Rendering

    - by user366796
    I try to develop a data processing extension for SSRS 2008 in order to access database through an entity framework. But when I copy and register the extension in BI Development Studio, it gives me an error message while loading the extension". I built it with targeting framework 4.0 by using Visual Studio 2010 because my data model class library was built with that version of target framework. Any help will be greatly appreciated. Thanks.

  • Breaking a concave polygon into convex ones.

    - by Bart van Heukelom
    I'm using a game physics library (Box2D) which only supports convex polygon shapes. However, I'd like the level builder to be able to just specify concave polygons without having to worry about that. So, how can I automatically break apart a concave polygon into convex ones (or even all triangles). Speed would be cool, but ease of implementation is more important. The breaking apart will only be done on game initialization. (My language is Flash/ActionScript 3, but that shouldn't matter)

  • Share functions between Crystal Reports without Crystal Reports Server?

    - by Aidan Ryan
    We have several reports that do the same formatting operations (e.g. displaying "PASS" or "FAIL" if a value is within a particular range.) Without Crystal Reports Server, is there a way to share functions between reports so that they do not need to be duplicated? I understand I could do this with a user function library but I would prefer not to port all of the crystal functions to UFL. Using Crystal Reports 2008.

  • NetBeans not liking libraries in lib-src

    - by DJTripleThreat
    I'm working on a project with a group that is using Eclipse, but I'm using Netbeans. Up until today this wasn't an issue. When updating from the repo they have added some source code as a library under a directory called /lib-src. When I try to compile the code I get an error that it can't find certain packages... these are the packages under /lib-src. Using NetBeans I can add the library as a folder so now the references to those packages are happy. However, I'm getting this new error when compiling: UNEXPECTED TOP-LEVEL ERROR: java.lang.OutOfMemoryError: Java heap space at java.util.HashMap.addEntry(HashMap.java:753) at java.util.HashMap.put(HashMap.java:385) at com.android.dx.dex.file.ClassDataItem.addStaticField(ClassDataItem.java:134) at com.android.dx.dex.file.ClassDefItem.addStaticField(ClassDefItem.java:280) at com.android.dx.dex.cf.CfTranslator.processFields(CfTranslator.java:159) at com.android.dx.dex.cf.CfTranslator.translate0(CfTranslator.java:130) at com.android.dx.dex.cf.CfTranslator.translate(CfTranslator.java:85) at com.android.dx.command.dexer.Main.processClass(Main.java:297) at com.android.dx.command.dexer.Main.processFileBytes(Main.java:276) at com.android.dx.command.dexer.Main.access$100(Main.java:56) at com.android.dx.command.dexer.Main$1.processFileBytes(Main.java:228) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:134) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.processDirectory(ClassPathOpener.java:190) at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:122) at com.android.dx.cf.direct.ClassPathOpener.process(ClassPathOpener.java:108) at com.android.dx.command.dexer.Main.processOne(Main.java:245) at com.android.dx.command.dexer.Main.processAllFiles(Main.java:183) at com.android.dx.command.dexer.Main.run(Main.java:139) at com.android.dx.command.dexer.Main.main(Main.java:120) at com.android.dx.command.Main.main(Main.java:87) /home/aaron/NetBeansProjects/xbmc-remote/nbproject/build-impl.xml:411: exec returned: 3 BUILD FAILED (total time: 1 minute 25 seconds) I can include the build-impl.xml file if you need it, but I don't think that is main issue.

  • Ruby1.9 and Amazon SQS?

    - by fields
    Is there a good library/gem for accessing Amazon SQS from ruby1.9? The Amazon ruby example and right_aws do not work as-is with ruby1.9. I'd strongly prefer something that's known to work under reasonably heavy load (a few hundred thousand queue items or more per day).

  • IronPython and Nodebox in C#

    - by proxylittle
    My plan: I'm trying to setup my C# project to communicate with Nodebox to call a certain function which populates a graph and draws it in a new window. Current situation: [fixed... see Update2] I have already included all python-modules needed, but im still getting a Library 'GL' not found it seems that the pyglet module needs a reference to GL/gl.h, but can't find it due to IronPython behaviour. Requirement: The project needs to stay as small as possible without installing new packages. Thats why i have copied all my modules into the project-folder and would like to keep it that or a similar way. My question: Is there a certain workaround for my problem or a fix for the library-folder missmatch. Have read some articles about Tao-Opengl and OpenTK but can't find a good solution. Update1: Updated my sourcecode with a small pyglet window-rendering example. Problem is in pyglet and referenced c-Objects. How do i include them in my c# project to be called? No idea so far... experimenting alittle now. Keeping you updated. SampleCode C#: ScriptRuntimeSetup setup = Python.CreateRuntimeSetup(null); ScriptRuntime runtime = new ScriptRuntime(setup); ScriptEngine engine = Python.GetEngine(runtime); ScriptSource source = engine.CreateScriptSourceFromFile("test.py"); ScriptScope scope = engine.CreateScope(); source.Execute(scope); SampleCode Python (test.py): from nodebox.graphics import * from nodebox.graphics.physics import Vector, Boid, Flock, Obstacle flock = Flock(50, x=-50, y=-50, width=700, height=400) flock.sight(80) def draw(canvas): canvas.clear() flock.update(separation=0.4, cohesion=0.6, alignment=0.1, teleport=True) for boid in flock: push() translate(boid.x, boid.y) scale(0.5 + boid.depth) rotate(boid.heading) arrow(0, 0, 15) pop() canvas.size = 600, 300 def main(canvas): canvas.run(draw) Update2: Line 139 [pyglet/lib.py] sys.platform is not win32... there was the error. Fixed it by just using the line: from pyglet.gl.lib_wgl import link_GL, link_GLU, link_WGL Now the following Error: 'module' object has no attribute '_getframe' Kind of a pain to fix it. Updating with results... Update3: Fixed by adding following line right after first line in C#-Code: setup.Options["Frames"] = true; Current Problem: No module named unicodedata, but in Python26/DLLs is only a *.pyd file`. So.. how do i implement it now?!
