  • Create an Xml file from an object (c#)

    - by remi bourgarel
    Hi All, I work as a web developer with a web designer and we usually do like this : - I create the system , I generate some Xml files - the designer display the xml files with xslt Nothing new. My problem is that I use Xml Serialization to create my xml files, but I never use Deserialization. So I'd like to know if there is a way to avoid fix like these : empty setter for my property empty parameter-less constructor implement IXmlSerializable and throw "notimplementedexception" on deserialization do a copy of the class with public fields thanks.

  • Finding the closest object in proxmity to the mouse Coordinates

    - by Cam
    Hey there, i've been working on a problem for a while now, which involves targeting the closest movieClip in relation to the x y coords of the mouse, I've attached a nice little acompanying graphic. Each mc added to the stage has it's own sub-class (HotSpots) which uses Pythag to measure distance from mouse. At this stage i can determine the closest value from my Main class but can't figure out how to reference it back to the movieclip... hope this makes sense. Below are the two Classes. My Main Class which attachs the mcs, and monitors mouse movement and traces closest value package { import flash.display.*; import flash.text.*; import flash.events.*; public class Main extends MovieClip { var pos:Number = 50; var nodeArray:Array; public function Main(){ nodeArray = []; for(var i:int = 0; i < 4; i++) { var hotSpot_mc:HotSpots = new HotSpots; hotSpot_mc.x += pos; hotSpot_mc.y += pos; addChild(hotSpot_mc); nodeArray.push(hotSpot_mc); // set some pos pos += 70; } stage.addEventListener(MouseEvent.MOUSE_MOVE,updateProxmity) } public function updateProxmity(e:MouseEvent):void { var tempArray:Array = new Array(); for(var i:int = 0; i < 4; i++) { this['tf'+[i]].text = String(nodeArray[i].dist); tempArray.push(nodeArray[i].dist); } tempArray.sort(Array.NUMERIC); var minValue:int = tempArray[0]; trace(minValue) } } } My HotSpots Class package { import flash.display.MovieClip; import flash.events.Event; import flash.text.TextField; public class HotSpots extends MovieClip { public var XSide:Number; public var YSide:Number; public var dist:Number = 0; public function HotSpots() { addEventListener(Event.ENTER_FRAME, textUp); } public function textUp(event:Event):void { XSide = this.x - MovieClip(root).mouseX; YSide = this.y - MovieClip(root).mouseY; dist = Math.round((Math.sqrt(XSide*XSide + YSide*YSide))); } } } thanks in advance

  • Shape object in Processing, translate individual shapes.

    - by Zain
    I am relatively new to Processing but have been working in Java for about 2 years now. I am facing difficulty though with the translate() function for objects as well as objects in general in processing. I went through the examples and tried to replicate the manners by which they instantiated the objects but cannot seem to even get the shapes to appear on the screen no less move them. I instantiate the objects into an array using a nested for loop and expect a grid of the objects to be rendered. However, nothing at all is rendered. My nested for loop structure to instantiate the tiles: for(int i=0; i<102; i++){ for(int j=0; j<102; j++){ tiles[i][j]=new tile(i,0,j); tiles[i][j].display(); } } And the constructors for the tile class: tile(int x, int y, int z){ this.x=x; this.y=y; this.z=z; beginShape(); vertex(x,y,z); vertex(x+1,y,z); vertex(x+1,y,z-1); vertex(x,y,z-1); endShape(); } Nothing is rendered at all when this runs. Furthermore, if this is of any concern, my translations(movements) are done in a method I wrote for the tile class called move which simply calls translate. Is this the correct way? How should one approach this? I can't seem to understand at all how to render/create/translate individual objects/shapes. Thanks for any help any of you are able to provide!

  • Passing Object to Service in WCF

    - by hgulyan
    Hi, I have my custom class Customer with its properties. I added DataContract mark above the class and DataMember to properties and it was working fine, but I'm calling a service class's function, passing customer instance as parameter and some of my properties get 0 values. While debugging I can see my properties values and after it gets to the function, some properties' values are 0. Why it can be so? There's no code between this two actions. DataContract mark workes fine, everything's ok. Any suggestions on this issue? I tried to change ByRef to ByVal, but it doesn't change anything. Why it would pass other values right and some of integer types just 0? Maybe the answer is simple, but I can't figure it out. Thank You. <DataContract()> Public Class Customer Private Type_of_clientField As Integer = -1 <DataMember(Order:=1)> Public Property type_of_client() As Integer Get Return Type_of_clientField End Get Set(ByVal value As Integer) Type_of_clientField = value End Set End Property End Class <ServiceContract(SessionMode:=SessionMode.Allowed)> <DataContractFormat()> Public Interface CustomerService <OperationContract()> Function addCustomer(ByRef customer As Customer) As Long End Interface type_of_client properties value is 6 before I call addCustomer function. After it enters that function the value is 0. UPDATE: The issue is in instance creating. When I create an instance of a class on client side, that is stored on service side, some of my properties pass 0 or nothing, but when I call a function of a service class, that returns a new instance of that class, it works fine. What's is the difference? Could that be serialization issue?

  • HTML5 move Canvas object

    - by Mircea
    Hi, I have 2 canvas created on the same canvas. Is it possible to drag the small black one around? I want to make it draggable but I can not find any online tutorial or demo on this. Is it possible? I had looked to Canvas moveTo or transitions but I was unable to make it work. The code is here http://jsfiddle.net/35P9F/2/ var ctx = document.getElementById('canvas').getContext('2d'); var radgrad3 = ctx.createLinearGradient(255,10,0,180,80,190); radgrad3.addColorStop(0, '#00C9FF'); radgrad3.addColorStop(1, 'red'); ctx.fillStyle = radgrad3; ctx.fillRect(0,0,255,255); var ctx4 = document.getElementById('canvas').getContext('2d'); var radgrad4 = ctx4.createLinearGradient(0, 0, 0, 255); radgrad4.addColorStop(0, '#000000'); radgrad4.addColorStop(1, '#ff0000'); ctx4.fillStyle = radgrad4; ctx4.fillRect(0,0,25,25); Thank you.

  • PHP Image Upload object won't create directory on windows

    - by ThinkingInBits
    I'm writing a class that excepts a product_id and a $_FILES array as it's constructor. The class saves these variables and uses them to create a new directory named by product_id and attempts to copy the temp file to my specified directory. For some reason my class isn't even getting as far as creating a directory (which should happen in the constructor) Here's a link to my code: http://pastie.org/955454

  • bring object to front flash actionscript 3

    - by steve
    I have a menu set up that has about 20 menu items in a circle. When you mouse over each item, a title comes up. The only problem is that because of the depth order, it's hidden behind the other menu items. Is there a way to bring this item to the front when moused over? I'm pretty actionscript illiterate so any help would be awesome.

  • Strange GWT serialization exception when overiding method of serialized object

    - by Flueras Bogdan
    Hi there! I have a GWT serializable class, lets call it Foo. Foo implements IsSerializable, has primitive and serializable members as well as other transient members and a no-arg constructor. class Foo implements IsSerializable { // transient members // primitive members public Foo() {} public void bar() {} } Also a Service which handles RPC comunication. // server code public interface MyServiceImpl { public void doStuff(Foo foo); } public interface MyServiceAsync { void doStuff(Foo foo, AsyncCallback<Void> async); } How i use this: private MyServiceAsync myService = GWT.create(MyService.class); Foo foo = new Foo(); ... AsyncCallback callback = new new AsyncCallback {...}; myService.doStuff(foo, callback); In the above case the code is running, and the onSuccess() method of callback instance gets executed. But when I override the bar() method on foo instance like this: Foo foo = new Foo() { public void bar() { //do smthng different } } AsyncCallback callback = new new AsyncCallback {...}; myService.doStuff(foo, callback); I get the GWT SerializationException. Please enlighten me, because I really don't understand why.

  • How to load object after saving with encodeWithCoder?

    - by fuzzygoat
    EDIT_002: Further rewrite: if I save using the method below how would the method to load it back in look? (moons is an NSMutableArray of NSNumbers) // ------------------------------------------------------------------- ** // METHOD_002 // ------------------------------------------------------------------- ** -(void)saveMoons:(NSString *)savePath { NSMutableData *data = [[NSMutableData alloc] init]; NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data]; [moons encodeWithCoder:archiver]; [archiver finishEncoding]; [data writeToFile:savePath atomically:YES]; [archiver release]; [data release]; } EDIT_003: Found it, my problem was that I was using ... [moons encodeWithCoder:archiver]; where I should have been using ... [archiver encodeObject:moons]; Hence the loader would look like: -(void)loadMoons_V3:(NSString *)loadPath { NSData *data = [[NSData alloc] initWithContentsOfFile:loadPath]; NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data]; [self setMoons:[unarchiver decodeObject]]; [unarchiver finishDecoding]; [unarchiver release]; [data release]; } gary

  • pass object from JS to PHP and back

    - by Radu
    This is something that I don't think can't be done, or can't be done easy. Think of this, You have an button inside a div in HTML, when you click it, you call a php function via AJAX, I would like to send the element that start the click event(or any element as a parameter) to PHP and BACK to JS again, in a way like serialize() in PHP, to be able to restore the element in JS. Let me give you a simple example: PHP: function ajaxCall(element){ return element; } JS: callbackFunction(el){ el.color='red'; } HTML: <div id="id_div"> <input type="button" value="click Me" onClick="ajaxCall(this, callbackFunction);" /> </div> So I thing at 3 methods method 1. I can give each element in the page an ID. so the call to Ajax would look like this: ajaxCall(this.id, callbackFunction); and the callback function would be: document.getElementById(el).color='red'; This method I think is hard, beacause in a big page is hard to keep track of all ID's. method 2. I think that using xPath could be done, If i can get the exact path of an element, and in the callback function evaluate that path to reach the element. This method needs some googling, it is just an ideea. method 3. Modify my AJAX functions, so it retain the element that started the event, and pass it to the callback function as argument when something returns from PHP, so in my AJAX would look like this: eval(callbackFunction(argumentsFromPhp, element)); and the callback function would be: callbackFunction(someArgsFromPhp, el){ el.color='red'; // parse someArgsFromPhp } I think that the third option is my choise to start this experiment. Any of you has a better idea how I can accomplish this ? Thank you.

  • Reliable way to get the "ancestor" of an object with a specific classname, using jQuery

    - by Matt Dawdy
    I've got a javascript function that gets called on change event of a select form element. So, the "this" variable in js refers to the select element. This select element is in a td tag, in a tr tag. The tr tag has a classname of "FilterDetailsRow". Now, I've tested, and if I use this syntax: var filterRow = $(this).parent().parent(); it gets me what I want. However, is there a better way to tell jQuery, "starting with "this" can you please go up my tree of parents until you find one with a classname of "FilterDetailsRow"? Here's what I came up with, but I want to make sure I"m not reinventing the wheel. function GetFilterDetailsRowOfObject(o) { if (o) { if (o.parent()[0].className.indexOf("FilterDetailsRow") != -1) return o; else return GetFilterDetailsRowOfObject(o.parent()); } else { return null; } } Thanks for any advice.

  • Save PyML.classifiers.multi.OneAgainstRest(SVM()) object?

    - by Michael Aaron Safyan
    I'm using PYML to construct a multiclass linear support vector machine (SVM). After training the SVM, I would like to be able to save the classifier, so that on subsequent runs I can use the classifier right away without retraining. Unfortunately, the .save() function is not implemented for that classifier, and attempting to pickle it (both with standard pickle and cPickle) yield the following error message: pickle.PicklingError: Can't pickle : it's not found as __builtin__.PySwigObject Does anyone know of a way around this or of an alternative library without this problem? Thanks. Edit/Update I am now training and attempting to save the classifier with the following code: mc = multi.OneAgainstRest(SVM()); mc.train(dataset_pyml,saveSpace=False); for i, classifier in enumerate(mc.classifiers): filename=os.path.join(prefix,labels[i]+".svm"); classifier.save(filename); Notice that I am now saving with the PyML save mechanism rather than with pickling, and that I have passed "saveSpace=False" to the training function. However, I am still gettting an error: ValueError: in order to save a dataset you need to train as: s.train(data, saveSpace = False) However, I am passing saveSpace=False... so, how do I save the classifier(s)? P.S. The project I am using this in is pyimgattr, in case you would like a complete testable example... the program is run with "./pyimgattr.py train"... that will get you this error. Also, a note on version information: [michaelsafyan@codemage /Volumes/Storage/classes/cse559/pyimgattr]$ python Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. import PyML print PyML.__version__ 0.7.0

  • Delphi memory management design strategies : Object or Interface ?

    - by Pierre-Jean Coudert
    Regarding Delphi memory management, what are your design strategies ? What are the use cases where you prefer to create and release Objects manually ? What are the uses cases where Interfaces, InterfacedObjects, and their reference counting mechanism will be prefered ? Do you have identified some traps or difficulties with reference counted objects ? Thanks for sharing your experience here.

  • Error in R for missing object

    - by griffin
    I have several nested functions, some of which as called in lapply clauses. In the process, sometimes I don't set a default for a parameter and instead check if it was supplied using the missing function. I'm getting a strange error right now when I'm not passing a value for a parameter, it has no default, yet missing resolves to FALSE. And when I try to use or check the parameter in any other way (using length, exists, etc.), I get an error: Error in try(length(x)) : argument "data" is missing, with no default Has anyone experienced this failure of the missing function before?

  • Recommendations on Triming Large Amounts of Text from a DOM Object

    - by aronchick
    I'm doing some in browser editing, and I have some content that's on the order of around 20k characters long in a <pre>. So it looks something like: <pre> Text 1 Text 2 Text 3 Text 4 [...] Text 20,000 </pre> I'd like to use jquery to trim it down when someone hits a button to chop, but I'm having trouble doing it without overloading the browser. Assume I know that the character numbers are at 16,510 - 17,888, and what I'd like to do is trim it. I was using: jQuery('#textsection').html(jQuery('textarea').html().substr(range.start)); But browsers seem to enjoy crashing when I do this. Alternatives?

  • List<object>.RemoveAll - How to create an appropriate Predicate

    - by CJM
    This is a bit of noob question - I'm still fairly new to C# and generics and completely new to predicates, delegates and lamda expressions... I have a class 'Enquiries' which contains a generic list of another class called 'Vehicles'. I'm building up the code to add/edit/delete Vehicles from the parent Enquiry. And at the moment, I'm specifically looking at deletions. From what I've read so far, it appears that I can use Vehicles.RemoveAll() to delete an item with a particular VehicleID or all items with a particular EnquiryID. My problem is understanding how to feed .RemoveAll the right predicate - the examples I have seen are too simplistic (or perhaps I am too simplistic given my lack of knowledge of predicates, delegates and lambda expressions). So if I had a List<Of Vehicle> Vehicles where each Vehicle had an EnquiryID, how would I use Vehicles.RemoveAll() to remove all vehicles for a given EnquiryID? I understand there are several approaches to this so I'd be keen to hear the differences between approaches - as much as I need to get something working, this is also a learning exercise. As an supplementary question, is a Generic list the best repository for these objects? My first inclination was towards a Collection, but it appears I am out of date. Certainly Generics seem to be preferred, but I'm curious as to other alternatives. Thanks
