  • Turn a page (a UIWebView) with an animation

    - by Stefan
    Hi, I have a webview, which shows the pages of a ebook. I want to switch from one page to the next page with a page curl animation. By now, I'm know how to switch the page and how to apply a page curl animation on the webview. But how do I apply the curl animation in a way that it looks like flipping from one page to another?

  • Authenticating with Netflix: Netflix OAuth vs. SignPost OAuth: Which is correct?

    - by Stefan Kendall
    With signpost 1.2: String authUrl = provider.retrieveRequestToken( consumer, callbackUrl ); Netflix API response: <status> <status_code> 400 </status_code> <message> oauth_consumer_key is missing </message> </status> I see how to craft the URL manually via the netflix documentation, but this seems to contradict other services which use OAuth authentication. Who's incorrect, here? Is there a way to get signpost to work with Netflix, aside from contributing to the signpost source? :P

  • Can I programatically get hold of the Autos/local variables that is shown when debugging?

    - by Stefan
    Im trying to build an error-logger that loggs running values that is active in the function that caused the error. (just for fun so its not a critical problem) When going in break-mode and looking at the locals-tab and autos-tab you can see all active variables (name, type and value), it would be useful to get hold of that for logging purposes when an error occur and on some other occasions. For my example, I just want to find all local variables that are of type string and integer and store the name and value of them. Is this possible with reflection? Any tips or pointers that get me closer to my goal would be very appreciated. I have toyed with using expression on a specifik object (a structure) to create an automapper against a dataset, but I have not done anything like what I ask for above, so please make me happy and say its possible. Thanks.

  • Nexus One & Windows XP USB Driver

    - by Stefan
    I've been unable to get my Nexus One working as a development phone on Windows XP. I've got the driver (revision 3 for N1 support), I've got it installed according to the official installation guide, and the phone appears in the Device Manager just as the guide says it should. However, adb still can't find the phone. 'adb devices', for example, returns no active devices. Am I forgetting some basic step? One thing I've noticed is that the driver is labeled in Windows as version 2 released November, 2009 (I need version 3 from January 2010 for N1 support). However, I've never had version 2 installed. I've used the SDK to download version 3 several times - even deleted it and redownloaded it. I've uninstalled/reinstalled the version 3 driver multiple times. It still says version 2. Is this the problem, or this something completely unrelated? Note: The phone is working as a dev phone on Ubuntu, so I know the phone/cable/etc. are good. It's either my fault or the driver's.

  • Usability: Do mac users understand "right-click"?

    - by Stefan Kendall
    I have a feature of my application which depends on alternate-click. Windows users don't understand "alternate-click" though, and I was wondering if most mac users understood "right-click", and if so if they were offended or annoyed when they see such text. Does anyone have experience developing usable (consumer) applications for mac users? Does anyone have any opinions on this?

  • Put DrawingGroup on a Canvas?

    - by stefan.at.wpf
    Hello, I have a DrawingGroup and I want to put it on a Canvas, but because DrawingGroup is no UIElement, this is not possible. Whats the best way to do this? And from which class could I derive, so that I could do something like canvas1.Children.Add(new myDrawingGroup()); (Meaning I want to add my DrawingGroup as one element on the canvas, instead of several single Drawings / Geometries. I also need hit testing and databinding support.) Thank you very much for any hint!

  • Android: Nexus One - Geocoder causes IOException - works perfectly with other devices and emulator

    - by Stefan Klumpp
    The code below works perfectly for real devices running on 1.5, 1.6 and 2.0 as well as the emulator running on 2.1. However, executing it on the Nexus One (running 2.1) raises an IOException: java.io.IOException: Unable to parse response from server at android.location.Geocoder.getFromLocation(Geocoder.java:124) That's the code snippet where it happens: Double myLatitude = AppObject.myLocation.getLatitude(); Double myLongitude = AppObject.myLocation.getLongitude(); DEBUG.i(TAG, "My location: " + myLatitude + " | " + myLongitude); Geocoder geocoder = new Geocoder(MainActivity.this); java.util.List<Address> addressList; try { addressList = geocoder.getFromLocation(myLatitude, myLongitude, 5); if(addressList!=null && addressList.size()>0) { currentAddress = new String(); DEBUG.i(TAG,addressList.get(0).toString()); currentAddress = addressList.get(0).getAddressLine(0) + ", " + addressList.get(0).getAddressLine(1) + ", " + addressList.get(0).getAddressLine(2); } return true; } catch (IOException e) { e.printStackTrace(); return false; }

  • SoundManager2 has irregular latency

    - by Stefan Monov
    I'm playing some notes at regular intervals. Each one is delayed by a random number of milliseconds, creating a jarring irregular effect. How do I fix it? Note: I'm OK with some latency, just as long as it's consistent. Answers of the type "implement your own small SoundManager2 replacement, optimized for timing-sensitive playback" are OK, if you know how to do that :) but I'm trying to avoid rewriting my whole app in flash for now. For an example of app with zero audible latency see the flash-based ToneMatrix. Testcase (see it here live or get it in an zip): <head> <title></title> <script type="text/javascript" src="http://www.schillmania.com/projects/soundmanager2/script/soundmanager2.js"> </script> <script type="text/javascript"> soundManager.url = '.' soundManager.flashVersion = 9 soundManager.useHighPerformance = true soundManager.useFastPolling = true soundManager.autoLoad = true function recur(func, delay) { window.setTimeout(function() { recur(func, delay); func(); }, delay) } soundManager.onload = function() { var sound = soundManager.createSound("test", "test.mp3") recur(function() { sound.play() }, 300) } </script> </head> <body> </body> </html>

  • Opened SerialPort crashes C# application

    - by Stefan Teitge
    The computer is connected to measuring device via a physical COM1. I have simple form where I open a serial port, tell the device that I'm alive and occasionally the device sends data. (every some minutes) Thread _readThread = new Thread(Read); SerialPort _serialPort = new SerialPort("COM1", 9600); _serialPort.Parity = Parity.None; _serialPort.DataBits = 8; _serialPort.StopBits = StopBits.One; _serialPort.Handshake = Handshake.None; _serialPort.DtrEnable = true; _serialPort.Open(); _readThread.Start(); _serialPort.Write("#listening"); The read function (which works): public void Read() { string message = _serialPort.ReadLine(); } After approximately one minute the application crashes (even while debugging). It reports an ObjectDisposedException (for the underlying stream?). The message tells that the SafeHandle was closed. Stack strace is below: at Microsoft.Win32.UnsafeNativeMethods.GetOverlappedResult(SafeFileHandle hFile, NativeOverlapped lpOverlapped, Int32& lpNumberOfBytesTransferred, Boolean bWait) at System.IO.Ports.SerialStream.EventLoopRunner.WaitForCommEvent() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()* Any ideas? The problem is reported widely but usually involve the device beeing physically detached from the PC.

  • Quaddratic Bezier Curve: Calculate Tangent

    - by stefan.at.wpf
    Hello, I have have a quadratic bezier curve and I want to calculate the slope of the tangent in a given point. For example, let it be the middlepoint of the quadratic bezier curve, therefore t=0.5 (please see the link below for a picture of this). I've calculated the first derivation of the formula for the quadratic bezier curve, however I get 400 as value for the slope, though it should be 0. Maybe I'm using the first derivation in a wrong way? I know I could also calculate the tangents using trigonometric functions, however I'd like to do it using the first derivation, shouldn't this be possible? Thanks for any hint! For clarification / please note: I'm interested in a general way to get the slope in a arbitrary given point on a quadratic bezier curve, not only to get the tangent in the start- and end point. A picture of my problem including the text above: http://cid-0432ee4cfe9c26a0.skydrive.live.com/self.aspx/%c3%96ffentlich/Quadratic%20Bezier%20Curve.pdf Thank you very much for any hint!

  • Screenshot from WPF application as SVG / vector graphic?

    - by stefan.at.wpf
    Hello, is it possible to create a screenshot of a WPF application as SVG / is there some WPF built-in function to get the XAML code for the current drawn window that then can be converted to SVG? I need some screenshots for documenting a WPF application and I'd like them to be zoomable like a WPF program is using e.g. Snoop or Vista Magnifyer. Thanks for any hint!

  • C# UTF8 output keep encoded characters intact

    - by Stefan Pohl
    Hello, i have a very simple question I can't seem to get my head around. I have a properly encoded UTF8-String I parse into a JObject with Json.NET, fiddle around with some values and write it to the commandline, keeping the encoded characters intact. Everything works great except for the keeping the encoded characters intact part. Code: var json = "{roster: [[\"Tulg\u00f4r\", 990, 1055]]}"; var j = JObject.Parse(json); for (int i = 0; i < j["roster"].Count(); i++) { j["roster"][i][1] = ((int)j["roster"][i][1]) * 3; j["roster"][i][2] = ((int)j["roster"][i][2]) * 3; } Console.WriteLine(JsonConvert.SerializeObject(j, Formatting.None)); Actual Output: {"roster":[["Tulgôr",2970,3165]]} Desired Output: {"roster":[["Tulg\u00f4r",2970,3165]]} It seems like my phrasing in Google is inappropriate since nothing useful came up. I'm sure it's something uber-easy and i will feel pretty stupid afterwards. :)

  • SWFObject redirectUrl not functional with ExpressInstall

    - by Stefan Kendall
    How do you specify a redirect URL for the adobe flash express install? I'm using swfobject 2.2, and while I thought MMredirectURL in the flashvars might be what I needed, this just doesn't work. I also tried setting redirectUrl in the attributes object before embedding the swf, but this doesn't work either. What is the proper way to specify a redirect URL to go through after the Express Install occurs with swfobject 2.2?

  • Why can't I install MVC (1 or 2) with Visual Web Developer Express 2008 RC1?

    - by Stefan
    Hi all, I have installed VWD 2010 Express and love MVC2. I have an existing ASP.NET 3.5 website that I'd like to redevelop with ASP.NET MVC2 under VWD 2008 with the 3.5 framework (the host only supports .Net 3.5, and Express 2010 doesn't support targeting of .Net framework versions) I am however unable to install MVC2 with VWD 2008. The installer (for 2008 SP1) says it has installed, but the MVC project templates don't show up when I create a new project. I also had this problem originally with MVC1 which is why I gave up at some point and just created it as a normal ASP.NET website. I tried uninstalling and installing VWD 2008, and then installing MVC2, but this didn't solve the problem. Does anyone know why this problem occurs, or how to solve it? Or is there a way to add these templates and the tooling manually?

  • What parser generator do you recommend

    - by stefan.ciobaca
    I'm currently shopping for a FOSS parser generator for a project of mine. It has to support either C or C++. I've looked at bison/flex and at boost::spirit. I went from writing my own to spirit to bison to spirit to bison to spirit, each time hit by some feature I found unpleasant. The thing I hate most about bison/flex is that they actually generate C/C++ source for you. There are a number of disadvantages to this, e.g. debugging. I like spirit from this point of view, but I find it very very heavy on syntax. I am curious about what you are using, what you would recommend, and general thoughts about the state of the art in parser generators. I am also curious to hear about approaches being used in other languages for parsing problems.

  • DoDragDrop disables MouseMove Events

    - by stefan.at.wpf
    After having started a Drag & Drop operation by DragDrop.DoDragDrop(...) no more MouseMove Events are fired. I even tried AddHandler(Window.MouseMoveEvent, new MouseEventHandler(myControl_MouseMove), true); where the last parameter means I even opt in for handled events. No chance, seems like the MouseMove Event is never fired at all! Any way to still get MouseMove Events while using Drag & Drop? I'd like to Drag & Drop a control, while dragging this control it shall follow the mouse pointer. Any idea how to do this in this case?
