• could not resolve property (complex properties)

  - by felipeoriani

  I have a asp.net mvc application with NHibernate and I do not know how to resolve a problem to query some data. I have this query: // create query var query = session.QueryOVer<Laudo>().Fetch(x => x.Equipament).Eager; // add some filters if (idEquipament.HasValue) query = query.And(x => x.Equipament.Id == idEquipament.Value); //I got the error here... if (idCompany.HasValue) query = query.And(x => x.Equipament.Company.Id == idCompany.Value); When I try to execute this query, I've got an exception with this message: "could not resolve property: Equipament.Company.Id of: DomainModel.Laudo" what can I do to fix this problem? Thanks

• Business object and linq2SQL

  - by Overdose

  What is the optimal way to write the code which interacts with DB using linq2SQL? I need to add some business logic to the entities. So I guess there are two ways: Write some wrapper class. The main minus is that many fields are the same, so i don't feel it as DRY style. Add business logic methods to linq2sql entities(these classes are partial) directly ???

• Change query to use a LEFT join

  - by Craig

  I have a query which is failing, as it needs to be using LEFT JOIN, as opposed to the default INNER JOIN used by the 'join' syntax: var users = (from u in this._context.Users join p in this._context.Profiles on u.ProfileID equals p.ID join vw in this._context.vw_Contacts on u.ContactID equals vw.ID orderby u.Code select new { ID = u.ID, profileId = p.ID, u.ContactID, u.Code, u.UserName, vw.FileAs, p.Name, u.LastLogout, u.Inactive, u.Disabled }).ToList(); How would i re-write this so that is utilises a LEFT join?

• Using PHP Redirect Script together with Custom Fields (WordPress)? [on hold]

  - by Alex Scherer

  I am currently trying to make yoast's link cloaking script ( Yoast.com script manual // Github Script files ) work together with the Wordpress plugin Advanced Custom Fields. The script fetches 2 values (redirect id, redirect url) via GET and then redirects to this particular URL which is defined in a .txt file called redirects.txt I would like to change the script, so that I can define both the id and redirection URL via custom fields on each post in my WP dashboard.. I would be really happy if someone could help me to code something that does the same as the script above but without using a redirects.txt file to save the values but furthermore gets those values from custom fields. Best regards ! Alex

• Android: Layouts and views or a single full screen custom view?

  - by futlib

  I'm developing an Android game, and I'm making it so that it can run on low end devices without GPU, so I'm using the 2D API. I have so far tried to use Android's mechanisms such as layouts and activities where possible, but I'm beginning to wonder if it's not easier to just create a single custom view (or one per activity) and do all the work there. Here's an example of how I currently do things: I'm using a layout to display the game's background as an image view and the square game area, which is a custom view, centered in the middle. What would you say? Should I continue to use layouts where possible or is it more common/reasonable to just use a large custom view? I'm thinking that this would probably also make it easier to port my code to other platforms.

• Using Microsoft.Reporting.WebForms.ReportViewer in a custom SharePoint WebPart

  - by iHeartDucks

  I have a requirement where I have to display some data (from a custom db) and let the user export it to an excel file. I decided to use the ReportViewer control present in Microsoft.Reporting.WebForms.ReportViewer. I added the required assembly to the project references and I add the following code to test it out protected override void CreateChildControls() { base.CreateChildControls(); objRV = new Microsoft.Reporting.WebForms.ReportViewer(); objRV.ID = "objRV"; this.Controls.Add(objRV); } The first error asked me to add this line in the web.config which I did and the next error says The type 'Microsoft.SharePoint.Portal.Analytics.UI.ReportViewerMessages, Microsoft.SharePoint.Portal, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' does not implement IReportViewerMessages Is it possible to use ReportViewer in my custom Web Part? I rather not bind a repeater and write my own export to excel code. I want to use something which is already built by Microsoft? Any ideas on what I can reuse? Edit I commented the following line <add key="ReportViewerMessages"... and now my code looks like this after I added a data source to it protected override void CreateChildControls() { base.CreateChildControls(); objRV = new Microsoft.Reporting.WebForms.ReportViewer(); objRV.ID = "objRV"; objRV.Visible = true; Microsoft.Reporting.WebForms.ReportDataSource datasource = new Microsoft.Reporting.WebForms.ReportDataSource("test", GroupM.Common.DB.GetAllClientCodes()); objRV.LocalReport.DataSources.Clear(); objRV.LocalReport.DataSources.Add(datasource); objRV.LocalReport.Refresh(); this.Controls.Add(objRV); } but now I do not see any data on the page. I did check my db call and it does return a data table with 15 rows. Any ideas why I don't see anything on the page?

• How to add custom SOAP-Header element to the generated WSDL in Spring-WS

  - by Petr Macek

  Hi, we are migrating from WebLogic web-services to Spring-WS (1.5.X). There is currently one issue we are facing: We need to pass a context object (on WLS it is passed as SOAP-Header element) to other services that are still running on WLS from the Spring-WS powered service. The header element is still formulated on client side and the newly created WS (Spring-WS) should just pass it to other services. I can imagine how the custom element would be passed: override the doWithMessage(WebServiceMessage message) method... Is there a way to generate the wsdl with the help of DefaultWsdl11Definition to contain that custom header element? See the example: <wsdl:operation name="GetSomeInformation"> <soap:operation soapAction="http://www.dummyservice.com/InformationService/GetSomeInformation" /> <wsdl:input> <soap:body use="literal" /> <soap:header message="ctx:ServiceContextMessage" part="serviceContext" use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> <wsdl:fault name="Error"> <soap:fault name="Error" use="literal" /> </wsdl:fault> </wsdl:operation> Thanks for help

  I am having difficulties to use my custom IComparer for my SortedDictionary<. The goal is to put email addresses in a specific format ([email protected]) as the key, and sort by last name. When I do something like this: public class Program { public static void Main(string[] args) { SortedDictionary<string, string> list = new SortedDictionary<string, string>(new SortEmailComparer()); list.Add("[email protected]", "value1"); list.Add("[email protected]", "value2"); foreach (KeyValuePair<string, string> kvp in list) { Console.WriteLine(kvp.Key); } Console.ReadLine(); } } public class SortEmailComparer : IComparer<string> { public int Compare(string x, string y) { Regex regex = new Regex("\\b\\w*@\\b", RegexOptions.IgnoreCase | RegexOptions.CultureInvariant | RegexOptions.IgnorePatternWhitespace | RegexOptions.Compiled ); string xLastname = regex.Match(x).ToString().Trim('@'); string yLastname = regex.Match(y).ToString().Trim('@'); return xLastname.CompareTo(yLastname); } } I get this ArgumentException: An entry with the same key already exists. when adding the second item. I haven't worked with a custom IComparer for a SortedDictionary before, and I fail to see my error , what am I doing wrong?

• MKMapKit custom annotations being added to map, but are not visible on the map

  - by culov

  I learned a lot from the screencast at http://icodeblog.com/2009/12/21/introduction-to-mapkit-in-iphone-os-3-0/ , and ive been trying to incorporate the way he creates a custom annotation into my iphone app. He is hardcoding annotations and adding them individually to the map, whereas i want to add them from my data source. So i have an array of objects with a lat and a lng (ive checked that the values are within range and ought to be appearing on the map) that i iterate through and do [mapView addAnnotation:truck] once this process is completed, i check the number of annotations on the map with [[mapView annotations] count] and its equal to the number it ought to be, so all the annotations are getting added onto the mapView, but for some reason I cant see any annotations in the simulator. I've compared my code with his in all the pertinent places many times, but nothing seems to stand out as being incorrect. Ive also reviewed my code for the last several hours trying to find a point where I do something wrong, but nothing is coming to mind. The images are named just as they are assigned in the custom AnnotationView, the loadAnnotation function is done properly, etc... i dont know what it could be. so i suppose if i could have the answer to one question it would be, what are possible causes for a mapView to contain several annotations, but to not show any on the map? Thanks

• Creating a 'Custom Designer' Visual Studio 2010 Add-in

  - by Daniel I-S

  A major part of our work is creating and manipulating certain XML files, for which have a custom editor. The editor is starting to get creaky and we are looking at building a replacement. Since VS2010 has recently arrived, ostensibly with an improved add-in architecture (MEF?), I am interested in the possibility of building the editor as a custom editor within Visual Studio. It would have to appear in the same way as the code editor or the Designer - a tab item, of which there can be many open at once, containing the GUI we use to edit the files. It would integrate with VS's Edit menu. It could use the output window to display messages. It would appear the same as any other editor within Visual Studio. Right now, I am looking for examples of add-ins that work in a similar way - ideally with source code - to see whether this model would suit our requirements. I am also looking for any documentation or tutorials relevant to creating a VS2010 add-in, or information about VS2008 add-ins if this is still relevant. Any input is welcome. Thanks!

• Problem with boost::find_format_all, boost::regex_finder and custom regex formatter (bug boost 1.42)

  - by Nikko

  I have a code that has been working for almost 4 years (since boost 1.33) and today I went from boost 1.36 to boost 1.42 and now I have a problem. I'm calling a custom formatter on a string to format parts of the string that match a REGEX. For instance, a string like: "abc;def:" will be changed to "abc\2Cdef\3B" if the REGEX contains "([;:])" boost::find_format_all( mystring, boost::regex_finder( REGEX ), custom_formatter() ); The custom formatter looks like this: struct custom_formatter() { template< typename T > std::string operator()( const T & s ) const { std::string matchStr = s.match_results().str(1); // perform substitutions return matchStr; } } This worked fine but with boost 1.42 I know have "non initialized" s.match_results() which yield to boost::exception_detail::clone_implINS0_::error_info_injectorISt11logic_errorEEEE - Attempt to access an uninitialzed boost::match_results< class. This means that sometimes I am in the functor to format a string but there is no match. Am I doing something wrong? Or is it normal to enter the functor when there is no match and I should check against something? for now my solution is to try{}catch(){} the exception and everything works fine, but somehow that doesn't feel very good. EDIT1 Actually I have a new empty match at the end of each string to parse. EDIT2 : one solution inspired by ablaeul template< typename T > std::string operator()( const T & s ) const { if( s.begin() == s.end() ) return std::string(); std::string matchStr = s.match_results().str(1); // perform substitutions return matchStr; } *EDIT3 Seems to be a bug in (at least) boost 1.42 *

• Custom Facelets components and attributes defined in taglib

  - by michael lucas

  Defining custom components in Facelets is easy and quick but there's one thing I can't figure out. Is it possible with Facelets to define what attributes my custom component has? I.e: I've created a component which is used in such a way: <blue:modalWindow id="editFeesWizard" width="500" height="440" title="Wizard"> and is defined in taglib.xml as follows: <!DOCTYPE facelet-taglib PUBLIC "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN" "http://java.sun.com/dtd/facelet-taglib_1_0.dtd"> <facelet-taglib> <namespace>http://blue/</namespace> <tag> <tag-name>modalWindow</tag-name> <source>components/modalWindow.xhtml</source> </tag> </facelet-taglib> Taglib doesn't contain any information on component attributes (id, width, height, title) and IDE cannot therefore check my syntax nor can it suggest attributes while I'm typing. I cannot find anything on this subject in Facelets documentation. Thought you could help. Thanks!

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

  - by swdeveloper

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

• custom view on iphone's native media player(MPMoviePlayerController)

  - by sneha

  I am building an application that implements a custom view on iPhone’s native media player. I want your help in deciding directions to lay this effort. At present I have find out that iPhone SDK doesn’t support APIs to customize media player. I need these things in the player: I would like to have custom views i.e. want to change all control buttons on player like Play/Pause, seek bar etc. The background of player will also need to be different. The player has to play audio or video file from local/remote location. Can i use MPMoviePlayerController if it can be customized (How to do it ??). However, any other third party player approved by iPhone which has an ability to download and play the media file from local/remote location is also fine. It will be great to have an access to media player buffer so that it can be encrypted. I have following questions: 1.Any help in building/customizing player..... 2.Do you see issues in signing of application? 3.Does Apple have any restrictions on customizing media player? 4.Any sample iPhone application where media player is customized Any help in this regard is highly appreciated.

• How to deal with calculated values with Dependency Properties on a custom WPF control

  - by jpierson

  To summarize what I'm doing, I have a custom control that looks like a checked listbox and that has two dependency properties one that provides a list of available options and the other that represents a enum flag value that combines the selection options. So as I mentioned my custom control exposes two different DependencyProperties, one of which is a list of options called Options and the other property called SelectedOptions is of a specific Enum type that uses the [Flags] attribute to allow combinations of values to be set. My UserControl then contains an ItemsControl similar to a ListBox that is used to display the options along with a checkbox. When the check box is checked or unchecked the SelectedOptions property should be updated accordingly by using the corresponding bitwise operation. The problem I'm experiencing is that I have no way other than resorting to maintaining private fields and handling property change events to update my properties which just feels unatural in WPF. I have tried using ValueConverters but have run into the problem that I can't really using binding with the value converter binding so I would need to resort to hard coding my enum values as the ValueConverter parameter which is not acceptable. If anybody has seen a good example of how to do this sanely I would greatly appreciate any input. Side Note: This has been a problem I've had in the past too while trying to wrap my head around how dependency properties don't allow calculated or deferred values. Another example is when one may want to expose a property on a child control as a property on the parent. Most suggest in this case to use binding but that only works if the child controls property is a Dependency Property since placing the binding so that the target is the parent property it would be overwritten when the user of the parent control wants to set their own binding for that property.

• Custom Membership in ASP.NET MVC 2

  - by Interfector

  Hello, I'm trying to make my Custom Membership starting from ASP.NET's. I have a users table created by me which has as Primary Key a Guid UserId, exactly the sames as ASP.NET's default user and membership table. I have all the Foreign Key relationships built. However, I cannot insert the user into my custom users table. The data gets inserted correctly into the default ASP.NET's tables. I have tried the following scenarios: First version Receive the user model from POST call the CreateUser method of the Membership.class (stuff gets inserted) without modifying the user object, I try to insert it using EF's AddObject I receive the following error: "Cannot insert the value NULL into column 'LoweredUserName', table 'asp.dbo.aspnet_Users'; column does not allow nulls. INSERT fails.\r\nThe statement has been terminated."} System.Exception {System.Data.SqlClient.SqlException The error actually makes sense as EF's AddObject doesn't know how to create the LoweredUserName value, and I don't want to do it, this is ASP.NET's job. Second version Receive the user model from POST call the CreateUser method of the Membership.class (stuff gets inserted) Get the Guid of the freshly inserted system user get the ASP.NET's User object and overwrite that of user.User get the ASP.NET's Membership object and overwrite that of user.Membership (remember the FKs) try again EF's AddObject new error {"The relationship between the two objects cannot be defined because they are attached to different ObjectContext objects."} System.Exception {System.InvalidOperationException} Don't know what this is, but it certenly doesn't make any sense for me. After some googleing I think that it has something to do with the context, but as I'm a beginner I don't know how to fix it. Any ideeas on how to accomplish this task are more than welcomed, especially if they follow some good practices. Thx
