• Several xml errors using Facebook JS SDK with xhtml strict

  - by Landitus

  I'm trying to set up some like buttons to a project. These buttons live inside a jquery slideshow with Aino's Galleria and let you "Like" each different slide. I'm using an xHTML strict document and while in Firefox (and Firebug) everything seems ok, but in webkit inspector I get this: XML self-closing tag syntax used on <fb:like>. The tag will not be closed. [The HTML that caused this error was generated by a script.] XML self-closing tag syntax used on <fb:like>. The tag will not be closed. I get one of these every slide, so there are 28 errors. Looking into it, found some seem to enclose the fb:like into something like this: <script type="text/javascript"> //<![CDATA[ document.write('<fb:like href="<?php echo "http://www.site/image-".$image_id ;?>" width="260" height="80" show_faces="false" />'); //]]> </script> The above, still works in Firefox, but not in Safari. The inspector says: 26 XFBML tags failed to render in 30000ms. Moreover, for the Facebook like buttons to work with the Galleria Jquery plugin, I have a custom function that reloads only the facebook like button concerning the actual slide which appears briefly upon loading the slide: [...] extend: function(options) { // listen to when an image is shown this.bind(Galleria.IMAGE, function(e) { number = e.index + 1; tag = $('.galleria-info-description .info-box-'+number).find('.btn_fb'); $(tag).each(function() { FB.XFBML.parse( this ); }); }); } This thing is getting more complex and really don't know who is causing the problem! Hope somebody can help or ask the right questions!

• Django stupid mark_safe?

  - by Mark

  I wrote this little function for writing out HTML tags: def html_tag(tag, content=None, close=True, attrs={}): lst = ['<',tag] for key, val in attrs.iteritems(): lst.append(' %s="%s"' % (key, escape_html(val))) if close: if content is None: lst.append(' />') else: lst.extend(['>', content, '</', tag, '>']) else: lst.append('>') return mark_safe(''.join(lst)) Which worked great, but then I read this article on efficient string concatenation (I know it doesn't really matter for this, but I wanted consistency) and decided to update my script: def html_tag(tag, body=None, close=True, attrs={}): s = StringIO() s.write('<%s'%tag) for key, val in attrs.iteritems(): s.write(' %s="%s"' % (key, escape_html(val))) if close: if body is None: s.write(' />') else: s.write('>%s</%s>' % (body, tag)) else: s.write('>') return mark_safe(s.getvalue()) But now my HTML get escaped when I try to render it from my template. Everything else is exactly the same. It works properly if I replace the last line with return mark_safe(unicode(s.getvalue())). I checked the return type of s.getvalue(). It should be a str, just like the first function, so why is this failing?? Also fails with SafeString(s.getvalue()) but succeeds with SafeUnicode(s.getvalue()). I'd also like to point out that I used return mark_safe(s.getvalue()) in a different function with no odd behavior.

• Downloading jQuery UI: Ok, so what part of this mess do I copy to the server?

  - by Martha

  From the "should be simple, but..." files: Trying to get started with jQuery UI. Went to the site, used their custom builder thingy to assemble the parts I need, made myself a custom theme using the Theme Roller, downloaded the zip file thus produced, unzipped it on my local drive. Ok, so I have 37 folders, 311 files, and a total of 2.4 MB. Ain't no way in hell all this is going on the server. What parts do I need to put there? 'css' 'custom-theme': jquery-ui-1.8.custom.css, 'images' subfolder with 12 .png images 'development-bundle' 'demos': demos.css, index.html, plus 18 subfolders, but I'm guessing "not needed" 'docs': 17 .html files, but again, I'm guessing "not needed" 'external': 4 .js files, one .css 'themes': 'base' and 'custom-theme' subfolders, each with 8 or 9 .css files and an 'images' subfolder with about a dozen images 'ui': 25 .js files, an 'i18n' subfolder with 53 .js files, and a 'minified' subfolder with 24 .js files 'js': jquery-1.4.2.min.js and jquery-ui-1.8.custom.min.js Also, the file structure. Our server is set up something like this: root admin (administrative tools) css forms (the gist of the site lives here) images include (asp code snippets that are used by multiple pages) js (just a few things right now, like an ancient wheezing spelling checker) As far as I can tell, the jQuery css files assume that (1) each theme is in its own folder, and (2) each folder has its own images subfolder. How can I convince it otherwise? i.e. put the necessary .js files in the 'js' folder, the .css files in the 'css' folder, and the images in the 'images' folder?

• random data using php & mysql

  - by Prakash

  I have mysql database structure like below: CREATE TABLE test ( id int(11) NOT NULL auto_increment, title text NULL, tags text NULL, PRIMARY KEY (id) ); data on field tags is stored as a comma separated text like html,php,mysql,website,html etc... now I need create an array that contains around 50 randomly selected tags from random records. currently I am using rand() to select 15 random mysql data from database and then holding all the tags from 15 records in an array. Then I am using array_rand() for randomizing the array and selecting only 50 random records. $query=mysql_query("select * from test order by id asc, RAND() limit 15"); $tags=""; while ($eachData=mysql_fetch_array($query)) { $additionalTags=$eachData['tags']; if ($tags=="") { $tags.=$additionalTags; } else { $tags.=$tags.",".$additionalTags; } } $tags=explode(",", $tags); $newTags=array(); foreach ($tags as $tag) { $tag=trim($tag); if ($tag!="") { if (!in_array($tag, $newTags)) { $newTags[]=$tag; } } } $random_newTags=array_rand($newTags, 50); Now I have huge records on the database, and because of that; rand() is performing very slow and sometimes it doesn't work. So can anyone let me know how to handle this situation correctly so that my page will work normally.

• IMAP protocol support in different email servers

  - by raticulin

  Having to interact with several different email servers via IMAP (using javamail), I have found that there is a very different level of support for IMAP features among them. The lack of support of some features has resulted in more developing time, more complicated code to deal with different support, worse perforamance due to not being able to SEARCH etc. So I would like to get some info on other servers and what level of support they provide. So far I have dealt with Lotus Domino and Novell GroupWise (and to a lesser extend Exchange 2003 and 2007). I am particularly interested in most used one in unix/linux (Courier, Cyrus, Dovecot, UW IMAP) and also Zimbra, but feel free to add any you know. Also welcomed info about online services like gmail. Features that I consider (comment if you are interested in others and I'll add them. Custom flags Searching Custom flags Searching arbitrary headers Partial fetching Proxy authentication And what I have found so far (correct if I am wrong anywhere): Lotus Domino Custom flags yes Searching Custom flags yes Searching arbitrary headers yes Partial fetching ? Proxy authentication sort of, you can give some user permissions to access other users mailboxes and he will see them under his '\Other Users' folder Novell GroupWise Custom flags No Searching Custom flags No Searching arbitrary headers No Partial fetching ? Proxy authentication yes, you can use what is called a Trusted Application

• Inserting an element within jQuery Validation plugin's error template

  - by simshaun

  I'm utilizing the jQuery Validation plugin for my form. It lets you change the errorElement and wrap the errorElement using with the wrapper option. But, I want to insert an element within errorElement like this: <label class="error"><em></em>Error message goes here</label> Is there an easy way to accomplish inserting the em tag? I've tried prepending the em tag using the errorPlacement option (see below), but it seems the plugin is replacing the contents of errorElement afterwards. $.validator.setDefaults({ errorPlacement: function(error, element) { error.prepend('<em/>'); error.insertBefore(element); } }); I've also tried prepending the em tag using the showErrors option (see below). Again, it seems the plugin is replacing the contents of errorElement afterwards. $.validator.setDefaults({ showErrors: function(errorMap, errorList) { for (var i = 0; i < errorList.length; i++) { var error = errorList[i], $label = this.errorsFor(error.element), $element = $(error.element); if ($label.length && $label.find('em').length == 0) { $label.prepend('<em/>'); } } this.defaultShowErrors(); } }); I've also tried modifying the plugin so that when the error element is generated, the <em> tag is prepended. That works until I focus on a form element that has an error, after which the em tag is removed. (It's doing this because jQuery validation is constantly updating the contents of the error element as I focus and/or type in the field, therefore erasing my em tag added at error-element creation.)

• How do you deserialize a collection with child collections?

  - by Stuart Helwig

  I have a collection of custom entity objects one property of which is an ArrayList of byte arrays. The custom entity is serializable and the collection property is marked with the following attributes: [XmlArray("Images"), XmlArrayItem("Image",typeof(byte[]))] So I serialize a collection of these custom entities and pass them to a web service, as a string. The web service receives the string and byte array in tact, The following code then attempts to deserialize the collection - back into custom entities for processing... XmlSerializer ser = new XmlSerializer(typeof(List<myCustomEntity>)); StringReader reader = new StringReader(xmlStringPassedToWS); List<myCustomEntity> entities = (List<myCustomEntity>)ser.Deserialize(reader); foreach (myCustomEntity e in entities) { // ...do some stuff... foreach (myChildCollection c in entities.ChildCollection { // .. do some more stuff.... } } I've checked the XML resulting from the initial serialization and it does contain byte array - the child collection, as does the StringReader built above. After the deserialization process, the resulting collection of custom entites is fine, except that each object in the collection does not contain any items in its child collection. (i.e. it doesn't get to "...do some more stuff..." above. Can someone please explain what I am doing wrong? Is it possible to serialize ArrayLists within a generic collection of custom entities?

• Filtering Questions (posts) by tag_name in TagController#index passing /tags?tag_name=something

  - by bgadoci

  I am trying to get my TagsController#index action to display only the Questions that contain certain tags when passing the search parameter tag_name. I am not getting an error just can't get the filter to work correctly such that upon receiving the /tags?tag_name=something url, only those questions are displayed . Here is the setup: class Tag < ActiveRecord::Base belongs_to :question def self.search(str) return [] if str.blank? cond_text = str.split.map{|w| "tag_name LIKE ? "}.join(" OR ") cond_values = str.split.map{|w| "%#{w}%"} all(:order => "created_at DESC", :conditions => (str ? [cond_text, *cond_values] : [])) end end and class Question < ActiveRecord::Base has_many :tags, :dependent => :destroy end tag link that would send the URL to the TagsController looks like this: <%= link_to(tag_name, tags_path(:tag_name => tag_name)) %> and outputs: /tags?tag_name=something In my /views/tags/index.html.erb view I am calling the questions by rendering a partial /views/questions/_question.html.erb. <%= render :partial => @questions %> When I send the URL with the search parameter nothing happens. Here is my TagsController#index action: def index @tags = Tag.search(params[:search]).paginate :page => params[:page], :per_page => 5 @tagsearch = Tag.search(params[:search]) @tag_counts = Tag.count(:group => :tag_name, :order => 'count_all DESC', :limit => 100) @questions = Question.all( :order => 'created_at DESC', :limit => 50) respond_to do |format| format.html # index.html.erb format.xml { render :xml => @tags } end end How can I properly filter questions displayed in the /views/tags/index.html.erb file for the parameter tag.tag_name?

• SQL trigger to delete rows from database

  - by wpearse

  I have an industrial system that logs alarms to a remotely hosted MySQL database. The industrial system inserts a new row whenever a property of the alarm changes (such as the time the alarm was activated, acknowledged or switched off) into a table named 'alarms'. I don't want multiple records for each alarm, so I have set up two database triggers. The first trigger mirrors each new record to a second table, creating/updating rows as required: CREATE TRIGGER `mirror_alarms` BEFORE INSERT ON `alarms` FOR EACH ROW INSERT INTO `alarm_display` (Tag,...,OffTime) VALUES (new.Tag,...,new.OffTime) ON DUPLICATE KEY UPDATE OnDate=new.OnDate,...,OffTime=new.OffTime The second trigger should execute after the first and (ideally) delete all rows from the alarms table. (I used the Tag property of the alarm because the Tag property never changes, although I suspect I could just use a 'DELETE FROM alarms WHERE 1' statement to the same effect). CREATE TRIGGER `remove_alarms` AFTER INSERT ON `alarms` FOR EACH ROW DELETE FROM alarms WHERE Tag=new.Tag My problem is that the second trigger doesn't appear to run, or if it does, the second trigger doesn't delete any rows from the database. So here's the question: why does my second trigger not do what I expect it to do?

• Improve a regex statement in order to be as efficient as it can be

  - by user551625

  I have a PHP program that, at some point, needs to analyze a big amount of HTML+javascript text to parse info. All I want to parse needs to be in two parts. Seperate all "HTML goups" to parse Parse each HTML group to get the needed information. In the 1st parse it needs to find: <div id="myHome" And start capturing after that tag. Then stop capturing before <span id="nReaders" And capture the number that comes after this tag and stop. In the 2nd parse use the capture nº 1 (0 has the whole thing and 2 has the number) from the parse made before and then find . I already have code to do that and it works. Is there a way to improve this, make it easier for the machine to parse? preg_match_all('%<div id="myHome"[^>]>(.*?)<span id="nReaders[^>]>([0-9]+)<"%msi', $data, $results, PREG_SET_ORDER); foreach($results AS $result){ preg_match_all('%<div class="myplacement".*?[.]php[?]((?:next|before))=([0-9]+).*?<tbody.*?<td[^>]>.*?[0-9]+"%msi', $result[1], $mydata, PREG_SET_ORDER); //takes care of the data and finish the program Note: I need this for a freeware program so it must be as general as possible and, if possible, not use php extensions ADD: I ommitted some parts here because I didn't expect for answers like those. There is also a need to parse text inside one of the tags that is in the document. It may be the 6th 7th or 8th tag but I know it is after a certain tag. The parser I've checked (thx profitphp) does work to find the script tag. What now? There are more than 1 tag with the same class. I want them all. But I want only with also one of a list of classes..... Where can I find instructions and demos and limitations of DOM parsers (like the one in http://simplehtmldom.sourceforge.net/)? I need something that will work on, at least, a big amount of free servers.

• Why doesn't this CompiledQuery give a performance improvement?

  - by Grammarian

  I am trying to speed up an often used query. Using a CompiledQuery seemed to be the answer. But when I tried the compiled version, there was no difference in performance between the compiled and non-compiled versions.

• ASP.NET Web API Exception Handling

  - by Fredrik N

  When I talk about exceptions in my product team I often talk about two kind of exceptions, business and critical exceptions. Business exceptions are exceptions thrown based on “business rules”, for example if you aren’t allowed to do a purchase. Business exceptions in most case aren’t important to log into a log file, they can directly be shown to the user. An example of a business exception could be "DeniedToPurchaseException”, or some validation exceptions such as “FirstNameIsMissingException” etc. Critical Exceptions are all other kind of exceptions such as the SQL server is down etc. Those kind of exception message need to be logged and should not reach the user, because they can contain information that can be harmful if it reach out to wrong kind of users. I often distinguish business exceptions from critical exceptions by creating a base class called BusinessException, then in my error handling code I catch on the type BusinessException and all other exceptions will be handled as critical exceptions. This blog post will be about different ways to handle exceptions and how Business and Critical Exceptions could be handled. Web API and Exceptions the basics When an exception is thrown in a ApiController a response message will be returned with a status code set to 500 and a response formatted by the formatters based on the “Accept” or “Content-Type” HTTP header, for example JSON or XML. Here is an example:   public IEnumerable<string> Get() { throw new ApplicationException("Error!!!!!"); return new string[] { "value1", "value2" }; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The response message will be: HTTP/1.1 500 Internal Server Error Content-Length: 860 Content-Type: application/json; charset=utf-8 { "ExceptionType":"System.ApplicationException","Message":"Error!!!!!","StackTrace":" at ..."} .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   The stack trace will be returned to the client, this is because of making it easier to debug. Be careful so you don’t leak out some sensitive information to the client. So as long as you are developing your API, this is not harmful. In a production environment it can be better to log exceptions and return a user friendly exception instead of the original exception. There is a specific exception shipped with ASP.NET Web API that will not use the formatters based on the “Accept” or “Content-Type” HTTP header, it is the exception is the HttpResponseException class. Here is an example where the HttpReponseExcetpion is used: // GET api/values [ExceptionHandling] public IEnumerable<string> Get() { throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.InternalServerError)); return new string[] { "value1", "value2" }; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The response will not contain any content, only header information and the status code based on the HttpStatusCode passed as an argument to the HttpResponseMessage. Because the HttpResponsException takes a HttpResponseMessage as an argument, we can give the response a content: public IEnumerable<string> Get() { throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.InternalServerError) { Content = new StringContent("My Error Message"), ReasonPhrase = "Critical Exception" }); return new string[] { "value1", "value2" }; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   The code above will have the following response:   HTTP/1.1 500 Critical Exception Content-Length: 5 Content-Type: text/plain; charset=utf-8 My Error Message .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The Content property of the HttpResponseMessage doesn’t need to be just plain text, it can also be other formats, for example JSON, XML etc. By using the HttpResponseException we can for example catch an exception and throw a user friendly exception instead: public IEnumerable<string> Get() { try { DoSomething(); return new string[] { "value1", "value2" }; } catch (Exception e) { throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.InternalServerError) { Content = new StringContent("An error occurred, please try again or contact the administrator."), ReasonPhrase = "Critical Exception" }); } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   Adding a try catch to every ApiController methods will only end in duplication of code, by using a custom ExceptionFilterAttribute or our own custom ApiController base class we can reduce code duplicationof code and also have a more general exception handler for our ApiControllers . By creating a custom ApiController’s and override the ExecuteAsync method, we can add a try catch around the base.ExecuteAsync method, but I prefer to skip the creation of a own custom ApiController, better to use a solution that require few files to be modified. The ExceptionFilterAttribute has a OnException method that we can override and add our exception handling. Here is an example: using System; using System.Diagnostics; using System.Net; using System.Net.Http; using System.Web.Http; using System.Web.Http.Filters; public class ExceptionHandlingAttribute : ExceptionFilterAttribute { public override void OnException(HttpActionExecutedContext context) { if (context.Exception is BusinessException) { throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.InternalServerError) { Content = new StringContent(context.Exception.Message), ReasonPhrase = "Exception" }); } //Log Critical errors Debug.WriteLine(context.Exception); throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.InternalServerError) { Content = new StringContent("An error occurred, please try again or contact the administrator."), ReasonPhrase = "Critical Exception" }); } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   Note: Something to have in mind is that the ExceptionFilterAttribute will be ignored if the ApiController action method throws a HttpResponseException. The code above will always make sure a HttpResponseExceptions will be returned, it will also make sure the critical exceptions will show a more user friendly message. The OnException method can also be used to log exceptions. By using a ExceptionFilterAttribute the Get() method in the previous example can now look like this: public IEnumerable<string> Get() { DoSomething(); return new string[] { "value1", "value2" }; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } To use the an ExceptionFilterAttribute, we can for example add the ExceptionFilterAttribute to our ApiControllers methods or to the ApiController class definition, or register it globally for all ApiControllers. You can read more about is here. Note: If something goes wrong in the ExceptionFilterAttribute and an exception is thrown that is not of type HttpResponseException, a formatted exception will be thrown with stack trace etc to the client. How about using a custom IHttpActionInvoker? We can create our own IHTTPActionInvoker and add Exception handling to the invoker. The IHttpActionInvoker will be used to invoke the ApiController’s ExecuteAsync method. Here is an example where the default IHttpActionInvoker, ApiControllerActionInvoker, is used to add exception handling: public class MyApiControllerActionInvoker : ApiControllerActionInvoker { public override Task<HttpResponseMessage> InvokeActionAsync(HttpActionContext actionContext, System.Threading.CancellationToken cancellationToken) { var result = base.InvokeActionAsync(actionContext, cancellationToken); if (result.Exception != null && result.Exception.GetBaseException() != null) { var baseException = result.Exception.GetBaseException(); if (baseException is BusinessException) { return Task.Run<HttpResponseMessage>(() => new HttpResponseMessage(HttpStatusCode.InternalServerError) { Content = new StringContent(baseException.Message), ReasonPhrase = "Error" }); } else { //Log critical error Debug.WriteLine(baseException); return Task.Run<HttpResponseMessage>(() => new HttpResponseMessage(HttpStatusCode.InternalServerError) { Content = new StringContent(baseException.Message), ReasonPhrase = "Critical Error" }); } } return result; } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } You can register the IHttpActionInvoker with your own IoC to resolve the MyApiContollerActionInvoker, or add it in the Global.asax: GlobalConfiguration.Configuration.Services.Remove(typeof(IHttpActionInvoker), GlobalConfiguration.Configuration.Services.GetActionInvoker()); GlobalConfiguration.Configuration.Services.Add(typeof(IHttpActionInvoker), new MyApiControllerActionInvoker()); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   How about using a Message Handler for Exception Handling? By creating a custom Message Handler, we can handle error after the ApiController and the ExceptionFilterAttribute is invoked and in that way create a global exception handler, BUT, the only thing we can take a look at is the HttpResponseMessage, we can’t add a try catch around the Message Handler’s SendAsync method. The last Message Handler that will be used in the Wep API pipe-line is the HttpControllerDispatcher and this Message Handler is added to the HttpServer in an early stage. The HttpControllerDispatcher will use the IHttpActionInvoker to invoke the ApiController method. The HttpControllerDipatcher has a try catch that will turn ALL exceptions into a HttpResponseMessage, so that is the reason why a try catch around the SendAsync in a custom Message Handler want help us. If we create our own Host for the Wep API we could create our own custom HttpControllerDispatcher and add or exception handler to that class, but that would be little tricky but is possible. We can in a Message Handler take a look at the HttpResponseMessage’s IsSuccessStatusCode property to see if the request has failed and if we throw the HttpResponseException in our ApiControllers, we could use the HttpResponseException and give it a Reason Phrase and use that to identify business exceptions or critical exceptions. I wouldn’t add an exception handler into a Message Handler, instead I should use the ExceptionFilterAttribute and register it globally for all ApiControllers. BUT, now to another interesting issue. What will happen if we have a Message Handler that throws an exception?  Those exceptions will not be catch and handled by the ExceptionFilterAttribute. I found a  bug in my previews blog post about “Log message Request and Response in ASP.NET WebAPI” in the MessageHandler I use to log incoming and outgoing messages. Here is the code from my blog before I fixed the bug:   public abstract class MessageHandler : DelegatingHandler { protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken) { var corrId = string.Format("{0}{1}", DateTime.Now.Ticks, Thread.CurrentThread.ManagedThreadId); var requestInfo = string.Format("{0} {1}", request.Method, request.RequestUri); var requestMessage = await request.Content.ReadAsByteArrayAsync(); await IncommingMessageAsync(corrId, requestInfo, requestMessage); var response = await base.SendAsync(request, cancellationToken); var responseMessage = await response.Content.ReadAsByteArrayAsync(); await OutgoingMessageAsync(corrId, requestInfo, responseMessage); return response; } protected abstract Task IncommingMessageAsync(string correlationId, string requestInfo, byte[] message); protected abstract Task OutgoingMessageAsync(string correlationId, string requestInfo, byte[] message); } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   If a ApiController throws a HttpResponseException, the Content property of the HttpResponseMessage from the SendAsync will be NULL. So a null reference exception is thrown within the MessageHandler. The yellow screen of death will be returned to the client, and the content is HTML and the Http status code is 500. The bug in the MessageHandler was solved by adding a check against the HttpResponseMessage’s IsSuccessStatusCode property: public abstract class MessageHandler : DelegatingHandler { protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken) { var corrId = string.Format("{0}{1}", DateTime.Now.Ticks, Thread.CurrentThread.ManagedThreadId); var requestInfo = string.Format("{0} {1}", request.Method, request.RequestUri); var requestMessage = await request.Content.ReadAsByteArrayAsync(); await IncommingMessageAsync(corrId, requestInfo, requestMessage); var response = await base.SendAsync(request, cancellationToken); byte[] responseMessage; if (response.IsSuccessStatusCode) responseMessage = await response.Content.ReadAsByteArrayAsync(); else responseMessage = Encoding.UTF8.GetBytes(response.ReasonPhrase); await OutgoingMessageAsync(corrId, requestInfo, responseMessage); return response; } protected abstract Task IncommingMessageAsync(string correlationId, string requestInfo, byte[] message); protected abstract Task OutgoingMessageAsync(string correlationId, string requestInfo, byte[] message); } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } If we don’t handle the exceptions that can occur in a custom Message Handler, we can have a hard time to find the problem causing the exception. The savior in this case is the Global.asax’s Application_Error: protected void Application_Error() { var exception = Server.GetLastError(); Debug.WriteLine(exception); } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } I would recommend you to add the Application_Error to the Global.asax and log all exceptions to make sure all kind of exception is handled. Summary There are different ways we could add Exception Handling to the Wep API, we can use a custom ApiController, ExceptionFilterAttribute, IHttpActionInvoker or Message Handler. The ExceptionFilterAttribute would be a good place to add a global exception handling, require very few modification, just register it globally for all ApiControllers, even the IHttpActionInvoker can be used to minimize the modifications of files. Adding the Application_Error to the global.asax is a good way to catch all unhandled exception that can occur, for example exception thrown in a Message Handler.   If you want to know when I have posted a blog post, you can follow me on twitter @fredrikn

• Installed Ubuntu 14.04LTS

  - by user291729

  On my laptop which came pre-installed with Windows 8.1. Felt I needed to see the competition for myself to establish which was a better OS. So I followed the channels to dual boot. All seemed fine and I accessed Ubuntu with no issues after selecting this from the menu to select the OS. I should add that the boot method was changed to legacy. However, since using Ubuntu, I no longer have the ability to select the OS. The laptop simply logs straight into Ubuntu. I therefore attempted to access the recovery options, only it appears the Windows 8 bootloader has somehow been corrupted as I am now told to use the Windows 8 recovery disc (which, as this was pre-installed - I do not have). Left with no other alternative, I have scoured these forums without success, and so I am hoping someone in the know (or who has experienced similar) can help. I have tried boot repair again without success. On rebooting I am only presented with a basic splash screen asking me to select Ubuntu, Memtest, Windows 8 Recovery or Windows 8 Bootloader (The bootloaders again require I insert the disc). I have tried Code: cat /boot/grub/grub.cfg df -h sudo fdisk -l cat /proc/partitions # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ];

However, if I'm to try using Ubuntu again then there is the risk this problem may come back. Again, I did not do anything manually - the installer did everything (with the exception of changing the boot to Legacy to allow the booting of another bootloader). LiveCD works but doesn't give me the options that I've seen here and as mentioned earlier, only boot recovery only gives me the options as mentioned earlier. Also this fails to load via USB (possibly because HDD comes before USB in the boot order?). Being used to a Windows environment, the Ubuntu (and Linux) environment is a dive at a less than comfortable depth at present (but one I fully intend to get to grips with - especially the commands being more common via Terminal). I very much appreciate the help with this guys.

• Advice on designing a robust program to handle a large library of meta-information & programs

  - by Sam Bryant

  So this might be overly vague, but here it is anyway I'm not really looking for a specific answer, but rather general design principles or direction towards resources that deal with problems like this. It's one of my first large-scale applications, and I would like to do it right. Brief Explanation My basic problem is that I have to write an application that handles a large library of meta-data, can easily modify the meta-data on-the-fly, is robust with respect to crashing, and is very efficient. (Sorta like the design parameters of iTunes, although sometimes iTunes performs more poorly than I would like). If you don't want to read the details, you can skip the rest Long Explanation Specifically I am writing a program that creates a library of image files and meta-data about these files. There is a list of tags that may or may not apply to each image. The program needs to be able to add new images, new tags, assign tags to images, and detect duplicate images, all while operating. The program contains an image Viewer which has tagging operations. The idea is that if a given image A is viewed while the library has tags T1, T2, and T3, then that image will have boolean flags for each of those tags (depending on whether the user tagged that image while it was open in the Viewer). However, prior to being viewed in the Viewer, image A would have no value for tags T1, T2, and T3. Instead it would have a "dirty" flag indicating that it is unknown whether or not A has these tags or not. The program can introduce new tags at any time (which would automatically set all images to "dirty" with respect to this new tag) This program must be fast. It must be easily able to pull up a list of images with or without a certain tag as well as images which are "dirty" with respect to a tag. It has to be crash-safe, in that if it suddenly crashes, all of the tagging information done in that session is not lost (though perhaps it's okay to loose some of it) Finally, it has to work with a lot of images (10,000) I am a fairly experienced programmer, but I have never tried to write a program with such demanding needs and I have never worked with databases. With respect to the meta-data storage, there seem to be a few design choices: Choice 1: Invidual meta-data vs centralized meta-data Individual Meta-Data: have a separate meta-data file for each image. This way, as soon as you change the meta-data for an image, it can be written to the hard disk, without having to rewrite the information for all of the other images. Centralized Meta-Data: Have a single file to hold the meta-data for every file. This would probably require meta-data writes in intervals as opposed to after every change. The benefit here is that you could keep a centralized list of all images with a given tag, ect, making the task of pulling up all images with a given tag very efficient

• How To: Spell Check InfoPath web form in SharePoint 2010

  - by Jeremy Ramos

  Originally posted on: http://geekswithblogs.net/JeremyRamos/archive/2013/11/07/how-to-spell-check-infopath-web-form-in-sharepoint-2010.aspxThis is a sequel to my 2011 post about How To: Spell Check InfoPath Web Form in SharePoint. This time I will share how I managed to achieve Spell Checking in SharePoint 2010. This time round, we have changed our Online Forms strategy to use Custom lists instead of Form Libraries. I thought everything will be smooth sailing as we are using all OOTB features. So, we customised a Custom list form using InfoPath and added a few Rich Text Boxes (Spell Check is a requirement for this specific project). All is good in the InfoPath client including the Spell Checker so, happy days, I published straight away.Here comes the surprises now. I browsed to my Custom List and clicked Add New Item. This launched my Form in a modal dialog format. I went to my Rich Text Boxes to check the spell checker, and voila, it's disabled!I tried hacking the FormServer.aspx and the CustomSpellCheckEntirePage.js again but the new FormServer.aspx behaves differently than of MOSS 2007's. I searched for answers in many blogs to no avail. Often ending up being linked to my old blog post. I also tried placing the spell check javascript into a Content Editor Webpart of the Item's New Form and Edit form. It is launching the Spell Check dialog but it's not spellchecking the page correctly.At this point, I decided I needed to get my project across ASAP so enough with experimentations and logged a ticket with Microsoft Premier Support.On a call with the Support Engineer, I browsed through the Custom List and to the item to demonstrate my problem. Suddenly, the Spell Check tab in the toolbar is now Enabled! Surprised? Not much, it's Microsoft!Anyway, to cut my story short, here is a summary of my solution:Navigate to your Custom ListIn the Ribbon Toolbar, navigate to List > Customize List > Form Web Parts > Content Type Forms > (Item) New Form. This will display the newifs.aspx which is the page displayed when Add New Item is clicked. This page, just like any other SharePoint page, contains webparts. In this case, we have the InfoPath Form Web Part.Add a Content Editor Web Part (CEWP) on top of the InfoPath Form Web Part. (A blank CEWP would do for this example)Navigate to Page and click Stop EditingClick Add New Item again and navigate to a Rich Text box. Tadah! The Spell Check tab is now enabled!Do the same steps for the (Item) Edit Form to enable Spell Checks when editing an item.This "no code" solution discovered purely by accident!

• Some More New ADF Features in JDeveloper 11.1.2

  - by Steven Davelaar

  The official list of new features in JDeveloper 11.1.2 is documented here. While playing with JDeveloper 11.1.2 and scanning the web user interface developer's guide for 11.1.2, I noticed some additional new features in ADF Faces, small but might come in handy:  You can use the af:formatString and af:formatNamed constructs in EL expressions to use substituation variables. For example: <af:outputText value="#{af:formatString('The current user is: {0}',someBean.currentUser)}"/> See section 3.5.2 in web user interface guide for more info. A new ADF Faces Client Behavior tag: af:checkUncommittedDataBehavior. See section 20.3 in web user interface guide for more info. For this tag to work, you also need to set the  uncommittedDataWarning  property on the af:document tag. And this property has quite some issues as you can read here. I did a quick test, the alert is shown for a button that is on the same page, however, if you have a menu in a shell page with dynamic regions, then clicking on another menu item does not raise the alert if you have pending changes in the currently displayed region. For now, the JHeadstart implementation of pending changes still seems the best choice (will blog about that soon). New properties on the af:document tag: smallIconSource creates a so-called favicon that is displayed in front of the URL in the browser address bar. The largeIconSource property specifies the icon used by a mobile device when bookmarking the page to the home page. See section 9.2.5 in web user interface guide for more info. Also notice the failedConnectionText property which I didn't know but was already available in JDeveloper 11.1.1.4. The af:showDetail tag has a new property handleDisclosure which you can set to client for faster rendering. In JDeveloper 11.1.1.x, an expression like #{bindings.JobId.inputValue} would return the internal list index number when JobId was a list binding. To get the actual JobId attribute value, you needed to use #{bindings.JobId.attributeValue}. In JDeveloper 11.1.2 this is no longer needed, the #{bindings.JobId.inputValue} expression will return the attribute value corresponding with the selected index in the choice list. Did you discover other "hidden" new features? Please add them as comment to this blog post so everybody can benefit.

• Creating a Yes/No MessageBox in a NuGet install/uninstall script

  - by ParadigmShift

  Sometimes getting a little feedback during the install/uninstall process of a NuGet package could be really useful. Instead of accounting for all possible ways to install your NuGet package for every user, you can simplify the installation by clarifying with the user what they want. This example shows how to generate a windows yes/no message box to get input from the user in the PowerShell install or uninstall script. We’ll use the prompt on the uninstall to confirm if the user wants to delete a custom setting that the initial install placed in their configuration.  Obviously you could use the prompt in any way you want. The objects of the message box are generated similar to the controls in the code behind of a WinForm. At the beginning of your script enter this: param($installPath, $toolsPath, $package, $project)   # Set up path variables $solutionDir = Get-SolutionDir $projectName = (Get-Project).ProjectName $projectPath = Join-Path $solutionDir $projectName   ################################################################################################ # WinForm generation for prompt ################################################################################################ function Ask-Delete-Custom-Settings { [void][reflection.assembly]::loadwithpartialname("System.Windows.Forms") [Void][reflection.assembly]::loadwithpartialname("System.Drawing")   $title = "Package Uninstall" $message = "Delete the customized settings?" #Create form and controls $form1 = New-Object System.Windows.Forms.Form $label1 = New-Object System.Windows.Forms.Label $btnYes = New-Object System.Windows.Forms.Button $btnNo = New-Object System.Windows.Forms.Button   #Set properties of controls and form ############ # label1 # ############ $label1.Location = New-Object System.Drawing.Point(12,9) $label1.Name = "label1" $label1.Size = New-Object System.Drawing.Size(254,17) $label1.TabIndex = 0 $label1.Text = $message   ############# # btnYes # ############# $btnYes.Location = New-Object System.Drawing.Point(156,45) $btnYes.Name = "btnYes" $btnYes.Size = New-Object System.Drawing.Size(48,25) $btnYes.TabIndex = 1 $btnYes.Text = "Yes"   ########### # btnNo # ########### $btnNo.Location = New-Object System.Drawing.Point(210,45) $btnNo.Name = "btnNo" $btnNo.Size = New-Object System.Drawing.Size(48,25) $btnNo.TabIndex = 2 $btnNo.Text = "No"   ########### # form1 # ########### $form1.ClientSize = New-Object System.Drawing.Size(281,86) $form1.Controls.Add($label1) $form1.Controls.Add($btnYes) $form1.Controls.Add($btnNo) $form1.Name = "Form1" $form1.Text = $title #Event Handler $btnYes.add_Click({btnYes_Click}) $btnNo.add_Click({btnNo_Click}) return $form1.ShowDialog() } function btnYes_Click { #6 = Yes $form1.DialogResult = 6 } function btnNo_Click { #7 = No $form1.DialogResult = 7 } ################################################################################################ This has also wired up the click events to the form.  This is all it takes to create the message box. Now we have to actually use the message box and get the user’s response or this is all pointless.  We’ll then delete the section of the application/web configuration called <Custom.Settings> [xml] $configXmlContent = Get-Content $configFile   Write-Host "Please respond to the question in the Dialog Box." $dialogResult = Ask-Delete-Custom-Settings #6 = Yes #7 = No Write-Host "dialogResult = $dialogResult" if ($dialogResult.ToString() -eq "Yes") { Write-Host "Deleting customized settings" $customSettingsNode = $configXmlContent.configuration.Item("Custom.Settings") $configXmlContent.configuration.RemoveChild($customSettingsNode) $configXmlContent.Save($configFile) } if ($dialogResult.ToString() -eq "No") { Write-Host "Do not delete customized settings" } The part where I check if ($dialog.Result.ToString() –eq “Yes”) could just as easily check the value for either 6 or 7 (Yes or No).  I just personally decided I liked this way better.   Shahzad Qureshi is a Software Engineer and Consultant in Salt Lake City, Utah, USA His certifications include: Microsoft Certified System Engineer 3CX Certified Partner Global Information Assurance Certification – Secure Software Programmer – .NET He is the owner of Utah VoIP Store at http://www.utahvoipstore.com/ and SWS Development at http://www.swsdev.com/ and publishes windows apps under the name Blue Voice.

• How do I create weapon attachments?

  - by Tron86

  My question is; I am developing a game for XNA and I am trying to create a weapon attachment for my player model. My player model loads the .md3 format and reads tags for attachment points. I am able to get the tag of my model's hand. And I am also able to get the tag of my weapon's handle. Each tag I am able to get the rotation and position of and this is how I am calculating it: Model.worldMatrix = Matrix.CreateScale(Model.scale) * Matrix.CreateRotationX(-MathHelper.PiOver2) * Matrix.CreateRotationY(MathHelper.PiOver2); Pretty simple, the player model has a scale and its orientation(it loads on its side so I just use a 90 degree X axis rotation, and a Y axis rotation to face away from the camera). I then calculate the torso tag on the lower body, which gives me a local coordinate at the waist. Then I take that matrix and calculate the tag_weapon in the upper body. This gives me the hand position in local space. I also get the rotation matrix from that tag that I store for later use. All this seems to work fine. Now I move onto my weapon: Matrix weaponWorld = Matrix.CreateScale(CurrentWeapon.scale) * Matrix.CreateRotationX(-MathHelper.PiOver2) * TagRotationMatrix * Matrix.CreateTranslation(HandTag.Position) * Matrix.CreateRotationY(PlayerRotation) * Matrix.CreateTranslation(CollisionBody.Position) * You may notice the weapon matrix gets rotated by 90 degress on the X axis as well. This is because they load in on their sides. Once again this seems pretty simple and follows the SRT order I keep reading about. My TagRotation matrix is the hand's rotation. HandTag.Position is its position in local space. CreateRotationY(PlayerRotation) is the player's rotation in world space, and the CollisionBody.Position is the player's world location. Everything seems to be in order, and almost works in game. However when the gun spawns and follows the player's hand it seems to be flipped on an axis every couple frames. Almost like the X or Y axis is being inversed then put right back. Its hard to explain and I am totally stumped. Even removing all my X axis fixes does nothing to solve the problem. Hopefully I explained everything enough as I am a bit new to this! Thanks!

• Android: How to bind spinner to custom object list?

  - by niko

  Hi, In the user interface there has to be a spinner which contains some names (the names are visible) and each name has its own ID (the IDs are not equal to display sequence). When the user selects the name from the list the variable currentID has to be changed. The application contains the ArrayList Where User is an object with ID and name: public class User{ public int ID; public String name; } What I don't know is how to create a spinner which displays the list of user's names and bind spinner items to IDs so when the spinner item is selected/changed the variable currentID is set to appropriate value. I would appreciate if anyone could show the solution of the described problem or provide any link useful to solve the problem. Thanks!

• Using DisplayTag library, I want to have the currently selected row have a unique custom class using

  - by Mary

  I have been trying to figure out how to highlight the selected row in a table. In my jsp I have jsp scriplet that can get access to the id of the row the displaytag library is creating. I want to compare it to the the id of the current row selected by the user ${currentNoteId}. Right now if the row id = 849 (hardcoded) the class "currentClass" is added to just that row of the table. I need to change the 849 for the {$currentNoteId} and I don't know how to do it. I am using java, Spring MVC. The jsp: ... <% request.setAttribute("dyndecorator", new org.displaytag.decorator.TableDecorator() { public String addRowClass() { edu.ilstu.ais.advisorApps.business.Note row = (edu.ilstu.ais.advisorApps.business.Note)getCurrentRowObject(); String rowId = row.getId(); if ( rowId.equals("849") ) { return "currentClass"; } return null; } }); %> <c:set var="currentNoteId" value="${studentNotes.currentNote.id}"/> ... <display:table id="noteTable" name="${ studentNotes.studentList }" pagesize="20" requestURI="notesView.form.html" decorator="dyndecorator"> <display:column title="Select" class="yui-button-match" href="/notesView.form.html" paramId="note.id" paramProperty="id"> <input type="button" class="yui-button-match2" name="select" value="Select"/> </display:column> <display:column property="userName" title="Created By" sortable="true"/> <display:column property="createDate" title="Created On" sortable="true" format="{0,date,MM/dd/yy hh:mm:ss a}"/> <display:column property="detail" title="Detail" sortable="true"/> </display:table> ... This could also get done using javascript and that might be best, but the documentation suggested this so I thought I would try it. I cannot find an example anywhere using the addRowClass() unless the comparison is to a field already in the row (a dollar amount is used in the documentation example) or hardcoded in like the "849" id. Thanks for any help you can provide.

• Making an asynchronous Client with boost::asio

  Hello, i'm trying to make an asynchronous Client with boost::asio, i use the daytime asynchronous Server(in the tutorial). However sometimes the Client don't receive the Message, sometimes it do :O I'm sorry if this is too much Code, but i don't know what's wrong :/ Client: #include <iostream> #include <stdio.h> #include <ostream> #include <boost/thread.hpp> #include <boost/bind.hpp> #include <boost/array.hpp> #include <boost/asio.hpp> using namespace std; using boost::asio::ip::tcp; class TCPClient { public: TCPClient(boost::asio::io_service& IO_Service, tcp::resolver::iterator EndPointIter); void Write(); void Close(); private: boost::asio::io_service& m_IOService; tcp::socket m_Socket; boost::array<char, 128> m_Buffer; size_t m_BufLen; private: void OnConnect(const boost::system::error_code& ErrorCode, tcp::resolver::iterator EndPointIter); void OnReceive(const boost::system::error_code& ErrorCode); void DoClose(); }; TCPClient::TCPClient(boost::asio::io_service& IO_Service, tcp::resolver::iterator EndPointIter) : m_IOService(IO_Service), m_Socket(IO_Service) { tcp::endpoint EndPoint = *EndPointIter; m_Socket.async_connect(EndPoint, boost::bind(&TCPClient::OnConnect, this, boost::asio::placeholders::error, ++EndPointIter)); } void TCPClient::Close() { m_IOService.post( boost::bind(&TCPClient::DoClose, this)); } void TCPClient::OnConnect(const boost::system::error_code& ErrorCode, tcp::resolver::iterator EndPointIter) { if (ErrorCode == 0) // Successful connected { m_Socket.async_receive(boost::asio::buffer(m_Buffer.data(), m_BufLen), boost::bind(&TCPClient::OnReceive, this, boost::asio::placeholders::error)); } else if (EndPointIter != tcp::resolver::iterator()) { m_Socket.close(); tcp::endpoint EndPoint = *EndPointIter; m_Socket.async_connect(EndPoint, boost::bind(&TCPClient::OnConnect, this, boost::asio::placeholders::error, ++EndPointIter)); } } void TCPClient::OnReceive(const boost::system::error_code& ErrorCode) { if (ErrorCode == 0) { std::cout << m_Buffer.data() << std::endl; m_Socket.async_receive(boost::asio::buffer(m_Buffer.data(), m_BufLen), boost::bind(&TCPClient::OnReceive, this, boost::asio::placeholders::error)); } else { DoClose(); } } void TCPClient::DoClose() { m_Socket.close(); } int main() { try { boost::asio::io_service IO_Service; tcp::resolver Resolver(IO_Service); tcp::resolver::query Query("127.0.0.1", "daytime"); tcp::resolver::iterator EndPointIterator = Resolver.resolve(Query); TCPClient Client(IO_Service, EndPointIterator); boost::thread ClientThread( boost::bind(&boost::asio::io_service::run, &IO_Service)); std::cout << "Client started." << std::endl; std::string Input; while (Input != "exit") { std::cin >> Input; } Client.Close(); ClientThread.join(); } catch (std::exception& e) { std::cerr << e.what() << std::endl; } } Server: http://www.boost.org/doc/libs/1_39_0/doc/html/boost_asio/tutorial/tutdaytime3/src.html Regards :)
