• Does height and width not apply to span?

  - by Kyle Sevenoaks

  Total noob question, but here. CSS .product__specfield_8_arrow { /*background-image:url(../../upload/orng_bg_arrow.png); background-repeat:no-repeat;*/ background-color:#fc0; width:50px !important; height:33px !important; border: 1px solid #dddddd; border-left:none; border-radius:5px; -moz-border-radius:5px; -webkit-border-radius:5px; border-bottom-left-radius:0px; border-top-left-radius:0px; -moz-border-radius-bottomleft:0px; -moz-border-radius-topleft:0px; -webkit-border-bottom-left-radius:0px; -webkit-border-top-left-radius:0px; margin:0; padding:2px; cursor:pointer; }??? HTML <span class="product__specfield_8_arrow">&nbsp;</span>? Fiddle Basically I'm trying to emulate a button, make a span (or something) look like a button next to an input field that actually doesn't need to be one because of an auto fill generator that generates errors onEnter. Thought this'd be a quick fix for now but obviously not. Thanks.

• Core data setReturnsDistinctResult not working

  - by Moze

  So i'm building a small application, it uses core data database of ~25mb size with 4 entities. It's for bus timetables. In one table named "Stop" there are have ~1300 entries of bus stops with atributes "name", "id", "longitude", "latitude" and couple relationships. Now there are many stops with same name but different coordinates and id. Search is implemented using NSPredicate. So I want to show all distinct stop names in table view, i'm using setReturnsDistinctResults with NSDictionaryResultType and setPropertiesToFetch. But setReturnsDistinctResult is not working and I'm still getting all entries. Heres code: - (NSFetchRequest *)fetchRequest { if (fetchRequest == nil) { fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Stop" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSArray *sortDescriptors = [NSArray arrayWithObject:[[[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES] autorelease]]; [fetchRequest setSortDescriptors:sortDescriptors]; [fetchRequest setResultType:NSDictionaryResultType]; [fetchRequest setPropertiesToFetch:[NSArray arrayWithObject:[[entity propertiesByName] objectForKey:@"name"]]]; [fetchRequest setReturnsDistinctResults:YES]; DebugLog(@"fetchRequest initialized"); } return fetchRequest; } ///////////////////// - (NSFetchedResultsController *)fetchedResultsController { if (self.predicateString != nil) { self.predicate = [NSPredicate predicateWithFormat:@"name CONTAINS[cd] %@", self.predicateString]; [self.fetchRequest setPredicate:predicate]; } else { self.predicate = nil; [self.fetchRequest setPredicate:predicate]; } fetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:self.fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:sectionNameKeyPath cacheName:nil]; return fetchedResultsController; } ////////////// - (UITableViewCell *)tableView:(UITableView *)table cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = [[fetchedResultsController objectAtIndexPath:indexPath] valueForKey:@"name"]; return cell; }

• Unexpected performance curve from CPython merge sort

  - by vkazanov

  I have implemented a naive merge sorting algorithm in Python. Algorithm and test code is below: import time import random import matplotlib.pyplot as plt import math from collections import deque def sort(unsorted): if len(unsorted) <= 1: return unsorted to_merge = deque(deque([elem]) for elem in unsorted) while len(to_merge) > 1: left = to_merge.popleft() right = to_merge.popleft() to_merge.append(merge(left, right)) return to_merge.pop() def merge(left, right): result = deque() while left or right: if left and right: elem = left.popleft() if left[0] > right[0] else right.popleft() elif not left and right: elem = right.popleft() elif not right and left: elem = left.popleft() result.append(elem) return result LOOP_COUNT = 100 START_N = 1 END_N = 1000 def test(fun, test_data): start = time.clock() for _ in xrange(LOOP_COUNT): fun(test_data) return time.clock() - start def run_test(): timings, elem_nums = [], [] test_data = random.sample(xrange(100000), END_N) for i in xrange(START_N, END_N): loop_test_data = test_data[:i] elapsed = test(sort, loop_test_data) timings.append(elapsed) elem_nums.append(len(loop_test_data)) print "%f s --- %d elems" % (elapsed, len(loop_test_data)) plt.plot(elem_nums, timings) plt.show() run_test() As much as I can see everything is OK and I should get a nice N*logN curve as a result. But the picture differs a bit: Things I've tried to investigate the issue: PyPy. The curve is ok. Disabled the GC using the gc module. Wrong guess. Debug output showed that it doesn't even run until the end of the test. Memory profiling using meliae - nothing special or suspicious. ` I had another implementation (a recursive one using the same merge function), it acts the similar way. The more full test cycles I create - the more "jumps" there are in the curve. So how can this behaviour be explained and - hopefully - fixed? UPD: changed lists to collections.deque UPD2: added the full test code UPD3: I use Python 2.7.1 on a Ubuntu 11.04 OS, using a quad-core 2Hz notebook. I tried to turn of most of all other processes: the number of spikes went down but at least one of them was still there.

• Rolling Back a Transaction with MySQL Connector in VB.net

  - by Jonathan

  Hey all- I have one multi-row INSERT statement (300 or so sets of values) that I would like to commit to the MySQL database in an all-or-nothing fashion. insert into table VALUES (1, 2, 3), (4, 5, 6), (7, 8, 9); In some cases, a set of values in the command will not meet the criteria of the table (duplicate key, for example). When that happens I do not want any of the previous sets added to the database. I've implemented this with the following code, however, my rollback command doesn't appear to be making a difference. I've used this documentation: http://dev.mysql.com/doc/refman/5.0/es/connector-net-examples-mysqltransaction.html Dim transaction As MySqlTransaction = sqlConnection.BeginTransaction() sqlCommand = New MySqlCommand(insertStr, sqlConnection, transaction) Try sqlCommand.ExecuteNonQuery() Catch ex As Exception writeToLog("EXCEPTION: " & ex.Message & vbNewLine) writeToLog("Could not execute " & sqlCmd & vbNewLine) Try transaction.Rollback() writeToLog("All statements were rolled back." & vbNewLine) Return False Catch rollbackEx As Exception writeToLog("EXCEPTION: " & rollbackEx.Message & vbNewLine) writeToLog("All statements were not rolled back." & vbNewLine) Return False End Try End Try transaction.commit() I get the DUPLICATE KEY exception thrown, no Rollback Exception thrown, and every set of values up to duplicate key committed to the database. What am I doing wrong? Thanks- Jonathan

• CSS: Horizontal scrolling with overflow-x

  - by ams

  Hello fellow programmers, I was wondering if there still isn't a good way to get a div to stretch and scroll horizontally, according to the images inside. -After all, it is 2011 now! The mega-width does the trick, but leaves an empty mega-space if not filled with images. If filled too much, images don't display. Same for the jQuery. The situation below is the best I can do after hours of Googling, but it isn't reliable enough. Thanks for your time. Ams * { margin:0; padding:0; } #one { width:200px; height:250px; overflow-x:auto; overflow-y:hidden; } #two { width:10000em; } #two img { float:left; } $(document).ready(function(){ var total=0; $(".calc").each(function(){ total += $(this).outerWidth(true); }); $("#two").css('width',total); alert(total); }); <div id="one"> <div id="two"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> <img src="images/testimage3.jpg" width="480" height="192" class="calc"> </div> </div>

• Invalid argument in sendfile() with two regular files

  - by Daniel Hershcovich

  I'm trying to test the sendfile() system call under Linux 2.6.32 to zero-copy data between two regular files. As far as I understand, it should work: ever since 2.6.22, sendfile() has been implemented using splice(), and both the input file and the output file can be either regular files or sockets. The following is the content of sendfile_test.c: #include <sys/sendfile.h> #include <fcntl.h> #include <stdio.h> int main(int argc, char **argv) { int result; int in_file; int out_file; in_file = open(argv[1], O_RDONLY); out_file = open(argv[2], O_WRONLY | O_CREAT | O_TRUNC, 0644); result = sendfile(out_file, in_file, NULL, 1); if (result == -1) perror("sendfile"); close(in_file); close(out_file); return 0; } And when I'm running the following commands: $ gcc sendfile_test.c $ ./a.out infile The output is sendfile: Bad file descriptor Which means that the system call resulted in errno = -EINVAL, I think. What am I doing wrong?

• How to reliably replace a library-defined error handler with my own?

  - by sharptooth

  On certain error cases ATL invokes AtlThrow() which is implemented as ATL::AtlThrowImpl() which in turn throws CAtlException. The latter is not very good - CAtlException is not even derived from std::exception and also we use our own exceptions hierarchy and now we will have to catch CAtlException separately here and there which is lots of extra code and error-prone. Looks like it is possible to replace ATL::AtlThrowImpl() with my own handler - define _ATL_CUSTOM_THROW and define AtlThrow() to be the custom handler before including atlbase.h - and ATL will call the custom handler. Not so easy. Some of ATL code is not in sources - it comes compiled as a library - either static or dynamic. We use the static - atls.lib. And... it is compiled in such way that it has ATL::ThrowImpl() inside and some code calling it. I used a static analysis tool - it clearly shows that there're paths on which the old default handler is called. To ensure I even tried to "reimplement" ATL::AtlThrowImpl() in my code. Now the linker says it sees two declarations of ATL::AtlThrowImpl() which I suppose confirms that there's another implementation that can be called by some code. How can I handle this? How do I replace the default handler completely and ensure that the default handler is never called?

• JMX - MBean automated registration on application deployment

  - by Gadi

  Hi All, I need some direction with JMX and J2EE. I am aware (after few weeks of research) that the JMX specification is missing as far as deployment is concerned. There are few vendor specific implementations for what I am looking for but none are cross vendor. I would like to automate the deployment of MBeans and registration with the Server. I need the server to load and register my MBeand when the application is deployed and remove when the application is un-deployed. I develop with: NetBean 6.7.1, GlassFish 2.1, J2EE5, EJB3 More specific, I need a way to manage timer service runs. My application need to run different archiving agents and batch reporting. I was hoping the JMX will give me remote access to create and manage the timer services and enable the user to create his own schedule. If the JMX is auto registered on application deployment the user can immediately connect and manage the schedule. On the other hand, how can an EJB connect/access an MBean? Many thanks in advance. Gadi.

• Entity Framework 4 / POCO - Where to start?

  - by Basiclife

  Hi, I've been programming for a while and have used LINQ-To-SQL and LINQ-To-Entities before (although when using entities it has been on a Entity/Table 1-1 relationship - ie not much different than L2SQL) I've been doing a lot of reading about Inversion of Control, Unit of Work, POCO and repository patterns and would like to use this methodology in my new applications. Where I'm struggling is finding a clear, concise beginners guide for EF4 which doesn't assume knowledge of EF1. The specific questions I need answered are: Code first / model first? Pros/cons in regards to EF4 (ie what happens if I do code first, change the code at a later date and need to regenerate my DB model - Does the data get preserved and transformed or dropped?) Assuming I'm going code-first (I'd like to see how EF4 converts that to a DB schema) how do I actually get started? Quite often I've seen articles with entity diagrams stating "So this is my entity model, now I'm going to ..." - Unfortunately, I'm unclear if they're created the model in the designer, saved it to generate code then stopped any further auto-code generation -or- They've coded (POCO)? classes and the somehow imported them into the deisgner view? I suppose what I really need is an understanding of where the "magic" comes from and how to add it myself if I'm not just generating an EF model directly from a DB. I'm aware the question is a little vague but I don't know what I don't know - So any input / correction / clarification appreciated. Needless to say, I don't expect anyone to sit here and teach me EF - I'd just like some good tutorials/forums/blogs/etc. for complete entity newbies Many thanks in advance

• Usability for content editors: Drupal or PHP framework?

  - by Jim

  Greetings: I am going to develop a basic Web site that supports some custom content types, is multilingual, and has content moderation workflow for a restricted group of content editors. This seems like an obvious choice for Drupal, except... the content editors will have little computer experience. In my opinion, that is a show-stopper for Drupal. For example, placing arbitrary inline images in content is a task that WordPress does well. I find Drupal's alternatives (IMCE, img_assist, etc.) clunky and not well integrated, and that will be a problem for this group of content editors. Also, none of the Drupal content workflow modules I tried seemed well-integrated; they all had a "tacked on" feel to them. As an admin I can understand why an "Accessible content" menu item (via Module Grants module) is necessary to view draft content (fixed in D7 but I can't wait for all the modules to be ported), but I'm pretty sure it'll confuse the content editors. An alternative is to use a PHP framework. I've read a few threads suggesting that it will take roughly the same amount of time using a good framework as it will to bend Drupal to my willing... maybe wishful thinking? I'm looking at Symfony, which gives me a basic auto-generated back-end, but which I believe I can customize to my heart's content. How do you make Drupal accessible to non-savvy content editors? If you recommend a PHP framework, which one? TIA!

• IE8 CSS Table Effect

  - by Ian

  I've been trying to make this cross browser (specifically IE), but I do not want to use tables. I will not be able to specify the container width with CSS because its contents (the image) will dynamically change with Javascript, so I need the container to 'auto-size' horizontally. The desired effect would be a centered image with two sets of text (one of the left and one of the left) directly underneath the image, aligned to it's inner edges. Example (Doesn't work on IE): http://pastehtml.com/view/19pbyw9.html <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> #container { display:table; } </style> </head> <body> <center> <div id="container"> <img src="http://www.google.com/intl/en_ALL/images/srpr/logo1w.png" alt="" /><br /> <span style="float: left;">test</span> <span style="float: right; text-align: right;">test2</span> </div> </center> </body> </html>

• Publish failed using Ant publisher (Eclipse/datanucleus).

  - by aronp

  Dear All, I am being driven mad the following (apparently hard) error from eclipse. Publish failed using Ant publisher Resource is out of sync with the file system: '/MyServlet/build/classes/com/inver/hotzones/database/BaseNetworkData.class'. I have seen comments on similar errors where refreshing eclipses view of the project helps but it is not helping me. Have tried cleaning the project, removing it from the webserver, deleting war files but cant seem to clear it. I have reset my TMPDIR variable so that it uses a directory on the same filesystem as that appeared to be another possible cause. The error occurs on classes which have been enhanced by datanuculeus. I have auto-enhance on the project. The other references to this problem indicate that it is due to Eclipses view of the project being out of step with the filesystem, and I am guessing that this has something to do with thedata nucleus enhancement. Any ideas? Thanks. I am using Eclipse 3.5.2 with latest datanucleus pluggins. Stack trace org.eclipse.core.runtime.CoreException: Resource is out of sync with the file system: '/MyServlet/build/classes/com/inver/hotzones/database/BaseNetworkData.class'. at org.eclipse.jst.server.generic.core.internal.publishers.AbstractModuleAssembler.copyModule(AbstractModuleAssembler.java:172) at org.eclipse.jst.server.generic.core.internal.publishers.WarModuleAssembler.assemble(WarModuleAssembler.java:31) at org.eclipse.jst.server.generic.core.internal.publishers.AntPublisher.assembleModule(AntPublisher.java:167) at org.eclipse.jst.server.generic.core.internal.publishers.AntPublisher.publish(AntPublisher.java:128) at org.eclipse.jst.server.generic.core.internal.GenericServerBehaviour.publishModule(GenericServerBehaviour.java:82) at org.eclipse.wst.server.core.model.ServerBehaviourDelegate.publishModule(ServerBehaviourDelegate.java:949) at org.eclipse.wst.server.core.model.ServerBehaviourDelegate.publishModules(ServerBehaviourDelegate.java:1039) at org.eclipse.wst.server.core.model.ServerBehaviourDelegate.publish(ServerBehaviourDelegate.java:872) at org.eclipse.wst.server.core.model.ServerBehaviourDelegate.publish(ServerBehaviourDelegate.java:708) at org.eclipse.wst.server.core.internal.Server.publishImpl(Server.java:2731) at org.eclipse.wst.server.core.internal.Server$PublishJob.run(Server.java:278) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

• db:migrate creates sequences but doesn't alter table?

  - by RewbieNewbie

  Hello, I have a migration that creates a postres sequence for auto incrementing a primary identifier, and then executes a statement for altering the column and specifying the default value: execute 'CREATE SEQUENCE "ServiceAvailability_ID_seq";' execute <<-SQL ALTER TABLE "ServiceAvailability" ALTER COLUMN "ID" set DEFAULT NEXTVAL('ServiceAvailability_ID_seq'); SQL If I run db:migrate everything seems to work, in that no errors are returned, however, if I run the rails application I get: Mnull value in column "ID" violates not-null constraint I have discovered by executing the sql statement in the migration manually, that this error is because the alter statement isn't working, or isn't being executed. If I manually execute the following statement: CREATE SEQUENCE "ServiceAvailability_ID_seq; I get: error : ERROR: relation "serviceavailability_id_seq" already exists Which means the migration successfully created the sequence! However, if I manually run: ALTER TABLE "ServiceProvider" ALTER COLUMN "ID" set DEFAULT NEXTVAL('ServiceProvider_ID_seq'); SQL It runs successfully and creates the default NEXTVAL. So the question is, why is the migration file creating the sequence with the first execute statement, but not altering the table in the second execute? (Remembering, no errors are output on running db:migrate) Thank you and apologies for tl:dr

• is this uibutton autoreleased ?

  - by dubbeat

  HI This is just a question to check my sanity really. I'm hunting memory leaks that show up in instruments but not the static analyzer. In one spot the analyzer is pointing to this block of code UIButton *randomButton = [UIButton buttonWithType:UIButtonTypeRoundedRect ]; randomButton.frame = CGRectMake(205, 145, 90, 22); // size and position of button [randomButton setTitle:@"Random" forState:UIControlStateNormal]; randomButton.backgroundColor = [UIColor clearColor]; randomButton.adjustsImageWhenHighlighted = YES; [randomButton addTarget:self action:@selector(getrandom:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:randomButton]; For some reason I thought the above code would auto release the button because I'm not calling init or alloc? If I add [randombutton release] at the bottom of the code my button fails to show. Could somebody describe to me the correct way to release a button from memory that is created in the above way? Or would I be better off making the button a class variable and sticking the release in the dealloc method?

• Switch statement usage - C

  - by Jamie Keeling

  Hello, I have a thread function on Process B that contains a switch to perform certain operations based on the results of an event sent from Process A, these are stored as two elements in an array. I set the first element to the event which signals when Process A has data to send and I have the second element set to the event which indicates when Process A has closed. I have began to implement the functionality for the switch statement but I'm not getting the results as I expect. Consider the following: // //Thread function DWORD WINAPI ThreadFunc(LPVOID passedHandle) { for(i = 0; i < 2; i++) { ghEvents[i] = OpenEvent(EVENT_ALL_ACCESS, FALSE, TEXT("Global\\ProducerEvents")); if(ghEvents[i] == NULL) { getlasterror = GetLastError(); } } dwProducerEventResult = WaitForMultipleObjects( 2, ghEvents, FALSE, INFINITE); switch (dwProducerEventResult) { case WAIT_OBJECT_0 + 0: { //Producer sent data //unpackedHandle = *((HWND*)passedHandle); MessageBox(NULL,L"Test",L"Test",MB_OK); break; } case WAIT_OBJECT_0 + 1: { //Producer closed ExitProcess(1); break; } default: return; } } As you can see if the event in the first array is signalled Process B should display a simple message box, if the second array is signalled the application should close. When I actually close Process A, Process B displays the message box instead. If I leave the first case blank (Do nothing) both applications close as they should. Furthermore Process B sends data an error is thrown (When I comment out the unpacking): Have I implemented my switch statement incorrectly? I though I handled the unpacking of the HWND correctly too, any suggestions? Thanks for your time.

• Mocking attributes - C#

  - by bob

  I use custom Attributes in a project and I would like to integrate them in my unit-tests. Now I use Rhino Mocks to create my mocks but I don't see a way to add my attributes (and there parameters) to them. Did I miss something, or is it not possible? Other mocking framework? Or do I have to create dummy implementations with my attributes? example: I have an interface in a plugin-architecture (IPlugin) and there is an attribute to add meta info to a property. Then I look for properties with this attribute in the plugin implementation for extra processing (storing its value, mark as gui read-only...) Now when I create a mock can I add easily an attribute to a property or the object instance itself? EDIT: I found a post with the same question - link. The answer there is not 100% and it is Java... EDIT 2: It can be done... searched some more (on SO) and found 2 related questions (+ answers) here and here Now, is this already implemented in one or another mocking framework?

• Broken ssl, what to do

  - by TIT

  I have a site and i implemented ssl there. but when i browse it, the security seals dont come. i asked to godaddy, they replaid: Thank you for contacting online support. I cannot replicate the issue you have described. The error you described is caused by the way your site has been designed. If you receive this error, you have a combination of secure and non-secure objects on the page. For example, if your secure website was https://www.domain.tld and you added an object (an image, script, flash file, etc.) to that page that was located at http://www.domain.tld/image.jpg, you would break the seal. You will need to change your design to link to objects using https (ie https://www.domain.tld/image.jpg) or modify your site design to use relative paths (/image.jpg). This error can only be corrected by modifying your site design. Please contact your web designer or the manufacturer of your web design software if you require additional assistance modifying your site design. but the problem is i made everything,all my images javascripts are unders https, but the seal still not coming, saying: some content insecure. what is the problem.

• does anyone know of good delphi docking components?

  - by X-Ray

  we'd like to add movable panels to an application. presently we've used DevExpress docking library but have found them to be disappointingly quirky & difficult to work with. it also has some limitations that aren't so great. auto-hide, pinning, and moving of pages by drag-and-drop are all features we'd like to use. the built-in delphi docking doesn't seem to be full-featured enough to do the things we need (also see sample below). perhaps i should dig deeper into delphi's docking abilities...my initial impression is that they seem very toolbar-oriented rather than something i can drop a frame into. i'm not experienced at docking topics. my only experience has been with the DevExpress docking library where i needed to programmatically create & dock panels. is it my imagination or are DevExpress's products unduly difficult to use/learn? the DevExpress Ribbon Bar component compared to the d2009 Ribbon Bar was certainly a useful experience. i will migrate to the d2009 Ribbon Bar as soon as convenient to do so. it was refreshingly straight-forward to learn and use. a sharp contrast compared to the DevExpress equivalent. if it takes 4x as longer to make it using the DevExpress equivalent, it's time to change direction. what would you suggest in regard to the docking library? thank you for your suggestions/comments!

• What is the most efficient way to display decoded video frames in Qt?

  - by Jason

  What is the fastest way to display images to a Qt widget? I have decoded the video using libavformat and libavcodec, so I already have raw RGB or YCbCr 4:2:0 frames. I am currently using a QGraphicsView with a QGraphicsScene object containing a QGraphicsPixmapItem. I am currently getting the frame data into a QPixmap by using the QImage constructor from a memory buffer and converting it to QPixmap using QPixmap::fromImage(). I like the results of this and it seems relatively fast, but I can't help but think that there must be a more efficient way. I've also heard that the QImage to QPixmap conversion is expensive. I have implemented a solution that uses an SDL overlay on a widget, but I'd like to stay with just Qt since I am able to easily capture clicks and other user interaction with the video display using the QGraphicsView. I am doing any required video scaling or colorspace conversions with libswscale so I would just like to know if anyone has a more efficient way to display the image data after all processing has been performed. Thanks.

• tabBarController and navigationControllers in landscape mode, episode II

  - by unforgiven

  I have a UITabBarController, and each tab handles a different UIViewController that pushes on the stack new controllers as needed. In two of these tabs I need, when a specific controller is reached, the ability to rotate the iPhone and visualize a view in landscape mode. After struggling a lot I have found that it is mandatory subclassing UITabBarController to override shouldAutorotateToInterfaceOrientation. However, if i simply return YES in the implementation, the following undesirable side effect arises: every controller in every tab is automatically put in landscape mode when rotating the iPhone. Even overriding shouldAutorotateToInterfaceOrientation in each controller to return NO does not work: when the iPhone is rotated, the controller is put in landscape mode. I implemented shouldAutorotateToInterfaceOrientation as follows in the subclassed UITabBarController: (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { if([self selectedIndex] == 0 || [self selectedIndex] == 3) return YES; return NO; } So that only the two tabs I am interested in actually get support for landscape mode. Is there a way to support landscape mode for a specific controller on the stack of a particular tab? I tried, without success, something like (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { if([self selectedIndex] == 0 || [self selectedIndex] == 3) { if ([[self selectedViewController] isKindOfClass: [landscapeModeViewController class]]) return YES; } return NO; } Also, I tried using the delegate method didSelectViewController, without success. Any help is greatly appreciated. Thank you.

• Are licenses relevant for small code snippets?

  - by Martin

  When I'm about to write a short algorithm, I first check in the base class library I'm using whether the algorithm is implemented in it. If not, I often do a quick google search to see if someone has done it before (which is the case, 19 times out of 20). Most of the time, I find the exact code I need. Sometimes it's clear what license applies to the source code, sometimes not. It may be GPL, LGPL, BSD or whatever. Sometimes people have posted a code snippet on some random forum which solves my problem. It's clear to me that I can't reuse the code (copy/paste it into my code) without caring about the license if the code is in some way substantial. What is not clear to me is whether I can copy a code snippet containing 5 lines or so without doing a license violation. Can I copy/paste a 5-line code snippet without caring about the license? What about one-liner? What about 10 lines? Where do I draw the line (no pun intended)? My second problem is that if I have found a 10-line code snippet which does exactly what I need, but feel that I cannot copy it because it's GPL-licensed and my software isn't, I have already memorized how to implement it so when I go around implementing the same functionality, my code is almost identical to the GPL licensed code I saw a few minutes ago. (In other words, the code was copied to my brain and my brain after that copied it into my source code).

• Problem with saveToFile

  - by zp26

  Hi, I have a problem with a NSData writeToFile. I have implemented the code below but i have an anomaly. When i run my program on the simulator, the new file is created and the informations are stored; when i build the app in my device , the file isn't created. The debug don't give me any error but don/t save anything. Can you help me? Thanks so much and sorry for my english. -(void)saveXML:(NSString*)name:(float)x:(float)y:(float)z{ NSMutableData *data = [NSMutableData data]; NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data]; [archiver setOutputFormat:NSPropertyListXMLFormat_v1_0]; [archiver encodeFloat:x forKey:@"x"]; [archiver encodeFloat:y forKey:@"y"]; [archiver encodeFloat:z forKey:@"z"]; [archiver encodeObject:name forKey:@"name"]; [archiver finishEncoding]; BOOL result = [data writeToFile:@"XML Position" atomically:YES]; if(result) [self updateTextView:@"success"]; [archiver release]; }
