  • rhino embedding

    - by neheh
    Anyone understands the rhino javascript Contexts? I cannot find any useful documentation about it. My main problem is the Context.exit() (really should be cx.exit()) which from what I understand exits the context associated with the current thread? Does that mean I need to keep track of what which thread does? main thread: Context cx; cx.evaluateReader( ... ) // load some function start thread 2 thread 2: Object o= scope.get("methodname", scope); ((Function)o).call( ... ) I do not plan on doing multithreading but what if the different setups comes from different threads?

  • How to strip a GET property from the URL using PHP

    - by James
    I have the following function that get's the current page URL: <?php // get current page url function currentPageUrl() { $pageURL = 'http'; if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";} $pageURL .= "://"; if ($_SERVER["SERVER_PORT"] != "80") { $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; } else { $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; } echo $pageURL; } ?> Which prints: http://localhost/gallery.php?id=23&type=main I want to remove "&type=main" which is present in the url. So before echoing $pageURL I add the following line: $pageUrl = preg_replace("&type=main", "", $pageURL); But it still returns the full url including type=main. How can I get rid of that from the url?

  • A Simulator for a non-deterministic Push-Down Automaton

    - by shake
    Well, i need to make simulator for non-deterministic Push-Down Automaton. Everything is okey, i know i need to do recursion or something similar. But i do not know how to make that function which would simulate automaton. I got everything else under control, automaton generator, stack ... I am doing it in java, so this is maybe only issue that man can bump on, and i did it. So if anyone have done something similar, i could use advices. This is my current organisation of code: C lasses: class transit: list -contains non deterministic transitions state input sign stack sign class generator it generate automaton from file clas NPA public boolean start() - this function i am having trouble with Of course problem of separate stacks, and input for every branch. I tried to solve it with collection of objects NPA and try to start every object, but it doesn work :((..

  • adding a flash object to FancyBox using jquery swfobject

    - by Freeman
    Fellows, I dont seem to be getting a solution. I have a a video gallery which I create by dynamically from a database. I have managed to create a flash object which plays well without FancyBox, however I want a person to click on the gallery and then an swobject is created which will then be show on a fancybox. Here is part of my javascript which is not working. $.ajax({ data:"search=vids&id="+ art, type: "POST", url: "doyit.php", success: function(msg){ $(".videogallery").html('<h3>Click to view videos of '+name+'</h3>'+msg); $('.video').bind('click',function(ev){ var vid=$(this).attr("href"); var img=$(this).find("img").attr("src") $(this).flash({swf: "mediaplayer.swf", flashvars: { file: vid, image: img } }) $(this).fancybox( { ajax:{ type:"POST"}, 'padding' : 0, 'autoScale' : false, 'transitionIn' : 'none', 'transitionOut' : 'none', 'title' : this.title, 'width' : 680, 'height' : 495 } ); $(this).unbind(ev) return false; }) } Any suggestions?

  • What is the safest way to pass strings around in C?

    - by chucknelson
    I have a program in C using Solaris with VERY ancient compatibility it seems. Many examples, even here on SO, don't work, as well as lots of code I've written on Mac OS X. So when using very strict C, what is the safest way to pass strings? I'm currently using char pointers all over the place, due to what I thought was simplicity. So I have functions that return char*, I'm passing char* to them, etc. I'm already seeing strange behavior, like a char* I passed having its value right when I enter a function, and then the value being mysteriously gone OR corrupted/overwritten after something simple like one printf() or an malloc to some other pointer. I was thinking maybe declaring a local char[] inside each function, using strcpy() immediately, and then eventually returning a pointer where char *returnval = strdup(localchar[]); This seems...sloppy. Can anyone point me in the right direction on a simple requirement?

  • Cake PHP redirect with parameters in url

    - by megaboss98
    I have a page that I want to redirect to that requires parameters in the URL: http://www.mysite.com/myController/myAction/param1:val1/param2:val2 I know that there is a Cake PHP redirect function for redirecting that works as follows: $this->redirect(array("controller" => "myController", "action" => "myAction", $data_can_be_passed_here), $status, $exit); How do I add the parameters that I want as part of the url using the above function? I would think that there might be another element that I could add to array so that I can pass along "param1:val1" and "param2:val2". Any help would be greatly appreciated!

  • Intellisense in Visual Studio 2010

    - by Erik
    For some reason the Intellisense in vb.net stopped working when I use an Aggregate Lambda expression inside a With statement. With Me.SalesPackage .WebLinks = Sales.Where(Function(f) f.Current.BookerWeb > 0).Count .WebAmount = Aggregate o In Sales.Where(Function(f) f.Current.WebBooker > 0) Into Sum(o.Current.WebPrice) End With If I insert a new line between .WebLinks and .WebAmount and start typing, it works. But it won't work if I do it after the Aggregate statement... Any ideas?

  • Using Fortran to call C++ Functions

    - by Dane Larsen
    I'm trying to get some FORTRAN code to call a couple c++ functions that I wrote (c_tabs_ being one of them). Linking and everything works just fine, as long as I'm calling functions that don't belong to a class. My problem is that the functions I want the FORTRAN code to call belong to a class. I looked at the symbol table using nm and the function name is something ugly like this: 00000000 T _ZN9Interface7c_tabs_Ev FORTRAN won't allow me to call a function by that name, because of the underscore at the beginning, so I'm at a loss. The symbol for c_tabs when it's not in a class is quite simple, and FORTRAN has no problems with it: 00000030 T c_tabs_ Any suggestions? Thanks in advance.

  • Is there any way to "peek" at a file while it's uploading through HTTP onto a Windows box?

    - by iisystems
    I need to add a file upload function to an ASP.NET website and would like to be able to read a small portion of the file on the server while it's still uploading. A peek or preview type function so I can determine contents and give some feedback to the user while it is still uploading (we're talking about large files here). Is there any way to do this? I'm thinking worst case of writing a custom control which uploads only a fixed number of bytes of the file once chosen and then under the covers starts another upload of the full file. Not totally sure even this is possible, but I'm looking for a more elegant solution anyway... Thanks!

  • F# Extention Methods on Lists, IEnumberable, etc

    - by flevine100
    I have searched StackOverflow (and other sources) for this answer, but can't seem to find anything. In C#, if I had a widget definition, say: class widget { public string PrettyName() { ... do stuff here } } and I wanted to allow for easy printing of a list of Widgets, I might do this: namespace ExtensionMethods { public static PrintAll( this IEnumerable<Widget> widgets, TextWriter writer ) { foreach(var w in widgets) { writer.WriteLine( w.PrettyName() ) } } } How would I accomplish something similar with a record type and a collection (List or Seq preferrably in F#). I'd love to have a list of Widgest and be able to call a function right on the collection that did something like this. Assume (since it's F#) that the function would not be changing the state of the collection that it's attached to, but returning some new value.

  • I have a bunch of images being shown on click via JQuery - any easy way to animate this?

    - by Cenk
    This is the (quite simple) JS code I'm using: $(document).ready(function() { $(".button-list .next").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); nextimg = currentimg.next(); firstimg = project.find(".images-list li:first"); currentimg.removeClass("current"); if (nextimg.is("li")) nextimg.addClass("current"); else firstimg.addClass("current"); return false; }); $(".button-list .prev").click(function() { project = $(this).parents().filter(".projektweb").eq(0); currentimg = project.find(".images-list li.current"); previmg = currentimg.prev(); lastimg = project.find(".images-list li:last"); currentimg.removeClass("current"); if (previmg.is("li")) previmg.addClass("current"); else lastimg.addClass("current"); return false; }); }); And this is how the HTML code for the image list looks like: <ul class="images-list"> <li class="current"><img src="img/1.jpg" alt="" /></li> <li><img src="img/1b.jpg" alt="" /></li> </ul> <ul class="button-list"> <li><a class="button prev" href="#">?</a></li> <li><a class="button next" href="#">?</a></li></ul> The CSS: .images-list { height: 460px; list-style-type:none; float:left; width: 460px; overflow:hidden; position:relative; } .images-list img { height: 460px; width: 460px; display:block; } .images-list li { display:none; } .images-list li.current { display:block; } What I'd like to do is animate the images as they come and go - right now they just appear, which is OK but a bit more eye-candy would be nice. Can anyone help me out here? It it even possible to do it this way? Thanks!!

  • PHP Flatten Array with multiple leaf nodes

    - by tafaju
    What is the best way to flatten an array with multiple leaf nodes so that each full path to leaf is a distinct return? array("Object"=>array("Properties"=>array(1, 2))); to yield Object.Properties.1 Object.Properties.2 I'm able to flatten to Object.Properties.1 but 2 does not get processed with recursive function: function flattenArray($prefix, $array) { $result = array(); foreach ($array as $key => $value) { if (is_array($value)) $result = array_merge($result, flattenArray($prefix . $key . '.', $value)); else $result[$prefix . $key] = $value; } return $result; } I presume top down will not work when anticipating multiple leaf nodes, so either need some type of bottom up processing or a way to copy array for each leaf and process (althought that seems completely inefficient)

  • javascript filter nested object based on key value

    - by murray3
    I wish to filter a nested javascript object by the value of the "step" key: var data = { "name": "Root", "step": 1, "id": "0.0", "children": [ { "name": "first level child 1", "id": "0.1", "step":2, "children": [ { "name": "second level child 1", "id": "0.1.1", "step": 3, "children": [ { "name": "third level child 1", "id": "0.1.1.1", "step": 4, "children": []}, { "name": "third level child 2", "id": "0.1.1.2", "step": 5, "children": []} ]}, ]} ] }; var subdata = data.children.filter(function (d) { return (d.step <= 2)}); This just returns the unmodified nested object, even if I put value of filter to 1. does .filter work on nested objects or do I need to roll my own function here, advise and correct code appreciated. cjm

  • Only variables can be passed by reference

    - by zaf
    I had the bright idea of using a custom error handler which led me down a rabbit hole. Following code gives (with and without custom error handler): Fatal error: Only variables can be passed by reference function foo(){ $b=array_pop(array("a","b","c")); return $b; } print_r(foo()); Following code gives (only with a custom error handler): (2048) Only variables should be passed by reference function foo(){ $a=explode( '/' , 'a/b/c'); $c=array_pop(array_slice($a,-2,1)); return $c; } print_r(foo()); The second one worries me since I have a lot of 'compact' code. So, I either ditch the bright idea of using a custom error handler (to improve my logging module) or expand all my code. Anyone with better ideas? Also, WTF?

  • using multi-markers with multi info-windows

    - by mohsen
    I have an array of info-windows corresponding to an array of markers. Now, I have a problem, I use the below code to generate an info-window, when clicking on the marker all the markers disappear unless one, also when I click on that marker there is no info-window come out. What is the wrong with my code ? or what shall I do ? Any answer will be very appreciated, Thanks in advance. This code is inside a for loop: infoWindoArray[i][j] = new google.maps.InfoWindow({ content:"Lat: "+this.position.lat() + "\nLng: " + this.position.lng() + "\n"+ this.customInfo, }); google.maps.event.addListener(AllMarkers[i][j], 'click', (function(x) { return function() {infoWindoArray[i][j].open(map,AllMarkers[i][j]);} })(x));

  • Toggle 1 <div> at a time with Image Changing using JQuery

    Please see this site: http://www.sensationsskin.com/site10/treatments/skin-care.html I've got it working, but am wanting the "+" to change to the "-" (expandbutton-close.gif). I'm using CSS right now to pull up the image, but I think I need to incorporate it into the JQuery code? <script type="text/javascript"> $(document).ready(function(){ //hide the all of the element with class msg_body $(".msg_body").hide(); //toggle the componenet with class msg_body $(".msg_head").click(function(){ if ( $(this).next(".msg_body").is(':visible') ) { $(".msg_body").hide(); } else { $(".msg_body").hide(); $(this).next(".msg_body").slideToggle(450); } }); }); </script>

  • java System.nanoTime is really slow. Is it possible to implement a high performance java profiler?

    - by willpowerforever
    I did a test and found the overhead of a function call to System.nanoTime() is at least 500 ns on my machine. Seemed that it is very hard to have a high performance java profiler. For enterprise software, suppose a function takes about 350 seconds and has 12,500,000,000 times of method calls. Therefore, the number of calls to System.nanoTime() is: 12,500,000,000 * 2 = 25,000,000,000 (one for start timestamp, one for end timestamp) And the overhead of System.nanoTime in total is: 500 ns * 25,000,000,000 = 500 * 25000 s = 12500000s. Note: all data from real case. Any better way to acquire the timestamp?

  • Name of several objects that have the same type

    Lets assume we have a class car. How would You name parameters of function that takes two different cars? void Race(Car first, Car second); or maybe void Race(Car car1, Car car2); The same situation with function that takes car and list of cars as a parameters. I'm used to name 'cars' for list of cars, so it is inconvenient to use names like: void Race(Car car, List<Car> cars); Any suggestions about names?

  • Hashing a python method to regenerate output when method is modified

    - by Seth Johnson
    I have a python method that has a deterministic result. It takes a long time to run and generates a large output: def time_consuming_method(): # lots_of_computing_time to come up with the_result return the_result I modify time_consuming_method from time to time, but I would like to avoid having it run again while it's unchanged. [Time_consuming_method only depends on functions that are immutable for the purposes considered here; i.e. it might have functions from Python libraries but not from other pieces of my code that I'd change.] The solution that suggests itself to me is to cache the output and also cache some "hash" of the function. If the hash changes, the function will have been modified, and we have to re-generate the output. Is this possible or a ridiculous idea? If this isn't a terrible idea, is the best implementation to write f = """ def ridiculous_method(): a = # # lots_of_computing_time return a """ , use the hashlib module to compute a hash for f, and use compile or eval to run it as code?
