  • mysql_close(): supplied argument is not a valid MySQL-Link resource

    - by Illes Peter
    Here's what I'm trying to do: I've got a db.php file that does all the db manipulation. It has 2 static methods, connect and deconnect. In my other file i simply use db::connect() and db::deconnect(). The mysql_close($con) in the deconnect method just doesn't know who $con is. Since I don't want to instantiate my class static is the only way to go. Declaring 'private $con' in class db doesn't seem to have an effect. Any ideas? class db { public static function connect() { $dbData = parse_ini_file($_SERVER['DOCUMENT_ROOT'].'/config.ini'); $con = mysql_connect($dbData['host'],$dbData['user'],$dbData['pass']); $db = mysql_select_db($dbData['db']); if ((!$con) || (!$db)) return 0; else return 1; } public static function deconnect() { mysql_close($con); } }

  • Interesting Row_Number() bug

    - by Joel Coehoorn
    I was playing with the Stack Exchange Data Explorer and ran this query: http://odata.stackexchange.com/stackoverflow/q/2828/rising-stars-top-50-users-ordered-on-rep-per-day Notice down in the results, rows 11 and 12 have the same value and so are mis-numbered, even though the row_number() function takes the same order by parameter as the query. I know the correct fix here is to specify an additional tie-breaker column in the order by clauses, but I'm more curious as to why/how the row_number() function returned different results on the same data? If it makes a difference anywhere, this runs on Azure.

  • Initializing and accessing a pointer from an array of pointers

    - by idealistikz
    Suppose I have the following: void **Init(int numElems) { //What is the best way to intialize 'ptrElems' to store an array of void *'s? void **ptrElems = malloc(numElems * sizeof(void *)); return ptrElems; } //What is the best way to return a pointer pointing at the index passed as a parameter? void **GetPtr(void **ptrElems, int index) { void **elem = elems + (index * sizeof(void *)); return elem; } First, what is the best way to intialize 'ptrElems' to store an array of pointers? I use malloc because assigning it to an array will not persist after the end of the function. Second, what is the best way to point to the pointer at the specified index? I tried typecasting the first line of the 'GetPtr' function to ensure proper pointer arithmetic, but I receive the warning, 'initialization from incompatible pointer type'. Is it necessary to typecast?

  • Problems using the Razor model when creating my knockout ViewModel

    - by Emil Kantis
    I'm having problems with using the Model in a javascript call when setting up my knockout VM.. @model List<AdminGui.Models.Domain> <script src="http://ajax.aspnetcdn.com/ajax/knockout/knockout-2.2.1.js" type="text/javascript"></script> <script type="text/javascript"> function ViewModel() { var self = this; self.domains = ko.observableArray( ko.utils.arrayMap(@Model, function(item) { return new Domain(item.guid, item.description, item.namespaces); })); } I get a syntax error on @Model in the ko.utils.arrayMap call. I suspect it might be my Razor-fu that is lacking... :)

  • "Intercepting" user input into text box and removing it

    - by James P
    I have a text box that I would like to do some validation on. At the moment I have this code: function updateChanger() { // Validate input var likeMessage = validateInput($("#like").val()); alert(likeMessage); } function validateInput(input) { input = input.replace(/[^a-zA-Z0-9:\(\/\)\s\.,!~]/g, ""); return input; } This successfully trims out unwanted characters in the likeMessage variable, but the character still gets entered into the text box. I would like to stop that from happening. I know it will have something to do with $("#like").val() but the only thing I can think of is just chopping off the end character from the text box value, would this suffice? Thanks for any help!

  • thumbs.db messing up my upload routine

    - by Scott B
    I'm getting the following error while uploading a zip archive. Warning: ZipArchive::extractTo(C:\xampplite\htdocs\testsite/wp-content/themes/mytheme//styles\mytheme/Thumbs.db) [ziparchive.extractto]: failed to open stream: Permission denied in C:\xampplite\htdocs\testsite\wp-content\themes\mythem\uploader.php on line 17 The thing I can't quite figure is that I don't see a thumbs.db file in either the zip archive or the destination folder that was created (the upload still processes, I just get these errors). The function is below, line 17 is commented... function openZip($file_to_open) { global $target; $zip = new ZipArchive(); $x = $zip->open($file_to_open); if($x === true) { $zip->extractTo($target); //this is line 17 $zip->close(); unlink($file_to_open); } else { die("There was a problem. Please try again!"); } }

  • show the list of usernames inside a div

    - by Mr_Green
    I am new to jQuery. In my project, I created one Class User in which the code is as shown below: static ConcurrentDictionary<string, User> _users = new ConcurrentDictionary<string, User>(); // // some function to add values to _users list // public List<User> GetConnectedUsers() { return _users.Values.ToList(); } I want to show this list of values in div #showUsernames. How to do this by using jQuery? I tried the below which is not showing anything /*display your contacts*/ $('#showUsernames').append(function(){ chat.server.getConnectedUsers(); }); where chat.server(signalr) calls the server-side code(Chat class).. I think the solution has nothing to do with signalr. If the above description is not enough then you can go through my code here

  • In MAYA 2009, is it possible to capture the cube rotate event?

    - by Rahul2047
    I need to call a function ( Maya-Python ) based on cube rotationX. For that I have to capture the event, programmatically. I tried using while loop but It stucks in the loop, Nothing can be done in that time. I tried theading (python), still same. Can it be done this or other way? If yes, How? Maya 2009 in Windows XP Some failed code references: import maya.cmds as cmds while (count < 90): lock = cmds.getAttr('pCube1.rotateX',lock=False) print lock count = count + 1 Here Python wise: #!/usr/bin/python import thread import time # Define a function for the thread def cubeRotateX( threadName, delay): count = 0 while count < 5: time.sleep(delay) count += 1 try: thread.start_new_thread( cubeRotateX, ("Thread-1", 2, ) ) except: print "Error: unable to start thread" while 1: pass

  • Use deployJava.js to check for/automatically install latest JRE version for web applet

    - by Pryo
    I'd like to use the deployJava.js tool to have Java automatically detect the currently installed JRE and install an updated version if necessary. My initial impression when reading about deployJava.js was that it would do this out of the box when you simply set a version number as a function parameter for the "runApplet" function. But this has never seemed to work. Is it even possible to do this, and if so, how? Here is my current code for launching my applet: <script type="text/javascript" src="https://www.java.com/js/deployJava.js"></script> <script type="text/javascript"> var attributes = {id:"applet", name:"TheApplet", code:"TheApplet"}; var parameters = {jnlp_href: "http://localhost/TheApplet.jnlp"}; deployJava.runApplet(attributes, parameters, "1.6.0_31"); </script> Thanks

  • Need help with jQuery UI Accordion navigationFilter option

    - by theJBRU
    I'm building an accordion for navigation. Each section of the accordion has a set of links. The firing code looks like this: $(document).ready(function() { $(".selector").accordion({ collapsible: true, active: false, navigation: true }); }); This all worked fine and dandy until one of the links in each set was edited to point to a single file, call it foo.html. So now if you navigate to foo.html, the location.href matches every section of the accordion (since each section has a link to it) and that opens all the sections, defeating the purpose of the accordion. So I'm pretty sure I need to use the navigationFilter option but I've googled the living hell out of it and haven't found any examples of how to build the function associated with it. Help me, Stack Overflow!

  • does the condition after && always get evaluated

    - by brett
    I have this if statement that tests for the 2 conditions below. The second one is a function `goodToGo() so I want to call it unless the first condition is already true $value = 2239; if ($value < 2000 && goodToGo($value)){ //do stuff } function goodToGo($value){ $ret = //some processing of the value return $ret; } My question is about the 2 if conditions $value < 2000 && goodToGo($value). Do they both get evaluated or does the second one only get evaluated when the first one is true? In other words, are the following 2 blocks the same? if($value < 2000 && goodToGo($value)) { //stuff to do } if($value < 2000) { if (goodToGo($value)){ //stuff to do } }

  • How to create a non-persistent Elixir/SQLAlchemy object?

    - by siebert
    Hi, because of legacy data which is not available in the database but some external files, I want to create a SQLAlchemy object which contains data read from the external files, but isn't written to the database if I execute session.flush() My code looks like this: try: return session.query(Phone).populate_existing().filter(Phone.mac == ident).one() except: return self.createMockPhoneFromLicenseFile(ident) def createMockPhoneFromLicenseFile(self, ident): # Some code to read necessary data from file deleted.... phone = Phone() phone.mac = foo phone.data = bar phone.state = "Read from legacy file" phone.purchaseOrderPosition = self.getLegacyOrder(ident) # SQLAlchemy magic doesn't seem to work here, probably because we don't insert the created # phone object into the database. So we set the id fields manually. phone.order_id = phone.purchaseOrderPosition.order_id phone.order_position_id = phone.purchaseOrderPosition.order_position_id return phone Everything works fine except that on a session.flush() executed later in the application SQLAlchemy tries to write the created Phone object to the database (which fortunatly doesn't succeed, because phone.state is longer than the data type allows), which breaks the function which issues the flush. Is there any way to prevent SQLAlchemy from trying to write such an object? Ciao, Steffen

  • I have a ConnectException that isn't being caught for some reason

    - by aakbari1024
    I'm working on an Android application that uses sockets. I have a function called initializeStreams() which opens the socket and attempts a connection. This function throws a ConnectException if the connection could not be established. But for some reason, in the code that calls initializeStreams(), which has a catch block for ConnectException, the log prints out its own stack trace for the exception instead of going to the catch block. The catch block is never reached at all, even though the exact exception is being thrown. Here's the code: The try block: try { initializeStreams(); /* drivesList = new ArrayList<String>(); drivesList = enumerateDrives();*/ } catch (ConnectException e) { //Log.i(TAG, "caught connect exception"); /*loadingProgress.dismiss(); retryConnection();*/ } initializeStreams(): public void initializeStreams() throws ConnectException { try { Log.i(TAG, "Attempting to connect"); requestSocket = new Socket(SERVER_ADDR, PORT); /* other code */ } catch (IOException e) { e.printStackTrace(); } I can't figure this out, so any help would be much appreciated. }

  • $.ajax working with Firefox, not IE

  • Modulation of adding new Strings -> Method calls.

    - by guesswork
    If I have a program that does the following: if(input=='abc'){do x} if(input=='def'){do y} In the future, I may want to add another piece of code like so: if(input=='ghy'){do x} As you can see, I am adding a new 'if' statement for a different conditional BUT using the SAME function X. The code in future has potential to have lots of different IF statements (or switches) all of which are comparing a string vs a string and then performing a function. Considering the future expansion, I was wondering if there is a possible 'neater', 'modular' way of achieving the same results. It's a shame I can't combine the String with a Method call in a hashtable (String, method) in Java. That way I could just store any new procedures inside a hashtable and grab the relevant method for that String. Any ideas? Thank you

  • XPath conditional text node selection

    - by Reinderien
    Hi there. I need to construct an xpath string to select all descendants of a certain table with these conditions: The table is a descendant of a form with a specific action attribute value. The selected descendants are text nodes. The text node content can only contain whitespace. It'll probably look something like: //form[@action = "submit.html"]//table//text()[ ...? ] Any tips would be appreciated. Thanks. Edit: For clarity, here is my current (working) compromise: function KillTextNodes(rootpath) { XPathIterate(rootpath + '//text()', function(node) { var tagname = node.parentNode.tagName; if (tagname != 'OPTION' && tagname != 'TH') Kill(node); }); }

  • Dynamically generating high performance functions in clojure

    - by mikera
    I'm trying to use Clojure to dynamically generate functions that can be applied to large volumes of data - i.e. a requirement is that the functions be compiled to bytecode in order to execute fast, but their specification is not known until run time. e.g. suppose I specify functions with a simple DSL like: (def my-spec [:add [:multiply 2 :param0] 3]) I would like to create a function compile-spec such that: (compile-spec my-spec) Would return a compiled function of one parameter x that returns 2x+3. What is the best way to do this in Clojure?

  • How do I use Declarations (type, inline, optimize) in Scheme?

    How do I declare the types of the parameters in order to circumvent type checking? How do I optimize the speed to tell the compiler to run the function as fast as possible like (optimize speed (safety 0))? How do I make an inline function in Scheme? How do I use an unboxed representation of a data object? And finally are any of these important or necessary? Can I depend on my compiler to make these optimizations? thanks, kunjaan.
