  • Elegantly Handle Repetitive Property Code in C#

    - by Eric J.
    The language shortcut public string Code { get; set; } saves a bit of typing when defining trivial properties in C#. However, I find myself writing highly repetitive, not-quite-as-trivial property code that still follows a clear pattern e.g. public string Code { get { return code; } set { if (code != value) { code = value; NotifyPropertyChanged("Code"); } } } I can certainly define a Visual Studio snippet to reduce typing. However, if I need to add something to my pattern, I have to go back and change quite a bit of existing code. Is there a more elegant approach? Is a snippet the best way to go?

  • Which messaging services can BlackBerry apps integrate with?

    - by humble coffee
    I'm in charge of having a BlackBerry app developed that translates the contents of a message from one language to another. So the aim would be to have a button at the bottom of a received message which says 'translate this'. I've heard that this kind of thing is possible using J2ME plus the native BlackBerry API. Can this be done for all kinds of messanging features on the Blackberry, or just some? ie I'm thinking SMS, email and BB messages. Secondly, given that the translation itself is done via a web request, I feel like this should be a fairly lightweight application. Would anyone care to hazard a guess how long it might take an experienced contractor to develop such an app?

  • android localization: Is it a good practice to have only needed resource to put in localized folder?

    - by MobileDev123
    Hi, My application has 4 languages in it. However only one module needs to be localized out of 5, This module has 4 layout files and some images, remaining files can be there in default layout folder and drawable folders. My question is : is it good practice to put only needed files in localization folders, if I leave other files in its respective folders and don't copy them in translation folders, does my application throw NullPointerException when my application runs in other language? and Does android market have any size limit? (Also being a BB developer,AFAIK they do not allow OTA, if the application size grows more than 3 mb) [In case i need to copy the layout and image files]. Note about NullPointerException : it throws in string if you omit some string in localization and application runs in that particular locale. Thanks

  • Best way to convert between [Char] and [Word8]?

    - by cmars232
    I'm new to Haskell and I'm trying to use a pure SHA1 implementation in my app (Data.Digest.Pure.SHA) with a JSON library (AttoJSON). AttoJSON uses Data.ByteString.Char8 bytestrings, SHA uses Data.ByteString.Lazy bytestrings, and some of my string literals in my app are [Char]. This article seems to indicate this is something still being worked out in the Haskell language/Prelude: http // hackage.haskell.org/trac/haskell-prime/wiki/CharAsUnicode And this one lists a few libraries but its a couple years old: http //blog.kfish.org/2007/10/survey-haskell-unicode-support.html [Links broken because SO doesn't trust me -- whatever...] What is the current best way to convert between these types, and what are some of the tradeoffs? I don't want to pick something that is obsolete... Thanks!

  • Recommended place for pre-translated Zend Framework resources

    - by Exception e
    Since zf 1.10 Zend Framework ships with pre-translated validation messages. They are outside the library path. The manual illustrates how to load these in your bootstrap. $translator = new Zend_Translate( 'array', '/resources/languages', $language, array('scan' => Zend_Locale::LOCALE_DIRECTORY) ); Zend_Validate_Abstract::setDefaultTranslator($translator); I am inclined to think that these resources are specific to the zf-version; validators could change over time. If i copy the resources to my application tree I need to perform additional maintenance each time I upgrade to a newer version. What is best practice? Is there a ZF convention already?

  • When machine code is generated from a program how does it translates to hardware level operations ??

    - by user553492
    Like if say the instruction is something like 100010101 1010101 01010101 011101010101. Now how is this translating to an actual job of deleting something from memory? Memory consists of actual physical transistors the HOLD data. What causes them to lose that data is some external signal? I want to know how that signal is generated. Like how some binary numbers change the state of a physical transistor. Is there a level beyond machine code that isn't explicitly visible to a programmer? I have heard of microcode that handle code at hardware level, even below assembly language. But still I pretty much don't understand. Thanks!

  • Detect at runtime which country's App Store my iPhone app was downloaded from?

    - by Mike McMaster
    I have a feature in my iPhone application that, for business reasons, should only be shown/available to customers in the US. If I want to release this app to App Stores outside the US, what's the best way to figure out which country I'm in without relying on user-defined settings such as language and locale? In my mind, the ideal solution is that there's some runtime property that can tell me which App Store country the app was downloaded from, and I can take action accordingly. Looking through the docs and searching the web, I'm not coming up with anything in this department. I don't expect the solution to be 100% foolproof as far as users not being in the country they say they're from, but as close as possible would be nice. I suppose one solution would be to make a separate build for a new product on the App Store and have two versions, one for the US and one for the others, but that doesn't seem ideal. I'm hoping it can be the same product on the App Store to prevent things like fragmentation of user reviews. Thanks in advance!

  • Accessing object's method within string

    - by Wild One
    Recently I was reading php documentation and found interesting note in string section: Functions, method calls, static class variables, and class constants inside {$} work since PHP 5. However, the value accessed will be interpreted as the name of a variable in the scope in which the string is defined. Using single curly braces ({}) will not work for accessing the return values of functions or methods or the values of class constants or static class variables. See www.php.net/manual/en/language.types.string.php It says, that I can't use curly syntax to get value returned by object's method call. Is it a mistake in manual or I misunderstood it, because I tried the following code and it works just fine: <?php class HelloWorld { public static function hello() { echo 'hello'; } } $a = new HelloWorld(); echo "{$a->hello()} world";

  • How can I use "IF statements" in a postgres trigger

    - by Dan B
    I have a trigger function that I only want to fire on certain instances of INSERTS, in this case, if do_backup = true. If it fires in all instances, I get an infinite loop. The logic seems pretty simple to me, and the rest of the function works. But the trigger function does not seem to register my conditional and always runs, even when backup = true. CREATE OR REPLACE FUNCTION table_styles_backup() RETURNS TRIGGER AS $table_styles_backup$ DECLARE ... do_backup boolean; BEGIN SELECT backup INTO do_backup FROM table_details WHERE id=NEW.table_meta_id; IF (do_backup = true) THEN ... INSERT INTO table_styles_versions ( ... ) VALUES ( ... ); END IF; RETURN NULL; END; $table_styles_backup$ LANGUAGE plpgsql; CREATE TRIGGER table_styles_backup AFTER INSERT ON table_styles FOR EACH ROW EXECUTE PROCEDURE table_styles_backup();

  • How Can I Implement This In Java?

    - by davit-datuashvili
    first of all i am doing programs in java language this code is merely taken from web site i have not question about divide and conqurer algorithms but about function and it's argument here is code of ternary search def ternarySearch(f, left, right, absolutePrecision): #left and right are the current bounds; the maximum is between them if (right - left) < absolutePrecision: return (left + right)/2 leftThird = (2*left + right)/3 rightThird = (left + 2*right)/3 if f(leftThird) < f(rightThird): return ternarySearch(f, leftThird, right, absolutePrecision) return ternarySearch(f, left, rightThird, absolutePrecision) i am not asking once again how implement it in java i am asking for example how define function?for example let y=x^+3 yes we can determine it as public static int y(int x){ return x*x+3; } but here return ternarySearch(f, leftThird, right, absolutePrecision) function f does not have argument and how do such?please help me

  • need help revising this javascript that opens to a new window on submit/post

    - by Brad
    I have a form that once you select from a drop-down list and select submit, it is suppose to open up to a new window Here is the code that is currently on the page and I think it needs to be completely wiped out or revised, it only works in IE and Firefox <SCRIPT LANGUAGE="JavaScript" TYPE="text/javascript"> //<!-- Hide JavaScript from older browsers // Function to open a window function windowOpen(window_url) { helpWin = window.open(window_url,'','toolbar=yes,status=no,scrollbars=yes,menubar=yes,resizable=yes,directories=no,location=no,width=350,height=400'); if (document.images) { if (helpWin) helpWin.focus() } } // End script hiding --> </SCRIPT>

  • Generate all the ways to intersperse a list of lists, keeping each list in order.

    - by dreeves
    Given a list of lists like this [[1,2,3],[a,b,c,d],[x,y]] generate all permutations of the flattened list, [1,2,3,a,b,c,d,x,y], such that the elements of each sublist occur in the same order. For example, this one is okay [a,1,b,2,x,y,3,c,d] but this one is not [y,1,2,3,a,b,c,x,d] because y must occur after x, that being how x and y are ordered in the original sublist. I believe the number of such lists is determined by the multinomial coefficient. I.e., if there are k sublists, n_i is the length of the ith sublist, and n is the sum of the n_i's then the number of such permutations is n!/(n_i! * ... * n_k!). The question is how to generate those sublists. Pseudocode is great. An actual implementation in your language of choice is even better!

  • Ignoring (serious) errors to keep the program alive?

    - by SQuirreL bites
    One of the main things I wanted to achieve in my experimental programming language was: When errors occur (Syntax, Name, Type, etc.) keep the program running, no matter how serious or devastating it is. I know that this is probably very bad, but I just wanted something that doesn't kill itself on every error - I find it interesting what happens when a serious error occurs but the program continues. Does this "paradigm" have a name? I mean expect for How bad is it to do the above? Are there programs in use out there that just follow: "Hey, this is a fatal, unexpected error - but you know what? I don't care!"?

  • PHP and C# communication with Encrypt/Decrypt

    - by SilentWarrior
    Hello, I have been searching and cant find a consistent solution to my problem : I want to encrypt something in C# and decrypt it in PHP but also be able to encrypt in PHP and decrypt in C#, using the same key on both ends. All the solutions I found dont seem to work both ways, most of them only work on one language and then fail on the other, either by decrypting wrong or by blowing up the offsets. I would like to use TripleDES but it isnt a requirement, just want something relatively strong for plain text communication (will either use JSON or just plain key-value pairs for complex stuff). Thanks in advance PS: http://pastie.org/643106 this is what I have been testing with.

  • Why are configuration arrays acceptible parameters in PHP and Javascript?

    - by RenderIn
    In most other OO languages it would be sacrilege to have each function receive a single associative array of Objects rather than enumerating each in the method signature. Why is it acceptable and commonly used in most popular frameworks for both of these languages to do this? Is there some justification beyond wishing to have concise method signatures? I do see a benefit in this -- that the API could remain unchanged as new, optional parameters are added. But Javascript and PHP already allow for optional parameters in their method signatures. If anything, it seems like Java or another OO language would benefit from this more... and yet I rarely see this pattern there. What gives?

  • Determining child count of path

    - by sqlnewbie
    I have a table whose 'path' column has values and I would like to update the table's 'child_count' column so that I get the following output. path | child_count --------+------------- | 5 /a | 3 /a/a | 0 /a/b | 1 /a/b/c | 0 /b | 0 My present solution - which is way too inefficient - uses a stored procedure as follows: CREATE FUNCTION child_count() RETURNS VOID AS $$ DECLARE parent VARCHAR; BEGIN FOR parent IN SELECT path FROM my_table LOOP DECLARE tokens VARCHAR[] := REGEXP_SPLIT_TO_ARRAY(parent, '/'); str VARCHAR := ''; BEGIN FOR i IN 2..ARRAY_LENGTH(tokens, 1) LOOP UPDATE my_table SET child_count = child_count + 1 WHERE path = str; str := str || '/' || tokens[i]; END LOOP; END; END LOOP; END; $$ LANGUAGE plpgsql; Anyone knows of a single UPDATE statement that does the same thing?

  • Web Designer looking to learn back-end programming...

    - by Tabetha Moe
    Hello, my name is Tabetha and I have a question... I am a web designer, but I always find that while designing the layout and coding the design I come up with great ideas for websites. I would like to know where I need to start in order to learn back-end programming not only for the knowledge, but also for the challenge of it. I have searched online but can't seem to find the information I am looking for. If anyone can give me a simple, straight-forward "this is what language you need to learn" answer, or perhaps guide me in the right direction I would appreciate it ten-fold. I am a complete noob when it comes to this, so even the most basic information is probably a pearl of wisdom for me. :)

  • PHP: form input field names containing square brackets like field[index]

    - by gidireich
    Hi, I've seen lot of code that handle forms, which creates input fields with names containing square brackets. I understand that this is being somehow converted to PHP arrays when a PHP script examines the $_POST variable. My questions about this: What is the mechanism behind? At which point this names that merely contain brackets are converted to arrays? Is this a feature of the HTPP protocol? Of web servers? Of the PHP language? Continuing the previous question, is this a commonly used hack or a normal programming tool? What are (all) the rules of using brackets in input field names? Can multidimensional arrays be created this way? Thanks, Gidi
