• why does the gingerbread emulator orientation gets stuck in apps?

  - by tabjsina

  At first I thought this was a problem with my app, but it seems to be happening in any app (though interestingly, not the home screen) in the gingerbread emulator. To replicate my issue, open eclipse and fire up the android emulator for gingerbread (I'm using the "Google APIs - API Level 9" as my target) So the procedure to duplicate once the emulator loads is press LCtrl-F11 to shift orientation to landscape, then again to switch to portrait Result: In the homescreen: The view rotates to landscape, and then back to portrait, as expected In any app (i've tried browser, calculator, maps, and the app i'm currently working on): the view rotates to landscape, and then nothing, it stays in landscape even the emulator is displaying the phone in landscape mode (see below) http://i54.tinypic.com/2ake06v.jpg Has anyone else had this issue, or have I installed the emulator in some incorrect way - this hasn't been an issue with any of the previous emulators

• Getting information from an XML object in PHP

  - by errata

  Hi! I am using some XML parser to get some information from API, blah blah... :) In one place in my script, I need to convert string to int but I'm not sure how... Here is my object: object(parserXMLElement)#45 (4) { ["name:private"]=> string(7) "balance" ["data:private"]=> object(SimpleXMLElement)#46 (1) { [0]=> string(12) "11426.46" } ["children:private"]=> NULL ["rows:private"]=> NULL } I need to have this string "11426.46" stored in some var as integer. When I echo $parsed->result->balance I get that string, but if I want to cast it as int, the result is: 1. Please help! Thanks a lot!

• background picture for textview

  - by AndyAndroid

  Hi, I have a textview and a nine-patch image. Assigning this image in the xml editor to the tag "background" works as desired. Now I want to set this image dynamically in the coding, I thought myTextView.setBackgroundDrawable(mydrawable); would be the right thing to do. My png is in res/drawable. The API says that mydrawable needs to be an object of type drawable R.drawable.myninepatch is of type int. So my problem is that I have to convert from that int to a drawable somehow. Then I thought I can use a constructor NinePatchDrawable mydrawable = new NinePatchDrawable(); But I am again not able to construct such an object. Anyone an idea? Thanks.

• Save application preferences... registry/file?

  - by spender

  Where is the best place to store application preferences? In particular, I'd like to save preferences for a media player such as volume levels and the like. Two candidates spring to mind... file and registry. Which would be more appropriate? As a follow up to this, I'm also wondering if there are any APIs that aid in creating application specific settings. Unless someone advises me that this is wrong, I'd like to save stuff either in HKCU... or HKLM/Software/MyCompanyName/MyAppName/Key for the registry, or in %APPDATA\MyCompanyName\MyAppName\someTypeOfSettingsFile. As these seem to be commonly used for such settings, I'd assume that .Net makes it easy to store settings in these locations. Is there a simple high level API that can .Net offer me to read and write settings to these common locations?

• Custom marker changed to a black rectangle after clicking the marker few times on Google Map v2

  - by RajeevSahu

  Hi, How to avoid displaying black rectangles over the Custom marker. Actually Custom markers changed to a black image rectangle after clicking the marker few times on Google Map. I am using API V2. I am using Nokia N97 to display my google map with Custom markers. I am not sure, but I guess because of wi-fi connectivity, some times the connection lost, so at that moment when I click the Markers, they turned to black image rectangles. Any idea, how to avoid this thing. Thanks...

• JavaApplicationStub with CFBundleDocumentTypes

  - by mystro

  I'm trying to use CFBundleDocumentTypes to associate a custom file extension with my application. As far as I can tell, this seems to "work" -- JavaApplicationStub launches my application when I double click the file. However, no callback is registered through the ApplicationListener events I setup in java. I used the code listed in http://stackoverflow.com/questions/1460193/set-default-file-association-mac-os-x-java-package-maker-installer to do the file association, and the file association itself appears fine, but it seems as if it is the application stub trying to launch the file, and thus fails. I added the Apple ApplicatinListener code to my java application at (similar to http://developer.apple.com/mac/library/documentation/Java/Reference/1.5.0/appledoc/api/index.html?com/apple/eawt/Application.html) but it doesn't seem like my application ever gets a call back. the code is similar to Application.getApplicatin().addApplicationListener( new ApplicationAdapter() { public void handleOpenFile(ApplicationEvent evt) { //some logging message here that I never get} }); I should perhaps mention that I'm also using SWT... Any help would be appreciated

• C++: FFMPEG and SDL resources

  - by advs89

  I'm looking for resources (preferably books, but websites are fine too) for using FFMPEG and/or SDL with C++. Stuff I'd like to be able to do (eventually): Decode and play videos in realtime to a QT widget (the QT part isn't a problem) Overlay text and images on the video (in realtime) Loop video Cross-fade from one video to another (in realtime) Some kind of DVD functionality LIVE sources? (i.e. webcam, stream, etc.) So far I've looked at (and consider helpful) the following resources: FFMPEG and SDL Tutorial by Dranger (extremely helpful) StackOverflow: ffmpeg C API documentation/tutorial (not a duplicate, btw) Sample code bundled with FFMPEG libraries (I'll try and update this list with anything helpful below) Thanks for any help... Also: Operating System is Windows (but maybe one day cross-platform) Also 2: Resources using alternatives are welcome too... i.e. DirectShow, VFW, etc.

• Is there an easy way to copy an iterator into a list in Java?

  - by Space_C0wb0y

  I want something like this: public void CopyIteratorIntoList(Iterator<Foo> fooIterator) { List<Foo> fooList = new ArrayList<Foo>(); fooList.addAll(fooIterator); } which should be equivalent to: public void CopyIteratorIntoList(Iterator<Foo> fooIterator) { List<Foo> fooList = new ArrayList<Foo>(); while(fooIterator.hasNext()) fooList.add(fooIterator.next()); } Is there any method in the API to achieve that, or is this the only way?

• Nhibernate and not-exists query

  - by Dan

  I'm trying to construct a query in NHibernate to return a list of customers with no orders matching a specific criteria. My Customer object contains a set of Orders: <set name="Orders"> <key column="CustomerID" /> <one-to-many class="Order" /> </set> How do I contruct a query using NHibernate's ICriteria API to get a list of all customers who have no orders? Using native SQL, I am able to represent the query like this: select * from tblCustomers c where not exists (select 1 from tblOrders o where c.ID = o.CustomerID) I have been unable to figure out how to do this using aliases and DetatchedCriteria objects. Any guidance would be appreciated! Thanks!

• How to get notified of modification in the memory in Linux

  - by Song Yuan

  In a userspace program in Linux, I get a piece of memory via allocation from the heap, then the pointer is distributed to a lot of other components running in other threads to use. I would like to get notified when the said piece of memory is modified. I can of course develop a custom userspace solution for other components to use when they try to modify the memory. The problem in my case is that these are legacy components and they can write to memory in many occasions. So I'm wondering whether there is a similar API like inotify (get notified when file is changed) or other approaches in order to get notified when a piece of memory is changed. I considered using mmap and inotify, which obviously won't work if the changes are not flushed. Any suggestions are appreciated :-)

• How does one record audio from a Javascript based webapp?

  - by username

  I'm trying to write a web-app that records WAV files (eg: from the user's microphone). I know Javascript alone can not do this, but I'm interested in the least proprietary method to augment my Javascript with. My targeted browsers are Firefox for PC and Mac (so no ActiveX). Please share your experiences with this. I gather it can be done with Flash (but not as a WAV formated file). I gather it can be done with Java (but not without code-signing). Are these the only options? @dominic-mazzoni I'd like to record the file as a WAV because because the purpose of the webapp will be to assemble a library of good quality short soundbites. I estimate upload will be 50 MB, which is well worth it for the quality. The app will only be used on our intranet. UPDATE: There's now an alternate solution thanks to JetPack's upcoming Audio API: See https://wiki.mozilla.org/Labs/Jetpack/JEP/18

• Custom Rails Validation (Doesn't seem to be working)

  - by Karl Entwistle

  Hey guys ive got the following Model for Accounts require 'net/http' require 'uri' require 'date' class Account < ActiveRecord::Base validates_presence_of :username, :password, :on => :update validate :valid_expiry_date, :on => :update def valid_expiry_date reply = Net::HTTP.get URI.parse("http://api.rapidshare.com/cgi-bin/rsapi.cgi?sub=getaccountdetails_v1&type=prem&login=" + username + "&password=" + password) account = Time.at(reply[80..90].to_i) if (Time.now + 2419200) <= account return true else return false errors.add_to_base("Sorry this account isnt valid") end end end I know the code works in a ruby.rb file and will return true or false, however I seem to be having rather a lot of difficultly trying to translate this code into an actual validation, any help would be much appreciated. Thanks :) Its also defiantly at least connecting to the website as my firewall asked me if the Terminal was aloud to access it. At the moment not only is it displaying no errors its actually letting anything through and saving it.

• Getting normal information from OpenGL render output

  - by okamiueru

  I'll try to keep this simple. I want a way to access the normal information of the scene, from the Frame Buffer output (or similar). The same way one is able to access the Depth Buffer using glGetTexImage and GL_DEPTH_COMPONENT. I know I could set up a fragment shader which outputs the normal information in RGB color space, which could in turn be read from the rendered image. I'm wondering however if there is a way to do this within the openGL API. I'll clarify anything upon request as best as I can, Thank you

• How do you compare music data

  - by Chris

  i want to write an app to rename sort and organize my music library (mp3's, wav's, flac's). I wanted to take a portion of the song, say the first minutes, and compare that to a database and then retrieve the song name and tag information. I have heard that you can do this with last.fm but a look through their api info didn't help. My question is, what is this called so i can google it better? nothing i am trying is helping much. This would be similar to the shazam android app. My prefered language would be java, so i can run it on a few operating systems easier, but that might be subject to change depending on how i can do it. Thanks

• What's the best way to return a subset of a list

  - by Pikrass

  I have a list of tasks. A task is defined by a name, a due date and a duration. My TaskManager class handles a std::list<Task> sorted by due date. It has to provide a way to get the tasks due for a specific date. How would you implement that ? I think a good way (from API point of view) would be to provide a std::list<Task>::iterator pair. So I would have a TaskManager::begin(date) method. Do you think this method should get the iterator by iterating from the start of the list until it finds the first task due on that date, or by getting it from a std::map<date, std::list<Task>::iterator> (but then we have to keep it up-to-date when adding or removing tasks) ? And then, how could I implement the TaskManager::end(date) method ?

• Detecting the Loopback Adapter

  - by BlueSkies

  What is the best way for detecting whether a network interface is a loopback adapter? The windows API's GetAdaptersInfo and GetAdaptersAddresses state in the documentation that they will return whether an interface is a loopback through the Type (MIB_IF_TYPE_LOOPBACK) but neither of these do for the Microsoft Loopback Adapter at least, it is reported as a standard ethernet interface. I could try checking for the default MAC of the Loopback adapter but this can be easily spoofed. I could check for the name "Microsoft Loopback Adapter" in the description but this may have translation issues and may lead to other issues. IP addresses can also be changed. What is the most robust method for doing this?

• Third party lib to create jar files?

  - by Synesso

  I've Goog'd but I can't find any third party library that will let you create a jar file programmatically. I amazed that even Apache commons-io doesn't seem to have such functionality. I'd rather not implement it myself as the API is rather low level. Are there any 3rd party libraries out there that will do the job? Edit: I meant programmatically in Java. I don't want to drop out to the shell and I don't want to work with java.io.*.

• Locking DB w/ Large Reads (Ruby-on-Rails/Heroku)

  - by Splashlin

  Currently I have a Web API running on Heroku that is constantly writing information we're collecting from other data sources (currently theres about half a GB of data and it's growing very quickly). We're looking to add a reporting system on top of the current database that we can use to extract useful information out of the DB. The problem is that when we're running reports we're locking the DB and any other sites communicating with the DB are timing out. Does anyone have any solutions on how to solve this type of issue? Amazon RDS seems to have some interesting stuff with database replication but I don't know if that will solve my problems. Any advice would be greatly appreciated. Thanks

• Can I put google map functions into a closure?

  - by Joe

  I am trying to write some google map functionlity and playing around with javascript closures with an aim to try organise and structure my code better. I have the following code: var gmapFn ={ init : function(){ if (GBrowserIsCompatible()) { this.mapObj = new GMap2($("#map_canvas")); this.mapObj.setCenter(new google.maps.LatLng(51.512880,-0.134334),16); } } } Then I call it later in a jquery doc ready: $(document).ready(function() { gmapFn.init(); }) I have set up the google map keys and but I get an error on the main.js : uncaught exception: [Exception...

• Facebook Open Graph - Grab how many times a page has been liked?

  - by DoMx

  I have a site that allows users to create a saying and then users "like" those sayings on Facebook. http://www.likeylikey.net/ I got a friend to throw up this simple code in less than 2 hours so it's basic. He knows little to nothing regarding the Open Graph API. Basically, I want to know how I can programmatically store how many times a page has been liked so I can list a "Top 10, most liked pages" list. Right now the index shows a list of all created pages and now I just wish to show the 10 most liked but I need a way of pulling that information from Facebook. Is this possible?

• DeferWindowPos and SWP_SHOWWINDOW/SWP_HIDEWINDOW

  - by Tom Bell

  I am writing a virtual desktop application which utilises the DeferWindowPos API functions. The current method I am using is moving the windows off the screen if they're not on the current virtual desktop. However I know wish to also hide the windows that are off-screen so they do not appear on the task bar. I have attempted this by also passing SWP_SHOWWINDOW/SWP_HIDEWINDOW to the DeferWindowPos() calls. I have read a few sites regarding this and one of them suggested that if SWP_SHOWWINDOW/SWP_HIDEWINDOW are passed, then the window will only show or hide, and no reposition. Can anyone confirm this, or am I doing something wrong?

• Controling CRT memory initialization

  - by Ofek Shilon

  Occasionally you meet bugs that are reproducible only in release builds and/or only on some machines. A common (but by no means only) reason is uninitialized variables, that are subject to random behaviour. E.g, an uninitialized BOOL can be TRUE most of the time, on most machines, but randomly be initialized as FALSE. What I wish I would have is a systematic way of flushing out such bugs by modifying the behaviour of the CRT memory initialization. I'm well aware of the MS debug CRT magic numbers - at the very least I'd like to have a trigger to turn 0xCDCDCDCD (the pattern that initializes freshly allocated memory) to zeros. I suspect one would be able to easily smoke out nasty initialization pests this way, even in debug builds. Am I missing an available CRT hook (API, registry key, whatever) that enables this? Anyone has other ideas to get there?

• OpenId with Desktop Application ?

  - by user284523

  We're using an API from a provider; in their next version, they would provide an OpenId server but mostly the users are using their desktop application. An other website we're building would be opened from this application and we supposedly would connect with openid to access the resources stored in this provider. Still I don't understand how this would work if user is already authenticated with the desktop, will they have to authenticate an other time ? What happens if they close their browser and reopen it, will they have to to do it again ?

• about service accounts and unregistered users

  - by user1500824

  I have a web app in php mysql, I want to use one google drive account for my app. Can I use my app's accounts instead of google users for privilages. I read in SDK I can use service account to login without promting user, but I don't know how to share or give permissions files for custom users. In api reference I found this: "The user is not necessarily yet a Google user (e.g. if a file or folder is shared with an email address that does not yet have an associated Google account). Example: 1111459233037698895607". How a custom user in my app should get a token for own privilages.
