  • Selecting a form which is in an iframe using jQuery

    - by Khnle
    I have a form inside an iframe which is inside a jQuery UI dialog box. The form contains a file input type. The jQuery UI dialog contains an Upload button. When this button is clicked, I would like to programmatically call the submit method. My question is how I could select the form which is in a iframe using jQuery. The following code should clarify the picture: <div id="upload_file_picker_dlg" title="Upload file"> <iframe id="upload_file_iframe" src="/frame_src_url" frameborder=0 width=100% scrolling=no></iframe> </div> frame_src_url contains: <form action="/UploadTaxTable" enctype="multipart/form-data" method="post" id="upload-form"> <p>Select a file to be uploaded:</p> <p> <input type="file" name="datafile" size="60"> </p> The jQueryUI dialog box javascript code: $('#upload_file_picker_dlg').dialog({ ... buttons: { 'Close': function() { $(this).dialog('close'); }, 'Upload': function() { $('#upload-form').submit(); //question is related to this line $(this).dialog('close'); } }, .... }); From the javascript code snippet above, how can I select the form with id upload-form that is in the iframe whose id is upload_file_iframe ?

If anyone can help id be much appreciative! Just for info, im using the jQuery form validation librairy, and here is my code: - $(document).ready(function(){ //Set Fields to be validated $("#EventForm").validate(); $( "#StartDate" ).datepicker(); $( "#EndDate" ).datepicker(); //Add Postcode Regex Method to Validator Function $.validator.addMethod( "postcode", function(value, element, regexp) { var check = false; var re = new RegExp(regexp); return this.optional(element) || re.test(value); }, "Please enter a valid postcode." ); //Add UK Telephone number Regex Method to Validator Function $.validator.addMethod( "telephone", function(value, element, regexp) { var check = false; var re = new RegExp(regexp); return this.optional(element) || re.test(value); }, "Please enter a valid UK telephone number in the format - 01856 666666." ); //Add Postcode Regular Expression Rule to Postcode Field $("#EventPostcode").rules("add", { postcode: "^([a-zA-Z]){1}([0-9][0-9]|[0-9]|[a-zA-Z][0-9][a-zA-Z]|[a-zA-Z][0-9][0-9]|[a-zA-Z][0-9]){1}([ ])([0-9][a-zA-z][a-zA-z]){1}$"}); $("#EventTelephoneNo").rules("add", { telephone: "^(((\+44\s?\d{4}|\(?0\d{4}\)?)\s?\d{3}\s?\d{3})|((\+44\s?\d{3}|\(?0\d{3}\)?)\s?\d{3}\s?\d{4})|((\+44\s?\d{2}|\(?0\d{2}\)?)\s?\d{4}\s?\d{4}))(\s?\#(\d{4}|\d{3}))?$"}); }); Many thanks

  • Initialize child models at model creation

    - by Antoine
    I have a model Entree which belongs to a model Vin, which itself belongs to a model Producteur. On the form for Entree creation/edition, I want to allow the user to define the attributes for parent Vin and Producteur to create them, or retrieve them if they exist (retrieval based on user input). For now I do the following in Entree new and edit actions: @entree = Entree.new @entree.vin = Vin.new @entree.vin.producteur = Producteur.new and use fields_for helper in the form,and that works. But I intend to have much more dependencies with more models, so I want to keep it DRY. I defined a after_initialize callback in Vin model which does the producteur initialization: class Vin < ActiveRecord::Base after_initialize :vin_setup def vin_setup producteur = Producteur.new end end and remove the producteur.new from the controller. However, get an error on new action: undefined method `model_name' for NilClass:Class for the line in the form that says <%= fields_for @entree.vin.producteur do |producteur| %> I guess that means the after_initialize callback doesn't act as I expect it. Is there something I'm missing? Also, I get the same error if I define a after_initialize method in the Vin model instead of definiing a callback.

  • testng multiple suites

    - by Eli
    Hi people. my problem is as follows: i am testing a web-ui using selenium and testng. i have a test suite with many test classes in it. i have a method with the @BeforeSuite witch also has a @Parameters annotation, this method recieves as a parameter the browser in witch the selenium will test by run,executing the lines: selenium = new DefaultSelenium("localhost", 4444, **browser**, "http://localhost:8099"); selenium.start(); the xml im using to run the test suite is: <suite name="suite"> <parameter name = "browser" value = "*firefox"/> <test name="allTests"> <classes> <class name="test.webui.MemcachedDeploymentTest" /> </classes> </test> </suite> this works fine and the test runs in firefox. my problem is that i would like to somehow run this suite again, immediatly after the first run finishes, but this time with chrome as the browser. i now have 2 xml suites, one with chrome and one with firefox, is there any way to run these test suites one after the other automatically? maybe using a third xml? Thanks in advance

  • Magento help with creating model in custom class

    - by dardub
    I'm trying to add some custom filter methods to my magento module. I though it would be simple but I can't figure out why it's not working. My model which extends the catalog/product class contains this: public function filterProdType($prod_id) { $this->addAttributeToFilter('attribute_set_id', $prod_id); } Then in my template I have this: $collection = Mage::getModel('configurator/product')->getCollection()->addAttributeToSelect('*'); $collection->filterProdType(50)->addAttributeToFilter('type_id', 'bundle'); foreach ($collection as $item){ echo $item->getName() . ', '; } Just to try things out. But I don't get any results, no error, and it doesn't finish rendering the page (missing footer). When I do this instead, it works: $collection = Mage::getModel('configurator/product')->getCollection()->addAttributeToSelect('*'); $collection->addAttributeToFilter('attribute_set_id', 50)->addAttributeToFilter('type_id', 'bundle'); foreach ($collection as $item){ echo $item->getName() . ', '; } I'm just wondering what I'm missing. UPDATE: I didn't realize error reporting was turned off, after turning it on I get the error: Fatal error: Call to undefined method Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Collection::filterProdType() I assumed after instantiating $collection using my custom model, it would find my new method.

  • Reference to the Main Form whilst trying to Serialize objects in C#

    - by Paul Matthews
    I have a button on my main form which calls a method to serialize some objects to disk. I am trying to add these objects to an ArrayList and then serialize them using a BinaryFormatter and a FileStream. public void SerializeGAToDisk(string GenAlgName) { // Let's make a list that includes all the objects we // need to store a GA instance ArrayList GAContents = new ArrayList(); GAContents.Add(GenAlgInstances[GenAlgName]); // Structure and info for a GA GAContents.Add(RunningGAs[GenAlgName]); // There may be several running GA's using (FileStream fStream = new FileStream(GenAlgName + ".ga", FileMode.Create, FileAccess.Write, FileShare.None)) { BinaryFormatter binFormat = new BinaryFormatter(); binFormat.Serialize(fStream, GAContents); } } When running the above code I get the following exception: System.Runtime.Serialization.SerializationException was unhandled Message=Type 'WindowsFormsApplication1.Form1' in Assembly 'GeneticAlgApp, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable. So that means that somewhere in the objects I'm trying to save there must be a reference to the main form. The only possible references I can see are 3 delegates which all point to methods in the main form code. Do delegates get serialized as well? I can't seem to apply the [NonSerialized] attribute to them. Is there anything else I might be missing? Even better, is there a quick method to find the reference(s) that are causing the problem?

  • Adding Categories to my Articles in my Rails app (Small Help)

    - by user214038
    I'm currently building a semi-small ruby app for a project. The problem I'm currently facing is the following: I want to be Able to fit the Article into the Categories. I've already accomplish this by having two models. An article model with a foreign key of category_id and my Category model with the name of the category. With a has_one and belogs_to relationship. (We're assuming you can only fit an article into one category). Here's the piece of code. This is the new method, where i create a new article and load up all the categories. def new @article = Article.new @categories = Category.find(:all) end The problem comes when i try to get the category from a combo box in order to insert it along with the article. This is the combo box code : f.select(:category_id,@categories) And this is the create method: def create @category = Category.find(params[:id]) @article = @category.articles.new(params[:article]) if @article.save flash[:notice] = "Article Submitted Sucessfully" redirect_to user_path else render :action = 'new' end end I believe that the problem i have is in this line when i try to load up the selected category "@category = Category.find(params[:id])" because whenever i hardcode the this line into @category = Category.find(1) It Works perfectly

  • C++ Storing variables and inheritance

    - by Kaa
    Hello Everyone, Here is my situation: I have an event driven system, where all my handlers are derived from IHandler class, and implement an onEvent(const Event &event) method. Now, Event is a base class for all events and contains only the enumerated event type. All actual events are derived from it, including the EventKey event, which has 2 fields: (uchar) keyCode and (bool)isDown. Here's the interesting part: I generate an EventKey event using the following syntax: Event evt = EventKey(15, true); and I ship it to the handlers: EventDispatch::sendEvent(evt); // void EventDispatch::sendEvent(const Event &event); (EventDispatch contains a linked list of IHandlers and calls their onEvent(const Event &event) method with the parameter containing the sent event. Now the actual question: Say I want my handlers to poll the events in a queue of type Event, how do I do that? x Dynamic pointers with reference counting sound like too big of a solution. x Making copies is more difficult than it sounds, since I'm only receiving a reference to a base type, therefore each time I would need to check the type of event, upcast to EventKey and then make a copy to store in a queue. Sounds like the only solution - but is unpleasant since I would need to know every single type of event and would have to check that for every event received - sounds like a bad plan. x I could allocate the events dynamically and then send around pointers to those events, enqueue them in the array if wanted - but other than having reference counting - how would I be able to keep track of that memory? Do you know any way to implement a very light reference counter that wouldn't interfere with the user? What do you think would be a good solution to this design? I thank everyone in advance for your time. Sincerely, Kaa

  • How to round-off hours based on Minutes(hours+0 if min<30, hours+1 otherwise) ?

    - by infant programmer
    I need to round-off the hours based on the minutes in a DateTime variable. The condition is: if minutes are less than 30, then minutes must be set to zero and no changes to hours, else if minutes =30, then hours must be set to hours+1 and minutes are again set to zero. Seconds are ignored. example: 11/08/2008 04:30:49 should become 11/08/2008 05:00:00 and 11/08/2008 04:29:49 should become 11/08/2008 04:00:00 I have written code which works perfectly fine, but just wanted to know a better method if could be written and also would appreciate alternative method(s). string date1 = "11/08/2008 04:30:49"; DateTime startTime; DateTime.TryParseExact(date1, "MM/dd/yyyy HH:mm:ss", null, System.Globalization.DateTimeStyles.None, out startTime); if (Convert.ToInt32((startTime.Minute.ToString())) > 29) { startTime = DateTime.Parse(string.Format("{0}/{1}/{2} {3}:{4}:{5}", startTime.Month.ToString(), startTime.Day.ToString(), startTime.Year.ToString(), startTime.Hour.ToString(), "00", "00")); startTime = startTime.Add(TimeSpan.Parse("01:00:00")); Console.WriteLine("startTime is :: {0}", startTime.ToString("MM/dd/yyyy HH:mm:ss")); } else { startTime = DateTime.Parse(string.Format("{0}/{1}/{2} {3}:{4}:{5}", startTime.Month.ToString(), startTime.Day.ToString(), startTime.Year.ToString(), startTime.Hour.ToString(), "00", "00")); Console.WriteLine("startTime is :: {0}", startTime.ToString("MM/dd/yyyy HH:mm:ss")); }

  • Best way to associate data files with particular tests in RSpec / Ruby

    - by Bill T
    For my RSpec tests I would to automatically associate data files with each test. To clarify, if my tests each require an xml file as input data and then some xpath statements to validate the responses they get back I would like to externalize the xml and xpath as files and have the testing framework easily associate them with the particular test being run by using the unique ID of the test as the file(s) name. I tried to get this behavior but the solution isn't very clean. I wrote a helper method that takes the value of "description" and combines it with FILE to create a unique identifier which is set into a global variable that other utilities can access. The unique identifier is used to associate the data files I need. I have to call this helper method as the first line of every test, which is ugly. If I have an RSpec example that looks like this: describe "Basic functions of this server I'm testing" do it "should give me back a response" do # Sets a global var to: "my_tests_spec.rb_should_give_me_back_a_response" TestHelper::who_am_i __FILE__, description ... end end Is there some better/cleaner/slicker way I can get an unique ID for each test that I could use to associate data files with? Perhaps something build into RSpec I'm unaware of? Thank you, -Bill

  • Comparing strings that contain formatting in C#

    - by Finglas
    I'm working on a function that given some settings - such as line spacing, the output (in string form) is modified. In order to test such scenarios, I'm using string literals, as shown below for the expected result. The method, using a string builder, (AppendLine) generates the said output. One issue I have run into is that of comparing such strings. In the example below, both are equal in terms of what they represent. The result is the area which I care about, however when comparing two strings, one literal, one not, equality naturally fails. This is because one of the strings emits line spacing, while the other only demonstrates the formatting it contains. What would be the best way of solving this equality problem? I do care about formatting such as new lines from the result of the method, this is crucially important. Code: string expected = @"Test\n\n\nEnd Test."; string result = "Test\n\n\nEnd Test"; Console.WriteLine(expected); Console.WriteLine(result); Output: Test\n\n\nEnd Test. Test End Test

  • How to Implement an Interface that Requires Duplicate Member Names?

    - by Will Marcouiller
    I often have to implement some interfaces such as IEnumerable<T> in my code. Each time, when implementing automatically, I encounter the following: public IEnumerator<T> GetEnumerator() { // Code here... } public IEnumerator GetEnumerator1() { // Code here... } Though I have to implement both GetEnumerator() methods, they impossibly can have the same name, even if we understand that they do the same, somehow. The compiler can't treat them as one being the overload of the other, because only the return type differs. When doing so, I manage to set the GetEnumerator1() accessor to private. This way, the compiler doesn't complaint about not implementing the interface member, and I simply throw a NotImplementedException within the method's body. However, I wonder whether it is a good practice, or if I shall proceed differently, as perhaps a method alias or something like so. What is the best approach while implementing an interface such as IEnumerable<T> that requires the implementation of two different methods with the same name? EDIT #1 Does VB.NET reacts differently from C# while implementing interfaces, since in VB.NET it is explicitly implemented, thus forcing the GetEnumerator1(). Here's the code: Public Function GetEnumerator() As System.Collections.Generic.IEnumerator(Of T) Implements System.Collections.Generic.IEnumerable(Of T).GetEnumerator // Code here... End Function Public Function GetEnumerator1() As System.Collections.Generic.IEnumerator Implements System.Collections.Generic.IEnumerable.GetEnumerator // Code here... End Function Both GetEnumerator() methods are explicitly implemented, and the compile will refuse them to have the same name. Why?

  • [java] Returning the element number of the longest string in an array

    - by JohnRoberts
    Hoookay, so. I'm trying to get the longestS method to take the user-inputted array of strings, then return the element number of the longest string in that array. I got it to the point where I was able to return the number of chars in the longest string, but I don't believe that will work for what I need. My problem is that I keep getting incompatible type errors when trying to figure this out. I don't understand the whole data type thing with strings yet. It's confusing me how I go about return a number of the array yet the array is of strings. The main method is fine, I got stuck on the ???? part. { public static void main(String [] args) { Scanner inp = new Scanner( System.in ); String [] responseArr= new String[4]; for (int i=0; i<4; i++) { System.out.println("Enter string "+(i+1)); responseArr[i] = inp.nextLine(); } int highest=longestS(responseArr); } public static int longestS(String[] values) { int largest=0 for( int i = 1; i < values.length; i++ ) { if ( ????? ) } return largest; } }

  • Mocking non-virtual methods in C++ without editing production code?

    - by wk1989
    Hello, I am a fairly new software developer currently working adding unit tests to an existing C++ project that started years ago. Due to a non-technical reason, I'm not allowed to modify any existing code. The base class of all my modules has a bunch of methods for Setting/Getting data and communicating with other modules. Since I just want to unit testing each individual module, I want to be able to use canned values for all my inter-module communication methods. I.e. for a method Ping() which checks if another module is active, I want to have it return true or false based on what kind of test I'm doing. I've been looking into Google Test and Google Mock, and it does support mocking non-virtual methods. However the approach described (http://code.google.com/p/googlemock/wiki/CookBook#Mocking_Nonvirtual_Methods) requires me to "templatize" the original methods to take in either real or mock objects. I can't go and templatize my methods in the base class due to the requirement mentioned earlier, so I need some other way of mocking these virtual methods Basically, the methods I want to mock are in some base class, the modules I want to unit test and create mocks of are derived classes of that base class. There are intermediate modules in between my base Module class and the modules that I want to test. I would appreciate any advise! Thanks, JW EDIT: A more concrete examples My base class is lets say rootModule, the module I want to test is leafModule. There is an intermediate module which inherits from rootModule, leafModule inherits from this intermediate module. In my leafModule, I want to test the doStuff() method, which calls the non virtual GetStatus(moduleName) defined in the rootModule class. I need to somehow make GetStatus() to return a chosen canned value. Mocking is new to me, so is using mock objects even the right approach?

  • When are predicates appropriate and what is the best pattern for usage

    - by Maxim Gershkovich
    When are predicates appropriate and what is the best pattern for usage? What are the advantages of predicates? It seems to me like most cases where a predicate can be employed a tight loop would accomplish the same functionality? I don’t see a reusability argument given you will probably only implement a predicate in one method right? They look and feel nice but besides that they seem like you would only employ them when you need a quick hack on the collection classes? UPDATE But why would you be rewriting the tight loop again and again? In my mind/code when it comes to collections I always end up with something like Class Person End Class Class PersonList Inherits List(Of Person) Function FindByName(Name) as Person tight loop.... End Function End Class @Ani By that same logic I could implement the method as such Class PersonList Inherits List(Of Person) Function FindByName(Name) as PersonList End Function Function FindByAge(Age) as PersonList End Function Function FindBySocialSecurityNumber(SocialSecurityNumber) as PersonList End Function End Class And call it as such Dim res as PersonList = MyList.FindByName("Max").FindByAge(25).FindBySocialSecurityNumber(1234) and the result along with the amount of code and its reusability is largely the same, no? I am not arguing just trying to understand.

  • Getting the last User ID in Zend Framework

    - by Ryan Murphy
    Using MySQL query browser, I manually made a table called users and input some date in the fields. I set the primary key to id and set it to auto increment. There are 3 rows, the highest id is 3. I then made the following class in the method directory to call upon the data in the table etc. class Application_Model_DbTable_User extends Zend_Db_Table_Abstract { protected $_name = 'user'; public function getLatestUserId() { $id = $this->getAdapter()->lastInsertId(); return $id; } } In the controller I do the following which gets the value generated by the method and lets the view access it: $usersDbModel = new Application_Model_DbTable_User(); $lastUserId = $usersDbModel->getLatestUserId(); $this->view->lastUserId = $lastUserId; In the view I then echo it to display it to the user: echo $this->lastUserId; However, even though my last id in the users table is 3. It displays 0. I have also tried: public function getLatestUserId() { $sql = 'SELECT max(id) FROM user'; $query = $this->query($sql); $result = $query->fetchAll(); return $result; } But this just throws out a server error. What have I done wrong? Am I missing something? Is there another way of doing this?

  • Custom UIButton Memory Management in dealloc

    - by ddawber
    I am hoping to clarify the processes going on here. I have created a subclass of UIButton whose init method looks like this: - (id)initWithTitle:(NSString *)title frame:(CGRect)btnFrame { self = [UIButton buttonWithType:UIButtonTypeCustom]; [self setTitle:title forState:UIControlStateNormal]; self.frame = btnFrame; return self; } In my view controller I am creating one of these buttons and adding it as a subview: myButton = [[CustomButton alloc] initWithTitle:@"Title" frame:someFrame]; [self.view addSubview:myButton]; In the view controller's dealloc method I log the retain count of my button: - (void)dealloc { NSLog(@"RC: %d", [myButton retainCount]); //RC = 2 [super dealloc]; NSLog(@"RC: %d", [myButton retainCount]); //RC = 1 } The way I understand it, myButton is not actually retained, even though I invoked it using alloc, because in my subclass I created an autorelease button (using buttonWithType:). In dealloc, does this mean that, when dealloc is called the superview releases the button and its retain count goes down to 1? The button has not yet been autoreleased? Or do I need to get that retain count down to zero after calling [super dealloc]? Cheers.

  • What's the correct place to share application logic in CakePHP?

    - by Pichan
    I guess simple answer to the question would be a component. Although I agree, I feel weird having to write a component for something so specific. For example, let's say I have a table of users. When a user is created, it should form a chain reaction of events, initiating different kinds of data related to the user all around the database. I figured it would be best to avoid directly manipulating the database from different controllers and instead pack all that neatly in a method. However since some logic needs to be accesed separately, I really can't have the whole package in a single method. Instead I thought it would be logical to break it up to smaller pieces(like $userModelOrController->createNew() and $candyStorageModelOrController->createNew()) that only interact with their respective database table. Now, if the logic is put to the model, it works great until I need to use other models. Of course it's possible, but when compared to loading models in a controller, it's not that simple. It's like a Cake developer telling me "Sure, it's possible if you want to do it that way but that's not how I would do it". Then, if the logic is put to the controller, I can access other models really easy through $this->loadModel(), but that brings me back to the previously explained situation since I need to be able to continue the chain reaction indefinitely. Accessing other controllers from a controller is possible, but again there doesn't seem to be any direct way of doing so, so I'm guessing I'm still not doing it right. By using a component this problem could be solved easily, since components are available to every controller I want. But like I wrote at the beginning, it feels awkward to create a component specifically for this one task. To me, components seem more like packages of extra functionality(like the core components) and not something to share controller-specific logic. Since I'm new to this whole MVC thing, I could've completely misunderstood the concept. Once again, I would be thankful if someone pointed me to the right direction :)

  • How can I design a custom control in Javascript (possibly using jQuery)

    - by Mathieu Pagé
    I'd like to create a custom control in javascript. The goal is to create a building block that has methods, properties and events and render into a div. An example of one such control would be a calendar. It would render into a div, it would have properties that would define how it's displayed and what date is selected or highlighted, it would have methods to change the current month or to select some date and it would raise events when a day is clicked or the current month is changed by a user input. I can think of lots of way to implement this and I'm not sure what is the best way. I seem to remember that it's a bad thing to augment a DOM elements with properties and method, so I ruled that out. A jQuery plugin seems like a good idea, however I'm not sure if it's appropriate to create a plugin for each and every method my control would have so I could then use it like : $('#control').method1(); $('#control').method2(); And if I do use jQuery, where do I store the private data of my control? Another idea I got was to create a new kind of object that would have a reference to a div in which it could render it's elements. So what is the prefered way to do this. If I can I would like to do this as a jQuery plugin, but I'd need guidlines on how to create methods and where to store private data. I've loked at Plugins/Authoring on jQuery website and it did not helped that much in this regard.

  • Self referencing userdata and garbage collection

    - by drtwox
    Because my userdata objects reference themselves, I need to delete and nil a variable for the garbage collector to work. Lua code: obj = object:new() -- -- Some time later obj:delete() -- Removes the self reference obj = nil -- Ready for collection C Code: typedef struct { int self; // Reference to the object // Other members and function references removed } Object; // Called from Lua to create a new object static int object_new( lua_State *L ) { Object *obj = lua_newuserdata( L, sizeof( Object ) ); // Create the 'self' reference, userdata is on the stack top obj->self = luaL_ref( L, LUA_REGISTRYINDEX ); // Put the userdata back on the stack before returning lua_rawgeti( L, LUA_REGISTRYINDEX, obj->self ); // The object pointer is also stored outside of Lua for processing in C return 1; } // Called by Lua to delete an object static int object_delete( lua_State *L ) { Object *obj = lua_touserdata( L, 1 ); // Remove the objects self reference luaL_unref( L, LUA_REGISTRYINDEX, obj->self ); return 0; } Is there some way I can set the object to nil in Lua, and have the delete() method called automatically? Alternatively, can the delete method nil all variables that reference the object? Can the self reference be made 'weak'?

  • Setting the height of a row in a JTable in java

    - by Douglas Grealis
    I have been searching for a solution to be able to increase the height of a row in a JTable. I have been using the setRowHeight(int int) method which compiles and runs OK, but no row[s] have been increased. When I use the getRowHeight(int) method of the row I set the height to, it does print out the size I increased the row to, so I'm not sure what is wrong. The code below is a rough illustration how I am trying to solve it. My class extends JFrame. String[] columnNames = {"Column 1", "Column 2", "Column 1 3"}; JTable table = new JTable(new DefaultTableModel(columnNames, people.size())); DefaultTableModel model = (DefaultTableModel) table.getModel(); int count =1; for(Person p: people) { model.insertRow(count,(new Object[]{count, p.getName(), p.getAge()+"", p.getNationality})); count++; } table.setRowHeight(1, 15);//Try set height to 15 (I've tried higher) Can anyone tell me where I am going wrong? I am trying to increase the height of row 1 to 15 pixels?

    I've come across a strange behaviour in .NET/Reflection and cannot find any solution/explanation for this: Class A { public string TestString { get; set; } } Class B : A { public override string TestString { get { return "x"; } } } Since properties are just pairs of functions (get_PropName(), set_PropName()) overriding only the "get" part should leave the "set" part as it is in the base class. And this is just what happens if you try to instanciate class B and assign a value to TestString, it uses the implementation of class A. But what happens if I look at the instantiated object of class B in reflection is this: PropertyInfo propInfo = b.GetType().GetProperty("TestString"); propInfo.CanRead ---> true propInfo.CanWrite ---> false(!) And if I try to invoke the setter from reflection with: propInfo.SetValue("test", b, null); I'll even get an ArgumentException with the following message: Property set method not found. Is this as expected? Because I don't seem to find a combination of BindingFlags for the GetProperty() method that returns me the property with a working get/set pair from reflection.

  • Surely a foolish error, but I can't see it

    - by dnagirl
    I have a form (greatly simplified): <form action='http://example.com/' method='post' name='event_form'> <input type='text' name='foo' value='3'/> <input type='submit' name='event_submit' value='Edit'/> </form> And I have a class "EventForm" to process the form. The main method, process() looks like this: public function process($submitname=false){ $success=false; if ($submitname && isset($_POST[$submitname])){ //PROBLEM: isset($_POST[$submitname] is always FALSE for some reason if($success=$this->ruler->validate()){//check that dependancies are honoured and data types are correct if($success=$this->map_fields()){//divide input data into Event, Schedule_Element and Temporal_Expression(s) $success=$this->eventholder->save(); } } } else {//get the record from the db based on event_id or schedule_element_id foreach($this->gets as $var){//list of acceptable $_GET keys if(isset($_GET[$var])){ if($success= $this->__set($var,$_GET[$var])) break; } } } $this->action=(empty($this->eventholder->event_id))? ADD : EDIT; return $success; } When the form is submitted, this happens: $form->process('event_submit'); For some reason though, isset($_POST['event_submit']) always evaluates to FALSE. Can anyone see why?

  • Java - problems iterating through an ArrayList

    - by cc0
    Ok so I have an ArrayList (arrBok), which is full of book objects (the code is in Norwegian, so pay no attention to that please). I want to make a public method which iterates through all the objects in the arraylist. When I execute the code, it just seems to run in an infinite loop, not producing any return values. Here is the relevant (I hope, because there are a couple of other classes involved) part of the code; public String listAll() { itr = arrBok.iterator(); while (itr.hasNext()) { i++; } return "lol"; } This code does nothing useful, but I just want to see if it can iterate through it successfully. What I have tried so far; Tested if the bokArr (arraylist) is empty, which it's not. It has 4 objects inside of it. Return the toString() method of the itr, with the following result; java.util.AbstractList$Itr@173a10f // <-- not sure if this would be relevant to anything return itr.next().toString(); <-- // which seems to return the first object in the array, does that make sense?

  • Cannot overload function

    - by anio
    So I've got a templatized class and I want to overload the behavior of a function when I have specific type, say char. For all other types, let them do their own thing. However, c++ won't let me overload the function. Why can't I overload this function? I really really do not want to do template specialization, because then I've got duplicate the entire class. Here is a toy example demonstrating the problem: http://codepad.org/eTgLG932 The same code posted here for your reading pleasure: #include <iostream> #include <cstdlib> #include <string> struct Bar { std::string blah() { return "blah"; } }; template <typename T> struct Foo { public: std::string doX() { return m_getY(my_t); } private: std::string m_getY(char* p_msg) { return std::string(p_msg); } std::string m_getY(T* p_msg) { return p_msg->blah(); } T my_t; }; int main(int, char**) { Foo<char> x; Foo<Bar> y; std::cout << "x " << x.doX() << std::endl; return EXIT_SUCCESS; } Thank you everyone for your suggestions. Two valid solutions have been presented. I can either specialize the doX method, or specialize m_getY() method. At the end of the day I prefer to keep my specializations private rather than public so I'm accepting Krill's answer.
