  • Call a non member function on an instance before is constructed.

    - by Tom
    Hi everyone. I'm writing a class, and this doubt came up. Is this undef. behaviour? On the other hand, I'm not sure its recommended, or if its a good practice. Is it one if I ensure no exceptions to be thrown in the init function? //c.h class C{ float vx,vy; friend void init(C& c); public: C(); }; //c.cpp C::C() { init(*this); } void init(C& c) //throws() to ensure no exceptions ? { c.vx = 0; c.vy = 0; } Thanks in advance

  • Why is the GUID structure declared the way it is?

    - by alabamasucks
    In rpc.h, the GUID structure is declared as follows: typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; BYTE Data[8]; } GUID; I understand Data1, Data2, and Data3. They define the first, second, and third sets of hex digits when writing out a GUID (XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXX). What I never understood was why the last 2 groups were declared together in the same byte array. Wouldn't this have made more sense (and been easier to code against)? typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; WORD Data4; BYTE Data5[6]; } GUID; Anyone know why it is declared this way?

  • Hashing and salting values

    - by Avanst
    I am developing a small web app that internally authenticates users. Once the user is authenticated my web app then passes some information such as userID and Person's name to a third party web application. The third party developer is suggesting that we hash and salt the values. Forgive my ignorance, but what exactly does that mean? I am writing the app in Java. So what I am planning on doing is hashing the userID, Person's name, and some Math.random() value as the salt with Apache Commons Digest Utils SHA512 and passing that hashed string along with the userID and person's name. Is that the standard practice? I should be passing the third party the salt as well correct?

  • What's the best way to do Ruby gemspec creation and dependency management?

    - by John Feminella
    Over the last few months, there have been a number of rapid developments in the state of Ruby dependency management and gem creation, to the point where I've been having trouble keeping up with everything. If I'm writing a new gem, what's the best tool for me to use to create my gemspec? Are there disadvantages of using this tool over competitors? I've used Bundler a few times on applications and for me it's been a lifesaver. Is the consensus that it is suitable for use with production apps? Are there quirks or idiosyncracies people should be aware of? Links to resources you've used and have found helpful would also be much appreciated.

  • What to use to write tests? [Rails]

    - by yuval
    I asked a question about different testing frameworks yesterday. This question can be found here. Now that I have a better understanding of the different frameworks, I have a very simple question: With a basic understanding, but very limited experience with writing tests with rails' built in testing framework (basic assertions), would it be okay for me to jump directly to testing with RSpec, Webrat, and Cucamber? Thank you! As a side note: yes, this is an opinion based question, but I feel that the input received to this question is valuable enough to the community to keep this question open. Thanks.

  • travesersing the dom with inexact parameters

    - by rashcroft23
    Hi, I want to grab the image src on a product page in a e commerce website. I'm writing this as a bookmarklet, so I'd like the code to work universally as possible. I've noticed that there are only two reoccurring factors in the product image tag among top e-commerce websites (amazon, bestbuy ect.): border=0 and 180<width&height<400. So how could I write a selector that would give me the srcof the first img element on the page with no border and width & height between 180 and 400 px? Or is there a better way of doing this? P.S. since I'm trying to keep the bookmarklet as light as possible, I don't want to use any libraries (jquery, yui etc)

  • Get the selected file in an Explorer window

    - by Jon Fournier
    I'd like to know how, if possible, to get the path of the selected file in an open Windows Explorer window. If not, would it at least be possible to get the folder path of an open Windows Explorer window? The end reason I'm doing this, is a software tool I'm writing requires a user to select a file. I figure if they're already moving the file around with Windows Explorer and then start my tool up, it'd be good not to have to make them navigate to the folder again in the file open dialog box. My software would then be able to identify if it's got the right file extension and if so, just ask the user if they want to import that file. Thanks.

  • Ruby Hash.merge with specified keys only

    - by ba
    I'm pretty sure I saw on a Rails related site something along the lines of: def my_function(*opts) opts.require_keys(:first, :second, :third) end And if one of the keys in require_keys weren't specified, or if there were keys that weren't specified, an exception was raised. I've been looking through ActiveSupport and I guess I might be looking for something like the inverse of except. I like to try and use as much of the framework as possible compared to writing my own code, that's the reason I'm asking when I know how to make the same functionality on my own. :) At the moment I'm doing it through the normal merge routine and making sure that I have what I need with some IFs.

  • how to not use relative links in html, but everytime starting from the domain.

    - by Andy
    Hi, I'm trying to make a page for use with wordpress and it's almost working, The page I want to use is an HTML page with designated space for it within certain DIVs. I'm encountering the problem of wordpress using the wrong links to kind of everything. I will probably have to change every link to http://www.mydomain.com/sub/folder/image.jpg while there are many links. the page is positioned in a subfolder, there where wordpress is installed on the server. But other pages are positioned in the root, and retrieve all other files directly starting from the domain so writing /sub/folder/image.jpg is enough. Is there a way I could get this to work with html/php files in sub folders as well (so when typing a link like /sub/folder/image.jpg they retrieve http://www.mydomain.com/sub/folder/image.jpg and not http://www.mydomain.com/sub/folder/sub/folder/image.jpg thanks!

  • Structure question over Local/Remote Services, Broadcast Receivers, and Intent Services

    - by Ryan
    I'm writing an android app that has a standard activity, but also needs to monitor incoming/outgoing calls and texts at all times. In addition, the app needs to notify users of information once a day without having the activity open. The information it notifies users of is stored in a database, so communication with the activity is not necessary. I've been researching for a week and still can't decide how to go about doing this. My instinct tells me I need a remote service that has a constantly running broadcast receiver, but every remote service example I see is overly complicated. Could anyone help me better understand what steps I need to take? Thanks in advance.

  • Constructors + Dependency Injection

    - by Sunny
    If I am writing up a class with more than 1 constructor parameter like: class A{ public A(Dependency1 d1, Dependency2 d2, ...){} } I usually create a "argument holder"-type of class like: class AArgs{ public Dependency1 d1 { get; private set; } public Dependency2 d2 { get; private set; } ... } and then: class A{ public A(AArgs args){} } Typically, using a DI-container I can configure the constructor for dependencies & resolve them & so there is minimum impact when the constructors need to change. Is this considered an anti-pattern and/or any arguments against doing this?

  • How to track when my application has unexpectedly shut down?

    - by Vilx-
    I'm writing an application whose purpose involves a lot of logging of different events. Among those I would also like to have an event that the application was shut down - even if unexpectedly like because of a power loss. Naturally, when the power goes out I don't get a chance to write anything anywhere. So my idea was to continuously write a timestamp in some known location (say, once per minute), and when the application was next run, it could determine the approximate time of the unexpected shutdown. A precision of 1 minute would be acceptable for me. However I'm worried that caching at the OS and disk level might interfere with this approach. Is there a better way or if not - how to make sure that the data I just wrote is REALLY written out to the physical medium? Added: Oh, almost forgot the buzzword line: Windows XP and above; .NET 3.5; C#.

  • Zoom controls not showing when using a MapView with fill_parent

    - by Joe
    Hey everyone I am working on an applications and I am using the built in zoom controls. When using a specific size I can see the zoom controls. When using fill_parent the zoom controls are not visible. How it is setup is a mapview inside of a frame layout(also using fill parent for the height and width but with an offset down the screen. The only thing I can think of is the fill parent issue is with the framelayout and the zoom controls are off the screen. Sorry if this is confusing, I confused myself writing it. Thanks in advance

  • How to trigger an event ONLY if both dropdowns are selected?

    - by DaveDev
    I have a dropdown select list on my page of class="TypeFilter". I have a jQuery event that fires when a value in that list is selected. $(".TypeFilter").change(function() { // Extract value from TypeFilter and update page accordingly )); I now have to add another list to the page, and I want to implement functionality which will prevent the .change(function() from running unless both are selected. In both lists the first option in the list is some text instructing the user to select one of the items, so I was thinking of just writing some logic to test that both lists have a selected index greater than 0. I think this is a touch unclean though, especially considering that other pages that have a TypeFilter use the same logic. Is there any nifty functionality in jQuery that can do this?

  • 2 different ways to define a widget in symfony, which to use?

    in the tutorial i can use either: public function configure() { $this->setWidgets(array( 'type' => new sfWidgetFormChoice(array( 'choices' => Doctrine_Core::getTable('Gender')->getTypesForForm(), 'expanded' => false, 'multiple' => false, )) )); $this->widgetSchema['type'] = new sfWidgetFormChoice(array( 'choices' => Doctrine_Core::getTable('Gender')->getTypesForForm(), 'expanded' => false, 'multiple' => false, )); } to define a widget. i wonder which i should use and why there is 2 ways of writing this? thanks

  • In python, how do I drag and drop 1 or more files onto my script as arguments with absolute path? (f

    - by chromejs10
    I am writing a simple Python script with no GUI. I want to be able to drag and drop multiple files onto my python script and have access to their absolute paths inside of the script. How do I do this in Mac, Linux, and windows? For times sake, just Mac will be fine for now. I've googled this question and only found one related one but it was too confusing. I am currently running Mac OS X Snow Leopard. Any help is much appreciated. Thanks!

  • How to access constant defined in child class from parent class functions?

    - by kavoir.com
    I saw this example from php.net: <?php class MyClass { const MY_CONST = "yonder"; public function __construct() { $c = get_class( $this ); echo $c::MY_CONST; } } class ChildClass extends MyClass { const MY_CONST = "bar"; } $x = new ChildClass(); // prints 'bar' $y = new MyClass(); // prints 'yonder' ?> But $c::MY_CONST is only recognized in version 5.3.0 or later. The class I'm writing may be distributed a lot. Basically, I have defined a constant in ChildClass and one of the functions in MyClass (father class) needs to use the constant. Any idea?

  • CI controller function is ignored

    - by den-javamaniac
    Hi. I'm trying to pass through a CI tutorial (writing a simple forum) and I can't make a controller function called. To be more specific I have this in a controller: function __construct() { parent::Controller(); $this->load->helper('url'); } function index() { $data['title'] = "Wlcome to Gossip"; $data['heading'] = "Welcome to Gossip"; $data['query'] = $this->db->get('topic')->result(); $this->load->view('welcome', $data); } function topic() { echo 'testing...'; } and when I'm trying to access the /index.php/forum/topic/ uri it just prints out my index() function. Can any one point out what may cause the problem?

  • End marker for command line arguments

    - by rwallace
    I'm writing a program which takes filenames and options on the command line in the usual way, and also can be directed to read arguments from a file. I'm implementing the semi-standard -- to turn off special treatment of subsequent arguments, and # as comment marker. I also want to implement a marker for 'disregard all arguments from here on', i.e. an end marker. Is there a common/semi-standard way to indicate this? Or, what way would people find least surprising?

  • Silently binding a variable instance to a class in C++?

    - by gct
    So I've got a plugin-based system I'm writing. Users can create a child class of a Plugin class and then it will be loaded at runtime and integrated with the rest of the system. When a Plugin is run from the system, it's run in the context of a group of plugins, which I call a Session. My problem is that inside the user plugins, two streaming classes called pf_ostream and pf_istream can be used to read/write data to the system. I'd like to bind the plugin instance's session variable to pf_ostream and pf_istream somehow so that when the user instantiates those classes, it's already bound to the session for them (basically I don't want them to see the session internals) I could just do this with a macro, wrapping a call to the constructor like: #define MAKE_OSTREAM = pf_ostream_int(this->session) But I thought there might be a better way. I looked at using a nested class inside Plugin wrapping pf_ostream but it appears nested classes don't get access to the enclosing classes variables in a closure sort of way. Does anyone know of a neat way to do this?

  • What do you do when you hate programming?

    - by Vimvq1987
    Don't know where to ask this question. It's likely to be closed, I know. I got a hard work. Tried to code, tried to search, tried to ask. Got nothing. It make me terribly tired, and some way, I feel that in this moment, I hate programming. Some said that hard works improve yourself, yes, but not impossible-works. Is there sometimes that you hate programming? Is there sometimes that you feel so tired of writing code? How do you overcome those times?

  • Why can't i call Contains method from my array?

    - by xbnevan
    Arrrg!I am running into what i feel is a dumb issue with a simple script i'm writing in powershell. I am invoking a sql command that is calling a stored proc, with the results i put it a array. The results look something like this: Status ProcessStartTime ProcessEndTime ------ ---------------- -------------- Expired May 22 2010 8:31PM May 22 2010 8:32PM What i'm trying to do is if($s.Contains("Expired")) , report failed. Simple...? :( Problem i'm running into is it looks like Contains method is not being loaded as i get an error like this: Method invocation failed because [System.Object[]] doesn't contain a method named 'Contains'. At line:1 char:12 + $s.Contains <<<< ("Expired") + CategoryInfo : InvalidOperation: (Contains:String) [], RuntimeException + FullyQualifiedErrorId : MethodNotFound So, what can i do to stop powershell from unrolling it to string? Actual ps script below - $s = @(Invoke-Sqlcmd -Query "USE DB GO exec Monitor_TEST_ps 'EXPORT_RUN',NULL,20 " ` -ServerInstance "testdb002\testdb_002") if ($s.Contains("Expired")) { Write-Host "Expired found, FAIL." } else { Write-Host "Not found, OK." }

  • What does "Only catch exceptions you can handle" really mean?

    - by KyleLib
    I'm tasked with writing an Exception Handling Strategy and Guidelines document for a .NET/C# project I'm working on. I'm having a tough go at it. There's plenty of information available for how/when to throw, catch, wrap exceptions, but I'm looking for describing what sorts of things should go on inside the catch block short of wrapping and throwing the exception. try { DoSomethingNotNice(); } catch (ExceptionICanHandle ex) { //Looking for examples of what people are doing in catch blocks //other than throw or wrapping the exception, and throwing. } Thanks in advance
