• is XULRUNNER suitable as a replacement for other C++ desktop applications frameworks such as QT?

  - by Gabriel Cuvillier

  XulRunner/Gecko seems to be really interesting for developing gui-intensive applications (by using widely used technologies such as HTML / CSS / SVG / XUL / Javascript). But the underlaying C++ APIS (XPCOM, NECKO, ...) looks so old and complex. Moreover the general lack of documentation/developper tools is really frightening. On the other hand, QT have a quite nice platform, and is well documented and supported. The UI part is really "traditional" though. What are your experiences with XULRUNNER, specially compared to other C++ desktop applications frameworks such as QT/GTK/MFC...? What is missing? What is awesome? Side question: If I wanted to migrate an existing MFC app to a cross platform C++ desktop application framework, would it be wise to use XULRUNNER instead of QT or GTK?

• CURL alternative - Design ideas

  - by Vincent

  All, I am looking for some web application design ideas here. I have a server X that hosts an SDK, which has the capacity to talk a piece of hardware. When I make an HTTPS request from an external PHP web application (hosted on Server Y) to Server X through curl, Server X gives JSON data as a response. I use this data to render my UI for the web app on Server Y. The above method seems to be slow and has a tendency to fail in production if there are too many concurrent requests. Can anybody let me know if there is an alternative to CURL or any other design people are using to pull data like this from servers? Thanks

• Differences in MS Office Charts

  - by simendsjo

  I'm about to do some Office integration creating charts from some data-sources and adding them to PPT slides. But some coworkers are saying using PPT charts is suboptimal as they are missing features of Excel charts, and are different in many ways. They're unable to come up with examples, and so am I... I found the following blog about Office2007, saying there are some differences in the programming model, but that they all use the same underlying engine. Are there really any differences in the capabilities of the charts? Is it mostly UI issues? What features are different/missing from PPT charts? Are these issues resolved in Office2010?

• jQuery slider not working in Wordpress plugin

  - by Matt Facer

  I've written a plugin for wordpress and I want to use a slider on my page. In it's most basic form (now) to test, I have the for the slider on my page <div id="wpge-slider"></div> then in the plugin, I have my init action add_action('init', 'wpge_init' ); function wpge_init() { wp_enqueue_script('jquery'); wp_enqueue_script('jquery-ui-core'); wp_enqueue_script('wpge_search_results', get_bloginfo('wpurl') . '/wp-content/plugins/myplugintest/js/wpge_search_results.js', array('jquery'), '1.0'); } then in my own javascript page, I have jQuery(document).ready(function($) { $("#wpge-slider").slider(); }); Everything (to me) looks ok, and the scripts ARE being called in the header. I can see them on the page... yet the slider is not showing. Can anyone see where I'm going wrong?!

• Your Django Development process/steps (Step by Step)

  - by AJ

  I want to know step by step process of how folks develop on Django here. I have seen that whenever I try to create a website in Django, I always get confused amongst: DB Schema/models.py UI/Template Structure Login module urls.py views.py How do you approach this? I may have missed something. You do not need to elaborate everything, just stepwise what you do. If you do two things at the same time (or side-by-side), that would also be helpful to mention. Thanks a lot.

• How to write "good" user interface text?

  - by Roddy

  Many applications are let down by the quality of the 'writing' in their user interfaces: typically, poor spelling, grammar, inconsistent tone, and worse yet, "humour" are the usual offenders. Are there good resources that can help developers to write UI messages that give a professional and positive impression to your customers, even when your code's going to hell in a handcart? Thanks, all — Some great resources here, so I will CW this question. I'm accepting Adam Sill's answer because it's the one that (as a developer of desktop apps) I found most pertinent.

• Standard documentation of Visual Studio commands?

  - by Borek

  Visual Studio has a concept of commands, i.e. actions executable by pressing a shortcut, entering them on the Command Window etc. Visual Studio itself documents its commands (at least some of them) but I was wondering if there is a unified way to get information about any command, e.g. coming from ReSharper, TestDriven.NET etc. What I'd like to see for every command: Textual description of the command List of parameters and their types/allowed values I've never developed a VS addon / extension so am not sure if this question even makes sense but from the user perspective, some documentation would be greatly appreciated. BTW, is the Command Window the best place to get at least an overview of all the commands available? ToolsOptionsKeyboard is another place where I can see shortcuts also but the UI is not very convenient...

• Better Alternative to Telerik Draggable Panel ?

  - by user284523

  When putting a video in a Telerik Draggable Panel, when dragging the panel, on Firefox the video restart all over again because DOM is reconstructed. They don't seem to have an answer to this. Also we can't seem to be able to control the z-index as it doesn't take into account: when moving the panel over other telerik controls, the video slips under. So any other draggable panel that wouldn't have these annoyances ? Telerik doesn't seem to give any answer so we're afraid we're stuck and we cannot afford to wait longer. Currently think about using Yahoo UI.

• Frame skipping with OpenGL and WinAPI?

  - by user146780

  Here is my situation. I'm creating a drawing application using OpenGL and WinAPI. My OpenGL frame has scrollbars which renders the screen and modifies GlTranslatef when it gets a scroll message. The problem is wen I get too many shapes the scrollbar is less responsive since it cannot rerender it each and every time it gets a scroll message. How could I make it so the scrollbar has priority. I want it to skip drawing if it would compromise the smoothness of the scrolling. I thought of doing rendering on a separate thread but I was told all UI things should stay on the same thread. Thanks

• Problem getting value from "Checkbox group value prompt"

  - by Veer

  Hi, I've value prompt with ui:checkbox group parameter: p_IsLastMonth Name: Prompt_IsLastMonth ItemCount: 1; UseValue:Yes, DisplayValue: LastMonth? and two Date Prompts. Whenever the checkbox is checked, the UseValue 'Yes' is passed to the parameter 'p_IsLastMonth'. But whenever the checkbox is left as it is, it results in an error. Element 'selectOptions' is not valid for content model: 'All(style,defaultSelections,conditionalStyles,conditionalRender,XMLAttributes)' I also tried giving a default value. But the default value has to be in the collection. But i want only one checkbox to be displayed. I tried with html checkbox. But i'm not able to send the value 'either yes or no' to the parameter through javascript because however the finish button overrides the value. Any help?

• Why should I use MVVM when it breaks built in functionality

  - by Jakob

  I'm struggling to grasp why MVVM is really a good pattern to implement in riaserivces, To me there's nothing but trouble to it, it just add's another tier that I have to code. I Get that I could change the UI, but really I don't need to. Instead i won't be able to user out of the box functionality with riaservices, datagrid, dataform all controls require some implementation. Why can't it just be simple? Is there really no way to get MVVM to automatically set "IsBusy" and all the dataform edit functionality. It's like reinventing the wheel to me, and it seems that I'd be able to write code much faster just using riaservices

• [Java] Cut <br/>-Tags from String end

  - by Robert M.

  Hello everybody, I am currently developing a Web-Application using Java EE where I'm using a Rich-Javascript-Editor (http://www.primefaces.org/showcase/ui/editor.jsf). As the user can easily add too many linebreaks that will be convertet to linebreak-tags, I need to remove all these Tags from the end of a String. Is there an elegant way of using Regex to accomplish this? An example String would be: "This is a test <b>bold</b><br/><br/>" Where obviously the last two tags have to be removed. Thank you in advance for any help Best Regards, Robert

• Looking for Google Reader javscript commands for controlling events

  - by JayCrossler

  I've played in the /reader/ui/ code for a few hours now, and couldn't figure this out. Also, I didn't see any exact help when searching StackOverflow. This is really a JavaScript un-obfuscator question. I'm looking for a way to call the obfuscated Google Reader javascript commands... and am having trouble determining what actual function is called when the "Next Items" button is pressed or the spacebar is hit. I've tried using Firebug as well as FireEvents to track it down, but it's just too well hidden. Any ideas? Something that I could type into the URL bar and make it run, something like 'javascript:SH("entries-down", "click");void(0);' Thanks in advance! And, please let me know if it's against Google's terms of service to de-obfuscate their code to view these JavaScript commands.

• Eclipse Plugin: Enablement of an Action based on the current selection

  - by Itay

  I am using the org.eclipse.ui.popupMenus extension point for adding a sub-menu whose Action that is bounded to the following class: public class MyAction implements IObjectActionDelegate { private Logic logic = Logic.getInstance(); // Singleton public void setActivePart(IAction a, IWorkbenchPart targetPart) { // Nothing here } public void run(IAction a) { // Do something... } public void selectionChanged(IAction a, ISelection s) { a.setEnabled(logic.isEnabled(s)); } } This action is working correctly in most cases (including the call a.setEnabled() in selectionChanged()). My problem at the very first time my action is being invoked. The selectionChanged method is called only after the menu item has been displayed (and not when the user has made the selection) which means that the call to a.setEnabled() will have no affect. Any ideas on how to make my action receive selectionChanged() notifications even before the fist time it is being invoked?

• What really is the purpose of "base" keyword in c#?

  - by Pandiya Chendur

  Thus for used base class for some commom reusable methods in every page of my application... public class BaseClass:System.Web.UI.Page { public string GetRandomPasswordUsingGUID(int length) { string guidResult = System.Guid.NewGuid().ToString(); guidResult = guidResult.Replace("-", string.Empty); return guidResult.Substring(0, length); } } So if i want to use this method i would just do, public partial class forms_age_group : BaseClass { protected void Page_Load(object sender, EventArgs e) { //i would just call it like this string pass = GetRandomPasswordUsingGUID(10); } } It does what i want but there is a "Base" keyword that deals with base class in c# ... I really want to know when should use base keyword in my derived class.... Any good example...

• Poll database using jQuery/Ajax

  - by Gav

  Hi guys, I am trying to use jQuery (latest version) & ajax to poll a mysql db every x seconds, post.php does a simple search query on the table and limits to 1 row. (eg SELECT id FROM TABLE LIMIT 1) I've got some other jQuery UI (using v1.8) code that displays some modal/dialog boxes on the screen, simply put if post.php returns something from the db I need to initialise the dialog to pop up onto the screen. I've done all the popup stuff I am just having issues joining all these bits together - i've added some pseudo code of how i expect this to work. Thanks in advance var refreshId = setInterval(function(){ $.ajax({ type: "POST", url: "post.php", data: "", success: function(html){ $("#responsecontainer").html(html); } }); }, 2000 );s /* proposed pseudocode */ if (ajax is successful & returns a db row to #responsecontainer) { show jQueryUI modal (done this bit already fortunately) }

• Building a dll with .lib files

  - by Manish Shukla

  I have a C++ project which is build via bjam. With 'install' rule in Jamroot i am able to create statically linked libraries (.lib files) for my project. My question is, how i can build a load-time DLL (or run-time DLL is also fine) with these .lib files? More Info: I am building my project with bjam in windows using msvc. When i tried compiling my project under visual C++ 2008, it complied and linked just fine but when i used bjam with msvc for compilation, it started giving linking errors and showing dependency from other project folders. Why was this behavior via bjam but not shown in vc++ UI.

• Relogging a user in with different Spring Security Authorities programmatically

  - by user1331982

  PreReq: User logs in and is given roles got from the database using a custom implementation of userService. i.e. authentication-provider user-service-ref="securityPolicyService" The implemented method loadUserByUsername gets called and the roles are load for the user for the particular club they are logging into, Default one is loaded first time in. The user then click on a different club from the UI and I call a method on a service that gets the new list of authorities for this club. I then perform the following: Object principle = SecurityContextHolder.getContext().getAuthentication().getPrincipal(); SecureMember sm = (SecureMember) principle; Authentication auth = new UsernamePasswordAuthenticationToken(sm, null, newAuthories); <br><br> SecurityContextHolder.getContext().setAuthentication(auth);<br> request.getSession(false).invalidate(); SecureMember extends User from SpringFramework. The problem is the SecureMember authorities are never updated with the new ones. thanks Gary
