• Android playing Video data from a custom network stream?

  - by Cinar

  Does Android MediaPlayer can only work with file sources? I would like play media (video) from a network stream, but the stream comes in a non-standard protocol, so I have to somehow feed Android MediaPlayer with the data only. Is there anyway to do that? I found a few web pages suggesting using a temporary file for the buffered media data etc. but I would like to minimize the I/O usage as much as I can, so I'm looking for a API only solution if there is any? how about JNI? but looks like the permissions going to be an issue with that also.

• How to change mime type of email notifications sent by PeopleSoft?

  - by skanjo

  I work near some PeopleSoft guys and they asked how to change a link in an email notification sent by PeopleSoft so that it is friendly, basically they just wanted the use of an HTML anchor. After sitting down with them and looking through the code I found that the default mime type for all email notifications is text/plain and there does not seem to be any kind of an email API that is called which would allow setting the mime type of the body to text/html. Furthermore, there seems to be no general email configuration in PeopleSoft to, for example, set the default mime type for all emails. Do you know how to change the mime type of an email in PeopleSoft?

• Changing Pushpin Text Color

  - by Yawus

  I'm attempting to display data through the text of a Pushpin object. However, the text color defaults to white which is nigh-invisible when the backdrop is a road-style MapView. Looking through the API, paying especially close attention to PushpinOptions, I couldn't find anything that manipulated text color. Considering that this seems to a fairly basic feature, I'm a little confused as to why it doesn't exist or at least is really hard to find. Am I missing something or does Bing Maps for Android really not let you change the default text color for a Pushpin object?

  - by user2926082

• Giant online image gallery - How do I avoid OutOfMemoryError?

  - by Ben L.

  For anyone who's wondering, the gallery is http://www.spore.com/sporepedia. My app uses the Spore API to get the 100 newest creations, then displays them in a GridView. The text data about the creations is easy to store, but the images present a problem. As far as I know, I can either keep the images in a Hashtable or grab them every time they are viewed. Neither of these will work - the Hashtable quickly presents an OutOfMemoryError, and the constant reloading causes a lot of load on the server and a lot of lag on the client. Is there a better way to store the images?

• How can I do printing in Java with layouts instead of low level coordinates?

  - by Jonas

  I need to to some printing from my Java Swing application. I have tried to use Java Tutorials, but everything is very low level, and time-consuming. I have to specify the coordinates for every line that I want to print. It it also very lowlevel to use text, because I have to use FontMetrics and calculate what space all text fills up. Is there any easier way to to printing in Java? I would like to design the documents with something like layout managers instead. Any good library or API?

• How can I generate a unique ID using a hash in Perl?

  - by sganesh

  I doing message transfer program between multiple clients and server. I want to generate unique message id for every messages. that should be generated by server and return to client. For message transfer I am using hash data structure, Ex: { api => POST, username => sganesh, pass => "pass", message => "hai", time => "current_time", } I want to generate unique id using this hash. I have tried some of the ways, MD5 and freeze but this give unreadable id. I want some meaningful or readable unique id. I have thought we can use micro seconds to differentiate the id but here the problem is multiple clients. In any situation my id should be unique. Can anyone help me out of this problem?

• How to execute a large PHP Script ?

  - by atif089

  Well basically I may want to execute a script that may take as much as 1 hours as well. What I really want to do is Send SMS to my users using a third party API. So its basically like I supply my script with an array of phone numbers and fire the method to send SMS. However assuming it take 5 seconds to send 1 SMS and I want to send 1000 SMS which is roughly 1 - 2 hours. I can use set_time_limit() because I am on shared host. One way to do this is store numbers in a session and execute each SMS and use javascript to refresh that page until end. This way I need to keep my browser open and the execution will stop if my Internet Connection is disconnected. So, Is there any better way to do this ? Hope I am clear enough to explain what I want? I want to execute a large script that may take hours to execute without getting timeout.

• basic json > struct question

  - by danwoods

  I'm working with twitter's api, trying to get the json data from http://search.twitter.com/trends/current.json which looks like: {"as_of":1268069036,"trends":{"2010-03-08 17:23:56":[{"name":"Happy Women's Day","query":"\"Happy Women's Day\" OR \"Women's Day\""},{"name":"#MusicMonday","query":"#MusicMonday"},{"name":"#MM","query":"#MM"},{"name":"Oscars","query":"Oscars OR #oscars"},{"name":"#nooffense","query":"#nooffense"},{"name":"Hurt Locker","query":"\"Hurt Locker\""},{"name":"Justin Bieber","query":"\"Justin Bieber\""},{"name":"Cmon","query":"Cmon"},{"name":"My World 2","query":"\"My World 2\""},{"name":"Sandra Bullock","query":"\"Sandra Bullock\""}]}} My structs look like: type trend struct { name string query string } type trends struct { id string arr_of_trends []trend } type Trending struct { as_of string trends_obj trends } and then I parse the JSON into a variable of type Trending. I'm very new to JSON so my main concern is making sure I've have the data structure correctly setup to hold the returned json data. I'm writing this in 'Go' for a project for school. (This is not part of a particular assignment, just something I'm demo-ing for a presentation on the language)

• Downloading large files with AFNetworking

  - by goodfella

  I'm trying to implement downloading of a large file and show to user current progress, but block in: -[AFURLConnectionOperation setDownloadProgressBlock:] returns incorrect bytesRead and totalBytesRead values (they are smaller than they should be). For example: If I have a 90MB file and when it downloads completely, latest block invocation in setDownloadProgressBlock: gives me totalBytesRead value about 30MB. On other side, if file is 2MB large, latest block invocation gives correct totalBytesRead 2MB value. AFNetworking is updated to the latest version from github. If AFNetworking can't do it correctly, what solution can I use? Edit: I've determined that even if file is not downloaded completely (and this happens every time with relatively big file) AFNetworking calls success block in: -[AFHTTPRequestOperation setCompletionBlockWithSuccess:failure] I asked a similar question here about this situation, but didn't get any answers. I can check in code downloaded and real file sizes, but AFNetworking has no API for continuation of partial download.

• [Rails] HTTP Get Request

  - by Karl

  I've been trying to get Rails to play with the new Facebook Graph API. After I get the authorization "code", I need to send another request which returns the access token in JSON form. It seems to work fine, however I want to fetch the access token JSON without redirecting the user. I'm attempting to use Net::HTTP.get, but I'm not sure how to use it to get a request body, or even if it's the right thing to use to begin with. Can anyone give an example of performing an HTTP GET?

• Is there a reliable way to activate / set focus to a window using C#?

  - by gtaborga

  Hey everyone, I'm trying to find a reliable way to activate / set focus a window using C#. Currently I'm attempting to achieve this using the following Windows API calls: SetActiveWindow(handle); SwitchToThisWindow(handle, true); Previously I also had ShowWindow(handle, SW_SHOWMAXIMIZED); executing before the other 2, but removed it because it was causing strange behavior. The problem I'm having with my current implementation is that occasionally the focus will not be set correctly. The window will become visible but the top part of it will still appear grayed out as if it wasn't in focus. Is there a way to reliably do this which works 100% of the time, or is the inconsistent behavior a side-effect I can't escape? Please let me know if you have any suggestions or implementations that always work. Thank you for your time.

• Does .NET have a linker?

  - by Water Cooler v2

  From Jon Skeet's blog: What does the following comment mean? // The line below only works when linked rather than // referenced, as otherwise you need a cast. // The compiler treats it as if it both takes and // returns a dynamic value. string value = com.MakeMeDynamic(10); I understand what referencing an assembly is. You may reference it when compiling the program files either using the /ref: switch at the command line or you may add a statically reference to the assembly in Visual Studio. But how do you link to an assembly in .NET? Does he mean, load the assembly using Reflection (Assembly.LoadFile())? Or, the Win32 API LoadLibrary()? Or, does .NET have a linker that I have never heard of?

• Google Calendar title displayed incorrectly

  - by Don

  Hi, I'm creating 2 Google calendars via the Java client API using the following Groovy method: private CalendarEntry createGoogleCalendar(User user) throws ServiceException { new CalendarEntry().with {calendar -> title = new PlainTextConstruct(user.email) summary = new PlainTextConstruct("Collection calendar for $user.email") timeZone = new TimeZoneProperty("America/Montreal") hidden = HiddenProperty.FALSE def savedCalendar = googleCalendar.insert(CALENDAR_URL, calendar) log.debug "Created calendar with title '$savedCalendar.title.plainText' for '$user.email'" return savedCalendar } } The logs show: CalendarService - Created calendar with title '[email protected]' for '[email protected]' CalendarService - Created calendar with title '[email protected]' for '[email protected]' so it appears that all is well. However when I look at the 1st calendar on the Google website, the title is shown as [email protected], though the summary is correctly shown as Collection calendar for [email protected]. Strangely, the title and summary are both shown correctly tor the 2nd calendar. This only started happening today, and I'm pretty sure the relevant code has not changed. I'm totally stumped....

• playing incoming video stream

  - by mawia

  Hi! all, I am writing an application which is a kinda video streamer.The client is receiving a video stream using udp socket.Now as I am receiving the stream I want to play it simultaneous.It is different from playing local video file lying in your hard disk in which case it can be as simple as running the file using system("vlc filename").But here many issues are involved like there can be delay in receiving and player will have to wait for the incoming data.I have come to know about using vlc to run a video stream.Can you please elaborate the step for playing the stream using vlc.I am implementing my application in c++. EDIT: Can somebody give me some idea regarding VLC API which can be used to stream a given video to particular destination and receive that stream at other end play it. with regards, Mawia

• facebook extended access token login

  - by Pota Onasys

  I have the following code: $facebook = new Facebook(array( 'appId' => ID, 'secret' => SECRET, 'cookie' => true)); $fb_uid = $facebook->getUser(); if($fb_uid) { // check if person with fb_uid as facebook id in database, // if so log them in. If not, register them. $fb_user = $facebook->api('/' . $fb_uid); I then get their email address using $fb_user['email'] and facebook_id and store in the database as a means to log them in the future Sometimes $fb_uid returns false even though the person is logged in using facebook ... I think it is because the access token expires. how can I change this code to incorporate the extended access token to log in the user to my site? offline access token is deprecated, so I need to use the extended access token.

• Inconsistency in java.util.concurrent.Future?

  - by loganj

  For the sake of argument, let's say I'm implementing Future for a task which is not cancelable. The Java 6 API doc says: After [cancel()] returns, subsequent calls to isDone() will always return true. [cancel()] returns false if the task could not be cancelled, typically because it has already completed normally It also says: [isDone()] returns true if this task completed. But what if my cancellation fails not because the task is already completed, but because it simply cannot be cancelled? Is there a way out of this contradiction (other than making my uncancelable task cancelable and sidestepping it altogether)?

• Linux, C++ audio capturing (just microphone) library

  - by TheOm3ga

  I'm developing a musical game, it's like a singstar but instead of singing, you have to play the recorder. It's called oFlute, and it's still in early development stage. In the game, I capture the microphone input, then run a simple FFT analysis and compare the results to typical recorder's frequencies, thus getting the played note. At the beginning, the audio library I was using was RtAudio, but I don't remember why I switched to PortAudio, which is what I'm currently using. The problem is that, from time to time, either it crashes randomly or stops capturing, like if there were no sound coming from the microphone. My question is, what's the best option to capture microphone input on Linux? I just need to open, read, and close a flow of bytes from the microphone. I've been reading this guide, and (un)surprisingly it says: I don't think that PortAudio is very good API for Unix-like operating systems. So, what do you recommend me?

• data structure for counting frequencies in a database table-like format

  - by user373312

  i was wondering if there is a data structure optimized to count frequencies against data that is stored in a database table-like format. for example, the data comes in a (comma) delimited format below. col1, col2, col3 x, a, green x, b, blue ... y, c, green now i simply want to count the frequency of col1=x or col1=x and col2=green. i have been storing the data in a database table, but in my profiling and from empirical observation, database connection is the bottle-neck. i have tried using in-memory database solutions too, and that works quite well; the only problem is memory requirements and quirky init/destroy calls. also, i work mainly with java, but have experience with .net, and was wondering if there was any api to work with "tabular" data in a linq way using java. any help is appreciated.

• Can a flex app (or a portion of a flex app) be made transparent to mouse clicks?

  - by Sam Jones

  I need to superimpose my Flex app above a plain HTML control on a web page, and be able to click through the Flex app to interact with the HTML control. Is there any way to do this? No permutation of mouseEnabled="false" or mouseChildren="false" seems to have the desired effect. Context: trying to integrate Google Earth API (JavaScript/HTML) with my flex app. I am leaving a portion of the flex app transparent and empty, and positioning the Google Earth widget just below that point in the z-index. Google Earth has to be behind flex, because there are some Flex controls periodically displayed in that space.

• How to fetch, display Amazon Marketplace listings by item?

  - by Matt G.

  Hi all, My question pretty much says it all: I'm looking for a way to display Amazon Marketplace listings based on an item lookup. Example: If I do a call to ItemLookup with an ASIN of 0590353403 (Harry Potter and the Sorcerer's Stone), I'm looking for a result set of perhaps the top ten new or used Marketplace listings, preferably with seller information attached. I apologize if this is clearly documented somewhere, but I have been looking all through the Amazon API docs and on Google to no avail. StackOverflow doesn't seem to have any Related Questions that match what I'm asking, either. Thanks in advance!

• Detect movie being played (Windows)

  - by modosansreves

  Watching a movie is quite a different user activity. User doesn't touch neither mouse nor keyboard. Yet he 'actively' uses the computer. Thus, screensaver shouldn't run, indexing should be performed with care etc. On the other side, playing video requires either using direct write to video memory, or DirectShow, or some other API. This may be the key to the answer. What is the Dead Simple Way to determine that a video is being played?

• "Use windows xp style dpi scaling" disables automatic auto-hide of taskbar on W7. Workaround?

  - by Pelle

  We noticed that on W7 with DPI set to 125% or to 100% with ("Use windows xp style dpi scaling") turned off, our fullscreen mode (which sets the client rect of our window = desktop rect of the main monitor) no longer hides the task bar like it does for other settings. (The setting can be found in the Control Panel\Appearance and Personalization\Display section after clicking on the "Set custom text size (DPI)" link) I found the following interesting article: http://www.mathies.com/weblog/?p=908 So I set out to try to work around the bug in other means than manually hiding/restoring the taskbar visibility but so far I've failed and currently believe it's a bug in W7 (and possibly vista). The following applications also fail to work properly in fullscreen mode (the taskbar is still visible): * Microsoft Visual Studio 2008 * Microsoft Word 2007 * Adobe Reader 9.1.3 These apps work (probably by hiding the task bar through the WIN32 API): * Powerpoint Slide Show I also tried creating a brand new MFC-based app and use its "SetFullScreenMode()" functionality but it fails in the same way as all other apps on the list. Does anyone know of a workaround? Thanks, Per
