  • iPhone memory management

    - by Prazi
    I am newbie to iPhone programming. I am not using Interface Builder in my programming. I have some doubt about memory management, @property topics in iPhone. Consider the following code @interface LoadFlag : UIViewController { UIImage *flag; UIImageView *preview; } @property (nonatomic, retain) UIImageView *preview; @property (nonatomic, retain) UIImage *flag; @implementation @synthesize preview; @synthesize flag; - (void)viewDidLoad { flag = [UIImage imageNamed:@"myImage.png"]]; NSLog(@"Preview: %d\n",[preview retainCount]); //Count: 0 but shouldn't it be 1 as I am retaining it in @property in interface file preview=[[UIImageView alloc]init]; NSLog(@"Count: %d\n",[preview retainCount]); //Count: 1 preview.frame=CGRectMake(0.0f, 0.0f, 100.0f, 100.0f); preview.image = flag; [self.view addSubview:preview]; NSLog(@"Count: %d\n",[preview retainCount]); //Count: 2 [preview release]; NSLog(@"Count: %d\n",[preview retainCount]); //Count: 1 } When & Why(what is the need) do I have to set @property with retain (in above case for UIImage & UIImageView) ? I saw this statement in many sample programs but didn't understood the need of it. When I declare @property (nonatomic, retain) UIImageView *preview; statement the retain Count is 0. Why doesn't it increase by 1 inspite of retaining it in @property. Also when I declare [self.view addSubview:preview]; then retain Count increments by 1 again. In this case does the "Autorelease pool" releases for us later or we have to take care of releasing it. I am not sure but I think that the Autorelease should handle it as we didn't explicitly retained it so why should we worry of releasing it. Now, after the [preview release]; statement my count is 1. Now I don't need UIImageView anymore in my program so when and where should I release it so that the count becomes 0 and the memory gets deallocated. Again, I am not sure but I think that the Autorelease should handle it as we didn't explicitly retained it so why should we worry of releasing it. What will happen if I release it in -(void) dealloc method In the statement - flag = [UIImage imageNamed:@"myImage.png"]]; I haven't allocated any memory to flag but how can I still use it in my program. In this case if I do not allocate memory then who allocates & deallocates memory to it or is the "flag" just a reference pointing to - [UIImage imageNamed:@"myImage.png"]];. If it is a reference only then do i need to release it. Thanks in advance.

  • Using UNC path as collections location in Mecurial IIS6 Server2003

    - by Chris M
    I'm running the latest Mercurial and Python 2.6; IIS6 is using the wildcard ISAPI method to attach the site to the Mecurial hgwebdir_wsgi [paths] \ = \\COMP3254\TestRepo\* [web] baseurl = / allow_push = * push_ssl = false style = monoblue The setup works perfectly if I reference the local drive E:\repo* but doesnt work if I specify the network as above; I've given the server (MERCDEV01$) full permissions on the shared folder on COMP3254, I can't think of any other reason it wouldn't work. Any ideas?

  • How do I get the CPU speed and total physical ram in C#?

    - by edude05
    I need a simple way of checking how much ram and fast the CPU of the host PC is. I tried WMI however the code I'm using private long getCPU() { ManagementClass mObject = new ManagementClass("Win32_Processor"); mObject.Get(); return (long)mObject.Properties["MaxClockSpeed"].Value; } Throws a null reference exception. Furthermore, WMI queries are a bit slow and I need to make a few to get all the specs. Is there a better way?

  • Peek ahead when iterating an array in PHP 5.2

    - by pako
    Is it possible to "peek ahead" while iterating an array in PHP 5.2? For example, I often use foreach to manipulate data from an array: foreach($array as $object) { // do something } But I often need to peek at the next element while going through the array. I know I could use a for loop and reference the next item by it's index ($array[$i+1]), but it wouldn't work for associative arrays. Is there any elegant solution for my problem, perhaps involving SPL?

  • java web application best practices

    - by Bruce
    Hi all I'm trying to figure out the optimum way to develop and release a fairly simple web application, and I'm running into several problems. I'll outline the decisions I've made, because somewhere I've clearly gone off the rails.. Hugely grateful for any help! I have what I think is a fairly simple web application. It contains a couple of jsps that reference a couple of java beans, and the usual static html, js, css and images. Decision 1) I wanted to have a clear and clean release procedure, such that I could develop on my local machine and then release reliably to a production machine. I therefore made the decision to package the application into a war file (including all the static resources), to minimize the separate bits and pieces I would need to release. So far so good? Decision 2) I wanted things on my local machine to be as similar as possible to the production environment. So in my html, for example, I may have a reference to a static file such as http://static.foo.com/file . To keep this code working seamlessly on dev and prod, I decided to put static.foo.com in my /etc/hosts when developing locally, so that all the urls work correctly without changing anything. Decision 3) I decided to use eclipse and maven to give me a best practice environment for administering and building my project. So I have a nice tight set up now, except that: Every time I want to change anything in development, like one line in an html file, I have to rebuild the entire project and then wait for tomcat to load the war before I can see if it's what I wanted. So my questions are: 1) Is there a way to connect up eclipse and tomcat so that I don't have to rebuild the war each time? ie tomcat is looking straight at my actual workspace to serve up the static files? 2)I think I'm maybe making things harder by using /etc/hosts to reflect production urls - is there a better way that doesn't involve manually changing over urls (relative urls are fine of course, but where you have many subdomains, say one for static files and one for dynamic, you have to write out the full path, surely?) 3) Is this really best practice?? How do people set things up so that they balance the requirement for an automated, all-encompassing build process on the one hand, and the speed and flexibility to be able to develop javascript and html and css quickly, as quickly as if one just pointed apache at the directory and developed live? What do people find works? Many thanks!

  • jQuery shifting blocks of content to top on click/toggle

    - by JEBR0
    I have blocks of content that are toggled on/off via jQuery and I want to have the most recent one clicked to shuffle to the top of the content area. There are 4 that can be enabled and if you do it in a random order, or even intended order, it is hard to tell which one you just opened if it's not in the view window. Here is the page for reference http://jonrcoulter.com/

  • Is it possible to use Boehm garbage collector only for the part of the program?

    - by bialix
    I've read article in LinuxJournal about Boehm-Demers-Weiser garbage collector library. I'm interesting to use it in my library instead of my own reference counting implementation. I have only one question: is it possible to use gc only for my shared library and still use malloc/free in the main application? I'm not quite understand how gc checks the heap so I'm worrying about performance of gc in that case and possible side effects.

  • Facebook Like Button (<fb:like>) Height Always 80px

    - by David
    Why is the height of my Facebook Like button (technically the iframe that gets generated) always getting set to 80px? Example page is here: http://www.davidkasper.net/test.html I am using the javascript sdk and have had it work on other pages but for some reason the height will not change dynamically on this one! I can even do something like <fb:like style="height:40px"> and that will indeed set the visible height, but the iframe will still be 80px, whereas I can see it changing in the demo at http://developers.facebook.com/docs/reference/plugins/like

  • Basic GUI Event Handling Questions C#

    - by JHarley1
    Good Afternoon, I have some very basic questions on GUI Event Handling. Firstly with C# how can we link events to objects - I am guessing event handlers? If so can each handler use separate code? - How can the event handler locate the objects it must manipulate? I have a rough idea of how it works in JAVA. Pointing me towards a reference would be fine - I have already trawled Google for answers to no avail. Many Thanks, J
