• Should I use multiple ListViews?

  - by janfsd

  Hi to everybody! I have a RelativeLayout with different elements. I was planning to have two ListViews on it, but I have noticed there are some problems with scrolling. Since each ListView only shows a maximum of 5 rows should I try to make some kind of custom adapter to merge those ListViews? Or is it better to replace the ListView with a LinearLayout/RelativeLayout and add the rows as I get them manually? (like the first answer in here: http://stackoverflow.com/questions/1778485/android-listview-display-all-available-items-without-scroll-with-static-header ). Which should be the proper way on doing this? or is there another way? Also, each row will have an OnClickListener.

• VS 2010 breaks my keydown events

  - by Erik Karlsson

  I have a custom control, a groupbox, which reacts on key events on a assigned key. It is possible to remove this groupbox, as well as adding more dynamically. Havnt been any trouble in VS 2008 so far. Two days ago i installed VS 2010. And i started to get multiple event fireing, and removing a groupbox did not remove the specific key events attached to it. Where did it go wrong? I use -= on the events present in the gruopbox code to remove them before removing the groupbox.

• 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.

• 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)

• 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?

• 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?

• 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.

• 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.

• maya "export all" window blocks my plugins script UI

  - by Hinchy

  I'm writing a custom File Translator for Maya which can export only (I have only declared the writer function). Currently having a problem with the MEL script which defines the plugin's options as a GUI. Currently I have a blank Maya scene, go to "file-export all". This creates the "File Export All" dialog, I then select my plugin exporter which runs my MEL script to create the bespoke options window. This new window is created behind the "File Export All" dialog and is not selectable! Do I have to place my export plugin specific options within the export all dialog rather than placing them in a separate window? Thanks for any links, tips or pointers you can provide.

• Removing views from UIScrollView

  - by mohan

  I have two UIScrollViews that I move images between. The user can drag and forth between the scroll views. I am trying to animate the movement of the image from one scroll view to another. In -touchesMoved (handled in my UIViewController which has two custom UIScrollViews that intercept touch and sends to my UIViewController), I am trying to set the "center" of my UIImageView that is being moved. As it is moved, the image gets hidden behind the UIScrollView and not visible. How do I make it appear on top of the UIScrollView? I am able to handle the -touchesEnded properly by animating in the destination scroll view. I am also confused about -convertPoint:fromView: usage in the iPhone Programming Guide (See Chapter 3, Event Handling). If the touch coordinates are in window coordinates, to change my view (UIImageView inside a UIScrollView which is inside a UIView and inside a window) center don't I have to use -convertPoint:toView:, i.e., imageView.center = [self.view.window convertPoint:currentTouchPosition toView:imageView]; What am I missing?

• Different return XML in a WCF Operation

  - by Sean Hederman

  I am writing a service to a international HTTP standard, and there is one method that can return three different XML results, call them Single, Multiple and Error. Now I've written an IXmlSerializable class that can consume each of these results and generate them. However, WCF seems to insist that I can only have a single return XML root name. I have to choose an XmlRoot for my custom object of either Single, Multiple or Error. How can I set up WCF so that I can choose at runtime what the root will be? This is what I have currently. /// <summary> /// A collection of items. /// </summary> [XmlRoot("Multiple", Namespace = "DAV:")] public sealed class ItemCollection : IEnumerable<Item>, IXmlSerializable /// <summary> /// Processes and returns the items. /// </summary> [WebInvoke(Method = "POST", UriTemplate = "{*path}", BodyStyle = WebMessageBodyStyle.Bare)] [OperationContract] [XmlSerializerFormat] ItemCollection Process(string path);

• How to preprocess a Django model field value before return?

  - by Satoru.Logic

  Hi, all. I have a Note model class like this: class Note(models.Model): author = models.ForeignKey(User, related_name='notes') content = NoteContentField(max_length=256) NoteContentField is a custom sub-class of CharField that override the to_python method in purpose of doing some twitter-text-conversion processing. class NoteContentField(models.CharField): __metaclass__ = models.SubfieldBase def to_python(self, value): value = super(NoteContentField, self).to_python(value) from ..utils import linkify return mark_safe(linkify(value)) However, this doesn't work. When I save a Note object like this: note = Note(author=request.use, content=form.cleaned_data['content']) The conversed value is saved into the database, which is not what I wanna see. Would you please tell me what's wrong with this? Thanks in advance.

• Changing UINavigationBar font in Swift

  - by dcgoss

  I have a UINavigationBar with a title in the middle. I have added a custom font ("Comic_Andy.ttf") to my app (I have checked info.plist to make sure it's listed, and I have checked the Copy Bundle Resources to make sure it has been added), and I would like the title of the UINavigationBar to be displayed in that font. From what I can gather it seems as though I'm supposed to use this in my ViewController: myNavigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "Comic_Andy", size: 22)] I placed that method in the viewDidLoad function of the ViewController. I have also tried this in the didFinishLaunchingWithOptions function of the AppDelegate: UINavigationBar.appearance().titleTextAttributes = [NSFontAttributeName: UIFont(name: "Comic_Andy", size: 22)] I am programming in Swift, in XCode 6 Beta 6. Many resources regarding this task have mentioned using a method called setTitleTextAttributes, which is nowhere to be seen. I can't figure it out for the life of me - I've probably spent close to 3 hours on it by now - I have checked every StackOverflow answer, every website, so please do not mark this as a duplicate. Many thanks in advance!

• Container of shared_ptr's but iterate with raw pointers

  - by Sean Lynch

  I have a class that holds a list containing boost::shared_ptrs to objects of another class. The class member functions that give access to the elemets in the list return raw pointers. For consistency I'd also like to be able to iterate with raw pointers instead of shared_ptrs. So when I dereference the list iterator, I'd like to get raw pointer, not a shared_ptr. I assume I need to write a custom iterator for this. Is this correct? If so can someone point me in the right direction - I've never done this before.

• 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

• 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())

• 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.

• Testing ASP.NET security in Firefox

  - by blahblah

  I'm not sure whether this question belongs on StackOverflow or SuperUser, but here goes nothing... I'm trying to test out some basic security problems on my personal ASP.NET website to see exactly how the custom validators, etc. work when tampering with the data. I've been looking at the Firefox extension TamperData which seems to do the trick, but it doesn't feel very professional at all. The issues I'm having with TamperData is that the textbox for the POST data is way too small to hold the ASP.NET view-state, so I have to copy that data into Emacs and then back again to be productive at all. I also don't like that there doesn't seem to be an option to only tamper with data which is from/to localhost. Any ideas on better extensions for the task or better methods to test it?

• 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.

• Getting 'AJAX Control Toolkit is undefined' when setting the CombineScripts="true"

• Why is this leaking memory? UIImage `cellForRowAtIndexPath:`

  - by Emil

  Hey. Instruments' Leaks tells me that this UIImage is leaking: UIImage *image = [[UIImage alloc] initWithContentsOfFile:[imagesPath stringByAppendingPathComponent:[NSString stringWithFormat:@"/%@.png", [postsArrayID objectAtIndex:indexPath.row]]]]; // If image contains anything, set cellImage to image. If image is empty, try one more time or use noImage.png, set in IB if (image != nil){ // If image != nil, set cellImage to that image cell.cellImage.image = image; } image = nil; [image release]; (class cell (custom table view cell) also releases cellImage in dealloc method). I haven't got a clue of why it's leaking, but it certainly is. The images gets loaded multiple times in a cellForRowAtIndexPath:-method. The first three cells' image does not leak (130px high, all the space avaliable). Leaks gives me no other info than that a UIImage allocated here in the code leaks. Can you help me figure it out? 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}

• jQuery AJAX converting variable string to html styled text

  - by sadmicrowave

  I've got an AJAX transmission of a variable string in my primary coding language (Visual FoxPro 9) that looks like this: AjaxResponse = CREATEOBJECT("Custom") lcMessage = "<li class='hello'>Hello</li>" AjaxResponse.AddProperty("Reply", lcMessage) Response.ContentType = "text/html" Response.Write(AjaxResponse.Reply) While using the jQuery function .ajax() I've created a success: function that looks like this: $.ajax({ url: 'index?Proc=GetUuserHistory', dataType: "html", success: function(data){ $("div#history-text").text(data); }; }); My problem is that the text inserting into 'div#history-text' is unformatted and contains the li tags still. I've tried substituting the .text for .prepend, .append, and .html with no luck...is there a way to convert this string back to html format after its been received using Ajax?

• 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?
