  • Iterating through Event Log Entry Collection, IndexOutOutOfBoundsException

    - by fjdumont
    Hello, in a service application I am iterating through the Windows application event log to parse Events in order react depanding on the entry message. In the case that the event log is full (Windows usually makes sure there is enough space by deleting old entries - this is configurable in the eventvwr.exe settings), the service always runs into an IndexOutOfBoundsException while iterating through the EventLog.Entries collection. No matter how I iterate (for-loop, using the collections enumerator, copying the collection into an array, ...), I can't seem to get rid of this ´bug´. Currently, I ensure that the log is not full in order to keep the service running by regularly deleting the last few item by parsing the event log file and deleting the last few nodes (Don't beat me up, I couldn't find a better alternative...). How can I iterate through the collection without trying to access already deleted entries? Is there probably a more elegant method? I am only trying to acces the logs written during the last x seconds (even LINQ failed to select those when the log is full - same exception), could this help? Thanks for any advice and hints Frank Edit: I forgot to mention that my assumption is the loops are accessing entries which are being deleted during iteration by Windows. Basically that is why I tried to clone the collection. Is there perhaps a way to lock the collection for a small amount of time for just my application?

  • Fade out/in sperate divs with button click

    - by user1914298
    I saw a flash website and was curious to now if this is something possible to build using Jquery, obviously not the entire thing. I was more looking to fade out div1 and div2 with a button click. This is the example site: www.justinfarrellyconstruction.com Example: If i come to the homepage and click the portfolio button the Gallery Div will fade out then fade in another image. At the same time the Text div will fade out its content and load the portfolio text. My apologies if this does not make sense, this is all quite new to me and im trying got learn.

  • Javascript: click and dblclick deliver different parentNodes on same html. Why?

    - by user1658206
    currently I work on an very small wysiwyg editor based on jquery. I dont care about IE oder Chrome, just Firefox. My problem is to find if the selection is in a link for to get the value of the href attribute if is set. With click the node of the link is found, with double click always the body. It is in designMode. My event-handler for click and dblclick. The vars current_selection, current_node, iframe and container are global. selection_handler:function() { current_selection = iframe.getSelection(); current_node = current_selection.anchorNode; if(current_node.nodeName == "#text") { current_node = current_node.parentNode; } $('#log').text(current_node.nodeName); }, The log shows mit for example 'body', when I click in unformated text. When I add a link with execCommand('createLink',...) the log shows 'A'. That works. When I mark the linked word with 2 click from start to end, the log shows 'A'. But with double click I always get 'body'. So I can't get the href attribute. The handler is defined in the init: init:function(options) { ... iframe = $('#wysiwyg-'+container.attr('id'))[0].contentWindow; iframe.addEventListener('dblclick',methods.selection_handler,false); iframe.addEventListener('click',methods.selection_handler,false); ... } Has somebody an idea what is wrong?

  • .click() callback references local variable from the calling method instead of copying by value

    - by Eric Freese
    The following jQuery Javascript code is included on an otherwise empty page. $(function() { for (var i = 0; i < 10; i++) { element = $('<div>' + i + '</div>'); element.click(function() { alert(i); }); $('body').append(element); } }); The desired behavior is that this code should generate 10 div elements numbered from 0 to 9. When you click on a div element, an alert popup will show the number of the div element you clicked on (i.e. if a user clicks on the div element labeled '4', the alert popup should show the number 4). The alert popup instead shows the number 10 regardless of which div element is clicked on. How can I modify this code to make it behave in the desired way?

  • jQuery hover() event on div element within a button element

    - by jakeisonline
    I can't seem to get jQuery to notice the div within the following markup <button class="button submit positive right" id="omnisubmit" type="submit"> <div class="label">Submit</div> <div class="controller">&nbsp;</div> </button> And here is the jQuery I'm currently using: $("button#omnisubmit div.controller").hover(function () { console.log("Hover..."); }); However, jQuery doesn't seem to pick up when the mouse is hovering over that div, $("button#omnisubmit div.controller").hover( works correctly, of course. I have a feeling it's because putting divs inside buttons may not be standard HTML?

  • Event Dispatching, void pointer and alternatives

    - by PeeS
    i have my event dispatching / handling functionality working fine, but there is one issue that i need to resolve. Long story short, here are the details. // The event structure struct tEventMessage { // Type of the event int Type; // (void*) Allows those to be casted into per-Type objects void *pArgument1; void *pArgument2; }; I am sending events from different modules in my engine by using the above structure, which requires a pointer to an argument. All messages are queued, and then dispatched on the next ::Tick(). It works fine, untill i try to send something that doesn't exist in next ::Tick, for example: When a mouse click is being handled, it calculates the click coordinates in world space. This is being sent with a pointer to a vector representing that position, but after my program quits that method, this pointer gets invalid obviously, cause local CVector3 is destructed: CVector2 vScreenSpacePosition = vAt; CVector3 v3DPositionA = CVector3(0,0,0); CVector3 v3DPositionB = CVector3(0,0,0); // Screen space to World space calculation for depth zNear v3DPositionA = CMath::UnProject(vScreenSpacePosition, m_vScreenSize, m_Level.GetCurrentCamera()->getViewMatrix(), m_Level.GetCurrentCamera()->getProjectionMatrix(), -1.0 ); // Screen space to World space calculation for depth zFar v3DPositionB = CMath::UnProject(vScreenSpacePosition, m_vScreenSize, m_Level.GetCurrentCamera()->getViewMatrix(), m_Level.GetCurrentCamera()->getProjectionMatrix(), 1.0); // Send zFar position and ScreenSpace position to the handlers // Obviously both vectors won't be valid after this method quits.. CEventDispatcher::Get()->SendEvent(CIEventHandler::EVENT_SYSTEM_FINGER_DOWN, static_cast<void*>(&v3DPositionB), static_cast<void*>(&vScreenSpacePosition)); What i want to ask is, if there is any chance i could make my tEventMessage more 'template', so i can handle sending objects like in the above situation + use what is already implemented? Can't figure it out at the moment.. What else can be done here to allow me to pass some locally available data ? Please can somebody shed a bit of light on this please?

  • INotifyPropertyChanged event listener within respective class not firing on client side (silverlight)

    - by Rob
    I'm trying to work out if there's a simple way to internalize the handling of a property change event on a Custom Entity as I need to perform some bubbling of the changes to a child collection within the class when the Background Property is changed via a XAML binding: public class MyClass : INotifyPropertyChanged { [Key] public int MyClassId { get; set; } [DataMember] public ObservableCollection<ChildMyClass> MyChildren { get; set; } public string _backgroundColor; [DataMember] public string BackgroundColor { get { return this._backgroundColor; } set { this._backgroundColor = value; if (this.PropertyChanged != null) { this.PropertyChanged(this, new PropertyChangedEventArgs("BackgroundColor")); } } } public MyClass() { this.BackgroundColor = "#FFFFFFFF"; this.PropertyChanged += MyClass_PropertyChanged; } public event PropertyChangedEventHandler PropertyChanged; void MyClass_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e) { //Do something here - fires client side but not server side } } I can listen to the event by externalizing it without any problems but it's an ugly way to handle something that want to set and forget inside my class e.g.: public class SomeOtherClass { public SomeOtherClass() { MyClass mc = new MyClass(); mc.PropertyChanged += MyClass_PropertyChanged; } void MyClass_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e) { MyClass mc = (MyClass)sender; mc.UpdateChildren(); } }

  • In jquery Set a delay to fade out or fadeout right away on click

    - by JClu
    I am trying to right a script for a notification popup. I wan't the popup to fade out after X seconds or fadeout when the user clicks on the message. I can get both effects to work individually but when I try to combine them fadeOut works. This is my code so far: function notify(data, type) { switch(type) { case "success": $('#notify').html(data) .removeAttr("style") .addClass('notifySuccess') .click(function() { $("#notify").fadeOut(); }) .delay(5000).fadeOut(); break; case "error": $('#notify').html(data) .removeAttr("style") .addClass('notifyFailure') .click(function() { $("#notify").fadeOut(); }) .delay(5000).fadeOut(); break; } }

  • Preventing click event with jQuery drag and drop

    - by Sasha Yanovets
    I have an elements on page that are draggabe with jQuery. These elements have click event wich navigates to another page (ordinary links for example). What is the best way to prevent click from firing on dropping such element, while allowing clicking it in not drag and drop state? I have this problem with sortable elements, but think it is good to have solution for general drag and drop. I've solved the problem for myself. After that found that same solution exists for Scriptaculous, but maybe someone have a better way to achieve that.

  • initialize jquery slider with hidden input value from database.

    - by ludwigs3rd
    I'm using a slider as user input for a screen. Basically it's a bulk update screen where there is a table with multiple rows, thus multiple sliders. I created it so that the hidden value is what gets posted in the form. <td> <input class="percentageProvidedHidden" type="hidden" name='<%= "Values[" + i + "].Percentage" %>' value='<%=item.Percentage %>' /> <div class="percentageProvidedSlider"></div> </td> I have the update working just fine (move slider changes hidden input value, submit, values are updated in db), however, I can't get the damn thing to initialize with the value of the hidden input (note the "value: " parameter below). In this case I think $(this) isn't actually $('percentageProvidedSlider') but the page itself. Can someone help me get the slider value to initialize with the hidden input field? I'm using ASP .Net MVC 2 so if there are any methods I should try with that I welcome them as well. $('.percentageProvidedSlider').slider( { min: 0, max: 100, step: 25, value: $(this).parents('tr').find('input.percentageProvidedHidden').val(), slide: function(e, ui) { var mypos = ui.value; $(this).find('.ui-slider-handle').text(ui.value); }, change: function(event, ui) { var myVal = $(this).slider("option", "value"); $(this).parents('tr').find('input.percentageProvidedHidden').val(myVal); var myDropDown = $(this).parents('tr').find('select.verified'); } });

  • JQuery - Slide Example

    - by gav
    Hi All, I want to perform a simple slide motion on an HTML element. JQuery is already available on the site in question so the next logical step for me was to look at their documentation. JQuery - Slide down When I check out their demo however, it doesn't seem to be functioning. In firebug they have an error; missing ) after argument list wyciwyg://0/http://docs.jquery.com/UI/Effects/Slide Line 18 Whilst the error seems simple, I can't work out how to correct it (On thier site by editing the JS). On my own site using the same example an error is found in the JQuery 1.4.2 script itself; jQuery.easing[specialEasing || defaultEasing] is not a function file:///home/gav/ee-workspaces/web/site/php/jquery-1.4.2.js Line 5854 I don't mean to sound lazy / rude but what's going on? Is the JQuery site and newest release actually broken, I doubt it, what am I doing wrong? I'm a CS grad with no real web dev experience so I'm not used to this method of debugging, where should I start with this? Thanks, Gav

  • Add autoFill capabilities to jQuery-UI 1.8.1

    here's what I currently have, unfortunately I cannot seem to figure out how to get autoFill to work with jQuery-UI... It used to work with the straight up Autocomplete.js <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js" type="text/javascript"></script> <script src="http://jquery-ui.googlecode.com/svn/tags/latest/external/jquery.bgiframe-2.1.1.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/i18n/jquery-ui-i18n.min.js" type="text/javascript"></script> <script language="javascript" type="text/javascript"> var thesource = "RegionsAutoComplete.axd?PID=3" $(function () { function log(message) { $("<div/>").text(message).prependTo("#log"); $("#log").attr("scrollTop", 0); } $.expr[':'].textEquals = function (a, i, m) { return $(a).text().match("^" + m[3] + "$"); }; $("#birds").autocomplete({ source: thesource, change: function (event, ui) { //if the value of the textbox does not match a suggestion, clear its value if ($(".ui-autocomplete li:textEquals('" + $(this).val() + "')").size() == 0) { $(this).val(''); } else { log(ui.item ?

Does anyone know how to extract the ID out of the autocomplete when you don't actually select the field?

  • using mod-rewrite to redirect requests for jquery.js to GoogleAPI cache

    - by Aditya Advani
    Hi All, Our Linux server with Apache 2.x, Plesk 8.x hosts a number of e-commerce websites. To take advantage of browser caching we would like to use Google's provided copy of jquery.js. Hence in the vhost.conf file of each we can use the following RewriteRule RewriteCond %{REQUEST_FILENAME} jquery.min.js [nc] RewriteRule . http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js [L] And in vhost_ssl.conf RewriteCond %{REQUEST_FILENAME} jquery.min.js [nc] RewriteRule . https://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js [L] OK now these rules work fine in the individual vhost.conf files of each domain. However we host over 200 domains, I would like for them to work but cannot seem to get them to work globally in the httpd.conf file. Challenges are the following: Get the rewriterule to work in httpd.conf Detect if HTTPS is on, and if it is and the is is a secure page, rewrite to ... Each individual domain will still have it's own custom mod-rewrite rules. Which rules take precedence - global or per-domain? Do they combine? Is it ok if I have the "RewriteEngine On" directive in the global httpd.conf and then again in the vhost.conf? Please let me know what your guys' suggestions are. Desperate for a solution to this problem.
