  • iPhone: custom UITableViewCell with Interface Builder -> how to release cell objects?

    - by Stefan Klumpp
    The official documentation tells me I've to do these 3 things in order to manage the my memory for "nib objects" correctly. @property (nonatomic, retain) IBOutlet UIUserInterfaceElementClass *anOutlet; "You should then either synthesize the corresponding accessor methods, or implement them according to the declaration, and (in iPhone OS) release the corresponding variable in dealloc." - (void)viewDidUnload { self.anOutlet = nil; [super viewDidUnload]; } That makes sense for a normal view. However, how am I gonna do that for a UITableView with custom UITableViewCells loaded through a .nib-file? There the IBOutlets are in MyCustomCell.h (inherited from UITableViewCell), but that is not the place where I load the nib and apply it to the cell instances, because that happens in MyTableView.m So do I still release the IBOutlets in the dealloc of MyCustomCell.m or do I have to do something in MyTableView.m? Also MyCustomCell.m doesn't have a - (void)viewDidUnload {} where I can set my IBOutlets to nil, while my MyTableView.m does.

  • Sharing Jinja2 templates between Pylons and Django applications

    - by Joe Holloway
    I'm writing a couple of Jinja2 templates that basically implement some common grid layouts. I'd like to be able to share this 'library' of templates between a Pylons app and Django app. I've hit a minor stumbling block in that Django's template context is accessible from the "top-level" of the template, whereas Pylons wraps your context inside the thread local c (or tmpl_context) variable. Here are some analogous examples that demonstrate this. Django from django.shortcuts import render_to_response ctx = {} ctx['name'] = 'John' return render_to_response('hello.html', ctx) hello.html: Hello {{ name }} Pylons from pylons import tmpl_context as c from myapp.lib.base import render c.name = 'John' return render('hello.html') hello.html: Hello {{ c.name }} What I'm trying to do is make it so that hello.html is the same across both frameworks. One way I see to do it is by wrapping the Django render_to_response and do something like this: ctx['c'] = ctx But that just doesn't feel right. Anybody see other alternatives to this? Thanks

  • Getting "Illegal Seek" error after calling accept()

    - by Bilthon
    Well.. it's pretty much that, I seem to be getting a "Illegal Seek" error when checking my errno variable. The problem is that I have no idea of what that can mean. I know sockets are treated like files in unix, but I can't see how can this be related to sockets. What I'm doing exactly is: int sck = ::accept(m_socket, (struct sockaddr*)&client_address, (socklen_t*)&address_len); Then I get sck = -1 and errno = ESPIPE And the weird thing is that it happens randomly. I mean, sometimes the code works fine, and sometimes it just thows an exception. I'm working with threads so that's understandable. But I just would like to know what kind of behaviour makes the accept() call to set errno as ESPIPE so I could check the paramethers for instance. Thanks Nelson R. Pérez

  • MATLAB fill area between lines

    - by dustynrobots
    I'm trying to do something similar to what's outlined in this post: MATLAB, Filling in the area between two sets of data, lines in one figure but running into a roadblock. I'm trying to shade the area of a graph that represents the mean +/- standard deviation. The variable definitions are a bit complicated but it boils down to this code, and when plotted without shading, I get the screenshot below: x = linspace(0, 100, 101)'; mean = torqueRnormMean(:,1); meanPlusSTD = torqueRnormMean(:,1) + torqueRnormStd(:,1); meanMinusSTD = torqueRnormMean(:,1) - torqueRnormStd(:,1); plot(x, mean, 'k', 'LineWidth', 2) plot(x, meanPlusSTD, 'k--') plot(x, meanMinusSTD, 'k--') But when I try to implement shading just on the lower half of the graph (between mean and meanMinusSTD) by adding the code below, I get a plot that looks like this: fill( [x fliplr(x)], [mean fliplr(meanMinusSTD)], 'y', 'LineStyle','--'); It's obviously not shading the correct area of the graph, and new near-horizontal lines are being created close to 0 that are messing with the shading. Any thoughts? I'm stumped.

  • AJAX response inside jqplot not working

    - by JuanGesino
    I'm trying to render data from an AJAX response as a bar chart with jqplot. To render this bar chart I use two variables: s1 which contains the numbers ex: s1 = [22,67,32,89] ticks which contains the name corresponding to a number inside s1 ex: ticks = ["Jack", "Mary", "Paul", "John"] So my AJAX returns two variables, data1 and data2. When I console.log(data1) I get 22,67,32,89 When I console.log(data2) I get "Jack", "Mary", "Paul", "John" I then add the square brackets and change variable: s1 = [data1] ticks = [data2] When I console.log(s1) I get ["22,67,32,89"] When I console.log(ticks) I get "Jack", "Mary", "Paul", "John" And the graph does not render, this is my code: s1 = [data]; ticks = [data]; plot4 = $.jqplot('chartdiv4', [s1], { animate: !$.jqplot.use_excanvas, series:[{color:'#5FAB78'}], seriesDefaults:{ renderer:$.jqplot.BarRenderer, pointLabels: { show: true } }, axes: { xaxis: { renderer: $.jqplot.CategoryAxisRenderer, ticks: ticks }, yaxis:{min:0, max:100, label:'%',labelRenderer: $.jqplot.CanvasAxisLabelRenderer} }, highlighter: { show: false } }); });

  • Loading html dynamically using Javascript and PHP

    - by Vafello
    I have the following code: <?php if ($x == 1){ ?> <b>Some html...</b> <?php } else if ($x==2){ ?> <b> Other html...</b> <?php } ?> Now I would like to have two links below (a href) and somehow pass the variable $x (so Link1 passes x=1 and Link2 passes x=2) in order to load the relevant bit of code from if statement. I know I can pass $x using form and then test its value and load required bit of code, but I would like to do it smoothly, without reloading the page. I think that JQuery could help it, but I have no idea how to do it. Any ideas greatly appreciated.

  • regular expression search in python

    - by Richard
    Hello all, I am trying to parse some data and just started reading up on regular Expressions so I am pretty new to it. This is the code I have so far String = "MEASUREMENT 3835 303 Oxygen: 235.78 Saturation: 90.51 Temperature: 24.41 DPhase: 33.07 BPhase: 29.56 RPhase: 0.00 BAmp: 368.57 BPot: 18.00 RAmp: 0.00 RawTem.: 68.21" String = String.strip('\t\x11\x13') String = String.split("Oxygen:") print String[1] String[1].lstrip print String[1] What I am trying to do is to do is remove the oxygen data (235.78) and put it in its own variable using an regular expression search. I realize that there should be an easy solution but I am trying to figure out how regular expressions work and they are making my head hurt. Thanks for any help Richard

  • Removing $_SESSION['layout']['action'] globally from all users!

    - by sologhost
    Ok, I am storing a session variable like so to load up users layouts faster if it's set instead of calling the database. But since the layout can be changed via the Administrator, I'd like to be able to globally remove all sessions where $_SESSION['layout']['action'] is set for all users. $_SESSION['layout']['action'] = array(a ton of indexes and mulit-dimensional arrays); Now, I know it's being stored into my database sessions table, there's a column for session_id, last_update, and data. So, question I have is how to remove that session array key ['action'] from all users. Using $_SESSION = array(); session_destroy(); Does not work. Basically, session_start() is being loaded on every page load, so I just want to remove all ['action'] keys from ['layout']. Is this possible to do? Thanks

  • Need a formula for calculating the tax portion of a total amount.

    - by pawz
    In Australia we have to advertise products with tax already added, so rather than say a product is $10 + $1 GST = $11, we normally work backwards and say "ok, total is $10, how much of that is GST ?" For example, for a $10 total, you do 10 * (1 /11) = 0.91, which is the tax component of the $10 total. My problem is I need calculate a formula for working out the taxable component when the tax rate is a variable. So far I've made this calculation although I'm not sure how correct an assertion it is: 10 * (1 / x) = 0.09 * (1 / y) where y = 10, x = 11 Basically i want to work out x on the left hand side when I know that the tax rate is 0.05 for example, which will give me a formula that I can use to calculate the taxable component of an total figure. I want a function into which I can plug in the total price and the tax rate, and get back the taxable component of the total price. I'd really appreciate the help with this as it really makes my head hurt ! :")

  • java - volatile keyword

    - by Tiyoal
    Say I have two threads and an object. One thread assigns the object: public void assign(MyObject o) { myObject = o; } Another thread uses the object: public void use() { myObject.use(); } Does the variable myObject have to be declared as volatile? I am trying to understand when to use volatile and when not, and this is puzzling me. Is it possible that the second thread keeps a reference to an old object in its local memory cache? If not, why not? Thanks a lot.

  • How do I change the zone offset for a time in ruby?

    - by Janak
    I have a variable foo that contains a time, lets say 4pm today, but the zone offset is wrong, i.e. it is in the wrong time zone. How do I change the time zone? When I print it I get Fri Jun 26 07:00:00 UTC 2009 So there is no offset, and I would like to set the offset to -4 or Eastern Standard Time. I would expect to be able to just set the offset as a property of the Time object, but that doesn't seem to be available?

  • jquery - loose click() event after ajax call ???

    - by niczoom
    At the following webpage liamharding.com/pgi.php I have an option panel on the left side of the page which opens and close's upon clicking the panels 'arrow', this works fine until you select a market (for testing use one of the 'Random Walk' markets and click 'Show/Refesh Graphs'), this then makes an ajax call using get_graph(forexName, myCount, divIsNew) function. Once this call is completed a graph(s) is displayed and then my options panels click() event does not work? The ajax call returns the data in a variable ajax_data, the problem happens when I perform the following code var jq_ajax_data = $("<div/>").html(ajax_data); . I need to wrap it in a so I can extract data from it using jQuery. If this line of code is commented out the click() event works fine ?? Hope somebody can help, I have spent a lot of time but cant find what the problem is.

  • Objective-C: Protocols

    - by Stu
    I'd like an instance variable object to adopt a protocol. @interface GameScene : Scene <AVAudioPlayerDelegate> { @private Layer *content <CocosNodeOpacity>; } For example I'd like my Layer object to adopt the <CocosNodeOpacity> so that I can get the methods -(GLubyte) opacity; //and -(void) setOpacity: (GLubyte) opacity; for free. The syntax shown above is invalid. Is it possible to achieve this without creating a new implementation file and creating a custom object? Thanks.

  • Setting variables in web config for web service consumption

    - by Evan
    I did a couple google searches about this and am not finding anything, so I thought I'd ask here. I'm working on our internal CMS and I noticed that we're getting live data back when doing debugging because of our web services instead of the dev data that I wanted. It doesn't do this on our dev CMS website, but we're trying to do all our development on localhost. Is there any way to set up an environment variable in our web config for the URL so that the CMS points to the dev database instead of live database that is referenced in the wsdl files?

  • Search object array for matching possible multiple values using different comparison operators

    - by Sparkles
    I have a function to search an array of objects for a matching value using the eq operator, like so: sub find { my ( $self, %params ) = @_; my @entries = @{ $self->{_entries} }; if ( $params{filename} ) { @entries = grep { $_->filename eq $params{filename} } @entries; } if ( $params{date} ) { @entries = grep { $_->date eq $params{date} } @entries; } if ( $params{title} ) { @entries = grep { $_->title eq $params{title} } @entries; } .... I wanted to also be able to pass in a qr quoted variable to use in the comparison instead but the only way I can think of separating the comparisons is using an if/else block, like so: if (lc ref($params{whatever}) eq 'regexp') { #use =~ } else { #use eq } Is there a shorter way of doing it? Because of reasons beyond my control I'm using Perl 5.8.8 so I can't use the smart match operator. TIA

  • Server 2008, 2 NICs, 2 fixed IPs - big delays using internet

    - by user46055
    Hi geniuses I have an all in one Windows 2008 server, configured with AD/DHCP/DNS/RRAS - all set up with wizards and no specific tweaking. The server has 2 network adapters : one of which ("MyWAN") is plugged into our office's internet connection, the other ("MyLAN") is plugged into a local switch, which is also where all our desktops are connected. So this one server is doing everything. When first set up, MyLAN had a fixed IP of 192.168.2.1 and served the desktops with DHCP scope 192.168.2.50-99. It also told them to use 192.168.2.1 as DNS and gateway. MyWAN was setup to take its IP etc from DHCP, being handled by the building's router and ADSL modem etc. All desktops were setup to use DHCP. This all worked perfectly fine, until I recently changed MyWAN to have a static IP (I wanted to access it from home, and needed to give it a static IP to port map in the building's router). Things still work, but there is now a long delay when accessing the internet. The actual speed is as before when downloading, but there is a pause of 3-6 secs when connecting to new hosts (for example if I browse to slashdot from either a desktop or the server itself, it'll hang on connecting to slashdot.org, hang again on connecting to *.fsdn, *.google-analytics.com and all the other hosts referenced from the main page). If I ping slashdot.org from the server, I get the following : Pinging slashdot.org [216.34.181.45] with 32 bytes of data: Reply from 192.168.2.1: Destination host unreachable. Reply from 216.34.181.45: bytes=32 time=99ms TTL=239 Reply from 216.34.181.45: bytes=32 time=100ms TTL=239 Reply from 216.34.181.45: bytes=32 time=101ms TTL=239 Pinging anywhere external always seems to hit 192.168.2.1 first, which doesn't seem right. Trying tracert from the server gives the following : Tracing route to slashdot.org [216.34.181.45] over a maximum of 30 hops: 1 MYSERVER01.intranet [192.168.2.1] reports: Destination host unreachable Trying tracert from a desktop gives the following : Tracing route to slashdot.org [216.34.181.45] over a maximum of 30 hops: 1 <1 ms * <1 ms MYSERVER [192.168.2.1] 2 * * * Request timed out. 3 6 ms 6 ms 6 ms dsl-gw1.ge.mer.uk.webtapestry.net [217.151.111.17] 4 38 ms 239 ms 251 ms gw-router.ge.mer.uk.webtapestry.net [217.151.111.13] ...and then all is fine after that. I think that DNS is working fine because the domain names are getting translated to correct IPs immediately. DHCP seems to be okay? So perhaps it's something up with my RRAS setup - although I can't see any option during the setup wizard which I would have filled in differently. I've also tried changing the binding order of the two network connections, to prioritise MyWAN, but that doesn't seem to have done anything. Any idea what's up? Many thanks - Rob

  • 'Array of arrays' in matlab?

    - by waitinforatrain
    Hey, having a wee bit of trouble. Trying to assign a variable length 1d array to different values of an array, e.g. a(1) = [1, 0.13,0.52,0.3]; a(2) = [1, 0, .268]; However, I get the error: ??? In an assignment A(I) = B, the number of elements in B and I must be the same. Error in ==> lab2 at 15 a(1) = [1, 0.13,0.52,0.3]; I presume this means that it's expecting a scalar value instead of an array. Does anybody know how to assign the array to this value? I'd rather not define it directly as a 2d array as it is for are doing solutions to different problems in a loop Edit: Got it! a(1,1:4) = [1, 0.13,0.52,0.3]; a(2,1:3) = [1, 0, .268];

  • Objective-C "if" statements not retaining

    - by seanny94
    I know the title of this question is a bit confusing, but here it goes anyway: I'm creating an NSString after an if statement but it just doesn't seem to want to retain outside of the statement. My conditional looks like this: if ([[password stringValue] isEqualToString:@""]) { NSString *pwd = [[NSString alloc]initWithString:@"password"]; } else { NSString *pwd = [[NSString alloc]initWithFormat:@"%@", [password stringValue]]; } ... and I call pwd later in the script like this: NSArray *arguments; arguments = [NSArray arrayWithObjects: ip, pwd, nil]; [task setArguments: arguments]; But when I do so in this way, the first snippet returns a warning of Unused variable 'pwd' and the latter call ends up in an error of 'pwd' undeclared. What am I doing wrong here? Thanks in advance. ;)

  • Adding additional components to a web page after rendering by Wicket

    - by Andrew Fielden
    I have a requirement to create a web page using Wicket 1.5, which can present a variable number of panels to capture user input. All the panels have the same structure. The page would start off with one panel, and includes a button to dynamically add more as required. So the number of panels is unknown at the time the page is initially rendered. Effectively I'd be altering the structure of the page dynamically. This is possible in Javascript, using document.addElement() I've done a similar thing in the past by creating all the components on page load, and selectively showing/hiding components. The difference here is that the number of components (panels) is initially unknown. I'm unsure as to how this would be achieved with Wicket.
