• What you need BEFORE you submit your iPhone app to Apple

  - by Patty

  When submitting a new app to the iPhone app store, which of these are mandatory, and which are optional? (Free apps... or paying apps.) A bank account with direct deposit access. An email address to give out to the public. An email address for Apple to contact me. A support website. A company name. A support phone number for the public. A phone number for Apple to call me. My full name given out to the public.

• database text field databound to a checkbox

  - by Patrick

  I'd like the field to save as a 1 or 0 instead of 'True' or 'False' in the database and i cannot figure out how to do it without manually setting every property when the record is saved. I have to use this a lot in this project and a bit field is not an option. I would like to solve this issue by extending the CheckBox control if possible but i don't know how to change the binding fields value. Any help would be greatly appreciated!

• Are the built-in images in iPhone documented, and is there a list of their names somewhere?

  - by Alex Gosselin

  I discovered somewhat by accident that if you make a UIButton in Interface Builder and type in Plus in the image field, a + image appears for the button. A similar result comes from typing Minus. I am wondering if this is a bug, or if there is some way the poor programmers can access the built-in general GUI images from other apple apps, such as the green +, the red -, the detail disclosure chevron, the big red "Delete Contact" or similarly styled button, etc. Has anyone else encountered this, or know where to access these things in Xcode? It makes sense to me that they should be usable, cause the Apple HIG seems to be all about making things recognizable and intuitive, and using them the way other apps use them.

• A Good Final High School AP Computer Science Programming Project?

  - by user297663

  Hey guys this question might seem very specific but I am in need of some ideas for a project to do for my last month or so in my AP Computer Science class. I've been looking at some college final ideas and a lot of them just seem plain boring. At first I thought about writing a IRC client in JAVA but I wouldn't really be learning anything "new" that would help me in the future. Then I thought about doing IPhone/touch apps (I don't have an adroid phone and I can easily get my hands on an itouch) but I would need ideas to make apps for that. I want to do something that is going to feel trivial and need some explanation but will also help me in the long run learning new concepts in computer science. If you guys could help out I would greatly appreciate it. I really only have a month to do this project so try to keep the project inside of that range. Also, I don't mind learning new languages. Thanks :)

• How to nest a Location directive inside a virtual host config?

  - by Josh

  I am trying nest a Location directive inside a virtual host config like this: <VirtualHost *:80> ServerName mysite.com DocumentRoot /home/deployer/apps/mysite/current/public ErrorLog /var/log/prod.log <Location "/shop"> DocumentRoot /home/deployer/apps/mysite_shop/current/public ErrorLog /var/log/prod.log </Location> </VirtualHost> What I want to do is go to mysite.com/shop, and point it to another application. Is this possible? Is there another method of doing this? I get an error because apparently Location directives do not accept DocumentRoot. Thanks.

• Mobile Application Upgrade/Update Framework

  - by sharjeel

  I am developing a few mobile apps for different platforms including Blackberry, Windows Mobile, Android and Symbian S60. I want my mobile apps to have the capability of checking for updates before starting and in case a new version is available, prompt the user to upgrade. Moreover in certain cases (like security patches), the user must be forced to update or the app won't work. Surely I can cook some code to achieve the task but I was wondering if there are already existing framework to serve the purpose so that I don't have to re-invent the wheel and test all over?

• How can I try a new language or framework without installing it?

  - by flamingLogos

  With so many languages and frameworks that exist, and with new ones appearing all the time, I don't have the time to download, install, and configure each one to evaluate it. In the past I've run across webapps that allow one to write or paste code into a window, and see the results in realtime in the browser, usually in a tutorial setting. What are your favorite sandbox sites for a given technology? Edit: @fretj provided the link to the excellent Google Code Playground (+1 upvote), but I thought that it was just for experimenting with Google's own apps (Search, Maps, Earth, Language, etc). But it turns out that it contains a few hidden gems: In addition to their apps, you can try out the many Javascript libraries that they host including jQuery, jQuery UI, MooTools, Dojo, and Prototype Scriptaculous. They're all hidden under the Libraries category in the "Pick an API" box. I overlooked the category because I thought it was for an app called Google Libraries. There's also a Javascript category for Javascript itself.

• View controller/NIB architecture for non-navigation application with transitions?

  - by Ben

  I'm tinkering with an app that doesn't use the UINavigation root view control system, so I don't have natural ownership for each app "view". I essentially have two basic views, a document list view, and a document edit view. I'm playing with UIView animation for getting from a selected document to the edit view. I also have a toolbar that exists in both "views". Because I don't have UINavigation running the show for me, I have a tendency to just throw more and more stuff into one NIB and one view controller that owns the whole container. But now I'm trying to figure out how to segue from the document list view to the edit view if the edit view lives inside a different NIB, preserving the toolbar too. Anyone have thoughts or experience on app structures like this? I find the docs lacking on best practices around code/UI structure for anything except trivial one-screen apps or full-on navigation apps. Thanks!

• Creating a Custom Compound Button Bar

  - by vijay

  I have to create a custom compound button bar control in Android like the one here. To create a button bar like this, I am thinking of extending a LinearLayout and add my buttons to it. The buttons have a black background but with a gradient fill; I am not keen on using PNGs since the color of the buttons can change at runtime. How can I get similar effect in Android? Thanks.

• Detect whether certain IIS features are present from InstallScript

  - by Christian Hayter

  I have an InstallScript project written in InstallShield 2010, which, amongst other things, shells out to several .NET MSI installers that install web apps. If any of these web apps are selected for installation by the end user, I need to check for the following optional IIS features from InstallScript code before allowing the install to proceed: ASP.NET (IIS 6+) WCF HTTP Activation (IIS 7+) IIS Metabase and IIS 6 configuration compatibility (IIS 7+) Can anyone point me in the right direction please? Ideally I'm looking for registry values that I can check directly from InstallScript code, but I guess some kind of WMI or COM check would be OK as well. PS: In case it's relevant, we need to support all versions of IIS from 5.1 onwards at this time. If 5.1 support is a problem, we may consider dropping it if we have to.

• Detach many subdirectories into a new, separate Git repository

  - by prisonerjohn

  This question is based on http://stackoverflow.com/questions/359424/detach-subdirectory-into-separate-git-repository Instead of detaching a single subdirectory, I want to detach a couple. For example, my current directory tree looks like this: /apps /AAA /BBB /CCC /libs /XXX /YYY /ZZZ And I would like this instead: /apps /AAA /libs /XXX The --subdirectory-filter argument to git filter-branch won't work because it gets rid of everything except for the given directory the first time it's run. I thought using the --index-filter argument for all unwanted files would work (albeit tedious), but if I try running it more than once, I get the following message: Cannot create a new backup. A previous backup already exists in refs/original/ Force overwriting the backup with -f Any ideas? TIA

• Suppress the HTTP_X_FORWARDED_FOR http header, c# .net C++

  - by Sean

  I'm writing an application in C# that uses proxies. The proxies are sending the HTTP_X_FORWARDED_FOR during HTTP requests, and this is unwanted behavior. I am extending the Interop.SHDocVw axWebBrowser (aka Internet Explorer) control right now, but can take another approach if needed for this problem. Is there some way to suppress this header... can this be done in code, on the proxy server, or not at all?

• ARC, worth it or not?

  - by MSK

  When I moved to Objective C (iOS) from C++ (and little Java) I had hard time understanding memory management in iOS. But now all this seems natural and I know retain, autorelease, copy and release stuff. After reading about ARC, I am wondering is there more benefits of using ARC or it is just that you dont have to worry about memory management. Before moving to ARC I wanted to know how worth is moving to ARC. XCode has "Convert to Objective C ARC" menu. Is the conversion is that simple (nothing to worry about)? Does it help me in reducing my apps memory foot-print, memory leaks etc (somehow ?) Does it has much testing impact on my apps ? What are non-obvious advantages? Any Disadvantage os moving to it?

• Instanciate a class with a given id in ExtJS

  Hello, I would like to know if it is possible to instanciate a class by its id . For example we have a class extending Ext.grid.GridPanel with an id property, is it possible to instanciate the class just knowing his id (which is the component id in this case) ?

• When to use Version Control?

  - by user156814

  I am a lone developer, developing Web Sites/Apps in PHP. I dont work with anybody, I use a framework so I dont create libraries for my apps (most of the time). I have read a lot about Version Control and its benefits, but I dont understand how it would benefit somebody like me. The biggest benefit I can see it having is that if I posted the code on a remote server I could work from anywhere on any computer, but I carry my laptop like I carry my phone so again I dont see much of a reason there. Can somebody please explain to me in a simple manner the reasons for going with a VCS, and give me some good free ones I should try? Are there any hidden benefits/scenarios that you can think of that may sway me in any direction one way or the other. Thanks

• Can a class Extend or Override himself?

  - by EBAGHAKI

  Suppose we have a class. We create an object from the class and when we do the class Extends himself base on the object initialization value.. For example: $objectType1 = new Types(1); $objectType1->Activate(); // It calls an activation function for type 1 $objectType2 = new Types(2); $objectType2->Activate(); // It calls an activation function for type 2 I don't want to use the standard procedure of class extending: class type1 extends types{}

• Sharepoint tools for document version control

  - by notnot

  Does anyone know of any tools for extending the functionality of Sharepoint's existing version control system for Office documents? It'd be great to be able to do branching/merging, or to store versions as "deltas" off the previous to cut down on storage used. Any suggestions at all would be helpful. Thanks in advance!

For the same Apple has mentioned 3 ways, however I am using the method where a Single XCODE proj is used for having 2 targets- iphone & iPad. There are a few queries: two binaries will be created , which I can price differently for selling. Will they need 2 have different certificates from Apple ? My app has Push notifications. So will i require 2 different certificates ?

• Which is the UI technology of the future considering: eye-candy-effect, interactivity (gestures, voc

  - by user193655

  If you had to write a next-gen application, in which on the surface (UI) you need some "futuristic features", by considering the following aspects which is the choice you'd make? 1) eye-candy: cool UI, 3D, Effects, nice graphics, sound transitions... 2) user interaction: not only mouse and keyboard but touch, voice and more.... + user interactivity aspect, which is the technology you'd choose? 3) X-platform: this is to have some X-platform discussion. Of course single platform technologies (as WPF) have may be some more power, anyway in a general discussion considering X-platform as a resource is important 4) available components: of course the coolest technology with no available components is may be an option for a component developer but not for an application developer My question is generic, but anyway * have in mind data-driven apps, not pure multimedia apps, videogames, ....

• Recommended ASP.NET Shared Hosting

  - by coffeeaddict

  Ok, I have to admit I'm getting fed up with www.discountasp.net's pricing model and this annoyance has built up over the past 8 years or so. I've been with them for years and absolutely love them on the technical side, however it's getting ridiculously expensive for so little that you get. I mean here's my scenario: 1) I am running 2 SQL Server databases which costs me $10/ea per month so that's $20/month for 2 and I only get 500 mb disk space which is horrible 2) I am paying $10/mo just for the hosting itself which I only get 1 gig of disk space! I mean common! 3) I am simply running 2 small apps (Screwturn Wiki & Subtext Blog)...so I don't really care if it's up 99% or not, it's not worth paying a total of $300 just to keep these 2 apps running over discountasp.net Anyone else feel the same? Yes, I know they have great support, probably have great servers running behind this but in the end I really don't care as long as my site is up 95% or better. Yes, the hosting toolset rocks. But you know I bet you I can find a similar set somewhere else. I like how I can totally control IIS 7 at discountasp and I can control my own app pool etc. That's very powerful and essential. But anyone have any good alternatives to discountasp that gives me close to the same at a much more reasonable cost point? I mean http://www.m6.net/prices.aspx gives you 10 SQL Databases for $7 and 200 gigs disk space! I don't know about their tools or support but just looking at those numbers and some other hosts I've seen, I feel that discountasp.net is way out of line. They don't even offer any purchasing discounts such as it would be nice if my 2nd SQL Server is only $5/month not $10...stuff like this, to make it much more realistic and fair. Opinions (people who do have discountasp.net, people who have left them, or people who have another host they like)??? But geez $300 just to host a couple DBs and lightweight open source apps? Not worth the price they are charging. I'm almost at a price point that enables me to get a decent dedicated server! I really don't care about beta support. Not a big deal to me.
