  • How to pass objects to functions in C++?

    - by Rakesh K
    I am new to C++ programming, but I have experience in Java. I need guidance on how to pass objects to functions in C++. Do I need to pass pointers, references, or non-pointer and non-reference values? I remember in Java there are no such issues since we pass just the variable that holds reference to the objects. It would be great if you could also explain where to use each of those options.

  • How to avoid nested functions when using AJAX?

    - by Fletcher Moore
    Sequential Asynchronous calls are gross. Is there a more readable solution? The problem is this is hard to follow: ajaxOne(function() { // do something ajaxTwo(function() { // do something ajaxThree() }); }); where the anonymous functions are callbacks that are called on server response. I'm using a third party API to make the AJAX calls, so I need a generic solution.

  • Defined variables and arrays vs functions in php

    - by Frank Presencia Fandos
    Introduction I have some sort of values that I might want to access several times each page is loaded. I can take two different approaches for accessing them but I'm not sure which one is 'better'. Three already implemented examples are several options for the Language, URI and displaying text that I describe here: Language Right now it is configured in this way: lang() is a function that returns different values depending on the argument. Example: lang("full") returns the current language, "English", while lang() returns the abbreviation of the current language, "en". There are many more options, like lang("select"), lang("selectact"), etc that return different things. The code is too long and irrelevant for the case so if anyone wants it just ask for it. Url The $Url array also returns different values depending on the request. The whole array is fully defined in the beginning of the page and used to get shorter but accurate links of the current page. Example: $Url['full'] would return "http://mypage.org/path/to/file.php?page=1" and $Url['file'] would return "file.php". It's useful for action="" within the forms and many other things. There are more values for $Url['folder'], $Url['file'], etc. Same thing about the code, if wanted, just request it. Text [You can skip this section] There's another array called $Text that is defined in the same way than $Url. The whole array is defined at the beginning, making a mysql call and defining all $Text[$i] for current page with a while loop. I'm not sure if this is more efficient than multiple calls for a single mysql cell. Example: $Text['54'] returns "This is just a test array!" which this could perfectly be implemented with a function like text(54). Question With the 3 examples you can see that I use different methods to do almost the same function (no pun intended), but I'm not sure which one should become the standard one for my code. I could create a function called url() and other called text() to output what I want. I think that working with functions in those cases is better, but I'm not sure why. So I'd really appreciate your opinions and advice. Should I mix arrays and functions in the way I described or should I just use funcions? Please, base your answer in this: The source needs to be readable and reusable by other developers Resource consumption (processing, time and memory). The shorter the code the better. The more you explain the reasons the better. Thank you PS, now I know the differences between $Url and $Uri.

  • Enable clipboard functions in swf generated by pdf2swf.

    - by user515
    I am using pdf2swf (http://www.swftools.org/) to convert PDF's to .swf. I have written a flex application that loads the swf generated by pdf2swf. I want to enable select , copy and paste functions on the loaded swf. Is there a way to do this. Please note I am able to extract the text from the loaded swf using textSnapshot, which means the pdf2swf does not convert the text to shapes.

  • Returning a private variable in JavaScript

    - by enrmarc
    I don't know why console.log(Set.current_index) shows 0 instead of 3. var Set = (function() { var set = []; var index = 0; function contains(set, e) { for (var i = 0; i < set.length; i++) { if (set[i] === e) { return true; } } return false; } var add = function(e) { if (!contains(set, e)) { set[index++] = e; } } var show = function() { for (var i = 0; i < set.length; i++) { console.log(set[i]); } } return { add: add, show: show, current_index: index }; })();? Set.add(20); Set.add(30); Set.add(40); Set.show(); console.log(Set.current_index);

  • Simultaneous private and public inheritance in C++

    - by gspr
    Suppose a class Y publicly inherits a class X. Is it possible for a class Z to privately inherit Y while publicly inheriting X? To make this clearer, suppose X defines public methods x1 and x2. Y inherits X, overrides x1 and provides a method y. Does C++ allow for a third class Z to subclass Y in such a way that Y's implementation of x1 and y are privately available to it, while the outside world only sees it inheriting X publicly, i.e. having only a single public method x2?

  • Adding procedural C openGL functions to an iPhone project

    - by user309595
    I want to add a few drawing functions to an iPhone project for drawing things. Something like drawTile(x,y,len,wid); which would call openGL to draw a box somewhere. I should just be able to write a procedural C file to do this but the openGL libraries are objective C and I'm getting weird errors. Do I have to make a class for all of my drawing commands and call class methods?

  • How do I assign functions in a dictionary?

    - by Ziv
    hi, I'm having a problem with a simple program I wrote, I want to perform a certain function according to the users input. I've already used a dictionary as a replacement for a switch to do assignment but when I try to assign functions to the dictionary it doesn't execute them... The code: def PrintValuesArea(): ## do this def PrintValuesLength(): ## do that def PrintValuesTime(): ## do third PrintTables={"a":PrintValuesArea,"l":PrintValuesLength,"t":PrintValuesTime} PrintTables.get(ans.lower()) ## ans is the user input what did I do wrong? It looks the same as all the examples I've seen....

  • Using functions and environments

    - by Eduardo Leoni
    Following the recent discussions here (e.g. 1, 2 ) I am now using environments in some of my code. My question is, how do I create functions that modify environments according to its arguments? For example: y <- new.env() with(y, x <- 1) f <- function(env,z) { with(env, x+z) } f(y,z=1) throws Error in eval(expr, envir, enclos) : object 'z' not found I am using environments to keep concurrently two sets of simulations apart (without refactoring my code, which I wrote for a single set of experiments).

  • private classes inside namespaces

    - by blacklion
    Is there a way to restrict access to a class from outside a namespace? What I want is to have a class that is only accessible to other classes inside the same namespace without having to put the namespace in it's own assembly. Is there a reason this is not possible in C#?

  • JavaScript Self Executing Functions - What's the Difference?

    - by modernzombie
    I am very familiar with self executing functions from working with jQuery. (function($) { /* do stuff */ })(jQuery); Today I was reading the backbone.js source and noticed that they do this: (function() { /* do stuff */ }).call(this); Is this achieving the same thing? Would the following 2 lines of code do the same thing? (function($) { /* do stuff */ })(jQuery); (function($) { /* do stuff */ }).call(jQuery);

  • iOS app private distribution and MDM

    - by Hippocrates
    We want to develop apps for a variety of separate clients for use on their iPads/iPhones. Right now we have a developer license and and provision UUIDs manually and distribute the app OTA via a web server. This limits us to 100 devices per license and leaves us paying for upkeep of the license. Some of our clients may also be interested in using an MDM software package. What is the best way for us to provision and push apps to many clients and more that 100 devices? Would each client need to pay for their own enterprise license? Any input is appreciated. Thanks.
