• .focus() doesn't work on an input while orher attributes works

  - by Sirber

  I have a classic table / thead / tbody structure, which I add a line at the end of the tbody. The line contains only an input element. The code works in Firefox 3.6 but not in Chrome v5 or IE8. I'm using jQuery 1.4.1. Does not work: $("#" + AJAX_ID).parent().find('tr:last > td:nth-child(2) > input').focus(); Does work: $("#" + AJAX_ID).parent().find('tr:last > td:nth-child(2) > input').css('background-color', 'red'); even setting an ID on the input, and using document.getElementBuId('id').focus() doesn't work. Thank you!

• Real time updates in php for a pbbg. (Php, JavaScript, and html)

  - by Darknesschaos

  I am trying to create a PBBG (persistent browser based game) like that of OGame, Space4k, and others. My problem is with the always-updating resource collection and with the building times, as in a time is set when the building, ship, research, and etc completes building and updates the user's profile even if the user is offline. What and/or where should I learn to make this? Should it be a constantly running script in the background Note that I wish to only use PHP, HTML, CSS, JavaScript, and Mysql but will learn something new if needed. Cron jobs or the Windows equivalent seem to be the way, but it doesn't seem right or best to me.c

• Need to override cascade style

  - by WillingLearner

  i have a style : .window .div { border:medium solid #000000; height:150px; background-color: #0099FF; } and then i have another style: #NewDiv { font:Arial, Helvetica, sans-serif; font-size: 24px; height: 20px; border-bottom-width: medium; border-bottom-style: solid; border-bottom-color: #000000; } I need to put a #NewDiv div tag inside of window .div, BUT... #NewDiv must retain its own styling while sitting inside of window .div div tags. How do I do this? Currently when I try, #NewDiv takes on the same styling as window .div when i place it inside of it and i dont want that at all. Any suggestions?

• Sharepoint 2010 search: How to modify search query before submit (programmatically?)

  - by palgo

  Hi, I'm making a custom search box Web Part, similar to the OOTB Web Part from SharePoint (SearchBoxEx class). I'm interested in modifying the search query with additional text before it is submitted, based on a custom checkbox added on the Web Part. Any help on how I can achieve this? UPDATE: I've used the AppendToQuery and AppQueryTerms properties, but this will rewrite the text in the search box as well. I'm interested in passing the values "in the background", maybe as an extra parameter. Point is that the query modification should happen without the user seeing it explicitly.

• How to ensure project management questions get answered

  - by Chuck Vose

  Background: On a new project I've found myself 3 levels removed from my actual source of information. I report to my PM, who reports to our contractor, who reports to the actual client. Getting answers to questions has become something of a problem and I'm curious to know what people recommend. Needs: I'm trying to find a technology or disciplined strategy that will assist me in ensuring that the questions I'm asking are getting answered: Correctly without much modification of the original question Quickly so the original context isn't lost Completely so that if a question is deferred I don't forget about it. Does anyone know of a software suite that assists in this matter or do you have any personal discipline strategies that worked for you? Thank you for the guidance

• Is facebook Data Store API available, or a similar/supported persistence mechanism?

  - by jdk

  Question Is there a facebook entry point to a Data Storage mechanism, or should I consider alternatives: What are my alternatives to persist some state information away from my server? ... Background The facebook Data Store Admin tool is made available in a facebook App's Settings (through a link) for the developer to choose as seen here (continue reading below): However when I visit the DataStoreAdmin link nothing works (i.e. clicking the buttons to define the data store types and objects does nothing - I have tried different browsers). The Wiki page for Data Store API hasn't been updated recently and the second last update says the beta Data Store was taken offline. It seems odd the link would be readily available to Apps if the technology is defunct.

• Performing periodic audits and best practice

  - by DTown

  I'm doing a windows form and would like an audit task to happen every 30 seconds. This audit is essentially checking a series of services on remote computers and reporting back into a richtextbox the status. Current I have this running in an endless background thread and using an invoker to update the richtextbox in the main form. Is this best practice? If I made an endless loop in my main form that would prevent any of my buttons from working, correct? I'm just curious if every time I want to create a periodic audit check I have to create a new thread which checks the status or file or what have you?

• IE 8 and text fading

  - by DMIL

  I have a problem with fading text in IE 8, 7 and 6 (obviously). The text has a black outline during the animation that completely ruins the effect. Is there a workaround? I've read a bunch of answers about this problem and none made sense. Please take a look at this simple jsFiddle http://jsfiddle.net/LhSK7/ in IE 8, and show me how to fix it if possible. Edit: screenshot of the problem: http://i43.tinypic.com/1z6h1th.png I thought it might be because of the VirtualBox, but all other browsers display it correctly in VirtualBox. Edit #2: the problem can sort of be solved by setting the background color of the element being faded, which while still pretty ugly in IE 8 and below, at least gets rid of the black outline.

• Running Firefox in the Windows service mode

  - by Leonid

  I'm writing a server running as a Windows service that by request invokes Firefox to generate a pdf snapshot of a webpage. I know it is a bad idea to run a GUI program in service mode, but the server nature of my program restricts from running it in the user mode. Running a user-level 'proxy' also is not an option, since there might be no interactive user logged-in on the machine with the server running. In my experiments Firefox successfully produced pdf when the service was running under a user account that was already logged-in. Obviously it didn't work in other cases: for Local System and user accounts that weren't logged-in. Under LocalSystem with 'Allow service to interact with desktop' option enabled I could see the Firefox started that reports that it's unable to find a printer. Since it wouldn't be practical to require an opened user session for the pdf server to run, is there any workaround for this except running the whole thing from a virtual machine?

• Is there a way to hide a row or column in excel without using VBA?

  - by AJ

  I know of several approaches using a macro (VBA) to show/hide columns and rows in Excel, but I cannot figure out or find a way to do this using either a formula or conditional formatting. Of particular interest is Excel 2007 - but I'd be curious to know if someone has managed to do it in any version of Excel. For those who want background, I have a spread of data with dates across the top and labels down the first column. I would like to specify a date window (on another sheet) as two cells with drop down dates (months) which would then show/hide the appropriate columns on the data sheet.

• How do I write a regex that ignores strings starting with a particular prefix, and captures everythi

  - by Mark Rogers

  Background: I'm trying to come up with a regex for a rewrite rule that will take anything that does not start with a particular prefix, and add that prefix to it. But urls that already have the prefix should be rejected by the regular expression (because they already have the url). Example: If the prefix is s1 a string like home will capture the home part. But a string like s1/home, will not capture anything. This way I can add the capture group onto the prefix, so that 'home' will become 's1/home'. I've tried (^s1/), but I'm missing something here, because that rejected 'home' for some reason.

• How to transition from PHP to Python Django?

  - by ggfan

  Here's my background: Decent experience with PHP/MySql. Beginner's experience with OOP Why I want to learn Python Django? I gave in, based on many searches on SO and reading over some of the answers, Python is a great, clean, and structured language to learn. And with the framework Django, it's easier to write codes that are shorter than with PHP Questions Can i do everything in Django as in PHP? Is Django a "big" hit in web development as PHP? I know Python is a great general-purpose language but I'm focused on web development and would like to know how Django ranks in terms of web development.

• How would you code this: Grid-breaking shapes

  - by BeachRunnerJoe

  I'm a person that learns best from example. Currently, I'm diving into the field of Web Development after fifteen years of developing desktop apps. I'm still getting used to all the web technologies used for developing modern web sites and everywhere I look, I see cool little UI elements and question how they're implemented. So I thought I'd ask you, the web experts...the wexperts :) What are some straight forward or creative ways you could code this grid-breaking arrow... The basic layout for this page looks like... What would the html/css code look like? Would you split the image into multiple images or could you use a single image? I'm sure this is a really simple concept and it completely boggles me. I'm sorry if this is a strange question, remember I'm a noob! :) Thanks in advance for all your help! Here's a link to the original tutorial where I found these images

• iPhone: different icon for homescreen and App Store

  - by arne_

  I would like to know if the app icon on the iPhone can be slightly different than the one shown in a large version in Apple's App Store. It was discussed in short here: http://stackoverflow.com/questions/28551/tips-for-a-successful-appstore-submission/266657#266657 But I wanted to make sure if anyone has more experience with that. To give an example: The New York Times has many words incorporated in its app icon (see http://itunes.apple.com/de/app/nytimes/id284862083?mt=8). Would it be okay to have a full black colored background without the words in the small/homescreen version of the icon?

• iOS UITableViewCell UIImageView setting on different conditions

  - by chis54

  I have an app that has a UITableView and in my Cells I have UIImageViews and UILabels that change images/textColors for a day theme and a night theme (trying to be automatically set). My issue is that I set the images and colors when the table is populated with cellForRowAtIndexPath and its during the day "theme", then if I reopen the app hours later in the night "theme" and the app is still in the "background" and not needing to be reloaded (ie viewDidLoad doesn't fire), the day "theme" shows until I scroll the UITableView and then the night "theme" shows when new cells are brought into view by scrolling. How should I set the objects in my cells when changing around time of the day? I was thinking to use an NSTimer, but I'm not sure how to update the objects in my cells. I was also thinking about using the appropriate methods in the AppDelagate to set things in motion, but is there a way to force reloading the TableView? Any suggestions?

• Is the development stack of java/spring/hibernate/eclipse/tomcat/mysql riddled with config hacking?

  - by Blankman

  From a M$ development perspective, using things like vs.net/c#/asp.net/asp.net mvc/sql server, things are pretty much smooth. (Obviously for someone coming from a microsoft background like me). Now I love the idea of open source, linux and terminal servering into the computer and doing things via the command line, no license issues really, etc. I've tried firing up eclipse etc., but I always seem to get stuck on some configuration issue or another. Does it get easier or is it just the territory when you are dealing with the java stack?

• What are the requirements to consider someone as a Software Engineer? Is it just a job title? [close

  - by mike

  I am employed as a Software Engineer with a background in C# and .NET. I am trying to interface with an web API. I asked for help because I didn't know to connect to it or handle the results. Someone told me that I shouldn't consider myself a Software Engineer because I didn't know to how to do it. They said the API was well documented, required no authentication, and returned XML that I could easily parse. They said the documentation should be enough to figure out how to use the API. Isn't having a job title of Software Engineer the only consideration for being a Software Engineer?

• IDisposable, does it really matter

  - by adrianm

  Coming from C/C++ a long time ago I still have a habit of ensuring that all resources are cleaned up correctly. I always ensure Dispose is called on IDisposable classes and implement Dispose patterns in my classes containing disposable objects. However, in my environment I'm more or less the only one doing this. Others just don't understand what I'm doing and think my code is more difficult to understand. They just create database connections, open streams etc without calling Close or Dispose. Sometimes they set a local or member variable to "Nothing" at the end of a method (guess their background). My problem is that their code works just as well as mine. Code that over time creates thousands of database connection objects just works. So, ignoring any arguments about code correctness, following guidelines etc, does IDiposable really matter? Has anyone actually ran out of resources from not Disposing objects?

• Store data in Ruby on Rails without Database

  - by snowmaninthesun

  I have a few data values that I need to store on my rails app and wanted to know if there are any alternatives to creating a database table just to do this simple task. Background: I'm writing some analytics and dashboard tools for my ruby on rails app and i'm hoping to speed up the dashboard by caching results that will never change. Right now I pull all users for the last 30 days, and re arange them so I can see the number of new users per day. It works great but takes quite a long time, in reality I should only need to calculate the most recent day and just store the rest of the array somewhere else. Where is the best way to store this array? Creating a database table seems a bit overkill, and i'm not sure that global variables are the correct answer. Is there a best practice for persisting data like this? If anyone has done anything like this before let me know what you did and how it turned out.

  First of all apologies for the below question. Am from a Testing background for the past 8 years and very novice to Jmeter. I went through the Jmeter site, and ran a sample recording using the jmeter.apache.org site and it went fine. I want to test my knowledge and understanding. So, I did the following way. Created a thread group. Added a config element HTTP Default Requests with server name as mail.google.com. Added a Sampler as HTTP request, set the METHOD to POST and gave the username and password, and i ran the test. When i see the Results Viewer, i could see the login page of gmail, I need to know how to pass my username and password and simulate the clicking of Submit button and getting the next page. Please help, am very new and will really appreciate if it's explained as simple as possible.

• How do you escape parentheses in a Binding indexer

  - by Chris S

  I have the following XAML: <Grid x:Name="LayoutRoot" Background="White" DataContext="{Binding Source={StaticResource MyDataKey}}"> <TextBox Name="_myId" Text="{Binding MyDictionary[(Textbox.Name)]" /> </Grid> But it thinks the key in my dictionary is called "(Textbox.Name)", instead of "_myId". The format below works, where I have a property in my class called "_myId": <TextBox Name="_myId" Text="{Binding (Textbox.Name)" /> I've tried using ^ and \ to escape the brackets. Is this syntax supported? I'm trying to avoid duplication of the name in two attributes.
