  • is "Object();" a predefined function in javascript?

    - by Qlidnaque
    I come across code such as "personObj=new Object();" where a new object called personObj is being defined. What I'm trying to find out is whether Object() is a prefined function in javascript, because I understand by using the mentioned code, a instance of a class is being formed but in the example code where I'm studying from, the class Object() is not being defined anywhere, so I was wondering if Object() was a predefined function in javascript and whether I can be directed to some online resources, as all that shows up in google when I try to find Object() are articles in general javascript object oriented programming.

  • Explanation of NSMutableURLRequest : setHTTPMethod

    - by kkmoslehpour
    I am new to objective c programming. I am currently trying to insert data into mysql database. I have read a couple links on this and could not find the exact answer I am looking for. Here is what I am trying to do: I have my app that user inputs a name in a text field and once the press the add button, it makes a connection to my php file and my php file does the rest of the work (using POST method) and adds the name to the mysql dataase. I have seen a lot of people use NSMutableURLRequest : setHTTPMethod :POST`` in their code (in my case my php file does that and I don't haveNSMutableURLRequest` included in my code and it works perfectly fine.) My questions are: Are there any benefits of including NSMutableURLRequest in your code when you can just call your php code to take care of the POST for you? What does NSMutableURLRequest exactly do and which way is more efficient?

  • Google App Engine & Django Sandbox: Shell and Web seem to be using different datastores?

    - by tones
    I'm new to both Django and Google App Engine, and am using a sandbox in OSX10.6 with the GoogleAppEngineLauncher. I've got a basic "bookstore" application running from the tutorial in the OReilly "Programming Google App Engine" book. Here's the bug: If I add a new object to the datastore through the web interface, then it's readable through the web interface, but does not appear to exist if I query the datastore through the shell. Vice versa: If I add an object in the shell, then I can read it from the shell, but it doesn't appear in the web interface. Any thoughts or theories would be welcome. Thanks! =T=

  • sql connection problem only from another computer

    - by geoff
    I have a task that runs nightly. It connects to a sql server on our network and when I run it from my machine it runs fine. When it runs from the other computer I get the following error. System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) I've checked with our systems admin and he said nothing has changed on the sql box or on the box in question so I'm not sure why it runs fine from one and not the other. From what I've read about this error it sounds like it's a setting on the sql server that would disallow it to run on either box.

  • C++ - Where do i start?

    - by richzilla
    Hi All, As a bit of a side project while I'm on my summer break from uni, I've decided to have a look at C++, and get the hang of the basics. I'm by no means a programming novice, I've done web development before with PHP and Ruby, and I've done a fair bit of work with compiled languages (Java / C#). However, C++ seems to be a more significant undertaking. Basically I'm wanting pointers to the best resources for learning C++, as well as some idea as to areas I could do with reading up on (That I might not have come across before). Any help would be hugely appreciated. Thanks

  • download a complete folder

    - by Christian
    Hi, in my app I use several png-graphics. For the present version they are installed with the app in the folder "graphic". I made while programming. Now I need some more png-graphics and I don't want to make each time an app-update. How can I manage it, that the app is downloading the png-files from my webserver without knowing the name. I am looking for something which compares the files on the webserver with the files on the iPhone and if there is a new (or newer) file download it. Or is it possible to make an plist-file with the graphics??

  • selecting all text within a div on a single left click with javascript

    - by tstyle
    I have a simple non-clickable link within a div that looks like this: It's meant to be a sharable link that the user can copy paste into other things. For usability purposes, I want a single left click anywhere within the div to select the entire link: I don't know much about, javascript/web programming, so I've tried the following: <div id="share_link" onClick="select_all('share_link')"><%= request.url %></div> and this javascript <script type="text/javascript"> function select_all(id) { document.getElementById(id).focus(); } </script> This doesn't work. I'd like to know what's the simplest thing I should do to achieve what I want. I thought about changing the div to a text input or the text within to be a link, but ideally the content within should be read-only, non-editable, and non-clickable

  • Can I include a view in Kohana 3 that is not within `application/views`?

    - by alex
    I am building a staff area for a website, which is completely different to the main brochure style site. I have 2 Kohana systems setup. I realise they can both share the same system and modules folder. Now, with the second one, I want to make the main template view a view in a different folder. I tried this in my base controller $this->template = DOCROOT . '../~new2/application/views/template.php'; But Kohana is looking for it in its own views folder as evident by the error I received. I even put a var_dump(file_exists($this->template)); // true to be sure it was finding the correct file. Is there a way to add a template file that is not within the views folder, without hacking the core Kohana code (and if I'm lucky not extending and overloading the view class).

  • Is Artificial Intelligence a mature discipline?

    - by Lynxiayel
    I'm designing some AI games recently. And this question that is AI a mature discipline suddenly came to my mind. My own view is that AI is not mature yet. But there're exact theory systems here in AI already, including the expert system or knowledge presenting and so on. So it becomes a problem for me that I can't convince myself about whether it's mature or not with fully demonstration. Anyone has idea about this question? Show me your proof please. Thanks a lot for your attention and help.

  • Beginning Programmer Interested in Android - Should I Start with Java?

    - by Hudey
    I'm a beginner in programming. My experience so far is only in Actionscript 2 and 3. So I have a basic understanding of declaring variables, loops, arrays, if/then, do/while... I'm wanting to move to developing for Android phones so I'm wondering what suggestions people have for where to go next. Should I jump right to Android? Start with a 'beginning Java' approach? Or should I go some other route to beef up my knowledge of OOP concepts before launching into Android? I have my Dev environment set up and completed the Hello Android tutorial and I'm just wondering if I am going to be in over my head quickly?

  • Looking to redo a static website

    - by moorecats
    I have been asked to help redo my non-profit website. I would like to make it look better. What would be the best way to do this? I have some technical background and can learn. I have looked at various options such as Joomla, word press and so on but I am not certain on how to create a good UI for it. I have also looked at Ruby and such, which I think may be overkill for a static page such as this. I haven't done any programming etc in a few years, but I figure this may be an opportunity to get back into it.

  • SEO on a login based website

    - by Paul
    Ok so say I have a website that the majority of content is behind a closed door, login screen for paying customers only. How can I let google know what is there so people can find the site through a search engine. What programming techniques could I use to give more content to the google bot. I will have some overview and demonstration screens to tempt the users but will these five to ten pages of content be enough for the search engines. The key work is quite a highly sort one and there is quite alot of competition. And before anyone asks the site is not a subscription porn site (Sadly)

  • Artificial Intelligence - What to put in, or leave out, and what can be inferred?

    - by D Scott
    I was having a discussion with a coworker (while we were programming) about AI. We were talking about emotions/feelings and if you should choose to leave any out. I asked him, "Would you leave out racism or hate?" and if you did leave those out, what, if any, other emotions might lead to the AI learning the left out emotions or feelings. Should you PROGRAM in measures to stop the AI from learning those feelings? If you teach Love, does it need to know hurt? Or would it learn hurt? If it then knew Hurt would it connect it with Dislike, Hurt and Dislike could that then lead to some other non-programmed emotion? Such as hate? All while tele-commuting from home.

  • Running Java Server Application 24/7 (NOT on local machine) ...?

    - by Steven
    I am currently experimenting with Java Socket Programming and succeeded in creating a simple application that allows me to send data back and forth between a client and a server. I don't want to power my laptop (on which the server application runs) 24/7. Therefore, of course, no computer (that runs my client application) will be able to communicate with my selfmade server application as long as my laptop is turned off. Now I'd like to know: (1) Is it possible to run the server application on a remote (physical) server, so that I don't need my laptop for that purpose? (2) If yes, do you have any suggestions where I could rent such a remote server? As I said, I'm just curious about how all that stuff works. I don't really something expensive.

  • ValidateRect vs BeginPaint

    - by Armentage
    From the MSDN documentation: The BeginPaint function validates the entire client area. The ValidateRect function should not be called if a portion of the update region must be validated before the next WM_PAINT message is generated.1 I've been programming with Win32 API for years, and I've never thought to call the ValidateRect function. A co-worker of mine today pointed that we were missing a call to ValidateRect, which fixed a bug we were having doing some high-speed animation using GDI (I know, an oxymoron) Can someone tell me whether or not a call to ValidateRect is neccessary after a BeginPaint/EndPaint pair? I have seen no documentation at MSDN that sheds light on this, and what documentation and examples I do see that you do not need to.

  • Can I reproduce Scala's behavior for == ?

    - by JPP
    In Programming in Scala, I can read that the == operator behaves as if it was defined like this: final def == (that: Any): Boolean = if (null eq this) {null eq that} else {this equals that} But there must actually be compiler magic to avoid null pointer exceptions, right? Is there any way for me to replicate this behavior with pure Scala; i.e., have an operator/method return one thing if the receiver is null and another one if it isn't? What I mean is an actual implementation of null eq this. I suppose I can write a "pimp" and then define the method on the wrapper class, but is there a more direct way to do this?

  • WebGL on older Mac OS X versions (say 10.4)

    - by rotoglup
    Not really a programming related question but... I'd like very much to experiment with WebGL on my spare time. My current 'spare time' machine is a MacBook running Mac OS X Tiger (10.4.xx) and I'm unable to find a new browser supporting this OS. Firefox dropped support, Chrome too, and Safari idem. I read somewhere that this is due to a Quicktime bug that Apple won't fix. Does anyone have more information on this issue ? Does anyone have a clue or track to find a running implementation of WebGL on Mac OS X 10.4 ? Cheers,

  • [ADVICE] .NET Desktop Application - Client Server C#, SQL

    - by Rillanon
    Hi guys, Recently I've being given a chance to develop a PMS (Practice Management System) software for a small physiotherapy clinic. I'm a computer science student and my course is predominately told on Linux. However, my client runs all their computers on vista or Windows 7. My ideas are to develop the client front end in Visual C# and access a central postgresql server. I'm a beginner in Windows Programming so I'm after advice on best practice on implement user rights and access levels in C# (WPF or Windows FORM). I've had a look into Credential class in Visual C# and access control list but please share your thoughts. I'm probably way over my head on this but this is my first commercial project so I'm keen to test the waters. Cheers Ian

  • WIN32 visual c++

    - by mrbuxley
    I would like to write a simple program in c++. After the program is done i would like to get my answers in form of a graph or picture that would give some certain information if i click on a certain area. i have only written console apllications in c++ before and don't really have a clue where to start with the graphic part of it all. Can I write the first part of the program in console mode and some how run it under the WIN32 later? for ex what will happen to the cout<<"foo"; commands? Is there a simpler approach to do some very basic graphic programming.

  • Many-to-Many Relationship (with properties) in Google App Engine for Java

    - by rvandervort
    I understand from the official documentation on unowned relationships that the app must use sets of Key objects on either side of the relationship. This makes perfect sense. Coming from many years of RDBM-style programming, though, I'm pretty confused about how I can model properties of that relationship itself. For example, if I have entities Category and Entry in my many-to-many relationship and would like to persist a dateAdded property, or some other data that are only relevant when both sides of the relationship are known. I suppose it would be possible to create a third class : CategoryEntry that links the two, but this seems like a kludge. What is the proposed way to model this kind of situation ?

  • Mathematica quickie: About making cells Input cells by default.

    - by andrz
    I'm going through some lecture notes, Fundamentals of Mathematica Programming (see the .nb file there). I'd like to be able to do the exercises right there in the notebook; but for some reason I can't figure out how to make the default cell an Input cell. In other words, when I'm clicking in that notebook to create a new cell--in the exercises--the cell is by default a text cell. I'd like for it to be an Input cell so that I don't have to manually change it each time. Ideas?

  • Writing different structs to a file in C++? [on hold]

    - by user58053
    I need a way to write structures of three different kinds to a binary file, which later has to be searched. (As in, for example, struct A has two fields, an int and a char; struct B has int and a long; I need to output all structures whose int equals the one given from keyboard). I understand how to write structs of the same kind to a file and how to search them, but here I am just lost, best thing I came up with is declaring a struct containing all possibly needed fields and leaving the ones I don't need empty, but it really feels wrong, there HAS to be a better way to do that. I've read about binary files and could not find anything relevant, most examples and tutorials deal with writing one data type. Could anyone point me in the right direction? EDIT: I am looking for what @Jerry_coffin called database mode, and will probably use one of the existing database systems for that, best way to go, probably. Thank you everybody for the suggestions

  • Client to server data upload

    - by RickBowden
    I'm trying to design a system similar to the traditional server monitoring systems like MOM, Tivoli, Open View, where an agent will record data and then upload it to a central database once a day, but them also be able to send immediate alerts back to the server. I'm not sure what the best methodology might be for this. I've started looking at Microsoft sync services but I'm not sure if it will fit my needs. I'm using VS2008 and C#. Does anyone have any experience or ideas about how I should go about this task?
