  • Why is it inserting 0's instead of blank spaces into my DB using php?

    - by zeckdude
    I have an insert: $sql = 'INSERT into orders SET fax_int_prefix = "'.$_SESSION['fax_int_prefix'].'", fax_prefix = "'.$_SESSION['fax_prefix'].'", fax_first = "'.$_SESSION['fax_first'].'", fax_last = "'.$_SESSION['fax_last']; The value of all of these fields is that they are blank right before the insert. Here is an example of one of them I echo'd out just before the insert: $_SESSION[fax_prefix] = For some reason it inserts the integer 0, instead of a blank value or null, as it should. Why is it inserting 0's instead of blank spaces into my DB?

  • In Rails models; for symbols get automatically converted to YAML when saving to DB. What is the corr

    - by Ram
    In my model example Game, has a status column. But I usually set status by using symbols. Example self.status = :active MATCH_STATUS = { :betting_on => "Betting is on", :home_team_won => "Home team has won", :visiting_team_won => "Visiting team has one", :game_tie => "Game is tied" }.freeze def viewable_status MATCH_STATUS[self.status] end I use the above Map to switch between viewable status and viceversa. However when the data gets saved to db, ActiveRecord appends "--- " to each status. So when I retrieve back the status is screwed. What should be the correct approach?

Any idea why?

  • Generating a twitter OAuth access key - the semi-manual way

    - by Piet
    [UPDATE] Apparently someone at Twitter was listening, or I’m going senile/blind. Let’s call it a combination of both. Instead of following all the steps below, you could just login with the Twitter account you want to use on http://dev.twitter.com, register your application and then click ‘Edit Details’ on the application overview page at http://dev.twitter.com/apps. Next click the ‘Application detail’ button on the right, followed by the ‘My Access Token’ button in order to get your Access Token and Access Token Secret. This makes the old post below rather obsolete. Clearly a case of me thinking everything is a nail and ruby is a hammer (don’t they usually say this about java coders?) [ORIGINAL POST] OAuth is great! OAuth allows your application to use your user’s data without the need to ask for their password. So Twitter made the API much safer for their and your users. Hurray! Free pizza for everyone! Unless of course you’re using the Twitter API for your own needs like running your own bot and don’t need access to other user’s data. In such cases a simple username/password combination is more than enough. I can understand however that the Twitter guys don’t really care that much about these exceptions(?). Most such uses for the API are probably rather spammy in nature. !!! If you have a twitter app that uses the API to access external user’s data: look for another solution. This solution is ONLY meant when you ONLY need access to your own account(s) through the API. Other Solutions Mr Dallas Devries posted a solution here which involves requesting and scraping a one-time PIN. But: I like to minimize the amount of calls I make to twitter’s API or pages to lessen my chances of meeting the fail whale. Also, as soon as the pin isn’t included in a div called ‘oauth_pin’ anymore, this will fail. However, mr Devries’ post was a starting point for my solution, so I’m much obliged to him posting his findings. Authenticating with the Twitter API: old vs new Acessing The Twitter API the old way: require ‘twitter’ httpauth = Twitter::HTTPAuth.new('my_account','my_secret_password') client = Twitter::Base.new(httpauth) client.update(‘Hurray!’) The OAuth way: require 'twitter' oauth = Twitter::OAuth.new('ve4whatafuzzksaMQKjoI', 'KliketyklikspQ6qYALcuNandsomemored8pQ6qYALIG7mbEQY') oauth.authorize_from_access('123-owhfmeyAgfozdyt5hDeprSevsWmPo5rVeroGfsthis', 'fGiinCdqtehMeehiddenymDeAsasaawgGeryye8amh') client = Twitter::Base.new(oauth) client.update(‘Hurray!’) In the above case, ve4whatafuzzksaMQKjoI is the ‘consumer key’ (sometimes also referred to as ‘consumer token’) and KliketyklikspQ6qYALcuNandsomemored8pQ6qYALIG7mbEQY is the ‘consumer secret’. You’ll get these from Twitter when you register your app. 123-owhfmeyAgfozdyt5hDeprSevsWmPo5rVeroGfsthis is the ‘access token’ and fGiinCdqtehMeehiddenymDeAsasaawgGeryye8amh is the ‘access secret’. This combination gives the registered application access to your account. I’ll show you how to obtain these by following the steps below. (Basically you’ll need a bunch of keys and you’ll have to jump a bit through hoops to obtain them for your server/bot. ) How to get these keys 1. Surf to the twitter apps registration page go to http://dev.twitter.com/apps to register your app. Login with your twitter account. 2. Register your application Enter something for Application name, Description, website,… as I said: they make you jump through hoops. If you plan on using the API to post tweets, Your application name and website will be used in the ‘5 minutes ago via…’ line below your tweet. You could use the this to point to a page with info about your bot, or maybe it’s useful for SEO purposes. For application type I choose ‘browser’ and entered http://www.hadermann.be/callback as a ‘Callback URL’. This url returns a 404 error, which is ideal because after giving our account access to our ‘application’ (step 6), it will redirect to this url with an ‘oauth_token’ and ‘oauth_verifier’ in the url. We need to get these from the url. It doesn’t really matter what you enter here though, you could leave it blank because you need to explicitely specify it when generating a request token. You probably want read&write access so set this at ‘Default Access type’. 3. Get your consumer key and consumer secret On the next page, copy/paste your ‘consumer key’ and ‘consumer secret’. You’ll need these later on. You also need these as part of the authentication in your script later on: oauth = Twitter::OAuth.new([consumer key], [consumer secret]) 4. Obtain your request token run the following in IRB to obtain your ‘request token’ Replace my fake consumer key and consumer secret with the one you obtained in step 3. And use something else instead http://www.hadermann.be/callback: although this will only give a 404, you shouldn’t trust me. irb(main):001:0> require 'oauth' irb(main):002:0> c = OAuth::Consumer.new('ve4whatafuzzksaMQKjoI', 'KliketyklikspQ6qYALcuNandsomemored8pQ6qYALIG7mbEQY', {:site => 'http://twitter.com'}) irb(main):003:0> request_token = c.get_request_token(:oauth_callback => 'http://www.hadermann.be/callback') irb(main):004:0> request_token.token => "UrperqaukeWsWt3IAlfbxzyBUFpwWIcWkHP94QH2C1" This (UrperqaukeWsWt3IAlfbxzyBUFpwWIcWkHP94QH2C1) is the request token: Copy/paste this token, you will need this next. 5. Authorize your application surf to https://api.twitter.com/oauth/authorize?oauth_token=[the above token], for example: https://api.twitter.com/oauth/authorize?oauth_token=UrperqaukeWsWt3IAlfbxzyBUFpwWIcWkHP94QH2C1 This will bring you to the ‘An application would like to connect to your account’- screen on Twitter where you can grant access to the app you just registered. If you aren’t still logged in, you need to login first. Click ‘Allow’. Unless you don’t trust yourself. 6. Get your oauth_verifier from the redirected url Your browser will be redirected to your callback url, with an oauth_token and oauth_verifier parameter appended. You’ll need the oauth_verifier. In my case the browser redirected to: http://www.hadermann.be/callback?oauth_token=UrperqaukeWsWt3IAlfbxzyBUFpwWIcWkHP94QH2C1&oauth_verifier=waoOhKo8orpaqvQe6rVi5fti4ejr8hPeZrTewyeag Which returned a 404, giving me the chance to copy/paste my oauth_verifier: waoOhKo8orpaqvQe6rVi5fti4ejr8hPeZrTewyeag 7. Request an access token Back to irb, use the oauth_verifier to request an access token, as follows: irb(main):005:0> at = request_token.get_access_token(:oauth_verifier => 'waoOhKo8orpaqvQe6rVi5fti4ejr8hPeZrTewyeag') irb(main):006:0> at.params[:oauth_token] => "123-owhfmeyAgfozdyt5hDeprSevsWmPo5rVeroGfsthis" irb(main):007:0> at.params[:oauth_token_secret] => "fGiinCdqtehMeehiddenymDeAsasaawgGeryye8amh" We’re there! 123-owhfmeyAgfozdyt5hDeprSevsWmPo5rVeroGfsthis is the access token. fGiinCdqtehMeehiddenymDeAsasaawgGeryye8amh is the access secret. Try it! Try the following to post an update: require 'twitter' oauth = Twitter::OAuth.new('ve4whatafuzzksaMQKjoI', 'KliketyklikspQ6qYALcuNandsomemored8pQ6qYALIG7mbEQY') oauth.authorize_from_access('123-owhfmeyAgfozdyt5hDeprSevsWmPo5rVeroGfsthis', 'fGiinCdqtehMeehiddenymDeAsasaawgGeryye8amh') client = Twitter::Base.new(oauth) client.update(‘Cowabunga!’) Now you can go to your twitter page and delete the tweet if you want to.

  • Errors trying to run MongoDB

    - by SomeKittens
    I'm running Ubuntu Server 12.04 (32 bit) on an old (1998) computer.

  • How can I put multiple markers on Google maps with Javascript API v3?

    - by Doe
    Hi, I'd like to know how to put multiple markers for Google Maps using Javascript API v3. I tried the solution posted here: http://stackoverflow.com/questions/1621991/multiple-markers-in-googe-maps-api-v3-that-link-to-different-pages-when-clicked but it does not work for me for some reason. var directionDisplay; function initialize() { var myOptions = { zoom: 9, center: new google.maps.LatLng(40.81940575,-73.95647955), mapTypeId: google.maps.MapTypeId.TERRAIN } var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); setMarkers(map, properties); var properties = [ ['106 Ft Washington Avenue',40.8388485,-73.9436015,'Mjg4'], ]; function setMarkers(map, buildings) { var image = new google.maps.MarkerImage('map_marker.png', new google.maps.Size(19,32), new google.maps.Point(0,0), new google.maps.Point(10,32)); var shadow = new google.maps.MarkerImage('map_marker_shadow.png', new google.maps.Size(28,32), new google.maps.Point(0,0), new google.maps.Point(10,32)); var bounds = new google.maps.LatLngBounds; for (var i in buildings) { var myLatLng = new google.maps.LatLng(buildings[i][1], buildings[i][2]); bounds.extend(myLatLng); var marker = new google.maps.Marker({ position: myLatLng, map: map, shadow: shadow, icon: image, title: buildings[i][0] }); google.maps.event.addListener(marker, 'click', function() { window.location = ('detail?b=' + buildings[i][3]); }); } map.fitBounds(bounds); } } </script> Could anyone kindly explain why this doesn't work for me?

  • Java RegEx API "Look-behind group does not have an obvious maximum length near index ..."

    - by Foo Inc
    Hello, I'm on to some SQL where clause parsing and designed a working RegEx to find a column outside string literals using "Rad Software Regular Expression Desginer" which is using the .NET API. To make sure the designed RegEx works with Java too, I tested it by using the API of course (1.5 and 1.6). But guess what, it won't work. I got the message "Look-behind group does not have an obvious maximum length near index 28". The string that I'm trying to get parsed is Column_1='test''the''stuff''all''day''long' AND Column_2='000' AND TheVeryColumnIWantToFind = 'Column_1=''test''''the''''stuff''''all''''day''''long'' AND Column_2=''000'' AND TheVeryColumnIWantToFind = '' TheVeryColumnIWantToFind = '' AND (Column_3 is null or Column_3 = ''Not interesting'') AND ''1'' = ''1''' AND (Column_3 is null or Column_3 = 'Still not interesting') AND '1' = '1' As you may have guessed, I tried to create some kind of worst case to ensure the RegEx won't fail on more complicated SQL where clauses. The RegEx itself looks like this (?i:(?<!=\s*'(?:[^']|(?:''))*)((?<=\s*)TheVeryColumnIWantToFind(?=(?:\s+|=)))) I'm not sure if there is a more elegant RegEx (there'll most likely be one), but that's not important right now as it does the trick. To explain the RegEx in a few words: If it finds the column I'm after, it does a negative look-behind to figure out if the column name is used in a string literal. If so, it won't match. If not, it'll match. Back to the question. As I mentioned before, it won't work with Java. What will work and result in what I want? I found out, that Java does not seem to support unlimited look-behinds but still I couldn't get it to work. Isn't it right that a look-behind is always putting a limit up on itself from the search offset to the current search position? So it would result in something like "position - offset"?

  • Is Rails Metal (& Rack) a good way to implement a high traffic web service api?

    - by Greg
    I am working on a very typical web application. The main component of the user experience is a widget that a site owner would install on their front page. Every time their front page loads, the widget talks to our server and displays some of the data that returns. So there are two components to this web application: the front end UI that the site owner uses to configure their widget the back end component that responds to the widget's web api call Previously we had all of this running in PHP. Now we are experimenting with Rails, which is fantastic for #1 (the front end UI). The question is how to do #2, the back serving of widget information, efficiently. Obviously this is much higher load than the front end, since it is called every time the front page loads on one of our clients' websites. I can see two obvious approaches: A. Parallel Stack: Set up a parallel stack that uses something other than rails (e.g. our old PHP-based approach) but accesses the same database as the front end B. Rails Metal: Use Rails Metal/Rack to bypass the Rails routing mechanism, but keep the api call responder within the Rails app My main question: Is Rails/Metal a reasonable approach for something like this? But also... Will the overhead of loading the Rails environment still be too heavy? Is there a way to get even closer to the metal with Rails, bypassing most of the environment? Will Rails/Metal performance approach the perf of a similar task on straight PHP (just looking for ballpark here)? And... Is there a 'C' option that would be much better than both A and B? That is, something before going to the lengths of C code compiled to binary and installed as an nginx or apache module? Thanks in advance for any insights.

  • unable to send email using REST API build in php?

    - by Pushpendra Kuntal
    i am designing REST API in php. I want to send a page to send email. This is my code to send email: $app->get('/sendemail', function () { <?php require_once "Mail.php"; $from = "Sandra Sender <[email protected]>"; $to = "Ramona Recipient <[email protected]>"; $subject = "Hi!"; $body = "Hi,\n\nHey Kuntal, you done it..."; $host = "my host"; $username = "myuserid"; $password = "password"; $headers = array ('From' => $from, 'To' => $to, 'Subject' => $subject); $smtp = Mail::factory('smtp', array ('host' => $host, 'auth' => true, 'username' => $username, 'password' => $password)); $mail = $smtp->send($to, $headers, $body); if (PEAR::isError($mail)) { echo("<p>" . $mail->getMessage() . "</p>"); } else { echo("<p>Message successfully sent!</p>"); } ?> }); My code of sending email is working if i check this into my separate file. But this code is not working in API. please suggest me what should i do for this?

  • what's the best way, using the TFS API, to add a label to a file?

    - by jcollum
    I'd like to add a label to a set of files using the TFS API. My code looks like this: VersionControlLabel label = new VersionControlLabel(this.vcServer, this.label, this.vcServer.AuthenticatedUser, this.labelScopeDirectory, this.labelComment); List<LabelItemSpec> labelSpecs = new List<LabelItemSpec>(); // iterate files and versions foreach (var fileAndVersion in this.filesAndVersions) { VersionSpec vs = null; Item i = null; // i have no idea why the itemspec is needed instead of the item and version... ItemSpec iSpec = new ItemSpec("{0}/{1}".FormatString(this.source, fileAndVersion.Key), RecursionType.None); GetItemAndVersionSpec(fileAndVersion.Key, fileAndVersion.Value, out vs, out i); labelSpecs.Add(new LabelItemSpec(iSpec, vs, false)); } this.vcServer.CreateLabel(label, labelSpecs.ToArray(), LabelChildOption.Merge); (there are some extension methods in there... this is all largely lifted from this blog post) The thing that concerns me is things like this in the MSDN docs: This enumeration supports the .NET Framework infrastructure and is not intended to be used directly from your code. So MSDN is telling me not to use that enumeration (LabelChildOption), which is afaik the only way to create a label and add it to a file. Is there a better way? Is this sort of a "grey" area in the TFS API?

  • Crystal reports 11 RDC (COM API) displays printer dialog even when I tell it not to prompt

    - by bdonlan
    I'm using Crystal Reports 11's RDC (COM) API to print. My code looks like this: HRESULT res = m_Report->SelectPrinter(b_driver, b_device, b_port); if (FAILED(res)) return res; // For these calls, the #import wrapper throws on error m_Report->PutPrinterDuplex(dmDuplex); m_Report->PutPaperSize(dmPaperSize); m_Report->PutPaperSource((CRPaperSource)pdlg->GetDevMode()->dmDefaultSource); if (m_Report->GetPaperOrientation() == crDefaultPaperOrientation) m_Report->PutPaperOrientation(crPortrait); VARIANT vfalse; VariantInit(&vfalse); vfalse.vt=VT_BOOL; vfalse.boolVal=0; res = m_Report->PrintOut(vfalse); However, at the end of all this, crystal reports still shows its own printer selection dialog - but only for some reports, it seems. Why does crystal reports show a print dialog even when I pass false for promptUser? And how, then, can I suppress crystal reports' internal printer selection dialog and force it to use my values? Edit: Whoops, CR11, not CR9. Some further information: The reports that work properly (ie, do not show the print dialog) are generated internally using the RDC API; we create a new report object, import subreports into it, then print the result. No problem there. The reports that do not work properly (ie, force the print dialog to open) have been created with a previous version of crystal reports; however, opening and saving the report does not seem to help. Sample reports in the Crystal Reports installation directory show the same problem. I tried reproducing with VBScript; however, the result was that nothing was printed at all (no dialog, no nothing): Set app = CreateObject("CrystalRuntime.Application.11") Set report = app.OpenReport("C:\Program Files\Business Objects\Crystal Reports 11.5\Samples\en\Reports\General Business\Inventory Crosstab.rpt") report.PrintOut(True) rem Testing with a True parameter to force a print dialog - but no printout and nothing appears (no error either though)

  • RESTful API design question - how should one allow users to create new resource instances?

    - by Tamás
    I'm working in a research group where we intend to publish implementations of some of the algorithms we develop on the web via a RESTful API. Most of these algorithms work on small to medium size datasets, and in many cases, a user of our services might want to run multiple queries (with different parameters) on the same dataset, so for me it seems reasonable to allow users to upload their datasets in advance and refer to them in their queries later. In this sense, a dataset could be a resource in my API, and an algorithm could be another. My question is: how should I let the users upload their own datasets? I cannot simply let users upload their data to /dataset/dataset_id as letting the users invent their own dataset_ids might result in ID collision and users overwriting each other's datasets by accident. (I believe one of the most frequently used dataset ID would be test). I think an ideal way would be to have a dedicated URL (like /dataset/upload) where users can POST their datasets and the response would contain a unique ID under which the dataset was stored, but I'm not sure that it does not violate the basic principles of REST. What is the preferred way of dealing with such scenarios?

  • Looking for Recommendations on Version Control System with Intuitive (.NET) API?

    - by John L.
    I'm working on a project which generates (composite) Microsoft Word documents which are comprised of one or more child documents. There are tens of thousands of permutations of the composite documents. Far too many for users to easily manage. Users will need to view/edit the child documents through the app which hides all of the nasty implementation details. A requirement of the system is that the child documents must be version controlled. That is what has been tripping me up. I've been torn between using an off-the-shelf solution or rolling my own. At a minimum, the system needs to support get latest, get specific version, add new, rename and possibly delete. I’ve whiteboarded it enough to realize it won’t be a trivial task to create my own. As far as commercial systems I have VSS and TFS at my disposal. I've played with the TFS API some, but it isn’t as intuitive or well documented as I had hoped. I'm not averse to an open source solution (e.g. SVN), but I have less familiarity with them. Which approach or tool would you recommend? Why? Do you have any links to API documentation you would recommend? Environment: C#, VS2008, SQL Server 2005/2008, low volume (a few hundred operations per day)

  • Can any linux API or tool watch for any change in any folder below e.g. /SharedRoot or do I have to

    - by Simon B.
    I have a folder with ~10 000 subfolders. Can any linux API or tool watch for any change in any folder below e.g. /SharedRoot or do I have to setup inotify for each folder? (i.e. I loose if I want to do this for 10k+ folders). I guess yes, since I've already seen examples of this inefficient method, for instance http://twistedmatrix.com/trac/browser/trunk/twisted/internet/inotify.py?rev=28866#L345 My problem: I need to keep folders time-sorted with most recently active "project" up top. When a file changes, each folder above that file should update its last-modified timestamp to match the file. Delays are ok. Opening a file (typically MS Excel) and closing again, its file date can jump up and then down again. For this reason I need to wait until after a file is closed, then queue the folder of that file for checking, and only a while later do I go and look for the newest file in its folder, since the filedate of the triggering file could already be back-dated to its original timestamp by Excel or similar programs. Also in case several files from same folder are used/created, it makes sense to buffer timestamping of that folders' parents to at least get a bunch of updates collapsed into one delayed update. I'm looking for a linux solution. I have some code that can be run on a windows server, most of the queing functionality is here: http://github.com/sesam/FolderdateFollowsFiles/blob/master/FolderdateFollowsFiles/Follower.vb Available API:s The relative of inotify on windows, ReadDirectoryChangesW, can watch a folder and its whole subtree; see bWatchSubtree on http://msdn.microsoft.com/en-us/library/aa365465(VS.85).aspx Samba? Patching samba source is a possibility, but perhaps there are already hooks available? Other possibilities, like client side (various windows versions) and spying on file activities in order to update folders recursively?

  • Getting all objects with a certain element inside a collection of strings with criteria API.

    - by Jens Jansson
    Hey. I'm trying to build a Hibernate Criteria query to find entities that have a specific element inside a collection. We can take as an example a Book -object that looks like this: public class Book { private Long id; private String title; private Set<String> authors = new HashSet<String>(); } The entity is mapped like this: <class name="Book" table="Book"> <id name="id" column="BOOK_ID"> <generator class="native"/> </id> <property name="title"/> <set name="authors" table="Book_Authors"> <key column="BOOK_ID"/> <element type="string" column="AUTHORS"/> </set> </class> Now I would like to find out which books are written by Matt. With pure SQL I can do a query like this: String author = "Matt"; String query = "SELECT * FROM Book " + "WHERE BOOK_ID IN " + "(SELECT BOOK_ID FROM Book_Authors " + "WHERE authors = :author )"; List<Book> result = session.createSQLQuery(query) .addEntity(Book.class) .setParameter("author", author) .list(); This works all good and well, and I get out all books that Matt has been a part of writing. The project I work in, however, uses the Criteria API instead of raw SQL, and I haven't found a way to express the same query in that form. I've taken a look on the Restrictions API and the closest I've found is Restions.in(propertyName, collection) but that works the other way around (one value in object, many values to match against). Any ideas?

  • SpeechRecognizer causes ANR... I need help with Android speech API.

    - by Dondo Chaka
    I'm trying to use Android's speech recognition package to record user speech and translate it to text. Unfortunately, when I attempt initiate listening, I get an ANR error that doesn't point to anything specific. As the SpeechRecognizer API indicates, a RuntimeException is thrown if you attempt to call it from the main thread. This would make me wonder if the processing was just too demanding... but I know that other applications use the Android API for this purpose and it is typically pretty snappy. java.lang.RuntimeException: SpeechRecognizer should be used only from the application's main thread Here is a (trimmed) sample of the code I'm trying to call from my service. Is this the proper approach? Thanks for taking the time to help. This has been a hurdle I haven't been able to get over yet. Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, "com.domain.app"); SpeechRecognizer recognizer = SpeechRecognizer .createSpeechRecognizer(this.getApplicationContext()); RecognitionListener listener = new RecognitionListener() { @Override public void onResults(Bundle results) { ArrayList<String> voiceResults = results .getStringArrayList(RecognizerIntent.EXTRA_RESULTS); if (voiceResults == null) { Log.e(getString(R.string.log_label), "No voice results"); } else { Log.d(getString(R.string.log_label), "Printing matches: "); for (String match : voiceResults) { Log.d(getString(R.string.log_label), match); } } } @Override public void onReadyForSpeech(Bundle params) { Log.d(getString(R.string.log_label), "Ready for speech"); } @Override public void onError(int error) { Log.d(getString(R.string.log_label), "Error listening for speech: " + error); } @Override public void onBeginningOfSpeech() { Log.d(getString(R.string.log_label), "Speech starting"); } }; recognizer.setRecognitionListener(listener); recognizer.startListening(intent);

  • Difficulty porting raw PCM output code from Java to Android AudioTrack API.

    - by IndigoParadox
    I'm attempting to port an application that plays chiptunes (NSF, SPC, etc) music files from Java SE to Android. The Android API seems to lack the javax multimedia classes that this application uses to output raw PCM audio. The closest analog I've found in the API is AudioTrack and so I've been wrestling with that. However, when I try to run one of my sample music files through my port-in-progress, all I get back is static. My suspicion is that it's the AudioTrack I've setup which is at fault. I've tried various different constructors but it all just outputs static in the end. The DataLine setup in the original code is something like: AudioFormat audioFormat = new AudioFormat( AudioFormat.Encoding.PCM_SIGNED, 44100, 16, 2, 4, 44100, true ); DataLine.Info lineInfo = new DataLine.Info( SourceDataLine.class, audioFormat ); DataLine line = (SourceDataLine)AudioSystem.getLine( lineInfo ); The constructor I'm using right now is: AudioTrack = new AudioTrack( AudioManager.STREAM_MUSIC, 44100, AudioFormat.CHANNEL_CONFIGURATION_STEREO, AudioFormat.ENCODING_PCM_16BIT, AudioTrack.getMinBufferSize( 44100, AudioFormat.CHANNEL_CONFIGURATION_STEREO, AudioFormat.ENCODING_PCM_16BIT ), AudioTrack.MODE_STREAM ); I've replaced constants and variables in those so they make sense as concisely as possible, but my basic question is if there are any obvious problems in the assumptions I made when going from one format to the other.

  • How to enumerate word document using office interop API?

    - by Shekhar
    Hello everyone, I want to traverse through all the elements of an word document one by one and according to type of element (header, sentence, table,image,textbox, shape, etc.) I want to process that element. I tried to search any enumerator or object which can represent elements of document in office interop API but failed to find any. API offers sentences, paragraphs, shapes collections but doesnt provide generic object which can point to next element. For example : <header of document> <plain text sentences> <table with many rows,columns> <text box> <image> <footer> (Please imagine it as a word document) So, now I want some enumerator which will first give me <header of document>, then on next iteration give me <plain text sentences>, then <table with many rows,columns> and so on. Does anyone knows how we can achieve this? Is it possible? I am using C#, visual studio 2005 and Word 2003. Thanks a lot

  • Is there an x86 or x64 emulator that passes system calls back to the Windows API?

    - by Chris Lomont
    I want to emulate windows programs (not VM, true emulation) under windows. This would require the emulator to make calls back to the system APIs, but the program itself would be emulated. The reason is I want to change the opcode formats for research purposes. The process should be: Take existing program. Disassemble and then reassemble with my new opcode formats. Put the new format into the PE with a stub calling the emulator and passing the new code. The emulator would have to pass system calls from the emulated side back to windows API calls. I can do all these steps, except I need an open source emulator with the ability to pass the API calls out. I could try Bochs or QEMU, but I think I'd have to add in the system calls, which I could do if needed. I wonder if there is already something closer to what I need. I know I would have to change the instruction decoding in the emulator to match my new formats, but that is a given. Thanks.

  • Where can I find a powerful, standards compliant, web-based interactive org chart API?

    - by Adam Soltys
    Hi, I'm looking to build an interactive web-based org chart for a large organization. I somewhat like the interface at ancestry.com where you can hover over people and pan/zoom around and click on different nodes to make them the root. Ideally, I'd like it if people could belong to multiple organizational entities like committees, working groups, etc. In other words the API should support graphs in general, not just trees. I'd like to be able to visually explode each organizational substructure into substituents by clicking on it, with a nice animation of the employees ballooning or spilling out so you can really interactively drill down through the organization. I found http://code.google.com/apis/visualization/documentation/gallery/orgchart.html but it looks a bit rudimentary. I know there are desktop tools like OrgPlus and Visio that can build static charts but I'm really looking for a free, web-based API with open standards-based output like SVG or HTML5 Canvas elements rather than Flash or some proprietary output. Something I can embed into a custom web application and style myself. Something interactive.

  • SQL Server 2008 Unique Problem for bring DB Online...

    - by Nai
    This is my error I am facing TITLE: Microsoft.SqlServer.Smo Set offline failed for Database 'Go3D_Retailer ------------------------------ ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo) Unable to open the physical file "E:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\ftrow_Go3D_catalog.ndf". Operating system error 2: "2(failed to retrieve text for this error. Reason: 15105)". Database 'Go3D_Retailer' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details. ALTER DATABASE statement failed. (Microsoft SQL Server, Error: 5120) Background to this error I've been trying to move my destination logshipping database to another physical server for analysis purposes. Because I do not have active directory set up, I had to hack my process by using the same username/password for both the source and destination servers to get the process to work. Following that, I used this guy's solution to move the destination database to another server. However, this error occurs when I try to bring the database back online. I don't have an E drive on my server and I have no idea why it's trying to open a file from E drive. I have over a 100gb left on my hard disk so it's definitely not a space issue. This sounds like a bug... Any ideas? I'm running SQL Server 2008 Enterprise edition on Windows Server 2008 R2 64bit

  • Why would the 'show processlist' command speed up normally slow requests to my remote DB? (connected via VPN)

    - by Hakan B.
    I am running a local Django development server that connects to a remote MySQL server via a VPN (IPSec). Request times are awfully slow and I consistently see timeouts. Attempting to diagnose the problem, I logged in to the remote database and ran: show full processlist Immediately, the local server went from idle to working. The page had not yet completely loaded, but progress had been made (debug logs confirm this). When I ran 'show full processlist' several times more in succession, the request completed quickly. I can currently reproduce this - unless I run 'show full processlist' over and over on the remote server, my local request usually times out. Does anyone have any idea why this would happen? I'm running Django 1.3 and OS X 10.7. Note: I realize this may be entirely not be a question with a clear-cut answer and is probably my fault, but it is odd and reproducable, so I hope someone can at least point me the right direction. Thanks in advance.

  • "postgres blocked for more than 120 seconds" - is my db still consistent?

    - by nn4l
    I am using an iscsi volume on an Open-E storage system for several virtual machines running on a XenServer host. Occasionally, when there is a very high disk I/O load on the virtual machines (and therefore also on the storage system), I got this error message on the vm consoles: [2594520.161701] INFO: task kjournald:117 blocked for more than 120 seconds. [2594520.161787] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [2594520.162194] INFO: task flush-202:0:229 blocked for more than 120 seconds. [2594520.162274] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [2594520.162801] INFO: task postgres:1567 blocked for more than 120 seconds. [2594520.162882] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. I understand this error message is caused by the kernel to inform that these processes haven't been run for 120 seconds, most likely because a disk access to the storage system has not yet been processed. But what is the effect on the processes. For example, will the postgres process eventually write its data when the storage system is idle again after a few minutes, so that all data is still consistent? Or will it abort the write, leaving some tables in an inconsistent state? I certainly expect that the former should be the case - if the disk access is slow, postgres (or any other affected process) should just wait as long as it takes. I can live with the application hanging for a few minutes. But if there is a chance for data corruption then any of these errors is really bad news. Please advise what to do here.
