• Java Sound Clip Looping Frame Position

  - by InsertNickHere

  Hi, I have a little problem with a loopting clip: If you have a soundfile e.g. 20000 samples long, the frame position will not reset after looping, so I get values that are "out of bounds" of the original soundfile. As I want to draw a position marker on my waveform, I'm a bit confused how to achive. At this time I just get myClip.getLongFramePosition() but this does not work as described above. Does anyone have an idea how to fix that? Is there a possibility to count how often a clip was looped before? Regards

• iphone/ipad with 2 side by side tables

  - by jesse001

  I want to create a view with 2 tables side by side, where selecting the row on 1 table effects the content of the other and vice versa (not parent child). My problem is how to send the request. I started with a utility app using core data, and added 2 table view controllers. I added these to the main view nib and moved the tables to the view. One table controls a list from Core Data, then on selecting a row I want it to move to the other table which is based on a mutable array. On didselectrow I want to tell the other table to update, however I can only find samples that are parent/child so involves initializing. Does anyone know of a way to do this for an active view? Thanks heaps for your help.

• Free PHP framework/library for single-sign on / cross domain login

  - by Dennis Cheung

  I am looking for free (non GPL is better) SSO framework/library implementation or code samples. There are many kind of SSO implementation. Sharing cookie, sharing session, one time token, associative accounts, etc, etc. (BTW, any good article compare them?) Is there any keyword I should google and reuse before before I start to implement our own wheel. I know OpenID, but which is too much and it is not our need. We rather keep it KISS. We just want share the credentials of user that could save users from another login form.

• How can I convert spaces to tabs in Vim or Linux?

  - by cwd

  I've looked over several questions on Stack Overflow for how to convert spaces to tabs without finding what I need. There seem to be more questions about how to convert tabs to spaces, but I'm trying to do the opposite. In Vim I've tried :retab and :retab! without luck, but I believe those are actually for going from tabs to spaces anyways. I tried both expand and unexpand at the command prompt without any luck. Here is the file in question: http://gdata-python-client.googlecode.com/hg-history/a9ed9edefd61a0ba0e18c43e448472051821003a/samples/docs/docs_v3_example.py How can I convert leading spaces to tabs using either Vim or the shell?

• Building Outline Data in Google Maps (Android)

  - by scotty.hoag

  I'm working on an Android project that focuses on knowing how close you are to buildings. I wanted to know if there is some way to extract the geographic information about the outlines of buildings out of the Google Maps API. Thanks. EDIT: The functionality I'm looking for is similar to what's going on in this app. (Click the link near the top of the page that says "View Live Sample".) http://resources.esri.com/help/9.3/arcgisserver/apis/javascript/gmaps/help/google_start.htm#topics/samples/identify_features.html

• How do I control output files name and content of an Hadoop streaming job?

  - by Eran Kampf

  Is there a way to control the output filenames of an Hadoop Streaming job? Specifically I would like my job's output files content and name to be organized by the ket the reducer outputs - each file would only contain values for one key and its name would be the key. Update: Just found the answer - Using a Java class that derives from MultipleOutputFormat as the jobs output format allows control of the output file names. http://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/mapred/lib/MultipleOutputFormat.htmlhttp://hadoop.apache.org/core/docs/current/api/org/apache/hadoop/mapred/lib/MultipleOutputFormat.html I havent seen any samples for this out there... Can anyone point out to an Hadoop Streaming sample that makes use of a custom output format Java class?

• iPhone: Switching Views From Outside Root Controller

  - by senfo

  I am using a UINavigationController to switch between views. What I would like is for each view to have the ability to control when it is swapped out for another view by having buttons within the view. All of the samples I've seen thus far have placed buttons on a toolbar, which is located on the root view containing the Switch View Controller rather than the views, them self. Is it possible to do what I want? I can't figure how to wire up the connection back to the UINavigationController. I'm having a difficult time wording this, so please feel free to let me know if you need additional clarification.

• Android how do I wait until a service is actually connected?

  - by Ryan

  I have an Activity calling a Service defined in IDownloaderService.aidl: public class Downloader extends Activity { IDownloaderService downloader = null; // ... In Downloader.onCreate(Bundle) I tried to bindService Intent serviceIntent = new Intent(this, DownloaderService.class); if (bindService(serviceIntent, sc, BIND_AUTO_CREATE)) { // ... and within the ServiceConnection object sc I did this public void onServiceConnected(ComponentName name, IBinder service) { Log.w("XXX", "onServiceConnected"); downloader = IDownloaderService.Stub.asInterface(service); // ... By adding all kinds of Log.xx I found that the code after if(bindService(...)) actually goes BEFORE ServiceConnection.onServiceConnected is being called - that is, when downloader is still null - which gets me into trouble. All the samples in ApiDemos avoid this timing problem by only calling services when triggered by user actions. But what should I do to right use this service after bindService succeeds? How can I wait for ServiceConnection.onServiceConnected being called reliably?

• Performance: float to int cast and clippling result to range

  - by durandai

  I'm doing some audio processing with float. The result needs to be converted back to PCM samples, and I noticed that the cast from float to int is surprisingly expensive. Whats furthermore frustrating that I need to clip the result to the range of a short (-32768 to 32767). While I would normally instictively assume that this could be assured by simply casting float to short, this fails miserably in Java, since on the bytecode level it results in F2I followed by I2S. So instead of a simple: int sample = (short) flotVal; I needed to resort to this ugly sequence: int sample = (int) floatVal; if (sample > 32767) { sample = 32767; } else if (sample < -32768) { sample = -32768; } Is there a faster way to do this? (about ~6% of the total runtime seems to be spent on casting, while 6% seem to be not that much at first glance, its astounding when I consider that the processing part involves a good chunk of matrix multiplications and IDCT)

• Microphone input

  - by George

  I'm trying to build a gadget that detects pistol shots using Android. It's a part of a training aid for pistol shooters that tells how the shots are distributed in time and I use a HTC Tattoo for testing. I use the MediaRecorder and its getMaxAmplitude method to get the highest amplitude during the last 1/100 s but it does not work as expected; speech gives me values from getMaxAmplitude in the range from 0 to about 25000 while the pistol shots (or shouting!) only reaches about 15000. With a sampling frequency of 8kHz there should be some samples with considerably high level. Anyone who knows how these things work? Are there filters that are applied before registering the max amplitude. If so, is it hardware or software? Thanks, /George

• How to post on Facebook with Android using the latest SDK

  - by user645402

  All the samples I have seen so far seem to be using an earlier version of the SDK and the parameters and calls don't match. Using the latest SDK, I'm trying this: String access_token = facebook.getAccessToken(); Bundle bundle = new Bundle(); bundle.putString("access_token", access_token); bundle.putString("app_id", FACEBOOK_APP_ID); bundle.putString("message", "My First Post"); bundle.putString("description", "My First Description"); asyncrunner.request("me/feed", bundle, new RequestListener() { And i get back a call to onComplete() with response = "{"data":[]}. And nothing ever gets posted to my wall on FB. Perhaps I'm not waiting long enough? How long should I need to wait before it shows up?

• Restoring a saved opengl ES buffer (i.e. writing it back to screen)

  - by Adam

  I'm writing an iPhone app where I need to save and load the screen contents. I was able to save the screen using glReadPixels(), but since there's no glDrawPixels() in openGL ES, I'm having a lot of trouble restoring that buffer to the screen. I gather that I need to save the screen as a texture: http://stackoverflow.com/questions/708760/what-is-the-equivalent-of-gldrawpixels-in-opengl-es-1-1 But I'm not sure how to implement this. Does anyone have or know of any code samples that do this? I'm an openGL noob, so any help would be greatly appreciated :)

• C# - Keep track of open child forms

  - by Nate Shoffner

  I currently have a parent control (Form1) and a child control (Form2). Form1 contains a listview that stores a list of of file data (each file is a separate item). Form2 contains only a textbox. Upon clicking on one of these listviewitems in Form1, Form2 is opened up and accesses the file's data and loads it into the textbox in Form2 in plain text format. The issue I'm having is, I would like to be able to detect, upon clicking of a listviewitem, whether that file is already opened in said child form and if so, to activate it (bring it to the front) and if it is not already opened, open it. I'm not sure what the best method of doing this would be since this can involve many child forms being open at once. This is not an MDI application. Any ideas on how this could be accomplished are appreciated and samples even more so. Thank you.

• is it possible to write data to a collection in wpf?

  - by randyc

  Hello. In looking through samples I have seen a number of examples where it is possible to present data within a wpf applicaiton by binding to collections. However I was wondering is it possible to write to a collection from an applicaiton. Say for example i have 2 or more fields such as names and I wanted to have hte ability to add up to three names in my application ( all stored in memory). Will collections serve this purpose. In the past with asp.net I have done this by creating data tables and storing values on the fly or during the session. I am trying to learn WPF and I was wondering if collections work in the same fashion? If so could you please post an example or point me to references that show examples of this? Thank you in advance.

• EXC_BAD_ACCESS from AudioBuffer

  - by jfalexvijay

  I am trying to do the record using AudioUnit for iPhone app. Changes: (start) I have added the following code bufferList = (AudioBufferList *)malloc(sizeof(AudioBuffer)); bufferList-mNumberBuffers = 1; bufferList-mBuffers[0].mNumberChannels = 2; bufferList-mBuffers[0].mDataByteSize = 1024; bufferList-mBuffers[0].mData = calloc(256, sizeof(uint32_t)); Changes: (end) static OSStatus recordingCallback(void *inRefCon, AudioUnitRenderActionFlags *ioActionFlags, const AudioTimeStamp *inTimeStamp, UInt32 inBusNumber, UInt32 inNumberFrames, AudioBufferList *ioData) { OSStatus status; status = AudioUnitRender(appdelegate-audioUnit, ioActionFlags, inTimeStamp, inBusNumber, inNumberFrames, appdelegate-bufferList); if(status != 0) NSLog(@"AudioUnitRender status is %d", status); SInt16* samples = (SInt16*)(ioData-mBuffers[0].mData); ..... } fixed: (I am getting OSStatus -50 error code)- Because I didn't initialize the bufferList. I am EXC_BAD_ACCESS from AudioBuffer (ioData-mBuffers[0].mData). I am not sure with this error. Please help me to resolve it.

• Problem with passing folder path string to web service function via jQuery.ajax

  - by the_V

  Hello, I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file): var d = "{'str':'<%=System.DateTime.Now.ToString() %>', 'applicationPath':'<%=GetApplicationPath() %>'}"; $.ajax({ type: "POST", url: "http://localhost/testwebsite/TestWebService.asmx/Test", data: d, contentType: "application/json; charset=utf-8", dataType: "json", error: function (xhr, status, error) { var err = eval("(" + xhr.responseText + ")"); alert(err.Message); }, success: function (msg) { } }); That's what GetApplicationPath method looks like: protected string GetApplicationPath() { return HttpUtility.HtmlEncode(Request.PhysicalApplicationPath); } And here is a header of web-service function which I'm trying to call: public void Test(string str, string applicationPath) Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:\Projects\Samples\mytestwebsite\'". How can I overcome this?

• Screenflow based application in Adobe Flex/Flash

  - by iceman

  I'm searching for some code samples for my Flash application. The app is based on screen-flows , i.e each screen is defined with some visual elements with some buttons which have async events associated with them(consuming web services basically). The buttons also have functionality to go back and forth between screens and jump to any screen. I want to define all of the visual elements and the functionality of the events in a XML file. Thus the model, view and controller are all in the XML. Does any framework allow this like Pure MVC? Where can I find some examples of this kind of functionality that I want?

• How do you create a daemon in Python?

  - by DavidM

  Searching on Google reveals x2 code snippets. The first result is to this code recipe which has a lot of documentation and explanation, along with some useful discussion underneath. However, another code sample, whilst not containing so much documentation, includes sample code for passing commands such as start, stop and restart. It also creates a PID file which can be handy for checking if the daemon is already running etc. These samples both explain how to create the daemon. Are there any additional things that need to be considered? Is one sample better than the other, and why?

• How do I change the number of thumbnails seen in the Android sample Home application?

  - by Todd

  I am working with the sample Home application project on http://developer.android.com/resources/samples/Home/index.html I've added another value to the THUMBS_IDS and IMAGE_IDS Integer arrays in the Wallpaper class for a total of four wallpaper options. When I run the application with Device API version 7, Skin: HVGA, hw.lcd.density: 160, in portrait layout, the fourth wallpaper option is not shown. I need to use the directional keys in the emulator to see the 4th wallpaper option, because the first option is centered. I have modified only the wallpaper.xml file with a variety of android:layout_* options with no success at this point. How do I show all four of my wallpaper options?

• Programming terms - field, member, properties (C#)

  - by Petr

  Hi, I was trying to find meaning of this terms but especially due to language barrier I was not able to understand what they are used for. I assume that "field" is variable (object too?) in the class while "property" is just an object that returns specific value and cannot contain methods etc. By "member" I understand any object that is declared on the class level. But these are just my assumptions based on commented code samples where some careful programmers used "property region" etc. I would really appreciate if someone could explain it to me.

• What format is your documentation in?

  - by Ek0nomik

  I am going to be writing documentation for two web services that I developed, and I started wondering what people on here do for documentation. Do you create it in an HTML file so it can be viewed in the browser? Word document? Wiki? What do you guys/gals use? I was originally leaning towards creating an HTML page since it seems a little more open and friendly than a word document. Plus I can use the prettify javascript to make code samples look nice. Our company has a Sharepoint though, so an HTML file may not be the best choice given that most documentation is put up in spreadsheets and word documents.

• Metro style apps with Html and C#

  - by labroo

  According to this slide http://geekswithblogs.net/images/geekswithblogs_net/technetbytes/windows-8-platform-tools.jpg Does it mean I have to use XAML view with C# if I want to develop a metro styled application? Can I use a HTML/JS/CSS - C# combination with event handlers and all? Something like ASP.NET Webforms/MVC . I know it is not the same client server architecture, but since metro styled apps support HTML/JS, I was wondering. I can use Win-JS. But can I rather write C# than Javascript, and use HTML rather than XAML?(I dont know XAML and I like C#) All the C# samples I found online use XAML.
