  • How do I "step over" jQuery code while debugging?

    - by Scott Rippey
    While stepping through a script that uses jQuery, I just want to test the code I wrote. I don't want to step into the jQuery file -- I'm not debugging jQuery, just my own file. Are there any ways to tell a debugger to not step into the jQuery file? I use Visual Studio + Internet Explorer, as well as Firefox + Firebug for stepping through code ... and both seem to love to step through dozens of jQuery statements. For example, say I have a script like this: $("div").each(function() { $(this).hide(); }); I would like to press "step into" and not see the implementation of ".each()" etc... In C#, this is possible by using the [DebuggerStepThrough()] attribute on a class. But that doesn't help with JavaScript.

  • Can I work with Visual Studio Project and Solution files in a team using Subversion?

    - by flyx
    We're a team of students doing a software project. As some of us don't use Windows, but the product needs to run on Windows and .NET, we want to develop on MonoDevelop and Visual Studio which both use Visual Studio files; language of choice is C#. My question is: Can we check in the solution and project files into our repository without the possibility of severe conflicting problems? Example: Two guys add a new file to the same project, save and commit their changes. Will the project file get a conflict?

  • Call function by pointer and set parametrs in memory block

    - by Ellesmess Glain
    Hi, I've little problem : I'm solving problem with calling function by pointer and passing to it parameters in continuous memory block. My goal is to have function named e.g CallFunc(void * func,void *params, unsigned int param_length); that I'll send function pointer, pointer to function's parameters and eventually parameters length and this calling function will call passed function with it's parameters. I will like write this in C/C++, but if somebody has idea, how this resolve in other language, that supports DLL generation and exportet functions, it will be fine too. Thanks for answers, Ellesmess P.S. I'm sorry about my English, but I'm Czech, thanks :o)

  • Parsing through Arabic / RTL text from left to right

    - by Dan W
    Let's say I have a string in an RTL language such as Arabic with some English chucked in: string s = "Test:?????;?????;?????;a;b" Notice there are semicolons in the string. When I use the Split command like string[] spl = s.Split(';');, then some of the strings are saved in reverse order. This is what happens: ??Test:????? ????? ????? a b The above is out of order compared to the original. Instead, I expect to get this: ?Test: ????? ????? ????? a b I'm prepared to write my own split function. However, the chars in the string also parse in reverse order, so I'm back to square one. I just want to go through each character as it's shown on the screen.

  • Does this singleton pattern make sense?

    - by dontWatchMyProfile
    @implementation MySingletonClass static MySingletonClass *sharedInstance = nil; + (MySingletonClass*)sharedInstance { @synchronized(self) { if (sharedInstance == nil) { sharedInstance = [[self alloc] init]; } } return sharedInstance; } + (id)alloc { @synchronized(self) { if (sharedInstance == nil) { sharedInstance = [super alloc]; return sharedInstance; } } return nil; } + (id)allocWithZone:(NSZone *)zone { @synchronized(self) { if (sharedInstance == nil) { sharedInstance = [super allocWithZone:zone]; return sharedInstance; } } return nil; } -(id)init { self = [super init]; if (self != nil) { // initialize stuff here } return self; } @end Not sure if it's ok to overwrite both alloc and allocWithZone: like this...?

  • Optimal diff between object lists in Java

    - by Philipp
    I have a List of Java objects on my server which is sent to the client through some serialization mechanism. Once in a while the List of objects gets updated on the server, that is, some objects get added, some get deleted and others just change their place in the List. I want to update the List on the client side as well, but send the least possible data. Especially, I don't want to resend Objects which are already available on the client. Is there a library available which will produce some sort of diff from the two lists, so that I can only send the difference and the new Objects accross the wire? I have found several Java implementation of the unix diff command, but this algorithm is unpractical for order changes. ie. [A,B,C] - [C,B,A] could be sent as only place changes [1-3] [3-1], while diff will want to resend the whole A and C objects (as far as I understand).

  • Feed char array into stdin

    - by Brian Lindsey
    I am writing a parser for a mini scripting language. Some of my grammar rules require jumping to a different location in the file to obtain information. There doesn't seem to be a straightforward way to accomplish this. So, I was thinking about loading my data files into a char array array and parsing line by line. This will allow me to jump all over the array with ease. My question is, is it possible to feed char arrays (i.e. char *) into stdin, so I can easily invoke the yyparse() function as needed.

  • Can I distort a bitmap image in Flash?

    - by drpepper
    Hi, what I would like to do is to take a loaded GIF file as a Bitmap, and then distort it by stretching and shrinking parts of it, so it would look like it got squished up against the screen. I'm pretty sure that there's no easy way in Flash to go beyond scaling and shearing, but I wonder if there might be some simple techniques to accomplish this kind of effect. By the way, I've also thought of pre-deforming the images in GIMP and saving them there, but I can't find a simple way to do it without learning their scripting language. Thanks for your help!

  • Iframe no scrollbar?

    - by NebNeb
    I cant seem to show the scrollbar in my iframe. I am making a script that will rotate a page 180 degrees and it uses iframes. With this code it showed no scrollbar. <iframe frameborder="0" id="browser" src="http://google.com/"></iframe> It loads dynamically(although this is after a button is pressed) but this doesnt change anything. <script language="javascript"> function refresh() { document.getElementById("browser").src = document.getElementById("url").value; document.getElementById("browser").style.visibility="visible"; } function hide() { window.location = "?hide&url="+document.getElementById("url").value; } </script>

  • Advanced Registry Monitoring

    - by RyanTimmons91
    I'm attempting to create a small utility to watch for the creation (or modification) of a specific registry key, and to kill the process responsible for causing that registry modification. I have had success in watching the changes to the registry via a class called 'RegistryMonitor', however it does not give you any information on what process initiated the registry call, through some googling I found that a library called 'EasyHook' should be able to do what I want, but all the documentation states that its designed for a per-application hook. The program itself is a temporary security patch, until our vendors come out with an official security update. As best I can tell there isn't a way to do exactly what I want to accomplish from C#, which is the only language I can comfortable write, test and execute software in. Any help on this would be appreciated I'm considering watching the registry changes via the program I already have, then if the change is discovered (the pc is already infected) running RKill and locking down the PC to prevent the issue from getting any worse

  • How is this problem usually solved without using sever-side scripting?

    - by cyggi
    Simple problem I have so far always solved via PHP: You have a site with header, menu, footer and content field. Header, menu and footer are usually the same for each page. How do you, without PHP or any other server-side language, have the header, menu and footer data exist only in one file? So that for example you don't have ten sites (like home.html, products.html, about.html, ..) all having a copy of the static header and menu in their html files. Now if you want to change the header you have to change ten files. I hope I made my question clear enough, if not please leave a comment :)

  • c# class design - what can I use instead of "static abstract"?

    - by Ryan
    I want to do the following public abstract class MyAbstractClass { public static abstract int MagicId { get; } public static void DoSomeMagic() { // Need to get the MagicId value defined in the concrete implementation } } public class MyConcreteClass : MyAbstractClass { public static override int MagicId { get { return 123; } } } However I can't because you can't have static abstract members. I understand why I can't do this - any recommendations for a design that will achieve much the same result? (For clarity - what I am trying to do is provide a library with an abstract base class but the concrete versions MUST implement a few properties/methods themselves and yes, there are good reasons for keeping it static.)

  • 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?

  • Searching in a TreeMap (Java)

    - by Kronen
    I need to do a search in a map of maps and return the keys this element belong. I think this implementation is very slow, can you help me to optimize it?. I need to use TreeSet and I can't use contains because they use compareTo, and equals/compareTo pair are implemented in an incompatible way and I can't change that. (sorry my bad english) Map m = new TreeSet(); public String getKeys(Element element) { for(Entry e : m.entrySet()) { mapSubKey = e.getValue(); for(Entry e2 : mapSubKey.entrySet()) { setElements = e2.getValue(); for(Element elem : setElements) if(elem.equals(element)) return "Key: " + e.getKey() + " SubKey: " + e2.getKey(); } } }

  • Approaches to a week long camp programming course (tips & projects)

    - by Good Person
    I will be teaching a week long programming course to kids between the ages of 11-18. Most of the kids have no programming experience. I'm looking for two things 1) General tips for teaching a camp class (how to make it fun when explaining the difference between int and float) 2) Interesting projects that the kids will be able to complete by the end of the week. Unfortunately the language I'll be required to use is either c++ or Java which means that I'll need to spend more time on itty bitty details than I'd like in a week long course. I feel more competent in c++ than in Java. However if someone can show me that Java is much easier to learn I'll probably teach that instead. My initial idea is to try something like "a game a day" with games like hangman, tic-tac-toe, guess-a-number, wheel-of-fortune, etc. I'll try and update the question text as answers come in to offer more details While there are other questions about teaching programming around I'm looking for advice and tasks that are useful for specifically a week long camp

  • Are there alternative ways to implementing an "active link" navigation without using server side languages?

    - by Mel
    By "active" I mean to have the link pointing to the current page classed as "active." This way the link's appearance can be modified using css. Is it possible to implement an active link navigation without using a server side language? I would like to only use CSS/HTML/jQuery if possible. If there are, what are those methods? Assuming you want to create the following structure: <ul id="nav"> <li class="active">Home</li> <li>About</li> <li>Contact</li> </ul>

  • Switching from php to python

    - by ts
    Hello I am trying to make a list of things which can be difficult/surprising to someone who is changing language from PHP to Python. so far i have rather short list: forget require / include, learn import (this was most difficult to me - to understand package - module - class - object hierarchy and its mapping to filesystem) you can't just upload file on server to have webpage (-mod_python, wsgi etc) learn the python way for use variable class names (new $class() vs import + getattr) / operator in python 2.x and all float-related horrors those were difficult to me, it takes few days before mind adapts a new paradigm after i found that there is few other areas which could be challenging for someone with (too) many years of php: everything is an object you have to live with exceptions array vs list, set, dictionary, tuple ... learn (effective) list comprehensions learn generators any other ideas / personal experiences ?

  • Can a raw Lucene index be loaded by Solr?

    - by wynz
    Some colleagues of mine have a large Java web app that uses a search system built with Lucene Java. What I'd like to do is have a nice HTTP-based API to access those existing search indexes. I've used Nutch before and really liked how simple the OpenSearch implementation made it to grab results as RSS. I've tried setting Solr's dataDir in solrconfig.xml, hoping it would happily pick up the existing index files, but it seems to just ignore them. My main question is: Can Solr be used to access Lucene indexes created elsewhere? Or might there be a better solution?

  • Pointer aliasing- in C++0x

    - by DeadMG
    I'm thinking about (just as an idea) disjointed pointer aliasing in C++0x. I was thinking about seeing if it could be implemented similarly to const correctness- that is, enforced by the compiler. What would be the requirements for such a thing? As this is more of a thought experiment, I'm perfectly happy to look at solutions that destroy legacy code or redefine half the language and that kind of thing. What I'd really rather not do is have, say, restrict from C99 where the programmer just promises it. It should be enforced.

  • 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,

  • NSString inheritance

    - by Stef
    Hi, I'm doing an useless thing for my first step in Obj-C @interface String : NSString { int m_isnull; } - (id) init; - (int) isNull; @end @implementation String - (id) init { self = [super init]; m_isnull=1; return self; } - (int) isNull { return m_isnull; } @end test : String *a; a=@"ok"; Works fine, but just 2 little questions 1) When I'm compiling I have this warning warning: incompatible Objective-C types assigning 'struct NSString *', expected 'struct String *' I don't know how to avoid it !? 2) a=@"ok" is a fastest way to initialize a string, but when I'm debugging, I don't stop by at my init constructor why ?
