  • Using lock(obj) inside a recursive call

    - by Amby
    As per my understanding a lock is not released until the runtime completes the code block of the lock(obj) ( because when the block completes it calls Monitor.Exit(obj). With this understanding i am not able to understand the reason behind the behaviour of the following code. private static string obj = ""; private static void RecurseSome(int number) { Console.WriteLine(number); lock (obj) { RecurseSome(++number); } } //Call: RecurseSome(0) //Output: 0 1 2 3...... stack overflow exception There must be some concept that i am missing. Please help.

  • IE7 & 8 not fireing jQuery click events for elements appended inside a table

    - by Keith
    I have an IE bug that I'm not sure how to fix. Using jQuery I'm dynamically moving a menu to appear on an element on mouseover. My code (simplified) looks something like this: $j = jQuery.noConflict(); $j(document).ready(function() { //do something on the menu clicks $j('div.ico').click(function() { alert($j(this).parent().html()); }); setUpActions('#tableId', '#menuId'); }); //on mouseover set up the actions menu to appear on mouseover function setUpActions(tableSelector, menuSelector) { $j(tableSelector + ' div.test').mouseover(function() { //note that append will move the underlying //DOM element with all events from it's old //parent to the end of this one. $j(this).append($j(menuSelector).show()); }); } This menu doesn't seem to register events correctly for the menu after it's been moved in IE7, IE8 and IE8-as-IE7 (yeah MS, that's really a 'new rendering engine' in IE8, we all believe you). It works as expected in everything else. You can see the behaviour in a basic demo here. In the demo you can see two examples of the issue: The image behind the buttons should change on hover (done with a CSS :hover selector). It works on the first mouseover but then persists. The click event doesn’t fire – however with the dev tools you can manually call it and it is still subscribed. You can see (2) in IE8's dev tools: Open page in IE8 Open dev tools Select "Script" tab and "Console" sub-tab Type: $j('#testFloat div.ico:first').click() to manually call any subscribed events There will be an alert on the page This means that I'm not losing the event subscriptions, they're still there, IE's just not calling them when I click. Does anyone know why this bug occurs (other than just because of IE's venerable engine)? Is there a workaround? Could it be something that I'm doing wrong that just happens to work as expected in everything else?

  • Adding on touch event to images inside gridview

    - by Steve
    I have a gridview where each item has a image and a textview (an app), i added the onItemClick to the gridview in order to launch the app, i also removed the orange selection and made selector in xml so when pressed the text would change to grey and on release it would return to white. My problem is that i need the image to apply an alpha value when pressed and restore the previous alpha on release i tested a lot of ways and none did worked correctly. I came close with the updated answer from the autor of the question: How to set alpha value for drawable in a StateListDrawable?, but some how the state pressed never gets called, i don´t know if this is because i am using the onitemClick to launch the app or not. Also i since i can´t define the alpha on imageview xml i don´t know what else to do Any help will be appreciated

  • Appending html code to a section inside a dialog window isn't working in IE6

    - by user338413
    I'm using jQuery's validation on a form. When the form is validated, I'm using a submitHandler to fill a dialog with data from the form then I open the dialog to display it. Works great except for in IE6. Nothing displays. I've tried initializing the dialog before and after running the validation code but neither makes a difference. Here's the validation code: $("#acct").validate({ ... submitHandler: function() { fillVerificationDialog(); $("#verification_dialog").dialog('open'); return false; } }); Here's the fillVerificationDialog: function fillVerificationDialog() { $("#dialog-data").empty(); $("<span class='label'>").text("First Name: ").appendTo("#dialog-data"); $("<span class='value'>").text($("#firstname").val()).appendTo("#dialog-data"); $("<br/>").appendTo("#dialog-data"); ... }

  • Creating a new Guid inside a code snippet using c#

    - by Rob
    I want to make an intellisense code snippet using Ctl K + Ctl X that actually executes code when it runs... for example, I would like to do the following: <![CDATA[string.Format("{MM/dd/yyyy}", System.DateTime.Now);]]> But rather than giving me that string value, I want the date in the format specified. Another example of what I want is to create a new Guid but truncate to the first octet, so I would want to use a create a new Guid using System.Guid.NewGuid(); to give me {798400D6-7CEC-41f9-B6AA-116B926802FE} for example but I want the value: 798400D6 from the code snippet. I'm open to not using an Intellisense Code Snippet.. I just thought that would be easy.

  • Can I query inside a SQLite Transaction?

    - by CSharperWithJava
    I'm using the SQLite3 database system in the Android library. I need to execute a query during a transaction to see if there is a similar entry already there. If there is, I have to perform some other logic and adjustments before I add a new row. Can I execute a query within a transaction and get the result back immediately?

I found a similar question here but did not get it either...

  • Using scope, defined in parent model, inside it's child (STI pattern)

    - by Anton
    I implement a class hierarchy using STI pattern class A scope :aaa, where([someField]:[someValue]) end class B < A end The problem is that when I try to call something like: B.limit(5).aaa => SELECT "[table]".* FROM "[table]" WHERE "[table]"."type" IN ('A') AND ([someField] = [someValue]) LIMIT 5 So I am getting 5 objects of type A, which satisfies scope :aaa But I need to do the same with rows where type = "B" Is there any way to use scopes from parent, without redifinning it in childs in STI pattern? Thanks in advance EDITED I just discussed it with my frind and he showed me one important thing. A in not the root class of STI. IN fact whole hierarchy looks like class O < ActiveRecord::Base end class A < O scope ..... ..... end class B < A end maybe the reason is in hierarchy itself?...

  • Perl standard input with argument inside Bash

    - by neversaint
    I want to have such pipe in bash #! /usr/bin/bash cut -f1,2 file1.txt | myperl.pl foo | sort -u Now in myperl.pl it has content like this my $argv = $ARG[0] || "foo"; while (<>) { chomp; if ($argv eq "foo") { # do something with $_ } else { # do another } } But why the Perl script can't recognize the parameter passed through bash? Namely the code break with this message: Can't open foo: No such file or directory at myperl.pl line 15. What the right way to do it so that my Perl script can receive standard input and parameter at the same time?

  • Use of properties vs backing-field inside owner class

    - by whatispunk
    I love auto-implemented properties in C# but lately there's been this elephant standing in my cubicle and I don't know what to do with him. If I use auto-implemented properties (hereafter "aip") then I no longer have a private backing field to use internally. This is fine because the aip has no side-effects. But what if later on I need to add some extra processing in the get or set? Now I need to create a backing-field so I can expand my getters and setters. This is fine for external code using the class, because they won't notice the difference. But now all of the internal references to the aip are going to invoke these side-effects when they access the property. Now all internal access to the once aip must be refactored to use the backing-field. So my question is, what do most of you do? Do you use auto-implemented properties or do you prefer to always use a backing-field? What do you think about properties with side-effects?

  • Silverlight Binding: User controls inside datagrid.

    - by Eric
    I have a DataGrid in my silverlight app that has a few columns. A couple basic columns bound with no issues. One column has a UserControl in it and the XAML is as follows: <data:DataGridTemplateColumn Header="" CanUserSort="True" Width="107"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <local:StaticPageEnlistment EnlistmentName="{Binding SiteName}" Width="400" Height="150"/> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> </data:DataGridTemplateColumn> So I have a public property that's a string called EnlistmentName that I have bound to the SiteName value. I use this same "{Binding SiteName}" in all my other colums with no issues, why can't the user control accept the same binding string?

  • HTML tag closes when inside a condition

    - by Malharhak
    I'm having a little problem with jade. Here is the following code : each user in users - if (user.valid == 1) tr(style="color:green;") - else tr(style="color:red;") td = user.mail td = user.lastIp td = user.token td = user.valid My problem is that the tds are created only in the else case. if the if (user.valid == 1) is true, then it creates an empty tr. Is there a way I can create my tr with this condition, and then only fill them ? Thanks :)

  • Drupal, Lightbox: cannot edit the content inside

    - by Patrick
    hi, I'm using Drupal and Lightbox module to display the content of articles in this website: donatellabernardi.ch/drupal if you click on an article the lightbox is displayed. However I have 2 problems with it: 1) I cannot use the libraries such as the tooltip library qTip from it. (If you move the mouse over the balls, you'll see the tooltips) 2) I cannot invert the title with the balls (tags), because it seems that the template of the node in the lightbox is not controlled by my theme. I tried also to change the node template (in the drupal root folder), swapping title and meta data but it didn't work. thanks

  • How to parse the AndroidManifest.xml file inside an .apk package

    - by jnorris
    This file appears to be in a binary XML format. What is this format and how can it be parsed programmatically (as opposed to using the aapt dump tool in the SDK)? This binary format is not discussed in the in the documentation here: http://developer.android.com/guide/topics/manifest/manifest-intro.html Note: I want to access this information from outside the Android environment, preferably from Java.

  • Inserting Row in Table inside Form tag autosubmitting in firefox/chrome

    - by user1861489
    I have a form that will have dynamic elements inserted with javascript and am experiencing some strange behavior. When I click the button to add another element to the table in the form, it adds the element but seems to to a form post immediately (without intending to submit the form yet) I have created a simplified example of the page that has the same behavior. the first table element is created on page load and subsequent elements are added when clicking on the button. this form works successfully in IE. does anyone have an idea of how to prevent this behavior? here is the code sample. <!DOCTYPE html> <html> <head> <title>Test Creating Form</title> <meta http-equiv="Content-type" content="text/html;charset=UTF-8"> <style type="text/css"> td{font-family:verdana;} </style> <script type="text/javascript"> var counter = 0; function makeTitle(title){ if(counter){ title += " " + counter; } counter++; var tbl = document.getElementById('tbl'); var tr = tbl.insertRow(-1) var td1 = tr.insertCell(-1); td1.innerHTML = title; } function load1(){ makeTitle('Primary Specimen'); } </script> </head> <body onload="load1();"> <form action="formtest.htm" method="post" name="testForm" id="testForm"> <table id="tbl" border="1"></table> <button onclick="makeTitle('Alternate Specimen')" id="clone" >Add Another Specimen</button> </form> </body> </html>

  • A public struct inside a class

    - by Koning Baard
    I am new to C++, and let's say I have two classes: Creature and Human: /* creature.h */ class Creature { private: public: struct emotion { /* All emotions are percentages */ char joy; char trust; char fear; char surprise; char sadness; char disgust; char anger; char anticipation; char love; }; }; /* human.h */ class Human : Creature { }; And I have this in my main function in main.cpp: Human foo; My question is: how can I set foo's emotions? I tried this: foo->emotion.fear = 5; But GCC gives me this compile error: error: base operand of '-' has non-pointer type 'Human' This: foo.emotion.fear = 5; Gives: error: 'struct Creature::emotion' is inaccessible error: within this context error: invalid use of 'struct Creature::emotion' Can anyone help me? Thanks P.S. No I did not forget the #includes
