  • Deriving an HTMLElement Object from jQuery Object

    - by Jasconius
    I'm doing a fairly exhaustive series of DOM manipulations where a few elements (specifically form elements) have some events. I am dynamically creating (actually cloning from a source element) several boxes and assigning a change() event to them. The change event executes, and within the context of the event, "this" is the HTML Element Object. What I need to do at this point however is determine a contact for this HTML Element Object. I have these objects stored already as jQuery entities in assorted arrays, but obviously [HTMLElement Object] != [Object Object] And the trick is that I cannot cast $(this) and make a valid comparison since that would create a new object and the pointer would be different. So... I've been banging my head against this for a while. In the past I've been able to circumvent this problem by doing an innerHTML comparison, but in this case the objects I am comparing are 100% identical, just there's lots of them. Therefore I need a solid comparison. This would be easy if I could somehow derive the HTMLElement object from my originating jQuery object. Thoughts, other ideas? Help. :(

  • Padding is invalid and cannot be removed

    - by Ajay
    I have hosted an asp.net 2.0 site. Everyday, i am getting an error "Padding is invalid and cannot be removed" 2-3 times. Backend used is sql server 2005. the site is controlled via plesk 9.2 CP. Pooling is enabled with timeout as 120 Minutes, in IIS. Can it be the reason for this? I have not used any encryption except for the stored passwords(MD5) The error message is : " Base Exception = : Padding is invalid and cannot be removed. - Source : System.Web - TargetSite :Void ThrowError(System.Exception, System.String, System.String, Boolean)Message : Validation of viewstate MAC failed.

  • Symfony/Propel NestedSet left/right ID corruption/adjustment

    - by Mike Crowe
    Hi folks, I have a nested set application that seems to be getting corrupted. Here's what I'm seeing: We're using nested sets for a binary tree (any node can have 2 children). It appears to be working fine, but some event causes a discrepancy. For instance, when I do a getNumberOfDescendants() for the root node, it will slowly increase as this event happens. However, displaying the tree works fine, as does inserting (apparently). Has anybody seen anything like this before? For instance, my repair program shows this as the repairs that it makes: User pxxxxx left 0=>0, right 145=>129 User axxxxx left 1=>1, right 124=>106 User mxxxxx left 119=>117, right 120=>118 User fxxxxx left 125=>107, right 144=>128 User fxxxxx left 126=>108, right 131=>113 User rxxxxx left 127=>109, right 128=>110 User mxxxxx left 129=>111, right 130=>112 User mxxxxx left 132=>114, right 143=>127 User cxxxxx left 133=>115, right 142=>126 User gxxxxx left 134=>116, right 137=>121 User mxxxxx left 135=>119, right 136=>120 User jxxxxx left 138=>122, right 141=>125 User axxxxx left 139=>123, right 140=>124 I thought at first it was when I deleted a user, but it has since occurred w/o that event. Anybody know of a cause that might generate this? I've tested ad nauseum on my local machine, but I can't duplicate it. I do have an issue where my production box is PHP 5.2.0, whereas my test device is 5.2.10. Could that be an issue? TIA Mike

  • Flex: How to resize DisplayObject to fit panel in Flex application

    - by ohm
    I am trying to attach some of my actionscript class, inherited from Sprite, to my Flex application by attaching it to a UIComponent, then add UIComponent to a panel. However, the size of my Sprite class appears to be larger than the panel. So, I try to resize it using DisplayObject.scale property, but I need to know the size of my container. Since I try to make my code reusable, I figure that I should let my Sprite class handle the resize by getting it via its parent property (let's say, I can resize it by set this.scaleX = this.parent.Width/this.width or something like this) However, my Sprite class's parent, which is the UIComponent, has width/height of 0. So, my question is: 1) Is there any better way to resize DisplayObject class to fit its container when attached to Flex object? 2) If you know, why my UIComponent's size remain 0 and my DisplayObject still appears at its full size? Here's my code, using Flash Builder 4: private var loader:Loader = new Loader(); private function testLoader():void { var urlRequest:URLRequest = new URLRequest("http://localhost/welcome.png"); loader.load(urlRequest); loader.contentLoaderInfo.addEventListener(Event.COMPLETE,onLoaderLoadComplete); } private function onLoaderLoadComplete(e:Event):void { loader.contentLoaderInfo.removeEventListener(Event.COMPLETE,onLoaderLoadComplete); var ui : UIComponent = new UIComponent(); ui.addChild(loader); panelTest.addElement(ui); trace("ui.width = " + ui.width); trace("ui.height = " + ui.height); trace("loader.width = " + loader.width); trace("loader.height = " + loader.height); trace("panelTest.width = " + panelTest.width); trace("panelTest.height = " + panelTest.height); } And this is the result when run: ui.width = 0 ui.height = 0 loader.width = 571 loader.height = 411 panelTest.width = 480 panelTest.height = 320

  • TableView Cells unresponsive

    - by John Donovan
    I have a TableView and I wish to be able to press several cells one after the other and have messages appear. At the moment the cells are often unresponsive. I found some coed for a similar problem someone was kind enough to post, however, although he claimed it worked 100% it doesn't work for me. The app won't even build. Here's the code: -(UIView*) hitTest:(CGPoint)point withEvent:(UIEvent*)event { // check to see if the hit is in this table view if ([self pointInside:point withEvent:event]) { UITableViewCell* newCell = nil; // hit is in this table view, find out // which cell it is in (if any) for (UITableViewCell* aCell in self.visibleCells) { if ([aCell pointInside:[self convertPoint:point toView:aCell] withEvent:nil]) { newCell = aCell; break; } } // if it touched a different cell, tell the previous cell to resign // this gives it a chance to hide the keyboard or date picker or whatever if (newCell != activeCell) { [activeCell resignFirstResponder]; self.activeCell = newCell; // may be nil } } // return the super's hitTest result return [super hitTest:point withEvent:event]; } With this code I get this warning: that my viewController may not respond to pointsInside:withEvent (it's a TableViewController). I also get some faults: request for member 'visibleCells' in something not a structure or a union. incompatible type for argument 1 of pointInsideWithEvent, expression does not have a valid object type and similar. I must admit I'm not so good at reading other people's code but I was wondering whether the problems here are obvious and if so if anyone could give me a pointer it would be greatly appreciated.

  • GridView not DataBinding Automatically after ObjectDataSource Select Method

    - by John Polvora
    I've created a objectadasource that returns a datatable, the gridview is binded to this datasource. the ODS have parameters assigned on the Page_Load event, and the ODS returns the data ok and the gridview shows it fine. the problem is i have a textbox with a filter. first I created a filterexpression in gridview, using the contents of the textbox, worked fine for me. but now I've enabled the paging in gridview. then the filterexpression is not useful now, since the ODS returns only the rows of the pagesize of gridview. I did a new ODS method that select data from parameters page and pagesize according to GridView, and it's OK. now my filter textbox passes his text property to a parameter of the ods select method, then the ods gets the data based on my filter and shows it in the grid. on the Page_Load: ObjectDataSource_Lista.SelectParameters["search"].DefaultValue = filter; ObjectDataSource_Lista.SelectParameters["id"].DefaultValue = ID.ToString(); but when I change the value of the filter, the grid doesn't refresh. on debugging. I see that the ODS Select Method is refreshed ok, but the GridView don't. So I need to call mannually the Databind() method of the grid, to refresh data. the problem is, I have a commandbutton on the grid, and if I manually databind(), the command button stops functioning, generating Page ValidateRequest errors. My question is: how to databind() the grid automatically after the datasource refreshed? ps: on the ODS Selected event, causes a infinite loop and the debug webserver crashes. Temporary solution: Created a Variable private bool wasdatabound; on the event GridView_Databound, set wasdatabound = true; on the Page_PreRenderComplete, if ((GridView1.Visible) && (!databounded)) GridView1.DataBind();

  • WPF: How do I get a reference to a styled window control in code behind?

    - by Brad
    I have a window defined with a style: <Window x:Class="winBorderless" x:Name="winBorderless" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Local="clr-namespace:WindowStyle" Style="{StaticResource Window_Cartesia}" WindowStartupLocation="CenterScreen" BorderThickness="1" BorderBrush="#FF9CAAC1" Margin="5" Title="[Document Title]"> and the style defined in an application level dictionary: <Style x:Key="Window_Cartesia" TargetType="{x:Type Window}"> <Setter Property="WindowStyle" Value="None"/> <Setter Property="AllowsTransparency" Value="True"/> <Setter Property="Background" Value="Transparent"/> <EventSetter Event="Loaded" Handler="Loaded"/> <EventSetter Event="PreviewKeyDown" Handler="Preview_KeyDown"/> <EventSetter Event="MouseMove" Handler="FullScreen_MouseMove"/> <Setter Property="Template"> In code behind I have a reference to the Window instance set: Win = DirectCast(sender, winBorderless) This allows access to the window properties as the EventSetters pass references to the various controls. However, it doesn't provide for access to the controls defined in the style through the window reference as they don't exist there. So, what is the best way to reference a control through code behind that is defined in the style. I'd prefer not to iterate the trees to find them but ya gotta do....

  • HttpModule to Write Out JavaScript Script References to the Response

    - by Chris
    On my page in the Page_Load event I add a collection of strings to the Context object. I have an HttpModule that will fire EndRequest and retrieve the collection of strings. What I then do is write out a script reference tag (based on the collection of strings) to the response. The problem is that the page reads the script reference but doesn't retrieve the contents of the file (I imagine because this is occurring in the EndRequest event). I can't fire the BeginRequest event because I won't have access to the Context Items collection. I tried to also registering an HttpHandler which Processes the request of the script reference but I can't access the collection of strings in the Context.Items from there. Any suggestions? Page_Load: protected void Page_Load(object sender, EventArgs e) { Context.Items.Add("ScriptFile", "/UserControls.js"); } HttpModule: public void OnEndRequest(Object s, EventArgs e) { HttpApplication app = s as HttpApplication; object script = app.Context.Items["ScriptFile"]; app.Response.Write("<script type='text/javascript' src='" + script + "'></script>"); }

  • Retrieve position of a google maps v3 marker to Qt in a desktop app with QtWebKit

    - by nelas
    I'm building a Qt app with Python where you can point and click at a (google) map and get the coordinates of the location. The map is shown through a QWebView loading a simple HTML page and the user can create markers by clicking. Screenshot of the widget after clicking on the map: However, I'm having trouble to retrieve the just-clicked location coordinates back to Qt (so that I can use them as variables -- and, for example, show them in the QLineEdits on the topleft corner above, as current location of the marker). This is the relevant part of the HTML file: <script type="text/javascript"> var map; function initialize() { var local = new google.maps.LatLng(-23.4,-40.3); var myOptions = { zoom: 5, center: local, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); google.maps.event.addListener(map, 'rightclick', function(event) { placeMarker(event.latLng); }); } function placeMarker(location) { var clickedLocation = new google.maps.LatLng(location); var marker = new google.maps.Marker({ position: location, map: map }); map.setCenter(location); } function dummyTxt() { return 'This works.'; } </script> I've been trying with evaluateJavaScript, but was not able to retrieve the coordinates. I tried to created a function to access the position with marker.getPosition(), but with no luck. The dummy below works though.. newplace = QWebView.page().mainFrame().evaluateJavaScript(QString('dummyTxt()')) >>> print newplace.toString() This works. Any suggestions on how to get the coordinates back to Qt?

  • Capture *all* display-characters in JavaScript?

    - by Jean-Charles
    I was given an unusual request recently that I'm having the most difficult time addressing that involves capturing all display-characters when typed into a text box. The set up is as follows: I have a text box that has a maxlength of 10 characters. When the user attempts to type more than 10 characters, I need to notify the user that they're typing beyond the character count limit. The simplest solution would be to specify a maxlength of 11, test the length on every keyup, and truncate back down to 10 characters but this solution seems a bit kludgy. What I'd prefer to do is capture the character before keyup and, depending on whether or not it is a display-character, present the notification to the user and prevent the default action. A white-list would be challenging since we handle a lot of international data. I've played around with every combination of keydown, keypress, and keyup, reading event.keyCode, event.charCode, and event.which, but I can't find a single combination that works across all browsers. The best I could manage is the following that works properly in =IE6, Chrome5, FF3.6, but fails in Opera: NOTE: The following code utilizes jQuery. $(function(){ $('#textbox').keypress(function(e){ var $this = $(this); var key = ('undefined'==typeof e.which?e.keyCode:e.which); if ($this.val().length==($this.attr('maxlength')||10)) { switch(key){ case 13: //return case 9: //tab case 27: //escape case 8: //backspace case 0: //other non-alphanumeric break; default: alert('no - '+e.charCode+' - '+e.which+' - '+e.keyCode); return false; }; } }); }); I'll grant that what I'm doing is likely over-engineering the solution but now that I'm invested in it, I'd like to know of a solution. Thanks for your help!

  • viewstack causing error 1065 variable not defined issue?

    - by jason
    I've got an flex application where I have a left side TREE control and a viewstack on the right and when someone selects the tree it loads the named viewstack based on the hidden node value of the XML of the tree. But it's throwing a error 1065 variable not defined on a viewstack which worked on the last browser refresh/reload. It's not related to a particular viewstack from what I can tell it just seems to throw the error on certain render events. I've tried to use creationpolicy="all" on the viewstack but it seems to not be of any help. public function treeChanged(event:Event):void { selectedNode=Tree(event.target).selectedItem as XML; //trace(selectedNode.@hidden); //Alert.show([email protected]() + " *"); if([email protected]() == '' || [email protected]() == null){ //Alert.show("NULL !"); return; } mainviewstack.selectedChild = Container(mainviewstack.getChildByName([email protected]())); //Container(mainviewstack.getChildByName(selectedNode.@hidden)); If I add in an alert box before the getchildbyname option the viewstack has time to render and everything works fine, so it leads me to believe the app is not giving it enough time to load the viewstack?

  • How to run an external SWF inside a Flex Application?

    - by lk
    I want to run an Action Script 3.0 Application into a Flex Application. To do this I've done the following: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication windowComplete="loadSwfApplication()" xmlns:mx="http://www.adobe.com/2006/mxml"> <mx:Script> <![CDATA[ private function loadSwfApplication() { var urlRequest:URLRequest = new URLRequest("path/to/the/application.swf"); swfLoader.addEventListener(Event.COMPLETE, loadComplete); swfLoader.load(urlRequest); } private function loadComplete(completeEvent:Event) { var swfApplication:* = completeEvent.target.content; swfApplication.init(); // this is a Function that I made it in the Root class of swfApplication } ]]> </mx:Script> <mx:SWFLoader id="sfwLoader"/> </mx:WindowedApplication> The problem is that in the calling of swfApplication.init(); the AIR Player throws me an exception: Security sandbox violation: caller file:///path/to/the/application.swf cannot access Stage owned by app:/SWFApplicationLoader.swf. This is because somewhere in application.swf I use the stage like this: if (root.stage != null) root.stage.addEventListener(Event.REMOVED, someFunction); root.stage.stageFocusRect = false; How can I load this swf application and USE the stage without any problems?

  • GWT, MVP, and UIBinding - How to get the best of all worlds

    - by Stephane Grenier
    With MVP, you normally bind the View (UI) with the Presenter in the Presenter. However with the latest version of GWT, especially with UIBinding, you can do the following in the View: @UiHandler("loginButton") void onAboutClicked(ClickEvent event) { // my login code } Which basically exchanges a lot of anonymous inner class code for some quick annotation code. Very nice!! The problem is that this code is in the view and not the presenter... So I thought maybe: @UiHandler("loginButton") void onAboutClicked(ClickEvent event) { myPresenter.onAboutClicked(...); } But there are several problems with this approach. The most important, you blur the lines between View and Presenter. Who does which binding, in some cases it's the View, in others it's the presenter (binding to events not in your current view but that need to be attached - for example a system wide update event). You still get the benefit of being able to unit test your presenter, but at what cost. The responsibilities are messy now. For example the binding is sometimes in the View and others times in the Presenter level. I can see the code falling into all kinds of chaos with time. I also thought of extending the Presenter to the View, so that you could do this in the View. The problem here is that you lose the Presenter's ability to run standard unit tests! That's a major issue. That and the lines again become blurred. So my question, does anyone have a good method of taking advantage of the annotation from UIBinding within the MVP pattern without blurring the lines and losing the advantages of the MVP pattern?

  • Repeated properties design pattern

    - by Mark
    I have a DownloadManager class that manages multiple DownloadItem objects. Each DownloadItem has events like ProgressChanged and DownloadCompleted. Usually you want to use the same event handler for all download items, so it's a bit annoying to have to set the event handlers over and over again for each DownloadItem. Thus, I need to decide which pattern to use: Use one DownloadItem as a template and clone it as necessary var dm = DownloadManager(); var di = DownloadItem(); di.ProgressChanged += new DownloadProgressChangedEventHandler(di_ProgressChanged); di.DownloadCompleted += new DownloadProgressChangedEventHandler(di_DownloadCompleted); DownloadItem newDi; newDi = di.Clone(); newDi.Uri = "http://google.com"; dm.Enqueue(newDi); newDi = di.Clone(); newDi.Uri = "http://yahoo.com"; dm.Enqueue(newDi); Set the event handlers on the DownloadManager instead and have it copy the events over to each DownloadItem that is enqeued. var dm = DownloadManager(); dm.ProgressChanged += new DownloadProgressChangedEventHandler(di_ProgressChanged); dm.DownloadCompleted += new DownloadProgressChangedEventHandler(di_DownloadCompleted); dm.Enqueue(new DownloadItem("http://google.com")); dm.Enqueue(new DownloadItem("http://yahoo.com")); Or use some kind of factory var dm = DownloadManager(); var dif = DownloadItemFactory(); dif.ProgressChanged += new DownloadProgressChangedEventHandler(di_ProgressChanged); dif.DownloadCompleted += new DownloadProgressChangedEventHandler(di_DownloadCompleted); dm.Enqueue(dif.Create("http://google.com")); dm.Enqueue(dif.Create("http://yahoo.com")); What would you recommend?

  • Ninject InThreadScope Binding

    - by e36M3
    I have a Windows service that contains a file watcher that raises events when a file arrives. When an event is raised I will be using Ninject to create business layer objects that inside of them have a reference to an Entity Framework context which is also injected via Ninject. In my web applications I always used InRequestScope for the context, that way within one request all business layer objects work with the same Entity Framework context. In my current Windows service scenario, would it be sufficient to switch the Entity Framework context binding to a InThreadScope binding? In theory when an event handler in the service triggers it's executed under some thread, then if another file arrives simultaneously it will be executing under a different thread. Therefore both events will not be sharing an Entity Framework context, in essence just like two different http requests on the web. One thing that bothers me is the destruction of these thread scoped objects, when you look at the Ninject wiki: .InThreadScope() - One instance of the type will be created per thread. .InRequestScope() - One instance of the type will be created per web request, and will be destroyed when the request ends. Based on this I understand that InRequestScope objects will be destroyed (garbage collected?) when (or at some point after) the request ends. This says nothing however on how InThreadScope objects are destroyed. To get back to my example, when the file watcher event handler method is completed, the thread goes away (back to the thread pool?) what happens to the InThreadScope-d objects that were injected? EDIT: One thing is clear now, that when using InThreadScope() it will not destroy your object when the handler for the filewatcher exits. I was able to reproduce this by dropping many files in the folder and eventually I got the same thread id which resulted in the same exact Entity Framework context as before, so it's definitely not sufficient for my applications. In this case a file that came in 5 minutes later could be using a stale context that was assigned to the same thread before.
