  • Call method with parameters after animation completion

    - by Jean
    I want to call a method with certain parameters once an animation is done. The flow is something like this: -(void) myMethod:(int)val { [self performAnimation]; [self doSomethingElse:val]; // This should be done after animation completion } I presume the 'doSomethingElse' method needs to be called from the method defined in 'setAnimationDidStopSelector' - or is there a way to have the animation block until done? What is the best way to let the method called on 'setAnimationDidStopSelector' know about the method it needs to call and its parameter? Can this be done with selectors? Or is the only way of doing this by storing the methods and its params in class temp variables and access them when needed?

  • Need to make sure value is within 0-255

    - by igor
    This is probably really easy, but I'm lost on how to "make sure" it is in this range.. So basically we have class Color and many functions to implement from it. this function I need is: Effects: corrects a color value to be within 0-255 inclusive. If value is outside this range, adjusts to either 0 or 255, whichever is closer. This is what I have so far: static int correctValue(int value) { if(value<0) value=0; if(value>255) value=255; } Sorry for such a simple question ;/

  • generating images with php based on css3 gradient settings?

    - by thrice801
    Hi, Does anyone know if there is a php library, or if there isnt, have any input on how one would go about generating an image via php, from basic HTML element input settings, and CSS 3 gradient parameters. To give an example on why this would be useful, I have found as of a couple days ago, that laying out the wireframe for a webpage using basic Css3 gradient styling speeds up my design and development time by, well, alot. I cant design from photoshop, Ill spend hours tweaking stupid little things that only lead to me tweaking more stupid little things to compensate for stupid little changes. -- So, I had an epiphany to stop using photoshop until the end, and just focus on the main styling of elements, text-shadow, and borders for highlights, and I feel I am able to make super clean, more focused layout by being more restricted to the basics of graphic design with just css. Anyways, so Im planning on after I have the layouts done, to then recreate the graphics in photoshop, so that every browser is able to render the images. This wont take long, but as far as repeating it goes, if I could just do it with PHP, that would be incredible. For instance, take this style for example, which renders a clean looking ipad/pod ish menu/button gradient. [code] background: -moz-linear-gradient(top, #808080, #454545 50%, #313131 51%, #333333); background: -webkit-gradient(linear, left top, left bottom, color-stop(0, #808080), color-stop(.5, #454545), color-stop(.5, #313131), to(#333333));[/code] Basically what Im looking to do is take one or more inputs that control rendering the image as you see there. Take a width and a height input, and then render the image gradient accordingly, so I can save it, upload it and then use it in my designs. So ya, I know PHP has some image generation capabilities but I dont know to what extent, any input on the most effective way to go about doing this or whether it already exists, would be appreciated!

  • Having trouble deselecting all jquery tabs

    - by Julian
    I set up some jQuery tabs to start off with no tabs selected like this: $('#tabs').tabs( { selected: -1 } ); Then I also have a separate link that when pressed needs to deselect all the tabs. $("#deselectButton").click(function(){ $('#tabs').tabs( 'select' , -1 ) }); or $("#deselectButton").click(function(){ $('#tabs').tabs( 'selected' , -1 ) }); The deselectButton click does deselect the tabs content, however the tabs title remains active with the class 'ui-tabs-selected ui-state-active'. What is the correct way to deselect all the tabs?

  • C# HttpRequest - Accessing hashtags in url

    - by CloudyOne
    Unfortunately because of the wide use of the word "hashtag" and "httprequest" i couldn't find any search results that gave me an answer on whether something like this is even possible. If i have a url like this: /Orders/Product#12345 The HttpRequest class shows me that the FilePath, RawUrl, and all other members that show the url as /Orders/Product It just gets rid of the hashtag, and i can't find a place to view it. Is there any way for me to be able to see what hashtag is on the end of the URL from the codebehind? I know i could easily make this a QueryString parameter, but i like the way this looks better, so if there's a way to do it, i'd like to find out what it is :) Thanks in advance!

  • Entity Framework: Data Centric vs. Object Centric

    - by Eric J.
    I'm having a look at Entity Framework and everything I'm reading takes a data centric approach to explaining EF. By that I mean that the fundamental relationships of the system are first defined in the database and objects are generated that reflect those relationships. Examples Quickstart (Entity Framework) Using Entity Framework entities as business objects? The EF documentation implies that it's not necessary to start from the database layer, e.g. Developers can work with a consistent application object model that can be mapped to various storage schemas When designing a new system (simplified version), I tend to first create a class model, then generate business objects from the model, code business layer stuff that can't be generated, and then worry about persistence (or rather work with a DBA and let him worry about the most efficient persistence strategy). That object centric approach is well supported by ORM technologies such as (n)Hibernate. Is there a reasonable path to an object centric approach with EF? Will I be swimming upstream going that route? Any good starting points?

  • Does the order of readonly variable declarations guarantee the order in which the values are set?

    - by Jason Down
    Say I were to have a few readonly variables for filepaths, would I be able to guarantee the order in which the values are assigned based on the order of declaration? e.g. readonly string basepath = @"my\base\directory\location"; readonly string subpath1 = basepath + @"\abc\def"; readonly string subpath2 = basepath + @"\ghi\klm"; Is this a safe approach or is it possible that basepath may still be the default value for a string at the time subpath1 and subpath2 make a reference to the string? I realize I could probably guarantee the order by assigning the values in a constructor instead of at the time of declaration. However, I believe this approach wouldn't be possible if I needed to declare the variables inside of a static class (e.g. Program.cs for a console application, which has a static void Main() procedure instead of a constructor).

  • How to get this XmlAttribute

    - by user328738
    From the MusicBrainz REST service, I get the following xml: <artist-list offset="0" count="59"> <artist type="Person" id="xxxxx" ext:score="100"> ... Using WCF and XmlSerializationFormat, I'm able to get the type and id attributes... but How do I get the "ext:score" one? This works: public class Artist { [XmlAttribute("id")] public string ID { get; set; } [XmlAttribute("type")] public ArtistType Type { get; set; } But this doesnt: [XmlAttribute("ext:score")] public string Score { get; set; } It produces a serialization exception. I've also tried just using "score", but it doesn't work. Any help?

  • Java generics: What is the compiler's issue here? ("no unique maximal instance")

    - by Epaga
    I have the following methods: public <T> T fromJson( Reader jsonData, Class<T> clazz ) { return fromJson( jsonData, (Type)clazz ); } public <T> T fromJson( Reader jsonData, Type clazz ) { ... } The compiler is saying about the first method: type parameters of <T>T cannot be determined; no unique maximal instance exists for type variable T with upper bounds T,java.lang.Object return fromJson( jsonData, (Type)clazz ); ^ What is the problem?

  • What do I need to do to make sure my app launches as Admin?

    - by John Gietzen
    I'm writing an app that allows you to script the buttons from a wiimote into actions on your PC. It currently supports all of the features of the main remote control, except for the speaker. Now, I'm running in to trouble when I run it on Vista with UAC turned on. Any time a UAC'd window has focus, my app fails to move the mouse successfully. For instance, when an installer is run, I have to navigate it with the keyboard. Will running the app as administrator solve my problem? (At one point in time, I was able to successfully move the mouse over a UAC-password-entry box) How do I build a manifest that will tell windows to "run as administrator"? How do I embed this manifest into my app, if I'm strongly naming my assembly? How do I sign my application with an Authenticode cert? EDIT: Ok, so after some more extensive research, I have found: http://msdn.microsoft.com/en-us/library/bb756929.aspx <requestedExecutionLevel level="asInvoker|highestAvailable|requireAdministrator" uiAccess="true|false"/> However, the article says: Applications with the uiAccess flag set to true must be Authenticode signed to start properly. In addition, the application must reside in a protected location in the file system. \Program Files\ and \windows\system32\ are currently the two allowable protected locations. I have edited the question to reflect the new developments.

  • ASP.NET HTTPHandler not throwing exception when one is expected

    - by josephj1989
    I have an HttpHandler class (implements IHttphandler) where the path defined for the handler in web.config is *.jpg. I am requesting a Jpg image in my page. Within the HTTP Handler I am writing to a file in the filesystem. By mistake I was trying to write to a non existant directory. This should have thrown an exception but the execution simply proceeds.Ofcourse no file is written. But if I give a proper directory the file is written correctly.Is there anything special about HttpHandler Exceptions. See part of the code public void ProcessRequest(HttpContext context){ File.WriteAllLines(context.Request.ApplicationPath+@"\"+"resul.log",new string[]{"Entered JPG Handler"}); If I put a breakpoint on the File.WriteAllLines statement and then step over it I can see an exception occurring.

  • groovy closure parameters

    - by Don
    Hi, The following example of using the sendMail method provided by the grails mail plugin appears in this book. sendMail { to "[email protected]" subject "Registration Complete" body view:"/foo/bar", model:[user:new User()] } I understand that the code within {} is a closure that is passed to sendMail as a parameter. I also understand that to, subject and body are method calls. I'm trying to figure out what the code that implements the sendMail method would look like, and my best guess is something like this: MailService { String subject String recipient String view def model sendMail(closure) { closure.call() // Code to send the mail now that all the // various properties have been set } to(recipient) { this.recipient = recipient } subject(subject) { this.subject = subject; } body(view, model) { this.view = view this.model = model } } Is this reasonable, or am I missing something? In particular, are the methods invokedwithin the closure (to, subject, body), necessarily members of the same class as sendMail? Thanks, Don

  • PL/PGSQL function, having trouble accessing a returned result set from psycopg2...

    - by Paul
    I have this pl/pgsql function: CREATE OR REPLACE FUNCTION get_result(id integer) RETURNS SETOF my_table AS $ DECLARE result_set my_table%ROWTYPE; BEGIN IF id=0 THEN SELECT INTO result_set my_table_id, my_table_value FROM my_table; ELSE SELECT INTO result_set my_table_id, my_table_value FROM my_table WHERE my_table_id=id; END IF; RETURN; END; $ LANGUAGE plpgsql; I am trying to use this with Python's psycopg2 library. Here is the python code: import psycopg2 as pg conn = pg.connect(host='myhost', database='mydatabase', user='user', password='passwd') cur = conn.cursor() return cur.execute("SELECT * FROM get_result(0);") # returns NoneType However, if i just do the regular query, I get the correct set of rows back: ... return cur.execute("SELECT my_table_id, my_table_value FROM mytable;") # returns iterable result set Theres obviously something wrong with my pl/pgsql function, but I can't seem to get it right. I also tried using RETURN result_set; instead of just RETURN in the 10th line of my plpgsql function, but got an error from postgres.

  • Java: using endpoint to publish webservice to tomcat server

    - by Will
    hi all, i am creating a simple SOAP web service. i am to ensure that it runs on a tomcat web service. im trying to implement this with JAX-WS (see code) my question is: does the Endpoint.publish use the tomcat server to host this or is it a mini glassfish kind of server? should i be extending UnicastRemoveObject or something similiar instead? ideally it would be able to be packaged into a .WAR and dropped in the directory and just work. It doesn't seem to work with my installed tomcat server as is because it says the port is already in use. I'm using Ubuntu karmic with the tomcat6 package installed, it could also be my user doesnt have permissions to publish to the running tomcat on 8080 i hope this question is clear enough sample code: @WebService public class UserAttributes { public static void main(String[] args) { UserAttributes instance = new UserAttributes(); Endpoint.publish("http://localhost:8082/WebServices/userattributes", instance); } public string Hello() { return "Hello World"; } }

  • Is testability alone justification for dependency injection?

    - by fearofawhackplanet
    The advantages of DI, as far as I am aware, are: Reduced Dependencies More Reusable Code More Testable Code More Readable Code Say I have a repository, OrderRepository, which acts as a repository for an Order object generated through a Linq to Sql dbml. I can't make my orders repository generic as it performs mapping between the Linq Order entity and my own Order POCO domain class. Since the OrderRepository by necessity is dependent on a specific Linq to Sql DataContext, parameter passing of the DataContext can't really be said to make the code reuseable or reduce dependencies in any meaningful way. It also makes the code harder to read, as to instantiate the repository I now need to write new OrdersRepository(new MyLinqDataContext()) which additionally is contrary to the main purpose of the repository, that being to abstract/hide the existence of the DataContext from consuming code. So in general I think this would be a pretty horrible design, but it would give the benefit of facilitating unit testing. Is this enough justification? Or is there a third way? I'd be very interested in hearing opinions.

  • 0 not a valid FILE* when provided as a template argument

    - by Seva Alekseyev
    The following code #include <stdio.h> template <typename T, T v> class Tem { T t; Tem() { t = v; } }; typedef Tem<FILE*,NULL> TemFile; when compiled in a .mm file (Objective C++) by Xcode on MacOS X, throws the following error: error: could not convert template argument '0' to 'FILE*'. What's going on, please? The code in question compiled fine under MSVC. Since when is the 0 constant not a valid pointer to anything? Is this an artifact of Objective C++ (as opposed to vanilla C++)?

  • How to create a persistent connection using AS3 Sockets for a chat client

    - by Vivek
    I want to create a chat client in flash/flex for a chat server,something like a MUD/MOO client but I'm unable to create a persistent connection . I've been using the AS3 Socket class,but I'm getting disconnected from the server side,soon after the connection is made but the client still shows the 'connected' property as true .The server is asynchronous and was written in python using asyncore/asynchat, it works fine with most open source MOO/MUD clients . I tried connecting my program to a simple synchronous echo server,here both read and write worked fine with no disconnections from either side . So my question is how do I make a persistent connection with the server?

  • jQuery AJAX converting variable string to html styled text

    - by sadmicrowave
    I've got an AJAX transmission of a variable string in my primary coding language (Visual FoxPro 9) that looks like this: AjaxResponse = CREATEOBJECT("Custom") lcMessage = "<li class='hello'>Hello</li>" AjaxResponse.AddProperty("Reply", lcMessage) Response.ContentType = "text/html" Response.Write(AjaxResponse.Reply) While using the jQuery function .ajax() I've created a success: function that looks like this: $.ajax({ url: 'index?Proc=GetUuserHistory', dataType: "html", success: function(data){ $("div#history-text").text(data); }; }); My problem is that the text inserting into 'div#history-text' is unformatted and contains the li tags still. I've tried substituting the .text for .prepend, .append, and .html with no luck...is there a way to convert this string back to html format after its been received using Ajax?

  • Chrome Extension: How to display tab objects?

    - by Jalleluhah
    I am in the process of designing an extension for Google Chrome that helps to organize tabs (I know, there are many that already exist; that doesn't matter). I wish to open a popup window that will display tabs as objects (i.e., in the same way that it is displayed in the tab bar at the top of the browser). One way of doing this would be to pull various details (ID, Title, URL, etc.) from each tab, create a class and make instantiations of it upon the opening of each tab using these data, but this seems rather convoluted considering that what I want is sitting right there in the tab bar. Is there any simpler way to achieve this? In addition, I have seen several apps that utilize page previews. Is there something in the API that allows direct access to these?

  • are there java based auto-updating tools other than WebStart & Eclipse P2?

    - by DaddyB
    Hi, I am working on a java based application and we are looking to ease our deployment of updates. Up until now, we've always simply sent out new install packs & had the sysadmin's on our customer sites roll out the upgrades - painful for a large number of users. what I'd like to do is something similar to java webstart (or eclipse p2) - when the application starts, it checks for updates in a specified location and then downloads the updates prior to starting. But here's my problem - I want more control over what's done outside of the scope of plugins & jar files. For example: I'd like to be able to upate my JVM (we ship a modified version with additional security features). I need to install DLL's - possibly local to the jar files, sometimes to windows Occasiontally run MSI's to install windows components (e.g. printer drivers). I need to modify config files & the registry. I have found a few applications that support this (such as AppLifeUpdate at http://www.kineticjump.com/) but they tend to be .NET focused and it seems a bit perverse to introduce a .NET dependancy on a java application ;) I know I could write my own here, but if there is already a 3rd party library out there that supports this kind of facility, then it would make my life a lot easier. So, has anyone else had a similar problem & knows of some products I could look at? Thanks, Brian.

  • Loading an OverlayView from XIB -vs- programmatically for use with UIImagePickerController

    - by PLG
    I am currently making a camera app for iPhone and I have a strange phenomenon that I can't figure out. I would appreciate some help understanding. When recreating an overlay view for passing to UIImagePickerController, I have been successfully been able to create the view programmatically. What I haven't been able to do is create the view with/without controller in IB, load it and pass it to the overlay pointer successfully. If I do it via IB, the view is not opaque and obscures the view of the camera completely. I can not figure out why. I was thinking that the normal view pointer might be assigned when loading from XIB and therefore overwrite the camera's view, but I have an example programmatically where view and overlayView are set equal in the controller class. Perhaps the load order is overwriting a pointer? Help would be appreciated... kind regards.
