  • PHP Extract Values From One String Based on a Pattern Defined in Another

    - by ironkeith
    I have two strings: $first = '/this/is/a/string'; $second = '/this/:param1/a/:param2'; And I'm trying to get this: $params = array('param1' => 'is', 'param2' => 'string'); But getting from point a to b is proving more than my tired brain can handle at the moment. Anything starting with a ':' in the second string defines a variable name/position. There can be any number of variables in $second which need to be extracted from $first. Segments are separated by a '/'. Thanks.

  • Javascript function programming — receiving elaborate parameters

    - by Barney
    I'm writing a Javascript function that would manipulate an array written on-the-fly and sent as a parameter. The function is written as follows: function returnJourney(animation,clean){ var properties = {}; // loads of other inane stuff for(i in animation[0]) properties[animation[0][i]] = animation[0].i; // heaps more inane stuff } The animation in question is a set of parameters for a jQuery animation. Typically it takes the format of ({key:value,key:value},speedAsInteger,modifierAsString). So to kick off initial debugging I call it with: returnJouney(({'foo':'bar'},3000),1); And straight off the bat things are way off. As far as I see it this would have returnJourney acknowledge clean === 1, and animation being an array with an object as its first child and the number 3000 as its second. Firebug tells me animation evaluates as the number 3000. What am I doing wrong?

  • Execution sequence inside a jquery event handler

    - by user576358
    I have a big issue with the execution squence inside this jquery handler : Was wondering if anyone has come accross this before: I have a simple form: <form action='foo.cgi' id='myForm' > <input type=text name='name' /> <input type=submit value='Find it!'/> </form> when user clicks on Find it! would like to change the cursor to 'progress' before the data is returned through an ajax call: $(document).ready(function(){ $("#myForm ").submit(function(){ $("body").css("cursor", "progress") ; htmlobj=$.ajax({url:server_url,..........); } } However: The cursor [line 2 above ] does not change until data is returned through ajax - Seems like line 3. gets executed before 2. Any help is greatly appreciated

  • Adding an additional click event to every element (JavaScript / jQuery)

    - by Gausie
    I'm developing a touchscreen application that, aside from everything else, records the amount of times the screen is used so that the user can be reminded to clean the screen after a predefined number of clicks. I've got the click functions written nicely, all I need now is make sure the function is called on a click. I imagine $('*').click(function() { //do something }); would accomplish my goal, but is that the best way? Also, would that overwrite other click functions assigned to the elements?

  • .NET Based Radio Automation

    - by Brent Pabst
    I'm curious if anyone has seen an Open Source radio automation package (I found one in Russian on CodePlex) built on .NET In addition if I wanted to build something like this in a client server environment is WCF and WPF the best way to do it? Is it fast enough to trigger songs to play/encode on the server from a remote WPF client? Sort of vague questions but I wanted to get some community feedback.

  • Socket Programming for the Web

    - by Benny
    I have to interact with a legacy system that accepts socket communication and messages. My goal is to make the application cross-platform, but I need the ability to push messages to the client (i.e. - .NET's WCF, Java's Comet) and detect when the user closes out of their browser to destroy the socket. I have built a prototype of .NET wrapper + WCF + Silverlight but it is so disconnected it is difficult to manage the state of the user and seems to be a nightmare to support. All of that considered, what would be my best option?

  • Extract elements from list based on object property type

    - by Dustin Digmann
    Often, I have a list of objects. Each object has properties. I want to extract a subset of the list where a specific property has a predefined value. Example: I have a list of User objects. A User has a homeTown. I want to extract all users from my list with "Springfield" as their homeTown. I normally see this accomplished as follows: List users = getTheUsers(); List returnList = new ArrayList(); for (User user: users) { if ("springfield".equalsIgnoreCase(user.getHomeTown()) returnList.add(user); } I am not particularly satisfied with this solution. Yes, it works, but it seems so slow. There must be a non-linear solution. Suggestions?

  • Can Capistrano set variables based on a role?

    - by conickal
    I am trying to use Capistrano to deploy to two different roles, using Bundler on both, however the Bundler command and flags will be different. Is it possible to set variables that are specific to a role? Either something like: set :bundle_flags, "--deployment --quiet", :role => "web" or: role :web do set :bundler_cmd, "--deployment --quiet" end Neither of those two options work, of course. Is there a way to accomplish this, or something like it?

  • Print the first line of a file C programming

    - by Pedro
    void cabclh(){ FILE *fp; char *val, aux; int i=0; char *result, cabeca[60]; fp=fopen("trabalho.txt","r"); if(fp==NULL){ printf("ERROR\n"); return ; } val=(char*)calloc(aux, sizeof(char)); while(fp='\n'){ fgets(cabeca,60,fp); printf("%s\n",cabeca); } fclose(fp); free(fp); } I want to open a file and print the first line. the problem here is in while(fp='\n'), what i'm doing wrong. How can i make a function that recognize the first char from a file... like: FILE *arq; char info[20]; arq=fopen("trabalho.txt","r"); if(fp==NULL){ printf("ERROR\n"); return ; } if(fp[0]='-'){ //check if the first element is a '-' printf("It's info\n"); }

  • HTML5 Canvas and Game Programming

    - by LemonBeagle
    I hope this isn't too open ended. I'm wondering if there is a better (more battery-friendly) way of doing this -- I have a small HTML 5 game, drawn in a canvas (let's say 500x500). I have some objects whose positions I update every 50ms or so. My current implementation re-draws the entire canvas every 50ms. I can't imagine that being very good for battery life on mobile platforms. Is there a better way to do this? This must be a common pattern with games. EDIT: as requested, here are some more updates: Right now, the objects are geometric primitives drawn via arcs and lines. I'm not opposed to making these small png/jpg/gif files instead of that'd help out. These are small graphics -- just 15x15 or so. As the game progresses, more and more of the screen changes at a time. However, at the start, the screen changes relatively slowly (the objects randomly moved a few pixels every 50ms).

  • Polling a web URL until event

    - by Jaxo
    I'm really sorry about the crappy title - if anybody has a better way of wording it, please edit it! I basically need to have a C# application run a function if the output of a URL is a certain value. For example, if the website says blue the background colour will be blue, red to make it red, etc. The problem is I don't want to spam my webserver with checks. The 4 bytes it downloads each time is negligible, but if I were to deploy this type of system on multiple computers, it would get slower and slower and the bandwidth would add up quickly. So my question is: How can my desktop application run a piece of code only when a web URL has a different output without checking each time? I can't use sockets, and any sort of LAN protocol won't end up working. My reasoning behind this potentially nefarious code is to be able to mute computers by updating a file on the website (as you may have seen in my previous question today, sorry!). I'd like it to be rather quick, and not have the refresh time minutes apart, a few seconds at the most would be ideal. How can I accomplish this? The website's code is easy, but getting the C# application to check when it changes is the part I'm stuck on. Nothing shows up on the website other than the command. Thanks!

  • Win32 reset event like synchronization class with boost C++

    - by fgungor
    I need some mechanism reminiscent of Win32 reset events that I can check via functions having the same semantics with WaitForSingleObject() and WaitForMultipleObjects() (Only need the ..SingleObject() version for the moment) . But I am targeting multiple platforms so all I have is boost::threads (AFAIK) . I came up with the following class and wanted to ask about the potential problems and whether it is up to the task or not. Thanks in advance. class reset_event { bool flag, auto_reset; boost::condition_variable cond_var; boost::mutex mx_flag; public: reset_event(bool _auto_reset = false) : flag(false), auto_reset(_auto_reset) { } void wait() { boost::unique_lock<boost::mutex> LOCK(mx_flag); if (flag) return; cond_var.wait(LOCK); if (auto_reset) flag = false; } bool wait(const boost::posix_time::time_duration& dur) { boost::unique_lock<boost::mutex> LOCK(mx_flag); bool ret = cond_var.timed_wait(LOCK, dur) || flag; if (auto_reset && ret) flag = false; return ret; } void set() { boost::lock_guard<boost::mutex> LOCK(mx_flag); flag = true; cond_var.notify_all(); } void reset() { boost::lock_guard<boost::mutex> LOCK(mx_flag); flag = false; } }; Example usage; reset_event terminate_thread; void fn_thread() { while(!terminate_thread.wait(boost::posix_time::milliseconds(10))) { std::cout << "working..." << std::endl; boost::this_thread::sleep(boost::posix_time::milliseconds(1000)); } std::cout << "thread terminated" << std::endl; } int main() { boost::thread worker(fn_thread); boost::this_thread::sleep(boost::posix_time::seconds(1)); terminate_thread.set(); worker.join(); return 0; } EDIT I have fixed the code according to Michael Burr's suggestions. My "very simple" tests indicate no problems. class reset_event { bool flag, auto_reset; boost::condition_variable cond_var; boost::mutex mx_flag; public: explicit reset_event(bool _auto_reset = false) : flag(false), auto_reset(_auto_reset) { } void wait() { boost::unique_lock<boost::mutex> LOCK(mx_flag); if (flag) { if (auto_reset) flag = false; return; } do { cond_var.wait(LOCK); } while(!flag); if (auto_reset) flag = false; } bool wait(const boost::posix_time::time_duration& dur) { boost::unique_lock<boost::mutex> LOCK(mx_flag); if (flag) { if (auto_reset) flag = false; return true; } bool ret = cond_var.timed_wait(LOCK, dur); if (ret && flag) { if (auto_reset) flag = false; return true; } return false; } void set() { boost::lock_guard<boost::mutex> LOCK(mx_flag); flag = true; cond_var.notify_all(); } void reset() { boost::lock_guard<boost::mutex> LOCK(mx_flag); flag = false; } };
