  • Superfish: How to keep sub menu open after it has been clicked

    - by Roland
    I'm having the following scenario. I have a menu and if one hovers over the menu a sub menu appears and if mouse moves out the sub menu disappears, now I want the following if I click on the on a item in the sub menu, I want the sub-menu to remain open, when the new page has been loaded. I'm using superfish Jquery plugin for this. Is this possible and if how. my code in html <div id="nav"> <div id="nav2"> <ul class="sf-menu sf-navbar "> <li> <a title="HOME" class="sf-with-ul " href="/index.php?r=site/index&amp;sid=1">HOME</a> </li> </ul> <ul class="sf-menu sf-navbar"> <li> <a href="?sid=2" id="gallery" class="sf-with-ul selected_main">GALLERY</a> <ul class="subs" id="sub1"><li class="arrow"><img src="images/arrow.gif" /></li><li><a title="Kitchens" href="/index.php?r=images/sddsd&amp;id=1">Kitchens</a></li><li><a title="Vanities" href="/index.php?r=images/sddsd&amp;id=2">Vanities</a></li></ul> </li> </ul> <ul class="sf-menu sf-navbar "> <li> <a href="?sid=3" class="sf-with-ul " >ACCESSORIES</a> <ul class="subs" id=""><li class="arrow"><img src="images/arrow.gif" /></li><li><a title="Door Handles" href="/index.php?r=images/sddsd&amp;id=2">Door Handles</a></li><li><a title="Spanners" href="/index.php?r=images/sddsd&amp;id=1">Spanners</a></li></ul> </li> </ul> <ul class="sf-menu sf-navbar "> <li> <a title="CONTACT US" class="sf-with-ul " href="/index.php?r=site/contact&amp;sid=4">CONTACT US</a> </li> </ul> </div> </div> and then the superfish code $(function(){ $("ul.sf-menu").superfish({ delay: 0, speed: 'fast', autoArrows: false, dropShadows: false }); }); I've also noticed that the following css code is used to display the item left: 0; top: 2.5em; z-index: 99;

  • Can't finish Eclipse Plug-in Project Wizard when choosing RCP

    - by Jens Schauder
    I'm trying create a RCP Application with Eclipse, but I can't get past the 'Content' screen of the New Plug-in Project Wizard. When I select 'yes' for "Rich Client Application, Would you like to create a rich client application" it disables the Next and the Finish Button. I first thought it is due to my target platform which is Eclipse 3.2, but changing that doesn't make a difference. On the top of the screen only one task is displayed (now warnings about missing or incompatible information): Enter the data required to generate the plug-in My Eclipse Version is 3.5 Any ideas? Since it was asked. A screenshot can be found here: http://www.flickr.com/photos/jensschauder/4535101973/

  • Widgets and .mobi sites, is this possible?

    - by Roland
    I have a couple of concerns, I'm busy building a normal .mobi site for a client, so basically how I understand this is keep it simply since most phones do not support JavaScript and have a small screen etc. So I build a mobi site using only content and basic links. Now my question is how do mobi widgets work on a mobile site? I've googled and could not find a answer? Is this possible at all?

  • CSS-Specifity and CSS Inheritance (concrete question)?

    - by jens
    Hello, i would by thankful for an official link (and section) of the specification for CSS, that explains if: .one two h1 {color:green;font-family:arial;} /*case 1 */ .one two h1 {color:blue;} /*case 2*/ will result in (when evaluated by the browser) .one two h1 {color:blue;font-family:arial;} /*case 3*/ or will it be: .one two h1 {color:blue;} /*case 4*/ ==I have read a lot about inheritance, specifity, cascading etc but I still have not found for the given example which rules apply here. In regard to specifity both elements are equal in specifity the case2 will be the most specify one (as it is equal specific but the last one). But does specifity always apply to the whole selector with ALL properties defined. Or only the the properties that are are in "competition" (and declared in both). thanks!!!!

  • DRY for JMeter tests

    - by jens
    Is there a way to modularize JMeter tests. I have recorded several use cases for our application. Each of them is in a separate thread group in the same test plan. To control the workflow I wrote some primitives (e.g. postprocessor elements) that are used in many of these thread groups. Is there a way not to copy these elements into each thread group but to use some kind of referencing within the same test plan? What would also be helpful is a way to reference elements from a different file. Does anybody have any solutions or workarounds. I guess I am not the only one trying to follow the DRY principle...

  • Setting a date format in ASP.NET web.config globalization tag?

    - by Jens Ameskamp
    In our web.config I am using the following tag to determine the interface language of an ASP.NET website. <globalization enableClientBasedCulture="true" culture="auto:en-GB" uiCulture="auto:en"/> This works as expected: Client wo request a specific localisation get it, everybody else is happily looking at the en-GB settings. Due to company policy I need to change the date format to the ISO 8601 standard format (YYYY-MM-DD) for everybody. Is this possible at a central place in the web.config or do I need to change this manually in every instance? Addition: Would it be possible to do get this date format when restricting the interface to english? Thanks! =)

  • Mysql Powerdns issue when adding a new CName record

    - by Roland
    I'm trying to add a new CNAME record in PowerDNS to the mysql database, but my website does not want to show. When adding it in via Zone Admin it works, but as soon as I add the record as below it just does not want to work. Am I doing something wrong here. I checked if my record looks exactly the same in the DB as the record added with PowerDNS and it does. $type = 'CNAME'; //Adding the subdomain to the DNS database $sql = "insert into records " . "(domain_id, name,type,content,ttl,prio,change_date) values("; $sql .= $domain_id . ",'"; $sql .= trim($subdomain).".". trim($domain) . "','"; $sql .= trim($type) . "','"; $sql .= trim($domain) . "',"; $sql .= "3600,0,'".time()."')";

  • Anniversary gift for a programmer

    - by jens
    My boyfriend does coding (Rails/C?/PHP) for a job and I don't know what he would appreciate on our first anniversary. Does anyone have any ideas? Yes, he's stereotypical geek, but I'd rather not give a pack of Bawls for an anniversary gift. He dislikes going anywhere, so "experiences" like going to an event are out. Maybe I should just have a giant LAN party in the house.

  • echoing javascript when an ajax funtion is called

    - by Roland
    I'm doing a ajax call via the normal jquery ajax funtion My ajax looks as follows jQuery('#yt10').live('click',function(){jQuery.ajax({'data':{'set':$("#booking_set_id1").val(),'setStat':$("#booking_stockStatus").val(),'setNum':$("#booking_setNum").val()},'beforeSend':function(){ if($("#booking_set_id1").val() == "" || $("#booking_stockStatus").val() == "" || $("#booking_setNum").val() == ""){ $("#error").addClass("flash-error"); $("#error").html("Please fill in all relevant set details before adding a set"); return false; } },'dataType':'html','success':function(data,status){ $("#mainrow").show(); $("#error").removeClass("flash-error"); $("#error").html(""); $("#setTable tr:last").after(data); $("#booking_set_id1").val(""); $("#booking_stockStatus").val(""); $("#booking_setNum").val(""); },'url':'/booking/newSet','cache':false});return false;}); Now the function newSet needs to echo javascript to the bowser but somehow jquery filters the javscript out. Is it possible to echo javascript via ajax

  • NULL handling with subselect in Hibernate Criteria API

    - by Jens Schauder
    I'm constructing a Hibernate Criterion, using a subselect as follows DetachedCriteria subselect = DetachedCriteria.forClass(NhmCode.class, "sub"); // the subselect selecting the maximum 'validFrom' subselect.add(Restrictions.le("validFrom", new Date())); // it should be in the past (null needs handling here) subselect.add(Property.forName("sub.lifeCycle").eqProperty("this.id")); // join to owning entity subselect.setProjection(Projections.max("validFrom")); // we are only interested in the maximum validFrom Conjunction resultCriterion = Restrictions.conjunction(); resultCriterion.add(Restrictions.ilike(property, value)); // I have other Restrictions as well resultCriterion.add(Property.forName("validFrom").eq(subselect)); // this fails when validFrom and the subselect return NULL return resultCriterion; It works ok so far, but the restriction on the last line before the return statement is false when validFrom and subselect result in NULL. What I need is a version which handles this case as true. Possibly by applying a NVL or coalesce or similar. How do I do this?

  • Strange PHP reference bug

    - by Roland Soós
    Hello, I have a really strange bug with my PHP code. I have a recursive code which build up a menu tree with object and one of my customers server can't make it work. Contructor: function Menu(&$menus, &$keys , &$parent, &$menu){ ... if($keys === NULL){ $keys = array_keys($menus); } ... for($x = 0; $x < count($keys); $x++) { var_dump($keys); $menu = $menus[$keys[$x]]; var_dump($keys); if($this->id == $menu->pid){ $keys[$x] = NULL; $this->submenus[] = new Menu($menus, $keys, $this, $menu); } } First var_dump give me back the array, the second give back the first element of $menus.

    Is there anyway to implement a timer for JQuery, eg. every 10 seconds it needs to call a js function. I tried the following window.setTimeout(function() { alert('test'); }, 1000); but this only executes ones and then never again.

  • Signals and threads - good or bad design decision?

    - by Jens
    I have to write a program that performs highly computationally intensive calculations. The program might run for several days. The calculation can be separated easily in different threads without the need of shared data. I want a GUI or a web service that informs me of the current status. My current design uses BOOST::signals2 and BOOST::thread. It compiles and so far works as expected. If a thread finished one iteration and new data is available it calls a signal which is connected to a slot in the GUI class. My question(s): Is this combination of signals and threads a wise idea? I another forum somebody advised someone else not to "go down this road". Are there potential deadly pitfalls nearby that I failed to see? Is my expectation realistic that it will be "easy" to use my GUI class to provide a web interface or a QT, a VTK or a whatever window? Is there a more clever alternative (like other boost libs) that I overlooked? following code compiles with g++ -Wall -o main -lboost_thread-mt <filename>.cpp code follows: #include <boost/signals2.hpp> #include <boost/thread.hpp> #include <boost/bind.hpp> #include <iostream> #include <iterator> #include <string> using std::cout; using std::cerr; using std::string; /** * Called when a CalcThread finished a new bunch of data. */ boost::signals2::signal<void(string)> signal_new_data; /** * The whole data will be stored here. */ class DataCollector { typedef boost::mutex::scoped_lock scoped_lock; boost::mutex mutex; public: /** * Called by CalcThreads call the to store their data. */ void push(const string &s, const string &caller_name) { scoped_lock lock(mutex); _data.push_back(s); signal_new_data(caller_name); } /** * Output everything collected so far to std::out. */ void out() { typedef std::vector<string>::const_iterator iter; for (iter i = _data.begin(); i != _data.end(); ++i) cout << " " << *i << "\n"; } private: std::vector<string> _data; }; /** * Several of those can calculate stuff. * No data sharing needed. */ struct CalcThread { CalcThread(string name, DataCollector &datcol) : _name(name), _datcol(datcol) { } /** * Expensive algorithms will be implemented here. * @param num_results how many data sets are to be calculated by this thread. */ void operator()(int num_results) { for (int i = 1; i <= num_results; ++i) { std::stringstream s; s << "["; if (i == num_results) s << "LAST "; s << "DATA " << i << " from thread " << _name << "]"; _datcol.push(s.str(), _name); } } private: string _name; DataCollector &_datcol; }; /** * Maybe some VTK or QT or both will be used someday. */ class GuiClass { public: GuiClass(DataCollector &datcol) : _datcol(datcol) { } /** * If the GUI wants to present or at least count the data collected so far. * @param caller_name is the name of the thread whose data is new. */ void slot_data_changed(string caller_name) const { cout << "GuiClass knows: new data from " << caller_name << std::endl; } private: DataCollector & _datcol; }; int main() { DataCollector datcol; GuiClass mc(datcol); signal_new_data.connect(boost::bind(&GuiClass::slot_data_changed, &mc, _1)); CalcThread r1("A", datcol), r2("B", datcol), r3("C", datcol), r4("D", datcol), r5("E", datcol); boost::thread t1(r1, 3); boost::thread t2(r2, 1); boost::thread t3(r3, 2); boost::thread t4(r4, 2); boost::thread t5(r5, 3); t1.join(); t2.join(); t3.join(); t4.join(); t5.join(); datcol.out(); cout << "\nDone" << std::endl; return 0; }

  • Ho to convert classname as string to a class ?

    - by Roland Bengtsson
    I have classnames in a stringlist. For example it could be 'TPlanEvent', 'TParcel', 'TCountry' etc. Now I want to find out the sizes by looping the list. It works to have: Size := TCountry.InstanceSize; But I want it like this: for i := 0 to ClassList.Count - 1 do Size := StringToClass(ClassList[i]).InstanceSize; Obviously my question is what to write instead of method StringToClass to convert the string to a class.

  • Trouble understanding the whole OSGi web eco system

    - by Jens
    Hello, I am pretty new to the whole Java and OSGi world and I have trouble understanding the eco system of a OSGi web application. To be more precise I am at the moment trying to understand how all the parts of the eco system are related to each other: OSGi Framework (e.g. Apache Felix, Equinox, Knoplerfish) OSGi Runtime (e.g. Spring DM Server, Pax Runner, Apache Karaf) Web Extender (e.g. Pax Web Extender, Spring Web Extender) Web Container (e.g. Apache Tomcat, Jetty) To give you a visual representation of my actual understanding of their relationship check out this image: As far as I know the OSGi Framework is a implementation of the OSGi specification. The runtime is a distribution which adds additional functionality on top of the OSGi specification like logging for instance. Since there seem to be some differences in the classpath mechanism of OSGi and web containers like Tomcat you need some kind of translator. This part is handled by the "Web Extender". Would you please clarify this whole thing for me? Am I understanding everything correct?

  • How to change rowHeight of a TableViewCell depending on Stringlength

    - by Jens Koehler
    I have a table with different entries, each with different length. The height of each row should fit, so it can show the whole string. I use the following code: //... cellForRowAtIndexPath if (row == 0) { cell = [tableView dequeueReusableCellWithIdentifier:@"affCell"]; //if (!cell) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"affCell"]autorelease]; cell.accessoryType = UITableViewCellAccessoryNone; cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.autoresizingMask = UIViewAutoresizingFlexibleHeight; affL = [[UILabel alloc] initWithFrame:CGRectZero]; affL.textAlignment = UITextAlignmentLeft; affL.autoresizingMask = UIViewAutoresizingFlexibleHeight; [cell.contentView addSubview:affL]; //} //declaration label affL.text = [fDictionary objectForKey:@"aff"]; affL.numberOfLines = 0; [affL sizeToFit]; affL.frame = CGRectMake(15.0, 10.0, 220.0, affL.frame.size.height); CGFloat affLH = affL.frame.size.height; [tableView setRowHeight:affLH+30]; I also use //... heightForRowAtIndexPath return affL.frame.size.height; How can I fix this problem?

  • Why 2 GB memory limit when running in 64 bit Windows ?

    - by Roland Bengtsson
    I'm a member in a team that develop a Delphi application. The memory requirements are huge. 500 MB is normal but in some cases it got out of memory exception. The memory allocated in that cases is typically between 1000 - 1700 MB. We of course want 64-bits compiler but that won't happen now (and if it happens we also must convert to unicode, but that is another story...). My question is why is there a 2 GB memory limit per process when running in a 64 bit environment. The pointer is 32 bit so I think 4 GB would be the right limit. I use Delphi 2007.

  • Detect the URI encoding automatically in Tomcat

    - by Roland Illig
    I have an instance of Apache Tomcat 6.x running, and I want it to interpret the character set of incoming URLs a little more intelligent than the default behavior. In particular, I want to achieve the following mapping: So%DFe => Soße So%C3%9Fe => Soße So%DF%C3%9F => (error) The bevavior I want could be described as "try to decode the byte stream as UTF-8, and if it doesn't work assume ISO-8859-1". Simply using the URIEncoding configuration doesn't work in that case. So how can I configure Tomcat to encode the request the way I want? I might have to write a Filter that takes the request (especially the query string) and re-encodes it into the parameters. Would that be the natural way?

  • Daily, Weekly and Monthly Page View Counter

    - by Jens Fahnenbruck
    I'm building a website with user generated content. On the home page I want to show a list of all created items, and I want to be able to sort them by a view counter. That's sound easy, but I want multiple counters. I want to know which was the most visited item in the last day, last week or last months or overall. My first Idea was to create 4 counter columns in the item's DB-Table. One for each of daily, weekly, monthly and overall, and the create a cron job, that clears the daily counter every 24 hours, the weekly counter every 7 days and so on. But my problem with this is, what happens if I want to know which was the most viewed item of the week, just after the weekly counter got cleared? What I need is an efficient way to create a continous counter, which got reduced for every page view that is too old, and increased for every new page view. Right now I'm thinking of a solution with the redis server, but I have no solution yet. I'm just looking for a general idea here, but FYI I'm developing this application in Ruby on Rails.

  • Can I use a previous version of iText(Sharp) under the LGPL?

    - by Jens
    I'd like to use iTextSharp for PDF manipulation. I need it to run under medium trust (webserver) and to be free of charge (sice this is a very small project), therefore there is not much competition. Unfortunately, since I need it for a commercial project, I cannot the AGPL introduced with version 5.0. Do you know if I may use the 4.x versions using the LGPL? Or is their license automatically updated to the APGL?

  • Sending most correct mimetype

    - by Roland Franssen
    Hi all, I have a list of extension to mimetype in a INI file. However some extensions have multiple mimetypes, for example; midi[] = "application/x-midi" midi[] = "audio/midi" midi[] = "audio/x-mid" midi[] = "audio/x-midi" midi[] = "music/crescendo" midi[] = "x-music/x-midi" 6 (possible) mimetypes for 1 extension. Whats common practice to determine the correct mimetype? (e.g. i need to set a HTTP content-type header). I know its not ideal; determining mimetypes based on extension.. but i need consistent (cross-server) results (e.g. fileinfo extension in PHP is making terrible guesses*). * Some fileinfo results for example; js - text/plain css - text/c-h
