  • What type of data should I send to view?

    - by Vizualni
    Hello, this question I've been asking myself since the day I started programming in MVC way. Should I send to view arrays filled with data or should I send it as on objects I retrieved from database? My model returns me data as objects. What would be the best way to create such a thing? $new_data = $model->find_by_id(1); echo $new_data->name; $new_data->name= "whatever"; $new_data->save(); For example. view.php echo $object->name; or echo $array['name'] Language is php :).

  • How do i sort by: most viewed, most commented, most popular, best rating, etc?

    - by MrRioku
    Pretty basic question.. I kno.., I just don't know how its done. I see it everywhere. I want to be able to sort out my content in my websites by most viewed, most commented, most popular, best rating, etc...with a drop down list, check box, etc... but I don't know how "sort by" works? Which scripting language should it be written in? Javascript? PHP? Can it be done with XML? Do I have to have a database set up like MySQL? Is there a good tutorial anywhere that explains it? I need to be explained the exact process of how it works. As you can see I really need direction.. Your help is much appreciated :D

  • trying to understand some codes related to window.onload in js

    - by user2507818
    <body> <script language="javascript"> window.tdiff = []; fred = function(a,b){return a-b;}; window.onload = function(e){ console.log("window.onload", e, Date.now() ,window.tdiff, (window.tdiff[1] = Date.now()) && window.tdiff.reduce(fred) ); } </script> </body> Above code is taken from a site. In firefox-console, it shows: window.onload load 1372646227664 [undefined, 1372646227664] 1372646227664 Question: For window.tdiff->[undefined, 1372646227664], why not:[], because when runs to code:window.tdiff, it is still an empty array? For window.tdiff.reduce(fred)->1372646227664, window.tdiff = [undefined, 1372646227664], undefined - 1372646227664, should be NaN, why it shows 1372646227664?

  • What can we do to make XML processing faster?

    - by adpd
    We work on an internal corporate system that has a web front-end as one of its interfaces. The front-end (Java + Tomcat + Apache) communicates to the back-end (proprietary system written in a COBOL-like language) through SOAP web services. As a result, we pass large XML files back and forth. We believe that this architecture has a significant impact on performance due to the large overhead of XML transportation and parsing. Unfortunately, we are stuck with this architecture. How can we make this XML set-up more efficient? Any tips or techniques are greatly appreciated.

  • What are some good practice assignments for learning Java?

    - by HW
    Hello, I am a computer science in my Student Second year. I already know a good deal about C++, Data Structures, File Structures, OOP, etc. I decided to learn Java. I have read couple of books but I know that it takes practice to master any Programming language. I was wondering if anyone knew of some assignments or problems that helped them become good at programming. I am looking for something more challenging than "hello world"s and "3+2=5"s exercises. Thanks, ~HW

  • C++: String and unions

    - by sub
    I'm having a (design) problem: I'm building an interpreter and I need some storage for variables. There are basically two types of content a variable here can have: string or int. I'm using a simple class for the variables, all variables are then stored in a vector. However, as a variable can hold a number or a string, I don't want C++ to allocate both and consume memory for no reason. That's why I wanted to use unions: union { string StringValue; int IntValue; } However, strings don't work with unions. Is there any workaround so no memory gets eaten for no reason?

  • should a student be diversifying or mastering programming languages?

    - by Max Link
    As the question states, is it better if a student diversifies or explores when learning programming languages or should they focus only on 2-3 languages and really get to know them well? Example of what I mean by diversifying: Functional -> Scheme Procedural -> C Object Oriented -> Java Dynamic or scripting -> Python Other -> C++ I have a few breaks in between semesters sometimes (up to 3 months) and I'm thinking of either learning a new language or "master" those that I know right now. Which would benefit me in the future? I know some(about 3 months of self studying each) Java, C, and C++ already . If I'm not mistaken, where I live, the industry is heavy on Java, C++, and C#.

  • VB to c++ or c#?

    - by hilzmas
    I am trying to translate this code but I don't understand how to use the GET / PUT part of the code in another language like c++ or c#. This is the code : Private Sub cmd_Click() Dim i As Integer, a As Integer a = 10 For i = 1 To a Dim file As String Open "txt" For Binary As #1 file = Space(LOF(1)) Get #1, , file Close #1 Randomize Open "txtpath" & "\" & i & "txtname" For Binary As #1 Put #1, , file Put #1, , Rnd Close #1 Next i End Sub The code could have bug because I replaced variables with plain text. What I understand is that the code get a file and then save it with some random data added to make it look different than the original. I don't use vb since years and I don't remember anything about it. Can someone help me porting this snippet to c++ or c#?

  • is there any way to get country names from iPhone APIs?

    - by chiemekailo
    Hi, I want to provide a picker to the user to select a country. I've had a look in the NSLocale docs and I can get a list of all of the country codes supported on the device, which feels like a start: Code: NSArray *codes = [[NSArray alloc] initWithArray:[NSLocale ISOCountryCodes]]; But I can't work out if there is a programatic way to convert this array into country names... Ideally this list would be localized as well, i.e. show the country name in the user's preferred language. Can anyone point me in the right direction?

  • Shedule tasks question

    - by gabac
    Hi everyone I have a though question :) Let's say you get some data which is due at a certain point int the future. You get A saying my task is due in 1h and other which says his task is due in 1.5h. The information is collected on your server. In which programming language or even how would solve that? So task a will be executed in 1h, task B in 1.5h. I read something about java scheduler but I'm not yet sure if this is the right way. What are ur ideas? Cheers

  • jQuery plugin to style objects

    - by Alex
    Hi. I've been looking at the various JavaScript UI libraries and am wondering if there's one that can add some styling to page elements. I'm currently adding rounded corners, shadows, borders, and gradients via my own CSS + hacks to get it working on IE. I'm using jQuery for a number of tasks and wondered if there's a plugin that can add these design flairs more easily to DIVs. Not that you want to go overboard with this stuff, but when you need to use it, you'd like to depend on cross-browser and tried-and-tested solutions. Thanks.

  • require user to login in at login screen before giving access to iPhone app that accesses secure web

    - by MikeN
    On iPhone, how do I show a login screen to get username and password before giving access to iPhone app? Also, does the iPhone store a cookie to the secure website like a web browser? I was thinking of giving users to my website a long API key to store in the settings of their iPhone instead of asking them to login with a username/password (seems to be the Slicehost iPhone app approach.) Which is the best way to get a user to login securely? I have full control over the design of the iPhone app and website so have a lot of flexibility.

  • Delphi: what are the 8 mystery components on my form?

    - by mawg
    When I iterate of the controls on my form, I see those which I placed there at design time or run time. They are all of type TEdit, Tmemo, TComboBox, etc ... However, there are always exactly eight which I do not recognize. I can skip over them, since they are not of a type which interests me, but I am curios. I am guessing system controls like min/max/close. Their Name property is empty. Is there any way I can determine what type they are (without explicitly testing for every standard component derived from TWinControl) ? I am curious - but not yellow ;-)

  • Best way to put user input into generated javascript?

    - by Earlz
    Hello, I need for someone to be able to put some text into a page and then this gets sent to the server, saved in the database, and else where this text is put into a javascript variable. Basically like this: Write("var myVar=\""+MyData+"\";"); What is the best way of escaping this data? Is there anything out there already to deal with things like ' and " and new lines? Is base64 my only option? My serverside framework/language is ASP.Net/C#

  • Path of the local directory

    - by Jayesh
    Hi, A rather simple question; how to find the path of the local directory in which my exe is placed? As-in I have an .exe and in the program I have to create a txt file in the directory where the exe is! [language - C#] So, if the exe is in C:/Temp and is started from there; my txt should be created in C:/Temp If the user wishes to move the exe to D:/Temp and runs from there; I should be able to create the txt file in D:/Temp I tried the Directory.GetCurrentDirectory() but that returns the directory of the execution of the program!

  • Is it possible to Serialize and Deserialize objects in C++?

    - by GK
    As we know c++ is also an Object Oriented Programming language where most the things are objects like java. So wanted to know is the Serialize and deserializ features are available in c++ as well as we do it in java? If yes how it can be achieved? In java We use Serializable Interface to say that this type of object can be serialized and deserialized. So in c++ how? And out of curiosity is it same in c# as in java?

  • How do I use udev to find info about inserted video media (e.g. DVDs)

    - by Daniel
    I'm trying to port an application from using HAL to using pure udev. It is written in python and will use the gudev library, though I would love to see examples in any language. I'm able to get all attached video devices (such as cameras) via: import gudev client = gudev.Client(["video4linux"]) for device in client.get_devices(): print device.get_sysfs_attr("name"), device.get_device_name() This prints out something like: USB2.0 UVC WebCam /dev/video0 I am also able to get a list of block devices, but how can I: Tell if it is a CD/DVD drive? Tell if media is currently inserted if the drive supports removable media? Tell what the name/label of the media is (e.g. FUTURAMAS1 for a DVD)? The original code I am trying to port over is located at http://github.com/danielgtaylor/arista/blob/045a4d48ebfda44bc5d0609618ff795604ee134f/arista/inputs.py Any and all help would be greatly appreciated!

  • WCF: Is there a way to return an object that is able to execute on the server?

    - by mafutrct
    Coming from a Java background, this is the way I'm thinking: The server provides an object to the client. This object should be able to execute on the server. Server: private string _S = "A"; public interface IFoo { void Bar(); } private class Foo : IFoo { void Bar() { _S = "B";} } public IFoo GetFoo() { return new Foo(); } Client: IFoo foo = serverChannel.GetFoo(); foo.Bar(); Is this possible? Or is my understanding wrong and this is not how it works in WCF? What would be a better design?

  • What is the best way to start learning how to program?

    - by Joe K
    I'm very new to programming, but it has always interested me. I've tried to learn a couple of times except I don't know where to begin. What's a good language to learn first? What is a good website that can help me learn it? I once partitioned my hard drive and installed Ubuntu in an attempt to learn Python, but I was overwhelmed. I didn't know where to start or what to do. All suggestions, feedback, comments are welcome.

  • Omit attribute name from validation error message (at start of it)?

    - by mrbrdo
    I write code in English but I'm currently doing a site which is fully translated to another language (validation error messages included). However, I have a problem because validation error messages always seem to include the name of the attribute the error is on at the start of the error, e.g.: Title Prosimo izpolnite naziv fakultete. I want to get rid of the Title at the start, like so: Prosimo izpolnite naziv fakultete. Any help is appreciated. I would rather see if this can be solved without installing any 3rd party plugins. If it's possible to provide translations for attribute names, that would be a cool solution too, but I would still like to know how it can be done both ways (omit or translate).

  • OpenGL performance on rendering "virtual gallery" (textures)

    - by maticus
    I have a considerable (120-240) amount of 640x480 images that will be displayed as textured flat surfaces (4 vertex polygons) in a 3D environment. About 30-50% of them will be visible in a given frame. It is possible for them to crossover. Nothing else will be present in the environment. The question is - will the modern and/or few-years-old (lets say Radeon 9550) GPU cope with that, and what frame rate can I expect? I aim for 20FPS, but 30-40 would be nice. Would changing the resolution to 320x240 make it more probable to happen? I do not have any previous experience with performance issues of 3D graphics on modern GPUs, and unfortunately I must make a design choice. I don't want to waste time on doing something that couldn't have worked :-)

  • Successive success checks

    - by Stockhausen
    Most of you have probably bumped into a situation, where multiple things must be in check and in certain order before the application can proceed, for example in a very simple case of creating a listening socket (socket, bind, listen, accept etc.). There are at least two obvious ways (don't take this 100% verbatim): if (1st_ok) { if (2nd_ok) { ... or if (!1st_ok) { return; } if (!2nd_ok) { return; } ... Have you ever though of anything smarter, do you prefer one over the other of the above, or do you (if the language provides for it) use exceptions?

  • AS3 - Can I have access to the object (or function) who call me?

    - by lk
    I've asked this same question with Python. Now I like to know if this can be done in AS3. If I have something like this: package { public class SomeClass { private function A():void { C() } private function B():void { C() } private function C():void { // who is the caller, A or B ??? } public function SomeClass() { A() B() } } } Despite the design or other issues, this is only a question of an inquiring mind. Note: This has to be done without changing C signature Note 2: I like to have an access to an instance of the caller function so I can call that caller function (if I want to)

  • New datatype which can have numbers upto 100 digits.

    - by ckv
    Note: This was an interview question and may not have an actual use case currently The question was to design a class that can store numbers which are very very large say each number can have 100 digits. This new class is a datatype like int. What are the different types of constructors, overloads and other functions that you would write. How can this be further extended to support really large floating point numbers. How this can be given to others so that they can reuse the same component with their own additional functionality. My answer consisted of 2 approaches 1. using array of integers to store every say 10 digits 2. using string itself to store the number and perform operations on individual numbers. What would be the best approach?
