  • Why is my logic not working correctly for SPOJ TOPOSORT?

    - by Kavish Dwivedi
    The given problem is http://www.spoj.com/problems/TOPOSORT/ The output format is particularly important as : Print "Sandro fails." if Sandro cannot complete all his duties on the list. If there is a solution print the correct ordering, the jobs to be done separated by a whitespace. If there are multiple solutions print the one, whose first number is smallest, if there are still multiple solutions, print the one whose second number is smallest, and so on. What I am doing is simply doing dfs by reversing the edges i.e if job A finishes before job B, there is a directed edge from B to A . I am maintaining the order by sorting the adjacency list I created and storing the nodes which don't have any constraints separately so as to print them later in correct order . There are two flag arrays used , one for marking discovered node and one for marking the node whose all neighbors have been explored. Now my solution is http://www.ideone.com/QCUmKY (the important function is the visit funtion ) and its giving WA after running correct for 10 cases so its really hard to figure out where am I doing it wrong since it runs for all of the test cases which I have done by hand.

  • DIY intellisense on XPath - design approach? (WinForms app)

    - by Cheeso
    I read the DIY Intellisense article on code project, which was referenced from the Mimic Intellisense? question here on SO. I wanna do something similar, DIY intellisense, but for XPath not C#. The design approach used there makes sense to me: maintain a tree of terms, and when the "completion character" is pressed, in the case of C#, a dot, pop up the list of possible completions in a textfield. Then allow the user to select a term from the textfield either through typing, arrow keys, or double-click. How would you apply this to XPath autocompletion? should there be an autocomplete key? In XPath there is no obvious separator key like "dot" in C#. should the popup be triggered explicitly in some other way, let's say ctrl-. ? or should the parser try to autocomplete continuously? If I do the autocomplete continuously, how to scale it properly? There are 93 xpath functions, not counting overloads. I certainly don't want to popup a list of 93 choices. How do I decide when I've narrowed it enough to offer a useful lsit of possible completions? How to populate the tree of possible completions? For C#, it's easy: walk the type space via reflection. At a first level, the "syntax tree" for C# seems like a single tree, and the list of completions at any point depends on the graph of nodes you've traversed to that point. Typing System.Console. traverses to a certain node in that tree, and the list of completions is the set of child nodes available at that node in the tree. On the other hand, the xpath syntax seems like it is a "flatter" tree - function names, axis names, literals. Does this make sense? what have I not considered?

  • TCL TDom: Looping through Objects

    - by pws5068
    Using TDom, I would like to cycle through a list of objects in the following format: <object> <type>Hardware</type> <name>System Name</name> <description>Basic Description of System.</description> <attributes> <vendor>Dell</vendor> <contract>MM/DD/YY</contract> <supportExpiration>MM/DD/YY</supportExpiration> <location>Building 123</location> <serial>xxx-xxx-xxxx</serial> <mac>some-mac-address</mac> </attributes> </object> <object> <type>Software</type> <name>Second Object</name> ... Then I use TDom to make a list of objects: set dom [dom parse $xml] set doc [$dom documentElement] set nodeList [$doc selectNodes /systems/object] So far I've done this to (theoretically) select every "Object" node from the list. How can I loop through them? Is it just: foreach node $nodeList { For each object, I need to retrieve the association of each attribute. From the example, I need to remember that the "name" is "System Name", "vendor" is "Dell", etc. I'm new to TCL but in other languages I would use an object or an associative list to store these. Is this possible? Can you show me an example of the syntax to select an attribute in this manner?

  • asp.net, how to change text color to red in child nodes in VB codes?

    - by StudentIT
    I got everything worked now by list of server Name but I want to add a IF statement by checking a column from SQL Server called Compliance by either True or False value listed. If it False, the Name will change text color to Red. If it True, the Name won't change text color. I am not sure how add that in VB codes side.

  • Problem on "Finding cursor position" function

    - by sanceray3
    Hi all, Few days ago, I have found a solution to obtain the cursor position on a div with contentedit="true". I use the solution defined on this web site : Finding cursor position in a contenteditable div function getCursorPos() { var cursorPos; if (window.getSelection) { var selObj = window.getSelection(); var selRange = selObj.getRangeAt(0); cursorPos = findNode(selObj.anchorNode.parentNode.childNodes, selObj.anchorNode) + selObj.anchorOffset; /* FIXME the following works wrong in Opera when the document is longer than 32767 chars */ } else if (document.selection) { var range = document.selection.createRange(); var bookmark = range.getBookmark(); /* FIXME the following works wrong when the document is longer than 65535 chars */ cursorPos = bookmark.charCodeAt(2) - 11; /* Undocumented function [3] */ } return cursorPos; } function findNode(list, node) { for (var i = 0; i < list.length; i++) { if (list[i] == node) { return i; } } return -1; } It functions well, but when I use html tags inside the div the pointer doesnt show the correct position. For example if I try to find cursor position on the <strong>cat</strong> is black, the function doesn't return me the good position. But if I try on the cat is black, it functions. Any ideas how to get the position with html tags ? Thanks for your help.

  • Interactive Web Collaboration Platform

    - by user1477586
    I am currently unsatisfied with most, if not all, web-based collaboration tools I've ever used. Examples of what I'm considering a "web-based collaboration tool" are TWiki, WebEx, etc. What I have in mind of developing is to develop my own. The target "market" is for software/hardware developers who will likely be working on separate projects linked by a common goal. Example: You work at a company who is designing a brand new printer. So, one man is working on the ink cartridge, another on the paper feed, one on the circuitry of the printer and one more is working on the drivers. What I would like to make (unless it already exists) is a website that, upon loading, presents the user with a web that has each project within it's own bubble, graphically. These bubbles would all be linked to the central bubble of "[Company Name]". Upon selecting an individual bubble the browser would focus and zoom in on that project bubble and expand more information (in bullets or with more affiliated bubbles) about subprojects, progress, setbacks, etc. Then, at a terminal "node" (i.e. a bubble with no sub-bubbles) a selection would then load a page with information relevant to that node. That's a lot of monologue. In short, I want to know how I might approach this. My background is with algorithmic use of Python and C++. I've never done interactive web design like this; though, I have gone through the W3C tutorials on HTML4/5. I'm willing to learn a new language I'm just wondering which language/set of languages seem(s) most appropriate for this project. Thanks, world, for imparting your knowledge to me. An example of what the start page might look like is:

  • searching XML documents using php

    - by dbomb101
    I am trying to make a search function using the combination of DOM, PHP and XML. I got something up and running but the problem is that my search function will only accept exact terms, on top of this am wondering if the method I picked the most efficient $searchTerm = "Lupe"; $doc = new DOMDocument(); foreach (file('musicInformation.xml')as $node) { $xmlString .= trim($node); } $doc->loadXML($xmlString); $records = $doc->documentElement->childNodes; $records = $doc->getElementsByTagName("musicdetails"); foreach( $records as $record ) { $artistnames = $record->getElementsByTagName("artistname"); $artistname = $artistnames->item(0)->nodeValue; $recordnames = $record->getElementsByTagName("recordname"); $recordname = $recordnames->item(0)->nodeValue; $recordtypes = $record->getElementsByTagName("recrodtype"); $recordtype = $recordtypes->item(0)->nodeValue; $formats = $record->getElementsByTagName("format"); $format = $formats->item(0)->nodeValue; $prices = $record->getElementsByTagName("price"); $price = $prices->item(0)->nodeValue; if($searchTerm == $artistname|| $searchTerm == $recordname || $searchTerm == $recordtype ||$searchTerm == $format || $searchTerm == $price) { echo "$artistname - $recordname - $recordtype - $format -$price\n"; }

  • I'm having trouble with using std::stack to retrieve the values from a recursive function.

    - by Peter Stewart
    Thanks to the help I received in this post: http://stackoverflow.com/questions/2761918/how-do-i-use-this-in-a-member-function I have a nice, concise recursive function to traverse a tree in postfix order: void Node::postfix() { if (left != __nullptr) { left->postfix(); } if (right != __nullptr) { right->postfix(); } cout<<cargo<<"\n"; return; }; Now I need to evaluate the values and operators as they are returned. My problem is how to retrieve them. I tried the std::stack: #include <stack> stack <char*> s; void Node::postfix() { if (left != __nullptr) { left->postfix(); } if (right != __nullptr) { right->postfix(); } s.push(cargo); return; }; but when I tried to access it in main() while (!s.empty()) { cout<<s.top<<"\n"; s.pop; } I got the error: 'std::stack<_Ty::top': function call missing argument list; use '&std::stack<_Ty::top' to create a pointer to member' I'm stuck. Another question to follow shortly.

  • How to access CSS generated content with JavaScript

    - by Boldewyn
    I generate the numbering of my headers and figures with CSS's counter and content properties: img.figure:after { counter-increment: figure; content: "Fig. " counter(section) "." counter(figure); } This (appropriate browser assumed) gives a nice labelling "Fig. 1.1", "Fig. 1.2" and so on following any image. Question: How can I access this from Javascript? The question is twofold in that I'd like to access either the current value of a certain counter (at a certain DOM node) or the value of the CSS generated content (at a certain DOM node) or, obviously, both information. Background: I'd like to append to links back-referencing to figures the appropriate number, like this: <a href="#fig1">see here</h> ------------------------^ " (Fig 1.1)" inserted via JS As far as I can see, it boils down to this problem: I could access content or counter via getComputedStyle: var fig_content = window.getComputedStyle( document.getElementById('fig-a'), ':after').content; However, this is not the live value, but the one declared in the stylesheet. I cannot find any interface to access the real live value.

  • PHP: Recursive array function

    - by Industrial
    Hi everybody, I want to create a function that returns the full path from a set node, back to the root value. I tried to make a recursive function, but ran out of luck totally. What would be an appropriate way to do this? I assume that a recursive function is the only way? Here's the array: Array ( [0] => Array ( [id] => 1 [name] => Root category [_parent] => ) [1] => Array ( [id] => 2 [name] => Category 2 [_parent] => 1 ) [2] => Array ( [id] => 3 [name] => Category 3 [_parent] => 1 ) [3] => Array ( [id] => 4 [name] => Category 4 [_parent] => 3 ) ) The result I want my function to output when getting full path of node id#4: Array ( [0] => Array ( [id] => 1 [name] => Root category [_parent] => ) [1] => Array ( [id] => 3 [name] => Category 3 [_parent] => 1 ) [2] => Array ( [id] => 4 [name] => Category 4 [_parent] => 3 ) ) The notoriously bad example of my recursive skills: function recursive ($id, $array) { $innerarray = array(); foreach ($array as $k => $v) { if ($v['id'] === $id) { if ($v['_parent'] !== '') { $innerarray[] = $v; recursive($v['id'], $array); } } } return $innerarray; } Thanks!

  • How do you keep the text selection on a DataGridView?

    - by fneep
    I'm running C# 2.0, and I've written an application with a DataGridView in virtualmode and a TreeView in the same form, but in different panels of a SplitContainer. My application has a "find all" function that finds all instances of a certain string, and adds them as the child nodes to a new node to the TreeView (it's a tree view because you can have multiple search results by having different root nodes). That idea is that when you click on one of those search results in the TreeView, that it would select the specific text of that result in the DataGridView (Virtually the same as Notepad++'s find all function) When I click on the TreeView, it does set the selected cell of the DataGridView and highlight the specific text, but it loses that specific text selection instantly (but keeps the cell selection) because by clicking on the TreeView the DataGridView loses focus. Here's the code for the AfterSelect of the TreeView: private void Tree_Results_AfterSelect(object sender, TreeViewEventArgs e) { if (e.Node.Level > 0) { SearchResult SelectedItem = (SearchResult)Tree_Results.SelectedNode.Tag; DataViewMain.CurrentCell = DataViewMain[SelectedItem.TypeIndex, SelectedItem.LineIndex]; DataViewMain.BeginEdit(false); DataGridViewTextBoxEditingControl SelectionData = (DataGridViewTextBoxEditingControl)DataViewMain.EditingControl; SelectionData.SelectionStart = SelectedItem.HighlightStart; SelectionData.SelectionLength = SelectedItem.HightlightLength; } } If the DataGridView were a text box I could possibly set HideSelection to false, but DataGridViews have no such property (and changing the Hide Selection for the EditingControl does nothing) Any ideas? I'm receptive to a different control instead of a TreeView that would allow my DataGridView to retain focus.

  • PHP database simulation

    - by Emdiesse
    I have a PHP script that works by calling items from a database based upon the time they were placed in there and it deletes them if they are older than 5 minutes. Basically, I want to now simulate what would happen if this database was being updated regularly. So I was considering sticking in some code that loads an XML file then goes through and parses that into the database based upon the time data located within a node of the xml data... but the problem there is I want it to continually loop through an enter this data so it'll never actually run the other processes So I was thinking of having another PHP script do that that could do this independantly of the php script that is going to display this data... In theory: I am looking to have a button that I can press and it will then run some php code to load up an XML file from a directory on my web server and then iterate though the data sending the data, to a database, based upon the time within a node in the PHP script and when the script was first called So back to my page that displayed the data... if I continually hit refresh it will contain different results each time because data is being added by the other process and this php script removes the older data when it is refreshed Any information on this? Is there a way I can silently, and safely, run a php script without it being loaded into a browser... like a thread!?

  • addNotify not works allright

    - by joseph
    Hello. I call addNotify() method in class that I posted here. The problem is, that when I call addNotify() as it is in the code, setKeys(objs) do nothing. Nothing appears in my explorer of running app. But when I call addNotify()without loop(for int....), and add only one item to ArrayList, it shows that one item correctly. Does anybody knows where can be problem? See the cede class ProjectsNode extends Children.Keys{ private ArrayList objs = new ArrayList(); public ProjectsNode() { } @Override protected Node[] createNodes(Object o) { MainProject obj = (MainProject) o; AbstractNode result = new AbstractNode (new DiagramsNode(), Lookups.singleton(obj)); result.setDisplayName (obj.getName()); return new Node[] { result }; } @Override protected void addNotify() { //this loop causes nothing appears in my explorer. //but when I replace this loop by single line "objs.add(new MainProject("project1000"));", it shows that one item in explorer for (int i=0;i==10;i++){ objs.add(new MainProject("project1000")); } setKeys (objs); } }

  • Keeping the UI responsive while parsing a very large logfile

    - by Carlos
    I'm writing an app that parses a very large logfile, so that the user can see the contents in a treeview format. I've used a BackGroundWorker to read the file, and as it parses each message, I use a BeginInvoke to get the GUI thread to add a node to my treeview. Unfortunately, there's two issues: The treeview is unresponsive to clicks or scrolls while the file is being parsed. I would like users to be able to examine (ie expand) nodes while the file is parsing, so that they don't have to wait for the whole file to finish parsing. The treeview flickers each time a new node is added. Here's the code inside the form: private void btnChangeDir_Click(object sender, EventArgs e) { OpenFileDialog browser = new OpenFileDialog(); if (browser.ShowDialog() == DialogResult.OK) { tbSearchDir.Text = browser.FileName; BackgroundWorker bgw = new BackgroundWorker(); bgw.DoWork += (ob, evArgs) => ParseFile(tbSearchDir.Text); bgw.RunWorkerAsync(); } } private void ParseFile(string inputfile) { FileStream logFileStream = new FileStream(inputfile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); StreamReader LogsFile = new StreamReader(logFileStream); while (!LogsFile.EndOfStream) { string Msgtxt = LogsFile.ReadLine(); Message msg = new Message(Msgtxt.Substring(26)); //Reads the text into a class with appropriate members AddTreeViewNode(msg); } } private void AddTreeViewNode(Message msg) { TreeNode newNode = new TreeNode(msg.SeqNum); BeginInvoke(new Action(() => { treeView1.BeginUpdate(); treeView1.Nodes.Add(newNode); treeView1.EndUpdate(); Refresh(); } )); } What needs to be changed?

  • Drupal: Template Files, Modules and Content Types for Advanced Theme

    - by theandym
    Intro I am in the process of trying to convert my first HTML/CSS design into a theme for Drupal. I have used ModX for quite a few designs and appreciate the ability to create different page templates and custom variables to be assigned to those templates. However I seem to be having some issues making the transition. The site I am working on theming in Drupal is for a real estate agent. Each page/section will have a different set of content associated with it and will need to display only that content. For example, there will be a page for current listings, each of which will be formatted by a custom content type. However, when I call the content on the home page (or on other pages) I do not want to see this listing data. Layout The layout of the site and the regions associated with each page/section is as follows: Home Spotlight Featured 1 Featured 2 About Spotlight Bios - Profiles of each agent (each will be a node with name, contact info, pic, etc) listed on the page; multiple nodes listed Sidebar Listings Spotlight Listings - Profiles of properties (each will be a node with locations, basic info, pic, etc) listed on the page; multiple nodes listed Sidebar Services Spotlight Content - general paragraph text area Sidebar News/Blog News/Blog Items - List of stories with summaries and links to full article Sidebar Each page/section will use the same header and footer. Issue I have done some reading on Drupal, custom content types (and CCK), Views, and Pathauto. However I have not been able to get a clear picture of how to put it all together to accomplish what I am attempting. What I really would like to know is which modules to use, how best to use them, which elements I need to use where, and what template files I should be using to theme the elements I need to use. Any help or reference to useful resources would be much appreciated.

  • Returning recursive ternary freaks out

    - by David Titarenco
    Hi, assume this following function: int binaryTree::findHeight(node *n) { if (n == NULL) { return 0; } else { return 1 + max(findHeight(n->left), findHeight(n->right)); } } Pretty standard recursive treeHeight function for a given binary search tree binaryTree. Now, I was helping a friend (he's taking an algorithms course), and I ran into some weird issue with this function that I couldn't 100% explain to him. With max being defined as max(a,b) ((a)>(b)?(a):(b)) (which happens to be the max definition in windef.h), the recursive function freaks out (it runs something like n^n times where n is the tree height). This obviously makes checking the height of a tree with 3000 elements take very, very long. However, if max is defined via templating, like std does it, everything is okay. So using std::max fixed his problem. I just want to know why. Also, why does the countLeaves function work fine, using the same programmatic recursion? int binaryTree::countLeaves(node *n) { if (n == NULL) { return 0; } else if (n->left == NULL && n->right == NULL) { return 1; } else { return countLeaves(n->left) + countLeaves(n->right); } } Is it because in returning the ternary function, the values a => countLeaves(n->left) and b => countLeaves(n->right) were recursively double called simply because they were the resultants? Thank you!

  • Validating textboxes and checkboxes then add the values of those checkboxes

    - by TiTi Nguyen
    I am very new to Javascript. I am running to a problem and don't know how to solve it. Could you please help? Basically, I want to create some textboxes and checkboxes in a form. Then I have to validate those fields, and add the values of the checkboxes if they are selected. One of the textboxes asking for how many semesters attended, and 3 checkboxes with value of 100, 1000, and 750. Whichever checkbox is selected, it should multiply its value to the number of semesters attended. For example if the first two checkboxes are selected then totalCost = (100+1000)* semester. Here is my code: User Name: <label>User Address: <input type = "text" id ="address" size = "30"/></label> <br/><br/> <label> User E-mail address: <input type = "text" id ="email" size = "30"/></label> <br/><br/> <label> User Phone number: <input type = "text" id ="phone" size = "30"/></label> <br/><br/> <label> User area code: <input type = "text" id ="area" size = "30"/></label> <br/><br/> <label> User SSN: <input type = "text" id ="ssn" size = "30"/></label> <br/><br/> <label> User Birthday: <input type = "text" id ="birthday" size = "30"/></label> <br/><br/> <label> Number of semester attended: <input type = "text" id ="semester" size = "3"/></label> <br/><br/> <label><input type="checkbox" id="box_book" value="100"/>Books $100 per semester</label> <br/> <label><input type="checkbox" id="box_tuition" value="1000"/>Tuition $1000 per semester</label> <br/> <label><input type="checkbox" id="box_room" value="750"/>Room and Board $750 per semester</label> <br/> <input type="reset" id="reset"/> <input type="submit" id="submit" onclick="checking()"/> <p/> </form> function checking() { var name=document.forms["myForm"]["name"].value; var address=document.forms["myForm"]["address"].value; var email=document.forms["myForm"]["email"].value; var atpos=email.indexOf("@"); var dotpos=email.lastIndexOf("."); var phone=document.forms["myForm"]["phone"].value; var area=document.forms["myForm"]["area"].value; var ssn=document.forms["myForm"]["ssn"].value; var birth=document.forms["myForm"]["birthday"].value; var semester=document.forms["myForm"]["semester"].value; var boxBook = document.forms["myForm"]["box_book"].value; var boxTuition = document.forms["myForm"]["box_tuition"].value; var boxRoom = document.forms["myForm"]["box_room"].value; if (name==null || name=="") { alert("Please fill in your name."); return false; } if (address==null || address=="") { alert("Please fill in your address."); return false; } if (atpos<1 || dotpos<atpos+2 || dotpos+2>=email.length) { alert("The email (" + email + ") is not a valid e-mail address.

Please help.

  • How can I write System preferences with Java? Can I invoke UAC?

    - by Jonas
    How can I write system preferences with Java, using Preferences.systemRoot()? I tried with: Preferences preferences = Preferences.systemRoot(); preferences.put("/myapplication/databasepath", pathToDatabase); But I got this error message: 2010-maj-29 19:02:50 java.util.prefs.WindowsPreferences openKey VARNING: Could not open windows registry node Software\JavaSoft\Prefs at root 0x80000002. Windows RegOpenKey(...) returned error code 5. Exception in thread "AWT-EventQueue-0" java.lang.SecurityException: Could not open windows registry node Software\JavaSoft\Prefs at root 0x80000002: Access denied at java.util.prefs.WindowsPreferences.openKey(Unknown Source) at java.util.prefs.WindowsPreferences.openKey(Unknown Source) at java.util.prefs.WindowsPreferences.openKey(Unknown Source) at java.util.prefs.WindowsPreferences.putSpi(Unknown Source) at java.util.prefs.AbstractPreferences.put(Unknown Source) at biz.accountia.pos.install.Setup$2.actionPerformed(Setup.java:43) I would like to do this, because I want to install an embedded JavaDB database, and let multiple users on the computer to use the same database with the application. How to solve this? Can I invoke UAC and do this as Administrator from Java? And if I log in as Administrator when writing, can I read the values with my Java application if I'm logged in as a User?

  • How to hide some nodes in Richfaces Tree (do not render nodes by condition)?

    - by VestniK
    I have a tree of categories and courses in my SEAM application. Courses may be active and inactive. I want to be able to show only active or all courses in my tree. I've decided to always build complete tree in my PAGE scope component since building this tree is quite expensive operation. I have boolean flag courseActive in the data wrapped by TreeNode<T>. Now I can't find the way to show courses node only if this flag is true. The best result I've achieved with the following code: <h:outputLabel for="showInactiveCheckbox" value="show all courses: "/> <h:selectBooleanCheckbox id="showInactiveCheckbox" value="#{categoryTreeEditorModel.showAllCoursesInTree}"> <a4j:support event="onchange" reRender="categoryTree"/> </h:selectBooleanCheckbox> <rich:tree id="categoryTree" value="#{categoryTree}" var="item" switchType="ajax" ajaxSubmitSelection="true" reRender="categoryTree,controls" adviseNodeOpened="#{categoryTreeActions.adviseRootOpened}" nodeSelectListener="#{categoryTreeActions.processSelection}" nodeFace="#{item.typeName}"> <rich:treeNode type="Category" icon="..." iconLeaf="..."> <h:outputText value="#{item.title}"/> </rich:treeNode> <rich:treeNode type="Course" icon="..." iconLeaf="..." rendered="#{item.courseActive or categoryTreeEditorModel.showAllCoursesInTree}"> <h:outputText rendered="#{item.courseActive}" value="#{item.title}"/> <h:outputText rendered="#{not item.courseActive}" value="#{item.title}" style="color:#{a4jSkin.inactiveTextColor}"/> </rich:treeNode> </rich:tree> the only problem is if some node is not listed in any rich:treeNode it just still shown with title obtained by Object.toString() method insted of being hidden. Does anybody know how to not show some nodes in the Richfases tree according to some condition?

  • passing values between forms (winforms)

    - by dnkira
    Hello. Vierd behaviar when passing values to and from 2nd form. ParameterForm pf = new ParameterForm(testString); works ParameterForm pf = new ParameterForm(); pf.testString="test"; doesn't (testString defined as public string) maybe i'm missing something? anyway i'd like to make 2nd variant work properly, as for now - it returns null object reference error. thanks for help. posting more code here: calling Button ParametersButton = new Button(); ParametersButton.Click += delegate { ParameterForm pf = new ParameterForm(doc.GetElementById(ParametersButton.Tag.ToString())); pf.ShowDialog(this); pf.test = "test"; pf.Submit += new ParameterForm.ParameterSubmitResult(pf_Submit); }; definition and use public partial class ParameterForm : Form { public string test; public XmlElement node; public delegate void ParameterSubmitResult(object sender, XmlElement e); public event ParameterSubmitResult Submit; public void SubmitButton_Click(object sender, EventArgs e) { Submit(this,this.node); Debug.WriteLine(test); } } result: Submit - null object reference test - null object reference

  • Populate textboxes with XmlNode.Attributes

    - by Doug
    I have Data.xml: <?xml version="1.0" encoding="utf-8" ?> <data> <album> <slide title="Autum Leaves" description="Leaves from the fall of 1986" source="images/Autumn Leaves.jpg" thumbnail="images/Autumn Leaves_thumb.jpg" /> <slide title="Creek" description="Creek in Alaska" source="images/Creek.jpg" thumbnail="images/Creek_thumb.jpg" /> </album> </data> I'd like to be able to edit the attributes of each Slide node via GridView (that has a "Select" column added.) And so far I have: protected void GridView1_SelectedIndexChanged(object sender, EventArgs e) { int selectedIndex = GridView1.SelectedIndex; LoadXmlData(selectedIndex); } private void LoadXmlData(int selectedIndex) { XmlDocument xmldoc = new XmlDocument(); xmldoc.Load(MapPath(@"..\photo_gallery\Data.xml")); XmlNodeList nodelist = xmldoc.DocumentElement.ChildNodes; XmlNode xmlnode = nodelist.Item(selectedIndex); titleTextBox.Text = xmlnode.Attributes["title"].InnerText; descriptionTextBox.Text = xmlnode.Attributes["description"].InnerText; sourceTextBox.Text = xmlnode.Attributes["source"].InnerText; thumbTextBox.Text = xmlnode.Attributes["thumbnail"].InnerText; } The code for LoadXmlData is just a guess on my part - I'm new to working with xml in this way. I'd like have the user to slected the row from the gridview, then populate a set of text boxes with each slide attributed for updating back to the Data.xml file. The error I'm getting is Object reference not set to an instance of an object" at the line: titleTextBox.Text = xmlnode.Attributes["@title"].InnerText; so I'm not reaching the attribute "title" of the slide node. Thanks for any ideas you may have.

  • converting a Tree to newick format. java

    - by Esmond
    I'm having problems converting a binary rooted tree to newick format. The full explanation for such a format can be found: http://code.google.com/p/mrsrf/wiki/NewickTree An example of a newick format would be as follows: for a tree T such as http://www.cs.mcgill.ca/~cs251/OldCourses/1997/topic8/images/completetreetwo.gif the newick representation would be: (((8,9),(10,11)),((12,13),(14,15))) the internal node will become the commas while the leaves will be retained. such trees have internal nodes which will always have 2 children. I have a problem using recursion to come out with this newick format. The output contains far too many nodes and braces. Any comments to resolve this problem is appreciated or even an iterative algorithm would be welcomed import java.util.Stack; public class Tree { .... public String inOrderNewick(Node root, String output) throws ItemNotFoundException { if (root.hasChild()) { output += "("; output += inOrderNewick(root.child1, output); output += ","; output += inOrderNewick(root.child2, output); output += ")"; return output; } else { output += root.getSeq(); return output; } } }

  • Select list auto update on any kind of change?

    - by Tom Irons
    I have a jQuery that when you click on a select option it will show the next one, but you have to click, you cant just use the down arrow or "tab" to the next option. I am wondering what options do I have to make this work? Here is my jQuery: function typefunction() { var itemTypes = jQuery('#type'); var select = this.value; itemTypes.change(function () { if ($(this).val() == '1-Hand') { $('.1-Hand').show(); $('.2-Hand').hide(); $('.off').hide(); $('.Armor').hide(); } else $('.1-Hand').hide(); if ($(this).val() == '2-Hand') { $('.2-Hand').show(); $('.1-Hand').hide(); $('.off').hide(); $('.Armor').hide(); } else $('.2-Hand').hide(); if ($(this).val() == 'Armor') { $('.Armor').show(); $('.2-Hand').hide(); $('.off').hide(); $('.1-Hand').hide(); } else $('.Armor').hide(); if ($(this).val() == 'Off-Hand') { $('.Off').show(); $('.2-Hand').hide(); $('.1-Hand').hide(); $('.Armor').hide(); } else $('.Off').hide(); if ($(this).val() == '1-Hand') { $('.one-hand-dps').show(); $('.item-armor').hide(); $('.two-hand-dps').hide(); } else $('.one-hand-dps').hide(); if ($(this).val() == '2-Hand') { $('.two-hand-dps').show(); $('.one-hand-dps').hide(); $('.item-armor').hide(); } else $('.two-hand-dps').hide(); if ($(this).val() == 'Armor') { $('.item-armor').show(); $('.one-hand-dps').hide(); $('.two-hand-dps').hide(); } else $('.item-armor').hide(); }); } And the HTML: <div class="input-group item"> <span class="input-group-addon">Type</span> <select id="type" name="type" class="form-control" onclick="typefunction(); itemstats(); Armor(); OffHand(); TwoHand();"> <option value="Any Type">Any Type</option> <option value="1-Hand">1-Hand</option> <option value="2-Hand">2-Hand</option> <option value="Armor">Armor</option> <option value="Off-Hand">Off-Hand</option> </select> </div> <div class="input-group item"> <span class="1-Hand input-group-addon" style="display: none;">Sub-Type</span> <select class="1-Hand form-control" name="sub[1]" style="display: none;"> <option value="All 1-Hand Item Types">All 1-Hand Item Types</option> <option>Axe</option> <option>Ceremonial Knife</option> <option>Hand Crossbow</option> <option>Dagger</option> <option>Fist Weapon</option> <option>Mace</option> <option>Mighty Weapon</option> <option>Spear</option> <option>Sword</option> <option>Wand</option> </select> </div> <div class="input-group"> <span class="2-Hand input-group-addon" style="display: none; ">Sub-Type</span> <select class="2-Hand form-control" name="sub[2]" style="display: none;"> <option>All 2-Hand Item Types</option> <option>Two-Handed Axe</option> <option>Bow</option> <option>Diabo</option> <option>Crossbow</option> <option>Two-Handed Mace</option> <option>Two-Handed Mighty Weapon</option> <option>Polearm</option> <option>Staff</option> <option>Two-Handed Sword</option> </select> </div> <div class="input-group"> <span class="Armor input-group-addon" style="display: none;">Sub-Type</span> <select class="Armor form-control" name="sub[3]" style="display:none;"> <option>All Armor Item Types</option> <option>Amulet</option> <option>Belt</option> <option>Boots</option> <option>Bracers</option> <option>Chest Armor</option> <option>Cloak</option> <option>Gloves</option> <option>Helm</option> <option>Pants</option> <option>Mighty Belt</option> <option>Ring</option> <option>Shoulders</option> <option>Spirit Stone</option> <option>Voodoo Mask</option> <option>Wizard Hat</option> </select> </div> <div class="input-group"> <span class="Off input-group-addon" style="display: none;">Sub-Type</span> <select class="Off form-control" name="sub[4]" style="display:none;"> <option>All Off-Hand Item Types</option> <option>Mojo</option> <option>Source</option> <option>Quiver</option> <option>Shield</option> </select> </div>
