  • Height of tableHeaderView seems to be 0

    - by gabac
    I tried to override the second tableHeaderView. But it seems that the height of it in the method heightForHeaderInSection seems to be 0. Can't explain it, do I have to put it in a iVar because in the viewForHeaderInSection I can set the view without any problems. - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { if(section == 0) return @"Adding a new list"; else return @"Other lists"; } - (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section { if(section == 0) { return tableView.tableHeaderView; } else { UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(10, 10, 100, 50)] autorelease]; view.backgroundColor = [UIColor redColor]; return view; } } - (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section { if(section == 0) return tableView.tableHeaderView.frame.size.height; else return 30; }

  • Why would a UIDatePicker with no functionality, added to my app via IB, cause my app to crash?

    - by BeachRunnerJoe
    I just added a UIDatePicker to my iPad app using IB, linked it to its outlet in the code, saved it in IB, added the UIPickerViewDelegate to my UIViewController in the code, as well as added the UIDatePicker outlet in code. When I build and run, the app launches, but will crash intermittently when I attempt to open the popover view that contains the datepicker. I say intermittently because the popover view will occasionally open successfully, but never more than once (it always crashes the second time you open the popover, if it doesn't crash the first time). Also, in the console, I get the following messsage objc[594]: FREED(id): message lastClickRow sent to freed object=0x6015a70 Why is this happening and how can I fix it? What does that console message indicate? It may be worth mentioning that the popover view also contains a table view along with the datepicker control. Thanks so much in advance for your help!

  • commons-exec: Executing a program on the system PATH?

    - by Stefan Kendall
    I'm trying to execute a program (convert from ImageMagick, to be specific) whose parent folder exists on the path. Ergo, when I run convert from the command line, it runs the command. The following, however, fails: String command = "convert" CommandLine commandLine = CommandLine.parse(command); commandLine.addArgument(...) ... int exitValue = executor.execute(commandLine); If I specify the full path of the convert executable (C:\Program files\...) then this code works. If I don't do this, I get an exception thrown with exit value 4. How do I get commons-exec to recognize the system path?

  • popToRootViewControllerAnimated and dealloc all views

    - by mongeta
    Hello again, I have a UINavigationController that asks for some information and the user navigates until the end, once there, they can Accept or Cancel all the data that has been entered. It doesn't matter wich option they choose, as they always will go to the first view using [UINavigationController popToRootViewControllerAnimated:] The question is, how I can release/deallocate all the views ? For example, they start for view 1 and the end is at view 8, once they go directly to the 1 from the 8, how I can release view 2,3,4,5,6,7,8 ? thanks, regards, m.

  • Using a constructor for return.

    - by Fecal Brunch
    Hi, Just a quick question. I've written some code that returns a custom class Command, and the code I've written seems to work fine. I was wondering if there are any reasons that I shouldn't be doing it this way. It's something like this: Command Behavior::getCommand () { char input = 'x'; return Command (input, -1, -1); } Anyway, I read that constructors aren't meant to have a return value, but this works in g++. Thanks for any advice, Rhys

  • UIView Obscuring Other Views

    - by Matt Long
    I cannot figure out what is obscuring my buttons. The first image shows the buttons that I want to click. They are clickable while the view is contracted like this, but when the view is expanded like in the second image, the buttons are no longer clickable. There seems to be another view obscuring the buttons. Any thoughts on what might be causing that? If not, any idea how I can figure out what view is getting the tap events when I tap in that area? Thanks. -Matt

  • UIVIewController wrong position before rotate

    - by zegnus
    I have the starter point of my application this window (white background): - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { mainScreen = [[MainScreenController alloc] initWithNibName:@"MainScreenController" bundle:[NSBundle mainBundle]]; // add it to the main window [window addSubview:[mainScreen view]]; // show view [window makeKeyAndVisible]; NSLog(@"started"); return YES; } And MainScreenController is an UIViewController with (blackBackground) created by the Interface Builder. The application executes perfectly but the first time, the black view is moved up like the height of the status iphone pannel (leaving white rectangle at the bottom). If I rotate the iPhone twice, the view is perfectly positioned in the right place, filling all the screen with the black background. Any idea? Thanks!

  • InvalidOperationException when executing SqlCommand with transaction

    - by Serhat Özgel
    I have this code, running parallel in two separate threads. It works fine for a few times, but at some random point it throws InvalidOperationException: The transaction is either not associated with the current connection or has been completed. At the point of exception, I am looking inside the transaction with visual studio and verify its connection is set normally. Also command.Transaction._internalTransaction. _transactionState is set to Active and IsZombied property is set to false. This is a test application and I am using Thread.Sleep for creating longer transactions and causing overlaps. Why may the exception being thrown and what can I do about it? IDbCommand command = new SqlCommand("Select * From INFO"); IDbConnection connection = new SqlConnection(connectionString); command.Connection = connection; IDbTransaction transaction = null; try { connection.Open(); transaction = connection.BeginTransaction(); command.Transaction = transaction; command.ExecuteNonQuery(); // Sometimes throws exception Thread.Sleep(forawhile); // For overlapping transactions running in parallel transaction.Commit(); } catch (ApplicationException exception) { if (transaction != null) { transaction.Rollback(); } } finally { connection.Close(); }

  • Removing zombie locks in Subversion

    - by ThatBlairGuy
    I'm trying to find a way to remove zombie locks using the Subversion command line tools. The eventual goal is to do this from a hook script, but I haven't been able to work out the command line to use when you only have a physical repository path. (Using svnadmin rmlocks only seems to work for locks which exist in the HEAD revision.) Ideally, I'd like to do this via the post-commit hook script using the command line tools. (I'm aware of the python script for this purpose, but we'd prefer not to install python on that server for this single use.) We're a .NET shop, so creating a tool with the SharpSVN library is also a possibility, but the only unlock capability there appears to be in the SVNClient class. So it's really two questions: Is there a way to do this with the command line tools? If not, is there a way to do it from SharpSVN? (Or perhaps another library?)

  • CAsyncSocket and ThreadPool problem

    - by zabulus
    I have a server application with such structure: There is one object, call him Server, that in endless cycle listens and accepts connections. I have descendant class from CAsyncSocket, that has overriden event OnReceive, call him ProxySocket. Also I have a thread pool with early created threads. When connection is received by server object he accepts the new connection on the new object ProxySocket. When data arrives to the ProxySocket, he creates a command object and gives it to thread pool. In this command object I giving the socket handle of a ProxySocket. When new object of command is creating - I creating a new Socket in working thread and attach handle to it. My issue is next: When command ends, socket doesn't close, I just detach handle it and set CSocket handle to INVALID_SOCKET value, as planned. But my first ProxySocket object doesn't receives messages of new data receiving after that. How can I solve this?

    I have three tables that I need to join together and get a combination of results. I have tried using left/right joins but they don't give the desired results.

  • Mapping composite foreign keys in a many-many relationship, with overlapping components.

    - by Kirk Broadhurst
    I have a Page table and a View table. There is a many-many relationship between these two via a PageView table. Unfortunately all of these tables need to have composite keys (for business reasons). Page has a primary key of (PageCode, Version), View has a primary key of (ViewCode, Version). PageView obviously enough has PageCode, ViewCode, and Version. The FK to Page is (PageCode, Version) and the FK to View is (ViewCode, Version) Makes sense and works, but when I try to map this in Entity framework I get Error 3021: Problem in mapping fragments...: Each of the following columns in table PageView is mapped to multiple conceptual side properties: PageView.Version is mapped to (PageView_Association.View.Version, PageView_Association.Page.Version) So clearly enough, EF is having a complain about the Version column being a common component of the two foreign keys. Obviously I could create a PageVersion and ViewVersion column in the join table, but that kind of defeats the point of the constraint, i.e. the Page and View must have the same Version value. Has anyone encountered this, and is there anything I can do get around it? Thanks!

  • PDF to PNG Processor - Paperclip

    - by Josh Crowder
    I am trying to develop a system in which a user can upload a slideshow (pdf) and it'll export each slide as a png. After some digging around I came across a post on here that suggested using a processor. I've had a go, but I cant get the command to run, if it is running then I don't know what is happening because no errors are being shown. Any help would be appreciated! module Paperclip class Slides < Processor def initialize(file, options = {}, attachment = nill) super @file = file @instance = options[:instance] @current_format = File.extname(@file.path) @basename = File.basename(@file.path, @current_format) end def make dst = Tempfile.new( [ @basename, @format].compact.join(".")) dst.binmode command = <<-end_command -size 640x300 #{ File.expand_path(dst.path) } tester.png end_command begin success = Paperclip.run("convert", command.gsub(/\s+/, " "))) rescue PaperclipCommandLineError raise PaperclipError, "There was an error processing the thumbnail for #{@basename}" end end end end I think my problem is with the convert command... When I run that command by hand, it works but it doesn't give the details of each slide it just executes it. What I need to happen is once its made all the slides, pass back the data to a new model... or I know where all the slides are, but once I get to that point I'm not sure what todo.

  • Two UITabBarControllers and Autorotation

    - by optimisticmonkey
    I have two UITabBarControllers in my mainwnidow.nib wired to my appdelegate. In my app delegate, I can load either one: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //either [window addSubview:tabBarController.view]; //or [window addSubview:tabBar2Controller.view]; [window makeKeyAndVisible]; } and autorotation works. If I add both (with the expectation to swap between them later): [window addSubview:tabBarController.view]; [window addSubview:tabBar2Controller.view]; then autorotation stops working...everything is always portrait. Thanks in advance for any tips...

  • Iphone: Problem with moving back and forth between two UIViewController

    - by Harry Pham
    Let me first describe the context of the problem. I have 2 UIViewController call AdminViewController and ButtonReorderViewController. AdminViewController contain 1 button. ButtonReorderViewController contains 1 button and 1 picture. Button in AdminViewController tie to an event call goToReorderButton. The content of goToReorderButton are below: ButtonReorderViewController *buttonReorder = [[ButtonReorderViewController alloc] initWithNibName:@"ButtonReorderViewController" bundle:[NSBundle mainBundle]]; UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:buttonReorder]; //Add a Navigation Controller to the root view [navController setNavigationBarHidden:TRUE]; buttonReorder = (ButtonReorderViewController *) navController; [[buttonReorder view] setFrame:CGRectMake(0, -20, 320, 470)]; [self.view addSubview:buttonReorder.view]; I use UINavigationController to allow me to swipe left and right.So I am in AdminViewController, and I click on goToReorderButton, it load ButtonReorderViewController. I am able to swipe left and right (awesome !!!) So I click the button in ButtonReorderViewController call goToAdmin, simply to go back to the AdminViewController -(void) goToAdmin{ [self.view removeFromSuperview]; } However, as soon as I go back to AdminViewController, I cant click anything at all. The program does not seg fault, it just that I cant click the button at all. if I remove the line buttonReorder = (ButtonReorderViewController *) navController; inside goToReorderButton, then everything work fine. Any idea how to fix this?
