  • Background image for navigation view (iPhone)

    - by Mladen
    Hi Guys, I am having problems with properly displaying background image of navigation view. Here is the pic: Here is the code: (id)initWithStyle:(UITableViewStyle)style { if (self = [super initWithStyle:style]) { UIImage *image = [UIImage imageNamed: @"bg_table_active.png"]; UIImageView *imageview = [[UIImageView alloc] initWithImage: image]; UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Settings", @"") style:UIBarButtonItemStyleDone target:self action:@selector(GoToSettings)]; self.navigationItem.titleView = imageview; self.navigationItem.rightBarButtonItem = addButton; self.navigationItem.hidesBackButton = TRUE; } return self; } How to make the picture stretch to whole navigation view?

  • How do "modern JVMs" differ from older JVMs?

    - by Lord Torgamus
    Here's a phrase that I heard a lot throughout high school and university computer science classes: "That's not an issue for modern JVMs." Usually this would come up in discussions about overall performance or optimization strategies. It was always treated as a kind of magical final answer, though, as if it makes issues no longer worth thinking about. And that just leads me to wonder: what are the differences between the prototypical "modern JVM" and older JVMs, really?

  • Which design pattern should be used to create an emulator?

    - by Facon
    I have programmed an emulator, but I have some doubts about how to organizate it properly, because, I see that it has some problems about classes connection (CPU <- Machine Board). For example: I/O ports, interruptions, communication between two or more CPU, etc. I need for the emulator to has the best performance and good understanding of the code. PD: Sorry for my bad English. EDITED - Asking for multiple patterns.

    - by KandadaBoggu
    I want to extract a word from a string column of a table. description =========================== abc order_id: 2 xxxx yyy aa mmm order_id: 3 nn kk yw Expected result set order_id =========================== 2 3 Table will at most have 100 rows, text length is ~256 char and column always has one order_id present. So performance is not an issue. In Oracle, I can use REGEXP_SUBSTR for this problem. How would I solve this in MySQL?

  • How to specify unique container styles for heterogenous hierarchies using SL3 and TreeView control

    - by rcecil
    Hello, Just look for strategies that have been successful in rendering hierarchies that represent inheritance structures using SL3/4 TreeViews. I need to render certain nodes differently than others, depending upon what kind of container they are (a choice between things, or simply a list of related things, etc.) So far, I've been very successful with the DataTemplate route: I've been able to use a technique described in Ted Glaza's post "Easy DataTemplateSelectors in Silverlight" (you may have retrieve a Google cache of this page). SO what I'm trying to discover is something on the order of a StyleSelector, not a DataTemplateSelector. I'm considering leveraging my current implementations of Glaza's pattern of selector objects to somehow detect the node type and set the ItemContainerStyle there, but it doesn't seem clear right now. Thanks for your thoughts.

  • Does generation of debug information to JSP classes add much to javac execution time?

    - by Rich
    Hi I am looking looking into the options for tweaking the performance of JBoss 5.1.0 and one of the options available to me is to disable the generation of debug information when compiling JSPs. I know that the presence/absence of debug information for the JVM makes no real difference, but does the generation of that debug information add much to compile time? Thanks in advance Richard

    - by Keith Donegan
    Hi Guys, I am using JQuery's nth-child selector to alter the margin on every 3rd div with a class of photo_post_thumbnail, but it alters it every 2nd div? Can anyone spot what I am doing wrong?

  • Where to go from PHP?

    - by dabito
    I'm a seasoned PHP programmer and I really like the way it works and find it very fun to work with (performance could be improved and some functions renamed, but nothing too serious). However, I took a java seminar and now Im very interested in using GWT for upcomming projects, although I think the learning curve can be steep. Should I really go through with this change (PHP JAVA)? Where to begin?

  • Should I consider Erlang for web mvc?

    - by gotts
    Can I do that? I'm afraid that this can be an overkill and eventually I'll end up with much less productivity than with traditional stack like Ruby/Python/you name it. I understand that you will start with much lower productivity if you start to work with new technology but .. is it potentially worth trying and finally switch to Erlang as the only tool for web development and all the backend stuff. Or is Erlang more suitable for only some high performance backend tasks?

  • innerHTML of dynamically added element not updating in Chrome

    - by Sara Chipps
    I'm modifying a dynamically created input element by setting the innerHTML, when I view the element in the DOM Inspector I can see that the values I passed are in the input. However, I can't see it on the page? Is there a refresh() function that I should be calling after setting the value? I have tried innerText, and value and gotten the same results. Here is how I am setting it: $("input[name='group']")[0].innerHTML = groups; (as far as the JS set and the JQuery selector I have found chrome plugins to be fickle this way)

  • Why is multitasking not supported on the iPhone ?

    - by srikanth rongali
    Many people are saying that Apple has restricted it for better performance. If so Apple should increase the size of RAM to support multitasking. So Apple is not allowing it. Others say that Cocoa Touch applications can't be multitasking as the iPhone has only one window and views on it. I can not understand which is the actual reason for this ? Please clarify me.

  • zoomScale for OS 2.0

    - by sasayins
    Hi, Is there any alternative or work around so that I can use zoomScale in Iphone OS 2.0. It seems the property is only available in Iphone OS 3.0 or later? I have two subviews in my UIScrollView and if the first subview reach a specified scale then it will change to the other subview and save the current scale to zoomScale so that the new subview will apply to the previous scale. Like for example in, scrollViewDidEndZooming, scrollView.zoomScale = scale; When I run my app in Iphone OS 2.0, it gives me error saying invalid zoomScale invalid selector. How can I work around this? Thanks.

  • Need help with jQuery UI Accordion navigationFilter option

    - by theJBRU
    I'm building an accordion for navigation. Each section of the accordion has a set of links. The firing code looks like this: $(document).ready(function() { $(".selector").accordion({ collapsible: true, active: false, navigation: true }); }); This all worked fine and dandy until one of the links in each set was edited to point to a single file, call it foo.html. So now if you navigate to foo.html, the location.href matches every section of the accordion (since each section has a link to it) and that opens all the sections, defeating the purpose of the accordion. So I'm pretty sure I need to use the navigationFilter option but I've googled the living hell out of it and haven't found any examples of how to build the function associated with it. Help me, Stack Overflow!

  • Best way to display a background with a pattern in an iPhone/iPad app

    - by Dr Dork
    Here's an example of the type of background image I'm talking about... Clearly, there's a pattern in it. My question is, if this were an iPad app and the background image was twice the size, would there be any significant benefits to taking advantage of this pattern by tiling the image? Or would it really make no difference in terms of performance and just be easier to load the entire image into a UIImageView? Thanks in advance for all your wisdom!
