  • Wrap output of struts2 ServletDispatcherResult ?

    - by krosenvold
    I'd like to do much the same thing as the Struts2 sitemesh servlet-filter does, i.e. wrap the output of an action with some chosen content. The "problem" with the sitemesh approach is that it AFIK it does not have any relationship to the ActionInvocation, and I would like to be able to query information from the ActionInvocation when determining which content to add. I have looked through the ServletDispatcherResult, and I'm not entirly sure what's the best way to achieve this. Any suggestions ?

  • Auto-Completion in Unix VI editor

    - by IllustratedInsomnia
    Hey guys, after using graphical IDE's like Visual Studio, I'm used to pressing CTRL+Space to auto-complete a variable or function name. Now, I know such a thing isn't completely possible in VI, but I heard there was a list of commands that could be mapped that allowed automatic completion of variables and functions in the current file opened. Does anyone know what this sequence is? Thanks in advance.

  • Using time facets on universal_time

    - by scooterman
    Hi all, on boost, to create a time facet to format an specified time we use the folowing: boost::local_time::local_time_facet* facet = new boost::local_time::local_time_facet("%Y%m%d %H:%M:%S.%f"); std::stringstream date_stream; date_stream.imbue(std::locale(date_stream.getloc(), facet)); date_stream << boost::local_time::local_microsec_clock::local_time(boost::local_time::time_zone_ptr()); How do I do the same thing, but using an universal clock: boost::posix_time::microsec_clock::universal_time() Thanks

  • An idea for something similar to delicious bookmarking

    - by Andrew Welch
    Hi, This is an idea more than a question, but I thought it would be the right community. I really like mindmapping as a way to organise information and I think it would be really cool to have a piece of software that allowed you to organise bookmarks into a dynamic mind map. If I get time I would start to create such a thing. Any thoughts or does it already exist? Thanks Andy

  • Camera and Image recognition

    - by kjh
    I recently watched a youtube video where a guy got a camera to recognize when a rubik's cube was held up to it, and it captured the 9 square color combination before snapping a picture of the cube and displaying the 3x3 grid on the screen of his computer. What kind of programming is this and where would I start reading to get into this sort of thing? specifically, controlling a camera, and getting it to pick out certain parts of an image and translate that data.

  • iPhone - Tweak the UINavigationController to show a UINavigationBar made into IB

    - by Oliver
    Hello, I've build a UINavigationBar into Interface Builder, and I have a NavigationController into my app. I'd like to make the one use the other to work. Just to manage the bar into IB and let the controller use it as its view (and adding by itself the Back button if needed), or in another way to do the same thing, let the NavBar use the navcontroller to adjust its display. Do you see a way to do this ? If not, I really don't see the use of the NavigationBar proposed into IB.

  • Updating a single file in a compressed tar

    - by Phil
    Given a compressed archive file such as application.tar.gz which has a folder application/x/y/z.jar among others, I'd like to be able to take my most recent version of z.jar and update/refresh the archive with it. Is there a way to do this other than something like the following? tar -xzf application.tar.gz cp ~/myupdatedfolder/z.jar application/x/y tar -czf application application.tar.gz I understand the -u switch in tar may be of use to avoid having to untar the whole thing, but I'm unsure how to use it exactly.

  • Why is changing displays slow?

    - by Josh Bronson
    I've had many laptops over the course of many years, and while many things have sped up, one thing remains as slow today as it was years ago: (dis)connecting an external display. What's taking it so long to detect the new display and update the pixel buffers? I use Macs primarily, but I think this is equally slow on other platforms.

  • Green Bars in Visual Studio 2010

    - by Braveyard
    I am wondering what these greens things are in Visual Studio 2010. What are they for? They look pretty random but of course they have to have some meaning. Can any one tell me? At first glance they don't mean any thing to me. Picture 1: Picture 2: Edit: They show saved changed content during the document open. Once you close the document they disappear.

  • What's the difference between the ruby irb prompt modes?

    - by Steven
    I can change the irb prompt mode with irb --prompt prompt-mode I can see what null and simple does, but I can't tell the difference between null and xmp and the difference between default/classic/inf-ruby. Can someone explain to me what these other modes do? It seems pointless to have multiple modes doing the same thing.

  • Regular - Take all numeric characters following a text character

    - by Simon
    Given a string in the format: XXX999999v99 (where X is any alpha character and v is any numeric character and v is a literal v character) how can I get a regex to match the numeric chatacters following the v? So far I've got 'v\d\d' which includes the v but ideally I'd like just the numeric part. As an aside does anyone know of a tool in which you can specify a string to match and have the regex generated? Modifying an existing regex is one thing but I find starting from scratch painful!

  • Sum up values in an array list in java

    - by user1449997
    Hello to all tired and frustrated programmers, There is a problem I can't solve: In my array list there are Object arrays with the length of three and always on the last cell of the array there is a double. I need a loop which goes through the array list and sums up all doubles. (I need also some other thing from the arrays so a general idea how to loop through an array list would be perfect :-)) Any ideas? Thanks for your help, Greetings Demian

  • Why ruby has to_s and inspect?

    - by prosseek
    The p calls inspect, and puts/print calls to_s for representing its object. If I run class Graph def initialize @nodeArray = Array.new @wireArray = Array.new end def to_s # called with print / puts "Graph : #{@nodeArray.size}" end def inspect # called with p "G" end end if __FILE__ == $0 gr = Graph.new p gr print gr puts gr end I get G Graph : 0Graph : 0 Then, why does ruby has two functions do the same thing? What makes the difference between to_s and inspect? If I comment out the to_s or inspect function, I get as follows. ##

  • Can I migrate from ClearCase to Serena VM?

    - by Rich B
    I have a repository using Rational ClearCase Explorer 2003.06.10+ which I want to migrate into Serena ChangeMan Version Manager 8.1.4.2. Is this possible? The ClearCase repository was not used for all it's functions, just as a place to hold copies of documents, so the only thing I need to keep is the files and their version histories.

  • YUI dialog - what's the equivalent of postdata when using "form" (not ('async")

    - by jamesmoorecode
    I'm creating a dialog with YAHOO.widget.Dialog. The dialog is fired off by clicking on a link, and the function the link uses specifies parameters that finally get added to a postdata option like so: var myDialog = new YAHOO.widget.Dialog("myDialog", { fixedcenter: true, // postmethod: "form", postdata: propString }); This works just fine, but now I need to do the same thing but using "form" instead of "async" - and there's no postdata for form submissions. What's the right way to do this? (YUI 2.7.0)

  • Can I get a person's display name or composite name from Apple AddressBook on OSX platform?

    - by AlexT
    I have come across ABRecordCopyCompositeName() in these pages but, having Spotlighted it, have a hunch it's only available for the IOS platform. The AddressBook app itself, and ABPeoplePicker obviously do something similar internally, so is there an equivalent API for OSX? It's a tedious thing to retrieve title, first name, middle name, last name, suffix and work out if it's a company before building it yourself.
