• Autocompletion in Eclipse for Roo project

  - by niklassaers

  Hi guys, I've got a Roo project where I've made a couple of entities, and when I load up the project in Eclipse it loads up fine, but if I i.e. make an instance MyEntity entity and then write entity. I don't get any of my properties (i.e. getMyField) in the autocompletion list. If I write entity.getMyField() it compiles fine, that is taken care of by the aspects. How do I enable autocompletion for functions generated by the aspects? Cheers Nik

• How do I work with WIndows Forms in WPF?

  - by xarzu

  How do I work with WIndows Forms in WPF? In my WPF program I created a Windows Form class. In this Form, I placed an OK button and I went into the properties of the button and set the DialogResult to OK. Now, I am calling this Dialog (Window Form) from the MainWindow.xaml.cs: dres = form.ShowDialog(); if (dres != DialogResult.OK) return; The compiler is complaining: Error 3 'System.Nullable<bool>' does not contain a definition for 'OK' and no extension method 'OK' accepting a first argument of type 'System.Nullable<bool>' could be found (are you missing a using directive or an assembly reference?)

• What is the "Dispatcher" design pattern?

  - by Ben Farmer

  What is the "dispatcher" pattern and how would I implement it in code? I have a property bag of generic objects and would like to have the retrieval delegated to a generic method. Currently, I have properties looking for a specific key in the bag. For example: private Dictionary<String, Object> Foo { get; set; } private const String WidgetKey = "WIDGETKEY"; public Widget? WidgetItem { get { return Foo.ContainsKey(WidgetKey) ? Foo[WidgetKey] as Widget: null; } set { if (Foo.ContainsKey(WidgetKey)) Foo[WidgetKey] = value; else Foo.Add(WidgetKey, value); } } It was suggested that this could be more generic with the "dispatcher" pattern, but I've been unable to find a good description or example. I'm looking for a more generic way to handle the property bag store/retrieve.

• Default Accessor Needed: Custom ConfigurationSection

  - by Mark

  I am totally confused by a simple Microsoft error message. When I run XSD.exe against an assembly that contains a custom ConfigurationSection (which in turn utilizes a custom ConfigurationElement and a custom ConfigurationElementCollection, as well as several ConfigurationProperties), I get the following error message: Error: There was an error processing 'Olbert.Entity.Utils.dll'. There was an error reflecting type 'Olbert.Entity.DatabaseConnection'. You must implement a default accessor on System.Configuration.ConfigurationLockCollection because it inherits from ICollection. Yet the class in question has a default accessor: public object this[int idx] { get { return null; } set { } } I realize the above doesn't do anything, but I don't need to access the element's properties by index. I'm just trying to work around the error message. So what's going on?

• Spring 3 - Custom Security

  - by Eqbal

  I am in the process of converting a legacy application from proprietary technology to a Spring based web app, leaving the backend system as is. The login service is provided by the backend system through a function call that takes in some parameter (username, password plus some others) and provides an output that includes the authroizations for the user and other properties like firstname, lastname etc. What do I need to do to weave this into Spring 3.0 security module. Looks like I need to provide a custom AuthenticationProvider implementation (is this where I call the backend function?). Do I also need a custom User and UserDetailsService implementation which needs loadUserByName(String userName)? Any pointers on good documentation for this? The reference that came with the download is okay, but doesn't help too much in terms of implementing custom security.

• Unable to view ChildWindows in Silverlight

  - by Doug Nelson

  So here is the deal. I have created a silverlight dll that contains two ChildWindow dialogs. These dialogs are self contained with a WCF service reference. I want to reuse these dialogs across multiple projects. I have added a reference to the dll in another project. I am able to new up the childWindow, however, I am not able to set the public properties on it and when I call the Show method, nothing is displayed. Not really sure where to start to figure out why this is not working.

• connection string reading data from excel in asp.net

  - by Greg

  Hello, I am trying to read data from excel file in asp.net. I have added the connection string to webConfig file: <add name="xls" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=HPM_DB.xls;Extended Properties=Excel 8.0"/> But it shows me an errormessage when I run this query: string query = "Select * from [IO_Definition$]"; IO_Definition is the name of the spreadsheet in my excel file. I also added the excel file to the App_Data folder of the website. The error is: The Microsoft Jet database engine could not find the object 'IO_Definition$'. Make sure the object exists and that you spell its name and the path name correctly. The thing is, when I write the absolute path of the excel file in the connectionString it does work. Is there anyway I can make it work without writing the absolute path? Thanks, Greg

• Iphone -- init method of an abstract class

  - by William Jockusch

  I want to create classes Car, Vehicle, and Airplane with the following properties: Car and Airplane are both subclasses of Vehicle. Car and Airplane both have an initWithString method. The acceptable input strings for Car's and Airplane's initWithString methods do not overlap. Vehicle is "almost abstract", in the sense that any initialized instance should be either a Car or an Airplane. It is possible to pass a string into Vehicle and get back an instance of Car, an instance of Airplane, or nil, depending on the input string. Any particular design pattern I should prefer? In particular for Vehicle's initWithString and/or newVehicleWithString methods.

• How are binding specified for Interface Builder plugins?

  - by Benedict Cohen

  I'm creating an Interface Builder plugin for an NSView subclass. I've been following the Interface Builder Plug-in Programming Guide but it's not answer all my questions. My class has one NSString property and 4 NSColor properties which I want to create bindings for at design time. I can't figure out where the bindings are specified in the plugin project. The documentation states that the Inspector Object is only for creating the Attribute Inspector. The class description file (.classdescription) lists outlets and actions but not bindings. Where do I specify the bindings for my class?

• Object does not support this propery or method IE & jQuery

  - by Mirko

  I am using jQuery and the cornerz plug in to get rounded corners on elements of the page without using images. In IE7 and 8 it fails and I get this error: "Object doesn't support this property or method" on this lines: if($.browser.msie && settings.fixIE) { var ow = $$.outerWidth(); var oh = $$.outerHeight(); Basically it complains about the outerWidth and outerHeight properties... The cornerz demo page (here) works perfectly on IE7 and 8 without throwing any error and it has got several examples...I do not know why this is happening Any suggestion will be appreciated Thanks in advance

• DataBinding and ErrorProvider - How to provide custom error messages?

  - by BeowulfOF

  We use BusinessObjects, implementing IDataErrorInfo and IEditableObject. BindingLists with those Objects are added to BindingSources, those are used to bind UserControls and DataGrids on the forms (WinForms). The BindingSource is additionally set as DataSource to the ErrorProvider of the form. We do use currently TextBoxes for Properties of Type int and short. They are validated inside the BusinessObjects with custom validation, like min/max values, etc. That works fine, since error message form our custom validations show up nicely next to the TextBox. However, if the input is greater than the value of an int (e.g. "9999999999") the BindingSource doesn't even try to enter that Value into the BusinesObject but instead gives the errormessage to the errorprovider like "The value for Int32 was too big.". We do not want to bother our users with "Int32" but want a custom errormessage for that. It is nice, that the BindingSource does provide this feature, but is it possible to provide custom error messages for this?

• Access Edit Mode Values of BindingSource Control

  - by Christopher Edwards

  I have a BindingSource control (http://msdn.microsoft.com/en-us/library/system.windows.forms.bindingsource.aspx) with a datasource of a (single) Linq object. If I change any of the properties of the underlying Linq-to-Sql object then all the other changes on the bound controls on the form are lost. Does anyone now why and how I work around it? I don't want to call EndEdit because this will commit the changes to the underlying object. I think this might be because my underlying object linq-to-sql object does not implement IEditableObject so the potental new values for the object fields are sort of stored in the forms controls. Can anyone either clarify what is going on and/or suggest a work around. Thanks!

• .NET Framework 4 RC on Windows server 2008 R2

  - by mare

  I've just installed .NET 4 on Windows SErver 2008 R2 x64 and I am getting 500 Internal Server Error with an ASP.NET MVC application which was previously running fine on 3.5. The application was upgraded from targeting 3.5 to target 4 and I personally built it today on my development machine (changed in VS - Properties to .NET Framework 4). On the server I installed .NET Framework 4 Client profile RC for x86 and x64 platforms and I created a new .NET 4 application pool in IIS and placed the web app in it. Also I have custom errors turned Off in web.config but even so no detailed error is displayed - just the plain IIS 7.5 500 Internal Server Error. Any suggestions?

• Is there a redmine plugin to create multiple issues at once?

  - by Jerph

  Redmine has a nice batch edit feature, but nothing equivalent for "batch create" (please correct me if I'm wrong!) FogBugz lets you quickly create multiple tickets with the same properties (type, status, assignment, etc.) via a ajax-ified text box at the bottom of any filtered view of tickets. Tickets created this way match the values of the filter (and the filter grouping value - there's a text-box at the bottom of each group). Toodledo has simpler option: it's "Add multiple tasks" feature is a textarea where each line is turned into an item. Is there a redmine plugin out there that adds functionality like either of the above?

• Memory leak with WPF & ItemsControl (VB.NET)

  - by Matt H.

  I have an ItemsControl that uses a DataTemplate to display properties in my customClass that implements INotifyPropertyChanged... Pretty straightforward... Some items in the DataTemplate use CommandBindings (such as buttons), and a few have some code-behind (yuck). When I empty the ItemsControl and set all instances of customClass = Nothing , no memory is released from my program. This becomes a problem pretty quickly! Any idea where I should start looking? I've even gone so far as to completely traverse the visual tree of each DataTemplate instance and set each Visual = Nothing. I'm not really if that's supposed to have any effect though.

• Is there a SortedList<T> class in .net ? (not SortedList<Key,Value> which is actually a kind of Sort

  - by Brann

  I need to sort some objects according to their contents (in fact according to one of their properties, which is NOT the key and may be duplicated between different objects) .net provides two classes (SortedDictionnary and SortedList), and both are some kind of Dictionaries. The only difference (AFAIK) is that SortedDictionnary uses a binary tree to maintain its state whereas SortedList does not and is accessible via an index. I could achieve what I want using a List, and then using its Sort() method with a custom implementation of IComparer, but it wouldn't be time-efficient as I would sort the whole List each time I insert a new object, whereas a good SortedList would just insert the item at the right position. What I need is a SortedList class with a RefreshPosition(int index) to move only the changed (or inserted) object rather than resorting the whole list each time an object inside changes. Am I missing something obvious ?

• Joomla Template Parameters and params.ini

  - by Moak

  I am using wamp and creating a Joomla template with changeable parameters. initially the message is The parameter file \templates\ssc_2010\params.ini is writable! once I make changes everything works as expected, except now i get the message: The parameter file \templates\ssc_2010\params.ini is unwritable! One solution is to brows to the directory, right click the file, select properties, and uncheck read-only. Again the file is writable but once I modify the parameters again it becomes read only again. I'm quite lazy and would like to prevent this from happening again, I've notice this happening in past projects, but now I have to work a lot with parameters so it becomes quite boring doing manual labor like that :P

• How do I distinguish a SharePoint file update as being from a file upload?

  - by ccomet

  In SharePoint, when an item is first added to a document library, it fires the ItemAdded and ItemAdding events as expected. And if you upload the same filename to update the existing file, it will fire off ItemUpdated and ItemUpdating events, likewise as expected. However, I have been unsuccessful at determining whether this kind of action has actually occurred or not. Or, more specifically, I am entirely unable to differentiate between the following: An item is updated because someone uploaded a new file but did nothing to any of the form fields. An item is updated because someone hit "OK" but did nothing to any of the form fields. Is there actually a way to distinguish these kinds of updates? There appears to be nothing in event properties that contains this information, nor in the version history for both the list item and the file itself. I have even tried comparing the files themselves via OpenBinary(), but in both mentioned cases I still get the same result. Thank you in advance for any help!

• Linking Boost to my C++ project in Eclipse

  - by MahlerFive

  I'm trying to get the Boost library working in my C++ projects in Eclipse. I can successfully build when using header-only libraries in Boost such as the example simple program in the "Getting Started" guide using the lambda header. I cannot get my project to successfully link to the regex Boost library as shown later in the guide. Under my project properties - c/c++ build - settings - tool settings tab - libraries, I have added "libboost_regex" to the Libraries box, and "C:\Program Files\boost\boost_1_42_0\bin.v2\libs" to the Library search path box since this is where all the .lib files are. I've even tried adding "libboost_regex-mgw34-mt-d-1_42.lib" to the libraries box instead of "libboost_regex" since that is the exact file name, but this did not work either. I keep getting an error that says "cannot find -llibboost_regex" when I try to build my project. Any ideas as to how I can fix this?

• Problem with lazy loading implementation

  - by Mehran

  Hi, I have implemented lazy loading in my program. it's done through a proxy class like: class Order { public virtual IList<Item> Items {get; set;} } class OrderProxy { public override IList<Item> Items { get { if (base.Items == null) Items = GetItems(base.OrderID); return base.Items; } set { base.Items = value; } } } the problem is that whenever i instantiate proxy class,without even touching the Items property, it tries to load Items! as you may know,i want to instantiate proxy class and return the instance to BLL instead of domain object itself. what's the problem? Does .NET CLR access(read) properties in a class, when it's instatiating the class? any other methods? Thanks

• How do I do automatic data serialization of data objects in Haskell

  - by Adam Gent

  One of the huge benefits in languages that have some sort of reflection/introspecition is that objects can be automatically constructed from a variety of sources. For example in Java I can use the same objects for persisting to a db (with Hibernate) serializing to XML (with JAXB) or serializing to JSON (json-lib). You can do the same in Ruby and Python also usually following some simple rules for properties or annotations for Java. Thus I don't need lots "Domain Transfer Objects". I can concentrate on the domain I am working in. It seems in very strict FP like Haskell and Ocaml this is not possible. Particularly Haskell. The only thing I have seen is doing some sort of preprocessing or meta-programming (ocaml). Is it just accepted that you have to do all the transformations from the bottom upwards? In other words you have to do lot of boring work to turn a data type in haskell into JSON/XML/DB Row object and back again into a data object.
