  • CURL - https - solaris

    - by Vincent
    All, I am receiving the following error when I use PHP to curl to a https site. Both PHP and the https site are hosted on Solaris. This error seems to occur occassionally but frequently. error:80089077:lib(128):func(137):reason(119) This is the curl code I am using: $ch = curl_init(); $devnull = fopen('/tmp/cookie.txt', 'w'); curl_setopt($ch, CURLOPT_STDERR, $devnull); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_URL, $desturl); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0); curl_setopt($ch, CURLOPT_CONNECTTIMEOUT,800); curl_setopt($ch, CURLOPT_AUTOREFERER, true); curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate'); curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata); $retVal = curl_exec($ch); print_r(curl_error($ch)); curl_close($ch); if ($devnull) { fclose($devnull); } How can I fix this error? If not, is there an alternative to curl?

  • Getting error: "This webpage is not available" for my chrome app's options page

    - by Don Rhummy
    My CRX had the proper html page options.html in it, the manifest declares it properly (it shows up as a link on the chrome://extensions page) but when I click that link, Chrome gives the error: This webpage is not available The webpage at chrome-extension://invalid/ might be temporarily down or it may have moved permanently to a new web address. It says "invalid" but the app runs perfectly well (all the content scripts run, the background created a database and saved to it). Why would it show as invalid? Why doesn't it have the extensions' id? Here's the manifest: { "manifest_version": 2, "name": "MyAPP", "description": "My App", "version": "0.0.0.32", "minimum_chrome_version": "27", "offline_enabled": true, "options_page": "options.html", "icons": { "16": "images/icon16.png", "48": "images/icon48.png", "128": "images/icon128.png" }, "app": { "background": { "scripts": [ "scripts/background.js" ] } }, "permissions": [ "unlimitedStorage", "fullscreen", { "fileSystem": [ "write" ] }, "background", "<all_urls>", "tabs" ] } Does it need to be declared in "web_accessible_resources"? Any idea what's wrong? Update Adding to "web_accessible_resources" does not fix the issue. I added everything on that page too. update 2 It looks like it might be a Chrome bug for packaged apps. When I remove the "app" section in the manifest, it works! This is a bug since the Chrome app documentation states that apps can have options pages: https://developer.chrome.com/apps/options.html

  • AES Encryption Java Invalid Key length

    - by wuntee
    I am trying to create an AES encryption method, but for some reason I keep getting a 'java.security.InvalidKeyException: Key length not 128/192/256 bits'. Here is the code: public static SecretKey getSecretKey(char[] password, byte[] salt) throws NoSuchAlgorithmException, InvalidKeySpecException{ SecretKeyFactory factory = SecretKeyFactory.getInstance("PBEWithMD5AndDES"); // NOTE: last argument is the key length, and it is 256 KeySpec spec = new PBEKeySpec(password, salt, 1024, 256); SecretKey tmp = factory.generateSecret(spec); SecretKey secret = new SecretKeySpec(tmp.getEncoded(), "AES"); return(secret); } public static byte[] encrypt(char[] password, byte[] salt, String text) throws NoSuchAlgorithmException, InvalidKeySpecException, NoSuchPaddingException, InvalidKeyException, InvalidParameterSpecException, IllegalBlockSizeException, BadPaddingException, UnsupportedEncodingException{ SecretKey secret = getSecretKey(password, salt); Cipher cipher = Cipher.getInstance("AES"); // NOTE: This is where the Exception is being thrown cipher.init(Cipher.ENCRYPT_MODE, secret); byte[] ciphertext = cipher.doFinal(text.getBytes("UTF-8")); return(ciphertext); } Can anyone see what I am doing wrong? I am thinking it may have something to do with the SecretKeyFactory algorithm, but that is the only one I can find that is supported on the end system I am developing against. Any help would be appreciated. Thanks.

  • Using JBoss EL on Weblogic 11g (10.3.1.0)

    - by golfradio
    Hi, I have a facelets 1.2 application that I am running on Weblogic 11g. I want to use the JBoss EL implementation that allows me to call bean methods with arguments. For this, I have packaged the jboss-el-2.0.1.GA.jar in my WAR's WEB-INF/lib directory. I have also added a context-param in my web.xml to override the Sun implementation. <context-param> <param-name>com.sun.faces.expressionFactory</param-name> <param-value>org.jboss.el.ExpressionFactoryImpl</param-value> </context-param> But when I load a page that contains an expression like <ice:outputText value="#{errBean.getErrMsg(error.code)}"/> I get an expression parsing exception java.lang.Exception: javax.faces.FacesException: com.sun.el.parser.ParseException: Encountered "(" at line 1, column 25. Was expecting one of: "}" ... "." ... ... at com.sun.el.parser.ELParser.generateParseException(ELParser.java:1651) at com.sun.el.parser.ELParser.jj_consume_token(ELParser.java:1531) at com.sun.el.parser.ELParser.DeferredExpression(ELParser.java:134) at com.sun.el.parser.ELParser.CompositeExpression(ELParser.java:61) at com.sun.el.lang.ExpressionBuilder.createNodeInternal(ExpressionBuilder.java:128) at com.sun.el.lang.ExpressionBuilder.build(ExpressionBuilder.java:177) at com.sun.el.lang.ExpressionBuilder.createValueExpression(ExpressionBuilder.java:221) at com.sun.el.ExpressionFactoryImpl.createValueExpression(ExpressionFactoryImpl.java:81) at com.sun.facelets.tag.TagAttribute.getValueExpression(TagAttribute.java:256) Weblogic does not seem to be using the JBoss EL ExpressionFactoryImpl. I don't understand what is going on. This worked on Weblogic 9.2.2. What is it that I am doing wrong? Any help is appreciated. Thanks in advance.

  • Correct escaping of delimited identifers in SQL Server without using QUOTENAME

    - by Ross Bradbury
    Is there anything else that the code must do to sanitize identifiers (table, view, column) other than to wrap them in double quotation marks and "double up" and double quotation marks present in the identifier name? References would be appreciated. I have inherited a code base that has a custom object-relational mapping (ORM) system. SQL cannot be written in the application but the ORM must still eventually generate the SQL to send to the SQL Server. All identifiers are quoted with double quotation marks. string QuoteName(string identifier) { return "\" + identifier.Replace("\"", "\"\"") + "\""; } If I were building this dynamic SQL in SQL, I would use the built-in SQL Server QUOTENAME function: declare @identifier nvarchar(128); set @identifier = N'Client"; DROP TABLE [dbo].Client; --'; declare @delimitedIdentifier nvarchar(258); set @delimitedIdentifier = QUOTENAME(@identifier, '"'); print @delimitedIdentifier; -- "Client""; DROP TABLE [dbo].Client; --" I have not found any definitive documentation about how to escape quoted identifiers in SQL Server. I have found Delimited Identifiers (Database Engine) and I also saw this stackoverflow question about sanitizing. If it were to have to call the QUOTENAME function just to quote the identifiers that is a lot of traffic to SQL Server that should not be needed. The ORM seems to be pretty well thought out with regards to SQL Injection. It is in C# and predates the nHibernate port and Entity Framework etc. All user input is sent using ADO.NET SqlParameter objects, it is just the identifier names that I am concerned about in this question. This needs to work on SQL Server 2005 and 2008.

  • Secure Password Storage and Transfer

    - by Andras Zoltan
    I'm developing a new user store for my organisation and am now tackling password storage. The concepts of salting, HMAC etc are all fine with me - and want to store the users' passwords either salted and hashed, HMAC hashed, or HMAC salted and hashed - not sure what the best way will be - but in theory it won't matter as it will be able to change over time if required. I want to have an XML & JSON service that can act as a Security Token Service for client-side apps. I've already developed one for another system, which requires that the client double-encrypts a clear-text password using SHA1 first and then HMACSHA1 using a 128 unique key (or nonce) supplied by the server for that session only. I'd like to repeat this technique for the new system - upgrading the algo to SHA256 (chosen since implementations are readily available for all aforementioned platforms - and it's much stronger than SHA1) - but there is a problem. If I'm storing the password as a salted hash in the user-store, the client will need to be sent that salt in order to construct the correct hash before being HMACd with the unique session key. This would completely go against the point of using a salt in the first place. Equally, if I don't use salt for password storage, but instead use HMAC, it's still the same problem. At the moment, the only solution I can see is to use naked SHA256 hashing for the password in the user store, so that I can then use this as a starting point on both the server and the client for a more secure salted/hmacd password transfer for the web service. This still leaves the user store vulnerable to a dictionary attack were it ever to be accessed; and however unlikely that might be - assuming it will never happen simply doesn't sit well with me. Greatly appreciate any input.

  • EPIPE blocks server

    - by timn
    I have written a single-threaded asynchronous server in C running on Linux: The socket is non-blocking and as for polling, I am using epoll. Benchmarks show that the server performs fine and according to Valgrind, there are no memory leaks or other problems. The only problem is that when a write() command is interrupted (because the client closed the connection), the server will encounter a SIGPIPE. I am doing the interrupted artifically by running the benchmarking utility "siege" with the parameter -b. It does lots of requests in a row which all work perfectly. Now I press CTRL-C and restart the "siege". Sometimes I am lucky and the server does not manage to send the full response because the client's fd is invalid. As expected errno is set to EPIPE. I handle this situation, execute close() on the fd and then free the memory related to the connection. Now the problem is that the server blocks and does not answer properly anymore. Here is the strace output: accept(3, {sa_family=AF_INET, sin_port=htons(50611), sin_addr=inet_addr("127.0.0.1")}, [16]) = 5 fcntl64(5, F_GETFD) = 0 fcntl64(5, F_SETFL, O_RDONLY|O_NONBLOCK) = 0 epoll_ctl(4, EPOLL_CTL_ADD, 5, {EPOLLIN|EPOLLERR|EPOLLHUP|EPOLLET, {u32=158310248, u64=158310248}}) = 0 epoll_wait(4, {{EPOLLIN, {u32=158310248, u64=158310248}}}, 128, -1) = 1 read(5, "GET /user/register HTTP/1.1\r\nHos"..., 4096) = 161 write(5, "HTTP/1.1 200 OK\r\nContent-Type: t"..., 106) = 106 <<<<< write(5, "00001000\r\n", 10) = -1 EPIPE (Broken pipe) <<<<< Why did the previous write() work fine but not this one? --- SIGPIPE (Broken pipe) @ 0 (0) --- As you can see, the client establishes a new connection which consequently is accepted. Then, it's added to the EPOLL queue. epoll_wait() signalises that the client sent data (EPOLLIN). The request is parsed and and a response is composed. Sending the headers works fine but when it comes to the body, write() results in an EPIPE. It is not a bug in "siege" because it blocks any incoming connections, no matter from which client.

  • improving data extraction from text file in Java

    - by owca
    I have CSV file with sample data in this form : 220 30 255 0 0 Javascript 200 20 0 255 128 Thinking in java , where the first column is height, second thickness, next three are rgb values for color and last one is title. All need to be treated as separate variables. I have already written my own solution for this, but I'm wondering if there are no better/easier/shorter ways of doing this. Extracted data will then be used to create Book object, throw every Book into array of books and print it with swing. Here's the code : private static Book[] addBook(Book b, Book[] bookTab){ Book[] tmp = bookTab; bookTab = new Book[tmp.length+1]; for(int i = 0; i < tmp.length; i++){ bookTab[i] = tmp[i]; } bookTab[tmp.length] = b; return bookTab; } public static void main(String[] args) { Book[] books = new Book[0]; try { BufferedReader file = new BufferedReader(new FileReader("K:\\books.txt")); String s; while ((s = file.readLine()) != null) { int hei, thick, R, G, B; String tit; hei = Integer.parseInt(s.substring(0, 3).replaceAll(" ", "")); thick = Integer.parseInt(s.substring(4, 6).replaceAll(" ", "")); R = Integer.parseInt(s.substring(10, 13).replaceAll(" ", "")); G = Integer.parseInt(s.substring(14, 17).replaceAll(" ", "")); B = Integer.parseInt(s.substring(18, 21).replaceAll(" ", "")); tit = s.substring(26); System.out.println(tyt+wys+grb+R+G+B); books = addBook(new Book(wys, grb, R, G, B, tyt),books); } file.close(); } catch (IOException e) { //do nothing } }

  • Is it possible to convert a 40-character SHA1 hash to a 20-character SHA1 hash?

    - by ewitch
    My problem is a bit hairy, and I may be asking the wrong questions, so please bear with me... I have a legacy MySQL database which stores the user passwords & salts for a membership system. Both of these values have been hashed using the Ruby framework - roughly like this: hashedsalt = Digest::SHA1.hexdigest("--#{Time.now.to_s}--#{login}--") hashedpassword = Digest::SHA1.hexdigest("#{hashedsalt}:#{password}") So both values are stored as 40-character strings (varchar(40)) in MySQL. Now I need to import all of these users into the ASP.NET membership framework for a new web site, which uses a SQL Server database. It is my understanding that the the way I have ASP.NET membership configured, the user passwords and salts are also stored in the membership database (in table aspnet_Membership) as SHA1 hashes, which are then Base64 encoded (see here for details) and stored as nvarchar(128) data. But from the length of the Base64 encoded strings that are stored (28 characters) it seems that the SHA1 hashes that ASP.NET membership generates are only 20 characters long, rather than 40. From some other reading I have been doing I am thinking this has to do with the number of bits per character/character set/encoding or something related. So is there some way to convert the 40-character SHA1 hashes to 20-character hashes which I can then transfer to the new ASP.NET membership data table? I'm pretty familiar with ASP.NET membership by now but I feel like I'm just missing this one piece. However, it may also be known that SHA1 in Ruby and SHA1 in .NET are incompatible, so I'm fighting a losing battle... Thanks in advance for any insight.

  • How to improve Java performance on Informix for Windows

    - by Michal Niklas
    I have problem with performance of Java UDR functions on Informix on Windows. On this server I already have some functions in C and SPL. I chose one function to write it in those 3 languages and I measured performance of this function on test table. Function calculates some kind of checksum so it does not use any db libraries etc. only string and math operations. I observed performance on 30k records with SQL like: select function(txt) from _tmp_perf_test and I changed function to 'function_c, function_spl or function_java. My performance tests showed that C function is the fastest, SPL function is about 5 times slower, where Java is 100 (one hundred!) times slower than C. I checked it few times and 1:100 ratio didn't improve. I changed Java function to simply return length of the string but even this do not help so it looks, that there is general problem with Java function invocation, because there was no difference in time between Java function that calculate checksum and Java function that returns length of the string. I increased JVM_MAX_HEAP_SIZE to 128 and it not helped too. I use IBM Informix Dynamic Server Version 11.50.TC6DE. The same test on Linux server: IBM Informix Dynamic Server Version 11.50.FC6 show more "normal" results, i.e. Java is slower from C and SPL but only 2 to 5 times. What can I do to improve Java performance on Informix server on Windows?

EDIT: I want to call this function from another place static public String encrypt(String message , String key , int keyLength) throws Exception { // Get the KeyGenerator KeyGenerator kgen = KeyGenerator.getInstance("AES"); kgen.init(keyLength); // 192 and 256 bits may not be available // Generate the secret key specs. //decode the BASE64 coded message SecretKey skey = key; //here is the error raw = skey.getEncoded(); SecretKeySpec skeySpec = new SecretKeySpec(raw, "AES"); // Instantiate the cipher Cipher cipher = Cipher.getInstance("AES"); cipher.init(Cipher.ENCRYPT_MODE, skeySpec); System.out.println("msg is" + message + "\n raw is" + raw); byte[] encrypted = cipher.doFinal(message.getBytes()); String cryptedValue = new String(encrypted); System.out.println("encrypted string: " + cryptedValue); return cryptedValue; } Any one can help, i'll be very thankful.

  • Reading UTF-8 XML and writing it to a file with Python

    - by Harri
    I'm trying to parse UTF-8 XML file and save some parts of it to another file. Problem is, that this is my first Python script ever and I'm totally confused about the character encoding problems I'm finding. My script fails immediately when it tries to write non-ascii character to a file, but it can print it to command prompt (at least in some level) Here's the XML (from the parts that matter at least, it's a *.resx file which contains UI strings) <?xml version="1.0" encoding="utf-8"?> <root> <resheader name="foo"> <value>bar</value> </resheader> <data name="lorem" xml:space="preserve"> <value>ipsum öä</value> </data> </root> And here's my python script from xml.dom.minidom import parse names = [] values = [] def getStrings(path): dom = parse(path) data = dom.getElementsByTagName("data") for i in range(len(data)): name = data[i].getAttribute("name") names.append(name) value = data[i].getElementsByTagName("value") values.append(value[0].firstChild.nodeValue.encode("utf-8")) def writeToFile(): with open("uiStrings-fi.py", "w") as f: for i in range(len(names)): line = names[i] + '="'+ values[i] + '"' #varName='varValue' f.write(line) f.write("\n") getStrings("ResourceFile.fi-FI.resx") writeToFile() And here's the traceback: Traceback (most recent call last): File "GenerateLanguageFiles.py", line 24, in writeToFile() File "GenerateLanguageFiles.py", line 19, in writeToFile line = names[i] + '="'+ values[i] + '"' #varName='varValue' UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 2: ordinal not in ran ge(128) How should I fix my script so it would read and write UTF-8 characters properly? The files I'm trying to generate would be used in test automation with Robots Framework.

  • Encoding h.264 with libavcodec/x264

    - by Leviathan
    I am attempting to encode video using libavcodec/libavformat. I'm trying to change the standard output-example.c from ffmpeg source. The AVI file is created on the disk, but the only sound is encoded. I tried adding a lot of options for x264 from here. All the other codecs works fine, mpeg2, mpeg4, mjpeg, xvid. In addition to specifying the parameters x264, I also set the codec to AVOutputFormat structure. That's all I've done. AVOutputFormat *pOutFormat; // in header file av_register_all(); AVCodec *codec = avcodec_find_encoder_by_name("libx264"); pOutFormat = guess_format("avi", NULL, NULL); pOutFormat->video_codec = codec->id; The debug output of my application: Output #0, mp4, to 'D:\1.avi': Stream #0.0: Video: libx264, yuv420p, 320x240, q=10-51, 500 kb/s, 90k tbn, 25 tbc Stream #0.1: Audio: aac, 44100 Hz, 1 channels, s16, 128 kb/s [libx264 @ 0x694010]using cpu capabilities: MMX2 SSE2Fast SSSE3 FastShuffle SSE4.2 [libx264 @ 0x694010]bitrate tolerance too small, using .01 [libx264 @ 0x694010]profile Main, level 2.0 [libx264 @ 0x694010]frame I:150 Avg QP:14.76 size: 2534 [libx264 @ 0x694010]mb I I16..4: 75.9% 0.0% 24.1% [libx264 @ 0x694010]final ratefactor: 17.57 [libx264 @ 0x694010]coded y,uvDC,uvAC intra: 42.7% 92.4% 47.4% [libx264 @ 0x694010]i16 v,h,dc,p: 11% 14% 2% 73% [libx264 @ 0x694010]i4 v,h,dc,ddl,ddr,vr,hd,vl,hu: 21% 18% 29% 5% 8% 10% 3% 3% 2% [libx264 @ 0x694010]kb/s:506.79

  • Simple in-place discrete fourier transform ( DFT )

    - by Adam
    I'm writing a very simple in-place DFT. I am using the formula shown here: http://en.wikipedia.org/wiki/Discrete_Fourier_transform#Definition along with Euler's formula to avoid having to use a complex number class just for this. So far I have this: private void fft(double[] data) { double[] real = new double[256]; double[] imag = new double[256]; double pi_div_128 = -1 * Math.PI / 128; for (int k = 0; k < 256; k++) { for (int n = 0; n < 256; n++) { real[k] += data[k] * Math.Cos(pi_div_128 * k * n); imag[k] += data[k] * Math.Sin(pi_div_128 * k * n); } data[k] = Math.Sqrt(real[k] * real[k] + imag[k] * imag[k]); } } But the Math.Cos and Math.Sin terms eventually go both positive and negative, so as I'm adding those terms multiplied with data[k], they cancel out and I just get some obscenely small value. I see how it is happening, but I can't make sense of how my code is perhaps mis-representing the mathematics. Any help is appreciated. FYI, I do have to write my own, I realize I can get off-the shelf FFT's.

  • Python unicode problem

    - by Somebody still uses you MS-DOS
    I'm receiving some data from a ZODB (Zope Object Database). I receive a mybrains object. Then I do: o = mybrains.getObject() and I receive a "Person" object in my project. Then, I can do b = o.name and doing print b on my class I get: José Carlos and print b.name.__class__ <type 'unicode'> I have a lot of "Person" objects. They are added to a list. names = [o.nome, o1.nome, o2.nome] Then, I trying to create a text file with this data. delimiter = ';' all = delimiter.join(names) + '\n' No problem. Now, when I do a print all I have: José Carlos;Jonas;Natália Juan;John But when I try to create a file of it: f = open("/tmp/test.txt", "w") f.write(all) I get an error like this (the positions aren't exaclty the same, since I change the names) UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 84: ordinal not in range(128) If I can print already with the "correct" form to display it, why I can't write a file with it? Which encode/decode method should I use to write a file with this data? I'm using Python 2.4.5 (can't upgrade it)

  • Problem with JMX query of Coherence node MBeans visible in JConsole

    - by Quinn Taylor
    I'm using JMX to build a custom tool for monitoring remote Coherence clusters at work. I'm able to connect just fine and query MBeans directly, and I've acquired nearly all the information I need. However, I've run into a snag when trying to query MBeans for specific caches within a cluster, which is where I can find stats about total number of gets/puts, average time for each, etc. The MBeans I'm trying to access programatically are visible when I connect to the remote process using JConsole, and have names like this: Coherence:type=Cache,service=SequenceQueue,name=SEQ%GENERATOR,nodeId=1,tier=back It would make it more flexible if I can dynamically grab all type=Cache MBeans for a particular node ID without specifying all the caches. I'm trying to query them like this: QueryExp specifiedNodeId = Query.eq(Query.attr("nodeId"), Query.value(nodeId)); QueryExp typeIsCache = Query.eq(Query.attr("type"), Query.value("Cache")); QueryExp cacheNodes = Query.and(specifiedNodeId, typeIsCache); ObjectName coherence = new ObjectName("Coherence:*"); Set<ObjectName> cacheMBeans = mBeanServer.queryMBeans(coherence, cacheNodes); However, regardless of whether I use queryMBeans() or queryNames(), the query returns a Set containing... ...0 objects if I pass the arguments shown above ...0 objects if I pass null for the first argument ...all MBeans in the Coherence:* domain (112) if I pass null for the second argument ...every single MBean (128) if I pass null for both arguments The first two results are the unexpected ones, and suggest a problem in the QueryExp I'm passing, but I can't figure out what the problem is. I even tried just passing typeIsCache or specifiedNodeId for the second parameter (with either coherence or null as the first parameter) and I always get 0 results. I'm pretty green with JMX — any insight on what the problem is? (FYI, the monitoring tool will be run on Java 5, so things like JMX 2.0 won't help me at this point.)

  • Setting serial RS232 port settings; any in C# alternatives to SerialPort class ?

    - by adrin
    In my .NET application I need to achieve serial port setup equivalent to this C++ managed code: ::SetCommMask(m_hCOMM, EV_RXCHAR); ::SetupComm(m_hCOMM, 9*2*128*10, 400); ::PurgeComm(m_hCOMM, PURGE_TXABORT|PURGE_RXABORT|PURGE_TXCLEAR|PURGE_RXCLEAR); COMMTIMEOUTS timeOut; timeOut.ReadIntervalTimeout = 3; timeOut.ReadTotalTimeoutConstant = 3; timeOut.ReadTotalTimeoutMultiplier = 1; timeOut.WriteTotalTimeoutConstant = 0; timeOut.WriteTotalTimeoutMultiplier= 0; int nRet= ::SetCommTimeouts(m_hCOMM, &timeOut); ::EscapeCommFunction(m_hCOMM, SETDTR); ::EscapeCommFunction(m_hCOMM, SETRTS); DCB dcb; memset(&dcb, 0, sizeof(DCB)); dcb.BaudRate= m_nSpeed; dcb.ByteSize= 8; dcb.fParity = FALSE; dcb.Parity = NOPARITY; dcb.StopBits= ONESTOPBIT; dcb.fBinary = TRUE; dcb.fDsrSensitivity= FALSE; dcb.fOutxDsrFlow= FALSE; dcb.fOutxCtsFlow= FALSE; dcb.fDtrControl = DTR_CONTROL_HANDSHAKE; dcb.fRtsControl = RTS_CONTROL_TOGGLE; nRet= ::SetCommState(m_hCOMM, &dcb); Is it possible at all? How do I approach this problem? Are there any (preferable free) libraries that allow such low level serial port control or should I create my own wrapper on top of Win32 api? Anyone did anything similar or has an idea how to 'glue' win32 serial port api with .net so that I can use neat .NET DataReceived() events ? Or maybe I can create .NET SerialPort instance and then modify it using managed API?

  • Ruby-on-rails: routing problem: controller action looks for show when it should look for finalize

    - by cbrulak
    background: trying to use the twitter gem for ruby-on-rails. in routes: map.resources :twitter_sessions map.finalize_twitter_sessions 'twitter_sessions/finalize', :controller => 'twitter_sessions', :action => 'finalize' (twitter_sessions is the controller for the twitter sessions in my app). The view has one file new.html.erb and is very simple: <% form_tag(twitter_sessions_path) do |f| %> <p><%= submit_tag "twitter!" %></p> <% end %> and the twitter_sessions_controller.rb: def new end def create oauth.set_callback_url(finalize_twitter_sessions_url) session['rtoken'] = oauth.request_token.token session['rsecret'] = oauth.request_token.secret redirect_to oauth.request_token.authorize_url end def destroy reset_session redirect_to new_session_path end def finalize oauth.authorize_from_request(session['rtoken'], session['rsecret'], params[:oauth_verifier]) profile = Twitter::Base.new(oauth).verify_credentials session['rtoken'] = session['rsecret'] = nil session[:atoken] = oauth.access_token.token session[:asecret] = oauth.access_token.secret sign_in(profile) redirect_back_or root_path end However, after I click the "twitter" button, I get this error: 401 Unauthorized .../gems/oauth-0.3.6/lib/oauth/consumer.rb:200:in `token_request' .../gems/oauth-0.3.6/lib/oauth/consumer.rb:128:in `get_request_token' .../gems/twitter-0.9.2/lib/twitter/oauth.rb:32:in `request_token' .../gems/twitter-0.9.2/lib/twitter/oauth.rb:25:in `set_callback_url' app/controllers/twitter_sessions_controller.rb:7:in `create' If I go to the finalize url, http://localhost:3000/twitter_sessions/finalize, directly, I get this error: Unknown action No action responded to show.
