• How can I implement a "wizard" style page using JQuery?

  - by Mark Brittingham

  I am implementing a questionnaire on the web and I'd like for each block of questions to have its own "page" so the user doesn't have to scroll. However, page loads have two problems: a) they take time (and have a noticeable flicker/refresh) and b) such an approach would force me to do a data table insert plus multiple updates (or store it all in my session). How can I use JQuery to let the user page through the questionnaire on the client side, answering questions as he goes? I'll then be able to handle the data store when all the answers are submitted at the end. One other thing...is there a way to make sure that the session doesn't time out if the user takes awhile?

• Online Image Slideshow Question. File Access Problems.

  - by msandbot

  Hi, I have a flash .swf file that I embed on my webpage. On my server I have the .swf file and multiple image folders. I would like to load every file in one of those folders into the flash slideshow. How should I go about doing this? I tried used Air but it doesn't work on my system as an application so I doubt it will work online. Eventually I plan on making a menu where you can select different folders to display and since they are of different sizes, a foreach loop would be optimal. Keeping a txt file with the number of images is also possible if theres a way to read that in, but I would prefer the more dynamic approach. I am working towards using php for the website if that helps find a solution. Thanks, -Mike Also my slideshow works great online currently but i have to hardcode in the number of files.

• Data bind enum properties to grid and display description

  - by TrueWill

  This is a similar question to How to bind a custom Enum description to a DataGrid, but in my case I have multiple properties. public enum ExpectationResult { [Description("-")] NoExpectation, [Description("Passed")] Pass, [Description("FAILED")] Fail } public class TestResult { public string TestDescription { get; set; } public ExpectationResult RequiredExpectationResult { get; set; } public ExpectationResult NonRequiredExpectationResult { get; set; } } I'm binding a BindingList<TestResult> to a WinForms DataGridView (actually a DevExpress.XtraGrid.GridControl, but a generic solution would be more widely applicable). I want the descriptions to appear rather than the enum names. How can I accomplish this? (There are no constraints on the class/enum/attributes; I can change them at will.)

• Can't change header logo in Magento?

  - by Jared

  Hello, I have created my own theme for magento, and I am trying to edit the logo and am having difficulty. I have created my own local/Mage/Page/etc/config.xml file, and specified within the config the following: <logo_src>images/Race-Ramps-logo-streaked-gradient.gif</logo_src> I created a custom layout in the file as well. I can see the custom layout file in the CMS, but my changes to the logo do absolutely nothing. I have even tried changing the original core config.xml, it still stays the same. On multiple websites, I have been told to go to System Configuration Design Header, but I do not have the header option? Help please!

• How to open different App version for one given file extension

  - by Erik Lenaerts

  We have a data files with an extension ".ppx" for our business app here. Users will typically have multiple versions of the application installed (side by side) for example version 1 and version 2. The ppx files are xml files and they contain the version of the app they were created from (v1 or v2). Lets say that we have AFileCreatedWithAppv1.ppx and AFileCreatedWithAppv2.ppx opens with version 1 or version 2 of our app respectivly when they both have the same file extension? It must be doable since that is what Visual Studio does. In fact, they even provide different icons for the same .sln extension to indicate what Visual Studio version it will open with. I learned that Visual Studio is using the Selector or Launcher in between, but then again, how do they change the icons in Windows? cheers :)

• Recursive query question - break rows into columns?

  - by Stew

  I have a table "Families", like so FamilyID PersonID Relationship ----------------------------------------------- F001 P001 Son F001 P002 Daughter F001 P003 Father F001 P004 Mother F002 P005 Daughter F002 P006 Mother F003 P007 Son F003 P008 Mother and I need output like FamilyID PersonID Father Mother ------------------------------------------------- F001 P001 P003 P004 F001 P002 P003 P004 F001 P003 F001 P004 F002 P005 P006 F002 P006 F003 P007 P008 F003 P008 In which the PersonID of the Father and Mother for a given PersonID are listed (if applicable) in separate columns. I know this must be a relatively trivial query to write (and therefore to find instructions for), but I can't seem to come up with the right search terms. Searching "SQL recursive queries" has gotten me closest, but I can't quite translate those methods to what I'm trying to do here. I'm trying to learn, so multiple methods are welcome, as is vocabulary I should read up on. Thanks!

• magic records being deleted

  - by chris

  i have customised oscommerce to pull in a csv file of products, delete anything thats not with an image/proper description/proper title gets removed. The import runs on a cron job basis pulling information from a supplier, it hasnt run since yesterday but a product has disappeared- Anyone who has used oscommerce will know that, product information is stored over multiple tables. example is- products product_description and so on. the thing that has got me that the information is deleted from the product table but not from the product_description table. The product that is being deleted is a manually input one which carries a special tag/prefix on the model item of the product table. Therefore shouldn't be touched at all. Am clueles as what is going on. Is there mysql integrity checks deleting records? could there be another plugin working on oscommerce?

• CSS [custom?] attributes

  - by Michael

  radio[pane] { list-style-image: url("jar:resource:///chrome/classic.jar! /skin/classic/browser/preferences/Options.png"); } radio[pane="prefpane-appearance"] { -moz-image-region: rect(0px, 32px, 32px, 0px); } radio[pane="prefpane-appearance"]:hover, radio[pane="prefpane-appearance"][selected="true"] { -moz-image-region: rect(32px, 32px, 64px, 0px); } Can anyone explain a syntax of this css, particularly what is pane.. I couldn't find such attribute for radio element in context of XUL. So I guess it's some custom attribute? If it is, then how it is evolving through the lines, first declaration, then several assignments? It has also selected, which means can have multiple custom attributes? How can those attributes be used later?

• Tab versus space indentation in C#

  - by Lars Fastrup

  I sometimes find myself discussing this issue with other C# developers and especially if we use different styles. I can see the advantage of tab indentation allowing different developers to browse the code with their favorite indent size. Nonetheless, I long ago went for two space indentation in my C# code and have stuck with it ever since. Mainly because I often disliked the way statements spanning multiple lines are sometimes messed up when viewing code from other developers using another tab size. Recently a developer at one of my clients approached me and asked why I did not use tabs because he preferred to view code with an indentation size of 4. So my question is: Which style do you prefer and why?

• SVN Authorization

  - by Weslei

  I am trying to setup SVN authorization (authentication works fine already) and my AuthzSVNAccessFile looks like the following: [groups] todos = user1, user2 proj = user1 [/] @todos = r [/myproj] @proj = rw However, I can checkout the content of proj (as user1) but I can't commit to it... If i change the file changing to the following: [groups] todos = user1, user2 proj = user1 [/] @todos = rw [/myproj] @proj = rw I can successful commit... Anyone knows what's wrong with my access file? I am using SVN with SVNParentPath, to point to a folder containing multiple repositories. The errors it gives are: svn: Error: Server sent unexpected return value (403 Forbidden) in response to CHE CKOUT Thanks.

• Need help using ThemeRoller

  - by Music Magi

  Hi - I'm using DataTables to dress up a table I'm using to display XML results based on an XSL transformation. I have everything working from a technical sense (paging, sorting, filtering), but I'm trying to figure out to use a ThemeRoller theme to make it look like they have on their website. So far, I have added the following file to my project with its reference: <link type="text/css" href="css/custom-theme/jquery-ui-1.8.7.custom.css" rel="stylesheet"/> and enabled ThemeRoller themes using the following as per the DataTables website: $(document).ready(function() { $('#mainTable').dataTable( { "bJQueryUI": true, "sPaginationType": "two_button" }); }); The table gets styled, but it doesn't look right with the header rows being too wide and things being on multiple lines that should be on one line. Any indication as to what I'm doing wrong? Thanks very much in advance.

• WPF: Turning off animations, data binding temporarly for invisible objects?;)

  - by TomTom

  I have a window that contains a tab control - basically multiple sheets with visualizations on them. The visualtizations are: possible very resource intensive during rendering relying on constant data updates to update their underlying models Obviously only one sheet can be visible every time ;) Anyone knows of a good way to turn off all visualization, animations, data binding for a control / panel and it's contained controls? If I would find a way to do that, I could simply turn off all the invisible sheets and reactivate them as needed. The models must be kept running - some of the visual stuff is pretty complex and really relies on constant data updates, and recalculating it when someone switches tabs would be too hard.

• Setting instance names on keyframes quickly in AS3

  - by Boon

  Right now in Flash CS3 and up (using Actionscript 3) if you have the same instance that is used in multiple keyframes in a layer, and you decide to assign or change the instance name later, you would have to go to each keyframe and set the instance name. This is a big nuisance. Is there a quicker or better way to do this? NOTE: In AS2, you can set the name by using name property of the MovieClip in your code in the onLoad handler of the MovieClip class so it's done once and for all. Unfortunately in AS3, you are not allowed to set the name property anymore.

• Doing a join across two databases with different collations on SQL Server and getting an error.

  - by Andrew G. Johnson

  I know, I know with what I wrote in the question I shouldn't be surprised. But my situation is slowly working on an inherited POS system and my predecessor apparently wasn't aware of JOINs so when I looked into one of the internal pages that loads for 60 seconds I see that it's a fairly quick, rewrite these 8 queries as one query with JOINs situation. Problem is that besides not knowing about JOINs he also seems to have had a fetish for multiple databases and surprise, surprise they use different collations. Fact of the matter is we use all "normal" latin characters that English speaking people would consider the entire alphabet and this whole thing will be out of use in a few months so a bandaid is all I need. Long story short is I need some kind of method to cast to a single collation so I can compare two fields from two databases. Exact error is: Cannot resolve the collation conflict between "SQL_Latin1_General_CP850_CI_AI" and "SQL_Latin1_General_CP1_CI_AS" in the equal to operation.

• Restart Delphi Application Programmatically

  - by Smasher

  It should not be possible to run multiple instances of my application. Therefore the project source contains: CreateMutex (nil, False, PChar (ID)); if (GetLastError = ERROR_ALREADY_EXISTS) then Halt; Now I want to restart my application programmatically. The usual way would be: AppName := PChar(Application.ExeName) ; ShellExecute(Handle,'open', AppName, nil, nil, SW_SHOWNORMAL) ; Application.Terminate; But this won't work in my case because of the mutex. Even if I release the mutex before starting the second instace it won't work because shutdown takes some time and two instance cannot run in parallel (because of common resources and other effects). Is there a way to restart an application with such characteristics? (If possible without an additional executable) Thanks in advance.

• Relative Paths, etc. on an Apache server

  - by Matt H.

  I'm really stuck here. I have 2 issues at once: First, my site is stored (both on local development and on live server), in a subdirectory.. as I'm working on multiple sites. i.e. /Sites/www.mysite.com/(site files here) When I'm referring to files in my web pages, I want to refer to, say, my /images directory without hard-coding every occurrence as /www.mysite.com/images/myfile.jpg Is there a way to simply redefine how the leading "/" gets interpreted by the server? Question two, concerning PHP mod_rewrite I have this set of rewrite rules. The objective is to turn www.mysite.com/faq into www.mysite.com/index.php?page="faq" RewriteEngine On RewriteCond %{REQUEST_URI} !mysite.com RewriteRule (.*) mysite.com/$1 RewriteRule ^([a-zA-Z0-9_-]+)$ /mysite.com/index.php?site=$1 RewriteRule ^([a-zA-Z0-9_-]+)/$ /mysite.com/index.php?site=$1 I don't have a problem when a url gets passed in the 2nd-to-last format (as the example above). However, if the trailing "/" is added: www.mysite.com/faq/, my external script references break: (such as src=js/script.js)...

• GUI system architecture?

  - by topright

  I'm designing GUI (graphical user interface) system for a game engine (C++). Idea is to create a heirarchy of GUI controllers like Focusable, Hoverable, Dragable etc. Every GUI component can attach multiple controllers, they modify component's behaviour. I think it gives flexible system and protects from code duplication. Different instances of the same GUI class can have different complex behaviours (may be, even change it dynamically), so this approach looks practical. The other choice is to add focused, hovered, dragged etc. flags in the base GUI component class. It looks like overhead and not that flexible. Another solution is to use Decorator pattern and wrap objects with FocusDecorator, HoverDecorator etc. Maintaining such system looks a bit harder. Question: What are pitfalls in my solution? May be you have seen a better approaches in GUI systems? What are the best ways of implementing such flexible complex system?

• How do you write a consistent UI Automation for MS? MSAA & UI Automation don't seem to overlap.

  - by Greg

  Working on a general Automation tool, considering moving from Win32 Message hooks to .net UI Automation, however the feature set of UI Automation doesn't cover all we have in Win32 and still doesn't seem to support all the GUI on Windows. One such example is Windows Live Messenger. Windows Live messenger 2009 is still using the older DirectUIHwnd to draw the gui. This means that you can't use windows messages to send to the controls, because the controls don't have their own HWND. It also seems to defeat the new .net UI Automation framework though the documentation seems to make out as if it can be joined in the UI Automation and Microsoft Active Accessibility document. Looking at MS Accessibility pointed to Active Accessibility 2.0 SDK Tools which showed that MSAA can interact with the contents. Is there some trick to getting the older MSAA technology that UI Automation seems to be trying to replace to actually work with UI Automation? I'd rather not have multiple solutions trying to automate the same windows for windows unlike Windows Live Messenger where each of these techniques is valid and will work.

• Macro to copy data from one sheet to another based on the current date

  - by SgtSnafu

  Does anyone have a macro that copy data from one sheet to another based on the current date? I am working with a single workbook of three sheets. Sheet one will hold the manual input of daily production figures for multiple plants, sheet two is to hold ongoing daily data, keyed on sheet one. The macro will be associated with a button, so that once clicked it would search for every row that has a date of today, and copy that row to the next available blank row on sheet two. Sample Data... Plant 1 Input Date - $ Produced - Labor Hour 3-29-10 - 4538 - 8 3-30-10 - 7862 - 12 3-31-10 4-1-10 4-2-10 Plant 2 Input Date - $ Produced - Labor Hour 3-29-10 - 4545 - 9 3-30-10 - 7645 - 12 3-31-10 4-1-10 4-2-10

  - by Oscar Cabrero

  hi i need to select only the first row from a query that joins tables A and B, on table B exist multiple records with same name. there are not identifiers in any of the two tables. i cannt change the scheme either because i do not own the DB TABLE A NAME TABLE B NAME DATA1 DATA2 Select Distinct A.NAME,B.DATA1,B.DATA2 From A Inner Join B on A.NAME = B.NAME this gives me NAME DATA1 DATA2 sameName 1 2 sameName 1 3 otherName 5 7 otherName 8 9 but i need to retrieve only one row per name NAME DATA1 DATA2 sameName 1 2 otherName 5 7 i was able to do this by adding the result into a temp table with a identity column and the select the Min Id per name. the problem here is that i require to do this in one single statement. this is a DB2 database thanks

• Difficulties of transforming a Java program to another language (or vice versa)

  - by NomeN

  Is there anything simple Java can't do that can be done in a similar language or vice versa? Lets say you have a piece of software in language X and you rewrite it entirely to Java (or the other way around), what are the little things that would seriously hamper the translation? At first I was thinking of comprehensions or multiple exit loops, but these are easily rewritten with a for_each loop with an if statement and a local variable respectively. Maybe Exceptions? But which language does not have a similar construct? Polymorphism? But I don't see how I could show that in a few lines. I'm looking for a short and sweet example, that would give some serious headache to work around.

• Django filter with two constraints on related model

  - by BJ Homer

  I have a django app with models as follows: A Question model An Answer model, with a ForeignKey back to the Question. (A question can have multiple answers.) A Flag model, with a ForeignKey to the Answer. (An answer can be flagged as inappropriate.) All of the above also have a user field, defining the user that created that object. I'm trying to get a list of all Questions with answers from the current user which have been flagged. I tried this: Question.objects.filter(answer__user=user).\ filter(answer__flag__isnull=True).distinct() … but I believe that will return a list of Questions with answers from the current user and with answers which have been flagged, but will not necessarily guarantee that it is the user's answer that has been flagged. Is there an easy way to do this? Basically, I want to make the answer part of the filter refer to the same answer on both of them. Please let me know if something is unclear.

• Workaround for richfaces combobox hotkey bug

  - by John

  Hi, Does anyone know a workaround for the bug https://jira.jboss.org/jira/browse/RF-8076 ? Just to clarify things, we have a form with multiple inputs, one of them being a combobox with auto complete features. We've setup a hotkey via <rich:hotKey key="return" ... /> It works great everywhere except in the combobox, and I would really like to get it working on the combobox as well. The behaviour I want when the ENTER key is pressed inside the combobox is: If the combobox context was modified by auto complete then do nothing Else action the event on ENTER key pressed We're running on seam/richfaces. I'm open to any workaround, but simplicity is much sought for. Thanks!

• Where to store selected language on multilingual site: session/cookies or url?

  - by tig

  I have a site that has all its content translated to multiple languages and has no accounts (to set prefered language there). I can detect preferred language using Accept-Language, ip or anything else. I have 3 ways to store user language selection: Detect language and store it in cookie/session and allow switching language (and also store it in cookie/session) Use detected language if there is no language specified in url, and show links to url with different language Use default site language and show links to other languages Storing langage in url can be of any type: different domain, subdomain, or somewhere in url I think about first case as it allows me to send one url to anyone and it will be presented to them in their preferred language. But another opinion is that different language means different data, so it must have different link.
