• Using iterateFunc to call objective c method

  - by Matt Welch

  Using spacemanager, I need to perform an action on select bodies after each step, so I figured that defining my own C function for iterateFunc would be the way to go. Everything works great, except I'm not sure how to then call an obj c method in the same class. In other words, an obj c class contains both the c function replacing iterateFunc, and the method that needs to be called. I don't see how to tell the c function what 'self' is, such that I can call the method. As far as i can tell, there's no way to pass in any extra info to the new iterateFunc. Any ideas, or a better way to go about things?

• How to avoid piracy in iPhone apps by server side validation?

  - by prathumca

  As par my app requirement, there is a couple of scenarios that I need to handle. Scenario 1: To avoid piracy, I want to include some piece of code, whose job is sending both IMEI and Serial number of IPhone. Scenario 2: At server side, I've a database, which has a list of both IMEI and Serial No info. Here I wanna validate both IMEI and Serial numbers. If both are not matched then I can make sure that the app is pirated. Idea seems good. But I don't know how to handle these two scenarios in my app. Any help is greatly appreciated.

• iPhone CALayer Stacking Order

  - by Brian

  I'm using CALayers to draw to a UITableViewCell. I'm trying to figure out how layers are ordered with the content of the UITableViewCell. For instance: I add labels to the UITableViewCell in my cellForRow:atIndexPath method In the drawRect method of UITableViewCell I draw some content using the current context Also, in drawRect I add a few sublayers So what would be the order of these elements. I know I have zPosition on the CALayers but I'm not sure if they are always on top of any subviews of the UITableViewCell. And I'm not sure where the content that is drawn in drawRect comes in the order. Any help or links to documentation would be great. I have read through the Core Animation Programming Guide and didn't see anywhere where this would be answered.

• Differences between query using LINQ and IQueryable interface directly?

  - by JohnMetta

  Using Entity Framework 4, and given: ObjectSet<Thing> AllThings = Context.CreateObjectSet<Thing>; public IQueryable<Thing> ByNameA(String name) { IQueryable<Thing> query = from o in AllThings where o.Name == name select o; return query; } public IQueryable<Thing> ByNameB(String name) { return AllThings.Where((o) => o.Name == name); } Both return IQueryable< instances, and thus the query doesn't hit the server until something like ToList() is called, right? Is it purely readability that is the difference, or are the using fundamentally different technologies on the back-end?

• Stripes link event triggering validation that is incorrect.

  - by Davoink

  I have stripes:link tag in a jsp with an event attribute: <stripes:link href="${actionBean.context.currentStage.stripesForwardAction}" addSourcePage="true" event="showTab2Link"> This triggers the validation to trigger on nested properties: @ValidateNestedProperties({ @Validate(field="county", required=true, minlength=2, maxlength=2, mask="\\d\\d"), @Validate(field="parish", required=true, minlength=3, maxlength=3, mask="\\d\\d\\d"), @Validate(field="holding", required=true, minlength=4, maxlength=4, mask="\\d\\d\\d\\d") }) However this would been fine if the actual values it is validation are not present, but they are present within the html and when debugging the bean. Why would the stripes:link trigger this? If I change it to an stripes:submit then it is fine. thanks, Dave

• Ruby on Rails: attr_accessor for submodels

  - by williamjones

  I'm working with some models where a lot of a given model's key attributes are actually stored in a submodel. Example: class WikiArticle has_many :revisions has_one :current_revision, :class_name => "Revision", :order => "created_at DESC" end class Revision has_one :wiki_article end The Revision class has a ton of database fields, and the WikiArticle has very few. However, I often have to access a Revision's fields from the context of a WikiArticle. The most important case of this is probably on creating an article. I've been doing that with lots of methods that look like this, one for each field: def description if @description @description elsif current_revision current_revision.description else "" end end def description=(string) @description = string end And then on my save, I save @description into a new revision. This whole thing reminds me a lot of attr_accessor, only it doesn't seem like I can get attr_accessor to do what I need. How can I define an attr_submodel_accessor such that I could just give field names and have it automatically create all those methods the way attr_accessor does?

• How to create a controllable flip effect (flip as far (and fast) as you drag) of an UIView

  - by allisone

  I have a card (a flashcard you could say) What I can do: On fingersweeping over the flashcard the card gets turned. It's happening by detecting touchesBegan and touchesMoved and then I do stuff like [UIView beginAnimations:@"View Flip" context:nil]; [UIView setAnimationDuration:0.5]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; if (left) { [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:self.flashCardView cache:YES]; }else{ [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:self.flashCardView cache:YES]; } What I can't do (but want to): I want to somehow drag the flip. Imagine this, you have a flashcard and you think you know the answer, you start flipping the card around because you want to see if you are correct, but then... no stop... you hesitate, turn back the card to the way it was, rethink, get the real answer and then finally flip to see that you were right to hesitate. Now I only have: once you start flipping, you can't stop it.

• Metadata requirements for developers

  - by Paul James

  I'm tasked with providing a list of metadata requirements our data warehouse developers might need. This is not the business metadata (nice descriptions etc), but rather data required for change management (also known as impact assesment), data lineage etc. I've seen this article Meta Meta Data Data - Ralph Kimball but as I'm not the first person to do this I'm throwing it to the SO community. The actual question is this: What metadata do datawarehouse developers require to design, develop and manage change in ETL routines? PS: I'm trying to keep the answer platform agnostic but for context this is an Oracle database with PL/SQL and Datastage.

• IIS 6 session timing out a lot quicker than expected

  - by Echiban

  I am working with an web application that has its sessions timing out a lot quicker than expected. We expected a timeout of 15 minutes but it's timing out at 3-4 minutes. Info about environment: IIS6 classic ASP / COM+ app timeout OK on current PROD, much quicker in dev / QA environments We already disabled app pool recycling, and even put IIS in isolation mode - no effect HTTP err log doesn't display any lines when session times out We've done a close comparison of PROD and DEV / QA environments, and given we use virtual machines on all of them, settings should be preserved. I tried to find IIS blog notes from David Wang but many of them now have HTTP 404 errors, and I don't know what else to do. Please help! At the very least, is there a way to get IIS to log every time a session expires? At the very least some means of logging / debugging IIS would be useful. Thanks in advance.

• How to use SMS content provider? Where are the docs?

  - by Mark

  Hi, I'd like to be able to read the system's SMS content provider. Basically I wanted to make an SMS messaging app, but it would only be useful if I could see past threads etc. It seems like there's a content provider for this, but I can't find documentation for it - anyone know where that is? Thanks -------- edit ----------- Ok I found a way to get the sms inbox provider, and I just dumped all the column names in that provider, looks like this: Uri uriSms = Uri.parse("content://sms/inbox"); Cursor c = context.getContentResolver().query(uriSms, null,null,null,null); // column names for above provider: 0: _id 1: thread_id 2: address 3: person 4: date 5: protocol 6: read 7: status 8: type 9: reply_path_present 10: subject 11: body 12: service_center 13: locked I'm just piecing this together from random threads I find around the net, I'm really wondering where this is all documented (if at all)? Thanks again

• Chrome Extension contenteditable get and set caret position

  - by jwize

  I am creating an extension where I need to insert a link into the gmail window. I am able to create a simple extension button in the top of the window and execute code that does replaces all the links. Now, I want to do add links in the contenteditable section as I type. It seems like there should be a simple way to replace text with a link in the document object model. If this is not true I need to do three things. Insert text from the current caret position Capture the caret position. Set the caret position by its offset. I have tried using window.getSelection within the gmail context(that is a body element that is set to contenteditable and embedded inside an iframe in the gmail tab) to get the current range and position. The selection is always empty and contains no ranges regardless of whether text is selected or not.

• Stream post URL security and wall post links

  - by Jeff Lee

  Our app's mobile client can create wall post links to our app's web-facing pages. Since this happens in the context of a mobile app, we do this on behalf of our user using the Graph API's feed/message endpoint. I noticed that the links showing up in the wall posts are being routed through our app's auth dialog, which is NOT what we want. We just want transparent links, without forcing the client to auth our app, similar to what happens when you share to FB in Path. I went ahead and disabled the "Stream post URL option" several hours ago, but we still seem to be getting the re-routed links for wall posts. The target URLs for these links are within the domain we've registered for our Facebook app. Is there anything else I need to do fix this?

• PHP & MySQLi timeout

  - by Dt7

  Whenever I try to create a mysqli object, as in; $mysqli = new mysqli(host, user, pass, table); ...the page just loads for around a minute, then stops, showing all the content of the page up until that line. info() says that MySQLi (and MySQL if that matters) are enabled, and I can access the MySQL CLI. I'm also working on a local machine, not a remote server. I feel like I've missed something obvious. Can anyone shed some light on it? Edit: just for clarification, I am actually putting real values into the mysqli constructor :)

• Exception handling in Boost.Asio

  - by Alex B

  Boost.Asio documentation suggests the following exception handling pattern: boost::asio::io_service io_service; ... for (;;) { try { io_service.run(); break; // run() exited normally } catch (my_exception& e) { // Deal with exception as appropriate. } } The problem with it is that the context of exception is lost at the point when it's handled. For example, if I have multiple socket sessions going on, I don't know which one caused the exception to be thrown. What would be a better way to handle the exceptions from asynchronous handlers without wrapping them in try/catch blocks?

• My site not directing links correctly.

  I have a site at http://badassmonkeys.com/ and when i click any of the links it does not direct it to the actual page but still pulls up the link. For some reason it works perfectly on linux cpanel and actually loads the pages, but on windows in apache, or in IIS even with a rewrite mod for it, it just doesnt work. The links dont go correctly.

• Connecting Java se Client to Glassfish

  - by Henrik Bierbum Bacher

  We are having some difficulties connecting our Java SE standalone client with the EJB module deployed on a remote GlassFish server. Pointers to how we are supposed to connect our client would be appreciated. The client code we currently has to get the initial context: props.setProperty("org.omg.CORBA.ORBInitialHost", "*remotehost*"); props.setProperty("org.omg.CORBA.ORBInitialPort", "portNumber"); javax.naming.InitialContext ic = new javax.naming.InitialContext(props); *We have tried several different port numbers; 3700, 7676, 8080.. The closest we are getting, got us the error: "Error in GIOP magic". I read that jms are using port 7676 as a broker port for a bunch of dynamically generated ports, but can't figure out how to specify those ports in order to create proper port-forwards.

• Caching issues with TDBadgedCell

  - by Wolfgang Schreurs

  This post is closely related to my previous post: http://stackoverflow.com/questions/2201256/tdbadgedcell-keeps-caching-the-badgenumber The "badge" from TDBadgedCell keeps caching the numbers. A very simple example is shown here: - (UITableViewCell *)tableView:(UITableView *)_tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; TDBadgedCell *cell = (TDBadgedCell *)[_tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[TDBadgedCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier]; [cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator]; } [cell setBadgeColor:[UIColor blackColor]]; [cell setBadgeNumber:[indexPath row]]; [[cell textLabel] setText:[NSString stringWithFormat:%@"%d", [indexPath row]]]; return cell; } Anyone has any clue why this happens? The textLabel and detailTextLabel don't cache the data. Any additonal info would be welcome as well, as I seem to have a lot of issues with the caching of graphics in UITableViewCells. Any best practices or other useful information would be most welcome.

• How to assert/unit-test servers JSON response?

  - by shazax

  My current project uses JSON as data interchange format. Both Front-end and Back-end team agree upon a JSON structure before start integrating a service. At times due to un-notified changes in JSON structure by back-end team; it breaks the front-end code. Is there any external library that we could use to compare a mock JSON (fixture) with servers JSON response. Basically it should assert the whole JSON object and should throw an error if there is any violation in servers JSON format. Additional info: App is built on JQuery consuming REST JSON services.

• RST packet sent by the server

  - by intoTHEwild

  I am developing a client in Flash and using http req/resp to communicate with the server. For a while the session works fine and then the connection is terminated by the server. I did a wireshark sniff at the server and the last message which it sends is a RST packet. Also it happens only when I'm using IE and the server and client are in different domains. This does not happen in FireFox. I have been struggling to find a sol, till I found this thread. It's a bit old but I hope I could get some help. I am not sure if this bit of info is important but I am connecting to the server via a gateway. Any clue or suggestions for where should I look into to locate the problem ?
