• Jquery UI Autocomplete widget conflict qith jqeury.menu widget - how can I solve it?

  - by JK

  My app already has a completed menu using jquery.menu.js found at http://wiki.jqueryui.com/Menu. I'm now also trying to add the jquery autocomplete widget from jquery ui 1.8.1 - but both of these have a .menu() function that conflicts with each other. If I put jquery-ui-1.8.1.custom.js first in the head, then autocomplete works but the menu does not. If I put jquery-menu.js first in the head, then the menu works but autocomplete doesnt. Is there a way to solve this without editing either plugin? (If I edit, I will probably lose those changes the next time either plugin is upgraded)

• keeping xmphp bot always online

  - by Gunjan

  I created a simple xmpp bot in PHP which connects to google talk server. I basically modified the cli_longrun example. When I run the script in browser the bot comes online and stays online for a while even after I close the tab on which the script was running (as it is just an infinite loop listening for events on the stream). But after a while the bot becomes offline. The question is how do I keep the bot always online. One way I can think of is to run a cron that would disconnect the earlier one and start a new session. But is there a better approch?

• Skinning WinAPI Controls

  - by Brad

  If you've ever seen an application in the Adobe Creative Suite 5 (CS5), you may have noticed that it doesn't look like the native Windows GUI.. They have modified it to have a different look to it. Where would someone begin to make an application that has a custom skin? CS5 uses the Adobe Source library for it's widget/control management, so I tried downloading and compiling the Adobe Source Library to see if I could make a nice skinned app like Photoshop CS5, but after finally getting it to compile and tested it, I realized the library was only for managing widgets and not skinning the GUI, like CS5 has. Where would I begin to make a nice skinned program like Adobe Cs5 applications? Can anyone point me in the right direction? Do I simply use the WM_PAINT Message from WinAPI and render my own widgets using openGL or something?

• WPF DependencyProperty event before content changed

  - by morsanu

  First I will explain the context of the problem, because you might be able to point me in a better direction. I need to implement a undo-redo like system on an object. The object has a series of dependency properties. Some are double, int, string but some are also of DependencyObject type. I need to save the value of the property before it is changed, and for this I added the CoerceValueCallback. public static readonly DependencyProperty MyBackgroundProperty = DependencyProperty.Register("MyBackground", typeof(MyCustomizableBackground), typeof(MyComponent), new UIPropertyMetadata(default(MyCustomizableBackground), null, new CoerceValueCallback(OnPropertyChanged))); In OnPropertyChanged I save the value before it's changed. MyCustomizableBackground is the DependencyObject that has also some dependency properties. The problem is that in this case, where I have a custom object as a property, the OnPropertyChanged method isn't triggered, but when I have a common type, it is triggered.

• XMLHttpRequest inside an object: how to keep the reference to "this"

  - by Julien

  I make some Ajax calls from inside a javascript object.: myObject.prototye = { ajax: function() { this.foo = 1; var req = new XMLHttpRequest(); req.open('GET', url, true); req.onreadystatechange = function (aEvt) { if (req.readyState == 4) { if(req.status == 200) { alert(this.foo); // reference to this is lost } } } }; Inside the onreadystatechange function, this does not refer to the main object anymore, so I don't have access to this.foo. Ho can I keep the reference to the main object inside XMLHttpRequest events?

• Rails override validator message

  - by Anand

  Hi, I have a site thats served in 2 flavours, English and French. Here's some code app/views/user/register.html.erb ----------------- <% form_for .....> <%= f.text_field :first_name %> <% end %> app/models/user.rb ------------------ class User < ActiveRecord::Base validates_presence_of :first_name end Now to display the error message in case if the site is being served in the French version, I have app/config/locales/fr.yml ------------------------- activerecord: errors: messages: empty: "ne peut pas être vide" So if someone does not fill in a first name, the validator takes the name of the field and appends the custom message for empty clause giving "First name ne peut pas être vide" which is incorrect, coz 'First name' in French is 'Prénom', hence it should be "Prénom ne peut pas être vide" Please can someone suggest a way of achieving the desired result.

• In an ExpandableListView, how can I show one additional line at the end of the child results?

  - by fiXedd

  I have created a custom ExpandableListAdapter and everything works properly. What I'd like to be able to do is in each of the groups add a different type of child to the end. I have tried adding 1 to the getChildrenCount() number and then testing isLastChild in the getChildView() method, but that doesn't seem to work. If a group has three children what I have working looks like this: Group NormalChild NormalChild NormalChild But I'd really like something like this: Group NormalChild NormalChild NormalChild AlternateChild The idea being that the AlternateChild could be a link to more info about the group. Any Ideas? EDIT: ListView has addFooterView() which will allow you to add a footer to a whole ListView... wonder how to add them to the ExpandableListView's children, or if it's even possible

• WPF/MVVM: Reshaping/Binding data on a DataGrid to a PivotGrid layout ?

  - by msfanboy

  Hello, I do not want to use 3rd party controls because I would have to buy a suite for justing using one control... So is there any chance I can arrange 3 entities: Subject, Grade and Pupil in that way on a simple DataGrid to show Pivot data like: ...........Math....Sports.... M.Kramer...A.......C......... B.Jonson...D.......A......... Does the binding for example work on the RowHeader with properties of a custom object/entity ? And would sorting destroy the whole relations between the entities ? You ever tried to do something like that?

• Storing Templates and Object-Oriented vs Relational Databases

  - by syrion

  I'm designing some custom blog software, and have run into a conundrum regarding database design. The software requires that there be multiple content types, each of which will require different entry forms and presentation templates. My initial instinct is to create these content types as objects, then serialize them and store them in the database as JSON or YAML, with the entry forms and templates as simple strings attached to the "contentTypes" table. This seems cumbersome, however. Are there established best practices for dealing with this design? Is this a use case where I should consider an object database? If I should be using an object database, which should I consider? I am currently working in Python and would prefer a capable Python library, but can move to Java if need be.

• Is this part of MVC in .NET?

  - by 4thSpace

  I have a .NET MVC winform app. I've created an AppDelegate class that handles application startup and shutdown...for now (it might do more later). Winform apps have a Program.cs file that does some app initialization, starts the message pump and creates the first form. In my app, the first form is AppDelegate, which isn't really a form but is forced that way by Application.Run(). AppDelegate does any further app initialization and starts the first Controller, which then initializes any child controllers (these then create their views). I don't consider events occuring in Program.cs and AppDelegate as part of the MVC. Conceptually, what would these be called?

• Silverlight 3-4 reference kind (e-)book.

  - by Bubba88

  Hello! I'm looking for a source of information about Microsoft Silverlight to begin practically efficient programming custom functionality applications. I want to pretend just for now that I don't need any ideologically correct refresher (SL tips, top patterns, VS tutorials :) and etc.). Basically, what I want is a reference kind e-book, where I could find any practically relevant info outlined in a minimalistic manner. If you do remember something fitting the above description, I ask you to give me a hint. Thank you very much!

• VBS Script for modifying multi-value Active Directory display specifier

  - by sh-beta

  Following the howto Extending the Active Directory Schema To Track Custom Info I'm able to setup a single-value schema attribute that is easily changeable via a context menu in ADUC. Multi-value schema attributes get considerably more complicated. Say (for the sake of argument) my value is "Projects" and each user may be a list as many projects as necessary. Following is a sad little script that will set Project to a single value: Dim oproject Dim oUser1 Dim temp1 Set oproject = Wscript.Arguments Set oUser1 = GetObject(oproject(0)) temp1 = InputBox("Project: " & oUser1.project & vbCRLF & vbCRLF & "Project") if temp1 <> "" then oUser1.Put "project",temp1 oUser1.SetInfo Set oUser1 = Nothing Set oproject = Nothing Set temp1 = Nothing WScript.Quit How can I modify this to allow, assign, and modify multiple values?

• reference symbols on the main timeline

  - by vasion

  this is one of those upsurdly basic questions for which google does not work. I have usually dispatched events from my classes and dealt with the user interface in the document class. But now i want to separate all the UI in a separate class, accessible by other classes. I have added it as a child to the main/document class, but how do i reference the main class without going through parent.parent shananigans? edit. one more thing i remembered. Some of my UI elements are not programatically added.

• Automatically Loading XIB for UITableViewController

  - by ACBurk

  Ran into something interesting, want to know if I'm doing something wrong or if this is the correct behavior. I have a custom UITableViewController. I ASSUMED (first mistake) that if you initialize as such: [[CustomTableController alloc] init]; it would automatically load from a XIB of the same name, CustomTableController.xib, if it is in the same directory and such. HOWEVER This does not work; doesn't load the XIB. BUT, if I change the parent class of my controller from 'UITableViewController' to 'UIViewController', EVERYHTING WORKS FINE! Calling: [[CustomTableController alloc] init]; loads the controller and view from my xib. Am I doing something wrong? Is this a bug? Expected behavior?

• How can I store all the properties of a class in an array of objects?

  - by Richard77

  Hello, Let's say I've a class myClass which has few properties, such as property1, property2, perperty3, etc. Now, I'd like to populate an array with each of those properties so that, I can access each of them through its index. Is there an automatic way of doing so? Here's an example from SportsStore (Pro ASPN.NET MVC/Steve Sanderson/Apress) on how to gather all the active controllers in the the 'Assembly'. var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes() where typeof(IController).IsAssignableFrom(t) select t; foreach(Type t in controllerTypes) //Do something I wonder if there is some thing like the one above I can use to collect (only) properties of a class and store them in a array, no matter each one's type value (int, string, or custom type) I hope I was able to express myself clearly. Otherwise I can amend the text. Thanks for helping.

• In LaTeX, how can one add a header/footer in the document class Letter?

  - by Brian M. Hunt

  In LaTeX, how can one create a document using the Letter documentclass, but with customized headers and footers? Typically I would use: \usepackage{fancyhdr} \pagestyle{fancy} \lhead{\footnotesize \parbox{11cm}{Custom left-head-note} } \lfoot{\footnotesize \parbox{11cm}{\textit{#2}}} \rfoot{\footnotesize Page \thepage\ of \pageref{LastPage}} \renewcommand\headheight{24pt} \renewcommand\footrulewidth{0.4pt} However, with \documentclass{letter}, this doesn't work at all. Suggestions are duly appreciated. EDIT: Here is sample code that doesn't work (for any apparent reason): \documentclass[12pt]{letter} \usepackage{fontspec}% font selecting commands \usepackage{xunicode}% unicode character macros \usepackage{xltxtra} % some fixes/extras % page counting, header/footer \usepackage{fancyhdr} \usepackage{lastpage} \pagestyle{fancy} \lhead{\footnotesize \parbox{11cm}{Draft 1} } \lfoot{\footnotesize \parbox{11cm}{\textit{2}}} \cfoot{} \rhead{\footnotesize 3} \rfoot{\footnotesize Page \thepage\ of \pageref{LastPage}} \renewcommand{\headheight}{24pt} \renewcommand{\footrulewidth}{0.4pt} \begin{document} \name{ Joe Laroo } \signature{ Joe Laroo } \begin{letter}{ To-Address } \renewcommand{\today}{ February 16, 2009 } \opening{ Opening } Content of the letter. \closing{ Yours truly, } \end{letter} \end{document}

• synchronized block in JSP tag class

  - by Sudhakar

  Hi, I am trying to find answer for the following ,for the past couple of days ,but couldnt find comprehensive answer Problem Statement I have a custom JSP tag class which handles a web form submission ,captures data and write it to same file in the filesystem. As all web applications,this can be triggeredsimultaneosly ,and i fear that multiple threads would be in action handling each of the submission (we all know thats how Servlet works.) CODE synchronized (this){ final String reportFileName = "testReport.csv"; File reportDir = new File( rootCsDirectory, "reports" ); if(!reportDir.isDirectory())reportDir.mkdir(); File reportFile = new File (reportDir, reportFileName); logReport(reportFile,reportContent.toString()); } ISSUE: - A File object can be opened by one thread for writing and at same time another thread might try to access and fail and throw an exception So i thought of synchronizing (on the object ) should solve the issue , but read some where that jsp engine would have pool of jsp tag objects, so i am afraid that synchronized (this) wont work and it should be changed to synchronized (this.getClass())

• What happens to an ActiveX control (COleControl) after the call to OnDestroy() ?

  - by richj

  I have an ActiveX control written in C++ that runs in Internet Explorer 8. Most of the time (approx 90%) when the tab or browser containing the control is closed, there is an access violation like this: The thread 'Win32 Thread' (0x1bf0) has exited with code 0 (0x0). Unhandled exception at 0x77b3b9fd in iexplore.exe: 0xC0000005: Access violation reading location 0x65007408. The access violation occurs after the call to OnDestroy() but before the call to the control's destructor. The debug output says: No symbols are loaded for any call stack frame. The source code cannot be displayed. None of my code is present in the stacktrace, although perhaps the heap was corrupted at some earlier point during execution. What lifecycle events does an ActiveX control receive between the call to OnDestroy() and the control's destructor?

• Define Instance Variable Outside of Method Defenition (ruby)

  - by Ell

  Hi all, I am developing (well, trying to at least) a Game framework for the Ruby Gosu library. I have made a basic event system wherebye each Blocks::Event has a list of handlers and when the event is fired the methods are called. At the moment the way to implement an event is as follows: class TestClass attr_accessor :on_close def initialize @on_close = Blocks::Event.new end def close @on_close.fire(self, Blocks::OnCloseArgs.new) end end But this method of implementing events seems rather long, my question is, how can I make a way so that when one wants an event in a class, they can just do this class TestClass event :on_close def close @on_close.fire(self, Blocks::OnCloseArgs.new) end end Thanks in advance, ell.

• Generating Component SEF URLs in Joomla

  - by Jarrod

  I have a custom Joomla component and a router for building my SEF URL's for use within the site, and everything is usually shiny - internally, all of my links look and act fantastic. I recently route a controller action that sends a list of links through email, and I've noticed that my URLs are coming out.... funky - hopefully someone can tell me why. Usually, my router generates an internal link that looks like this: http://localhost/Registry/calendar/265889635/Some-Long-Boring-Event However, when I send an email and preparing the same URL through the same router I get: http://localhost/Registry/Registry/component/calendar/569555803/Some-Long-Boring-Event Has anybody run into this issue before?

• Owner Vs PArent and Taction shortcuts on Frames

  - by Fred

  I have a form with a panel. I create frames at runtime and display them on the panel by setting frame's parent property to the panel. When creating panels I do not set the owner property because i manage myself the lifetime of the frame. Until now i got no problem. Next I put an TActionList on the frame with some shortcuts on the actions. I found that my actions did not execute until I set the owner property of the frame to the panel. Can someone can explain me that ? I thought that owner property was just about wich component is responsible to free the children components, and not responsible to forward key events.

• Creating multiple markers in Google Maps using XML

  - by Jessica Stanley

  I'm almost sure this question has been asked before, but for the love of me I just can't find the answer anywhere. Basically what I want to do is create multiple markers on a custom Google Map I'm building. I already have an XML file with the coordinates (lat/lng) and title of each item. I'd like to take the data from the XML file and use it to create markers on the map. I've found how to do this using KML files and MySQL/PHP, but I need to know how to do it in Javascript. One more thing: I have a .xml file of my own, so it won't be like I'll be getting the data from a webpage because I believe (from research I've done today) that the code for that may be different. If anyone knows if this has been posted somewhere else before, could you please direct me there? I've literally been searching all day, this is my last resort. Thanks a ton!!!

• I want to use 960 or Blueprint, but I also want to use lots of Padding and Borders, is it a good fit

  - by viatropos

  I started using 960 today and thought it would be really easy. However, trying to translate a site to 960 quickly proved tough for many reasons. The first is that I can't use any padding or borders. Unless of course I add many more divs. Same thing with borders. Question is, if I want to use lots of padding and borders (where padding and borders are either 5px "thin" or 10px "thick" styles), are 960 and blueprint overkill? It seems pretty easy to create a custom grid, but once I add padding and borders, 99% of the work is making sure the grid doesn't break. I still am going to end up lining everything up to a 960 grid with 12 columns, but I want to have padding and borders included in the width, and it seems that's not easily possible with 960 or blueprint. What are your thoughts?

• Magento: How do I retrieve values from fields submitted with the payment method?

  - by Joseph

  Ok. This is getting a little frustrating. I am trying to create a custom payment module for Magento. The purpose is to use Authorize.net's CIM so that we don't have to worry so much about PCI compliance. The issue I am having is that the users need to be able to access their previous credit cards and use those for purchasing. I have the previous cards being stored in the database. They are also being displayed in the form in the checkout process. My issue comes when I click continue after selecting the payment method. How do I get the values I submitted in the form? Specifically, the value of the radio button the saved code is attached to? I am not sure what if any code is needed for me to post, so let me know if you need anything in particular. Thanks.
