• Grails + GAE - Issue using app.servlet.version=2.5

  - by Taylor L

  Updating the servlet version in application.properties to 2.5 has no affect on the generated web.xml. The generated web.xml is still version 2.4. app.servlet.version=2.5 Also, if I try to execute "run-app" I get the exception below: Running Grails application.. Starting AppEngine generated indices thread. Starting reload monitor thread.

• [jQuery] Trouble loading tooltips on all images displayed inside Colorbox

  - by adaneko

  I would like to load a tooltip plugin (I'm currently trying qTip, but I've tried a few and have run into the same problem each time) inside Colorbox (http://colorpowered.com/colorbox/). Colorbox dynamically loads this code to display the images you want to show in it: <div id="cboxLoadedContent" style="display: block; width: 400px; overflow: auto; height: 498px;"> <img src="image.jpg" id="cboxPhoto" style="margin: 49px auto auto; border: medium none; display: block; float: none; cursor: pointer;"> </div> Using Colorbox's event hooks, I am currently calling my tooltip plugin on onComplete, but this only applies the tooltip to the first image in the group. If you go to the next image, the tooltip needs to be recalled as Colorbox regenerates the code displayed above. What is the best way to recall the tooltip plugin? I have tried to recall the tooltip by attaching it to clicking on the div with the id "cboxNext" as a test, but it doesn't work since it takes time for cboxPhoto to load, so I think the functions generating the tooltip load before they can apply to the image.

• onPause/onResume activity issues

  - by Josh

  I have a small test application I am working on which has a timer that updates a textview to countdown from 100 to 0. That works fine, but now I am trying to pause the application if the user presses the back button on the phone and then restart the timer from where they left off when they reopen the app. Here is the code I am using: @Override public void onPause() { if(this._timer_time_remaining > 0) { this.timer.cancel(); } super.onPause(); Log.v("Pausing", String.format("Pausing with %d", this._timer_time_remaining)); } @Override public void onResume() { super.onResume(); Log.v("Resuming", String.format("Resuming with %d", this._timer_time_remaining)); if(this._timer_time_remaining > 0) { setContentView(R.layout.in_game); start_timer(this._timer_time_remaining); } } The start_timer() method creates a CountDownTimer which updates the textview in the onTick method and updates the this._timer_time_remaining int variable. CountDownTimer and _timer_time_remaining are both declared at the class level like this: private CountDownTimer timer; private int _timer_time_remaining; From the Log.v() prints I see that the _timer_time_remaining variable has the correct number of seconds stored when onPause is called, but it is set back to 0 when onResume starts. Why does the variable get reset? I thought that the application would continue to run in the background with the same values. Am I missing something? This is all declared in a class that extends Activity. Thanks in advance!

• Mocking WebResponse's from a WebRequest

  - by Rob Cooper

  I have finally started messing around with creating some apps that work with RESTful web interfaces, however, I am concerned that I am hammering their servers every time I hit F5 to run a series of tests.. Basically, I need to get a series of web responses so I can test I am parsing the varying responses correctly, rather than hit their servers every time, I thought I could do this once, save the XML and then work locally. However, I don't see how I can "mock" a WebResponse, since (AFAIK) they can only be instantiated by WebRequest.GetResponse How do you guys go about mocking this sort of thing? Do you? I just really don't like the fact I am hammering their servers :S I dont want to change the code too much, but I expect there is a elegant way of doing this.. Update Following Accept Will's answer was the slap in the face I needed, I knew I was missing a fundamental point! Create an Interface that will return a proxy object which represents the XML. Implement the interface twice, on that uses WebRequest, the other that returns static "responses". The interface implmentation then either instantiates the return type based on the response, or the static XML. You can then pass the required class when testing or at production to the service layer. Once I have the code knocked up, I'll paste some samples. Thanks Will :)

• Is there a way to update a ViewModel in MVC2?

  - by Juvaly

  This code works: [HttpPost] public ActionResult Edit(int id, FormCollection fc) { Movie movie = ( from m in _ctx.Movie.Include("MovieActors") where m.MovieID == id select m ).First(); MovieActorViewModel movieActor = new MovieActorViewModel(movie); if (TryUpdateModel(movieActor)) { _ctx.ApplyPropertyChanges(movieActor.Movie.EntityKey.EntitySetName, movieActor.Movie); _ctx.SaveChanges(); } return View(movieActor); } However, I am not sure how to test this, and in general would much rather have the method take a typed model like: [HttpPost] public ActionResult Edit(MovieActorViewModel movieActor) Is this possible? What changes to my MovieActorViewModel class do I need to make in order to enable this? That class looks like this: public class MovieActorViewModel { public Movie Movie { get; set; } public Actor Actor { get; set; } public PublisherDealViewModel(Movie movie) { this.Movie = movie; this.Actor = ( from a in this.Movie.Actors where a.ActorID == 1 select a ).First(); } } The view is typed (inherits ViewPage) simple: <% using (Html.BeginForm()) {%> Movie Title: <%= Html.TextBoxFor(model=>model.Movie.Title) %><br/> Actor Name: <%= Html.TextBoxFor(model=>model.Actor.Name) %> <% } %>

• Access <body> tag properties from form found in mediaboxAdvanced lightbox.

  - by Christopher Richa

  I am building my portfolio website simply using HTML, Flash, and the Mootools Javascript framework. I have decided to implement a theme changing feature using Javascript and cookies. When the user clicks on the "Change Theme" link, a mediaboxAdvanced lightbox appears, containing a real-time form which allows you to change the theme on the portfolio. Here's the code for the form: <div id="mb_inline" style="display: none; margin:15px;"> <h3>Change Your Theme</h3> <form> <fieldset> <select id="background_color" name="background_color"> <option value="#dcf589">Original</option> <option value="#000FFF">Blue</option> <option value="#00FF00">Green</option> </select> </fieldset> </form> </div> I know, there is no submit button, but as soon as something is changed in that form, the following Mootools code happens: var themeChanger = new Class( { pageBody : null, themeOptions : null, initialize: function() { this.pageBody = $(document.body); this.themeOptions = $('background_color'); this.themeOptions.addEvent('change', this.change_theme.bindWithEvent(this)); }, change_theme: function(event) { alert("Hello"); } }); window.addEvent('domready', function() { var themeChanger_class = new themeChanger(); }); Now this is only a test function, which should be triggered when the dropdown menu changes. However, it seems that none of it works when the form is in the lightbox! Now if I decide to run the form outside of the lightbox, then it works great! Am I missing something? If you need more examples, I will fill in on demand. Thank you all in advance. -Christopher

• About function scopes in javascript

  - by Shawn

  Look at the code below. I want to alert the value of i at the moment that specific listener was added. Is other words, clicking each marker should alert a different value. Where can I store the value of i in a way that it won't change and be accessible inside the scope of that function? Here is problematic code: (it is difficult to test because you need a key from Google) <html> <head> <title>a</title> <script type="text/javascript"> function init() { map = new GMap2(document.getElementById("map_canvas")); // http://code.google.com/intl/es/apis/maps/documentation/reference.html#GMap2 map.setCenter(new GLatLng(0, 0), 1); // http://code.google.com/intl/es/apis/maps/documentation/reference.html#GMap2.setCenter for(var i = 0; i < 10; i++) { var marker = new GMarker(point); // http://code.google.com/intl/es/apis/maps/documentation/reference.html#GMarker map.addOverlay(marker); // http://code.google.com/intl/es/apis/maps/documentation/reference.html#GMap2.addOverlay GEvent.addListener(marker, "click", function() // http://code.google.com/intl/es/apis/maps/documentation/reference.html#GEvent.addListener { alert(i); // Problem: I want the value of i at the moment when the listener is added. }); } } window.onload = init; </script> </head> <body id="map_canvas"> </body> </html> Thanks!

• How to avoid XCode framework weak-linking problems?

  - by Frank R.

  Hi, I'm building an application that takes advantage of Mac OS X 10.6-only technologies, but without giving up backwards compatibility to 10.5 Leopard. The way I do this is by setting the 10.6 SDK as the base SDK, weak-linking all frameworks and setting the deployment target to 10.5 as described in: http://developer.apple.com/mac/library/DOCUMENTATION/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html This works fine; before making a call that is Snow Leopard-only I need to check that the selector or indeed the class actually exist. Or I can just check the OS version before making the call. The problem is that this is incredibly fragile. If I make a single call that is 10.6 only I blow Leopard-compatibility. So using even the normal code code completion feature can be dangerous. My question: is there any way of checking which calls are not defined on 10.5 before doing a release build? Some kind of static analysis, or even just a trick (a target set the other SDK?) would do. I obviously should test on a Leopard machine before releasing anything, but even so I can't possibly go through all paths of the program before every release. Any advice would be appreciated. Best regards, Frank

• iPad receiving memory warning with low memory use

  - by Fer

  I have an UIWebKit with a HTML, this HTML have several images and text, but just displaying it gives me the memory warning. So I did some tests: The same HTML with different images, fullsize, and after the same images but reduced 50% from it's original size, for the 50% reduced images, I went to preview and reduced all images in 50% The surprising part is the 50% test, you can see that even with 16 images, the memory peak is 4.90MB. That's really surprising. Notice that these values are not always the same, they change but there's not a huge difference between the tests. In the 50% issue, in the 8 and 16 images, although the memory is low, sometimes a memory warning appears, but the performance enhance is noticeable compared to the full size images standing still = memory after scrolling all article 1 Image = [standing still 5MB] [rotating 5.6MB] 2 Images = [standing still 6.99MB] [rotating 7.7MB] 3 Images = [standing still 9.04MB] [rotating 10.9MB] 4 Images = [standing still 10.89MB] [rotating 13.20MB] 8 Images = [standing still 23.14MB] [rotating 25.20MB] (sometimes crashes) 16 Images = [standing still 27.14MB and app crashes] 50% 1 Image = [standing still 3.2MB] [rotating 3.67MB] 2 Image = [standing still 3.2MB] [rotating 3.70MB] 3 Image = [standing still 3.3MB] [rotating 3.79MB] 4 Image = [standing still 3.3MB] [rotating 3.80MB] 8 Images = [standing still 4.29MB] [rotating 4,63MB] (sometimes crashes) 16 Images = [standing still 4.79MB] [rotating 4,90MB] (sometimes crashes) My question is: The app sometimes crashed with 16 small images. Why? The memory was much lower. What is the limit of memory use? These numbers are helpful if you also tell us the maximum. But, the maximum seemed different with the 50% size images. 13.2MB works for large images and 3.8 for small images. Anything higher sometimes crashes. That makes no sense.

• UpdatePanel not working in IE or Chrome

  - by gevjen

  I have an updatepanel on my masterpage. Within the contentplace holder I have my update progress control. When a user clicks on the button I load some data into a gridview. This works perfectly in FireFox. User clicks the button, the loading image in my updateprogress fires and loads the gridview. When I test this in IE 6 or 7 or in Chrome. It does a full postback and the updateprogress is never shown. So the updatepanel doesnt seem to be working in these two browsers. Code is below. Again...it works perfect in FireFox. ***From Masterpage *** <asp:UpdatePanel ID="UpdatePanel" runat="server"> <contenttemplate> <asp:contentplaceholder id="holder" runat="server" /> </contenttemplate> </asp:UpdatePanel> **From aspx page **** <asp:UpdateProgress ID="UpdateProgress1" runat="server"> <ProgressTemplate> <img src="ajax-loader.gif" /> </ProgressTemplate> </asp:UpdateProgress>

• Using Entity Framework with an SQL Compact Private Installation

  - by David Veeneman

  I am using Entity Framework 4 in a desktop application with SQL Compact. I want to use a private installation of SQL Compact with my application, so that my installer can install SQL Compact without giving the user a second installation to do. It also avoids versioning hassles down the road. My development machine has SQL Compact 3.5 SP1 installed as a public installation, so my app runs fine there, as one would expect. But it's not running on my test machine, which does not have SQL Compact installed. I get this error: The specified store provider cannot be found in the configuration, or is not valid. I know some people have had difficulty with SQL Compact private installations, but I have used them for a while, and I really like them. Unfortunately, my regular private installation approach isn't working. I have checked the version numbers on my SQL CE files, and they are all 3.8.8078.0, which is the SP2 RC version. Here are the files I have included in my private installation: sqlcecompact35.dll sqlceer35EN.dll sqlceme35.dll sqlceqp35.dll sqlcese35.dll System.Data.SqlServerCe.dll System.Data.SqlServerCe.Entity.dll I have added a reference to System.Data.SqlServerCe to my project, and I have verified that all of the files listed above are being copied to the application folder on the installation machine. Here is the code I use to configure an EntityConnectionStringBuilder when I open a SQL Compact file: var sqlCompactConnectionString = string.Format("Data Source={0}", filePath); // Set Builder properties builder.Metadata = string.Format("res://*/{0}.csdl|res://*/{0}.ssdl|res://*/{0}.msl", edmName); builder.Provider = "System.Data.SqlServerCe.3.5"; builder.ProviderConnectionString = sqlCompactConnectionString; var edmConnectionString = builder.ToString(); Am I missing a file? Am I missing a configuration stepp needed to tell Entity Framework where to find my SQL Compact DLLs? Any other suggestions why EF isn't finding my SQL Compact DLLs on the installation machine? Thanks for your help.

• Custom IIdentity and passing data from an attribute to a controller

  - by DM

  Here's my scenario: I've successfully created a custom IIdentity that I pass to a GenericPrincipal. When I access that IIdentity in my controller I have to cast the IIdentity in order to use the custom properties. example: public ActionResult Test() { MyCustomIdentity identity = (MyCustomIdentity)User.Identity; int userID = identity.UserID; ...etc... } Since I need to do this casting for nearly every action I would like to wrap this functionality in an ActionFilterAttribute. I can't do it in the controller's constructor because the context isn't initialized yet. My thought would be to have the ActionFilterAttribute populate a private property on the controller that I can use in each action method. example: public class TestController : Controller { private MyCustomIdentity identity; [CastCustomIdentity] public ActionResult() { int userID = identity.UserID; ...etc... } } Question: Is this possible and how? Is there a better solution? I've racked my brain trying to figure out how to pass public properties that are populated in an attribute to the controller and I can't get it.

• That assembly does not allow partially trusted callers although the zone is fully trusted.

  - by Frederik Gheysels

  Since yesterday, I receive a security exception when I want to run a unit-test from within VS.NET 2008. The error goes like this: SecurityException: that assembly does not allow partially trusted callers ... The assembly that failed was : file:///S:/MyProject/MyAssembly.dll The S: drive is a mapped drive which points to a physical location on my disk. What I find very strange, is that this used to work for months previously. I mean, I did this all the time. In order to get this to work, I 've created a new security zone with the caspol utility in order to give this S: network share drive FullTrust. In other words, when I run caspol -m -lg I see this (I removed the other zones for the sake of brevity): 1.2. Zone - Intranet: LocalIntranet 1.2.1. All code: Same site Web 1.2.2. All code: Same directory FileIO - 'Read, PathDiscovery' 1.2.3. Url - file://R:/*: FullTrust 1.2.4. Url - file://S:/*: FullTrust 1.2.5. Url - file:///S:/*: FullTrust I've added the 1.2.5 zone just recently because the error that was given, mentionned file:///s:/.... Any ideas ? Could it be that this has something to do with the installation of VS.NET 2010 or the .NET Framework version 4.0 ?

• Playing online video on iphone web, the iphone seems to cache the reference movie

  - by Mad Oxyn

  We are working on an online mobile video app, and are trying to play a reference movie on an iphone from the iphone browser. The problem is, the movie plays the first time, but when we try to play a different movie the second time, it doesnt. Quicktime gives a general error message sayin "Cannot Play Movie". More precisely this is what we are trying to do: Connect with an iPhone to a webserver that serves a reference movie (generated with quicktime pro). The ref movie automatically gets downloaded to the iphone by quicktime. Quicktime then chooses one of the 3 references in the reference movie, based on the connection speed, and tries to download the designated movie via a relative path. A servlet gets called and forwards the relative path to the right movie. This all works the first time. However the second time when we want download different movies, we get the quicktime error. Test case: Open reference movie 1 Movie plays in Quicktime Open reference movie 2 ERROR: Quicktime gives an error - Cannot Play Movie Shut down Iphone Turn Iphone on again Open reference movie 2 Iphone plays movie Open movie ERROR: Quicktime gives an error - Cannot Play Movie Did anyone encounter similar issues with quicktime and the use of reference movies and is there something we can do to work around that?

• SVN Workflow - Chicken Before the Egg - Before merging V1 with V2, I need code from V1 to work on V2

  - by Jake

  Hi, Our distributed team (3 internal devs and 3+ external devs) use SVN to manage our codebase for a web site. We have a branch for each minor version (4.1.0, 4.1.1, 4.1.2, etc...). We have a trunk which we merge each version into when we do a release and publish to our site. An example of the problem we are having is thus: A new feature is added, lets call it "Ability to Create A Project" to 4.1.1. Another feature which depends on the one in 4.1.1 is scheduled to go in 4.1.2, called "Ability to Add Tasks to Projects". So, on Monday, we say 4.1.1 is 'closed' and needs to be tested. Our remote developers usually will start working on features/tickets for 4.1.2 at this point. Throughout the week we will test 4.1.1 and fix any bugs and commit them back to 4.1.1. Then, on Friday or so, we will tag 4.1.1, merge it with trunk, and finally, merge it with 4.1.2. But, for the 4-5 days we are testing, 4.1.2 doesn't have the code from 4.1.1 that some of the new features for 4.1.2 depend on. So a dev who is adding the "Ability to Add Tasks To Projects" feature, doesn't have the "Ability to Create a Project" feature to build upon, and has to do some file copy shenanigans to be able to keep working on it. What could/should we do to smooth out this process? P.S. Apologies if this question has been asked before - I did search but couldn't find what I'm looking for.

• Command-Line Parsing API from TestAPI library - Type-Safe Commands how to

  - by MicMit

  Library at http://testapi.codeplex.com/ Excerpt of usage from http://blogs.msdn.com/ivo_manolov/archive/2008/12/17/9230331.aspx A third common approach is forming strongly-typed commands from the command-line parameters. This is common for cases when the command-line looks as follows: some-exe COMMAND parameters-to-the-command The parsing in this case is a little bit more involved: Create one class for every supported command, which derives from the Command abstract base class and implements an expected Execute method. Pass an expected command along with the command-line arguments to CommandLineParser.ParseCommand – the method will return a strongly-typed Command instance that can be Execute()-d. // EXAMPLE #3: // Sample for parsing the following command-line: // Test.exe run /runId=10 /verbose // In this particular case we have an actual command on the command-line (“run”), which we want to effectively de-serialize and execute. public class RunCommand : Command { bool? Verbose { get; set; } int? RunId { get; set; } public override void Execute() { // Implement your "run" execution logic here. } } Command c = new RunCommand(); CommandLineParser.ParseArguments(c, args); c.Execute(); ============================ I don't get if we instantiate specific class before parsing arguments , what's the point of command line argument "run" which is very first one. I thought the idea was to instantiate and execute command/class based on a command line parameter ( "run" parameter becomes instance RunCommand class, "walk" becomes WalkCommand class and so on ). Can it be done with the latest version ?

• How do I configure a C# web service client to send HTTP request header and body in parallel?

  - by Christopher

  Hi, I am using a traditional C# web service client generated in VS2008 .Net 3.5, inheriting from SoapHttpClientProtocol. This is connecting to a remote web service written in Java. All configuration is done in code during client initialization, and can be seen below: ServicePointManager.Expect100Continue = false; ServicePointManager.DefaultConnectionLimit = 10; var client = new APIService { EnableDecompression = true, Url = _url + "?guid=" + Guid.NewGuid(), Credentials = new NetworkCredential(user, password, null), PreAuthenticate = true, Timeout = 5000 // 5 sec }; It all works fine, but the time taken to execute the simplest method call is almost double the network ping time. Whereas a Java test client takes roughly the same as the network ping time: C# client ~ 550ms Java client ~ 340ms Network ping ~ 300ms After analyzing the TCP traffic for a session discovered the following: Basically, the C# client sent TCP packets in the following sequence. Client Send HTTP Headers in one packet. Client Waits For TCP ACK from server. Client Sends HTTP Body in one packet. Client Waits For TCP ACK from server. The Java client sent TCP packets in the following sequence. Client Sends HTTP Headers in one packet. Client Sends HTTP Body in one packet. Client Revieves ACK for first packet. Client Revieves ACK for second packet. Client Revieves ACK for second packet. Is there anyway to configure the C# web service client to send the header/body in parallel as the Java client appears to? Any help or pointers much appreciated.

• xcopy failing within TFSbuild

  - by mattgcon

  I am using TFS2008 and within my TFSBuild.proj file I have a target that call xcopy to copy the build to the production website location for automation. However I am receiving the following error when running the build: Task "Exec" Command: xcopy "\\test\TFSBuilds\Online System V2 Build to NETPUB_20100430.2\Debug\_PublishedWebsites\IPAMIntranet" " C:\\Inetpub\wwwroot\IPAMOnlineSystem\IPAMIntranet\IPAMIntranet " /E Parse Error 'C:\\Inetpub\wwwroot\IPAMOnlineSystem\IPAMIntranet\IPAMIntranet' is not recognized as an internal or external command, operable program or batch file. '" /E ' is not recognized as an internal or external command, operable program or batch file. The following is my code line for the xcopy: <Target Name="AfterDropBuild"> <Exec Command="xcopy &quot;$(DropLocation)\$(BuildNumber)\Debug\_PublishedWebsites\IPAMIntranet&quot; &quot;$(RemoteDeploySitePath)&quot; /E " /> </Target> I have even tried single quotes around the file locations and actual double quotes insteand of the " symbols. Why is this happening, can anyone decipher this for me and help me correct this.

• RSA Decrypting a string in C# which was encrypted with openssl in php 5.3.2

  - by panny

  maybe someone can clear me up. I have been surfing on this a while now. I used openssl from console to create a root certificate for me (privatekey.pem, publickey.pem, mycert.pem, mycertprivatekey.pfx). See the end of this text on how. The problem is still to get a string encrypted on the PHP side to be decrypted on the C# side with RSACryptoServiceProvider. Any ideas? PHP side I used the publickey.pem to read it into php: $server_public_key = openssl_pkey_get_public(file_get_contents("C:\publickey.pem")); // rsa encrypt openssl_public_encrypt("123", $encrypted, $server_public_key); and the privatekey.pem to check if it works: openssl_private_decrypt($encrypted, $decrypted, openssl_get_privatekey(file_get_contents("C:\privatekey.pem"))); Coming to the conclusion, that encryption/decryption works fine on the php side with these openssl root certificate files. C# side In same manner I read the keys into a .net C# console program: X509Certificate2 myCert2 = new X509Certificate2(); RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); try { myCert2 = new X509Certificate2(@"C:\mycertprivatekey.pfx"); rsa = (RSACryptoServiceProvider)myCert2.PrivateKey; } catch (Exception e) { } string t = Convert.ToString(rsa.Decrypt(rsa.Encrypt(test, false), false)); coming to the point, that encryption/decryption works fine on the c# side with these openssl root certificate files. key generation on unix 1) openssl req -x509 -nodes -days 3650 -newkey rsa:1024 -keyout privatekey.pem -out mycert.pem 2) openssl rsa -in privatekey.pem -pubout -out publickey.pem 3) openssl pkcs12 -export -out mycertprivatekey.pfx -in mycert.pem -inkey privatekey.pem -name "my certificate"
