  • iPhone UIScrollView embedded UIView is clipped

    - by scc
    Hello. I have an iPad UIView subclass (we'll call LargerUIView) with which I do a bunch of drawing via drawRect: once asked. That all appears to be working, and looks the way I like. I'm at the point now of trying to get scrolling working (just in the horizontal to begin), yet when I try to scroll, what shows below is black (ie, appears to have never been drawn). That doesn't surprise me as it's likely been clipped. Looking for suggestions. Here's what I'm doing so far: MyAppDelegate.m - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { CGRect scrollRect = CGRectMake(0, 0, 768, 1024); UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:scrollRect]; LargerUIView *view = (LargerUIView *)[viewController view]; [scrollView addSubview:view]; [scrollView setContentSize:CGSizeMake(768, pageHeight)]; [scrollView setContentMode:UIViewContentModeRedraw]; [scrollView setClipsToBounds:YES]; [window addSubview:scrollView]; [scrollView release]; // Without this next line, the "frontmost" (ie, most recently added subview) // is the MoxiesAppetizerMenu - which is not equipped to handle scrolling/UIEvents [window sendSubviewToBack:view]; // Show it all. [window makeKeyAndVisible]; return YES; } Any suggestions? Have tried changing "setClipsToBounds" to NO as well.

  • jquery ui dialog and our dearest friend, ie6

    - by bradjive
    I'm using the jquery ui dialog for a modal popup dialog. It's working great in Firefox/Chrome but terrible in ie6. Problem: When I show the dialog in ie6, the browser window grows and automatically scrolls down to the bottom. The height increase and automatic scroll-down is equal to the height of the jquery dialog. I can scroll up and then use the dialog as normal, but the behavior where it grows the window and drops is maddeningly unacceptable. Here is how I'm launching the window: <div id="dialogWindow"></div> ... $(document).ready(function() { var $dialog = $("#dialogWindow").dialog({ autoOpen: false, modal: true, minWidth: 560, width: 560, resizable: "true", position: "top" }); $('.addButton').click(function(e) { e.preventDefault(); $('#dialogWindow').load('http://myurl'); $dialog.dialog('open'); }); }); I am already using the bgiframe plugin for jquery which is key for ie6 overlay issues. But this seems unrelated to that. Has anyone seen this before and found a work around?

  • Sharepoint Site Administration

    - by Shrewd Demon
    Hey, I've got a SharePoint website running on my machine (which it shows me inside the Application Pool in the Inet Manager). Now this website has a different user credentials specified under the Identity section (properties). Also when I view the w3wp.exe in the task manager it shows that the site is running as a different user. The problem is that if I change the username and password of the existing user with mine, the site stops working. How do I run it under my account credentials. Please help. Thanks

  • SSL connection using Java standalone app

    - by Marquinio
    I have created a standalone executable JAR program that needs to send private information over a SSL connection. I was not able to establish the SSL connection using certificates. Was getting this: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path `building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target` So I found some code somewhere that creates a trust manager that does not validate certificate chains: // Create a trust manager that does not validate certificate chains TrustManager[] trustAllCerts = new TrustManager[]{ new X509TrustManager() { public java.security.cert.X509Certificate[] getAcceptedIssuers() { return null; } public void checkClientTrusted( java.security.cert.X509Certificate[] certs, String authType) { } public void checkServerTrusted( java.security.cert.X509Certificate[] certs, String authType) { } } }; That did the trick and I was able to establish SSL connection without any certificates. My concern is if the data will still be encrypted when exchanging private information. This is an execute JAR file that clients will be downloading to their computers. So is a certificate really necessary for this case? Thanks.

  • UIView Login screen to tabbar logic

    - by Benjamin De Bos
    Folks, i'm having trouble with some navigation logic. Currently i have a simple two tabbed tabbar application. But i want to show a loginscreen in front. So that would be an UIView. Currently the code is as follows: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; UIViewController *viewController1 = [[roosterViewController alloc] initWithNibName:@"roosterViewController" bundle:nil]; UIViewController *viewController2 = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; self.tabBarController = [[UITabBarController alloc] init]; self.tabBarController.viewControllers = @[viewController1, viewController2]; self.window.rootViewController = self.tabBarController; [self.window makeKeyAndVisible]; return YES; } SO this pushes a simple tabcontroller. Well, now i want to have a login screen. So that would be a simple UIView which pushes the tabbar controller. But i can't seem to see the logic on how to do this. I've been trying to present a modal view controller, but the thing is: the tabbar will be loaded on the background. Since i need the username/password information to work on the tabbarview, this won't work. My Logic would be: delegate load loginViewController load tabbar controller But, then i need to be able to "logout". So i need to destroy the tabbar controller and present the login screen. Any thoughts on this?

  • hg access control to central repository

    - by andreas buykx
    We come from a subversion background where we have a QA manager who gives commit rights to the central repository once he has verified that all QC activities have been done. Me and a couple of colleagues are starting to use mercurial, and we want to have a shared repository that would contain our QC-ed changes. Each of the developers hg clones the repository and pushes his changes back to the shared repository. I've read the HG init tutorial and skimmed through the red bean book, but could not find how to control who is allowed to push changes to the shared repository. How would our existing model of QA-manager controlled commits translate to a mercurial 'central' repository?

  • GetDiskFreeSpaceEx reports wrong number of free bytes

    - by rboorgapally
    __int64 i64FreeBytes unsigned __int64 lpFreeBytesAvailableToCaller, lpTotalNumberOfBytes, lpTotalNumberOfFreeBytes; // variables used to obtain // the free space on the drive GetDiskFreeSpaceEx (Manager.capDir, (PULARGE_INTEGER)&lpFreeBytesAvailableToCaller, (PULARGE_INTEGER)&lpTotalNumberOfBytes, (PULARGE_INTEGER)&lpTotalNumberOfFreeBytes); i64FreeBytes = lpTotalNumberOfFreeBytes; _tprintf(_T ("Number of bytes free on the drive:%I64u \n"), lpTotalNumberOfFreeBytes); I am working on a data management routine which is a Windows CE command line application. The above code shows how I get the number of free bytes on a particular drive which contains the folder Manager.capdir (it is the variable containing the full path name of the directory). My question is, the number of free bytes reported by the above code (the _tprintf statement) doesn't match with the number of free bytes of the drive (which i check by doing a right click on the drive). I wish to know if the reason for this difference?

  • WPF EventRouting to Children

    - by Shaun Bowe
    Is there any way to broadcast a RoutedEvent to all of my children in WPF? For example lets say I have a Window that has 4 children. 2 of them know about the RoutedEvent 'DisplayYourself' and are listening for it. How can I raise this event from the window and have it sent to all children? I looked at RoutingStrategy and Bubble is the wrong direction, Tunnel and Direct don't work because I don't know which children I want to send this to. I just want to broadcast this message and have whoever cares about it handle it. update: I declared the events in a static class. public static class StaticEventClass { public static readonly RoutedEvent ClickEvent = EventManager.RegisterRoutedEvent("Click", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(StaticEventClass)); public static readonly RoutedEvent DrawEvent = EventManager.RegisterRoutedEvent("Draw", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(StaticEventClass)); } The problem is when I raise the event from my window, the children never see it. RoutedEventArgs args = new RoutedEventArgs(StaticEventClass.DrawEvent, this); this.RaiseEvent(args); update again.. Here is the handler in the child. public ChildClass() { this.AddHandler(StaticEventClass.DrawEvent, new RoutedEventHandler(ChildClass_Draw)); }

  • Redirect parent of a page from a cfwindow

    - by Ryan French
    Hi All, I have a page with cfwindow that require the user to be logged in to view the content on the page. The problem at the moment is if the user logs into the site, then does nothing and the session times out, I have no way that I can think of to redirect the parent of the window to the login screen when the user opens it. So far I have tried using cflocation but that has no way of specifying the container that should be redirected (i.e. the page in the window is being redirected but not the windows parent). I have also thought about using a hidden input with a value based on the session which is then check with Body onLoad event but currently this doesnt work with how the pages have been setup. The last option I have is to check the session variable on loading the window and then closing it if the user is not logged in, which will cause the parent to refresh and redirect to login anyway. However I cant find a way to close a cfwindow without using javascript. Thanks for any help you can give.

  • Dependency Property ListBox

    - by developer
    Hi All, I want to use a dependency property, so that my label displays values selected in the listbox. This is just to more clearly understand the working of a dependency property. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:WPFToolkit="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" xmlns:local="clr-namespace:WpfApplication1" x:Name="MyWindow" Height="200" Width="300" > <StackPanel> <ListBox x:Name="lbColor" Width="248" Height="56" ItemsSource="{Binding TestColor}"/> <StackPanel> <Label Content="{Binding Path=Test, ElementName=lbColor}" /> </StackPanel> </StackPanel> </Window> Code Behind, namespace WpfApplication1 { /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window { public ObservableCollection<string> TestColor { get; set; } public String Test { get { return (String)GetValue(TestProperty); } set { SetValue(TestProperty, value); } } // Using a DependencyProperty as the backing store for Title. This enables animation, styling, binding, etc... public static readonly DependencyProperty TestProperty = DependencyProperty.Register("Test", typeof(String), typeof(ListBox), new UIPropertyMetadata("Test1")); public Window1() { InitializeComponent(); TestColor = new ObservableCollection<string>(); DataContext = this; TestColor.Add("Red"); TestColor.Add("Orange"); TestColor.Add("Yellow"); TestColor.Add("Green"); TestColor.Add("Blue"); } } } Can anyone explain me how will I accompalish this using a dependency property. Somehow I am very confused with the Dependency Property concept, and I just wanted to see a working example for that.

  • How do I search for a string with quotes?

  • Reporting services genius only: a fast way to get Reporting Services local site working?

    - by Junior Mayhé
    Hello I was here trying to figure out why my Reports manager is empty, there's no tabs at all. I installed SQL Server 2008 complete, but didn't not configure Reporting Services. When installing SQL Server 2008, this Windows 7 version didn't have yet IIS installed, I installed it later. I don't see where is this localhost/Reports physically on my Hard Drive, where is the physic folder? I don't see on IIS where is Report folder, would it exist? The site settings people talk about, I can't find it. The "Reporting Services" service is running on automatic at SQL Server Configuration Manager. How can I get Reporting Services this working without struggling? (I can't see why is necessary to customize all these user permissions)

  • How to make Web Storage persistent in Cordova using JS?

    - by ett
    I have a small quiz app, which is a cross-platform mobile app, that I plan for it to run on Android, iOS, and WP8. I want to store a local highscore, where it will keep track how many points the user had, and if he/she does better than the already stored highscore, update the current highscore. Though, I want the highscore to be persistent, what I mean is, every time the user opens the app I want the last highscore to be present and it to be compared with the new quiz score. Meaning, I don't want the highscore to be deleted after each time the app is closed. I also want for the first time when the app is ran, the highscore to be set to 0, so obviously the first time the user finishes the quiz gets a new highscore. I have those codes so far: scoredb.js // Wait for device API libraries to load document.addEventListener("deviceready", initScoreDB, false); // Device APIs are available function initScoreDB() { window.localStorage.setItem("score", 0); highscore = window.localStorage.getItem("score"); } main.js var correct = 0; var highscore; // In between I have some code that keeps incrementing // correct variable for each correct answer. if (correct > highscore) { window.localStorage.setItem("score", correct); highscore = correct; } It does seem to work okay once the app is started. I did the quiz three times, in the simulator, and it keeps the score as it should. Though, each time I open the app, highscore is reseted to 0. I guess it is due to the fact that I call initScoreDB when the device is ready, and I initialize the score to 0 there and give that value to highscore. Can someone help me to initialize the score to 0 only when the app is ran for the first time, and all the other times to keep the latest highscore as the current highscore and compare it each time with the score that is achieved when the quiz is finished. If someone can help me, I would be glad.

  • Question about Linux Device Drivers.

    - by smwikipedia
    I have just installed the Xubuntu. My box runs quite slower than before when installed with a Win7. I am wondering if I am missing some device drivers. I can use gnome-device-manager to list my devices. In the device list view, I saw several blue question mark on the left side of devices. Based on my windows experience, the question mark should indicate the device is not properly configured. Is it the same with gnome-device-manager? And most importantly, how could I know for sure whether or not the corresponding device drivers have been installed? Many thanks.

  • Validation L2S question

    - by user158020
    This may be a bit winded because I am new to wpf. I have created a partial class for an entity in my L2S class that is primarily used for validation. It implements the onchanging and onvalidate methods. I am trying to use the MVVM pattern, and in a window/view I have set the datacontext in the xaml: <Window.DataContext> <vm:StartViewModel /> </Window.DataContext> when a user leaves a required field in the view blank, the onchanging event of the partial class is fired when I close the form, not when I save the data. So, if a user leaves the textbox blank, the old value is retained and the onchaging method is fired, but I have no idea how to alert the user of the resulting error. here is my onchanging code in the partial class: partial void Ondocument_titleChanging(string value) { if (value.Length == 0) throw new Exception("Document title is required."); if (value.Length > 256) throw new Exception("Document title cannot be longer than 256 characters."); } throwing an exception doesn't notify the user of the error. it just allows the form to close and rejects the changes to the textbox. hope this makes sense... edit: this example was taken from Scott Guthries article here: http://aspalliance.com/1427_LINQ_to_SQL_Part_5__Binding_UI_using_the_ASPLinqDataSource_Control.5

  • internet explorer 7 iframe unloads when going back

    - by André
    Hi this is my first post here, so please be kind ;-) i'm implementing a browser history manager, just like rsh or yui browser history manager. The idea was not to constantly poll the url hash of a hidden iframe, but to capture the onscroll event of an iframe, when it scrolls to an anchor name on an urlhashchange. So on every click i add an new anchor to iframe and set the iframe's hash to the anchors name. When pressing the back or forward button the frame scrolls to the previous or next anchor and the onscroll event is fired. That works great on firefox 3.0+, IE6 and Opera but on IE7 when hiting the back button the frame unloads and loses all its anchors. If anyone has an idea why this is happening or even a fix for this "bug", please i'm slowly going insane over this. thanks in advance btw the onscroll idea comes from: http://www.zachleat.com/web/2008/08/21/onhashchange-without-setinterval/

  • JAAS tutorial - how to force application to run with policy

    - by wuntee
    I just went through this tutorial: http://java.sun.com/docs/books/tutorial/security/tour2/index.html And was curios about the basic concept of JAAS... If every applcation needs to be run with the '-Djava.security.manager -Djava.security.policy=...' flags, what is enforcing security? Is it up to the end user to know when any Java application is being run, and modify the executable/script/whatever to include those flags? Or, how does a developer enforce that an application is run with the security manager enabled? The whole concept doesnt seem very functional to me - as it is by default not enabled... Am I missing something?

  • [Cocoa] Core Animation with an NSView and subviews

    - by ndg
    I've subclassed NSView to create a 'container' view (which I've called TRTransitionView) which is being used to house two subviews. At the click of a button, I want to transition one subview out of the parent view and transition the other in, using the Core Animation transition type: kCATransitionPush. For the most part, I have this working as you'd expect (here's a basic test project I threw together). The issue I'm seeing relates to resizing my window and then toggling between my two views. After resizing a window, my subviews will appear at seemingly random locations within my TRTransitionView. Additionally, it appears as if the TRTransitionView hasn't stretched correctly and is clipping the contents of its subviews. Ideally, I would like subviews anchored to the top-left of their parent view at all times, and to also grow to expand the size of the parent view. The second issue relates to an NSTableView I've placed in my first subview. When my window is resized, and my TRTransitionView resizes to match its new dimensions, my TableView seems to resize its content quite awkwardly (the entire table seems to jolt around) and the newly expanded space that the table now occupies seems to 'flash' (as if in the process of being animated). Extremely difficult to describe, but is there any way to stop this? Here's my TRTransitionView class: -(void) awakeFromNib { [self setWantsLayer:YES]; [self addSubview:[self currentView]]; transition = [CATransition animation]; [transition setType:kCATransitionPush]; [transition setSubtype:kCATransitionFromLeft]; [self setAnimations: [NSDictionary dictionaryWithObject:transition forKey:@"subviews"]]; } - (void)setCurrentView:(NSView*)newView { if (!currentView) { currentView = newView; return; } [[self animator] replaceSubview:currentView with:newView]; currentView = newView; } -(IBAction) switchToViewOne:(id)sender { [transition setSubtype:kCATransitionFromLeft]; [self setCurrentView:viewOne]; } -(IBAction) switchToViewTwo:(id)sender { [transition setSubtype:kCATransitionFromRight]; [self setCurrentView:viewTwo]; }

  • WPF: Horizontal Alignment

  • Is there a scheduling algorithm that optimizes for "maker's schedules"?

    - by John Feminella
    You may be familiar with Paul Graham's essay, "Maker's Schedule, Manager's Schedule". The crux of the essay is that for creative and technical professionals, meetings are anathema to productivity, because they tend to lead to "schedule fragmentation", breaking up free time into chunks that are too small to acquire the focus needed to solve difficult problems. In my firm we've seen significant benefits by minimizing the amount of disruption caused, but the brute-force algorithm we use to decide schedules is not sophisticated enough to handle scheduling large groups of people well. (*) What I'm looking for is if there's are any well-known algorithms which minimize this productivity disruption, among a group of N makers and managers. In our model, There are N people. Each person pi is either a maker (Mk) or a manager (Mg). Each person has a schedule si. Everyone's schedule is H hours long. A schedule consists of a series of non-overlapping intervals si = [h1, ..., hj]. An interval is either free or busy. Two adjacent free intervals are equivalent to a single free interval that spans both. A maker's productivity is maximized when the number of free intervals is minimized. A manager's productivity is maximized when the total length of free intervals is maximized. Notice that if there are no meetings, both the makers and the managers experience optimum productivity. If meetings must be scheduled, then makers prefer that meetings happen back-to-back, while managers don't care where the meeting goes. Note that because all disruptions are treated as equally harmful to makers, there's no difference between a meeting that lasts 1 second and a meeting that lasts 3 hours if it segments the available free time. The problem is to decide how to schedule M different meetings involving arbitrary numbers of the N people, where each person in a given meeting must place a busy interval into their schedule such that it doesn't overlap with any other busy interval. For each meeting Mt the start time for the busy interval must be the same for all parties. Does an algorithm exist to solve this problem or one similar to it? My first thought was that this looks really similar to defragmentation (minimize number of distinct chunks), and there are a lot of algorithms about that. But defragmentation doesn't have much to do with scheduling. Thoughts? (*) Practically speaking this is not really a problem, because it's rare that we have meetings with more than ~5 people at once, so the space of possibilities is small.

  • Django: problem with merging querysets after annotation

    - by Björn Lilja
    Hi I have a manager for "Dialog" looking like this: class AnnotationManager(models.Manager): def get_query_set(self): return super(AnnotationManager, self).get_query_set().annotate( num_votes=Count('vote', distinct=True), num_comments=Count('comment', distinct=True), num_commentators = Count('comment__user', distinct=True), ) Votes and Comments has a ForeignKey to Dialog. Comments has a ForeignKey to User. When I do this: dialogs_queryset = Dialog.public.filter(organization=organization) dialogs_popularity = dialogs_queryset.exclude(num_comments=0) | dialogs_queryset.exclude(num_votes=0) ...dialogs_popularity will never returned the combination, but only the dialogs with more than 0 comments, or if I change the order of the OR, the dialogs with more than 0 votes!
