• MVVM/Presentation Model With WinForms

  - by Erik Ashepa

  Hi, I'm currently working on a brownfield application, it's written with winforms, as a preparation to use WPF in a later version, out team plans to at least use the MVVM/Presentation model, and bind it against winforms... I've explored the subject, including the posts in this site (which i love very much), when boiled down, the main advantage of wpf are : binding controls to properties in xaml. binding commands to command objects in the viewmodel. the first feature is easy to implement (in code), or with a generic control binder, which binds all the controls in the form. the second feature is a little harder to implement, but if you inherit from all your controls and add a command property (which is triggered by an internal event such as click), which is binded to a command instance in the ViewModel. The challenges I'm currently aware of are : implementing a commandmanager, (which will trigger the CanInvoke method of the commands as necessery. winforms only supports one level of databinding : datasource, datamember, wpf is much more flexible. am i missing any other major features that winforms lacks in comparison with wpf, when attempting to implement this design pattern? i sure many of you will recommend some sort of MVP pattern, but MVVM/Presentation model is the way to go for me, because I'll want future WPF support. Thanks in advance, Erik.

• SharePoint: You cannot grant limited access permission level

  - by chiccodoro

  In my team, we implemented some UI to set user access rights (assign/revoke permission levels) on a certain SharePoint list. The UI supplies a "undo" feature: If you change the rights over the UI, you can restore the rights the user had before by clicking "undo". Now there is a problem if the user had the "Limited Access" permission level: This permission level is removed when you do a change over the UI. When trying to Undo, the permission level should be added again, which leads to a You cannot grant a user the limited access permission level. I've read that SharePoint grants that right automatically when a user gets access to some entity beneath the site. Still I can revoke the right manually, but then I cannot re-grant it. Is there a proper way I could work around that? My thoughts: Did I get it right that this "limited access" is granted by SharePoint on the site level only? So, do all the lists beneath the site only contain that permission level "accidentally" because they inherit it? Does that permission level have any effect at all on a list, or does it only apply to the site itself? So, would it be save to just remove it from a list and do not add it anymore when the user clicks "undo", since it has no effect anyway? (My UI always works on list / list item level, never on the whole site/web).

• 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.

• DynamicObject and WCF support

  - by rboarman

  Hi, I was wondering if anyone has had any luck getting a DynamicObject to serialize and work with WCF? Here’s my little test: [DataContract] class MyDynamicObject : DynamicObject { [DataMember] private Dictionary<string, object> _attributes = new Dictionary<string, object>(); public override bool TryGetMember(GetMemberBinder binder, out object result) { string key = binder.Name; result = null; if (_attributes.ContainsKey(key)) result = _attributes[key]; return true; } public override bool TrySetMember(SetMemberBinder binder, object value) { _attributes.Add(binder.Name, value); return true; } } var dy = new MyDynamicObject(); var ser = new DataContractSerializer(typeof(MyDynamicObject)); var mem = new MemoryStream(); ser.WriteObject(mem, dy); The error I get is: System.Runtime.Serialization.InvalidDataContractException was unhandled Message=Type 'ElasticTest1.MyDynamicObject' cannot inherit from a type that is not marked with DataContractAttribute or SerializableAttribute. Consider marking the base type 'System.Dynamic.DynamicObject' with DataContractAttribute or SerializableAttribute, or removing them from the derived type. Any suggestions? Thanks, Rick

• asp.net mvc2 - controller for master page?

  - by ile

  I've just finished my first ASP.NET MVC (2) CMS. Next step is to build website that will show data from CMS's database. This is website design: #1 (Red box) - displays article categories. ViewModel: public class CategoriesDisplay { public CategoriesDisplay() { } public int CategoryID { set; get; } public string CategoryTitle { set; get; } } #2 (Brown box) - displays last x articles; skips those from green box #3. Viewmodel: public class ArticleDisplay { public ArticleDisplay() { } public int CategoryID { set; get; } public string CategoryTitle { set; get; } public int ArticleID { set; get; } public string ArticleTitle { set; get; } public string URLArticleTitle { set; get; } public DateTime ArticleDate; public string ArticleContent { set; get; } } #3 (green box) - Displays last x articles. Uses the same ViewModel as brown box #2 #4 (blue box) - Displays list of upcoming events. Uses dataContext.Model.Event as ViewModel Boxes #1, #2 and #4 will repeat all over the site and they are part of Master Page. So, my question is: what is the best way to transfer this data from Model to Controller and finally to View pages? Should I make a controller for master page and ViewModel class that will wrap all this classes together OR Should I create partial Views for every of these boxes and make each of them inherit appropriate class (if it is even possible that it works this way?) OR Should I put this repeated code in all controllers and all additional data transfer via ViewData, which would be probably the worse way :) OR There is maybe a better and more simple way but I don't know/see it? Thanks in advance, Ile

• OO Design - polymorphism - how to design for handing streams of different file types

  - by Kache4

  I've little experience with advanced OO practices, and I want to design this properly as an exercise. I'm thinking of implementing the following, and I'm asking if I'm going about this the right way. I have a class PImage that holds the raw data and some information I need for an image file. Its header is currently something like this: #include <boost/filesytem.hpp> #include <vector> namespace fs = boost::filesystem; class PImage { public: PImage(const fs::path& path, const unsigned char* buffer, int bufferLen); const vector<char> data() const { return data_; } const char* rawData() const { return &data_[0]; } /*** other assorted accessors ***/ private: fs::path path_; int width_; int height_; int filesize_; vector<char> data_; } I want to fill the width_ and height_ by looking through the file's header. The trivial/inelegant solution would be to have a lot of messy control flow that identifies the type of image file (.gif, .jpg, .png, etc) and then parse the header accordingly. Instead of using vector<char> data_, I was thinking of having PImage use a class, RawImageStream data_ that inherits from vector<char>. Each type of file I plan to support would then inherit from RawImageStream, e.g. RawGifStream, RawPngStream. Each RawXYZStream would encapsulate the respective header-parsing functions, and PImage would only have to do something like height_ = data_.getHeight();. Am I thinking this through correctly? How would I create the proper RawImageStream subclass for data_ to be in the PImage ctor? Is this where I could use an object factory? Anything I'm forgetting?

• VB .NET DirectCast and Type Reflection

  - by msarchet

  The application that I am working on has a generic Parent Form called RSChild, that is used to perform some operations depending on whether or not the control that is contained within it is in a MdiTabManager or inside of its own modal form. Then the actual User Controls contained within Inherit from a Interface Called ObjectEdit (Objects that we allow to be edited). At a point in my code I am doing this. Public Function doesTabExist(ByVal id As Integer, ByVal recordType As Enums.eRecordType) As Boolean Dim alikePages As Object = (From tabs In DirectCast(Control.FromHandle(MainForm.SharedHandle), MainForm).XtraTabbedMdiManager1.Pages Where DirectCast(tabs.MdiChild, RSChild).RSObject.RecordType = recordType Select tabs) For Each page As DevExpress.XtraTabbedMdi.XtraMdiTabPage In alikePages Select Case recordType Case Enums.eRecordType.Doctor If id = DirectCast(castTabPageToRSChild(page).RSObject, UI.Doctor).ID Then pageToActive(page) Return True End If 'rest of the cases so the case block is repeated 10 times' End Function And my castTabPageToRSChild(page) is a lambda function as Such Dim castTabPageToRSChild As Func(Of DevExpress.XtraTabbedMdi.XtraMdiTabPage, RSChild) = Function(page) DirectCast(page.MdiChild, RSChild) So my Question is, I have about 10 case statements, all because I can't seem to find a way to use reflection to get the underlying Type of the RSObject Object. So I have the whole If block repeated over and over. I tried doing castTabPageToRSChild(page)RSObject.GetType and using that in the DirectCast and I also tried creating another object that was separate from that and doing the same thing. My code works as intended I'm just trying to see if there is a manner in which I didn't have a lot of replicated code. My vision would be to do something like For Each page As XtraMdiTabPage In alikePages If id = DirectCast(castTabPageToRSchild(page).RSObject, TypeOfThatObject).Id Then Return True Next However I have a feeling this is not possible due to the behavior of DirectCast.

• How can I programmatically link an UIView or UIImageView with an event like "touch up inside"?

  - by Thanks

  Interface Builder will only allow me to hook up such events for an button. But like in HTML, I just want to haven an blank UIImageView where - as soon as the user taps it - a method is invoked. I hope there is some cool programmatically way of doing that, which I don't know about. UPDATE: In my View Controller that creates the UIImageView I tried to do this: SEL actionSelector = @selector(doSomethingWhenImageIsTouched:); [self.myUIImageView addTarget:nil action:actionSelector forControlEvents:UIControlEventTouchUpInside]; The compiler gives me a warning, that UIImageView may not respond to addTarget:... what do I have to do so that it works with an UIImageView. I see in the docs that UIImageView does not inherit from UIControl, but addTarget: is part of UIControl. UPDATE: I ended up creating an UIButton after creating the UIImageView. Then I set the frame of that button to the frame of the UIImageView, and alpha to 0.1f. For some reason, it will not work if alpha is 0.0f. And then, I did that cool addTarget: thing...

• Jeditable Datepicker onblur problem

  - by Shobha Deepthi

  Hi, I am using inline editing using Jeditable and datepicker. I have a column in my table which displays Date as a hyperlink. When I click on this it shows me the datepicker. And when a particular date is selected its updated in the backend and the cell now is updated with the changed value. However, am having problem with onblur event while changing month or years. This event gets triggered when I click on "Prev" or "Next" buttons on the datepicker control. This causes an exception when the date is selected. This works fine as long as the date selected is in the current month. I tried all possible solutions listed here: stackoverflow.com/questions/2007205/jeditable-datepicker-causing-blur-when-changing-month If settimeout the control does not change back to a normal hyperlink on closing the datepicker or on a true onblur event. Here's my code, $.editable.addInputType('datepicker', { element : function(settings, original) { var input = $(''); if (settings.width != 'none') { input.width(settings.width); } if (settings.height != 'none') { input.height(settings.height); } input.attr('autocomplete','off'); $(this).append(input); return(input); }, plugin : function(settings, original) { var form = this; settings.onblur = function(e) { t = setTimeout(function() { original.reset.apply(form, [settings, self]); }, 100); }; $(this).find('input').datepicker({ changeMonth: true, changeYear: true, dateFormat: 'dd-M-y', closeAtTop: true, onSelect: function(dateText) { $(this).hide(); $(form).trigger('submit'); } }); }, submit : function(settings, original) { } }); $(function() { $('.edit_eta').editable('update_must_fix_eta.php', { id: 'bugid', name: 'eta', type: 'datepicker', event: 'click', select : true, width: '50px', onblur:'cancel', cssclass : 'editable', indicator : 'Updating ETA, please wait.', style : 'inherit', submitdata:{version:'4.2(4)',tag:'REL_4_2_4',qstr:1} }); }); I tried hacking jeditable.js as mentioned on this link: http://groups.google.com/group/jquery-dev/browse_thread/thread/265340ea692a2f47 Even this does not help. Any help is appreciated.

• Javadoc through Ant task with {@inheritDoc} from J2SE classes

  - by miorel

  I generate documentation for a project using an Ant task. In several places, I wanted to inherit documentation from the standard classes, so I used {@inheritDoc} which allowed me to see the Javadoc in Eclipse, but it wouldn't show up in the HTML files. The problem was that I hadn't included the unzipped src.zip (J2SE source) in the sourcepath. Having fixed that, I now get several hundred warnings about the use of Sun proprietary API in files like lib/jdk-src/java/lang/Class.java. Is there any way to suppress these warnings? It's hard to find relevant problems in this mess. A possible solution I thought of was to run the Javadoc task once without including the J2SE source in the sourcepath, which will reveal any real issues. Then I can run Javadoc a second time with the J2SE source included, discarding the output altogether, which will produce documentation with properly-working {@inheritDoc}s. I'm not entirely sure about the best way to accomplish this in Ant, not to mention that running Javadoc twice would be a dirty fix. Any suggestions?

• How to extend an 'unloadable' Rails plugin?

  - by Vitaly Kushner

  I'm trying to write a plugin that will extend InheritedResources. Specifically I want to rewrite some default helpers. And I'd like it to "just work" once installed, w/o any changes to application code. The functionality is provided in a module which needs to be included in a right place. The question is where? :) The first attempt was to do it in my plugin's init.rb: InheritedResources::Base.send :include, MyModule It works in production, but fails miserably in development since InheritedResource::Base declared as unloadable and so its code is reloaded on each request. So my module is there for the first request, and then its gone. InheritedResource::Base is 'pulled' in again by any controller that uses it: Class SomeController < InheritedResource::Base But no code is 'pulling in' my extension module since it is not referenced anywhere except init.rb which is not re-loaded on each request So right now I'm just including the module manually in every controller that needs it which sucks. I can't even include it once in ApplicationController because InheritedResources inherites from it and so it will override any changes back. update I'm not looking for advice on how to 'monkey patch'. The extension is working in production just great. my problem is how to catch moment exactly after InheritedResources loaded to stick my extension into it :) update2 another attempt at clarification: the sequence of events is a) rails loads plugins. my plugin loads after inherited_resources and patches it. b) a development mode request is served and works c) rails unloads all the 'unloadable' code which includes all application code and also inherited_resources d) another request comes in e) rails loads controller, which inherites from inherited resources f) rails loads inherited resources which inherit from application_controller g) rails loads application_contrller (or may be its already loaded at this stage, not sure) g) request fails as no-one loaded my plugin to patch inherited_resources. plugin init.rb files are not reloaded I need to catch the point in time between g and h

• cannot convert 'b2PolygonShape' to 'objc_object*' in argument passing

  - by GONeale

  Hey there, I am not sure if many of you are familiar with the box2d physics engine, but I am using it within cocos2d and objective c. This more or less could be a general objective-c question though, I am performing this: NSMutableArray *allShapes = [[NSMutableArray array] retain]; b2PolygonShape shape; .. .. [allShapes addObject:shape]; and receiving this error on the addObject definition on build: cannot convert 'b2PolygonShape' to 'objc_object*' in argument passing So more or less I guess I want to know how to add a b2PolygonShape to a mutable array. b2PolygonShape appears to just be a class, not a struct or anything like that. The closest thing I could find on google to which I think could do this is described as 'encapsulating the b2PolygonShape as an NSObject and then add that to the array', but not sure the best way to do this, however I would have thought this object should add using addObject, as some of my other instantiated class objects add to arrays fine. Is this all because b2PolygonShape does not inherit NSObject at it's root? Thanks

• Inheriting from ViewPage forces explicit casting of model in view

  - by Martin Hansen

  I try to inhering from ViewPage as shown in this question http://stackoverflow.com/questions/370500/inheriting-from-viewpage But I get a Compiler Error Message: CS1061: 'object' does not contain a definition for 'Spot' and no extension method 'Spot' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) My viewpage, normally I can do Model.ChildProperty(Spot) when I inherit from ViewPage directly, so I do that here too. But it fails. <%@ Page Language="C#" Inherits="Company.Site.ViewPageBase<WebSite.Models.SpotEntity>" %> <h1><%= Html.Encode(Model.Spot.Title) %></h1> To get it working correctly I have to do like this: <%@ Page Language="C#" Inherits="Company.Site.ViewPageBase<WebSite.Models.SpotEntity>" %> <h1><%= Html.Encode(((WebSite.Models.SpotEntity)Model).Spot.Title) %></h1> Here is my classes: namespace Company.Site { public class ViewPageBase<TModel> : Company.Site.ViewPageBase where TModel:class { private ViewDataDictionary<TModel> _viewData; [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")] public new ViewDataDictionary<TModel> ViewData { get { if (_viewData == null) { SetViewData(new ViewDataDictionary<TModel>()); } return _viewData; } set { SetViewData(value); } } protected override void SetViewData(ViewDataDictionary viewData) { _viewData = new ViewDataDictionary<TModel>(viewData); base.SetViewData(_viewData); } } public class ViewPageBase : System.Web.Mvc.ViewPage { } } So how do I get it to work without the explicit cast?

• QTcpServer not emiting signals

  - by Timothy Baldridge

  Okay, I'm sure this is simple, but I'm not seeing it: HTTPServer::HTTPServer(QObject *parent) : QTcpServer(parent) { connect(this, SIGNAL(newConnection()), this, SLOT(acceptConnection())); } void HTTPServer::acceptConnection() { qDebug() << "Got Connection"; QTcpSocket *clientconnection = this->nextPendingConnection(); connect(clientconnection, SIGNAL(disconnected()), clientconnection, SLOT(deleteLater())); HttpRequest *req = new HttpRequest(clientconnection, this); req->processHeaders(); delete req; } int main(int argc, char *argv[]) { QCoreApplication a(argc, argv); HTTPServer http(0); http.listen(QHostAddress::Any, 8011); qDebug() << "Started: " << http.isListening() << http.serverAddress() << ":" << http.serverPort(); return a.exec(); } According to the docs my acceptConnection() slot should be called whenever there is a new connection. I can connect into this tcp port with a browser or telnet, and I don't get any errors, so I know it's listening, execution never goes to my acceptConnection() function? And yes my objects inherit from QObject, I've just stripped the code down to the essential parts above. There's no build errors....

• Progress Bar design patterns?

  - by shoosh

  The application I'm writing performs a length algorithm which usually takes a few minutes to finish. During this time I'd like to show the user a progress bar which indicates how much of the algorithm is done as precisely as possible. The algorithm is divided into several steps, each with its own typical timing. For instance- initialization (500 milli-sec) reading inputs (5 sec) step 1 (30 sec) step 2 (3 minutes) writing outputs (7 sec) shutting down (10 milli-sec) Each step can report its progress quite easily by setting the range its working on, say [0 to 150] and then reporting the value it completed in its main loop. What I currently have set up is a scheme of nested progress monitors which form a sort of implicit tree of progress reporting. All progress monitors inherit from an interface IProgressMonitor: class IProgressMonitor { public: void setRange(int from, int to) = 0; void setValue(int v) = 0; }; The root of the tree is the ProgressMonitor which is connected to the actual GUI interface: class GUIBarProgressMonitor : public IProgressMonitor { GUIBarProgressMonitor(ProgressBarWidget *); }; Any other node in the tree are monitors which take control of a piece of the parent progress: class SubProgressMonitor : public IProgressMonitor { SubProgressMonitor(IProgressMonitor *parent, int parentFrom, int parentLength) ... }; A SubProgressMonitor takes control of the range [parentFrom, parentFrom+parentLength] of its parent. With this scheme I am able to statically divide the top level progress according to the expected relative portion of each step in the global timing. Each step can then be further subdivided into pieces etc' The main disadvantage of this is that the division is static and it gets painful to make changes according to variables which are discovered at run time. So the question: are there any known design patterns for progress monitoring which solve this issue?

• How to reset parent child relationship between nested div

• dximagetransform.matrix, absolutely position child elements not rotating in IE 8 standards mode

  - by davydka

  I've looked all over for more information on this, and would like to know why it happens. Here's the code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> </head> <body> <div style="position:absolute; top:200px; left:200px; height:200px; width:200px; border:1px solid black; filter: progid:DXImageTransform.Microsoft.Matrix(sizingMethod='auto expand', M11=0.9886188373396114, M12=-0.15044199698646263, M21=0.15044199698646263, M22=0.9886188373396114);"> <div style="position:absolute; top:10px; left:10px; border:1px solid darkblue;"> I do not rotate in IE 8. </div> </div> </body> </html> The problem is that absolutely or relatively positioned elements within a div that has been rotated using MS's dximagetransform.matrix do not inherit the transformation in IE 8. IE 6 & 7 render correctly, and I can solve the IE8 problem by triggering compatibility mode, but I'd rather not do that. Does anyone have any experience with this? I'm using css3 transform on other browsers and using dximagetransform.matrix to achieve this effect in IE. EDIT: Added the opening html tag. Problem still exists. http://i45.tinypic.com/nf4gmq.png

• FindByIdentity in System.DirectoryServices.AccountManagment Memory Issues

  - by MVC Fanatic

  I'm working on an active directory managament application. In addition to the typical Create A New User, Enable/Disable an account, reset my password etc. it also managages application permissions for all of the clients web applications. Application management is handled by thousands of AD groups such as which are built from 3 letter codes for the application, section and site, there are also hundreds of AD groups which determine which applications and locations a coordinator can grant rights to. All of these groups in turn belong to other groups so I typically filter the groups list with the MemberOf property to find the groups that a user directly belongs to (or everyone has rights to do everything). I've made extensive use of the System.DirectoryServices.AccountManagment namespace using the FindByIdentity method in 31 places throughout the application. This method calls a private method FindPrincipalByIdentRefHelper on the internal ADStoreCtx class. A SearchResultCollection is created but not disposed so eventually typically once or twice a day the web server runs out of memory and all of the applications on the web server stop responsing until iis is reset because the resources used by the com objects aren't ever relased. There are places where I fall back to the underlying directory objects, but there are lot of places where I'm using the properties on the Principal - it's a vast improvement over using the esoteric ad property names in the .Net 2.0 Directory services code. I've contacted microsoft about the problem and it's been fixed in .Net 4.0 but they don't currently have plans to fix it in 3.5 unless there is intrest in the community about it. I only found information about it in a couple of places the MDSN documentation in the community content state's there is a memory leak at the bottom (guess I should have read that before using the the method) http://msdn.microsoft.com/en-us/library/bb345628.aspx And the class in question is internal and doesn't expose SearchResultsCollection outside the offending method so I can't get at the results to dispose them or inherit from the class and override the method. So my questions are Has anyone else encountered this problem? If so were you able to work around it? Do I have any option besides rewriting the application not using any of the .Net 3.5 active directory code? Thanks

• How to determine if a ResourceDictionary is loaded correctly

  - by akaphenom

  How can I tell (through the debugger if my app resources are being loaded correctly). I have tried (in f#) type MyApp() as this = inherit Application() do Application.LoadComponent(this, new System.Uri("/FSSilverlightApp;component/App.xaml", System.UriKind.Relative)) let cc = new ContentControl() let mainGrid : Grid = loadXaml("MainWindow.xaml") let siteTemplate : Grid = mainGrid let txt : TextBlock = siteTemplate ? txt do this.Startup.Add(this.startup) let mutable s = "Items: " s <- s + this.Resources.Count.ToString() it is returning a count of zero. Though I am pretty sure the application is loading the resource because if I change the path within the App.xaml - I get exceptions at runtime. Other re,lavent snippets are: I have the following app.xaml <Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Module1.MyApp"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/FSSilverlightApp;component/TransitioningFrame.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> and content template: < ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ControlTemplate x:Key="TransitioningFrame" TargetType="navigation:Frame"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <ContentPresenter Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="{TemplateBinding Content}"/> </Border> </ControlTemplate> </ResourceDictionary>

• Why is Assembly.GetCustomAttributes suddenly throwing TypeLoadException on build machine with Silver

  - by andrej351

  A short while back i had to display the current version of our Silverlight app. After some googling the following code gave me the desired result: var fileVersionAttributes = typeof(MyClass).Assembly. GetCustomAttributes(typeof(AssemblyFileVersionAttribute), false) as AssemblyFileVersionAttribute[]; var version = fileVersionAttributes[0].Version; This worked a treat in our .NET 3.5 Silverlight 3 environment. However, we recently upgraded to .NET 4 and Silverlight 4. We just finished getting our build machine working and found that the unit test for this code was throwing the following exception: Exception Message: System.TypeLoadException: Error 0x80131522. Debugging resource strings are unavailable. See http://go.microsoft.com/fwlink/?linkid=106663&Version=3.0.50106.0&File=mscorrc.dll&Key=0x80131522 at System.ModuleHandle.ResolveType(ModuleHandle module, Int32 typeToken, RuntimeTypeHandle* typeInstArgs, Int32 typeInstCount, RuntimeTypeHandle* methodInstArgs, Int32 methodInstCount) at System.ModuleHandle.ResolveTypeHandle(Int32 typeToken, RuntimeTypeHandle[] typeInstantiationContext, RuntimeTypeHandle[] methodInstantiationContext) at System.Reflection.Module.ResolveType(Int32 metadataToken, Type[] genericTypeArguments, Type[] genericMethodArguments) at System.Reflection.CustomAttribute.FilterCustomAttributeRecord(CustomAttributeRecord caRecord, MetadataImport scope, Assembly& lastAptcaOkAssembly, Module decoratedModule, MetadataToken decoratedToken, RuntimeType attributeFilterType, Boolean mustBeInheritable, Object[] attributes, IList derivedAttributes, RuntimeType& attributeType, RuntimeMethodHandle& ctor, Boolean& ctorHasParameters, Boolean& isVarArg) at System.Reflection.CustomAttribute.GetCustomAttributes(Module decoratedModule, Int32 decoratedMetadataToken, Int32 pcaCount, RuntimeType attributeFilterType, Boolean mustBeInheritable, IList derivedAttributes, Boolean isDecoratedTargetSecurityTransparent) at System.Reflection.CustomAttribute.GetCustomAttributes(Module decoratedModule, Int32 decoratedMetadataToken, Int32 pcaCount, RuntimeType attributeFilterType, Boolean isDecoratedTargetSecurityTransparent) at System.Reflection.CustomAttribute.GetCustomAttributes(Assembly assembly, Type caType) at System.Reflection.Assembly.GetCustomAttributes(Type attributeType, Boolean inherit) at MyCode.VersionTest() I have never seen this exception before and the link in it points nowhere. It is only throwing on the build machine and not on my development box, so i'm going through a process of trial and error to see any differences between the two. Any idea why this might be happening?? Cheers, Andrej.

• Code required to use foreach on my own custom appSettings

  - by jamauss

  I've searched the site and haven't found exactly what I'm looking for. Close, but no cigar. Basically I want to have a config section like this: <configSections> <section name="PhoneNotificationsSection" type="Alerts.PhoneAlertConfigSection,Alerts,Version=1.0.0.0,Culture=neutral,PublicKeyToken=null"/> </configSections> <PhoneNotificationsSection> <phones> <add phone="MyMobile" value="[email protected]" /> <add phone="OtherMobile" value="[email protected]" /> </phones> </PhoneNotificationsSection> Then I'd like to, in my appSettings consuming code, be able to write something like this (pseudo code): foreach (phone p in phones) { //'phone' attribute is just helpful/descriptive DoSomething(p.value); } I've done enough research to know I probably need a few of my own classes that implement and/or inherit from certain Configuration classes to make the above code possible. I just haven't found anything that clearly demonstrates this scenario and how to code for it - and when I try to learn the whole .NET configuration world my brain starts to hurt. Anyone have some code like what I'm looking for that they can share?

• CSS - Inheriting layered background images

  - by NNN

  CSS3 supports multiple background images, for example: foo { background-image: url(/i/image1.jpg), url(/i/image2.jpg); } I'd like to be able to add a secondary image to an element with a class though. So for example, say you have a nav menu. And each item has a background image. When a nav item is selected you want to layer on another background image. I do not see a way to 'add' a background image instead of redeclaring the whole background property. This is a pain because in order to do this with multi-backgrounds, you would have to write the base bg image over and over for each item if the items have unique images. Ideally I'd be able to do something like this: li { background: url(baseImage.jpg); } li.selected { background: url(selectedIndicator.jpg); } And have li.selected's end result appear the same if I did: li.selected { background: url(baseImage.jpg), url(selectedIndicator.jpg); } Update: I also tried the following with no luck (I believe backgrounds are not inherited..) li { background: url(baseImage.jpg), none; } li.selected { background: inherit, url(selectedIndicator.jpg); }

• How to use Object.GetHashCode() on a type that overrides GetHashCode()

  - by Jimmy

  Hi, I have a class A that implements IEquatable<, using its fields (say, A.b and A.c) for implementing/overriding Equals() and overriding GetHashCode(), and everything works fine, 99% of the time. Class A is part of a hierarchy (class B, C) that all inherit from interface D; they can all be stored together in a dictionary Dictionary, thus it's convenient when they all carry their own default Equals()/GetHashCode(). However, while constructing A I sometime need to do some work to get the values for A.b and A.c; while that's happening, I want to store a reference to the instance that's being built. In that case, I don't want to use the default Equals()/GetHashCode() overrides provided by A. Thus, I was thinking of implementing a ReferenceEqualityComparer, that's meant to force the use of Object's Equals()/GetHashCode(): private class ReferenceEqualityComparer<T> : IEqualityComparer<T> { #region IEqualityComparer<T> Members public bool Equals(T x, T y) { return System.Object.ReferenceEquals(x, y); } public int GetHashCode(T obj) { // what goes here? I want to do something like System.Object.GetHashCode(obj); } #endregion } The question is, since A overrides Object.GetHashCode(), how can I (outside of A) call Object.GetHashCode() for an instance of A? One way of course would be for A to not implement IEquatable< and always supply an IEqualityComparer< to any dictionary that I create, but I'm hoping for a different answer. Thanks

• Use any CSS compiler (Sass, Less) to generate the selector

  - by xckpd7

  So I've recently been playing around with CSS compilers, but I have no idea how (or if it's possible) to dynamically generate pieces of a selector. For instance, let's say I wanted to make mixins to get display: inline-block; to work cross browser. I would have to do the styles, yeah, but I would have to do the IE6/7 selector hacks to get them to work in those browsers too. Ideally I'm looking for a one off thing to add to an element and have the ability for that to work. Some kind person recently gave me this solution: http://stackoverflow.com/questions/2746754/css-compilers-and-converting-ie-hacks-to-conditional-css/2747036#2747036 and it would be nice to implement that in a minimal way that would allow me to specify it for a given element and be on my way (for instance in Less, you can create a class with styles, pass that class to another element, and that element will inherit all of those styles. It would be nice to pass an element .inline-block; and it create the styles needed to support IE6/7 without having to resort to stuff like _color: pink; Any ideas? EDIT: for instance as well, how could I do something like clearfix for LESS? (lesscss.org)? If Sass can only do it then that will work too.

• pushViewController Not Displaying UIView/Nib with tabbar and nav bar

  - by james

  I'm relatively new to objective c but not programming and am stuck with my iphone app. I created a nav based app with both a navbar and a tab bar controller. I set the tab bar as the root controller. I'm able to switch between each tab without any issues to various UIViews and UITableViews. My issue is that in one of my UITableViews that I call from the TabBarController, didSelectRowAtIndexPath function is suppose to display a new UIView. The below code does not give any errors and runs fine but does not show the new Nib. if(newViewController == nil) { NSLog(@"yes nil"); BookViewController *aNewViewController = [[BookViewController alloc] initWithNibName:@"BookOptionView" bundle:nil]; self.newViewController = aNewViewController; [aNewViewController release]; } BookAppDelegate *delegate = (BookAppDelegate *)[[UIApplication sharedApplication] delegate]; [delegate.appNavBar pushViewController:newViewController animated:YES]; Now when I do the below, it works fine but it gets rid of the nav and tab which I'm assuming because its a modal call instead of pushing the view controller. BookViewController *screen = [[BookViewController alloc] initWithNibName:@"BookOptionView" bundle:[NSBundle mainBundle]]; screen.modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self presentModalViewController:screen animated:YES]; [screen release]; Any ideas why I can't get the View Controller to push correctly? In my application delegate file, I declared an AppNavBarController object (inherit from UINavigationController) called appNavBar. Any help would be appreciated!
