• grails metaprogramming

  - by Don

  Hi, My understanding is that there are two obvious places in a Grails app where one can do meta-programming: The init closure of Bootstrap.groovy The doWithDynamicMethods closure of a plugin The meta-programming I'm referring to here should be visible throughout the metaprogramming, typical examples include adding (or replacing) methods of 3rd party classes. String.metaClass.myCustomMethod = { /* implementation omitted */ } The disadvantage of (1), is that the metaprogramming won't be applied when the application is dynamically reloaded. The disadvantage of (2) is that I need to create and maintain an entire plugin just for the sake of a little metaprogramming. Is there a better place to do this kind of metaprogramming? Thanks, Don

• Trouble with using ActiveX control in .net windows application

  - by alex dee

  C#, visual studio 2005 I have several 3rd party activeX control. I need to use them in my .net windows application. These controls are graphical. I created a wrapper with aximp.exe for them. But it seems that something wrong. When I call some methods of wrapped activeX control == targetinvocativeexception occured. Or visual studio writes "you are attempting to write or read protected memory". I know that something wrong. But what is exactly wrong - i don't know. I find out about method CreateControl() or STAthread attribute. but it doesn't help me. What is the common problem and common solution for my type of problem ? These activex control from big and trusted company, other developers work with them.

• Temp file that exists only in RAM?

  - by Auraomega

  I'm trying to write an encrpytion using the OTP method. In keeping with the security theories I need the plain text documents to be stored only in memory and never ever written to a physical drive. The tmpnam command appears to be what I need, but from what I can see it saves the file on the disk and not the RAM. Using C++ is there any (platform independent) method that allows a file to exist only in RAM? I would like to avoid using a RAM disk method if possible. Thanks Edit: Thanks, its more just a learning thing for me, I'm new to encryption and just working through different methods, I don't actually plan on using many of them (esspecially OTP due to doubling the original file size because of the "pad"). If I'm totally honest, I'm a Linux user so ditching Windows wouldn't be too bad, I'm looking into using RAM disks for now as FUSE seems a bit overkill for a "learning" thing.

• Efficiently making web pages from multiple servers

  - by james.bcn

  I want to create a service that allows diverse web site owners to integrate material from my web servers into content served from their own servers. Ideally the resulting web page would only be delivered from the web site owners server, and the included content would be viewed as being part of the site by Google - which I think would rule out iframes or client-side Javascript to get the content from my server (although I may be wrong about that?). Also the data wouldn't actually be updated that often, say once a day, so it would be inefficient to get the data from my web servers with every request. Finally, the method needs to be as simple as possible so that it is easy for web site owners to integrate into their own sites. Are there any good methods for doing this sort of thing? If not then I guess the simple way is with iframes or Javascript.

• A way to avoid deriving from the provider classes in mvc authentication

  - by Shymep

  Looking for the best practice for authentication in MVC I unfortunately didn't find the clear answer to my question. Thinking of the problem I tried to imagine some priciples that could be useful in my design. Well, I would like to use a base AccountController class I want to place all the tables such as "Users", Roles, Rights etc into my own database. But I wouldn't like to implement the standard aspnetdb design (which can be easy got by using aspnet_regsql) So the main question is can I do this without deriving abstract classes like MembershipProvider, RoleProvider etc? What I would prefer not to do is implement all the abstract methods from these classes. The second question is still about the best practice for authentication e.g. for the small projects, for the large ones?

• Is it possible to set properties on a Mock Object in Simpletest

  - by JW

  I normally use getter and setter methods on my objects and I am fine with testing them as mock objects in SimpleTest by manipulating them with code like: Mock::generate('MyObj'); $MockMyObj->setReturnValue('getPropName', 'value') However, I have recently started to use magic interceptors (__set() __get()) and access properties like so: $MyObj->propName = 'blah'; But I am having difficulty making a mock object have a particular property accessed by using that technique. So is there some special way of setting properties on MockObjects. I have tried doing: $MockMyObj->propName = 'test Value'; but this does not seem to work. Not sure if it is my test Subject, Mock, magic Interceptors, or SimpleTest that is causing the property to be unaccessable. Any advice welcome.

• Detecting syllables in a word

  - by user50705

  I need to find a fairly efficient way to detect syllables in a word. E.g., invisible - in-vi-sib-le There are some syllabification rules that could be used: V CV VC CVC CCV CCCV CVCC *where V is a vowel and C is a consonant. e.g., pronunciation (5 Pro-nun-ci-a-tion; CV-CVC-CV-V-CVC) I've tried few methods, among which were using regex (which helps only if you want to count syllables) or hard coded rule definition (a brute force approach which proves to be very inefficient) and finally using a finite state automata (which did not result with anything useful). The purpose of my application is to create a dictionary of all syllables in a given language. This dictionary will later be used for spell checking applications (using Bayesian classifiers) and text to speech synthesis. I would appreciate if one could give me tips on an alternate way to solve this problem besides my previous approaches. I work in Java, but any tip in C/C++, C#, Python, Perl... would work for me.

• Rails after_create callback can't access model's attributes

  - by tybro0103

  I can't access my model's attributes in the after_create callback... seems like I should be able to right? controller: @dog = Dog.new(:color => 'brown', :gender => 'male') @dog.user_id = current_user.id @dog.save model: class Dog < ActiveRecord::Base def after_create logger.debug "[DOG CREATED] color:#{color} gender:#{gender} user:#{user_id}" end end console: (all seems well) >>Dog.last =>#<Dog id: 1, color: "brown", gender: "male", user_id: 1> log: (wtf!?) ... [DOG CREATED] color: gender:male user ... Some of my attributes show up and others don't! oh no! Anyone know what I'm doing wrong? I've always been able to user after_create in such ways in the past. Note: The actual variable names and values I used were different, but the methods and code are the same.

• Using boost.python to import a method with opencv calls but failing due to symbols not being found a

  - by nmz787

  So I don't have the code right now, as I am not home... but i used the boost library for python in C++ to allow python to access a function called something like loadImageIntoMainWindow(string filepath) in the C++ source code the method calls opencv methods that are imported at the top of the file, I included opencv in my Jamroot file, and also found a way to compile and link manually on the command line... in either case when I run my python file it complains that the symbols aren't found for the first function call to an opencv method... I will update as soon as I get home with the C++, the command line compilation lines, the Jamroot, and the python files

• improving conversions to binary and back in C#

  - by Saad Imran.

  I'm trying to write a general purpose socket server for a game I'm working on. I know I could very well use already built servers like SmartFox and Photon, but I wan't to go through the pain of creating one myself for learning purposes. I've come up with a BSON inspired protocol to convert the the basic data types, their arrays, and a special GSObject to binary and arrange them in a way so that it can be put back together into object form on the client end. At the core, the conversion methods utilize the .Net BitConverter class to convert the basic data types to binary. Anyways, the problem is performance, if I loop 50,000 times and convert my GSObject to binary each time it takes about 5500ms (the resulting byte[] is just 192 bytes per conversion). I think think this would be way too slow for an MMO that sends 5-10 position updates per second with a 1000 concurrent users. Yes, I know it's unlikely that a game will have a 1000 users on at the same time, but like I said earlier this is supposed to be a learning process for me, I want to go out of my way and build something that scales well and can handle at least a few thousand users. So yea, if anyone's aware of other conversion techniques or sees where I'm loosing performance I would appreciate the help. GSBitConverter.cs This is the main conversion class, it adds extension methods to main datatypes to convert to the binary format. It uses the BitConverter class to convert the base types. I've shown only the code to convert integer and integer arrays, but the rest of the method are pretty much replicas of those two, they just overload the type. public static class GSBitConverter { public static byte[] ToGSBinary(this short value) { return BitConverter.GetBytes(value); } public static byte[] ToGSBinary(this IEnumerable<short> value) { List<byte> bytes = new List<byte>(); short length = (short)value.Count(); bytes.AddRange(length.ToGSBinary()); for (int i = 0; i < length; i++) bytes.AddRange(value.ElementAt(i).ToGSBinary()); return bytes.ToArray(); } public static byte[] ToGSBinary(this bool value); public static byte[] ToGSBinary(this IEnumerable<bool> value); public static byte[] ToGSBinary(this IEnumerable<byte> value); public static byte[] ToGSBinary(this int value); public static byte[] ToGSBinary(this IEnumerable<int> value); public static byte[] ToGSBinary(this long value); public static byte[] ToGSBinary(this IEnumerable<long> value); public static byte[] ToGSBinary(this float value); public static byte[] ToGSBinary(this IEnumerable<float> value); public static byte[] ToGSBinary(this double value); public static byte[] ToGSBinary(this IEnumerable<double> value); public static byte[] ToGSBinary(this string value); public static byte[] ToGSBinary(this IEnumerable<string> value); public static string GetHexDump(this IEnumerable<byte> value); } Program.cs Here's the the object that I'm converting to binary in a loop. class Program { static void Main(string[] args) { GSObject obj = new GSObject(); obj.AttachShort("smallInt", 15); obj.AttachInt("medInt", 120700); obj.AttachLong("bigInt", 10900800700); obj.AttachDouble("doubleVal", Math.PI); obj.AttachStringArray("muppetNames", new string[] { "Kermit", "Fozzy", "Piggy", "Animal", "Gonzo" }); GSObject apple = new GSObject(); apple.AttachString("name", "Apple"); apple.AttachString("color", "red"); apple.AttachBool("inStock", true); apple.AttachFloat("price", (float)1.5); GSObject lemon = new GSObject(); apple.AttachString("name", "Lemon"); apple.AttachString("color", "yellow"); apple.AttachBool("inStock", false); apple.AttachFloat("price", (float)0.8); GSObject apricoat = new GSObject(); apple.AttachString("name", "Apricoat"); apple.AttachString("color", "orange"); apple.AttachBool("inStock", true); apple.AttachFloat("price", (float)1.9); GSObject kiwi = new GSObject(); apple.AttachString("name", "Kiwi"); apple.AttachString("color", "green"); apple.AttachBool("inStock", true); apple.AttachFloat("price", (float)2.3); GSArray fruits = new GSArray(); fruits.AddGSObject(apple); fruits.AddGSObject(lemon); fruits.AddGSObject(apricoat); fruits.AddGSObject(kiwi); obj.AttachGSArray("fruits", fruits); Stopwatch w1 = Stopwatch.StartNew(); for (int i = 0; i < 50000; i++) { byte[] b = obj.ToGSBinary(); } w1.Stop(); Console.WriteLine(BitConverter.IsLittleEndian ? "Little Endian" : "Big Endian"); Console.WriteLine(w1.ElapsedMilliseconds + "ms"); } Here's the code for some of my other classes that are used in the code above. Most of it is repetitive.

• How to get global variable in JQuery functions

  - by Tahir Akram

  I want to access my global javascript variable in JQuery methods. But I am unable to get it when I go to attach a click even to a div. As following. How can I do that? I mean do I need to rely on hidden fields for some state management? var divCount = 3; $(function() { //divCount is accessible here $("#sortable").sortable({ revert: true }); $("#new").click(function(){ if (divCount<7){ //divCount is not accessible here. why? and how? var thisCount = ++divCount; $("#draggable_"+thisCount).addClass("draggable"); } }); });

• Localization as an afterthought-- screwed?

  - by David

  So I signed on with a startup web development company as a subcontractor. They are putting together a large, complex user/product management system for a company that needs to support multiple levels of hierarchial localization. I signed a 3 month contract, and upon looking at their code, wish I hadn't. They opted to write their own MVC framework (I guess the client company didn't want to use a prewritten one) and it's extremely poorly written. There's SQL scattered throughout almost every model view and controller (and there's no parameter-based find methods, it's all SQL) and they haven't even THOUGHT about localization yet-- something that will have an affect on nearly EVERY query. The due date is 4 months away, and I honestly think we'd make good progress by scrapping the whole thing and going with CakePHP. Have any of you been in a similar situation, and what did you do? PS: This is written in PHP/MySQL.

• No method found compiler warning

  - by Magic Bullet Dave

  I have create a class from a string, check it is valid and then check if it responds to a particular method. If it does then I call the method. It all works fine, except I get an annoying compiler warning: "warning: no '-setCurrentID:' method found". Am I doing something wrong here? Is there anyway to tell the compiler all is ok and stop it reporting a warning? The here is the code: // Create an instance of the class id viewController = [[NSClassFromString(class) alloc] init]; // Check the class supports the methods to set the row and section if ([viewController respondsToSelector:@selector(setCurrentID:)]) { [viewController setCurrentID:itemID]; } // Push the view controller onto the tab bar stack [self.navigationController pushViewController:viewController animated:YES]; [viewController release]; Cheers Dave

• UILabel reset after Autorotate

  - by MB

  Hi, I have a UILabel in a view that is set by calling a method against my view controller. The app is a TABBar app and the VC is in the MORE section. When I rotate the phone the label disappears (don't mind that) when I rotate back the label is showing all .......... (the value it is set to in the XIB) I added a line to set the label in the shouldAutoRotateToOrientation method lblProductTxt.titleLabel.text = self.productText; when autorotating what viewcontroller methods are being called. ?? the shouldAutoRotateToOrientation method doesn't get called when the VC is in the More section but when I move it it does get called but has no affect on the labeltext

• How Can I Add a New Command to a Control's Event

  - by Chris

  Hi, thanks for taking a look at this question. I have been building an application (VB/WPF) following Josh Smith's example of an MVVM pattern: Click here to view My Views have Controls which trigger a Command upon an event, such as a button click and these are bound to properties in the ViewModel. My ViewModel exposes properties of type ICommand which invoke the appropriate methods. This has worked well, until now! I now want to use a Thumb Control to allow a user to move an object within a Canvas. I don't believe that the Thumb has a Command capability 'out of the box'. A Thumb raises a 'DragDelta' event when being moved. So my question is as follows: How do I extend a Control's capability to issue a Command upon an event please? I wish to issue a new Command, let's say 'onDragDelta' so that I can bind it to a property in my ViewModel just like my Buttons. Thank you very much

• WCF Client Proxy State

  - by RemotecUk

  Hi, how do I test the state of my proxy before making calls to my WCF service. I have a duplex channel created using a duplex channel factory. Before making any calls to the server I want to check the state of the proxy object created from the channel factory. I saw this in a book... (to be used in immediate window) ? ((ICommunicationObject)flsProxy).State But it gave this exception... Cannot obtain fields or call methods on the instance of type 'System.ServiceModel.ICommunicationObject' because it is a proxy to a remote object. Would be grateful for any ideas how this can be tested, or is it better to just catch exceptions. Thanks.

• Call the cast operator of template base class within the derived class

  - by yoni

  I have a template class, called Cell, here the definition: template <class T> class OneCell { ..... } I have a cast operator from Cell to T, here virtual operator const T() const { ..... } Now i have derived class, called DCell, here template <class T> class DCell : public Cell<T> { ..... } I need to override the Cell's cast operator (insert a little if), but after I need to call the Cell's cast operator. In other methods it's should be something like virtual operator const T() const { if (...) { return Cell<T>::operator const T; } else throw ... } but i got a compiler error error: argument of type 'const int (Cell::)()const' does not match 'const int' What can I do? Thank you, and sorry about my poor English.

• Why C# calls different overloaded method for different values of same type?

  - by Fabio Veronez

  Hello all, I have one doubt concerning c# method overloading call resolution. Let's suppose I have the following C# code: enum MyEnum { Value1, Value2 } public void test() { method(0); // this calls method(MyEnum) method(1); // this calls method(object) } public void method(object o) { } public void method(MyEnum e) { } Note that I know how to make it work but I would like to know why for one value of int (0) it calls one method and for another (1) it calls another. It sounds awkward since both values have the same type (int) but they are "linked" for different methods. Ps.: This is my first question here, i'm sorry if I made something wrong. =P

• Setting refresh-policies in Ehcache

  - by Alex Ciminian

  Is there any to specify a data refresh policy in Ehcache? I am currently migrating an application from OSCache to Ehcache and I can't seem to find any way to specify when an element needs refreshing, besides setting timeToIdle and timeToLive. What I want is: on accessing an element from the cache, check with it's associated resource to see if it was updated later than the lastUpdateTime of the cache element. If yes, refresh the cache; else serve the content from the cache. In OSCache this was done by catching NeedsRefreshExceptions and setting custom refresh policies for the elements. I've been digging around in the docs for a while now, but I wasn't able to find any methods or examples of how I could accomplish this in Ehcache. Any help would be appreciated :). Alex

• entity framework inserting a many-to-many relationship between two existing objects while updating

  - by redbluegreen

  I'm trying to do this: using(var context = new SampleEntities()) { User user = select a user from database; //Update user's properties user.Username = ... user.Website = ... //Add a role Role role = select a role from database //trying to insert into table UserRoles which has columns (UserID, RoleID) user.Roles.Add(role); //Apply property changes context.ApplyPropertyChanges("Users", user); context.SaveChanges(); } However, I get an exception telling me that "The existing object in the ObjectContext is in the Added state" and can't "ApplyPropertyChanges". If "ApplyPropertyChanges()" is removed, it adds a User. What orders should these methods be called? I don't need to do them separately right? Thanks.

• Enabling full documentation for J2EE in eclipse

  - by maayank

  I'm new to Eclipse and am using it currently to play with J2EE. When using Ctrl+Space for types/functions from the regular Java libraries I get a full description (i.e. general description of the type, what are the arguments of the method for, etc.). However I don't get the same for J2EE types. For example, when using Ctrl+Space on methods of the HttpSession class I get only names like "arg0" or "obj" and no description. Is there some kind of a package I can install to remedy this?

• Clarification required re use of .NET Assemblies in GAC - Use to use Globally?

  - by Cognize

  Hi, I've done much reading and experimentation today regarding sigining of assemblies, and their installation into the GAC via various methods (mscorcfg.msc / drag and drop). What I thought, was that once a file was in the GAC, you did not need to make references from projects in Visual studio. I know that you CAN make references via the usual Add Reference, Browse etc, but I thought it was automatic. Testing proves this not to be the case. I came across a forum post looking to achieve the same outcome that suggested adding to the machine.config file under system.web as below. This did not work, it in fact broke visual studio until I removed it. <assemblies> <add assembly="Blah.Framework.Logging, Version=1.0.3806.25580, Culture=neutral, PublicKeyToken=0beed4b631ebc3cd" /> </assemblies> What I want to know, is am I right in my assumed use of assemblies in the GAC, and is there a way of making them globally available?

• haystack's RealTimeSearchIndex causes django to hang on data entry

  - by lsc

  I'm using django-haystack and a xapian backend with real time indexing (haystack.indexes.RealTimeSearchIndexing) of model data and it works fine on my Ubuntu server. However, it causes django to hang upon data entry when I deployed the app on a RHEL5 server. Everything is hunky dory if I switch to a standard SearchIndex. Running ./manage.py rebuild_index manually works fine too. The major differences between the two setups would be the versions of Python (2.4.3 vs 2.6.4) and the xapian (1.0.4-1 vs 1.0.15). Any suggestions on what may be the problem? Nothing interesting appears in the logs, and I've tried different databases (mysql, sqlite3) and deployment methods (mod_python, wsgi) with no luck yet. I have noted the warning on the haystack docs stating that RealTimeSearchIndex is only handled gracefully with a Solr backend, however I'm running a very traffic site with only occasional writes so I'm fine with some CPU overheads on writes.

• What exactly is a property in Objective C ? What is the difference between a property ans an instance variable?

  - by tek3

  I am very much confused between instance variables and property. I have read number of posts regarding this but still i am not clear about it. I am from JAVA background and what i infer from objective C documentation is that a property is similar to JAVA BEAN CLASS (one having getter and setter of instance varibles). A property can accessed from other classes through its getter and setter methods while an instance variable is private and cannot be accessed from other classes. Am i right in thinking in this direction ?

• Modifying JSF Component Tree in PhaseListener

  - by jamiebarrow

  Hi all, I'm having an issue. I've implemented a PhaseListener, which is meant to add a style class to any UIInput components in the tree that have messages attached to them, and removes the style class if it doesn't have any messages attached to them. The PhaseListener runs in the RENDER_RESPONSE phase, and does it's work in both the beforePhase and afterPhase methods while debugging. While debugging, I found that beforePhase doesn't have access to the full component tree, but afterPhase does. Any changes done in afterPhase aren't rendered though. How do I go about this? I want this to be completely server side. Thanks, James
