  • isReachable in Java doesn't appear to be working quite the way it's supposed to

    - by Rayne
    I'm using Clojure, but I can read Java, so this isn't a Clojure specific question. This doesn't even seem to be working from Java. I'm trying to implement a bit of a 'ping' function using isReachable. The code I'm using is this: (.isReachable (java.net.InetAddress/getByName "www.microsoft.com") 5000) Translated to Java by a good friend of mine: public class NetTest { public static void main (String[] args) throws Exception{ String host = "acidrayne.net"; InetAddress a = InetAddress.getByName(host); System.out.println(a.isReachable(10000)); } } Both of these return false. I suppose I must be doin' it wrong, but Google research is telling me differently. I'm confuzzled!

  • How would I create a VIM or Vi command to delete all text after a certain character for every line i

    - by Jason Down
    Scenario: I have a text file that has pipe (as in the "|" character) delimited data. Each field of data in the pipe delimited fields can be of variable length, so counting characters won't work (or using some sort of substring function... if that even exists in VIM). Is it possible, using VIM / Vi to delete all data from the second pipe to the end of the line for the entire file? There are approx 150,000 lines, so doing this manually would only be appealing to a masochist... e.g. Change the following lines from: 1111|random sized text 12345|more random data la la la|1111|abcde 2222|random sized text abcdefghijk|la la la la|2222|defgh 3333|random sized text|more random data|33333|ijklmnop to: 1111|random sized text 12345 2222|random sized text abcdefghijk 3333|random sized text I'm sure this can be done somehow... I hope. TIA UPDATE: I should have mentioned that I'm running this on Windows XP, so I don't have access to some of the mentioned *nix commands (CUT is not recognized on Windows).

  • What's the best way to call jQuery scripts, in HTML/PHP template, or seperate js file?

    - by j-man86
    StackOverflow is telling me this is a subjective question, but I think it's a matter of fact! I have a number of scripts that I'm using on different parts of my site. In terms of making fewer http requests, I know it's better to combine all of these scripts into one .js file. However, isn't a waste of time for a page to call a .js full of 10 or 15 different functions when it's only using one? The other method I am using is to use PHP conditional statements... <?php if( is_page() ) { > $(document).ready(function(){ ... }); <?php } ?> What's the best method or comination of these methods?

Somebody can help me with this issue ? Thanks !!!!!!!!

  • Php code not executing - dies out when trying to refer to member of static class - no error displaye

    - by Ali
    I'm having some problems with this piece of code. I've included a class declaration and trying to create an object of that class but my code dies out. It doesn't seem to be an include issue as all the files are being included even the files called for inclusion within the class file itself. However the object is not created - I tried to put an echo statement in the __construct function but nothing it just doesn't run infact doesn't create the object and the code won't continue from there - plus no error is reported or displayed and I have error reporting set to E_ALL and display errors set to true WHats happening here :( =============EDIT SOrry I checked again the error is prior to teh object creation thing - it dies out when it tries to refer to a constant in a static class like so: $v = Zend_Oauth::REQUEST_SCHEME_HEADER; THis is the class or part of it - it has largely static functions its the Zend Oauth class: class Zend_Oauth { const REQUEST_SCHEME_HEADER = 'header'; const REQUEST_SCHEME_POSTBODY = 'postbody'; const REQUEST_SCHEME_QUERYSTRING = 'querystring'; // continued LIke I said no error is being reported at all :(

  • jQuery: event that tracks click in browser autocomplete

    - by Fernando
    I have a keyup event on an input. This event works fine for auto complete when you select a value and press enter. But it doesn't work when you click at an auto complete value. Is there an event that i can use in such case? I already tried the change one but it doesn't work. Thanks! Edit: Maybe i was not clear but i am referring to the autocomplete feature that browsers have. I am not trying to build my own. Example: I have the following event: $('.product').keyup(searchByProduct); When user clicks at this input the old values that he already typed shows up ( it's the browser that does this ). If he clicks on one of the values, the function searchByProduct is not called. Which event do i have to register to track this click ( and that the input content has changed )?

  • get all widgets inside an element

    - by peirix
    From the dojo documents on dijit.registry, I see the forEach method accepts a last parameter thisObject. But it doesn't way what that object is. Is it a dijit widget or a dojo object? I want to destroy all widgets inside an element (that will be replaced by AJAX) so they can be parsed again without conflicting id's. dijit.registry.forEach(function(w) { w.destroyRecursive(); }, dojo.byId("ajaxElement")); But this destroys ALL widgets on the page...

  • Question about the mathematical properties of hashes

    - by levand
    Take a commonly used binary hash function - for example, SHA-256. As the name implies, it outputs a 256 bit value. Let A be the set of all possible 256 bit binary values. A is extremely large, but finite. Let B be the set of all possible binary values. B is infinite. Let C be the set of values obtained by running SHA-256 on every member of B. Obviously this can't be done in practice, but I'm guessing we can still do mathematical analysis of it. My Question: By necessity, C ? A. But does C = A?

  • Seperate compilation in C++

    - by Pat Murray
    Suppose you are creating a class with multiple .cpp files (which each contain the implementation of a member function) and have the class' declaration in a .h file. Also, each .cpp file includes the .h file via the include directive. I was told that if you change the implementation of any of the member functions (.cpp files) that you will have to recompile every .cpp file in order to run the program. That is, if I had 5 member functions (each implemented in a .cpp file) and I changed the implementation of 1 of the .cpp files I would have to compile the 1 .cpp file I changed AND the 4 other .cpp files I didn't change in order to correctly run my program. My question, if the previous statement is true, is why is the statement is true? Any insight on this concept would be helpful.

  • Changing the width of dropdown area in flex combobox.

    - by DineshDu
    I have a combobox which gets populated by a remote method. I need to set the dropdownwidth of the combobox to the maximum length of the item in the combobox. I am able to achieve it by the following code. But if the resolution of the screen changes, the result is not similar. Is there any way to find the display width of the text in the dropdown? private function getGroupData(resultEvent:ResultEvent):void{ viewCbx.dataProvider = resultEvent.result as ArrayCollection; var comboDp:ArrayCollection = viewCbx.dataProvider as ArrayCollection; var dropWidth:int = 0; for each(var obj:Object in comboDp){ if(obj.groupName.length > dropWidth){ dropWidth = obj.groupName.length; } } viewCbx.dropdownWidth = dropWidth*6; }

  • How to run shell script with live feedback from PHP?

    - by Highway of Life
    How would I execute a shell script from PHP while giving constant/live feedback to the browser? I understand from the system function documentation: The system() call also tries to automatically flush the web server's output buffer after each line of output if PHP is running as a server module. I'm not clear on what they mean by running it as a 'server module'. I attempted to run the script in the cgi-bin, but either I'm doing it wrong, or that's not what they mean. Example PHP code: <?php system('/var/lib/script_test.sh'); Example shell code: #!/bin/bash echo "Start..." for i in {1..10} do echo "$i..." sleep 1 done echo "Done."

  • Converting delimited string to multiple values in mysql

    - by epo
    I have a mysql legacy table which contains an client identifier and a list of items, the latter as a comma-delimited string. E.g. "xyz001", "foo,bar,baz". This is legacy stuff and the user insists on being able to edit a comma delimited string. They now have a requirement for a report table with the above broken into separate rows, e.g. "xyz001", "foo" "xyz001", "bar" "xyz001", "baz" Breaking the string into substrings is easily doable and I have written a procedure to do this by creating a separate table, but that requires triggers to deal with deletes, updates and inserts. This query is required rarely (say once a month) but has to be absolutely up to date when it is run, so e.g. the overhead of triggers is not warranted and scheduled tasks to create the table might not be timely enough. Is there any way to write a function to return a table or a set so that I can join the identifier with the individual items on demand?

  • How to get a component's parent form in Borland VCL?

    - by nklein
    Hi, I'd like to determine which form a given component belongs to in my application. Neither the Parent nor the Owner property can be assumed to be the form itself, so I can't simply use this. I guess I could just go through the Parent property recursively until I arrive at something derived from TForm, but is there a better way to do this? I used the search function, but couldn't find anything specific to my problem. I'm using Borland C++ Builder, by the way (tagged Delphi because a majority of VCL users seem to write in Delphi, and I read Delphi code just fine). Thanks in advance!

  • OutputDebugString + DebugView = not tabs!

    - by Steve
    I am dumping \t delimited data using using OutputDebugString and then use ex-Sysinternals DebugView to capture it. The problem is that all the data in DebugView appear to be space delimited, hence I need to perfrorm CTRL+H "\x20" "t" to replace spaces with the tabs before I can use it (I really need tab delimited data). Is there anyway to tell DebugView not to replace tabs with spaces? Or maybe there is a better tool available to capture output of the OutputDebugString function? Any ideas are very welcome!

    - by RobertPitt
    Im developing my own framework that uses namespaces. Doctrine is already integrated into my auto loading system and im now at the stage where ill be creating the model system for my application Usually i would create a simple model like so: namespace Application\Models; class Users extends \Framework\Models\Database{} which would inherit all the default database model methods, But with Doctrine im still learning how it all works, as its not just a simple DBAL. I need to understand whats the part of doctrine my classes would extend where i can do the following: namespace Application\Models; class Users Extends Doctrine\Something\Table { public $__table_name = "users"; } And thus within the controller i would be able to do the following: public function Display($uid) { $User = $this->Model->Users->findOne(array("id" => (int)$id)); } Anyone help me get my head around this ?

  • Using opencv in Win32 application for image show

    - by erjik
    Is it possible to output images so that they all will be inside a single window? Before, I used to output data using only opencv functions: cvNamedWindow("Image 1"); cvShowImage("Image 1", img); So I change image, then call: cvShowImage function and so on. But If I want to look at more than one image, then every new image needs its own window to be shown there And what I want is to put every such an output opencv's window inside one big main window. Is it possible to do it? And how?

  • flash.media.Sound.play takes long time to return

    - by Fire Lancer
    I'm trying to play some sounds in my flash project through action script. However for some reason in my code the call to Sound.play takes from 40ms to over 100ms in extreme cases, which is obviously more than enough to be very noticeable whenever a sound is played. This happens every time a sound is played, not just when that sound is first played, so I dont think its because the Sound object is still loading data or anything like that... At the start I have this to load the sound: class MyClass { [Embed(source='data/test_snd.mp3')] private var TestSound:Class; private var testSound:Sound;//flash.media.Sound public function MyClass() { testSound = new TestSound(); } Then im just using the play method of the sound object to play it later on. testSound.play();//seems to take a long time to return This as far as I can tell is following the same process as other Flash programs I found, however none of them seem to have this problem. Is there something that I've missed that would cause the play() method to be so slow?

  • How to make windows media player go to previous song in playlist?

    - by SadSido
    Hi, everyone! I am writing a simple Windows app in c++, that will be able to send commands to windows media player. My problem is that I want my app to move to the previous song in the playlist. IWMPControls::previous() seems to do the job, but its behavior differs from what is written in msdn. In fact this function rewinds current media to the beginning and then (if current position is less than 2-3 seconds) it switches to the previous song. I would like to implement two different buttons (please, don't ask me why :)) - one for rewinding to the beginning, and one - to moving to previous song. Is there any easy way to do this through IWMPControls (or any other WMP-related COM interface)? p.s. I could handle this if I could get the position (index) of the current song in the list. But as far as I read MSDN, it seems to me that there is no easy way to get the current item index from playlist...

  • how so select similarities in MySQL?

    - by mysqllearner
    Currently, I am doing a search function. Lets say in my database, I have this data: Keyword1 Keyword2 Keyword3 Keysomething Key and the user entered: "Key" as the keyword to search. This is my current query: Q1: SELECT * FROM data WHERE (data_string LIKE '$key%' OR data_string LIKE '%$key%' OR data_string LIKE '%$key') Basically, I have 2 questions: How do I sort by (order by) similarity. From above example, I should have "Key" as my first result. My current result is: Keyword1, Keyword2, Keyword3, Keysomething and Key My SQL query only search by the "data_string" column, what if I want to seach others column? Do I need to do something like this: Q2: SELECT * FROM data WHERE (data_string LIKE '$key%' OR data_string LIKE '%$key%' OR data_string LIKE '%$key') OR (data_other LIKE '$key%' OR data_other LIKE '%$key%' OR data_other LIKE '%$key') ...

  • Where should I define custom routes in my ZF 1.10 app?

    - by Ross
    With the new Zend_Application/Zend_Application_Bootstrap classes I'm confused as to where I should be applying my custom routes. For example, at the moment I have one route: protected function _initRouter() { $router = new Zend_Controller_Router_Rewrite; $route = new Zend_Controller_Router_Route('news/:id', array('controller' => 'news', 'action' => 'view')); $router->addRoute('postArchive', $route); } This method is in my Zend_Application_Bootstrap_Bootstrap and is definitely run. The route is also applied in $router. As I see it I could be doing two things wrong - either the wrong place to add these routes, or not adding to the correct router. Can anyone point me in the right direction with this?

  • sending javascript array to external php file using POST

I have spent the last couple days trying to figure this out as well. Can someone please point me in the right direction. current output (from php page) - Array (thats all the page outputs)

Also I have some key bindings to open function declarations which I would like to use with all programming languages. How can this be achieved in gVim? As in, is there a way to maintain a configuration file for each programming language or something of that sort?
