  • Which class for making many replacements

    - by HCL
    I have to make a lot of text-replacements. Which class is best used to make this in a performant manner. Is it StringBuilder? StringBuilder stringBuilder=new StringBuilder(startString); stringBuilder.Replace(literala1,literala2); stringBuilder.Replace(literalb1,literalb2); stringBuilder.Replace(literalc1,literalc2); ... or does exists a better class to do this. Btw, the literals will be mostly constants.

  • Trouble rendering a view inside a generic class

    - by Horace Loeb
    I'm trying to encapsulate the logic for generating my sitemap in a separate class so I can use Delayed::Job to generate it out of band: class ViewCacher include ActionController::UrlWriter def initialize @av = ActionView::Base.new(Rails::Configuration.new.view_path) @av.class_eval do include ApplicationHelper end end def cache_sitemap songs = Song.all sitemap = @av.render 'sitemap/sitemap', :songs => songs Rails.cache.write('sitemap', sitemap) end end But whenever I try ViewCacher.new.cache_sitemap I get this error: ActionView::TemplateError: ActionView::TemplateError (You have a nil object when you didn't expect it! The error occurred while evaluating nil.url_for) on line #5 of app/views/sitemap/_sitemap.builder: I assume this means that ActionController::UrlWriter is not included in the right place, but I really don't know

  • Define Javascript slider hit/rollover area

    - by Rob
    Hey, Im having an issue defining the hit area for a javascript sliding element. See example: http://www.warface.co.uk/clients/warface.co.uk/ Please slide over the grey box on the right side to reveal the button, although this works I would only like for the slider to only be triggered by rolling over the red block. CSS .slidingtwitter { /* -- This is the hit area -- */ background: #ccc; width:255px; height:55px; overflow: hidden; top:50%; right: 0px; /* -- This is the sliding start point -- */ position: fixed; font-family: Gotham, Sans-Serif; z-index: 50; } .slidingtwitter.right { right:0px; } .slidingtwitter .caption { /* -- This is the sliding area -- */ background: #fff; position: absolute; width:260px; height:55px; right: -205px; /* -- This is the sliding start point -- */ } .slidingtwitter a { color: #484848; font-size: 20px; text-transform: uppercase; } .slidingtwitter a:hover { color: black; } .slidingtwitter .smaller { font-size: 12px; font-family: Gotham Medium; } .twitterblock { background: #f35555 url("styles/images/button_twitter.png") no-repeat 14px 15px ; width:35px; height:35px; padding:10px; float:left; display:block; } .slidingtwitter .followme { background: url("styles/images/button_arrowheadthin.jpg")no-repeat right 0; height:35px; display:block; float:left; line-height:14px; width:140px; margin:10px 0px 0px 14px; padding-top:6px; padding-right: 40px; } JS $('.slidingtwitter').hover(function(){ $(".slide", this).stop().animate({right:'0px'},{queue:false,duration:400}); //Position on rollover },function() { $(".slide", this).stop().animate({right:'-205px'},{queue:false,duration:400}); //Position on rollout }); Any suggestions would be much appreciated.

  • Hiding Text in ie7

    - by user356849
    So I have this text generated by a javascript plugin. <a class="className">Text</a> a.className { background: url(images/a-image.png) no-repeat; } But the "Text" shows on top of the image... Now... with any respectable web browser, I can use color: rgba(0,0,0,0); to solve the problem, but IE7 doesn't obey standards of any sort. Any ideas?

  • Casting to specific class in HQL

    - by bungrudi
    My situation is like this.. (note: for those who work with JBPM might already familiar with following data structures and HB mapping) Class LongInstance extends from VariableInstance, with the mapping for field "value" overridden in LongInstance. The mapping for VariableInstance is here and for LongInstance here. VariableInstance is polymorphically mapped to a collection in TokenVariableMap, the mapping is here. The question: how can I query the polymorphic collection using specific/overridden property of the member class? I'm looking for something like this "... from TokenVariableMaps tvm left join fetch tvm.variableInstances tvi where cast(tvi as LongInstance).value in(:vars)"

  • PHP Session Class and $_SESSION Array

    - by Gianluca Bargelli
    Hello, i've implemented this custom PHP Session Class for storing sessions into a MySQL database: class Session { private $_session; public $maxTime; private $database; public function __construct(mysqli $database) { $this->database=$database; $this->maxTime['access'] = time(); $this->maxTime['gc'] = get_cfg_var('session.gc_maxlifetime'); session_set_save_handler(array($this,'_open'), array($this,'_close'), array($this,'_read'), array($this,'_write'), array($this,'_destroy'), array($this,'_clean') ); register_shutdown_function('session_write_close'); session_start();//SESSION START } public function _open() { return true; } public function _close() { $this->_clean($this->maxTime['gc']); } public function _read($id) { $getData= $this->database->prepare("SELECT data FROM Sessions AS Session WHERE Session.id = ?"); $getData->bind_param('s',$id); $getData->execute(); $allData= $getData->fetch(); $totalData = count($allData); $hasData=(bool) $totalData >=1; return $hasData ? $allData['data'] : ''; } public function _write($id, $data) { $getData = $this->database->prepare("REPLACE INTO Sessions VALUES (?, ?, ?)"); $getData->bind_param('sss', $id, $this->maxTime['access'], $data); return $getData->execute(); } public function _destroy($id) { $getData=$this->database->prepare("DELETE FROM Sessions WHERE id = ?"); $getData->bind_param('S', $id); return $getData->execute(); } public function _clean($max) { $old=($this->maxTime['access'] - $max); $getData = $this->database->prepare("DELETE FROM Sessions WHERE access < ?"); $getData->bind_param('s', $old); return $getData->execute(); } } It works well but i don't really know how to properly access the $_SESSION array: For example: $db=new DBClass();//This is a custom database class $session=new Session($db->getConnection()); if (isset($_SESSION['user'])) { echo($_SESSION['user']);//THIS IS NEVER EXECUTED! } else { $_SESSION['user']="test"; Echo("Session created!"); } At every page refresh it seems that $_SESSION['user'] is somehow "resetted", what methods can i apply to prevent such behaviour?

  • conditional inline div styling (help!)

    - by AMC
    I have div that I need to be present on every page, yet at a different length depending on the exact page. So far, I have this: <div class="above <?php if (is_page(12)) echo 'short'; ?>"> //content </div><!-- end above --> How do I go about adding something to the avail of <?php if (is_page(24, 26, 28)) echo 'med'; ?> (on page 12 I need the "short" length, and on pages 24, 26, 28 I need the "med" length of the div) Any help is appreciated. I'm just now diving into php and while I do love the options it makes available, I'm not sure yet how to put it all together.

  • How do you learn a class hierarchy quickly?

    - by rsteckly
    Hi, Something I don't enjoy about programming is learning a new API. For example, right now I'm trying to learn Windows Identity Foundation. Its frustrating because I'm going to spend the bulk of the time learning how a few classes work and actually only write several lines of code. In .NET, there are so many types that I seem to spend more time hunting around in msdn for a class than writing code. It also interrupts my workflow while I'm working because I have to type a little bit than look something up. Obviously, I don't have to do this for the basic classes. Whenever new things come though there is definitely some looking up to do. Then I often don't reuse that class enough to really review it or bring it into action. I'm wondering if anybody out there has a found a way to memorize (or look up more efficiently) these object model hierarchies?

  • Stretching DIV to 100% height and width of window but not less than 800x600px

    - by El Eme
    I have a page that needs to stretch and resize with with window and I've managed to do that but I need that the "inner div" (#pgContent) stretch if the window is resized to higher dimensions but that it doesn't shrink more than, let's say for example 800 x 600 px. As I have it now it stretches well but it also shrinks more than I want! It's working as I want in width but not in height!? Here's a visual example: My CSS: * { margin: 0; padding: 0; outline: 0; } /*| PAGE LAYOUT |*/ html, body { height: 100%; width: 100%; /*text-align: center;*/ /*IE doesn't ~like this*/ cursor: default; } #pgWrapper { z-index: 1; min-height: 100%; height: auto !important; /*min-height: 600px;*/ /* THIS SHOULD WORK BUT IT DOESN'T */ height: 100%; min-width: 1000px; width: 100%; position: absolute; overflow: hidden; text-align: center; background: #000; } #pgContent { position: absolute; top: 30px; left: 30px; right: 30px; bottom: 50px; overflow: hidden; background: #CCC; } #footWrapper { z-index: 2; height: 50px; min-width: 940px; position: absolute; left: 30px; right: 30px; bottom: 0px; background: #C00; } /*| END PAGE LAYOUT |*/ And the HTML: <body> <div id="pgWrapper"> <div id="pgContent"> This DIV should stretch with window but never lower than for example 800px x 600px!<br /> If window size is lower then scrollbars should appear. </div> </div> <div id="footWrapper"> <div id="footLft"></div> <div id="footRgt"></div> </div> </body> If someone could give me a help on this I would appreciate. Thanks in advance.

  • [N]Hibernate: view-like fetching properties of associated class

    - by chiccodoro
    (Felt quite helpless in formulating an appropriate title...) In my C# app I display a list of "A" objects, along with some properties of their associated "B" objects and properties of B's associated "C" objects: A.Name B.Name B.SomeValue C.Name Foo Bar 123 HelloWorld Bar Hello 432 World ... To clarify: A has an FK to B, B has an FK to C. (Such as, e.g. BankAccount - Person - Company). I have tried two approaches to load these properties from the database (using NHibernate): A fast approach and a clean approach. My eventual question is how to do a fast & clean approach. Fast approach: Define a view in the database which joins A, B, C and provides all these fields. In the A class, define properties "BName", "BSomeValue", "CName" Define a hibernate mapping between A and the View, whereas the needed B and C properties are mapped with update="false" insert="false" and do actually stem from B and C tables, but Hibernate is not aware of that since it uses the view. This way, the listing only loads one object per "A" record, which is quite fast. If the code tries to access the actual associated property, "A.B", I issue another HQL query to get B, set the property and update the faked BName and BSomeValue properties as well. Clean approach: There is no view. Class A is mapped to table A, B to B, C to C. When loading the list of A, I do a double left-join-fetch to get B and C as well: from A a left join fetch a.B left join fetch a.B.C B.Name, B.SomeValue and C.Name are accessed through the eagerly loaded associations. The disadvantage of this approach is that it gets slower and takes more memory, since it needs to created and map 3 objects per "A" record: An A, B, and C object each. Fast and clean approach: I feel somehow uncomfortable using a database view that hides a join and treat that in NHibernate as if it was a table. So I would like to do something like: Have no views in the database. Declare properties "BName", "BSomeValue", "CName" in class "A". Define the mapping for A such that NHibernate fetches A and these properties together using a join SQL query as a database view would do. The mapping should still allow for defining lazy many-to-one associations for getting A.B.C My questions: Is this possible? Is it [un]artful? Is there a better way?

  • Operator Overloading for Queue C++

    I was trying to use the overload operator method to copy the entries of one queue into another, but I am going wrong with my function. I don't know how else to access the values of the queue "original" any other way than what I have below: struct Node { int item; Node* next; }; class Queue { public: [...] //Extra code here void operator = (const Queue &original); protected: Node *front, *end; } void Queue::operator=(const Queue &original) { //THIS IS WHERE IM GOING WRONG while(original.front->next != NULL) { front->item = original.front->item; front->next = new Node; front = front->next; original.front = original.front->next; } }

  • C Class Instance from Void Pointer using Ctypes

    - by g.d.d.c
    I've got a C DLL that exposes a handful of methods that return void pointers to a Class like so: void *GetLicense() { static AppLicenseImpl ipds_; return (void *) &ipds_; } In C++, after loading the DLL, I'd do this to work with it: typedef void *(* FPGetLicense)(); GetLicense_ = (FPGetLicense)GetAddress("GetLicense"); license_ = (AppLicense *) GetLicense_(); license_->GetApplicationStatus(); // Load data so that other calls don't fail I can't figure out how to parallel that in Python. This gets me the pointer: d = ctypes.cdll.LoadLibrary('license.dll') d.GetLicense.restype = ctypes.c_void_p p = d.GetLicense() # returns ptr loc, something like 8791433660848L But I obviously can't call p.GetApplicationStatus() in Python. Does anyone have a suggestion on how I'd instantiate that Class the rest of the way in Python so that I can call GetApplicationStatus()?

  • How to get details like PHP's stat() but using (raw) FTP (CURL)?

    - by Christian Sciberras
    Hello all! I'm new here. I've got a question related to PHP, FTP and CURL. I need to emulate PHP's stat() with CURL FTP. I already know that it may take more than one command to do it. Here's what I've got so far (PHP/STAT ... FTP/CURL): dev ino mode ... LIST * nlink uid ... LIST * gid ... LIST * rdev size ... SIZE (or better still, use from LIST) atime mtime ... MDTM ctime blksize blocks *How is FTP LIST used and parsed (preferably on a single file)? What I need most are the values for atime and ctime, there rest is to be filled for the sake of having full functionality. My end goal is to have a class for proper FTP access with streamWrapper functionality (so as to bypass allow_url_fopen). Cheers!

  • PHP Global variable in class is reset

    - by Robert
    I have a web form that manipulates records in a MySQL database. I have a method for displaying an edit interface for both creating new records and editing them if ($_POST['new_page']) { print "<h2>Create new page</h2>\n"; $isNew=1; $this->EditForm(); } else if($_POST['edit']){ print "<h2>Edit page</h2>\n"; $isNew=0; $this->EditForm(); } I am trying to use the global variable $isNew to determine where a record is to be added or updated. However, whenever my SaveChanges() function is run, $isNew is always 0. $isNew is declared immediately after the class declaration, outside all of the functions. class Editor{ public $isNew;

  • Finding the attributes on the properties of an instance of a class

    - by Dan
    Given an instance of a class I want to set properties on attributes at runtime. So I tried this, but as far as I can tell this finds the attributes on the class not the instance, so any changes I make to the attribute properties have no effect. var properties = myObject.GetType().GetProperties(); foreach (object prop in properties) { var attribute =prop.GetCustomAttributes(typeof(MyAttribute), true)[0]; //attribute.MyProp do some stuff } If I try using type descriptor like below, there is no way of getting to the attributes on the properties. var myObject= (MyClass) object; PropertyDescriptorCollection props = TypeDescriptor.GetProperties(myObject); //There is no props[0].GetCustomAttributes(

  • How can I prevent page-break in CFDocument from occuring in middle of content?

    - by Dan Roberts
    I am generating a PDF file dynamically from html/css using the cfdocument tag. There are blocks of content that I don't want to span multiple pages. After some searching I found that the style "page-break-inside" is supported according to the docs. However in my testing the declaration "page-break-inside: avoid" does no good. Any suggestions on getting this style declaration to work, or have alternative suggestions? Here is an example. I would expect the content in the div tag not to span a page break but it does. The style "page-break-inside: avoid" is not being honored. <cfdocument format="flashpaper"> <cfloop from="1" to="10" index="i"> <div style="page-break-inside: avoid"> <h1>Table Label</h1> <table> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> <tr><td>label</td><td>data</td></tr> </table> </div> </cfloop> </cfdocument>
