  • preventing selection on MKPointAnnotation

    - by Derek
    Is there a way to prevent an annotation in a MKMapView instance from being enabled. In other words, when the user taps the red pin on the map, is there a way to prevent it from highlighting the pin. Right now the pin turns dark when touched... Edit: I'm using the following code to return the MKPinAnnotationView // To future MKMapView users - Don't forget to set _mapView's delegate _mapView.delegate = self; _annotation = [[MKPointAnnotation alloc] init]; _annotation.coordinate = myLocation; [_mapView addAnnotation:_annotation]; -(MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation{ MKPinAnnotationView *pin = [[MKPinAnnotationView alloc] initWithAnnotation:_annotation reuseIdentifier:@"id"]; pin.enabled = NO; return pin; }

  • Badword filter in PHP?

    - by morpheous
    I am writing a badword filter in PHP. I have a list of badwords in an array and the method cleanse_text() is written like this: public static function cleanse_text($originalstring){ if (!self::$is_sorted) self::doSort(); return str_ireplace(self::$badwords, '****', $originalstring); } This works trivially, for exact matches, but I wanted to also censor words that have been disguised like 'ab*d' where 'abcd' is a bad word. This is proving to be a bit more difficult. Here are my questions: Is a badword filter worth bothering with (it is a site for professionals so a certain minimum decorum is required - I would have thought) Is it worth the hustle of trying to capture obvious work arounds like 'f*ck' - or should I not attempt to filter those out. Is there a better way of writing the cleanse_text() method above?

  • prevent conversion of <br/>

    - by Chris
    Hello, I fear this is a dumb question, but I can't seem to find the answer. Pretty sure what that makes me...... I have C# generated HTML (HtmlGenerator), to which I sometimes want to insert a line break at a certain part of a cell's innertext. Here is how that comes out: <TD >There are lots of extra &lt; br /&gt; words here </TD> This then displays the <br/> as a part of my cell text - not good. Am I missing an easy way to have the <br/> preserved and not converted to &lt, etc...? thanks

  • Inspiration and influence of the else clause of loop statements?

    - by Aristide
    Python offers an optional loop-else clause which is executed if and only if the loop is not terminated by a break. (In other words, the condition fails for a while-loop or the iterator is exhausted for a for-loop.) Does this loop-else construct originate from another language? (Either theoretical or actually implemented.) Has it been taken up in any newer language? Maybe I should ask the former of Guido, but surely he is too busy for such a futile inquiry. ;-) Related discussion and examples: Pythonic ways to use ‘else’ in a for loop

  • Is html/javascript equivalent to as3/flex?

    - by DJ.
    Hello my fellow coders, As i notice for a while now (like everybody else in the industry), the RIA market is shifting from AS3/Flex to HTML/Javascript. What i would like to know is? Is html/javascript as powerfull as as3/Flex or are they entirely different. With other words can i build the exact same applictions with HTML(4/5) and Javascript as i can do with AS3/Flex? I'm not looking for the speed comparison? or bashing one technology over the other? I just want to know if is good for me to dive into javascript, JQuery...... PS. If there is a nother post on stackoverflow with the exacte question. please share the link. Thanks. Thank you.

  • Loading HTML5 video on iPad via onclick event tied to a div

    - by joncys
    I'm developing an HTML5 application (a game), that automatically preloads 5 video files. I'm able to do so correctly on Safari for PC, so there are no overlooked problems with file formats, codecs or such. The load fails on an iPad. As an official guide for video on iOS puts it: This means the JavaScript play() and load() methods are also inactive until the user initiates playback, unless the play() or load() method is triggered by user action. In other words, a user-initiated Play button works, but an onLoad="play()" event does not. Does this mean, that I have no means to initiate the loading of video after a user initiated action, if that action hasn't been tied to a video element (user clicked on a regular div — I request loading and displaying of a video, compared to the user actually clicking on a video element to load and play that particular element)? Thanks for your help!

  • Regular Expression; Find whether a line contains any word with more than X characters.

    - by Simpsoid
    Hi, I am trying to use a Validator on a ASP.NET site and need to find whether the Street Address textbox contains a valid entry. Entries with words that are longer than X characters (in this case 25, with no punctuation or spaces) will cause the HTML on a printed A4 page to not wrap properly and therefore not to confrom to certain sizes correctly pushing the margins off. For a street address I want to match that something like "201 Long Road" is valid but "235 ReallyLongAndNarrowWindingRoadBesideTheRiver Street" is invalid. Using a Microsoft .Net Regular Expression Validator I need to know what the RegEx pattern might be. I think if it does find a match the Validator will fire correctly however if there is no match the Validator won't fire and the Update button (in this case) won't fire. Since Street addresses can contain Capital Letters and numbers etc. it will need to accomodate for that and also Spaces, Commas, Semi-Colons and Colons and Hyphens are valid characters too. Any help would be greatly appreciated as I am really stuck with this problem. Thanks, David

  • Arabic SQL query (on Oracle DB) returns empty result

    - by unprecedented
    I have this query (that runs on Oracle 10g database): SELECT ge.*, ge.concept AS glossarypivot FROM s_glossary_entries ge WHERE (ge.glossaryid = '161' OR ge.sourceglossaryid = '161') AND (ge.approved != 0 OR ge.userid = 361) AND concept = '?' ORDER BY ge.concept The query must display all words that begin with the arabic letter "?" but unfortunately, it returns empty result .. However, if I run the same query on the same database which runs on MYSQL, it works well and displays the correct result .. What should I do in order to get this query working the right way on oracle 10 database? P.S. the oracle database character set is : "AL32UTF8" thank you so much in advance

  • What alternatives are there to Google App Engine?

    - by Chris Marasti-Georg
    What alternatives are there to GAE, given that I already have a good bit of code working that I would like to keep. In other words, I'm digging python. However, my use case is more of a low number of requests, higher CPU usage type use case, and I'm worried that I may not be able to stay with App Engine forever. I have heard a lot of people talking about Amazon Web Services and other sorts of cloud providers, but I am having a hard time seeing where most of these other offerings provide the range of services (data querying, user authentication, automatic scaling) that App Engine provides. What are my options here?

  • Rails has_one vs belongs_to semantics

    - by Anurag
    I have a model representing a Content item that contains some images. The number of images are fixed as these image references are very specific to the content. For example, the Content model refers to the Image model twice (profile image, and background image). I am trying to avoid a generic has_many, and sticking to multiple has_one's. The current database structure looks like: contents - id:integer - integer:profile_image_id - integer:background_image_id images - integer:id - string:filename - integer:content_id I just can't figure out how to setup the associations correctly here. The Content model could contain two belongs_to references to an Image, but that doesn't seem semantically right cause ideally an image belongs to the content, or in other words, the content has two images. This is the best I could think of (by breaking the semantics): class Content belongs_to :profile_image, :class_name => 'Image', :foreign_key => 'profile_image_id' belongs_to :background_image, :class_name => 'Image', :foreign_key => 'background_image_id' end Am I way off, and there a better way to achieve this association?

  • how to turn off percentage sign in .net/wpf?

    - by Vitalik
    I would like my WPF application to display all percentages without % sign. For example 20% would be displayed as "20" but i still want to use the standard formatting for percentages (so i get the benefit of string formatter to multiply it by 100 for me) in other words, how do i get string.Format("0.00%", 0.2) to output "20" but not "20%"? Is it possible to globally define PercentSymbol as empty string for the entire application? In particular i am using ContentStringFormat in my WPF application to format the numbers and percentages. Maybe i can do it directly in WPF.

  • Transitioning from C++ to C#

    - by Jim
    I am very experienced in C and C++ but am having problems finding current opportunities. I decided to switch to C# but noticed that while the syntax is very similar, the programming styles are very different (we don't have IEnumerable etc in C). So the problem I am having now is having 20 years of experience but is only a junior when it comes to interviewing for a C# job. Most of the problems are me not being able to answer questions like 1) How do you do XYZ in Sql Server? 2) What's the use of in Spring.NET In other words, the phone interviewers don;t care if you know DB programming or not - they want to know if you know SQL Server. I am frustrated because the guys who are doing the interviews seem to be so narrow sighted in knowing ONLY C#, .NET and SQL Server, that I don't know how to get past them.

  • Is my way of doing threads in Android correct?

    - by Charlie
    Hi, I'm writing a live wallpaper, and I'm forking off two separate threads in my main wallpaper service. One updates, and the other draws. I was under the impression that once you call thread.start(), it took care of everything for you, but after some trial and error, it seems that if I want my update and draw threads to keep running, I have to manually keep calling their run() methods? In other words, instead of calling start() on both threads and forgetting, I have to manually set up a delayed handler event that calls thread.run() on both the update and draw threads every 16 milliseconds. Is this the correct way of having a long running thread? Also, to kill threads, I'm just setting them to be daemons, then nulling them out. Is this method ok? Most examples I see use some sort of join() / interrupt() in a while loop...I don't understand that one...

  • Drupal: FileFields... internal server error

    - by Patrick
    hi, I've moved my drupal installation to new server and the website works. HOwever I get an "internal server error" for each file field in my nodes. In other words, images and videos are not loaded. In Firebug, Net Tab I can see they cannot be retrieved from the server because of "internal server error". The only thing I changed with respect to the previous installation is commenting the following 2 lines in .htaccess # Don't show directory listings for URLs which map to a directory. #Options -Indexes # Follow symbolic links in this directory. #Options +FollowSymLinks Is this the issue ? How can I solve this ? thanks

  • Text to a PNG on App Engine (Python)

    - by Bemmu
    Note: I am cross-posting this from App Engine group because I got no answers there. As part of my site about Japan, I have a feature where the user can get a large PNG for use as desktop background that shows the user's name in Japanese. After switching my site hosting entirely to App Engine, I removed this particular feature because I could not find any way to render text to a PNG using the image API. In other words, how would you go about outputting an unicode string on top of an image of known dimensions (1024x768 for example), so that the text will be as large as possible horizontally, and centered vertically? Is there a way to do this is App Engine, or is there some external service besides App Engine that could make this easier for me, that you could recommend (besides running ImageMagick on your own server)?

  • Need help with formulating LINQ query

    - by eponymous23
    I'm building a word anagram program that uses a database which contains one simple table: Words --------------------- varchar(15) alphagram varchar(15) anagram (other fields omitted for brevity) An alphagram is the letters of a word arranged in alphabetical order. For example, the alphagram for OVERFLOW would be EFLOORVW. Every Alphagram in my database has one or more Anagrams. Here's a sample data dump of my table: Alphagram Anagram EINORST NORITES EINORST OESTRIN EINORST ORIENTS EINORST STONIER ADEINRT ANTIRED ADEINRT DETRAIN ADEINRT TRAINED I'm trying to build a LINQ query that would return a list of Alphagrams along with their associated Anagrams. Is this possible?

  • Relating categories with tags using SQL

    - by Pablo
    I want be able to find tags of items under the a certain category. Following is example of my database design: images +----------+-----+-------------+-----+ | image_id | ... | category_id | ... | +----------+-----+-------------+-----+ | 1 | ... | 11 | ... | +----------+-----+-------------+-----+ | 2 | ... | 12 | ... | +----------+-----+-------------+-----+ | 3 | ... | 11 | ... | +----------+-----+-------------+-----+ | 4 | ... | 11 | ... | +----------+-----+-------------+-----+ images_tags +----------+--------+ | image_id | tag_id | +----------+--------+ | 1 | 53 | +----------+--------+ | 3 | 54 | +----------+--------+ | 2 | 55 | +----------+--------+ | 1 | 56 | +----------+--------+ | 4 | 57 | +----------+--------+ tags and categories each have their own table relating the id to an actual name(text). So my question is how will i find out that images with category_id=11 have have the tag_id 53 54 55 56 57. In other words how to find the tags that images in certain category have?

  • How to decode U.P.S. Information from UPS MaxiCode Barcode?

    - by user46482
    I recently purchased a 2D Barcode reader. When scanning a U.P.S. barcode, I get about half of the information I want, and about half of it looks to be encrypted in some way. I have heard there is a UPS DLL. Example - Everything in bold seems to be encrypted, while the non-bold text contains valuable, legitimate data. [)01961163522424800031Z50978063UPSN12312307G:%"6*AH537&M9&QXP2E:)16(E&539R'64O In other words, this text seems OK - and I can parse the information [)01961163522424800031Z50978063UPSN123123 ... While, this data seems to be encrypted ... 07G:%"6*AH537&M9&QXP2E:)16(E&539R'64O Any Ideas???

  • What is a valid and reasonable alternative to a massive storage approach?

    - by Backo
    I am using Ruby on Rails 3.2.2 and MySQL. After my previous question on "how to handle massive storage of records in database for user authorization purposes", since related answers (on how to solve the issue or how to accomplish to that I am looking for) aren't sufficiently detailed or require to much resources (at least for me), I would like to know what are valid and reasonable alternatives to that approach. In few words, this question could be phrase as: how to handle "complex" (at level of SQL querying) user authorizations when you have to fetch "authorized" records? That is, for example, how to retrieve records when you would use code like the following (the following code would be used mostly in index controller actions): Article.readable_by_user(@current_user) # => Returns all articles readable by the current user.

  • In a C++ template, is it allowed to return an object with spesific type parameters?

    - by nieldw
    When I've got a template with certain type parameters, is it allowed for a function to return an object of this same template, but with different types? In other words, is the following allowed? template<class edgeDecor, class vertexDecor, bool dir> Graph<edgeDecor,int,dir> Graph<edgeDecor,vertexDecor,dir>::Dijkstra(vertex s, bool print = false) const { /* Construct new Graph with apropriate decorators */ Graph<edgeDecor,int,dir> span = new Graph<edgeDecor,int,dir>(); /* ... */ return span; }; If this is not allowed, how can I accomplish the same kind of thing?

  • Again: Android Stock browser vs. WebView?

    - by user2281606
    maybe a very easy question, but this drives me crazy... I work in company where we develope apps based on webviews. Everytime something went wrong, my boss tells me: "Hey look, the page runs nicely in the android browser, so it has to run that way in the app. Make it happen." I know that every manufacturer has his own implementation, discussed here: Android WebView VS Phone Browser But i want to keep my question simple: Is the android stock browser a pimped webview or in other words, extends the android browser from webview-class ? Thanks for any response?

  • Conditionally setting the font color of an item in a drop down box in JSF

    - by Greg
    I'm a newbie to web programming, so please bear with me. I am using JSF 1.2 and I want to conditionally set the color of the items in my drop down list. In other words, I have a collection of items that, along with a key and a value, also have a boolean property, warning, that is dynamically set by user action. I want the drop down to show all of the items, but those whose warning property is set to true should be displayed in red. I assume I have to extend the SelectItem class to add in the boolean property. How do I then conditionally set the color of the font of those items whose warning property is set to true in my JSP pages? Thanks in advance

  • Proper usage of Java Weak Reference in case of nested collections

    - by Tong Wang
    I need to define a weak reference Map, whose value is a Set. I use Google collections' MapMaker, like this: Map<Class<? extends Object>, Set<Foo>> map = new MapMaker().weakKeys().weakValues().makeMap(); So, for Set<Foo>, can I use a normal HashSet? Or, do I have to create a weak HashSet, like this: Collections.newSetFromMap(new WeakHashMap<Foo, Boolean>()); And why? Another question, the key of my map is Class objects, when will a Class object become weakly reachable? In other words, what is the lifetime of a Class object? Thanks.

  • VB.NET take each letter of a word and display in ListBox

  • Newbie SQL joining question: houses, refrigerators, and apples

    - by Philip Brocoum
    There are three tables in my database: apples, refrigerators, and houses. Each apple belongs to a refrigerator (it has a column that references the refrigerator that it's in), and each refrigerator belongs to a house. The problem is, each apple ALSO belongs to a house. I guess this isn't "normalized" or whatever, but it's the way it is. Obviously, each apple should belong to the house that its refrigerator belongs to. An apple can't be in two different places at once, after all. So, my question is this: what SQL statement will allow me to find all of the "bad apples" that for some reason incorrectly reference a different house than the refrigerator that they are supposedly in. In other words, I need to find the apples that contain contradictory information. I don't know if this is a "join" question or not, but I'm sure there's probably a very straightforward way of figuring this out. I just don't know what it is. Thanks for your help!
