  • How do i close a socket after a timeout in node.js?

    - by rramsden
    I'm trying to close a socket after a connection times out after 1000ms. I am able to set a timeout that gets triggered after a 1000ms but I can't seem to destroy the socket... any ideas? var connection = http.createClient(80, 'localhost'); var request = connection.request('GET', '/somefile.xml', {'host':'localhost'}); var start = new Date().getTime(); request.socket.setTimeout(1000); request.socket.addListener("timeout", function() { request.socket.destroy(); sys.puts("socket timeout connection closed"); }); request.addListener("response", function(response) { var responseBody = []; response.setEncoding("utf8"); response.addListener("data", function(chunk) { sys.puts(chunk); responseBody.push(chunk); }); response.addListener("end", function() { }); }); request.end(); returns socket timeout connection closed node.js:29 if (!x) throw new Error(msg || "assertion error"); ^ Error: assertion error at node.js:29:17 at Timer.callback (net:152:20) at node.js:204:9

  • cURL Affects Cookie Retrieval in PHP?

    - by CJ
    I'm not sure if I'm asking this properly. I have two PHP pages located on the same server. The first PHP page sets a cookie with an expiration and the second one checks to see if that cookie was set. if it is set, it returns "on". If it isn't set, it returns "off". If I just run the pages like "www.example.com/set_cookie.php" AND "www.example.com/is_cookie_set.php" I get an "on" from is_cookie_set.php. Heres the problem, on the set_cookie.php file I have a function called is_set. This function executes the following cURL and returns the contents ("on" or "off"). Unfortunately, the contents are always returned as "off". however, if I check the file manually ("www.example.com/is_cookie_set.php") I can see that the cookie was set. Heres the function : <?php function is_set() { $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://example.com/is_cookie_set.php'); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $contents = curl_exec ($ch); curl_close ($ch); echo $contents; } ?> Please note, I'm not using cURL to GET or SET cookies, only to check a page that checks if the cookie was set. I've looked into CURLOPT_COOKIEJAR, and CURLOPT_COOKIEFILE, but I believe those are for setting cookies via cURL and I don't want to do this.

  • jQuery - Compatibility Problem with Internet Explorer 7 and Opera

    - by Marius
    Hello there, I have this counter which counts + 1 every time somebody shares content from the site. When it happens, the social icon that was clicked will bounce. It works in Firefox,Chrome, IE8, and Opera, however the bouncing animation is wrong in opera. $.fn.countExternal = function(animSpeed, num) { // for each counter this.each(function(){ // select all the digit containers var span = $(this).children(); // count the num of digit containers var len = $(span).length; // get the current count u = $(span).text(); // copy variable and add increment(s) v = num + ''; // foreach digit container... for (i=v.length - 1; i >= 0; i--) { // ...check which digits are not affected by the increment(s) if (v.charAt(i) == u.charAt(i)) { break; } } // slice from the total number of digit containers the digits containers which needs updating. slce = len - (v.length - (i + 1)) var updates = $(span).slice(slce); // loop through each digit container and fade out ... $(updates).fadeTo(animSpeed, 0,function(){ $(updates).each(function(index){ f = i + 1 + index; // ...then pick the right digit and update the digit... $(this).text(v.charAt(f)); // ...before fading back in. Cycle complete. $(this).fadeTo(animSpeed, 1); }); }); }); }; }) (jQuery); Demo (NSFW) is here (look underneath the social sharing icons). Any idea how I can solve the IE, and possibly the Opera compatibility problem? Thank you for your time.

  • Why is my long polling code for a notification system not updating in real time? PHP MYSQL

    - by tjones
    I am making a notification system similar to the red notification on facebook. It should update the number of messages sent to a user in real time. When the message MYSQL table is updated, it should instantly notify the user, but it does not. There does not seem to be an error inserting into MYSQL because on page refresh the notifications update just fine. I am essentially using code from this video tutorial: http://www.screenr.com/SNH (which updates in realtime if a data.txt file is changed, but it is not written for MYSQL like I am trying to do) Is there something wrong with the below code: **Javascript** <script type="text/javascript"> $(document).ready(function(){ var timestamp = null; function waitForMsg(){ $.ajax({ type: "GET", url: "getData.php", data: "userid=" + userid, async: true, cache: false, success: function(data){ var json = eval('(' + data + ')'); if (json['msg'] != "") { $('.notification').fadeIn().html(json['msg']); } setTimeout('waitForMsg()',30000); }, error: function(XMLHttpRequest, textStatus, errorThrown){ setTimeout('waitForMsg()',30000); } }); } waitForMsg(); </script> <body> <div class="notification"></div> **PHP*** <?php if ($_SERVER['REQUEST_METHOD'] == 'GET' ) { $userid = $_GET['userid']; include("config.php"); $sql="SELECT MAX(time) FROM notification WHERE userid='$userid'"; $result = mysql_query($sql); $row = mysql_fetch_assoc($result); $currentmodif = $row['MAX(time)']; $s="SELECT MAX(lasttimeread) FROM notificationsRead WHERE submittedby='$userid'"; $r = mysql_query($s); $rows = mysql_fetch_assoc($r); $lasttimeread = $rows['MAX(lasttimeread)']; while ($currentmodif <= $lasttimeread) { usleep(10000); clearstatcache(); $currentmodif = $row['MAX(time)']; } $response = array(); $response['msg'] = You have new messages; echo json_encode($response); } ?>

  • I have a bunch of template parameters that I want to hide from my users. How can I do this?

    - by Alex
    I have a superclass which is defined in terms of a few internal types it uses. Subclassing is performed as so: template <class InternalType1, class InternalType2> class Super { ... } class Sub : Super <interalTypeClass1, interalTypeClass2> { ... } But when I want to write a function that takes a pointer to the superclass, this happens : template <class InternalType1, class InternalType2> void function(Super<InternalType1, InternalType2>* in) { ... } The user really shouldn't know anything about the inside classes, and should really just concern himself with the use of the function. Some of these template lists become very very large, and expecting the user to pass them every time is wasteful, in my opinion. Any suggestions? EDIT: The function needs to know the internal types in use, so unless there is a way to access template types at compile time, I think there is no solution? Potential solution: Have each class do the following: #define SubTemplateArgs <SubTypeName, SubInternalType1, SubInternalType2> ?

  • Is Safari on iOS 6 caching $.ajax results?

    - by user1684978
    Since the upgrade to iOS 6, we are seeing Safari's web view take the liberty of caching $.ajax calls. This is in the context of a PhoneGap application so it is using the Safari WebView. Our $.ajax calls are POST methods and we have cache set to false {cache:false}, but still this is happening. We tried manually adding a timestamp to the headers but it did not help. We did more research and found that Safari is only returning cached results for web services that have a function signature that is static and does not change from call to call. For instance, imagine a function called something like: getNewRecordID(intRecordType) This function receives the same input parameters over and over again, but the data it returns should be different every time. Must be in Apple's haste to make iOS 6 zip along impressively they got too happy with the cache settings. Has anyone else seen this behavior on iOS 6? If so, what exactly is causing it? The workaround that we found was to modify the function signature to be something like this: getNewRecordID(intRecordType, strTimestamp) and then always pass in a timestamp parameter as well, and just discard that value on the server side. This works around the issue. I hope this helps some other poor soul who spends 15 hours on this issue like I did!

  • Convert VBA to VBS

    - by dnLL
    I have a little VBA script with some functions that I would like to convert to a single VBS file. Here is an example of what I got: Private Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As Any, ByVal lpDefault As String, ByVal lpReturnedString As String, ByVal nSize As Long, ByVal lpFileName As String) As Long Private Function ReadIniFileString(ByVal Sect As String, ByVal Keyname As String) As String Dim Worked As Long Dim RetStr As String * 128 Dim StrSize As Long Dim iNoOfCharInIni As Integer Dim sIniString, sProfileString As String iNoOfCharInIni = 0 sIniString = "" If Sect = "" Or Keyname = "" Then MsgBox "Erreur lors de la lecture des paramètres dans " & IniFileName, vbExclamation, "INI" Access.Application.Quit Else sProfileString = "" RetStr = Space(128) StrSize = Len(RetStr) Worked = GetPrivateProfileString(Sect, Keyname, "", RetStr, StrSize, IniFileName) If Worked Then iNoOfCharInIni = Worked sIniString = Left$(RetStr, Worked) End If End If ReadIniFileString = sIniString End Function And then, I need to use this function to put some values in strings. VBS doesn't seem to like any of my var declaration ((Dim) MyVar As MyType). If I'm able to adapt that code to VBS, I should be able to do the rest of my functions too. How can I adapt/convert this to VBS? Thank you.

  • No results are returned when using Flickr JSON request

    - by Martijn1981
    I'm still fairly new to AJAX and I'm experimenting with Twitter and Flickr. Twitter is working fine so far, but I've run into some issues with the Flickr API. I'm getting no results back. The URL seems to be working fine and I'm pointing to the right object containing the array ('items'). Can anybody tell me what I'm doing wrong please? Thanks! $('#show_pictures').click(function(e){ e.preventDefault(); $.ajax({ url: 'http://api.flickr.com/services/feeds/photos_public.gne?format=json&jsoncallback=?&tags=home', dataType: 'jsonp', success: function(data) { $.each(data.items, function(i, item){ $('<div></div>') .hide() .append('<h1>'+item.title+'</h1>') .append('<img src="'+item.media.m+'" >') .append('<p>'+item.description+'</p>') .appendTo('#results') .fadeIn(); }) }, error: function(data) { alert('Something went wrong!'); } }); });

  • How do I use cookies to store users' recent site history(PHP)?

    - by ggfan
    I decided to make a recent view box that allows users to see what links they clicked on before. Whenever they click on a posting, the posting's id gets stored in a cookie and displays it in the recent view box. In my ad.php, I have a definerecentview function that stores the posting's id (so I can call it later when trying to get the posting's information such as title, price from the database) in a cookie. How do I create a cookie array for this? **EXAMPLE:** user clicks on ad.php?posting_id='200' //this is in the ad.php function definerecentview() { $posting_id=$_GET['posting_id']; //this adds 30 days to the current time $Month = 2592000 + time(); $i=1; if (isset($posting_id)){ //lost here for($i=1,$i< ???,$i++){ setcookie("recentviewitem[$i]", $posting_id, $Month); } } } function displayrecentviews() { echo "<div class='recentviews'>"; echo "Recent Views"; if (isset($_COOKIE['recentviewitem'])) { foreach ($_COOKIE['recentviewitem'] as $name => $value) { echo "$name : $value <br />\n"; //right now just shows the posting_id } } echo "</div>"; } How do I use a for loop or foreach loop to make it that whenever a user clicks on an ad, it makes an array in the cookie? So it would be like.. 1. clicks on ad.php?posting_id=200 --- setcookie("recentviewitem[1]",200,$month); 2. clicks on ad.php?posting_id=201 --- setcookie("recentviewitem[2]",201,$month); 3. clicks on ad.php?posting_id=202 --- setcookie("recentviewitem[3]",202,$month); Then in the displayrecentitem function, I just echo however many cookies were set? I'm just totally lost in creating a for loop that sets the cookies. any help would be appreciated

  • Can a lambda can be used to change a List's values in-place ( without creating a new list)?

    - by Saint Hill
    I am trying to determine the correct way of transforming all the values in a List using the new lambdas feature in the upcoming release of Java 8 without creating a **new** List. This pertains to times when a List is passed in by a caller and needs to have a function applied to change all the contents to a new value. For example, the way Collections.sort(list) changes a list in-place. What is the easiest way given this transforming function and this starting list: String function(String s){ return [some change made to value of s]; } List<String> list = Arrays.asList("Bob", "Steve", "Jim", "Arbby"); The usual way of applying a change to all the values in-place was this: for (int i = 0; i < list.size(); i++) { list.set(i, function( list.get(i) ); } Does lambdas and Java 8 offer: an easier and more expressive way? a way to do this without setting up all the scaffolding of the for(..) loop?

  • Read data from form

    - by Superhuman
    This is a strange question, I've never tried to do this before. I have a repetitive process requiring that I copy and paste data from text boxes in one program into another program for further processing. I'd like to automate this process using VB .NET. The application from which the data is gathered isn't mine, so I don't have ActiveX-like access to its controls. How would you write an application to gain access to a form from another application, to be able to find the controls on the form, and gather the values from them? Just experimenting, I've used the following code. This resulted in only the name of the form to which this code belongs. It didn't find the names of any other forms I have open, and I have a lot open to choose from. This is frustrating because it's only step one of what I'll need to do to make my life easier... Public Declare Function EnumWindows Lib "user32" (ByVal lpEnumFunc As CallBack, ByVal lParam As Integer) As Integer Public Delegate Function CallBack(ByVal hwnd As IntPtr, ByVal lParam As IntPtr) As Boolean Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim cb As New CallBack(AddressOf MyCallBack) EnumWindows(cb, 8) End Sub Public Function MyCallBack(ByVal hwnd As Long, ByVal lparam As Long) As Boolean Dim frm As System.Windows.Forms.Control frm = System.Windows.Forms.Form.FromHandle(hwnd) If frm Is Nothing Then Return True If frm.Text <> "" Then TextBox1.Text += frm.Text & ", " End If Return True End Function Does anyone have a recommendation?

  • jquery focusin() and preventing bubbling.

    - by DA
    I'm showing a div via an onclick event. If you click outside the div, I want to hide it. To do so, I'm binding a one time click event on the body: $('body').one('click.myDivPopup', function(e) { ...close my div... }); Within the div itself, I tell it to not propogate events so that actually clicking within the div won't trigger a click on the body: $myDiv.click(function(e){e.stopPropagation()}); This works fine as intended. I also want to hide the div if one tabs out of the div. My thinking was that in that scenario, I could use a focusin event on the body: $('body').one('focusin.myDivPopup', function(e) { ...close my div... }); Again, I don't want the events to bubble out of the div itself, so added this: $myDiv.focusin(function(e){e.preventDefault()}); This does NOT work. Changing focus within elements within myDiv triggers the focusin event on the body. Is this maybe a bug in jQuery? If so is there a better way to accomplish this?

  • I need to sort the facets that come back from SOLR by relevancy

    - by Pinguthepenguin
    I have within my SOLR index song objects which belong to a higher level album object. An example is shown below: <song> <album title>Blood Sugar Sex Magic</album title> <song title>Under the Bridge</song title> <description>A sad song about junkies</description> </song> What I can do at the moment is create a facet on the album title so that a search on songs will also show me what albums contain hits for that keyword. The default behaviour for SOLR is that the facets are shown in the order of most hits to least. However what I want to achieve is the facet list to be sorted according to the relevancy of the top hit for that album. For example a search on the word "sad" may show a facet with one hit for "Blood Sugar Sex Magic" and there may also be an album called "Sad Clown songs" where there are 10 hits. "Sad clown songs" will show as the first facet even though it may be that "Under the bridge" comes up as the most relevant song. My question is how can I get all the facets back but then have them ordered by the relevancy of the songs within them? If I would need to change or extend some underlying SOLR code what would that be? Thanks in advance.

  • python matrices - list index out of range

    - by user1888493
    I am writing a function, that takes a matrix as input, such as the one below. Then the it returns the matrix' inverse, where all the 1s are changed to 0s and all the 0s changed to 1s, while keeping the diagonal from top left to bottom right 0s. An example input: g1 = [[0, 1, 1, 0], [1, 0, 0, 1], [1, 0, 0, 1], [0, 1, 1, 0]] the function should output this: g1 = [[0, 0, 0, 1], [0, 0, 1, 0], [0, 1, 0, 0], [1, 0, 0, 0]] When I run the program, it raises a list index out of range error. I'm sure this happens, because the loops I have set up are trying to access values that do not exist. But how do I allow an input of unknown row and column size? I only know how to do this with a single list, but a list of lists? Following you see the transforming function, but not the test function that calls it: def inverse_graph(graph): # take in graph # change all zeros to ones and ones to zeros r, c = 0, 0 # row, column equal zero while (graph[r][c] == 0 or graph[r][c] == 1): # while the current row has a value. while (graph[r][c] == 0 or graph[r][c] == 1): # while the current column has a value if (graph[r][c] == 0): graph[r][c] = 1 elif (graph[r][c] == 1): graph[r][c] = 0 c+=1 c=0 r+=1 c=0 r=0 # sets diagonal to zeros while (g1[r][c] == 0 or g1[r][c] == 1): g1[r][c]=0 c+=1 r+=1 return graph

  • What does an object look like in memory?

    - by NeilMonday
    This is probably a really dumb question, but I will ask anyway. I am curious what an object looks like in memory. Obviously it would have to have all of its member data in it. I assume that functions for an object would not be duplicated in memory (or maybe I am wrong?). It would seem wasteful to have 999 objects in memory all with the same function defined over and over. If there is only 1 function in memory for all 999 objects, then how does each function know who's member data to modify (I specifically want to know at the low level). Is there an object pointer that gets sent to the function behind the scenes? Perhaps it is different for every compiler? Also, how does the static keyword affect this? With static member data, I would think that all 999 objects would use the exact same memory location for their static member data. Where does this get stored? Static functions I guess would also just be one place in memory, and would not have to interact with instantiated objects, which I think I understand.

  • Interval arithmetic to correctly deal with end of month - Oracle SQL

    - by user2003974
    I need a function which will do interval arithmetic, dealing "correctly" with the different number of days in a month. For my version of "correctly" - see below! First try select to_date('31-May-2014') + interval '1' months from dual This returns an error, because there is no 31st June. I understand that this behaviour is expected due to the ANSI standard. Second try select add_months(to_date('31-May-2014'),1) from dual This correctly (in my use case) returns 30th June 2014, which is great. BUT select add_months(to_date('28-Feb-2014'),1) from dual returns 31st March 2014, when I want 28th March 2014. Background This has to do with legal deadlines. The deadlines are expressed in law as a number of months (say, 3) from a base date. If the base date is last day of the month and three months later the month is longer, then the deadline does NOT extend to the end of the longer month (as per the add_months function). However, if the base date is last day of the month and three months later the month is shorter, then the deadline expires on the last day of the shorter month. Question Is there a function that does what I need? I have intervals (year to month) stored in a table, so preferably the function would look like: add_interval_correctly(basedate DATE, intervaltoadd INTERVAL YEAR TO MONTH)

  • JQUERY - how Two elements - IMG - DIV when hover over IMG show/hide the DIV - added with hover hide/

    - by Jan Fosgerau
    Im very new to the wonder that is jquery. and i just figure out how to make my img buttons show/hide with a opacity difference (as such) <script type="text/javascript"> <![CDATA[ $(".ExcommKnap").mouseover(function () { $(this).stop().fadeTo('fast', 0.5, function(){}) }); $(".ExcommKnap").mouseout(function () { $(this).stop().fadeTo('fast', 1.0, function(){}) }); ]]> </script> which is good and all. but i also need to make the button when hovered over show text just above it that is specific to that button. i made these here elements that are looped in a for each. <div style="top:10px; width:755px;text-align:right; position:absolute; "> <div id="Page-{@id}" class="headlinebox"> <xsl:value-of select="@nodeName"/> </div> </div> <a href="{umbraco.library:NiceUrl(@id)}"> <img class="ExcommKnap" src="{$media/data[@alias='umbracoFile']}" /> </a> i need to make the individual text appear when hovered over its button. hence i have the id="page-{@id}" looped out along and need to get this place in the jquery code i presume. so when i hover over a img class="ExcommKnap" it makes the correct text visible. But i need the div id="page-{id}" to be invisible to begin with on pageload and then visible when its button is being hovered over. can anyone help ?

  • Error while sending image through ajax to WCF

    - by Samar Rizvi
    Here is my form: <form id="register" enctype="multipart/form-data"> <input type="text" name="first_name" placeholder="First Name" id="first_name" /> <input type="text" name="last_name" placeholder="Last Name" id="last_name" /> <input type="text" name="input_email" placeholder="Confirm your email" id="input_email" class="loginEmail" /> <input type="password" name="input_password" placeholder="Password" id="input_password" class="loginPassword" /> <input type="password" name="repeat_password" placeholder="Repeat password" id="repeat_password" class="loginPassword" /> <input type="file" name="image_file" id="image_file" /> <div class="logControl"> <div class="memory"></div> <input type="submit" name="submit" value="Register" class="buttonM bBlue" id="register_submit"/> <div class="clear"></div> </div> <p><h3>Or click <a href="login.html">here</a> to login</h3></p> </form> Here is jquery call that I make: function WCFJSON() { $(".memory").html('<img src="images/elements/loaders/7s.gif" />'); Data = new FormData($('form')[0]); $.ajax({ type: 'POST', //GET or POST or PUT or DELETE verb url: "WCFService/Service.svc/Register", // Location of the service data: Data, //Data sent to server async:false, cache:false, contentType: false, // content type sent to server dataType: DataType, //Expected data format from server processdata: false, //True or False success: function(msg) {//On Successfull service call ... }, error: ...// When Service call fails }); } $(document).ready(function(){ $("#register").submit(function(){ $('#input_password').val(CryptoJS.MD5($('#input_password').val())); $('#repeat_password').val(CryptoJS.MD5($('#repeat_password').val())); WCFJSON(); return false; }); }); Now when I submit the form , page refreshes with get elements in the url. But if I remove the file input from the form, jquery works fine.

  • ajax on parked domain

    - by Daryl
    I'm currently writing this jquery and for some reason (I don't know why) it works on the normal domain, but on the parked domain it doesn't. Normal domain - http://www.thefinishedbox.com Parked domain - http://www.tfbox.com If you scroll down to the colony news and hit the click me link you'll see it will retrieve data via jquery ajax on the Normal domain, but on the parked domain it wont. Here is the jQuery code I have so far (its pretty standard): $(function() { $.ajaxSetup({ cache: false }); var ajax_load = "Load me plz"; // load() functions var loadUrl = "http://thefinishedbox.com/wp-content/themes/tfbox-beta/test.php"; $('.overlay').css({ opacity: '0' }); $('.toggle').click(function() { $('.overlay').css({ display: 'block' }).animate({ opacity: '1' }, 300); $(".overlay .content").html(ajax_load).load(loadUrl); return false; }); $('.close').click(function() { $('.overlay').animate({ opacity: '0' }, 300); $('.overlay').queue(function() { $(this).css({ display: 'none' }); $(this).dequeue(); }); return false; }); I'm a complete noob when it comes to ajax so any help would be massivly appreciated.
