• Android app crashes on emulator - logCat shows no errors

  - by David Miler

  I have just added the SherlockActionBar library to my android project. After some small changes (FragmentActivity - SherlockFragmentActivity, getActionBar() - getSupportActionBar(), imports) it all compiled nicely. After I run the app, however, the debugger stops, as though it had encountered an exception. However, there are no errors shown in the LogCat output. I just can't wrap my head around what's going on. Here is the logCat output after I terminate the app. 10-02 14:11:19.227: I/SystemUpdateService(174): UpdateTask at time 1349187079227 10-02 14:11:19.237: I/ActivityThread(328): Pub com.android.email.attachmentprovider: com.android.email.provider.AttachmentProvider 10-02 14:11:19.687: I/dalvikvm(81): Jit: resizing JitTable from 512 to 1024 10-02 14:11:19.809: D/MediaScannerService(150): start scanning volume internal: [/system/media] 10-02 14:11:20.047: V/AlarmClock(239): AlarmInitReceiver finished 10-02 14:11:20.087: I/ActivityManager(81): Start proc com.android.quicksearchbox for broadcast com.android.quicksearchbox/.SearchWidgetProvider: pid=346 uid=10012 gids={3003} 10-02 14:11:20.127: D/ExchangeService(320): !!!

• How to tune down the Hyperic built-in postgresql database for a small setup

  - by Svish

  We are testing out Hyperic 4.5.1 in a quite small environment for now. Currently there are just 1-5 agents and there probably won't be any more than 10-15. When I run ps ax there are 20(!) postgres processes running. For a small setup like this, that can't be necessary, can it? I'm a software developer and don't have much experience with setting up servers and such though, so don't really know. Either way, what settings are appropriate for a small Hyperic setup like this? Current, default and untouched configuration file, hqdb/data/postgresql.conf: # ----------------------------- # PostgreSQL configuration file # ----------------------------- # # This file consists of lines of the form: # # name = value # # (The '=' is optional.) White space may be used. Comments are introduced # with '#' anywhere on a line. The complete list of option names and # allowed values can be found in the PostgreSQL documentation. The # commented-out settings shown in this file represent the default values. # # Please note that re-commenting a setting is NOT sufficient to revert it # to the default value, unless you restart the server. # # Any option can also be given as a command line switch to the server, # e.g., 'postgres -c log_connections=on'. Some options can be changed at # run-time with the 'SET' SQL command. # # This file is read on server startup and when the server receives a # SIGHUP. If you edit the file on a running system, you have to SIGHUP the # server for the changes to take effect, or use "pg_ctl reload". Some # settings, which are marked below, require a server shutdown and restart # to take effect. # # Memory units: kB = kilobytes MB = megabytes GB = gigabytes # Time units: ms = milliseconds s = seconds min = minutes h = hours d = days #--------------------------------------------------------------------------- # FILE LOCATIONS #--------------------------------------------------------------------------- # The default values of these variables are driven from the -D command line # switch or PGDATA environment variable, represented here as ConfigDir. #data_directory = 'ConfigDir' # use data in another directory # (change requires restart) #hba_file = 'ConfigDir/pg_hba.conf' # host-based authentication file # (change requires restart) #ident_file = 'ConfigDir/pg_ident.conf' # ident configuration file # (change requires restart) # If external_pid_file is not explicitly set, no extra PID file is written. #external_pid_file = '(none)' # write an extra PID file # (change requires restart) #--------------------------------------------------------------------------- # CONNECTIONS AND AUTHENTICATION #--------------------------------------------------------------------------- # - Connection Settings - #listen_addresses = 'localhost' # what IP address(es) to listen on; # comma-separated list of addresses; # defaults to 'localhost', '*' = all # (change requires restart) port = 9432 # (change requires restart) max_connections = 100 # (change requires restart) # Note: increasing max_connections costs ~400 bytes of shared memory per # connection slot, plus lock space (see max_locks_per_transaction).

• TCP packets larger than 4 KB don't get a reply from Linux

  - by pts

  I'm running Linux 3.2.51 in a virtual machine (192.168.33.15). I'm sending Ethernet frames to it. I'm writing custom software trying to emulate a TCP peer, the other peer is Linux running in the virtual machine guest. I've noticed that TCP packets larger than about 4 KB are ignored (i.e. dropped without an ACK) by the Linux guest. If I decrease the packet size by 50 bytes, I get an ACK. I'm not sending new payload data until the Linux guest fully ACKs the previous one. I've increased ifconfig eth0 mtu 51000, and ping -c 1 -s 50000 goes through (from guest to my emulator) and the Linux guest gets a reply of the same size. I've also increased sysctl -w net.ipv4.tcp_rmem='70000 87380 87380 and tried with sysctl -w net.ipv4.tcp_mtu_probing=1 (and also =0). There is no IPv3 packet fragmentation, all packets have the DF flag set. It works the other way round: the Linux guest can send TCP packets of 6900 bytes of payload and my emulator understands them. This is very strange to me, because only TCP packets seem to be affected (large ICMP packets go through). Any idea what can be imposing this limit? Any idea how to do debug it in the Linux kernel? See the tcpdump -n -vv output below. tcpdump was run on the Linux guest. The last line is interesting: 4060 bytes of TCP payload is sent to the guest, and it doesn't get any reply packet from the Linux guest for half a minute. 14:59:32.000057 IP (tos 0x0, ttl 64, id 0,

Are there permissions on the directories that ls -l wouldn't show? I'm the owner of all directories and files inside them. I can sudo to modify the file permissions or view the contents of the folders but I need them to be accessible by 'admin'. Any ideas? I'll be checking the question regularly so let me know if I need to update this with more information.

The Inbox sits at the following location /home/admin/MyLibrary/MyVideos/Inbox /home/admin/MyLibrary/MyVideos/Movies The system is a Netgear Stora NAS box that I have root access to. The /home/ folder is mounted as an smb share on various computers around the house. The folder /Inbox cannot be opened on any of those machines (they all connect as 'admin'). When I ssh into the box using the 'admin' credentials I am also unable to access the folder. The folder was created via a Web Admin page hosted on the NAS. The user/group for the Inbox folder was previously apache:www (expected as this folder was created by the web application), but I chmod/chowned the folder as the root user in an attempt to grant the admin user (therefore the rest of the connected machines) access to the files. Sorry for not including this earlier, I wasn't sure if it was relevant and didn't want to confuse the situation. -Thanks 3rd Edit Sorry again - It looks like this NAS is running some custom version of Red Hat, not Debian as previously stated - I'm not sure if this makes a difference

• GRUB doesn't recognize partitions on one harddisk

  - by knizz

  I have a dualboot computer with Windows Vista (on hd0) and Ubuntu 9.10. The bootloader is GRUB and the windows bootloader lets me decide between Vista and Ubuntu-Installation (broken WuBi). But now (i don't know why that changed) I can't use start the windows-bootloader anymore. I tried "ls" on the grub-prompt and it gave me a list like: (hd0) (hd1) (hd1,0) (hd1,1) (hd1,2) ... (fd0) It recognizes all partitions of hd1 (the ubuntu-harddisk) but not of hd0(the win-disk). .. WHY? Here is the result of the "boot info script" for the technical details: Boot Info Script 0.55 dated February 15th, 2010 ============================= Boot Info Summary: ============================== => Grub 2 is installed in the MBR of /dev/sda and looks for (UUID=a7c510e3-2399-437b-ab92-fa609e48d63f)/boot/grub. => No boot loader is installed in the MBR of /dev/sdb sda1: _________________________________________________________________________ File system: ntfs Boot sector type: Windows Vista/7 Boot sector info: No errors found in the Boot Parameter Block.

All code: FullTrust Success Our application is running on three servers, two of them are on Server 2008 Web x64 while the third is running Server 2008 R2 Web x64, all have .NET 3.5 installed, no .NET 4.0 installations. The problem only occurs on the first two that are running 2008 non R2. Running depends.exe on all three servers gives equal results for the nonR2 servers: My DLL is shown as x86 (compiled as AnyCPU, running in x64 w3wp), all other modules show as x64. Missing IESHIMS.DLL and LINKINFO.DLL - both of these seem to be red herrings according to Google. The third server shows the same, except it does not miss LINKINFO.DLL All servers are running IIS7 (7.5 for the R2 one) under a custom domain account that has been granted the necessary permissions: aspnet_regiis -ga [user] Load user profile is set to false on all three servers. I've tried setting this to true on one of the faulting servers, according to: http://stackoverflow.com/questions/1846816/iis7-failed-to-grant-minimum-permission-requests By running processmonitor I can see that it's now using the C:\Users\TEMP\AppData\Local\Temp directory for various temp files - the other ones are not using any such directory. So far I'll let it run in this way to see if this changes anything. I'm in doubt however given that the third server is not exhibiting the problems, yet still has "Load user profile" set to the same value, false. I've also tried running Fuslogvw on all three servers, logging binding failures to disk. All three servers report the same binding errors for VJSharpCodeProvider and CppCodeProvider, but these seem to be normal as well and can be solved by not defining the DEBUG and TRACE constants during build. We're running about 500 websites on each server (identical, load balanced), of which 50 are under moderate load, the problem has arisen both under heavy load as well as under minimal load however. Right now I'm waiting for the errors to happen again so I can hopefully see a pattern and determine whether "Load user profile" alleviates the issue. Any suggestions in the meantime would be very welcome! Also, I don't understand how the lack of "Load user profile" would cause an issue like this? And even further, how it would seemingly work on R2 but not on plain 2008? Thanks!

• A plugin is preventing Eclipse from starting up

  It just gives me a blank window, and the splash screen doesn't go away. I tried running it in a terminal, turns out it's a problematic plugin. Is there a way to disable that plugin without the GUI?

• AngularJS on top of ASP.NET: Moving the MVC framework out to the browser

  - by Varun Chatterji

  Heavily drawing inspiration from Ruby on Rails, MVC4’s convention over configuration model of development soon became the Holy Grail of .NET web development. The MVC model brought with it the goodness of proper separation of concerns between business logic, data, and the presentation logic. However, the MVC paradigm, was still one in which server side .NET code could be mixed with presentation code. The Razor templating engine, though cleaner than its predecessors, still encouraged and allowed you to mix .NET server side code with presentation logic. Thus, for example, if the developer required a certain <div> tag to be shown if a particular variable ShowDiv was true in the View’s model, the code could look like the following: Fig 1: To show a div or not. Server side .NET code is used in the View Mixing .NET code with HTML in views can soon get very messy. Wouldn’t it be nice if the presentation layer (HTML) could be pure HTML? Also, in the ASP.NET MVC model, some of the business logic invariably resides in the controller. It is tempting to use an anti­pattern like the one shown above to control whether a div should be shown or not. However, best practice would indicate that the Controller should not be aware of the div. The ShowDiv variable in the model should not exist. A controller should ideally, only be used to do the plumbing of getting the data populated in the model and nothing else. The view (ideally pure HTML) should render the presentation layer based on the model. In this article we will see how Angular JS, a new JavaScript framework by Google can be used effectively to build web applications where: 1. Views are pure HTML 2. Controllers (in the server sense) are pure REST based API calls 3. The presentation layer is loaded as needed from partial HTML only files. What is MVVM? MVVM short for Model View View Model is a new paradigm in web development. In this paradigm, the Model and View stuff exists on the client side through javascript instead of being processed on the server through postbacks. These frameworks are JavaScript frameworks that facilitate the clear separation of the “frontend” or the data rendering logic from the “backend” which is typically just a REST based API that loads and processes data through a resource model. The frameworks are called MVVM as a change to the Model (through javascript) gets reflected in the view immediately i.e. Model > View. Also, a change on the view (through manual input) gets reflected in the model immediately i.e. View > Model. The following figure shows this conceptually (comments are shown in red): Fig 2: Demonstration of MVVM in action In Fig 2, two text boxes are bound to the same variable model.myInt. Thus, changing the view manually (changing one text box through keyboard input) also changes the other textbox in real time demonstrating V > M property of a MVVM framework. Furthermore, clicking the button adds 1 to the value of model.myInt thus changing the model through JavaScript. This immediately updates the view (the value in the two textboxes) thus demonstrating the M > V property of a MVVM framework. Thus we see that the model in a MVVM JavaScript framework can be regarded as “the single source of truth“. This is an important concept. Angular is one such MVVM framework. We shall use it to build a simple app that sends SMS messages to a particular number. Application, Routes, Views, Controllers, Scope and Models Angular can be used in many ways to construct web applications. For this article, we shall only focus on building Single Page Applications (SPAs). Many of the approaches we will follow in this article have alternatives. It is beyond the scope of this article to explain every nuance in detail but we shall try to touch upon the basic concepts and end up with a working application that can be used to send SMS messages using Sent.ly Plus (a service that is itself built using Angular). Before you read on, we would like to urge you to forget what you know about Models, Views, Controllers and Routes in the ASP.NET MVC4 framework. All these words have different meanings in the Angular world. Whenever these words are used in this article, they will refer to Angular concepts and not ASP.NET MVC4 concepts. The following figure shows the skeleton of the root page of an SPA: Fig 3: The skeleton of a SPA The skeleton of the application is based on the Bootstrap starter template which can be found at: http://getbootstrap.com/examples/starter­template/ Apart from loading the Angular, jQuery and Bootstrap JavaScript libraries, it also loads our custom scripts /app/js/controllers.js /app/js/app.js These scripts define the routes, views and controllers which we shall come to in a moment. Application Notice that the body tag (Fig. 3) has an extra attribute: ng­app=”smsApp” Providing this tag “bootstraps” our single page application. It tells Angular to load a “module” called smsApp. This “module” is defined /app/js/app.js angular.module('smsApp', ['smsApp.controllers', function () {}]) Fig 4: The definition of our application module The line shows above, declares a module called smsApp. It also declares that this module “depends” on another module called “smsApp.controllers”. The smsApp.controllers module will contain all the controllers for our SPA. Routing and Views Notice that in the Navbar (in Fig 3) we have included two hyperlinks to: “#/app” “#/help” This is how Angular handles routing. Since the URLs start with “#”, they are actually just bookmarks (and not server side resources). However, our route definition (in /app/js/app.js) gives these URLs a special meaning within the Angular framework. angular.module('smsApp', ['smsApp.controllers', function () { }]) //Configure the routes .config(['$routeProvider', function ($routeProvider) { $routeProvider.when('/binding', { templateUrl: '/app/partials/bindingexample.html', controller: 'BindingController' }); }]); Fig 5: The definition of a route with an associated partial view and controller As we can see from the previous code sample, we are using the $routeProvider object in the configuration of our smsApp module. Notice how the code “asks for” the $routeProvider object by specifying it as a dependency in the [] braces and then defining a function that accepts it as a parameter. This is known as dependency injection. Please refer to the following link if you want to delve into this topic: http://docs.angularjs.org/guide/di What the above code snippet is doing is that it is telling Angular that when the URL is “#/binding”, then it should load the HTML snippet (“partial view”) found at /app/partials/bindingexample.html. Also, for this URL, Angular should load the controller called “BindingController”. We have also marked the div with the class “container” (in Fig 3) with the ng­view attribute. This attribute tells Angular that views (partial HTML pages) defined in the routes will be loaded within this div. You can see that the Angular JavaScript framework, unlike many other frameworks, works purely by extending HTML tags and attributes. It also allows you to extend HTML with your own tags and attributes (through directives) if you so desire, you can find out more about directives at the following URL: http://www.codeproject.com/Articles/607873/Extending­HTML­with­AngularJS­Directives Controllers and Models We have seen how we define what views and controllers should be loaded for a particular route. Let us now consider how controllers are defined. Our controllers are defined in the file /app/js/controllers.js. The following snippet shows the definition of the “BindingController” which is loaded when we hit the URL http://localhost:port/index.html#/binding (as we have defined in the route earlier as shown in Fig 5). Remember that we had defined that our application module “smsApp” depends on the “smsApp.controllers” module (see Fig 4). The code snippet below shows how the “BindingController” defined in the route shown in Fig 5 is defined in the module smsApp.controllers: angular.module('smsApp.controllers', [function () { }]) .controller('BindingController', ['$scope', function ($scope) { $scope.model = {}; $scope.model.myInt = 6; $scope.addOne = function () { $scope.model.myInt++; } }]); Fig 6: The definition of a controller in the “smsApp.controllers” module. The pieces are falling in place! Remember Fig.2? That was the code of a partial view that was loaded within the container div of the skeleton SPA shown in Fig 3. The route definition shown in Fig 5 also defined that the controller called “BindingController” (shown in Fig 6.) was loaded when we loaded the URL: http://localhost:22544/index.html#/binding The button in Fig 2 was marked with the attribute ng­click=”addOne()” which added 1 to the value of model.myInt. In Fig 6, we can see that this function is actually defined in the “BindingController”. Scope We can see from Fig 6, that in the definition of “BindingController”, we defined a dependency on $scope and then, as usual, defined a function which “asks for” $scope as per the dependency injection pattern. So what is $scope? Any guesses? As you might have guessed a scope is a particular “address space” where variables and functions may be defined. This has a similar meaning to scope in a programming language like C#. Model: The Scope is not the Model It is tempting to assign variables in the scope directly. For example, we could have defined myInt as $scope.myInt = 6 in Fig 6 instead of $scope.model.myInt = 6. The reason why this is a bad idea is that scope in hierarchical in Angular. Thus if we were to define a controller which was defined within the another controller (nested controllers), then the inner controller would inherit the scope of the parent controller. This inheritance would follow JavaScript prototypal inheritance. Let’s say the parent controller defined a variable through $scope.myInt = 6. The child controller would inherit the scope through java prototypical inheritance. This basically means that the child scope has a variable myInt that points to the parent scopes myInt variable. Now if we assigned the value of myInt in the parent, the child scope would be updated with the same value as the child scope’s myInt variable points to the parent scope’s myInt variable. However, if we were to assign the value of the myInt variable in the child scope, then the link of that variable to the parent scope would be broken as the variable myInt in the child scope now points to the value 6 and not to the parent scope’s myInt variable. But, if we defined a variable model in the parent scope, then the child scope will also have a variable model that points to the model variable in the parent scope. Updating the value of $scope.model.myInt in the parent scope would change the model variable in the child scope too as the variable is pointed to the model variable in the parent scope. Now changing the value of $scope.model.myInt in the child scope would ALSO change the value in the parent scope. This is because the model reference in the child scope is pointed to the scope variable in the parent. We did no new assignment to the model variable in the child scope. We only changed an attribute of the model variable. Since the model variable (in the child scope) points to the model variable in the parent scope, we have successfully changed the value of myInt in the parent scope. Thus the value of $scope.model.myInt in the parent scope becomes the “single source of truth“. This is a tricky concept, thus it is considered good practice to NOT use scope inheritance. More info on prototypal inheritance in Angular can be found in the “JavaScript Prototypal Inheritance” section at the following URL: https://github.com/angular/angular.js/wiki/Understanding­Scopes. Building It: An Angular JS application using a .NET Web API Backend Now that we have a perspective on the basic components of an MVVM application built using Angular, let’s build something useful. We will build an application that can be used to send out SMS messages to a given phone number. The following diagram describes the architecture of the application we are going to build: Fig 7: Broad application architecture We are going to add an HTML Partial to our project. This partial will contain the form fields that will accept the phone number and message that needs to be sent as an SMS. It will also display all the messages that have previously been sent. All the executable code that is run on the occurrence of events (button clicks etc.) in the view resides in the controller. The controller interacts with the ASP.NET WebAPI to get a history of SMS messages, add a message etc. through a REST based API. For the purposes of simplicity, we will use an in memory data structure for the purposes of creating this application. Thus, the tasks ahead of us are: Creating the REST WebApi with GET, PUT, POST, DELETE methods. Creating the SmsView.html partial Creating the SmsController controller with methods that are called from the SmsView.html partial Add a new route that loads the controller and the partial. 1. Creating the REST WebAPI This is a simple task that should be quite straightforward to any .NET developer. The following listing shows our ApiController: public class SmsMessage { public string to { get; set; } public string message { get; set; } } public class SmsResource : SmsMessage { public int smsId { get; set; } } public class SmsResourceController : ApiController { public static Dictionary<int, SmsResource> messages = new Dictionary<int, SmsResource>(); public static int currentId = 0; // GET api/<controller> public List<SmsResource> Get() { List<SmsResource> result = new List<SmsResource>(); foreach (int key in messages.Keys) { result.Add(messages[key]); } return result; } // GET api/<controller>/5 public SmsResource Get(int id) { if (messages.ContainsKey(id)) return messages[id]; return null; } // POST api/<controller> public List<SmsResource> Post([FromBody] SmsMessage value) { //Synchronize on messages so we don't have id collisions lock (messages) { SmsResource res = (SmsResource) value; res.smsId = currentId++; messages.Add(res.smsId, res); //SentlyPlusSmsSender.SendMessage(value.to, value.message); return Get(); } } // PUT api/<controller>/5 public List<SmsResource> Put(int id, [FromBody] SmsMessage value) { //Synchronize on messages so we don't have id collisions lock (messages) { if (messages.ContainsKey(id)) { //Update the message messages[id].message = value.message; messages[id].to = value.message; } return Get(); } } // DELETE api/<controller>/5 public List<SmsResource> Delete(int id) { if (messages.ContainsKey(id)) { messages.Remove(id); } return Get(); } } Once this class is defined, we should be able to access the WebAPI by a simple GET request using the browser: http://localhost:port/api/SmsResource Notice the commented line: //SentlyPlusSmsSender.SendMessage The SentlyPlusSmsSender class is defined in the attached solution. We have shown this line as commented as we want to explain the core Angular concepts. If you load the attached solution, this line is uncommented in the source and an actual SMS will be sent! By default, the API returns XML. For consumption of the API in Angular, we would like it to return JSON. To change the default to JSON, we make the following change to WebApiConfig.cs file located in the App_Start folder. public static class WebApiConfig { public static void Register(HttpConfiguration config) { config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); var appXmlType = config.Formatters.XmlFormatter. SupportedMediaTypes. FirstOrDefault( t => t.MediaType == "application/xml"); config.Formatters.XmlFormatter.SupportedMediaTypes.Remove(appXmlType); } } We now have our backend REST Api which we can consume from Angular! 2. Creating the SmsView.html partial This simple partial will define two fields: the destination phone number (international format starting with a +) and the message. These fields will be bound to model.phoneNumber and model.message. We will also add a button that we shall hook up to sendMessage() in the controller. A list of all previously sent messages (bound to model.allMessages) will also be displayed below the form input. The following code shows the code for the partial: <!--­­ If model.errorMessage is defined, then render the error div -­­> <div class="alert alert-­danger alert-­dismissable" style="margin­-top: 30px;" ng­-show="model.errorMessage != undefined"> <button type="button" class="close" data­dismiss="alert" aria­hidden="true">&times;</button> <strong>Error!</strong> <br /> {{ model.errorMessage }} </div> <!--­­ The input fields bound to the model --­­> <div class="well" style="margin-­top: 30px;"> <table style="width: 100%;"> <tr> <td style="width: 45%; text-­align: center;"> <input type="text" placeholder="Phone number (eg; +44 7778 609466)" ng­-model="model.phoneNumber" class="form-­control" style="width: 90%" onkeypress="return checkPhoneInput();" /> </td> <td style="width: 45%; text-­align: center;"> <input type="text" placeholder="Message" ng­-model="model.message" class="form-­control" style="width: 90%" /> </td> <td style="text-­align: center;"> <button class="btn btn-­danger" ng-­click="sendMessage();" ng-­disabled="model.isAjaxInProgress" style="margin­right: 5px;">Send</button> <img src="/Content/ajax-­loader.gif" ng­-show="model.isAjaxInProgress" /> </td> </tr> </table> </div> <!--­­ The past messages ­­--> <div style="margin-­top: 30px;"> <!­­-- The following div is shown if there are no past messages --­­> <div ng­-show="model.allMessages.length == 0"> No messages have been sent yet! </div> <!--­­ The following div is shown if there are some past messages --­­> <div ng-­show="model.allMessages.length == 0"> <table style="width: 100%;" class="table table-­striped"> <tr> <td>Phone Number</td> <td>Message</td> <td></td> </tr> <!--­­ The ng-­repeat directive is line the repeater control in .NET, but as you can see this partial is pure HTML which is much cleaner --> <tr ng-­repeat="message in model.allMessages"> <td>{{ message.to }}</td> <td>{{ message.message }}</td> <td> <button class="btn btn-­danger" ng-­click="delete(message.smsId);" ng­-disabled="model.isAjaxInProgress">Delete</button> </td> </tr> </table> </div> </div> The above code is commented and should be self explanatory. Conditional rendering is achieved through using the ng-­show=”condition” attribute on various div tags. Input fields are bound to the model and the send button is bound to the sendMessage() function in the controller as through the ng­click=”sendMessage()” attribute defined on the button tag. While AJAX calls are taking place, the controller sets model.isAjaxInProgress to true. Based on this variable, buttons are disabled through the ng-­disabled directive which is added as an attribute to the buttons. The ng-­repeat directive added as an attribute to the tr tag causes the table row to be rendered multiple times much like an ASP.NET repeater. 3. Creating the SmsController controller The penultimate piece of our application is the controller which responds to events from our view and interacts with our MVC4 REST WebAPI. The following listing shows the code we need to add to /app/js/controllers.js. Note that controller definitions can be chained. Also note that this controller “asks for” the $http service. The $http service is a simple way in Angular to do AJAX. So far we have only encountered modules, controllers, views and directives in Angular. The $http is new entity in Angular called a service. More information on Angular services can be found at the following URL: http://docs.angularjs.org/guide/dev_guide.services.understanding_services. .controller('SmsController', ['$scope', '$http', function ($scope, $http) { //We define the model $scope.model = {}; //We define the allMessages array in the model //that will contain all the messages sent so far $scope.model.allMessages = []; //The error if any $scope.model.errorMessage = undefined; //We initially load data so set the isAjaxInProgress = true; $scope.model.isAjaxInProgress = true; //Load all the messages $http({ url: '/api/smsresource', method: "GET" }). success(function (data, status, headers, config) { this callback will be called asynchronously //when the response is available $scope.model.allMessages = data; //We are done with AJAX loading $scope.model.isAjaxInProgress = false; }). error(function (data, status, headers, config) { //called asynchronously if an error occurs //or server returns response with an error status. $scope.model.errorMessage = "Error occurred status:" + status; //We are done with AJAX loading $scope.model.isAjaxInProgress = false; }); $scope.delete = function (id) { //We are making an ajax call so we set this to true $scope.model.isAjaxInProgress = true; $http({ url: '/api/smsresource/' + id, method: "DELETE" }). success(function (data, status, headers, config) { // this callback will be called asynchronously // when the response is available $scope.model.allMessages = data; //We are done with AJAX loading $scope.model.isAjaxInProgress = false; }); error(function (data, status, headers, config) { // called asynchronously if an error occurs // or server returns response with an error status. $scope.model.errorMessage = "Error occurred status:" + status; //We are done with AJAX loading $scope.model.isAjaxInProgress = false; }); } $scope.sendMessage = function () { $scope.model.errorMessage = undefined; var message = ''; if($scope.model.message != undefined) message = $scope.model.message.trim(); if ($scope.model.phoneNumber == undefined || $scope.model.phoneNumber == '' || $scope.model.phoneNumber.length < 10 || $scope.model.phoneNumber[0] != '+') { $scope.model.errorMessage = "You must enter a valid phone number in international format. Eg: +44 7778 609466"; return; } if (message.length == 0) { $scope.model.errorMessage = "You must specify a message!"; return; } //We are making an ajax call so we set this to true $scope.model.isAjaxInProgress = true; $http({ url: '/api/smsresource', method: "POST", data: { to: $scope.model.phoneNumber, message: $scope.model.message } }). success(function (data, status, headers, config) { // this callback will be called asynchronously // when the response is available $scope.model.allMessages = data; //We are done with AJAX loading $scope.model.isAjaxInProgress = false; }). error(function (data, status, headers, config) { // called asynchronously if an error occurs // or server returns response with an error status. $scope.model.errorMessage = "Error occurred status:" + status // We are done with AJAX loading $scope.model.isAjaxInProgress = false; }); } }]); We can see from the previous listing how the functions that are called from the view are defined in the controller. It should also be evident how easy it is to make AJAX calls to consume our MVC4 REST WebAPI. Now we are left with the final piece. We need to define a route that associates a particular path with the view we have defined and the controller we have defined. 4. Add a new route that loads the controller and the partial This is the easiest part of the puzzle. We simply define another route in the /app/js/app.js file: $routeProvider.when('/sms', { templateUrl: '/app/partials/smsview.html', controller: 'SmsController' }); Conclusion In this article we have seen how much of the server side functionality in the MVC4 framework can be moved to the browser thus delivering a snappy and fast user interface. We have seen how we can build client side HTML only views that avoid the messy syntax offered by server side Razor views. We have built a functioning app from the ground up. The significant advantage of this approach to building web apps is that the front end can be completely platform independent. Even though we used ASP.NET to create our REST API, we could just easily have used any other language such as Node.js, Ruby etc without changing a single line of our front end code. Angular is a rich framework and we have only touched on basic functionality required to create a SPA.

• iPhone keyboard's return key will move curser to next textfield

  - by iAm

  Hello Fellow Koder ••• I have a TableViewController that is using a grouped Style and has two(2) sections. The first section has 4 rows and the second section has 3 rows. I have placed a UILabel and a UITextField in each cell, and have a custom method(textFieldDone:) to handle the cursor movement to the next text field when the return key is press. This works fine and dandy if there is only one section, but I have two :( and yes I need two:) so I started koden' up an answer, but got results that just don't work, I did notice during my debugging that cell Identifier (I use Two) is only showing the one (in the debug consol) and it's the first one only (Generic Cell). - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = nil; switch (indexPath.section) { case AUTO_DETAILS: { static NSString *cellID = @"GenericCell"; cell = [tableView dequeueReusableCellWithIdentifier:cellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:cellID] autorelease]; UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 75, 25)]; label.tag = kLabelTag; label.font = [UIFont boldSystemFontOfSize:14]; label.textAlignment = UITextAlignmentRight; [cell.contentView addSubview:label]; [label release]; UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(90, 12, 200, 25)]; textField.clearsOnBeginEditing = NO; [textField setDelegate:self]; [textField addTarget:self action:@selector(topTextFieldDone:) forControlEvents:UIControlEventEditingDidEndOnExit]; [cell.contentView addSubview:textField]; } NSInteger row = [indexPath row]; UILabel *label = (UILabel *)[cell viewWithTag:kLabelTag]; UITextField *textField = nil; for (UIView *oneView in cell.contentView.subviews) { if ([oneView isMemberOfClass:[UITextField class]]) textField = (UITextField *)oneView; } label.text = [topCellLabels objectAtIndex:row]; NSNumber *rowAsNum = [[NSNumber alloc] initWithInt:row]; switch (row) { case kMakeRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.make; break; case kModelRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.model; break; case kYearRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.year; break; case kNotesRowIndex: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.notes; break; default: break; } if (textFieldBeingEdited == textField) { textFieldBeingEdited = nil; } textField.tag = row; [rowAsNum release]; break; } case AUTO_REGISTRATION: { static NSString *AutoEditCellID = @"AutoEditCellID"; cell = [tableView dequeueReusableCellWithIdentifier:AutoEditCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:AutoEditCellID] autorelease]; UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 75, 25)]; label.tag = kLabelTag; label.font = [UIFont boldSystemFontOfSize:14]; label.textAlignment = UITextAlignmentRight; [cell.contentView addSubview:label]; [label release]; UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(90, 12, 200, 25)]; textField.clearsOnBeginEditing = NO; [textField setDelegate:self]; [textField addTarget:self action:@selector(bottomTextFieldDone:) forControlEvents:UIControlEventEditingDidEndOnExit]; [cell.contentView addSubview:textField]; } NSInteger row = [indexPath row]; UILabel *label = (UILabel *)[cell viewWithTag:kLabelTag]; UITextField *textField = nil; for (UIView *oneView in cell.contentView.subviews) { if ([oneView isMemberOfClass:[UITextField class]]) textField = (UITextField *)oneView; } label.text = [bottomCellLabels objectAtIndex:row]; NSNumber *rowAsNum = [[NSNumber alloc] initWithInt:row]; switch (row) { case 0: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.vinNumber; break; case 1: if ([[tempValues allKeys] containsObject:rowAsNum]) textField.text = [tempValues objectForKey:rowAsNum]; else textField.text = automobile.policyNumber;

} textField.tag = row; [rowAsNum release]; break; } default: break; } return cell; } Now remember that the first section is working fine and the kode for that method is this: -(IBAction)topTextFieldDone:(id)sender { UITableViewCell *cell = (UITableViewCell *)[[sender superview] superview]; UITableView *table = (UITableView *)[cell superview]; NSIndexPath *textFieldIndexPath = [table indexPathForCell:cell]; NSUInteger row = [textFieldIndexPath row]; row++; if (row > kNumOfEditableRows) row = 0; NSUInteger newIndex[] = {0, row}; NSIndexPath *newPath = [[NSIndexPath alloc] initWithIndexes:newIndex length:2]; UITableViewCell *nextCell = [self.tableView cellForRowAtIndexPath:newPath]; UITextField *nextField = nil; for (UIView *oneView in nextCell.contentView.subviews) { if ([oneView isMemberOfClass:[UITextField class]]) nextField = (UITextField *)oneView; } [nextField becomeFirstResponder]; } It was my idea to just create a second method (secondSectionTextFieldDone:) like this -(IBAction)bottomTextFieldDone:(id)sender { UITableViewCell *cell = (UITableViewCell *)[[sender superview] superview]; UITableView *table = (UITableView *)[cell superview]; NSIndexPath *textFieldIndexPath = [table indexPathForCell:cell]; NSUInteger row = [textFieldIndexPath row]; row++; if (row > 3) row = 0; NSUInteger newIndex[] = {0, row}; NSIndexPath *newPath = [[NSIndexPath alloc] initWithIndexes:newIndex length:2]; UITableViewCell *nextCell = [self.tableView cellForRowAtIndexPath:newPath]; UITextField *nextField = nil; NSString *string = [NSString stringWithFormat:@"AutoEditCellID"]; for (UIView *oneView in nextCell.contentView.subviews) { NSLog(@"%@", nextCell.reuseIdentifier); /* DEBUG LOG */ if ([oneView isMemberOfClass:[UITextField class]] && (nextCell.reuseIdentifier == string)) nextField = (UITextField *)oneView; } [nextField becomeFirstResponder]; } but the result does not solve the issue. so my question is, how can i get the cursor to jump to the next textfield in the section that it is in, If there is one, and if not, then send a message "resignFirstResponder" so that, the keyboard goes away.

• Table sorting & pagination with jQuery and Razor in ASP.NET MVC

  - by hajan

  Introduction jQuery enjoys living inside pages which are built on top of ASP.NET MVC Framework. The ASP.NET MVC is a place where things are organized very well and it is quite hard to make them dirty, especially because the pattern enforces you on purity (you can still make it dirty if you want so ;) ). We all know how easy is to build a HTML table with a header row, footer row and table rows showing some data. With ASP.NET MVC we can do this pretty easy, but, the result will be pure HTML table which only shows data, but does not includes sorting, pagination or some other advanced features that we were used to have in the ASP.NET WebForms GridView. Ok, there is the WebGrid MVC Helper, but what if we want to make something from pure table in our own clean style? In one of my recent projects, I’ve been using the jQuery tablesorter and tablesorter.pager plugins that go along. You don’t need to know jQuery to make this work… You need to know little CSS to create nice design for your table, but of course you can use mine from the demo… So, what you will see in this blog is how to attach this plugin to your pure html table and a div for pagination and make your table with advanced sorting and pagination features.   Demo Project Resources The resources I’m using for this demo project are shown in the following solution explorer window print screen: Content/images – folder that contains all the up/down arrow images, pagination buttons etc. You can freely replace them with your own, but keep the names the same if you don’t want to change anything in the CSS we will built later. Content/Site.css – The main css theme, where we will add the theme for our table too Controllers/HomeController.cs – The controller I’m using for this project Models/Person.cs – For this demo, I’m using Person.cs class Scripts – jquery-1.4.4.min.js, jquery.tablesorter.js, jquery.tablesorter.pager.js – required script to make the magic happens Views/Home/Index.cshtml – Index view (razor view engine) the other items are not important for the demo. ASP.NET MVC 1. Model In this demo I use only one Person class which defines Person entity with several properties. You can use your own model, maybe one which will access data from database or any other resource. Person.cs public class Person {     public string Name { get; set; }     public string Surname { get; set; }     public string Email { get; set; }     public int? Phone { get; set; }     public DateTime? DateAdded { get; set; }     public int? Age { get; set; }     public Person(string name, string surname, string email,         int? phone, DateTime? dateadded, int? age)     {         Name = name;         Surname = surname;         Email = email;         Phone = phone;         DateAdded = dateadded;         Age = age;     } } 2. View In our example, we have only one Index.chtml page where Razor View engine is used. Razor view engine is my favorite for ASP.NET MVC because it’s very intuitive, fluid and keeps your code clean. 3. Controller Since this is simple example with one page, we use one HomeController.cs where we have two methods, one of ActionResult type (Index) and another GetPeople() used to create and return list of people. HomeController.cs public class HomeController : Controller {     //     // GET: /Home/     public ActionResult Index()     {         ViewBag.People = GetPeople();         return View();     }     public List<Person> GetPeople()     {         List<Person> listPeople = new List<Person>();                  listPeople.Add(new Person("Hajan", "Selmani", "[email protected]", 070070070,DateTime.Now, 25));                     listPeople.Add(new Person("Straight", "Dean", "[email protected]", 123456789, DateTime.Now.AddDays(-5), 35));         listPeople.Add(new Person("Karsen", "Livia", "[email protected]", 46874651, DateTime.Now.AddDays(-2), 31));         listPeople.Add(new Person("Ringer", "Anne", "[email protected]", null, DateTime.Now, null));         listPeople.Add(new Person("O'Leary", "Michael", "[email protected]", 32424344, DateTime.Now, 44));         listPeople.Add(new Person("Gringlesby", "Anne", "[email protected]", null, DateTime.Now.AddDays(-9), 18));         listPeople.Add(new Person("Locksley", "Stearns", "[email protected]", 2135345, DateTime.Now, null));         listPeople.Add(new Person("DeFrance", "Michel", "[email protected]", 235325352, DateTime.Now.AddDays(-18), null));         listPeople.Add(new Person("White", "Johnson", null, null, DateTime.Now.AddDays(-22), 55));         listPeople.Add(new Person("Panteley", "Sylvia", null, 23233223, DateTime.Now.AddDays(-1), 32));         listPeople.Add(new Person("Blotchet-Halls", "Reginald", null, 323243423, DateTime.Now, 26));         listPeople.Add(new Person("Merr", "South", "[email protected]", 3232442, DateTime.Now.AddDays(-5), 85));         listPeople.Add(new Person("MacFeather", "Stearns", "[email protected]", null, DateTime.Now, null));         return listPeople;     } }   TABLE CSS/HTML DESIGN Now, lets start with the implementation. First of all, lets create the table structure and the main CSS. 1. HTML Structure @{     Layout = null;     } <!DOCTYPE html> <html> <head>     <title>ASP.NET & jQuery</title>     <!-- referencing styles, scripts and writing custom js scripts will go here --> </head> <body>     <div>         <table class="tablesorter">             <thead>                 <tr>                     <th> value </th>                 </tr>             </thead>             <tbody>                 <tr>                     <td>value</td>                 </tr>             </tbody>             <tfoot>                 <tr>                     <th> value </th>                 </tr>             </tfoot>         </table>         <div id="pager">                      </div>     </div> </body> </html> So, this is the main structure you need to create for each of your tables where you want to apply the functionality we will create. Of course the scripts are referenced once ;). As you see, our table has class tablesorter and also we have a div with id pager. In the next steps we will use both these to create the needed functionalities. The complete Index.cshtml coded to get the data from controller and display in the page is: <body>     <div>         <table class="tablesorter">             <thead>                 <tr>                     <th>Name</th>                     <th>Surname</th>                     <th>Email</th>                     <th>Phone</th>                     <th>Date Added</th>                 </tr>             </thead>             <tbody>                 @{                     foreach (var p in ViewBag.People)                     {                                 <tr>                         <td>@p.Name</td>                         <td>@p.Surname</td>                         <td>@p.Email</td>                         <td>@p.Phone</td>                         <td>@p.DateAdded</td>                     </tr>                     }                 }             </tbody>             <tfoot>                 <tr>                     <th>Name</th>                     <th>Surname</th>                     <th>Email</th>                     <th>Phone</th>                     <th>Date Added</th>                 </tr>             </tfoot>         </table>         <div id="pager" style="position: none;">             <form>             <img src="@Url.Content("~/Content/images/first.png")" class="first" />             <img src="@Url.Content("~/Content/images/prev.png")" class="prev" />             <input type="text" class="pagedisplay" />             <img src="@Url.Content("~/Content/images/next.png")" class="next" />             <img src="@Url.Content("~/Content/images/last.png")" class="last" />             <select class="pagesize">                 <option selected="selected" value="5">5</option>                 <option value="10">10</option>                 <option value="20">20</option>                 <option value="30">30</option>                 <option value="40">40</option>             </select>             </form>         </div>     </div> </body> So, mainly the structure is the same. I have added @Razor code to create table with data retrieved from the ViewBag.People which has been filled with data in the home controller. 2. CSS Design The CSS code I’ve created is: /* DEMO TABLE */ body {     font-size: 75%;     font-family: Verdana, Tahoma, Arial, "Helvetica Neue", Helvetica, Sans-Serif;     color: #232323;     background-color: #fff; } table { border-spacing:0; border:1px solid gray;} table.tablesorter thead tr .header {     background-image: url(images/bg.png);     background-repeat: no-repeat;     background-position: center right;     cursor: pointer; } table.tablesorter tbody td {     color: #3D3D3D;     padding: 4px;     background-color: #FFF;     vertical-align: top; } table.tablesorter tbody tr.odd td {     background-color:#F0F0F6; } table.tablesorter thead tr .headerSortUp {     background-image: url(images/asc.png); } table.tablesorter thead tr .headerSortDown {     background-image: url(images/desc.png); } table th { width:150px;            border:1px outset gray;            background-color:#3C78B5;            color:White;            cursor:pointer; } table thead th:hover { background-color:Yellow; color:Black;} table td { width:150px; border:1px solid gray;} PAGINATION AND SORTING Now, when everything is ready and we have the data, lets make pagination and sorting functionalities 1. jQuery Scripts referencing <link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" /> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.tablesorter.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.tablesorter.pager.js")" type="text/javascript"></script> 2. jQuery Sorting and Pagination script   <script type="text/javascript">     $(function () {         $("table.tablesorter").tablesorter({ widthFixed: true, sortList: [[0, 0]] })         .tablesorterPager({ container: $("#pager"), size: $(".pagesize option:selected").val() });     }); </script> So, with only two lines of code, I’m using both tablesorter and tablesorterPager plugins, giving some options to both these. Options added: tablesorter - widthFixed: true – gives fixed width of the columns tablesorter - sortList[[0,0]] – An array of instructions for per-column sorting and direction in the format: [[columnIndex, sortDirection], ... ] where columnIndex is a zero-based index for your columns left-to-right and sortDirection is 0 for Ascending and 1 for Descending. A valid argument that sorts ascending first by column 1 and then column 2 looks like: [[0,0],[1,0]] (source: http://tablesorter.com/docs/) tablesorterPager – container: $(“#pager”) – tells the pager container, the div with id pager in our case. tablesorterPager – size: the default size of each page, where I get the default value selected, so if you put selected to any other of the options in your select list, you will have this number of rows as default per page for the table too. END RESULTS 1. Table once the page is loaded (default results per page is 5 and is automatically sorted by 1st column as sortList is specified) 2. Sorted by Phone Descending 3. Changed pagination to 10 items per page 4. Sorted by Phone and Name (use SHIFT to sort on multiple columns) 5. Sorted by Date Added 6. Page 3, 5 items per page   ADDITIONAL ENHANCEMENTS We can do additional enhancements to the table. We can make search for each column. I will cover this in one of my next blogs. Stay tuned. DEMO PROJECT You can download demo project source code from HERE.CONCLUSION Once you finish with the demo, run your page and open the source code. You will be amazed of the purity of your code.Working with pagination in client side can be very useful. One of the benefits is performance, but if you have thousands of rows in your tables, you will get opposite result when talking about performance. Hence, sometimes it is nice idea to make pagination on back-end. So, the compromise between both approaches would be best to combine both of them. I use at most up to 500 rows on client-side and once the user reach the last page, we can trigger ajax postback which can get the next 500 rows using server-side pagination of the same data. I would like to recommend the following blog post http://weblogs.asp.net/gunnarpeipman/archive/2010/09/14/returning-paged-results-from-repositories-using-pagedresult-lt-t-gt.aspx, which will help you understand how to return page results from repository. I hope this was helpful post for you. Wait for my next posts ;). Please do let me know your feedback. Best Regards, Hajan

• Web Browser Control &ndash; Specifying the IE Version

  - by Rick Strahl

  I use the Internet Explorer Web Browser Control in a lot of my applications to display document type layout. HTML happens to be one of the most common document formats and displaying data in this format – even in desktop applications, is often way easier than using normal desktop technologies. One issue the Web Browser Control has that it’s perpetually stuck in IE 7 rendering mode by default. Even though IE 8 and now 9 have significantly upgraded the IE rendering engine to be more CSS and HTML compliant by default the Web Browser control will have none of it. IE 9 in particular – with its much improved CSS support and basic HTML 5 support is a big improvement and even though the IE control uses some of IE’s internal rendering technology it’s still stuck in the old IE 7 rendering by default. This applies whether you’re using the Web Browser control in a WPF application, a WinForms app, a FoxPro or VB classic application using the ActiveX control. Behind the scenes all these UI platforms use the COM interfaces and so you’re stuck by those same rules. Rendering Challenged To see what I’m talking about here are two screen shots rendering an HTML 5 doctype page that includes some CSS 3 functionality – rounded corners and border shadows - from an earlier post. One uses IE 9 as a standalone browser, and one uses a simple WPF form that includes the Web Browser control. IE 9 Browser:   Web Browser control in a WPF form: The IE 9 page displays this HTML correctly – you see the rounded corners and shadow displayed. Obviously the latter rendering using the Web Browser control in a WPF application is a bit lacking. Not only are the new CSS features missing but the page also renders in Internet Explorer’s quirks mode so all the margins, padding etc. behave differently by default, even though there’s a CSS reset applied on this page. If you’re building an application that intends to use the Web Browser control for a live preview of some HTML this is clearly undesirable. Feature Delegation via Registry Hacks Fortunately starting with Internet Explore 8 and later there’s a fix for this problem via a registry setting. You can specify a registry key to specify which rendering mode and version of IE should be used by that application. These are not global mind you – they have to be enabled for each application individually. There are two different sets of keys for 32 bit and 64 bit applications. 32 bit: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION Value Key: yourapplication.exe 64 bit: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION Value Key: yourapplication.exe The value to set this key to is (taken from MSDN here) as decimal values: 9999 (0x270F) Internet Explorer 9. Webpages are displayed in IE9 Standards mode, regardless of the !DOCTYPE directive. 9000 (0x2328) Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. 8888 (0x22B8) Webpages are displayed in IE8 Standards mode, regardless of the !DOCTYPE directive. 8000 (0x1F40) Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. 7000 (0x1B58) Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode.   The added key looks something like this in the Registry Editor: With this in place my Html Html Help Builder application which has wwhelp.exe as its main executable now works with HTML 5 and CSS 3 documents in the same way that Internet Explorer 9 does. Incidentally I accidentally added an ‘empty’ DWORD value of 0 to my EXE name and that worked as well giving me IE 9 rendering. Although not documented I suspect 0 (or an invalid value) will default to the installed browser. Don’t have a good way to test this but if somebody could try this with IE 8 installed that would be great: What happens when setting 9000 with IE 8 installed? What happens when setting 0 with IE 8 installed? Don’t forget to add Keys for Host Environments If you’re developing your application in Visual Studio and you run the debugger you may find that your application is still not rendering right, but if you run the actual generated EXE from Explorer or the OS command prompt it works. That’s because when you run the debugger in Visual Studio it wraps your application into a debugging host container. For this reason you might want to also add another registry key for yourapp.vshost.exe on your development machine. If you’re developing in Visual FoxPro make sure you add a key for vfp9.exe to see the rendering adjustments in the Visual FoxPro development environment. Cleaner HTML - no more HTML mangling! There are a number of additional benefits to setting up rendering of the Web Browser control to the IE 9 engine (or even the IE 8 engine) beyond the obvious rendering functionality. IE 9 actually returns your HTML in something that resembles the original HTML formatting, as opposed to the IE 7 default format which mangled the original HTML content. If you do the following in the WPF application: private void button2_Click(object sender, RoutedEventArgs e) { dynamic doc = this.webBrowser.Document; MessageBox.Show(doc.body.outerHtml); } you get different output depending on the rendering mode active. With the default IE 7 rendering you get: <BODY><DIV> <H1>Rounded Corners and Shadows - Creating Dialogs in CSS</H1> <DIV class=toolbarcontainer><A class=hoverbutton href="./"><IMG src="../../css/images/home.gif"> Home</A> <A class=hoverbutton href="RoundedCornersAndShadows.htm"><IMG src="../../css/images/refresh.gif"> Refresh</A> </DIV> <DIV class=containercontent> <FIELDSET><LEGEND>Plain Box</LEGEND><!-- Simple Box with rounded corners and shadow --> <DIV style="BORDER-BOTTOM: steelblue 2px solid;

                    return true;  // true closes - false leaves open                 }             });     }); </SCRIPT> </DIV></BODY> Now lest you think I’m out of my mind and create complete whacky HTML rooted in the last century, here’s the IE 9 rendering mode output which looks a heck of a lot cleaner and a lot closer to my original HTML of the page I’m accessing: <body> <div>         <h1>Rounded Corners and Shadows - Creating Dialogs in CSS</h1>     <div class="toolbarcontainer">         <a class="hoverbutton" href="./"> <img src="../../css/images/home.gif"> Home</a>         <a class="hoverbutton" href="RoundedCornersAndShadows.htm"> <img src="../../css/images/refresh.gif"> Refresh</a>     </div>         <div class="containercontent">     <fieldset>         <legend>Plain Box</legend>                <!-- Simple Box with rounded corners and shadow -->             <div style="border: 2px solid steelblue;

                    return true;  // true closes - false leaves open                 }             });     }); </script>        </div> </body> IOW, in IE9 rendering mode IE9 is much closer (but not identical) to the original HTML from the page on the Web that we’re reading from. As a side note: Unfortunately, the browser feature emulation can't be applied against the Html Help (CHM) Engine in Windows which uses the Web Browser control (or COM interfaces anyway) to render Html Help content. I tried setting up hh.exe which is the help viewer, to use IE 9 rendering but a help file generated with CSS3 features will simply show in IE 7 mode. Bummer - this would have been a nice quick fix to allow help content served from CHM files to look better. HTML Editing leaves HTML formatting intact In the same vane, if you do any inline HTML editing in the control by setting content to be editable, IE 9’s control does a much more reasonable job of creating usable and somewhat valid HTML. It also leaves the original content alone other than the text your are editing or adding. No longer is the HTML output stripped of excess spaces and reformatted in IEs format. So if I do: private void button3_Click(object sender, RoutedEventArgs e) { dynamic doc = this.webBrowser.Document; doc.body.contentEditable = true; } and then make some changes to the document by typing into it using IE 9 mode, the document formatting stays intact and only the affected content is modified. The created HTML is reasonably clean (although it does lack proper XHTML formatting for things like <br/> <hr/>). This is very different from IE 7 mode which mangled the HTML as soon as the page was loaded into the control. Any editing you did stripped out all white space and lost all of your existing XHTML formatting. In IE 9 mode at least *most* of your original formatting stays intact. This is huge! In Html Help Builder I have supported HTML editing for a long time but the HTML mangling by the Web Browser control made it very difficult to edit the HTML later. Previously IE would mangle the HTML by stripping out spaces, upper casing all tags and converting many XHTML safe tags to its HTML 3 tags. Now IE leaves most of my document alone while editing, and creates cleaner and more compliant markup (with exception of self-closing elements like BR/HR). The end result is that I now have HTML editing in place that's much cleaner and actually capable of being manually edited. Caveats, Caveats, Caveats It wouldn't be Internet Explorer if there weren't some major compatibility issues involved in using this various browser version interaction. The biggest thing I ran into is that there are odd differences in some of the COM interfaces and what they return. I specifically ran into a problem with the document.selection.createRange() function which with IE 7 compatibility returns an expected text range object. When running in IE 8 or IE 9 mode however. I could not retrieve a valid text range with this code where loEdit is the WebBrowser control: loRange = loEdit.document.selection.CreateRange() The loRange object returned (here in FoxPro) had a length property of 0 but none of the other properties of the TextRange or TextRangeCollection objects were available. I figured this was due to some changed security settings but even after elevating the Intranet Security Zone and mucking with the other browser feature flags pertaining to security I had no luck. In the end I relented and used a JavaScript function in my editor document that returns a selection range object: function getselectionrange() { var range = document.selection.createRange(); return range; } and call that JavaScript function from my host applications code: *** Use a function in the document to get around HTML Editing issues loRange = loEdit.document.parentWindow.getselectionrange(.f.) and that does work correctly. This wasn't a big deal as I'm already loading a support script file into the editor page so all I had to do is add the function to this existing script file. You can find out more how to call script code in the Web Browser control from a host application in a previous post of mine. IE 8 and 9 also clamp down the security environment a little more than the default IE 7 control, so there may be other issues you run into. Other than the createRange() problem above I haven't seen anything else that is breaking in my code so far though and that's encouraging at least since it uses a lot of HTML document manipulation for the custom editor I've created (and would love to replace - any PROFESSIONAL alternatives anybody?) Registry Key Installation for your Application It’s important to remember that this registry setting is made per application, so most likely this is something you want to set up with your installer. Also remember that 32 and 64 bit settings require separate settings in the registry so if you’re creating your installer you most likely will want to set both keys in the registry preemptively for your application. I use Tarma Installer for all of my application installs and in Tarma I configure registry keys for both and set a flag to only install the latter key group in the 64 bit version: Because this setting is application specific you have to do this for every application you install unfortunately, but this also means that you can safely configure this setting in the registry because it is after only applied to your application. Another problem with install based installation is version detection. If IE 8 is installed I’d want 8000 for the value, if IE 9 is installed I want 9000. I can do this easily in code but in the installer this is much more difficult. I don’t have a good solution for this at the moment, but given that the app works with IE 7 mode now, IE 9 mode is just a bonus for the moment. If IE 9 is not installed and 9000 is used the default rendering will remain in use.   It sure would be nice if we could specify the IE rendering mode as a property, but I suspect the ActiveX container has to know before it loads what actual version to load up and once loaded can only load a single version of IE. This would account for this annoying application level configuration… Summary The registry feature emulation has been available for quite some time, but I just found out about it today and started experimenting around with it. I’m stoked to see that this is available as I’d pretty much given up in ever seeing any better rendering in the Web Browser control. Now at least my apps can take advantage of newer HTML features. Now if we could only get better HTML Editing support somehow <snicker>… ah can’t have everything.© Rick Strahl, West Wind Technologies, 2005-2011Posted in .NET  FoxPro  Windows

• Why is my WCF Rest Service on IIS7 Authenticating TWICE!?!?

  - by TheAggie

  Ok, if someone could shed some light on this for me, I would greatly appreciate it. So here we go. I had a rest service running fine the other day but after I accidentally overwrote the web.config all hell broke loose. I've spent the past day and a half trying to sort things out but I can't seem to figure out what is missing or misplaced. So, I've designed this service around WCF Rest Contrib (http://wcfrestcontrib.codeplex.com)'s authentication process. Now, I can get this working fine on my localhost w/ the current web.config (minus the endpoint entry) but once I upload it to discountasp and select "basic authorization" in the ISS7 Manager, it appears that I'm getting authenticated twice! Once using my discount asp.net user/pass and then the next time using the application user/pass. Unfortunately I only provide one set of credentials and don't want to hard code my discountasp account info into the app. Like I said before, this worked fine a few days ago.

I thought this was strange, so I looked at fiddler and saw something interesting. Whenever I try request a procedure with [OperationAuthentication] defined and provide my discountasp.net username/pass I get two different "WWW-Authenticate" headers back in Fiddler: WWW-Authenticate: Basic realm="MyRESTServiceRealm" WWW-Authenticate: Basic realm="www.mydomain.com" On the other hand, if I try to access the same procedures with only my application's user/pass, I only get the site's header: WWW-Authenticate: Basic realm="www.mydomain.com" My hypothesis is that for some reason I'm having to pass through the default "Basic Authorization" layer set by IIS before I can get to the application's "Custom Basic Authorization" layer. After verifying this by created an identical user/pass for my service that I use for my discountasp.net account, I was able to successfully pass both layers of authentication without any issues... so I think I can conclude that this is indeed the issue. Now how do I disable the default one? Do I need to do this in the IIS Manager, or in the web.config? Anyway, I have absolutely no idea how this is possible or what I need to do to resolve the issue, but I know that something is seriously out of whack. Any suggestions would be greatly appreciated! Thanks.

• Automating Solaris 11 Zones Installation Using The Automated Install Server

  - by Orgad Kimchi

  Introduction How to use the Oracle Solaris 11 Automated install server in order to automate the Solaris 11 Zones installation. In this document I will demonstrate how to setup the Automated Install server in order to provide hands off installation process for the Global Zone and two Non Global Zones located on the same system. Architecture layout: Figure 1. Architecture layout Prerequisite Setup the Automated install server (AI) using the following instructions “How to Set Up Automated Installation Services for Oracle Solaris 11” The first step in this setup will be creating two Solaris 11 Zones configuration files. Step 1: Create the Solaris 11 Zones configuration files  The Solaris Zones configuration files should be in the format of the zonecfg export command. # zonecfg -z zone1 export > /var/tmp/zone1# cat /var/tmp/zone1 create -b set brand=solaris set zonepath=/rpool/zones/zone1 set autoboot=true set ip-type=exclusive add anet set linkname=net0 set lower-link=auto set configure-allowed-address=true set link-protection=mac-nospoof set mac-address=random end  Create a backup copy of this file under a different name, for example, zone2. # cp /var/tmp/zone1 /var/tmp/zone2 Modify the second configuration file with the zone2 configuration information You should change the zonepath for example: set zonepath=/rpool/zones/zone2 Step2: Copy and share the Zones configuration files  Create the NFS directory for the Zones configuration files # mkdir /export/zone_config Share the directory for the Zones configuration file # share –o ro /export/zone_config Copy the Zones configuration files into the NFS shared directory # cp /var/tmp/zone1 /var/tmp/zone2  /export/zone_config Verify that the NFS share has been created using the following command # share export_zone_config      /export/zone_config     nfs     sec=sys,ro Step 3: Add the Global Zone as client to the Install Service Use the installadm create-client command to associate client (Global Zone) with the install service To find the MAC address of a system, use the dladm command as described in the dladm(1M) man page. The following command adds the client (Global Zone) with MAC address 0:14:4f:2:a:19 to the s11x86service install service. # installadm create-client -e “0:14:4f:2:a:19" -n s11x86service You can verify the client creation using the following command # installadm list –c Service Name  Client Address     Arch   Image Path ------------  --------------     ----   ---------- s11x86service 00:14:4F:02:0A:19  i386   /export/auto_install/s11x86service We can see the client install service name (s11x86service), MAC address (00:14:4F:02:0A:19 and Architecture (i386). Step 4: Global Zone manifest setup  First, get a list of the installation services and the manifests associated with them: # installadm list -m Service Name   Manifest        Status ------------   --------        ------ default-i386   orig_default   Default s11x86service  orig_default   Default Then probe the s11x86service and the default manifest associated with it. The -m switch reflects the name of the manifest associated with a service. Since we want to capture that output into a file, we redirect the output of the command as follows: # installadm export -n s11x86service -m orig_default >  /var/tmp/orig_default.xml Create a backup copy of this file under a different name, for example, orig-default2.xml, and edit the copy. # cp /var/tmp/orig_default.xml /var/tmp/orig_default2.xml Use the configuration element in the AI manifest for the client system to specify non-global zones. Use the name attribute of the configuration element to specify the name of the zone. Use the source attribute to specify the location of the config file for the zone.The source location can be any http:// or file:// location that the client can access during installation. The following sample AI manifest specifies two Non-Global Zones: zone1 and zone2 You should replace the server_ip with the ip address of the NFS server. <!DOCTYPE auto_install SYSTEM "file:///usr/share/install/ai.dtd.1"> <auto_install>   <ai_instance>     <target>       <logical>         <zpool name="rpool" is_root="true">           <filesystem name="export" mountpoint="/export"/>           <filesystem name="export/home"/>           <be name="solaris"/>         </zpool>       </logical>     </target>     <software type="IPS">       <source>         <publisher name="solaris">           <origin name="http://pkg.oracle.com/solaris/release"/>         </publisher>       </source>       <software_data action="install">         <name>pkg:/entire@latest</name>         <name>pkg:/group/system/solaris-large-server</name>       </software_data>     </software>     <configuration type="zone" name="zone1" source="file:///net/server_ip/export/zone_config/zone1"/>     <configuration type="zone" name="zone2" source="file:///net/server_ip/export/zone_config/zone2"/>   </ai_instance> </auto_install> The following example adds the /var/tmp/orig_default2.xml AI manifest to the s11x86service install service # installadm create-manifest -n s11x86service -f /var/tmp/orig_default2.xml -m gzmanifest You can verify the manifest creation using the following command # installadm list -n s11x86service  -m Service/Manifest Name  Status   Criteria ---------------------  ------   -------- s11x86service    orig_default        Default  None    gzmanifest          Inactive None We can see from the command output that the new manifest named gzmanifest has been created and associated with the s11x86service install service. Step 5: Non Global Zone manifest setup The AI manifest for non-global zone installation is similar to the AI manifest for installing the global zone. If you do not provide a custom AI manifest for a non-global zone, the default AI manifest for Zones is used The default AI manifest for Zones is available at /usr/share/auto_install/manifest/zone_default.xml. In this example we should use the default AI manifest for zones The following sample default AI manifest for zones # cat /usr/share/auto_install/manifest/zone_default.xml <?xml version="1.0" encoding="UTF-8"?> <!--  Copyright (c) 2011, 2012, Oracle and/or its affiliates. All rights reserved. --> <!DOCTYPE auto_install SYSTEM "file:///usr/share/install/ai.dtd.1"> <auto_install>     <ai_instance name="zone_default">         <target>             <logical>                 <zpool name="rpool">                     <!--                       Subsequent <filesystem> entries instruct an installer                       to create following ZFS datasets:                           <root_pool>/export         (mounted on /export)                           <root_pool>/export/home    (mounted on /export/home)                       Those datasets are part of standard environment                       and should be always created.                       In rare cases, if there is a need to deploy a zone                       without these datasets, either comment out or remove                       <filesystem> entries. In such scenario, it has to be also                       assured that in case of non-interactive post-install                       configuration, creation of initial user account is                       disabled in related system configuration profile.                       Otherwise the installed zone would fail to boot.                     -->                     <filesystem name="export" mountpoint="/export"/>                     <filesystem name="export/home"/>                     <be name="solaris">                         <options>                             <option name="compression" value="on"/>                         </options>                     </be>                 </zpool>             </logical>         </target>         <software type="IPS">             <destination>                 <image>                     <!-- Specify locales to install -->                     <facet set="false">facet.locale.*</facet>                     <facet set="true">facet.locale.de</facet>                     <facet set="true">facet.locale.de_DE</facet>                     <facet set="true">facet.locale.en</facet>                     <facet set="true">facet.locale.en_US</facet>                     <facet set="true">facet.locale.es</facet>                     <facet set="true">facet.locale.es_ES</facet>                     <facet set="true">facet.locale.fr</facet>                     <facet set="true">facet.locale.fr_FR</facet>                     <facet set="true">facet.locale.it</facet>                     <facet set="true">facet.locale.it_IT</facet>                     <facet set="true">facet.locale.ja</facet>                     <facet set="true">facet.locale.ja_*</facet>                     <facet set="true">facet.locale.ko</facet>                     <facet set="true">facet.locale.ko_*</facet>                     <facet set="true">facet.locale.pt</facet>                     <facet set="true">facet.locale.pt_BR</facet>                     <facet set="true">facet.locale.zh</facet>                     <facet set="true">facet.locale.zh_CN</facet>                     <facet set="true">facet.locale.zh_TW</facet>                 </image>             </destination>             <software_data action="install">                 <name>pkg:/group/system/solaris-small-server</name>             </software_data>         </software>     </ai_instance> </auto_install> (optional) We can customize the default AI manifest for Zones Create a backup copy of this file under a different name, for example, zone_default2.xml and edit the copy # cp /usr/share/auto_install/manifest/zone_default.xml /var/tmp/zone_default2.xml Edit the copy (/var/tmp/zone_default2.xml) The following example adds the /var/tmp/zone_default2.xml AI manifest to the s11x86service install service and specifies that zone1 and zone2 should use this manifest. # installadm create-manifest -n s11x86service -f /var/tmp/zone_default2.xml -m zones_manifest -c zonename="zone1 zone2" Note: Do not use the following elements or attributes in a non-global zone AI manifest:     The auto_reboot attribute of the ai_instance element     The http_proxy attribute of the ai_instance element     The disk child element of the target element     The noswap attribute of the logical element     The nodump attribute of the logical element     The configuration element Step 6: Global Zone profile setup We are going to create a global zone configuration profile which includes the host information for example: host name, ip address name services etc… # sysconfig create-profile –o /var/tmp/gz_profile.xml You need to provide the host information for example:     Default router     Root password     DNS information The output should eventually disappear and be replaced by the initial screen of the System Configuration Tool (see Figure 2), where you can do the final configuration. Figure 2. Profile creation menu You can validate the profile using the following command # installadm validate -n s11x86service –P /var/tmp/gz_profile.xml Validating static profile gz_profile.xml...  Passed Next, instantiate a profile with the install service. In our case, use the following syntax for doing this # installadm create-profile -n s11x86service  -f /var/tmp/gz_profile.xml -p  gz_profile You can verify profile creation using the following command # installadm list –n s11x86service  -p Service/Profile Name  Criteria --------------------  -------- s11x86service    gz_profile         None We can see that the gz_profie has been created and associated with the s11x86service Install service. Step 7: Setup the Solaris Zones configuration profiles The step should be similar to the Global zone profile creation on step 6 # sysconfig create-profile –o /var/tmp/zone1_profile.xml # sysconfig create-profile –o /var/tmp/zone2_profile.xml You can validate the profiles using the following command # installadm validate -n s11x86service -P /var/tmp/zone1_profile.xml Validating static profile zone1_profile.xml...  Passed # installadm validate -n s11x86service -P /var/tmp/zone2_profile.xml Validating static profile zone2_profile.xml...  Passed Next, associate the profiles with the install service The following example adds the zone1_profile.xml configuration profile to the s11x86service  install service and specifies that zone1 should use this profile. # installadm create-profile -n s11x86service  -f  /var/tmp/zone1_profile.xml -p zone1_profile -c zonename=zone1 The following example adds the zone2_profile.xml configuration profile to the s11x86service  install service and specifies that zone2 should use this profile. # installadm create-profile -n s11x86service  -f  /var/tmp/zone2_profile.xml -p zone2_profile -c zonename=zone2 You can verify the profiles creation using the following command # installadm list -n s11x86service -p Service/Profile Name  Criteria --------------------  -------- s11x86service    zone1_profile      zonename = zone1    zone2_profile      zonename = zone2    gz_profile         None We can see that we have three profiles in the s11x86service  install service     Global Zone  gz_profile     zone1            zone1_profile     zone2            zone2_profile. Step 8: Global Zone setup Associate the global zone client with the manifest and the profile that we create in the previous steps The following example adds the manifest and profile to the client (global zone), where: gzmanifest  is the name of the manifest. gz_profile  is the name of the configuration profile. mac="0:14:4f:2:a:19" is the client (global zone) mac address s11x86service is the install service name. # installadm set-criteria -m  gzmanifest  –p  gz_profile  -c mac="0:14:4f:2:a:19" -n s11x86service You can verify the manifest and profile association using the following command # installadm list -n s11x86service -p  -m Service/Manifest Name  Status   Criteria ---------------------  ------   -------- s11x86service    gzmanifest                   mac  = 00:14:4F:02:0A:19    orig_default        Default  None Service/Profile Name  Criteria --------------------  -------- s11x86service    gz_profile         mac      = 00:14:4F:02:0A:19    zone2_profile      zonename = zone2    zone1_profile      zonename = zone1 Step 9: Provision the host with the Non-Global Zones The next step is to boot the client system off the network and provision it using the Automated Install service that we just set up. First, boot the client system. Figure 3 shows the network boot attempt (when done on an x86 system): Figure 3. Network Boot Then you will be prompted by a GRUB menu, with a timer, as shown in Figure 4. The default selection (the "Text Installer and command line" option) is highlighted.  Press the down arrow to highlight the second option labeled Automated Install, and then press Enter. The reason we need to do this is because we want to prevent a system from being automatically re-installed if it were to be booted from the network accidentally. Figure 4. GRUB Menu What follows is the continuation of a networked boot from the Automated Install server,. The client downloads a mini-root (a small set of files in which to successfully run the installer), identifies the location of the Automated Install manifest on the network, retrieves that manifest, and then processes it to identify the address of the IPS repository from which to obtain the desired software payload. Non-Global Zones are installed and configured on the first reboot after the Global Zone is installed. You can list all the Solaris Zones status using the following command # zoneadm list -civ Once the Zones are in running state you can login into the Zone using the following command # zlogin –z zone1 Troubleshooting Automated Installations If an installation to a client system failed, you can find the client log at /system/volatile/install_log. NOTE: Zones are not installed if any of the following errors occurs:     A zone config file is not syntactically correct.     A collision exists among zone names, zone paths, or delegated ZFS datasets in the set of zones to be installed     Required datasets are not configured in the global zone. For more troubleshooting information see “Installing Oracle Solaris 11 Systems” Conclusion This paper demonstrated the benefits of using the Automated Install server to simplify the Non Global Zones setup, including the creation and configuration of the global zone manifest and the Solaris Zones profiles.

• OBJ model loaded in LWJGL has a black area with no texture

  - by gambiting

  I have a problem with loading an .obj file in LWJGL and its textures. The object is a tree(it's a paid model from TurboSquid, so I can't post it here,but here's the link if you want to see how it should look like): http://www.turbosquid.com/FullPreview/Index.cfm/ID/701294 I wrote a custom OBJ loader using the LWJGL tutorial from their wiki. It looks like this: public class OBJLoader { public static Model loadModel(File f) throws FileNotFoundException, IOException { BufferedReader reader = new BufferedReader(new FileReader(f)); Model m = new Model(); String line; Texture currentTexture = null; while((line=reader.readLine()) != null) { if(line.startsWith("v ")) { float x = Float.valueOf(line.split(" ")[1]); float y = Float.valueOf(line.split(" ")[2]); float z = Float.valueOf(line.split(" ")[3]); m.verticies.add(new Vector3f(x,y,z)); }else if(line.startsWith("vn ")) { float x = Float.valueOf(line.split(" ")[1]); float y = Float.valueOf(line.split(" ")[2]); float z = Float.valueOf(line.split(" ")[3]); m.normals.add(new Vector3f(x,y,z)); }else if(line.startsWith("vt ")) { float x = Float.valueOf(line.split(" ")[1]); float y = Float.valueOf(line.split(" ")[2]); m.texVerticies.add(new Vector2f(x,y)); }else if(line.startsWith("f ")) { Vector3f vertexIndicies = new Vector3f(Float.valueOf(line.split(" ")[1].split("/")[0]), Float.valueOf(line.split(" ")[2].split("/")[0]), Float.valueOf(line.split(" ")[3].split("/")[0])); Vector3f textureIndicies = new Vector3f(Float.valueOf(line.split(" ")[1].split("/")[1]), Float.valueOf(line.split(" ")[2].split("/")[1]), Float.valueOf(line.split(" ")[3].split("/")[1])); Vector3f normalIndicies = new Vector3f(Float.valueOf(line.split(" ")[1].split("/")[2]), Float.valueOf(line.split(" ")[2].split("/")[2]), Float.valueOf(line.split(" ")[3].split("/")[2])); m.faces.add(new Face(vertexIndicies,textureIndicies,normalIndicies,currentTexture.getTextureID())); }else if(line.startsWith("g ")) { if(line.length()>2) { String name = line.split(" ")[1]; currentTexture = TextureLoader.getTexture("PNG", ResourceLoader.getResourceAsStream("res/" + name + ".png")); System.out.println(currentTexture.getTextureID()); } } } reader.close(); System.out.println(m.verticies.size() + " verticies"); System.out.println(m.normals.size() + " normals"); System.out.println(m.texVerticies.size() + " texture coordinates"); System.out.println(m.faces.size() + " faces"); return m; } } Then I create a display list for my model using this code: objectDisplayList = GL11.glGenLists(1); GL11.glNewList(objectDisplayList, GL11.GL_COMPILE); Model m = null; try { m = OBJLoader.loadModel(new File("res/untitled4.obj")); } catch (Exception e1) { e1.printStackTrace(); } int currentTexture=0; for(Face face: m.faces) { if(face.texture!=currentTexture) { currentTexture = face.texture; GL11.glBindTexture(GL11.GL_TEXTURE_2D, currentTexture); } GL11.glColor3f(1f, 1f, 1f); GL11.glBegin(GL11.GL_TRIANGLES); Vector3f n1 = m.normals.get((int) face.normal.x - 1); GL11.glNormal3f(n1.x, n1.y, n1.z); Vector2f t1 = m.texVerticies.get((int) face.textures.x -1); GL11.glTexCoord2f(t1.x, t1.y); Vector3f v1 = m.verticies.get((int) face.vertex.x - 1); GL11.glVertex3f(v1.x, v1.y, v1.z); Vector3f n2 = m.normals.get((int) face.normal.y - 1); GL11.glNormal3f(n2.x, n2.y, n2.z); Vector2f t2 = m.texVerticies.get((int) face.textures.y -1); GL11.glTexCoord2f(t2.x, t2.y); Vector3f v2 = m.verticies.get((int) face.vertex.y - 1); GL11.glVertex3f(v2.x, v2.y, v2.z); Vector3f n3 = m.normals.get((int) face.normal.z - 1); GL11.glNormal3f(n3.x, n3.y, n3.z); Vector2f t3 = m.texVerticies.get((int) face.textures.z -1); GL11.glTexCoord2f(t3.x, t3.y); Vector3f v3 = m.verticies.get((int) face.vertex.z - 1); GL11.glVertex3f(v3.x, v3.y, v3.z); GL11.glEnd(); } GL11.glEndList(); The currentTexture is an int - it contains the ID of the currently used texture. So my model looks absolutely fine without textures: (sorry I cannot post hyperlinks since I am a new user) i.imgur.com/VtoK0.png But look what happens if I enable GL_TEXTURE_2D: i.imgur.com/z8Kli.png i.imgur.com/5e9nn.png i.imgur.com/FAHM9.png As you can see an entire side of the tree appears to be missing - and it's not transparent, since it's not in the colour of the background - it's rendered black. It's not a problem with the model - if I load it using Kanji's OBJ loader it works fine(but the thing is,that I need to write my own OBJ loader) i.imgur.com/YDATo.png this is my OpenGL init section: //init display try { Display.setDisplayMode(new DisplayMode(Support.SCREEN_WIDTH, Support.SCREEN_HEIGHT)); Display.create(); Display.setVSyncEnabled(true); } catch (LWJGLException e) { e.printStackTrace(); System.exit(0); } GL11.glLoadIdentity(); GL11.glEnable(GL11.GL_TEXTURE_2D); GL11.glClearColor(1.0f, 0.0f, 0.0f, 1.0f); GL11.glShadeModel(GL11.GL_SMOOTH); GL11.glEnable(GL11.GL_DEPTH_TEST); GL11.glDepthFunc(GL11.GL_LESS); GL11.glDepthMask(true); GL11.glEnable(GL11.GL_NORMALIZE); GL11.glMatrixMode(GL11.GL_PROJECTION); GLU.gluPerspective (90.0f,800f/600f, 1f, 500.0f); GL11.glMatrixMode(GL11.GL_MODELVIEW); GL11.glEnable(GL11.GL_CULL_FACE); GL11.glCullFace(GL11.GL_BACK); //enable lighting GL11.glEnable(GL11.GL_LIGHTING); ByteBuffer temp = ByteBuffer.allocateDirect(16); temp.order(ByteOrder.nativeOrder()); GL11.glMaterial(GL11.GL_FRONT, GL11.GL_DIFFUSE, (FloatBuffer)temp.asFloatBuffer().put(lightDiffuse).flip()); GL11.glMaterialf(GL11.GL_FRONT, GL11.GL_SHININESS,(int)material_shinyness); GL11.glLight(GL11.GL_LIGHT2, GL11.GL_DIFFUSE, (FloatBuffer)temp.asFloatBuffer().put(lightDiffuse2).flip()); // Setup The Diffuse Light GL11.glLight(GL11.GL_LIGHT2, GL11.GL_POSITION,(FloatBuffer)temp.asFloatBuffer().put(lightPosition2).flip()); GL11.glLight(GL11.GL_LIGHT2, GL11.GL_AMBIENT,(FloatBuffer)temp.asFloatBuffer().put(lightAmbient).flip()); GL11.glLight(GL11.GL_LIGHT2, GL11.GL_SPECULAR,(FloatBuffer)temp.asFloatBuffer().put(lightDiffuse2).flip()); GL11.glLightf(GL11.GL_LIGHT2, GL11.GL_CONSTANT_ATTENUATION, 0.1f); GL11.glLightf(GL11.GL_LIGHT2, GL11.GL_LINEAR_ATTENUATION, 0.0f); GL11.glLightf(GL11.GL_LIGHT2, GL11.GL_QUADRATIC_ATTENUATION, 0.0f); GL11.glEnable(GL11.GL_LIGHT2); Could somebody please help me?

• Asset Pipeline acting up

  - by Abram

  Ok, so my asset pipeline has suddenly started acting up on my development machine. JS functions that previously worked are now throwing "not a function" errors.. I know I must be doing something wrong. A minute ago the datatables jquery function was working, then it was throwing an error, then it was working, and now it's not working or throwing an error. Here is my application.js //= require jquery //= require jquery-ui //= require jquery_ujs //= require_self //= require_tree . //= require dataTables/jquery.dataTables //= require dataTables/jquery.dataTables.bootstrap //= require bootstrap //= require bootstrap-tooltip //= require bootstrap-popover //= require bootstrap-tab //= require bootstrap-modal //= require bootstrap-alert //= require bootstrap-dropdown //= require jquery.ui.addresspicker //= require raty //= require jquery.alphanumeric //= require jquery.formrestrict //= require select2 //= require chosen/chosen.jquery //= require highcharts //= require jquery.lazyload Here is some of my layout header: <%= stylesheet_link_tag "application", media: "all" %> <%= yield(:scripthead) %> <%= javascript_include_tag "application" %> <%= csrf_meta_tags %> <%= yield(:head) %> Above I am using the yield to load up online scripts from google as they're only needed on some pages, and generally slow down the site if included in the application layout. I tried removing the yield but things were still broken, even after clearing the browser cache and running rake assets:clean (just to be on the safe side). Here's what shows up between CSS and metatags (for a page with nothin in the yield scripthead): <script src="/assets/jquery.js?body=1" type="text/javascript"></script> <script src="/assets/jquery-ui.js?body=1" type="text/javascript"></script> <script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script> <script src="/assets/application.js?body=1" type="text/javascript"></script> <script src="/assets/aidmodels.js?body=1" type="text/javascript"></script> <script src="/assets/audio.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-alert.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-dropdown.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-modal.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-popover.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-tab.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-tooltip.js?body=1" type="text/javascript"></script> <script src="/assets/branches.js?body=1" type="text/javascript"></script> <script src="/assets/charts.js?body=1" type="text/javascript"></script> <script src="/assets/chosen/backup_chosen.jquery.js?body=1" type="text/javascript"></script> <script src="/assets/chosen/chosen.jquery.js?body=1" type="text/javascript"></script> <script src="/assets/consumers.js?body=1" type="text/javascript"></script> <script src="/assets/dispensers.js?body=1" type="text/javascript"></script> <script src="/assets/favorites.js?body=1" type="text/javascript"></script> <script src="/assets/features.js?body=1" type="text/javascript"></script> <script src="/assets/generic_styles.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.base.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.bing.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.googlemaps.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.mapquest.js?body=1" type="text/javascript"></script> <script src="/assets/gmaps4rails/gmaps4rails.openlayers.js?body=1" type="text/javascript"></script> <script src="/assets/highcharts.js?body=1" type="text/javascript"></script> <script src="/assets/jquery-ui-1.8.18.custom.min.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.alphanumeric.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.formrestrict.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.lazyload.js?body=1" type="text/javascript"></script> <script src="/assets/jquery.ui.addresspicker.js?body=1" type="text/javascript"></script> <script src="/assets/likes.js?body=1" type="text/javascript"></script> <script src="/assets/messages.js?body=1" type="text/javascript"></script> <script src="/assets/overalls.js?body=1" type="text/javascript"></script> <script src="/assets/pages.js?body=1" type="text/javascript"></script> <script src="/assets/questions.js?body=1" type="text/javascript"></script> <script src="/assets/raty.js?body=1" type="text/javascript"></script> <script src="/assets/reviews.js?body=1" type="text/javascript"></script> <script src="/assets/sessions.js?body=1" type="text/javascript"></script> <script src="/assets/styles.js?body=1" type="text/javascript"></script> <script src="/assets/tickets.js?body=1" type="text/javascript"></script> <script src="/assets/universities.js?body=1" type="text/javascript"></script> <script src="/assets/users.js?body=1" type="text/javascript"></script> <script src="/assets/dataTables/jquery.dataTables.js?body=1" type="text/javascript"></script> <script src="/assets/dataTables/jquery.dataTables.bootstrap.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-transition.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-affix.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-button.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-carousel.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-collapse.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-scrollspy.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap-typeahead.js?body=1" type="text/javascript"></script> <script src="/assets/bootstrap.js?body=1" type="text/javascript"></script> <script src="/assets/select2.js?body=1" type="text/javascript"></script> From application.rb: config.assets.initialize_on_precompile = false # Enable the asset pipeline config.assets.enabled = true config.action_controller.assets_dir = "#{File.dirname(File.dirname(__FILE__))}/public" # Version of your assets, change this if you want to expire all your assets config.assets.version = '1.0' I'm sorry, I'm not sure what else to include to help with this puzzle, but any advise would be appreciated.

• Contact Form + jQuery validationengine

  - by BigMad

  I created this contact form, inserting jQuery fadeLabel and validationEngine to beautify the form the file index.php / .html (I have not yet figured out which of the two versions put it) scripts are index: <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <script src="/js/backtop.js"></script> <script src="/js/fadeLabel.js"></script> <script> $(document).ready(function () { $('form .fadeLabel').fadeLabel(); }); </script> <script src="/js/validationEngine-it.js"></script> <script src="/js/validationEngine.js"></script> <script> $(document).ready(function(){ $("#form_box").validationEngine({ ajaxSubmit: true, ajaxSubmitFile: "contact.php", ajaxSubmitMessage: "Thank you, We will contact you soon !", success : false, failure : function() {} }) }); </script> <script src="/js/contactform.js"></script> however this is the part of the form's code <p id="form_success" class="success hide"><strong>Grazie!</strong> Il tuo messaggio è stato inviato con successo.</p> <form id="form_box"> <fieldset> <p><label for="name">Nome*</label><input type="text" id="name" name="name" class="validate[required] fadeLabel" value=""/></p> <p><label for="email">E-mail*</label><input type="email" id="email" name="email" class="validate[required,custom[email]] fadeLabel" value=""/></p> <p><label for="website">Sito web</label><input type="url" id="website" name="website" class="fadeLabel" value=""/></p> <p><label for="message">Messaggio*</label><textarea id="message" name="message" class="validate[required] fadeLabel" cols="30" rows="10" value=""></textarea></p> </fieldset> <p id="form_submit" class="submit"><button class="send">Invia</button> *Campi obbligatori</p> <p id="form_send" class="send hide">Invio in corso&hellip;</p> <p id="form_error" class="submit error hide"><button class="send">Invia</button> Si prega di correggere l'errore e re-inviarlo.</p> </form> This is the contact.php where it receives the data and sends 2 emails (one for me with the data and a thank you to those who contacted me) contact.php: <?php //include variables $my_email = "[email protected]"; $my_site = "adrianogenovese.com"; session_start(); $name = $_POST['name']; $email = $_POST['email']; $website = $_POST['website']; $message = $_POST['message']; $ip = $_SERVER['REMOTE_ADDR']; //beginning to email me $to = $my_email; $sbj = "Richiesta Informazioni - $my_site"; $msg = " <html> ... //the body of the email to me ... </html> "; $from = $email; $headers = 'MIME-Version: 1.0' .

SlideUp (). FadeOut () so that the sending of this email appears for 3 seconds "$ (" # form_send "). addClass ('hide')" before you do anything else then the form disappears up using some second type slideUp "$ (" # form_box "). addClass ('hide')" by displaying just the "$ (" # form_success "). removeClass ('hide')" in the address bar also appears the form data (e.g. ../index.php?name=test&email=example%40mail.com&website=&message=helloworld)

• Class member functions instantiated by traits [policies, actually]

  - by Jive Dadson

  I am reluctant to say I can't figure this out, but I can't figure this out. I've googled and searched Stack Overflow, and come up empty. The abstract, and possibly overly vague form of the question is, how can I use the traits-pattern to instantiate member functions? [Update: I used the wrong term here. It should be "policies" rather than "traits." Traits describe existing classes. Policies prescribe synthetic classes.] The question came up while modernizing a set of multivariate function optimizers that I wrote more than 10 years ago. The optimizers all operate by selecting a straight-line path through the parameter space away from the current best point (the "update"), then finding a better point on that line (the "line search"), then testing for the "done" condition, and if not done, iterating. There are different methods for doing the update, the line-search, and conceivably for the done test, and other things. Mix and match. Different update formulae require different state-variable data. For example, the LMQN update requires a vector, and the BFGS update requires a matrix. If evaluating gradients is cheap, the line-search should do so. If not, it should use function evaluations only. Some methods require more accurate line-searches than others. Those are just some examples. The original version instantiates several of the combinations by means of virtual functions. Some traits are selected by setting mode bits that are tested at runtime. Yuck. It would be trivial to define the traits with #define's and the member functions with #ifdef's and macros. But that's so twenty years ago. It bugs me that I cannot figure out a whiz-bang modern way. If there were only one trait that varied, I could use the curiously recurring template pattern. But I see no way to extend that to arbitrary combinations of traits. I tried doing it using boost::enable_if, etc.. The specialized state information was easy. I managed to get the functions done, but only by resorting to non-friend external functions that have the this-pointer as a parameter. I never even figured out how to make the functions friends, much less member functions. The compiler (VC++ 2008) always complained that things didn't match. I would yell, "SFINAE, you moron!" but the moron is probably me. Perhaps tag-dispatch is the key. I haven't gotten very deeply into that. Surely it's possible, right? If so, what is best practice? UPDATE: Here's another try at explaining it. I want the user to be able to fill out an order (manifest) for a custom optimizer, something like ordering off of a Chinese menu - one from column A, one from column B, etc.. Waiter, from column A (updaters), I'll have the BFGS update with Cholesky-decompositon sauce. From column B (line-searchers), I'll have the cubic interpolation line-search with an eta of 0.4 and a rho of 1e-4, please. Etc... UPDATE: Okay, okay. Here's the playing-around that I've done. I offer it reluctantly, because I suspect it's a completely wrong-headed approach. It runs okay under vc++ 2008. #include <boost/utility.hpp> #include <boost/type_traits/integral_constant.hpp> namespace dj { struct CBFGS { void bar() {printf("CBFGS::bar %d\n", data);} CBFGS(): data(1234){} int data; }; template<class T> struct is_CBFGS: boost::false_type{}; template<> struct is_CBFGS<CBFGS>: boost::true_type{}; struct LMQN {LMQN(): data(54.321){} void bar() {printf("LMQN::bar %lf\n", data);} double data; }; template<class T> struct is_LMQN: boost::false_type{}; template<> struct is_LMQN<LMQN> : boost::true_type{}; // "Order form" struct default_optimizer_traits { typedef CBFGS update_type; // Selection from column A - updaters }; template<class traits> class Optimizer; template<class traits> void foo(typename boost::enable_if<is_LMQN<typename traits::update_type>, Optimizer<traits> >::type& self) { printf(" LMQN %lf\n", self.data); } template<class traits> void foo(typename boost::enable_if<is_CBFGS<typename traits::update_type>, Optimizer<traits> >::type& self) { printf("CBFGS %d\n", self.data); } template<class traits = default_optimizer_traits> class Optimizer{ friend typename traits::update_type; //friend void dj::foo<traits>(typename Optimizer<traits> & self); // How? public: //void foo(void); // How??? void foo() { dj::foo<traits>(*this); } void bar() { data.bar(); } //protected: // How? typedef typename traits::update_type update_type; update_type data; }; } // namespace dj int main() { dj::Optimizer<> opt; opt.foo(); opt.bar(); std::getchar(); return 0; }

• Why won't jqGrid won't populate initially in Chrome

  Hi, I've got a web page with a jqGrid that uses am xmlreader to populate itself with data that is spat out by a RoR service. The page loads fine in firefox and safari. In Chrome however I get a blank grid.

• How to simulate browser form POST method using PHP/cURL

  - by user283266

  I'm trying to simulate browser with POST method using PHP/cURL. When I looked at that live Http header it shows Content-Type: multipart/form-data. I checked on the internet where it was suggested that cURL will send multipart/form-data when a custom headers is specified to Content-Type: multipart/form-data. $headers = array( 'Content-Type' => 'multipart/form-data; boundary='.$boundary ); This didn't work for me either when I print_r(curl_getinfo()) it showed [content_type] => text/html; charset=UTF-8 Which means cURL sent a default headers I also read that sending/uploading a file with cURL will cause data to be send as multipart/form-data. I created a file which curl uploaded but again when I ran curl_getinfo I got [content_type] => text/html; charset=UTF-8 $data_array = array("field" => "@c:\file_location.txt"); I also tried to read a file content so that the only thing sent would be content NOT ATTACHED FILE but this didn't work for me curl_getinfo shows [content_type] => text/html; charset=UTF-8. $data_array = array("field" => "<c:\file_location.txt"); // note @ replaced with < Do I miss somthing here?

• Wired component null in seam EntityHome action

  - by rangalo

  I have a custom EntityHome class. I wire the dependent entity in the wire method, but when I call the action (persist) the wired component is always null. What could be the reason, similar code generated by seam gen is apparently working. Here is the entity class. I have overrden persist method to log the value of the wired element. @Name("roundHome") @Scope(ScopeType.CONVERSATION) public class RoundHome extends EntityHome<Round>{ @In(required = false) private Golfer currentGolfer; @In(create = true) private TeeSetHome teeSetHome; @Override public String persist() { logger.info("Persist called"); if (null != getInstance().getTeeSet() ) { logger.info("teeSet not null in persist"); } else { logger.info("teeSet null in persist"); // wire(); } String retVal = super.persist(); //To change body of overridden methods use File | Settings | File Templates. return retVal; } @Logger private Log logger; public void wire() { logger.info("wire called"); TeeSet teeSet = teeSetHome.getDefinedInstance(); if (null != teeSet) { getInstance().setTeeSet(teeSet); logger.info("Successfully wired the teeSet instance with color: " + teeSet.getColor()); } } public boolean isWired() { logger.info("is wired called"); if(null == getInstance().getTeeSet()) { logger.info("wired teeSet instance is null, the button will be disabled !"); return false; } else { logger.info("wired teeSet instance is NOT null, the button will be enabled !"); logger.info("teeSet color: "+getInstance().getTeeSet().getColor()); return true; } } @RequestParameter public void setRoundId(Long id) { super.setId(id); } @Override protected Round createInstance() { Round round = super.createInstance(); round.setGolfer(currentGolfer); round.setDate(new java.sql.Date(System.currentTimeMillis())); return round; } } Here the xhtml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:s="http://jboss.com/products/seam/taglib" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:a="http://richfaces.org/a4j" xmlns:rich="http://richfaces.org/rich" template="layout/template.xhtml"> <ui:define name="body"> <h:form id="roundform"> <rich:panel> <f:facet name="header>"> #{roundHome.managed ?
