  • Getting jQuery to return an ajax object

    - by japancheese
    Hello, The question title is a bit strange because I'm not exactly sure how to phrase the problem. The issue is that I have many links to which I want to bind a click event with an ajax call, and I'm just looking to refactor some duplicate code into a single area. The links I'm trying to bind an ajax call only have one thing that differentiates them, and that's an id from a previously declared object. So I have lots of code that looks like this: $("a.link").bind('click', function() { id = obj.id; $.ajax({ url: "/set/" + id, dataType: 'json', type: "POST" }) }); I was trying to refactor it into something like this: $("a.link").bind('click', ajax_link(obj.id)); function ajax_link(id) { $.ajax({ url: "/set/" + id, dataType: 'json', type: "POST" }) }); However, as you can imagine, this just actually makes the ajax call when the element is binded with the click event. Is there an easy way to refactor this code so I can extract out the common ajax code into its own function, and hopefully reduce the number of lines of jQuery in my current script?

  • How do I get multimonth plugin of the jQuery datePicker to load with certain dates already selected?

    - by imHavoc
    well im using this script right here: http://www.kelvinluck.com/assets/jquery/datePicker/v2/demo/ and I have a multiMonth plugin and multiple select enabled. I want to be able to on load have certain dates already selected and those dates come from a database I found two possible clues to help me out, but since I have not strictly learned JS yet, I can not made heads or tails. http://www.kelvinluck.com/assets/jquery/datePicker/v2/demo/renderCalendarBankHolidays.html http://www.kelvinluck.com/assets/jquery/datePicker/v2/demo/datePickerDefaultToday.html here's the code right now im using: <script type="text/javascript" charset="utf-8"> jQuery(function() { jQuery('#multimonth').datePickerMultiMonth({ numMonths: 12, inline: true, selectMultiple: true, startDate: '01/09/2009', // DD/MM/YY month: 8, // 0=JAN 1=FEB ... year: 2009 }).bind( 'dpMonthChanged', function(event, displayedMonth, displayedYear) { //uncomment if you have firebug and want to confirm this works as expected... //console.log('dpMonthChanged', arguments); }).bind( 'dateSelected', function(event, date, jQuerytd, status) { //uncomment if you have firebug and want to confirm this works as expected... //console.log('dateSelected', arguments); }).val( new Date().asString()).trigger('change'); jQuery('#getSelected').bind( 'click', function(e) { alert(jQuery('#multimonth').dpmmGetSelected()); return false; }); }); </script> and this part is not being selected, I took it from the select todays date demo .val(new Date().asString()).trigger('change');

  • Forwarding first responder to UIScrollView unsuccessful

    - by Winston
    Hello, I am trying to create an image cropping bpx whereby the underlying image can be zoomed an scrolled while the cropping "maskview" layer stays the same and the corners can be dragged in any direction. To achieve this, the ImageView is added to a UIScrollView, and this is added to the SelectionViewController.view . I then add the cropping "maskview" layer to the SelectionViewController.view. I did this instead of adding to the scrollview so that the cropping maskview won't be expanded when the underlying image expands. @interface SelectionViewController : UIViewController <UIScrollViewDelegate> { UIImageView *photoview; // Added to self.scrollview MaskedView *maskedview; // Added to self.view UIScrollView *scrollview; // Added to self.view } The maskview has first responder status and responds accordingly. However, the only event I am interested in the maskview is if any of the corners are dragged (this works fine). The problem I want to try to solve is two-fold: If it is a pinch or zoom gesture, I am trying to forward the responder to the UIScrollview using: [self.nextResponder touchesMoved:touches withEvent:event]; The scrollview does not seem to respond. I have confirmed that the self.nextResponder after the maskedview is the SelectionViewController's view itself. From there, it doesn't seem like the UIScrollview responds. It does respond fine if I remove the cropping maskedview. If I zoom in on the underlying image and the cropping maskview rectangle is still the same, I want to now crop the actual zoomed image. Let's say for the upper left hand corner of the crop box, how can I find what the coordinates translates to in the underlying UIImageView now that the image has been zoomed? Any insight into either of these questions would be appreciated. Thank you, Winston

  • How to find the leaky faucet that loads into Malloc 32kb

    - by Rob
    I have been messing around with Leaks trying to find which function is not being deallocated (I am still new to this) and could really use some experienced insight. I have this bit of code that seems to be the culprit. Every time I press the button that calls this code, 32kb of memory is additionally allocated to memory and when the button is released that memory does not get deallocated. What I found was that everytime that AVAudioPlayer is called to play an m4a file, the final function to parse the m4a file is MP4BoxParser::Initialize() and this in turn allocates 32kb of memory through Cached_DataSource::ReadBytes My question is, how do I go about deallocating that after it is finished so that it doesn't keep allocating 32kb every time the button is pressed? Any help you could provide is greatly appreciated! - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { //stop playing theAudio.stop; // cancel any pending handleSingleTap messages [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(handleSingleTap) object:nil]; UITouch* touch = [[event allTouches] anyObject]; NSString* filename = [g_AppsList objectAtIndex: [touch view].tag]; NSString *path = [[NSBundle mainBundle] pathForResource: filename ofType:@"m4a"]; theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio prepareToPlay]; [theAudio setNumberOfLoops:-1]; [theAudio setVolume: g_Volume]; [theAudio play]; }

  • Drawing to the canvas

    - by Mattl
    I'm writing an android application that draws directly to the canvas on the onDraw event of a View. I'm drawing something that involves drawing each pixel individually, for this I use something like: for (int x = 0; x < xMax; x++) { for (int y = 0; y < yMax; y++){ MyColour = CalculateMyPoint(x, y); canvas.drawPoint(x, y, MyColour); } } The problem here is that this takes a long time to paint as the CalculateMyPoint routine is quite an expensive method. Is there a more efficient way of painting to the canvas, for example should I draw to a bitmap and then paint the whole bitmap to the canvas on the onDraw event? Or maybe evaluate my colours and fill in an array that the onDraw method can use to paint the canvas? Users of my application will be able to change parameters that affect the drawing on the canvas. This is incredibly slow at the moment.

  • Javascript onunload form submit isn't submitting data

    - by Kevin
    I currently have form that checks if a user has unsubmitted changes when they leave the page with a function called through the onunload event. Here's the function: function saveOnExit() { var answer = confirm("You are about to leave the page. All unsaved work will be lost. Would you like to save now?"); if (answer) { document.main_form.submit(); } } And here's the form: <body onunload="saveOnExit()"> <form name="main_form" id="main_form" method="post" action="submit.php" onsubmit="saveScroll()"> <textarea name="comments"></textarea> <input type="submit" name="submit2" value="Submit!"/> </form> I'm not sure what I'm doing wrong here. The data gets submitted and saved in my database if I just press the submit button for the form. However, trying to submit the form through the onunload event doesn't result in anything being stored, from what I can tell. I've tried adding onclick alerts to the submitt button and onsubmit alerts to the form elements and I can verify that the submit button is being triggered and that the form does get submitted. However, nothing gets passed stored in the database. Any ideas as to what I'm doing wrong? Thanks.

  • Intent.putExtras not consistent

    - by martinjd
    I have a weird situation with AlarmManager. I am scheduling an event with AlarmManager and passing in a string using intent.putExtra. The string is either silent or vibrate and when the receiver fires the phone should either turn of the ringer or set the phone to vibrate. The log statement correctly outputs the expected value each time. Intent intent; if (eventType.equals("start")) { intent = new Intent(context, SReceiver.class); } else { intent = new Intent(context, EReceiver.class); } intent.setAction(eventType+Long.toString(newId)); Log.v("EditQT",ringerModeType.toUpperCase()); intent.putExtra("ringerModeType", ringerModeType.toUpperCase()); PendingIntent appIntent = PendingIntent.getBroadcast(context, 0, intent, 0); AlarmManager alarmManager = (AlarmManager) getSystemService (Context.ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), appIntent); The receiver that fires when the alarm executes also has a log statement and I can see the first time around that the statement outputs the expected string either SILENT or VIBRATE. The alarm executes and then I change the value for putExtra to opposite string and the receiver still displays the previous value event though the call from the code above shows that the new value was passed in. The value for setAction is the same each time. audioManager = (AudioManager) context.getSystemService(Activity.AUDIO_SERVICE); Log.v("Start",intent.getExtras().get("ringerModeType").toString()); if (intent.getExtras().get("ringerModeType").equals("SILENTMODE")) { audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT); } else { audioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE); } Any thoughts?

  • IE8 (compatibility mode) won't load my Ajax content

    - by Jens Roland
    Hi all - I am working on a jQuery script on http://www.qxl.dk/ and I can't seem to get IE7 (or more accurately, IE8 in IE7 compatibility mode) to load my content. The sidebar box on the right named "QXL Aktuelt" loads its HTML content from an external file using Ajax load(), then triggers a custom jQuery event ("aktuelt_loaded") that starts a carousel script (like a scrolling newsticker). Several other content sections on the same page are loaded through Ajax and they work just fine, so I'm wondering what's going wrong. Everything works as expected in Firefox 3.6 and IE8, but not in IE8's compatibility mode. The script that loads the Ajax content is (inline on the page): <div id="qxlaktueltHolder"></div> <script type="text/javascript"> $("#qxlaktueltHolder").load("/contents/dk/modul/qxlaktuelt/qxlaktuelt.htm", function() { $("#qxlaktueltHolder").trigger("qxlaktuelt_loaded", []); }); </script> <script type='text/javascript' src='http://www.qxl.dk/contents/dk/js/jcarousellite_1.0.1.min.js'></script> <script type='text/javascript' src='http://www.qxl.dk/contents/dk/js/qxlaktuelt_liveload.js'></script> The external script that responds to the event is in the following file: http://www.qxl.dk/contents/dk/js/qxlaktuelt_liveload.js All ideas are very welcome.

  • Is there a way to get an ASMX Web Service created in VS 2005 to receive and return JSON?

    - by Ben McCormack
    I'm using .NET 2.0 and Visual Studio 2005 to try to create a web service that can be consumed both as SOAP/XML and JSON. I read Dave Ward's Answer to the question How to return JSON from a 2.0 asmx web service (in addition to reading other articles at Encosia.com), but I can't figure out how I need to set up the code of my asmx file in order to work with JSON using jQuery. Two Questions: How do I enable JSON in my .NET 2.0 ASMX file? What's a simple jQuery call that could consume the service using JSON? Also, I notice that since I'm using .NET 2.0, I i'm not able to implement using System.Web.Script.Services.ScriptService. Here's my C# code for the demo ASMX service: using System; using System.Web; using System.Collections; using System.Web.Services; using System.Web.Services.Protocols; /// <summary> /// Summary description for StockQuote /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class StockQuote : System.Web.Services.WebService { public StockQuote () { //Uncomment the following line if using designed components //InitializeComponent(); } [WebMethod] public decimal GetStockQuote(string ticker) { //perform database lookup here return 8; } [WebMethod] public string HelloWorld() { return "Hello World"; } } Here's a snippet of jQuery I found on the internet and tried to modify: $(document).ready(function(){ $("#btnSubmit").click(function(event){ $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "http://bmccorm-xp/WebServices/HelloWorld.asmx", data: "", dataType: "json" }) event.preventDefault(); }); });

  • jquery slide to attribute with specific data attribute value

    - by Alex M
    Ok, so I have the following nav with absolute urls: <ul class="nav navbar-nav" id="main-menu"> <li class="first active"><a href="http://example.com/" title="Home">Home</a></li> <li><a href="http://example.com/about.html" title="About">About</a></li> <li><a href="http://example.com/portfolio.html" title="Portfolio">Portfolio</a></li> <li class="last"><a href="example.com/contact.html" title="Contact">Contact</a></li> </ul> and then articles with the following data attributes: <article class="row page" id="about" data-url="http://example.com/about.html"> <div class="one"> </div> <div class="two" </div> </article> and when you click the link in the menu I would like to ignore the fact it is a hyperlink and slide to the current article based on its attribute data-url. I started with what I think is the obvious: $('#main-menu li a').on('click', function(event) { event.preventDefault(); var pageUrl = $(this).attr('href'); )}; and have tried find and animate but then I don't know how to reference the article with data-url="http://example.com/about.html". Any help would be most appreciated. Thanks

  • Objects in JavaScript defined and undefined at the same time (in a FireFox extension)

    - by Alexey Romanov
    I am chasing down a bug in a FireFox extension. I've finally managed to see it for myself (I've only had reports before) and I can't understand how what I saw is possible. One error message from my extension in the Error Console is "gBrowser is not defined". This by itself would be surprising enough, since the overlay is over browser.xul and navigator.xul, and I expect gBrowser to be available from both. Even worse is the actual place where it happens: line 101 of nextplease.js. That is, inside the function isTopLevelDocument, which is only called from onContentLoaded, which is only called from onLoad here: gBrowser.addEventListener(this.loadType, function (event) { nextplease.loadListener.onContentLoaded(event); }, true); So gBrowser is defined in onLoad, but somehow undefined in isTopLevelDocument. When I tried to actually use the extension, I got another error: "nextplease is not defined". The interesting thing is that it happened on lines 853 and 857. That is, inside the functions nextplease.getNextLink = function () { nextplease.getLink(window.content, nextplease.NextPhrasesMap, nextplease.NextImagesMap, nextplease.isNextRegExp, nextplease.NEXT_SEARCH_TYPE); } nextplease.getPrevLink = function () { nextplease.getLink(window.content, nextplease.PrevPhrasesMap, nextplease.PrevImagesMap, nextplease.isPrevRegExp, nextplease.PREV_SEARCH_TYPE); } So nextplease is somehow defined enough to call these functions, but isn't defined inside them. Finally, executing typeof(nextplease) in Execute JS returns "object". Same for gBrowser. How can this happen? Any ideas?

  • A better python property decorator

    - by leChuck
    I've inherited some python code that contains a rather cryptic decorator. This decorator sets properties in classes all over the project. The problem is that this I have traced my debugging problems to this decorator. Seems it "fubars" all debuggers I've tried and trying to speed up the code with psyco breaks everthing. (Seems psyco and this decorator dont play nice). I think it would be best to change it. def Property(function): """Allow readable properties""" keys = 'fget', 'fset', 'fdel' func_locals = {'doc':function.__doc__} def probeFunc(frame, event, arg): if event == 'return': locals = frame.f_locals func_locals.update(dict((k,locals.get(k)) for k in keys)) sys.settrace(None) return probeFunc sys.settrace(probeFunc) function() return property(**func_locals) Used like so: class A(object): @Property def prop(): def fget(self): return self.__prop def fset(self, value): self.__prop = value ... ect The errors I get say the problems are because of sys.settrace. (Perhaps this is abuse of settrace ?) My question: Is the same decorator achievable without sys.settrace. If not I'm in for some heavy rewrites.

  • wave.getState() returns null

    - by RMorrisey
    When trying to call wave.getState() in my Google Wave gadget, I get back null (no state object). How can I initialize the Wave state object? I am working in the Wave Sandbox. My ModulePrefs contains the following: <Require feature="wave" /> <Require feature="rpc"/> I got the "rpc" feature from some google groups post when searching for a fix, but it doesn't seem to be any help. The gadget contains a jQuery plugin, which defines the classes I use (not shown), attaches an event handler to the link that shows up in edit mode, and sets up the callback methods with the google wave gadget initializer: $.fn.extend({ $.gork.InitPass.newButtonClick = function newButtonClick() { var jer = new $.gork.InitPass.Player('Jeremias', 12, 2); var delta = {}; delta[jer.name] = jer.serialize(); wave.getState().submitDelta(delta); }; $.gork.InitPass.modeCallback = function modeCallback() { var state = wave.getState(); var mode = wave.getMode(); $.gork.InitPass.getContainer().ipCombatState(state, (mode == wave.Mode.EDIT)); }; $.gork.InitPass.stateCallback = function stateCallback() { $.gork.InitPass.getContainer().ipCombatState( wave.getState(), (wave.getMode() == wave.Mode.EDIT)); alert('state'); }; $.gork.InitPass.init = function init() { if (wave && wave.isInWaveContainer()) { var mode = wave.getMode(); $('.gork-ip-container').ipCombatState(null, (mode == wave.Mode.EDIT)); wave.setModeCallback($.gork.InitPass.modeCallback); wave.setStateCallback($.gork.InitPass.stateCallback); } }; })(jQuery); gadgets.util.registerOnLoadHandler($.gork.InitPass.init); $(function ready() { $.gork.InitPass.getContainer().find('.gork-ip-edit .addSection a.newButton').click( $.gork.InitPass.newButtonClick); }); So there are two main pieces of functionality here: When the mode changes, ipCombatState(...) is called. This changes the visual appearance of the gadget when the user puts the gadget in Edit mode (CTRL+E), by hiding the view DIV and displaying the edit DIV. The newButtonClick callback (which is attached to the link "a.newButton" in the edit container) is supposed to add Jeremias (Nate's Shadowrun character) to the gadget state, so that he'll be appear as a table row in edit mode. I have verified that the initializer method is called, and the view/edit mode switch works just fine (except the state is null). When I click on the new button link (the link at the bottom in edit mode), and trigger the newButtonClick handler, I get an error because wave.getState() also returns null. How can I initialize the wave state so that I can work with it? The purpose of my gadget will be to keep track of combat initiative order in a Shadowrun tabletop game (4th Ed). You can test it out in Wave and see what I have so far: http://gorkwobble.herobo.com/wave/init-pass.xml The actual javascript code is externalized to: http://gorkwobble.herobo.com/wave/init-pass.js P.S. If any Shadowrun players read this, and want to hear about it when I get the gadget working, leave a comment and I'll wave you.

  • Run AppleScript with Elevated Privileges from Objective C

    - by cygnl7
    I'm attempting to execute an uninstaller (written in AppleScript) through AuthorizationExecuteWithPrivileges. I'm setting up my rights after creating an empty auth ref like so: char *tool = "/usr/bin/osascript"; AuthorizationItem items = {kAuthorizationRightExecute, strlen(tool), tool, 0}; AuthorizationRights rights = {sizeof(items)/sizeof(AuthorizationItem), &items}; AuthorizationFlags flags = kAuthorizationFlagDefaults | kAuthorizationFlagExtendRights | kAuthorizationFlagPreAuthorize | kAuthorizationFlagInteractionAllowed; status = AuthorizationCopyRights(authorizationRef, &rights, NULL, flags, NULL); Later I call: status = AuthorizationExecuteWithPrivileges(authorizationRef, tool, kAuthorizationFlagDefaults, (char *const *)args, NULL); On Snow Leopard this works fine, but on Leopard I get the following in syslog.log: Apr 19 15:30:09 hostname /usr/bin/osascript[39226]: OpenScripting.framework - 'gdut' event blocked in process with mixed credentials (issetugid=0 uid=501 euid=0 gid=20 egid=20) Apr 19 15:30:12: --- last message repeated 1 time --- ... Apr 19 15:30:12 hostname [0x0-0x2e92e9].com.example.uninstaller[39219]: /var/folders/vm/vmkIi0nYG8mHMrllaXaTgk+++TI/-Tmp-/TestApp_tmpfiles/Uninstall.scpt: Apr 19 15:30:12 hostname [0x0-0x2e92e9].com.example.uninstaller[39219]: execution error: «constant afdmasup» doesn’t understand the «event earsffdr» message. (-1708) After researching this for a few hours my first guess is that Leopard somehow doesn't want to do what I'm doing because it knows it's in a setuid situation and blocks calls that ask about user-specific things in the applescript. Am I going about this all wrong? I just want to run the equivalent of "sudo /usr/bin/osascript ..." Edit: FWIW, the first line that causes the "execution error" is: set userAppSupportPath to (POSIX path of (path to application support folder from user domain)) However, even with an empty script (on run argv, end run and that's it) I still get the 'gdut' message.

  • Why do SNMP agents need MIB files?

    - by user1495181
    After reading up on SNMP and some of the questions help here I think understand the agent role as a SNMP service to device (Like SQL, it is an API to storage). When you execute a SQL query the SQL engine does all the work and returns the result - You don't need to be aware of how the storage and where the storage is done. But MIBs are not actual storage , so what is the role of my agent? if the agent only register the MIB like i follow in this tutorial, is it not used as handler at all? Say that I want monitor my application's pending request queue, so I want an agent that all SNMP request for application_pending_request will be fired for it and it will return the queue depth. Why do I need to have an actual MIB when all I need to poll my application queue in order to get result?

  • Objecive C Error, Message sent to deallocated object

    - by Dave C
    Hello, I have several buttons on my app that are being created dynamically. They are all pointed at the button click event when pressed. When the button pressed method is called, the sender's tag(int value) is parsed into the controllers house ID. It works with one of the buttons... the first one created to be specific, but the others throw the following error: -[CFNumber intValue]: message sent to deallocated instance 0xc4bb0ff0 I am not releasing these buttons anywhere in my code... I haven't set them to auto release or anything like that... just wondering why they are doing this on the click. The button click event: - (IBAction) ButtonClick: (id) sender { HouseholdViewController *controller = [[HouseholdViewController alloc] initWithNibName:@"HouseholdViewController" bundle:nil]; controller.delegate = self; controller.HouseID = [(NSInteger)[(UIButton *)sender tag] intValue]; //this line throws an error controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Where I am creating the buttons: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(MyLongInScreenCoords, MyLatInScreenCoords, 50, 50); UIImage *buttonImageNormal = [UIImage imageNamed:@"blue_pin.png"]; UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:50 topCapHeight:50]; [button setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal]; [self.view addSubview:button]; button.tag = [NSNumber numberWithInt:[[words objectAtIndex: i] intValue]]; ButtonPoints[CurrentHouseCount][0] = button; ButtonPoints[CurrentHouseCount][1] = [NSValue valueWithCGPoint:CGPointMake(MyActualLat, MyActualLong)]; [button addTarget:self action:@selector(ButtonClick:) forControlEvents:UIControlEventTouchUpInside]; CurrentHouseCount++; Thank you for any assistance.

  • SignalR - Handling disconnected users

    - by guilhermeGeek
    Hy, I'm using the signalR library on a project to handle an notification and chat modules. I've a table on an database to keep a track of online users. The HUB for chat is inheriting IDisconnect where i disconnect the user. After disconnecting the user, i warm the users about that event. At this point, i check if the disconnect user is the client. If it's, then i call an method on HUB to reconnect the user (just update the table). I do this because with the current implementation, once the user closes a tab on the browser it calls the Disconnect task but he could have another tab opened. I've not tested (with larger requests) this module yet, but on my development server it could take a few seconds between the IDisconnect event, and the request from the user to connect again. I'm concerned with my implementation to handle disconnected users from the chat but i can't see another way to improve this. If possible, could someone give me a advice on this, or this is the only solution that i've?

  • How can I load a view based on how long I hold a UIButton?

    - by Thomas
    Hello all, I've searched the net and documentation, but haven't found anything quite like what I'm trying to do. I'm working on an app where I want to load one view if a UIButton is held for x seconds, another if it's held for x+y seconds, etc. I found this tutorial. The problem I'm running into is, how do I switch the length of the button press? The tutorial switched the number of taps. -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSSet *allTouches = [event allTouches]; switch ([allTouches count]) { case 1: // Single touch { // Get the first touch. UITouch *touch = [[allTouches allObjects] objectAtIndex:0]; switch ([touch tapCount]) { case 1: // Single Tap. { // Start a timer timer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(showAlertView:) userInfo:nil repeats:NO]; [timer retain]; } break; case 2: // Double tap. break; } } break; case 2: // Double touch { } break; default: break; } } Any suggestions? Thanks! Thomas

  • Application log aggregation, management and notifications...

    - by Matthew Savage
    I'm wondering what everyone is using for logging, log management and log aggregation on their systems. I am working in a company which uses .NET for all it's applications and all systems are Windows based. Currently each application looks after its own logging and notifications of failures (e.g. if app A fails it will send out its own 'call for help' to an admin). While this current practice works its a bit hacky and hard to manage. I've been trying to find some options for making this work better and I've come up with the following: log4net & Chainsaw (ah, if it works). Logging via log4net or another framework into a central database & rolling our own management tool. Logging to the Windows event log and using MOM or System Center Operations Manager to aggregate and manage each of these servers & their apps. A hand-rolled solution to suck all the log files into one point and work some magic across them. Essentially what we are after is something which can pull log entries all together and allow for some analytics to be run across them, plus use a kind of event based system to, for example, send out a warning email when there have been 30+ warning level logs for an application in the last x minutes. So is there anything I've missed, or something someone else can suggest?

  • file upload working in one and not the other help

    - by rod
    Hi All, I have a web application which has 2 different versions deployed. 1 is a ASP.Net web forms version and the other is an ASP.Net MVC version I have a File Upload page which dynamically creates a directory folder for the target location of the file to be uploaded to. The application is using Forms Authentication for outside users and Integrated Windows Authentication for inside the network users. I have an issue where a user can upload a file in the ASP.Net Web Forms version fine. But when the same user tries to upload the file in the MVC version the user gets a File.IO permission error. Here's a kicker: I can upload the same file in both versions. The user is in a remote location but I believe they're still inside the network because they can work on the other parts of the application just fine. Possible clues: In the event log there's an info that says Event code:4005 Forms authentication failed for the request. Reason: Ticket supplied was invalid. What would be your initial thoughts on why this is happening? Thanks, Rod.

  • jQuery Autocomplete & jTemplates - handling response

    - by Diegos Grace
    Has anyone had any experience with using jTemplates to display autocomplete results. I have the following $("#address-search").autocomplete({ source: "/Address/SearchAddress", minLength: 2, delay: 400, focus: function (event, ui) { $('#address-search').val(ui.item.name); return false; }, parse: function(data) { $("#autocomplete-results").setTemplate($("#templateHolder").html()); $("#autocomplete-results").processTemplate(data); }, select: function (event, ui) { $('#address-search').val(ui.item.name); $('#search-address-id').val(ui.item.id); $('#search-description').html(ui.item.address); }); and the simple jtemplate holder: <script type="text/html" id="templateHolder"> <ul class="autocomplete"> {#foreach $T as data} <li>{$T.name}</li> {#/for} </ul> </script> Above i'm using 'Parse' to format results, I've also tried the autocomplete result method but not having any luck so far. The only success I've had is by using the private method ._renderItem and formatting the data that way but we want to render the output using the jTemplate. Any advice appreciated.

  • Opengl Iphone SDK: How to tell if you're touching an object on screen?

    - by TheGambler
    First is my touchesBegan function and then the struct that stores the values for my object. I have an array of these objects and I'm trying to figure out when I touch the screen if I'm touching an object on the screen. I don't know if I need to do this by iterating through all my objects and figure out if I'm touching an object that way or maybe there is an easier more efficient way. How is this usually handled? -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ [super touchesEnded:touches withEvent:event]; UITouch* touch = ([touches count] == 1 ? [touches anyObject] : nil); CGRect bounds = [self bounds]; CGPoint location = [touch locationInView:self]; location.y = bounds.size.height - location.y; float xTouched = location.x/20 - 8 + ((int)location.x % 20)/20; float yTouched = location.y/20 - 12 + ((int)location.y % 20)/20; } typedef struct object_tag // Create A Structure Called Object { int tex; // Integer Used To Select Our Texture float x; // X Position float y; // Y Position float z; // Z Position float yi; // Y Increase Speed (Fall Speed) float spinz; // Z Axis Spin float spinzi; // Z Axis Spin Speed float flap; // Flapping Triangles :) float fi; // Flap Direction (Increase Value) } object;
