• Why can I not register a PropertyEditor for String in Spring MVC?

  - by Tom Tucker

  I'm using Spring 3.0.3. I've enabled the default ConversionService by adding this line to my Spring configuration XML. <mvc:annotation-driven/> I'm also using custom PropertyEditor's for certain data types, so I've registered them for corresponding data types like the following and they work fine. webDataBinder.registerCustomEditor(Date.class, new MyPropertyEditor()); I have a custom tag library that extends Spring's Form tag library, and I can acess these PropertyEditor's through getPropertyEditor() of AbstractDataBoundFormElementTag. What I don't understand is that I can't register a custom PropertyEditor for String for some reason. The following wouldn't work. webDataBinder.registerCustomEditor(String.class, new MyPropertyEditor()); When I do getPropertyEditor(), it always returns a ConvertingPropertyEditorAdapter, instead of MyPropertyEditor. Is this a bug? EDIT: I realized that I didn't do some stuff right. Spring works just fine.

• C#: Windows Forms: Getting keystrokes in a panel/picturebox?

  - by Rosarch

  I'm making a level editor for a game using windows forms. The form has several drop down menus, text boxes, etc, where the user can type information. I want to make commands like CTRL + V or CTRL + A available for working within the game world itself, not text manipulation. The game world is represented by a PictureBox contained in a Panel. This event handler isn't ever firing: private System.Windows.Forms.Panel canvas; // ... this.canvas = new System.Windows.Forms.Panel(); // ... this.canvas.PreviewKeyDown += new System.Windows.Forms.PreviewKeyDownEventHandler(this.canvas_PreviewKeyDown); What is the preferred way of doing this? Can a panel even receive keyboard input? I would like to allow the user to use copy/paste/select-all commands when working with the text input, but not when placing objects in the game world.

• How to persist a very abstract data type between sessions: PHP

  - by Greelmo

  I have an abstract data type that behaves much like stack. It represents a history of "graph objects" made by a particular user. Each "graph object" holds one or more "lines", a date range, keys, and a title. Each "line" holds a sql generator configured for a particular subset of data in my db. I would like for these "histories" to be available to users between their sessions. It will be in the form of a tab that reads something like "most recent graphs". What do you believe to be the best way to persist this type of data between sessions. This application could get rather large, so efficiency is a concern. Thanks in advance.

I am trying to get around, to form a to do a search and extract operation. I dont know, how to do it, would like to have some idea. Thanks Soham

• What is the best way to read the uploaded files from Request.Files, StreamReader or BinaryReader or

  - by ramesh.nagul

  I have a form where the user can upload multiple files. I am using MVC 2.0 and in my controller I need to call a webservice that is a common import interface requires the files to passed in as byte[]. .NET exposes Request.Files as a HttpFileCollectionBase and I access the filehandle using HttpPostedFile or HttpPostedFileBase that provides access to the Stream member. What is the best way for me to read the bytes from the stream? BinaryReader? StreamReader? BufferedStream?

• Is JAX-RS suitable as a MVC framework?

  - by deamon

  JAX-RS has some MVC support, but I wonder if JAX-RS is really a good choice to build web application for human use. If a user enters wrong or incomplete information in a form, it should be displayed again like with Grails or Wicket. Is there a comfortable way to do this with JAX-RS? As far as I know the URI mapping doesn't work correctly, if not all required parameters are given or there are type conversion problems (with Date for example). Is that correct? Is there support for internationalized templates?

• [JS] XMLHttpRequest problem

  - by mcco

  I am trying to do "POST" with XMLHttpRequest in a firefox extension, and after that I try to get the "Location" header and open it in a new tab. For some reason, the XMLHttpRequest doesn't contain a location header. My code function web(url,request) { var http = new XMLHttpRequest(); http.open('POST',url,true); http.setRequestHeader('Content-Type','application/x-www-form-urlencoded'); http.onreadystatechange=function() { if(http.readyState == 2) { alert(http.getResponseHeader("Location")); } } http.send(request); } Also, if I change the alert to getAllResponseHeaders() to see all headers, I just don't see the location header there. If I try to spy on the request of the original site with Firebug, it does show me the location header in the response. Please help me resolve my issues. Thanks :) P.S. I'm also unable to open a link in new tab using window.open(url, this.window.title);, but as that's not directly related to the rest of this I'll post a separate question to ask about it.

• Java add leading zeros to a number....

  - by user69514

  I need to return a string in the form xxx-xxxx where xxx is a number and xxxx is another number, however when i have leading zeros they disappear. I'm trying number formatter, but it's not working. public String toString(){ NumberFormat nf3 = new DecimalFormat("#000"); NumberFormat nf4 = new DecimalFormat("#0000"); if( areaCode != 0) return nf3.format(areaCode) + "-" + nf3.format(exchangeCode) + "-" + nf4.format(number); else return exchangeCode + "-" + number; } } I figured it out: public String toString(){ NumberFormat nf3 = new DecimalFormat("000"); NumberFormat nf4 = new DecimalFormat("0000"); if( areaCode != 0) //myFormat.format(new Integer(someValue)); return nf3.format(new Integer(areaCode)) + "-" + nf3.format(new Integer(exchangeCode)) + "-" + nf4.format(new Integer(number)); else return nf3.format(new Integer(exchangeCode)) + "-" + nf4.format(new Integer(number)); }

• Windows Azure: need to know the data processing time

  - by veda

  I have stored some files in the form of blobs on azure and I have written an application that would access these blobs. When I host this application as a web role on azure, it works perfectly and I am happy with that. But now, I wanted to know “what is the query time taken to access each blob file?” I was searching for this through the Microsoft Azure Storage SLA and I found that for GetBlob request type, the maximum processing time should be within the product of 2 seconds multiplied by the number of MBs transferred in processing the request. I am still unclear. What is the actual processing time of my data query? How can I measure it? Can I be able to speed up the processing time? I can understand that the processing time depends on internet speed, location of the data center where my data is being stored, and location of data center where my application is being hosted. But still, will I be able to speed up my query?

• Visual Studio 2008 freezing when editing aspx/master pages

  - by jayrdub

  Visual Studio freezes up continually when I'm editing master pages or aspx files. Here's what I've tried that have not helped: restarting VS only working with few files open at a time Disabled all addins (resharper etc.) deleted .suo and .user files changed default editor from Web Form Editor and Master Page Editor to HTML Editor installed SP1 I don't have tons of files - 3 Master pages and maybe 30 aspx files. It is a asp.net mvc project. All I have to do to get VS to freeze is type a little text or even just paste. The freezing lasts a good 5-10 seconds. My machine has 4GB of RAM and fast disks. Could it have anything to do with asp.net mvc? Would the amount and size of other projects in the solution affect the editor?

• routing problem in codeigniter

  - by Obay

  I'm new to CodeIgniter and routing. I have a Login controller whose index() loads up a view to enter a username/password. In the view, the form has action="login/authenticate". Login-authenticate() determines if the login is valid or not. If it's valid, redirect('lobby'), if not redirect('login') routes.php: $route['default_controller'] = "login" config.php: $config['base_url'] = "http://localhost/dts/"; $config['index_page'] = "index.php"; The problem is that when i go to http://localhost/dts/ , click login, I am correctly (?) redirected to http://localhost/dts/login/authenticate but the browser says Object not found!. But when I go to http://localhost/dts/index.php/ (with trailing slash), it works correctly (I get redirected to http://localhost/dts/index.php/login/authenticate, and am logged in) I tried removing "index.php" by using a .htaccess: RewriteEngine on RewriteCond $1 !^(index\.php|images|robots\.txt) RewriteRule ^(.*)$ /index.php/$1 [L] and it would no longer open even the http://localhost/dts/ I'm confused.. what's going on?

• Generic Text Only printer driver mangles control codes

  - by Terry

  If an escape character (or most other characters < 0x20) is sent to the generic / text only printer it gets printed as a period. Using the code in the WinDDK is it possible to 'correct' this behaviour so that it passes it through unmodified? The general scenario for this is that some application ('user app') outputs a document to a windows printer. My application requires this data in plain text form and so what I do is run a generic / text only printer that talks to a virtual com port. This generally works fine except where the 'user app' outputs binary data to the print queue without using the correct mechanism (which seems to work fine on some printer drivers, such as the Epson POS ones, but not the generic / text only one). I've tried changing the print processor selection without success and also tried looking at the gtt files to see if I could readily map in these characters as though they were printable, but the minidriver tool won't let me do that. Any suggestions?

• Can I use XText for a DSL involving an XML file type?

  - by Chris

  I have defined a small DSL that is mostly written in the form of different types of XML files in conjuction with some property files. This works very well but I wish to create an Eclipse Editor to make editing these files easier for beginners (I already have a working parser). The main XML file can reference some items from the .properties files and vice-versa. THe main xml file can also reference other XML files. Certain options should only be available in the main xml file based on the contents of the .properties files and based on some osgi plugins that can be added to the DSL project (the syntax is dynamic depending on context). The structure of the language is fixed but the options available in each attribute or the choice of attributes themselves changes depending on metadata contained in plugin .jar files. Questions: Does XText support dynamic syntax (validation changes depending on external factors)? Does XText support XML files / .properties files? Thank you very much for your help in advance.

• How to use ORDER BY, LOWER .. in SQL SERVER 2008 with non-unicode data

  - by hgulyan

  Hi, The question is about Armenian. I'm using sql server 2005, collation SQL_Latin1_General_CP1_CI_AS, data mostly is in Armenian and we can't use unicode. I tested on ms sql 2008 with a windows collation for armenian language ( Cyrillic_General_100_ ), I have found here, ( http://msdn.microsoft.com/en-us/library/ms188046.aspx ) but it didn't help. I have a function, that orders hex values and a lower function, which takes each char in each string and converts it to it's lower form, but it's not acceptable solution, it works really slow, calling that functions on every column of a huge table. Is there any solution for this issue not using unicode and not working with hex values manually?

• Prevent password leakage while using sql* loader

  - by Jai

  I have shell script calling Sql*loader utility which inturn uses username/password as arguments. This details cannot be stored on server in any form due to security related policies. i got 2 approaches to handle this situation, 1. create hidden parameter file with login details and limit the access to owner. again the implication is i cannot store login data in any format on server 2. Create the user as OS authenticated and straight away login into sql without any userid/password I am not able to figure out risks involved in 2nd approach which u experienced folks could have come across. let me know if there is any other approach to handle password leakage issue

• Computer Vision application(+web interface) for face detection and recognition from database

  - by Kush

  My project is a computer vision java application which should implement the following : A web interface through which the form entry+images(for example a student data) will be stored into a database(Mysql) & images into directory common to my java application. Then the data & images can be retrieved from my java Gui application and I can perform the following operations of image processing through OpenCV. Actually,I want to run the face detection on images retrieved and discard the false entries(no proper face). Also the application user/admin can search an image based on text search(By Id) or By another reference image using face recognition. I am well familiar with Java but the problem is that I need a guidance on how to organise it in a stepwise manner(links appreciated).OpenCv,Php and mySql are really messy.I know doing the openCV stuff within java is real overhead but i really want to do it.But If there is any suggestion to do it elseway please guide me.So any kind of help is a ray of hope for me. Thanks.

• HTTP Digest Authentication Fails With URL Parameters (CakePHP)

  - by NathanGaskin

  I have a RESTful API set up and working with CakePHP using mapResources() and parseExtensions(). Authentication is handled by CakePHP's security component using HTTP Digest Authentication. Everything works fine, unless I add parameters to the url, in the form: http://example.com/locations.xml?distance=4 Which causes the authentication to always fail. Any ideas? Edit: This seems to be an issue with the regex in parseDigestAuthData(). There's a semi-fix here: http://old.nabble.com/paginator-conflicts-with-Security-%3ErequireLogin---td16301573.html which now allows me to use the format: http://example.com/locations/index/distance:4/.xml But that's not RESTful and doesn't look all that pretty. Still, getting closer!

• NSXMLParser rss issue NSXMLParserInvalidCharacterError

  - by Chris Van Buskirk

  NSXMLParserInvalidCharacterError # 9 This is the error I get when I hit a weird character (like quotes copied and pasted from word to the web form, that end up in the feed). The feed I am using is not giving an encoding, and their is no hope for me to get them to change that. This is all I get in the header: < ?xml version="1.0"? < rss version="2.0" What can I do about illegal characters when parsing feeds? Do I sweep the data prior to the parse? Is there something I am missing in the API? Has anyone dealt with this issue?

• How does Hadoop perform input splits?

  - by Deepak Konidena

  Hi, This is a conceptual question involving Hadoop/HDFS. Lets say you have a file containing 1 billion lines. And for the sake of simplicity, lets consider that each line is of the form <k,v> where k is the offset of the line from the beginning and value is the content of the line. Now, when we say that we want to run N map tasks, does the framework split the input file into N splits and run each map task on that split? or do we have to write a partitioning function that does the N splits and run each map task on the split generated? All i want to know is, whether the splits are done internally or do we have to split the data manually? More specifically, each time the map() function is called what are its Key key and Value val parameters? Thanks, Deepak

• Simple PHP Regex question

  - by Dave Kiss

  Hi all, I'd like to validate a field in a form to make sure it contains the proper formatting for a URL linking to a Vimeo video. Below is what I have in Javascript, but I need to convert this over to PHP (not my forte) Basically, I need to check the field and if it is incorrectly formatted, I need to store an error message as a variable.. if it is correct, i store the variable empty. // Parse the URL var PreviewID = jQuery("#customfields-tf-1-tf").val().match(/http:\/\/(www.vimeo|vimeo)\.com(\/|\/clip:)(\d+)(.*?)/); if ( !PreviewID ) { jQuery("#cleaner").html('<div id="vvqvideopreview"><?php echo $this->js_escape( __("Unable to parse preview URL. Please make sure it's the <strong>full</strong> URL and a valid one at that.", 'vipers-video-quicktags') ); ?></div>'); return; } The traditional vimeo url looks like this: http://www.vimeo.com/10793773 Thanks!
