• Creating a tiled map with blender

  - by JamesB

  I'm looking at creating map tiles based on a 3D model made in blender, The map is 16 x 16 in blender. I've got 4 different zoom levels and each tile is 100 x 100 pixels. The entire map at the most zoomed out level is 4 x 4 tiles constructing an image of 400 x 400. The most zoomed in level is 256 x 256 obviously constructing an image of 25600 x 25600 What I need is a script for blender that can create the tiles from the model. I've never written in python before so I've been trying to adapt a couple of the scripts which are already there. So far I've come up with a script, but it doesn't work very well. I'm having real difficulties getting the tiles to line up seamlessly. I'm not too concerned about changing the height of the camera as I can always create the same zoomed out tiles at 6400 x 6400 images and split the resulting images into the correct tiles. Here is what I've got so far... #!BPY """ Name: 'Export Map Tiles' Blender: '242' Group: 'Export' Tip: 'Export to Map' """ import Blender from Blender import Scene,sys from Blender.Scene import Render def init(): thumbsize = 200 CameraHeight = 4.4 YStart = -8 YMove = 4 XStart = -8 XMove = 4 ZoomLevel = 1 Path = "/Images/Map/" Blender.drawmap = [thumbsize,CameraHeight,YStart,YMove,XStart,XMove,ZoomLevel,Path] def show_prefs(): buttonthumbsize = Blender.Draw.Create(Blender.drawmap[0]); buttonCameraHeight = Blender.Draw.Create(Blender.drawmap[1]) buttonYStart = Blender.Draw.Create(Blender.drawmap[2]) buttonYMove = Blender.Draw.Create(Blender.drawmap[3]) buttonXStart = Blender.Draw.Create(Blender.drawmap[4]) buttonXMove = Blender.Draw.Create(Blender.drawmap[5]) buttonZoomLevel = Blender.Draw.Create(Blender.drawmap[6]) buttonPath = Blender.Draw.Create(Blender.drawmap[7]) block = [] block.append(("Image Size", buttonthumbsize, 0, 500)) block.append(("Camera Height", buttonCameraHeight, -0, 10)) block.append(("Y Start", buttonYStart, -10, 10)) block.append(("Y Move", buttonYMove, 0, 5)) block.append(("X Start", buttonXStart,-10, 10)) block.append(("X Move", buttonXMove, 0, 5)) block.append(("Zoom Level", buttonZoomLevel, 1, 10)) block.append(("Export Path", buttonPath,0,200,"The Path to save the tiles")) retval = Blender.Draw.PupBlock("Draw Map: Preferences" , block) if retval: Blender.drawmap[0] = buttonthumbsize.val Blender.drawmap[1] = buttonCameraHeight.val Blender.drawmap[2] = buttonYStart.val Blender.drawmap[3] = buttonYMove.val Blender.drawmap[4] = buttonXStart.val Blender.drawmap[5] = buttonXMove.val Blender.drawmap[6] = buttonZoomLevel.val Blender.drawmap[7] = buttonPath.val Export() def Export(): scn = Scene.GetCurrent() context = scn.getRenderingContext() def cutStr(str): #cut off path leaving name c = str.find("\\") while c != -1: c = c + 1 str = str[c:] c = str.find("\\") str = str[:-6] return str #variables from gui: thumbsize,CameraHeight,YStart,YMove,XStart,XMove,ZoomLevel,Path = Blender.drawmap XMove = XMove / ZoomLevel YMove = YMove / ZoomLevel Camera = Scene.GetCurrent().getCurrentCamera() Camera.LocZ = CameraHeight / ZoomLevel YStart = YStart + (YMove / 2) XStart = XStart + (XMove / 2) #Point it straight down Camera.RotX = 0 Camera.RotY = 0 Camera.RotZ = 0 TileCount = 4**ZoomLevel #Because the first thing we do is move the camera, start it off the map Camera.LocY = YStart - YMove for i in range(0,TileCount): Camera.LocY = Camera.LocY + YMove Camera.LocX = XStart - XMove for j in range(0,TileCount): Camera.LocX = Camera.LocX + XMove Render.EnableDispWin() context.extensions = True context.renderPath = Path #setting thumbsize context.imageSizeX(thumbsize) context.imageSizeY(thumbsize) #could be put into a gui. context.imageType = Render.PNG context.enableOversampling(0) #render context.render() #save image ZasString = '%s' %(int(ZoomLevel)) XasString = '%s' %(int(j+1)) YasString = '%s' %(int((3-i)+1)) context.saveRenderedImage("Z" + ZasString + "X" + XasString + "Y" + YasString) #close the windows Render.CloseRenderWindow() try: type(Blender.drawmap) except: #print 'initialize extern variables' init() show_prefs()

• Google map "zoomend" event issue

  - by ebae

  On my html page, I have a google map with a few markers. I want all the markers to be cleared once the zoom is changed on the map with the following code. GEvent.addListener(map, "zoomend", function() { map.clearOverlays(); } But what happens is actually the markers are removed by the "clearOverlays()" function, but then they appear again. Any idea why? Where is it going after the event is handled?

• Running Modern UI/Metro Apps as Administrator in Windows 8

  - by Shail

  I noticed that on Windows 8's Start screen, I could right click a Windows legacy program (A program which runs on Windows XP, Vista and 7), and I could run it as Administrator. However, whenever I clicked on a Windows 8 Modern UI or a Metro app, I didn't have that option. So here are my questions:- Why can't I run the Modern UI apps as an Administrator? Does it make any difference as far as security is concerned?

• AngularJS: How to make angular load script inside ng-include?

  - by Ranjith R

  Hey I am building a web page with angular. The problem is that there are somethings already build without angular and I have to include them as well The problem is this. I have something like this in my main.html: <ngInclude src="partial.html"> </ngInclude> And my partial.html has something like this <h2> heading 1 <h2> <script type="text/javascript" src="static/js/partial.js"> </script> And my partial.js has nothing to do with angularjs. nginclude works and I can see the html, but I can not see the javascript file being loaded at all. I know how to use firebug/ chrome-dev-tool, but I can not even see the network request being made. What am I doing wrong? I knwo angular has some special meaning to script tag. Can I override it?

• 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.

• How to change Jquery UI Slider handle

  - by Tom

  I want to modify the stock JQuery UI slider so that the handle has a arrow on it rather than being a square. i.e. I want to use a custom image as the handle. There are a few tutorials that do it: http://jqueryfordesigners.com/slider-gallery/ http://www.ryancoughlin.com/2008/11/04/using-the-jquery-ui-slider/ http://www.keepthewebweird.com/creating-a-nice-slider-with-jquery-ui/ But I can't get it to work. The following code results in a stationary handle image: <!DOCTYPE html> <html> <head> <link type="text/css" href="http://jqueryui.com/latest/themes/base/ui.all.css" rel="stylesheet" /> <script type="text/javascript" src="http://jqueryui.com/latest/jquery-1.3.2.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.core.js"></script> <script type="text/javascript" src="http://jqueryui.com/latest/ui/ui.slider.js"></script> <style type="text/css"> #myhandle {position: absolute;z-index: 100;height: 25px;width: 35px;top: auto;background: url(http://stackoverflow.com/content/img/so/vote-arrow-down.png) no-repeat;} </style> <script type="text/javascript"> $(document).ready(function(){ $("#slider").slider({handle: '#myhandle'}); }); </script> </head> <body> <div id="slider"><div id="myhandle"></div></div> </body> </html> It is as if JQuery doesn't pick up that I want to use the myhandle id for the handle. I'm wondering: Do I need a plugin for JQuery to recognise the handle option? (it is not documented in http://docs.jquery.com/UI/Slider). Or perhaps it only worked in an old version of JQuery? Any ideas?

  I am following the tut here http://msdn.microsoft.com/en-us/library/h59db326.aspx # Create an App_Code directory directly under the root directory of your Web site (also called Web application root). # Copy the source file for the control (WelcomeLabel.cs or WelcomeLabel.vb) to the App_Code directory.

• jquery ui autocomplete database

  - by user343925

  Hello, I'd like to use jQuery UI autocomplete in order to load a list from my database but I don't know wich method I should use to do so. I tried to use the "Remote datasource" method [url]http://jqueryui.com/demos/autocomplete/#remote[/url], but it obviously doesn't work. I have the following code : js: $(function() { $("#client").autocomplete({ source: "nom.php", minLength: 2, select: function(event, ui) { alert(ui); } }); }); html : <label for="client">Client</label> <input name="client" id="client" class="ui-autocomplete ui-widget-content ui-corner-all" /> php: $query = "SELECT nom from personne"; $result = mysql_query($query, $db); while($row = mysql_fetch_assoc($result)) { foreach($row as $val) $tab[] = $val; } print json_encode($tab); It does work with ["hello","test1","test2"] instead of the url but I need to load datas form database so pls tell me how I should do. thank you

• Atlas style map index for static google map

  - by Ben Holland

  Hello, I'm using a static google map, but really this problem could apply to any maps project. I want to divide a map into multiple quadrants (of say 50x50 pixels) and label the columns as A, B, C.... and the rows as 1, 2, 3... Next I plan to do something like, 1) Find the markers which are the farthest north, east, south, and west 2) Use that info to to define the bounding boxes of each row and column box 3) Classify each marker by its row and column (Example Marker 1 = [A,2]) A few requirements, I don't know the zoom level because I let Google set the zoom level appropriately for me and I would rather not use an algorithm that is dependent on a zoom level. I do however know the locations of all of the markers that are shown on the map. Here is an example of a map that I would like to classify the markers for, static map example link. I found these which look like a good start, Resource 1, Resource 2 But I think I'm still in need of some help getting started. Can anyone help write out some pseudo code or post a few more resources? I'm kind of in a rut at the moment. Thanks! Much appreciated of any help!

• Overlay image/map on MapView?

  - by CCDEV

  Okay, hope you can help med here :) I have been searching everywhere to figure this out, but haven't had any luck. I know about Annotations and how to overlay them on a map on the iPhone. But what if I have location like in the forest where there arent any roads or anything. What I am asking is, how can I overlay a custom image (map) over the Map view so that it zooms the right way like the map, in the right scale, and can I add my own annotations on top of the custom image/map? Hop I was clear enough on what I am trying to do?

• Vertical crosshair reposition on Google Map after map resize Issue

  - by joe

  I use the following function to add a crosshair to my Google Map. It works great for horizontal resizing. I can not figure out how to make it work for vertical. After resizing the map it requires the user to either zoom in or out 1 layer, upon which the crosshair snaps to center. var crosshairsSize=17; GMap2.prototype.addCrosshairs=function(){ var container=this.getContainer(); if(this.crosshairs){$(this.crosshairs).remove();} var crosshairs=document.createElement("img"); crosshairs.src='../images/crosshair2.gif'; crosshairs.style.width=crosshairsSize+'px'; crosshairs.style.height=crosshairsSize+'px'; crosshairs.style.border='0'; crosshairs.style.position='relative'; crosshairs.style.top=((parseInt(container.clientHeight)-crosshairsSize)/2)+'px'; crosshairs.style.left="0px"; // The map is centered so 0 will do crosshairs.style.zIndex='500'; container.appendChild(crosshairs); this.crosshairs=crosshairs; return crosshairs;}; I use map.checkResize(); and the map is correct, it's just the crosshair that is off. I've tried firing a javascript zoom in one level but it doesn't work like zooming in with the mouse. It's only zooming in/out with the mouse scroll wheel too... clicking and dragging the zoom slider doesn't work so somehow it's liking the mouse scroll wheel. Firing addCrosshairs(); after resize makes no difference. It places the new crosshair in old spot and still requires a mouse scroll zoom.

• How to apply CSS theme to only a specific jQuery-UI element?

  - by Thierry-Dimitri Roy

  I have a web site already build with my own CSS theme. I'm using jQuery UI "tabs" widget but no CSS from jQuery-UI. Now, I'm trying to add the "Date Picker" widget in one of my page. It would be great if I could reuse jQuery-UI default theme which is just fine. The problem is that the date picker theme is also applied to my tabs CSS. For example the "ui-widget" css properties is applied to both date picker and tabs elements. I can't seem to find a way to apply the css properties to only the date picker. I can't see a "super selector" that only applies to the date picker DIV. What would be the best way to handle this? [EDIT] The datepicker widget is really the problem. I cannot apply CSS style specific to it. Here is the starting code of the DIV that get pops up: <div style="position: absolute; top: 300.4px; left: 149px; display: block;" id="ui-datepicker-div" class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-helper-hidden-accessible"><div class="ui-datepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> As such, I cannot add a super selector. What would be great would be that the date picker widget supports CSS scope. But it does not. I'm stuck manually editing the jQuery CSS file. The Date Picker is currently being refactored. Hopefully the new code will address this issue.

• How to improve performance of map that loads new overlay images

  - by anthonysomerset

  I have inherited a website to maintain that uses a html map overlaying a real map to link specific countries to specific pages. previously it loaded the default map image, then with some javascript it would change the image src to an image with that particular country in a different colour on mouseover and reset the image source back to the original image on mouse out to make maintenance (adding new countries) easier i made the initial map a background image by utilising some CSS for the div tag, and then created new images for each country which only had that countries hightlight so that the images remain fairly small. this works great but theres one issue which is particularly noticeable on slower internet connections when you hover over a country if you dont have the image file in your browser cache or downloaded it wont load the image unless you hover over another country and then back onto the first country - i guess this is due to the image having to manually be downloaded on first hover. My question: is it possible to force the load of these extra images AFTER the page and all the other assets have finished loading so that this behaviour is all but eliminated? the html code for the MAP is as follows: <div class="gtmap"><img id="Image-Maps_6200909211657061" src="<?php echo cdnhttpsCheck();

• Changing background image on accordion change - jQuery Ui

  - by Coughlin

  I am using this code: $('.ui-accordion').bind('accordionchange', function(event, ui) { $(this).next().next().css({'background-image':'images/green-bg.jpg'}); //ui.newHeader // jQuery object, activated header //ui.oldHeader // jQuery object, previous header // ui.newContent // jQuery object, activated content // ui.oldContent // jQuery object, previous content }); To try to change the background image of the PREVIOUS header after it changes. I see that the jquery docs supply the object for oldHeader, but I am trying to change the CSS of that element. Any ideas how I would do that? So You go to the next one it goes green, then the current one is going to be red. Thanks, Ryan

• In Ruby on Rails, routes.rb, if map.something will create something_path and something_url, does map

  - by Jian Lin

  In Ruby on Rails, routes.rb, if we create a "named route" map.something ":a/:b", :controller => 'foobar' it will also create something_path and something_url which are two methods usable in the controller and in the view. Does map.connect create something like that too? Otherwise, isn't map.connect somewhat disadvantaged in this way? I checked that connect_path and connect_url both aren't created automatically.

• C++: retrieve map values and insert into second map

• How to save esri map as a image file

  - by Jin

  Hi, I am using Silverlight 3 and I am trying to take a screenshot of esri map. I was able to take a screenshot and save as a file for silverlight controls, but when I try to access Esri map image, I get "Pixel access not allowed" error. I heard this is because of different domain (I am trying to get map image on the client side, and map image is not accessible at server side in my silverlight application). So I am trying to find a function from esri so that I can save the map image as a file. does anybody know how to do this? or any other way around?

• SQL Server 2008 R2 Reporting Services - The Word is But a Stage (T-SQL Tuesday #006)

  - by smisner

  Host Michael Coles (blog|twitter) has selected LOB data as the topic for this month's T-SQL Tuesday, so I'll take this opportunity to post an overview of reporting with spatial data types. As part of my work with SQL Server 2008 R2 Reporting Services, I've been exploring the use of spatial data types in the new map data region. You can create a map using any of the following data sources: Map Gallery - a set of Shapefiles for the United States only that ships with Reporting Services ESRI Shapefile - a .shp file conforming to the Environmental Systems Research Institute, Inc. (ESRI) shapefile spatial data format SQL Server spatial data - a query that includes SQLGeography or SQLGeometry data types Rob Farley (blog|twitter) points out today in his T-SQL Tuesday post that using the SQL geography field is a preferable alternative to ESRI shapefiles for storing spatial data in SQL Server. So how do you get spatial data? If you don't already have a GIS application in-house, you can find a variety of sources. Here are a few to get you started: US Census Bureau Website, http://www.census.gov/geo/www/tiger/ Global Administrative Areas Spatial Database, http://biogeo.berkeley.edu/gadm/ Digital Chart of the World Data Server, http://www.maproom.psu.edu/dcw/ In a recent post by Pinal Dave (blog|twitter), you can find a link to free shapefiles for download and a tutorial for using Shape2SQL, a free tool to convert shapefiles into SQL Server data. In my post today, I'll show you how to use combine spatial data that describes boundaries with spatial data in AdventureWorks2008R2 that identifies stores locations to embed a map in a report. Preparing the spatial data First, I downloaded Shapefile data for the administrative boundaries in France and unzipped the data to a local folder. Then I used Shape2SQL to upload the data into a SQL Server database called Spatial. I'm not sure of the reason why, but I had to uncheck the option to create a spatial index to upload the data. Otherwise, the upload appeared to run successfully, but no table appeared in my database. The zip file that I downloaded contained three files, but I didn't know what was in them until I used Shape2SQL to upload the data into tables. Then I found that FRA_adm0 contains spatial data for the country of France, FRA_adm1 contains spatial data for each region, and FRA_adm2 contains spatial data for each department (a subdivision of region). Next I prepared my SQL query containing sales data for fictional stores selling Adventure Works products in France. The Person.Address table in the AdventureWorks2008R2 database (which you can download from Codeplex) contains a SpatialLocation column which I joined - along with several other tables - to the Sales.Customer and Sales.Store tables. I'll be able to superimpose this data on a map to see where these stores are located. I included the SQL script for this query (as well as the spatial data for France) in the downloadable project that I created for this post. Step 1: Using the Map Wizard to Create a Map of France You can build a map without using the wizard, but I find it's rather useful in this case. Whether you use Business Intelligence Development Studio (BIDS) or Report Builder 3.0, the map wizard is the same. I used BIDS so that I could create a project that includes all the files related to this post. To get started, I added an empty report template to the project and named it France Stores. Then I opened the Toolbox window and dragged the Map item to the report body which starts the wizard. Here are the steps to perform to create a map of France: On the Choose a source of spatial data page of the wizard, select SQL Server spatial query, and click Next. On the Choose a dataset with SQL Server spatial data page, select Add a new dataset with SQL Server spatial data. On the Choose a connection to a SQL Server spatial data source page, select New. In the Data Source Properties dialog box, on the General page, add a connecton string like this (changing your server name if necessary): Data Source=(local);Initial Catalog=Spatial Click OK and then click Next. On the Design a query page, add a query for the country shape, like this: select * from fra_adm1 Click Next. The map wizard reads the spatial data and renders it for you on the Choose spatial data and map view options page, as shown below. You have the option to add a Bing Maps layer which shows surrounding countries. Depending on the type of Bing Maps layer that you choose to add (from Road, Aerial, or Hybrid) and the zoom percentage you select, you can view city names and roads and various boundaries. To keep from cluttering my map, I'm going to omit the Bing Maps layer in this example, but I do recommend that you experiment with this feature. It's a nice integration feature. Use the + or - button to rexize the map as needed. (I used the + button to increase the size of the map until its edges were just inside the boundaries of the visible map area (which is called the viewport). You can eliminate the color scale and distance scale boxes that appear in the map area later. Select the Embed map data in this report for faster rendering. The spatial data won't be changing, so there's no need to leave it in the database. However, it does increase the size of the RDL. Click Next. On the Choose map visualization page, select Basic Map. We'll add data for visualization later. For now, we have just the outline of France to serve as the foundation layer for our map. Click Next, and then click Finish. Now click the color scale box in the lower left corner of the map, and press the Delete key to remove it. Then repeat to remove the distance scale box in the lower right corner of the map. Step 2: Add a Map Layer to an Existing Map The map data region allows you to add multiple layers. Each layer is associated with a different data set. Thus far, we have the spatial data that defines the regional boundaries in the first map layer. Now I'll add in another layer for the store locations by following these steps: If the Map Layers windows is not visible, click the report body, and then click twice anywhere on the map data region to display it. Click on the New Layer Wizard button in the Map layers window. And then we start over again with the process by choosing a spatial data source. Select SQL Server spatial query, and click Next. Select Add a new dataset with SQL Server spatial data, and click Next. Click New, add a connection string to the AdventureWorks2008R2 database, and click Next. Add a query with spatial data (like the one I included in the downloadable project), and click Next. The location data now appears as another layer on top of the regional map created earlier. Use the + button to resize the map again to fill as much of the viewport as possible without cutting off edges of the map. You might need to drag the map within the viewport to center it properly. Select Embed map data in this report, and click Next. On the Choose map visualization page, select Basic Marker Map, and click Next. On the Choose color theme and data visualization page, in the Marker drop-down list, change the marker to diamond. There's no particular reason for a diamond; I think it stands out a little better than a circle on this map. Clear the Single color map checkbox as another way to distinguish the markers from the map. You can of course create an analytical map instead, which would change the size and/or color of the markers according to criteria that you specify, such as sales volume of each store, but I'll save that exploration for another post on another day. Click Finish and then click Preview to see the rendered report. Et voilà...c'est fini. Yes, it's a very simple map at this point, but there are many other things you can do to enhance the map. I'll create a series of posts to explore the possibilities. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Developing with Fluid UI – The Fluid Home Page

  - by Dave Bain

  v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} The first place to start with Fluid UI is with the Fluid Home Page. Sometimes it’s referred to as the landing page, but it’s formally called the Fluid Home Page. It’s delivered with PeopleTools 8.54, and the nice thing about it is, it’s a component. That’s one thing you’ll discover with Fluid UI. Fluid UI is built int PeopleTools with Fluid UI. The Home Page is a component, the tiles or grouplets are group boxes, and the search and prompt pages are just pages. It makes it easy to find things, customize and brand the applications (and of course to see what’s going on) when you can open it in AppDesigner. To see what makes a component fluid, let’s start with the Fluid Home Page. It’s a component called PT_LANDINGPAGE. You can open it in AppDesigner and see what’s unique and different about Fluid UI. If you open the Component Properties dialog, you’ll see a new tab called Fluid On the Component Properties Fluid tab you’ll see the most important checkbox of all, Fluid Mode. That is the one flag that will tell PeopleSoft if the component is Fluid (responsive, dynamic layout) or classic (pixel perfect). Now that you know it’s a single flag, you know that a component can’t be both Fluid UI and Classic at the same time, it’s one or the other. There are some other interesting fields on this page. The Small Form Factor Optimized field tells us whether or not to display this on a small device (think smarphone). Header Toolbar Actions offer standard options that are set at the component level so you have complete control of the components header bar. You’ll notice that the PT_LANDINGPAGE has got some PostBuild PeopleCode. That’s to build the grouplets that are used to launch Fluid UI Pages (more about those later). Probably not a good idea to mess with that code! The next thing to look at is the Page Definition for the PT_LANDINGPAGE component. When you open the page PT_LANDINGPAGE it will look different than anything you’ve ever seen. You’re probably thinking “What’s up with all the group boxes”? That is where Fluid UI is so different. In classic PeopleSoft, you put a button, field, group, any control on a page and that’s where it shows up, no questions asked. With Fluid UI, everything is positioned relative to something else. That’s why there are so many containers (you know them as group boxes). They are UI objects that are used for dynamic positioning. The Fluid Home Page has some special behavior and special settings. The first is in the Web Profile Configuration settings (Main Menu->PeopleTools->Web Profile->Web Profile Configuration from the main menu). There are two checkboxes that control the behavior of Fluid UI. Disable Fluid Mode and Disable Fluid On Desktop. Disable Fluid Mode prevents any Fluid UI component from being run from this installation. This is a web profile setting for users that want to run later versions of PeopleTools but only want to run Classic PeopleSoft pages. The second setting, Disable Fluid On Desktop allows the Fluid UI to be run on mobile devices such as smartphones and tablets, but prevents Fluid UI from running on a desktop computer. Fluid UI settings are also make in My Personalizations (Main Menu->My Personalizations from the Main Menu), in the General Options section. In that section, each user has the choice to determine the home page for their desktop and for tablets. Now that you know the Fluid UI landing page is just a component, and the profile and personalization settings, you should be able to launch one. It’s pretty easy to add a menu using Structure and Content, just make sure the proper security is set up. You’ll have to run a Fluid UI supported browser in order to see it. Latest versions of Chrome, Firefox and IE will do. Check the certification page on MOS for all the details. When you open the first Fluid Landing Page, there’s not much there. Not to worry, we’ll get some content on it soon. Take a moment to navigate around and look at some of the header actions that were set up from the component properties. The home button takes you back to the classic system. You won’t see any notifications and the personalization doesn’t have any content to add. The NavBar icon on the top right has a lot of content, including a Navigator and Classic home. Spend some time looking through what’s available. Stay tuned for more. Next up is adding some content.

• Map a Network Drive from XP to Windows 7

  - by Mysticgeek

  We’ve received a lot of questions about mapping a drive from XP to Windows 7 to access data easily. Today we look at how to map a drive in Windows 7, and how to map to an XP drive from Windows 7. With the new Homegroup feature in Windows 7, it makes sharing data between computers a lot easier. But you might need to map a network drive so you can go directly into a folder to access its contents. Mapping a network drive may sound like “IT talk”, but the process is fairly easy. Map Network Drive in Windows 7 Note: All of the computers used in this article are part of the same workgroup on a home network. In this first example we’re mapping to another Windows 7 drive on the network. Open Computer and from the toolbar click on Map Network Drive. Alternately in Computer you can hit “Alt+T” to pull up the toolbar and click on Tools \ Map Network Drive. Now give it an available drive letter, type in the path or browse to the folder you want to map to. Check the box next to Reconnect at logon if you want it available after a reboot, and click Finish. If both machines aren’t part of the same Homegroup, you may be prompted to enter in a username and password. Make sure and check the box next to Remember my credentials if you don’t want to log in every time to access it. The drive will map and the contents of the folder will open up. When you look in Computer, you’ll see the drive under network location. This process works if you want to connect to a server drive as well. In this example we map to a Home Server drive. Map an XP Drive to Windows 7 There might be times when you need to map a drive on an XP machine on your network. There are extra steps you’ll need to take to make it work however. Here we take a look at the problem you’ll encounter when trying to map to an XP machine if things aren’t set up correctly. If you try to browse to your XP machine you’ll see a message that you don’t have permission. Or if you try to enter in the path directly, you’ll be prompted for a username and password, and the annoyance is, no matter what credentials you put in, you can’t connect. To solve the problem we need to set up the Windows 7 machine as a user on the XP machine and make them part of the Administrators group. Right-click My Computer and select Manage. Under Computer Management expand Local Users and Groups and click on the Users folder. Right-click an empty area and click New User. Add in the user credentials, uncheck User must change password at next logon, then check Password never expires then click Create. Now you see the new user you created in the list. After the user is added you might want to reboot before proceeding to the next step.   Next we need to make the user part of the Administrators group. So go back into Computer Management \ Local Users and Groups \ Groups then double click on Administrators. Click the Add button in Administrators Properties window. Enter in the new user you created and click OK. An easy way to do this is to enter the name of the user you created then click Check Names and the path will be entered in for you. Now you see the user as a member of the Administrators group. Back on the Windows 7 machine we’ll start the process of mapping a drive. Here we’re browsing to the XP Media Center Edition machine. Now we can enter in the user name and password we just created. If you only want to access specific shared folders on the XP machine you can browse to them. Or if you want to map to the entire drive, enter in the drive path where in this example it’s “\\XPMCE\C$” –Don’t forget the “$” sign after the local drive letter. Then login… Again the contents of the drive will open up for you to access. Here you can see we have two drives mapped. One to another Windows 7 machine on the network, and the other one to the XP computer.   If you ever want to disconnect a drive, just right-click on it and then Disconnect. There are several scenarios where you might want to map a drive in Windows 7 to access specific data. It takes a little bit of work but you can map to an XP drive from Windows 7 as well. This comes in handy where you have a network with different versions of Windows running on it.
