• iPhone SKD make the iPod controller appear

  - by nico

  Hi all, It's been a while I'm consulting stackoverflow, but this time I didn't find any answer :( My question is quite simple :) On an iPhone/iPod touch, play music. Double tap the home button while the music is playing. You will see appear a popup with the play/pause/next/previous buttons and a volume control. Do you know if it's possible to make this popup appear programmatically ? I mean, I would like to add a button in my app that will display the popup, avoiding the user to double tap the home button (most of them doesn't know this shortcut). Thank you in advance !

• Restricting deletion with NHibernate

  - by FrontSvin

  I'm using NHibernate (fluent) to access an old third-party database with a bunch of tables, that are not related in any explicit way. That is a child tables does have parentID columns which contains the primary key of the parent table, but there are no foreign key relations ensuring these relations. Ideally I would like to add some foreign keys, but cannot touch the database schema. My application works fine, but I would really like impose a referential integrity rule that would prohibit deletion of parent objects if they have children, e.i. something similar 'ON DELETE RESTRICT' but maintained by NHibernate. Any ideas on how to approach this would be appreciated. Should I look into the OnDelete() method on the IInterceptor interface, or are there other ways to solve this? Of course any solution will come with a performance penalty, but I can live with that.

• How do I create an empty file in emacs?

  - by Singletoned

  How can I create an empty file from emacs, ideally from within a dired buffer? For example, I've just opened a Python module in dired mode, created a new directory, opened that in dired, and now need to add an empty __init__.py file in the directory. If I use C-x C-f __init__.py RET C-x C-s then emacs doesn't create the file because no changes have been made to it. I would have to type in the file, save it, delete my typing and then save it again for that to work. Thanks

• How to get a 3D picture in an iphone app?

  - by wolverine

  In an application, i saw that they used to display pictures of vehicles. But what was amazing was when we touch and swipe in that picture, it rotates in 3d way left and right. And from the front view we can rotate and get to see its back view also. It is a very good feature and i was trying to replicate it. But couldnt get an idea of how and where to start. My doubts are Whats the actual format of the thing, it surely isn't a picture. How do they get to rotate it? Could someone give me an idea where i should start or where I should look upon?

• How to run a .class file in Windows 7 OS?

  - by jNoob

  Hi, This is probably a stupid question, but how do I run a class file on windows 7? I usually create my own .java files and then use a basic IDE (with JDK6) to compile it to a class and run it automatically. My professor gave a .class file that we are supposed to play with extensively but I have no idea how to to run it here. Note that I cannot run it by typing: java classname.class because it contains gui stuff especially buttons and such. If I do the above I get the following error: java.lang.NoClassDefFoundError: Test1/2/class Caused by: java.lang.ClassNotFoundException: Test1.2.class at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) Could not find the main class: Test1.2.class. Program will exit. Exception in thread "main" Any help would be highly appreciated. Thanks.

• How do you increase Internet Explorer 7's "Select as you type" timeout for comboboxes?

  - by Iain Fraser

  In Internet Explorer 7, you can select options from comboboxes by typing the first few letters of the value you're looking for. However, some people in our organisation are a bit slow and can't type their selection quick enough, with the result that the timeout is triggered and the "select as you type" process starts all over again. Example: If I type A-R-M-A (looking for Armadale) then wait half a second and type D, I'll get selections beginning with the letter D. What I want to do is increase this timeout to allow for slow typers. (We're in a corporate environment so rolling out these changes to all machines won't be a problem).

• Determine if a subview is visible in a UIScrollView

  - by Jools

  Hi all, I've added a view to my app, that contains a UIScrollView, with a number of UITextViews in it's content view. This works perfectly on OS 3.0 and up, but when I test it on my 2.2.1 iPod touch, there is a UITextView bug that stops any text views automatically updating their content when they are scrolled into view - so you have to send them the setNeedsDisplay message. However, I only want to do this when they start to become visible during the scroll - how do I determine, in the UIScrollView's scrollViewDidScroll delegate method, whether a UITextView is visible in the UIScrollView's frame? Ta. Jools.

• Finding vars from dynamically created namespaces in clojure

  - by Tom Crayford

  The following test fails: (ns clojure_refactoring.rename-fn-test (:use clojure.test)) (deftest test-fn-location (in-ns 'refactoring-test-fn-rename) (clojure.core/refer-clojure) (defn a [b] (inc b)) (in-ns 'clojure_refactoring.rename-fn-test) (is (not= (find-var 'refactoring-test-fn-rename/a) nil)) (remove-ns 'refactoring-test-fn-rename)) That is, find-var (of a var I've just created, in a namespace I've just create) returns nil. This behaviour doesn't happen at the repl, where typing out the steps of the test works just fine. Am I doing something wrong, or is this just something that doesn't work in clojure right now?

• Capistrano deploy:migrate Could not find rake-0.9.2.2 in any of the sources

  - by Kyle

  My Capistrano deploy:migrate task is set to run a simple rake db:migrate command, as follows: env PATH=/home/user/.gems/bin sh -c 'cd /home/user/app/releases/20121003140503 && rake RAILS_ENV=production db:migrate' When I run this task during an ssh session manually it completes successfully. However when I run from my local development box, I receive the following error: ** [out :: app] Could not find rake-0.9.2.2 in any of the sources I am able to locate my rake gem by typing which rake via ssh (/home/user/.gems/bin/rake) and rake --version gives me "rake, version 0.9.2.2," so I don't understand why this command fails via Capistrano?

• Develop iPhone application remotely?

  - by ANE

  4 java developers are new to iPod Touch/iPhone app development. They have an idea for an app. They have never used Xcode or Macs before. Instead of spending money for a new iMac or Mac Mini for each of them, my boss would like to sell them a $999 Apple server, hosted at a facility connected a single T1 line, and have all 4 people work remotely in Xcode. Is this feasible? Is anyone doing anything like this? Specifically, is 1 T1 enough for realistic remote app development? Would they have to work in black & white via Logmein or Gotomeeting to get decent speed? Can four people work remotely together on an Xcode project at the same time? Do they absolutely need their own Macs to connect their iPod Touches or iPhones physically to, or can they connect to their existing PCs with iTunes and install their in-development apps that way?

• touchesEnded:withEvent: from UIScrollView First Responder

  - by Matthew Mitchell

  I've made a UIScrollView the first responder. I need to maintain touch events to a touchesEnded:withEvent: method on a view behind it. I've tried using the nextResponder method and that failed. I've tried forwarding touchesEnded:withEvent to the view behind it and that fails. How do I get this to work? The UIScrollView wont work unless it is the first responder or gets events some other way. Thank you for any help. Shame Apple's documentation and APIs are terrible in areas.

• Delete/move a UITableView row that's attached to a web service.

  - by Kevin L.

  Deleting or moving rows for a UITableView that is backed with local data (e.g., NSArray) is easy and instantaneous: Remove the value from the array. Call deleteRowsAtIndexPaths:withRowAnimation:. Profit! But my table view communicates with a web service, which means once the "Delete" button on that row gets tapped, I have to forward a request on to the server (via ASIHTTPRequest, of course), get the response, and then tell the table view to run its little delete-row animation, all with a few seconds of latency in between. From a high-level, what's the best way to do that? Throw some callback selector into ASIHTTPRequest's userInfo dictionary? KVO? Bonus points for some nice UI touch, like some kind of spinner on the soon-to-be-deleted cell.

• Post wall message on facebook account

  - by Zeroshade

  Hello, I am trying to implement some functionality in a blackberry app, that I saw in other application. Basically it's a window that has a message, and a Facebook icon. When you click on the icon it launches a new window, this window asks the user for permissions(user and password), and then the message is posted in the user's wall. So my question is how can I replicate that?. I have been looking at the graph api, but I just can't figure out how to do all of this in one step. I mean just typing the url in the browser, and some post data. Thanks a lot.

• Objective C: Using UIImage for Stroking

  - by SeongHo

  I am trying to apply a texture for my brush but i'm really having a hard time figuring how it is done. Here's the image of my output. I used an UIImage that just follows the touch on the screen but when i swipe it faster the result is on the right side "W", and on the left side that's the result when i swipe it slow. i tried using the CGContextMoveToPoint and CGContextAddLineToPoint i don't know how apply the texture. Is it possible to use UIImage for the stroke texture? Here's my code UIImage * brushImageTexture = [UIImage imageNamed:@"brushImage.png"]; [brushImagetexture drawAtPoint:CGPointMake(touchCurrentPosition.x, touchVurrentPosition.y) blendMode:blendMode alpha:1.0f];

• Safe ASCII char to replace whitespace before storing

  - by AngryWhenHungry

  My code passes a big bunch of text data to a legacy lib, which is responsible for storing it. However, it tends to remove trailing whitespace. This is a problem when I read the data back. Since I cannot change the legacy code, I thought about replacing the all spaces with some uncommon ASCII character. When I read back the text, I can replace them back. Is this a bad idea, considering that I cannot touch the legacy storage code? Which character can I use as a substitute? I was considering some char upwards of 180. There will only be spaces - no tabs or newlines - in the data. The data is alphanumeric, with special characters.

• Repeating characters in VIM insert mode

  - by Cthutu

  Is there a way of repeating a character while in Vim's insert mode? For example, say I would like to insert 80 dashes, in something like emacs I would type: Ctrl+U 8 0 - The only way I know how to do it in VIM is to exit normal mode for the repeat argument, then go back into insert mode to type the dash, then exit to insert the actual dashes, AND then go back into insert mode to carry on typing. The sequence is a really long: <ESC> 8 0 a - <ESC> a It would be nice not to switch in and out of modes. Thanks

• Javascript: setTimeout() - help needed

  - by ilkin

  Hi guys, I'm currently doing a highlighting function on a webpage and im using the jquery plugin for that. My code looks like this: var input = function() { var matchword = $('#searchbox').val(); if(matchword != "") { $('body').removeHighlight(); $('body').highlight($('#searchbox').val()); } } $(document).ready(function() { $('#searchbox').keyup(function() { setTimeout("input()", 2000); }); }); It works fine if there is not so large amount of data on the page. But in case of large amount of data on the page the whole process is slowing down which causes that inputbox is freezing untill the letter is hightlighted. So the typing is not smooth. I tryed to use a setTimeout but it seems doesnt help. Any ideas?

• Google Adword not working /conversion.js not found

  - by Jed

  I'm currently working on a wordpress site. My task is just to add the conversion script in a thankyou page. I added the script here: http://www.livingedge.co.nz/thanks-for-getting-in-touch/ , unfortunately does not work. It says that a conversion.js was not found. See the attached screenshot: http://screencast.com/t/52ixQUzHKNxZ I added the conversion script on the footer put it in a conditional so that it will load only on the thakyoupage. I'm new to this and can't figure out what would be the possible cause of such problem. I tried adding the script in the header, on the page editor, on a form redirect. Q: What could be the possible cause of this issue?

• CodeMirror Dynamic Syntax Validation

  - by rawr

  Been trying to decide between using CodeMirror or Ace editor. I've been leaning towards CodeMirror, however there's one feature of Ace that I really like and that is how it does syntax validation. So as I'm typing there can appear a warning or error icon in the left gutter area beside the line number, and when I hover over it it gives me a little description. Is there any way to get this functionality in CodeMirror? Specifically, I'm using the css mode for CodeMirror. It'd also be nice to be able to add in my own custom validation. Thanks.

• Notepad++ Move Caret Outside Bracket

  - by marknadal

  I've searched everywhere and can't find an answer to something incredibly simple and useful for Notepad++. When using autoclose, the cursor gets stuck inside, which is good until I've finished typing the parameters. How do I get the caret to jump outside of the currently nested autoclosed element? Regardless of it being (), {}, [], "", '', ? CTRL+B does does something similar, but it goes to the inside of the left bracket first, and then to the outside of the right bracket, which is where I want to be. This only works for brackets though, not tags and qoutations Hitting CTRL+B twice is cumbersome and manually hitting "right arrow" requires too much hand motion while coding. And finally, is there anyway I can map this to "SHIFT+Space"?

• How to pass parameters with spaces via cstdlib system

  - by buchtak

  Hi, I have this windows console app which takes a file, do some calculations, and then writes the output to a specified file. The input is specified in "app.exe -input fullfilename" format. I need to call this application from my C++ program, but I have a problem with spaces in paths to files. When I call the app directly from cmd.exe by typing (without specifying output file for clarity) "c:\first path\app.exe" -input "c:\second path\input.file" everything works as expected. But, when I try using cstdlib std::system() function, i.e. std::system(" \"c:\\first path\\app.exe\" -input \"c:\\second path\\input.file\" "); the console prints out that c:\first is not any valid command. It's probably common mistake and has simple solution, but I have been unable to find any. Thx for any help.

• Is there any way to get Visual Studio 2008 to update .net style comments automatically?

  - by Jon Cage

  I've been writing a lot of VC++ 2008 / CLI software recently and am using the C#/CLI style documentation: /// <summary> /// Function the does stuff /// </summary> /// <param name="someParam">Specifies some option</param> /// <returns>true if it worked</returns> bool DoStuff( bool someParam ); I find myself re-typing those blocks quite frequently and frankly, it's getting repetitive. Is there any way to get Visual Studio to create / update those blocks automatically as you create new function definitions or update existing definitions?

• Clojure: using *command-line-args* in the script rather than REPL
