  • Is it possible to make a subclass of NSObject which support subnodes in IB for iPhone project?

    - by Eonil
    I'm making a custom UI element class for iPhone. It'll cool to edit my class on Interface Builder with hierarchy. Some of my class is management class like UINavigationController, but they're not one of them, subclasses from NSObject. Of course, I can place a NSObject instance on IB, but it cannot have a child node. Is there a way to enable adding child node to subclass of NSObject?

  • Are there any nasty side affects if i lock the HttpContext.Current.Cache.Insert method

    - by Ekk
    Apart from blocking other threads reading from the cache what other problems should I be thinking about when locking the cache insert method for a public facing website. The actual data retrieval and insert into the cache should take no more than 1 second, which we can live with. More importantly i don't want multiple thread potentially all hitting the Insert method at the same time. The sample code looks something like: public static readonly object _syncRoot = new object(); if (HttpContext.Current.Cache["key"] == null) { lock (_syncRoot) { HttpContext.Current.Cache.Insert("key", "DATA", null, DateTime.Now.AddMinutes(5), Cache.NoSlidingExpiration, CacheItemPriority.Normal, null); } } Response.Write(HttpContext.Current.Cache["key"]);

  • python set difference

    - by user1311992
    I'm doing a set difference operation in Python: from sets import Set from mongokit import ObjectId x = [ObjectId("4f7aba8a43f1e51544000006"), ObjectId("4f7abaa043f1e51544000007"), ObjectId("4f7ac02543f1e51a44000001")] y = [ObjectId("4f7acde943f1e51fb6000003")] print list(Set(x).difference(Set(y))) I'm getting: [ObjectId('4f7abaa043f1e51544000007'), ObjectId('4f7ac02543f1e51a44000001'), ObjectId('4f7aba8a43f1e51544000006')] I need to get the first element for next operation which is important. How can I retain the list x in original format?

  • How can I refactor this JavaScript code to avoid making functions in a loop?

    - by Bungle
    I wrote the following code for a project that I'm working on: var clicky_tracking = [ ['related-searches', 'Related Searches'], ['related-stories', 'Related Stories'], ['more-videos', 'More Videos'], ['web-headlines', 'Publication'] ]; for (var x = 0, length_x = clicky_tracking.length; x < length_x; x++) { links = document.getElementById(clicky_tracking[x][0]) .getElementsByTagName('a'); for (var y = 0, length_y = links.length; y < length_y; y++) { links[y].onclick = (function(name, url) { return function() { clicky.log(url, name, 'outbound'); }; }(clicky_tracking[x][1], links[y].href)); } } What I'm trying to do is: define a two-dimensional array, with each instance the inner arrays containing two elements: an id attribute value (e.g., "related-searches") and a corresponding description (e.g., "Related Searches"); for each of the inner arrays, find the element in the document with the corresponding id attribute, and then gather a collection of all <a> elements (hyperlinks) within it; loop through that collection and attach an onclick handler to each hyperlink, which should call clicky.log, passing in as parameters the description that corresponds to the id (e.g., "Related Searches" for the id "related-searches") and the value of the href attribute for the <a> element that was clicked. Hopefully that wasn't thoroughly confusing! The code may be more self-explanatory than that. I believe that what I've implemented here is a closure, but JSLint complains: http://img.skitch.com/20100526-k1trfr6tpj64iamm8r4jf5rbru.png So, my questions are: How can I refactor this code to make JSLint agreeable? Or, better yet, is there a best-practices way to do this that I'm missing, regardless of what JSLint thinks? Should I rely on event delegation instead? That is, attaching onclick event handlers to the document elements with the id attributes in my arrays, and then looking at event.target? I've done that once before and understand the theory, but I'm very hazy on the details, and would appreciate some guidance on what that would look like - assuming this is a viable approach. Thanks very much for any help!

  • How to inject a "runtime" dependency like a logged in user which is not available at application boot time?

    - by Fabian
    I'm just not getting this: I use Gin in my java GWT app to do DI. The login screen is integrated into the full application window. After the user has logged in I want to inject the user object into other classes like GUI Presenters which I create, so I have some sort of runtime dependency I believe. How do i do that? One solution I can think of is sth like: class Presenter { @Inject Presenter(LoggedInUserFactory userFactory) { User user = userFactory.getLoggedInUser(); } } class LoggedInUserFactoryImpl { public static User user; User getLoggedInUser() { return user; } } So, when the user is successfully logged in and I have the object i set the static property in LoggedInUserFactory, but this will only work if the Presenter is created after the user has logged in which is not the case. Or should I use a global static registry? I just don't like the idea of having static dependencies in my classes. Any input is greatly appreciated.

  • Python try/except: Showing the cause of the error after displaying my variables

    - by NealWalters
    I'm not even sure what the right words are to search for. I want to display parts of the error object in an except block (similar to the err object in VBScript, which has Err.Number and Err.Description). For example, I want to show the values of my variables, then show the exact error. Clearly, I am causing a divided-by-zero error below, but how can I print that fact? try: x = 0 y = 1 z = y / x z = z + 1 print "z=%d" % (z) except: print "Values at Exception: x=%d y=%d " % (x,y) print "The error was on line ..." print "The reason for the error was ..."

  • Class not overwriting with addClass

    - by scatteredbomb
    I'm using jQuery's addClass to add a class to an tab so when clicked it'll change the class so it's obvious the tab is highlighted. My HTML <div id="mainNav"> <ul> <li id="LinktheBand" onclick="nav('theBand')">The Band</li> <li id="linkTheMusic" onclick="nav('theMusic')">The Music</li> My CSS #mainNav li { float:left; margin-right:5px; color:white; font-family:Tahoma; font-weight:bold; padding: 10px 8px 0px 8px; background:url('../images/transparent-65.png'); height:40px; height: 25px !important; border:1px solid #000; } #mainNav li:hover { float:left; margin-right:5px; color:white; font-family:Tahoma; font-weight:bold; padding: 10px 8px 0px 8px; background: #660000; height:40px; height: 25px !important; border:1px solid #660000; } .mainNavSelected { float:left; margin-right:5px; color:white; font-family:Tahoma; font-weight:bold; padding: 10px 8px 0px 8px; background: #660000; height:40px; height: 25px !important; border:1px solid #660000; } My Javascript function nav(a) { $('#'+a).show(); $('#Link'+a).addClass('mainNavSelected'); } This works properly, I check firebug and can see the class="mainNavSelected" is added, but the list element doesn't take any properties of the new class. Firebug lists all the class items for mainNavSelected, but has them all crossed out. What am i missing to replace the class of this element?

  • Why in Ruby, a || 1 will throw an error when `a` is undefined, but a = a || 1 will not?

    - by Jian Lin
    When a is undefined, then a || 1 will throw an error, but a = a || 1 will not. Isn't that a little bit inconsistent? irb(main):001:0> a NameError: undefined local variable or method `a' for main:Object from (irb):1 from c:/ruby/bin/irb:12:in `<main>' irb(main):002:0> a || 1 NameError: undefined local variable or method `a' for main:Object from (irb):2 from c:/ruby/bin/irb:12:in `<main>' irb(main):003:0> a = a || 1 => 1

  • MATLAB: comparing all elements in three arrays

    - by sasha
    I have three 1-d arrays where elements are some values and I want to compare every element in one array to all elements in other two. For example: a=[2,4,6,8,12] b=[1,3,5,9,10] c=[3,5,8,11,15] I want to know if there are same values in different arrays (in this case there are 3,5,8)

  • Soften a colour border, maybe with a gradient, programmatically.

    - by ProfK
    I have a narrow header in corporate colour, bright red, with the content below on a just-off-white background. Ive tried softening the long line where these colours meet using border type divs with intermediate backgrounds, but I think I need the original type curved gradient 'area transitions'. I could copy the 1024px wide, and too narrow (vertically), header gif from their web site, and chop it up for eight border images, but that seems clumsy, and I'm looking for something I can apply anywhere, without needing images. I am able to do round borders in the x-y plane, but I'm curious as to how I can apply a gradient to any chosen colour transition. The extra divs I'm using as border elements above and below '#top-section' arose when I was toying with making many divs for one bordered element. This seemed the ultimate in border manipulation, sans code, but very tedious to spec in CSS and lay out a new border for each bordered element. <div id="topsection"> <div style="float: right; width: 300px; padding-right: 5px;"> <div style="font-size: small; text-align: right;"> Provantage Media Management System</div> <div style="font-size: x-small; text-align: right;"> <asp:LoginStatus ID="loginStatus" runat="server" LoginText="Log in" LogoutText="Log out" /> </div> </div> <span style="padding-left: 15px;">Main Menu</span><span id="content-title"> <asp:ContentPlaceHolder ID="titlePlaceHolder" runat="server"> </asp:ContentPlaceHolder> </span> <div style="background-color: white; height: 2px;"> </div> <div style="background-color: white; height: 3px;"></div> And the CSS: #topsection { background-color: #EB2728; color: white; height: 35px; font-size: large; font-weight: bold; }

  • C# method generic params parameter bug?

    - by Mike M
    Hey, I appears to me as though there is a bug/inconsistency in the C# compiler. This works fine (first method gets called): public void SomeMethod(string message, object data); public void SomeMethod(string message, params object[] data); // .... SomeMethod("woohoo", item); Yet this causes "The call is ambiguous between the following methods" error: public void SomeMethod(string message, T data); public void SomeMethod(string message, params T[] data); // .... SomeMethod("woohoo", (T)item); I could just use the dump the first method entirely, but since this is a very performance sensitive library and the first method will be used about 75% of the time, I would rather not always wrap things in an array and instantiate an iterator to go over a foreach if there is only one item. Splitting into different named methods would be messy at best IMO. Thoughts?

  • Where do I put inline script in head with Zend Framework?

    - by Joel
    I'm reading the manual here: http://zendframework.com/manual/en/zend.view.helpers.html but I'm still confused. I have a script in my head that I'm converting to the layout/view for the Zend MVC: <script type="text/javascript"> var embedCode = '<object data="http://example.com" type="application/x-shockwave-flash" height="385" width="475"><param name="src" value="http://example.com" /><param name="allowfullscreen" value="true" /></object>' </script> I first tried to add it is an external file like this (in layout): $this->headScript()->appendFile('js/embeddedVideo.js')->appendScript($onloadScript); <head> <?php echo $this->headScript(); ?> </head> Didn't really work, but anyway, I'm wanting to just add the script and not add it as an external file. How do I do that? Thanks!

  • Flex: Change line height of Label component

    - by ChrisInCambo
    Hi guys, Maybe I'm googling for the wrong thing but I can't find anything on this. How can I change the line height of a Label element in Flex? I have two labels in a VBox and there is quite a lot of white space between them which I would like to reduce. There's no line height property and setting the height property causes overlap. Thanks in advance for any help! Cheers, Chris

  • Generating custom-form documents from base-form plus XML?

    - by KlaymenDK
    Hi all, this is my first stack overflow, and it's a complex one. Sorry. My task is to generate custom documents from a basic template plus some XML without having a custom form design element for each case. Here's the whole picture: We are building a Lotus Notes (client, not web) application for world-wide application access control; the scope is something like 400.000 users being able to request access to any of 1000+ applications. Each application needs its own request form -- different number of approvers, various info required, that sort of thing. We simply can't have a thousand forms in a database (one per application), and anyway their maintenance really needs to be pushed from the developers to the application owners. So instead of custom forms, we'd like to create a generic "template" form that stores a block of basic fields, but then allows application owners to define another block of fields dynamically -- "I want a mandatory plain-text field named 'Name' here, and then a date field named 'Due' here that must be later than today's date, and then ...". I hope this makes sense (if not, think of it as a generic questionnaire application). I pretty much have the structure in place for designing the dynamic fields (form builder GUI - XML-encoded data - pre-rendered DXL for injecting into a form), including mark-up for field types, value options, and rudimentary field validation instructions. My problem is generating a document with this dynamic content injected at the proper location (without needing a custom form design element for each case). Doing the dynamic content via HTML is out. The Notes client web rendering is simply way too poor, and it would be quite a challenge to implement things like field validation instructions, date selectors, and name look-ups. DXL, on the other hand, would allow us to use native Notes fields and code. As a tech demo, I've managed to implement a custom form generator that injects the pre-rendered DXL for the dynamic content into a base form; but as I said, we don't want a ton of custom form design elements. I've tried to implement a way to create a document with the "store form in document" flag set, but once I've created the document from the base form, I can't get DXL access to the stored form design, and so I can't inject my dynamic content. I know this is not something Notes was ever intended to do. Has anyone ever tried something like it (and gotten away with it)? Thanks for reading this far. With a boatload of thanks in advance, Jan Gundtofte-Bruun

  • MPXJ in .NET converting java Date to .NET DateTime

    - by Jeff
    I'm using the MPXJ library in .NET for parsing MS Project (MPP) files, and it's working great. The one issue I'm having is trying to translate the task Start and Finish date into .NET DateTime to use with my data models. I am going through all the tasks and calling task.getFinish() and task.getStart() that both return javva.util.Date objects. When I use task.getFinish().getYear(), task.getFinish().getMonth(), etc. to build up a new DateTime object it warns me that they are obsolete. What is the best way to get the start and finish dates from MPXJ into a .NET DateTime object? Thanks.

  • UTF-8 character encoding in Java

    Hello, I am having some problems getting some French text to convert to UTF8 so that it can be displayed properly, either in a console, text file or in a GUI element. The original string is HANDICAP+ES which is supposed to be HANDICAPÉES No matter how I tried converting it, it appears the same way. Any ideas on how I can do this conversion? Thanks, Cam

  • SVG Parser in Javascript

    I believe that at one point, I saw a TinySVG implementation that worked in the browser, using the canvas element as the backend. I found a few sites that appeared to indicate it was at http://fuchsia-design.com/CanvaSVG/, however, that site appears to no longer exist. Is this project (or a similar one) still on the web anywhere?

    I am triggering the transformation using a .NET code, unless I add "EnableDocumentFunction" property to the XSL-Setting, the program throws error saying ..

  • Temporary Onmouseover

Something like this: document.getElementByTagName ("div")[0].ontemporarymouseover = function () { // LoL this.style.backgroundColor = "red"; } Thanks
