• Is this considered as using private functions in iPhone dev, and thus illegal?

  - by user153231

  I'm trying to disable scrolling for a UIWebView and the only way i found is using this way: #import <objc/runtime.h> id scroller = [[Webview subviews] lastObject]; int count; Method *method = class_copyMethodList([scroller class], &count); int i; for (i=0; i<count; i++) { if (strcmp(method_getName(method[i]), "setScrollingEnabled:") == 0) break; } IMP test = method_getImplementation(method[i]); test(scroller, @selector(setScrollingEnabled:), NO); Is this considered to be an illegal way of using the iPhone SDK? Can this cause my application to be rejected for the App store?

• mapping 'value object' collection in (Fluent) NHibernate

  - by adrin

  I have the following entity public class Employee { public virtual int Id {get;set;} public virtual ISet<Hour> XboxBreakHours{get;set} public virtual ISet<Hour> CoffeeBreakHours {get;set} } public class Hour { public DateTime Time {get;set;} } (What I want to do here is store information that employee A plays Xbox everyday let's say at 9:00 13:30 and has a coffee break everyday at 7:00 12:30 18:00) - I am not sure if my approach is valid at all here. The question is how should my (ideally fluent) mappings look like here? It is not necessary (from my point of view) for Hour class to have Id or be accessible from some kind of repository.

• What structure of data use to communicate via tcp/ip in java?

  - by rmaster

  Let's assume I want to send many messages between 2 programs made in java that use TCP sockets. I think the most convienient way is to send objects like: PrintStream ps = new PrintStream(s.getOutputStream()); ObjectOutputStream oos = new ObjectOutputStream(ps); some_kind_of_object_here; oos.writeObject(some_kind_of_object_here); ps.print(oos); I want to send, strings, numbers, HashMaps, boolean values How can I do this using fx 1 object that can store all that properties? I though about ArrayList that is serializable and we can put there everything but is not elegant way. I want to send different types of data because user can choose from a variety of options that server can do for it. Any advices?

• SQL Alchemy: Relationship with grandson

  - by giomasce

  I'm building a SQL Alchemy structure with three different levels of objects; for example, consider a simple database to store information about some blogs: there are some Blog object, some Post object and some Comment objects. Each Post belongs to a Blog and each Comment belongs to a Post. Using backref I can automatically have the list of all Posts belonging to a Blog and similarly for Comments. I drafted a skeleton for such a structure. What I would like to do now is to have directly in Blog an array of all the Comments belonging to that Blog. I've tried a few approaches, but they don't work or even make SQL Alchemy cry in ways I can't fix. I'd think that mine is quite a frequent need, but I couldn't find anything helpful. Colud someone suggest me how to do that? Thanks.

• PHP MySQL New Lines / Whitespaces from textarea

  - by rob_robsen

  I've a problem about whitespaces and new lines at the beginning of a textarea. I send a json string with ajax to the php script. Then I decode the string into an php array (with json_decode). So I have a string in this array with two line breaks at the beginning. If a print the text from the array, the line breaks are there, but if I store the text into the mysql database, the line breaks are gone... Only at the beginning of the string, the line breaks gone... At the rest of the string, the line breaks are ok. Thanks for your answers! rob

• PL/SQL exception and Java programs

  - by edwards

  Hi Business logic is coded in pl/sql packages procedures and functions. Java programs call pl/sql packages procedures and functions to do database work. pl/sql programs store exceptions into Oracle tables whenever an exception is raised. How would my java programs get the exceptions since the exception instead of being propagated from pl/sql to java is getting persisted to a oracle table and the procs/functions just return 1 or 0. Sorry folks i should have added this constraint much earlier and avoided this confusion. As with many legacy projects we don't have the freedom to modify the stored procedures.

• apc cache compression

  - by Massimo

  I want to store some key value. I see memcache api supports on-the-fly compression: memcache_set( obj, var, value, MEMCACHE_COMPRESSED, ttl ) What about apc ? I cannot find any doc. My goal, for example in php : function cache( $key, $value ) { $data = serialize( $value ); if ( strlen( $data ) >= 1024 ) $data = 'z' . gzcompress( $data, 1 ); else $data = '=' . $data; return apc_store( $key, $data, $ttl ); }

• Are there any Objective-C / Cocoa naming conventions for properties that are acronyms?

  - by t6d

  I have an object that models an online resource. Therefore, my object has to store the URL of the resource it belongs to. How would I name the getter and setter? MyObject *myObject = [[MyObject alloc] init]; // Set values [myObject setURL:url]; myObject.URL = url; // Get values [myObject URL]; myObject.URL; or would the following be better: MyObject *myObject = [[MyObject alloc] init]; // Set values [myObject setUrl:url]; myObject.url = url; // Get values [myObject url]; myObject.url; The former example would of course require to define the property in the following way: @property (retain, getter = URL, setter = setURL:) NSURL *url;

This is an E-commerce project and I am looking for something to manage Product and system URL from database. Something Similar like magneto dose. Basically anything after the domain say like domain.com/demo/12/my_iphone so now demo/12/my_iphone will be sent to database for querry and in databases there will be a destination URL which could be productlisting.php?searchstring=iphones so the user will see link domain.com/demo/12/my_iphone but actualy he will be seeing productlisting.php?searchstring=iphones basically demo/12/my_iphone = productlisting.php?searchstring=iphones and tomorrow if the user want to edit demo/12/my_iphone to demo/12/myiphone he can just do so using simple form which will update in the database.

• Cheap Wifi enabled Android or other programmable device

  - by Darran

  Does anyone know of a cheap Android or programmable device that has wifi? I need it for a project for a company that needs a wifi handheld device for the shop floor. Im not too fussed about the language the device uses though Im not really interested in the iTouch as theres no intention to release the app in the app store and I don`t really want to jail break everybodys iTouch. Ideally it would be small , iTouch size for example and relatively cheap $100 or less. Nothing fancy just ability to write a simple UI and have wifi. Voice is not needed. Not too fussed about touch or qwerty keyboard either.

• How? Encrypt and Decrypt user membership passwords in ASP.NET

  - by smdrager

  We are creating a new site using ASP.NET membership provider for user registration and log in. Our old system encrypted user passwords so that we could recover them if we needed to. I am having a great deal of trouble figuring out if it is possible to use ASP.NET membership functions to simply encrypt the password when the user registers and then unencrypt it so I can see it. Documentation for this is neigh non-existant. I know how to configure Web.config to have it store passwords as encrypted ala passwordFormat="Hashed" in the provider and assigning a validationKey in the machineKey, however it seems like the password still gets hashed (though perhaps it is just well encrypted). Either way I cannot decifer how the password can be recovered (by us) if neccessary. Thanks!

• OpenSocial and its usages

  - by Paul Knopf

  I have looked for some explanation on the exact usages for the set of standards known as OpenSocial. I need some clarification if I can use OpenSocial like the following. I would like to create one library used to community with an OpenSocial api for use in my website that will not 'behave' like an application described by common sites like facebook and myspace. I'm not making a myspace of facebook application, I'm creating my own website and I want users to be able to find friends. I would like to allow users to store usernames and passwords for various OpenSocial-supported social networks. I would also like to use the api to sync events from my web site to their specified social network. I would also like to allow my users to view a list of friends and invite them. Is it possible to create one library that supports OpenSocial and simple "point" to and social network that supports it to get a list of friends and etc?

• Download and replace Android resource files

  - by Casebash

  My application will have some customisation for each company that uses it. Up until now, I have been loading images and strings from resource files. The idea is that the default resources will be distributed with the application and company specific resources will be loaded from our server after they click on a link from an email to launch the initialisation intent. Does anyone know how to replace resource files? I would really like to keep using resource files to avoid rewriting a lot of code/XML. I would distribute the application from our own server, rather than through the app store, so that we could have one version per company, but unfortunately this will give quite nasty security warnings that would concern our customers.

• Connect android to database

  - by danny

  I am doing a school project where we need to create an android application which needs to connect to a database. the application needs to gain and store information for people's profiles on the database. But unfortunatly we are a little bit stuck at this point because there are numerous ways to link the application such as http request through apache or through the SOAP/REST protocol. But it's really hard to find good instructions or tutorials on the problem since I can't really find them. Maybe that's cause i'm probably using the wrong words on google. Unfortunately I have little relevant information. So if anyone can help me with finding relevant links to good online tutorials or howto's than those are very welcome.

• Is there a way to make XmlDocument parsing less strict

  - by Istrebitel

  I am making a program that will store its data in an XML file. When people write XML they can make subtle mistakes, like ending a comment with - so it looks like <!-- comment ---> or adding a </>inside an attribute. Naturally, the XML still can be read all right, but trying to input this text into XmlDocument will give a syntax error (and it wont be parsed). Is there a way to make XmlDocument less strict and make it ignore violations of the standard that do not make the document unparseable? For example, its clear that <!-- comment ---> is still a comment even though it contains - at the end which is against the standard specification).

• .htaccess stupid issue

  - by justnoone

  I have a server where I can only configure httpd using .htaccess, a cannot access global configuration. I want to rewrite almost every non-existing path to index.php, so I did something like: RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?path=$1 [L,QSA] And that is ok. But another thing I want to do is to prevent access to path where I keep PHP files (I cannot store them somewhere else) which is for example /php. I would like that anything starting with /php rewrites to index.php?path=php... so I did something like: RewriteCond %{REQUEST_URI} ^/php.* RewriteRule ^(.*)$ /index.php?path=$1 [L,QSA] And that also would work ok if I had access to global configuration. In case of per-directory configuration, when I access /php it rewrites it to index.php?path=php and than puts directory name before that: /php/index.php?path=php. I read documentation and I realize that it uses internal redirects when per-directory confoguration is used. How can I avoid this behavior?

• facebook extended access token login

  - by Pota Onasys

  I have the following code: $facebook = new Facebook(array( 'appId' => ID, 'secret' => SECRET, 'cookie' => true)); $fb_uid = $facebook->getUser(); if($fb_uid) { // check if person with fb_uid as facebook id in database, // if so log them in. If not, register them. $fb_user = $facebook->api('/' . $fb_uid); I then get their email address using $fb_user['email'] and facebook_id and store in the database as a means to log them in the future Sometimes $fb_uid returns false even though the person is logged in using facebook ... I think it is because the access token expires. how can I change this code to incorporate the extended access token to log in the user to my site? offline access token is deprecated, so I need to use the extended access token.

• Storing HTML in MySQL using Java

  - by mpcabd

  Hello there again, So, I'm working on a project now where I should store webpages inside a database, I'm using crawler4j to crawl and Proxool along with MySQL Java Connector to connect to my database. When I tested the application I got: com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data too long for column 'HTMLData'. The HTMLData column wasTEXT. When I changed the HTMLData column to LONGTEXT the error was gone, but I'm afraid it might get back in the future. Any idea on how to do that perfectly so I don't worry about that error (or any other similar error) in the future? Thanks :)

• small string optimization for vector?

  - by BuschnicK

  I know several (all?) STL implementations implement a "small string" optimization where instead of storing the usual 3 pointers for begin, end and capacity a string will store the actual character data in the memory used for the pointers if sizeof(characters) <= sizeof(pointers). I am in a situation where I have lots of small vectors with an element size <= sizeof(pointer). I cannot use fixed size arrays, since the vectors need to be able to resize dynamically and may potentially grow quite large. However, the median (not mean) size of the vectors will only be 4-12 bytes. So a "small string" optimization adapted to vectors would be quite useful to me. Does such a thing exist? I'm thinking about rolling my own by simply brute force converting a vector to a string, i.e. providing a vector interface to a string. Good idea?

• magento override sort order of product list by subcategories

  - by dardub

  I'm setting up a new store using 1.4.1 I'm trying sort the products in the list by the subcategories they belong to. At the top of list.phtml is $_productCollection=$this->getLoadedProductCollection(); I tried adding sort filters to that by adding the line $_productCollection->setOrder('category_ids', 'asc')->setOrder('name', 'asc'); I also tried addAttributeToSort instead of setOrder. This doesn't seem to have any effect. I'm guessing that $_productCollection is not a model I can sort in this manner. I have been digging around trying to find the correct place to apply the sort method without any success. Can someone tell me the proper place to do this?
