  • Encoding issue: Cocoa Error 261?

    - by Attacus
    So I'm fetching a JSON string from a php script in my iPhone app using: NSURL *baseURL = [NSURL URLWithString:@"test.php"]; NSError *encodeError = [[NSError alloc] init]; NSString *jsonString = [NSString stringWithContentsOfURL:baseURL encoding:NSUTF8StringEncoding error:&encodeError]; NSLog(@"Error: %@", [encodeError localizedDescription]); NSLog(@"STRING: %@", jsonString); The JSON string validates when I test the output. Now I'm having an encoding issue. When I fetch a single echo'd line such as: { "testKey":"é" } (I'm aware I could\should be using NSUrlConnection for asynchronous fetching of data, but at this point in the app development, I don't really need it.) The JSON parser works fine and I am able to create a valid JSON object. However, when I fetch my 2MB JSON string, I get presented with: Error: Operation could not be completed. (Cocoa error 261.) and a Null string. My PHP file is UTF8 itself and I am not using utf8_encode() because that seems to double encode the data since I'm already pulling the data as NSUTF8StringEncoding. Either way, in my single-echo test, it's the approach that allowed me to successfully log \ASDAS style UTF8 escapes when building the JSON object. What could be causing the error in the case of the larger string? Also, I'm not sure if it makes a difference, but I'm using the php function addslashes() on my parsed php data to account for quotes and such when building the JSON string.

  • Text mining with PHP

    - by garyc40
    Hi, I'm doing a project for a college class I'm taking. I'm using PHP to build a simple web app that classify tweets as "positive" (or happy) and "negative" (or sad) based on a set of dictionaries. The algorithm I'm thinking of right now is Naive Bayes classifier or decision tree. However, I can't find any PHP library that helps me do some serious language processing. Python has NLTK (http://www.nltk.org). Is there anything like that for PHP? I'm planning to use WEKA as the back end of the web app (by calling Weka in command line from within PHP), but it doesn't seem that efficient. Do you have any idea what I should use for this project? Or should I just switch to Python? Thanks

  • threaded serial port IOException when writing

    - by John McDonald
    Hi, I'm trying to write a small application that simply reads data from a socket, extracts some information (two integers) from the data and sends the extracted information off on a serial port. The idea is that it should start and just keep going. In short, it works, but not for long. After a consistently short period I start to receive IOExceptions and socket receive buffer is swamped. The thread framework has been taken from the MSDN serial port example. The delay in send(), readThread.Join(), is an effort to delay read() in order to allow serial port interrupt processing a chance to occur, but I think I've misinterpreted the join function. I either need to sync the processes more effectively or throw some data away as it comes in off the socket, which would be fine. The integer data is controlling a pan tilt unit and I'm sure four times a second would be acceptable, but not sure on how to best acheive either, any ideas would be greatly appreciated, cheers. using System; using System.Collections.Generic; using System.Text; using System.IO.Ports; using System.Threading; using System.Net; using System.Net.Sockets; using System.IO; namespace ConsoleApplication1 { class Program { static bool _continue; static SerialPort _serialPort; static Thread readThread; static Thread sendThread; static String sendString; static Socket s; static int byteCount; static Byte[] bytesReceived; // synchronise send and receive threads static bool dataReceived; const int FIONREAD = 0x4004667F; static void Main(string[] args) { dataReceived = false; readThread = new Thread(Read); sendThread = new Thread(Send); bytesReceived = new Byte[16384]; // Create a new SerialPort object with default settings. _serialPort = new SerialPort("COM4", 38400, Parity.None, 8, StopBits.One); // Set the read/write timeouts _serialPort.WriteTimeout = 500; _serialPort.Open(); string moveMode = "CV "; _serialPort.WriteLine(moveMode); s = null; IPHostEntry hostEntry = Dns.GetHostEntry("localhost"); foreach (IPAddress address in hostEntry.AddressList) { IPEndPoint ipe = new IPEndPoint(address, 10001); Socket tempSocket = new Socket(ipe.AddressFamily, SocketType.Stream, ProtocolType.Tcp); tempSocket.Connect(ipe); if (tempSocket.Connected) { s = tempSocket; s.ReceiveBufferSize = 16384; break; } else { continue; } } readThread.Start(); sendThread.Start(); while (_continue) { Thread.Sleep(10); ;// Console.WriteLine("main..."); } readThread.Join(); _serialPort.Close(); s.Close(); } public static void Read() { while (_continue) { try { //Console.WriteLine("Read"); if (!dataReceived) { byte[] outValue = BitConverter.GetBytes(0); // Check how many bytes have been received. s.IOControl(FIONREAD, null, outValue); uint bytesAvailable = BitConverter.ToUInt32(outValue, 0); if (bytesAvailable > 0) { Console.WriteLine("Read thread..." + bytesAvailable); byteCount = s.Receive(bytesReceived); string str = Encoding.ASCII.GetString(bytesReceived); //str = Encoding::UTF8->GetString( bytesReceived ); string[] split = str.Split(new Char[] { '\t', '\r', '\n' }); string filteredX = (split.GetValue(7)).ToString(); string filteredY = (split.GetValue(8)).ToString(); string[] AzSplit = filteredX.Split(new Char[] { '.' }); filteredX = (AzSplit.GetValue(0)).ToString(); string[] ElSplit = filteredY.Split(new Char[] { '.' }); filteredY = (ElSplit.GetValue(0)).ToString(); // scale values int x = (int)(Convert.ToInt32(filteredX) * 1.9); string scaledAz = x.ToString(); int y = (int)(Convert.ToInt32(filteredY) * 1.9); string scaledEl = y.ToString(); String moveAz = "PS" + scaledAz + " "; String moveEl = "TS" + scaledEl + " "; sendString = moveAz + moveEl; dataReceived = true; } } } catch (TimeoutException) {Console.WriteLine("timeout exception");} catch (NullReferenceException) {Console.WriteLine("Read NULL reference exception");} } } public static void Send() { while (_continue) { try { if (dataReceived) { // sleep Read() thread to allow serial port interrupt processing readThread.Join(100); // send command to PTU dataReceived = false; Console.WriteLine(sendString); _serialPort.WriteLine(sendString); } } catch (TimeoutException) { Console.WriteLine("Timeout exception"); } catch (IOException) { Console.WriteLine("IOException exception"); } catch (NullReferenceException) { Console.WriteLine("Send NULL reference exception"); } } } } }

  • How to overcome vc++ warning C4003 while writing common code for both gcc and vc++

    - by compbugs
    I have a code that is compiled in both gcc and vc++. The code has a common macro which is called in two scenarios. When we pass some parameters to it. When we don't want to pass any parameters to it. An example of such a code is: #define B(X) A1##X int main() { int B(123), B(); return 0; } The expect output from the pre-processing step of compilation is: int main() { int A1123, A1; return 0; } The output for both gcc and vc++ is as expected, but vc++ gives a warning: warning C4003: not enough actual parameters for macro 'B' How can I remove this warning and yet get the expected output? Thanks.

  • Grails Mail port configuration

    - by bsreekanth
    Hello, I am trying to send mail through grails mail plugin. I configured according to the documentation, and also followed few blog posts (http://blog.lourish.com/2010/04/02/sending-asynchronous-html-email-in-grails-with-activemq-jms-and-gmail/). That post mention that the closure way of declaring the configuration overrides others, but not true. Anyway I tried both approach, but seems like the port is still use the smtp default one. I get the below exception. exception: org.springframework.mail.MailSendException: Mail server connection failed; nested exception is javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25; nested exception is: java.net.ConnectException: Connection refused: connect Now, I wrote a small program directly using the java mail library, and I could send the mail with that. The configuration is shown below. tried additional config "mail.smtp.port":"465"", but no change.. used the parameters mentioned in the above blog post, result same grails { mail { host = "smtp.gmail.com" port = "465" username = "[email protected]" password = "mypwd" props = ["mail.smtp.auth":"true", // "mail.smtp.port":"465", "mail.smtp.socketFactory.port":"465", "mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory", "mail.smtp.socketFactory.fallback":"false"] } } thanks in advance.. Update: It is not port or firewall config, as when I made a grails application from scratch, and tried with the same config, everything works. Also, asked in grails forum http://grails.1312388.n4.nabble.com/grails-mail-mailSender-does-not-have-config-values-td2237704.html#a2237704 . Hope get a lead to try.

  • JQuery Validation Plugin: Use Custom Ajax Method

    - by namtax
    Hi Looking for some assistance with the Jquery form validation plugin if possible. I am validating the email field of my form on blur by making an ajax call to my database, which checks if the text in the email field is currently in the database. // Check email validity on Blur $('#sEmail').blur(function(){ // Grab Email From Form var itemValue = $('#sEmail').val(); // Serialise data for ajax processing var emailData = { sEmail: itemValue } // Do Ajax Call $.getJSON('http://localhost:8501/ems/trunk/www/cfcs/admin_user_service.cfc?method=getAdminUserEmail&returnFormat=json&queryformat=column', emailData, function(data){ if (data != false) { var errorMessage = 'This email address has already been registered'; } else { var errorMessage = 'Good' } }) }); What I would like to do, is encorporate this call into the rules of my JQuery Validation Plugin...e.g $("#setAdminUser").validate({ rules:{ sEmail: { required: function(){ // Replicate my on blur ajax email call here } }, messages:{ sEmail: { required: "this email already exists" } }); Wondering if there is anyway of achieving this? Many thanks

  • Try/Catch with jquery ajax request

    - by Anthony
    I am trying to build a Google Chrome extension that makes an ajax request. Something similar to the GMail Checker extension. The problem is that when I do the request using jquery, and I put in the wrong username/password, it fails silently, with the error callback function ignored. If I move the ajax call out of the background.html script (where I can't see the requests in the developer window), to the options.html script, I get a dialog box to re-authenticate. If I hit cancel, THEN the jquery error callback fires. But in the original model extension (again, the Gmail checker), they use plain (non-jquery) ajax calls with a try/catch, and if I put in the wrong credentials, I get an alert saying as much. I tried wrapping the entire jquery call in a try/catch, like so: try { $.ajax({ type: "POST", url: someurl, contentType : "text/xml", data: somedata, username: user, password: pass, success: function(data,status,xhr){ alert("Hurrah!"); }, error: function(xhr, status, error){ alert("Error!" + xhr.status); }, dataType: "xml" }); } catch(e) { alert("You messed something up!"); } But still nothing. Is the error due to it being asynchronous, or is Chrome not returning the request as an error since it wants to re-prompt for credentials? Or do I just not know how to use try/catch? Update Here is a very slimmed down version of how the model code does the request: var req = new XMLHttpRequest(); req.onreadystatechange = function() { try { if ( req.readyState == 4 ) { //Do some stuff with results } } catch (ex) { alert('Error parsing response.'); } } try { req.send (data); } catch (ex) { alert ('Something went wrong with the request.'); }

  • Program and debugger quit without indication of problem

    - by spender
    OK, not quite a Heisenbug but similar in nature. I'm developing a WPF application. When debugging, the logic reaches a certain point, then the application quits for no reason. VS debugger catches nothing and the only indication of a problem is the following in the output window: The program '[6228] SomeApp.vshost.exe: Managed (v4.0.30319)' has exited with code 1073741855 (0x4000001f). When debugging the release version, or indeed running the debug build out of the debugger (in fact all combos that aren't running the debug version in debugger), everything works fine. I'm trying to catch unhandled exceptions with the following code: AppDomain .CurrentDomain .UnhandledException += (sender, e) => { Debug.WriteLine("Unhandled Exception " + e.ExceptionObject); }; Application .Current .DispatcherUnhandledException += (sender1, e1) => { Debug.WriteLine("DispatcherUnhandledException " + e1.Exception); }; ...but I'm not catching anything. I'm considering peppering the app with debug output statements, but it's highly asynchronous so reading this will be both arduous and tedious. So tell me, if you can... how do I start figuring WTF is going on?

  • Looking for a communication framework for delphi

    - by Ryan
    I am looking for a communication framework for delphi, we know there are so many communication frameworks for other languages , wcf, ecf and so forth, but i have nerver found the one for delphi till now , anybody who knows about it can give me an ider? There are some requirements i need ,as follows: Building an application(server or client) without caring how to do communications with each other between two endpoints. Imagine that we use mailbox for exchanging messages,it seems that the communication is transparent. Supports communication protocol extending. We often need to exchange the messages between 2 devices, but the communication protocol is not a public or general one, so we need to extend the framework,to implement a communication protocol for receiving or sending a message completely. Supports asynchronous and synchronous communication Supports transmission protocol extending. The transmission protocol can implemented by winsocket, pipes, com, windows message, mailslot and so forth. In client application, we can write code snips like follows: var server: TDelphiCommunicationServer; session : ICommunicationSession; request, response: IMessage; begin session := server.CreateSession('IP', Port); request := TLoginRequest.Create; session.SynSendMessage(request); session.WaitForMessage(response, INFINITE); ....... end; In above code snips , TLoginRequest has implemented the message interface.

  • RequestDispatcher forward between Tomcat instances

I am looking at options to distribute this load and I would like to know if it is possible using Tomcat or another platform to forward requests between Servlets sitting on different servers using a cluster type configuration or similar.

  • Workflow Foundation 4 WorkflowServiceHost Message Correlation

    - by Lygpt
    I have 2 methods on a workflow service hosted in WorkflowServiceHost. The first method is called and starts the regular workflow sequence - talking to other web services, database work etc but on some occassions will pause and persist to db (as-in the delay activity) and wait for some human action to take place before continuing. I need my second method to be able to hook into this persisted workflow, change a local variable and then continuing processing. I have looked at message based correlation in workflow but can only seem to find examples where some kind of infinite while loop keeps the workflow instance active so that the second service method call can arrive whilst it's still running. Because my workflow instance will be delayed/persisted, the second service call doesn't seem to get anywhere (I can't have an infinite while loop keeping the workflow instance active). I hope this makes sense - cheers!

  • iPhone: Memory leak when using NSOperationQueue...

    - by MacTouch
    Hi, I'm sitting here for at least half an hour to find a memory leak in my code. I just replaced an synchronous call to a (touch) method with an asynchronous one using NSOperationQueue. The Leak Inspector reports a memory leak after I did the change to the code. What's wrong with the version using NSOperationQueue? Version without a MemoryLeak -(NSData *)dataForKey:(NSString*)ressourceId_ { NSString *path = [self cachePathForKey:ressourceId_]; // returns an autoreleased NSString* NSString *cacheKey = [self cacheKeyForRessource:ressourceId_]; // returns an autoreleased NSString* NSData *data = [[self memoryCache] valueForKey:cacheKey]; if (!data) { data = [self loadData:path]; // returns an autoreleased NSData* if (data) { [[self memoryCache] setObject:data forKey:cacheKey]; } } [[self touch:path]; return data; } Version with a MemoryLeak (I do not see any) -(NSData *)dataForKey:(NSString*)ressourceId_ { NSString *path = [self cachePathForKey:ressourceId_]; // returns an autoreleased NSString* NSString *cacheKey = [self cacheKeyForRessource:ressourceId_]; // returns an autoreleased NSString* NSData *data = [[self memoryCache] valueForKey:cacheKey]; if (!data) { data = [self loadData:path]; // returns an autoreleased NSData* if (data) { [[self memoryCache] setObject:data forKey:cacheKey]; } } NSInvocationOperation *touchOp = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(touch:) object:path]; [[self operationQueue] addOperation:touchOp]; [touchOp release]; return data; } And of course, the touch method does nothing special too. Just change the date of the file. -(void)touch:(id)path_ { NSString *path = (NSString *)path_ NSFileManager *fm = [NSFileManager defaultManager]; if ([fm fileExistsAtPath:path]) { NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:[NSDate date], NSFileModificationDate, nil]; [fm setAttributes: attributes ofItemAtPath:path error:nil]; } }

  • Delphi SAPI Text-To-Speech

    - by Andreas Rejbrand
    First of all: this is not a duplicate of http://stackoverflow.com/questions/1021490/delphi-and-sapi. I have a specific problem with the "SAPI in Delphi" subject. I have used the excellent Import Type-Library guide in Delphi 2009 to get a TSpVoice component in the component palette. This works great. With var SpVoice: TSpVoice; I can write SpVoice.Speak('This is an example.', 1); to get asynchronous audio output. First question According to the documentation, I would be able to write SpVoice.Speak('This is an example.', 0); to get synchronous audio output, but instead I get an EZeroDivide exception. Why's that? Second question But more importantly, I would like to be able to create the SpVoice object dynamically (I think this is called to "late-bound" the SpVoice object), partly because only a very small fraction of all sessions of my app will use it, and partly because I do not want to assume the existance of the SAPI server on the end-user's system. To this end, I tried procedure TForm1.FormClick(Sender: TObject); var SpVoice: Variant; begin SpVoice := CreateOleObject('SAPI.SpVoice'); SpVoice.Speak('this is a test', 0); end; which apparently does nothing at all! (Replacing the 0 with 1 gives me the EZeroDivide exception.) Disclaimer I am rather new to COM/OLE automation. I am sorry for any ignorance or stupidity shown by me in this post...

  • Extracting ""((Adj|Noun)+|((Adj|Noun)(Noun-Prep)?)(Adj|Noun))Noun"" from Text (Justeson & Katz, 1995)

    - by ssuhan
    I would like to query if it is possible to extract ((Adj|Noun)+|((Adj|Noun)(Noun-Prep)?)(Adj|Noun))Noun proposed by Justeson and Katz (1995) in R package openNLP? That is, I would like to use this linguistic filtering to extract candidate noun phrases. I cannot well understand its meaning. Could you do me a favor to explain it or transform such representation into R language. Many thanks. Maybe we can start the sample code from: library("openNLP") acq <- "This paper describes a novel optical thread plug gauge (OTPG) for internal thread inspection using machine vision. The OTPG is composed of a rigid industrial endoscope, a charge-coupled device camera, and a two degree-of-freedom motion control unit. A sequence of partial wall images of an internal thread are retrieved and reconstructed into a 2D unwrapped image. Then, a digital image processing and classification procedure is used to normalize, segment, and determine the quality of the internal thread." acqTag <- tagPOS(acq) acqTagSplit = strsplit(acqTag," ")

The problem already was solved in a very bad way, but I need to fix it quickly. Anyone knows some tricks to debug better it without open the frameworks code? Cheers, Felipe

  • Creating an independent draw thread using pthreads (C++)

    - by sagekilla
    Hi all, I'm working on a graphical application which looks something like this: while (Simulator.simulating) { Simulator.update(); InputManager.processInput(); VideoManager.draw(); } I do this several times a second, and in the vast majority of cases my computation will be taking up 90 - 99% of my processing time. What I would like to do is take out the processInput and draw functions and have each one run independently. That way, I can have the input thread always checking for input (at a reasonable rate), and the draw thread attempting to redraw at a given frame rate. My issue is I'm not sure how I can properly do this. How would I properly initialize my pthread_t and associated pthread_attr_t so that the thread runs without blocking what I'm doing? Any help or even a link is appreciated, thanks!

  • Comet and Simultaneous Ajax request

    - by Amitd
    Hi , I am trying to use a COMET solution using ASP.NET . Trouble is i want to implement sending and notification part in the same page. On IE7, whenever i try to send a request ,it just gets queued up. After reading on internet and stackoverflow pages i found that i can only do 2 simultaneous asyn ajax requests per page. So until i close my comet Ajax request,my 2nd request doesnt get completed ,doesnt even go out from the browser. And when i checked with Firefox i just one Ajax comet request running all time..so doesnt that leave me one more ajax request? Also the solution uses IRequiressessionstate for Asynchronous HTTP Handler which i had removed.but still it creates problems on multiple instances of IE7. I had one work around which is stated here http://support.microsoft.com/kb/282402 it means we can increase the request limit from registry by default is 2. By changing "MaxConnectionsPer1_0Server" key in hive "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings" we can increase the number of requests. Basically i want to broadcast information to multiple clients connected to a server using Comet and the clients can also send messages to the Server. Broadcasting works but the send request back to server doesnt work. Im using IIS 6 and ASP.NET . Are there any more workarounds or ways to send more requests?

  • Readdirectorychanges not working with big file

    - by sanky
    i was working with readdirectorychangesW till i encountered an unwanted behavior.below is short reference the way i am using my readdirectorychanges func. The behavior is that in case a big file in GBs is copied to the watched directory i get the notification immediately and thereby i start doing my operation according to the notification i receive ,but the file IO ( copy operation is still pending) and that results in unxpected state. Can anyone please suggest a way to synchronize this operation. I want the copy operation(that gave me notification) to get completed first then i want to do my processing. while(ReadDirectoryChangesW( hDir, pBuffer, nBufSize, FALSE, FILE_NOTIFY_CHANGE_FILE_NAME, &BytesReturned, NULL, NULL )) { pBufferCurrent = pBuffer; while(pBufferCurrent) { switch(pBufferCurrent->Action) { case FILE_ACTION_ADDED: break; default: break; } if (pBufferCurrent->NextEntryOffset) pBufferCurrent = (FILE_NOTIFY_INFORMATION*)(((oef_u8_t*)pBufferCurrent) + pBufferCurrent->NextEntryOffset); else pBufferCurrent = NULL; }

  • Ignoring 'A' and 'The' when sorting with XSLT

    - by ChrisV
    I would like to have a list sorted ignoring any initial definite/indefinite articles 'the' and 'a'. For instance: The Comedy of Errors Hamlet A Midsummer Night's Dream Twelfth Night The Winter's Tale I think perhaps in XSLT 2.0 this could be achieved along the lines of: <xsl:template match="/"> <xsl:for-each select="play"/> <xsl:sort select="if (starts-with(title, 'A ')) then substring(title, 2) else if (starts-with(title, 'The ')) then substring(title, 4) else title"/> <p><xsl:value-of select="title"/></p> </xsl:for-each> </xsl:template> However, I want to use in-browser processing, so have to use XSLT 1.0. Is there any way to achieve this in XLST 1.0?

  • C# - Can FileHelper FieldConverter routines refer to other fields in the record?

    - by Pete
    I am using the excellent FileHelpers library to process a fixed-length airline schedule file. I have a date field, then a few fields later on in the record, a time field. I want to combine both of these in the FileHelpers record class, and know there is a custom FieldConverter attribute. With this attribute, you provide a custom function to handle your field data and implement StringToField and FieldToString. My question is: can I pass other fields (already read) to this customer FieldConverter too, so I can combine Date and Time together. FieldConverter has an implementation that allows you to refer to both a custom processing class AND 'other strings' or even an array of object. But, given this is done in the attribute definition, I am struggling to access this earlier-field reference. [FieldFixedLength(4)] [FieldConverter(typeof(MyTimeConverter),"eg. ScheduledDepartureDate")] public DateTime scheduledDepartureTime;
