  • Search for nodes by name in XmlDocument

    - by RajenK
    I'm trying to find a node by name in an XmlDocument with the following code: private XmlNode FindNode(XmlNodeList list, string nodeName) { if (list.Count > 0) { foreach (XmlNode node in list) { if (node.Name.Equals(nodeName)) return node; if (node.HasChildNodes) FindNode(node.ChildNodes, nodeName); } } return null; } I call the function with: FindNode(xmlDocument.ChildNodes, "somestring"); For some reason it always returns null and I'm not really sure why. Can someone help me out with this?

  • How to detect if breaking an edge will make a graph disjoint?

    - by the_graph_guy
    I have a graph that starts off with a single, root node. Nodes are added one by one to the graph. At node creation time, they have to be linked either to the root node, or to another node, by a single edge. Edges can also be created and deleted (one by one, between any two nodes). Nodes can be deleted one at a time. Node and edge creation, deletion operations can happen in any arbitrary order. OK, so here's my question: When an edge is deleted, is it possible do determine, in constant time (i.e. with an O(1) algorithm), if doing this will divide the graph into two disjoint subgraphs? If it will, then which side of the edge will the root node belong? I'm willing to maintain, within reasonable limits, any additional data structure that can facilitate the derivation of this information. Maybe it is not possible to do it in O(1), if so any pointers to literature will be appreciated.

  • [Ext.tree.TreePanel] getNodeById does not work

    - by Moon
    Hi, I have a ext treepanel with json. var tree = new Ext.tree.TreePanel({ renderTo:'tree-container', title: 'Category', height: 300, width: 400, useArrows:true, autoScroll:true, animate:true, enableDD:true, containerScroll: true, rootVisible: false, frame: true, root: { text: 'Category', draggable: false, id: '0' }, // auto create TreeLoader dataUrl: $("#web").val() + "/category/index/get-nodes", listeners: { 'checkchange': function(node, checked){ if(checked){ categoryManager.add(node.id); //node.getUI().addClass('complete'); }else{ categoryManager.remove(node.id); // node.getUI().removeClass('complete'); } } } }); dataUrl loads the following json code [{"text":"Code Snippet","id":"1","cls":"folder","checked":false,"children":[{"text":"PHP","id":"3","cls":"file","checked":false,"children":[]},{"text":"Javascript","id":"4","cls":"file","checked":false,"children":[]}]}] when I try to find a node by console.log( tree.getNodeByid(3) ), it shows that it is undefined. Do I have a problem with my code?

  • How can I declare a pointer structure using {}?

    - by Y_Y
    This probably is one of the easiest question ever in C programming language... I have the following code: typedef struct node { int data; struct node * after; struct node * before; }node; struct node head = {10,&head,&head}; Is there a way I can make head to be *head [make it a pointer] and still have the availability to use '{ }' [{10,&head,&head}] to declare an instance of head and still leave it out in the global scope? For example: //not legal!!! struct node *head = {10,&head,&head};

  • How do I manipulate a tree of immutable objects?

    - by Frederik
    I'm building an entire application out of immutable objects so that multi-threading and undo become easier to implement. I'm using the Google Collections Library which provides immutable versions of Map, List, and Set. My application model looks like a tree: Scene is a top-level object that contains a reference to a root Node. Each Node can contain child Nodes and Ports. An object graph might look like this: Scene | +-- Node | +-- Node | +- Port +-- Node | +- Port +- Port If all of these objects are immutable, controlled by a top-level SceneController object: What is the best way to construct this hierarchy? How would I replace an object that is arbitrarily deep in the object tree? Is there a way to support back-links, e.g. a Node having a "parent" attribute?

  • Last element not getting insert in Tree

    - by rdk1992
    So I was asked to make a Binary Tree in Haskell taking as input a list of Integers. Below is my code. My problem is that the last element of the list is not getting inserted in the Tree. For example [1,2,3,4] it only inserts to the tree until "3" and 4 is not inserted in the Tree. data ArbolBinario a = Node a (ArbolBinario a) (ArbolBinario a) | EmptyNode deriving(Show) insert(x) EmptyNode= insert(tail x) (Node (head x) EmptyNode EmptyNode) insert(x) (Node e izq der) |x == [] = EmptyNode --I added this line to fix the Prelude.Head Empty List error, after I added this line the last element started to be ignored and not inserted in the tree |head x == e = (Node e izq der) |head x < e = (Node e (insert x izq) der) |head x > e = (Node e izq (insert x der)) Any ideas on whats going on here? Help is much appreciated

  • Need help in filtering the data with various condition and filling in scroll window GP

    - by Rahul
    Hi all, I am filtering the data and displaying in scroll window. There are many combination to display this data by customer id, customer id and itemnumber, customer id, itemnumber, work and history condition. And from date and To date condition. My query is when I am selecting the customer id and work or history table it should display the corresponding data. Like select * from price history where customerid=’custid’ and name=’Work’. It should display in scroll only these values none other it the same way history condition should work. Work and History are in check box. In my case whatever range I am selecting whether Work and History always loading with entire data, so it’s not filtering properly. My second problem is if I select from date and keep empty to date …in this case all the data should display from selected from date to end of table data. But I am not getting….pls somebody help me here is my entire coding: if empty('Customer Number') then warning "Select Customer ID"; focus 'Customer Number'; abort script; end if; if '(L) RadioGroup4' of window Window1 of form 'Customer Pricing Inquiry'=1 then if empty(Date) then abort script;

  • Is it right that Strophe.addHandler reads only first node from response?

    - by markcial
    I'm starting to learn strophe library usage and when i use addHandler to parse response it seems to read only first node of xml response so when i receive a xml like that : <body xmlns='http://jabber.org/protocol/httpbind'> <presence xmlns='jabber:client' from='test2@localhost' to='test2@localhost' type='avaliable' id='5593:sendIQ'> <status/> </presence> <presence xmlns='jabber:client' from='test@localhost' to='test2@localhost' xml:lang='en'> <status /> </presence> <iq xmlns='jabber:client' from='test2@localhost' to='test2@localhost' type='result'> <query xmlns='jabber:iq:roster'> <item subscription='both' name='test' jid='test@localhost'> <group>test group</group> </item> </query> </iq> </body> With the handler testHandler used like that : connection.addHandler(testHandler,null,"presence"); function testHandler(stanza){ console.log(stanza); } It only logs : <presence xmlns='jabber:client' from='test2@localhost' to='test2@localhost' type='avaliable' id='5593:sendIQ'> <status/> </presence> What i am missing? is it a right behaviour? Should i add more handlers to get the other stanzas? Thanks for advance

  • Node.js/Express Partials problem: Can't be nested too deep?

    - by heorling
    I'm learning Node.js, Express, haml.js and liking it. I've run into a prety annoying problem though. I'm pretty new to this but have been getting nice results so far. I'm writing a jquery heavy web app that relies on a table containing divs. The divs slide around, switch back and fourth and are resized etc to my hearts content. What I'm looking for a way to switch (template?) the divs. Since I've been building in express and mimicking the chat example it would make sense to use partials. The rub is that I've been using inexplicit divs in haml, held within a td. The divs are cunstructed as follows: %tr %td .class1.class2.class3.classetc Which has worked fine cross browser. Parsing the classes works great for the js code to pass arguments around, fetch values etc. What I'd like to be able to do is something like: %tr %td .class1.class2.class3.classetc %ul#messages != this.partial('message.html.haml', { collection: messages }) Any combination I've tried with this has failed however. And I might have tried them all. If I could put a partial into that div I'd probably be set. And you can nest them as long as you use #ids instead of .classes. But if you use more than one class it breaks! I think that's the most accurate way of summing it up. How do you do this? I've checked out various templating solutions like mu.js and micro template like by John Resig. I earlier checked out this thread on templating engines. It's very possible I'm making some fundamental mistake here, I'm new to this. What's a good way to do this?

  • Xpath query to select node when attribute does not exist? [closed]

    - by Antoine
    I want to select nodes for which a specific attribute does not exist. I've tried the Not() function, but it doesn't work. Is there a way for this? Example: The following Xpath query: group/msg[not(@owner)] Should retrieve the first node but not the 2nd one. However, both SketchPath (tool to test Xpath queries) and my C# code consider that the 2 nodes are ok. <group> <msg id="EVENTDATA_CCFLOADED_XMLCONTEXT" numericId="14026" translate="False" topicId="302" status="translated" > <text>Context</text> <comment></comment> </msg> <msg id="EVENTDATA_CCFLOADED_XMLCONTEXT_HELP" numericId="14027" translate="False" topicId="302" status="translated" owner="EVENTDATA_CCFLOADED_XMLCONTEXT" > <text>Provides the new data displayed in the Object.</text> <comment></comment> </msg> </group> In fact the Not() function works correctly, it's just that I had other conditions and parentheses weren't set correctly. errare humanum est.

  • What's right for me: htAccess, form submittion, HTTP header authentication w/ PHP?

    - by Brook Julias
    I am creating a website with multiple sections--admin, client, user, and anonymous--each user group having less access then the next. I am wondering what form of authentication would be best for my use? I have heard the if you are just dealing with a websites then a web form is for you (because it's prettier). HTTP header authentication with PHP is said to get clunky/sloppy. htAcess is pretty much the hard core of various authentication methods I have looked up, but is it too much?

  • How to check if user submit Arabic words from a form?

    - by ronanray
    Hi Experts.. Is there any reliable way to check if user has entered Arabic words into a form and tries to submit it? Can Javascript handle this? Or, only server script like .NET can do this? I'm thinking that if possible the script should directly prevent the user from inputting Arabic words into the form and show an alert pop up. Please share any examples if you have any idea how to do it. Thanks

    - by Tofig Hasanov
    I need my form in Delphi to be resizeable, and all components and controls should stretch proportionally, along with font sizes etc. Right now in order to resize components I write a code inside "OnResize" event, and manually calculate all components' sizes and fonts. I would like to have more simple solution, which I can apply to different applications without rewriting this code for each form. I found some components on the web, but they are shareware. Can you suggest something?

  • Array within Form collecting multiple values with the same name possible?

    - by JM4
    Good afternoon, I will first start with the goal I am trying to accomplish and then give a very basic sample of what I need to do. Goal Instead of collecting several variables and naming them with keys individually, I have decided to give in and use an array structure to handle all inputs of the same type and rules. Once I have the variables, I will validate against them and if 'ok' store them in a MySQL table. The table will hold consumer information and will need to store multiple rows of the same type of information. First Pass I will leave out the validation portion of this question because I feel I need to first understand the basics. <form action="?" method="POST" name="Form"> Member 1 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 1 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 1 Email: <input type="text" name="MemberEmail[]" /><br /> Member 2 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 2 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 2 Email: <input type="text" name="MemberEmail[]" /><br /> Member 3 First Name:<input type="text" name="MemberFirstName[]" /><br /> Member 3 Last Name: <input type="text" name="MemberLastName[]" /><br /> Member 3 Email: <input type="text" name="MemberEmail[]" /><br /> <input type="submit" name="submit" value="Continue" /> </form> I am hoping that each input given for First Name (a required field) will generate a unique key for that particular entry and not overwrite any data entered. Because I am carrying information from page to page (checkout form), I am turning the POST variables into SESSION variables then storing in a mysql database in the end. My hope is to have: <?php $conn = mysql_connect("localhost", "username", "password"); mysql_select_db("DBname",$conn); $sql = "INSERT INTO tablename VALUES ('$_SESSION[Member1FirstName]', '$_SESSION[Member1LastName]', '$_SESSION[Member1Email]', '$_SESSION[Member2FirstName]', '$_SESSION[Member2LastName]', '$_SESSION[Member2Email]', '$_SESSION[Member1FirstName]', '$_SESSION[Member3LastName]', '$_SESSION[Member3Email]')"; $result = mysql_query($sql, $conn) or die(mysql_error()); Header ("Location: completed.php"); ?> Where Member1, Member2, and Member3 values will appear on their own row within the table. I KNOW my code is wrong but I am giving a first shot at the overall business purpose I am trying to achieve and trying to learn how to code the right way. I am very, very new to programming so any 'baby advice' is greatly appreciated.

  • How to clear all form fields from code-behind?

    - by Slauma
    HTML has an input button type to reset all fields in a form to their initial state in one step: <input type="reset" ... />. Is there a similar simple way to reset all form fields of an aspx page from code-behind? Or is it necessary to reset all controls one by one with TextBox1.Text=string.Empty, TextBox2.Text=string.Empty, etc. ? Thanks in advance!

  • Can I have a user submit a form and receive a PDF copy?

    - by thatryan
    Not quite sure how to ask this :) But what I need is to have some forms online that people can fill out, like registration form etc. They will then submit it and be emailed it as well as me and have it stored in a database. Is there a way for the files to be PDFs? Can I have an editable PDF form online? Thank you.
