• Complex class using PHP soapserver mapclass

  - by user559343

  Hi all, I need to create a server for processing SOAP requests. I have the wsdl and xml specifications, but I have a doubt: the xml elements are pretty complex, they are not simple type, but they have parent/child relationships (e.g. I have a Book class with an author subclass). How can I map this to PHP classes? In this example, should I create an author class i.e.: class Author { public $name; public $surname; } and then class Book { public $author; } will $author be a class of type Author? Or a typed array? Any help will be appreciated Thanks and happy new year!

• Keeping a window always on top -- including menus (win32)

  - by Steven Lu

  I would like to have a layered window that is always-on-top, which I can accomplish, but there are certain screen elements that still get drawn over it, such as menus (including the start menu). Is there any way to make a window or child window of my application have a high enough top-ness property that it will draw over another application's menus? Or is there something built in to windows that ensures that menus in the currently active application are always drawn on top? In fact, I don't really understand all that well how menus work. So it might not even make any sense for me to try to make my window "act like a menu" in hopes of making it cover more things.

• correct technical term for this pattern

  - by Oliver A.

  sometimes I use a pattern which is very similar to the singleton pattern: There is one default instance which and a static get method to aces it. But you may create other instances and pass it as optional parameter and if you want to and you can even replace the default instance with a instance from a child class. So it is NO SINGLETON at all but it is used like one singleton in most cases. Anyone got an idea who to call something like this ? Maybe half*** singleton? domiton?

• How to find selected node in Tree?

  - by badgirl

  Hello. I have dynamic tree (moreover nodes can have children). Every node has some action. When I right click on some node, it offers me some actions. One action, for example createChildNode creates child node, which in turn creates MyObject2. MyObject2 must be created with assistance of MyOject1, which was created in parent node(that one where I right click for actions ). How to get that object from selected node? That objects in nodes are putted to lookups.singleton(MyObjectX)

• How do I declare a C# Web User Control but stop it from initializing?

  - by Scott Stafford

  I have a C#/ASP.NET .aspx page that declares two controls that each represents the content of one tab. I want a query string argument (e.g., ?tab=1) to determine which of the two controls is activated. My problem is, they both go through the initialization events and populate their child controls, wasting CPU resources and slowing the response time. Is it possible to deactivate them somehow so they don't go through any initialization? My .aspx page looks like this: <% if (TabId == 0) { %> <my:usercontroltabone id="ctrl1" runat="server" /> <% } else if (TabId == 1) { %> <my:usercontroltabtwo id="ctrl2" runat="server" /> <% } %> And that part works fine. I assumed the that <%'s would have meant the control wouldn't actually be declared and so wouldn't initialize, but that isn't so...

• Core Data-Linking one-to-many relationships

  - by Stelmate

  I have a one-to-many relationship where each department has many employees. When I create a new employee object I just link it to the parent department manually by setting the property to the instance of the department I have fetched from my fetch request. However, this seems to be improper because when I try to access the set of employees from the department by simply accessing the .employees property on my department object instance it returns a 0 count. Isn't the fault suppose to fire once I access a property? Am I linking my parent/child objects incorrectly?

• Retrieving Gtk::Widget's relative position: get_allocate() doesn't work

  - by a-v

  I need to retrieve the position of a Gtk::Widget relative to its parent, a Gtk::Table. Most sources (e.g. http://library.gnome.org/devel/gtk-faq/stable/x642.html) say that one needs to call Gtk::Widget::get_allocation(). However, the returned Gtk::Allocation object always contains x = -1, y = -1, width = 1, height = 1. I have to note that this happens before the Gtk::Table object is actually exposed and rendered. A call to show_all_children() or check_resize(), which I would expect to recalculate child widget geometry, doesn't help. What am I doing wrong? Thanks in advance.

• Find node level in a tree

  - by Álvaro G. Vicario

  I have a tree (nested categories) stored as follows: CREATE TABLE `category` ( `category_id` int(10) unsigned NOT NULL AUTO_INCREMENT, `category_name` varchar(100) NOT NULL, `parent_id` int(10) unsigned DEFAULT NULL, PRIMARY KEY (`category_id`), UNIQUE KEY `category_name_UNIQUE` (`category_name`,`parent_id`), KEY `fk_category_category1` (`parent_id`,`category_id`), CONSTRAINT `fk_category_category1` FOREIGN KEY (`parent_id`) REFERENCES `category` (`category_id`) ON DELETE SET NULL ON UPDATE CASCADE ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_spanish_ci I need to feed my client-side language (PHP) with node information (child+parent) so it can build the tree in memory. I can tweak my PHP code but I think the operation would be way simpler if I could just retrieve the rows in such an order that all parents come before their children. I could do that if I knew the level for each node: SELECT category_id, category_name, parent_id FROM category ORDER BY level -- No `level` column so far :( Can you think of a way (view, stored routine or whatever...) to calculate the node level? I guess it's okay if it's not real-time and I need to recalculate it on node modification.

• writing structs and classes to disk

  - by Phenom

  The following function writes a struct to a file. int btwrite(short rrn, BTPAGE *page_ptr) { long addr; addr = (long) rrn * (long) PAGESIZE + HEADERSIZE; lseek(btfd, addr, 0); return (write(btfd, page_ptr, PAGESIZE)); } The following is the struct. typedef struct { short keycount; /* number of keys in page */ int key[MAXKEYS]; /* the actual keys */ int value[MAXKEYS]; /* the actual values */ short child[MAXKEYS+1]; /* ptrs to rrns of descendants */ } BTPAGE; What would happen if I changed the struct to a class, would it still work the same? If I added class functions, would the size it takes up on disk increase?

• Using non-Railsy route to prepopulate a form

  - by user94154

  I have many instances of a Rails model, Post. When viewing an individual post, I'd like to create a form to create a child of Post called Comment. I'd like to prepopulate this form with a hidden tag that contains the post_id which is the foreign key in Comment. The Railsy way to do this is to create a fancy-ish route such as: /comments/new/post/:post_id However, this gunks up the routes file and doesn't leave much flexibility. Let's say I want to create a link somewhere else that prepopulates a different attribute of the form...then I'd have to add another route for this. So I think I'm going to create urls like this on /posts/show/:id: /comments/new?comment[post_id]=<%= @post.id %> This way I can add any other attributes as I need. I know the plus side associated with this, now what are the downsides?

• Sort objects and polymorphism

  - by ritmbo

  Suppose I have a class A. And B and C are child of A. Class A has a generic algorithm for sorting arrays of type A, so that I could use it for B and C without writing again the algorithm for each. In the algorithm, sometimes I have to swap. The problem is that I can only see the objects as type A, and if I do: A aux = array[i] array[i] = array[j] array[j] = aux I think I have a problem. Because array[i], maybe its of type B, and aux is of type A, so I think I'm losing information. I'm sure u understand this situation... how can I sort a generic array of objects using a father method algorithm?

• JQuery div tag has children in FireFox but not Chrome

  - by John Edwards

  I am using JQuery ajax to load images from a url, display them, and then place a button on top of each image. The code works in firefox, but in chrome, the div parent "photos" that should have all the children(one child div "photo" for each image received from the url) is 0. I have tried read() and load(), but nothing seems to work. If I run alert($('#photos').children().size()); in the Chrome console it returns the children. But at execution it returns 0. Any ideas? $(window).load(function () { $("p").text("The DOM is now loaded and can be manipulated."); //returns 0 in chrome, but 10 in firefox alert($('#photos').children().size()); $('#photos').children().each(function() { //do stuff

• linq with Include and criteria

  - by JMarsch

  How would I translate this into LINQ? Say I have A parent table (Say, customers), and child (addresses). I want to return all of the Parents who have addresses in California, and just the california address. (but I want to do it in LINQ and get an object graph of Entity objects) Here's the old fashioned way: SELECT c.blah, a.blah FROM Customer c INNER JOIN Address a on c.CustomerId = a.CustomerId where a.State = 'CA' The problem I'm having with LINQ is that i need an object graph of concrete Entity types (and it can't be lazy loaded. Here's what I've tried so far: // this one doesn't filter the addresses -- I get the right customers, but I get all of their addresses, and not just the CA address object. from c in Customer.Include(c = c.Addresses) where c.Addresses.Any(a = a.State == "CA") select c // this one seems to work, but the Addresses collection on Customers is always null from c in Customer.Include(c = c.Addresses) from a in c.Addresses where a.State == "CA" select c; Any ideas?

• copy an identity column into another table

  - by slake

  I have 2 tables that are related,both have identity columns for primary keys and i am using a vb form to insert data into them,My problem is that i cannot get the child table to get the primary key of the parent table and use this as its foreign key in my database. the data is inserted fine though no foreign key constraint is made.I am wondering if a trigger will do it and if so how. All my inserting of data is done in vb. The user wont insert any keys. all these are identity columns that are auto generated. If a trigger is my way out please illustrate with an example. If there is another way i can do this in VB itself then please advise and an example will be greatly appreciated Thanks in advance

• avoid caching of page in browser

  - by Shan

  I am using an iframe to show the child pages.In that one one particular page contains hidden div and i am showing it as a pop-up like thing with javascript by changing the visibility of the hidden div. Problem is before showing the hidden div , some manipulations are done at server level and I am calling the div from C# code after the manipulations like Page.ClientScript.RegisterStartupScript(GetType(), "MyKey", "javascript:OpenModelPopup('cb','cs');", true); so the page is getting posted back and the div is shown. after this, after going to next page if i click browser back it shows that page with that hidden div and on next click of browser back gives the page without hidden div. but I want to show only the initial stage of the page ie. without showing the hidden div that stage with hidden div should not be cached or it should not be shown on click of browser back.

• Abstract class get parameter from implementing subclass?

  - by soren.qvist

  I'm wondering if there is way to do this without breaking encapsulation, I want the abstract class to rely on parameters defined in the implementing subclass. Like so: public abstract class Parent { private int size; private List<String> someList; public Parent() { size = getSize(); someList = new ArrayList<String>(size); } public abstract int getSize(); } public class Child extends Parent { @Override public int getSize() { return 5; } } Is this ugly? Is there a better way? And perhaps more importantly, is this even a good idea?

• Resizing Ubuntu x64 Server Partition with VirtualBox not reflected in OS

  - by daleyjem

  I've already resized my virtual disk with VirtualBox, but now need to extend the partition of my Ubuntu VM itself. I thought I was on my way with GParted live CD, but after I resize the "extended" filesystem partition, and then the child "lvm2 pv" filesystem partition to fill the unallocated space, df -h still shows the original disk size after I reboot into the VM. Any tips on this? I've scoured the webs tirelessly. Should I be resizing the boot (/dev/sda1) partition instead? Should I try to convert my lvm2 to ext4 or something? I'm lost on this. Note: VirtualBox hard disk is "dynamic". Specs: VBox 4.2.18 Ubuntu 12.04.2 amd64 Gparted 0.16.2-1b-i486

• How can I simulate a click event via script?

  - by Scott B

  I have a jquery accordion style menu that I'd like to add some shortcut links to across the top. When one of these shortcuts is clicked, it should have the same effect as if the user clicked the corresponding a tag that serves as that panel's header... Here's some code... <div> Application Shortcuts > <a href="" onclick="simulateAclick("generalSettings")>Open General Settings</a> </div> <ul class="menu collapsible"> <li class='header'><a href='#' id="generalSettings">General Settings</a> <ul class='acitem'>...stuff goes here... In the example above, clicking on "Open General Settings" toggles the "acitem" UL's child elements visible. I'd just like to simulate a click on that element, from a link at the top of my app...

• How can specific the layout_width and layout_height of a Framelayout which fits an image

  - by michael

  Hi, I have an image which is 80px X 50 px, and I need to place that in one of the child of a FrameLayout, how can I specific the layout_width and layout_height of a Framelayout which fits an image without scaling it? I know there is a layout_height="wrap_content" layout_wight="wrap_content" for FrameLayout, but I can't use it, since that FrameLayout has other children. So I would like to hard code the FrameLayout width/height to match the dimension of the image? Should I use layout_width="80px" or layout_width="80dip"? Thank you.
