• Use Hudson Build Parameter in Grails Build Target

  - by Stephen Swensen

  I have created two Hudson String Parameters in my parametrized build configuration: svnRoot, and svnBranch. I can reference these just fine when specifying my Repository URL: ${svnRoot}/${svnBranch}/subProject. But I have not been able to reference them as part of my Grails Build Target: "build-applet ${svnRoot}/${svnBranch}/appletProject username password" "war --non-interactive". build-applet invokes a Gant script in the Grails project at scripts\BuildApplet.groovy. This attempt yields the following error: groovy.lang.MissingPropertyException: No such property: svnRoot for class: Script1 at org.codehaus.groovy.runtime.ScriptBytecodeAdapter.unwrap(ScriptBytecodeAdapter.java:49) at org.codehaus.groovy.runtime.callsite.PogoGetPropertySite.getProperty(PogoGetPropertySite.java:49) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.callGroovyObjectGetProperty(AbstractCallSite.java:240) at Script1.run(Script1.groovy:1) at groovy.lang.GroovyShell.evaluate(GroovyShell.java:561) at groovy.lang.GroovyShell.evaluate(GroovyShell.java:536) at com.g2one.hudson.grails.GrailsBuilder.evalTarget(GrailsBuilder.java:212) at com.g2one.hudson.grails.GrailsBuilder.perform(GrailsBuilder.java:168) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:19) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:603) at hudson.model.Build$RunnerImpl.build(Build.java:172) at hudson.model.Build$RunnerImpl.doRun(Build.java:137) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:417) at hudson.model.Run.run(Run.java:1337) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:140) What is the best and or easiest way to achieve my goal?

• Log4Net and GAC - How to reference Configuraition Files?

  - by Adam

  Hello all I am using log4net during my development, as as part of a project constraint, I now need to add it to the Global Assembly Cache. The logging definitions are in a file Log4Net.xml. That file is referenced in my assemblyinfo as: [assembly: log4net.Config.XmlConfigurator(ConfigFile = "Log4Net.xml", Watch = true)]. So long as the xml file was in the same directory as the log4net.dll, everything has been working fine. However now that I've added log4net to the GAC, it is no longer picking up the xml file. Does anyone know what I need to change in order to have it pick up the XML file again? Is hardcoding the patch in the assembly reference the only way? Many thanks

• Call a macro every time any method is called - Objective C

  - by Jacob Relkin

  Hi, I wrote a debug macro that prints to the console the passed-in string whenever the global kDebug flag == YES. I need to print out the name of a method and it's classname whenever any method is called. That works fine when i painstakingly go through every method and write the name of the class and the method in a string. Is there any special handler that gets called when any method in Objective-C is called, and if so, is there a way i can somehow override it to call my debug macro?? The entire purpose of this is so that I don't have to go through every method in my code and hand-code the method signature in the debug macro call. Thanks

• Defining a dd/mm/yyyy field within an abstract table model

  - by Simon Andi

  I have defined an abstract table model but one of the columns should house date values as dd/mm/yyyy format not sure how to do this. I have a external global file and have hard coded the dates as dd/mm/yyyy. How can I define this column within my abstract table model so that to only allow only dates having dd/mm/yyyy format. public class OptraderGlobalParameters { public static boolean DEBUG = true; //Set DEBUG = true for Debugging /*=========================*/ /*Table Array For Dividends*/ /*=========================*/ public static String[] columnNames = {"Date", "Dividend", "Actual", "Yield (%)" }; public static Object[][] data = { {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)}, {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)}, {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)}, {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)}, {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)}, }; }

• Using Application Settings and reading defaults from app.config

  - by Peter Goras

  Hi, I need to deploy a Windows Forms application using ClickOnce deployment. (VS2008, .NET 3.5) And I need to provide a configuration file for this app that any user can modify. For this reason, I am using Application Settings instead of standard appSetttings in app.config so I can separate the the user config from app config. see http://msdn.microsoft.com/en-us/library/ms228995(VS.80).aspx Creating a Settings.settings file using VS generated a class with hard-coded default values like this: [global::System.Configuration.DefaultSettingValueAttribute("blahblah")] public string MyProperty ... WTF? I want to read the default values from the app.config! So I created my own class deriving from ApplicationSettingsBase but I cannot get this to read values from the app.config. Any ideas?

• Need to determine if ELMAH is logging an unhandled exception or one raised by ErrorSignal.Raise()

  - by Ronnie Overby

  I am using the Elmah Logged event in my Global.asax file to transfer users to a feedback form when an unhandled exception occurs. Sometimes I log other handled exceptions. For example: ErrorSignal.FromCurrentContext().Raise(new System.ApplicationException("Program code not found: " + Student.MostRecentApplication.ProgramCode)); // more code that should execute after logging this exception The problem I am having is that the Logged event gets fired for both unhandled and these handled, raised exceptions. Is there a way to determine, in the Logged event handler, whether the exception was raised via ErrorSignal class or was simply unhandled? Are there other Elmah events that I can take advantage of?

• Dynamic scoping in Clojure?

  - by j-g-faustus

  Hi, I'm looking for an idiomatic way to get dynamically scoped variables in Clojure (or a similar effect) for use in templates and such. Here is an example problem using a lookup table to translate tag attributes from some non-HTML format to HTML, where the table needs access to a set of variables supplied from elsewhere: (def *attr-table* ; Key: [attr-key tag-name] or [boolean-function] ; Value: [attr-key attr-value] (empty array to ignore) ; Context: Variables "tagname", "akey", "aval" '( ; translate :LINK attribute in <a> to :href [:LINK "a"] [:href aval] ; translate :LINK attribute in <img> to :src [:LINK "img"] [:src aval] ; throw exception if :LINK attribute in any other tag [:LINK] (throw (RuntimeException. (str "No match for " tagname))) ; ... more rules ; ignore string keys, used for internal bookkeeping [(string? akey)] [] )) ; ignore I want to be able to evaluate the rules (left hand side) as well as the result (right hand side), and need some way to put the variables in scope at the location where the table is evaluated. I also want to keep the lookup and evaluation logic independent of any particular table or set of variables. I suppose there are similar issues involved in templates (for example for dynamic HTML), where you don't want to rewrite the template processing logic every time someone puts a new variable in a template. Here is one approach using global variables and bindings. I have included some logic for the table lookup: ;; Generic code, works with any table on the same format. (defn rule-match? [rule-val test-val] "true if a single rule matches a single argument value" (cond (not (coll? rule-val)) (= rule-val test-val) ; plain value (list? rule-val) (eval rule-val) ; function call :else false )) (defn rule-lookup [test-val rule-table] "looks up rule match for test-val. Returns result or nil." (loop [rules (partition 2 rule-table)] (when-not (empty? rules) (let [[select result] (first rules)] (if (every? #(boolean %) (map rule-match? select test-val)) (eval result) ; evaluate and return result (recur (rest rules)) ))))) ;; Code specific to *attr-table* (def tagname) ; need these globals for the binding in html-attr (def akey) (def aval) (defn html-attr [tagname h-attr] "converts to html attributes" (apply hash-map (flatten (map (fn [[k v :as kv]] (binding [tagname tagname akey k aval v] (or (rule-lookup [k tagname] *attr-table*) kv))) h-attr )))) (defn test-attr [] "test conversion" (prn "a" (html-attr "a" {:LINK "www.google.com" "internal" 42 :title "A link" })) (prn "img" (html-attr "img" {:LINK "logo.png" }))) user=> (test-attr) "a" {:href "www.google.com", :title "A link"} "img" {:src "logo.png"} This is nice in that the lookup logic is independent of the table, so it can be reused with other tables and different variables. (Plus of course that the general table approach is about a quarter of the size of the code I had when I did the translations "by hand" in a giant cond.) It is not so nice in that I need to declare every variable as a global for the binding to work. Here is another approach using a "semi-macro", a function with a syntax-quoted return value, that doesn't need globals: (defn attr-table [tagname akey aval] `( [:LINK "a"] [:href ~aval] [:LINK "img"] [:src ~aval] [:LINK] (throw (RuntimeException. (str "No match for " tagname))) ; ... more rules [(string? ~akey)] [] ))) Only a couple of changes are needed to the rest of the code: In rule-match?, when syntax-quoted the function call is no longer a list: - (list? rule-val) (eval rule-val) + (seq? rule-val) (eval rule-val) In html-attr: - (binding [tagname tagname akey k aval v] - (or (rule-lookup [k tagname] *attr-table*) kv))) + (or (rule-lookup [k tagname] (attr-table tagname k v)) kv))) And we get the same result without globals. (And without dynamic scoping.) Are there other alternatives to pass along sets of variable bindings declared elsewhere, without the globals required by Clojure's binding? Is there an idiomatic way of doing it, like Ruby's binding or Javascript's function.apply(context)?

• JSF : Better way to check for existence of <h:message for="id"/>

  - by user552809

  I have a form in which validation error message needs to be displayed below the input elements. The error needs to be highlighted by showing an error bubble around the error message and the input text. To achieve this, I need to check for the existence of h:messages for individual elements. I am able to check for the existence of global error messages as follows <h:panelGroup rendered="#{not empty facesContext.messages}"> </h:panelGroup> How I can check the same for specific client id (say first name). So something like faceContent.messages("creditCardNo") A solution I have currently is to create a custom resolver but was wondering if there is a better solution.

• Whats the scope of a c function defined within objective-c class?

  - by roja

  I was reading up about bypassing objective-c's messaging to gain performance (irrelevant to this specific question) when i found an interesting bit of code: #import <Cocoa/Cocoa.h> @interface Fib : NSObject { } - (long long) cFib: (NSUInteger) number; @end @implementation Fib // c implementation of fib long long cFibIMP(NSUInteger number) { return (number < 3) ? 1 : cFib(number - 1) + cFib(number - 2); } // method wrapper for c implementation of fib - (long long) cFib: (NSUInteger) number { return cFibIMP(number); } @end My question is; when using c function, within an objective-c object, what scope is the c function (cFibIMP in this particular case) placed in? Does the objective-c class encapsulate the c function removing change of name-clash or is the c function simply dumped into the global scope of the whole objective-c program?

• How to deploy ASP.NET MVC application in a shared hosting without losing the beautiful uri?

  - by ZX12R

  i am trying to upload an asp.net mvc application in a shared server. I don't have access to IIS. What i have done after reading from various sources is change the route method in the global.asax file as follows routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{controller}.aspx/{action}/{id}", new { action = "Index", id = "" } ); routes.MapRoute( "Root", "", new { controller = "Home", action = "Index", id = "" } ); it is working fine. but the problem is i have lost the beautiful uri here. is there a way to remove the ".aspx" behind the controller..? thanks in advance.:)

• Globbing with MinGW on Windows

  - by Neil Butterworth

  I have an application built with the MinGW C++ compiler that works something like grep - acommand looks something like this: myapp -e '.*' *.txt where the thing that comes after the -e switch is a regex, and the thing after that is file name pattern. It seems that MinGW automatically expands (globs in UNIX terms) the command line so my regex gets mangled. I can turn this behaviour off, I discovered, by setting the global variable _CRT_glob to zero. This will be fine for bash and other sensible shell users, as the shell will expand the file pattern. For MS cmd.exe users however, it looks like I will have to expand the file pattern myself. So my question - does anyone know of a globbing library (or facility in MinGW) to do partial command line expansion? I'm aware of the _setargv feature of the Windows CRT, but that expands the full command line. Please note I've seen this question, but it really does not address partial expansion.

• Best practices for querying an entire row in a database table? (MySQL / CodeIgniter)

  - by Walker

  Sorry for the novice question! I have a table called cities in which I have fields called id, name, xpos, ypos. I'm trying to use the data from each row to set a div's position and name. What I'm wondering is what's the best practice for dynamically querying an unknown amount of rows (I don't know how many cities there might be, I want to pull the information from all of them) and then passing the variables from the model into the view and then setting attributes with it? Right now I've 'hacked' a solution where I run a different function each time which pulls a value using a query ('SELECT id FROM cities;'), then I store that in a global array variable and pass it into view. I do this for each var so I have arrays called: city_idVar, city_nameVar, city_xposVar, city_yposVar then I know that the city_nameVar[0] matches up with city_xposVar[0] etc. Is there a better way?

• Simplest way to update a client-side javascript array variable during a ASP.NET AJAX postback in an

  - by Noel

  If I want to inject a globally scoped array variable into a page's client-side javascript during a full page postback, I can use: this.Page.ClientScript.RegisterArrayDeclaration("WorkCalendar", "\"" + date.ToShortDateString() + "\""); to declare and populate a client-side javascript array on the page. Nice and simple. But I want to do the same from a async postback from an UpdatePanel. The closest I can figure so far is to create a .js file that just contains the var declaration, update the file during the async postback, and then use a ScriptManagerProxy.Scripts.Add to add the .js file to the page's global scope. Is there anything simpler? r iz doin it wrong?

  I am using JasperReports 1.3.1 to print the report. I am sing eclipse and tomcat for development purpose. In eclipse, when i run the application, the below code will show the listed printer devices and print button. If i click the print button, the report is printing by selected device. PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet(); printRequestAttributeSet.add(MediaSizeName.ISO_A5); PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet(); JRPrintServiceExporter exporter = new JRPrintServiceExporter(); exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRPrintServiceExporterParameter.PRINT_REQUEST_ATTRIBUTE_SET, printRequestAttributeSet); exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE_ATTRIBUTE_SET, printServiceAttributeSet); exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, Boolean.FALSE); exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, Boolean.TRUE); exporter.exportReport(); Here I am passing jasperPrint as a parameter which i manually construted.Its working good My problem is: I created war file and pasted in tomcat Apache Software Foundation\Tomcat 6.0\webapps directory and started the tomcat by using services.msc. At this point, its not displaying the listed printer details and also not printing. I put some logger, I found that, the code is hanging with exporter.exportReport(); after this line code is not executing . Please suggest me for how to print from client side using jasper

• C#: How to Make it Harder for Hacker/Cracker to Get Around or Bypass the Licensing Check?

  - by Peter Lee

  Hi all, Suppose that the user has saved the License file under the Application.StartupPath, where all users can read. And then, every time when the app starts, it will check if it can find and verify the license file. If the app can find and verify, we let the user to continue with full functinalities. If not, we prompt a MessageBox showing "Unlicencsed, continue to use with trial version, functionalities limited." My question is, if I'm a hacker/cracker, I would try to get around or bypass the licensing check instead of cracking the license file, because, if we use RSA signature, it's very difficult to crack a license file. So where should we put the license check? thanks. Merry Christmas and Happy New Year! Peter P.S.: and also, is it safe if I put a global variable IsLicensed (true / false) to limit the functionalities? Is it easy for a hacker to change IsLicensed = true?

• Best build dir location to use in Xcode

  - by neoneye

  I'm consolidating my Xcode/TextMate setup and is interested in where you put your build dir. Some years ago I started out having the build dir in the same dir as my xcodeproj file. However it became a mess when my project became a multi project with a applications and frameworks and tests, so I started using ../build as the build dir, so that all the sub projects used the same dir. However Spotlight is indexing this build dir and TextMate's global find is unusable when there is a build dir in the project. I'm thinking either using ~/.build or /build as Xcode's build dir. What build dir do you use and why?

• nhibernate webforms with class library

  very new to nhibernate. I'm a little confused on where features should live. I have the following solution 1) MyProject.Web ( web forms application) 2) MyProject.Domain( class lib) - nhibernate.config - product.hbm.xml So is it correct I should put the following method in a IHttpModule? ( i can't use a global asax as it's use by the CMS i'm running ) Where should the connectionString live? HTTPModule in web forms application private static ISessionFactory CreateSessionFactory() { var cfg = new Configuration().Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "nhibernate.config")); cfg.SetProperty(NHibernate.Cfg.Environment.ConnectionStringName, System.Environment.MachineName); NHibernateProfiler.Initialize(); return cfg.BuildSessionFactory(); } nhibernate.config <?xml version="1.0" encoding="utf-8" ?> NHibernate.Dialect.MsSql2005Dialect NHibernate.Connection.DriverConnectionProvider NHibernate.Driver.SqlClientDriver 16 web NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle enter code here

• Performance Counters in Server Development

  - by Mubashar Ahmad

  Dear Gurus All you be agree with the value and worth of Performance Counters while developing and maintaining a server kind application I would like to know what is the best way to implement those, Specifically using C#? Usually performance counters have the following attributes They are shared global Writing requires locks to ensure Synchronization Reading Some times requires locks too. Is it better to update them Asynchronously and what is the best way to make them so. (I am planning to use the ThreadPool.QueuWorketItem function, pls tell me you opinion on this too.) If my question seems a bit vague can you just take the example of a HelloWorld Wcf service and i wanted to know following how many times its being hit overall and within a certain period Average/min/max Response Times overall and within a certain period. Moreover if any one knows about the Specialized way provided by DotNet or WCF then please let me know as well.

• Using static variable in function vs passing variable from caller

  - by Patrick

  I have a function which spawns various types of threads, one of the thread types needs to be spawned every x seconds. I currently have it like this: bool isTime( Time t ) { return t >= now(); } void spawner() { while( 1 ) { Time t = now(); if( isTime( t ) )//is time is called in more than one place in the real function { launchthread() t = now() + offset; } } } but I'm thinking of changing it to: bool isTime() { static Time t = now(); if( t >= now() ) { t = now() + offset; return true; } return false; } void spawner() { if( isTime() ) launchthread(); } I think the second way is neater but I generally avoid statics in much the same way I avoid global data; anyone have any thoughts on the different styles?

• Thread Proc for an instancable class?

  Basically I have a class and it is instincable (not static). Basically I want the class to be able to generate its own threads and manage its own stuff. I don't want to make a global callback for each instance I make, this doesnt seem clean and proper to me. What is the proper way of doing what I want. If I try to pass the threadproc to CreateThread and it is the proc from a class instance the compiler says I cannot do this. What is the best way of achieving what I want? Thanks

• Tips on refactoring existing .net applications to support localization?

  - by Lee Warner

  We're going global. I've been tasked with refactoring our existing products to support localization. Last week I shunned using resource files (.resx) in favor of a home-baked database look-up method. After hitting a serious snag with that, I'm back to the microsoft way of using resx. All the documentation I've seen so far details how to create new "World-Ready" applications, but I don't see anything on changing existing applications. Is my only recourse to touch the application form by form and control by control to have it point to newly created resource files? Any good sources/links for internationalizing your apps?

• Exposing headers on iPhone static library

  - by leolobato

  Hello guys, I've followed this tutorial for setting up a static library with common classes from 3 projects we are working on. It's pretty simple, create a new static library project on xcode, add the code there, a change some headers role from project to public. The tutorial says I should add my library folder to the header search paths recursively. Is this the right way to go? I mean, on my library project, I have files separated in folders like Global/, InfoScreen/, Additions/. I was trying to setup one LOKit.h file on the root folder, and inside that file #import everything I need to expose. So on my host project I don't need to add the folder recursively to the header search path, and would just #import "LOKit.h". But I couldn't get this to work, the host project won't build complaining about all the classes I didn't add to LOKit.h, even though the library project builds. So, my question is, what is the right way of exposing header files when I setup a Cocoa Touch Static Library project on xCode?

• How to store a file on a server(web container) through a Java EE web application?

  - by Yatendra Goel

  I have developed a Java EE web application. This application allows a user to upload a file with the help of a browser. Once the user has uploaded his file, this application first stores the uploaded file on the server (on which it is running) and then processes it. At present, I am storing the file on the server as follows: try { FormFile formFile = programForm.getTheFile(); // formFile represents the uploaded file String path = getServlet().getServletContext().getRealPath("") + "/" + formFile.getFileName(); System.out.println(path); file = new File(path); outputStream = new FileOutputStream(file); outputStream.write(formFile.getFileData()); } where, the formFile represents the uploaded file. Now, the problem is that it is running fine on some servers but on some servers the getServlet().getServletContext().getRealPath("") is returning null so the final path that I am getting is null/filename and the file doesn't store on the server. When I checked the API for ServletContext.getRealPath() method, I found the following: public java.lang.String getRealPath(java.lang.String path) Returns a String containing the real path for a given virtual path. For example, the path "/index.html" returns the absolute file path on the server's filesystem would be served by a request for "http://host/contextPath/index.html", where contextPath is the context path of this ServletContext. The real path returned will be in a form appropriate to the computer and operating system on which the servlet container is running, including the proper path separators. This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive). So, Is there any other way by which I can store files on those servers also which is returning null for getServlet().getServletContext().getRealPath("")

• Issue in exec method

  Hi all, I am a having two python files file1.py and file2.py. I am using exec() to get the method/Variables defined in the file2.py. file1.py have a class as given below class one: def init(self): self.HOOK = None exec(file2.py) self.HOOK = Generate ### call the hook method #### self.HOOK() file2.py looks like as (There is no class define in file2.py) def Generate() do 1 do 2 Hello() def hello() print "hello" Now the problem is as When i run script it is giving a error global name Hello not found. If i remove Hello() from Generate method in file2.py then its work fine. I cant use import file2.py in file1.py,because in file2.py the only one method name (Generate) is fix (its taken as requirement). So apart from Genarate method user can define any method and can call this in generate method, because this approach is not working so i have to write whole code into generate method only and code is also repetitive. Any help is really appreciable...
