  • Is this a SEO SAFE anchor link

    - by Mayhem
    so... Is this a safe way to use internal links on your site.. By doing this i have the index page generating the usual php content section and handing it to the div element. THE MAIN QUESTION: Will google still index the pages using this method? Common sense tells me it does.. But just double checking and leaving this here as a base example as well if it is. As in. EXAMPLE ONLY PEOPLE The Server Side if (isset($_REQUEST['page'])) {$pageID=$_REQUEST['page'];} else {$pageID="home";} if (isset($_REQUEST['pageMode']) && $_REQUEST['pageMode']=="js") { require "content/".$pageID.".php"; exit; } // ELSE - REST OF WEBSITE WILL BE GENERATED USING THE page VARIABLE The Links <a class='btnMenu' href='?page=home'>Home Page</a> <a class='btnMenu' href='?page=about'>About</a> <a class='btnMenu' href='?page=Services'>Services</a> <a class='btnMenu' href='?page=contact'>Contact</a> The Javascript $(function() { $(".btnMenu").click(function(){return doNav(this);}); }); function doNav(objCaller) { var sPage = $(objCaller).attr("href").substring(6,255); $.get("index.php", { page: sPage, pageMode: 'js'}, function(data) { ("#siteContent").html(data).scrollTop(0); }); return false; } Forgive me if there are any errors, as just copied and pasted from my script then removed a bunch of junk to simplify it as still prototyping/white boarding the project its in. So yes it does look a little nasty at the moment. REASONS WHY: The main reason is bandwidth and speed, This will allow other scripts to run and control the site/application a little better and yes it will need to be locked down with some coding. -- FURTHER EXAMPLE-- INSERT PHP AT TOP <?php // PHP CODE HERE ?> <html> <head> <link rel="stylesheet" type="text/css" href="style.css" /> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript" src="scripts.js"></script> </head> <body> <div class='siteBody'> <div class='siteHeader'> <?php foreach ($pageList as $key => $value) { if ($pageID == $key) {$btnClass="btnMenuSel";} else {$btnClass="btnMenu";} echo "<a class='$btnClass' href='?page=".$key."'>".$pageList[$key]."</a>"; } ?> </div><div id="siteContent" style='margin-top:10px;'> <?php require "content/".$pageID.".php"; ?> </div><div class='siteFooter'> </div> </div> </body> </html>

  • Tablesorter - filter inside input fields and values

    - by Zeracoke
    I have a small quest to accomplish, and I reached a point when nothing works... So the problem is. I have a paged table with a lot of input fields inside the rows with values, and I would like to search inside these values. Let me Show this, I hope that somebody will got the idea what I should do... <script type="text/javascript"> // add parser through the tablesorter addParser method $.tablesorter.addParser({ id: 'inputs', is: function(s) { return false; }, format: function(s, table, cell, cellIndex) { var $c = $(cell); // return 1 for true, 2 for false, so true sorts before false if (!$c.hasClass('updateInput')) { $c .addClass('updateInput') .bind('keyup', function() { $(table).trigger('updateCell', [cell, false]); // false to prevent resort }); } return $c.find('input').val(); }, type: 'text' }); $(function() { $('table').tablesorter({ widgets: ['zebra', 'stickyHeaders', 'resizable', 'filter'], widgetOptions: { stickyHeaders : '', // number or jquery selector targeting the position:fixed element stickyHeaders_offset : 110, // added to table ID, if it exists stickyHeaders_cloneId : '-sticky', // trigger "resize" event on headers stickyHeaders_addResizeEvent : true, // if false and a caption exist, it won't be included in the sticky header stickyHeaders_includeCaption : true, // The zIndex of the stickyHeaders, allows the user to adjust this to their needs stickyHeaders_zIndex : 2, // jQuery selector or object to attach sticky header to stickyHeaders_attachTo : null, // scroll table top into view after filtering stickyHeaders_filteredToTop: true, resizable: true, filter_onlyAvail : 'filter-onlyAvail', filter_childRows : true, filter_startsWith : true, filter_useParsedData : true, filter_defaultAttrib : 'data-value' }, headers: { 1: {sorter: 'inputs', width: '50px'}, 2: {sorter: 'inputs'}, 3: {sorter: 'inputs'}, 4: {sorter: 'inputs'}, 5: {sorter: 'inputs'}, 6: {sorter: 'inputs'}, 7: {sorter: 'inputs', width: '100px'}, 8: {sorter: 'inputs', width: '140px'}, 9: {sorter: 'inputs'}, 10: {sorter: 'inputs'}, 11: {sorter: 'inputs'}, } }); $('table').tablesorterPager({container: $(".pager"), positionFixed: false, size: 50, pageDisplay : $(".pagedisplay"), pageSize : $(".pagesize"), }); $("#table1").tablesorter(options); /* make second table scroll within its wrapper */ options.widgetOptions.stickyHeaders_attachTo = '.wrapper'; // or $('.wrapper') $("#table2").tablesorter(options); }); </script> The structure of the tables: <tr class="odd" style="display: table-row;"> <form action="/self.php" method="POST"> </form><input type="hidden" name="f" value="data"> <td><input type="hidden" name="mod_id" value="741">741</td> <td class="updateInput"><input type="text" name="name" value="Test User Name"></td> <td class="updateInput"><input type="text" name="address" value="2548451 Random address"></td> <td class="updateInput"><input type="email" name="email" value=""></td> <td class="updateInput"><input type="text" name="entitlement" value="none"></td> <td class="updateInput"><input type="text" name="card_number" value="6846416548644352"></td> <td class="updateInput"><input type="checkbox" name="verify" value="1" checked=""></td> <td class="updateInput"><input type="checkbox" name="card_sended" value="1" checked=""></td> <td class="updateInput"><input type="text" name="create_date" value="2014-02-12 21:09:16"></td> <td class="updateInput"><a href="self.php?f=data&amp;del=741">X</a></td> <td class="updateInput"><input type="submit" value="SAVE"></td><td class="updateInput"></td></tr> So the thing is I don't know how to configure the filter to search these values... I already added some options, but none of them are working... Any help would be great!

  • Help with optimizing C# function via C and/or Assembly

    - by MusiGenesis
    I have this C# method which I'm trying to optimize: // assume arrays are same dimensions private void DoSomething(int[] bigArray1, int[] bigArray2) { int data1; byte A1; byte B1; byte C1; byte D1; int data2; byte A2; byte B2; byte C2; byte D2; for (int i = 0; i < bigArray1.Length; i++) { data1 = bigArray1[i]; data2 = bigArray2[i]; A1 = (byte)(data1 >> 0); B1 = (byte)(data1 >> 8); C1 = (byte)(data1 >> 16); D1 = (byte)(data1 >> 24); A2 = (byte)(data2 >> 0); B2 = (byte)(data2 >> 8); C2 = (byte)(data2 >> 16); D2 = (byte)(data2 >> 24); A1 = A1 > A2 ? A1 : A2; B1 = B1 > B2 ? B1 : B2; C1 = C1 > C2 ? C1 : C2; D1 = D1 > D2 ? D1 : D2; bigArray1[i] = (A1 << 0) | (B1 << 8) | (C1 << 16) | (D1 << 24); } } The function basically compares two int arrays. For each pair of matching elements, the method compares each individual byte value and takes the larger of the two. The element in the first array is then assigned a new int value constructed from the 4 largest byte values (irrespective of source). I think I have optimized this method as much as possible in C# (probably I haven't, of course - suggestions on that score are welcome as well). My question is, is it worth it for me to move this method to an unmanaged C DLL? Would the resulting method execute faster (and how much faster), taking into account the overhead of marshalling my managed int arrays so they can be passed to the method? If doing this would get me, say, a 10% speed improvement, then it would not be worth my time for sure. If it was 2 or 3 times faster, then I would probably have to do it. Note: please, no "premature optimization" comments, thanks in advance. This is simply "optimization".

  • Path to background in servlet

    - by kapil chhattani
    //the below line is the element of my HTML form which renders the image sent by the servlet written further below. <img style="margin-left:91px; margin-top:-6px;" class="image" src="http://www.abcd.com/captchaServlet"> I generate a captcha code using the following code in java. public class captchaServlet extends HttpServlet { protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { int width = 150; int height = 50; int charsToPrint = 6; String elegibleChars = "ABCDEFGHJKLMPQRSTUVWXYabcdefhjkmnpqrstuvwxy1234567890"; char[] chars = elegibleChars.toCharArray(); StringBuffer finalString = new StringBuffer(); for ( int i = 0; i < charsToPrint; i++ ) { double randomValue = Math.random(); int randomIndex = (int) Math.round(randomValue * (chars.length - 1)); char characterToShow = chars[randomIndex]; finalString.append(characterToShow); } System.out.println(finalString); BufferedImage bufferedImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB); Graphics2D g2d = bufferedImage.createGraphics(); Font font = new Font("Georgia", Font.BOLD, 18); g2d.setFont(font); RenderingHints rh = new RenderingHints( RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); rh.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY); g2d.setRenderingHints(rh); GradientPaint gp = new GradientPaint(0, 0, Color.BLUE, 0, height/2, Color.black, true); g2d.setPaint(gp); g2d.fillRect(0, 0, width, height); g2d.setColor(new Color(255, 255, 0)); Random r = new Random(); int index = Math.abs(r.nextInt()) % 5; char[] data=new String(finalString).toCharArray(); String captcha = String.copyValueOf(data); int x = 0; int y = 0; for (int i=0; i<data.length; i++) { x += 10 + (Math.abs(r.nextInt()) % 15); y = 20 + Math.abs(r.nextInt()) % 20; g2d.drawChars(data, i, 1, x, y); } g2d.dispose(); response.setContentType("image/png"); OutputStream os = response.getOutputStream(); ImageIO.write(bufferedImage, "png", os); os.close(); } protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { processRequest(request, response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { processRequest(request, response); } } But in the above code background is also generated using the setPaint menthod I am guessing. I want the background to be some image from my local machine whoz URL i should be able to mention like URL url=this.getClass().getResource("Desktop/images.jpg"); BufferedImage bufferedImage = ImageIO.read(url); I am just writing the above two lines for making the reader understand better what the issue is. Dont want to use the exact same commands. All I want is the the background of the captcha code generated should be an image of my choice.

  • Infinite sharing system (PHP/MySQLi)

    - by Toine Lille
    I'm working on a discount system for whichever customer shares a product and brings in new customers. Each unique visit = $0.05 off, each new customer = $0.50 off (it's a cheap product so yeah, no big numbers). When a new customer shares the site, the customer initially responsible for the new customer (if any) will get half of the new customer's discount as well. The initial customer would get a fourth for the next level and the new customer half of that, etc, creating a tree or pyramid that way that could be infinite. Initial customer ($1.35 discount: 2 new+3 visits + half of 1 new+2 visits) Visitor ($0) Visitor ($0) New customer ($0.60) Visitor ($0) Visitor ($0) Newer customer ($0) New customer ($0) Visitor ($0) The customers are saved along with their IP addresses (bin2hex(inet_pton)) in a database table (customers) with info like a unique id, e-mail address and first date/time the purchased a product (= time of registration). The shares are saved in a separate table within the same database (sharing). Each unique IP addresses that visits the site creates a new row featuring the IP address (also saved as bin2hex(inet_pton)), the id of the customer who shared it and the date/time of the visit. Sharing goes via URL, featuring a GET element containing the customer's id. Visits and new customers overlap, as visits will always occur before the new customer does. That's fine. The date/times are used just to make it a little more secure (I also use the IP along with cookies to see if people cheat the system). If an IP is already in the sharing or customer tables, it does not count and will not create a new entry. Now the problem is, how to make the infinity happen and apply the different values to it? That's all I'd need to know. It needs to calculate the discount for each customer separately, but also allow for monitoring altogether (though that's just a matter of passing all ID's through it). I figured I'd start (after the database connection) with $stmt = $con->prepare('SELECT ip,datetime FROM sharing WHERE sender=?'); $stmt->bind_param('i',$customerid); $stmt->execute(); $stmt->store_result(); $discount = $discount + ($stmt->num_rows * 0.05); $stmt->bind_result($ip,$timeofsharing); to translate all the visits to $0.05 of discount each. To check for the new customers that came from these visits, I wrote the following: while ($sql->fetch()) { $stmt2 = $con->prepare("SELECT datetime FROM users WHERE ip=?"); $stmt2->bind_param('s',$ip); $stmt2->execute(); $stmt2->store_result(); $stmt2->bind_result($timeofpurchase); Followed by a little more security comparing the datetimes: while ($stmt2->fetch()) { if (strtotime($timeofpurchase) < strtotime($timeofsharing)) { $discount = $discount + $0.50; } But this is just for the initial customer's direct results. If I'd want to check for the next level, I'd basically have to put the exact same check and loop in itself, checking each new customer the initial customer they brought to the site, and then for the next level again to check all of the newer customers, etc, etc. What to do? / Where to go? / What would be the correct practice for this? Thanks!

  • Drupal menu with submenus only shows submenu of current page. NOT a CSS problem

    - by jordanstephens
    This is not a CSS problem. The HTML isn't there. I need the menu, with submenus to exist in HTML on EACH page. Right now, the submenu only exists in HTML for the submenu related to the page being currently viewed. Here's an example of what it SHOULD be like. <ul id="menu"> <li>Page1 <ul class="sub"> <li>sub1.1</li> <li>sub1.2</li> <li>sub1.3</li> <li>sub1.4</li> </ul> </li> <li>Page2 <ul class="sub"> <li>sub2.1</li> <li>sub2.2</li> <li>sub2.3</li> <li>sub2.4</li> </ul> </li> <li>Page3 <ul class="sub"> <li>sub3.1</li> <li>sub3.2</li> <li>sub3.3</li> <li>sub3.4</li> </ul> </li> </ul> But here is what is actually happening (say I'm currently viewing Page2): <ul id="menu"> <li>Page1</li> <li>Page2 <ul class="sub"> <li>sub2.1</li> <li>sub2.2</li> <li>sub2.3</li> <li>sub2.4</li> </ul> </li> <li>Page3</li> </ul> Additionally, and maybe this doesn't have anything to do with it, but whichever list item <li> element is relative to the page i am currently on is given these classes expanded active-trail and any other <li> is given collapsed class. The classes aren't really so much of an issue, the problem is just that the content (html) isn't there. Does anyone have any idea what's going on here. I feel like I've been digging in the Drupal Admin menus forever now. I feel like it's got to have a PHP solution in the template file or something, but I don't know Drupal super well at this point. Thank you!

  • Control XML serialization of Dictionary<K, T>

    - by Luca
    I'm investigating about XML serialization, and since I use lot of dictionary, I would like to serialize them as well. I found the following solution for that (I'm quite proud of it! :) ). [XmlInclude(typeof(Foo))] public class XmlDictionary<TKey, TValue> { /// <summary> /// Key/value pair. /// </summary> public struct DictionaryItem { /// <summary> /// Dictionary item key. /// </summary> public TKey Key; /// <summary> /// Dictionary item value. /// </summary> public TValue Value; } /// <summary> /// Dictionary items. /// </summary> public DictionaryItem[] Items { get { List<DictionaryItem> items = new List<DictionaryItem>(ItemsDictionary.Count); foreach (KeyValuePair<TKey, TValue> pair in ItemsDictionary) { DictionaryItem item; item.Key = pair.Key; item.Value = pair.Value; items.Add(item); } return (items.ToArray()); } set { ItemsDictionary = new Dictionary<TKey,TValue>(); foreach (DictionaryItem item in value) ItemsDictionary.Add(item.Key, item.Value); } } /// <summary> /// Indexer base on dictionary key. /// </summary> /// <param name="key"></param> /// <returns></returns> public TValue this[TKey key] { get { return (ItemsDictionary[key]); } set { Debug.Assert(value != null); ItemsDictionary[key] = value; } } /// <summary> /// Delegate for get key from a dictionary value. /// </summary> /// <param name="value"></param> /// <returns></returns> public delegate TKey GetItemKeyDelegate(TValue value); /// <summary> /// Add a range of values automatically determining the associated keys. /// </summary> /// <param name="values"></param> /// <param name="keygen"></param> public void AddRange(IEnumerable<TValue> values, GetItemKeyDelegate keygen) { foreach (TValue v in values) ItemsDictionary.Add(keygen(v), v); } /// <summary> /// Items dictionary. /// </summary> [XmlIgnore] public Dictionary<TKey, TValue> ItemsDictionary = new Dictionary<TKey,TValue>(); } The classes deriving from this class are serialized in the following way: <FooDictionary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Items> <DictionaryItemOfInt32Foo> <Key/> <Value/> </DictionaryItemOfInt32XmlProcess> <Items> This give me a good solution, but: How can I control the name of the element DictionaryItemOfInt32Foo What happens if I define a Dictionary<FooInt32, Int32> and I have the classes Foo and FooInt32? Is it possible to optimize the class above? THank you very much!

  • Javascript/Jquery Super Scrollorama Navigation Issues

    - by Rosencruez
    On a Wordpress site I am currently working on, my client wanted the different sections of the front page to slide up from the bottom and cover up the previous section, like a wipe or slide transition. Using super scrollorama found here: http://johnpolacek.github.com/superscrollorama/, I managed to achieve the desired result. Next, I needed to create a navigation menu on the front page only. I did so, and set anchors at various different points on the pages. I also used the scrollTo library for scolling animations when I click the nav menu links. However, there are a number of problems I have encountered: When at the top and I click "showcase", it brings me down to the showcase section, but the products section (the div right after it) is overlapping it. Other divs seems to have the same problem of the following divs overlapping the current one I can only navigate forwards. When I try to go backwards, it won't (except for "Home") I thought it might have something to do with the CSS "top" property of the divs, so I tried resetting them every time the click function kicked in, but it didn't work. So I removed it for the time being. Currently set the javascript to prevent the default action of scrolling to the anchors and instead setting it to scroll to the actual divs themselves. However, I'm still having the same issues. Here is the site I am currently working on: http://breathe.simalam.ca/ Here is the javascript for the scrolling: $(document).ready(function() { jQuery('.home-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo(0, 1000, {queue:true}); }); jQuery('.showcase-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo('#showcase_content', 1000, {queue:true}); }); jQuery('.products-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo('#products_content', 1000, {queue:true}); }); jQuery('.about-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo('#about_content', 1000, {queue:true}); }); jQuery('.locator-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo('#locator_content', 1000, {queue:true}); }); jQuery('.contact-link').click(function(e){ e.preventDefault(); jQuery(window).scrollTo('#contact_content', 1000, {queue:true}); }); }); scrollorama code: $(document).ready(function() { $('#wrapper').css('display','block'); var controller = $.superscrollorama(); var pinDur = 4000; /* set duration of pin scroll in pixels */ // create animation timeline for pinned element var pinAnimations = new TimelineLite(); pinAnimations .append([ TweenMax.to($('#showcase'), .5, {css:{top:0}}) ], .5) .append([ TweenMax.to($('#products'), .5, {css:{top:0}}) ], .5) .append([ TweenMax.to($('#about'), .5, {css:{top:0}}) ], .5) .append([ TweenMax.to($('#locator'), .5, {css:{top:0}}) ], .5) .append([ TweenMax.to($('#contact'), .5, {css:{top:0}}) ], .5) .append(TweenMax.to($('#pin-frame-unpin'), .5, {css:{top:'100px'}})); controller.pin($('#examples-pin'), pinDur, { anim:pinAnimations, onPin: function() { $('#examples-pin').css('height','100%'); }, onUnpin: function() { $('#examples-pin').css('height','2000px'); } }); }); All of the section divs are inside a parent div. The section divs all have a height, width, and top of 100%. The parent div containing all of these section divs are as follows: #examples-pin { position: relative; /* relative positioning for transitions to work? */ width: 101%; /* max width */ height: 2000px; /* height of 2000px for now */ overflow: hidden; /* hide the overflow for transitions to work */ margin-bottom: -200px; /* negative bottom margin */ }

I think there is something mess with .children, maybe it can handle only the first occurrence? Thanks for help

  • How to optimize this javascript code?

    I have a jsp which uses a lot of javascript and it's just not fast enough. I would like to optimize it so first, here's a part of the code: In the jsp I have the initialization: window.onload = function () { formCollection.pageSize.value = "<%= pagingSize%>"; elemCollection = iDom3.Table.all["spis"].XML.DOM; <% if (resultList != null) { %> elementsNumber = <%= resultList.size() %>; <%} else { %> elementsNumber = 0; <% } %> contextPath = "<%= request.getContextPath() %>"; } In my js file I have two types of js functions: // gets the first element and sets it's value to all the other; //the selectSingleNode function is used because I use XSLT transformation //to generate the table _setTehJed = function(){ var resultId = formCollection.elements["idTehJedinice_spis_1"].value; var resultText = formCollection.elements["tehnicka_spis_1"].value; if (resultId != ""){ var counter = 1; while (counter<elementsNumber){ counter++; if(formCollection.elements["idTehJedinice_spis_"+counter] != null){ formCollection.elements["idTehJedinice_spis_"+counter].value=resultId; formCollection.elements["tehnicka_spis_"+counter].value=resultText; } var node=elemCollection.selectSingleNode("/suite/table/rows/row[@id = 'spis_"+counter+"']/data[@col = 'tehnicka']/title"); node.text=resultText; var node2=elemCollection.selectSingleNode("/suite/table/rows/row[@id = 'spis_"+counter+"']/data[@col = 'idTehJedinice']/title"); node2.text=resultId; } } } // sets the elements checkbox to checked or unchecked _SelectCheckRokCuvanja = { all : [], Item : function (oItem, sId) { this.all["spis_"+sId] = oItem.value; if (oItem.checked) { elemCollection.selectSingleNode("/suite/table/rows/row[@id = 'spis_"+sId+"']/data[@col = 'rokCheck']").setAttribute("default", "true"); }else{ elemCollection.selectSingleNode("/suite/table/rows/row[@id = 'spis_"+sId+"']/data[@col = 'rokCheck']").setAttribute("default", "false"); } } } I've used these tips: http://blogs.msdn.com/b/ie/archive/2006/08/28/728654.aspx http://code.google.com/speed/articles/optimizing-javascript.html but I still think something could be done like defining the functions like this: In the jsp: window.onload = function () { iDom3.DigitalnaArhivaPrihvat.formCollection=document.forms["controller"]; iDom3.DigitalnaArhivaPrihvat.formCollection.pageSize.value = "<%= pagingSize%>"; iDom3.DigitalnaArhivaPrihvat.elemCollection = iDom3.Table.all["spis"].XML.DOM; <% if (resultList != null) { %> iDom3.DigitalnaArhivaPrihvat.elementsNumber = <%= resultList.size() %> <%} else { %> iDom3.DigitalnaArhivaPrihvat.elementsNumber = 0; <% } %> } in the js: iDom3.DigitalnaArhivaPrihvat = { formCollection:null, elemCollection:null, elementsNumber:null, _setTehJed : function(){ var resultId = this.formCollection.elements.idTehJedinice_spis_1.value; var resultText = this.formCollection.elements.tehnicka_spis_1.value; if (resultId != ""){ var counter = 1; while (counter<this.elementsNumber){ counter++; if(this.formCollection.elements["idTehJedinice_spis_"+counter] !== null){ this.formCollection.elements["idTehJedinice_spis_"+counter].value=resultId; this.formCollection.elements["tehnicka_spis_"+counter].value=resultText; } var node=this.elemCollection.selectSingleNode("/suite/table/rows/row[@id = 'spis_"+counter+"']/data[@col = 'tehnicka']/title"); node.text=resultText; var node2=this.elemCollection.selectSingleNode("/suite/table/rows/row[@id = 'spis_"+counter+"']/data[@col = 'idTehJedinice']/title"); node2.text=resultId; } } }, _SelectCheckRokCuvanja = { all : [], Item : function (oItem, sId) { this.all["spis_"+sId] = oItem.value; if (oItem.checked) { this.elemCollection.selectSingleNode("/suite/table/rows/row[@id = 'spis_"+sId+"']/data[@col = 'rokCheck']").setAttribute("default", "true"); }else{ this.elemCollection.selectSingleNode("/suite/table/rows/row[@id = 'spis_"+sId+"']/data[@col = 'rokCheck']").setAttribute("default", "false"); } } } but the problem is scoping (if I do it like this, the second function does not execute properly). Any suggestions?

  • IE7 rendering bug: Heading before a floated list

    - by Tomalak
    Can somebody please explain this IE7 bug to me? It occurs in Standards and Quirks mode rendering, it does not occur in Firefox, Chrome or IE8 (though switching the rendering engine via IE8 developer tools will provoke it). Here's the HTML to reproduce the behavior: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title>Test</title> <style type="text/css"> /* h1 { margin: 0px; } */ ul { padding: 0; margin: 0; list-style-type: none; } ul li { float: left; width: 140px; padding: 3px; } div { clear: left; padding: 3px; } div, li { background-color: OrangeRed; } /* ul { border: 1px solid blue; } */ </style> </head> <body> <h1>Heading 1</h1> <ul class="t"> <li>bla 1</li><li>bla 2</li><li>bla 3</li> </ul> <div>yada</div> </body> </html> This renders a floated <ul> above a <div> (supposed to be a tabbed user interface). There's an unexplained gap between the <div> and the <ul>. Now do one of the following: Uncomment the CSS rule for <h1>. The gap disappears and the list is rendered tight to the <div>, but also very close to the <h1>. Alternatively, uncomment the CSS rule for <ul>. Now a narrow blue border is rendered above the <ul>, but the gap disappears. My questions: How can the <h1> margin (I suppose any block level element with a defined margin will do) affect the space below the list? Can I prevent this from happening without having to set header margins to 0 or messing with the <ul> borders (setting border-width: 0; does not work BTW)? I suppose it is connected to the <ul> having no width because it has only floated children. Maybe someone with more insight into IE7 peculiarities than I have can explain what the rendering engine is doing here. Thanks!

  • How to use XSLT to tag specific nodes with unique, sequential, increasing integer ids?

    - by ~otakuj462
    Hi, I'm trying to use XSLT to transform a document by tagging a group of XML nodes with integer ids, starting at 0, and increasing by one for each node in the group. The XML passed into the stylesheet should be echoed out, but augmented to include this extra information. Just to be clear about what I am talking about, here is how this transformation would be expressed using DOM: states = document.getElementsByTagName("state"); for( i = 0; i < states.length; i++){ states.stateNum = i; } This is very simple with DOM, but I'm having much more trouble doing this with XSLT. The current strategy I've devised has been to start with the identity transformation, then create a global variable which selects and stores all of the nodes that I wish to number. I then create a template that matches that kind of node. The idea, then, is that in the template, I would look up the matched node's position in the global variable nodelist, which would give me a unique number that I could then set as an attribute. The problem with this approach is that the position function can only be used with the context node, so something like the following is illegal: <template match="state"> <variable name="stateId" select="@id"/> <variable name="uniqueStateNum" select="$globalVariable[@id = $stateId]/position()"/> </template> The same is true for the following: <template match="state"> <variable name="stateId" select="@id" <variable name="stateNum" select="position($globalVariable[@id = $stateId])/"/> </template> In order to use position() to look up the position of an element in $globalVariable, the context node must be changed. I have found a solution, but it is highly suboptimal. Basically, in the template, I use for-each to iterate through the global variable. For-each changes the context node, so this allows me to use position() in the way I described. The problem is that this turns what would normally be an O(n) operation into an O(n^2) operation, where n is the length of the nodelist, as this require iterating through the whole list whenever the template is matched. I think that there must be a more elegant solution. Altogether, here is my current (slightly simplified) xslt stylesheet: <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:s="http://www.w3.org/2005/07/scxml" xmlns="http://www.w3.org/2005/07/scxml" xmlns:c="http://msdl.cs.mcgill.ca/" version="1.0"> <xsl:output method="xml"/> <!-- we copy them, so that we can use their positions as identifiers --> <xsl:variable name="states" select="//s:state" /> <!-- identity transform --> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="s:state"> <xsl:variable name="stateId"> <xsl:value-of select="@id"/> </xsl:variable> <xsl:copy> <xsl:apply-templates select="@*"/> <xsl:for-each select="$states"> <xsl:if test="@id = $stateId"> <xsl:attribute name="stateNum" namespace="http://msdl.cs.mcgill.ca/"> <xsl:value-of select="position()"/> </xsl:attribute> </xsl:if> </xsl:for-each> <xsl:apply-templates select="node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet> I'd appreciate any advice anyone can offer. Thanks.

  • Control XML serialization of generic types

    - by Luca
    I'm investigating about XML serialization, and since I use lot of dictionary, I would like to serialize them as well. I found the following solution for that (I'm quite proud of it! :) ). [XmlInclude(typeof(Foo))] public class XmlDictionary<TKey, TValue> { /// <summary> /// Key/value pair. /// </summary> public struct DictionaryItem { /// <summary> /// Dictionary item key. /// </summary> public TKey Key; /// <summary> /// Dictionary item value. /// </summary> public TValue Value; } /// <summary> /// Dictionary items. /// </summary> public DictionaryItem[] Items { get { List<DictionaryItem> items = new List<DictionaryItem>(ItemsDictionary.Count); foreach (KeyValuePair<TKey, TValue> pair in ItemsDictionary) { DictionaryItem item; item.Key = pair.Key; item.Value = pair.Value; items.Add(item); } return (items.ToArray()); } set { ItemsDictionary = new Dictionary<TKey,TValue>(); foreach (DictionaryItem item in value) ItemsDictionary.Add(item.Key, item.Value); } } /// <summary> /// Indexer base on dictionary key. /// </summary> /// <param name="key"></param> /// <returns></returns> public TValue this[TKey key] { get { return (ItemsDictionary[key]); } set { Debug.Assert(value != null); ItemsDictionary[key] = value; } } /// <summary> /// Delegate for get key from a dictionary value. /// </summary> /// <param name="value"></param> /// <returns></returns> public delegate TKey GetItemKeyDelegate(TValue value); /// <summary> /// Add a range of values automatically determining the associated keys. /// </summary> /// <param name="values"></param> /// <param name="keygen"></param> public void AddRange(IEnumerable<TValue> values, GetItemKeyDelegate keygen) { foreach (TValue v in values) ItemsDictionary.Add(keygen(v), v); } /// <summary> /// Items dictionary. /// </summary> [XmlIgnore] public Dictionary<TKey, TValue> ItemsDictionary = new Dictionary<TKey,TValue>(); } The classes deriving from this class are serialized in the following way: <XmlProcessList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Items> <DictionaryItemOfInt32Foo> <Key/> <Value/> </DictionaryItemOfInt32XmlProcess> <Items> This give me a good solution, but: How can I control the name of the element DictionaryItemOfInt32Foo What happens if I define a Dictionary<FooInt32, Int32> and I have the classes Foo and FooInt32? Is it possible to optimize the class above? THank you very much!

  • Why does jQuery's $().each() function seem to be losing track of the DOM?

    - by Nate Wagar
    I've recently started encountering a very strange problem. To be honest, I'm not entirely sure how to describe it other than to just show it. Here's the relevant HTML: <div class="component container w100 noEdit" id="contentWrapper"> <div class="component container w50" id="container1"> <div class="component text w50" id="text1"> Text1 </div> </div> <div class="component container w25" id="container2"> Container2 </div> <div class="component container w25" id="container3"> Container3 </div> <div class="component container w25" id="container4"> Container4 </div> </div> And the relevant JavaScript: $(document).ready(function () { //Add the Grab Bar to container components on the page. $('.component').each(wrapComponentForEdit); $('#contentWrapper').sortable(); $('#contentWrapper').disableSelection(); }); var wrapComponentForEdit = function() { if (!$(this).hasClass('noEdit')) { $(this).html('<div class="componentBorder">' + $(this).html() + '</div>'); $(this).prepend('<div class="grabBar_l"><div class="grabBar_r"><div class="grabBar"></div></div></div>'); alert($(this).attr('id')); } } The end result of this is that I see an alert pop up for container1, text1, container2, container3, container 4. And yet only the containers (not the text) end up with the visual changes that the $().each() is supposed to make. Anyone have any idea what the heck is going on? Thanks! EDIT - A different way to do it, that still fails I tried this, with the same result: $(document).ready(function () { //Add the Grab Bar to container components on the page. var matched = $('.component'); var componentCount = $(matched).size(); for (i = 0; i < componentCount; i++) { wrapComponentForEdit($(matched).eq(i)); } $('#contentWrapper').sortable({ handle: '.grabBarBit', tolerance: 'pointer'}); $('#contentWrapper').disableSelection(); }); var wrapComponentForEdit = function(component) { if (!$(component).hasClass('noEdit')) { $(component).html('<div class="grabBar_l grabBarBit"><div class="grabBar_r grabBarBit"><div class="grabBar grabBarBit"></div></div></div><div class="componentBorder">' + $(component).html() + '</div>'); alert($(component).attr('id')); } } EDIT 2: Another alternate method, but this one works I tried another way of doing things, and this way it works. However, the initial question still stands. Judging by how this new way works, it seems to me that the DOM is being updated, but jQuery isn't updating with it, so it loses track of the child element. $(document).ready(function () { //Add the Grab Bar to container components on the page. var componentCount = $('.component').size(); for (i = 0; i < componentCount; i++) { wrapComponentForEdit($('.component').eq(i)); } $('#contentWrapper').sortable({ handle: '.grabBarBit', tolerance: 'pointer'}); $('#contentWrapper').disableSelection(); }); var wrapComponentForEdit = function(component) { if (!$(component).hasClass('noEdit')) { $(component).html('<div class="grabBar_l grabBarBit"><div class="grabBar_r grabBarBit"><div class="grabBar grabBarBit"></div></div></div><div class="componentBorder">' + $(component).html() + '</div>'); alert($(component).attr('id')); } }

  • C++ class functions calling fortran subroutine

    - by user2863626
    Okay so I am trying to make my code work. It is a simple C++ program with a class "CArray". This class has 2 properties, the array size, and the value. I want the main C++ program to create two instances of the class CArray. In the class CArray, I have a function called "AddArray( CArray )" where it adds another array to the current array. The problem I am stuck with, is that I want the function "AddArray" to add the two arrays in fortran. I know, much more complicated, but that is what I need. I am having issues with linking the two inside the class code. #include <iostream> using namespace std; class CArray { public: CArray(); ~CArray(); int Size; int* Val; void SetSize( int ); void SetValues(); void GetArray(); extern "C" { void Add( int*, int*, int*, int*); void Subtract( int*, int*, int*, int*); void Muliply( int*, int*, int *, int* ); } void AddArray( CArray ); void SubtractArray( CArray ); void MultiplyArray( CArray ); }; Also here is the CArray function file. #include "Array.h" #include <iostream> using namespace std; CArray::CArray() { } CArray::~CArray() { } void CArray::SetSize( int s ) { Size = s; for ( int i=0; i<s; i++ ) { Val = new int[Size]; } } void CArray::SetValues() { for ( int i=0; i<Size; i++ ) { cout << "Element " << i+1 << ": "; cin >> Val[i]; } } void CArray::GetArray() { for ( int i=0; i<Size; i++ ) { cout << Val[i] << " "; } } void CArray::AddArray( CArray a ) { if ( Size == a.Size ) { Add(&Val, &a.Val); } else { cout << "Array dimensions do not agree!" << endl; } } void CArray::SubtractArray( CArray a ) { Subtract( &Val, &a, &Size, &a.Size); GetArray(); } Here is my Fortran code. module SubtractArrays use ico_c_binding implicit none contains subroutine Subtract(a,b,s1,s2) bind(c,name='Subtract') integer s1,s2 integer a(s1),b(s2) if ( s1.eq.s2 ) do i=1,s1 a(i) = a(i) - b(i) end return end end If someone could just help me with setting me up to send arrays of integers from C++ classes to fortran I would greatly appreciate it!

  • Ajax using Rails

    - by Steve
    Hi, I have a favourite and un-favourite functionality in my application and I am using jQuery. This functionality works partially. The page gets loaded, and when I click the 'favourite' button(it is inside add_favourite_div element), it sends a XHR request and the post is set as favourite. Then a new div called "remove_favourite_div" replaces its place.Now when I click the remove favourite(which is part of remove_favourite_div), it sends a normal http request inside of xhr. The structure when the page gets loaded first time <div id="favourite"> <div id="add_favourite_div"> <form method="post" id="add_favourite" action="/viewpost/add_favourite"> <div style="margin: 0pt; padding: 0pt; display: inline;"> <input type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" name="authenticity_token"> </div> <input type="hidden" value="3" name="Favourite[post_id]" id="Favourite_place_id"> <input type="hidden" value="2" name="Favourite[user_id]" id="Favourite_user_id"> <input type="submit" value="Favourite" name="commit"><br> </form> </div> </div> DOM after clicking on the unfavourite button <div id="favourite"> <div id="remove_favourite_div"> <form method="post" id="remove_favourite" action="/viewpost/remove_favourite"> <div style="margin: 0pt; padding: 0pt; display: inline;"> <input type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" name="authenticity_token"> </div> <input type="hidden" value="3" name="Favourite[post_id]" id="Favourite_place_id"> <input type="hidden" value="2" name="Favourite[user_id]" id="Favourite_user_id"> <input type="submit" value="UnFavourite" name="commit"><br> </form> </div> </div> In my application.js, I have two functions to trigger the xhr request $("#add_favourite").submit(function(){ alert("add favourite"); action = $(this).attr("action") $.post(action,$(this).serialize(),null,"script"); return false; }); $("#remove_favourite").submit(function(){ alert("remove favourite"); action = $(this).attr("action"); $.post(action,$(this).serialize(),null,"script"); return false; }); Here, when the post is initially not a favourite, favourite button is displayed and when i clicked on the button, $("#add_favourite").submit gets called and unfavourite form is displayed correctly, but now when I click on the un-favourite button, $("#remove_favourite").submit does not get called. The whole scenario is true in both ways, I mean favourite-Unfavourite and Unfavourite-favourite Can someone please help me to solve this Thanks

  • How can I clear content without getting the dreaded "stop running this script?" dialog?

    - by Cheeso
    I have a div, that holds a div. like this: <div id='reportHolder' class='column'> <div id='report'> </div> </div> Within the inner div, I add a bunch (7-12) of pairs of a and div elements, like this: <h4><a>Heading1</a></h4> <div> ...content here....</div> The total size of the content, is maybe 200k. Each div just contains a fragment of HTML. Within it, there are numerous <span> elements, containing other html elements, and they nest, to maybe 5-8 levels deep. Nothing really extraordinary, I don't think. After I add all the content, I then create an accordion. like this: $('#report').accordion({collapsible:true, active:false}); This all works fine. The problem is, when I try to clear or remove the report div, it takes a looooooong time, and I get 3 or 4 popups asking "Do you want to stop running this script?" I have tried several ways: option 1: $('#report').accordion('destroy'); $('#report').remove(); $("#reportHolder").html("<div id='report'> </div>"); option 2: $('#report').accordion('destroy'); $('#report').html(''); $("#reportHolder").html("<div id='report'> </div>"); option 3: $('#report').accordion('destroy'); $("#reportHolder").html("<div id='report'> </div>"); after getting a suggestion in the comment, I also tried: option 4: $('#report').accordion('destroy'); $('#report').empty(); $("#reportHolder").html("<div id='report'> </div>"); No matter what, it hangs for a long while. The call to accordion('destroy') seems to not be the source of the delay. It's the erasure of the html content within the report div. This is jQuery 1.3.2. EDIT - fixed code typo. ps: this happens on FF3.5 as well as IE8 . Questions: What is taking so long? How can I remove content more quickly? Addendum I broke into the debugger in FF, during "option 4", and the stacktrace I see is: data() trigger() triggerHandler() add() each() each() add() empty() each() each() (?)() // <<-- this is the call to empty() ResetUi() // <<-- my code onclick I don't understand why add() is in the stack. I am removing content, not adding it. I'm afraid that in the context of the remove (all), jQuery does something naive. Like it grabs the html content, does the text replace to remove one html element, then calls .add() to put back what remains. Is there a way to tell jQuery to NOT propagate events when removing HTML content from the dom?

  • Having trouble with multiple Jquery libraries

    - by user3716971
    I've seen the posts about the no conflict but I'm not very code savvy and can't figure it out alone. I'm having trouble making two libraries work together. At the top I have the 1.9.1 library which controls a news ticker, and a carousel. Near the bottom there is a library 1.6.1, which controls a Dribbble feed. If I remove 1.6.1 everything but the dribbble feed works, and if I remove the 1.9.1 the dribbble feed is the only thing that works. I uploaded the website for you guys to check out. If you could edit my code to make it work that would be amazing, I don't have much knowledge of jquery. This version has a working dribbble feed at the very bottom http://michaelcullenbenson.com/MichaelCullenBenson.com/index.html and this version has a broken feed and everything else works. http://michaelcullenbenson.com/MichaelCullenBenson.com/index2.html Help would be AMAZING as the dribbble feed is the last element I'm trying to finish on my homepage and I'll be able to move on. <script type="text/javascript" src="js/jquery-1.9.1.min.js"></script> <script type="text/javascript" src="js/jquery.innerfade.js"></script> <script type="text/javascript"> $(document).ready( function(){ $('#news').innerfade({ animationtype: 'slide', speed: 600, timeout: 6000, type: 'random', containerheight: '1em' }); }); </script> <!-- Include all compiled plugins (below), or include individual files as needed --> <script src="utilcarousel-files/utilcarousel/jquery.utilcarousel.min.js"></script> <script src="utilcarousel-files/magnific-popup/jquery.magnific-popup.js"></script> <script src="js/responsive-nav.js"></script> <script> $(function() { $('#fullwidth').utilCarousel({ breakPoints : [[600, 1], [800, 2], [1000, 3], [1300, 4],], mouseWheel : false, rewind : true, autoPlay : true, pagination : false }); $('#fullwidth2').utilCarousel({ breakPoints : [[600, 1], [800, 2], [1000, 3], [1300, 4],], mouseWheel : false, rewind : true, autoPlay : true, pagination : false }); }); </script> <script> $(document).ready(function() { var movementStrength = 25; var height = movementStrength / $(window).height(); var width = movementStrength / $(window).width(); $("#aboutarea").mousemove(function(e){ var pageX = e.pageX - ($(window).width() / 2); var pageY = e.pageY - ($(window).height() / 2); var newvalueX = width * pageX * -1 - 25; var newvalueY = height * pageY * -1 - 50; $('#aboutarea').css("background-position", newvalueX+"px "+newvalueY+"px"); }); }); </script> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script> <script type="text/javascript" src="dribbble.js"></script> <script type="text/javascript"> $(function () { $('#user').dribbble({ player: 'MCBDesign', total: 1 }); }); </script>

  • bulls and cows game -- programming algorithm(python)

    - by IcyFlame
    This is a simulation of the game Cows and Bulls with three digit numbers I am trying to get the number of cows and bulls between two numbers. One of which is generated by the computer and the other is guessed by the user. I have parsed the two numbers I have so that now I have two lists with three elements each and each element is one of the digits in the number. So: 237 will give the list [2,3,7]. And I make sure that the relative indices are maintained.the general pattern is:(hundreds, tens, units). And these two lists are stored in the two lists: machine and person. ALGORITHM 1 So, I wrote the following code, The most intuitive algorithm: cows and bulls are initialized to 0 before the start of this loop. for x in person: if x in machine: if machine.index(x) == person.index(x): bulls += 1 print x,' in correct place' else: print x,' in wrong place' cows += 1 And I started testing this with different type of numbers guessed by the computer. Quite randomly, I decided on 277. And I guessed 447. Here, I got the first clue that this algorithm may not work. I got 1 cow and 0 bulls. Whereas I should have got 1 bull and 1 cow. This is a table of outputs with the first algorithm: Guess Output Expected Output 447 0 bull, 1 cow 1 bull, 1 cow 477 2 bulls, 0 cows 2 bulls, 0 cows 777 0 bulls, 3 cows 2 bulls, 0 cows So obviously this algorithm was not working when there are repeated digits in the number randomly selected by the computer. I tried to understand why these errors are taking place, But I could not. I have tried a lot but I just could not see any mistake in the algorithm(probably because I wrote it!) ALGORITHM 2 On thinking about this for a few days I tried this: cows and bulls are initialized to 0 before the start of this loop. for x in range(3): for y in range(3): if x == y and machine[x] == person[y]: bulls += 1 if not (x == y) and machine[x] == person[y]: cows += 1 I was more hopeful about this one. But when I tested this, this is what I got: Guess Output Expected Output 447 1 bull, 1 cow 1 bull, 1 cow 477 2 bulls, 2 cows 2 bulls, 0 cows 777 2 bulls, 4 cows 2 bulls, 0 cows The mistake I am making is quite clear here, I understood that the numbers were being counted again and again. i.e.: 277 versus 477 When you count for bulls then the 2 bulls come up and thats alright. But when you count for cows: the 7 in 277 at units place is matched with the 7 in 477 in tens place and thus a cow is generated. the 7 in 277 at tens place is matched with the 7 in 477 in units place and thus a cow is generated.' Here the matching is exactly right as I have written the code as per that. But this is not what I want. And I have no idea whatsoever on what to do after this. Furthermore... I would like to stress that both the algorithms work perfectly, if there are no repeated digits in the number selected by the computer. Please help me with this issue. P.S.: I have been thinking about this for over a week, But I could not post a question earlier as my account was blocked(from asking questions) because I asked a foolish question. And did not delete it even though I got 2 downvotes immediately after posting the question.

  • How does java.util.Collections.contains() perform faster than a linear search?

    - by The111
    I've been fooling around with a bunch of different ways of searching collections, collections of collections, etc. Doing lots of stupid little tests to verify my understanding. Here is one which boggles me (source code further below). In short, I am generating N random integers and adding them to a list. The list is NOT sorted. I then use Collections.contains() to look for a value in the list. I intentionally look for a value that I know won't be there, because I want to ensure that the entire list space is probed. I time this search. I then do another linear search manually, iterating through each element of the list and checking if it matches my target. I also time this search. On average, the second search takes 33% longer than the first one. By my logic, the first search must also be linear, because the list is unsorted. The only possibility I could think of (which I immediately discard) is that Java is making a sorted copy of my list just for the search, but (1) I did not authorize that usage of memory space and (2) I would think that would result in MUCH more significant time savings with such a large N. So if both searches are linear, they should both take the same amount of time. Somehow the Collections class has optimized this search, but I can't figure out how. So... what am I missing? import java.util.*; public class ListSearch { public static void main(String[] args) { int N = 10000000; // number of ints to add to the list int high = 100; // upper limit for random int generation List<Integer> ints; int target = -1; // target will not be found, forces search of entire list space long start; long end; ints = new ArrayList<Integer>(); start = System.currentTimeMillis(); System.out.print("Generating new list... "); for (int i = 0; i < N; i++) { ints.add(((int) (Math.random() * high)) + 1); } end = System.currentTimeMillis(); System.out.println("took " + (end-start) + "ms."); start = System.currentTimeMillis(); System.out.print("Searching list for target (method 1)... "); if (ints.contains(target)) { // nothing } end = System.currentTimeMillis(); System.out.println(" Took " + (end-start) + "ms."); System.out.println(); ints = new ArrayList<Integer>(); start = System.currentTimeMillis(); System.out.print("Generating new list... "); for (int i = 0; i < N; i++) { ints.add(((int) (Math.random() * high)) + 1); } end = System.currentTimeMillis(); System.out.println("took " + (end-start) + "ms."); start = System.currentTimeMillis(); System.out.print("Searching list for target (method 2)... "); for (Integer i : ints) { // nothing } end = System.currentTimeMillis(); System.out.println(" Took " + (end-start) + "ms."); } }

  • Referencing variables in a structure / C++

    - by user1628622
    Below, I provided a minimal example of code I created. I managed to get this code working, but I'm not sure if the practice being employed is sound. In essence, what I am trying to do is have the 'Parameter' class reference select elements in the 'States' class, so variables in States can be changed via Parameters. Questions I have: is the approach taken OK? If not, is there a better way to achieve what I am aiming for? Example code: struct VAR_TYPE{ public: bool is_fixed; // If is_fixed = true, then variable is a parameter double value; // Numerical value std::string name; // Description of variable (to identify it by name) }; struct NODE{ public: VAR_TYPE X, Y, Z; /* VAR_TYPE is a structure of primitive types */ }; class States{ private: std::vector <NODE_ptr> node; // shared ptr to struct NODE std::vector <PROP_DICTIONARY_ptr> property; // CAN NOT be part of Parameter std::vector <ELEMENT_ptr> element; // CAN NOT be part of Parameter public: /* ect */ void set_X_reference ( Parameter &T , int i ) { T.push_var( &node[i]->X ); } void set_Y_reference ( Parameter &T , int i ) { T.push_var( &node[i]->Y ); } void set_Z_reference ( Parameter &T , int i ) { T.push_var( &node[i]->Z ); } bool get_node_bool_X( int i ) { return node[i]->X.is_fixed; } // repeat for Y and Z }; class Parameter{ private: std::vector <VAR_TYPE*> var; public: /* ect */ }; int main(){ States S; Parameter P; /* Here I initialize and set S, and do other stuff */ // Now I assign components in States to Parameters for(int n=0 ; n<S.size_of_nodes() ; n++ ){ if ( S.get_node_bool_X(n)==true ){ S.set_X_reference ( P , n ); }; // repeat if statement for Y and Z }; /* Now P points selected to data in S, and I can * modify the contents of S through P */ return 0; }; Update The reason this issue cropped up is I am working with Fortran legacy code. To sum up this Fotran code - it's a numerical simulation of a flight vehicle. This code has a fairly rigid procedural framework one must work within, which comes with a pre-defined list of allowable Fortran types. The Fortran glue code can create an instance of a C++ object (in actuality, a reference from the perspective of Fortran), but is not aware what is contained in it (other means are used to extract C++ data into Fortran). The problem that I encountered is when a C++ module is dynamically linked to the Fortran glue code, C++ objects have to be initialized each instance the C++ code is called. This happens by virtue of how the Fortran template is defined. To avoid this cycle of re-initializing objects, I plan to use 'State' as a container class. The Fortran code allows a 'State' object, which has an arbitrary definition; but I plan to use it to harness all relevant information about the model. The idea is to use the Parameters class (which is exposed and updated by the Fortran code) to update variables in States.
