• css display:table first column too wide

  - by Mestore

  I have a css table setup like this: <div class='table'> <div> <span>name</span> <span>details</span> </div> </div> The css for the table is: .table{ display:table; width:100%; } .table div{ text-align:right; display:table-row; border-collapse: separate; border-spacing: 0px; } .table div span:first-child { text-align:right; } .table div span { vertical-align:top; text-align:left; display:table-cell; padding:2px 10px; } As it stands the two columns are split evenly between the space occupied by the width of the table. I'm trying to get the first column only to be as wide as is needed by the text occupying it's cells The table is an unknown width, as are the columns/cells.

• QT: trouble with qobject_cast

  - by weevilo

  I have derived QGraphicsItem and QGraphicsScene classes. I want the items to be able to call scene() and get a derviedGraphicsItem * instead of a QGraphicsItem *, so I reimplemented QGraphicsScene::itemAt to return a derived pointer. DerivedItem* DerivedScene::itemAt( const QPointF &position, const QTransform &dt ) const { return qobject_cast< DerivedItem * >( QGraphicsScene::itemAt(position, dt) ); } I get the following error (Qt 4.6, GCC 4.4.3 on Ubuntut 10.4) scene.cpp: In member function ‘DerivedItem* DerivedScene::itemAt(qreal, qreal, const QTransform&) const’: scene.cpp:28: error: no matching function for call to ‘qobject_cast(QGraphicsItem*)’ I then noticed QGraphicsItem doesn't inherit QObject, so I made my derived QGraphicsItem class have multiple inheritance from QObject and QGraphicsItem, and after adding the Q_OBJECT macro and rebuilding the project I get the same error. Am I going about this the wrong way? I know it's supposed to be bad design to try to cast a parent class as a child, but in this case it seems like what I want, since my derived item class has new functionality and its objects need a way to call that new functionality on items around themselves, and asking the items scene object with itemAt() seems like the best way - but I need itemAt() to return a pointer of the right type. I can get around this by having the derived items cast the QGraphicsItem * returned by QGraphicsScene::itemAt() using dynamic_cast, but I don't really understand why that works and not qobject_cast, or the benefits or disadvantages to using dynamic_cast vs. qobject_cast.

• How to access WCF RIA service from Windows Service?

  - by Duncan Bayne

  I have a functioning SL4 application; inside the ClientBin directory I have an .svc file that describes my service: <% @ServiceHost Service="MyApp.Services.MyServiceFactory="System.ServiceModel.DomainServices.Hosting.DomainServiceHostFactory" %> When I browse to http://localhost:52878/ClientBin/MyApp-Services-MyService.svc I see the following: "You have created a service. To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax: svcutil.exe http://localhost:52878/ClientBin/MyApp-Services-MyService.svc?wsdl" I want to access that service from a Windows Service application. My understanding is that I need to enable SOAP end-points in order to make this happen. So, I add the following to my web.config file: <domainServices> <endpoints> <add name="soap" type="System.ServiceModel.DomainServices.Hosting.SoapXmlEndpointFactory, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" /> </endpoints> </domainServices> Firstly, Intellisense complains about the presence of the tag, saying "The element system.ServiceModel has invalid child element domainServices." Secondly, the aforementioned Silverlight application stops working, presumably because this change breaks the underlying web services. Thirdly, it appears that the System.ServiceModel.DomainServices.Hosting assembly doesn't actually contain the SoapXmlEndpointFactory type; if I try to browse to the service after adding the above to web.config I see: "Could not load type 'System.ServiceModel.DomainServices.Hosting.SoapXmlEndpointFactory' from assembly 'System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'." If I inspect the assembly using Reflector, I see that it contains the DomainServiceEndpointFactory and PoxBinaryEndpointFactory types, but no SoapXmlEndpointFactory. Could someone please let me know what I'm doing wrong? I can't believe that it should be this hard to simply consume a WCF RIA service in something other than a Silverlight application! Yours, Duncan Bayne

• UISplitViewController and complex view heirarchy

  - by Jasconius

  I'm doing an iPad tech demo and I'm running into a serious technical problem. I have an app concept that leverages UISplitViewController, but NOT as the primary controller for the entire app. The app flow could be described roughly as this: Home screen (UIViewController) List-Detail "Catalog" (UISplitViewController) Super Detail Screen (UIViewController but could conceivable also be a child of SplitView). The problem is in the flow between Home and Catalog. Once a UISplitViewController view is added to the UIWindow, it starts to throw hissy fits. The problem can be summarized at this: When a UISplitView generates a popover view, it appears to then be latched to its parent view. Upon removing the UISplitView from the UIWindow subviews, you will get a CoreGraphics exception and the view will fail to be removed. When adding other views (presumably in this case, the home screen to which you are returning), they do not autorotate, instead, the UISplitView, which has failed to be removed due to a CG exception, continues to respond to the rotation instead, causing horrible rendering bugs that can't be just "dealt with". At this point, adding any views, even re-adding the SplitView, causes a cascade of render bugs. I then tried simply to leave the SplitView ever present as the "bottom" view, and keeping adding and removing the Home Screen from on top of it, but this fails as SplitView dominates the Orientation change calls, and Home Screen will not rotate, even if you call [homeScreen becomeFirstResponder] You can't put SplitView into a hierarchy like UINavigationController, you will get an outright runtime error, so that option is off the table. Modals just look bad and are discourages anyway. My presumption at this moment is that the only proper way to deal with this problem is so somehow "disarm" UISplitViewController so that it can be removed from its parent view without throwing an unhandled exception, but I have no idea how. If you want to see an app that does exactly what I need to do, check out GILT Groupe in the iPad app store. They pulled it off, but they seem to have programmed an entire custom view transition set. Help would be greatly appreciated.

• Self-reference entity in Hibernate

  Hi guys, I have an Action entity, that can have other Action objects as child in a bidirectional one-to-many relationship. The problem is that Hibernate outputs the following exception: "Repeated column in mapping for collection: DbAction.childs column: actionId" Below the code of the mapping: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="DbAction" table="actions"> <id name="actionId" type="short" /> <property not-null="true" name="value" type="string" /> <set name="childs" table="action_action" cascade="all-delete-orphan"> <key column="actionId" /> <many-to-many column="actionId" unique="true" class="DbAction" /> </set> <join table="action_action" inverse="true" optional="false"> <key column="actionId" /> <many-to-one name="parentAction" column="actionId" not-null="true" class="DbAction" /> </join> </class> </hibernate-mapping>

• Problems with Prism hosted in a WinForm ElementHost

  - by rabozo

  I am having problems with hosting a WPF prism app in an ElementHost control and am desparate for help. The PRISM app runs fine in silverlight and in a standalone WPF. The main Shell seems to setup fine in the elementHost on a WinForm however other views only load with the “RegisterViewWithRegion” and not the “Add,Activate” procedure. I need “Add,Activate” for scoping. However I beleive the problem is that I am loading my shell twice … not on purpose. I cannot find a way to call the bootsrapper and set the elementHot without calling “Resolve” twice. Here is the code for my WinForm and my bootstrapper. Again everything works when using "RegisterViewWithRegion". Here is the Winform Constructor: public Form1() { InitializeComponent(); if (System.Windows.Application.Current == null) { new MyApp(); } Bootstrapper bootStrapper = new Bootstrapper(); bootStrapper.Run(); var shellElement = bootStrapper.Container.Resolve<ShellContainer>(); //Attach the WPF control to the host elementHost.Child = shellElement; } Here is the bootstrapper: public class Bootstrapper : UnityBootstrapper { protected override DependencyObject CreateShell() { return Container.Resolve<ShellContainer>(); } protected override void InitializeModules() { IModule moduleSurvey = Container.Resolve<SurveyModule>(); moduleSurvey.Initialize(); } }

• Expose NativeActivity Variables to Workflow Designer

  I've got a NativeActivity which contains an Activity body. The purpose of this activity is to expose a resource for the duration of the child activity as a Variable. The problem I've encountered is it appears the Variable cannot be used outside the activity. I'll use StreamReader as an example resource. ResourceActivity.cs: [Designer(typeof(ResourceActivityDesigner))] public sealed class ResourceActivity : NativeActivity { [RequiredArgument] public InArgument<string> Path { get; set; } [Browsable(false), EditorBrowsable(EditorBrowsableState.Never)] public Activity Body { get; set; } [Browsable(false), EditorBrowsable(EditorBrowsableState.Never)] public Variable<StreamReader> Resource { get; set; } public ResourceActivity() { this.Resource = new Variable<StreamReader> { Default = null, Name = "reader" }; } protected override void CacheMetadata(NativeActivityMetadata metadata) { if (this.Path != null) metadata.AddArgument(this.Path); if (this.Body != null) metadata.AddChild(this.Body); if (this.Resource != null) metadata.AddVariable(this.Resource); } protected override void Execute(NativeActivityContext context) { this.Resource.Set(context, new StreamReader(this.Path.Get(context))); context.ScheduleActivity(this.Body, new completionCallback(Done), new FaultCallback(Faulted)); } private void Done(NativeActivityContext context, ActivityInstance instance) { var reader = this.Reader.Get(context); if (reader != null) reader.Dispose(); } private void Faulted(NativeActivityFaultContext context, Exception ex, ActivityInstance instance) { var reader = this.Reader.Get(context); if (reader != null) reader.Dispose(); } } I cannot view "Resource" or "reader" in the Variables list in the Workflow Designer. Am I missing something in CacheMetadata?

• Could not find schema information for the element 'castle'.

  - by Richard77

  Hello! I'm creating a Custom tag in my web.config. I first wrote the following entry under the configSections section. <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor" /> But, when I try to create a castle node inside the configuration node as below <castle> <components> </components> </castle> I get the following error message:"*Could not find schema information for the element 'castle*'." "*Could not find schema information for the element 'components'***." Am I missing something? I can't find why. And, if I run the application anyway, I get the following error "Could not find section 'Castle' in the configuration file associated with this domain." Ps.// The sample comes from "Pro ASP.NET MVC Framework"/Steven Sanderson/APress ISBN-13 (pbk): 978-1-4302-1007-8" on page 99. Thank you for the help ============================================================ Since I believe to have done exactly what's said in the book and did not succed, I ask the same question in different terms. How do I add a new node using the above information? ============================================================================= Thank you. I did what you said and do not have the two warnings. However, I've go a big new warning: "The element 'configuration' in namespace 'MyWindsorSchema' has invalid child element 'configSections' in namespace 'MyWindsorSchema'.

• DDD/NHibernate Use of Aggregate root and impact on web design - ex. Editing children of aggregate ro

  - by pbrophy

  Hopefully, this fictitious example will illustrate my problem: Suppose you are writing a system which tracks complaints for a software product, as well as many other attributes about the product. In this case the SoftwareProduct is our aggregate root and Complaints are entities that only can exist as a child of the product. In other words, if the software product is removed from the system, so shall the complaints. In the system, there is a dashboard like web page which displays many different aspects of a single SoftwareProduct. One section in the dashboard, displays a list of Complaints in a grid like fashion, showing only some very high level information for each complaint. When an admin type user chooses one of these complaints, they are directed to an edit screen which allows them to edit the detail of a single Complaint. The question is: what is the best way for the edit screen to retrieve the single Complaint, so that it can be displayed for editing purposes? Keep in mind we have already established the SoftwareProduct as an aggregate root, therefore direct access to a Complaint should not be allowed. Also, the system is using NHibernate, so eager loading is an option, but my understanding is that even if a single Complaint is eager loaded via the SoftwareProduct, as soon as the Complaints collection is accessed the rest of the collection is loaded. So, how do you get the single Complaint through the SoftwareProduct without incurring the overhead of loading the entire Complaints collection?

• Synchronize the position of two ScrollView views

  - by Billy

  I am trying to synchronize the positions of two ScrollViews. I'm trying to do this to display a tv guide listing. I have created a custom class that extends RelativeLayout to display the guide. This relative layout has four children: an imageview in the top left corner, a HorizontalScrollView to display the column headers in the top right, a ScrollView to display the row headers at the bottom left, and a ScrollView in the bottom right that contains the listings. This ScrollView then contains a HorizontalScrollView, which in turn contains a LinearLayout with multiple child views that display the data. I hope this explains it clearly, but here's a diagram to make it clearer: ____________ |__|___hsv___| | | | | | sv -> | | | hsv -> | |sv| ll -> | | | etc | | | | |__|_________| I set it up like this because I wanted the guide listings to scroll both horizontally and vertically, but there's no scroll view that does this. Also, I want the row and column headers to display no matter what position the guide listings are at, but I want them to be lined up properly. So I'm trying to find a way to synchronize the positions of the two hsv's, and to also synchronize the positions of the two sv's. I'm also trying to do it in a way that avoids just running a handler every few milliseconds to poll one view and call scrollTo on the other. I'm in no way sure that this is the best way to do it, but this is what I've come up with. If anybody has any other suggestions, please feel free!

• Binding a TreeView with ContextMenu in Xaml

  - by Michael Stoll

  I'm pretty new to Xaml and need some advise. A TreeView should be bound to a hierarchical object structure. The TreeView should have a context menu, which is specific for each object type. I've tried the following: <TreeView> <TreeView.Resources> <DataTemplate x:Key="RoomTemplate"> <TreeViewItem Header="{Binding Name}"> <TreeViewItem.ContextMenu> <ContextMenu> <MenuItem Header="Open" /> <MenuItem Header="Remove" /> </ContextMenu> </TreeViewItem.ContextMenu> </TreeViewItem> </DataTemplate> </TreeView.Resources> <TreeViewItem Header="{Binding Name}" Name="tviRoot" IsExpanded="True" > <TreeViewItem Header="Rooms" ItemsSource="{Binding Rooms}" ItemTemplate="{StaticResource RoomTemplate}"> <TreeViewItem.ContextMenu> <ContextMenu> <MenuItem Header="Add room"></MenuItem> </ContextMenu> </TreeViewItem.ContextMenu> </TreeViewItem> </TreeViewItem> But with this markup the behavior is as intended, but the child items (the rooms) are indented too much. Anyway all the bining samples I could find use TextBlock instead of TreeViewItem in the DataTemplate, but wonder how to integrate the ContextMenu there.

• Flex 3 : UIComponent.addChild issue

  - by Frank

  Hello SOers, I've run into a nice problem with the UIComponent.addChild(...) function. First of all, I'm using ESRI Api for Flex. In this API you find a class called Graphic that inherits UIComponent. Basically, I'm trying to add, as a child, a Graphic 'g' to another graphic 'parent'. So that when you delete the 'parent' graphic the 'g' graphic deletes as well. private function writeMeasurements(parent:Graphic):void { var g:Graphic; if(parent.geometry.extent != null) g = new Graphic(parent.geometry.extent.center); else g = new Graphic(parent.geometry); g.initialize(); g.name = UIDUtil.createUID(); g.symbol = txtSym; graphicsLayer.add(g); parent.addChild(g); } graphicsLayer class This code actually runs pretty fine. The problem is after... it's like if the addChild function was asynchronious. This is the error I get : TypeError: Error #1009: Il est impossible d'accéder à la propriété ou à la méthode d'une référence d'objet nul. at com.esri.ags::Graphic/updateDisplayList()[C:\checkout\flex_api\api\src\com\esri\ags\Graphic.as:346] at mx.core::UIComponent/validateDisplayList() at mx.managers::LayoutManager/validateDisplayList() at mx.managers::LayoutManager/doPhasedInstantiation() at Function/http://adobe.com/AS3/2006/builtin::apply() at mx.core::UIComponent/callLaterDispatcher2() at mx.core::UIComponent/callLaterDispatcher() I know this is a very specific question, but I think you guys are the BEST!

• Duplicate a collection of entities and persist in Hibernate/JPA

  - by Michael Bavin

  Hi, I want to duplicate a collection of entities in my database. I retreive the collection with: CategoryHistory chNew = new CategoryHistory(); CategoryHistory chLast = (CategoryHistory)em.createQuery("SELECT ch from CategoryHistory ch WHERE ch.date = MAX(date)").getSingleResult; List<Category> categories = chLast.getCategories(); chNew.addCategories(categories)// Should be a copy of the categories: OneToMany Now i want to duplicate a list of 'categories' and persist it with EntityManager. I'm using JPA/Hibernate. UPDATE After knowing how to detach my entities, i need to know what to detach: current code: CategoryHistory chLast = (CategoryHistory)em.createQuery("SELECT ch from CategoryHistory ch WHERE ch.date=(SELECT MAX(date) from CategoryHistory)").getSingleResult(); Set<Category> categories =chLast.getCategories(); //detach org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession(); session.evict(chLast);//detaches also its child-entities? //set the realations chNew.setCategories(categories); for (Category category : categories) { category.setCategoryHistory(chNew); } //set now create date chNew.setDate(Calendar.getInstance().getTime()); //persist em.persist(chNew); This throws a failed to lazily initialize a collection of role: entities.CategoryHistory.categories, no session or session was closed exception. I think he wants to lazy load the categories again, as i have them detached. What should i do now?

• WPF creating custom control - creating control like SpinBox extending TextBox

  - by veedoo

  Hi, What is the best way to extend a control? Lets choose for example SpinBox - we want to extend TextBox to SpinBox - just to add two buttons on the right side, which each one on click checks if Text property is a valid number and if it is increases or decreases the value by 1. Suposse that we have a lot of code using TextBox (Text, IsReadOnly properties and bindings etc.) so we want to replace TextBox by SpinBox without touching rest of the code. 1) we can inherit TextBox - so we have exactly the same interface, but how to add the buttons ?? 2) we can inherit from some layout control - eg. DockPanel - we can add buttons, but we lose TextBox interface. 3) after quick read about ControlTemplates I'm not sure, but I believe that we can add buttons and their logic using ControlTemplates 4) like about templates I'm not sure, but I hope we can inherit decorator class to create decorator with the buttons - we lose interface, but can add TextBox as a child I think that the best solutions is to combine 3) and 4) - create a decorator class and use it in a control template for TextBox. I would be grateful for your ideas and simple code how to implement 3 and 4, especially with code (c#), not xaml. Regards

• Ruby on Rails: Using XML Builder Partials

  - by randombits

  Partials in XML builder are proving to be non-trivial. After some initial Google searching, I found the following to work, although it's not 100% xml.foo do xml.id(foo.id) xml.created_at(foo.created_at) xml.last_updated(foo.updated_at) foo.bars.each do |bar| xml << render(:partial => 'bar/_bar', :locals => { :bar => bar }) end end this will do the trick, except the XML output is not properly indented. the output looks something similar to: <foo> <id>1</id> <created_at>sometime</created_at> <last_updated>sometime</last_updated> <bar> ... </bar> <bar> ... </bar> </foo> The <bar> element should align underneath the <last_updated> element, it is a child of <foo> like this: <foo> <id>1</id> <created_at>sometime</created_at> <last_updated>sometime</last_updated> <bar> ... </bar> <bar> ... </bar> </foo> Works great if I copy the content from bar/_bar.xml.builder into the template, but then things just aren't DRY.

• Windows Forms Host + System.Windows.Forms.DataVisualization.Chart

  - by dark-elf2

  Good day all I have the following question: I would like to use Chart from Windows Forms due to the fact that it allows to build much more types of graphical visualisation that one from WPF Toolkit does. So, I am adding Chart control for Windows Forms as a child element into the WindowsFormsHost. But, when I run the application I and all my clients see only white area. Though, any other Windows Forms Control works great in Windows Forms Host. What is wrong with the Chart control? Here is the XAML code <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:wfi="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration" xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms" xmlns:CHR="clr-namespace:System.Windows.Forms.DataVisualization.Charting;assembly=System.Windows.Forms.DataVisualization" Title="Window1" Height="300" Width="300"> <Grid> <wfi:WindowsFormsHost x:Name="mainFGrid" > <CHR:Chart x:Name="mainChart" /> </wfi:WindowsFormsHost> </Grid> </Window> Kind regards, Anatoliy Sova

• Keyboard Animation Issues When Calling becomeFirstResponder within a Modal View Controller

  - by LucasTizma

  I've been having some issues with calling -becomeFirstResponder on a UITextField contained with a view controller that is presented modally. I call this method in the modal view controller's -viewDidLoad method so that the keyboard is immediately displayed. What I expected is for both the keyboard and the modal view controller to animate from up the bottom of the screen at the same time. However, what I'm observing is the following: There is a ~0.2 second UI lag between clicking the button that calls the -presentModalViewController:animated: method on the parent view controller and when the child view controller begins to animate modally. The keyboard is immediately presented with absolutely no animation about half-way through the modal view controller's animation. Once the modal view controller's animation is complete, everything else seems to operate smoothly. Dismissing the modal view controller results in it being smoothly animated off screen (along with the keyboard, coincidentally). It's as if the keyboard's animation and the modal view controller's animation are both competing for some lower-level Core Animation resource at the same time, but I don't see why this should be happening. What further seems to corroborate this hunch is if I don't ask the UITextField to become the first responder (i.e., if I don't ask the keyboard to present itself), then there is absolutely no UI lag, and the modal view controller animates instantly. Interestingly, if I do something like [self.textField performSelector:@selector(becomeFirstResponder) withObject:nil afterDelay:0.0001]; then the animation of the keyboard happens nearly at the same time as the modal view controller's animation -- it's extremely difficult to tell that they aren't both being animated at the exact same time. Furthermore, there's no more UI lag. Has anyone experienced anything similar to this?

• Custom jQuery Gallery Thumbnail Behavior

  - by steve

  I recently got some help on here from SLaks (thank you) on the behavior of my custom gallery. I'm now trying to fix the way the thumbnails function. I've been toying with it for about an hour but I can't get it to work. Live version of the code: http://www.studioimbrue.com . Currently the code is as follows: $('.thumbscontainer ul li a').click(function() { var li_index = $(this).parents('ul').children('li').index($(this).parent("li")); $(this).parents('.thumbscontainer').parent().find('.captions ul li').fadeOut(); $(this).parents('.thumbscontainer').parent().find('.captions ul li:eq('+li_index+')').fadeIn(); }); $('.container .captions li').click(function() { var nextLi = $(this).fadeOut().next().fadeIn(); if (nextLi.length === 0) //If we're the last one, nextLi = $(this).siblings(':first-child').fadeIn(); }); The only problem is that when the gallery image is clicked, it goes to the next image in the series, yet the thumbnails do not change to the next one in the list. You can take a look at my previous question to see our discussion. Thanks

• MFMailComposeController crashing non-deterministically

  Hello, I've been struggling with this issue for a few days. I am trying to use the MFMailComposeController to send emails. What's happening is that the program crashes (long stack-trace below) upon clicking the SEND button. However, this is non-deterministic - sometimes it works immediately, sometimes after a long delay, and most often, it crashes. Here's my code for sending: -(void)mailWithAttachment:(NSString *) fileName type:(NSString*) attachmentType data:(NSData *) attachmentData { MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init]; mc.mailComposeDelegate = self; if ([MFMailComposeViewController canSendMail]) { [mc setSubject:@"my subject"]; [mc setMessageBody:@"my body" isHTML:YES]; [mc addAttachmentData:attachmentData mimeType:attachmentType fileName:fileName]; [self presentModalViewController:mc animated:YES]; } [mc release]; } didFinish result looks like you'd imagine: -(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { [self dismissModalViewControllerAnimated:YES]; //...some other actions here for other UI logic, but problem persists if removed } And the definition of the class: @interface ShareViewController : UIViewController { //... } Here's the stack trace: #0 0x33568534 in gdb_objc_debuggerModeFailure #1 0x3356634e in _rwlock_write_nodebug #2 0x33560940 in map_images #3 0x2fe0413e in __dyld__ZN4dyldL18notifyBatchPartialE17dyld_image_statesbPFPKcS0_jPK15dyld_image_infoE #4 0x2fe042d4 in __dyld__ZN4dyldL11notifyBatchE17dyld_image_states #5 0x2fe0aee0 in __dyld__ZN11ImageLoader4linkERKNS_11LinkContextEbbRKNS_10RPathChainE #6 0x2fe062d6 in __dyld__ZN4dyld4linkEP11ImageLoaderbRKNS0_10RPathChainE #7 0x2fe08188 in __dyld_dlopen #8 0x30c18fd0 in dlopen #9 0x0000390c in <function called from gdb> #10 0x3356628e in getMethodNoSuper_nolock #11 0x335662b8 in _class_getMethodNoSuper_nolock #12 0x3356518a in lookUpMethod #13 0x33562914 in _class_lookupMethodAndLoadCache #14 0x3356264a in objc_msgSend_uncached #15 0x33562a2a in _class_initialize #16 0x33567dfe in prepareForMethodLookup #17 0x33565168 in lookUpMethod #18 0x33562914 in _class_lookupMethodAndLoadCache #19 0x3356264a in objc_msgSend_uncached #20 0x32b2c288 in +[NSTimeZone(NSTimeZone) defaultTimeZone] #21 0x32b2c246 in -[NSCalendarDate initWithTimeIntervalSinceReferenceDate:] #22 0x32b3beb4 in -[NSDate(NSCalendarDateStuff) descriptionWithCalendarFormat:timeZone:locale:] #23 0x323642fc in -[NSDate(Goodies) descriptionForMimeHeaders] #24 0x32a6e812 in -[MailComposeController headersUseSuspendInfo:] #25 0x32a71e38 in -[MailComposeController messageUseSuspendInfo:endingEditing:] #26 0x32a6e594 in -[MailComposeController _getMessage:] #27 0x32a6e536 in -[MailComposeController message] #28 0x32a72bcc in -[MailComposeController deliverMessageRemotely] #29 0x32a7cab0 in -[_MFMailComposeRootViewController mailComposeControllerCompositionFinished:] #30 0x32a6e0a0 in -[MailComposeController sendMessage] #31 0x32a7086a in -[MailComposeController send:] #32 0x32c29ffa in -[NSObject performSelector:withObject:] #33 0x32a661cc in -[MailComposeView _sendButtonClicked:] I've tried the MFMailComposeController as a child of different views with the same result.

• C#.NET Forms programing - Modal and Non-Modal forms problem

  - by Povilas

  Hello, I have a problem with modality of the forms under C#.NET. Let's say I have main form #0 (see the image below). This form represents main application form, where user can perform various operations. However, from time to time, there is a need to open additional non-modal form to perform additional main application functionality supporting tasks. Let's say this is form #1 in the image. On this #1 form there might be opened few additional modal forms on top of each other (#2 form in the image), and at the end, there is a progress dialog showing a long operation progress and status, which might take from few minutes up to few hours. The problem is that the main form #0 is not responsive until you close all modal forms (#2 in the image). I need that the main form #0 would be operational in this situation. However, if you open a non-modal form in form #2, you can operate with both modal #2 form and newly created non modal form. I need the same behavior between the main form #0 and form #1 with all its child forms. Is it possible? Or am I doing something wrong? Maybe there is some kind of workaround, I really would not like to change all ShowDialog calls to ShowDialog... Thanks, Povilas

• gunit syntax for tree walker with a flat list of nodes

  - by Kaleb Pederson

  Here's a simple gunit test for a portion of my tree grammar which generates a flat list of nodes: objectOption walks objectOption: <<one:"value">> -> (one "value") Although you define a tree in ANTLR's rewrite syntax using a caret (i.e. ^(ROOT child...)), gunit matches trees without the caret, so the above represents a tree and it's not surprising that it fails: it's a flat list of nodes and not a tree. This results in a test failure: 1 failures found: test2 (objectOption walks objectOption, line17) - expected: (one \"value\") actual: one \"value\" Another option which seems intuitive is to leave off the parenthesis, like this: objectOption walks objectOption: <<one:"value">> -> one "value" But gunit doesn't like this syntax. It seems to result in a parse failure in the gunit grammar: line 17:20 no viable alternative at input 'one' line 17:24 missing ':' at 'value' line 0:-1 no viable alternative at input '<EOF>' java.lang.NullPointerException at org.antlr.gunit.OutputTest.getExpected(OutputTest.java:65) at org.antlr.gunit.gUnitExecutor.executeTests(gUnitExecutor.java:245) ... What is the correct way to match a flat tree?
