  • Regex pattern help (I almost have it, just need a bit of expertise to finish it)

    - by Mohammad
    I need to match two cases js/example_directory/example_name.js and js/example_directory/example_name.js?12345 (where 12345 is a digit string of unknown length and the directory can be limitless in depth or not exist at all) I need to capture in both cases everything between js/ and .js and if ? exists capture the digit string after ? This is what I have so far ^js/(.*).js\??(\d+)? This works except it also captures js/example_directory/example_name.js12345 I want the regex to ignore that. Any suggestions? Thank you all! Test your patterns here

  • Porting library from Java to Python

    - by Mike Griffith
    I'm about to port a smallish library from Java to Python and wanted some advice (smallish ~ a few thousand lines of code). I've studied the Java code a little, and noticed some design patterns that are common in both languages. However, there were definitely some Java-only idioms (singletons, etc) present that are generally not-well-received in Python-world. I know at least one tool (j2py) exists that will turn a .java file into a .py file by walking the AST. Some initial experimentation yielded less than favorable results. Should I even be considering using an automated tool to generate some code, or are the languages different enough that any tool would create enough re-work to have justified writing from scratch? If tools aren't the devil, are there any besides j2py that can at least handle same-project import management? I don't expect any tool to match 3rd party libraries from one language to a substitute in another.

  • Can the google map API return a street address that was clicked.

    - by Code
    Hi guys, I'm trying to work out an app design in my head and I would like the user to be able to click there destination address on the map of there area. If I know the user is in Liverpool is it possible to pop up the map over liverpool and then allow the user to select on the map where they wanna go, and the google map/api return the street or the name of the area? I've never used googlemap/api yet so just wondering if this kind of thing is possible on the iphone yet. Many Thanks -Code

  • Sending SMS using Java ME application

    - by iamrohitbanga
    I want to a Java ME application that transfers any SMS received to a PC using bluetooth. The PC can then direct the Java ME application via bluetooth to send a response SMS. Is there library available for this architecture or I have to design it myself? Is this approach correct or a better one exists? I want to use bluetooth as then I will not have dependency on the cable.

  • Use multiple inheritance to discriminate useage roles?

    - by Arne
    Hi fellows, it's my flight simulation application again. I am leaving the mere prototyping phase now and start fleshing out the software design now. At least I try.. Each of the aircraft in the simulation have got a flight plan associated to them, the exact nature of which is of no interest for this question. Sufficient to say that the operator way edit the flight plan while the simulation is running. The aircraft model most of the time only needs to read-acess the flight plan object which at first thought calls for simply passing a const reference. But ocassionally the aircraft will need to call AdvanceActiveWayPoint() to indicate a way point has been reached. This will affect the Iterator returned by function ActiveWayPoint(). This implies that the aircraft model indeed needs a non-const reference which in turn would also expose functions like AppendWayPoint() to the aircraft model. I would like to avoid this because I would like to enforce the useage rule described above at compile time. Note that class WayPointIter is equivalent to a STL const iterator, that is the way point can not be mutated by the iterator. class FlightPlan { public: void AppendWayPoint(const WayPointIter& at, WayPoint new_wp); void ReplaceWayPoint(const WayPointIter& ar, WayPoint new_wp); void RemoveWayPoint(WayPointIter at); (...) WayPointIter First() const; WayPointIter Last() const; WayPointIter Active() const; void AdvanceActiveWayPoint() const; (...) }; My idea to overcome the issue is this: define an abstract interface class for each usage role and inherit FlightPlan from both. Each user then only gets passed a reference of the appropriate useage role. class IFlightPlanActiveWayPoint { public: WayPointIter Active() const =0; void AdvanceActiveWayPoint() const =0; }; class IFlightPlanEditable { public: void AppendWayPoint(const WayPointIter& at, WayPoint new_wp); void ReplaceWayPoint(const WayPointIter& ar, WayPoint new_wp); void RemoveWayPoint(WayPointIter at); (...) }; Thus the declaration of FlightPlan would only need to be changed to: class FlightPlan : public IFlightPlanActiveWayPoint, IFlightPlanEditable { (...) }; What do you think? Are there any cavecats I might be missing? Is this design clear or should I come up with somethink different for the sake of clarity? Alternatively I could also define a special ActiveWayPoint class which would contain the function AdvanceActiveWayPoint() but feel that this might be unnecessary. Thanks in advance!

  • What is a common name for inheritance, composition, aggregation, delegation?

    - by Eye of Hell
    Hello. After program is separated into small object, these objects must be connected with each over. Where are different types of connection. Inheritance, composition, aggregation, delegation. These types has many kinds and patterns like loose coupling, tight coupling, inversion of control, delegation via interfaces etc. What is a correct common name for mentioned types of connections? I can suggest that they all are called 'coupling', but i can't find any good classification in google, so maybe i'm trying to use a wrong term? Maybe anyone knows a solid, trusted classification that i can user for terminology?

  • Searching for a complex and well-designed PHP OOP application to learn from

    - by Raveren
    Basically, I am diving ever deeper into complex programming practices. I've almost no friends that are experienced (or more experienced than me) programmers to learn from, so I am looking for the next best thing - learning from the work of strangers. Can anyone recommend a real world finished and working application written well and OOP-centered. I'd like to take and analyze its source. Bonus if it's based on Zend Framework. What I am interested most in is objects that unlike desktop applications, have only one real operation done to them (or to their representation in DB or session) during their lifetime (or pageload), like user-logIn(). I'm interested in optimal and reusable design patterns and their real life implementations.

  • Disable JPanel with visual effect

    - by Ryan
    I'm looking for a good way to disable a JPanel. I'm using a MVC design for a Java Swing GUI. I want the JPanel to be disabled while the model is processing stuff. I've tried setEnabled(false). That disables user input on the JPanel, but I'd like it to be grayed out to add a more visual effect. Thanks in advance!

  • GAE transaction exception suggestion

    - by bach
    Hi, The current situation encourages the design of the system to split object fields to seperate objects in order to reduce the chance of the JDOCanRetryException to be thrown. If we could have the fields that were changed by the other client who changed the object in the exception content itself we could deside whether to re-retrieve the object or ignore...

  • Providing unique layout for specific resolution in Android 2.3.3

    - by user1384991
    I need to use specific xml-layouts based on screen resolution, not size. So, the first design is used for resolution <= 480x800, and the second - for resolution = 480x800. How is it done ? update. Possible solution: Display display = ((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay(); final int height = display.getHeight(); final int width = display.getWidth();

    I have created a simple view consisting of 3 tables in SQL. By right clicking and selecting Design, in the Object explorer table, i modified my custom view. I just added sortby asc in a field. The problem is that the changes are not reflected in the outout of the View. After saving the view, and selecting Open view the sort is not displayed in output. So what is going on here?

  • prevent IE Mobile from scaling web pages automatically

    - by Adam
    I have not been able to get IE mobile to stop automatically resizing my site design. I am using three stylesheets with media queries to display the site differently on different device screens. I've included the meta tag so it shows the mobile stylesheet on IE mobile but it keeps setting the viewport at 320X480 instead of using the actual size of 480X800. How can I force it to display at the actual screen size instead of scaling for a smaller resolution?

  • Is there an open source repository for SQL code?

    - by morpheous
    I find myself writing SQL code (queries or stored procs) to solve problems that can definitely be defined as 'patterns' that occur frequently in business. Rather than having to wrack my brain each time I encounter a new problem (which must have been solved a countless times by other coders/db analysts, I wondered if there was a repository I could go to check out (peer reviewed) code - and maybe add my two pence every now and then. I know different db vendors tend to write slightly variant forms of SQL - but there could still be a repository with ANSI stuff and proprietary stuff. Hopefully, such a site would encourage more people to write standardized SQL. Is there such a site?. If no - why not? (would anyone else be interested in such a site?) If such a site exists, please provide link(s), as Google is not finding anything remotely useful.
