• iPhone - In App Purchase questions

  - by diwup

  Hey guys, Merry Christmas. I have two questions on In App Purchase. iAP application process: do I need to submit my iAP items applications, wait for Apple's responses, then build my app accordingly, or, I can just create some iAP items, build them into my app, then after everything's done, submit my binary to Apple? Intermediary currency: on Apple's documentation I found these sentences: "You may not offer items that represent intermediary currency because it is important that users know the specific good or service that they are buying." However, I found a few apps on the App Store offering its users with different kinds of intermediary currency. I'm confused. Is this a gray area in which we developers can play some tricks? Thanks in advance. Di

• UIViewController: setToolbarItems vs navigationItem

  - by Paul Sanwald

  my application has a UIViewController subclass which is being managed by a UINavigationController. In the viewDidLoad of my UIViewController subclass, I was attempting to add a UIBarButtonItem to the toolbar like this: settingsButton = [[UIBarButtonItem alloc] initWithTitle:@"Settings" style:UIBarButtonItemStylePlain target:self action:@selector(viewSettings:)]; [self setToolbarItems:[NSArray arrayWithObject:settingsButton]]; this wasn't working out for me, so after some googling around, I tried this: [[self navigationItem] setRightBarButtonItem:settingsButton]; which worked out fine. from reading the UIViewController documentation, I'm still confused about why setToolbarItems wasn't working. I verified in the debugger that the button was in the toolbarItems array in the viewDidAppear method. the button itself just wasn't appearing on my toolbar. so, my question is, why didn't setToolbarItems work for me in the first code snippet? I don't have the toolbar configured in my xib for this view controller at all, if that makes a difference.

• Querying Same Lookup Table With Multiple Columns

  - by dmaruca

  I'm a bit confused on this. I have a data table structured like this: Table: Data DataID Val 1 Value 1 2 Value 2 3 Value 3 4 Value 4 Then I have another table structured like this: Table: Table1 Col1 Col2 1 2 3 4 4 3 2 1 Both columns from Table1 point to the data in the data table. How can I get this data to show in a query? For example, a query to return this: Query: Query1 Column1 Column2 Value 1 Value 2 Value 3 Value 4 Value 4 Value 3 Value 2 Value 1 I'm familiar enough with SQL to do a join with one column, but lost beyond that. Any help is appreciated. Sample sql or a link to something to read. Thanks! PS: This is in sqlite

• execute javascsript for loop alternately forward and backward

  - by Stiff Mittens

  What I'm trying to do is iterate through an array in chunks, alternating the direction of iteration from chunk to chunk. Confused? So am I. For example, if I want to loop thru an array with 25 elements, but I want to do it in this order: 0, 1, 2, 3, 4, 9, 8, 7, 6, 5, 10, 11, 12, 13, 14, 19, 18, 17, 16, 15, 20, 21, 22, 23, 24, what would be the most efficient way of doing this? I'm looking for something scalable because the array I'm working with now is actually 225 elements and I want to traverse it in 15 element chunks, but that may change at some point. So far, the only method I've figured out that actually works is to hard-wire the iteration order into a second array and then iterate through that in the normal way to get the indices for the original array. But that sucks. Any help would be greatly appreciated.

• meaning of (\/?) in regex / is (\w+)([^>]*?) a redundancy?

  - by thomas

  this regular expression should match an html start tag, I think. var results = html.match(/<(\/?)(\w+)([^>]*?)>/); I see it should first capture the <, but then I am confused what this capture (\/?) accomplishes. Am I correct in reasoning that the ([^>]*?)> searches for every character except > = 0 times? If so, why is the (\w+) capture necessary? Doesn't it fall within the purview of [^>]*?

• Two Column Theme, Help, to make both columns seperately Scrollable.

  - by Michael macDonald

  Hey, I am not sure what to do on this one, I'm not a programmer, but trying to learn CSS as this is how the theme I am using was coded in. I've gotten quite far on my own, but this one stumps me Its two column Theme... As far as I have been able to get, I can use the following: #left { width: 235px; padding: 10px; margin-left: 20px; position: fixed; line-height: 15px; If I change the position to Absolute, The whole page scrolls, If I leave it at Fixed, and add lets say, a Twitter feed, or other type of text that takes me past its reading where you would normally scroll, Its just cut off, cannot get to it, hightlight or scroll.. I've also toyed with the idea, of changing the theme to a 3 column theme, but Again, not a programmer, and i'd be really confused. anyhelp would be great... My Website is at 99lessoxygen.tumblr.com, code was found from http://nigredotheme.tumblr.com

• Spreading dynamic with community structure

  - by YogurtFruit

  I have a data set which I hope to simulate the spreading dynamic with community structure. The steps I follow is import the data to a complex network with Networkx partition the network into some modules which are known as communities simulate the SIS model and draw plots with and without communities. Something confused me between step 2 and step 3. After partitioning, I get some communities which contains nodes number. The community numbers and nodes numbers are the only input to step 3, and how I simulate SIS with and without communities?

• Specifying routes by subdomain in Express using vhost middleware

  - by user730569

  I'm using the vhost express/connect middleware and I'm a bit confused as to how it should be used. I want to have one set of routes apply to hosts with subdomains, and another set to apply for hosts without subdomains. In my app.js file, I have var app = express.createServer(); app.use...(middlware)... app.use(express.vhost('*.host', require('./domain_routing')("yes")); app.use(express.vhost('host', require('./domain_routing')("no")); app.use...(middlware)... app.listen(8000); and then in domain_routing.js: module.exports = function(subdomain){ var app = express.createServer(); require('./routes')(app, subdomain); return app; } and then in routes.js I plan to run sets of routes, dependent on the subdomain variable passed in is "yes" or "no". Am I on the right track or is this not how you use this middleware?

• Should I allow my clients to open tickets/access trac?

  - by Mark

  I just installed trac for this project I'm working on, since it's turned out to be a bit bigger than I anticipated. I've added a bunch of tickets with my clients requests which come in the form of emails, phone calls, and meetings. I've also added some stuff I know needs to be done/fixed but they haven't specifically requested. Should I grant them access to trac so they can submit the tickets themselves so I don't have to keep translating (words into tickets) for them? They're very non-technical, so I'm not sure how well it would work; they might open tickets and not provide enough detail, or get confused by all the different fields. If your answer is "no", should I at least let them view the tickets, so they can see what I'm working on, what's been done, hasn't been done? So they can stop calling me to say "xxx doesn't work" when it's already a ticket? (Not that this would work, but I could at least respond "see ticket #42")

• IPhone: Controllers, Delagates, DataSources, etc all in one class?

  - by MLS

  Hi All, I am learning iPhone programming. I am starting with a simple example of displaying recently used documents in a UITableView. What I am confused about is why do I need to have several classes and why cant I just use one? Example, My class is called RecentFileList. I need to implement controller, delegate and datasource as well as the actual table view. Can't I just do this all in my RecentFileList Class versus having to create a RecentFileListDelegate RecentFileListController, RecentFileListDataSource class, etc, etc. Related to this can one define a class like: @interface FileListView : NSObject <UITableViewDelegate> <UITableViewController> <UITableViewDataSource { // code } @end or would I just do the work to make my class a delegate and controller in init()?

• Old functions return 'undefined' error once I add a jquery reference

  - by Lapa

  Disregard this question: I've simply confused <script src="..."></script> tag and <script> [some functions] </scipt> tags. I have this function function OnLoad() { ShowHideConfirmAnswers(); return true; } triggered by onload event: <body onload=OnLoad()> It works fine until I add src="jquery-1.4.2.js" to the script element. From this moment I get "OnLoad is not defined" error, and the same happens to every other javascript function.

• About a Class Object

  - by Chicko Bueno

  I have a very basic question about a class object. After the class has been created, we need to create a class object. At this point, I'm a bit confused to make either *object or object. Example: CClass object CClass *object What is the difference both of them? And to access class function i need to use dot '.' and arrow '->'. I know dot and arrow used to access class function, but what is the significant meaning for both dot and arrow?

• How to store and retrieve pictures using PHP?

  - by user1276898

  I am building a webpage using PHP to search within my database. I am able to do a query and get the data to show on my page. I also have a picture that is related to each record. Let's say something like a picture ID for each employee. I am wondering what is the best way to store and retrieve pictures in order to get it show using PHP. Is there a way to store all the pictures in the subfolder like " image" and retrieve the pictures using PHP? I tried to search around on the internet, but I get confused. Also, when I type something in the search box and click the button, is there a way to keep the input in the search box without erasing it? Thank you very much.

• How do I make a DIV stay at the top of the screen no matter ow far down the page my visitor scrolls?

  - by user1289863

  What I'm saying is, I have some extremely long pages on my website, which can make it annoying I've my visitors need to scroll to the top of the page to be able to navigate to another page. I'm not quite sure what I would call this but any Google search that contains the words 'DIV' and 'float' come up with completely unrelated results... What I'm looking to do is create a DIV that stays at the top of the Screen (not to be confused with the page) so that if the user is at the bottom of the page, they can still see the navigation bar just floating at the top of the screen. What I can think of is to position the DIV relative to the position of the screen but I don't know how to code this. I'm happy to use JavaScript (preferably in the form of jQuery), but if you know how to do this using CSS, I would favour your response. This might help: I know a little bit of jQuery and JavaScript and I know a good deal of CSS and HTML. Thanks in advance.

• How should I use try...except while defining a function?

  - by SpawnCxy

  Hi all, I find I've been confused by the problem that when I needn't to use try..except.For last few days it was used in almost every function I defined which I think maybe a bad practice.For example: class mongodb(object): def getRecords(self,tname,conditions=''): try: col = eval("self.db.%s" %tname) recs = col.find(condition) return recs except Exception,e: #here make some error log with e.message What I thought is ,exceptions may be raised everywhere and I have to use try to get them. And my question is,is it a good practice to use it everywhere when defining functions?If not are there any principles for it?Help would be appreciated! Regards

• TypeError: object not callable when making instance

  - by TSM

  I've searched around other threads with similar questions, but I'm not finding the answer. Basically, I have a class: import Android_Class class Android_Revision(object): def __init__(self): # dict for storing the classes in this revision # (format {name : classObject}): self.Classes = {} self.WorkingClass = Android_Class() self.RevisionNumber = '' def __call__(self): print "Called" def make_Class(self, name): newClass = Android_Class(name) self.Classes.update({name : newClass}) self.WorkingClass = newClass def set_Class(self, name): if not(self.Classes.has_key(name)): newClass = Android_Class(name) self.Classes.update({name : newClass}) self.WorkingClass = self.Classes.get(name) I'm trying to make an instance of this class: Revision = Android_Revision() and that's when I'm getting the error. I'm confused because I have another situation where I'm doing almost the exact same thing, and it's working fine. I can't figure out what differences between the two would lead to this error. Thanks.

• Unit tests logged (or run) multiple times

  - by HeavyWave

  I have this simple test: protected readonly ILog logger = LogManager.GetLogger(MethodBase.GetCurrentMethod().ReflectedType); private static int count = 0; [Test] public void TestConfiguredSuccessfully() { logger.Debug("in test method" + count++); } log4net is set up like this: [TestFixtureSetUp] public void SetUp() { log4net.Config.BasicConfigurator.Configure(); } The problem is, that if I run this test in nUnit once, I get the output (as expected): 1742 [TestRunnerThread] DEBUG Tests.TestSomthing (null) - in test method0 But if I press RUN in nUnit.exe again (or more) I get the following: 1742 [TestRunnerThread] DEBUG Tests.TestSomthing (null) - in test method1 1742 [TestRunnerThread] DEBUG Tests.TestSomthing (null) - in test method1 And so on (if I run it 5 times, I'll get 5 repeating lines). Now, if I run the same test alone from reSharper the output is fine and does not repeat. However, if I run this test along side 2 other tests in the same class, the output is repeated three times. I am totally confused. What the hell is going on here?

• mod_rewrite per-dir redirection returning a 400

  - by Eaterrust

  I moved my images directory to a different folder, and now I want to redirect all images requests from that folder to the new one. I do not have access to the main configuraion file, so I'm doing this in a .htaccess. I tried this, and it works:     RewriteCond %{REQUEST_URI} old_dir/.+.(jpg|png|gif)$     RewriteRule old_dir/(.+[^/]+..+)$ $1 [L,PT] But since they have permanently moved, I want to do a proper redirect, so I added the [R] flag, like this:      %{REQUEST_URI} old_dir/.+.(jpg|png|gif)$     RewriteRule old_dir/(.+[^/]+..+)$ $1 [L,PT,R] But the server gets confused, and returns a 400, so I looked at the log file, and this is what happens:     strip per-dir prefix: C:/wamp/www/natrazyle/old_dir/images/banner.jpg - old_dir/images/banner.jpg     applying pattern 'old_dir/(.+[^/]+..+)$' to uri 'old_dir/images/banner.jpg'     rewrite 'old_dir/images/banner.jpg' - 'images/banner.jpg'     add per-dir prefix: images/banner.jpg - C:/wamp/www/natrazyle/images/banner.jpg     explicitly forcing redirect with http://localhost/C:/wamp/www/natrazyle/images/banner.jpg As you can see, the full local path gets added after localhost I know I'm doing something wrong, I just can't figure it out myself. Any help would be greatly appreciated...

  I am looking at try to increment and decrement by three records through a table and present those records. Say if the id '4' is currently active. I want the to be display the ID's and category of 3.2.1 and 5.6.7 from an increment and decrement So far I have: $stmt = $db->query("SELECT id, category FROM test"); $stmt->execute(); while ($results = $stmt->fetch(PDO::FETCH_ASSOC)) { $current = $results['id']; $category = $results['category']; $next = array(array('slide_no' => $current, 'category' => $category)); } print_r($next); Now with this, I am getting back every row in the table. I'm now getting confused on how I could increment and decrement the records by 3 and make sure that the category will also increment correctly. Thank you very much.
