Matlab matrix replacement assignment gives error

- by Gulcan

Hello, when i tried to update some part of a matrix, i got the following error message: ??? Assignment has fewer non-singleton rhs dimensions than non-singleton subscripts My code tries to update some values of a matrix that represent a binary image. My code is as follows: outImage(3:5,2:4,1) = max(imBinary(3:5,2:4,1)); When I delete last parameter (1), this time I get the same error. I guess there is a mismatch between dimensions but I could not get it. outImage is a new object that is created at that time (I tried to create it before, but nothing changed). What may be wrong? Thanks in advance, Gulcan

Automating HP Quality Center with Python or Java

- by Hari

Hi, We have a project that uses HP Quality Center and one of the regular issues we face is people not updating comments on the defect. So I was thinkingif we could come up with a small script or tool that could be used to periodically throw up a reminder and force the user to update the comments. I came across the Open Test Architecture API and was wondering if there are any good Python or java examples for the same that I could see. Thanks Hari

Memory leak involving jQuery Ajax requests

- by Eli Courtwright

I have a webpage that's leaking memory in both IE8 and Firefox; the memory usage displayed in the Windows Process Explorer just keeps growing over time. The following page requests the "unplanned.json" url, which is a static file that never changes (though I do set my Cache-control HTTP header to no-cache to make sure that the Ajax request always goes through). When it gets the results, it clears out an HTML table, loops over the json array it got back from the server, and dynamically adds a row to an HTML table for each entry in the array. Then it waits 2 seconds and repeats this process. Here's the entire webpage: <html> <head> <title>Test Page</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> </head> <body> <script type="text/javascript"> function kickoff() { $.getJSON("unplanned.json", resetTable); } function resetTable(rows) { $("#content tbody").empty(); for(var i=0; i<rows.length; i++) { $("<tr>" + "<td>" + rows[i].mpe_name + "</td>" + "<td>" + rows[i].bin + "</td>" + "<td>" + rows[i].request_time + "</td>" + "<td>" + rows[i].filtered_delta + "</td>" + "<td>" + rows[i].failed_delta + "</td>" + "</tr>").appendTo("#content tbody"); } setTimeout(kickoff, 2000); } $(kickoff); </script> <table id="content" border="1" style="width:100% ; text-align:center"> <thead><tr> <th>MPE</th> <th>Bin</th> <th>When</th> <th>Filtered</th> <th>Failed</th> </tr></thead> <tbody></tbody> </table> </body> </html> If it helps, here's an example of the json I'm sending back (it's this exact array wuith thousands of entries instead of just one): [ { mpe_name: "DBOSS-995", request_time: "09/18/2009 11:51:06", bin: 4, filtered_delta: 1, failed_delta: 1 } ] EDIT: I've accepted Toran's extremely helpful answer, but I feel I should post some additional code, since his removefromdom jQuery plugin has some limitations: It only removes individual elements. So you can't give it a query like `$("#content tbody tr")` and expect it to remove all of the elements you've specified. Any element that you remove with it must have an `id` attribute. So if I want to remove my `tbody`, then I must assign an `id` to my `tbody` tag or else it will give an error. It removes the element itself and all of its descendants, so if you simply want to empty that element then you'll have to re-create it afterwards (or modify the plugin to empty instead of remove). So here's my page above modified to use Toran's plugin. For the sake of simplicity I didn't apply any of the general performance advice offered by Peter. Here's the page which now no longer memory leaks: <html> <head> <title>Test Page</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> </head> <body> <script type="text/javascript">  </script> <div id="message" style="color:red"></div> <table id="content" border="1" style="width:100% ; text-align:center"> <thead><tr> <th>MPE</th> <th>Bin</th> <th>When</th> <th>Filtered</th> <th>Failed</th> </tr></thead> <tbody id="id_field_required"></tbody> </table> </body> </html> FURTHER EDIT: I'll leave my question unchanged, though it's worth noting that this memory leak has nothing to do with Ajax. In fact, the following code would memory leak just the same and be just as easily solved with Toran's removefromdom jQuery plugin: function resetTable() { $("#content tbody").empty(); for(var i=0; i<1000; i++) { $("#content tbody").append("<tr><td>" + "DBOSS-095" + "</td>" + "<td>" + 4 + "</td>" + "<td>" + "09/18/2009 11:51:06" + "</td>" + "<td>" + 1 + "</td>" + "<td>" + 1 + "</td></tr>"); } setTimeout(resetTable, 2000); } $(resetTable);

WPF, PreviewKeyDown event and underscore char

- by commanderz

Hi, I'm catching key hits with PreviewKeyDown event in my WPF component. I need to distinguish characters being typed: letters vs. numbers vs. underscore vs. anything else. Letters and numbers work fine (just convert the Key property of the KeyEventArgs object to string and work with character 0 of that string), but this won't work for underscore. It's ToString value depends on localized keyboard settings (it shows up as "OemMinus" on EN/US keyboard and "OemQuestion" on CZ/QWERTY keyboard). So how can I RELIABLY find out, if the typed char is underscore in the PreviewKeyDown event? Thanks for any help

I use the ddwrt:FormatDateTime function to format the output like yyyyMMdd. inputs like 01/01/2010 work fine but when the day gets over the number 12 the output is an emtpy string. ddwrt:FormatDate(string(@myDate), 1033, 'yyyyMMdd') At first I thought it could be a language specific problem but even none of those combinations work: 13/01/2010 01/13/2010 13.01.2010

ApplyCurrentValues in EF 4

- by ali62b

I just was playing with EF 4 in VS 2010 RC and just found that ApplyCurrentValues dont work when the Property is of type bool and the newly value is false !!!??? and it works when the newly value is true . I dont know if this is a bug or I'm missing something but I just work with a very ugly work around : public void UpdateProduct(Product updatedProduct) { using (model) { model.Products.Attach(new Product { ProductID = updatedProduct.ProductID }); model.Products.ApplyCurrentValues(updatedProduct); Product originalProduct = model.Products.Single(p => p.ProductID == updatedProduct.ProductID); originalProduct.Discontinued = updatedProduct.Discontinued; model.SaveChanges(); } } any idea or better work around?

Can I read an Outlook (2003/2007) PST file in C#?

- by Andy May

Is it possible to read a .PST file using C#? I would like to do this as a standalone application, not as an Outlook addin (if that is possible). If have seen other SO questions similar to this mention MailNavigator but I am looking to do this programmatically in C#. I have looked at the Microsoft.Office.Interop.Outlook namespace but that appears to be just for Outlook addins. LibPST appears to be able to read PST files, but this is in C (sorry Joel, I didn't learn C before graduating). Any help would be greatly appreciated, thanks! EDIT: Thank you all for the responses! I accepted Matthew Ruston's response as the answer because it ultimately led me to the code I was looking for. Here is a simple example of what I got to work (You will need to add a reference to Microsoft.Office.Interop.Outlook): using System; using System.Collections.Generic; using Microsoft.Office.Interop.Outlook; namespace PSTReader { class Program { static void Main () { try { IEnumerable<MailItem> mailItems = readPst(@"C:\temp\PST\Test.pst", "Test PST"); foreach (MailItem mailItem in mailItems) { Console.WriteLine(mailItem.SenderName + " - " + mailItem.Subject); } } catch (System.Exception ex) { Console.WriteLine(ex.Message); } Console.ReadLine(); } private static IEnumerable<MailItem> readPst(string pstFilePath, string pstName) { List<MailItem> mailItems = new List<MailItem>(); Application app = new Application(); NameSpace outlookNs = app.GetNamespace("MAPI"); // Add PST file (Outlook Data File) to Default Profile outlookNs.AddStore(pstFilePath); MAPIFolder rootFolder = outlookNs.Stores[pstName].GetRootFolder(); // Traverse through all folders in the PST file // TODO: This is not recursive, refactor Folders subFolders = rootFolder.Folders; foreach (Folder folder in subFolders) { Items items = folder.Items; foreach (object item in items) { if (item is MailItem) { MailItem mailItem = item as MailItem; mailItems.Add(mailItem); } } } // Remove PST file from Default Profile outlookNs.RemoveStore(rootFolder); return mailItems; } } } Note: This code assumes that Outlook is installed and already configured for the current user. It uses the Default Profile (you can edit the default profile by going to Mail in the Control Panel). One major improvement on this code would be to create a temporary profile to use instead of the Default, then destroy it once completed.

IntelliJ 12 - Grails Distribution in specified path is broken

- by Prayag Upd

I am struggling to configure grails 2.3.X in IntelliJ idea 12. Grails 2.2.X is configured successfully. Grails 2.3.2 is working properly from terminal. I can compile, test, run my application. But while trying to configure it in IntelliJ so that dependencies get resolved, I get the IntelliJ shouting straight to me(as pictured below). Looks like Grails Distribution in specified path is broken. Cannot determinate version. What I see is changes in grails-2.3.x/dist/ to earlier version's grails-2.2.x/dist/. Is this because there's no support for newer version(2.3.x) of grails in IntelliJ 12 or what ? I want nothing else but my application (jar) dependencies to be resolved in the IDE.

user input of one php script pass to another php without modification in first php script

- by ish12

hi all.. Consider two php scripts(o.php & t.php) o.php contains both html and php. html here gets user input for eg:user name and password this information is passed to php using php-self. I want the user input of o.php passed to t.php without any modification in o.php. I ve used include and require in the t.php but the problem is it displays the output of o.php but i need only the user input values from o.php without displaying the output of o.php. Using functions or session in o.php we can pass user input but am in the situation tat i should not add or modify o.php. thanks in advance!!

How to test Rails 3 Engines with Cucumber & Rspec?

- by cowboycoded

I apologize if this question is slightly subjective... I am trying to figure out the best way to test Rails 3 Engines with Cucumber & Rspec. In order to test the engine a rails 3 app is necessary. Here is what I am currently doing: Add a rails test app to the root of the gem (myengine) by running: rails new /myengine/rails_app Add Cucumber to /myengine/rails_app/features as you would in a normal Rails app Require the Rails Engine Gem (using :path=>"/myengine") in /myengine/rails_app/Gemfile Add spec to the root directory of the gem: /myengine/spec Include the fixtures in /myengine/spec/fixtures and I add the following to my cuc env.rb: env.rb: Fixtures.reset_cache fixtures_folder = File.join(Rails.root, 'spec', 'fixtures') fixtures = Dir[File.join(fixtures_folder, '*.yml')].map {|f| File.basename(f, '.yml') } Fixtures.create_fixtures(fixtures_folder, fixtures) Do you see any problems with setting it up like this? The tests run fine, but I am a bit hesitant to put the features inside the test rails app. I originally tried putting the features in the root of the gem and I created the test rails app inside features/support, but for some reason my engine would not initialize when I ran the tests, even though I could see the app loading everything else when cuc ran. If anyone is working with Rails Engines and is using cuc and rspec for testing, I would be interested to hear your setup.

What does 'useLegacyV2RuntimeActivationPolicy' do in the .NET 4 config?

- by Cameron MacFarland

While converting a project that used SlimDX, and therefore has unmanaged code, to .NET 4.0 I ran into the following error: Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information. Googling around gave me the solution, which is to add this to the applications config: <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup> </configuration> My question is, what is the useLegacyV2RuntimeActivationPolicy doing? I can't find any documentation about it.

Getting an ASP.MVC2/VS2010 application to work in IIS 7.5

- by Jeroen-bart Engelen

I've recently downloaded beta 2 of VS2010 and started playing with ASP.NET MVC2. Initial development was done with Casini, but now I wanted to run the application from IIS 7.5 (I'm running Windows 7). I've installed the IIS6 metabase compatiblity and I run VS2010 as administrator so I can use the "Create Virtual Directory" button from the "Web" tab of the project settings. This created the web application entry in IIS, but it doesn't work. When I go to the main page (http://localhost/MyMvcApp/) I get a HTTP 403 error. When I go directly to one of the sub-pages (http://localhost/MyMvcApp/Home/) I get an HTTP 404. So I guess for some reason the URL routing isn't working. I've already added UrlRouting as a module and a handler to the web.config. In my searches this is offered as a solution for some similair problems. But for me this still doesn't work. The interesting part of my web.config looke like this: <system.web> <compilation debug="true" targetFramework="4.0"> <assemblies> <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </assemblies> </compilation> <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" timeout="2880" /> </authentication> <membership> <providers> <clear /> <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" /> </providers> </membership> <profile> <providers> <clear /> <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/" /> </providers> </profile> <roleManager enabled="false"> <providers> <clear /> <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/" /> <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/" /> </providers> </roleManager> <pages> <namespaces> <add namespace="System.Web.Mvc" /> <add namespace="System.Web.Mvc.Ajax" /> <add namespace="System.Web.Mvc.Html" /> <add namespace="System.Web.Routing" /> </namespaces> </pages> <httpHandlers> <add verb="*" path="*.mvc" validate="false" type="System.Web.Mvc.MvcHttpHandler" /> </httpHandlers> <customErrors mode="Off" /> </system.web> <system.webServer> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true" > <remove name="UrlRoutingModule"/> <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </modules> <handlers> <remove name="MvcHttpHandler" /> <add name="MvcHttpHandler" preCondition="integratedMode" verb="*" path="*.mvc" type="System.Web.Mvc.MvcHttpHandler" /> <add name="UrlRoutingHandler" preCondition="integratedMode" verb="*" path="UrlRouting.axd" type="System.Web.HttpForbiddenHandler, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </handlers> <httpErrors errorMode="Detailed" /> </system.webServer>

C# .Net 3.5 Asynchronous Socket Server Performance Problem

- by iBrAaAa

I'm developing an Asynchronous Game Server using .Net Socket Asynchronous Model( BeginAccept/EndAccept...etc.) The problem I'm facing is described like that: When I have only one client connected, the server response time is very fast but once a second client connects, the server response time increases too much. I've measured the time from a client sends a message to the server until it gets the reply in both cases. I found that the average time in case of one client is about 17ms and in case of 2 clients about 280ms!!! What I really see is that: When 2 clients are connected and only one of them is moving(i.e. requesting service from the server) it is equivalently equal to the case when only one client is connected(i.e. fast response). However, when the 2 clients move at the same time(i.e. requests service from the server at the same time) their motion becomes very slow (as if the server replies each one of them in order i.e. not simultaneously). Basically, what I am doing is that: When a client requests a permission for motion from the server and the server grants him the request, the server then broadcasts the new position of the client to all the players. So if two clients are moving in the same time, the server is eventually trying to broadcast to both clients the new position of each of them at the same time. EX: Client1 asks to go to position (2,2) Client2 asks to go to position (5,5) Server sends to each of Client1 & Client2 the same two messages: message1: "Client1 at (2,2)" message2: "Client2 at (5,5)" I believe that the problem comes from the fact that Socket class is thread safe according MSDN documentation http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.aspx. (NOT SURE THAT IT IS THE PROBLEM) Below is the code for the server: /// /// This class is responsible for handling packet receiving and sending /// public class NetworkManager { /// /// An integer to hold the server port number to be used for the connections. Its default value is 5000. /// private readonly int port = 5000; /// /// hashtable contain all the clients connected to the server. /// key: player Id /// value: socket /// private readonly Hashtable connectedClients = new Hashtable();

Troubleshooting .NET "Fatal Execution Engine Error"

- by JYelton

Summary: I periodically get a .NET Fatal Execution Engine Error on an application which I cannot seem to debug. The dialog that comes up only offers to close the program or send information about the error to Microsoft. I've tried looking at the more detailed information but I don't know how to make use of it. Error: The error is visible in Event Viewer under Applications and is as follows: .NET Runtime version 2.0.50727.3607 - Fatal Execution Engine Error (7A09795E) (80131506) The computer running it is Windows XP Professional SP 3. (Intel Core2Quad Q6600 2.4GHz w/ 2.0 GB of RAM) Other .NET-based projects that lack multi-threaded downloading (see below) seem to run just fine. Application: The application is written in C#/.NET 3.5 using VS2008, and installed via a setup project. The app is multi-threaded and downloads data from multiple web servers using System.Net.HttpWebRequest and its methods. I've determined that the .NET error has something to do with either threading or HttpWebRequest but I haven't been able to get any closer as this particular error seems impossible to debug. I've tried handling errors on many levels, including the following in Program.cs: // handle UI thread exceptions Application.ThreadException += new ThreadExceptionEventHandler(Application_ThreadException); // handle non-UI thread exceptions AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); Application.EnableVisualStyles(); Application.SetCompatibleTextRenderingDefault(false); // force all windows forms errors to go through our handler Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException); More Notes and What I've Tried... Installed Visual Studio 2008 on the target machine and tried running in debug mode, but the error still occurs, with no hint as to where in source code it occurred. When running the program from its installed version (Release) the error occurs more frequently, usually within minutes of launching the application. When running the program in debug mode inside of VS2008, it can run for hours or days before generating the error. Reinstalled .NET 3.5 and made sure all updates are applied. Broke random cubicle objects in frustration. Rewritten parts of code that deal with threading and downloading in attempts to catch and log exceptions, though logging seemed to aggravate the problem (and never provided any data). Question: What steps can I take to troubleshoot or debug this kind of error? Memory dumps and the like seem to be the next step, but I'm not experienced at interpreting them. Perhaps there's something more I can do in the code to try and catch errors... It would be nice if the "Fatal Execution Engine Error" was more informative, but internet searches have only told me that it's a common error for a lot of .NET-related items.

"No message serializer has been configured" error when starting NServiceBus endpoint

- by SteveBering

My GenericHost hosted service is failing to start with the following message: 2010-05-07 09:13:47,406 [1] FATAL NServiceBus.Host.Internal.GenericHost [(null)] <(null) - System.InvalidOperationException: No message serializer has been con figured. at NServiceBus.Unicast.Transport.Msmq.MsmqTransport.CheckConfiguration() in d:\BuildAgent-02\work\672d81652eaca4e1\src\impl\unicast\NServiceBus.Unicast.Msmq\ MsmqTransport.cs:line 241 at NServiceBus.Unicast.Transport.Msmq.MsmqTransport.Start() in d:\BuildAgent-02\work\672d81652eaca4e1\src\impl\unicast\NServiceBus.Unicast.Msmq\MsmqTransport .cs:line 211 at NServiceBus.Unicast.UnicastBus.NServiceBus.IStartableBus.Start(Action startupAction) in d:\BuildAgent-02\work\672d81652eaca4e1\src\unicast\NServiceBus.Uni cast\UnicastBus.cs:line 694 at NServiceBus.Unicast.UnicastBus.NServiceBus.IStartableBus.Start() in d:\BuildAgent-02\work\672d81652eaca4e1\src\unicast\NServiceBus.Unicast\UnicastBus.cs:l ine 665 at NServiceBus.Host.Internal.GenericHost.Start() in d:\BuildAgent-02\work\672d81652eaca4e1\src\host\NServiceBus.Host\Internal\GenericHost.cs:line 77 My endpoint configuration looks like: public class ServiceEndpointConfiguration : IConfigureThisEndpoint, AsA_Publisher, IWantCustomInitialization { public void Init() { // build out persistence infrastructure var sessionFactory = Bootstrapper.InitializePersistence(); // configure NServiceBus infrastructure var container = Bootstrapper.BuildDependencies(sessionFactory); // set up logging log4net.Config.XmlConfigurator.Configure(); Configure.With() .Log4Net() .UnityBuilder(container) .XmlSerializer(); } } And my app.config looks like: <configSections> <section name="MsmqTransportConfig" type="NServiceBus.Config.MsmqTransportConfig, NServiceBus.Core" /> <section name="UnicastBusConfig" type="NServiceBus.Config.UnicastBusConfig, NServiceBus.Core" /> <section name="Logging" type="NServiceBus.Config.Logging, NServiceBus.Core" /> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" requirePermission="false" /> </configSections> <Logging Threshold="DEBUG" /> <MsmqTransportConfig InputQueue="NServiceBus.ServiceInput" ErrorQueue="NServiceBus.Errors" NumberOfWorkerThreads="1" MaxRetries="2" /> <UnicastBusConfig DistributorControlAddress="" DistributorDataAddress="" ForwardReceivedMessagesTo="NServiceBus.Auditing"> <MessageEndpointMappings>  </MessageEndpointMappings> </UnicastBusConfig> <connectionStrings> <add name="Db" connectionString="Data Source=..." providerName="System.Data.SqlClient" /> </connectionStrings> <log4net debug="true"> <root> <level value="INFO"/> </root> <logger name="NHibernate"> <level value="ERROR" /> </logger> </log4net> This has worked in the past, but seems to be failing when the generic host starts. My endpoint configuration is below, along with the app.config for the service. What is strange is that in my endpoint configuration, I am specifying to use the XmlSerializer for message serialization. I don't see any other errors in the console output preceding the error message. What am I missing? Thanks, Steve

WPF - Overlapping Custom Tabs in a TabControl and ZIndex

- by Rachel

Problem I have a custom tab control using Chrome-shaped tabs that binds to a ViewModel. Because of the shape, the edges overlap a bit. I have a function that sets the tabItem's ZIndex on TabControl_SelectionChanged which works fine for selecting tabs, and dragging/dropping tabs, however when I Add or Close a tab via a Relay Command I am getting unusual results. Does anyone have any ideas? Default View http://i193.photobucket.com/albums/z197/Lady53461/tabs_default.jpg Removing Tabs http:/i193.photobucket.com/albums/z197/Lady53461/tabs_removing.jpg Adding 2 or more Tabs in a row http:/i193.photobucket.com/albums/z197/Lady53461/tabs_adding.jpg Code to set ZIndex private void PrimaryTabControl_SelectionChanged(object sender, SelectionChangedEventArgs e) { if (e.Source is TabControl) { TabControl tabControl = sender as TabControl; ItemContainerGenerator icg = tabControl.ItemContainerGenerator; if (icg.Status == System.Windows.Controls.Primitives.GeneratorStatus.ContainersGenerated) { foreach (object o in tabControl.Items) { UIElement tabItem = icg.ContainerFromItem(o) as UIElement; Panel.SetZIndex(tabItem, (o == tabControl.SelectedItem ? 100 : 90 - tabControl.Items.IndexOf(o))); } } } } By using breakpoints I can see that it is correctly setting the ZIndex to what I want it to, however the layout is not displaying the changes. I know some of the changes are in effect because if none of them were working then the tab edges would be reversed (the right tabs would be drawn on top of the left ones). Clicking a tab will correctly set the zindex of all tabs (including the one that should be drawn on top) and dragging/dropping them to rearrange them also renders correctly (which removes and reinserts the tab item). The only difference I can think of is I am using the MVVM design pattern and the buttons that Add/Close tabs are relay commands. Does anyone have any idea why this is happening and how I can fix it?? p.s. I did try setting a ZIndex in my ViewModel and binding to it, however the same thing happens when adding/removing tabs via the relay command. EDIT: Being a new user I couldn't post images and could only post 1 link. Images just show a picture of what the tags render as after each scenario. Adding more then 1 at a time will not reset the zindex of other recently-added tabs so they go behind the tab on the Right, and closing tabs does not correctly render the ZIndex of the SelectedTab that replaces it and it shows up behind the tab on its right.

iPhone Inspiration Stories...

- by Luis Tovar

So we have all heard of these overnight millionaires in the app store. We know it would be great, but somewhat unlikely to do ourselves. What I do know is, that learning and developing for the iPhone can sometimes be overwhelming. I continue to push on and learn more and more, even when my brain just cant take anymore I turn my mac on and read up on how to do new and different things I haven't done yet in my app yet. I would like to see a few post's of a common day developer's story and how their life has improved now that they are sitting up on the golden pedestal of an iphone developer. I look at these Dice.com jobs on think how nice it would be to be making that kind of money offered for an experienced iphone developer. Im on my way... and while I'm on that road i'd like to look over and see your story... Please include how you got into iPhone development and any apps you have out there and your success with them. Care to share?

Working with Subversion the same as with Visual Source Safe in Visual Studio

- by Para

Hi, At work I just started using subversion with ankhsvn instead of visual source safe. I managed to integrate it well enough but it doesn't seem the same. Using VSS the following would happen: A user check out a file by right clicking and selecting "check out" or by editing it. If another user tried to modify the same file he would get an error. No 2 users could edit the same file at the same time. No fancy merging. No conflicts and no conflict resolutions. I understand the the philosophy behind subversion is different but is there any way that this behavior described above could be duplicated with subversion? There is an option in ankhSVN called "Automatically lock files on change..." but even if I activate this option when I edit a file it never gets automatically locked. Even if this option worked the other users wouldn't see the lock until they comited the file. They wouldn't get an error when they tried to edit it like they would in Visual Source Safe. So basically: can Visual Source Safe's behavior be duplicated using Subversion and ankhSVN?
