• Swing data binding frameworks

  - by Ahe

  Hi Almost the same question has been asked a year ago, but the there has been some new development in this area. Selecting a (data binding) framework for swing application seems to be quite difficult. JSR-295 is abandoned, many swing frameworks which provide binding are work-in-progress, abandoned or too heavy for my quite simple app. JGoodies Swing suite is expensive, but luckily its libraries are free. Has anyone any real-world experience of new UFaceKit. It looks promising, but quite immature. I am particularly interested in Swing implementation and documentation. Any insight on UFaceKits development schedule would be appreciated, because I can hold by framework choice for a while. Requirements are not anything fancy, just working binding with a nice API. I also found Mogwai dataBinding, but it seems quite incomplete and requires manual synchronization activation, which makes it useless compared to coarse grained synchronization easily written by hand. Incomplete frameworks include at least Spring RCP and many JSR-296 forks. So, is the JGoodies data binding really the only realistic choice? Or are there any other viable solutions available?

• Access and modify attributes/objects which are not part of the form backing bean

  - by spa

  I use Spring MVC (via Spring Roo) to build a small web application for administering persons. In the page for creating a person the bean Person is used as form backing object (key "person" in the model map). <form:form action="${form_url}" method="POST" modelAttribute="person"> I would like to add some attributes to the model map which can be altered by the user in the creation form. Basically, I try to add a Boolean, so that I can control which page is displayed next after the user presses the submit button. I try to modify the Boolean (key "myBoolean" in the model map) using a simple checkbox: <form:checkbox id="_myboolean_id" path="myBoolean"/> However, as I am new to Spring MVC I have some difficulties here. The Boolean object is not an attribute of the form backing object. So if I try to access it the following exception is thrown (of course): Invalid property 'myBoolean' of bean class [de.cm.model.Person]: Bean property 'myBoolean' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter? Is there are way to access a value of the model map directly? The only solution I can imagine right now is a kind of wrapper object around the class Person and my additional attributes which is used as a new form backing object. However, this is more work for a IMHO simple task. Do you have a better solution?

• How to deploy RSWebParts.cab manually?

  - by denni

  I'm using the SSRS 2005 Web parts to display my reports in a MOSS 2007 SP1 Portal. I have successfully installed the Web parts in my development, testing, and UAT servers using the following command: stsadm -o addwppack -filename path/to/RSWebParts.cab. But when I tried running the same command in the production server, it will give me the following error: This solution contains no resources scoped for a Web application and cannot be deployed to a particular Web application. I know I usually will get this kind of error message when I tried to deploy my custom solutions having no Web application resources (such as web.config entries) to a specific Web application. But this is not my custom solution, it is an out-of-the-box SSRS Web part and it does have resources scoped to a Web application. I tried to even use different combination of the command by providing the -url, -globalinstall, and -force switches but it still give the same error. The configuration of the 4 servers are exactly the same, both from software and hardware perspectives. All other features are working properly on the production server. I even tried to extract the cab file manually to the bin folder of my Web application, then modify the Web.config manually to include the SafeControl element (copied from the manifest.xml inside the cab file). But it gave me an error saying it couldn't find the resources file. Even though, I extracted the whole file, including the resource files in the bin folder. Is there anyone who can help me resolve the problem? Thanks a lot.

• XCTest.framework build error

• IoC & Interfaces Best Practices

  - by n8wrl

  I'm experimenting with IoC on my way to TDD by fiddling with an existing project. In a nutshell, my question is this: what are the best practices around IoC when public and non-public methods are of interest? There are two classes: public abstract class ThisThingBase { public virtual void Method1() {} public virtual void Method2() {} public ThatThing GetThat() { return new ThatThing(this); } internal virtual void Method3() {} internal virtual void Method4() {} } public class Thathing { public ThatThing(ThisThingBase thing) { m_thing = thing; } ... } ThatThing does some stuff using its ThisThingBase reference to call methods that are often overloaded by descendents of ThisThingBase. Method1 and Method2 are public. Method3 and Method4 are internal and only used by ThatThings. I would like to test ThatThing without ThisThing and vice-versa. Studying up on IoC my first thought was that I should define an IThing interface, implement it by ThisThingBase and pass it to the ThatThing constructor. IThing would be the public interface clients could call but it doesn't include Method3 or Method4 that ThatThing also needs. Should I define a 2nd interface - IThingInternal maybe - for those two methods and pass BOTH interfaces to ThatThing?

• Overriding MSBuildExtensionsPath in the MSBuild task is flaky

  - by Stuart Lange

  This is already cross-posted at MS Connect: https://connect.microsoft.com/VisualStudio/feedback/details/560451 I am attempting to override the property $(MSBuildExtensionsPath) when building a solution containing a C# web application project via msbuild. I am doing this because a web application csproj file imports the file "$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets". This file is installed by Visual Studio to the standard $(MSBuildExtensionsPath) location (C:\Program Files\MSBuild). I would like to eliminate the dependency on this file being installed on the machine (I would like to keep my build servers as "clean" as possible). In order to do this, I would like to include the Microsoft.WebApplication.targets in source control with my project, and then override $(MSBuildExtensionsPath) so that the csproj will import this included version of Microsoft.WebApplication.targets. This approach allows me to remove the dependency without requiring me to manually modify the web application csproj file. This scheme works fine when I build my solution file from the command line, supplying the custom value of $(MSBuildExtensionsPath) at the command line to msbuild via the /p flag. However, if I attempt to build the solution using the MSBuild task in a custom msbuild project file (overriding MSBuildExtensionsPath using the "Properties" attribute), it fails because the web app csproj file is attempting to import the Microsoft.WebApplication.targets from the "standard" Microsoft.WebApplication.targets location (C:\Program Files\MSBuild). Notably, if I run msbuild using the "Exec" task in my custom project file, it works. Even more notably, the FIRST time I run the build using the "MSBuild" task AFTER I have run the build using the "EXEC" task (or directly from the command line), the build works. Has anyone seen behavior like this before? Am I crazy? Is anyone aware of the root cause of this problem, a possible workaround, or whether this is a legitimate bug in MSBuild?

• Distutils - Where Am I going wrong?

  - by RJBrady

  I wanted to learn how to create python packages, so I visited http://docs.python.org/distutils/index.html. For this exercise I'm using Python 2.6.2 on Windows XP. I followed along with the simple example and created a small test project: person/ setup.py person/ __init__.py person.py My person.py file is simple: class Person(object): def __init__(self, name="", age=0): self.name = name self.age = age def sound_off(self): print "%s %d" % (self.name, self.age) And my setup.py file is: from distutils.core import setup setup(name='person', version='0.1', packages=['person'], ) I ran python setup.py sdist and it created MANIFEST, dist/ and build/. Next I ran python setup.py install and it installed it to my site packages directory. I run the python console and can import the person module, but I cannot import the Person class. >>>import person >>>from person import Person Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: cannot import name Person I checked the files added to site-packages and checked the sys.path in the console, they seem ok. Why can't I import the Person class. Where did I go wrong?

• Problem with MessageContract, Generic return types and clientside naming

  - by Soeteman

  I'm building a web service which uses MessageContracts, because I want to add custom fields to my SOAP header. In a previous topic, I learned that a composite response has to be wrapped. For this purpose, I devised a generic ResponseWrapper class. [MessageContract(WrapperNamespace = "http://mynamespace.com", WrapperName="WrapperOf{0}")] public class ResponseWrapper<T> { [MessageBodyMember(Namespace = "http://mynamespace.com")] public T Response { get; set; } } I made a ServiceResult base class, defined as follows: [MessageContract(WrapperNamespace = "http://mynamespace.com")] public class ServiceResult { [MessageBodyMember] public bool Status { get; set; } [MessageBodyMember] public string Message { get; set; } [MessageBodyMember] public string Description { get; set; } } To be able to include the request context in the response, I use a derived class of ServiceResult, which uses generics: [MessageContract(WrapperNamespace = "http://mynamespace.com", WrapperName = "ServiceResultOf{0}")] public class ServiceResult<TRequest> : ServiceResult { [MessageBodyMember] public TRequest Request { get; set; } } This is used in the following way [OperationContract()] ResponseWrapper<ServiceResult<HCCertificateRequest>> OrderHealthCertificate(RequestContext<HCCertificateRequest> context); I expected my client code to be generated as ServiceResultOfHCCertificateRequest OrderHealthCertificate(RequestContextOfHCCertificateRequest context); Instead, I get the following: ServiceResultOfHCCertificateRequestzSOTD_SSj OrderHealthCertificate(CompType1 c1, CompType2 c2, HCCertificateRequest context); CompType1 and CompType2 are properties of the RequestContext class. The problem is that a hash is added to the end of ServiceResultOfHCCertificateRequestzSOTD_SSj. How do I need define my generic return types in order for the client type to be generated as expected (without the hash)?

• Hiring a programmer: looking for the "right attitude"

  - by Totophil

  It's actually two questions in one: What is the right attitude for a programmer? How do you (or would you) look for one when interviewing or during hiring process? Please note this question is not about personality or traits of a candidate, it is about their attitude towards what they do for living. This is also not about reverse of programmers pet peeves. The question has been made community wiki, since I am interested in a good answer rather than reputation. I disagree that the question is purely subjective and just a matter of opinion: clearly some attitudes make a better programmer than others. Consecutively, there might quite possibly exist an attitude that is common to the most of the better programmers. Update: After some deliberation I came up with the following attitude measurement scales: identifies themselves with the job ? fully detached perceives code as a collection of concepts ? sees code as a sequence of steps thinks of creating software as an art ? takes 100% rational approach to design and development Answers that include some sort of a comment on the appropriateness of these scales are greatly appreciated. Definition of "attitude": a complex mental state involving beliefs and feelings and values and dispositions to act in certain ways; "he had the attitude that work was fun" The question came as a result of some reflection on the top voted answer to "How do you ensure code quality?" here on Stack Overflow.

• Autodetect Presence of CSV Headers in a File

  - by banzaimonkey

  Short question: How do I automatically detect whether a CSV file has headers in the first row? Details: I've written a small CSV parsing engine that places the data into an object that I can access as (approximately) an in-memory database. The original code was written to parse third-party CSV with a predictable format, but I'd like to be able to use this code more generally. I'm trying to figure out a reliable way to automatically detect the presence of CSV headers, so the script can decide whether to use the first row of the CSV file as keys / column names or start parsing data immediately. Since all I need is a boolean test, I could easily specify an argument after inspecting the CSV file myself, but I'd rather not have to (go go automation). I imagine I'd have to parse the first 3 to ? rows of the CSV file and look for a pattern of some sort to compare against the headers. I'm having nightmares of three particularly bad cases in which: The headers include numeric data for some reason The first few rows (or large portions of the CSV) are null There headers and data look too similar to tell them apart If I can get a "best guess" and have the parser fail with an error or spit out a warning if it can't decide, that's OK. If this is something that's going to be tremendously expensive in terms of time or computation (and take more time than it's supposed to save me) I'll happily scrap the idea and go back to working on "important things". I'm working with PHP, but this strikes me as more of an algorithmic / computational question than something that's implementation-specific. If there's a simple algorithm I can use, great. If you can point me to some relevant theory / discussion, that'd be great, too. If there's a giant library that does natural language processing or 300 different kinds of parsing, I'm not interested.

• Amazon S3 and swfaddress

  - by justinbach

  I recently migrated a large AS3 site (lots of swfs, lots of flvs) to Amazon S3. Pretty much everything but HTML and JS files is being stored/served from Amazon, and it's working well. The only problem I'm having is that I built the site using SWFaddress (actually, via the Gaia framework which uses SWFaddress), and for some reason, SWFaddress is no longer updating the address bar correctly as users navigate from page to page. In other words, the URL persistently remains http://www.mysite.com, not http://www.mysite.com/#/section as would be the case were SWFaddress functioning correctly (and as it was functioning prior to the migration). Stranger yet, if I go to (e.g.) http://www.mysite.com/#/section directly, the deeplinking functions as you'd expect--I arrive directly at the correct section. However, navigating away from that section doesn't have any effect on the address bar, despite the fact that it should be dynamically updated. I've got a crossdomain.xml file set up on the site that allows access from all domains, so that's not the issue, and I don't know what else might be. Any ideas would be greatly appreciated! P.S. I integrated S3 by putting pretty much the entire site in an S3 bucket and then just changing the initial swfobject embed to point to the S3 instance of main.swf, passing in the S3 path as the "base" param to the embedded swf so that all dynamically loaded assets and swfs would also be sourced from s3. Dunno if that's related to the troubles I'm having.

• sqrt(int_value + 0.0) -- Does it have a purpose?

  - by Earlz

  Hello, while doing some homework in my very strange C++ book, which I've been told before to throw away, had a very peculiar code segment. I know homework stuff always throws in extra "mystery" to try to confuse you like indenting 2 lines after a single-statement for-loop. But this one I'm confused on because it seems to serve some real-purpose. basically it is like this: int counter=10; ... if(pow(floor(sqrt(counter+0.0)),2) == counter) ... I'm interested in this part especially: sqrt(counter+0.0) Is there some purpose to the +0.0? Is this the poormans way of doing a static cast to a double? Does this avoid some compiler warning on some compiler I do not use? The entire program printed the exact same thing and compiled without warnings on g++ whenever I left out the +0.0 part. Maybe I'm not using a weird enough compiler? Edit: Also, does gcc just break standard and not make an error for Ambiguous reference since sqrt can take 3 different types of parameters? [earlz@EarlzBeta-~/projects/homework1] $ cat calc.cpp #include <cmath> int main(){ int counter=0; sqrt(counter); } [earlz@EarlzBeta-~/projects/homework1] $ g++ calc.cpp /usr/lib/libstdc++.so.47.0: warning: strcpy() is almost always misused, please use strlcpy() /usr/lib/libstdc++.so.47.0: warning: strcat() is almost always misused, please use strlcat() [earlz@EarlzBeta-~/projects/homework1] $

• asp.Net 2005 "Could not load type"

  - by Melody Friedenthal

  Although I have seen dozens of forum questions relating to "Could not load type", none of the advice in them seemed to apply to my situation. I wrote a new web application using aspx.net VB 2005. It is tiny, with just 2 pages, 1 of which has no code-behind. It runs aok in the IDE but when I installed it on my pc (and also when installed on the production server), and tried to run it this error came up: Parser Error Description: An error occurred during the parsing of a resource required to service this request.

• Problem with RegEx.Replace and trying to change a filename

  - by fraXis

  Hello, I am having a strange problem and I can't seem to figure it out. My filename is something like this: DER 1513016-3.020F.NCF. I want to be able to change it to: DER 1513016-3.020H.NCF Sometimes the filename can be this as well: DER 1513016-3.020F_NEW.NCF which would change to: DER 1513016-3.020H_NEW.NCF This is my code to do this: OpenFileDialog fDialog = new OpenFileDialog(); fDialog.Title = "Open"; fDialog.Filter = "NCF files (*.ncf)|*.ncf|All files (*.*)|*.*"; fDialog.InitialDirectory = @"C:\Program Files\"; if (fDialog.ShowDialog() == DialogResult.OK) { string newfilename; string fileext = Path.GetExtension(fDialog.FileName); newfilename = Regex.Replace(fDialog.FileName, "F.NCF", "H.NCF"); newfilename = Regex.Replace(fDialog.FileName, "F_NEW.NCF", "H_NEW.NCF"); } This is where things get wierd. The way the code works now, it will NOT change the filename to DER 1513016-3.020H.NCF If I comment out this line of code: //newfilename = Regex.Replace(fDialog.FileName, "F_NEW.NCF", "H_NEW.NCF"); it will work fine and the file will now become: DER 1513016-3.020H.NCF However, if I uncomment that line of code, the filename will not change to DER 1513016-3.020H.NCF. It will stay as DER 1513016-3.020F.NCF. Why is that line of code causing the routine to not change the filename? Thanks,

• Retrieve Flash file post in ASP.NET

  - by Quandary

  Question: In ASP.NET, I retrieve a JPEG-file as Flash post data like this Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest context.Response.ContentType = "text/plain" ' Retrieve a bytearray from the post buffer Dim myBuffer As Byte() = context.Request.BinaryRead(Convert.ToInt32(context.Request.InputStream.Length)) System.IO.File.WriteAllBytes("c:\temp\test.jpg", myBuffer) End Sub In Flash, I send it to an asp.net handler like this var jpgSource:BitmapData = cPrint.TakeSnapshot(MovieClip(cGlobals.ccPlanZoomView)); var bmpThisBitmap:Bitmap = new Bitmap(jpgSource); var nQuality:Number = 100; var jpgEncoder:JPGEncoder = new JPGEncoder(nQuality); var jpgStream:ByteArray = jpgEncoder.encode(jpgSource); var header:URLRequestHeader = new URLRequestHeader ("Content-type", "application/octet-stream"); // Make sure to use the correct path to jpg_encoder_download.php var strFileName:String="test.jpg"; var jpgURLRequest:URLRequest = new URLRequest("http://localhost/raumplaner_new/raumplaner_new/cgi-bin/SavePDF.ashx"); //var scriptVars:URLVariables = new URLVariables(); //scriptVars.fn = strFileName; //var myarr:Array= new Array(); //myarr.push(jpgStream); //scriptVars.Files = myarr; jpgURLRequest.requestHeaders.push(header); jpgURLRequest.method = URLRequestMethod.POST; //jpgURLRequest.data = scriptVars; jpgURLRequest.data = jpgStream; var loader:URLLoader = new URLLoader(); loader.dataFormat = URLLoaderDataFormat.BINARY; loader.load(jpgURLRequest); It works but I want to send a few additional variables along, via scriptVars (commented out here). How do I retrieve the JPEG file in that case ? Because if I use parameters, there is no more BinaryRead... Aspecially, how would I read an array of jpeg files (several files) ?

• When and how should independent hierarchies be used in clojure?

  - by Rob Lachlan

  Clojure's system for creating an ad hoc hierarchy of keywords is familiar to most people who have spent a bit of time with the language. For example, most demos and presentations of the language include examples such as (derive ::child ::parent) and they go on to show how this can be used for multi-method dispatch. In all of the slides and presentations that I've seen, they use the global hierarchy. But it is possible to put keyword relationships in independent hierarchies, by using (derive h ::child ::parent), where h is created by (make-hierarchy). Some questions, therefore: Are there any guidelines on when this is useful or necessary? Are there any functions for manipulating hierarchies? Merging is particularly useful, so I do this: (defn merge-h [& hierarchies] (apply merge-with (cons #(merge-with clojure.set/union %1 %2) hierarchies)) But I was wondering if such functions already exist somewhere. EDIT: Changed "custom" hierarchy to "independent" hierarchy, since that term better describes this animal. Also, I've done some research and included my own answer below. Further comments are welcome.

• Database INSERT does not take place

  - by reggie

  My code is as follows: <?php include("config.php"); $ip=$_SERVER['REMOTE_ADDR']; if($_POST['id']) { $id=$_POST['id']; $id = mysql_escape_String($id); $ip_sql=mysql_query("select ip_add from Voting_IP where mes_id_fk='$id' and ip_add='$ip'"); $count=mysql_num_rows($ip_sql); if($count==0) { $sql = "update Messages set up=up+1 where mes_id='$id'"; mysql_query($sql); $sql_in = "insert into Voting_IP (mes_id_fk,ip_add) values ('$id','$ip')"; mysql_query($sql_in) or die(mysql_error()); echo "<script>alert('Thanks for the vote');</script>"; } else { echo "<script>alert('You have already voted');</script>"; } $result=mysql_query("select up from Messages where mes_id='$id'"); $row=mysql_fetch_array($result); $up_value=$row['up']; echo "<img src='button.png' width='110' height='90'>"; echo $up_value; } ?> My problem is that the insert process does not take place at all. The script tags echos an alert box. Even the img tag is echoed to the web page. But the insert process does not take place. The config file is fine. Note: This code works on my local machine which has PHP 5.3 but it does not work on the server which has PHP 5.2. Any advice?

• Probably an easy one - PHP/CodeIgniter 'Undefined Variable'

  - by Jack W-H

  Morning y'all This is probably an easy one but I barely got any sleep last night and am struggling to comprehend anything. I've got a CodeIgniter library I've made called Points.php. Here's the contents of Points: <?php if (!defined('BASEPATH')) exit('No direct script access allowed'); class Points { function __construct() { $this->ci =& get_instance(); $this->ci->load->database(); } function getpoints($params) { echo $userid; } } /* End of file Points.php */ /* Location: ./application/libraries/Points.php */ ?> As you can see, I'm building it up slowly and it's being kept simple. In one of my views, I want it to display the number of 'points' (which for the time being is simply the third segment of the URI). I call it like this: <p>Points: <?php $params['user_id']=$this->uri->segment(3,1); echo $this->points->getpoints($params); ?></p> The warning I get back in the view is this: A PHP Error was encountered Severity: Notice Message: Undefined variable: userid Filename: libraries/Points.php Yes I know it's such a simple problem but I've tried lots of things. Some variations include echoing in Points.php $params['userid']; etc. But I don't see what I'm doing wrong? This is my first CodeIgniter class and I've fallen at the first step, haha...

• Detecting Xml namespace fast

  - by Anna Tjsoken

  Hello there, This may be a very trivial problem I'm trying to solve, but I'm sure there's a better way of doing it. So please go easy on me. I have a bunch of XSD files that are internal to our application, we have about 20-30 Xml files that implement datasets based off those XSDs. Some Xml files are small (<100Kb), others are about 3-4Mb with a few being over 10Mb. I need to find a way of working out what namespace these Xml files are in order to provide (something like) intellisense based off the XSD. The implementation of this is not an issue - another developer has written the code for this. But I'm not sure the best (and fastest!) way of detecting the namespace is without the use of XmlDocument (which does a full parse). I'm using C# 3.5 and the documents come through as a Stream (some are remote files). All the files are *.xml (I can detect if it was extension based) but unfortunately the Xml namespace is the only way. Right now I've tried XmlDocument but I've found it to be innefficient and slow as the larger documents are awaiting to be parsed (even the 100Kb docs). public string GetNamespaceForDocument(Stream document); Something like the above is my method signature - overloads include string for "content". Would a RegEx (compiled) pattern be good? How does Visual Studio manage this so efficiently? Another college has told me to find a fast Xml parser in C/C++, parse the content and have a stub that gives back the namespace as its slower in .NET, is this a good idea?

• Creating cookieless application on development machine with asp.net

  I tried posting this on ServerFault with no luck so i am trying here. I am thinking about setting up a new domain to host static content on my website and have it cookieless just like Stackoverflow with their static domain. So before going ahead and buying the domain and setting it up I wanted to test it on my developement machine first under localhost (I have to mention that i am planning on having IIS running on my new domain for the static files). I therefore created a new application under IIS and disabled session state and forms authentication. When my main application needs resources like css, images and js , I use the path to the "static" application where they are hosted. The problem is that when I look at the request and the response for the requested files, they still have the session_id cookie defined as well as the asp.net authentication cookie. Is it at all possible to accomplish what i am trying to do on a development machine or do i have to just go ahead and purchase the new domain which hopefully with make things right? I tried to read about cookieless domain but can't figure out what i might be missing.

• what is the exact way to use Endorsed directory in jdk1.6

  - by raticulin

  I want to upgrade my jaxws to 2.2 (jdk1.6 comes bundled with jaxws 2.1). My jdk is (I did not install public jre): java version "1.6.0_20" Java(TM) SE Runtime Environment (build 1.6.0_20-b02) Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode) In jaxws' own doc they explain how to do it: One way to fix this is to copy jaxws-api.jar and jaxb-api.jar into JRE endorsed directory, which is $JAVA_HOME/lib/endorsed (or $JDK_HOME/jre/lib/endorsed) But I am not sure this is having any effect in my installation. For starters I have only defined %JAVA_HOME%. And folder $JAVA_HOME/lib/endorsed is inexistant, so I created and copied the two jars. But if I do (wsgen is a tool from jaxws) wsgen -version I still get: JAX-WS RI 2.1.6 in JDK 6 I also tried creating folder JAVA_HOME\jre\lib\endorsed (notice that in the doc they say JDK_HOME, but as I only have JAVA_HOME I used this path). Still same wsgen output. My questions are: What is the difference between JAVA_HOME and JDK_HOME in the doc page? anything significant or just two ways to refer to JAVA_HOME ? Is 'wsgen -version' a valid way to check jaxws version that is used or this always calls the exe in the original jdk, but it does not mean endorsed jars will be used? Anyone knows very detailed steps to install jaxws2.2 in a jdk.16?

• MYSQL Data -> PHP arrays -> Javascript (or Jquery) How can I pass the data with JSON ?

  - by Alex

  I am starting with a new site (it's my first one) and I am getting big troubles ! I wrote this code <?php include("misc.inc"); $cxn=mysqli_connect($host,$user,$password,$database) or die("couldn't connect to server"); $query="SELECT DISTINCT country FROM stamps"; $result=mysqli_query($cxn,$query) or die ("couldn't execute query"); $numberOfRows=mysqli_num_rows($result); for ($i=0;$i<$numberOfRows;$i++){ $row=mysqli_fetch_assoc($result); extract($row); $a=json_encode($row); $a=$a.","; echo $a; } ?> and the output is as follows : {"country":"liechtenstein"},{"country":"romania"},{"country":"jugoslavia"},{"country":"polonia"}, which should be a correct JSON outout ... How can I get it now in Jquery ? I tried with $.getJSON but I am not able to fuse it properly. I don't want yet to pass the data to a DIV or something similar in HTML. Alex

• Zend file upload error

  - by jgnasser

  I am attempting to upload a file using Zend Framework 1.8 and I get some errors. Here is the code snippet: The form element: $element = new Zend_Form_Element_File('doc'); $element->setLabel('Upload an image:') ->setDestination('/path/to/my/upload/folder'); $element->addValidator('Count', false, 1); $element->addValidator('Size', false, 102400); $element->addValidator('Extension', false, 'jpg,png,gif,doc,docx,xls,xlsx,txt'); $this->addElement($element); The code for handling the upload: $adapter = new Zend_File_Transfer_Adapter_Http(); if (!$adapter->receive()) { $messages = $adapter->getMessages(); echo implode("\n", $messages); } This works fine and the file is uploaded but I get the error "The file 'doc' was illegal uploaded, possible attack". I managed to get past this problem by not creating a new Zend_File_Transfer_Adapter_Http() but instead using: $adapter = $form->doc->getTransferAdapter(); With this modification, the first error disappears but now I have an error saying I have provided 2 files instead of one (probably its reading the temp) and when I adjust the validator to accept two files I then get the arror saying "The file 'doc' was not found" and the upload now fails completely. Please help

• Member initialization while using delegated constructor

  - by Anton

  I've started trying out the C++11 standard and i found this question which describes how to call your ctor from another ctor in the same class to avoid having a init method or the like. Now i'm trying the same thing with code that looks like this: hpp: class Tokenizer { public: Tokenizer(); Tokenizer(std::stringstream *lines); virtual ~Tokenizer() {}; private: std::stringstream *lines; }; cpp: Tokenizer::Tokenizer() : expected('=') { } Tokenizer::Tokenizer(std::stringstream *lines) : Tokenizer(), lines(lines) { } But this is giving me the error: In constructor ‘config::Tokenizer::Tokenizer(std::stringstream*)’: /path/Tokenizer.cpp:14:20: error: mem-initializer for ‘config::Tokenizer::lines’ follows constructor delegation I've tried moving the Tokenizer() part first and last in the list but that didn't help. What's the reason behind this and how should i fix it? I've tried moving the lines(lines) to the body with this->lines = lines; instead and it works fine. But i would really like to be able to use the initializer list. Thanks in advance!

• How to sort the file names in bash in this circumstance?

  - by Nicolas

  I have run a program to generate some results with the different parameters(i.e. the R, C and RP). These results are saved in files named results.txt. Then, I should parse these experimental results to make an analysis. In the params_R_7_C_16_RP_0, the 7 is the value of the parameter R, the 16 is the value of the parameter C and the 0 is the value of the parameter RP. Now, I want to get these results.txt files in the current directory to parse, and sort the path with the parameter values of R,C and RP. I first use the following command to get the results.txt files that I want to parse: find ./ -name "results.txt" and the output is: ./params_R_11_C_9_RP_0/results.txt ./params_R_7_C_9_RP_0/results.txt ./params_R_7_C_4_RP_0/results.txt ./params_R_11_C_16_RP_0/results.txt ./params_R_9_C_4_RP_0/results.txt ./params_R_5_C_9_RP_0/results.txt ./params_R_9_C_25_RP_0/results.txt ./params_R_7_C_16_RP_0/results.txt ./params_R_5_C_25_RP_0/results.txt ./params_R_5_C_16_RP_0/results.txt ./params_R_11_C_4_RP_0/results.txt ./params_R_9_C_16_RP_0/results.txt ./params_R_7_C_25_RP_0/results.txt ./params_R_15_C_4_RP_0/results.txt ./params_R_5_C_4_RP_0/results.txt ./params_R_9_C_9_RP_0/results.txt and I change the command as follows: find ./ -name "results.txt" | sort and the output is: ./params_R_11_C_16_RP_0/results.txt ./params_R_11_C_25_RP_0/results.txt ./params_R_11_C_4_RP_0/results.txt ./params_R_11_C_9_RP_0/results.txt ./params_R_5_C_16_RP_0/results.txt ./params_R_5_C_25_RP_0/results.txt ./params_R_5_C_4_RP_0/results.txt ./params_R_5_C_9_RP_0/results.txt ./params_R_7_C_16_RP_0/results.txt ./params_R_7_C_25_RP_0/results.txt ./params_R_7_C_4_RP_0/results.txt ./params_R_7_C_9_RP_0/results.txt ./params_R_9_C_16_RP_0/results.txt ./params_R_9_C_25_RP_0/results.txt ./params_R_9_C_4_RP_0/results.txt ./params_R_9_C_9_RP_0/results.txt But I want it output as following: ./params_R_5_C_4_RP_0/results.txt ./params_R_5_C_9_RP_0/results.txt ./params_R_5_C_16_RP_0/results.txt ./params_R_5_C_25_RP_0/results.txt ./params_R_7_C_4_RP_0/results.txt ./params_R_7_C_9_RP_0/results.txt ./params_R_7_C_16_RP_0/results.txt ./params_R_7_C_25_RP_0/results.txt ./params_R_9_C_4_RP_0/results.txt ./params_R_9_C_9_RP_0/results.txt ./params_R_9_C_16_RP_0/results.txt ./params_R_9_C_25_RP_0/results.txt ... I should let it params_R_005_C_004_RP_0 when generating the results. But it would take much time to rerun the program to get the results. So I wonder if there is any way to use the bash command to achieve this objective.
