  • Scope of the Pages in a Silverlight application

    - by AngryHacker
    I have an app built with the Silverlight Navigation Application Template. I have a main form (e.g. MainPage.xaml) and a bunch of Silverlight Pages, which are swapped in and out of the main content area. In the MainPage.xaml, I have a DispatcherTimer which hits some Uri resources, regardless of which page I am on. Every now and then, it will inexplicably stop firing. I have an inkling that it has to do with the scope of various pages. Can pages inside the MainPage.xaml take away the scope from its parent? Or is this something much simpler?

  • validates_uniqueness_of...limiting scope - How do I restrict someone from creating a certain number

    - by bgadoci
    I have the following code: class Like < ActiveRecord::Base belongs_to :site validates_uniqueness_of :ip_address, :scope => [:site_id] end Which limits a person from "liking" a site more than one time based on a remote ip request. Essentially when someone "likes" a site, a record is created in the Likes table and I use a hidden field to request and pass their ip address to the :ip_address column in the like table. With the above code I am limiting the user to one "like" per their ip address. I would like to limit this to a certain number for instance 10. My initial thought was do something like this: validates_uniqueness_of :ip_address, :scope => [:site_id, :limit => 10] But that doesn't seem to work. Is there a simple syntax here that will allow me to do such a thing?

  • What did programmers do before variable scope, where everything is global?

    - by hydroparadise
    So, I am having to deal with seemingly archiac language (called PowerOn) where I have a main method, a few datatypes to define variables with, and has the ability to have sub-procedures (essentially void methods) that does not return a type nor accepts any arguements. The problem here is that EVERYTHING is global. I've read of these type of languages, but most books take the aproach "Ok, we use to use a horse and cariage, but now, here's a car so let's learn how to work on THAT!" We will NEVER relive those days". I have to admit, the mind is struggling to think outside of scope and extent. Well here I am. I am trying to figure out how to best manage nothing but global variables across several open methods. Yep, even iterators for for loops have to be defined globaly, which I find myself recycling in different parts of my code. My Question: for those that have this type experience, how did programmers deal with a large amount of variables in a global playing field? I have feeling it just became a mental juggling trick, but I would be interested to know if there were any known aproaches.

  • Getting around IBActions limited scope

    - by Septih
    Hello, I have an NSCollectionView and the view is an NSBox with a label and an NSButton. I want a double click or a click of the NSButton to tell the controller to perform an action with the represented object of the NSCollectionViewItem. The Item View is has been subclassed, the code is as follows: #import <Cocoa/Cocoa.h> #import "WizardItem.h" @interface WizardItemView : NSBox { id delegate; IBOutlet NSCollectionViewItem * viewItem; WizardItem * wizardItem; } @property(readwrite,retain) WizardItem * wizardItem; @property(readwrite,retain) id delegate; -(IBAction)start:(id)sender; @end #import "WizardItemView.h" @implementation WizardItemView @synthesize wizardItem, delegate; -(void)awakeFromNib { [self bind:@"wizardItem" toObject:viewItem withKeyPath:@"representedObject" options:nil]; } -(void)mouseDown:(NSEvent *)event { [super mouseDown:event]; if([event clickCount] > 1) { [delegate performAction:[wizardItem action]]; } } -(IBAction)start:(id)sender { [delegate performAction:[wizardItem action]]; } @end The problem I've run into is that as an IBAction, the only things in the scope of -start are the things that have been bound in IB, so delegate and viewItem. This means that I cannot get at the represented object to send it to the delegate. Is there a way around this limited scope or a better way or getting hold of the represented object? Thanks.

  • Theory: "Lexical Encoding"

    - by _ande_turner_
    I am using the term "Lexical Encoding" for my lack of a better one. A Word is arguably the fundamental unit of communication as opposed to a Letter. Unicode tries to assign a numeric value to each Letter of all known Alphabets. What is a Letter to one language, is a Glyph to another. Unicode 5.1 assigns more than 100,000 values to these Glyphs currently. Out of the approximately 180,000 Words being used in Modern English, it is said that with a vocabulary of about 2,000 Words, you should be able to converse in general terms. A "Lexical Encoding" would encode each Word not each Letter, and encapsulate them within a Sentence. // An simplified example of a "Lexical Encoding" String sentence = "How are you today?"; int[] sentence = { 93, 22, 14, 330, QUERY }; In this example each Token in the String was encoded as an Integer. The Encoding Scheme here simply assigned an int value based on generalised statistical ranking of word usage, and assigned a constant to the question mark. Ultimately, a Word has both a Spelling & Meaning though. Any "Lexical Encoding" would preserve the meaning and intent of the Sentence as a whole, and not be language specific. An English sentence would be encoded into "...language-neutral atomic elements of meaning ..." which could then be reconstituted into any language with a structured Syntactic Form and Grammatical Structure. What are other examples of "Lexical Encoding" techniques? If you were interested in where the word-usage statistics come from : http://www.wordcount.org

  • Extending WikiPlex with Scope Augmenters

    - by mhawley
    [In addition to blogging, I am also using Twitter. Follow me: @matthawley] Another extension point with WikiPlex is Scope Augmenters. Scope Augmenters allow you to post process the collection of scopes to further augment, or insert/remove, new scopes prior to being rendered. WikiPlex comes with 3 out-of-the-box Scope Augmenters that it uses for indentation, tables, and lists. For reference, I'll be explaining… (read more)

  • What follows after lexical analysis?

    - by madflame991
    I'm working on a toy compiler (for some simple language like PL/0) and I have my lexer up and running. At this point I should start working on building the parse tree, but before I start I was wondering: How much information can one gather from just the string of tokens? Here's what I gathered so far: One can already do syntax highlighting having only the list of tokens. Numbers and operators get coloured accordingly and keywords also. Autoformatting (indenting) should also be possible. How? Specify for each token type how many white spaces or new line characters should follow it. Also when you print tokens modify an alignment variable (when the code printer reads "{" increment the alignment variable by 1, and decrement by 1 for "}". Whenever it starts printing on a new line the code printer will align according to this alignment variable) In languages without nested subroutines one can get a complete list of subroutines and their signature. How? Just read what follows after the "procedure" or "function" keyword until you hit the first ")" (this should work fine in a Pascal language with no nested subroutines) In languages like Pascal you can even determine local variables and their types, as they are declared in a special place (ok, you can't handle initialization as well, but you can parse sequences like: "var a, b, c: integer") Detection of recursive functions may also be possible, or even a graph representation of which subroutine calls who. If one can identify the body of a function then one can also search if there are any mentions of other function's names. Gathering statistics about the code, like number of lines, instructions, subroutines EDIT: I clarified why I think some processes are possible. As I read comments and responses I realise that the answer depends very much on the language that I'm parsing.

  • askubuntu scope seems to lag

    - by Nkciy84
    I installed the askubuntu scope/lens in Ubuntu 12.04 LTS but it seems to be almost extremely laggy. Sometimes when I enter text in the searchfield it takes a (whole lot of) while before something is displayed underneath the icons in text. Usualy I just see the first letters of the text I put in. Like: "damn, why is this scope so slow" i see "find 'dam'" on ask ubuntu" This 'bug' makes the lens/scope/thing almost impossible to use for me.

  • ORACLE PL/Scope

    - by Yaakov Davis
    I didn't find much data about the internals of PL/Scope. I'd like to use it to analyze identifiers in PL/SQL scripts. Does it work only on Oracle 11g instances? Can I reference its dlls to use it on a machine with only ORACLE 9/10 installed? In a related manner, do I have to execute the script in order to its identifiers to be analyzed?

  • JS: I'm not getting the scope

    - by Manuel
    Hi there, I'm trying to modify CouchDB's JS API to work asynchronous, but there is an error I cannot solve: Please find my JS API find at pastebin. If I call (new CouchDB("dbname")).designDocs() (line 193) I get an error because the okCallback function is not defined in the callback function. I don't know why; it should be defined in this scope.. Any hints are very welcome! Cheers, Manuel

  • Implementing dynamic scope when using CPS as intermediate language

    - by asandroq
    I am currently studying the implementation of programming languages and became interested in using Continuation-Passing Style as the intermediate language of the compiler. I also want to implement limited dynamic scope (for exception-handling or Scheme parameter objects) but I cannot find the relevant literature. I think it can be done with a separate environment passed as a variable to every closure, but this solution seems ugly to me. Could anyone point me to the relevant literature, or give me an idea of how this can be done?

  • #Define's scope throughout library?

    - by Mohit Deshpande
    Say I have a constant: #define PI 3.14 Say I have a static library with multiple header and source files. If I declare this in the header file, will its scope apply to all of the source files? Or do the source files need to include the header with the declaration of PI?

  • getJSON and variable scope in javascript

    - by nillls
    Hi! In order to make function calls to our back-end php code we've implemented something called an ActionProxy like this: function ActionProxy(action, input, callback){ $.post("ActionProxy.php?method="+action, { data: input}, function(data, textStatus, XMLHttpRequest){ //return data.ResponseWhatever } }); The problem we're having is that using data outside the ActionProxy is impossible due to variable scope limitations (we assume), setting var res = data.ResponseWhatever or return data.ResponseWhatever is pretty futile. How would one handle these responses most appropriately so that functions calling the actionproxy can access the response values?

  • Scope of const char*

    - by Neeraj
    Consider this code: const char* someFun() { // ... some stuff return "Some text!!" } int main() { { // Block: A const char* retStr = someFun(); // use retStr } } My question is in the function sumFun() where is "some Text!!", stored (i think may be in some static area in ROM) and what will be its scope? Will the memory pointed by retStr be occupied throughout the program or be released once the block A exits? -- Thanks

  • Modifying a HTML page to fix several "bugs" add a function to next/previous on a option dropdown

    - by Dennis Sylvian
    SOF, I've got a few problems plaguing me at the moment and am wondering if anyone could assist me with them. I'm trying to get Next Class | Previous Class to act as buttons so that when Next Class is clicked it will go to the next item in the dropdown list and for previous it would go to back one. There used to be a scroll bar that allowed me to scroll the main window left and right, it's missing because (I think it was to do with the scroll left and scroll right function) The footer at the bottom doesn't show correctly on mobile devices; for some reason it appears completely differently to as it does on a computer. The "bar" practically and the Scroll Left and Scroll buttons don't appear at all on mobile devices. The scroll left button is unable to be clicked for some reason, I'm unsure what I've done wrong. Refreshing the page resets the horizontal scroll position to far left (I'm pretty sure this relates to the scroll bar) I want to also find a way so that on mobile devices the the header will not show the placeholder image, however I can't work out what CSS media tag(s) I should be using.

  • Strange behavior with Powershell scriptblock variable scope and modules, any suggestions?

    - by DanMan
    NOTE: I'm using PowerShell 2.0 on Windows Vista. I'm trying to add support for specifying build arguments to psake, but I've run into some strange PowerShell variable scoping behavior dealing specifically with calling functions that have been exported using Export-ModuleMember (which is how psake exposes it's main method). Following is a simple PowerShell module to illustrate (named repoCase.psm1): function Test { param( [Parameter(Position=0,Mandatory=0)] [scriptblock]$properties = {} ) $defaults = {$message = "Hello, world!"} Write-Host "Before running defaults, message is: $message" . $defaults #At this point, $message is correctly set to "Hellow, world!" Write-Host "Aftering running defaults, message is: $message" . $properties #At this point, I would expect $message to be set to whatever is passed in, #which in this case is "Hello from poperties!", but it isn't. Write-Host "Aftering running properties, message is: $message" } Export-ModuleMember -Function "Test" To test the module, run the following sequence of commands (be sure you're in the same directory as the repoCase.psm1): Import-Module .\repoCase.psm1 #Note that $message should be null Write-Host "Before execution - In global scope, message is: $message" Test -properties { "Executing properties, message is $message"; $message = "Hello from properties!"; } #Now $message is set to the value from the script block. The script block affected only the global scope. Write-Host "After execution - In global scope, message is: $message" Remove-Module repoCase The behavior I expected was for the script block I passed to Test to affect the local scope of Test. It is being 'dotsourced' in, so any changes it makes should be within the scope of the caller. However, that's not what's happening, it seems to be affecting the scope of where it was declared. Here's the output: Before execution - In global scope, message is: Before running defaults, message is: Aftering running defaults, message is: Hello, world! Executing properties, message is Aftering running properties, message is: Hello, world! After execution - In global scope, message is: Hello from properties! Interestingly, if I don't export Test as a module and instead just declare the function and invoke it, everything works just like I would expect it to. The script block affects only Test's scope, and does not modify the global scope. I'm not a PowerShell guru, but can someone explain this behavior to me?

  • UIView drawRect; class variables out of scope

    - by Toby Wilson
    Short & sweet version of my last question in light of new information. I have a UIVIew with an init and a drawrect method (and another thread and a bunch of other stuff, but I'll keep it short & sweet). All of the class variables that I alloc and init in the -(id)init method are out of scope/nil/0x0 in the drawRect method, and I am unable to access them. For example; In the interface: NSObject* fred; In the implementation: -(id)init { if(self == [super init]) { fred = [[NSObject alloc] init]; } return self; } -(void)drawRect:(CGRect)rect { NSLog(@"Fred is retained %i times",[fred retainCount]); //FAIL NSLog(@"But his variable is actually just pointing at uninitialised 0x0, so you're not reading this in the debugger because the application has crashed before it got here." } Should add that init IS being called before drawRect also. Anyone have any ideas?

  • spring.net application scope repository object on loadbalanced application

    - by Bert Vandamme
    Hi, We have an application running on a loadbalanced environment, let say webserver A and B. The loadbalancing is on the HTTP level, so the loadbalancer directs each user request to one of both webservers. The scope of the repositories in the application is managed by the spring.net container, and the application relies on data that can be cached by the repository (performance reasons). In this case we can never be sure that the cached data in the repositories on both webservers is the same. Is there mechanism in spring.net that can manage this kind problem? Or is there another common approach for this kind of thing? Any ideas? Thx, Bert

  • python decorator to modify variable in current scope

    - by AlexH
    Goal: Make a decorator which can modify the scope that it is used in. If it worked: class Blah(): # or perhaps class Blah(ParentClassWhichMakesThisPossible) def one(self): pass @decorated def two(self): pass Blah.decorated ["two"] Why? I essentially want to write classes which can maintain specific dictionaries of methods, so that I can retrieve lists of available methods of different types on a per class basis. errr..... I want to do this: class RuleClass(ParentClass): @rule def blah(self): pass @rule def kapow(self): pass def shazam(self): class OtherRuleClass(ParentClass): @rule def foo(self): pass def bar(self): pass RuleClass.rules.keys() ["blah", "kapow"] OtherRuleClass.rules.keys() ["foo"]

  • What is the scope of require_once in PHP?

    - by TMG
    Simple question: Is the scope of require_once global? For example: <?PHP require_once('baz.php'); // do some stuff foo ($bar); function foo($bar) { require_once('baz.php'); // do different stuff } ?> When foo is called, does it re-parse baz.php? Or does it rely on the already required file from the main php file (analagous to calling require_once twice consecutively for the same include file)? I saw this thread before, but it didn't quite answer the question: http://stackoverflow.com/questions/1669707/should-require-once-some-file-php-appear-anywhere-but-the-top-of-the-file Thanks for your help!

  • Limit scope of #define

    - by Ujjwal Singh
    What is the correct strategy to limit the scope of #define and avoid unwarrented token collisions. In the following configuration: Main.c # include "Utility_1.h" # include "Utility_2.h" VOID Utility() // Was written without knowing of: Utility_1 & Utility_2 { const UINT ZERO = 0; } VOID Main() { ... } // Collision; for Line:5 Compiler does not indicate what replaced Utility_1.h # define ZERO "Zero" # define ONE "One" BOOL Utility_1(); Utility_2.h # define ZERO '0' # define ONE '1' BOOL Utility_2(); Utility_2.c # include "Utility_2.h" BOOL Utility_2() { // Using: ZERO & ONE } //Collision: Character Literal replaced with String {Edit} Note: This is supposed to be a generic quesition so do not limit yourself to enum or other defined types. i.e. What to do when: I MUST USE #define Please comment on my proposed solution below.. _
