  • Programatically Drop an External Div in JSTree

    - by Ted Mosbey
    I have a grid (slickgrid) which creates and destroys rows on the fly. I know jstree uses .jstree-draggable to find the external drag targets, but applying them to the grid rows doesn't work - such that I've thought of using the grid drag, and on finish of the grid drag I want to call the jstree "drag_finish": function (data) jQuery.jstree._reference($("#Tree")).dnd_finish(); The problem is that there is some null data. How would I Programatically Drop an External Div? How does jstree apply the .jstree-draggable targets? I could add the .jstree-draggable class to the grid drag helper, but it doesnt seem to fire when dropped on the tree although it clearly has the class. Any guidance would be greatly appreciated. Regards.

  • Perl throws an error message about syntax

    - by Ben Dauphinee
    So, building off a question about string matching (this thread), I am working on implementing that info in solution 3 into a working solution to the problem I am working on. However, I am getting errors, specifically about this line of the below function: next if @$args->{search_in} !~ /@$cur[1]/; syntax error at ./db_index.pl line 16, near "next " My question as a perl newbie is what am I doing wrong here? sub search_for_key { my ($args) = @_; foreach $row(@{$args->{search_ary}}){ print "@$row[0] : @$row[1]\n"; } my $thiskey = NULL; foreach $cur (@{$args->{search_ary}}){ print "\n" . @$cur[1] . "\n" next if @$args->{search_in} !~ /@$cur[1]/; $thiskey = @$cur[0]; last; } return $thiskey; }

  • How to get parent node in Stanford's JavaNLP?

    - by roddik
    Hello. Suppose I have such chunk of a sentence: (NP (NP (DT A) (JJ single) (NN page)) (PP (IN in) (NP (DT a) (NN wiki) (NN website)))) At a certain moment of time I have a reference to (JJ single) and I want to get the NP node binding A single page. If I get it right, that NP is the parent of the node, A and page are its siblings and it has no children (?). When I try to use the .parent() method of a tree, I always get null. The API says that's because the implementation doesn't know how to determine the parent node. Another method of interest is .ancestor(int height, Tree root), but I don't know how to get the root of the node. In both cases, since the parser knows how to indent and group trees, it must know the "parent" tree, right? How can I get it? Thanks

  • "Collection was modified; enumeration operation may not execute." on form disposal.

    - by cyclotis04
    "Collection was modified; enumeration operation may not execute." appears to be a common error with foreach loops, but I can't figure mine out. I have two classes of forms. One is begun on startup, and a button creates new instances of the second form, and displays them. When I close the secondary forms, I get an InvalidOperationException. FirstForm.cs public partial class FirstForm : Form { SecondForm frmSecond; ... private void button1_Click(object sender, EventArgs e) { frmSecond= new SecondForm (); frmSecond.Show(); } } SecondForm.designer.cs partial class SecondForm { ... protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); // InvalidOperationException thrown here. } }

  • Write a file in UTF-8 using FileWriter (Java)?

    - by user1280970
    I have the following code however, I want it to write as a UTF-8 file to handle foreign characters. Is there a way of doing this, is there some need to have a parameter?

  • CakePHP and jQuery - Unobtrusive actions

    - by fortysixandtwo
    I'm trying to make an unobtrusive action for deleting bookmarks in CakePHP. Allthough it's working just fine, I suspect there must be a better way to do this. Could someone please point me in the right direction? function delete($id = null) { $ok = $this->Bookmark->delete($id); if($this->RequestHandler->isAjax()) { $this->autoRender = false; $this->autoLayout = false; $response = array('status' => 0, 'message' => 'Could not delete bookmark'); if($ok) { $response = array('status' => 1, 'message' => 'Bookmark deleted'); } $this->header('Content-Type: application/json'); echo json_encode($response); exit(); } // Request isn't AJAX, redirect. $this->redirect(array('action' => 'index')); }

  • In WPF using a ListView is there an elegant way to auto resize items?

    - by Justin
    I recently wrote, my first, WPF application that has a list of items that are polled from a web-serivce. The items are displayed/data-bound in a ListView via a GridView. A background thread periodically polls the web-serivce and updates the list. If, say, I had three items initially bound to the ListView that simply display a description and the three descriptions where something like: - ProjectA - ProjectB - ProjectC Later a new item is added with a description of 'AReallyReallyLongProjectName', I would end up with a list like: - ProjectA - ProjectB - ProjectC - AReallyR The GridViewColumn would not update it's width and would subsequently cut off any new items that extended the original width. I added this bit of code which forces the column to resize, but it just seems a little hacky. (Just seems weird to set a width just to set it back to nothing to force the resize) if(gridView != null) { foreach(var column in gridView.Columns) { if (double.IsNaN(column.Width) column.Width = column.ActualWidth; column.Width = double.NaN; } } Is there a better, more elegant solution, to accomplish this same thing?

  • Authorization in a more purely OOP style...

    - by noblethrasher
    I've never seen this done but I had an idea of doing authorization in a more purely OO way. For each method that requires authorization we associate a delegate. During initialization of the class we wire up the delegates so that they point to the appropriate method (based on the user's rights). For example: class User { private deleteMemberDelegate deleteMember; public StatusMessage DeleteMember(Member member) { if(deleteMember != null) { deleteMember(member); } } //other methods defined similarly... User(string name, string password) //cstor. { //wire up delegates based on user's rights. //Thus we handle authentication and authorization in the same method. } } This way the client code never has to explictly check whether or not a user is in a role, it just calls the method. Of course each method should return a status message so that we know if and why it failed. Thoughts?

  • What does the Facebook Ads API link_click metric indicate in adcampaignstats

    - by Michael Baird
    I would love to get a definitive answer or a glossary that defines the data returned from the Facebook ads api adcampaignstats. Specifically the difference between the actions and inline_actions. Below is the result for a dark post, and I like to know what the "link_click" metric in actions and inline_actions actually counts. i.e. Does this tell me that in total the campaign had 342 links clicked, or does "link_click" in "actions" and "inline_actions" indicate something else? act_{ad_account_id}/adcampaignstats?campaign_ids=[123456] { "is_completed": false, "social_unique_clicks": 0, "topline_id": 0, "unique_impressions": 0, "start_time": null, "campaign_id": 123456, "actions": { "offsite_conversion.registration": 14, "post_like": 2, "like": 5, "photo_view": 1, "link_click": 180 }, "clicks": 301, "inline_actions": { "comment": 0, "video_play": 0, "title_clicks": 0, "like": 10, "rsvp_maybe": 0, "post_like": 13, "photo_view": 0, "rsvp_yes": 0, "link_click": 162, "question_vote": 0 }, }

  • Changing a limited user account in XP fails

    - by javamonkey79
    I have the following: using System; using System.DirectoryServices.AccountManagement; public class ChangePassword { public static void Main() { PrincipalContext context = new PrincipalContext(ContextType.Machine); UserPrincipal user = UserPrincipal.FindByIdentity(context, "someLimitedAccount"); user.ChangePassword( "xxx", "zzz" ); } } This works just fine with administrator accounts, but seems to crash like so when I try to change limited accounts in XP: Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object. at ChangePassword.Main() Is what I am trying to do possible? If so, how? EDIT #1: I added the following: Console.WriteLine( "user: " + user ); Below this line: UserPrincipal user = UserPrincipal.FindByIdentity(context, "someLimitedAccount"); And I get this: user: It doesn't look like user is null when I print it, but then again I'm not really a .Net guy - I seem to remember this being expected behavior.

  • C++ and Scripting.Dictionary from scrrun.dll

    - by MaxFX
    Hello. I have some trouble with Scripting.Dictionary in C++. I'm trying to use interface IDictionary via smart pointer but methods of creating object don't work and I can't understand why. CoInitialize(NULL); IDictionaryPtr dict; dict.CreateInstance(__uuidof(Dictionary)); _variant_t num1 = 1; _variant_t num2 = 2; dict->Add(&num1, &num2); long i; dict->get_Count(&i); cout << i << "\n"; But method Add does not work and cout of elements in dictionary is always 0. How correct to use Scripting.Dictionary in that case. PS.: I'm getting Scripting interfaces by #import "scrrun.dll"

  • LinqToSql: insert instead of update

    - by Christina Mayers
    I am stuck with this problems for a long time now. Everything I try to do is insert a row in my DB if it's new information - if not update the existing one. I've updated many entities in my life before - but what's wrong with this code is beyond me (probably something pretty basic) I guess I can't see the wood for the trees... private Models.databaseDataContext db = new Models.databaseDataContext(); internal void StoreInformations(IEnumerable<EntityType> iEnumerable) { foreach (EntityType item in iEnumerable) { EntityType type = db.EntityType.Where(t => t.Room == iEnumerable.Room).FirstOrDefault(); if (type == null) { db.EntityType.InsertOnSubmit(item); } else { cur.Date = item.Date; cur.LastUpdate = DateTime.Now(); cur.End = item.End; } } } internal void Save() { db.SubmitChanges(); }

  • Handling duplicate nodes in XML

    - by JYelton
    Scenario: I am parsing values from an XML file using C# and have the following method: private static string GetXMLNodeValue(XmlNode basenode, string strNodePath) { if (basenode.SelectSingleNode(strNodePath) != null) return (basenode.SelectSingleNode(strNodePath).InnerText); else return String.Empty; } To get a particular value from the XML file, I generally pass the root node and a path like "parentnode/item" I recently ran into an issue where two nodes at the same document level share the same name. Question: What is the best way to get the values for duplicate-named nodes distinctly? My thought was to load all values matching the node name into an array and then using the array index to refer to them. I'm not sure how to implement that, though. (I'm not well-versed in XML navigation.)

  • C# implicit conversions

    - by Chris Boden
    Hello, I'm currently working on an application where I need to load data from an SQL database and then assign the retrieved values into the properties of an object. I'm doing this by using reflection since the property names and column names are the same. However, many of the properties are using a custom struct type that is basically a currency wrapper for the decimal type. I have defined an implicit conversion in my struct: public static implicit operator Currency(decimal d) { return new Currency(d); } This works fine when I use it in code. However, when I have this: foreach (PropertyInfo p in props) { p.SetValue(this, table.Rows[0][p.Name], null); } It throws an ArgumentException stating that it cannot convert from System.Decimal to Currency. I'm confused since it works fine in any other circumstance.

  • Actionbar scherlock is not refreshed when the orientation is changed

    - by SavasCinar
    I use Sherlock action bar in my application. I used "ifRoom|withText" feature in my menu. If I test my code in portrait mode, I can see only icon and if I rotate orientation to landscape, still I see only icon. On the other hand, if I run with landscape, I can see text and icon on portrait and landscape. This means that When the screen is rotated, action bar is not refreshed. How can I fix? In menu, I have android:showAsAction="ifRoom|withText" Also I used this line in my manifest file to fixed android:configChanges="keyboardHidden|orientation|screenSize" but it didn't work. And I run my code android 2.3 Also I used fragment in my activity, FragmentManager fm = getSupportFragmentManager(); ft = fm.beginTransaction(); mFragment1 = fm.findFragmentByTag("f1"); if (mFragment1 == null) { mFragment1 = new MenuFragment(); ft.add(mFragment1, "f1"); } ft.commit();

The plugin can be found here: http://www.webdesignbeach.com/beachbar/ajax-fancy-captcha-jquery-plugin What I have tried: in the controller: public function index($slug = null, $capture = false) { if($capture AND $capture =="get_capture"){ $rand = rand(0,4); $_SESSION['captcha'] = $rand; echo $rand; die; } if (!empty($this->data) && $_POST['captcha'] == $_SESSION['captcha']) { .... save the post } } in the view: $selectURL = " $(function() { $('.ajax-fc-container').captcha({ borderColor: 'silver', captchaDir: 'http://localhost/img/capture', url: 'http://localhost/contacts/index/contacts/get_capture', formId: 'MessageIndexForm', }); });"; $this->Html->scriptBlock($selectURL, array('inline' => false)); also I have tried with url: 'http://localhost/js/capture.php' which is the original file coming with the plugin but still not working.

  • ASp.Net Mvc 1.0 Dynamic Images Returned from Controller taking 154 seconds+ to display in IE8, firef

    - by julian guppy
    I have a curious problem with IE, IIS 6.0 dynamic PNG files and I am baffled as to how to fix.. Snippet from Helper (this returns the URL to the view for requesting the images from my Controller. string url = LinkBuilder.BuildUrlFromExpression(helper.ViewContext.RequestContext, helper.RouteCollection, c = c.FixHeight(ir.Filename, ir.AltText, "FFFFFF")); url = url.Replace("&", "&"); sb.Append(string.Format("<removed id=\"TheImage\" src=\"{0}\" alt=\"\" /", url)+Environment.NewLine); This produces a piece of html as follows:- img id="TheImage" src="/ImgText/FixHeight?sFile=Images%2FUser%2FJulianGuppy%2FMediums%2Fconservatory.jpg&backgroundColour=FFFFFF" alt="" / brackets missing because i cant post an image... even though I dont want to post an image I jsut want to post the markup... sigh Snippet from Controller ImgTextController /// <summary> /// This function fixes the height of the image /// </summary> /// <param name="sFile"></param> /// <param name="alternateText"></param> /// <param name="backgroundColour"></param> /// <returns></returns> [AcceptVerbs(HttpVerbs.Get)] public ActionResult FixHeight(string sFile, string alternateText, string backgroundColour) { #region File if (string.IsNullOrEmpty(sFile)) { return new ImgTextResult(); } // MVC specific change to prepend the new directory if (sFile.IndexOf("Content") == -1) { sFile = "~/Content/" + sFile; } // open the file System.Drawing.Image img; try { img = System.Drawing.Image.FromFile(Server.MapPath(sFile)); } catch { img = null; } // did we fail? if (img == null) { return new ImgTextResult(); } #endregion File #region Width // Sort out the width from the image passed to me Int32 nWidth = img.Width; #endregion Width #region Height Int32 nHeight = img.Height; #endregion Height // What is the ideal height given a width of 2100 this should be 1400. var nIdealHeight = (int)(nWidth / 1.40920096852); // So is the actual height of the image already greater than the ideal height? Int32 nSplit; if (nIdealHeight < nHeight) { // Yes, do nothing, well i need to return the iamge... nSplit = 0; } else { // rob wants to not show the white at the top or bottom, so if we were to crop the image how would be do it // 1. Calculate what the width should be If we dont adjust the heigt var newIdealWidth = (int)(nHeight * 1.40920096852); // 2. This newIdealWidth should be smaller than the existing width... so work out the split on that Int32 newSplit = (nWidth - newIdealWidth) / 2; // 3. Now recrop the image using 0-nHeight as the height (i.e. full height) // but crop the sides so that its the correct aspect ration var newRect = new Rectangle(newSplit, 0, newIdealWidth, nHeight); img = CropImage(img, newRect); nHeight = img.Height; nWidth = img.Width; nSplit = 0; } // No, so I want to place this image on a larger canvas and we do this by Creating a new image to be the size that we want System.Drawing.Image canvas = new Bitmap(nWidth, nIdealHeight, PixelFormat.Format24bppRgb); Graphics g = Graphics.FromImage(canvas); #region Color // Whilst we can set the background colour we shall default to white if (string.IsNullOrEmpty(backgroundColour)) { backgroundColour = "FFFFFF"; } Color bc = ColorTranslator.FromHtml("#" + backgroundColour); #endregion Color // Filling the background (which gives us our broder) Brush backgroundBrush = new SolidBrush(bc); g.FillRectangle(backgroundBrush, -1, -1, nWidth + 1, nIdealHeight + 1); // draw the image at the position var rect = new Rectangle(0, nSplit, nWidth, nHeight); g.DrawImage(img, rect); return new ImgTextResult { Image = canvas, ImageFormat = ImageFormat.Png }; } My ImgTextResult is a class that returns an Action result for me but embedding the image from a memory stream into the response.outputstream. snippet from my ImageResults /// <summary> /// Execute the result /// </summary> /// <param name="context"></param> public override void ExecuteResult(ControllerContext context) { // output context.HttpContext.Response.Clear(); context.HttpContext.Response.ContentType = "image/png"; try { var memStream = new MemoryStream(); Image.Save(memStream, ImageFormat.Png); context.HttpContext.Response.BinaryWrite(memStream.ToArray()); context.HttpContext.Response.Flush(); context.HttpContext.Response.Close(); memStream.Dispose(); Image.Dispose(); } catch (Exception ex) { string a = ex.Message; } } Now all of this works locally and lovely, and indeed all of this works on my production server BUT Only for Firefox, Safari, Chrome (and other browsers) IE has a fit and decides that it either wont display the image or it does display the image after approx 154seconds of waiting..... I have made sure my HTML is XHTML compliant, I have made sure I am getting no Routing errors or crashes in my event log on the server.... Now obviously I have been a muppet and have done something wrong... but what I cant fathom is why in development all works fine, and in production all non IE browsers also work fine, but IE 8 using IIS 6.0 production server is having some kind of problem in returning this PNG and I dont have an error to trace... so what I am looking for is guidance as to how I can debug this problem.

  • Returning Json object from controller action to jQuery

    - by PsychoCoder
    I'm attempting to get this working properly (2 days now). I'm working on a log in where I'm calling the controller action from jQuery, passing it a JSON object (utilizing json2.js) and returning a Json object from the controller. I'm able to call the action fine, but instead of being able to put the response where I want it it just opens a new window with this printed on the screen: {"Message":"Invalid username/password combination"} And the URL looks like http://localhost:13719/Account/LogOn so instead of calling the action and not reloading the page it's taking the user to the controller, which isn't good. So now for some code, first the controller code [HttpPost] public ActionResult LogOn(LogOnModel model, string returnUrl = "") { if (ModelState.IsValid) { var login = ObjectFactory.GetInstance<IRepository<PhotographerLogin>>(); var user = login.FindOne(x => x.Login == model.Username && x.Pwd == model.Password); if (user == null) return Json(new FailedLoginViewModel { Message = "Invalid username/password combination" }); else { if (!string.IsNullOrEmpty(returnUrl)) return Redirect(returnUrl); else return RedirectToAction("Index", "Home"); } } return RedirectToAction("Index", "Home"); } And the jQuery code $("#signin_submit").click(function () { var login = getLogin(); $.ajax({ type: "POST", url: "../Account/LogOn", data: JSON.stringify(login), dataType: 'json', contentType: 'application/json; charset=utf-8', error: function (xhr) { $("#message").text(xhr.statusText); }, success: function (result) { } }); }); function getLogin() { var un = $("#username").val(); var pwd = $("#password").val(); var rememberMe = $("#rememberme").val(); return (un == "") ? null : { Username: un, Password: pwd, RememberMe: rememberMe }; } In case you need to see the actual login form here that is as well <fieldset id="signin_menu"> <div> <span id="message"></span> </div> <% Html.EnableClientValidation(); %> <% using (Html.BeginForm("LogOn", "Account", FormMethod.Post, new { @id = "signin" })) {%> <% ViewContext.FormContext.ValidationSummaryId = "valLogOnContainer"; %> <%= Html.LabelFor(m => m.Username) %> <%= Html.TextBoxFor(m => m.Username, new { @class = "inputbox", @tabindex = "4", @id = "username" })%><%= Html.ValidationMessageFor(m => m.Username, "*")%> <p> <%= Html.LabelFor(m=>m.Password) %> <%= Html.PasswordFor(m => m.Password, new { @class = "inputbox", @tabindex = "5", @id = "password" })%><%= Html.ValidationMessageFor(m => m.Password, "*")%> </p> <p class="remember"> <input id="signin_submit" value="Sign in" tabindex="6" type="submit"/> <%= Html.CheckBoxFor(m => m.RememberMe, new { @class = "inputbox", @tabindex = "7", @id = "rememberme" })%> <%= Html.LabelFor(m => m.RememberMe) %> <p class="forgot"> <a href="#" id="forgot_password_link" title="Click here to reset your password.">Forgot your password?</a> </p> <p class="forgot-username"> <a href="#" id="forgot_username_link" title="Fogot your login name? We can help with that">Forgot your username?</a> </p> </p> <%= Html.ValidationSummaryJQuery("Please fix the following errors.", new Dictionary<string, object> { { "id", "valLogOnContainer" } })%> <% } %> </fieldset> The login form is loaded on the main page with <% Html.RenderPartial("LogonControl");%> Not sure if that has any bearing on this or not but thought I'd mention it. EDIT: The login form is loaded similar to the Twitter login, click a link and the form loads with the help of jQuery & CSS
