• ruby on rails-Problem with the selection form helper

  - by winter sun

  Hello I have a form in witch users can add their working hours view them and edit them (All in one page). When adding working hours the user must select a project from a dropdown list. In case the action is adding a new hour record the dropdown field should remain empty (not selected) in case the action is edit the dropdown field should be selected with the appropriate value. In order to overcome this challenge I wrote the following code <% if params[:id].blank?%> <select name="hour[project_id]" id="hour_project_id"> <option value="nil">Select Project</option> <% @projects.each do|project|%> <option value="<%=project.id %>"><%=project.name%></option> <% end%> </select> <% else %> <%= select('hour','project_id', @projects.collect{|project|[project.name,project.id]},{:prompt => 'Select Project'})%> <% end %> So in case of save action I did the dropdown list only with html, and in case of edit action I did it with the collect method. It works fine until I tried to code the errors. The problem is that when I use the error method: validates_presence_of :project_id it didn't recognize it in the html form of the dropdown list and don’t display the error message (its working only for the dropdown with the collect method). I will deeply appreciate your instructions and help in this matter

• What version of .NET containing RuntimeMethodHandle.EmptyHandle?

  - by user299990

  No one answers my question in http://stackoverflow.com/questions/1295344/difference-between-activator-createinstance-and-typeoft-invokemember-with-b/2500960#2500960. I guess that the issue is closed and I am asking here again. Ben M have a nice function which I need for a project. The function is - public static T CreateInstance() { bool bNeedSecurityCheck = true; bool canBeCached = false; RuntimeMethodHandle emptyHandle = RuntimeMethodHandle.EmptyHandle; return (T) RuntimeTypeHandle.CreateInstance(typeof(T) as RuntimeType, true, true, ref canBeCached, ref emptyHandle, ref bNeedSecurityCheck); } I am using .NET 3.5 and Visual studio 2008. It gives the error "EmptyHandle type name does not exist in the type System.RuntimeMethodHandle". Then I used "RuntimeMethodHandle emptyHandle = new RuntimeMethodHandle();". Another error presents. RuntimeTypeHandle does not have a CreateInstance method either. Activator has. But it does not take any ref parameter. Thanks for clarification in advance!

• Close TCP connection when owner process is already killed

  - by Otiel

  I have a Windows service that - when it starts - opens some WCF services to listen on the 8000 port. It happens that this service crashes sometimes. When it does, the TCP connection is not released, thus causing my service to throw an exception if I try to start it again: AddressAlreadyInUseException: There is already a listener on IP endpoint 0.0.0.0:8000 Some observations: When running CurrPorts or netstat -ano, I can see that the 8000 port is still in use (in LISTENING state) and is owned by the Process ID XXX that corresponded to my service process ID. But my service has already crashed, and does not appear in the Task Manager anymore. Thus I can't kill the process to free the port! Of course, running taskkill /PID XXX returns: ERROR: The process "XXX" not found. When running CurrPorts or netstat -b, I can see that the process name involved in creating the listening port is System, and not as MyService.exe (whereas it is MyService.exe when my service is running). I tried to use CurrPorts to close the connection, but I always get the following error message: Failed to close one or more TCP connections. Be aware that you must run this tool as admin in order to close TCP connections. (Useless to say, I do run CurrPorts as Administrator...) TCPView is not much help either: the process name associated to the 8000 port is <non-existent>, and doing "End process" or "Close connection" has no effect. I tried to see if there was not a child process associated with the PID XXX using Process Explorer, but no luck here. If I close my service properly (before it crashes), the TCP connection is correctly released. This is normal, as I close the WCF service hosts in the OnStop() event of my service. The only way I found to release the connection is to restart the server (which is not convenient in a production environment as you can guess). Waiting does not help, the TCP connection is never released. How can I close the connection without restarting the Windows server? PS: found some questions extremely similar to mine.

• How to asynchronously read to std::string using Boost::asio?

  - by SpyBot

  Hello. I'm learning Boost::asio and all that async stuff. How can I asynchronously read to variable user_ of type std::string? Boost::asio::buffer(user_) works only with async_write(), but not with async_read(). It works with vector, so what is the reason for it not to work with string? Is there another way to do that besides declaring char user_[max_len] and using Boost::asio::buffer(user_, max_len)? Also, what's the point of inheriting from boost::enable_shared_from_this<Connection> and using shared_from_this() instead of this in async_read() and async_write()? I've seen that a lot in the examples. Here is a part of my code: class Connection { public: Connection(tcp::acceptor &acceptor) : acceptor_(acceptor), socket_(acceptor.get_io_service(), tcp::v4()) { } void start() { acceptor_.get_io_service().post( boost::bind(&Connection::start_accept, this)); } private: void start_accept() { acceptor_.async_accept(socket_, boost::bind(&Connection::handle_accept, this, placeholders::error)); } void handle_accept(const boost::system::error_code& err) { if (err) { disconnect(); } else { async_read(socket_, boost::asio::buffer(user_), boost::bind(&Connection::handle_user_read, this, placeholders::error, placeholders::bytes_transferred)); } } void handle_user_read(const boost::system::error_code& err, std::size_t bytes_transferred) { if ( err or (bytes_transferred != sizeof(user_)) ) { disconnect(); } else { ... } } ... void disconnect() { socket_.shutdown(tcp::socket::shutdown_both); socket_.close(); socket_.open(tcp::v4()); start_accept(); } tcp::acceptor &acceptor_; tcp::socket socket_; std::string user_; std::string pass_; ... };

• A monkey could do this better - Access to and availability of private member functions in C++

  - by David

  I am wandering the desert of my brain. I'm trying to write something like the following: class MyClass { // Peripherally Related Stuff public: void TakeAnAction(int oneThing, int anotherThing) { switch(oneThing){ case THING_A: TakeThisActionWith(anotherThing); break; //cases THINGS_NOT_A: }; private: void TakeThisActionWith(int thing) { string outcome = new string; outcome = LookUpOutcome(thing); // Do some stuff based on outcome return; } string LookUpOutcome(int key) { string oc = new string; oc = MyPrivateMap[key]; return oc; } map<int, string> MyPrivateMap; Then in the .cc file where I am actually using these things, while compiling the TakeAnAction section, it [CC, the solaris compiler] throws an an error: 'The function LookUpOutcome must have a prototype' and bombs out. In my header file, I have declared 'string LookUpOutcome(int key);' in the private section of the class. I have tried all sorts of variations. I tried to use 'this' for a little while, and it gave me 'Can only use this in non-static member function.' Sadly, I haven't declared anything static and these are all, putatively, member functions. I tried it [on TakeAnAction and LookUp] when I got the error, but I got something like, 'Can't access MyPrivateMap from LookUp'. MyPrivateMap could be made public and I could refer to it directly, I guess, but my sensibility says that is not the right way to go about this [that means that namespace scoped helper functions are out, I think]. I also guess I could just inline the lookup and subsequent other stuff, but my line-o-meter goes on tilt. I'm trying desperately not to kludge it.

• lost session after redirect_to

  - by PeterWong

  I encountered a strange performance in my current project, which is about session. The strange part is it was normal in Safari but failed in other browsers (includes chrome, firefox and opera). There is a registration form for input of part of the key information (email, password, etc) and is submitted to an action called "create" This is the basic code of create action: @account = Account.new(params[:account]) if @account.save ApplicationController.current_account = @account session[:current_account] = ApplicationController.current_account session[:account] = ApplicationController.current_account.id email = @account.email Mailer.deliver_account_confirmation(email) flash[:type] = "success" flash[:notice] = "Successfully Created Account" redirect_to :controller => "accounts", :action => "create_step_2" else flash[:type] = "error" flash[:title] = "Oops, something wasn't right." flash[:notice] = "Mistakes are marked below in red. Please fix them and resubmit the form. Thanks." render :action => "new" end Also I created a before_filter in the application controller, which has the following code: ApplicationController.current_account = Account.find_by_id(session[:current_account].id) unless session[:current_account].blank? For Safari, there is no any problem. But for the other browsers, the session[:current_account] does not exist and so produced the following error message: RuntimeError in AccountsController#create_step_2 Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id Please could anyone help me?

• Grails , how do I get an object NOT to save

  - by user350325

  Hello I am new to grails and trying to create a form which allows a user to change the email address associated with his/her account for a site I am creating. It asks for the user for their current password and also for the new email address they want to use. If the user enters the wrong password or an invalid email address then it should reject them with an appropriate error message. Now the email validation can be done through constraints in grails, but the password change has to match their current password. I have implemented this check as a method on a service class. See code below: def saveEmail = { def client = ClientUser.get(session.clientUserID) client.email = params.email if(clientUserService.checkPassword(session.clientUserID , params.password) ==false) { flash.message = "Incorrect Password" client.discard() redirect(action:'changeEmail') } else if(!client.validate()) { flash.message = "Invalid Email Address" redirect(action:'changeEmail') } else { client.save(); session.clientUserID = null; flash.message = "Your email address has been changed, please login again" redirect(controller: 'clientLogin' , action:'index') } } Now what I noticed that was odd was that if I entered an invalid email then it would not save the changes (as expected) BUT if I entered the wrong password and a valid email then it would save the changes and even write them back into the database even though it would give the correct "invalid password" error message. I was puzzled so set break points in all the if/else if/else blocks and found that it was hitting the first if statement as expected and not hitting the others , so it would never come accross a call to the save() method, yet it was saved anyway. After a little research I came accross documentation for the discard() method which you can see used in the code above. So I added this but still no avail. I even tried using discard then reloading the client object from the DB again but still no dice. This is very frustrating and I would be grateful for any help, since I think that this should surely not be a complicated requirement!

• (Not So) Silly Objective-C inheritance problem when using property - GCC Bug?

  - by Ben Packard

  Update 2 - Many people are insisting I need to declare an iVar for the property. Some are saying not so, as I am using Modern Runtime (64 bit). I can confirm that I have been successfully using @property without iVars for months now. Therefore, I think the 'correct' answer is an explanation as to why on 64bit I suddenly have to explicitly declare the iVar when (and only when) i'm going to access it from a child class. The only one I've seen so far is a possible GCC bug (thanks Yuji). Not so simple after all... Update - I messed up one line of the original copy and paste - corrected. The @property call was missing (nonatomic, retain) but is a red herring - STILL NEED AN ANSWER! Thanks. I've been scratching my head with this for a couple of hours - I haven't used inheritance much. Here I have set up a simple Test B class that inherits from Test A, where an ivar is declared. But I get the compilation error that the variable is undeclared. This only happens when I add the property and synthesize declarations - works fine without them. TestA Header: #import <Cocoa/Cocoa.h> @interface TestA : NSObject { NSString *testString; } @end TestA Implementation is empty: #import "TestA.h" @implementation TestA @end TestB Header: #import <Cocoa/Cocoa.h> #import "TestA.h" @interface TestB : TestA { } @property (nonatomic, retain) NSString *testProp; @end TestB Implementation (Error - 'testString' is undeclared) #import "TestB.h" @implementation TestB @synthesize testProp; - (void)testing{ NSLog(@"test ivar is %@", testString); } @end

• Unity Configuration and Same Assembly

  - by tyndall

  I'm currently getting an error trying to resolve my IDataAccess class. The value of the property 'type' cannot be parsed. The error is: Could not load file or assembly 'TestProject' or one of its dependencies. The system cannot find the file specified. (C:\Source\TestIoC\src\TestIoC\TestProject\bin\Debug\TestProject.vshost.exe.config line 14) This is inside a WPF Application project. What is the correct syntax to refer to the Assembly you are currently in? is there a way to do this? I know in a larger solution I would be pulling Types from seperate assemblies so this might not be an issue. But what is the right way to do this for a small self-contained test project. Note: I'm only interested in doing the XML config at this time, not the C# (in code) config. UPDATE: see all comments My XML config: <configuration> <configSections> <section name="unity" type="Microsoft.Practices.Unity.Configuration.UnityConfigurationSection, Microsoft.Practices.Unity.Configuration" /> </configSections> <unity> <typeAliases> <!-- Lifetime manager types --> <typeAlias alias="singleton" type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager, Microsoft.Practices.Unity" /> <typeAlias alias="external" type="Microsoft.Practices.Unity.ExternallyControlledLifetimeManager, Microsoft.Practices.Unity" /> <typeAlias alias="IDataAccess" type="TestProject.IDataAccess, TestProject" /> <typeAlias alias="DataAccess" type="TestProject.DataAccess, TestProject" /> </typeAliases> <containers> <container name="Services"> <types> <type type="IDataAccess" mapTo="DataAccess" /> </types> </container> </containers> </unity> </configuration>

As I understand it everything is stored as a pointer so I did try adding an additional constructor that took a pointer to foo but to no avail.

• Using Scala and StringTemplate, how do I loop through a Map

  - by Marcus Kazmierczak

  I have my environment setup nicely using Scala, StringTempalte within the Google AppEngine. I am having trouble looping through a Map and getting it to display in the template. When I assign a simple List of just Strings to the template it works using: In Scala Servlet: var photos = List[String]() //... get photo url and title ... photos = photo_url :: photos template.setAttribute("photos", photos: _*) In Template: $photos: { photo| <div><img src="$photo$_s.jpg"></div> }$ The above works. However, any attempt of creating a Map using url and title and assigning to the template gives me an error. Here is my attempt, which does not work: In Scala Servlet: var photos = List[Map[String,String]]() //... get photo url and title ... photos = Map("url" -> url, "title" -> title) :: photos template.setAttribute("photos", photos: _*) In Template: $photos: { photo| <div><img src="$photo.url$_s.jpg" title="$photo.title$"></div> }$ This gives me the following error Class scala.collection.immutable.Map$Map2 has no such attribute: title in template context Thoughts / Ideas ?

• Validation L2S question

  - by user158020

  This may be a bit winded because I am new to wpf. I have created a partial class for an entity in my L2S class that is primarily used for validation. It implements the onchanging and onvalidate methods. I am trying to use the MVVM pattern, and in a window/view I have set the datacontext in the xaml: <Window.DataContext> <vm:StartViewModel /> </Window.DataContext> when a user leaves a required field in the view blank, the onchanging event of the partial class is fired when I close the form, not when I save the data. So, if a user leaves the textbox blank, the old value is retained and the onchaging method is fired, but I have no idea how to alert the user of the resulting error. here is my onchanging code in the partial class: partial void Ondocument_titleChanging(string value) { if (value.Length == 0) throw new Exception("Document title is required."); if (value.Length > 256) throw new Exception("Document title cannot be longer than 256 characters."); } throwing an exception doesn't notify the user of the error. it just allows the form to close and rejects the changes to the textbox. hope this makes sense... edit: this example was taken from Scott Guthries article here: http://aspalliance.com/1427_LINQ_to_SQL_Part_5__Binding_UI_using_the_ASPLinqDataSource_Control.5

• setting default value of superglobal

  - by Prasoon Saurav

  I have been working on a Timesheet Management website. I have my home page as index.php //index.php <?php session_start(); if($_SESSION['logged']=='set') { $x=$_SESSION['username']; echo '<div align="right">'; echo 'Welcome ' .$x.'<br/>'; echo'<a href="logout.php" class="links">&nbsp;<b><u>Logout</u></b></a>' ; } else if($_SESSION['logged']='unset') { echo'<form id="searchform" method="post" action="processing.php"> <div> <div align="right"> Username&nbsp;<input type="text" name="username" id="s" size="15" value="" /> &nbsp;Password&nbsp;<input type="password" name="pass" id="s" size="15" value="" /> <input type="submit" name="submit" value="submit" /> </div> <br /> </div> </form> '; } ?> The problem I am facing is that during the first run of this script I get an error Notice: Undefined index: logged in C:\wamp\www\ps\index.php but after refreshing the page the error vanishes. How can I correct this problem? logged is a variable which helps determine whether the user is logged in or not. When the user is logged in $_SESSION['logged'] is set, otherwise unset. I want the default value of $_SESSION['logged'] to be unset prior to the execution of the script. How can I solve this problem?

• How to handle authenticated user access to resources in document oriented system?

  - by Jeremy Raymond

  I'm developing a document oriented application and need to manage user access to the documents. I have a module that handles user authentication, and another module that handles document CRUD operations on the data store. Once a user is authenticated I need to enforce what operations the user can and cannot perform to documents based upon the user's permissions. The best option I could think of to integrate these two pieces together would be to create another module that duplicates the data API but that also takes the authenticated user as a parameter. The module would delegate the authorization check to the auth module and delegate the document operation to the data access module. Something like: -module(auth_data_access). % User is authenticated (logged into the system) % save_doc validates if user is allowed to save the given document and if so % saves it returning ok, else returns {error, permission_denied} save_doc(Doc, User) -> case auth:save_allowed(Doc, User) of ok -> data_access:save_doc(Doc); denied -> {error, permission_denied} end end. Is there a better way I can handle this?

• A weird crash...

  - by Nima

  Hi, I have a piece of code that runs in debug mode in VS2008, C++. The problem is that when I am debugging the code line by line, at a very weird point of the code, it crashes and says: debug assertion faild. Expression: _BLOCK_TYPE_IS_VALID(pHead-nBlockUse) The crash point is on the first closed curly bracket (after mesh-edges[e].needsUpdate=false;) I don't understand why on a curly bracket? does that make sense to you guys? Can anybody help me understanding what is going on..? for(int e=0; e<mesh->edges.size(); e++) { if(mesh->edges[e].valid && mesh->edges[e].v[0]>=0 && mesh->edges[e].v[1]>=0 && mesh->points[mesh->edges[e].v[0]].writable && mesh->points[mesh->edges[e].v[1]].writable) { //update v_hat and its corresponding error DecEdge Current = DecEdge(e); pair<Point, float> ppf = computeVhat(e); Current.v_hat = ppf.first; Current.error = ppf.second; edgeSoup.push(Current); mesh->edges[e].needsUpdate=false; } }

• Return if remote stored procedure fails

  - by njk

  I am in the process of creating a stored procedure. This stored procedure runs local as well as external stored procedures. For simplicity, I'll call the local server [LOCAL] and the remote server [REMOTE]. USE [LOCAL] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER PROCEDURE [dbo].[monthlyRollUp] AS SET NOCOUNT, XACT_ABORT ON BEGIN TRY EXEC [REOMTE].[DB].[table].[sp] --This transaction should only begin if the remote procedure does not fail BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp1] COMMIT BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp2] COMMIT BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp3] COMMIT BEGIN TRAN EXEC [LOCAL].[DB].[table].[sp4] COMMIT END TRY BEGIN CATCH -- Insert error into log table INSERT INTO [dbo].[log_table] (stamp, errorNumber, errorSeverity, errorState, errorProcedure, errorLine, errorMessage) SELECT GETDATE(), ERROR_NUMBER(), ERROR_SEVERITY(), ERROR_STATE(), ERROR_PROCEDURE(), ERROR_LINE(), ERROR_MESSAGE() END CATCH GO When using a transaction on the remote procedure, it throws this error: OLE DB provider ... returned message "The partner transaction manager has disabled its support for remote/network transactions.". I get that I'm unable to run a transaction locally for a remote procedure. How can I ensure that the this procedure will exit and rollback if any part of the procedure fails?

• Strange FileNotFoundException occuring on production server in console application

  - by thmsn

  Hi I have an application that works fine in my dev enviroment, but throws weird errors in the production enviroment, I checked the version of .net on my dev machine aswell as the production server , they both run 3.5.30729.01. The exception I get is a System.IO.FileNotFoundException. StackTrace: at System.Diagnostics.FileVersionInfo.GetVersionInfo(String fileName) at System.Configuration.ClientConfigPaths.SetNamesAndVersion(String applicationFilename, Assembly exeAssembly, Boolean isHttp) at System.Configuration.ClientConfigPaths..ctor(String exePath, Boolean includeUserConfig) at System.Configuration.ClientConfigPaths.GetPaths(String exePath, Boolean includeUserConfig) at System.Configuration.ClientConfigurationHost.get_ConfigPaths() at System.Configuration.ClientConfigurationHost.RequireCompleteInit(IInternalConfigRecord record) at System.Configuration.BaseConfigurationRecord.GetSectionRecursive(String configKey, Boolean getLkg, Boolean checkPermission, Boolean getRuntimeObject, Boolean requestIsHere, Object& result, Object& resultRuntimeObject) at System.Configuration.BaseConfigurationRecord.GetSection(String configKey) at System.Configuration.ClientConfigurationSystem.System.Configuration.Internal.IInternalConfigSystem.GetSection(String sectionName) at System.Configuration.ConfigurationManager.GetSection(String sectionName) at System.Configuration.PrivilegedConfigurationManager.GetSection(String sectionName) at System.DirectoryServices.SearchResultCollection.ResultsEnumerator..ctor(SearchResultCollection results, String parentUserName, String parentPassword, AuthenticationTypes parentAuthenticationType) at System.DirectoryServices.SearchResultCollection.GetEnumerator() at System.DirectoryServices.DirectorySearcher.FindOne() Yesterday the error just went away, and today the error is occuring again. I tried using reflector and it appears to have something to do with config files or user config files. any ideas?
