• Web Designer looking to learn back-end programming...

  - by Tabetha Moe

  Hello, my name is Tabetha and I have a question... I am a web designer, but I always find that while designing the layout and coding the design I come up with great ideas for websites. I would like to know where I need to start in order to learn back-end programming not only for the knowledge, but also for the challenge of it. I have searched online but can't seem to find the information I am looking for. If anyone can give me a simple, straight-forward "this is what language you need to learn" answer, or perhaps guide me in the right direction I would appreciate it ten-fold. I am a complete noob when it comes to this, so even the most basic information is probably a pearl of wisdom for me. :)

• PHP File Upload + jQuery

  - by st4ck0v3rfl0w

  Hello Everyone, So I have my upload script working just fine, but now it's a matter of making it look the way I want for my layout. <input type="file" name="userfile" id="userfile"/> This obviously shows a textbox with a Choose File button. What I really need is my own custom button (which will ultimately be an image) that upon successful file select (not upload quite yet) triggers a jQuery event to show a div. I do NOT want the filename textbox to show. Basic steps outlined below. User clicks on image button to upload their file User selects file jQuery shows a div with more fields User clicks submit and file is uploaded

• How can I get rails to not render escaped quotes as \&quot;

  - by James

  In my layout I have <% @current_user.popups.each do |p| %> <% content_for :script do %> <%= "$(document).ready ( function() { $.jGrowl(\"#{p.message}\", { sticky: true }) });" %> <% end %> <% end %> And then in the script section I have <%= yield :script %> The problem is that this renders the escaped quotes as \&quot; and javascript doesn't like this. How can I stop this from happening? Or is there another approach to this? I can't use single quotes because I'd like to have some html in the message. I'd appreciate any help.

• Android: How can we change the view in the tabs?

  - by achie

  I want to provide a clickthrough on the list in a tab which opens another view. I need to open the new view within the same tab. I then need to provide a back button on the changed layout to change the view to original view. I have tried this. Intent intentA = new Intent(this, AView.class); Now I am trying to access the tabSpec from main activity class[MainTabView] and set the intent as follows. MainTabView.tabSpec1.setContent(intentA); MainTabView.mTabHost.setCurrentTab(0); MainTabView.mTabHost.invalidate(); But this does not change the view immediately but changes it when I go to another tab and come to the starting tab. How can I make it to refresh it as soon as the content has been changed to another intent?

• How to integrate "basic" website into Zend Framework

  - by Joel

  Hi guys, I have a website that has around 10 pages. Only one of those pages uses Zend (to integrate with Google gData). Right now, it's just all coded into that one page, but I'm wanting to learn how to use Zend Framework. How do you handle basic-relatively static php pages within Zend Framework? Do you just stick the whole individual pages into their own respective views and then have to common stuff in the layout, and not worry about a model and controller for those pages? in general, is MVC accepted and appropriate technology for general "web-design" work?

  hi.. how can I position a div under another element without the rest of the layout is affected of the div element? <div style="margin:20px; padding:10px"> here is a little <span id="test" style="font-weight:bold">test</span> </div> <script> var elm = document.getElementById('test'); var div = elm.appendChild(document.createElement('div')); with(div){ style.position = 'absolute'; style.left = elm.offsetLeft; style.background = '#ffffff'; style.width = '100px'; style.height = '50px'; innerHTML = 'wooop'; } </script> this works in IE but not in FF..

• How to make a slide gesture in a view?

  - by AedonEtLIRA

  I have a grid layout that holds a limited 6 items per screen. This set number is just a base for the app and make it look and feel better so it must stay set to that. To get passed this and to add some flash to the app, I want to animate a style of screen change. For instance, when a finger is dragged left, push the current view to the side and bring the next it, very similar to how a gallery does it, except I would like it to be able to scroll vertical as well. Any help or tutorials will be appreciated ~Aedon.

• Explain to me the following VS 2010 Extension Sample code..

  - by ealshabaan

  Coders, I am building a VS 2010 extension and I am experimenting around some of the samples that came with the VS 2010 SDK. One of the sample projects is called TextAdornment. In that project there is a weirdo class that looks like the following: [Export(typeof(IWpfTextViewCreationListener))] [ContentType("text")] [TextViewRole(PredefinedTextViewRoles.Document)] internal sealed class TextAdornment1Factory : IWpfTextViewCreationListener While I was experimenting with this project, I tried to debug the project to see the flow of the program and I noticed that this class gets hit when I first start the debugging. Now my question is the following: what makes this class being the first class to get called when VS starts? In other words, why this class gets active and it runs as of some code instantiate an object of this class type? Here is the only two files in the sample project: TextAdornment1Factory.cs using System.ComponentModel.Composition; using Microsoft.VisualStudio.Text.Editor; using Microsoft.VisualStudio.Utilities; namespace TextAdornment1 { #region Adornment Factory /// /// Establishes an to place the adornment on and exports the /// that instantiates the adornment on the event of a 's creation /// [Export(typeof(IWpfTextViewCreationListener))] [ContentType("text")] [TextViewRole(PredefinedTextViewRoles.Document)] internal sealed class TextAdornment1Factory : IWpfTextViewCreationListener { /// /// Defines the adornment layer for the adornment.

• Why is this javascript function so slow on Firefox?

  - by macrael

  This function was adapted from the website: http://eriwen.com/javascript/measure-ems-for-layout/ function getEmSize(el) { var tempDiv = document.createElement("div"); tempDiv.style.height = "1em"; el.appendChild(tempDiv); var emSize = tempDiv.offsetHeight; el.removeChild(tempDiv); return emSize; } I am running this function as part of another function on window.resize, and it is causing performance problems on Firefox 3.6 that do not exist on current Safari or Chrome. Firefox's profiler says I'm spending the most time in this function and I'm curious as to why that is. Is there a way to get the em size in javascript without doing all this work? I would like to recalculate the size on resize incase the user has changed it.

• Click Listener not invoked within ListFragment

  - by membersound

  I'm extending a SherlockListFragment, but it should not matter as my question seems to be more general related to Fragments. Now, I implement a simple click listener for my list, but it does not get called. public class MyListFragment extends SherlockListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View v = inflater.inflate(R.layout.list, container, false); v.setOnClickListener(new OnClickListener() { public void onClick(View view) { Log.i("debug", "single click"); } }); return v; } } Is anything wrong with this? //Solution: listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Log.i("debug", "single click"); } });

  Hello everyone , I'd started for about a mouth and I have some problems now :( 1. I create a TabActivity and it has three Activity(tab1,tab2,tab3).I wanna realize that if I press a button in tab1,then TextView in tab2 can be changed.

But some are out of the screen. How can I scroll the screen? 3. Is it possible that TextView in Tablelayout can be clicked ? I've sreached there problems on Google for there days but still bother me . Really need help, Thanks :)

• How can I get a Dialog style activity window to fill the screen?

  - by Matthias

  I am using an activity with the dialog theme set, and I want it to be full screen. I tried all sorts of things, even going through the WindowManager to expand the window to full width and height manually, but nothing works. Apparently, a dialog window (or an activity with the dialog theme) will only expand according to its contents, but even that doesn't always work. For instance, I show a progress bar circle which has width and height set to FILL_PARENT (so does its layout container), but still, the dialog wraps around the much smaller progress bar instead of filling the screen. There must be a way of displaying something small inside a dialog window but have it expand to full screen size without its content resizing as well?

• OS X Terminal: Meta key + alt functionality at the same time

  - by abababa22

  Is there a way to use "alt/option" key as a meta key but still be able to use the key to make some characters which need it? For example in my local keyboard layout: @ is alt-2 \ is alt-shift-7 | is alt-7 etc. So if I set alt as meta key, I can't make those characters. On the other hand using "press esc, release esc, press a key" to make meta key sequences makes my hands hurt. Any emacs users with international keyboards who have solved this, please give any tips you might have! :) edit: It appears that I can set alt as meta key and then add these kind of settings in inputrc: "\e2": "@" This works in bash shell but it still won't work with emacs though, so no good.

• Simple interlinear gloss: aligned bilingual paragraph

  - by D W

  An interlinear gloss can be used to layout a translation of a document. http://en.wikipedia.org/wiki/Interlinear_gloss Usually this is done word-by-word or morpheme-by-morpheme. However, I would like to do this in a different way, translating entire paragraphs at a time. http://www.optimnem.co.uk/learning/spanish/three-little-pigs.php For now I am not interested in taking into account the order of words or phrases that change order between languages. That is, I don't mind if the words in the paragraph are not aligned or if the length of one paragraph is much longer than the other, causing an overhanging line. As far as I can tell, the following packages do not meet my needs: covingtn.sty cgloss4e.sty gb4e.sty lingmacros.sty - shortex

• Which reporting tool would you recommend?

  - by grady

  Hi, I have some reporting functionality in my app and I want to improve it a bit. Its only SQL in a XML file which is read by some parser. There can be some params for that SQL and when its parsed and the params are injected, it is executed against my DB (SQL Server). I want to improve that a bit so that the results look better and are more flexible. This are the most important points I need to have: subtotals layout that can change dynamically according to settings in DB (like logo, slogan) possibility to use the same report template for several customers (same fields, but different logos,colors, slogans etc.) should run from an ASP.NET application It should be as dynamic as possible. I know of Crystal Reports and the Microsoft Reporting Tool. Are there any others that might be of interest and are my above points possible at all? Thanks for some ideas and hints :-)...

• Web UI prototyping tools

  - by AlexKelos

  Can anyone recomend me a simple web UI prototyping tool, so I could quicky prototype the look of a my web site. I have tried to use MS Visio for this, but found it very "user un-friendly". What I really need is to be able quicky sketch the layout of the page, put some links, images and buttons on in, play a little bit with a colors (CSS), and it would be great it this tool could support navigation between the pages - but it is not essential. I would rather consider a low-cost or an open-source solution, since I am not a web designer and not going to use that tool on a daily basis.

• ExtJS (4.0) dynamic / lazy loading

  - by Paul

  Given a border layout with a west (navigation) and a center region. Let say I click on topic A in the west region, I want to replace (replace as in 'delete last topic') the center region with 'extjs' program code named topic_a.js I succeed in loading with this code: dynamicPanel = new Ext.Component({ loader: { url: '/www/file.htm', renderer: 'html', autoLoad: true, scripts: true } }); var oMainContainer = Ext.getCmp('maincontainer'); oMainContainer.show(); oMainContainer.add(dynamicPanel); But calling this the second time 'adds' things up in the center region and of course fails short in 'deleting', what would be a good approach?

• Displaying conditional amount of fields in UI (Android)

  - by Sochin

  I am using layout xml documents for my ui controls. I need to create and remove these controls (input fields) on the fly, based on how many results I get back from my database. For each group, there can be 0..* fields and these are prepopulated from the database. Also, it would be good if I can invoke a method to create an additional field; something like the address book, where you can click + or - to add or remove a phone or other detail. In a "psuedo" style, I'm guessing something like this: Check database - How many of X are there [y]? Create Y fields. The user may then add new fields, so once I click submit i need to apply all of that to database. Any examples or hints greatly welcomed. Hope this make sense! :)

• A non-ugly way to persist dialog contents across orientation changes?

  - by alex

  So I have a managed AlertDialog with a number of EditTexts & separate portrait + landscape layouts. The user opens the dialog in portrait mode, enters some text and then all of a sudden decides to pop out the keyboard. Now, I need to remove the dialog and recreate it for the changed layout persisting the text entered. What I can think of is getting references to the EdiTexts in onPrepareDialog(..), then getting the actual text in onConfigurationChanged(..), then removing the dialog, then showing it again, then populating it. Rather ugly, huh? Are there any better options?

• How to deal with multiple screensizes + dynamic controls in Android?

  - by chobo2

  Hi I am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions. I read the tutorial on the android site and still unsure how to do it. First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files. So I am not sure how to android to re size dynamic controls based on the screen size. I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do. So is there some other way to do it that is considered good practice?
