• Spring MVC return ajax response using Jackson

  - by anshumn

  I have a scenario where I am filling a dropdown box in JSP through AJAX response from the server. In the controller, I am retuning a Collection of Product objects and have annotated the return type with @ResponseBody. Controller - @RequestMapping(value="/getServicesForMarket", method = RequestMethod.GET) public @ResponseBody Collection<Product> getServices(@RequestParam(value="marketId", required=true) int marketId) { Collection<Product> products = marketService.getProducts(marketId); return products; } And Product is @Entity @Table(name = "PRODUCT") public class Product implements Serializable { private static final long serialVersionUID = 1L; private int id; private Market market; private Service service; private int price; @Id @GeneratedValue(strategy = GenerationType.AUTO) public int getId() { return id; } public void setId(int id) { this.id = id; } @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name = "MARKET_ID") public Market getMarket() { return market; } public void setMarket(Market market) { this.market = market; } @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name = "SERVICE_ID") public Service getService() { return service; } public void setService(Service service) { this.service = service; } @Column(name = "PRICE") public int getPrice() { return price; } public void setPrice(int price) { this.price = price; } } Service is @Entity @Table(name="SERVICE") public class Service implements Serializable { /** * */ private static final long serialVersionUID = 1L; private int id; private String name; private String description; @Id @GeneratedValue @Column(name="ID") public int getId() { return id; } public void setId(int id) { this.id = id; } @Column(name="NAME") public String getName() { return name; } public void setName(String name) { this.name = name; } @Column(name="DESCRIPTION") public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } } In the JSP, I need to get the data from the service field of Product also. So I in my JQuery callback function, I have written like product.service.description to get the data. It seems that by default Jackson is not mapping the associated service object (or any other custom object). Also I am not getting any exception. In the JSP, I do not get the data. It is working fine when I return Collection of some object which does not contain any other custom objects as its fields. Am I missing any settings for this to work? Thanks!

• Django, want to upload eather image (ImageField) or file (FileField)

  - by Serg

  I have a form in my html page, that prompts user to upload File or Image to the server. I want to be able to upload ether file or image. Let's say if user choose file, image should be null, and vice verso. Right now I can only upload both of them, without error. But If I choose to upload only one of them (let's say I choose image) I will get an error: "Key 'attachment' not found in <MultiValueDict: {u'image': [<InMemoryUploadedFile: police.jpg (image/jpeg)>]}>" models.py: #Description of the file class FileDescription(models.Model): TYPE_CHOICES = ( ('homework', 'Homework'), ('class', 'Class Papers'), ('random', 'Random Papers') ) subject = models.ForeignKey('Subjects', null=True, blank=True) subject_name = models.CharField(max_length=100, unique=False) category = models.CharField(max_length=100, unique=False, blank=True, null=True) file_type = models.CharField(max_length=100, choices=TYPE_CHOICES, unique=False) file_uploaded_by = models.CharField(max_length=100, unique=False) file_name = models.CharField(max_length=100, unique=False) file_description = models.TextField(unique=False, blank=True, null=True) file_creation_time = models.DateTimeField(editable=False) file_modified_time = models.DateTimeField() attachment = models.FileField(upload_to='files', blank=True, null=True, max_length=255) image = models.ImageField(upload_to='files', blank=True, null=True, max_length=255) def __unicode__(self): return u'%s' % (self.file_name) def get_fields(self): return [(field, field.value_to_string(self)) for field in FileDescription._meta.fields] def filename(self): return os.path.basename(self.image.name) def category_update(self): category = self.file_name return category def save(self, *args, **kwargs): if self.category is None: self.category = FileDescription.category_update(self) for field in self._meta.fields: if field.name == 'image' or field.name == 'attachment': field.upload_to = 'files/%s/%s/' % (self.file_uploaded_by, self.file_type) if not self.id: self.file_creation_time = datetime.now() self.file_modified_time = datetime.now() super(FileDescription, self).save(*args, **kwargs) forms.py class ContentForm(forms.ModelForm): file_name =forms.CharField(max_length=255, widget=forms.TextInput(attrs={'size':20})) file_description = forms.CharField(widget=forms.Textarea(attrs={'rows':4, 'cols':25})) class Meta: model = FileDescription exclude = ('subject', 'subject_name', 'file_uploaded_by', 'file_creation_time', 'file_modified_time', 'vote') def clean_file_name(self): name = self.cleaned_data['file_name'] # check the length of the file name if len(name) < 2: raise forms.ValidationError('File name is too short') # check if file with same name is already exists if FileDescription.objects.filter(file_name = name).exists(): raise forms.ValidationError('File with this name already exists') else: return name views.py if request.method == "POST": if "upload-b" in request.POST: form = ContentForm(request.POST, request.FILES, instance=subject_id) if form.is_valid(): # need to add some clean functions # handle_uploaded_file(request.FILES['attachment'], # request.user.username, # request.POST['file_type']) form.save() up_f = FileDescription.objects.get_or_create( subject=subject_id, subject_name=subject_name, category = request.POST['category'], file_type=request.POST['file_type'], file_uploaded_by = username, file_name=form.cleaned_data['file_name'], file_description=request.POST['file_description'], image = request.FILES['image'], attachment = request.FILES['attachment'], ) return HttpResponseRedirect(".")

• SQLiteException and SQLite error near "(": syntax error with Subsonic ActiveRecord

  - by nvuono

  I ran into an interesting error with the following LiNQ query using LiNQPad and when using Subsonic 3.0.x w/ActiveRecord within my project and wanted to share the error and resolution for anyone else who runs into it. The linq statement below is meant to group entries in the tblSystemsValues collection into their appropriate system and then extract the system with the highest ID. from ksf in KeySafetyFunction where ksf.Unit == 2 && ksf.Condition_ID == 1 join sys in tblSystems on ksf.ID equals sys.KeySafetyFunction join xval in (from t in tblSystemsValues group t by t.tblSystems_ID into groupedT select new { sysId = groupedT.Key, MaxID = groupedT.Max(g=>g.ID), MaxText = groupedT.First(gt2 => gt2.ID == groupedT.Max(g=>g.ID)).TextValue, MaxChecked = groupedT.First(gt2 => gt2.ID == groupedT.Max(g=>g.ID)).Checked }) on sys.ID equals xval.sysId select new {KSFDesc=ksf.Description, sys.Description, xval.MaxText, xval.MaxChecked} On its own, the subquery for grouping into groupedT works perfectly and the query to match up KeySafetyFunctions with their System in tblSystems also works perfectly on its own. However, when trying to run the completed query in linqpad or within my project I kept running into a SQLiteException SQLite Error Near "(" First I tried splitting the queries up within my project because I knew that I could just run a foreach loop over the results if necessary. However, I continued to receive the same exception! I eventually separated the query into three separate parts before I realized that it was the lazy execution of the queries that was killing me. It then became clear that adding the .ToList() specifier after the myProtectedSystem query below was the key to avoiding the lazy execution after combining and optimizing the query and being able to get my results despite the problems I encountered with the SQLite driver. // determine the max Text/Checked values for each system in tblSystemsValue var myProtectedValue = from t in tblSystemsValue.All() group t by t.tblSystems_ID into groupedT select new { sysId = groupedT.Key, MaxID = groupedT.Max(g => g.ID), MaxText = groupedT.First(gt2 => gt2.ID ==groupedT.Max(g => g.ID)).TextValue, MaxChecked = groupedT.First(gt2 => gt2.ID ==groupedT.Max(g => g.ID)).Checked}; // get the system description information and filter by Unit/Condition ID var myProtectedSystem = (from ksf in KeySafetyFunction.All() where ksf.Unit == 2 && ksf.Condition_ID == 1 join sys in tblSystem.All() on ksf.ID equals sys.KeySafetyFunction select new {KSFDesc = ksf.Description, sys.Description, sys.ID}).ToList(); // finally join everything together AFTER forcing execution with .ToList() var joined = from protectedSys in myProtectedSystem join protectedVal in myProtectedValue on protectedSys.ID equals protectedVal.sysId select new {protectedSys.KSFDesc, protectedSys.Description, protectedVal.MaxChecked, protectedVal.MaxText}; // print the gratifying debug results foreach(var protectedItem in joined) { System.Diagnostics.Debug.WriteLine(protectedItem.Description + ", " + protectedItem.KSFDesc + ", " + protectedItem.MaxText + ", " + protectedItem.MaxChecked); }

• how to find maximum frequent item sets from large transactional data file

  - by ANIL MANE

  Hi, I have the input file contains large amount of transactions like Transaction ID Items T1 Bread, milk, coffee, juice T2 Juice, milk, coffee T3 Bread, juice T4 Coffee, milk T5 Bread, Milk T6 Coffee, Bread T7 Coffee, Bread, Juice T8 Bread, Milk, Juice T9 Milk, Bread, Coffee, T10 Bread T11 Milk T12 Milk, Coffee, Bread, Juice i want the occurrence of every unique item like Item Name Count Bread 9 Milk 8 Coffee 7 Juice 6 and from that i want an a fp-tree now by traversing this tree i want the maximal frequent itemsets as follows The basic idea of method is to dispose nodes in each “layer” from bottom to up. The concept of “layer” is different to the common concept of layer in a tree. Nodes in a “layer” mean the nodes correspond to the same item and be in a linked list from the “Head Table”. For nodes in a “layer” NBN method will be used to dispose the nodes from left to right along the linked list. To use NBN method, two extra fields will be added to each node in the ordered FP-Tree. The field tag of node N stores the information of whether N is maximal frequent itemset, and the field count’ stores the support count information in the nodes at left. In Figure, the first node to be disposed is “juice: 2”. If the min_sup is equal to or less than 2 then “bread, milk, coffee, juice” is a maximal frequent itemset. Firstly output juice:2 and set the field tag of “coffee:3” as “false” (the field tag of each node is “true” initially ). Next check whether the right four itemsets juice:1 be the subset of juice:2. If the itemset one node “juice:1” corresponding to is the subset of juice:2 set the field tag of the node “false”. In the following process when the field tag of the disposed node is FALSE we can omit the node after the same tagging. If the min_sup is more than 2 then check whether the right four juice:1 is the subset of juice:2. If the itemset one node “juice:1” corresponding to is the subset of juice:2 then set the field count’ of the node with the sum of the former count’ and 2 After all the nodes “juice” disposed ,begin to dispose the node “coffee:3”. Any suggestions or available source code, welcome. thanks in advance

• [NSIS] Custom radio-buttom INI page via Eclipse

  - by Omegazero

  I'm using Eclipse's create InstallOptions menu to create a custom INI page with radio-buttons for repackaging the Blackberry Desktop installer. There are 2 sections for each type: "Internet" and "Enterprise". I need a user to select 1 of the 2 options and depending on their selection, the page will carry over the selection chosen in the custom page, jump to the INSTFILES page, and continue onto the end. I couldn't find any concrete documentation on getting INI pages to load in the script (I'm probably searching incorrectly), and then pass data from one page to the next (according to fields I guess?)

• c# - How do you get a variable's name as it was physically typed in its declaration?

  - by Petras

  The class below contains the field city. I need to dynamically determine the field's name as it is typed in the class declaration i.e. I need to get the string "city" from an instance of the object city. I have tried to do this by examining its Type in DoSomething() but can't find it when examining the contents of the Type in the debugger. Is it possible? public class Person { public string city = "New York"; public Person() { } public void DoSomething() { Type t = city.GetType(); string field_name = t.SomeUnkownFunction(); //would return the string "city" if it existed! } } Some people in their answers below have asked me why I want to do this. Here's why. In my real world situation, there is a custom attribute above city. [MyCustomAttribute("param1", "param2", etc)] public string city = "New York"; I need this attribute in other code. To get the attribute, I use reflection. And in the reflection code I need to type the string "city" MyCustomAttribute attr; Type t = typeof(Person); foreach (FieldInfo field in t.GetFields()) { if (field.Name == "city") { //do stuff when we find the field that has the attribute we need } } Now this isn't type safe. If I changed the variable "city" to "workCity" in my field declaration in Person this line would fail unless I knew to update the string if (field.Name == "workCity") //I have to make this change in another file for this to still work, yuk! { } So I am trying to find some way to pass the string to this code without physically typing it. Yes, I could declare it as a string constant in Person (or something like that) but that would still be typing it twice. Phew! That was tough to explain!! Thanks Thanks to all who answered this * a lot*. It sent me on a new path to better understand lambda expressions. And it created a new question.

  I've seen similar questions posted and tried to change them to meet my needs but I don't know enough about javascript to do it. I need that when a user change the dropdown select, the "titre text field" maxlength is dynamically changed a, b c and d max maxlength should be 40 and e maxlength should be 2 my code is below, I don't know why but it is not working correctly: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>title page</title> </head> <body> <script type="text/javascript"> function changeValue(dropdown) { var option = dropdown.options[dropdown.selectedIndex].value, field = document.getElementById('titre'); if (option == 'a' || option == 'b' || option == 'c' || option == 'd') { field.maxLength = 40; } else if (option == 'e') { field.value = field.value.substr(0, 2); // before reducing the maxlength, make sure it contains at most two characters; you could also reset the value altogether field.maxLength = 2; } }? </script> <form action="converter.php" method="post"> <h2>Feel all field below:</h2> <div> Title: <input type="texte" name="titre" id="titre" maxLength="40"/> Format: <select id="format" name="format" onchange="changeValue(this);"> <option value="a">A</option> <option value="b">B</option> <option value="c">C</option> <option value="d">D</option> <option value="e">E</option> </select> </div> <div> <textarea name="texte" style="width: 415px; height: 155px;"></textarea> </div> <div> <input type="submit" value="OK" /> </div> </form> </body> </html>

• Javascript to add cdata section on the fly?

  - by Chris G.

  I'm having trouble with special characters that exist in an xml node attribute. To combat this, I'm trying to render the attributes as child nodes and, where necessary, using cdata sections to get around the special characters. The problem is, I can't seem to get the cdata section appended to the node correctly. I'm iterating over the source xml node's attributes and creating new nodes. If the attribute.name = "description" I want to put the attribute.text() in a cdata section and append the new node. That's where I jump the track. // newXMLData is the new xml document that I've created in memory for (var ctr =0;ctr< this.attributes.length;ctr++){ // iterate over the attributes if( this.attributes[ctr].name =="Description"){ // if the attribute name is "Description" add a CDATA section var thisNodeName = this.attributes[ctr].name; newXMLDataNode.append("<"+thisNodeName +"></"+ thisNodeName +">" ); var cdata = newXMLData.createCDATASection('test'); // here's where it breaks. } else { // It's not "Description" so just append the new node. newXMLDataNode.append("<"+ this.attributes[ctr].name +">" + $(this.attributes[ctr]).text() + "</"+ this.attributes[ctr].name +">" ); } } Any ideas? Is there another way to add a cdata section? Here's a sample snippet of the source... <row pSiteID="4" pSiteTile="Test Site Name " pSiteURL="http://www.cnn.com" ID="1" Description="<div>blah blah blah since June 2007.&amp;nbsp; T<br>&amp;nbsp;<br>blah blah blah blah&amp;nbsp; </div>" CreatedDate="2010-09-20 14:46:18" Comments="Comments example.&#10;" > here's what I'm trying to create... <Site> <PSITEID>4</PSITEID> <PSITETILE>Test Site Name</PSITETILE> <PSITEURL>http://www.cnn.com</PSITEURL> <ID>1</ID> <DESCRIPTION><![CDATA[<div>blah blah blah since June 2007.&amp;nbsp; T<br>&amp;nbsp;<br>blah blah blah blah&amp;nbsp; </div ]]></DESCRIPTION> <CREATEDDATE>2010-09-20 14:46:18</CREATEDDATE> <COMMENTS><![CDATA[ Comments example.&#10;]]></COMMENTS> </Site>

• Lithium: Run filter after find() to format output

  - by Housni

  I wanted to specify the output of a field from within my model so I added a date key to my $_schema: models/Tags.php <?php protected $_schema = array( 'id' => array('type' => 'integer', 'key' => 'primary'), 'title' => array('type' => 'string'), 'created' => array('type' => 'integer', 'date' => 'F jS, Y - g:i a'), 'modified' => array('type' => 'integer') ); ?> I store my time as an unsigned integer in the db (output of time()). I want my base model to format any field that has the date key for output. I thought the best place to do that would be right after a find: extensions/data/Model.php <?php static::applyFilter('find', function($self, $params, $chain) { $schema = $self::schema(); $entity = $chain->next($self, $params, $chain); foreach ($schema as $field => $options) { if (array_key_exists('date', $options)) { //format as a date $params['data'][$field] = $entity->formatDate($field, $options['date']); } } return $entity; }); public function formatdate($entity, $field, $format, $timezone = 'Asia/Colombo') { $dt = new \DateTime(); $tz = new \DateTimeZone($timezone); $dt->setTimestamp($entity->$field); $dt->setTimezone($tz); return $dt->format($format); } ?> This doesn't seem to be working. When I execute a find all, this filter seems to get hit twice. The first time, $entity contains a count() of the results and only on the second hit does it contain the Records object. What am I doing wrong? How do I alter this so that simply doing <?= $tag->created; ?> in my view will format the date the way I want? This, essentially, needs to be an 'after filter', of sorts. EDIT If I can find a way to access the current model entity object (not the full namespaced path, $self contains that), I can probably solve my problem.

• Why is my Type.GetFields(BindingFlags.Instance|BindingFlags.Public) not working?

  - by granadaCoder

• Why is my (Type).GetFields(BindingFlags.Instance | BindingFlags.Public) not working?

  - by granadaCoder

  My code can see the NonPublic members, but not the Public ones. (???) Full sample code below. FieldInfo[] publicFieldInfos = t.GetFields(BindingFlags.Instance | BindingFlags.Public); is returning nothing. Note, I'm trying to get at the properties on the abstract class as well as the 1 concrete class. (And read the attributes as well). I'm going bonkers on this one....the msdn example works with the 2 flags (BindingFlags.Instance | BindingFlags.Public).....but my mini inheritance example below is not.

• Writing Unit Tests for ASP.NET Web API Controller

  - by shiju

  In this blog post, I will write unit tests for a ASP.NET Web API controller in the EFMVC reference application. Let me introduce the EFMVC app, If you haven't heard about EFMVC. EFMVC is a simple app, developed as a reference implementation for demonstrating ASP.NET MVC, EF Code First, ASP.NET Web API, Domain-Driven Design (DDD), Test-Driven Development (DDD). The current version is built with ASP.NET MVC 4, EF Code First 5, ASP.NET Web API, Autofac, AutoMapper, Nunit and Moq. All unit tests were written with Nunit and Moq. You can download the latest version of the reference app from http://efmvc.codeplex.com/ Unit Test for HTTP Get Let’s write a unit test class for verifying the behaviour of a ASP.NET Web API controller named CategoryController. Let’s define mock implementation for Repository class, and a Command Bus that is used for executing write operations.  [TestFixture] public class CategoryApiControllerTest { private Mock<ICategoryRepository> categoryRepository; private Mock<ICommandBus> commandBus; [SetUp] public void SetUp() {     categoryRepository = new Mock<ICategoryRepository>();     commandBus = new Mock<ICommandBus>(); } The code block below provides the unit test for a HTTP Get operation. [Test] public void Get_All_Returns_AllCategory() {     // Arrange        IEnumerable<CategoryWithExpense> fakeCategories = GetCategories();     categoryRepository.Setup(x => x.GetCategoryWithExpenses()).Returns(fakeCategories);     CategoryController controller = new CategoryController(commandBus.Object, categoryRepository.Object)     {         Request = new HttpRequestMessage()                 {                     Properties = { { HttpPropertyKeys.HttpConfigurationKey, new HttpConfiguration() } }                 }     };     // Act     var categories = controller.Get();     // Assert     Assert.IsNotNull(categories, "Result is null");     Assert.IsInstanceOf(typeof(IEnumerable<CategoryWithExpense>),categories, "Wrong Model");             Assert.AreEqual(3, categories.Count(), "Got wrong number of Categories"); }        The GetCategories method is provided below: private static IEnumerable<CategoryWithExpense> GetCategories() {     IEnumerable<CategoryWithExpense> fakeCategories = new List<CategoryWithExpense> {     new CategoryWithExpense {CategoryId=1, CategoryName = "Test1", Description="Test1Desc", TotalExpenses=1000},     new CategoryWithExpense {CategoryId=2, CategoryName = "Test2", Description="Test2Desc",TotalExpenses=2000},     new CategoryWithExpense { CategoryId=3, CategoryName = "Test3", Description="Test3Desc",TotalExpenses=3000}       }.AsEnumerable();     return fakeCategories; } In the unit test method Get_All_Returns_AllCategory, we specify setup on the mocked type ICategoryrepository, for a call to GetCategoryWithExpenses method returns dummy data. We create an instance of the ApiController, where we have specified the Request property of the ApiController since the Request property is used to create a new HttpResponseMessage that will provide the appropriate HTTP status code along with response content data. Unit Tests are using for specifying the behaviour of components so that we have specified that Get operation will use the model type IEnumerable<CategoryWithExpense> for sending the Content data. The implementation of HTTP Get in the CategoryController is provided below: public IQueryable<CategoryWithExpense> Get() {     var categories = categoryRepository.GetCategoryWithExpenses().AsQueryable();     return categories; } Unit Test for HTTP Post The following are the behaviours we are going to implement for the HTTP Post: A successful HTTP Post  operation should return HTTP status code Created An empty Category should return HTTP status code BadRequest A successful HTTP Post operation should provide correct Location header information in the response for the newly created resource. Writing unit test for HTTP Post is required more information than we write for HTTP Get. In the HTTP Post implementation, we will call to Url.Link for specifying the header Location of Response as shown in below code block. var response = Request.CreateResponse(HttpStatusCode.Created, category); string uri = Url.Link("DefaultApi", new { id = category.CategoryId }); response.Headers.Location = new Uri(uri); return response; While we are executing Url.Link from unit tests, we have to specify HttpRouteData information from the unit test method. Otherwise, Url.Link will get a null value. The code block below shows the unit tests for specifying the behaviours for the HTTP Post operation. [Test] public void Post_Category_Returns_CreatedStatusCode() {     // Arrange        commandBus.Setup(c => c.Submit(It.IsAny<CreateOrUpdateCategoryCommand>())).Returns(new CommandResult(true));     Mapper.CreateMap<CategoryFormModel, CreateOrUpdateCategoryCommand>();          var httpConfiguration = new HttpConfiguration();     WebApiConfig.Register(httpConfiguration);     var httpRouteData = new HttpRouteData(httpConfiguration.Routes["DefaultApi"],         new HttpRouteValueDictionary { { "controller", "category" } });     var controller = new CategoryController(commandBus.Object, categoryRepository.Object)     {         Request = new HttpRequestMessage(HttpMethod.Post, "http://localhost/api/category/")         {             Properties =             {                 { HttpPropertyKeys.HttpConfigurationKey, httpConfiguration },                 { HttpPropertyKeys.HttpRouteDataKey, httpRouteData }             }         }     };     // Act     CategoryModel category = new CategoryModel();     category.CategoryId = 1;     category.CategoryName = "Mock Category";     var response = controller.Post(category);               // Assert     Assert.AreEqual(HttpStatusCode.Created, response.StatusCode);     var newCategory = JsonConvert.DeserializeObject<CategoryModel>(response.Content.ReadAsStringAsync().Result);     Assert.AreEqual(string.Format("http://localhost/api/category/{0}", newCategory.CategoryId), response.Headers.Location.ToString()); } [Test] public void Post_EmptyCategory_Returns_BadRequestStatusCode() {     // Arrange        commandBus.Setup(c => c.Submit(It.IsAny<CreateOrUpdateCategoryCommand>())).Returns(new CommandResult(true));     Mapper.CreateMap<CategoryFormModel, CreateOrUpdateCategoryCommand>();     var httpConfiguration = new HttpConfiguration();     WebApiConfig.Register(httpConfiguration);     var httpRouteData = new HttpRouteData(httpConfiguration.Routes["DefaultApi"],         new HttpRouteValueDictionary { { "controller", "category" } });     var controller = new CategoryController(commandBus.Object, categoryRepository.Object)     {         Request = new HttpRequestMessage(HttpMethod.Post, "http://localhost/api/category/")         {             Properties =             {                 { HttpPropertyKeys.HttpConfigurationKey, httpConfiguration },                 { HttpPropertyKeys.HttpRouteDataKey, httpRouteData }             }         }     };     // Act     CategoryModel category = new CategoryModel();     category.CategoryId = 0;     category.CategoryName = "";     // The ASP.NET pipeline doesn't run, so validation don't run.     controller.ModelState.AddModelError("", "mock error message");     var response = controller.Post(category);     // Assert     Assert.AreEqual(HttpStatusCode.BadRequest, response.StatusCode);   } In the above code block, we have written two unit methods, Post_Category_Returns_CreatedStatusCode and Post_EmptyCategory_Returns_BadRequestStatusCode. The unit test method Post_Category_Returns_CreatedStatusCode  verifies the behaviour 1 and 3, that we have defined in the beginning of the section “Unit Test for HTTP Post”. The unit test method Post_EmptyCategory_Returns_BadRequestStatusCode verifies the behaviour 2. For extracting the data from response, we call Content.ReadAsStringAsync().Result of HttpResponseMessage object and deserializeit it with Json Convertor. The implementation of HTTP Post in the CategoryController is provided below: // POST /api/category public HttpResponseMessage Post(CategoryModel category) {       if (ModelState.IsValid)     {         var command = new CreateOrUpdateCategoryCommand(category.CategoryId, category.CategoryName, category.Description);         var result = commandBus.Submit(command);         if (result.Success)         {                               var response = Request.CreateResponse(HttpStatusCode.Created, category);             string uri = Url.Link("DefaultApi", new { id = category.CategoryId });             response.Headers.Location = new Uri(uri);             return response;         }     }     else     {         return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);     }     throw new HttpResponseException(HttpStatusCode.BadRequest); } The unit test implementation for HTTP Put and HTTP Delete are very similar to the unit test we have written for  HTTP Get. The complete unit tests for the CategoryController is given below: [TestFixture] public class CategoryApiControllerTest { private Mock<ICategoryRepository> categoryRepository; private Mock<ICommandBus> commandBus; [SetUp] public void SetUp() {     categoryRepository = new Mock<ICategoryRepository>();     commandBus = new Mock<ICommandBus>(); } [Test] public void Get_All_Returns_AllCategory() {     // Arrange        IEnumerable<CategoryWithExpense> fakeCategories = GetCategories();     categoryRepository.Setup(x => x.GetCategoryWithExpenses()).Returns(fakeCategories);     CategoryController controller = new CategoryController(commandBus.Object, categoryRepository.Object)     {         Request = new HttpRequestMessage()                 {                     Properties = { { HttpPropertyKeys.HttpConfigurationKey, new HttpConfiguration() } }                 }     };     // Act     var categories = controller.Get();     // Assert     Assert.IsNotNull(categories, "Result is null");     Assert.IsInstanceOf(typeof(IEnumerable<CategoryWithExpense>),categories, "Wrong Model");             Assert.AreEqual(3, categories.Count(), "Got wrong number of Categories"); }        [Test] public void Get_CorrectCategoryId_Returns_Category() {     // Arrange        IEnumerable<CategoryWithExpense> fakeCategories = GetCategories();     categoryRepository.Setup(x => x.GetCategoryWithExpenses()).Returns(fakeCategories);     CategoryController controller = new CategoryController(commandBus.Object, categoryRepository.Object)     {         Request = new HttpRequestMessage()         {             Properties = { { HttpPropertyKeys.HttpConfigurationKey, new HttpConfiguration() } }         }     };     // Act     var response = controller.Get(1);     // Assert     Assert.AreEqual(HttpStatusCode.OK, response.StatusCode);     var category = JsonConvert.DeserializeObject<CategoryWithExpense>(response.Content.ReadAsStringAsync().Result);     Assert.AreEqual(1, category.CategoryId, "Got wrong number of Categories"); } [Test] public void Get_InValidCategoryId_Returns_NotFound() {     // Arrange        IEnumerable<CategoryWithExpense> fakeCategories = GetCategories();     categoryRepository.Setup(x => x.GetCategoryWithExpenses()).Returns(fakeCategories);     CategoryController controller = new CategoryController(commandBus.Object, categoryRepository.Object)     {         Request = new HttpRequestMessage()         {             Properties = { { HttpPropertyKeys.HttpConfigurationKey, new HttpConfiguration() } }         }     };     // Act     var response = controller.Get(5);     // Assert     Assert.AreEqual(HttpStatusCode.NotFound, response.StatusCode);            } [Test] public void Post_Category_Returns_CreatedStatusCode() {     // Arrange        commandBus.Setup(c => c.Submit(It.IsAny<CreateOrUpdateCategoryCommand>())).Returns(new CommandResult(true));     Mapper.CreateMap<CategoryFormModel, CreateOrUpdateCategoryCommand>();          var httpConfiguration = new HttpConfiguration();     WebApiConfig.Register(httpConfiguration);     var httpRouteData = new HttpRouteData(httpConfiguration.Routes["DefaultApi"],         new HttpRouteValueDictionary { { "controller", "category" } });

    // Act     CategoryModel category = new CategoryModel();     category.CategoryId = 1;     category.CategoryName = "Mock Category";     var response = controller.Post(category);               // Assert     Assert.AreEqual(HttpStatusCode.Created, response.StatusCode);     var newCategory = JsonConvert.DeserializeObject<CategoryModel>(response.Content.ReadAsStringAsync().Result);     Assert.AreEqual(string.Format("http://localhost/api/category/{0}", newCategory.CategoryId), response.Headers.Location.ToString()); } [Test] public void Post_EmptyCategory_Returns_BadRequestStatusCode() {     // Arrange        commandBus.Setup(c => c.Submit(It.IsAny<CreateOrUpdateCategoryCommand>())).Returns(new CommandResult(true));

• Include weather information in ASP.Net site from weather.com services

  - by sreejukg

  In this article, I am going to demonstrate how you can use the XMLOAP services (referred as XOAP from here onwards) provided by weather.com to display the weather information in your website. The XOAP services are available to be used for free of charge, provided you are comply with requirements from weather.com. I am writing this article from a technical point of view. If you are planning to use weather.com XOAP services in your application, please refer to the terms and conditions from weather.com website. In order to start using the XOAP services, you need to sign up the XOAP datafeed. The signing process is simple, you simply browse the url http://www.weather.com/services/xmloap.html. The URL looks similar to the following. Click on the sign up button, you will reach the registration page. Here you need to specify the site name you need to use this feed for. The form looks similar to the following. Once you fill all the mandatory information, click on save and continue button. That’s it. The registration is over. You will receive an email that contains your partner id, license key and SDK. The SDK available in a zipped format, contains the terms of use and documentation about the services available. Other than this the SDK includes the logos and icons required to display the weather information. As per the SDK, currently there are 2 types of information available through XOAP. These services are Current Conditions for over 30,000 U.S. and over 7,900 international Location IDs Updated at least Hourly Five-Day Forecast (today + 4 additional forecast days in consecutive order beginning with tomorrow) for over 30,000 U.S. and over 7,900 international Location IDs Updated at least Three Times Daily The SDK provides detailed information about the fields included in response of each service. Additionally there is a refresh rate that you need to comply with. As per the SDK, the refresh rate means the following “Refresh Rate” shall mean the maximum frequency with which you may call the XML Feed for a given LocID requesting a data set for that LocID. During the time period in between refresh periods the data must be cached by you either in the memory on your servers or in Your Desktop Application. About the Services Weather.com will provide you with access to the XML Feed over the Internet through the hostname xoap.weather.com. The weather data from the XML feed must be requested for a specific location. So you need a location ID (LOC ID). The XML feed work with 2 types of location IDs. First one is with City Identifiers and second one is using 5 Digit US postal codes. If you do not know your location ID, don’t worry, there is a location id search service available for you to retrieve the location id from city name. Since I am a resident in the Kingdom of Bahrain, I am going to retrieve the weather information for Manama(the capital of Bahrain) . In order to get the location ID for Manama, type the following URL in your address bar. http://xoap.weather.com/search/search?where=manama I got the following XML output. <?xml version="1.0" encoding="UTF-8"?> <!-- This document is intended only for use by authorized licensees of The –> <!-- Weather Channel. Unauthorized use is prohibited. Copyright 1995-2011, –> <!-- The Weather Channel Interactive, Inc. All Rights Reserved. –> <search ver="3.0">       <loc id="BAXX0001" type="1">Al Manama, Bahrain</loc> </search> You can try this with any city name, if the city is available, it will return the location id, and otherwise, it will return nothing. In order to get the weather information, from XOAP,  you need to pass certain parameters to the XOAP service. A brief about the parameters are as follows. Please refer SDK for more details. Parameter name Possible Value cc Optional, if you include this, the current condition will be returned. Value can be anything, as it will be ignored e.g. cc=* dayf If you want the forecast for 5 days, specify dayf=5 This is optional iink Value should be XOAP par Your partner id. You can find this in your registration email from weather.com prod Value should be XOAP key The license key assigned to you. This will be available in the registration email unit s or m (standard or matric or you can think of Celsius/Fahrenheit) this is optional field, if not specified the unit will be standard(s) The URL host for the XOAP service is http://xoap.weather.com. So for my purpose, I need the following request to be made to access the XOAP services. http://xoap.weather.com/weather/local/BAXX0001?cc=*&link=xoap&prod=xoap&par=*********&key=************** (The ***** to be replaced with the corresponding alternatives) The response XML have a root element “weather”. Under the root element, it has the following sections <head> - the meta data information about the weather results returned. <loc> - the location data block that provides, the information about the location for which the wheather data is retrieved. <lnks> - the 4 promotional links you need to place along with the weather display. Additional to these 4 links, there should be another link with weather channel logo to the home page of weather.com. <cc> - the current condition data. This element will be there only if you specify the cc element in the request. <dayf> - the forcast data as you specified. This element will be there only if you specify the dayf in the request. In this walkthrough, I am going to capture the weather information for Manama (Location ID: BAXX0001). You need 2 applications to display weather information in your website. A Console application that retrieves data from the XMLOAP and store in the SQL Server database (or any data store as you prefer).This application will be scheduled to execute in every 25 minutes using windows task scheduler, so that we can comply with the refresh rate. A web application that display data from the SQL Server database Retrieve the Weather from XOAP I have created a console application named, Weather Service. I created a SQL server database, with the following columns. I named the table as tblweather. You are free to choose any name. Column name Description lastUpdated Datetime, this is the last time when the weather data is updated. This is the time of the service running TemparatureDateTime The date and time returned by XML feed Temparature The temperature returned by the XML feed. TemparatureUnit The unit of the temperature returned by the XML feed iconId The id of the icon to be used. Currently 48 icons from 0 to 47 are available. WeatherDescription The Weather Description Phrase returned by the feed. Link1url The url to the first promo link Link1Text The text for the first promo link Link2url The url to the second promo link Link2Text The text for the second promo link Link3url The url to the third promo link Link3Text The text for the third promo link Link4url The url to the fourth promo link Link4Text The text for the fourth promo link Every time when the service runs, the application will update the database columns from the XOAP data feed. When the application starts, It is going to get the data as XML from the url. This demonstration uses LINQ to extract the necessary data from the fetched XML. The following are the code segment for extracting data from the weather XML using LINQ. // first, create an instance of the XDocument class with the XOAP URL. replace **** with the corresponding values.

For e.g. if you want to get the temperature, use item1.temp; Now I just need to execute an SQL query against the database. See the connection part. using (SqlConnection conn = new SqlConnection(@"Data Source=sreeju\sqlexpress;Initial Catalog=Sample;Integrated Security=True")) { string strSql = @"update tblweather set lastupdated=getdate(), temparatureDateTime = @temparatureDateTime, temparature=@temparature, temparatureUnit=@temparatureUnit, iconId = @iconId, description=@description, link1url=@link1url, link1text=@link1text, link2url=@link2url, link2text=@link2text,link3url=@link3url, link3text=@link3text,link4url=@link4url, link4text=@link4text"; SqlCommand comm = new SqlCommand(strSql, conn); comm.Parameters.AddWithValue("temparatureDateTime", item1.tempDate); comm.Parameters.AddWithValue("temparature", item1.temp); comm.Parameters.AddWithValue("temparatureUnit", item1.unit); comm.Parameters.AddWithValue("description", item1.description); comm.Parameters.AddWithValue("iconId", item1.iconId); var lstLinks = item1.links; comm.Parameters.AddWithValue("link1url", lstLinks.ElementAt(0).url); comm.Parameters.AddWithValue("link1text", lstLinks.ElementAt(0).text); comm.Parameters.AddWithValue("link2url", lstLinks.ElementAt(1).url); comm.Parameters.AddWithValue("link2text", lstLinks.ElementAt(1).text); comm.Parameters.AddWithValue("link3url", lstLinks.ElementAt(2).url); comm.Parameters.AddWithValue("link3text", lstLinks.ElementAt(2).text); comm.Parameters.AddWithValue("link4url", lstLinks.ElementAt(3).url); comm.Parameters.AddWithValue("link4text", lstLinks.ElementAt(3).text); conn.Open(); comm.ExecuteNonQuery(); conn.Close(); Console.WriteLine("database updated"); } Now click ctrl + f5 to run the service. I got the following output Check your database and make sure, the data is updated with the latest information from the service. (Make sure you inserted one row in the database by entering some values before executing the service. Otherwise you need to modify your application code to count the rows and conditionally perform insert/update query) Display the Weather information in ASP.Net page Now you got all the data in the database. You just need to create a web application and display the data from the database. I created a new ASP.Net web application with a default.aspx page. In order to comply with the terms of weather.com, You need to use Weather.com logo along with the weather display. You can find the necessary logos to use under the folder “logos” in the SDK. Additionally copy any of the icon set from the folder “icons” to your web application. I used the 93x93 icon set. You are free to use any other sizes available. The design view of the page in VS2010 looks similar to the following. The page contains a heading, an image control (for displaying the weather icon), 2 label controls (for displaying temperature and weather description), 4 hyperlinks (for displaying the 4 promo links returned by the XOAP service) and weather.com logo with hyperlink to the weather.com home page. I am going to write code that will update the values of these controls from the values stored in the database by the service application as mentioned in the previous step. Go to the code behind file for the webpage, enter the following code under Page_Load event handler. using (SqlConnection conn = new SqlConnection(@"Data Source=sreeju\sqlexpress;Initial Catalog=Sample;Integrated Security=True")) { SqlCommand comm = new SqlCommand("select top 1 * from tblweather", conn); conn.Open(); SqlDataReader reader = comm.ExecuteReader(); if (reader.Read()) { lblTemparature.Text = reader["temparature"].ToString() + "&deg;" + reader["temparatureUnit"].ToString(); lblWeatherDescription.Text = reader["description"].ToString(); imgWeather.ImageUrl = "icons/" + reader["iconId"].ToString() + ".png"; lnk1.Text = reader["link1text"].ToString(); lnk1.NavigateUrl = reader["link1url"].ToString(); lnk2.Text = reader["link2text"].ToString(); lnk2.NavigateUrl = reader["link2url"].ToString(); lnk3.Text = reader["link3text"].ToString(); lnk3.NavigateUrl = reader["link3url"].ToString(); lnk4.Text = reader["link4text"].ToString(); lnk4.NavigateUrl = reader["link4url"].ToString(); } conn.Close(); } Press ctrl + f5 to run the page. You will see the following output. That’s it. You need to configure the console application to run every 25 minutes so that the database is updated. Also you can fetch the forecast information and store those in the database, and then retrieve it later in your web page. Since the data resides in your database, you have the full control over your display. You need to make sure your website comply with weather.com license requirements. If you want to get the source code of this walkthrough through the application, post your email address below. Hope you enjoy the reading.

• How can I set my bootloader to load my primary (C:) partition?

  - by acidzombie24

  I created 4 partitions and want to use them to have seperate Windows XP, Windows 7, (possibly) Windows Vista installations, and "WinDummy" (to test applications in Vista, XP or another OS). I used Norton Ghost to install an OS to the drive in about 3 minutes. My problem is that I installed the spare first on the 4th partition, then Windows 7 on the second. I tried to set the bootloader (with easybcd) to use the first partition - but it doesn't want to. Heres my debug screen on easybcd As you can see, the device is set to H and i cant figure out how to change it. I can make my bootloader use Windows 7 first, but I can't make it use my C: install of XP instead of my spare H:. How would I fix this?

• E-mail from specific domain not delivered to one of the cc: recipients on Exchange 2010

  - by BobC

  we have a user on Exchange 2010 server who doesn't get email from one specific domain if her address is in cc: field. If she is a main recipient (To:) it goes through. We checked Exchange logs and it looks like our server doesn't even try to deliver it, it simply ignores her email address completely. We did several tests: send email with her email address in cc: field from another domain, succeeded send email with her email address in to: field from another domain, succeeded send email with her email address in to: field from affected domain, succeeded turn off all email rules check via webmail We also turned off firewall, antispam and antivirus for SMTP rule. Does anyone have any idea what could be an issue here? Thanks

  I have an xml file that I need to edit using Microsoft Word 2003. Everything works fine but the CDATA section is lost and is converted to normal html. For example <Description> <![CDATA[ <i> ]]> </Description> Gets converted to <Description> <i> </Description> Is there any way to preserve the CDATA section while editing in MS Word. I want to fix some typos and grammer in the xml file so I am using this approach. Thanks

• Send individual e-mails to each contact in Gmail?

  - by Robert C. Cartaino

  I'm trying to send an e-mail to a group of contacts in Gmail (200 recipients, no spam). Is there a way to force Gmail to send the e-mail as 200 individual e-mails, each addressed to that specific person in the list? But I'm trying to protect their privacy: Sending to a contact group puts all their e-mail addresses in the To: field. Adding their addresses to the cc: field means everyone can see all the addresses. Adding their addresses to the bcc: field means that no one sees their address (not even their own) in the to: field. That looks odd and seems like that would trigger a lot of spam filters. So how can I force Gmail to send the e-mail addressed specifically to each contact in the list?

• Cannot select fields with the mouse Windows 7

  - by Nick

  Lately I cannot select a word (field) with the mouse. When I left click on a field drag the mouse to the end of the field then release the button, the selection (blue shading) disappears. Sometimes after several tries the shading stays and I can delete the field. Up to a week ago everything worked fine. Is this a bug, virus? I am using Windows 7 Also, in Live Mail after I finished reading an item in the Inbox, I click the X in the upper right corner to return to the rest of my mail, but instead it takes me back to the desktop and have to double click the Live Mail again to continue. Again this only happened recently. Things worked OK before and this does not happen regularly.

• Why won't vyatta allow SMTP through my firewall?

  - by Solignis

  I am setting up a vyatta router on VMware ESXi, But I see to have hit a major snag, I could not get my firewall and NAT to work correctly. I am not sure what was wrong with NAT but it "seems" to be working now. But the firewall is not allowing traffic from my WAN interface (eth0) to my LAN (eth1). I can confirm its the firewall because I disabled all firewall rules and everything worked with just NAT. If put the firewalls (WAN and LAN) back in place nothing can get through to port 25. I am not really sure what the issue could be I am using pretty basic firewall rules, I wrote the rules while looking at the vyatta docs so unless there is something odd with the documentation they "should" be working. Here is my NAT rules so far; vyatta@gateway# show service nat rule 20 { description "Zimbra SNAT #1" outbound-interface eth0 outside-address { address 74.XXX.XXX.XXX } source { address 10.0.0.17 } type source } rule 21 { description "Zimbra SMTP #1" destination { address 74.XXX.XXX.XXX port 25 } inbound-interface eth0 inside-address { address 10.0.0.17 } protocol tcp type destination } rule 100 { description "Default LAN -> WAN" outbound-interface eth0 outside-address { address 74.XXX.XXX.XXX } source { address 10.0.0.0/24 } type source } Then here is my firewall rules, this is where I believe the problem is. vyatta@gateway# show firewall all-ping enable broadcast-ping disable conntrack-expect-table-size 4096 conntrack-hash-size 4096 conntrack-table-size 32768 conntrack-tcp-loose enable ipv6-receive-redirects disable ipv6-src-route disable ip-src-route disable log-martians enable name LAN_in { rule 100 { action accept description "Default LAN -> any" protocol all source { address 10.0.0.0/24 } } } name LAN_out { } name LOCAL { rule 100 { action accept state { established enable } } } name WAN_in { rule 20 { action accept description "Allow SMTP connections to MX01" destination { address 74.XXX.XXX.XXX port 25 } protocol tcp } rule 100 { action accept description "Allow established connections back through" state { established enable } } } name WAN_out { } receive-redirects disable send-redirects enable source-validation disable syn-cookies enable SIDENOTE To test for open ports I have using this website, http://www.yougetsignal.com/tools/open-ports/, it showed port 25 as open without the firewall rules and closed with the firewall rules. UPDATE Just to see if the firewall was working properly I made a rule to block SSH from the WAN interface. When I checked for port 22 on my primary WAN address it said it was still open even though I outright blocked the port. Here is the rule I used; rule 21 { action reject destination { address 74.219.80.163 port 22 } protocol tcp } So now I am convinced either I am doing something wrong or the firewall is not working like it should.
