• 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

• Best Practice - Validating Input In Simple GUI Application?

  - by Alex

  I'm writing a GUI app with wxwidgets in C++ for one of my programming classes. We have to validate input and throw custom exceptions if it doesn't meet certain conditions. My question is, what is best practice when it comes to this? Should I write a seperate function that checks for errors, and have my event handler's call that function? Or should I do my error-checking in my event handlers? Or does it really matter? Thanks!

• How do I stall until a SharePoint List Item is Deleted with SPLongOperation?

  - by ccomet

  I have a workflow, which creates a task and deletes it after the task is edited and its useful information acquired. I created a custom edit form for the task, so I have an SPLongOperation that I can use to stall the page. This is necessary, because if I don't stall the page in some fashion, the person will see the task in the task list for the minute moment before the workflow gets to delete the task, and that is bad. So some code to stall the page until the task is fully deleted is necessary. I have currently implemented a solution for this, but I am unsatisfied with the approach. It basically is summed up to a while loop that calls SPList.GetItemById until it throws an error. Delibrately attempting to cause an error doesn't sit well with me, but I cannot think of a faster method for checking this. I'm looking for alternatives that would preferably work faster if not as fast, and preferably without relying on catching exceptions. Thank you in advance!

• 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.

• 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)

• What industries develop the highest quality software? Lowest quality? Why?

  - by Derek Mahar

  From your experience, of those industries that develop custom software for internal use such as financial services companies, which ones produce higher quality software measured in defect rates and, more qualitatively, ease of maintenance over the long term? What contributes the most to this achievement of higher quality? Is it due to better software development practices such as greater emphasis on testing or specification? Developers who better understand the tools or who are strong problem solvers? Better communication between team members? On the flip-side, which industries do you think produce the lowest quality software? Why?

• 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?

• Simulate Incorrect Content-Length Headers for HTTP in C#

  - by cfeduke

  We are building a comprehensive integration test framework in C# for our application which exists on top of HTTP using IIS7 to host our applications. As part of our integration tests we want to test incoming requests which will result in EndOfStreamExceptions ("Unable to read beyond end of stream") that occur when a client sends up a HTTP header indicating a larger body size than it actually transmits as part of the body. We want to test our error recovery code for this condition so we need to simulate these sorts of requests. I am looking for a .NET Fx-based socket library or custom HttpWebRequest replacement that specifically allows developers to simulate such conditions to add to our integration test suite. Does anyone know of any such libraries? A scriptable solution would work as well.

• 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())

• 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.

• 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.

• Add/remove UILocalNotification based on changes in my settings bundle

  - by Daniel Chui

  I have an app that sends a notification at the same time everyday, reminding the user to enter data into it. However, I want to give the user teh option to disable this as this could get very annoying, so I have an "Enable alerts" in a custom settings bundle. My question is, when the user toggles the switch in the settings bundle, can I add/remove the notifications that are already scheduled without having to enter the app again? note: I'm building and supporting for iOS 4.2.1, and I don't konw why but under "notifications" in the settings app, my app does not appear. I see it on ios 5.x devices though

• 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?

• My helper methods in controller

• 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?

• Strategies for Error Handling in .NET Web Services

  - by Jarrod

  I have a fairly substantial library of web services built in .NET that I use as a data model for our company web sites. In most .NET applications I use the Global ASAX file for profiling, logging, and creating bug reports for all exceptions thrown by the application. Global ASAX isn't available for web services so I'm curious as to what other strategies people have come up with to work around this limitation. Currently I just do something along these lines: <WebMethod()> _ Public Function MyServiceMethod(ByVal code As Integer) As String Try Return processCode(code) Catch ex As Exception CustomExHandler(ex) 'call a custom function every time to log exceptions Return errorObject End Try End Function Anybody have a better way of doing things besides calling a function inside the Catch?

• 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.

• 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}

• 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?

• .NET Setup Package Installer

  - by Duncan

  Hi, I have a .NET 3.5 Setup Package Project which installs my application successfully. The setup package deploys a number (around 70) custom files for use from within the application. From time to time I have the requirement of deleting some of these files, however upon restarting the executable, it automatically runs a portion of the Setup MSI again, and re-installs these files. The only way I can achieve my desired result at the moment is to delete the files after starting the executable. I have looked through the attributes on the files in the setup package such as Vital and PackageAs, however cannot seem to identify the required setting to achieve this. Does anybody have any idea what is needed to acheive this ? Much thanks

• 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?

• JSF : Better way to check for existence of <h:message for="id"/>

  - by user552809

  I have a form in which validation error message needs to be displayed below the input elements. The error needs to be highlighted by showing an error bubble around the error message and the input text. To achieve this, I need to check for the existence of h:messages for individual elements. I am able to check for the existence of global error messages as follows <h:panelGroup rendered="#{not empty facesContext.messages}"> </h:panelGroup> How I can check the same for specific client id (say first name). So something like faceContent.messages("creditCardNo") A solution I have currently is to create a custom resolver but was wondering if there is a better solution.

• Storing UTF-8 XML using Word's CustomXMLPart or any other supported way

  - by wpfwannabe

  I am writing a Word add-in which is supposed to store some own XML data per document using Word object model and its CustomXMLPart. The problem I am now facing is the lack of IStream-like functionality for reading/writing XML to/from a CustomXMLPart. It only provides BSTR interface and I am puzzled how to handle UTF-8 XMLs with BSTRs. To my understanding an UTF-8 XML file should really never have to undergo this sort of Unicode conversion. I am not sure what to expect as a result here. Is there another way of using Word automation interfaces to store arbitrary custom information inside a DOCX file?
