  • How do you determine with CLLocationManager when a user denies access to location services?

    - by Brennan
    With CLLocationManager I can use the following code to determine if I can access location services on the device. This is the master setting for all apps and can be turned on and off. if (self.locationManager.locationServicesEnabled) { [self.locationManager startUpdatingLocation]; } But a user can deny access to an individual app and in order to not execute the code to use the location manager I need to know if the user approved access to location services for this specific app. I saw that at one point there was a property called locationServicesApproved which appears it would indicate if the user approved access to location services in this app. But it was removed in 2008. Source: http://trailsinthesand.com/apple-removes-notifications-from-iphone-sdk-beta-4/ It appears that there is no way to determine if the user approved access to location services but that seems to be a big hole in the SDK. Is this feature in the SDK elsewhere? What can I do to determine if the user has approved access to location services for the current app?

  • Getting Safari document title/location with Scripting Bridge does not work in full-screen mode

    - by Mark
    I'm trying to get the URL and document title from the topmost Safari document/tab. I have an AppleScript and an objective-c version using Apple's Scripting Bridge framework. Both versions work fine for most web pages, however when I open a Youtube video in full-screen mode, the Scripting Bridge based version fails. The Apple Script works fine for "normal" and full-screen Safari windows. Can anyone see what is wrong with the Scripting Bridge code below to cause it to fail for full-screen Safari windows? Here the code (I omitted error checking for brevity): AppleScript: tell application "Safari" # Give us some time to open video in full-screen mode delay 10 do JavaScript "document.title" in document 0 end tell Scripting Bridge: SafariApplication* safari = [SBApplication applicationWithBundleIdentifier:@"com.apple.Safari"]; SBElementArray* windows = [safari windows]; SafariTab* currentTab = [[windows objectAtIndex: 0] currentTab]; // This fails when in full-screen mode: id result = [safari doJavaScript: @"document.title" in: currentTab]; NSLog(@"title: %@", result); Scripting Bridge error (with added line breaks): Apple event returned an error. Event = 'sfri'\'dojs'{ '----':'utxt'("document.title"), 'dcnm':'obj '{ 'want':'prop', 'from':'obj '{ 'want':'cwin', 'from':'null'(), 'form':'indx', 'seld':1 }, 'form':'prop', 'seld':'cTab' } } Error info = { ErrorNumber = -1728; ErrorOffendingObject = <SBObject @0x175c2de0: currentTab of SafariWindow 0 of application "Safari" (238)>; } I could not find details about the given error code. It complains about 'currentTab' which shows that the JavaScript event at least made it all the way to Safari. I assume that the current tab receives the event, but refuses to run the JS code, because it is in full-screen mode. However, why does this work for an AppleScript? Don't they use the same code path eventually? Any suggestions are greatly appreciated. Thanks!

  • A problem with connected points and determining geometry figures based on points' location analysis

    - by StolePopov
    In school we have a really hard problem, and still no one from the students has solved it yet. Take a look at the picture below: http://d.imagehost.org/0422/mreza.gif That's a kind of a network of connected points, which doesn't end and each point has its own number representing it. Let say the numbers are like this: 1-23-456-78910-etc. etc.. (You can't see the number 5 or 8,9... on the picture but they are there and their position is obvious, the point in middle of 4 and 6 is 5 and so on). 1 is connected to 2 and 3, 2 is connected to 1,3,5 and 4 etc. The numbers 1-2-3 indicate they represent a triangle on the picture, but the numbers 1-4-6 do not because 4 is not directly connected with 6. Let's look at 2-3-4-5, that's a parallelogram (you know why), but 4-6-7-9 is NOT a parallelogram because the in this problem there's a rule which says all the sides must be equal for all the figures - triangles and parallelograms. Also there are hexagons, for ex. 4-5-7-9-13-12 is a hexagon - all sides must be equal here too. 12345 - that doesn't represent anything, so we ignore it. I think i explained the problem well. The actual problem which is given to us by using an input of numbers like above to determine if that's a triangle/parallelogram/hexagon(according to the described rules). For ex: 1 2 3 - triangle 11 13 24 26 -parallelogram 1 2 3 4 5 - nothing 11 23 13 25 - nothing 3 2 5 - triangle I was reading computational geometry in order to solve this, but i gave up quickly, nothing seems to help here. One friend told me this site so i decided to give it a try. If you have any ideas about how to solve this, please reply, you can use pseudo code or c++ whatever. Thank you very much.

  • Specifying location of new inlineshape in Word VBA?

    - by Branan
    I'm working on a document "wizard" for the company that I work for. It's a .dot file with a header consisting of some text and some form fields, and a lot of VBA code. The body of the document is pulled in as an OLE object from a separate .doc file. Currently, this is being done as a Shape, rather than an InlineShape. I did this because I can absolutely position the Shape, whereas the InlineShape always appears at the beginning of the document. The problem with this is that a Shape doesn't move when the size of the header changes. If someone needs to add or remove a line from the header due to a special case, they also need to move the object that defines the body. This is a pain, and I'd like to avoid it if possible. Long story short, how do I position an InlineShape using VBA in Word? Oh, and this is for a 10-year-old system setup, so Office '97.

  • Modal View Controller with keyboard on landscape iPad changes location when dismissed

    - by Roi
    I present a modal view controller on my on my iPad with UIModalPresentationFormSheet presentation style and UIModalTransitionStyleCoverVertical transition style. The Modal View Controller contains a UIWebView with some TextFields on it. When the user taps one of the text fields the keyboard comes up. I have noticed that in landscape mode after the keyboard is shown, if I try to dismiss the modal view controller with animation the view changes its position from the center of the screen to the left side just before the animation starts.. This happens only if the keyboard is up and only in landscape mode on the iPad. If the user closes the modal view without pressing on any text field this doesn't happen. Anyone familiar with this strange behavior?

  • how to know location of return address on stack c/c++

    - by Dr Deo
    i have been reading about a function that can overwrite its return address. void foo(const char* input) { char buf[10]; //What? No extra arguments supplied to printf? //It's a cheap trick to view the stack 8-) //We'll see this trick again when we look at format strings. printf("My stack looks like:\n%p\n%p\n%p\n%p\n%p\n% p\n\n"); //%p ie expect pointers //Pass the user input straight to secure code public enemy #1. strcpy(buf, input); printf("%s\n", buf); printf("Now the stack looks like:\n%p\n%p\n%p\n%p\n%p\n%p\n\n"); } It was sugggested that this is how the stack would look like Address of foo = 00401000 My stack looks like: 00000000 00000000 7FFDF000 0012FF80 0040108A <-- We want to overwrite the return address for foo. 00410EDE Question: -. Why did the author arbitrarily choose the second last value as the return address of foo()? -. Are values added to the stack from the bottom or from the top? apart from the function return address, what are the other values i apparently see on the stack? ie why isn't it filled with zeros Thanks.

  • Swing: Scroll to bottom of JScrollPane, conditionally on current viewport location

    - by I82Much
    Hi all, I am attempting to mimic the functionality of Adium and most other chat clients I've seen, wherein the scrollbars advance to the bottom when new messages come in, but only if you're already there. In other words, if you've scrolled a few lines up and are reading, when a new message comes in it won't jump your position to the bottom of the screen; that would be annoying. But if you're scrolled to the bottom, the program rightly assumes that you want to see the most recent messages at all times, and so auto-scrolls accordingly. I have had a bear of a time trying to mimic this; the platform seems to fight this behavior at all costs. The best I can do is as follows: In constructor: JTextArea chatArea = new JTextArea(); JScrollPane chatAreaScrollPane = new JScrollPane(chatArea); // We will manually handle advancing chat window DefaultCaret caret = (DefaultCaret) chatArea.getCaret(); caret.setUpdatePolicy(DefaultCaret.NEVER_UPDATE); In method that handles new text coming in: boolean atBottom = isViewAtBottom(); // Append the text using styles etc to the chatArea if (atBottom) { scrollViewportToBottom(); } public boolean isAtBottom() { // Is the last line of text the last line of text visible? Adjustable sb = chatAreaScrollPane.getVerticalScrollBar(); int val = sb.getValue(); int lowest = val + sb.getVisibleAmount(); int maxVal = sb.getMaximum(); boolean atBottom = maxVal == lowest; return atBottom; } private void scrollToBottom() { chatArea.setCaretPosition(chatArea.getDocument().getLength()); } Now, this works, but it's janky and not ideal for two reasons. By setting the caret position, whatever selection the user may have in the chat area is erased. I can imagine this would be very irritating if he's attempting to copy/paste. Since the advancement of the scroll pane occurs after the text is inserted, there is a split second where the scrollbar is in the wrong position, and then it visually jumps towards the end. This is not ideal. Before you ask, yes I've read this blog post on Text Area Scrolling, but the default scroll to bottom behavior is not what I want. Other related (but to my mind, not completely helpful in this regard) questions: Setting scroll bar on a jscrollpane Making a JScrollPane automatically scroll all the way down. Any help in this regard would be very much appreciated.

  • Location of the object after scrolling in UIScrollView

    - by ludo
    Hi, I have a scrollView (width:320px height:100px) on my UIView, inside it I add 10 images with width:106.5px each. After that I use this function to have 3 different parts inside my scrollView, so everytime I scroll, an image will automatically be center. -(void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate { [self returnToPosition:self.scrollView]; } -(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView { [self returnToPosition:self.scrollView]; } -(void)returnToPosition:(UIScrollView *)scrollView { CGFloat itemWidth = 106.5f; CGFloat position = [self.scrollView contentOffset].x; CGFloat newPosition = 0.0f; CGFloat offSet = position / itemWidth; NSUInteger target = (NSUInteger)(offSet + 0.5f); newPosition = target * itemWidth; [self.scrollView setContentOffset:CGPointMake(newPosition, 0.0f) animated:YES]; } Here is my question, I want to be able to know which image will be in the middle position after the user scroll the View, because I want to display on my UIView a text, specific to that image. But I don't know how to do that. Some Ideas?

  • what POIs (Point of Interests) DB can I use for a commercial app

    - by Ellie
    Hi, I need a POI database for a startup project I am working on - it will be a free basic version and a premium paid for version in the sense that user will pay a monthly subscription. I would like to use foursquare type checkin to places and plancast type functionality to search for places (one-line search). Ie I need to: - perform a search for POIs around a location - associate users to that POI, with a time stamp - allow users to add own POIs - provide free-text search for POIs (a la google one-line search) Google API allows great search, but I understand there are limits in number of requests that can be done? This would prevent scaling, and may result in application breaking when too many users. Also what does google T&C say about using this in a paid for service? Openstreetmap I understand does not have these contstraints, but do they also provide a good one-line search type API? Or how could I solve this? Many thanks for any advice, Ellie

  • Getting text at clicked location in an HTML element

    - by Marc
    I have a div element containing some text. When the user clicks a word inside that div I'd like to highlight just that word. In order to do this I need to know what character position in the text the click occurred at, so I can then locate nearby whitespace and insert some formatting around the word. Finding out where the click occurred within the text is the trick here. Is that kind of thing possible?

  • Changing IIS URL Rewrite config location

    - by adam
    Hi When used at site level, the IIS7 URL Rewrite 2 module saves its configuration in the web.config file of that site. I'm using Sitecore CMS, and best practice is to store any web.config customisations in a separate config file for ease of upgrading, staging/production setups etc. Is there any way to specify a different config file for IIS7 redirects? I know that application-level rewrites are stored in ApplicationHost.config, but I have several sites running on the server and would like to keep them separated. Thanks, Adam

  • How do I put files in the TFS Build drop location

    - by Scott Langham
    Hi, I'm new to using TFS build. I've got a build defined that runs as a continuous integration. It creates a drop folder, but there's nothing in it. What's the best practice for moving stuff in the drop folder? I've seen a Binaries folder, do I need to copy things into their, or do I alter the TFSbuild.proj in some way to copy the files I want to the drop folder? Thanks.

  • Zedgraph textobj X location depends on text length?

    - by Tony_Henrich
    I have a Zedgraph textobj which I want to place always in the same x, y position (ASP.NET image). I noticed that the text doesn't always show in the same starting x position. It shifts depending on the text's length. I tried to have the text to have the same length by padding it with spaces. It helped a little but the result is not always consistent. I am using PaneFraction for coordType. What's the proper method to have a piece of text to always show in the same x position. I am using textobj as a title because the native title property always shows up centered and I need my title be left aligned to the graph.

  • Web service reference location?

    - by Damien Dennehy
    I have a Visual Studio 2008 solution that's currently consisting of three projects: A DataFactory project for Business Logic/Data Access. A Web project consisting of the actual user interface, pages, controls, etc. A Web.Core project consisting of utility classes, etc. The application requires consuming a web service. Normally I'd add the service reference to the Web project, but I'm not sure if this is best practice or not. The following options are open to me: Add the reference to the Web project. Add the reference to the Web.Core project, and create a wrapper method that Web will call to consume the web service. Add a new project called Web.Services, and copy step 2. This project is expected to increase in size so I'm open to any suggestions.

  • Cutom event dispatchment location

    - by Martino Wullems
    Hello, I've been looking into custom event (listeners) for quite some time, but never succeeded in making one. There are so many different mehods, extending the Event class, but also Extending the EventDispatcher class, very confusing! I want to settle with this once and for all and learn the appriopate technique. package{ import flash.events.Event; public class CustomEvent extends Event{ public static const TEST:String = 'test'; //what exac is the purpose of the value in the string? public var data:Object; public function CustomEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, data:Object = null):void { this.data = data; super(); } } } As far as I know a custom class where you set the requirements for the event to be dispatched has to be made: package { import flash.display.MovieClip; public class TestClass extends MovieClip { public function TestClass():void { if (ConditionForHoldToComplete == true) { dispatchEvent(new Event(CustomEvent.TEST)); } } } } I'm not sure if this is correct, but it should be something along the lines of this. Now What I want is something like a mouseevent, which can be applied to a target and does not require a specific class. It would have to work something like this: package com.op_pad._events{ import flash.events.MouseEvent; import flash.utils.Timer; import flash.events.TimerEvent; import flash.events.EventDispatcher; import flash.events.Event; public class HoldEvent extends Event { public static const HOLD_COMPLETE:String = "hold completed"; var timer:Timer; public function SpriteEvent(type:String, bubbles:Boolean=true, cancelable:Boolean=false) { super( type, bubbles, cancelable ); timer = new Timer(1000, 1); //somehow find the target where is event is placed upon -> target.addEventlistener target.addEventListener(MouseEvent.MOUSE_DOWN, startTimer); target.addEventListener(MouseEvent.MOUSE_UP, stopTimer); } public override function clone():Event { return new SpriteEvent(type, bubbles, cancelable); } public override function toString():String { return formatToString("MovieEvent", "type", "bubbles", "cancelable", "eventPhase"); } ////////////////////////////////// ///// c o n d i t i o n s ///// ////////////////////////////////// private function startTimer(e:MouseEvent):void { timer.start(); timer.addEventListener(TimerEvent.TIMER_COMPLETE, complete); } private function stopTimer(e:MouseEvent):void { timer.stop() } public function complete(e:TimerEvent):void { dispatchEvent(new HoldEvent(HoldEvent.HOLD_COMPLETE)); } } } This obviously won't work, but should give you an idea of what I want to achieve. This should be possible because mouseevent can be applied to about everything.The main problem is that I don't know where I should set the requirements for the event to be executed to be able to apply it to movieclips and sprites. Thanks in advance

  • Routing a location that matches one controller to another
