  • Trouble adding video controls to video selected by XML comboBox

    - by user560128
    Hello, it's been a few years since I've touched flash, so perhaps I'm just overlooking something. If anyone could look at the code and offer any suggestions that would be awesome. What's working, I select a video from a combobox that is populated from an XML file, pick the video and it plays. I've been trying to add pause/play, stop, forward and reverse functionality, once I get that to work I also want to add a video scrubber(slider), and previous/next buttons to go to the previous/next video as listed in the xml file. At the moment I have a component button on the stage called playButton, which I'm trying to use for pause/play functionality. Below is my code, the player control is at the very bottom. Thanks. import fl.data.DataProvider; var nc:NetConnection = new NetConnection(); nc.connect(null); var ns:NetStream = new NetStream(nc); var videosXML:XML = new XML(); var loader:URLLoader = new URLLoader(); var request:URLRequest= new URLRequest("xml/videos.xml"); var videos:Array = new Array({label:"Select a Video",data:""}); var client:Object = new Object(); theVideo.attachNetStream(ns); ns.client = client; loader.addEventListener(Event.COMPLETE,loaderOnComplete); loader.load (request); function loaderOnComplete(event:Event):void{ videosXML = new XML(event.target.data); for each (var video:XML in videosXML.video){ videos.push({label:video.name.toString(),data:video.url.toString()}); } moviesCB.dataProvider = new DataProvider(videos); } moviesCB.addEventListener(Event.CHANGE, changeHandler); function changeHandler(event:Event):void { if(ComboBox(event.target).selectedItem.data != ""){ ns.play(ComboBox(event.target).selectedItem.data); } }; client.onMetaData = metadataHandler; function metadataHandler(md:Object):void{ } //player controls playButton.onRelease = function() { ns.pause(); }

  • How to distribute an offline cube for excel

    - by Mike M
    I have the following scenario. A cube created in SSAS 2008. I can connected to this cube via Excel. I can create an offline cube file. I can connect to this offline cube file. Now, say I want to email this excel file along with the cube file so that another user can view it. I run into the problem that the connection path the offline cube is hard coded into the excel file. Its the same problem this person had. http://stackoverflow.com/questions/1253950/opening-offline-cube-from-another-machine Their solution was to just make sure the other user saved the cube in the same directory structure. I don't love that solution. I also came across this idea: http://www.pcreview.co.uk/forums/thread-948974.php I tried that, it errored out, but I am not an Excel VBA programmer and really have no idea if I even put the code in the right place. So anyway, anyone out there have any ideas about who to do this? If the VBA solution is the best, could someone give me some tips on where to actually put that code?

  • Too many open files in one of my java routine.

    - by Irfan Zulfiqar
    I have a multithreaded code that has to generated a set of objects and write them to a file. When I run it I sometime get "Too many open files" message in Exception. I have checked the code to make sure that all the file streams are being closed properly. Here is the stack trace. When I do ulimit -a, open files allowed is set to 1024. We think increasing this number is not a viable option / solution. [java] java.io.FileNotFoundException: /export/event_1_0.dtd (Too many open files) [java] at java.io.FileInputStream.open(Native Method) [java] at java.io.FileInputStream.<init>(FileInputStream.java:106) [java] at java.io.FileInputStream.<init>(FileInputStream.java:66) [java] at sun.net.www.protocol.file.FileURLConnection.connect(FileURLConnection.java:70) [java] at sun.net.www.protocol.file.FileURLConnection.getInputStream(FileURLConnection.java:161) [java] at java.net.URL.openStream(URL.java:1010) Now what we have identified so far by looking closely at the list of open files is that the VM is opening same class file multiple times. /export/BaseEvent.class 236 /export/EventType1BaseEvent.class 60 /export/EventType2BaseEvent.class 48 /export/EventType2.class 30 /export/EventType1.class 14 Where BaseEvent is partent of all the classes and EventType1 ant EventType2 inherits EventType1BaseEvent and EventType2BaseEvent respectively. Why would a class loader load the same class file 200+ times. It seems it is opening up the base class as many time it create any child instance. Is this normal? Can it be handler any other way apart from increasing the number of open files?

  • Can I perform a search on mail server in Java?

    - by twofivesevenzero
    I am trying to perform a search of my gmail using Java. With JavaMail I can do a message by message search like so: Properties props = System.getProperties(); props.setProperty("mail.store.protocol", "imaps"); Session session = Session.getDefaultInstance(props, null); Store store = session.getStore("imaps"); store.connect("imap.gmail.com", "myUsername", "myPassword"); Folder inbox = store.getFolder("Inbox"); inbox.open(Folder.READ_ONLY); SearchTerm term = new SearchTerm() { @Override public boolean match(Message mess) { try { return mess.getContent().toString().toLowerCase().indexOf("boston") != -1; } catch (IOException ex) { Logger.getLogger(JavaMailTest.class.getName()).log(Level.SEVERE, null, ex); } catch (MessagingException ex) { Logger.getLogger(JavaMailTest.class.getName()).log(Level.SEVERE, null, ex); } return false; } }; Message[] searchResults = inbox.search(term); for(Message m:searchResults) System.out.println("MATCHED: " + m.getFrom()[0]); But this requires downloading each message. Of course I can cache all the results, but this becomes a storage concern with large gmail boxes and also would be very slow (I can only imagine how long it would take to search through gigabytes of text...). So my question is, is there a way of searching through mail on the server, a la gmail's search field? Maybe through Microsoft Exchange? Hours of Googling has turned up nothing.

  • Matlab Simulation: Point (symbol) Moving from start point to end point and back

    - by niko
    Hi, I would like to create an animation to demonstrate LDPC coding which is based on Sum-Product Algorithm So far I have created a graph which shows the connections between symbol nodes (left) and parity nodes (right) and would like to animate points travelling from symbol to parity nodes and back. The figure is drawn by executing the following method: function drawVertices(H) hold on; nodesCount = size(H); parityNodesCount = nodesCount(1); symbolNodesCount = nodesCount(2); symbolPoints = zeros(symbolNodesCount, 2); symbolPoints(:, 1) = 0; for i = 0 : symbolNodesCount - 1 ji = symbolNodesCount - i; scatter(0, ji) symbolPoints(i + 1, 2) = ji; end; parityPoints = zeros(parityNodesCount, 2); parityPoints(:, 1) = 10; for i = 0 : parityNodesCount - 1 ji = parityNodesCount - i; y0 = symbolNodesCount/2 - parityNodesCount/2; scatter(10, y0 + ji) parityPoints(i + 1, 2) = y0 + ji; end; axis([-1 11 -1 symbolNodesCount + 2]); axis off %connect vertices d = size(H); for i = 1 : d(1) for j = 1 : d(2) if(H(i, j) == 1) plot([parityPoints(i, 1) symbolPoints(j, 1)], [parityPoints(i, 2) symbolPoints(j, 2)]); end; end; end; So what I would like to do here is to add another method which takes start point (x and y) and end point as arguments and animates a travelling circle (dot) from start to end and back along the displayed lines. I would appreciate if anyone of you could show the solution or suggest any useful tutorial about matlab simulations. Thank you!

  • Asp.Net Login Control very slow initial connection to Non-Trusted AD Domain

    - by Eric Brown - Cal
    ASP.NET Login control is very slow making the initial connection to AD when authenticating to a different domain than the domain the web server is a member of. Problem occurs for the IIS server and when using with the Visual Studio's built in web server. It takes about 30 seconds the first time when attempting to use the control to connect against another domain. There is no trust relationship bewteen the web server's domain and the other domains (attempted connecting to several different domains). Subsequent connections execute quickly until the connection times out. Using Systernals Process Monitor to troubleshoot, there are two OpenQuery operations right before the delay to "C:\WINDOWS\asembly\GAC_MSIL\System.DirectoryServices\2.0.0.0_b03f5f7f11d50a3a\Netapi32.dll with a result NAME NOT FOUND" and right after the 30 second delay the TCP Send and TCP Recieves indicate communication begins with the AD server. Things we have tried: Impersonating an administrator on the web server in the web.config; Granting permissions to the CryptoKeys to the NetworkService and ASPNET; Specifying by IP instead of DNS name; Multiple variations of specifying the name and ldap server with domains and OU's; Local host entries; Looked for ports being blocked (SYN_SENT) with netstat -an. Nslookup resolves all the domains and systems involved correectly. TraceRt shows the Correct routes Any Idea or hints are greately appreicated.

  • Why do I get CA1806 when I catch exception in C++/CLI?

    - by brickner
    I've recently upgraded my project from Visual Studio 2008 to Visual Studio 2010. By enabling Code Analysis and compiling in Release, I'm getting warning CA1806: Do not ignore method results. I've managed to reduce the code that produces the warning to this code: .h file: public ref class Foo { public: void Bar(); }; .cpp file: void Foo::Bar() { try { } catch (const std::exception&) // here I get the warning { } } the warning: CA1806 : Microsoft.Usage : 'Foo::Bar(void)' calls 'Global::__CxxRegisterExceptionObject(void*, void*)' but does not use the HRESULT or error code that the method returns. This could lead to unexpected behavior in error conditions or low-resource situations. Use the result in a conditional statement, assign the result to a variable, or pass it as an argument to another method. If I try to use the exception value or do catch(...) the warning still appears. If I catch managed exceptions instead or compile in Debug I don't get the warning. Why do I get this warning? UPDATE I've decided to open a bug report on Microsoft Connect.

  • How can I use a different id field for one of my CakePHP model associations?

    - by gacrux
    I have an one to many association in which a Thing can have many Statuses defined as below: Status Model: class Status extends AppModel { var $name = 'Status'; var $belongsTo = array( 'Thing' => array( 'className' => 'Thing', 'foreignKey' => 'thing_id', ); } Thing Model: class Thing extends AppModel { var $name = 'Thing'; var $belongsTo = array( // other associations ); var $hasMany = array( 'Status' => array( 'className' => 'Status', 'foreignKey' => 'thing_id', 'dependent' => false, 'order' => 'datetime DESC', 'limit' => '10', ), // other associations ); } This works OK, but I would like Thing to use a different id to connect to Status. E.g. Thing would use 'id' for all of it's other associations but use 'thing_status_id' for it's Status association. How can I best do this?

  • Unable to change URL for .NET reference to dynamic web service

    - by Malvineous
    Hi all, I have a web reference added to a C# .NET project. The URL for the web reference needs to change depending on whether I'm building for a development, staging or production environment. I've set the web service to be dynamic, which supposedly means it takes the URL from my app.config file. When I perform a build it overwrites the app.config with the required file which contains the correct URL (different file for each of dev/staging/production.) I then go into the solution properties and make sure the Settings.settings file is updated with the app.config changes. However when I view the properties for the web service, it is still showing the old URL, despite it being dynamic, and supposed to be reading from my settings file (even after closing and reopening the project/solution.) The app.config and the settings file all have the new URL, but the web reference doesn't notice it has changed. If I do a build it ignores the URL in the settings file and tries to connect to the last URL manually typed into the web reference's properties. Typing a URL into these properties correctly updates the app.config and .settings files, so the link is definitely there. I'm a bit new to .NET but it seems to me the purpose of setting the service to be dynamic is so that you can change the URL elsewhere, but when I do this it just gets ignored! Am I doing something wrong?

  • ODBC and NLS_LANG

    - by Michael S.
    Let's say that I've created two different program executables, e.g. in C++. For some reason, the two programs internals representation of text are different from each other. Let's say the first program is using text representation A and the other text representation B. It could be a specific 8-bit ANSI codepage, Unicode/UTF-8 or Unicode/UTF-16 or whatever. Now each program want to communicate text (add/retrieve data) to/from the same database table on a (database) server. Each program communicates with the database through ODBC. So the programs do not know what database system they they are communicating with. In this specific case through the database is actually a Oracle RDMS database and the database server administrator has setup the database to use UTF-8. On the system on which the programs are running an appropriate ODBC driver is available, so that the programs can connect through ODBC. Each program will treat and convert from the ODBC data type SQL_C_CHAR to its internal text representation appropriately. I assume that the programs cannot do no other than to assume a specific encoding returned for SQL_C_CHAR text. If not the programs has to be told which encoding that is. For Oracle, I know that the NLS_LANG environment variable can be used on the client. I assume it affects the ODBC driver (related to SQL_C_CHAR) to convert from a specific encoding (as given by NLS_LANG) to the internal encoding of the database (in this example UTF-8) and vice-versa. If the machine running my programs are having a NLS_LANG this setting will affect the byte sequences returned for SQL_C_CHAR so my programs cannot suddenly assume a specific encoding for the text returned via SQL_C_CHAR. Is it possible to setup the ODBC connection (preferably programmatically at runtime), so that it takes care of text conversions appropriately for the two programs, i.e. from/to representation to/from UTF-8 and from/to representation B to/from UTF-8? Regards, /Michael PS. As the programs are connecting through ODBC I don't think it would be nice that they should now anything about NLS_LANG as this is a Orcacle specific environment variable.

  • jQuery ajax delete script not actually deleting.

    - by werm
    I have a little personal webapp that I'm working on. I have a link that, when clicked, is supposed to make an ajax call to a php that is supposed to delete that info from a database. For some unknown reason, it won't actually delete the row from the database. I've tried everything I know, but still nothing. I'm sure it's something incredibly easy... Here are the scripts involved. Database output: $sql = "SELECT * FROM bookmark_app"; foreach ($dbh->query($sql) as $row) { echo '<div class="box" id="',$row['id'],'"><img src="images/avatar.jpg" width="75" height="75" border="0" class="avatar"/> <div class="text"><a href="',$row['url'],'">',$row['title'],'</a><br/> </div> /*** Click to delete ***/ <a href="?delete=',$row['id'],'" class="delete">x</a></div> <div class="clear"></div>'; } $dbh = null; Ajax script: $(document).ready(function() { $("a.delete").click(function(){ var element = $(this); var noteid = element.attr("id"); var info = 'id=' + noteid; $.ajax({ type: "GET", url: "includes/delete.php", data: info, success: function(){ element.parent().eq(0).fadeOut("slow"); } }); return false; }); }); Delete code: include('connect.php'); //delete.php?id=IdOfPost if($_GET['id']){ $id = $_GET['id']; //Delete the record of the post $delete = mysql_query("DELETE FROM `db` WHERE `id` = '$id'"); //Redirect the user header("Location:xxxx.php"); }

  • [iphone,twitter] Accessing the Twitter API through a proxy using NSURLConnectionsm, OAuth problem

    - by akaii
    I'm having no problems with sending an update directly via hxxps://api.twitter.com/, but the app (for the Iphone, I'm using NSURLConnections) I'm working is supposed to allow the user to select a preferred proxy (e.g. hxxps://twitter-proxy.appspot.com/api/ or hxxps://nest.onedd.net/api/), and I keep getting a 401 error (Failed to validate oauth signature and token) whenever I try to get an access token via these proxies. Even though I send my POST request to the proxy, I am still using the direct url for the api (https:// api.twitter.com/[rest api path]) in the base string. Despite the 401 error message above, the status code I'm actually getting from connection:didReceiveResponse: is 200, probably because it was able to successfully contact the proxy... Is there anything else that I need to consider when using a proxy to access the API? Should anything in the authorization header change, for example? Or the base string? I can manage to connect via Basic Auth without issue, but support for that will be dropped in a month. On a somewhat unrelated note... What are the possible causes of Twitter's error 403, and how do you distinguish between them? Is the only way to differentiate an error due to exceeding the status update limit for an hour (150 per hour) vs for a day (1000 per day) by checking the string reply returned in the response? Is there any way for me to simulate a status update limit error without going through the motions of actually sending 150/1000 tweets?

  • Strange behavior with complex Q object filter queries in Django

    - by HWM-Rocker
    Hi I am trying to write a tagging system for Django, but today I encountered a strange behavior in filter or the Q object (django.db.models.Q). I wrote a function, that converts a search string into a Q object. The next step would be to filter the TaggedObject with these query. But unfortunately I get a strange behavior. when I search (id=20) = Q: (AND: ('tags__tag__id', 20)) and it returns 2 Taged Objects with the ID 1127 and 132 when I search (id=4) = Q: (AND: ('tags__tag__id', 4)) and it returns also 2 Objects, but this time 1180 and 1127 until here is everything fine, but when i make a little bit more complex query like (id=4) or (id=20) = Q: (OR: ('tags__tag__id', 4), ('tags__tag__id', 20)) then it returns 4(!) Objects 1180, 1127, 1127, 132 But the object with the ID 1127 is returned twice, but thats not the behaviour I want. Do I have to live with it, and uniqify that list or can I do something different. The representation of the Q object looks fine for me. But the worst is now, when I search for (id=20) and (id=4) = Q: (AND: ('tags__tag__id', 20), ('tags__tag__id', 4)) then it returns no object at all. But why? The representation should be ok and the object with the id 1127 is tagged by both. What am I missing? Here are also the relevant parts of the classes, that are involved: class TaggedObject(models.Model): """ class that represent a tagged object """ tags = generic.GenericRelation('ObjectTagBridge', blank=True, null=True) class ObjectTagBridge(models.Model): """ Help to connect a generic object to a Tag.

  • Detect NetStream events with AS3 Video Object (not component)

  • Simplest way to debug an android bluetooth application

    - by intiha
    I am trying to test and build a sample android application that can simply connect to a BT server to send and receive a few packets. Since the emulator has no support what is the next best thing to test BT communication? Can I just run a code that acts as a server on my laptop and dumps BT connection onto a console? Do I have to write this code, or is their a simple tool that saves me that hassle? One more thing, I have windows 7, and currently I attach to my PC an anycom USB BT adapter. This is able to show up my nexus one as a BT device. I can pair to my laptop but connection always fails. When it tries to pair I have tried both 0000 and 1234 as suggested on my nexus, but in my connection list it still lists my laptop as paired but not connected. Any idea why? I searched for this problem and apparently people talk about rebooting and power cycling BT, but these solutions dont work for me. Thanks. Affan.

  • Establishing persistent connection to a database in Java

    - by gmile
    I've ran through several examples over the web, and found that every single time I need something from the DB, I should write the following code: try { // Step 1: Load the JDBC driver. Class.forName("mysql_driver_name"); // Step 2: Establish the connection to the database. String url = "jdbc:string_to_mysql_server"; Connection conn = DriverManager.getConnection(url,"user1","password"); // fetch from the DB ... } catch (Exception e) { System.err.println("Got an exception! "); System.err.println(e.getMessage()); } It's very annoying to put up this code every time I want something from the DB, so the question is - is there a way to only once connect entirely all my app to the DB somehow at the very start point, avoiding copy-pasting mentioned code, and then be able to do everything I want with DB? I've quickly looked through NetBeans's Project menu, but didn't find any clue on how to configurate a persistent connection to a selected DB. If it's important, i'm writing a purely desktop app, i.e. using Java EE. Also, it's worth mentioning that I'm a kinda beginner in Java.

  • .NET How would I build a DAL to meet my requirments?

    - by Jonno
    Assuming that I must deploy an asp.net app over the following 3 servers: 1) DB - not public 2) 'middle' - not public 3) Web server - public I am not allowed to connect from the web server to the DB directly. I must pass through 'middle' - this is purely to slow down an attacker if they breached the web server. All db access is via stored procedures. No table access. I simply want to provide the web server with a ado dataset (I know many will dislike this, but this is the requirement). Using asmx web services - it works, but XML serialisation is slow and it's an extra set of code to maintain and deploy. Using a ssh/vpn tunnel so that the one connects to the db 'via' the middle server, seems to remove any possible benefit of maintaining 'middle'. Using WCF binary/tcp removes the XML problem, but still there is extra code. Is there an approach that provides the ease of ssh/vpn, but the potential benefit of having the dal on the middle server? Many thanks.

  • How can I execute a .sql from C#?

    - by J. Pablo Fernández
    For some integration tests I want to connect to the database and run a .sql file that has the schema needed for the tests to actually run, including GO statements. How can I execute the .sql file? (or is this totally the wrong way to go?) I've found a post in the MSDN forum showing this code: using System.Data.SqlClient; using System.IO; using Microsoft.SqlServer.Management.Common; using Microsoft.SqlServer.Management.Smo; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { string sqlConnectionString = "Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True"; FileInfo file = new FileInfo("C:\\myscript.sql"); string script = file.OpenText().ReadToEnd(); SqlConnection conn = new SqlConnection(sqlConnectionString); Server server = new Server(new ServerConnection(conn)); server.ConnectionContext.ExecuteNonQuery(script); } } } but on the last line I'm getting this error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --- System.TypeInitializationException: The type initializer for '' threw an exception. --- .ModuleLoadException: The C++ module failed to load during appdomain initialization. --- System.DllNotFoundException: Unable to load DLL 'MSVCR80.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E). I was told to go and download that DLL from somewhere, but that sounds very hacky. Is there a cleaner way to? Is there another way to do it? What am I doing wrong? I'm doing this with Visual Studio 2008, SQL Server 2008, .Net 3.5SP1 and C# 3.0.

  • PHP: tips/resources/patterns for learning to implement a basic ORM

    - by BoltClock
    I've seen various MVC frameworks as well as standalone ORM frameworks for PHP, as well as other ORM questions here; however, most of the questions ask for existing frameworks to get started with, which is not what I'm looking for. (I have also read this SO question but I'm not sure what to make of it, and the answers are vague.) Instead, I figured I'd learn best by getting my hands dirty and actually writing my own ORM, even a simple one. Except I don't really know how to get started, especially since the code I see in other ORMs is so complicated. With my PHP 5.2.x (this is important) MVC framework I have a basic custom database abstraction layer, that has: Very simple methods like connect($host, $user, $pass, $base), query($sql, $binds), etc Subclasses for each DBMS that it supports A class (and respective subclasses) to represent SQL result sets But does not have: Active Record functionality, which I assume is an ORM thing (correct me if I'm wrong) I've read up a little about ORM, and from my understanding they provide a means to further abstract data models from the database itself by representing data as nothing more than PHP-based classes/objects; again, correct me if I am wrong or have missed out in any way. Still, I'd like some simple tips from anyone else who's dabbled more or less with ORM frameworks. Is there anything else I need to take note of, simple example code for me to refer to, or resources I can read? Thanks a lot in advance!

  • Easy bidirectional communication via P2P NetStream

    - by andsve
    I've been looking into the P2P support in Flash 10, using Adobe Stratus service. I have successfully been able to send data from one user to another, put my problem is that I haven't figured out how to send data back in some easy way (or as some kind of response to the first call). What I'm currently doing; First set up a connection with Stratus service nc = new NetConnection(); nc.addEventListener(NetStatusEvent.NET_STATUS, ncStatusHandler); nc.connect(APPLICATION_URL + DEVELOPER_KEY); On the "server" side I do: sendStream = new NetStream(nc, NetStream.DIRECT_CONNECTIONS); sendStream.addEventListener(NetStatusEvent.NET_STATUS, sendStreamHandler); sendStream.publish("file"); And on the "client" side: // remoteFileID.text is manually copied by the user from the server (which is nc.nearID). recvStream = new NetStream(nc, remoteFileID.text); recvStream.client = this; recvStream.addEventListener(NetStatusEvent.NET_STATUS, recvStreamHandler); recvStream.play("file"); Then I call a remote function on the client: ... sendStream.send("aRemoteFunction", parameterData); ... Now my problem; I want to do the same from the client to the server, to notify that everything went well, or something failed. From what I understand, I will have to setup a new NetStream from the client to the server (i.e publish on the client and play on the server). But to accomplish this, the server need to know the nc.nearID on the client. Is it possible to get that ID without forcing the user to manually copy it from the client to server? Or, is there an easier way for the client to talk back to the server that I am missing?
