Is there any (easy) way to do this? Thanks!

  • Creating a java library

    - by Albinoswordfish
    This may be a silly question, but right now I have a rather large class that I want to use as a library. Where somebody can simply add this jar file to their classpath. And then simply do an import statement at the top, then he or she can start using this class. Is there anything special I need to do or can I simply just use the jar file built?

  • Cloud computing?

    - by Shawn H
    I'm an analyst and intermediate programmer working for a consulting company. Sometimes we are doing some intensive computing in Excel which can be frustrating because we have slow computers. My company does not have enough money to buy everyone new computers right now. Is there a cloud computing service that allows me to login to a high performance virtual computer from remote desktop? We are not that technical so preferrably the computer is running Windows and I can run Excel and other applications from this computer. Thanks

  • What's the best way to trim std::string

    - by Milan Babuškov
    I'm currently using the following code to right-trim all the std::strings in my programs: std::string s; s.erase(s.find_last_not_of(" \n\r\t")+1); It works fine, but I wonder if there are some end-cases where it might fail? Of course, answers with elegant alternatives and also left-trim solution are welcome.

  • Standard way to hash an RSA key?

    - by Adam J.R. Erickson
    What's the algorithm for creating hash (sha-1 or MD5) of an RSA public key? Is there a standard way to do this? Hash just the modulus, string addition of both and then take a hash? Is SHA-1 or MD5 usually used? I want to use it to ensure that I got the right key (have the sender send a hash, and I calculate it myself), and log said hash so I always know which exact key I used when I encrypt the payload.

    - by Mark
    I have noticed that on the iPad the google maps app has a very cool page curl control that sits in the bottom right hand corner that allows the user to change configuration settings. Is this control accessible for everyday developers, or was in built specifically for google maps on the iPad? Thanks

  • WPF ListBox's scrollviewer customizable so that there is no Scrollbar, only RepeatButtons

    - by John
    Hi I would like to customize the scrollbars of a listbox's scrollviewer in such a way that the scrollbar only consists of a RepeatButton for scrolling up and a Repeatbutton for scrolling down. Nothing else. There should be no scrollbar (track) between the buttons. One button should be to the left of the ItemsPanel (scroll up) and the other on the right of the ItemsPanel. Is that possible?

  • Do WordPress widget (or sidebar) hooks exist?

    - by Jeff
    I'm trying to filter ALL widget output through a simple filter, but can't find any hooks and was hoping to be pointed in the right direction. Or possibly my efforts are not even possible? My simple filter is something like this: function clean_widget_output( $input ) { return str_replace( array( "\t", "\n", "\r" ), '', $input ); } add_[FILTER OR ACTION]( 'need_a_hook', 'clean_widget_output', 99 ); Any ideas? I'm pretty new to PHP, but I can get around.

  • Regex to exclude 1 word out of a regex code.

    - by Mech Software
    I need a regex expert to help out on this one. Examples I've found on here and the net I cant seem to get right. I'm using PHP and I have the following regex expression /([^a-zA-Z0-9])GC([A-Z0-9]+)/ This matches items like GCABCD GC123A, etc. What i need to do is EXCLUDE GCSTATS from this. So basically I want it to work just as it has, except, ignore GCSTATS in the regex.

  • XCode missing inline test results

    - by Vegar
    Everywhere there are pretty pictures of failing tests shown inline in the code editor, like in Peepcodes Objective-C for Rubyist screencast and in apples own technical documentation: When I build my test-target, all I get is a little red icon down in the right corner, stating something went wrong. When clicking on it, I get the Build Results, where I can start to hunt for test results. Do anyone have a clue on what´s wrong?

  • Combined states, FSM

    - by bobobobo
    Not sure this is the right place to ask, but is it "correct" to combine states of an FSM? Say you have an object with enum State { State1 = 1 << 0, State2 = 1 << 1, State3 = 1 << 2 } ; It just so happens that it makes sense to combine states, as in State myState = State1 | State2 ; however in FSM theory is this illegal?

  • Using jQuery to Dynamically Insert Into List Alphabetically

    - by Dex
    I have two ordered lists next to each other. When I take a node out of one list I want to insert it alphabetically into the other list. The catch is that I want to take just the one element out and place it back in the other list without refreshing the entire list. The strange thing is that when I insert into the list on the right, it works fine, but when I insert back into the list on the left, the order never comes out right. I have also tried reading everything into an array and sorting it there just in case the children() method isn't returning things in the order they are displayed, but I still get the same results. Here is my jQuery: function moveNode(node, to_list, order_by){ rightful_index = 1; $(to_list) .children() .each(function(){ var ordering_field = (order_by == "A") ? "ingredient_display" : "local_counter"; var compA = $(node).attr(ordering_field).toUpperCase(); var compB = $(this).attr(ordering_field).toUpperCase(); var C = ((compA > compB) ? 1 : 0); if( C == 1 ){ rightful_index++; } }); if(rightful_index > $(to_list).children().length){ $(node).fadeOut("fast", function(){ $(to_list).append($(node)); $(node).fadeIn("fast"); }); }else{ $(node).fadeOut("fast", function(){ $(to_list + " li:nth-child(" + rightful_index + ")").before($(node)); $(node).fadeIn("fast"); }); } } Here is what my html looks like: <ol> <li ingredient_display="Enriched Pasta" ingredient_id="101635" local_counter="1"> <span class="rank">1</span> <span class="rounded-corners"> <span class="plus_sign">&nbsp;&nbsp;+&nbsp;&nbsp;</span> <div class="ingredient">Enriched Pasta</div> <span class="minus_sign">&nbsp;&nbsp;-&nbsp;&nbsp;</span> </span> </li> </ol>
