  • Regular Expression Question

    - by zyq524
    I'm trying to use regular expression to extract the comments in the heading of a file. For example, the source code may look like: //This is an example file. //Please help me. #include "test.h" int main() //main function { ... } What I want to extract from the code are the first two lines, i.e. //This is an example file. //Please help me. Any idea?

  • Using google maps API, how can we set the current location as the default set location using map.set

    - by vs1984
    I am writing Javascript code using Google maps API. map = new google.maps.Map2(document.getElementById("map_canvas")); map.setCenter(new google.maps.LatLng(37.4419, -122.1419), 13); The above code sets the default location of the map canvas to Palo Alto. How can we write the script in such a way that the setCenter function automatically points to the current location of the client?

  • How to implement a tagging plugin for jQuery

    - by anxiety
    Goal: To implement a jQuery plugin for my rails app (or write one myself, if necessary) that creates a "box" around text after a delimiter is typed. Example: With tagging on SO, the user begins typing a tag, then selects one from the drop-down list provided. The input field recognizes that a tag has been selected, puts a space and then is ready for the next tag. Similarly, I am attempting to use this plugin to put a box around the previously entered tag before moving to to accept the next tag/input. The instructions in the README.txt seem simple enough, however I have been receiving a $(".tagbox").tagbox is not a function error when debugging my app with firebug. Here is what I have in my application.js: $(document).ready( function(){ $('.tagbox').tagbox({ separator: /\[,]/, // specifying comma separation for <code>tags</code> }); }); And here is my _form.html.erb: <% form_for @tag do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= text_field :tag, :name, { :method => :get, :class => "tagbox" } %> </p> <p><%= f.submit "Submit" %></p> <% end %> I have omitted some other code (namely the implementation of an autocomplete plugin) existing within my _form.html.erb and application.js for sake of readability. The inclusion or exclusion of this omitted code does not affect the performance of this plugin. I have included all of the necessary files for the tagbox plugin (as well as application.js after all other included JS files) within the javascript_include_tag in my application.html.erb file. I'm pretty much confused as to why I'd be getting this "not a function" error when jquery.tagbox.js clearly defines the function and is included in the head of my html page in question. I've been struggling with this plugin for longer than I'd like to admit, so any help would really be appreciated. And, of course, I'm open to any other plugins or from-scratch suggestions you may have in mind.. This tagbox plugin does not seem to have a wealth of documentation or any currently working examples. Also to note, I'm trying to avoid using jrails. Thanks for your time

  • Isthere an equivalent in CDI(WELD) to Guice modules and Inject ?

    - by mP
    I like the way Guice makes it fairly straight forward to manually create your own modules each with their own bindings done in code. CDI on the other hand seems to rely more on magic rather than programmatic access to sest bindings. Am i wrong or how can one achieve the same effect with WELD. Any code sample would be appreciated...

  • Email SMTP validator

    - by Hrvoje
    I need to send hundreds of newsletters, but would like to check first if email exists on server. It's called smtp validation, at least i think so, based on my research on net. There's several libraries that can do that, and also a page with open-source code in asp (http://www.coveryourasp.com/ValidateEmail.asp#Result3), but I have hard time reading classic asp, and it seams that it uses some third-party library... Does someone have code for smtp validation in c#, and/or general explanation of how it works?

  • How do I REALLY get started programming in Ruby on Rails

    - by Nate
    I can't figure out where exactly to go in order to write the Ruby code itself. I know that I can enter things line-by-line in Terminal (I'm on a Mac), but I'd like to figure out how to start using something like Xdrive (Apple won't allow me to download Xrive because I have OS X 10.5, not 10.6). What steps do I need to take in order to start writing code in a program like xDrive. Thank you in advance.

  • What is the best VCS Solution for Windows?

    - by Alix Axel
    My code base is getting quite big and it's difficult to organize all the different branches using just directories, I was wondering what would be a decent version control system for my own personal use that works (with little hassle) on Windows? PS: I'm not looking for hosted VCS like GitHub, SourceForge or Google Code.

  • Should mutex.WaitOne() inside or before the try/finally block.

    - by chillitom
    Hi Guys, I was wondering which of the following was the suggested pattern when using Mutex (or Semaphores or ReadWriteLockSlims etc.). Should the initial lock happen inside or outside of the try statement? Is it unimportant? _mutex.WaitOne() try { // critical code } finally { _mutex.ReleaseMutex(); } or try { _mutex.WaitOne() // critical code } finally { _mutex.ReleaseMutex(); }

  • sigsetjmp and siglongjmp inside signal handler

    - by EpsilonVector
    How do I: sigsetjmp inside the handler and then return from the handler such that the signal will be unmasked once I siglongjmp back to this point? In pseudo code this is sort of the function that I have: signal_handler(){ if(sigsetjmp(env[i++])) return; else siglongjmp(env[i]); } It's supposed to be the context switch code for user threads in Linux.

  • My mental block - struggling to learn Objective C

    - by iqessar
    Hello people, this would be my first question after signing up! Anyway heres my question, I did Java at university and I was always told I am a good programmer. However I never pursued it as a career - I went into support and management instead. Im pretty much bored with my job, I have therefore started to learn Objective C so that I can develop apps for the iphone. I am currently watching several different Videos / Books. My problem is that when I go through the Apple documentation, although I understand most of it, sometimes I stumble. I believe that because you/we have the Apple documentation (i.e. Framework references) , everything should be clear, and therefore you should have no need to refer to a book or video (in order to learn how to use a particular class). But I alway do refer to a book and video and subsequently feel guilty as I believe the framework reference should be enough. (I therefore feel I am not up to being a programmer) I also believe that you shouldn't need example code in order to learn how to use a particular class because Apple provides documentation for each class, but AGAIN I find my self googling example code and I find my answer like that - again I feel guilty for doing this. Am I right in saying that Apple documentation is simply not clear? and that its ok to refer to a video/book or google? or forums for that matter? I have proffesional programmers who tell me that I am worrying too much and that I should get on with it and use all the resources that I have. I just cant seem to get round this mental block that I have in my head. When I start a programming project I am able to use the excellent search skills that I have to find the code I need, copy and paste it (yes I do understand it) BUT then I feel guilty telling myself that why didn't you think up the code yourself???? Therefore your not a real programmer, your just good at googling. Currently I am going through 20+ books so that I can learn most of the frameworks, syntax etc to develop iphone apps. I believe if I do this, then when I think of a project I can make it quickly. Should I read a few books, like 2-3 and then just start a project /app , and if I get stuck just google it and get the code I need? Can anybody please answer my questions?

  • Multiheaded X.org with a single workspace-pool

    - by blauwblaatje
    I've got an idea for x.org/$randomwindowmanager in combination with a multiheaded setup, but I haven't figured out how it should work. Also I don't really know where to place the feature request. Now for the idea. I've been working with screen (wikipedia:GNU_Screen) for some years now. One thing I like about it, is the fact that I can get a multi-display mode (screen -x), so you can have multiple terminals all connected to the same screen. The fun thing about it, is that you can get 2 terminals with the same content and switch my onscreen layout, without moving the terminals. I admit, in screen it's not extremely useful, but I think for a wm it can be. Imagine this. You've got two monitors and 4 workdesks. On one workdesk I've got my IDE with code, on the second one I've got the output, on the third one I've got the documentation and on the forth one I've got my e-mail and IM clients. At one moment, I want my IDE and output on my monitors, another moment my code and documentation and Yet another moment my IM to consult a colleague and documentation or code. Finally my colleague comes to help me at my desk. I'd like it if we could both watch the same workdesk without him sitting on my lap, so I turn one monitor so he can see it better. It would be great if we could see the same thing that's on my monitor (exclude mousepointer). The thing with most WMs is that your workspaces on the two monitors are either separated or glued together. If they're separated, you can change workspaces on each monitor autonomous, but you can't exchange applications between monitors because they're different x-clients (iirc). If they're glued together (xinerama), you can exchange the applications, but when changing your workspace, the other monitors change too. So, what I'd like to know is this. Is this already possible or should I submit a feature request somewhere (and if so, where?)

    hi, I came accross something very strange when i was testing my pages in FireFox. The Adsense blocks are commented out (green) in firefox. It does render however properly when i paste all the rendered code in a blank aspx page in the same project without using masterpage. http://picpaste.com/problem.jpg Here's a picture of the problem. As you can see on one of the pages the script code is green. How is that possible?

  • How to get a physics engine like Nape working?

    - by Glacius
    Introduction: I think Nape is a relatively new engine so some of you may not know it. It's supposedly faster than box2d and I like that there is decent documentation. Here's the site: http://code.google.com/p/nape/ I'm relatively new to programming. I am decent at AS3's basic functionality, but every time I try to implement some kind of engine or framework I can't even seem to get it to work. With Nape I feel I got a little further than before but I still got stuck. My problem: I'm using Adobe CS5, I managed to import the SWC file like described here. Next I tried to copy the source of one of the demo's like this one and get it to work but I keep getting errors. I made a new class file, copied the demo source to it, and tried to add it to the stage. My stage code basically looks like this: import flash.Boot; // these 2 lines are as described in the tutorial new Boot(); var demo = new Main(); // these 2 are me guessing what I'm supposed to do addChild(demo); Well, it seems the source code is not even being recognized by flash as a valid class file. I tried editing it, but even if I get it recognized (give a package name and add curly brackets) but I still get a bunch of errors. Is it psuedo code or something? What is going on? My goal: I can imagine I'm going about this the wrong way. So let me explain what I'm trying to achieve. I basically want to learn how to use the engine by starting from a simple basic example that I can edit and mess around with. If I can't even get a working example then I'm unable to learn anything. Preferably I don't want to start using something like FlashDevelop (as I'd have to learn how to use the program) but if it can't be helped then I can give it a try. Thank you.
