• MonoTouch: using embedded resx files on iPhone build

  - by bright

  I'm able to load and access resx files in Simulator builds of my iPhone app built using MonoTouch. The resx file entry in the csproj file looks like: <ItemGroup> <EmbeddedResource Include="MapMenu\Resources\MapMenu.resx"> <Generator>ResXFileCodeGenerator</Generator> <LastGenOutput>MapMenu.Designer.cs</LastGenOutput> </EmbeddedResource> </ItemGroup> The .resx file itself has an entry like this: <data name="Main_Menu" type="System.Resources.ResXFileRef, System.Windows.Forms"> <value>Main Menu.mm;System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089;Windows-1252</value> </data> and the generated MapMenu.Designer.cs file has this: internal static string Main_Menu { get { return ResourceManager.GetString("Main_Menu", resourceCulture); } } As mentioned above, calling the Main_Menu accessor works fine on the simulator. On the device, however, it produces: <Notice>: Unhandled Exception: System.MissingMethodException: No constructor found for System.Resources.RuntimeResourceSet::.ctor(System.IO.UnmanagedMemoryStream) <Notice>: at System.Activator.CreateInstance (System.Type type, BindingFlags bindingAttr, System.Reflection.Binder binder, System.Object[] args, System.Globalization.CultureInfo culture, System.Object[] activationAttributes) [0x00000] in <filename unknown>:0 <Notice>: at System.Activator.CreateInstance (System.Type type, System.Object[] args, System.Object[] activationAttributes) [0x00000] in <filename unknown>:0 <Notice>: at System.Activator.CreateInstance (System.Type type, System.Object[] args) [0x00000] in <filename unknown>:0 <Notice>: at System.Resources.ResourceManager.InternalGetResourceSet (System.Globalization.CultureInfo culture, Boolean createIfNotExists, Boolean tryParents) [0x00000] in <filename unknown>:0 <Notice>: at System.Resources.ResourceManager.GetString (System.String name, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0 <Notice>: at MapMenu.Resources.MapMenu.get_Main_Menu () [0x00000] in <filename unknown>:0 Did a few sanity checks, and am wondering at this point if this really is missing functionality in Monotouch. Thanks,

• MVVM Binding Selected RadOutlookBarItem

  - by Christian

  Imagine: [RadOutlookBarItem1] [RadOutlookBarItem2] [RadOutlookBar] [CONTENCONTROL] What i want to achieve is: User selects one of the RadOutlookBarItem's. Item's tag is bound like: Tag="{Binding SelectedControl, Mode=TwoWay}" MVVM Property public string SelectedControl { get { return _showControl; } set { _showControl = value; OnNotifyPropertyChanged("ShowControl"); } } ContentControl has multiple CustomControls and Visibility of those is bound like: <UserControl.Resources> <Converters:BoolVisibilityConverter x:Key="BoolViz"/> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White"> <Views:ViewDocumentSearchControl Visibility="{Binding SelectedControl, Converter={StaticResource BoolViz}, ConverterParameter='viewDocumentSearchControl'}"/> <Views:ViewStartControl Visibility="{Binding SelectedControl, Converter={StaticResource BoolViz}, ConverterParameter='viewStartControl'}"/> </Grid> Converter: public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { // here comes the logic part... should return Visibility.Collapsed : Visibility.Visible based on 'object value' value System.Diagnostics.Debugger.Break(); return Visibility.Collapsed; } now, logically the object value is always set to null. So here's it comes to my question: How can i put a value into the SelectedControl Variable for the RadOutlookBarItem's Tag. I mean something like Tag="{Binding SelectedControl, Mode=TwoWay, VALUE='i.e.ControlName'"} So that i can decide, using the Convert Method, whether a specific Control's visibility is either set to collapsed or visible? help's appreciated Christian

• hibernate and ehcache replication

  - by cachingsol

  Hi, I am working on a cache replication solution between nodes Node A - master node = Hibernate + Database + Ehcache as secondary cache Node B - regional node= Ehcache as prmiary cache. no Hibernate Node B is used only as near-by cache for query. Now I am updating data (Say SudentInfo) in Node A, it gets persisted and cached correctly. On replication side (I am using JMS) it sends a message to Node B. But the problem is, the message it sends is of instance CacheEntry(deep Inside Element), there is no way to resurrect the original object (StudentInfo). What I got in node B is CacheEntry with some attributes of Students but not actually an Student Object. Please note that I don't need Hibernate session/persistence in Node B, node B is only for fast query, persistence is done through Node A. So has anybody tried any solution like this? Is there any way to convert CacheEntry to actual object? or Tell ehcache to replicate original object rather than CacheEntry. Thanks for the help

• Webservice returns java.lang.reflect.InvocationTargetException

  - by Damian

  Hi, I am receiving the above message when making a request to a java webservice. We originally created a Java Console application and manually submitted an xml file. When running this as a Java Application the response is successfully created and displayed by using System.out.println. We are creating the web service by selecting the java file that contains the methods and choosing "create webservice" specifying the dynamic project that the webservice is to be created in and the methods to be exposed. What the application is doing is taking an xml file and unmarshalling this to an object using: public static Object unmarshalToObject(Class classToBeBound, String xmlRequest) { Object obj = new Object(); try { JAXBContext jc = JAXBContext.newInstance(classToBeBound); Unmarshaller um = jc.createUnmarshaller(); obj = um.unmarshal(new StringReader(xmlRequest)); } catch (Exception e) { e.printStackTrace() } return obj; } Some processing is carried out on the file and then an object is marshalled to xml as follows: public static String marshalToXML(Object data) { StringWriter sw = new StringWriter(); try { logger.info("Create new Marshall"); JAXBContext jc = JAXBContext.newInstance("ContextPathName"); logger.info("Marshalled to xmlObjects"); Marshaller marshaller = jc.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true); marshaller.marshal(data, sw); } catch (Exception e) { logException(logger, e); } return sw.toString(); } The following is the line of code that seems to be causing an issue as the logger displays the message prior to this: JAXBContext jc = JAXBContext.newInstance("ContextPathName"); The webservice never gets to the next line - the following is the body of the SOAP message: <soapenv:Fault> <faultcode>soapenv:Server.userException</faultcode> <faultstring>java.lang.reflect.InvocationTargetException</faultstring> <detail> <ns1:hostname xmlns:ns1="http://xml.apache.org/axis/">servername</ns1:hostname> </detail> </soapenv:Fault> I have added Try/Catch around this section of code even as far as looking for JAXBExceptions but this does not seem to catch anything - nor does the general exception. This issue does not occur when running the console application. The build path for this includes the following contents of sun\jwsdp-2.0\jaxb\lib: jaxb-api.jar jsr173_1.0_api.jar jaxb-impl.jar I have added these to the lib folder in the WEB-INF file of the dynamic project. I am running the webservice in JBuilder 2008 R2 and using SOAPUI to submit the request - this points to the wsdl generated when creating the webservice. If anyone has any help or ideas on how to solve this could they please reply - thanks for taking the time to read this post!

• iPhone Key-Value Observer: observer not registering in UITableViewController

  - by Scott

  Hi Fellow iPhone Developers, I am an experienced software engineer but new to the iPhone platform. I have successfully implemented sub-classed view controllers and can push and pop parent/child views on the view controller stack. However, I have struck trouble while trying to update a view controller when an object is edited in a child view controller. After much failed experimentation, I discovered the key-value observer API which looked like the perfect way to do this. I then registered an observer in my main/parent view controller, and in the observer I intend to reload the view. The idea is that when the object is edited in the child view controller, this will be fired. However, I think that the observer is not being registered, because I know that the value is being updated in the editing view controller (I can see it in the debugger), but the observing method is never being called. Please help! Code snippets follow below. Object being observed. I believe that this is key-value compliant as the value is set when called with the setvalue message (see Child View Controller below). X.h: @interface X : NSObject <NSCoding> { NSString *name; ... @property (nonatomic, retain) NSString *name; X.m: @implementation X @synthesize name; ... Main View Controller.h: @class X; @interface XViewController : UITableViewController { X *x; ... Main View Controller.m: @implementation XViewController @synthesize x; ... - (void)viewDidLoad { ... [self.x addObserver:self forKeyPath: @"name" options: (NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld) context:nil]; [super viewDidLoad]; } ... - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if ([keyPath isEqual:@"name"]) { NSLog(@"Found change to X"); [self.tableView reloadData]; } [super observeValueForKeyPath:keyPath ofObject:object change:change context:context]; } Child View Controller.m: (this correctly sets the value in the object in the child view controller) [self.x setValue:[[tempValues objectForKey:key] text] forKey:@"name"];

• Access static method from non static class possible in java and not in c#

  - by sagar_kool

  Access static method from non static class with object. It is not possible in C#. Where it is done by JAVA. How it works? example of java /** * Access static member of the class through object. */ import java.io.*; class StaticMemberClass { // Declare a static method. public static void staticDisplay() { System.out.println("This is static method."); } // Declare a non static method. public void nonStaticDisplay() { System.out.println("This is non static method."); } } class StaticAccessByObject { public static void main(String[] args) throws IOException { // call a static member only by class name. StaticMemberClass.staticDisplay(); // Create object of StaticMemberClass class. StaticMemberClass obj = new StaticMemberClass(); // call a static member only by object. obj.staticDisplay(); // accessing non static method through object. obj.nonStaticDisplay(); } } Output of the program: This is static method. This is static method. This is non static method. How to do this in C#? thanks in advance..

• TypeConverter prevents ApplyPropertyChanges in EntityFramework

  - by Felix

  I ran into an interesting problem (hopefully, interesting not just for me :) I am running Entity Framework 1 (.NET 3.5) and ASP.NET MVC 2. I have a Customer class that has many-to-one relationship with Country class (in other words, Country is a lookup table for customers - I described more in this post: http://stackoverflow.com/questions/2404801/explicit-casting-doesnt-work-in-default-model-binding ) I got TypeConverter to work; so I am getting a perfect object into controller's Post method. Create works fine; however, in Edit I am getting the following error when I call ApplyPropertyChanges: The existing object in the ObjectContext is in the Added state. Changes can only be applied when the existing object is in an unchanged or modified state. The controller code is fairly trivial: public ActionResult Edit(Customer customerToEdit) { if (ModelState.IsValid) { Customer cust = (Customer)context.GetObjectByKey( new EntityKey("BAEntities.Customers", "CustomerID", customerToEdit.CustomerID)); context.ApplyPropertyChanges(cust.EntityKey.EntitySetName, customerToEdit); context.SaveChanges(); } return View(...); } If I remove country from the form, it works fine; and if I assign dropdown value to EntityReference "manually" - it works as well. TypeConverter code is also fairly simple, but I've never used TypeConverter before, so I may be missing something here: public override object ConvertFrom(ITypeDescriptorContext typeContext, CultureInfo culture, object value) { if (value is string) { int countryID = Int16.Parse((string)value); Country country = (Country)context.GetObjectByKey( new EntityKey("BAEntities.Countries", "CountryID", countryID)); return country; } return base.ConvertFrom(typeContext, culture, value); }

• jQuery datepicker getMinDate '+1d'

  - by Adrian Adkison

  Once I have set the minDate property of a datepicker with the convenient string syntax $(elem).datepicker('option','minDate','+1d +3m'); how can I get the date object of the minDate? To help illustrate, there is a method $(elem).datepicker('getDate'); which returns the date that is entered in the input in the format of a date object. I would like the same thing but for datepicker('getMinDate'). There is an option like this $(elem).datepicker('option','minDate'); but this returns '+1d +3m' which is not helpful. I need the actual date object to compare with another date object. Any ideas?

• Correctly assigning value to a Core Data attribute with an integer data-type

  - by Gordon Fontenot

  I'm missing something here, and feeling like an idiot about it. I'm using a UIPickerView in my app, and I need to assign the row number to a 32-bit integer attribute for a Core Data object. To do this, I am using this method: -(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { object.integerValue = row; } This is giving me a warning: warning: passing argument 1 of 'setIntegerValue:' makes pointer from integer without a cast What am I mixing up here? --Edit 1-- Ok, so I can get rid of the warning by changing the method to do the following: NSNumber *number = [NSNumber numberWithInteger:row]; object.integerValue = rating; However, I still get a value of 0 for object.integerValue if I use NSLog to print it out. object.integerValue has a max value of 5, so I print out number instead, and then I'm getting a number above 62,000,000. Which doesn't seem right to me, since there are 5 rows. If I NSLog the row variable, I get a number between 0 and 5. So why do I end up with a completely different number after casting the number to NSNumber? --Edit 2-- Ok, so I'm realizing that there is some fundamental idea that I don't understand. I now understand that the 60 million + number can be cast back to the correct 0-5 number by using integerValue. So, it seems my question is how can I save an integer between 0-5 to the attribute if the NSNumber that is returned is over 60 million? Do I need to be using a different data type?

• Fastest way to call a COM objects method without using a RCW

  - by Nathan W

  I'm trying to find the cleanest and fastest way for calling a COM objects methods. I was using a RCW for the object but every time a new version of the third party COM object comes out its GUID changes which then renders the RCW useless, so I had to change and start using Type mytype = Type.GetTypeFromProgID("MyCOMApp.Application"); so that every time a new version of the COM object comes out I don't have to recomplie and redeploy my app. At the moment I am using refelection like mytype.InvokeMemeber but I feel it is so slow compared to just calling the RCW. How does everyone else tackle the problem of changing 3rd party COM object versions, but still maintaining the speed of a RCW?

• JSON htmlentities javascript

  Hi! I am using an XMLHttpRequest to POST a JSON string to PHP. The JSON object is created in JavaScript and using the JSON2.js from json.org to create an JSON string representing the object. JSON.stringify(object); Whenever the object contains a string which has a special character in it, e.g. é, JavaScript does not give any error but PHP receives an empty array [] Is there a JavaScript function which produces the exact same resutls as the PHP function htmlentities() The data is send via POST, so the following functions escape() encodeURI() encodeURIComponent() are a bit overkill. Thanks!

• jQuery fn.extend ({bla: function(){}} vs. jQuery.fn.bla

  - by tixrus

  OK I think I get http://stackoverflow.com/questions/1991126/difference-jquery-extend-and-jquery-fn-extend in that the general extend can extend any object, and that fn.extend is for plugin functions that can be invoked straight off the jquery object with some internal jquery voodoo. So it appears one would invoke them differently. If you use general extend to extend object obj by adding function y, then the method would attach to that object, obj.y() but if you use fn.extend then they are attach straight to the jquery object $.y().... Have I got that correct yes or no and if no what do I have wrong in my understanding? Now MY question: The book I am reading advocates using jQuery.fn.extend ({a: function(){}, b: function(){}}); syntax but in the docs it says jQuery.fn.a (function(){}); and I guess if you wanted b as well it would be jQuery.fn.b (function(){}); Are these functionally and performance-wise equivalent and if not what is the difference? Thank you very much. I am digging jQuery!

• How to pass EventArgument information from view to view model in WPF?

My Query: I want to invoke a view that show properties of custom object, when user double click on any row of ListView. The ListView double click command is binded to the ListViewDoublClick Command in the view model. The CustomObject is in the event argument of listview double click command. To acheive this I have to pass the custom object ( or an unique id property of custom object through which I can retrieve the custom object from the collection) as command parameter.

• Design question for WinForms (C#) app, using Entity Framework

  - by cdotlister

  I am planning on writing a small home budget application for myself, as a learning excercise. I have built my database (SQL Server), and written a small console application to interact with it, and test out scenarios on my database. Once I am happy, my next step would be to start building the application - but I am already wondering what the best/standard design would be. I am palnning on using Entity Framework for handling my database entities... then linq to sql/objects for getting the data, all running under a WinForms (for now) application. My plan (I've never used EF... and most of my development background is Web apps) is to have my database... with Entity Framework in it's own project.. which has the connection to the database. This project would expose methods such as 'GetAccount()', 'GetAccount(int accountId)' etc. I'd then have a service project that references my EF project. And on top of that, my GUI project, which makes the calls to my service project. But I am stuck. Lets say I have a screen that displays a list of Account types (Debit, Credit, Loan...). Once I have selected one, the next drop down shows a list of accounts I have that suite that account type. So, my OnChange event on my DropDown on the account type control will make a call to the serviceLayer project, 'GetAccountTypes()', and I would expect back a List< of Account Types. However, the AccountType object ... what is that? That can't be the AccountType object from my EF project, as my GUI project doesn't have reference to it. Would I have to have some sort of Shared Library, shared between my GUI and my Service project, with a custom built AccountType object? The GUI can then expect back a list of these. So my service layer would have a method: public List<AccountType> GetAccountTypes() That would then make a call to a custom method in my EF project, which would probably be the same as the above method, except, it returns an list of EF.Data.AccountType (The Entity Framework generated Account Type object). The method would then have the linq code to get the data as I want it. Then my service layer will get that object, and transform it unto my custom AccountType object, and return it to the GUI. Does that sound at all like a good plan?

  I'm wanting to do a simple edit form for our Issue Tracking app. For simplicity, the HttpGet Edit action looks something like this: // Issues/Edit/12 public ActionResult Edit(int id) { var thisIssue = edmx.Issues.First(i => i.IssueID == id); return View(thisIssue); } and then the HttpPost action looks something like this: [HttpPost] public ActionResult Edit(int id, FormCollection form) { // this is the dumb part where I grab the object before I update it. // concurrency is sidestepped here. var thisIssue = edmx.Issues.Single(c => c.IssueID == id); TryUpdateModel(thisIssue); if (ModelState.IsValid) { edmx.SaveChanges(); TempData["message"] = string.Format("Issue #{0} successfully modified.", id); return RedirectToAction("Index"); } return View(thisIssue); } Which works wonderfully. However, the concurrency check doesn't work because in the Post, I'm re-retreiving the current entity right before I attempt to update it. However, with EF, I don't know how to use the fanciness of SaveChanges() but attach my thisIssue to the context. I tried to call edmx.Issues.Attach(thisIssue) but I get The object cannot be attached because it is already in the object context. An object can only be reattached when it is in an unchanged state. How do I handle concurrency in MVC with EF and/or how do I properly Attach my edited object to the context? Thanks in advance

• PHP SoapClient() function returning a single XML string

  - by gjb

  I am having difficulty with the PHP SoapClient() function. The SOAP request is successful, but the response is returned as an object containing a single XML string with the key "any". For example: <?php $params = array('strUsername' => 'Test', 'strPassword' => 'Test'); $client=new SoapClient('http://www.example.com/webservice.asmx?wsdl', array('features' => SOAP_SINGLE_ELEMENT_ARRAYS)); $result = $client->strExampleCall($params); print_r($result); ?> This outputs the following: stdClass Object ( [strExampleCallResult] => stdClass Object ( [any] => <Response xmlns="" release="1.0.0" environment="Production" lang="en-GB"><ApplicationArea><Sender><SenderId>0</SenderId><ReferenceId>0</ReferenceId></Sender><Destination><DestinationId>1</DestinationId></Destination></ApplicationArea><DataArea><Result>1</Result></DataArea></Response> ) ) Subsequently, I cannot access properties of the object as I'd expect to: echo $result->strExampleCallResult->Response->DataArea->Result; Why isn't PHP parsing the SOAP response into properties of the returned object? I am using PHP 5.3.0 and believe the SOAP server is running .NET. Any suggestions will be much appreciated.

• Delayed "rendering" of WPF/Silverlight Dependency Properties?

  - by Aardvark

  Is there a way to know the first time a Dependency Property is accessed through XAML binding so I can actually "render" the value of the property when needed? I have an object (class derived from Control) that has several PointCollection Dependency Properties that may contain 100's or 1000's of points. Each property may arrange the points differently for use in different types shapes (Polyline, Polygon, etc - its more complicated then this, but you get the idea). Via a Template different XAML objects use TemplateBinding to access these properties. Since my object uses a Template I never know what XAML shapes may be in use for my object - so I never know what Properties they may or may not bind to. I'd like to only fill-in these PointCollections when they are actually needed. Normally in .NET I'd but some logic in the Property's getter, but these are bypassed by XAML data binding. I need a WPF AND Silverlight compatible solution. I'd love a solution that avoids any additional complexities for the users of my object.

• How to group a complex list of objects using LINQ?

  - by Daoming Yang

  I want to select and group the products, and rank them by the number of times they occur. For example, I have an OrderList each of order object has a OrderProductVariantList(OrderLineList), and each of OrderProductVariant object has ProductVariant, and then the ProductVariant object will have a Product object which contains product information. A friend helped me with the following code. It could be compiled, but it did not return any value/result. I used the watch window for the query and it gave me "The name 'query' does not exist in the current context". Can anyone help me? Many thanks. var query = orderList.SelectMany( o => o.OrderLineList ) // results in IEnumerable<OrderProductVariant> .Select( opv => opv.ProductVariant ) .Select( pv => p.Product ) .GroupBy( p => p ) .Select( g => new { Product = g.Key, Count = g.Count() });
