• Magento "File was not uploaded"

  - by John

  I'm currently using the magento admin interface, trying to upload an image in the "manage products" and I get the error "file was not uploaded" after I browse the file and click "upload file". I've looked on other forums and the main solution I saw were to make sure that php.ini has the following lines... magic_quotes_gpc = off short_open_tag = on extension=pdo.so extension=pdo_mysql.so I have Windows/IIS with ISAPI_Rewrite. Is there a max file upload size that I can change somewhere. I'm uploading pictures from my local desktop of size ~100kb. help!

• Avoid stuck calling callback

  - by andlomba

  Hello all, This is a question about generic c++ event driven applications design. Lets assume that we have two threads, a "Dispatcher" (or "Engine"...) and a "Listener" (or "Client"...). Let's assume that I write the Dispatcher code, and release it as a library. I also write the Listener interface, of course. When the Dispatcher executes (after Listener registration) listenerInstance.onSomeEvent(); the event handling code will actually be executed by the Dispatcher thread, so if the person that implements the Listener writes something like void Listener::onSomeEvent() { while(true) ; } The Dispatcher will stuck forever. Is there a "plain old c++" (I mean no boost or libsigc++) way to "decouple" the two classes, so I can be sure that my Dispatcher will work fine whatever the Listeners does in the callbacks? bye and thanks in advance, Andrea

• How to create custom CSS "on the fly" based on account settings in a Django site?

  - by sdolan

  So I'm writing a Django based website that allows users select a color scheme through an administration interface. I already have middleware/context processors that links the current request (based on domain) to the account. My question is how to dynamically serve the CSS with the account's custom color scheme. I see two options: Add a CSS block to the base template that overrides the styles w/variables passed in through a context processors. Use a custom URL (e.g. "/static/dynamic/css//styles.css") that gets routed to a view that grabs all the necessary values and creates the css file. I'm content with either option, but was wondering if anyone else out there has dealt with similar problems and could give some insight as to "Best Practices".

• Android browser javascript events when minimised

  - by Sirber

  I'm building a webapp for Android smartphones that runs with the OS internet browser. the main interface is to input datas. the data is added to a queue (android 1.5: gears, android 2.x: html5). Each 5 minutes (using setTimeout), the script looks if an internet connection is active, and if so, sends all the queue to the server. If the phone is plugged on the wall and the webpage is ontop, the timeout works. if the browser is minimized or another application runs on top of it, the timeout doesn't work. if the phone is in sleep mode it doesn't work either. can only native apps runs in background?

• frame variable cannot be found

  - by Umzz Mo

  I am making 3 board games, and I have started my coding off in one class. Now that i wanted to move around it is giving me problems. In my view class I just want to have the main frame where users can pick from the games. And in the other views, i.e the childrens of view class i want to have the interface for the actual games. Now that the Jframe frame = new frame was created in the parent class, it cannot find the variable frame in the children classes.

• Passing object through WCF so that server receives client changes

  - by cvig

  I would like to set up a WCF service so that any changes a client makes to an object I send them are also reflected on the server side. For example, if Assembly A has the following... namespace AssemblyA { public class Person { public string FirstName { get; set; } public string LastName { get; set; } } [ServiceContract] public interface IServer { [OperationContract] Person GetPerson(); } } And Assembly B references Assembly A... using AssemblyA; namespace AssemblyB { class Program { static void Main(string[] args) { <snip> IServer server = factory.CreateChannel(); Person person = server.GetPerson(); person.FirstName = "Kilroy"; person.LastName = "WuzHere"; } } } What is the easiest/best way to make it so that the service's copy of the Person object also reflects the changes that the client makes? Is this even possible?

• How to temporarily change all default user settings without destroying the original?

  - by mystify

  My app is based strongly on a lot of NSUserDefault keys and values. I want to implement a temporary defaults profile which the user can activate to get a special task done easily. For this, some of the user defaults must be changed temporarily so the app adjusts it's interface appropriately. I started to just manually change those NSUserDefaults settings, but this also destroys the user's original settings. Is it possible to keep a backup of the user's NSUserDefault settings and restore them after the user quits the temporary mode or the app? Like I see it, NSUserDefaults actually is just an NSMutableDictionary which is generated out of a plist file. So I would just make a deep copy of that and later assign that copy somehow back to NSUserDefaults?

• Passing a NSString to another ViewController using classes

  - by Jeff Kranenburg

  I know this insanely simple, but I am re-teaching myself the basics and trying to get my head around this:-) I have one ViewController called MainVC and I have one called ClassVC In ClassVC I have this code: @interface ClassVC : UIViewController { NSString *mainLine; } @property (nonatomic, retain) NSString *mainLine; @end and I have this in the implementation file: @synthesize mainLine = _mainLine; -(NSString *)_mainLine { _mainLine = @"This a string from a Class"; return _mainLine; } Now I was thinking that if I #import the ClassVC into MainVC I would be able to transfer that string along as well like so: This code is in the viewDidLoad _mainLabel.text = _secondClass.mainLine; NSLog(@"%@", _secondClass.mainLine); But that is not working - so cannot I not pass strings in through this way???

• List show/add/remove View

  - by Michael

  Looking for some best practices of UI list on iPhone which has item add/modify/delete functions. Please refer to some sample codes or articles to build user friendly interface. The main application is tab bar application and one of the tabs supposed to show item management. The item itself consisting of 3 text items, first one can be label, it's short, the rest if it's not terribly complicated I would like to show below with small font or show when user taps on item entering edit mode... Not sure how to design all this and which views to use.

• Advice on creating simple web service

  - by London

  Hi all, I want to build simple SOAP web service. So far I've only worked with existing SOAP/Rest services. And now I'd like to create my own, simple one for starters. For example create simple hello + string web service where I provide the string in request from SOAP ui or similar tool. I have Jboss server installed already, what is the "simplest" possible way to achieve this? I realize I need interface, interfaceImpl, and a wsdl file(generated possibly). Does anyone have some useful advice for me ? thank you

• Should I combine unrelated interfaces into a single library?

  - by mafutrct

  Situation is like this: There are independent 5 services. Each service consists of a project for interface, implementation and test. Example: LocalizationService.Interfaces LocalizationService.Implementation LocalizationService.Test There is a WCF service for each of the services: LocalizationService.WcfContract (including DataContracts) LocalizationService.WcfHost The client applications are probably mostly going to use all of the services. Should I combine all service interfaces into a common one? AllServices.AllInterfaces In my opinion, this is a bad idea. The services are independent and there is no reason to introduce a dependency. I imagine that especially testing becomes more difficult. However, one may argue that having to include 5 libraries is too much of a hassle. (I'm not sure how to tag this. Feel free to retag.)

• Do programmable Ethernet devices (think onboard CPU) really exist?

  - by PeterM

  I've heard from various people that programmable Ethernet cards exist and are easily available. However I have yet to be able to track down one of these mythical devices so I'm wondering if they're just that - a myth. Such a programmable card has a gigabit Ethernet interface, has a programmable CPU and connects to the host system via PCI Express. The problem area these cards address are low latency network applications where the card itself does the work and "reports back" to the operating system. Basically the card acts as a co-processor and handles all the low latency requirements on the card, thus avoiding the issues of writing low latency code in user-land - think 0.4ms - 0.5ms response times. So my question is, do these cards really exist and if so, where can I get my hands on one?

• What the best way to convert from String to HashMap?

  - by eugenn

  I would like to serialize a Java HashMap to string representation. The HashMap will contains only primitive values like string and integer. After that this string will be stored to db. How to restore back the HashMap? Is it make sense to use BeanUtils and interface Converter or use JSON? For example: List list = new ArrayList(); list.add(new Long(1)); list.add(new Long(2)); list.add(new Long(4)); Map map = new HashMap(); map.put("cityId", new Integer(1)); map.put("name", "test"); map.put("float", new Float(-3.2)); map.put("ids", list); map.toString() -> {float=-3.2,ids=[1, 2, 4],name=test,cityId=1} map.toJSON -> {"float":-3.2,"ids":[1,2,4],"name":"test","cityId":1}

• Qt: QAbstractItemModel and 'const'

  - by Eye of Hell

  Hello. I'm trying to use a QTreeView for a first time, with a QAbstractItemModel. And instantly it's a problem: QAbstractItemModel interface declares methods as 'const', assuming they will not change data. But i want a result of SQL query displayed, and returning data for a record with specified indeq REQUIRES to use QSqlQuery::seek() that is a non-const. Is it any 'official' guideline to use a QAbstractItemModel with data that MUST be changed in order to get number of items, data per item etc? Or i must hack C++ with const casts?

• How can we make the video play in a small view and also filling that whole view?

  - by wolverine

  I have added an imageView of size 300*300 into the interface in my ipad project. I can play the video fullscreen using MPMOviePlayerController. And I am trying to make it play in the imageView by using the following code. [imageView1 addSubview:moviePlayer.view]; [self.moviePlayer play]; Its playing but not as fullscreen and also not filling the whole imageview. Its kind of playing on the top quarter of the view and that too not the whole movie view - about lower right 60% only. How can I fix this? How can I make the movie play on the whole imageview like it plays on the full screen?

• What exactly does a self-describing type in .Net mean?

  - by tzup

  Given this MSDN article, we learn that the Common Type System in .Net has this classification of reference types: "Reference types can be self-describing types, pointer types, or interface types. The type of a reference type can be determined from values of self-describing types. Self-describing types are further split into arrays and class types." So an array, for instance, is a self-describing type because we can determine it's type from its values? How? Is that it, or is there more to this definition?

• Is there a way to set the value of $? in a mock in Ruby?

  - by rleber

  I am testing some scripts that interface with system commands. Their logic depends on the return code of the system commands, i.e. the value of $?. So, as a simplified example, the script might say: def foo(command) output=`#{command}` if $?==0 'succeeded' else 'failed' end end In order to be able to test these methods properly, I would like to be able to stub out the Kernel backquote call, and set $? to an arbitrary value, to see if I get appropriate behavior from the logic in the method after the backquote call. I can't figure out a way to do this. (In case it matters, I'm testing using Test::Unit and Mocha.)

• How do I create email addresses for all my users using my domain ([email protected])?

  - by rwain

  My client wants to create email addresses for all their dotnetnuke users using their domain. The point is to keep the user's email addresses 'private' while still allowing communication through a public email address that they can control. It's not necessary to have a full webmail interface (although that would be nice). I'm thinking it would be enough just to forward any mail on and just act as a gateway. So if an email was sent to [email protected], it would be forwarded on to the email address associated with the dotnetnuke account with username 'rwain'. Is this possible to do in a shared hosting environment? Or do I need to create some custom mail server that does a conversion of the email address and forwards it?

• Purely functional equivalent of weakhashmap?

  - by Jon Harrop

  Weak hash tables like Java's weak hash map use weak references to track the collection of unreachable keys by the garbage collector and remove bindings with that key from the collection. Weak hash tables are typically used to implement indirections from one vertex or edge in a graph to another because they allow the garbage collector to collect unreachable portions of the graph. Is there a purely functional equivalent of this data structure? If not, how might one be created? This seems like an interesting challenge. The internal implementation cannot be pure because it must collect (i.e. mutate) the data structure in order to remove unreachable parts but I believe it could present a pure interface to the user, who could never observe the impurities because they only affect portions of the data structure that the user can, by definition, no longer reach.

• How to remove thie ".svc" extension in RESTful WCF service?

  - by Morgan Cheng

  In my knowledge, the RESTful WCF still has ".svc" in its URL. For example, if the service interface is like [OperationContract] [WebGet(UriTemplate = "/Value/{value}")] string GetDataStr(string value); The access URI is like "http://machinename/Service.svc/Value/2". In my understanding, part of REST advantage is that it can hide the implementation details. A RESTful URI like "http://machinename/Service/value/2" can be implemented by any RESTful framework, but a "http://machinename/Service.svc/value/2" exposes its implementation is WCF. How can I remove this ".svc" host in the access URI?

• backgroundworkers or threadpools

  - by vbNewbie

  I am trying to create an app that allows multiple search requests to occur whilst maintaining use of the user interface to allow interaction. For the multiple search requests, I initially only had one search request running with user interaction still capable by using a backgroundworker to do this. Now I need to extend these functions by allowing more search functions and basically just queueing them up. I am not sure whether to use multiple backgroundworkers or use the threadpool since I want to be able to know the progress of each search job at any time.

• Is there a reference document for OOTB SharePoint web part interfaces?

  - by Javaman59

  I want my web parts to act as providers and consumers with OOTB SharePoint web parts, including filters. To design these web parts I need to know the interface of the OOTB web parts, eg. a "Links" web part provides an IWebPartRow, with a Type, URL and Notes. I can get the information by: a web part programmed to interact generically, and display the data it receives putting the web parts on a page, and look at the available connections inspecting the DLL's (haven't tried this, because I can't find the DLL's, but I guess it's possible) It seems strange to me that there is no documentation of these interfaces. Is there a Microsoft document, or a book, which documents the OOTB web parts and filters?

• How do I create a create and execute an SQL command using OleDB directly?

  - by Pagis

  I want to use the OleDB interfaces directly to open a connection to a DB, create a command and executing it (for example using the ICommandText interface). The main thing I can't find is how to create the connection and the command object and how to connect the object that implements the ICommandText to the connection. In ADO I would just use the ActiveConnection property but I want to do this directly on the OleDB interfaces. Also, if anyone can recommend a tutorial to OleDB, ether online or a book, free or not that would be great (but a tutorial and not just a reference / API) I'm using C++ but any native code would be fine.
