  • HOw Do I update from table-2 to table-1

    - by mathew
    HI what is the wrong in this code?? i have set it 24 hours to update the value in the table.but the problem is if $row is empty then it inserts value from table-2 but after 24 hours it wont update the value. what I want is it must delete the existing value and insert new one(random value) or it must update the same $row with new value what ever... if ($row == 0){ mysql_query("INSERT INTO table-1 (regtime,person,location,address,rank,ip,geocode) SELECT NOW(),person,location,address,rank,ip,geocode FROM table-2 ORDER BY RAND() LIMIT 1");}else{ mysql_query("UPDATE table-1 SELECT regtime=NOW(), person=person, location=location, address=address, rank=rank, ip=ip, geocode=geocode FROM table-2 ORDER BY RAND() LIMIT 1");}

  • Loading views dynamically

    - by Dan
    Case 1: I have created View-based sample application and tried execute below code. When I press on "Job List" button it should load another view having "Back Btn" on it. In test function, if I use [self.navigationController pushViewController:jbc animated:YES]; nothing gets loaded, but if I use [self presentModalViewController:jbc animated:YES]; it loads another view haveing "Back Btn" on it. Case 2: I did create another Navigation Based Applicaton and used [self.navigationController pushViewController:jbc animated:YES]; it worked as I wanted. Can someone please explain why it was not working in Case 1. Does it has something to do with type of project that is selected? @interface MWViewController : UIViewController { } -(void) test; @end @interface JobViewCtrl : UIViewController { } @end @implementation MWViewController (void)viewDidLoad { UIButton* btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(80, 170, 150, 35); [btn setTitle:@"Job List!" forState:UIControlStateNormal]; [btn addTarget:self action:@selector(test) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:btn]; [super viewDidLoad]; } -(void) test { JobViewCtrl* jbc = [[JobViewCtrl alloc] init]; [self.navigationController pushViewController:jbc animated:YES]; //[self presentModalViewController:jbc animated:YES]; [jbc release]; } (void)dealloc { [super dealloc]; } @end @implementation JobViewCtrl -(void) loadView { self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; self.view.backgroundColor = [UIColor grayColor]; UIButton* btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(80, 170, 150, 35); [btn setTitle:@"Back Btn!" forState:UIControlStateNormal]; [self.view addSubview:btn]; } @end

  • how to made one-to-one bidirectional relationships in grails?

    - by user369759
    I have two domain classes and want to have one-to-one BIDIRECTIONAL relation between them. I write: class Person { Book book; String name Integer age Date lastVisit static constraints = { book unique: true // "one-to-one". Without that = "Many-to-one". } } class Book { String title Date releaseDate String ISBN static belongsTo = [person:Person] // it makes relationship bi-directional regarding the grails-docs } So, i want to have bi-directional, i could NOT find link from Book to Person in generated SQL: CREATE TABLE `book` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `version` bigint(20) NOT NULL, `isbn` varchar(255) NOT NULL, `release_date` datetime NOT NULL, `title` varchar(255) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=latin1 So then it means it is not bidirectional then? How to make bidirectional?

  • How can I view javadocs that have been added to a maven repository?

    - by Coderer
    I know I can use maven to pull the javadocs for an artifact (if they've been added), which should come through as a JAR (right?), which I can then unpack and browse. My problem is, I'm trying to figure out which of a series of artifacts have the particular package I'm hunting for. I could download a half-dozen javadoc packages, unpack all of them, then open the index files one at a time, but that sounds like it would be pretty unpleasant. There must be a better way! I noticed that Nexus supports javadoc artifact browsing, but apparently only in the Pro version (which we do not have, and are unlikely to get any time soon). I'd prefer a GUI solution, though I'd settle for a command line answer, provided it's something along the lines of showmethedocs groupId:artifactId [version].

  • Which Firefox extension checks html markup when you view source?

    - by Haroldo
    I used to have a great firefox addon for this and i can't remember the name of it.. when you looked at the source it would sit at the bottom (like firebug) and check your html markup and suggest things like "doctype given is html4.0, looks like xhtml strict" etc i though it was the web developer toolbar but that doesnt seem to add anything to the bottom of ym source pane?

  • Can a python view template be made to be 'safe/secure' if I make it user editable?

    - by Blankman
    Say I need to have a templating system where a user can edit it online using an online editor. So they can put if tags, looping tags etc., but ONLY for specific objects that I want to inject into the template. Can this be made to be safe from security issues? i.e. them somehow outputing sql connection string information or scripting things outside of the allowable tags and injected objects.

  • Magento: Configurable product options not showing on a view page?

    - by Relja
    I have multi-store Magento system and strange things happen when i try to see a configurable product on my main store - the options select lists don't show up at all! And that is the case for the 95% of the products on the main store. But on the other stores it works fine?! I can't see what am I doing wrong. All my products are configurable, all have set simple products with options attached to them, all are set to be visible on all stores (WebsiteIds attribute), all are enabled on all stores, all simple products are in stock and have some stock quantity set. I think if I've done something wrong it would be like that on all stores, not just the main one. I'm totally clueless, please help. I've attached couple of images to see the difference. http://img51.imageshack.us/img51/3224/59155765.jpg http://img196.imageshack.us/img196/8145/98963713.jpg

  • Speed comparison - Template specialization vs. Virtual Function vs. If-Statement

    - by Person
    Just to get it out of the way... Premature optimization is the root of all evil Make use of OOP etc. I understand. Just looking for some advice regarding the speed of certain operations that I can store in my grey matter for future reference. Say you have an Animation class. An animation can be looped (plays over and over) or not looped (plays once), it may have unique frame times or not, etc. Let's say there are 3 of these "either or" attributes. Note that any method of the Animation class will at most check for one of these (i.e. this isn't a case of a giant branch of if-elseif). Here are some options. 1) Give it boolean members for the attributes given above, and use an if statement to check against them when playing the animation to perform the appropriate action. Problem: Conditional checked every single time the animation is played. 2) Make a base animation class, and derive other animations classes such as LoopedAnimation and AnimationUniqueFrames, etc. Problem: Vtable check upon every call to play the animation given that you have something like a vector<Animation>. Also, making a separate class for all of the possible combinations seems code bloaty. 3) Use template specialization, and specialize those functions that depend on those attributes. Like template<bool looped, bool uniqueFrameTimes> class Animation. Problem: The problem with this is that you couldn't just have a vector<Animation> for something's animations. Could also be bloaty. I'm wondering what kind of speed each of these options offer? I'm particularly interested in the 1st and 2nd option because the 3rd doesn't allow one to iterate through a general container of Animations. In short, what is faster - a vtable fetch or a conditional?

  • How can I speed up a 1800-line PHP include? It's slowing my pageload down to 10sec/view

    - by somerandomguy
    I designed my code to put all important functions in a single PHP file that's now 1800 lines long. I call it in other PHP files--AJAX processors, for example--with a simple "require_once("codeBank.php")". I'm discovering that it takes about 10 seconds to load up all those functions, even though I have nothing more than a few global arrays and a bunch of other functions involved. The main AJAX processor code, for example, is taking 8 seconds just to do a simple syntax verification (whose operational function is stored in codeBank.php). When I comment out the require_once, my AJAX response time speeds up from 10sec to 40ms, so it's pretty clear that PHP's trying to do something with those 1800 lines of functions. That's even with APC installed, which is surprising. What should I do to get my code speed back to the sub-100ms level? Am I failing to get the cache's benefit somehow? Do I need to cut that single function bank file into different pieces? Are there other subtle things that I could be doing to screw up my response time? Or barring all that, what are some tools to dig further into which PHP operations are hitting speed bumps?

  • ValueError: Too Many Values to Unpack Aptana Studio 3

I should run this code: from sys import argv script, first, second, third = argv print "The script is called:", script print "Your first variable is:", first print "Your second variable is:", second print "Your third variable is:", third Then enter "python ex13.py first 2nd 3rd" on command line. However, I am using Aptana Studio 3 on Vista and I get the "ValueError: too many values to unpack" error. I am new to Python and Aptana so how can I enter the separate arguments here?

  • How to deal with a Java serialized object whose package changed?

    - by Alex
    I have a Java class that is stored in an HttpSession object that's serialized and transfered between servers in a cluster environment. For the purpose of this explanation, lets call this class "Person". While in the process of improving the code, this class was moved from "com.acme.Person" to "com.acme.entity.Person". Internally, the class remains exactly the same (same fields, same methods, same everything). The problem is that we have two sets of servers running the old code and the new code at the same time. The servers with the old code have serialized HttpSession object and when the new code unserializes it, it throws a ClassNotFoundException because it can't find the old reference to com.acme.Person. At this point, it's easy to deal with this because we can just recreate the object using the new package. The problem then becomes that the HttpSession in the new servers, will serialize the object with the new reference to com.acme.entity.Person, and when this is unserialized in the servers running the old code, another exception will be thrown. At this point, we can't deal with this exception anymore. What's the best strategy to follow for this kind of cases? Is there a way to tell the new servers to serialize the object with the reference to the old package and unserialize references to the old package to the new one? How would we transition to using the new package and forgetting about the old one once all servers run the new code?

  • How do i view the local database version in safari on the iphone?

    - by ~potsed
    I am trying to see the localDatabase version from my iPhone in safari but it is not displaying, according to the docs i am supposed to be able to do this: var db = openDatabase('dbShortName', '', 'dbLongName', 1000); alert(db.version); and it should alert the current version number. It does not. It works in Chrome and safari for the desktop but not the iPhone. Does anybody have some idea why? My next option is to store the version in a separate table, but I would prefer to use the built in system. Thanks in advance.

  • Rails - inheritance hierarchy of classes where an subtipe can play two roles

    - by Miquel
    I need to model Owners and Rentees in an application, so you have stuff that is always owned by someone and can be rented for someone else. I first approached this problem with Single Table Inheritance because both types of person will share all attributes, so you would have a model called Person associated to a table people with Owner and Rentee inheriting from Person. The problem is that Single type inheritance discerns subtypes using a field type and therefore a record in the table can represent either an Owner or a Rentee but not both at the same time, while in the real context you can have an Owner which is renting something from another Owner and therefore that person is at the same time an Owner and a Rentee. How would you approach this problem? Would you use separated tables fro owners and rentees? Is there any other type of table inheritance in Rails?

  • objective C underscore property vs self

    - by user1216838
    I'm was playing around with the standard sample split view that gets created when you select a split view application in Xcode, and after adding a few fields i needed to add a few fields to display them in the detail view. and something interesting happend in the original sample, the master view sets a "detailItem" property in the detail view and the detail view displays it. - (void)setDetailItem:(id) newDetailItem { if (_detailItem != newDetailItem) { _detailItem = newDetailItem; // Update the view. [self configureView]; } i understand what that does and all, so while i was playing around with it. i thought it would be the same if instead of _detailItem i used self.detailItem, since it's a property of the class. however, when i used self.detailItem != newDetailItem i actually got stuck in a loop where this method is constantly called and i cant do anything else in the simulator. my question is, whats the actual difference between the underscore variables(ivar?) and the properties? i read some posts here it seems to be just some objective C convention, but it actually made some difference.
