  • XCode linking error when targeting armv7.

    - by Tom
    I've already spent countless hours puzzling over this, utilizing Google searches and other Stack Overflow questions to no avail. I have an iPhone/iPad universal application, which seems to compile fine when the target is armv6. However, when the device is iPad, I get this warning: warning: building for SDK 'Device - iPhone OS 3.2' requires an armv7 architecture. Oddly enough, the app still runs great on iPad in spite of this warning. However, I do want to do things the "right way" what ever that means in this case. When I switch the target architecture to armv7, I get linking errors: "___restore_vfp_d8_d15_regs", referenced from: *redacted* "___save_vfp_d8_d15_regs", referenced from: *redacted* ld: symbol(s) not found collect2: ld returned 1 exit status The "redacted" portions of the errors are references to the static library to which I'm trying to link. Here's what I've tried from the many suggestions online. Each of these were suggested more than once without any explanation, which leads me to believe nobody quite understands this problem: "Never use the drop down menu in the upper left of the XCode window to choose the target. Instead, set this to Base SDK and then the Base SDK to iPhone OS 3.0 in the target configuration. Set the target device to your preferred target (iPad, iPhone OS 3.2 in my situation.)" This yields the error "Library not found for -lcrt1.3.1.o" "Make sure that GCC isn't linking against the wrong version of the standard library. (You'll have to make sure the LIBRARY_SEARCH_PATH doesn't have the wrong path in it.)" My LIBRARY_SEARCH_PATH is already empty, so this doesn't seem relevant. "Try compiling with GCC 4.0 rather than GCC 4.2." I get a syntax error inside a UIKit header file. The error is "Syntax error before 'AT_NAME' token." The line is "UIKIT_EXTERN @interface UILocalizedIndexedCollation : NSObject." Another project compiles just fine with the same target settings, which is really making me question my sanity. Could I be dealing with a corrupt XCode project? If anyone knows what's actually happening and has a reference or doesn't mind explaining it, I would be so very grateful. Cheers!

  • Detect Installed Application URI Handler on Webkit browsers

    - by Punit Raizada
    Guys, I have a question mainly related to the Iphone web browser but I am hoping the same solution would work on other browsers that are webkit based. I have a application (Iphone + Android) that registers a handler for custom URI (appuri://) on the Phone. I am able to launch the application by making a link to "appuri://act/launch" from my web pages. This works only if my application is installed on the device. If the device does not have the app installed then a message comes up "Safari was not able to open ....". What I want to do is detect if the URI Scheme is supported from the browser and then prompt my own message saying "please download the app ..blah blah blah" if the handler for the URI scheme is not found. Is there a way I can detect or find the list of URL Scheme handlers on the Phone from the Web Browser ?

  • Can someone provide an example of seeking, reading, and writing a >4GB file using boost iostreams

    - by Queueless
    I have read that boost iostreams supposedly supports 64 bit access to large files semi-portable way. Their FAQ mentions 64 bit offset functions, but there is no examples on how to use them. Has anyone used this library for handling large files? A simple example of opening two files, seeking to their middles, and copying one to the other would be very helpful. Thanks.

  • iphone - presenting an alertview with the right orientation

    - by Mike
    I have to present an alertview when my app starts. My app supports both landscape modes. Despite the landscape mode the device is when the app starts the alertview always shows in portrait. I have tried to use the accelerometer to detect the interface orientation before the orientation notification and I have the correct orientation 2 seconds before the alertview showing. Then, I use this code to set the status bar to a different orientation, hoping the alertview will follow... [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight]; or left, depending on the landscape mode. Nothing works. Is there a way to force the alertview to respect the orientation? The point here is this: I cannot set one landscape orientation in particular for the status bar, I have to detect the orientation the device is on and then set the status bar orientation. thanks for any help.

  • Help make sense of a KillDisk error/log

    - by user284194
    I have a hard drive that I've been trying to reformat. I tried reformatting it in the windows XP and 7 installers, and in an Ubuntu live cd with gparted. I tried using dd to 'zero' the drive as well with no success. Finally I ran across KillDisk after a search. I tried to zero the disk again with KillDisk and after 8 hours of zeroing I get the following errors in the log: ----------------------------------------Erase Session Begin--------------------------------------- 2010-03-23 19:35:54 Active@ KILLDISK for Windows Build 5.1.39 started Target: WDC WD2500KS-00MJB0 232.9 GB Located on: WDC WD2500KS-00MJB0 (Serial number: WD-WCANK9604799) Erase method: One Pass Zeros (1 pass) Passes: 1 Bad (unwritable) sectors detected from 1701 to 488397167 on Hard Disk 1.

  • iPhone Simulator 3.x not supported after upgrading to XCode 3.2.3 Beta4 with OS 4.0

    - by Jon
    I've been having some problems, & since you guys are the smartest devs I thought I'd just ask you. When I last installed Xcode 3.2.3 Beta 2 (OS 4.0 support), it had all the iPhone Device & Simulator 3.x. Now, updated to Xcode 3.2.3 Beta 4 (OS 4.0 support), it no longer lists 3.x SDKs for either simulator or device in XCode. I'm aware that 3.2.3 changes the BASE SDK to 4.0, but how come none of the 3.x devices are available either? When I go to: /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs The only two files available are: iPhoneSimulator3.2.sdk iPhoneSimulator4.0.sdk However, when I go to: /Developer/Platforms/iPhoneOS.platform/DeviceSupport 3.0 3.0.1 3.1 3.1.1 3.1.2 3.1.3 3.2 4.0 (8A274b)

  • Activity restart on rotation Android

    - by Isaac Waller
    In my Android application, when I rotate the device (slide out the keyboard) then my activity is restarted (onCreate is called). Now, this is probably how it's supposed to be, but I do a lot of initial setting up in the onCreate method, so I need either: 1. Put all the initial setting up in another function so it's not all lost on device rotation or 2. Make it so onCreate is not called again and the layout just adjusts or 3. Limit the app to just portrait so that onCreate is not called.

  • Universal iPhone/iPad application debug compilation error for iPhone testing

    - by andybee
    I have written an iPhone and iPad universal app which runs fine in the iPad simulator on Xcode, but I would now like to test the iPhone functionality. I seem unable to run the iPhone simulator with this code as it always defaults to the iPad? Instead I tried to run on the device and as it begins to run I get the following error: dyld: Symbol not found: _OBJC_CLASS_$_UISplitViewController Referenced from: /var/mobile/Applications/9770ACFA-0B88-41D4-AF56-77B66B324640/Test.app/Test Expected in: /System/Library/Frameworks/UIKit.framework/UIKit in /var/mobile/Applications/9770ACFA-0B88-41D4-AF56-77B66B324640/Test.app/TEST As the App is built programmatically rather than using XIB's, I've split the 2 device logics using the following lines in the main.m method: if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate_Pad"); } else { retVal = UIApplicationMain(argc, argv, nil, @"AppDelegate_Phone"); } From that point forth they use different AppDelegates and I've checked my headers to ensure the UISplitView is never used nor imported via the Phone logic. How do I avoid this error and is there a better way to split the universal logic paths in this programmatically-created app?

  • Scrubbing IPv4 dotted-quad addresses in SQL

    - by pilcrow
    Given a table containing dotted quad IPv4 addresses stored as a VARCHAR(15), for example: ipv4 -------------- 172.16.1.100 172.16.50.5 172.30.29.28 what's a convenient way to SELECT all "ipv4" fields with the final two octets scrubbed, so that the above would become: ipv4 ------------ 172.16.x.y 172.16.x.y 172.30.x.y Target RDBMS is postgresql 8.4, but the more portable the better!

  • UITableView backgroundColor always grey on iPad

    - by rjobidon
    Hi, When I set the backgroundColor for my UITableView it works fine on iPhone (device and simulator) but NOT on the iPad simulator. Instead I get a light grey background for any color I set including groupTableViewBackgroundColor. Steps to reproduce: Create a new navigation-based project. Open RootViewController.xib and set the table view style to "Grouped". Add this responder to the RootViewController:- (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor blackColor]; } Select Simulator SDK 3.2, build and run. You will get a black background (device and simulator). Select your target in the project tree. Click on Project : Upgrade Current Target for iPad. Build and run. You will get a light grey background. Revert the table view style to Plain and you will get a black background. Thanks for your help!

  • How can I connect to Android with ADB over TCP?

    - by martinjd
    I am attempting to debug an application on a Motorola Droid but I am having some difficulty connecting to the device via USB. My development server is a Windows 7 64bit VM running in HyperV and so I cannot connect directly via USB in the guest or from the host. I installed a couple of different USB over TCP solutions but the connection appears to have issues since the adb monitor reports "devicemonitor failed to start monitoring" repeatedly. I was wondering if there is a way to connect directly from the client on the development machine to the daemon on the device using the network instead of the usb connection or possibly other viable options?

  • View controllers inside tab bar controller not auto-resizing on rotation

    - by Padawan
    (Correction: the view controllers are not auto-resizing instead of not auto-rotating.) In an iPad app, I have five regular view controllers (not navigation controllers or anything like that) inside a tab bar controller. The tab bar controller is just a plain UITabBarController declared in the app delegate. All the view controllers return YES in the shouldAutorotateToInterfaceOrientation method. On both the simulator and device, on rotation, the tab bar and the current view controller rotate but the currently selected view controller (call it A) does not resize properly. It keeps its portrait width and height (but it is rotated). If I switch to another view controller B and then back to A (without rotating the device again), A appears correctly resized. This happens with any of the five view controllers Why doesn't the currently selected view controller resize immediately on rotation and how do I fix it? Thanks.

  • Scanning notification through WIA

    - by Przemek
    I've registered to receive WIA notifications for all devices through RegisterEventCallbackInterface for WIA_EVENT_DEVICE_CONNECTED and WIA_EVENT_SCAN_IMAGE events. However I only receive notifications when scanner device is plugged in - I don't receive notification when I scan (for example with mspaint which uses WIA). Am I supposed to receive scanning notifications from applications or only when Scan button is pressed on a device? (I haven't tried the latter since I use a multifunction printer without Scan button). Is there any other way to be notified about successful scans through WIA? Thank you.

  • App starts in 1.5 emulator but doesn't in 1.6

    - by DixieFlatline
    My app works on 1.5 emulator and 1.5 device. When i try to start it on 1.6 emulator, it produces strange exceptions (doesn't even start). I don't have any 1.6 device to try this app if it works on a real device. I get some warnings in Eclipse ( warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. This class was probably produced by a broken compiler.) and get cant rid of them (i think they come from some apache jars that i need to make http multipart posts). Is it possible that this jars are cause for my exceptions in 1.6 or is it something else?

  • App store name and info.plist

    - by user346194
    Hi guys, I've just completed my first app and having tested I'm ready for submission. However, despite numerous web searches and reading, I'm struggling to finalise the method required to enable me to have a different name on the app store to the name that appears under the app on the device home screen. In the plist.info file there is reference to bundle display name, executable name, bundle name, bundle identifier, product name etc. So, for example, say I would like the app store name to display as: HELLO WORLD and I would like the name below the icon on the device home screen to display as: HELLO How should I enter the data in the plist.info file to achieve the above? Many thanks in advance for your help. Gav.

  • Good Package for Fitting Polynomial Trend Lines

    - by Rev316
    Given a simple data set, I would like to be able to calculate a trending formula given it's a second order polynomial regression. In fact, it would be great if one could even forecast X periods during calculation (similar to what Excel does). I'm looking for a portable C/C++ package that's relatively easy to use, and allows it to spit out the "best-fit" (highest R^2 value) curve. Any suggestions? Thanks!

    Hi, Im working with a CD722UN Customer Display for our POS application. it comes with a USB2.0 connection and a installation package containing a driver ect.. now, for my application. how should i do when i want to access this driver? at the moment i'm using the "CD722UN application"s .dll path but that can warry from clients OS ect.. Declare Function opencd722usb Lib "C:\Program\cd7220 USB\cd722dusb.dll" () As Boolean Declare Function writecd722usb Lib "C:\Program\cd7220 USB\cd722dusb.dll" (ByRef dataoutput As Byte, ByVal Length As Integer) As Integer Declare Function readcd722usb Lib "C:\Program\cd7220 USB\cd722dusb.dll" (ByRef DataInput As Byte, ByVal size As Integer) As Integer Declare Function closecd722usb Lib "C:\Program\cd7220 USB\cd722dusb.dll" () As Boolean my first thought was to first check if there was a device installed in the device manager and somehow use the driver from there??? or distribute the .dll inside our application folder and use searchpath ""installed directory"\cd722dusb.dll" what is the best solution? thanks in advance!

  • problem with two .NET threads and hardware access

    - by mack369
    I'm creating an application which communicates with the device via FT2232H USB/RS232 converter. For communication I'm using FTD2XX_NET.dll library from FTDI website. I'm using two threads: first thread continuously reads data from the device the second thread is the main thread of the Windows Form Application I've got a problem when I'm trying to write any data to the device while the receiver's thread is running. The main thread simply hangs up on ftdiDevice.Write function. I tried to synchronize both threads so that only one thread can use Read/Write function at the same time, but it didn't help. Below code responsible for the communication. Note that following functions are methods of FtdiPort class. Receiver's thread private void receiverLoop() { if (this.DataReceivedHandler == null) { throw new BackendException("dataReceived delegate is not set"); } FTDI.FT_STATUS ftStatus = FTDI.FT_STATUS.FT_OK; byte[] readBytes = new byte[this.ReadBufferSize]; while (true) { lock (FtdiPort.threadLocker) { UInt32 numBytesRead = 0; ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead); if (ftStatus == FTDI.FT_STATUS.FT_OK) { this.DataReceivedHandler(readBytes, numBytesRead); } else { Trace.WriteLine(String.Format("Couldn't read data from ftdi: status {0}", ftStatus)); Thread.Sleep(10); } } Thread.Sleep(this.RXThreadDelay); } } Write function called from main thread public void Write(byte[] data, int length) { if (this.IsOpened) { uint i = 0; lock (FtdiPort.threadLocker) { this.ftdiDevice.Write(data, length, ref i); } Thread.Sleep(1); if (i != (int)length) { throw new BackendException("Couldnt send all data"); } } else { throw new BackendException("Port is closed"); } } Object used to synchronize two threads static Object threadLocker = new Object(); Method that starts the receiver's thread private void startReceiver() { if (this.DataReceivedHandler == null) { return; } if (this.IsOpened == false) { throw new BackendException("Trying to start listening for raw data while disconnected"); } this.receiverThread = new Thread(this.receiverLoop); //this.receiverThread.Name = "protocolListener"; this.receiverThread.IsBackground = true; this.receiverThread.Start(); } The ftdiDevice.Write function doesn't hang up if I comment following line: ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead);

  • HTC Sense UI / Sprint on HTC Evo

    - by fordays
    Hey. Longtime lurker, first time poster. I just got a HTC Evo 4G from Google i/o. Its a great device, but I don't like how Sprint and HTC got replaced all of the native apps that were added on after 2.0 such as Gallery. The Gallery app on the phone uses flickr and facebook connect. I want to sync my Picasa albums. How can i get put the true Google applications on this device?

  • Windows CE 5.0 emulator needed

    - by Heinzi
    I need an emulator for Windows CE 5.0 to test an embedded device (not PDA or smartphone) application that I am developing. This is what I have already tried: Visual Studio 2008 Pro includes an emulator. Unfortunately, it does not include a Windows CE image (only Windows Mobile and Smartphone). Yes, there is a difference, see the screenshots here. Windows CE includes a "start button", windows that can be minimized, moved around etc. There is a Windows CE Device Emulator available from Microsoft. Apart from the fact that its license only permits non-commercial use, it does not run in Windows 7 (it requires .net Framework 1.1, which is incompatible with Windows 7) nor in Windows XP mode (error message: "Emulator for Windows CE will not run one virtual machine within another. Please run the virtual machine on the host operating system"). Is there any option that I have missed?

  • iOS6 Twitter integration

    - by Peter Warbo
    There seems to be a difference between the iPhone simulator and actual device when checking if Twitter is available. I check if a Twitter account is setup by using this code: [SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]; In the simulator there is a nice UIAlertView informing the user that there are no Twitter accounts setup and two buttons one for Settings and one for Cancel. However when I run my app on my device it will not show the above UIAlertView. Why is that? And how can I catch what button is tapped in the above UIAlertView (since I did not instantiate it?) This is what it looks like on the simulator:
