  • when does factory girl create objects in db?

    - by Pavel K.
    i am trying to simulate a session using factory girl/shoulda (it worked with fixtures but i am having problems with using factories). i have following factories (user login and email both have 'unique' validations): Factory.define :user do |u| u.login 'quentin' u.email '[email protected]' end Factory.define :session_user, :class => Session do |u| u.association :user, :factory => :user u.session_id 'session_user' end and here's the test class MessagesControllerTest < ActionController::TestCase context "normal user" do setup do @request.session[:user_id]=Factory(:user).id @request.session[:session_id]=Factory(:session_user).session_id end should "be able to access new message creation" do get :new assert_response :success end end end but when i run "rake test:functionals", i get this test result 1) Error: test: normal user should be able to access new message creation. (MessagesControllerTest): ActiveRecord::RecordInvalid: Validation failed: Account name already exists!, Email already exists! which means that record already exists in db when i am referring to it in test setup. is there something i don't understand here? does factory girl create all factories in db on startup? rails 2.3.5/shoulda/factory girl

  • Flash video player doesn't play after rewriting a url

    - by Joel
    Hi! I recently started a new job working on a content management system. One of the jobs was to implement url rewriting, which i've done, but for some reason the URL rewriting has killed the ability to play flv files through FLVPlayer_Progressive. An example can be seen below: Working if you then follow the link on the menu and go to Campaigns It's a Living Thing you can see how it's not working when the url is being re-written. Below is the html for the object tag i'm setting within a gui editor on the admin side, everything on that end works also! <object height="160" width="284" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" id="FLVPlayer"> <param name="movie" value="/sitefiles/PeachSocial/flash/FLVPlayer_Progressive.swf"> <param name="salign" value="lt"> <param name="quality" value="high"> <param name="scale" value="noscale"> <param name="FlashVars" value="&amp;MM_ComponentVersion=1&amp;skinName=Clear_Skin_1&amp;autoPlay=true&amp;autoRewind=true&amp;streamName=/sitefiles/PeachSocial/flash/dept_envrnmnt"> <embed src="/sitefiles/PeachSocial/flash/FLVPlayer_Progressive.swf" flashvars="&amp;MM_ComponentVersion=1&amp;skinName=Clear_Skin_1&amp;autoPlay=true&amp;autoRewind=true&amp;streamName=/sitefiles/PeachSocial/flash/dept_envrnmnt" quality="high" scale="noscale" name="FLVPlayer" salign="LT" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash" width="284" height="160"> </object> I would have thought giving the path the way i am would have taken it back to the server root and gone from there, but it doesn't seem to like it once the url rewriting happens. Anyways i'm outta ideas after a pretty frustrating day of trying to pass the thing absolute urls, relative paths and the like and am hoping a fresh set of eyes may help.

  • How to specify selector when CAKeyframeAnimation is finished?

    - by darenchow
    I'm using a CAKeyframeAnimation to animate a view along a CGPath. When the animation is done, I'd like to be able to call some other method to perform another action. Is there a good way to do this? I've looked at using UIView's setAnimationDidStopSelector:, however from the docs this looks like it only applies when used within a UIView animation block (beginAnimations and commitAnimations). I also gave it a try just in case, but it doesn't seem to work. Here's some sample code (this is within a custom UIView sub-class method): // These have no effect since they're not in a UIView Animation Block [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)]; // Set up path movement CAKeyframeAnimation *pathAnimation = [CAKeyframeAnimation animationWithKeyPath:@"path"]; pathAnimation.calculationMode = kCAAnimationPaced; pathAnimation.fillMode = kCAFillModeForwards; pathAnimation.removedOnCompletion = NO; pathAnimation.duration = 1.0f; CGMutablePathRef path = CGPathCreateMutable(); CGPathMoveToPoint(path, NULL, self.center.x, self.center.y); // add all points to the path for (NSValue* value in myPoints) { CGPoint nextPoint = [value CGPointValue]; CGPathAddLineToPoint(path, NULL, nextPoint.x, nextPoint.y); } pathAnimation.path = path; CGPathRelease(path); [self.layer addAnimation:pathAnimation forKey:@"pathAnimation"]; A workaround I was considering that should work, but doesn't seem like the best way, is to use NSObject's performSelector:withObject:afterDelay:. As long as I set the delay equal to the duration of the animation, then it should be fine. Is there a better way? Thanks!

  • Forking in PHP on Windows

    - by Doug Kavendek
    We are running PHP on a Windows server (a source of many problems indeed, but migrating is not an option currently). There are a few points where a user-initiated action will need to kick off a few things that take a while and about which the user doesn't need to know if they succeed or fail, such as sending off an email or making sure some third-party accounts are updated. If I could just fork with pcntl_fork(), this would be very simple, but the PCNTL functions are not available in Windows. It seems the closest I can get is to do something of this nature: exec( 'php-cgi.exe somescript.php' ); However, this would be far more complicated. The actions I need to kick off rely on a lot of context that already will exist in the running process; to use the above example, I'd need to figure out the essential data and supply it to the new script in some way. If I could fork, it'd just be a matter of letting the parent process return early, leaving the child to work on a few more things. I've found a few people talking about their own work in getting various PCNTL functions compiled on Windows, but none seemed to have anything available (broken links, etc). Despite this question having practically the same name as mine, it seems the problem was more execution timeout than needing to fork. So, is my best option to just refactor a bit to deal with calling php-cgi, or are there other options? Edit: It seems exec() won't work for this, at least not without me figuring some other aspect of it, as it waits until the call returns. I figured I could use START, sort of like exec( 'start php-cgi.exe somescript.php' );, but it still waits until the other script finishes.

  • How to stop MVC caching the results of invoking and action method?

    - by Trey Carroll
    I am experiencing a problem with IE caching the results of an action method. Other articles I found were related to security and the [Authorize] attribute. This problem has nothing to do with security. This is a very simple "record a vote, grab the average, return the avg and the number of votes" method. The only slightly interesting thing about it is that it is invoked via Ajax and returns a Json object. I believe that it is the Json object that is getting catched. When I run it from FireFox and watch the XHR traffic with Firebug, everything works perfectly. However, under IE 8 the "throbber" graphic doesn't ever have time to show up and the page elements that display the "new" avg and count that are being injected into the page with jQuery are never different. I need a way to tell MVC to never cache this action method. This article seems to address the problem, but I cannot understand it: http://stackoverflow.com/questions/1441467/prevent-caching-of-attributes-in-asp-net-mvc-force-attribute-execution-every-tim I need a bit more context for the solution to understand how to extend AuthorizationAttribute. Please address your answer as if you were speaking to someone who lacks a deep understanding of MVC even if that means replying with an article on some basics/prerequisites that are required. Thanks, Trey Carroll

  • Cooperative/Non-preemptive threading avoiding threadlooks?

    - by Wayne
    Any creative ideas to avoid deadlocks on a yield or sleep with cooperative/non-preemptive multitasking without doing an O/S Thread.Sleep(10)? Typically the yield or sleep call will call back into the scheduler to run other tasks. But this can sometime produce deadlocks. Some background: This application has enormous need for speed and, so far, it's extremely fast as compared to other systems in the same industry. One of the speed techniques is cooperative/non-preemptive threading rather then the cost of a context switch from O/S threads. The high level design a priority manager which calls out to tasks depending on priority and processing time. Each task does one "iteration" of work and returns to wait its turn again in the priority queue. The tricky thing with non-preemptive threading is what to do when you want to a particular task to stop in the middle of work and wait for some other event from a different task before continuing. In this case, we have 3 tasks, A B and C where A is a controller that must synchronize the activity of B and C. First, A starts both B and C. Then B yields so C gets invoked. When C yields, A sees they are both inactive, decides it's time for B to run but not time for C yet. Well B is now stuck in a yield that has called C, so it can never run. Sincerely, Wayne

  • Calling SubmitChanges on DataContext does not update database.

    - by drasto
    In C# ASP.NET MVC application I use Link to SQL to provide data for my application. I have got simple database schema like this: In my controller class I reference this data context called Model (as you can see on the right side of picture in properties) like this: private Model model = new Model(); I've got a table (List) of Series rendered on my page. It renders properly and I was able to add delete functionality to delete Series like this: public ActionResult Delete(int id) { model.Series.DeleteOnSubmit(model.Series.SingleOrDefault(s => s.ID == id)); model.SubmitChanges(); return RedirectToAction("Index"); } Where appropriate action link looks like this: <%: Html.ActionLink("Delete", "Delete", new { id=item.ID })%> Also create (implemented in similar way) works fine. However edit does not work. My edit looks like this: public ActionResult Edit(int id) { return View(model.Series.SingleOrDefault(s => s.ID == id)); } [HttpPost] public ActionResult Edit(Series series) { if (ModelState.IsValid) { UpdateModel(series); series.Title = series.Title + " some string to ensure title has changed"; model.SubmitChanges(); return RedirectToAction("Index"); } I have controlled that my database has a primary key set up correctly. I debugged my application and found out that everything works as expected until the line with model.SubmitChanges();. This command does not apply the changes of Title property(or any other) against the database. Please help.

  • Changing text of TextView -- old text doesn't go away (Android 4.1.2)

    - by Jason Costabile
    I'm pretty new to Android development. Trying to accomplish something fairly simple -- change some displayed text when a timer ticks. Here's the potentially relevant code: CountDownTimer currentTimer; Resources res; TextView timerText; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_exercise); res = getResources(); timerText = (TextView) findViewById(R.id.timer_text); } @Override protected void onStart() { super.onStart(); //"Get ready" countdown currentTimer = new CountDownTimer(5000, 1000) { @Override public void onTick(long millisUntilFinished) { timerText.setText("" + (int)Math.ceil(millisUntilFinished / 1000.0)); } @Override public void onFinish() { ... } }; currentTimer.start(); } This works fine on an emulated 4.2.2 device, but on a 4.1.2 device (both physical and emulated), the changed TextView appears as such while the countdown proceeds: If you can't tell, that's the numbers 5,4,3 overlayed. So, when I set a new string for the TextView, the new string is displayed but without replacing the old string. Any other TextViews used in my app behave in the same way. Any ideas what the problem is and how to fix it? Edit: From the XML layout file: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" tools:context=".ExerciseActivity" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:keepScreenOn="true" android:orientation="vertical" > ... <TextView android:id="@+id/timer_text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:textIsSelectable="false" android:hint="@string/timer_default" /> ... </LinearLayout> That's all that could be relevant.

  • Empty POST from jQuery UI Dialog to PHP function with $.post

    - by solefald
    Hello, I am having hell of a time trying to figure this one out. Maybe someone can help me here or point me in the right direction. I have a jQuery UI dialog that pops up when user clicks on an image. The dialog displays a form with 2 drop down windows. "dept" and "group". Group drop down is disabled, until something is selected in the "dept" dropdown menu. When user selects a department, I do a POST to php function and then enable and populate the group drop down. Simple enough... <select name="dept" id="dept_select" onchange="getDeptGroups(this.value);"> // Some data here </select> JS function: function getDeptGroups(dept) { // This alert works and displays department name. //alert(dept); $.post("/am/ldap/getDepartmentGroups.php", { department: dept }, function(data){ alert(data); }); } and finally in php page i just do <? print_r($_POST); ?> and end up with empty array. Array ( ) This happens in both, Chrome and Firefox, however, FireBug clearly shows post data being submitted: What am i doing wrong here?

  • Parent Control Mouse Enter/Leave Events With Child Controls

    - by Paul Williams
    I have a C# .NET 2.0 WinForms app. My app has a control that is a container for two child controls: a label, and some kind of edit control. You can think of it like this, where the outer box is the parent control: +---------------------------------+ | [Label Control] [Edit Control] | +---------------------------------+ I am trying to do something when the mouse enters or leaves the parent control, but I don't care if the mouse moves into one of its children. I want a single flag to represent "the mouse is somewhere inside the parent or children" and "the mouse has moved outside of the parent control bounds". I've tried handling MouseEnter and MouseLeave on the parent and both child controls, but this means the action begins and ends multiple times as the mouse moves across the control. In other words, I get this: Parent.OnMouseEnter (start doing something) Parent.OnMouseLeave (stop) Child.OnMouseEnter (start doing something) Child.OnMouseLeave (stop) Parent.OnMouseEnter (start doing something) Parent.OnMouseLeave (stop) The intermediate OnMouseLeave events cause some undesired effects as whatever I'm doing gets started and then stopped. I want to avoid that. I don't want to capture the mouse as the parent gets the mouse over, because the child controls need their mouse events, and I want menu and other shortcut keys to work. Is there a way to do this inside the .NET framework? Or do I need to use a Windows mouse hook?

  • Extend base type and automatically update audit information on Entity

    - by Nix
    I have an entity model that has audit information on every table (50+ tables) CreateDate CreateUser UpdateDate UpdateUser Currently we are programatically updating audit information. Ex: if(changed){ entity.UpdatedOn = DateTime.Now; entity.UpdatedBy = Environment.UserName; context.SaveChanges(); } But I am looking for a more automated solution. During save changes, if an entity is created/updated I would like to automatically update these fields before sending them to the database for storage. Any suggestion on how i could do this? I would prefer to not do any reflection, so using a text template is not out of the question. A solution has been proposed to override SaveChanges and do it there, but in order to achieve this i would either have to use reflection (in which I don't want to do ) or derive a base class. Assuming i go down this route how would I achieve this? For example EXAMPLE_DB_TABLE CODE NAME --Audit Tables CREATE_DATE CREATE_USER UPDATE_DATE UPDATE_USER And if i create a base class public abstract class IUpdatable{ public virtual DateTime CreateDate {set;} public virtual string CreateUser { set;} public virtual DateTime UpdateDate { set;} public virtual string UpdateUser { set;} } The end goal is to be able to do something like... public overrride void SaveChanges(){ //Go through state manager and update audit infromation //FOREACH changed entity in state manager if(entity is IUpdatable){ //If state is created... update create audit. //if state is updated... update update audit } } But I am not sure how I go about generating the code that would extend the interface.

  • How best to embed multiple Flash Player instances using swfobject via a usercontrol?

    - by panamack
    I have a ListView on a Page within a MasterPage and some very ugly ugly autogenerated IDs. Such as..."ctl00_workbenchPlaceHolder_ListView1_ctrl1_LibItem2One" Using swfobject.embedSWF(...) requires me to hand over the id of a div on my page that can be replaced with object/embed markup depending on the browser context. My aim is to show the user a collection of video's they have uploaded to their website so they can review them and change some related data if desired. Hence the ListView which is populated via a SQLDataSource which currently provides a number of URLs pointing to .flv files. But it ain't gonna work if I put a <div id="replaceme"></div>' in my user control because I may then have more than one id="replaceme" and poor swfobject won't like it. So my evil solution is to put an <asp:Literal> in my usercontrol and build the script, function name and div tag id as a string. ApplyVideoConfiguration is called if the library object retreived from the database is a video and switches to the relevant View of a MultiView control. protected void ApplyVideoConfiguration() { MultiViewLibItem.ActiveViewIndex = 3; string functionName = "MakeFlashFor_" + this.ClientID; string divId = "fp" + this.ClientID; VideoScriptLiteral.Text = "<script type=\"text/javascript\">" + "Sys.Application.add_load(" + functionName + ");" + "function " + functionName + "(){" + "swfobject.embedSWF('PanamaVideoThumbnail.swf', '" + divId + "', '140', '127', '10');" + "};" + "</script>" + "<div id=\"" + divId + "\" ></div>" ; } I was wondering, just how bad a solution is this, I'm really completely inexperienced when it comes to best practices but my instincts are telling me this is bad, although it does succeed in the aim of embedding some Flash Player instances. Can anyone help me make it beautiful?

  • Choosing an installer product that is free and will download/install the .NET Framework

    - by Coder7862396
    I'm currently using the Visual Studio Installer (Setup Project) in Visual Studio 2010 as the installer for MyProgram. It has some quirky bugs and is not very customizable so I would like to switch to another installer product. Here are my requirements: Must be free (and licensed for commercial use) Must install the Windows Installer 3.1 and .NET Framework 4.0 if the client doesn't have them The installer will download them if they are not available The code for detecting the .NET Framework and downloading it must be written by Microsoft (I do not want to have to update hard-coded URLs and registry keys in the future). I know that the Windows SDK includes a setup bootstrap that does this (C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper) In the future, when .NET Framework 5 is released and MyProgram uses it, no installer code will need to be changed, the updated installer product should see that MyProgram now uses the .NET Framework version 5 and will install that Here are my current choices: Visual Studio Installer: Automatically detects/downloads/installs Windows Installer and .NET Framework using a bootstrapper Setup.exe (Good!) Limited/buggy functionality (Uninstall shortcuts in the Start Menu cause empty folders to be left behind during uninstall, asking the user if they want a desktop shortcut requires a lot of work, etc.) NSIS: Doesn't natively support the .NET Framework so adding it as a prerequisite requires excessive coding, hardcoded URLS, etc. Inno Setup: Doesn't natively support the .NET Framework so adding it as a prerequisite requires excessive coding, hardcoded URLs, etc. WiX: Steep learning curve... not sure if I want to spend weeks learning it only to find out that it has the same uninstall problem as the Visual Studio Installer (because they both use MSI files) InstallShield LE 2010: Downloading it requires me to setup a fake email account to register just to download it. Then once it is installed it has to contact the company's servers and transmit some private information to them before I'm even allowed to try the free version. This is the most insidious form of DRM that there is and I will not accept it.

  • Should programmers do Pro Bono work? where are the code public defenders?

    - by Tj Kellie
    How many projects are people doing based on the Bro Bono publico ideals versus working for the highest wage or potential for a cash-in-buy-out payday? For years lawyers have been called out for excessive gathering of wealth from high bill rates and huge settlement deals, hiring out their knowledge and skills to the highest bidders. People call for them to do more for free, use the laws and their time to defend or further some cause thats in the public's best interest. Is professional software development that different? So many bright people and so much knowledge of complex systems. Do you think that there is enough of a "Pro Bono" movement to solve the social and public problems in the industry right now? If so what are the examples to point to? OLPC? NOTE: Saying that open source software is the same as pro bono misses the point completely. I was looking for specific projects with a social context, not just group-sourcing for free software. Just because your not making anyone pay for your software does not mean its doing anyone any good. I'm not calling out manual enforcement of pro bono work for programmers, really just want some objective opinions and concrete examples of social-minded software/tech development projects like the One Laptop Per Child project. I'm sure open source would be a natural tie-in for some.

  • Namespace Problem

    - by Tarik
    Hello, Normally we all do use using System.Linq; and using System.Data.Linq; for example on the code-behind and expect we can reach the members of these namespaces from Source Code like <%= Something.First()%> but when I wrote it, asp.net said it couldn't find First() in the context and I had to add <%@ Import Namespace="System.Linq" which looked very weird to me but it worked out. Since they are targeting at the same class why they both need separate namespace importing. Code-behind : using System; using System.Data.Linq; using System.Linq; using System.Text namespace Something { class Items : System.Web.UI { //... } } but also I need to add the same Linq namespace on the Html Source part <%@Import Namespace="System.Linq"%> Do I know something wrong or this is some kind of bug in asp.net. I thought when the page is compiling, asp.net combines these two classes and converts html source code into cs class and indicates the control in Control c= new Control(); hierarchy. Thanks in advance.

  • In Seam what's the difference between injected EntityManager and getEntityManager from EntityHome

    - by Navi
    I am testing a Seam application using the needle test API. In my code I am using the getEntityManager() method from EntityHome. When I run the unit tests against an in memory database I get the following exception: java.lang.IllegalStateException: No application context active at org.jboss.seam.Component.forName(Component.java:1945) at org.jboss.seam.Component.getInstance(Component.java:2005) at org.jboss.seam.Component.getInstance(Component.java:1983) at org.jboss.seam.Component.getInstance(Component.java:1977) at org.jboss.seam.Component.getInstance(Component.java:1972) at org.jboss.seam.framework.Controller.getComponentInstance(Controller.java:272) at org.jboss.seam.framework.PersistenceController.getPersistenceContext(PersistenceController.java:20) at org.jboss.seam.framework.EntityHome.getEntityManager(EntityHome.java:177) etc .. I can resolve some of these errors by injecting the EntityManager with @In EntityManager entityManager; Unfortunately the persist method of EntityHome also calls the getEntityManager. This means a lot of mocks or rewriting the code somehow. Is there any workaround and why is this exception thrown anyway? I am using Seam 2.2.0 GA by the way. There is nothing special about the components. They are generated by seam-gen. The test is performed with in memory database - I followed the examples in http://jbosscc-needle.sourceforge.net/jbosscc-needle/1.0/db-util.html.

  • MissingMethodException thrown when calling new form in Compact Framework

    - by Boerema
    I'm updating an old mobile device application for better flexibility. I had basically added the ability to configure the address of our SQL server in the case that we want to use our test server as opposed to our production server. I don't think this is causing the problem, but I wanted to state it. I also upgraded the project from a VS 2000 project to a VS 2005 project. The issue I am having is that when I try to run the program in the VS emulator for Pocket PC, I get an error. It occurs after our "main menu" form loads and the user selects the next form to load. The form is initialized without issue, but when we try to run the .ShowDialog() method, it throws a System.MissingMethodException. I don't have a lot of experience with the Compact Framework and really have no idea where to start looking for problems. I stepped the debugger through the entire initializing process for the new form and it ran without issue. But, again, when we come to the ShowDialog call, it throws the error. Any ideas in where to start looking or known issues would be greatly appreciated.

    I have installed subclipse, Ant, IvyDE, Red5 Plugin for eclipse, All of the Environmental variables are set and the necessary elements have been added to the path. I am attempting to create a Red5 Distribution by using eclipse, opening Build.xml right clicking dist [default] in the outline window and running as and selecting Ant Builder. Eclipse says that the build is Successful. I first stop the Red5 Service, and then I attempt to run the build I create in eclipse it fails, below are the errors that display in the command prompt. I was hoping someone else might have run into a similar issue before. Starting Red5 Red5 root: C:/Users/Admin/workspace/temp/red5_server/dist Configuation root: C:/Users/Admin/workspace/temp/red5_server/dist/conf Setting temp directory to C:\Users\Admin\AppData\localLow Exception in thread "main" java.lang.Error: Unresolved compilation problems: The import org.slf4j.bridge cannot be resolved The import org.springframework.context.support.FileSystemXmlApplicationC ontext cannot be resolved SLF4JBridgeHandler cannot be resolved FileSystemXmlApplicationContext cannot be resolved to a type FileSystemXmlApplicationContext cannot be resolved to a type at org.red5.server.Launcher.<init>(Launcher.java:25) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstruct orAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingC onstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) at java.lang.Class.newInstance0(Class.java:355) at java.lang.Class.newInstance(Class.java:308) at org.red5.server.Bootstrap.bootStrap(Bootstrap.java:132) at org.red5.server.Bootstrap.main(Bootstrap.java:50) Press any key to continue . . .

  • Strange activity stack behavior when using MapActivity

    - by AndroidDev
    I have the following activity structure in my application A simple "splash screen" activity is started when the application is fired up (let's call it "Splash"). This activity starts the main activity when the user presses a button (I will call it "Main"). Main can in turn start two activities from the menu. The first activity presents a simple form (let's call this one "Form"), the second is a MapActivity that presents a map (it is called "Map"). Main, Form, and Map are declared exactly the same in the manifest: <activity android:name="fully qualified activity class" android:screenOrientation="landscape" android:configChanges="keyboard|keyboardHidden|orientation" > <intent-filter> <action android:name="android.intent.action.DEFAULT" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> When Main is active and I start Form and press "back", Main comes up again. Pressing "back" again brings up "Splash". Nothing strange here. Now comes the strange part: when I am in Main, start Map, and press "back", Main comes up as expected. But pressing "back" again just restarts Main. A second press on "back" is needed to bring me back to Splash! So it seems that starting the Map activity somehow results in Main ending up on the activity stack twice while starting the Form activity does not! Both Form and Map are started like this: startActivity(new Intent(this, MyActivity.class)); I don not catch the back key in any activity. Any clues on what is going on or how to debug this?

  • Entity framework entity class mapping with plain .net class

    - by Elan
    I have following in entity framework Table - Country Fields List item Country_ID Dialing_Code ISO_Alpha2 ISO_Alpha3 ISO_Full I would like to map only selected fields from this entity model to my domain class. My domain model class is public class DomainCountry { public int Country_ID { get; set; } public string Dialing_Code { get; set; } public string ISO_3166_1_Alpha_2 { get; set; } } The following will work however insert or update is not possible. In order to get insert or update we need to use ObjectSet< but it will not support in my case. IQueryable<DomainCountry> countries = context.Countries.Select( c => new DomainCountry { Country_ID = c.Country_Id, Dialing_Code = c.Dialing_Code, ISO_3166_1_Alpha_2 = c.ISO_3166_1_Alpha_2 }); It will be really fantastic could someone provide a nice solution for this. Ideally it will be kind of proxy class which will support all the futures however highly customizable i.e. only the columns we want to expose to the outer world

  • Cocoa Core data: cannot save Created Items in NSTableview

    - by Paul Rostorp
    Hello, I'm am a beginner in mac os x development and am trying to get started with all this. Here is my problem : I've create a non-document based cocoa app using core data as storage. I've added an entity and attributes to the xdatamodel. In IB i've created an NSArrayController and linked it properly. I've created an nstableview binded to the nsarraycontroller. Next I added a button linked to nsarraycontroller with the " add: " method. When I try it out, I can add and edit the items in the table. Here comes the problem: Core data is supposed to save everything automatically, but to make sure i linked the "save" button in the menu to the appdelegate and to the " file's owner" , first responder, application... everything possible ( with both " save :" and " saveaction:" methods ). And still it doesn't save when clicking save: when I restart the cell created ( and renamed ) are gone. And also, I didn't even edit the source code yet; core data for such simple tasks is supposed to only need Interface builder. Please help me for this, I haven't found any threads resolving this problem. Thank you in advance.

  • Can someone describe the nested set model from a C#/LINQ perspective?

    - by Chad
    I know the nested set model doesn't pertain to the C# language or LINQ directly... it's what I'm using to develop my web app. For hierarchical data (categories with sub-categories in my case), I'm currently using something similar to the Adjacency List model. At the moment, I've only got 2 levels of categories, but I'd like to take it further and allow for n levels of categories using the nested set model. I'm not quite clear on how to use it in a C# context. Here's the article I'm reading on the nested set model. Though this article cleared up my confusion some, I still have a big ?? in my head: - Is inserting, updating or deleting categories tedious? It looks like the left and right numbers would require re-numbering... what would the LINQ queries look like for the following scenarios? Delete a child node (re-number all node's left/right values) Delete a parent node (what do you do with the orphans?) Move a child node to a different parent node (renumber again) If my understanding is correct, at all times the child node's left/right values will always be between the parent node's left/right values, am I correct? Seems easy enough, if only the categories were static... most likely I need to spend more time to get my head around the concept. Any help is greatly appreciated!

  • How does VS 2005 provide history across all TFS Team Projects when tf.exe cannot?

    - by AakashM
    In Visual Studio 2005, in the TFS Source Control Explorer, these is a top-level node for the TFS Server itself, with a child node for each Team Project. Right-clicking either the server node or the node for a Team Project gives a context menu on which there is a View History item. Selecting this gives you a History window showing the last 200 or so changesets, either for the specific Team Project chosen, or across all Team Projects. It is this history across all Team Projects that I am wondering about. The command-line tf.exe history command provides (as I understand it) basically the same functionality as is provided by the VS TFS Source Control plug-in. But I cannot work out how to get tf.exe history to provide this across-all-Team-Projects history. At a command line, supposing I have C:\ mapped as the root of my workspace, and Foo, Bar, and Baz as Team Projects, I can do C:\> tf history Foo /recursive /stopafter:200 to get the last 200 changesets that affected Team Project Foo; or from within a Team Project folder C:\Bar> tf history *.* /recursive /stopafter:200 which does the same thing for Team Project Bar - note that the wildcard *.* is allowed here. However, none of these work (each gives the error message shown): C:\> tf history /recursive /stopafter:200 The history command takes exactly one item C:\> tf history *.* /recursive /stopafter:200 Unable to determine the source control server C:\> tf history *.* /server:servername /recursive /stopafter:200 Unable to determine the workspace I don't see an option in the docs for tf for specifying a workspace; it seems to only want to determine it from the current folder. So what is VS 2005 doing? Is it internally doing a history on each Team Project in turn and then sticking the results together?? note also that I have tried with Power Tools; tfpt history from the command line gives exactly the same error messages seen here
