  • GData API works in Android 2.0 SDK & up?

    - by user266361
    I used GData API to pull in Calender info. It works fine if I use 1.6. But the same code, if I change to Android 2.0 & up, it would throw AuthenticationException. Below is my code for ur ref: CalendarService myService = new CalendarService("My Application"); myService.setUserCredentials(args[0],args[1]); // Set up the URL and the object that will handle the connection: URL feedUrl = new URL("http://www.google.com/calendar/feeds/"+args[0]+"/private/full"); args[0] & args[1] are the credentials. AuthenticationException will be thrown when calling myService.setUserCredentials(). Anybody has any clue?

  • iPhone SDK - How is data shared in a universal app

    - by norskben
    Stack overflow I want to make a universal version of my app available, but I am wondering how is data managed between the iPad and the iPhone versions? -Are they completely independent? or if I have a plist in the iPad app, does it also appear in the iPhone app. If so, is there any syncing etc etc. I have a few months experience with single iPad or iPhone apps, but never a universal. Thanks again. UPDATE: I was interested in the files in the /Documents folder, does this automatically update on itunes syncing at all?

  • iPhone SDK allow touches to affect multiple views

    - by Parad0x13
    I have a main view that has has two buttons on it that control methods to display the next image and display the previous image. In this case the 'Image' is a class that inherits from UIImageView and has multiple pictures on it that you can interact with, and I call this class a 'Pane'. The pane itself handles all the user interaction itself while the main view controls the display of next and previous panes with the buttons. Here is my dilemma, because the pane fully covers the main view it wont allow for the user to tap the buttons on the main view! So once a pane pops up you cannot change it via the buttons! Is there a way to allow touches through transparent parts of a view, or if not how in the world do I achieve this?! I cannot pass touchesBegan or any of those methods from the pane to the superview because all of the button touch methods are created in the xib file. I cannot insert the pane under the control panel because then you wouldn't be able to interact with the pane. And as far as I know theres no way to pass touch events to every single pane within the paneHoldingArray that belongs to the main view I cannot add the command buttons inside of the pane because I want to be able to replace the command button's image with a thumbprint render of the next/previous pane. I've been stuck on this for a very long time, please somebody help me out with a fix action or a new way to re-engineer the code so that it will work!

  • implementing stretchable dialog borders in iphone sdk

    - by Joey
    Hi, I want to implement dialog borders that scale to the size I require the dialog to be. Perhaps there is a better more conventional name for this sort of thing. If there is, if someone would edit the title, that'd be great. Anyhow, I'd like to do this so I can have dialogs of any size without the visual artifacts that come with scaling border art to small, large, or wacky unproportional dimentions. I have a few ideas on how this is done, but am not sure which is better for iphone. I have a few questions. 1) Should I make a containing view object that basically overloads its drawRect method and draws the images where they should be at their appropriate scale when the method is called, or should I main a containing view object that simply contains 8 UIImageViews? I suspect the latter approach won't work if I need to actively scale the resulting dialog class like in an animation. 1b) If overloading drawRect is the way to go, does someone have some sample code or a link to an example that demonstrates drawing an image directly from drawRect()? 2) Is it generally better to create a) a 3 x 3 image where the segments are in their appropriate 1x1 grid of the image? If so, is it simple to draw from a portion of this image onto my target view in drawRect (if the former assumption is correct that I should use drawRect)? b) The pieces separately in 8 different files?

  • Head Rotation in Opposite Direction with GLM and Oculus Rift SDK

    - by user3434662
    I am 90% there in getting orientation to work. I am just trying to resolve one last bit and I hope someone can point me to any easy errors I am making but not seeing. My code works except when a person looks left the camera actually rotates right. Vice versa with looking right, camera rotates left. Any idea what I am doing wrong here? I retrieve the orientation from the Oculus Rift like so: OVR::Quatf OculusRiftOrientation = PredictedPose.Orientation; glm::vec3 CurrentEulerAngles; glm::quat CurrentOrientation; OculusRiftOrientation.GetEulerAngles<OVR::Axis_X, OVR::Axis_Y, OVR::Axis_Z, OVR::Rotate_CW, OVR::Handed_R> (&CurrentEulerAngles.x, &CurrentEulerAngles.y, &CurrentEulerAngles.z); CurrentOrientation = glm::quat(CurrentEulerAngles); And here is how I calculate the LookAt: /* DirectionOfWhereCameraIsFacing is calculated from mouse and standing position so that you are not constantly rotating after you move your head. */ glm::vec3 DirectionOfWhereCameraIsFacing; glm::vec3 RiftDirectionOfWhereCameraIsFacing; glm::vec3 RiftCenterOfWhatIsBeingLookedAt; glm::vec3 PositionOfEyesOfPerson; glm::vec3 CenterOfWhatIsBeingLookedAt; glm::vec3 CameraPositionDelta; RiftDirectionOfWhereCameraIsFacing = DirectionOfWhereCameraIsFacing; RiftDirectionOfWhereCameraIsFacing = glm::rotate(CurrentOrientation, DirectionOfWhereCameraIsFacing); PositionOfEyesOfPerson += CameraPositionDelta; CenterOfWhatIsBeingLookedAt = PositionOfEyesOfPerson + DirectionOfWhereCameraIsFacing * 1.0f; RiftCenterOfWhatIsBeingLookedAt = PositionOfEyesOfPerson + RiftDirectionOfWhereCameraIsFacing * 1.0f; RiftView = glm::lookAt(PositionOfEyesOfPerson, RiftCenterOfWhatIsBeingLookedAt, DirectionOfUpForPerson);

  • using crypto++ on iphone sdk with pycrypto on app engine

    - by Joey
    Hi, I'm trying to encrypt http requests using crypto++ and decrypt them with pycrypto on the app engine server end. Using Arc4 encryption, I can successfully encrypt and decrypt on the iphone end but when I try decrypting on app engine, the result is garbled. I thought maybe it has something to do with the encoding of the NSString but am not certain. It's not clear to me if I need to call encode() on the cipher on the server end before decrypting, although that does seem to resolve a failure to decrypt involving ascii values. I have a separate post that delves a bit into this. Can anyone offer some advice? http://stackoverflow.com/questions/2794942/crypto-pycrypto-with-google-app-engine

  • [Android SDK] Text-To-Speech addSpeech not working properly

    - by arcoraven
    Hi, I'm trying to get my Android app to play a .wav file recording of the word "Spinach Salad" whenever it sees that phrase being spoken by TTS. Here's the relevant code: spinach_salad.wav is located in /res/raw prodName = "Spinach Salad" mTts.addSpeech(prodName, "com.example.textextractor", R.raw.spinach_salad); ...and later in the code: mTts.speak("blah blah blah " + prodName, TextToSpeech.QUEUE_ADD, null); I've also tried: mTts.speak("blah blah blah Spinach Salad", TextToSpeech.QUEUE_ADD, null); and mTts.speak("blah blah blah", TextToSpeech.QUEUE_ADD, null); mTts.speak(productName_str, TextToSpeech.QUEUE_ADD, null); In both cases, I'm just hearing the TTS synthesized audio, rather than my custom .wav file. (On a related note, the last chunk of code sometimes speaks out of order, saying the second line before the first).

    We have some software running on Windows 7 on a mobile device (Panasonic Toughbook) which needs to initiate a 3g connection to download data. The WWAn adapter in question is a Gobi 2000. Is there any way of controlling the adapter direct from .net or should we fall back on Windows to initiate the connection as required (battery life is important).

  • Creating an mailto: URL with a URL in the body iPhone SDK

    - by Sjakelien
    UPDATE: I just found a similar post here: http://stackoverflow.com/questions/730101/how-do-i-encode-in-a-url-in-an-html-attribute-value Please consider the code below: I try to send an email message from within my iPhone app. The problem I encounter is that I want to put a URL in the body of the email. This URL contains two ampersands. I am encoding all the strings using "stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding", but the URL ends up in my new mail messagd truncated after the first ampersand. IE: "http://www.mydomain.nl/?cm=79&ctime=1246572000&cid=4772" becomes "http://www.mydomain.nl/?cm=79". Any suggestion what I could do to escape? NSString *eMailSubject = @"My Subject"; NSString *encodedSubject = [[NSString alloc] initWithString:[eMailSubject stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSString *eMailBody = @"http://www.mydomain.nl?cm=79&ctime=1246572000&cid=4772"; NSString *encodedBody = [[NSString alloc] initWithString:[eMailBody stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSString *urlString = [[NSString alloc] initWithString:[NSString stringWithFormat:@"mailto:?subject=%@&body=%@", encodedSubject, encodedBody]]; NSString *encodedURL = [[NSString alloc] initWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; NSURL *url = [[NSURL alloc] initWithString:encodedURL]; [[UIApplication sharedApplication] openURL:url];

  • IIS: Content-Length 0 for CSS, Javascript and Images

    - by Adrian Grigore
    After a clean re-installation of my Windows 7 system, I can't get IIS 7 to properly deliver any static content. Dynmic content (ASPX pages and content served by ASP.NET MVC controllers) works fine, but static files such as CSS, Javascript and Images give me a 200 OK status code and a Content-Length of 0. The problem occurs with all web sites on my server, even a brandnew ASP:NET MVC template project with no changes. It also occurs with both Firefox and IE 8. What could possibly be the problem? Note that I also installed the latest Windows Azure SDK, perhaps that messed up some settings. But I don't know how to proceed with for troubleshooting this.

    Before we continue: It can't be a predefined list. I need it sort of like this: http://loopj.com/tokeninput/demo.html ... A jQuery plugin that allows the user to type a string of words, press enter, and it makes it a block of text, from there they can press the X to get rid of it, or type more key words into the input area. I've found many things that do this, but all are pulling information from a predefined list of choices.

    I'm creating a child window within the main window. I assigned these styles to the child window: WS_CHILDWINDOW | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL | WS_SIZEBOX | WS_CAPTION The child window I get has a caption and a resizable border. However there's no close button in the caption, and the caption/border of the child window is not transparent (I'm using the aero theme in windows 7). Here is the screen snap: How to add close button to the caption? How can I make the caption/border transparent?
