  • Cocos2D Command-Line Application

    - by Hasyimi Bahrudin
    Is it possible to create a terminal application which uses cocos2d? I've tried to make one using cocos2d 2.x, but it requires a MacGLView to be initialized. I need it so that I could program a terminal application that generates a screenshot given a TMX file and an optional preferred width or height parameter (for resizing). Then I can automate the generation of map previews for my game, instead of manually taking screenshots. It's not practical to load the actual TMX and resize it inside the game (what I'm currently doing), because each TMX file has 7 layers, my tile sheet is huge, and I have lots of levels.

  • Icons don't display for some application launchers

    - by Smk
    I am running Ubuntu 12.04 on my laptop for some time now. Since the first day only I have been facing the problem with icon images of some application not appearing up. It causes a lot of inconvenience in locating/identifying an application to be launched. I have updated my Ubuntu with the latest build today only but still the problem persists. I have googled around and tried everything relevant available out there but with no success. Please note that reinstalling Ubuntu is NOT an option right now.

  • ViewController behaving oddly when pushed on the window

    - by ayazalavi
    I am using multiple controller during launch of an application in app delegate. One controller is for registration and the second controller is tabbar. tabbar was loading fine but when I pushed registration controller on window, contents went up by 20 units and I have good white blank screen at bottom. Therefore I recreated frame of my registration view controller in its viewdidload method and slided it 20 units down. The code is self.view.frame = CGRectMake(0, 20, self.view.frame.size.width, self.view.frame.size.height); and code in my app delegate for launch application was - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if (![self accountExists]) { //code if account does not exists on iphone app database self.registerAccount = [[registerViewController alloc] initWithNibName:@"registerViewController" bundle:nil]; [window addSubview:registerAccount.view]; } else if([self autoLoginForAnyAccount]){ //code for autologin to app } else { self.tabBarController.selectedIndex = 1; self.tabBarController.delegate = self; [window addSubview:tabBarController.view]; } [window makeKeyAndVisible]; return YES; } if anyone knows why there is a white space at bottom when registration controller is pushed then please share it with me.

  • Creating a Application in Winrt that requires Internet

    - by wtsang02
    I am making a paid App for Windows 8, c#. I am wondering which is better? If my application doesn't need internet connection normally but does requires internet connection for the first time to download content data. --Makes my life easier Load the default data when installing. Then ask the user if he wants to update in app. -- Making the default data will be pain. Now my big question is, is it safe to assume user has access to internet now-a-days when using application that shouldn't require internet?

  • Application versioning

    - by Mathew
    Haven't find similar issue so sorry if thats a duplicate. I'm about to start a migration of an already existing project from one web container version to the another. Currently, the application version is 2.2.5. Business requirement is to deliver a 3.0 version by the end of the year. Additional constraint is to release a working, stable version by the end of Q3. We are about to work in 2-weeks sprints and I'm wondering how can I approach the problem? I was thinking about releasing 2.3 by the end of Q2, then immediately promoting it as 3.0-a1, work on alphas (3.0-a2, 3.0-a3, ...) till the end of Q3, to start with 3.0-b1 in the early Q4 and finally release 3.0 around December. I don't feel comfortable saying that the application is already in 3.0 state in July, but I can't see other options. If you find some book chapters/blogs or your personal experience interesting please share your opinion.

  • Task-It Webinar - Building a real-world application with RadControls for Silverlight 4

    Yesterday I held a live webinar on Building a real-world application with RadControls for Silverlight 4. Thank you to all of those that attended, but if you did not have a chance to catch it, you can watch a recorded version here: Building a real-world application with RadControls for Silverlight 4 I wasn't able to get too deep into the inner workings of the app because of time limitations, but over the upcoming weeks I will dig deeper in my blog posts, and potentially some videos. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Problems with binding to Window Height and Width

    - by D.H.
    I have some problems when I try to bind the height and width of a window to properties in my view model. Here is a small sample app to illustrate the problem. This is the code in app.xaml.xs public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); MainWindow mainWindow = new MainWindow(); MainWindowViewModel mainWindowViewModel = new MainWindowViewModel(); mainWindow.DataContext = mainWindowViewModel; mainWindow.Show(); } } This is MainWindow.xaml: <Window x:Class="TestApp.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="{Binding WindowHeight}" Width="{Binding WindowWidth}" BorderThickness="{Binding WindowBorderThickness}"> </Window> And this is the view model: public class MainWindowViewModel { public int WindowWidth { get { return 100; } } public int WindowHeight { get { return 200; } } public int WindowBorderThickness { get { return 8; } } } When the program is started the getters of WindowHeight and WindowBorderThickness (but not WindowWidth) are called, so the height and the border of the window is set properly, but not the width. I then add button that will trigger PropertyChanged for all properties, so that the view model now looks like this: public class MainWindowViewModel : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public void TriggerPropertyChanges() { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs("WindowWidth")); PropertyChanged(this, new PropertyChangedEventArgs("WindowHeight")); PropertyChanged(this, new PropertyChangedEventArgs("WindowBorderThickness")); } } public ICommand ButtonCommand { get { return new RelayCommand(delegate { TriggerPropertyChanges(); }); } } public int WindowWidth { get { return 100; } } public int WindowHeight { get { return 200; } } public int WindowBorderThickness { get { return 8; } } } Now, when I click the button, the getter of WindowBorderThickness is called, but not the ones for WindowWidth and WindowHeight. It all just seems very weird and inconsistent to me. What am I missing?

  • xubuntu keyboard application shortcuts not working

    - by Guanidene
    I am using the latest Xubuntu 13.04 with Xfce 4.10. I have issues while setting "Application Shortucts' from 'Settings Manager Keyboard Application Shortcuts'. Not all custom keyboards shortcuts, which I have added, work. Some do, some don't. Example the command 'xdotool key XF86AudioPause' works perfect from cmdline, but not when I assign this as a shortcut to some key, say 'F11'. Have tried to Google about this, but found nothing. Kindly help. If possible, kindly provide me a cmdline way to set a keyboard shortcut

  • What type of application is this called?

    - by boatingcow
    I am working on a web-based application which combines elements of what my client would call a CMS (content management system) and CRM (customer relations management) but also adds in many other business-specific features such as bookings management, staff task allocation management, wages calculations, document version control etc. However, I'm struggling to find a catch-all term for this type of application so I can research how other people have gone about creating such an integrated solution. Can anyone recommend a term I can use to refer to this, both internally in our team, for the client so they know what to call the 'system' and also for me personally, so that I can ask the Stack community further questions?

  • Why don't windows of the same application behave as they should in Oneiric?

    - by Yuttadhammo
    Somewhere along the upgrade path, Unity has developed some strange logic behind window layering. First, before Oneiric, there was a way to see all the windows of an application - I think it was when you click on the icon in the launcher. Now, clicking on the icon often does nothing. Suppose I have two terminals open, one behind this Firefox window, and one in front of it. Clicking on the launcher does nothing - the only way to find the second terminal, afaics, is to move the Firefox window or use the task switcher (which has a whole slew of problems of its own). Secondly, once I have both terminals on top, then I decide to close one of them, suddenly they both disappear (the second one, for some reason, has gone into hiding behind the Firefox window). Third (though I can't pin it down now), sometimes when a window is on top, focus is still on a window in back; I click on the top x to close the window in front, only to find I've closed an important window in the back. I can't really believe these are bugs, since they seem too obvious to not have been fixed by now. My question is, am I missing something? Some compiz option I can set to make it act like it used to? Or is this really how Unity is supposed to act?

  • Multiple Windows Desktop areas for Full-Screen applications

    - by arootbeer
    Is it possible to run multiple instances of Windows Explorer within a single user session, or configure multiple desktops that are portions of a screen? I don't know the best way to describe what I want to achieve, but here's a picture of what I've got: I've got a 4 monitor setup, 3 portrait and one landscape, and I am normally running a number of RDP sessions, outlook, chrome, a development environment or two, so on and so forth. Most of these applications support full-screen views which mostly or completely hide the window borders, but on the Windows Desktop they take up a full monitor to do so. What I want to do is have 7 "desktops", "regions", call them what you will, each of which is, for the purposes of applications running in it, a "full screen" environment: I'm not tied to Windows Explorer for this, in case it helps - a different window manager that will support this functionality would be a perfectly acceptable answer.

  • Pass variable to Info Window in FusionTableLayer

    - by user1030205
    I am building a web application that includes a Google Map layered with data from a Google Fusion Table. I have defined the info window for the markers in the Fusion Table and all is rendering as expected, but I have one issue. I need to pass a session variable from my web application to be included in the links that are defined in the info window, but can't seem to find a way to do this. Below is the javascript I am currently using to render the map: var myOptions = { zoom: 10, mapTypeId: google.maps.MapTypeId.ROADMAP, center: new google.maps.LatLng( 40.4230,-98.7372) } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); // Weather weatherLayer = new google.maps.weather.WeatherLayer({ temperatureUnits: google.maps.weather.TemperatureUnit.FAHRENHEIT }); weatherLayer.setMap(map); //Hobby Stores var storeLayer = new google.maps.FusionTablesLayer({ query: { select: "col2", from: "3991553" }, map: map, supressInfoWindows: true }); //Club Sites var siteLayer = new google.maps.FusionTablesLayer({ query: { select: "col13", from: "3855088" }, styles: [{ markerOptions: { iconName: "airports" }}], map: map, supressInfoWindows: true }); I'd like to be able to pass some type of parameter in the call to google.maps.FusionTableLayer that passes a value to be include in the info window, but can't find a way to do this. To view the actual page, visit www.dualrates.com. Enter your zipcode and select one of the airport markers to see the info window. You may have to zoom the map out to see an airfield.

  • Changing window focus on OS X

    - by MatsT
    As part of an InstallationCheck script on OS X I need to use finder dialogs to let the user browse for files. When I'm done I want to move the installer application up front again so that the user can easily continue with the installation. I have already tried the simple: tell application "Installer" to activate This does not work because as long as I am inside the script the Installer application is unresponsive and when i try to activate it the applescript will try to wait until Installer responds, effectively locking the program until the InstallationCheck script times out. So basically I need a way to focus an application that works even if it is currently unresponsive. Is there any way to do this either from an applescript or directly from the perl script?

  • Application stuck in TCP retransmit

    - by SandeepJ
    I am running Linux kernel 3.13 (Ubuntu 14.04) on two Virtual Machines each of which operates inside two different servers running ESXi 5.1. There is a zeromq client-server application running between the two VMs. After running for about 10-30 minutes, this application consistently hangs due to inability to retransmit a lost packet. When I run the same setup over Ubuntu 12.04 (Linux 3.11), the application never fails If you notice below, "ss" (socket statistics) shows 1 packet lost, sk_wmem_queued of 14110 (i.e. w14110) and a high rto (120000). State Recv-Q Send-Q Local Address:Port Peer Address:Port ESTAB 0 12350 192.168.2.122:41808 192.168.2.172:55550 timer:(on,16sec,10) uid:1000 ino:35042 sk:ffff880035bcb100 <- skmem:(r0,rb648720,t0,tb1164800,f2274,w14110,o0,bl0) ts sack cubic wscale:7,7 rto:120000 rtt:7.5/3 ato:40 mss:8948 cwnd:1 ssthresh:21 send 9.5Mbps unacked:1 retrans:1/10 lost:1 rcv_rtt:1476 rcv_space:37621 Since this has happened so consistently, I was able to capture the TCP log in wireshark. I found that the packet which is lost does get retransmitted and even acknowledged by the TCP in the other OS (the sequence number is seen in the ACK), but the sender doesn't seem to understand this ACK and continues retransmitting. MTU is 9000 on both virtual machines and througout the route. The packets being sent are large in size. As I said earlier, this does not happen on Ubuntu 12.04 (kernel 3.11). So I did a diff on the TCP config options (seen via "sysctl -a |grep tcp ") between 14.04 and 12.04 and found the following differences. I also noticed that net.ipv4.tcp_mtu_probing=0 in both configurations. Left side is 3.11, right side is 3.13 <<net.ipv4.tcp_abc = 0 <<net.ipv4.tcp_cookie_size = 0 <<net.ipv4.tcp_dma_copybreak = 4096 14c11 << net.ipv4.tcp_early_retrans = 2 --- >> net.ipv4.tcp_early_retrans = 3 17c14 << net.ipv4.tcp_fastopen = 0 >> net.ipv4.tcp_fastopen = 1 20d16 << net.ipv4.tcp_frto_response = 0 26,27c22 << net.ipv4.tcp_max_orphans = 16384 << net.ipv4.tcp_max_ssthresh = 0 >> net.ipv4.tcp_max_orphans = 4096 29,30c24,25 << net.ipv4.tcp_max_tw_buckets = 16384 << net.ipv4.tcp_mem = 94377 125837 188754 >> net.ipv4.tcp_max_tw_buckets = 4096 >> net.ipv4.tcp_mem = 23352 31138 46704 34a30 >> net.ipv4.tcp_notsent_lowat = -1 My question to the networking experts on this forum : Are there any other debugging tools or options I can install/enable to dig further into why this TCP retransmit failure is occurring so consistently ? Are there any configuration changes which might account for this weird behaviour.
