  • 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

  • Accessing FacesContext from Web Service

    - by scriptmonster
    I'm developing a Web Service which will be called by clients which are written by me. In the web service I need to use application-wide objects which eases the load of application on the system. I have implemented my application-wide objects as shown in this question. I can use my object in a jsf page with no problem as follows. MyObject mo = (MyObject) FacesContext.getCurrentInstance().getExternalContext().getApplicationMap().get("MyObjectsName"); But when it comes to use it in a Web Service Request FacesContext.getCurrentInstance() returns null. Is there any way to use the FacesContext in a web service.

  • "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. } }

  • Java: Line appears when using AffineTransform to scale image

    - by Malakim
    Hi, I'm having a problem with image scaling. When I use the following code to scale an image it ends up with a line either at the bottom or on the right side of the image. double scale = 1; if (scaleHeight >= scaleWidth) { scale = scaleWidth; } else { scale = scaleHeight; } AffineTransform af = new AffineTransform(); af.scale(scale, scale); AffineTransformOp operation = new AffineTransformOp(af, AffineTransformOp.TYPE_NEAREST_NEIGHBOR); BufferedImage bufferedThumb = operation.filter(img, null); The original image is here: http://tinyurl.com/yzv6r7h The scaled image: http://tinyurl.com/yk6e8ga Does anyone know why the line appears? Thanks!

  • 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.

  • Load NSAttributedString from File

    - by Wayfarer
    Is there a way to have some sort of rich text in a file, and load the file into an NSAttributedString? I looked into loading a .rtf file into an NSAttributed String: NSString *filePathFooter = [[NSBundle mainBundle] pathForResource:kFooterFileName ofType:@"rtf"]; NSError *error = nil; NSAttributedString *string = [[NSAttributedString alloc] initWithFileURL:[NSURL URLWithString:filePathFooter] options:nil documentAttributes:NULL error:&error]; But this leaves me with: Error Domain=NSCocoaErrorDomain Code=258 "The operation couldn’t be completed. (Cocoa error 258.)" Is there a way to do this?

  • 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(); }

  • Cocoa - NSFileManager removeItemAtPath Not Working

    - by Kevin
    Hey there everyone, I am trying to delete a file, but somehow nsfilemanager will not allow me to do so. I do use the file in one line of code, but once that action has been ran, I want the file deleted. I have logged the error code and message and I get error code: 4 and the message: "text.txt" could not be removed Is there a way to fix this error "cleanly" (without any hacks) so that apple will accept this app onto their Mac App Store? EDIT: This is what I am using: [[NSFileManager defaultManager] removeItemAtPath:filePath error:NULL]; Thanks, kevin

  • What can I do about a SQL Server ghost FK constraint?

    - by rcook8601
    I'm having some trouble with a SQL Server 2005 database that seems like it's keeping a ghost constraint around. I've got a script that drops the constraint in question, does some work, and then re-adds the same constraint. Normally, it works fine. Now, however, it can't re-add the constraint because the database says that it already exists, even though the drop worked fine! Here are the queries I'm working with: alter table individual drop constraint INDIVIDUAL_EMP_FK ALTER TABLE INDIVIDUAL ADD CONSTRAINT INDIVIDUAL_EMP_FK FOREIGN KEY (EMPLOYEE_ID) REFERENCES EMPLOYEE After the constraint is dropped, I've made sure that the object really is gone by using the following queries: select object_id('INDIVIDUAL_EMP_FK') select * from sys.foreign_keys where name like 'individual%' Both return no results (or null), but when I try to add the query again, I get: The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "INDIVIDUAL_EMP_FK". Trying to drop it gets me a message that it doesn't exist. Any ideas?

  • 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.)

  • Why won't this SQL CAST work?

    - by Kev
    I have a nvarchar(50) column in a SQL Server 2000 table defined as follows: TaskID nvarchar(50) NULL I need to fill this column with some random SQL Unique Identifiers (I am unable to change the column type to uniqueidentifier). I tried this: UPDATE TaskData SET TaskID = CAST(NEWID() AS nvarchar) but I got the following error: Msg 8115, Level 16, State 2, Line 1 Arithmetic overflow error converting expression to data type nvarchar. I also tried: UPDATE TaskData SET TaskID = CAST(NEWID() AS nvarchar(50)) but then got this error: Msg 8152, Level 16, State 6, Line 1 String or binary data would be truncated. I don't understand why this doesn't work but this does: DECLARE @TaskID nvarchar(50) SET @TaskID = CAST(NEW() AS nvarchar(50)) I also tried CONVERT(nvarchar, NEWID()) and CONVERT(nvarchar(50), NEWID()) but got the same errors.

  • Index on column with only 2 distinct values

    - by Will
    I am wondering about the performance of this index: I have an "Invalid" varchar(1) column that has 2 values: NULL or 'Y' I have an index on (invalid), as well as (invalid, last_validated) Last_validated is a datetime (this is used for a unrelated SELECT query) I am flagging a small amount of items (1-5%) of rows in the table with this as 'to be deleted'. This is so when i DELETE FROM items WHERE invalid='Y' it does not perform a full table scan for the invalid items. A problem seems to be, the actual DELETE is quite slow now, possibly because all the indexes are being removed as they are deleted. Would a bitmap index provide better performance for this? or perhaps no index at all?

  • 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

Another problem with Firefox is that requests to /Home/Refresh are made every second not every 5 seconds. I noticed that after I clear Firefox cache the script works well first time button1 is pressed, but after that it doesn't work. I would be grateful for helpful suggestions.

  • Toottip data issue in jquery flot

    - by Muhammad
    I am using Jquery plot.Every thing is working except tooltip data. Total data shown on a line is 190 which is equal to total published PLUS total unpublished.Total Published is 51 which is shown in tooltip.Now the other portion of tooltip shows 190 instead of 190-51 = 139 here is my code var options1 = { series: {stack: stack, lines: { show: lines, fill: false, steps: steps }, bars: { show: bars, barWidth: 0.4 }, points: { show: true} }, grid: { hoverable: true //IMPORTANT! this is needed for tooltip to work }, tooltip: true, tooltipOpts: { content: "%s : %y", shifts: { x: -60, y: 25 } }, legend:{'position':'ne','show':true,'margin':[-3, -20],'backgroundOpacity':0.1, 'noColumns': 4, 'container': null}, xaxis: {ticks: dest4 ,}, }; what i should do with this line to show exact data content: "%s : %y",

  • JScript JSON Object Check

    - by George
    I'm trying to check if json[0]['DATA']['name'][0]['DATA']['first_0'] exists or not when in some instances json[0]['DATA']['name'] contains nothing. I can check json[0]['DATA']['name'] using if (json[0]['DATA']['name'] == '') { // DOES NOT EXIST } however if (json[0]['DATA']['name'][0]['DATA']['first_0'] == '' || json[0]['DATA']['name'][0]['DATA']['first_0'] == 'undefined') { // DOES NOT EXIST } returns json[0]['DATA']['name'][0]['DATA'] is null or not an object. I understand this is because the array 'name' doesn't contain anything in this case, but in other cases first_0 does exist and json[0]['DATA']['name'] does return a value. Is there a way that I can check json[0]['DATA']['name'][0]['DATA']['first_0'] directly without having to do the following? if (json[0]['DATA']['name'] == '') { if (json[0]['DATA']['name'][0]['DATA']['first_0'] != 'undefined') { // OBJECT EXISTS } }
