  • jQuery .noconflict with prototype not working in (you guessed it) IE.

    - by Kyle Sevenoaks
    On my new customer page, I have successfully implemented a jQuery show/hide toggle alongside a Prototype script using jQuery's .noconflict. (Thanks to all for answers!) But as the world of the net is, IE's not playing ball. {literal} <script src="http://code.jquery.com/jquery-latest.js" type="text/javascript"> </script> <script type="text/javascript"> var $j = jQuery.noConflict(); $j(function() { $j("#button1").click(function() { $j("#show-hide").toggle("slow"); }); });? </script> {/literal} As you all must know by now, I'm just newly coming to all this jQuery stuff, so I have no idea what could cause it. Thanks for any help.

  • How to override virtual function in good style? [C++]

    - by Knowing me knowing you
    Hi, guys I know this question is very basic but I've met in few publications (websites, books) different style of override virtual function. What I mean is: if I have base class: class Base { public: virtual void f() = 0; }; in some publications I saw that to override this some authors would just say: void f(); and some would still repeat the virtual keyword before void. Which form of overwriting is in good style? Thank you for your answers.

  • How do i resolve method Overlapping in java/Processing [duplicate]

    - by user3718913
    This question already has an answer here: How do I compare strings in Java? 24 answers I have two methods/function in a class, called, Qestion1 and Question2, i want it in such a way that after the user has answered Question one correctly, the Question 2 method is called. Whenever i call the method 2, it displays both of them together instead exiting the first method first. Here's a dummy code to illustrate what i'm saying: void Question1() { String question="What is the capital of England?"; String Answer="London"; if(Answer=='London') { Question2(); } } void Question2() { String question="What is the capital of California?"; String Answer="Sacramento"; if(Answer=='Sacramento') { Question3(); } } Pls, this question is in no way related to that other question. Pls peruse the thread again.

  • templated class : accessing derived normal-class methods

    - by user1019129
    I have something like this : class Container1 { public: method1() { ... } } class Container2 { public: method1() { ... } } template<class C = Container1> class X : public C { public: using C::method1(); ..... X(string& str) : C(str) {}; X& other_method() { method1(); ...; } } My question is why I have to use "using C::method1()", to be able to access the method.. Most of answers I found is for the case where templated-class inhering templated-class. Normally they mention using "this-", but this does not seem to work in this case. Can I do something else shorter... Also I'm suspecting the other error I'm getting is related to the same problem : no match call for (X<Container1>) (<std::string&>)

  • What is the difference between "render a view" and send the response using the Response's method "sendResponse()"?

    - by Green
    I've asked a question about what is "rendering a view". Got some answers: Rendering a view means showing up a View eg html part to user or browser. and So by rendering a view, the MVC framework has handled the data in the controller and done the backend work in the model, and then sends that data to the View to be output to the user. and render just means to emit. To print. To echo. To write to some source (probably stdout). but don't understand then the difference between rendering a view and using the Response class to send the output to the user using its sendResponse() method. If render a view means to echo the output to the user then why sendResponse() exists and vise versa? sendResponse() exactly sends headers and after headers outputs the body. They solve the same tasks but differently? What is the difference?

  • Problems deleting cookies, won't unset (PHP).

    - by RemiX
    I've tried searching the php manual and internet on how to delete cookies and I've tried it the exact same way they all say: setcookie("name", '', 1); or setcookie("name", '', time()-3600); But when I check the cookies in the cookies dialog in Firefox, it's still there with the same value. I set this cookie using the following line: setcookie("name", $value, time() + 259200, $path); I found this question on stackoverflow: http://stackoverflow.com/questions/2497501/cookie-wont-unset, but none of the answers solved the problem. I also tried putting all paramaters in, like the author said, but it had no effect. Does anyone see the problem?

  • A server-side language to Learn

    - by Roth
    I'm a graphic designer, with experience in print design. In fact, I'm working on digital prepress since 4 years ago. I'm doing a course on web design right now, although I have been studying it on my own for a while, online. So, my question is, what kind of server-side language do I need to learn? I'm feel comfortable with HTML, CSS, and Javascript, even with preprocessors like SASS and LESS, but server-side scripting becomes a nightmare to me. So, what kind of language is necessary to learn? Any book or resource to that specific language? Thanks a lot for your answers.

  • How would you find the height of objects given an image?

    - by Ram Bhat
    Heyguys.. This isn't exactly a programming question exactly. I just want to know what your approach would be to a common problem in Digital image processing. Lets say you have an image of a a few trees in say jpg format. How would you go about finding the heights of each of these trees. The photo is the only input you have. I want to know the approaches you have not code. So it doesnt matter if your answers are vague, or non DIP-ish.

    I am a student at Middlesex Universtity, London studying Information Technology. I really love software development and I have taught myself how to write HTML + CSS, JavaScript (I use jQuery and AngularJS) and Java (I learnt this in school). I have developed few apps (a desktop app in Java and a mobile app with AngularJS and PhoneGap) I am looking at applying for a part-time programming job to develop myself. Are there part time jobs available for someone like me and are my skill set enough to get me a job? I understand this topic may not be ideal here but this is the only place I know can provide me answers. Thank you!

  • What exactly is GRASP's Controller about?

    - by devoured elysium
    What is the idea behind Grasp's Controller pattern? My current interpretation is that sometimes you want to achieve something that needs to use a couple of classes but none of those classes could or has access to the information needed to do it, so you create a new class that does the job, having references to all the needed classes(this is, could be the information expert). Is this a correct view of what Grasp's Controller is about? Generally when googling or SO'ing controller, I just get results about MVC's (and whatnot) which are topics that I don't understand about, so I'd like answers that don't assume I know ASP.NET's MVC or something :( Thanks

  • If you could remove one feature of php to help newbies what would it be?

    - by Chris
    If you could remove one feature from PHP so as to discourage, prevent or otherwise help stop newer programmers develop bad habits or practices, or, to stop them falling into traps that might hinder their development skills what would it be and why? Now, before the votes to close it's not as open-ended as you might think. I'm not asking purely what is the worst feature or what feature would you really like to remove purely arbitrarily. Yes, there may not be one correct answer but I suspect there will be many similar answers which will provide me with a good idea of things I might be doing wrong, even inadvertently.

  • Windows C++: LPCTSTR vs const TCHAR

    - by mrl33t
    In my application i'm declaring a string variable near the top of my code to define the name of my window class which I use in my calls to RegisterClassEx, CreateWindowEx etc.. Now, I know that an LPCTSTR is a typedef and will eventually follow down to a TCHAR (well a CHAR or WCHAR depending on whether UNICODE is defined), but I was wondering whether it would be better to use this: static LPCTSTR szWindowClass = TEXT("MyApp"); Or this: static const TCHAR szWindowClass[] = TEXT("MyApp"); I personally prefer the use of the LPCTSTR as coming from a JavaScript, PHP, C# background I never really considered declaring a string as an array of chars. But are there actually any advantages of using one over the other, or does it in fact not even make a difference as to which one I choose? Thank you, in advanced, for your answers.

  • How to break up a table holding 100mil+ number of records?

    - by Chiao
    We're currently storing answers for 52 predefined questions for our clients in our matchmaking site. we have over 30million unique users summing up for worst case of a 52x30million rows. Of these 52 questions, 11 are required and always answered. Our previous solution was to open an answer table for each question. This solution distributed our answer rows for faster insert/delete/update. But it also caused us an unconventional programming such as dynamically opening a table each time a question is added/updated, or removing an answer table if it was to be destroyed permanently. We want to come up with a better solution for our third version but could't get very far yet. Any ideas to accomplish this in any other, perhaps a more conventional, way?

  • how to use javascript to download a file on Chrome without Chrome auto renaming file to "download"? [duplicate]

    - by user3688566
    This question already has an answer here: Is there any way to specify a suggested filename when using data: URI? 11 answers I use javascript to generate a file and download. It seems that depending on the version of chrome, the download file names can be auto renamed to 'download'. is there a way to avoid it? this is my code: var link = document.createElement("a"); link.setAttribute("href", 'data:application/octet-stream,' + 'file content here'); link.setAttribute("download", 'file1.txt'); link.click(); This is not a duplicated question because i am using the latest chrome and the previously suggested hyperlink is exactly what i am using. I think chrome v34 works fine. but once my chrome autoupdated to v35, it went back to 'download' file name.

At the end of the test, the test-engine will evaluate the answers. If the student obtains more than 50% then he can unlock the next module. And his test score is printed using Crystal Reports and saved in teacher's database, against that student's record. Else, if his score is less than 50%, the test-engine will count the no. of attempts to clear the quiz & randomly generate another set of 20 questions from a file (from the teacher's database).

  • Apple in-app-purchase ALWAYS with 30 % for Apple?

    - by swalkner
    Hi all, I know that Apple keeps 30 % of the money I make with in-app-purchase. But does that always count? I mean, if there's a feature allowing the user to buy something with an SMS-message, is that allowed? If yes, does Apple also keep 30 % then? Or if I make a WebService-call with username/password and return something to the user then, is it possible to charge that call and keep the money for myself? I thougt that those are options which are not allowed, but there are some apps out there which exactly do it that way - are they only "lucky" and Apple didn't see that or is it allowed to sell services that way? Thanks a lot for your answers, Stefan

  • Remove() not working on new elements [duplicate]

    - by user3317470
    This question already has an answer here: In jQuery, how to attach events to dynamic html elements? 9 answers I'm making a simple to do list. It's mostly working and finished. When you click on list elements the object gets removed and you can create new list elements through the text input at the bottom. The only problem is the new list elements can't be removed when you click them for some reason. Here's the code: http://jsfiddle.net/dnhynh/7psqndwL/20/ $(document).ready(function(){ $("li").click(function(){ $(this).remove(); }); $("button").click(function(){ var entry = $("#entry").val(); $("<li></li>", { text: entry }).appendTo("#list ul"); $("#entry").val(""); }); });

  • Windows using the DNS suffix search list on all lookups, even valid FQDNs. How to stop this?

    - by RealityGone
    When doing DNS lookups (specifically using nslookup, for some reason most things are not effected) Windows XP Pro SP3 is using the DNS suffix search list for every single one. Even for fully qualified domain names. For example I lookup "www.microsoft.com" but windows actually asks for "www.microsoft.com.eondream.com" (eondream.com is my primary domain). Now I can fix the issue by removing the Primary DNS suffix, but it seems to me that the DNS suffix search list should be for short, invalid names (where dots=0 or something). I'm sure I have a misconfiguration somewhere in windows but I don't know where. I've changed every option I can think of or find. Below is the output of ipconfig /all and nslookup (with debug & db2 enabled). This is using a static IP & (internal) DNS server. C:\ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : frayedlogic Primary Dns Suffix . . . . . . . : eondream.com Node Type . . . . . . . . . . . . : Unknown IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : eondream.com Ethernet adapter Wireless Network Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Dell Wireless 1390 WLAN Mini-Card Physical Address. . . . . . . . . : 00-1B-FC-29-EB-6B Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 192.168.13.32 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.13.13 DNS Servers . . . . . . . . . . . : 192.168.19.19 C:\nslookup Default Server: shardik.eondream.com Address: 192.168.19.19 set debug set db2 www.microsoft.com Server: shardik.eondream.com Address: 192.168.19.19 ------------ Got answer: HEADER: opcode = QUERY, id = 2, rcode = NOERROR header flags: response, want recursion, recursion avail. questions = 1, answers = 1, authority records = 0, additional = 0 QUESTIONS: www.microsoft.com.eondream.com, type = A, class = IN ANSWERS: - www.microsoft.com.eondream.com internet address = 208.69.36.132 ttl = 0 (0 secs) ------------ Non-authoritative answer: Name: www.microsoft.com.eondream.com Address: 208.69.36.132 (Note: it resolves to that IP because I use the opendns service and that is their suggestion page or whatever you want to call it) If I am reading the nslookup output correctly then it is not a problem with my DNS server because windows is actually asking for the incorrect domain.

  • C# Java Objective-C need expert advices

    - by Kevino
    Which platform as the edge today in 2012 with the rise of cloud computing, mobile development and the revolution of HTML5/Javascript between J2EE, .Net framework and IOS Objective-C ??? I want to start learning 1 language between Java, C# and Objective-C and get back into programming after 14 years and I don't know which to choose I need expert advices... I already know a little C++ and I remember my concepts in example pointers arithmetic, class etc so I tend to prefer learning C# and Objective-C but I've been told by some experienced programmers that Windows 8 could flop and .Net could be going away slowly since C++ and Html5/Javascript could be king in mobile is that true ? and that C# is more advanced compared to Java with Linq/Lambda... but not truly as portable if we consider android, etc but Java as a lot going for him too Scala, Clojure, Groovy, JRuby, JPython etc etc so I am lost Please help me, and don't close this right away I really need help and expert advices thanks you very much ANSWER : ElYusubov : thanks for everything please continue with the answers/explanations I just did some native C++ in dos mode in 1998 before Cli and .Net I don't know the STL,Templates, Win32 or COM but I remember a little the concept of memory management and oop etc I already played around a little with C# 1.0 in 2002 but things changed a lot with linq and lambda... I am here because I talked with some experienced programmers and authors of some the best selling programming books like apress wrox and deitel and they told me a few things are likely to happen like .Net could be on his way out because of Html5/Javascript combo could kill xaml and C++ native apps on mobile dev will outperform them by a lot... Secondly ios and android are getting so popular that mobile dev is the future so Objective-C is very hard to ignore so why get tied down in Windows long term (.Net) compared to Java (android)... but again android is very fragmented, they also said Windows 8 RT will give you access to only a small part of the .Net framework... so that's what they think so I don't know which direction to choose I wanted to learn C# & .Net but what if it die off or Windows 8 flop Windows Phone marketshare really can't compare to ios... so I'll be stuck that's why I worry is Java safer long term or more versatile if you want 'cause of the support for android ??
