  • CKEditor createFakeParserElement: writeHtml is not a function

    - by Phil Sturgeon
    I am trying to write a plugin for CKEditor that is basically just a iframe with PHP content. The user browses around, selects the video they want and then they click insert. The problem is that I need to create a "fake element" for this video, as inserting a video directly seems to show up as a Flash object, and we need to make it look a little different. I have copied together some code from the Flash plugin.js (remember this is all undocumented and uncommented) and so far come up with this: function insertFakeElement( html ) { editor = window.parent.instance; var realElement = CKEDITOR.dom.element.createFromHtml( html ); var fakeElement = editor.createFakeParserElement( realElement, 'cke_video', 'object', true ), fakeStyle = fakeElement.attributes.style || ''; var width = realElement.attributes.width, height = realElement.attributes.height; if ( typeof width != 'undefined' ) fakeStyle = fakeElement.attributes.style = fakeStyle + 'width:' + cssifyLength( width ) + ';'; if ( typeof height != 'undefined' ) fakeStyle = fakeElement.attributes.style = fakeStyle + 'height:' + cssifyLength( height ) + ';'; editor.insertHTML(fakeElement.getHtml()); } The line "giving me jip" is: var fakeElement = editor.createFakeParserElement( realElement, 'cke_video', 'object', true ), It errors here saying: l.writeHtml is not a function [Break on this error] if(o)o.addRules(l);}});})();a.editor.p..."',o,'_text" The .js file is minified and I have no idea how the source files all fit together so I can't track down the cause of this error. Does anybody know what I am doing wrong?

  • Mapping a child collection without indexing based on database primary key or using bag

    - by Colin Bowern
    I have a existing parent-child relationship I am trying to map in Fluent Nhibernate: [RatingCollection] -- [Rating] Rating Collection has: ID (database generated ID) Code Name Rating has: ID (database generated id) Rating Collection ID Code Name I have been trying to figure out which permutation of HasMany makes sense here. What I have right now: HasMany<Rating>(x => x.Ratings) .WithTableName("Rating") .KeyColumnNames.Add("RatingCollectionId") .Component(c => { c.Map(x => x.Code); c.Map(x => x.Name); ); It works from a CRUD perspective but because it's a bag it ends up deleting the rating contents any time I try to do a simple update / insert to the Ratings property. What I want is an indexed collection but not using the database generated ID (which is in the six digit range right now). Any thoughts on how I could get a zero-based indexed collection (so I can go entity.Ratings[0].Name = "foo") which would allow me to modify the collection without deleting/reinserting it all when persisting?

  • Android media thumbnails. Serious issues?

    - by Ralphleon
    I've been playing with android's thumbnails for a while now, and I've seen some inconsistencies that make me want to scream. My goal is to have a simple list of all Images (and a separate list for video) with the thumbnail and filename. Device: HTC Evo (fresh from Google I/o) First off: http://androidsamples.blogspot.com/2009/06/how-to-display-thumbnails-of-images.html That code doesn't seem to work at all, thumbnails are duplicated... some with the "mirror" effect and some without. Also some won't load and just display a black square. I've tried rebuilding the thumbnails by deleting the "alblum thumbs" directory from the SD card. HTC's gallery application seem to show everything fine. This approach seems to work: Bitmap thumb = MediaStore.Images.Thumbnails.getThumbnail( getContentResolver(), id, MediaStore.Video.Thumbnails.MICRO_KIND, null); imageView.setImageBitmap(curThumb); where id is the original images id and imageView is some image view. This is great! But, strangely, way too slow to be used inside a SimpleViewBinder. Next approach: String [] proj = {MediaStore.Images.Thumbnails._ID}; Cursor c = managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, proj, MediaStore.Images.Thumbnails.IMAGE_ID + "=" +id , null, null); if (c != null && c.moveToFirst()) { Uri thumb = Uri.withAppendedPath(mThumbUri,c.getLong(0)+""); imageView.setImageURI(thumb); } I should explain that I feel the needed WHERE condition is required because there doesn't seem to be any guarantee that your uri will have the same ID for both a thumbnail and its parent image. This works for all of the current images, but as soon as I start adding pictures with the camera they show up as blank! Debugging shows a dreaded: SkImageDecoder::Factory returned null error and the URI is returned as invalid. These are the same images that work with the previous call. Can anyone either catch my logical failure or point me to some working code?

  • Nested table height in TCPDF

    - by Kuroki Kaze
    Is it possible to make nested table fit height of its parent cell in TCPDF? My code: <?php require_once('tcpdf/config/lang/eng.php'); require_once('tcpdf/tcpdf.php'); $pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false); $pdf->setPrintHeader(false); $pdf->setPrintFooter(false); $pdf->SetFont('times', 'BI', 8); $pdf->AddPage(); $pdf->writeHTML('<table> <tr><td bgcolor="gray"> Angoisse et vif espoir, sans humeur factieuse.<br/> Plus allait se vidant le fatal sablier,<br/> Plus ma torture était âpre et délicieuse;<br/> Tout mon coeur s’arrachait au monde familier</td> <td bgcolor="lightgray">Second</td> <td bgcolor="gray">Third</td> <td> <table style="height: 100%"> <tr bgcolor="blue" style="height: 30%"><td bgcolor="yellow" style="height: 30%">Ichi</td></tr> <tr bgcolor="white" style="height: 30%"><td bgcolor="cyan" style="height: 30%">Ni</td></tr> <tr bgcolor="blue" style="height: 30%"><td bgcolor="yellow" style="height: 30%">San</td></tr> </table> </td></tr> </table>'); $pdf->Output('example_002.pdf', 'I'); ?> I want table in last cell to fill it entirely. Is there any way to do this?

  • TDD - testing business rules/validation in ASP.NET MVC

    - by csetzkorn
    Hi, I am using the sharp architecture so I can easily use mocks etc. in my unit tests and/or during TDD. I have quite complicated business rules and would like to test them at the controller level. I am just wondering how other people do this? For me validation tests business rules at three levels: (1) Property level (e.g. property is required) (2) Intra property level (e.g. start date < end date) (3) Persistence level (e.g. name is unique, parent cannot be child of child) My validation framework also assigns errors to properties. I am just wondering what other people do? Do you write a test for each business rule and check whether the correct error message is assigned to the correct property (i.e. looking at the ASP.MVC ModelState)? I hope my question makes sense. Thanks a lot! Best wishes, Christian

  • Silverlight DataForm Memory Leak

    - by Andrew Garrison
    Some Background I have noticed that setting the EditTemplate of a DataForm (from the Silverlight Toolkit) can cause the DataForm to not be garbage collected. Consequently, the parent control of the DataForm cannot be garbage collected either, causing a very significant memory leak. Here's some XAML which demonstrates the case. <toolkit:DataForm HorizontalAlignment="Stretch" Margin="10" VerticalAlignment="Stretch"> <toolkit:DataForm.EditTemplate> <DataTemplate> <toolkit:DataField Label="Dummy Binding:"> <TextBox Text="{Binding DummyBinding, Mode=TwoWay}" /> </toolkit:DataField> </DataTemplate> </toolkit:DataForm.EditTemplate> </toolkit:DataForm> I have opened an issue on CodePlex. The isssue has an attachment which has a project which desmonstrates the case. So, My Question Is Has anyone else encountered this issue? More importantly, does anyone know of any workarounds? How can I force this DataForm to be garbage collected?

  • How to add and remove nested model fields dynamically using Haml and Formtastic

    - by Brightbyte8
    We've all seen the brilliant complex forms railscast where Ryan Bates explains how to dynamically add or remove nested objects within the parent object form using Javascript. Has anyone got any ideas about how these methods need to be modified so as to work with Haml Formtastic? To add some context here's a simplified version of the problem I'm currently facing: # Teacher form (which has nested subject forms) [from my application] - semantic_form_for(@teacher) do |form| - form.inputs do = form.input :first_name = form.input :surname = form.input :city = render 'subject_fields', :form => form = link_to_add_fields "Add Subject", form, :subjects # Individual Subject form partial [from my application] - form.fields_for :subjects do |ff| #subject_field = ff.input :name = ff.input :exam = ff.input :level = ff.hidden_field :_destroy = link_to_remove_fields "Remove Subject", ff # Application Helper (straight from Railscasts) def link_to_remove_fields(name, f) f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") end def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)} \")")) end #Application.js (straight from Railscasts) function remove_fields(link) { $(link).previous("input[type=hidden]").value = "1"; $(link).up(".fields").hide(); } function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); } The problem with implementation seems to be with the javascript methods - the DOM tree of a Formtastic form differs greatly from a regular rails form. I've seen this question asked online a few times but haven't come across an answer yet - now you know that help will be appreciated by more than just me! Jack

  • CSS Div Width Problem - Lining divs... widths seem to be off in IE7

    - by jlrolin
    So far, I'm doing this programmatically using VB.net/ASP.net: 'Create Container Div Dim ContainerDiv As New HtmlGenericControl("div") ContainerDiv.Style("width") = "100%" ContainerDiv.Style("clear") = "both" ContainerDiv.Style("text-align") = "left" ContainerDiv.Style("margin") = "0" 'Create Expand/Collapse Image Dim img As New Image img.ImageUrl = Page.ResolveUrl("~/images/minus99.jpg") img.Attributes.Add("onclick", "change(this.parent);") 'Create Company Display Dim lbl As New Label lbl.Text = Parsetext(pc.NAME) lbl.Font.Bold = True lbl.Style("font-size") = "16px" Dim NameDiv As New HtmlGenericControl("div") 'NameDiv.Style("background-color") = "#F0D3D3" NameDiv.Style("width") = "375px" NameDiv.Style("float") = "left" NameDiv.Style("margin") = "0" NameDiv.Style("display") = "block" NameDiv.Controls.Add(img) NameDiv.Controls.Add(lbl) ContainerDiv.Controls.Add(NameDiv) Dim SetupDiv As New HtmlGenericControl("div") SetupDiv.Style("background-color") = "#F0D3D3" SetupDiv.Style("width") = "210px" SetupDiv.Style("float") = "left" SetupDiv.Style("margin") = "0" SetupDiv.Style("display") = "block" 'SetupDiv.Style("position") = "fixed" ContainerDiv.Controls.Add(SetupDiv) Dim UsedDiv As New HtmlGenericControl("div") UsedDiv.Style("background-color") = "#CFF5CE" UsedDiv.Style("width") = "140px" UsedDiv.Style("float") = "left" UsedDiv.Style("margin") = "0" UsedDiv.Style("display") = "block" 'UsedDiv.Style("position") = "fixed" ContainerDiv.Controls.Add(UsedDiv) Dim RemDiv As New HtmlGenericControl("div") RemDiv.Style("background-color") = "#BEE0F7" 'RemDiv.Style("position") = "absolute" RemDiv.Style("width") = "210px" RemDiv.Style("float") = "right" RemDiv.Style("padding") = "0" RemDiv.Style("margin") = "0" RemDiv.Style("display") = "block" 'RemDiv.Style("position") = "fixed" ContainerDiv.Controls.Add(RemDiv) This should give me four DIVS inside a container DIV. Here's what it's coming out as: The correct blocks above the non-inline blocks are from a table with the same exact widths as the ones I'm using on the Divs. There isn't any CSS adding pixels to them, I don't think. I need to line these up, and I can't figure out where my problem is here. Any help would be appreciated.

  • Laravel - public layout not needed in every function

    - by fischer
    I have just recently started working with Laravel. Great framework so far! However I have a question. I am using a layout template like this: public $layout = 'layouts.private'; This is set in my Base_Controller: public function __construct(){ //Styles Asset::add('reset', 'css/reset.css'); Asset::add('main', 'css/main.css'); //Scripts Asset::add('jQuery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js'); //Switch layout template according to the users auth credentials. if (Auth::check()) { $this -> layout = 'layouts.private'; } else { $this -> layout = 'layouts.public'; } parent::__construct(); } However I get an error exception now when I try to access functions in my diffrent controllers, which should not call any view, i.e. when a user is going to login: class Login_Controller extends Base_Controller { public $restful = true; public function post_index() { $user = new User(); $credentials = array('username' => Input::get('email'), 'password' => Input::get('password')); if (Auth::attempt($credentials)) { } else { } } } The error I get, is that I do not set the content of the different variables in my public $layout. But since no view is needed in this function, how do I tell Laravel not to include the layout in this function? The best solution that I my self have come a cross (don't know if this is a bad way?) is to unset($this -> layout); from function post_index()... To sum up my question: how do I tell Laravel not to include public $layout in certain functions, where a view is not needed? Thanks in advance, fischer

  • Subview of custom NSView is resizing itself to fit within its superview

    - by Jonathan Patt
    I have a custom NSView which contains a subview—for the purposes of solving this issue, the top level view is simply acting as a container and automatically resizes to fit within the window. Its subview draws a rectangle 10 pixels inset from the edge of the window, except for the bottom, which should get clipped by the window until it's resized to show the entire rectangle. It does not, however, behave as I intend, and instead shrinks the height of the rectangle when its superview has a smaller height than it does. How do I avoid this and have it stay at its proper height and instead get clipped when the superview is smaller? The parent view's implementation code is: - (id)initWithFrame:(NSRect)frameRect { self = [super initWithFrame:frameRect]; if (self) { subView = [[SubView alloc] initWithFrame:frameRect]; } return self; } - (void)drawRect:(NSRect)dirtyRect { [[NSColor grayColor] set]; [subView setFrame:NSMakeRect(10, 10, dirtyRect.size.width - 20, 500)]; [self addSubview:subView]; } - (BOOL)isFlipped { return YES; } And the subview is just: - (void)drawRect:(NSRect)dirtyRect { [[NSColor blackColor] set]; [NSBezierPath strokeRect:dirtyRect]; } - (BOOL)isFlipped { return YES; }

  • Need assistance with Kohana 3 and catch all route turning into a 404 error

    - by alex
    Based on this documentation, I've implemented a catch all route which routes to an error page. Here is the last route in my bootstrap.php Route::set('default', '<path>', array('path' => '.+')) ->defaults(array( 'controller' => 'errors', 'action' => '404', )); However I keep getting this exception thrown when I try and go to a non existent page Kohana_Exception [ 0 ]: Required route parameter not passed: path If I make the <path> segment optional (i.e. wrap it in parenthesis) then it just seems to load the home route, which is... Route::set('home', '') ->defaults(array( 'controller' => 'home', 'action' => 'index', )); The home route is defined first. I execute my main request like so $request = Request::instance(); try { // Attempt to execute the response $request->execute(); } catch (Exception $e) { if (Kohana::$environment === Kohana::DEVELOPMENT) throw $e; // Log the error Kohana::$log->add(Kohana::ERROR, Kohana::exception_text($e)); // Create a 404 response $request->status = 404; $request->response = Request::factory(Route::get('default')->uri())->execute(); } $request->send_headers(); echo $request->response; This means that the 404 header is sent to the browser, but I assumed by sending the request to the capture all route then it should show the 404 error set up in my errors controller. <?php defined('SYSPATH') or die('No direct script access.'); class Controller_Errors extends Controller_Base { public function before() { parent::before(); } public function action_404() { $this->bodyClass[] = '404'; $this->internalView = View::factory('internal/not_found'); $longTitle = 'Page Not Found'; $this->titlePrefix = $longTitle; } } Why won't it show my 404 error page?

  • How can I tell the Data Annotations validator to also validate complex child properties?

    - by GWB
    Can I automatically validate complex child objects when validating a parent object and include the results in the populated ICollection<ValidationResult>? If I run the following code: using System; using System.Collections.Generic; using System.ComponentModel.DataAnnotations; namespace ConsoleApplication1 { public class Person { [Required] public string Name { get; set; } public Address Address { get; set; } } public class Address { [Required] public string Street { get; set; } [Required] public string City { get; set; } [Required] public string State { get; set; } } class Program { static void Main(string[] args) { Person person = new Person { Name = null, Address = new Address { Street = "123 Any St", City = "New York", State = null } }; var validationContext = new ValidationContext(person, null, null); var validationResults = new List<ValidationResult>(); var isValid = Validator.TryValidateObject(person, validationContext, validationResults); Console.WriteLine(isValid); validationResults.ForEach(r => Console.WriteLine(r.ErrorMessage)); Console.ReadKey(true); } } } I get the following output: False The Name field is required. But I was expecting something similar to: False The Name field is required. The State field is required.

  • DirectX Desktop

    - by Jonathan
    Hi. I'd like to make an animated desktop background for Windows 7 using DirectX. I'm using C#, SlimDX and a couple of P/Invoke imports of Windows API functions. I'm not brilliant with native Windows programming, but I've had a poke around online and I believe what I need to do is either: 1) Find the handle of the window containing the dekstop wallpaper, hook it up to a DirectX device and draw into it. 2) Make a new output window, and insert it above the desktop wallpaper but below the desktop icons. I've tried both these, but neither seems to work. If I navigate the Window heirarchy starting from the handle returned by GetDesktopWindow(), I can go Desktop - WorkerW - SHELLDLL_DefView - SysListView32. If I hook up a DirectX device to this handle, I can draw over the entire desktop, but it also covers the icons. If I create a Windows form, set its parent to SHELLDLL_DefView using SetParent() and then use SetWindowPos to play with its Z-order I can only seem to get it to go either behind the desktop wallpaper or in front of the desktop + icons. It looks as though the desktop wallpaper is background to the folder view containing the icons, and therefore what I am trying to do cannot work. The only solution then would be to not use the desktop for icons, or to find some alternative, e.g. overwriting the desktop then overlaying a transparent window containing a view of the contents of some folder. Does anyone have any idea of what I should be doing, or even whether what I want to do is possible? It seems you can draw to the desktop background using the GDI (as I believe the wxSnow program does), and I've seen something similar to what I want done by VLC Media Player under Windows XP with its DirectX wallpaper mode (interestingly, I can't seem to get this option enabled on my system). Thanks!

  • Manditory read-only fields in django

    - by jamida
    I'm writing a test "grade book" application. The models.py file is shown below. class Student(models.Model): name = models.CharField(max_length=50) parent = models.CharField(max_length=50) def __unicode__(self): return self.name class Grade(models.Model): studentId = models.ForeignKey(Student) finalGrade = models.CharField(max_length=3) I'd like to be able to change the final grade for several students in a modelformset but for now I'm just trying one student at a time. I'm also trying to create a form for it that shows the student name as a field that can not be changed, the only thing that can be changed here is the finalGrade. So I used this trick to make the studentId read-only. class GradeROForm(ModelForm): studentId = forms.ModelChoiceField(queryset=Student.objects.all()) def __init__(self, *args, **kwargs): super(GradeROForm,self).__init__(*args, **kwargs) instance = getattr(self, 'instance', None) if instance and instance.id: self.fields['studentId'].widget.attrs['disabled']='disabled' def clean_studentId(self): instance = getattr(self,'instance',None) if instance: return instance.studentId else: return self.cleaned_data.get('studentId',None) class Meta: model=Grade And here is my view: def modifyGrade(request,student): student = Student.objects.get(name=student) mygrade = Grade.objects.get(studentId=student) if request.method == "POST": myform = GradeROForm(data=request.POST, instance=mygrade) if myform.is_valid(): grade = myform.save() info = "successfully updated %s" % grade.studentId else: myform=GradeROForm(instance=mygrade) return render_to_response('grades/modifyGrade.html',locals()) This displays the form like I expect, but when I hit "submit" I get a form validation error for the student field telling me this field is required. I'm guessing that, since the field is "disabled", the value is not being reported in the POST and for reasons unknown to me the instance isn't being used in its place. I'm a new Django/Python programmer, but quite experienced in other languages. I can't believe I've stumbled upon such a difficult to solve problem in my first significant django app. I figure I must be missing something. Any ideas?

  • How do I debug a crash when I run my garbage-collected app in Rosetta?

    - by Rob Keniger
    I have a Universal app which is targeting 10.5 and which uses garbage collection. I am building for ppc, i386 and x86_64. I don't have access to a physical PowerPC machine so I am trying to use Rosetta to confirm that the PowerPC portion of the app works correctly.

It looks like the Garbage Collector is failing very badly. Are garbage-collected PowerPC apps not supported in Rosetta? I can't see any mention of this limitation in the docs if so. Does anyone have any ideas?

  • ASP.NET/C# - Deserialize XML, XSD.exe created multiple classes

    - by Barryman9000
    I'm trying to deserialize some XML (returned from a web service) into an object that I created using XSD.exe. The XSD executable created a .CS file with a different partial class for each parent node in the XML. For Example, the beginning of the XML looks like this (why can't I post xml here? sorry, this is ugly): <disclaimer><notificationDescription>Additional charges will apply.</notificationDescription></disclaimer><quote><masterQuote></masterQuote></quote> And the Class generated by the XSD.exe has a partial class named disclaimer with a get; set; string for notificationDescription. And another partial class for quoteMasterQuote with the corresponding child nodes as public strings. How can I deserialize this XML file into multiple classes? I found this code, but it seems like it'll only work for one object. public static PricingResponse2 DeSerialize(string _xml) { PricingResponse2 _resp = new PricingResponse2(); StringReader _strReader = new StringReader(_xml); XmlSerializer _serializer = new XmlSerializer(_resp.GetType()); XmlReader _xmlReader = new XmlTextReader(_strReader); try { _resp = (PricingResponse2)_serializer.Deserialize(_xmlReader); return _resp; } catch (Exception ex) { string _error = ex.Message; throw; } finally { _xmlReader.Close(); _strReader.Close(); _strReader.Dispose(); } } This is the first time I've tried this, so I'm a little lost.

  • How would the conversion of a custom CMS using a text-file-based database to Drupal be tackled?

    - by James Morris
    Just today I've started using Drupal for a site I'm designing/developing. For my own site http://jwm-art.net I wrote a user-unfriendly CMS in PHP. My brief experience with Drupal is making me want to convert from the CMS I wrote. A CMS whose sole method (other than comments) of automatically publishing content is by logging in via SSH and using NANO to create a plain text file in a format like so*: head<<END_HEAD title = Audio keywords= open,source,audio,sequencing,sampling,synthesis descr = Music, noise, and audio, created by James W. Morris. parent = home END_HEAD main<<END_MAIN text<<END_TEXT Digital music, noise, and audio made exclusively with @=xlink=http://www.linux-sound.org@:Linux Audio Software@_=@. END_TEXT image=gfb@--@;Accompanying image for penonpaper-c@right ilink=audio_2008 br= ilink=audio_2007 br= ilink=audio_2006 END_MAIN info=text<<END_TEXT I've been making PC based music since the early nineties - fortunately most of it only exists as tape recordings. END_TEXT ( http://jwm-art.net/dark.php?p=audio - There's just over 400 pages on there. ) *The jounal-entry form which takes some of the work out of it, has mysteriously broken. And it still required SSH access to copy the file to the main dat dir and to check I had actually remembered the format correctly and the code hadn't mis-formatted anything (which it always does). I don't want to drop all the old content (just some), but how much work would be involved in converting it, factoring into account I've been using Drupal for a day, have not written any PHP for a couple of years, and have zero knowledge of SQL? How might a team of developers tackle this? How do-able is it for one guy in his spare time?

  • load class not in classpath dynamically in web application - without using custom classloader

    - by swdeveloper
    I am developing a web application. The web application generates java classes on the fly. For example it generates class com.people.Customer.java In my code, I dynamically compile this to get com.people.Customer.class and store in some directory say repository/com/people/Customer.class which is not on the classpath of my application server.My application server(I am using WebSphere Application Server/Apache Tomcat etc) picks up the classes from the WEB-INF/classes directory. The Classloader would use this to load the classes. After compilation I need to load this class so that it becomes accessible to other classes using it after its creation. 4.When I use Thread.currentThread().getContextClassLoader().loadClass(com.people.Customer) obviously the Classloader is not able to load the class, since its not on the classpath(not in WEB-INF/classes). Due to similar reasons, getResource(..) or getResourceAsStream(..) also does not work. I need a way to : Read the class Customer.class maybe as a stream (or any other way would do) and then load it. Following are the constraints: I cannot add the repository folder to the WEB-INF/classes folder. I cannot create a new Custom ClassLoader. If I create a new ClassLoader and this loads the class, it will not be accessible to its parent ClassLoader. Is there any way of achieving this? If not this, in the worse case, is there a way of overriding the default class loader with a custom class loader for web applications the same classloader should be used to load applications throughout entire lifecycle of my web application. Appreciate any solution :)

  • PHP forking and mysql database connection problem

    - by user298819
    I am now trying to do forking in php. I would like to do some query and update in child process.. the problem is that whenever a child process finish, it close the connection which makes the other queries fail. The following is my sample code!! #!/usr/local/bin/php <?php set_time_limit(0); # forever program! $db = mysql_connect("server","user","pwd"); mysql_select_db("schema",$db); $sql = "query"; $res = mysql_query($sql,$db); while($rows = mysql_fetch_array($res)) { $rv = pcntl_fork(); if($rv == -1){ echo "forking failed"; }elseif($rv){ echo "parent process $rv\n"; $db = mysql_connect("192.168.8.112","zwmuser","zwmuser",true); mysql_select_db("schema",$db); }else{ echo "child process $rv\n"; $sql1 = "another query"; $res1 = mysql_query($sql1,$db); while($messages = mysql_fetch_array($res1)) { $sql2 = "update query"; mysql_query($sql2,$db); } exit(0); //it terminates both child process and mysql connection! } } ?>

  • How to get an element using inner text (Watir, Nokogir, Hpricot)

    - by Hpriguy
    I have been expeirmenting with Watir, Nokogir and Hpricot. All of these use top-down approach which is my problem. i.e. they use element type to search element. I want to find out the element using the text without knowing element type. e.g. <element1> <element2> Text2 </element2> <element3> Text3 </element3> text4 </element1> I want is to get element2 and element1 etc by searching for Text2 and Text3. Please note that I do not know if elements are divs or tr/tds or links etc. I just know the text. Algorithem should be something like : iterated through all the elements, match inner text, if match get me the element and the parent element. Let me kow if this is possible in any way?

  • how to create and track multiple pairs "View-ViewModel"?

    - by Gianluca Colucci
    Hi! I am building an application that is based on MVVM-Light. I am in the need of creating multiple instances of the same View, and each one should bind to its own ViewModel. The default ViewModelLocator implements ViewModels as singletons, therefore different instances of the same View will bind to the same ViewModel. I could create the ViewModel in the VMLocator as a non-static object (as simple as returning new VM()...), but that would only partially help me. In fact, I still need to keep track of the opened windows. Nevertheless, each window might open several other windows (of a different kind, though). In this situation I might need to execute some operation on the parent View and all its children. For example before closing the View P, I might want to close all its children (view C1, view C2, etc.). Hence, is there any simple and easy way to achieve this? Or is there any best practice you would advice me to follow? Thanks in advance for your precious help. Cheers, Gianluca.

  • Displaying Many-To-Many Database relationship in VB.NET 2008 with DataGrid, MS SQL 2008

    - by user337501
    Computer bombed while posting this, couldnt find a duplicate question but if there is one, forgive me. So, I've run into a wall. And rather than use a ladder to avoid it, I'd like go through it. I'm setting up what I can best describe as a many-to-many relationship in a database. To examplify, imagine I have three primary tables: Items, Categories, Sections(nevermind the potential redundancy) Then I have another table, Properties. Items, Categories, and Sections can be associated with many properties. A single property can be associated with one, all, or none of the other tables. The best way I can figure to do this is to have join tables make the relationship. i.e. tblItems----(Foreign Key)----tblItems_To_Properties----(Foreign Key)----tblProperties In this example, tblItems simply has an "ItemID" Primary Key. tblItems_To_Properties has its own Primary Key(tblItems_To_PropertiesID), a Foreign Key to the Item(ItemID) and a Foreign key to the Property(PropertyID). The Properties table simply has its primary key(PropertyID) I hope this example isnt too confusing...if I have to I can find a way to put a diagram up or something. My problem is, I want to display this in a DataGrid using the Master-Detail method(DevExpress GridControl). I use the tblItems as a test, and I can see the Items in the parent view, but in the child view I see(understandably) the join table and that is it. My goal is to make it so the Grid ignores the join table and shows the Properties table as the only child. Any help on this method or insight into another solution would be muuuuuuuch appreciat

  • WPF performance on scaling a large scene

    - by Mark
    I have a full screen app that I want to be able to zoom in on certain areas. I have the code working fine, but I notice that when I get closer in, the zoom in animation (which animates the ScaleTransform.ScaleX and ScaleTransform.ScaleY properties on a Parent canvas) starts to jerk down a little and the frame rate suffers. Im not using any BitmapEffects or anything, and ideally I would like my scene to get more complicated than it currently already is. The scene is quite large, 1980x1024, this is a requirement and cannot be changed. The current layout is like this: <Canvas x:name="LayoutRoot"> <Canvas x:Name="ContainerCanvas"> <local:MyControl x:Name="c1" /> <!-- numerous or ther controls and elements that compose the scene --> </Canvas> </Canvas> The code that zooms in just animates the RenderTransform of the ContainerCanvas, which in tern, scales its children which gives the desired effect. However, Im wondering if I need to swap out the ContainerCanvas for a ViewBox or something like that? Ive never really worked with ViewBox/Viewport controls before in WPF can they even help me out here? Smooth zooming is a huge requirement of the client and I must get this resolved. All ideas are welcome Thanks a lot Mark
