  • How to convert html textfield/area data to server-side txt file? [closed]

    - by olijake
    How can I make a script that will convert the text/data in a html textfield/textarea and send it to the server, which then saves it as a .txt file for storage? NOTE: I am hosting a website(for testing purposes) using Apache 2.2 on a Windows 7 machine. I downloaded PHP version 5.4.7, but have not yet installed on my server yet (not sure if I will need it, but also not sure how to install it). 1st problem: Saving text to server Html page/section with title textfield, text textarea, and submit button. You would enter a title, the text/notes you need in the textfield, then press the submit button to have it store the text in the textarea, as a .txt file on the server called .txt. 2nd problem: Opening text from server Html with list of all txt files OR textfield for entering in title, then submit button to send the title of the requested .txt file to the server, which would then load it up on the page. Here is what I have so far: (let me know if there is something that I should change or if something just isn't correct in the index.html code I have right now.) <!DOCTYPE HTML> <html> <head> <title>Insert Title</title> <meta http-equiv="Content-Type" content="Text/HTML; charset=UTF-8"/> </head> <body> <form method="post" action="save.INSERT_FILETYPE" name="textfile" enctype="multipart/form-data"> <input type="text" name="title"><br/> <textarea rows="20" cols="100" id="text" name="text"></textarea><br/> <input type="submit" name="submit" value="Submit Text to Server"> </form><br/> <hr style="width: 100%; height: 4px;"><br/> <form method="post" action="open.INSERT_FILETYPE" name="textfile" enctype="multipart/form-data"> <input type="text" name="title"><br/> <input type="submit" name="submit" value="Submit Txt File Request"> </form><br/> <div>Opened text file displays here or goes on another page</div> </body> </html> I plan on using a server side language/script, but ANYTHING that gets the job done is fine. I already tried looking into using some ASP/jScript/PHP, but have had some trouble implementing it into my server. (ie: getting the modules loaded and telling the server what file types to parse.) I know this may be an extremely easy fix, but then in that case, hopefully you wouldn't mind helping me out a little :). If it turns out that this is MUCH more complicated than I expect, then feel free to let me know that, so I don't waste me time running in circles. I appreciate any help/assistance that you can provide, Thanks, Jake EDIT: Wrong Apache version. In response to the comments/closing of this thread: My question: "How exactly do I install the PHP module on the apache server? and is this even possible? and is this even recommended?" ^ In case I wasn't clear enough already To Clarify: I understand the basics of PHP, I just have trouble with INSTALLING PHP on the apache server. (I have used PHP before, but never successfully on apache (so far...)) For my script I wrote something similar to this already (using fopen() and a few other commands): <?php fopen("notes.txt", "r"); file_put_contents("notes.txt",teststring1); ?> I have used javascript for this task before also (although I prefer using PHP and server-side languages): <script language="javascript"> function WriteToFile(){ var fso = new ActiveXObject("Scripting.FileSystemObject"); var s = fso.CreateTextFile("C:\\NewFile.txt", true); var text=document.getElementById("TextArea1").innerText; s.WriteLine(text); s.WriteLine('***********************'); s.Close(); } </script>

  • 500 Internal Server Error with PHP application

    - by James
    I have written a PHP application using Windows and XAMPP. I've been trying to run it on Ubuntu 10.10 with Lighttpd 1.4.26. Parts of the application work fine, but whenever I try to log in, I get a 500 - Internal Server Error page. The only thing that shows up in /var/log/lighttpd/error.log is 2011-02-25 13:43:13: (mod_fastcgi.c.2582) unexpected end-of-file (perhaps the fastcgi process died): pid: 1169 socket: unix:/tmp/php.socket-0 2011-02-25 13:43:13: (mod_fastcgi.c.3367) response not received, request sent: 1596 on socket: unix:/tmp/php.socket-0 for /~denton/customer-facing-portal/index.php?, closing connection If I had any output whatsoever from PHP, this would be a lot easier to debug.

  • Can't log in via SSH to any accounts set to use /bin/bash as a default shell

    - by Gui Ambros
    I'm trying to install bash as the default shell on a ARM Linux running on an embedded device (Synology DS212+ NAS). But there's something really wrong, and I can't figure out what it is. Symptoms: 1) Root has /bin/bash as default shell, and can log in normally via SSH: $ grep root /etc/passwd root:x:0:0:root:/root:/bin/bash $ ssh root@NAS root@NAS's password: Last login: Sun Dec 16 14:06:56 2012 from desktop # 2) joeuser has /bin/bash as default shell, and receives "Permission denied" when trying to log in via SSH: $ grep joeuser /etc/passwd joeuser:x:1029:100:Joe User:/home/joeuser:/bin/bash $ ssh joeuser@localhost joeuser@NAS's password: Last login: Sun Dec 16 14:07:22 2012 from desktop Permission denied, please try again. Connection to localhost closed. 3) changing joeuser's shell back to /bin/sh: $ grep joeuser /etc/passwd joeuser:x:1029:100:Joe User:/home/joeuser:/bin/sh $ ssh joeuser@localhost Last login: Sun Dec 16 15:50:52 2012 from localhost $ To make things even more strange, I can log in as joeuser using /bin/bash using the serial console (!). Also a su - joeuser as root works fine, so the bash binary itself is working fine. In an act of despair, I changed joeuser's uid to 0 on /etc/passwd, but also didn't work, so it doesn't seem to be anything permission related. Seems that bash is doing some extra checking that sshd didn't like, and blocking the connections for non-root users. Maybe some sort of sanity checking - or terminal emulation - that is triggering the SIGCHLD, but only when called via ssh. I already went through every single item on sshd_config, and also put SSHD in debug mode, but didn't find anything strange. Here's my /etc/ssh/sshd_config: LogLevel DEBUG LoginGraceTime 2m PermitRootLogin yes RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys ChallengeResponseAuthentication no UsePAM yes AllowTcpForwarding no ChrootDirectory none Subsystem sftp internal-sftp -f DAEMON -u 000 And here's the output from /usr/syno/sbin/sshd -d, showing the failed attempt of joeuser trying to log in, with /bin/bash as the shell: debug1: Config token is loglevel debug1: Config token is logingracetime debug1: Config token is permitrootlogin debug1: Config token is rsaauthentication debug1: Config token is pubkeyauthentication debug1: Config token is authorizedkeysfile debug1: Config token is challengeresponseauthentication debug1: Config token is usepam debug1: Config token is allowtcpforwarding debug1: Config token is chrootdirectory debug1: Config token is subsystem debug1: HPN Buffer Size: 87380 debug1: sshd version OpenSSH_5.8p1-hpn13v11 debug1: read PEM private key done: type RSA debug1: private host key: #0 type 1 RSA debug1: read PEM private key done: type DSA debug1: private host key: #1 type 2 DSA debug1: read PEM private key done: type ECDSA debug1: private host key: #2 type 3 ECDSA debug1: rexec_argv[0]='/usr/syno/sbin/sshd' debug1: rexec_argv[1]='-d' Set /proc/self/oom_adj from 0 to -17 debug1: Bind to port 22 on ::. debug1: Server TCP RWIN socket size: 87380 debug1: HPN Buffer Size: 87380 Server listening on :: port 22. debug1: Bind to port 22 on 0.0.0.0. debug1: Server TCP RWIN socket size: 87380 debug1: HPN Buffer Size: 87380 Server listening on 0.0.0.0 port 22. debug1: Server will not fork when running in debugging mode. debug1: rexec start in 6 out 6 newsock 6 pipe -1 sock 9 debug1: inetd sockets after dupping: 4, 4 Connection from 127.0.0.1 port 52212 debug1: HPN Disabled: 0, HPN Buffer Size: 87380 debug1: Client protocol version 2.0;

  • VFS: file-max limit 1231582 reached

    - by Rick Koshi
    I'm running a Linux 2.6.36 kernel, and I'm seeing some random errors. Things like ls: error while loading shared libraries: libpthread.so.0: cannot open shared object file: Error 23 Yes, my system can't consistently run an 'ls' command. :( I note several errors in my dmesg output: # dmesg | tail [2808967.543203] EXT4-fs (sda3): re-mounted.

I'm the only one using it, and it's not visible to anyone outside the local network. # lsof | wc 16046 148253 1882901 # ps -ef | wc 574 6104 44260 I saw some documentation saying: file-max & file-nr: The kernel allocates file handles dynamically, but as yet it doesn't free them again. The value in file-max denotes the maximum number of file- handles that the Linux kernel will allocate. When you get lots of error messages about running out of file handles, you might want to increase this limit. Historically, the three values in file-nr denoted the number of allocated file handles, the number of allocated but unused file handles, and the maximum number of file handles. Linux 2.6 always reports 0 as the number of free file handles -- this is not an error, it just means that the number of allocated file handles exactly matches the number of used file handles. Attempts to allocate more file descriptors than file-max are reported with printk, look for "VFS: file-max limit reached". My first reading of this is that the kernel basically has a built-in file descriptor leak, but I find that very hard to believe. It would imply that any system in active use needs to be rebooted every so often to free up the file descriptors. As I said, I can't believe this would be true, since it's normal to me to have Linux systems stay up for months (even years) at a time. On the other hand, I also can't believe that my nearly-idle system is holding over a million files open. Does anyone have any ideas, either for fixes or further diagnosis? I could, of course, just reboot the system, but I don't want this to be a recurring problem every few weeks. As a stopgap measure, I've quit Firefox, which was accounting for almost 2000 lines of lsof output (!) even though I only had one window open, and now I can run 'ls' again, but I doubt that will fix the problem for long. (edit: Oops, spoke too soon. By the time I finished typing out this question, the symptom was/is back) Thanks in advance for any help. And another update: My system was basically unusable, so I decided I had no option but to reboot. But before I did, I carefully quit one process at a time, checking /proc/sys/fs/file-nr after each termination. I found that, predictably, the number of open files gradually went down as I closed things down. Unfortunately, it wasn't a large effect. Yes, I was able to clear up 5000-10000 open files, but there were still over 1.2 million left. I shut down just about everything. All interactive shells, except for the one ssh I left open to finish closing down, httpd, even nfs service. Basically everything in the process table that wasn't a kernel process, and there were still an appalling number of files apparently left open. After the reboot, I found that /proc/sys/fs/file-nr showed about 2000 files open, which is much more reasonable. Starting up 2 Xvnc sessions as usual, along with the dozen or so monitoring windows I like to keep open, brought the total up to about 4000 files. I can see nothing wrong with that, of course, but I've obviously failed to identify the root cause. I'm still looking for ideas, since I definitely expect it to happen again. And another update, the next day: I watched the system carefully, and discovered that /proc/sys/fs/file-nr showed a growth of about 900 open files per hour. I shut down the system's only NFS client for the night, and the growth stopped. Mind you, it didn't free up the resources, but it did at least stop consuming more. Is this a known bug with NFS? I'll be bringing the NFS client back online today, and I'll narrow it down further. If anyone is familiar with this behavior, feel free to jump in with "Yeah, NFS4 has this problem, go back to NFS3" or something like that.

  • RHEL Cluster FAIL after changing time on system

    - by Eugene S
    I've encountered a strange issue. I had to change the time on my Linux RHEL cluster system. I've done it using the following command from the root user: date +%T -s "10:13:13" After doing this, some message appeared relating to <emerg> #1: Quorum Dissolved however I didn't capture it completely. In order to investigate the issue I looked at /var/log/messages and I've discovered the following: Mar 22 16:40:42 hsmsc50sfe1a openais[25715]: [TOTEM] entering GATHER state from 0.

Notice : if there any other commands i should execute in servers for more information, so it might help resolve the problem , let me know in comments

  • CSC folder data access AND roaming profiles issues (Vista with Server 2003, then 2008)

    - by Alex Jones
    I'm a junior sysadmin for an IT contractor that helps small, local government agencies, like little towns and the like. One of our clients, a public library with ~ 50 staff users, was recently migrated from Server 2003 Standard to Server 2008 R2 Standard in a very short timeframe; our senior employee, the only network engineer, had suddenly put in his two weeks notice, so management pushed him to do this project before quitting. A bit hasty on management's part? Perhaps. Could we do anything about that? Nope. Do I have to fix this all by myself? Pretty much. The network is set up like this: a) 50ish staff workstations, all running Vista Business SP2. All staff use MS Outlook, which uses RPC-over-HTTPS ("Outlook Anywhere") for cached Exchange access to an offsite location. b) One new (virtualized) Server 2008 R2 Standard instance, running atop a Server 2008 R2 host via Hyper-V. The VM is the domain's DC, and also the site's one and only file server. Let's call that VM "NEWBOX". c) One old physical Server 2003 Standard server, running the same roles. Let's call it "OLDBOX". It's still on the network and accessible, but it's been demoted, and its shares have been disabled. No data has been deleted. c) Gigabit Ethernet everywhere. The organization's only has one domain, and it did not change during the migration. d) Most users were set up for a combo of redirected folders + offline files, but some older employees who had been with the organization a long time are still on roaming profiles. To sum up: the servers in question handle user accounts and files, nothing else (eg, no TS, no mail, no IIS, etc.) I have two major problems I'm hoping you can help me with: 1) Even though all domain users have had their redirected folders moved to the new server, and loggin in to their workstations and testing confirms that the Documents/Music/Whatever folders point to the new paths, it appears some users (not laptops or anything either!) had been working offline from OLDBOX for a long time, and nobody realized it. Here's the ugly implication: a bunch of their data now lives only in their CSC folders, because they can't access the share on OLDBOX and sync with it finally. How do I get this data out of those CSC folders, and onto NEWBOX? 2) What's the best way to migrate roaming profile users to non-roaming ones, without losing vital data like documents, any lingering PSTs, etc? Things I've thought about trying: For problem 1: a) Reenable the documents share on OLDBOX, force an Offline Files sync for ALL domain users, then copy OLDBOX's share's data to the equivalent share on NEWBOX. Reinitialize the Offline Files cache for every user. With this: How do I safely force a domain-wide Offline Files sync? Could I lose data by reenabling the share on OLDBOX and forcing the sync? Afterwards, how can I reinitialize the Offline Files cache for every user, without doing it manually, workstation by workstation? b) Determine which users have unsynced changes to OLDBOX (again, how?), search each user's CSC folder domain-wide via workstation admin shares, and grab the unsynched data. Reinitialize the Offline Files cache for every user. With this: How can I detect which users have unsynched changes with a script? How can I search each user's CSC folder, when the ownership and permissions set for CSC folders are so restrictive? Again, afterwards, how can I reinitialize the Offline Files cache for every user, without doing it manually, workstation by workstation? c) Manually visit each workstation, copy the contents of the CSC folder, and manually copy that data onto NEWBOX. Reinitialize the Offline Files cache for every user. With this: Again, how do I 'break into' the CSC folder and get to its data? As an experiment, I took one workstation's HD offsite, imaged it for safety, and then tried the following with one of our shop PCs, after attaching the drive: grant myself full control of the folder (failed), grant myself ownership of the folder (failed), run chkdsk on the whole drive to make sure nothing's messed up (all OK), try to take full control of the entire drive (failed), try to take ownership of the entire drive (failed) MS KB articles and Googling around suggests there's a utility called CSCCMD that's meant for this exact scenario...but it looks like it's available for XP, not Vista, no? Again, afterwards, how can I reinitialize the Offline Files cache for every user, without doing it manually, workstation by workstation? For problem 2: a) Figure out which users are on roaming profiles, and where their profiles 'live' on the server. Create new folders for them in the redirected folders repository, migrate existing data, and disable the roaming. With this: Finding out who's roaming isn't hard. But what's the best way to disable the roaming itself? In AD Users and Computers, or on each user's workstation? Doing it centrally on the server seems more efficient; that said, all of the KB research I've done turns up articles on how to go from local to roaming, not the other way around, so I don't have good documentation on this. In closing: we have good backups of NEWBOX and OLDBOX, but not of the workstations themselves, so anything drastic on the client side would need imaging and testing for safety. Thanks for reading along this far! Hopefully you can help me dig us out of this mess.

  • LinkedIn API returns 'Unauthorized' response (PHP OAuth)

    - by Jim Greenleaf
    I've been struggling with this one for a few days now. I've got a test app set up to connect to LinkedIn via OAuth. I want to be able to update a user's status, but at the moment I'm unable to interact with LinkedIn's API at all. I am able to successfully get a requestToken, then an accessToken, but when I issue a request to the API, I see an 'unauthorized' error that looks something like this: object(OAuthException)#2 (8) { ["message:protected"]=> string(73) "Invalid auth/bad request (got a 401, expected HTTP/1.1 20X or a redirect)" ["string:private"]=> string(0) "" ["code:protected"]=> int(401) ["file:protected"]=> string(47) "/home/pmfeorg/public_html/dev/test/linkedin.php" ["line:protected"]=> int(48) ["trace:private"]=> array(1) { [0]=> array(6) { ["file"]=> string(47) "/home/pmfeorg/public_html/dev/test/linkedin.php" ["line"]=> int(48) ["function"]=> string(5) "fetch" ["class"]=> string(5) "OAuth" ["type"]=> string(2) "->" ["args"]=> array(2) { [0]=> string(35) "http://api.linkedin.com/v1/people/~" [1]=> string(3) "GET" } } } ["lastResponse"]=> string(358) " 401 1276375790558 0000 [unauthorized].

  • nhibernate configure and buildsessionfactory time

    - by davidsleeps
    Hi, I'm using Nhibernate as the OR/M tool for an asp.net application and the startup performance is really frustrating. Part of the problem is definitely me in my lack of understanding but I've tried a fair bit (understanding is definitely improving) and am still getting nowhere. Currently ANTS profiler has that the Configure() takes 13-18 seconds and the BuildSessionFActory() as taking about 5 seconds. From what i've read, these times might actually be pretty good, but they were generally talking about hundreds upon hundreds of mapped entities...this project only has 10. I've combined all the mapping files into a single hbm mapping file and this did improve things but only down to the times mentioned above... I guess, are there any "Traps for young players" that are regularly missed...obvious "I did this/have you enabled that/exclude file x/mark file y as z" etc... I'll try the serialize the configuration thing to avoid the Configure() stage, but I feel that part shouldn't be that long for that amount of entities and so would essentially be hiding a current problem... I will post source code or configuration if necessary, but I'm not sure what to put in really... thanks heaps! edit (more info) I'll also add that once this is completed, each page is extremely quick... configuration code- hibernate.cfg.xml <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" /> </configSections> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property> <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property> <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property> <property name="connection.connection_string_name">MyAppDEV</property> <property name="cache.provider_class">NHibernate.Caches.SysCache.SysCacheProvider, NHibernate.Caches.SysCache</property> <property name="cache.use_second_level_cache">true</property> <property name="show_sql">false</property> <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property> <property name="current_session_context_class">managed_web</property> <mapping assembly="MyApp.Domain"/> </session-factory> </hibernate-configuration> </configuration> My SessionManager class which is bound and unbound in a HttpModule for each request Imports NHibernate Imports NHibernate.Cfg Public Class SessionManager Private ReadOnly _sessionFactory As ISessionFactory Public Shared ReadOnly Property SessionFactory() As ISessionFactory Get Return Instance._sessionFactory End Get End Property Private Function GetSessionFactory() As ISessionFactory Return _sessionFactory End Function Public Shared ReadOnly Property Instance() As SessionManager Get Return NestedSessionManager.theSessionManager End Get End Property Public Shared Function OpenSession() As ISession Return Instance.GetSessionFactory().OpenSession() End Function Public Shared ReadOnly Property CurrentSession() As ISession Get Return Instance.GetSessionFactory().GetCurrentSession() End Get End Property Private Sub New() Dim configuration As Configuration = New Configuration().Configure() _sessionFactory = configuration.BuildSessionFactory() End Sub Private Class NestedSessionManager Friend Shared ReadOnly theSessionManager As New SessionManager() End Class End Class edit 2 (log4net results) will post bits that have a portion of time between them and will cut out the rest... 2010-03-30 23:29:40,898 [4] INFO NHibernate.Cfg.Environment [(null)] - Using reflection optimizer 2010-03-30 23:29:42,481 [4] DEBUG NHibernate.Cfg.Configuration [(null)] - dialect=NHibernate.Dialect.MsSql2005Dialect ... 2010-03-30 23:29:42,501 [4] INFO NHibernate.Cfg.Configuration [(null)] - Mapping resource: MyApp.Domain.Mappings.hbm.xml 2010-03-30 23:29:43,342 [4] INFO NHibernate.Dialect.Dialect [(null)] - Using dialect: NHibernate.Dialect.MsSql2005Dialect 2010-03-30 23:29:50,462 [4] INFO NHibernate.Cfg.XmlHbmBinding.Binder [(null)] - Mapping class: ... 2010-03-30 23:29:51,353 [4] DEBUG NHibernate.Connection.DriverConnectionProvider [(null)] - Obtaining IDbConnection from Driver 2010-03-30 23:29:53,136 [4] DEBUG NHibernate.Connection.ConnectionProvider [(null)] - Closing connection

  • JMS ConnectionFactory creation error WSVR0073W

    I must confess I’m not a JMS aficionado, one of our guys has written a Java webservice client [postcode lookup web service] and from a Remote Java client are calling a Message Driven Bean running in Websphere 6.1, using JMS.

  • WFP: How do you properly Bind a DependencyProperty to the GUI

    - by Robert Ross
    I have the following class (abreviated for simplicity). The app it multi-threaded so the Set and Get are a bit more complicated but should be ok. namespace News.RSS { public class FeedEngine : DependencyObject { public static readonly DependencyProperty _processing = DependencyProperty.Register("Processing", typeof(bool), typeof(FeedEngine), new FrameworkPropertyMetadata(true, FrameworkPropertyMetadataOptions.AffectsRender)); public bool Processing { get { return (bool)this.Dispatcher.Invoke( DispatcherPriority.Normal, (DispatcherOperationCallback)delegate { return GetValue(_processing); }, Processing); } set { this.Dispatcher.BeginInvoke(DispatcherPriority.Normal, (SendOrPostCallback)delegate { SetValue(_processing, value); }, value); } } public void Poll() { while (Running) { Processing = true; //Do my work to read the data feed from remote source Processing = false; Thread.Sleep(PollRate); } // } } } Next I have my main form as the following: <Window x:Class="News.Main" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:converter="clr-namespace:News.Converters" xmlns:local="clr-namespace:News.Lookup" xmlns:rss="clr-namespace:News.RSS" Title="News" Height="521" Width="927" Initialized="Window_Initialized" Closing="Window_Closing" > <Window.Resources> <ResourceDictionary> <converter:BooleanConverter x:Key="boolConverter" /> <converter:ArithmeticConverter x:Key="arithConverter" /> ... </ResourceDictionary> </Window.Resources> <DockPanel Name="dockPanel1" SnapsToDevicePixels="False" > <ToolBarPanel Height="37" Name="toolBarPanel" Orientation="Horizontal" DockPanel.Dock="Top" > <ToolBarPanel.Children> <Button DataContext="{DynamicResource FeedEngine}" HorizontalAlignment="Right" Name="btnSearch" ToolTip="Search" Click="btnSearch_Click" IsEnabled="{Binding Path=Processing, Converter={StaticResource boolConverter}}"> <Image Width="32" Height="32" Name="imgSearch" Source="{Resx ResxName=News.Properties.Resources, Key=Search}" /> </Button> ... </DockPanel> </Window> As you can see I set the DataContext to FeedEngine and Bind IsEnabled to Processing. I have also tested the boolConverter separately and it functions (just applies ! (Not) to a bool). Here is my Main window code behind in case it helps to debug. namespace News { /// <summary> /// Interaction logic for Main.xaml /// </summary> public partial class Main : Window { public FeedEngine _engine; List<NewsItemControl> _newsItems = new List<NewsItemControl>(); Thread _pollingThread; public Main() { InitializeComponent(); this.Show(); } private void Window_Initialized(object sender, EventArgs e) { // Load current Feed data. _engine = new FeedEngine(); ThreadStart start = new ThreadStart(_engine.Poll); _pollingThread = new Thread(start); _pollingThread.Start(); } } } Hope someone can see where I missed a step. Thanks.

  • Apple push Notification Feedback service Not working

    - by Yassmeen
    Hi, I am developing an iPhone App that uses Apple Push Notifications. On the iPhone side everything is fine, on the server side I have a problem. Notifications are sent correctly however when I try to query the feedback service to obtain a list of devices from which the App has been uninstalled, I always get zero results. I know that I should obtain one result as the App has been uninstalled from one of my test devices. After 24 hours and more I still have no results from the feedback service.. Any ideas? Does anybody know how long it takes for the feedback service to recognize that my App has been uninstalled from my test device? Note: I have another push notification applications on the device so I know that my app is not the only app. The code - C#: public static string CheckFeedbackService(string certaName, string hostName) { SYLogger.Log("Check Feedback Service Started"); ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateServerCertificate); // Create a TCP socket connection to the Apple server on port 2196 TcpClient tcpClientF = null; SslStream sslStreamF = null; string result = string.Empty; //Contect to APNS& Add the Apple cert to our collection X509Certificate2Collection certs = new X509Certificate2Collection { GetServerCert(certaName) }; //Set up byte[] buffer = new byte[38]; int recd = 0; DateTime minTimestamp = DateTime.Now.AddYears(-1); // Create a TCP socket connection to the Apple server on port 2196 try { using (tcpClientF = new TcpClient(hostName, 2196)) { SYLogger.Log("Client Connected ::" + tcpClientF.Connected); // Create a new SSL stream over the connection sslStreamF = new SslStream(tcpClientF.GetStream(), true,ValidateServerCertificate); // Authenticate using the Apple cert sslStreamF.AuthenticateAsClient(hostName, certs, SslProtocols.Default, false); SYLogger.Log("Stream Readable ::" + sslStreamF.CanRead); SYLogger.Log("Host Name ::"+hostName); SYLogger.Log("Cert Name ::" + certs[0].FriendlyName); if (sslStreamF != null) { SYLogger.Log("Connection Started"); //Get the first feedback recd = sslStreamF.Read(buffer, 0, buffer.Length); SYLogger.Log("Buffer length ::" + recd); //Continue while we have results and are not disposing while (recd > 0) { SYLogger.Log("Reading Started"); //Get our seconds since 1970 ? byte[] bSeconds = new byte[4]; byte[] bDeviceToken = new byte[32]; Array.Copy(buffer, 0, bSeconds, 0, 4); //Check endianness if (BitConverter.IsLittleEndian) Array.Reverse(bSeconds); int tSeconds = BitConverter.ToInt32(bSeconds, 0); //Add seconds since 1970 to that date, in UTC and then get it locally var Timestamp = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc).AddSeconds(tSeconds).ToLocalTime(); //Now copy out the device token Array.Copy(buffer, 6, bDeviceToken, 0, 32); string deviceToken = BitConverter.ToString(bDeviceToken).Replace("-", "").ToLower().Trim(); //Make sure we have a good feedback tuple if (deviceToken.Length == 64 && Timestamp > minTimestamp) { SYLogger.Log("Feedback " + deviceToken); result = deviceToken; } //Clear array to reuse it Array.Clear(buffer, 0, buffer.Length); //Read the next feedback recd = sslStreamF.Read(buffer, 0, buffer.Length); } SYLogger.Log("Reading Ended"); } } } catch (Exception e) { SYLogger.Log("Authentication failed - closing the connection::" + e); return "NOAUTH"; } finally { // The client stream will be closed with the sslStream // because we specified this behavior when creating the sslStream. if (sslStreamF != null) sslStreamF.Close(); if (tcpClientF != null) tcpClientF.Close(); //Clear array on error Array.Clear(buffer, 0, buffer.Length); } SYLogger.Log("Feedback ended "); return result; }

  • Flex SDK missing fundamental things

    - by Bart van Heukelom
    All of a sudden Flash Builder 4 is missing all kinds of fundamental things and is generating incorrect errors. I've had the same issue yesterday, where I fixed it by downloading a new Flex SDK and importing that into FB. I did this again, but this time it fixed nothing. I don't think it's something I did, like removing critical references from the build path. The errors also appeared on projects I was not working on at the time. It occurs for ActionScript, Flex and Flex Library projects alike. Update 3: Well, i've singled the problem down to a single piece of code, though a very simple one. I can make a new workspace in FB and things work ok, then screw the workspace up forever by adding this code to a project. All projects will have errors and closing or even removing the faulty project does not change this. Making another new workspace (without the faulty code) makes my projects compile again. Link: http://www.the3rdage.net/files/2745/Main.as (i've uploaded the file in case an odd character or encoding error causes the error) Update 2: I've tried manual compiling with mxmlc, the same errors occur. It appears to be an SDK problem, not Flash Builder. Update: I find this stack trace in the Flash Builder error log: !ENTRY com.adobe.flexbuilder.project 4 43 2010-05-11 11:55:47.495 !MESSAGE Uncaught exception in compiler !STACK 0 java.lang.NullPointerException at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2592) at macromedia.asc.parser.VariableBindingNode.evaluate(VariableBindingNode.java:64) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2233) at macromedia.asc.parser.ListNode.evaluate(ListNode.java:44) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2578) at macromedia.asc.parser.VariableDefinitionNode.evaluate(VariableDefinitionNode.java:48) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2310) at macromedia.asc.parser.StatementListNode.evaluate(StatementListNode.java:60) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2503) at macromedia.asc.parser.WithStatementNode.evaluate(WithStatementNode.java:44) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2310) at macromedia.asc.parser.StatementListNode.evaluate(StatementListNode.java:60) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2891) at macromedia.asc.parser.FunctionCommonNode.evaluate(FunctionCommonNode.java:106) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:2905) at macromedia.asc.parser.FunctionCommonNode.evaluate(FunctionCommonNode.java:106) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:3643) at macromedia.asc.parser.ClassDefinitionNode.evaluate(ClassDefinitionNode.java:106) at macromedia.asc.semantics.ConstantEvaluator.evaluate(ConstantEvaluator.java:3371) at macromedia.asc.parser.ProgramNode.evaluate(ProgramNode.java:80) at flex2.compiler.as3.As3Compiler.analyze4(As3Compiler.java:709) at flex2.compiler.CompilerAPI.analyze(CompilerAPI.java:3089) at flex2.compiler.CompilerAPI.analyze(CompilerAPI.java:2977) at flex2.compiler.CompilerAPI.batch2(CompilerAPI.java:528) at flex2.compiler.CompilerAPI.batch(CompilerAPI.java:1274) at flex2.compiler.CompilerAPI.compile(CompilerAPI.java:1496) at flex2.tools.oem.Application.compile(Application.java:1188) at flex2.tools.oem.Application.recompile(Application.java:1133) at flex2.tools.oem.Application.compile(Application.java:819) at flex2.tools.flexbuilder.BuilderApplication.compile(BuilderApplication.java:344) at com.adobe.flexbuilder.multisdk.compiler.internal.ASApplicationBuilder$MyBuilder.mybuild(ASApplicationBuilder.java:276) at com.adobe.flexbuilder.multisdk.compiler.internal.ASApplicationBuilder.build(ASApplicationBuilder.java:127) at com.adobe.flexbuilder.multisdk.compiler.internal.ASBuilder.build(ASBuilder.java:190) at com.adobe.flexbuilder.multisdk.compiler.internal.ASItemBuilder.build(ASItemBuilder.java:74) at com.adobe.flexbuilder.project.compiler.internal.FlexProjectBuilder.buildItem(FlexProjectBuilder.java:480) at com.adobe.flexbuilder.project.compiler.internal.FlexProjectBuilder.build(FlexProjectBuilder.java:306) at com.adobe.flexbuilder.project.compiler.internal.FlexIncrementalBuilder.build(FlexIncrementalBuilder.java:157) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:627) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:170) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:201) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:253) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:256) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:309) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:341) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:140) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:238) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)

  • Linq to SQL NullReferenceException's: A random needle in a haystack!

    - by Shane
    I'm getting NullReferenceExeceptions at seemly random times in my application and can't track down what could be causing the error. I'll do my best to describe the scenario and setup. Any and all suggestions greatly appreciated! C# .net 3.5 Forms Application, but I use the WebFormRouting library built by Phil Haack (http://haacked.com/archive/2008/03/11/using-routing-with-webforms.aspx) to leverage the Routing libraries of .net (usually used in conjunction with MVC) - intead of using url rewriting for my urls. My database has 60 tables. All Normalized. It's just a massive application. (SQL server 2008) All queries are built with Linq to SQL in code (no SP's). Each time a new instance of my data context is created. I use only one data context with all relationships defined in 4 relationship diagrams in SQL Server. the data context gets created a lot. I let the closing of the data context be handled automatically. I've heard arguments both sides about whether you should leave to be closed automatically or do it yourself. In this case I do it myself. It doesnt seem to matter if I'm creating a lot of instances of the data context or just one. For example, I've got a vote-up button. with the following code, and it errors probably 1 in 10-20 times. protected void VoteUpLinkButton_Click(object sender, EventArgs e) { DatabaseDataContext db = new DatabaseDataContext(); StoryVote storyVote = new StoryVote(); storyVote.StoryId = storyId; storyVote.UserId = Utility.GetUserId(Context); storyVote.IPAddress = Utility.GetUserIPAddress(); storyVote.CreatedDate = DateTime.Now; storyVote.IsDeleted = false; db.StoryVotes.InsertOnSubmit(storyVote); db.SubmitChanges(); // If this story is not yet published, check to see if we should publish it. Make sure that // it is already approved. if (story.PublishedDate == null && story.ApprovedDate != null) { Utility.MakeUpcommingNewsPopular(storyId); } // Refresh our page. Response.Redirect("/news/" + category.UniqueName + "/" + RouteData.Values["year"].ToString() + "/" + RouteData.Values["month"].ToString() + "/" + RouteData.Values["day"].ToString() + "/" + RouteData.Values["uniquename"].ToString()); } The last thing I tried was the "Auto Close" flag setting on SQL Server. This was set to true and I changed to false. Doesnt seem to have done the trick although has had a good overall effect. Here's a detailed that wasnt caught. I also get slighly different errors when caught by my try/catch's. System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. --- System.NullReferenceException: Object reference not set to an instance of an object. at System.Web.Util.StringUtil.GetStringHashCode(String s) at System.Web.UI.ClientScriptManager.EnsureEventValidationFieldLoaded() at System.Web.UI.ClientScriptManager.ValidateEvent(String uniqueId, String argument) at System.Web.UI.WebControls.TextBox.LoadPostData(String postDataKey, NameValueCollection postCollection) at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) --- End of inner exception stack trace --- at System.Web.UI.Page.HandleError(Exception e) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) at System.Web.UI.Page.ProcessRequest() at System.Web.UI.Page.ProcessRequest(HttpContext context) at ASP.forms_news_detail_aspx.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) HELP!!!

  • OSX: How to get a volume name (or bsd name) from a IOUSBDeviceInterface or location id

    - by LG
    Hi, I'm trying to write an app that associates a particular USB string descriptor (of a USB mass storage device) with its volume or bsd name. So the code goes through all the connected USB devices, gets the string descriptors and extracts information from one of them. I would like to get the volume name of those USB devices. I can't find the right API to do that. I have tried to do that: DASessionRef session = DASessionCreate(kCFAllocatorDefault); DADiskRef disk_ref = DADiskCreateFromIOMedia(kCFAllocatorDefault, session, usb_device_ref); const char* name = DADiskGetBSDName(disk_ref); But the DADiskCreateFromIOMedia function returned nil, I assume the usb_device_ref that I passed was not compatible with the io_service_t that the function is expecting. So how can I get the volume name of a USB device? Could I use the location id to do that? Thanks for reading. -L FOO_Result result = FOO_SUCCESS; mach_port_t master_port; kern_return_t k_result; io_iterator_t iterator = 0; io_service_t usb_device_ref; CFMutableDictionaryRef matching_dictionary = NULL; // first create a master_port if (FOO_FAILED(k_result = IOMasterPort(MACH_PORT_NULL, &master_port))) { fprintf(stderr, "could not create master port, err = %d\n", k_result); goto cleanup; } if ((matching_dictionary = IOServiceMatching(kIOUSBDeviceClassName)) == NULL) { fprintf(stderr, "could not create matching dictionary, err = %d\n", k_result); goto cleanup; } if (FOO_FAILED(k_result = IOServiceGetMatchingServices(master_port, matching_dictionary, &iterator))) { fprintf(stderr, "could not find any matching services, err = %d\n", k_result); goto cleanup; } while (usb_device_ref = IOIteratorNext(iterator)) { IOReturn err; IOCFPlugInInterface **iodev; // requires <IOKit/IOCFPlugIn.h> IOUSBDeviceInterface **dev; SInt32 score; err = IOCreatePlugInInterfaceForService(usb_device_ref, kIOUSBDeviceUserClientTypeID, kIOCFPlugInInterfaceID, &iodev, &score); if (err || !iodev) { printf("dealWithDevice: unable to create plugin. ret = %08x, iodev = %p\n", err, iodev); return; } err = (*iodev)->QueryInterface(iodev, CFUUIDGetUUIDBytes(kIOUSBDeviceInterfaceID), (LPVOID*)&dev); (*iodev)->Release(iodev); // done with this FOO_String string_value; UInt8 string_index = 0x1; FOO_Result result = FOO_SUCCESS; CFStringRef device_name_as_cf_string; do { if (FOO_SUCCEEDED(result = FOO_GetStringDescriptor(dev, string_index, 0, string_value))) { printf("String at index %i is %s\n", string_index, string_value.GetChars()); // extract the command code if it is the FOO string if (string_value.CompareN("FOO:", 4) == 0) { FOO_Byte code = 0; FOO_HexToByte(string_value.GetChars() + 4, code); // Get other relevant information from the device io_name_t device_name; UInt32 location_id = 0; // Get the USB device's name. err = IORegistryEntryGetName(usb_device_ref, device_name); device_name_as_cf_string = CFStringCreateWithCString(kCFAllocatorDefault, device_name, kCFStringEncodingASCII); err = (*dev)->GetLocationID(dev, &location_id); // TODO: get volume or BSD name // add the device to the list break; } } string_index++; } while (FOO_SUCCEEDED(result)); err = (*dev)->USBDeviceClose(dev); if (err) { printf("dealWithDevice: error closing device - %08x\n", err); (*dev)->Release(dev); return; } err = (*dev)->Release(dev); if (err) { printf("dealWithDevice: error releasing device - %08x\n", err); return; } IOObjectRelease(usb_device_ref); // no longer need this reference }

  • wpf exit thread automatically when application closes

    - by toni
    Hi, I have a main wpf window and one of its controls is a user control that I have created. this user control is an analog clock and contains a thread that update hour, minute and second hands. Initially it wasn't a thread, it was a timer event that updated the hour, minutes and seconds but I have changed it to a thread because the application do some hard work when the user press a start button and then the clock don't update so I changed it to a thread. COde snippet of wpf window: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:GParts" xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes assembly=PresentationFramework.Aero" xmlns:UC="clr-namespace:GParts.UserControls" x:Class="GParts.WinMain" Title="GParts" WindowState="Maximized" Closing="Window_Closing" Icon="/Resources/Calendar-clock.png" x:Name="WMain" > <...> <!-- this is my user control --> <UC:AnalogClock Grid.Row="1" x:Name="AnalogClock" Background="Transparent" Margin="0" Height="Auto" Width="Auto"/> <...> </Window> My problem is when the user exits the application then the thread seems to continue executing. I would like the thread finishes automatically when main windows closes. code snippet of user control constructor: namespace GParts.UserControls { /// <summary> /// Lógica de interacción para AnalogClock.xaml /// </summary> public partial class AnalogClock : UserControl { System.Timers.Timer timer = new System.Timers.Timer(1000); public AnalogClock() { InitializeComponent(); MDCalendar mdCalendar = new MDCalendar(); DateTime date = DateTime.Now; TimeZone time = TimeZone.CurrentTimeZone; TimeSpan difference = time.GetUtcOffset(date); uint currentTime = mdCalendar.Time() + (uint)difference.TotalSeconds; christianityCalendar.Content = mdCalendar.Date("d/e/Z", currentTime, false); // this was before implementing thread //timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed); //timer.Enabled = true; // The Work to perform ThreadStart start = delegate() { // With this condition the thread exits when main window closes but // despite of this it seems like the thread continues executing after // exiting application because in task manager cpu is very busy // while ((this.IsInitialized) && (this.Dispatcher.HasShutdownFinished== false)) { this.Dispatcher.Invoke(DispatcherPriority.Normal, (Action)(() => { DateTime hora = DateTime.Now; secondHand.Angle = hora.Second * 6; minuteHand.Angle = hora.Minute * 6; hourHand.Angle = (hora.Hour * 30) + (hora.Minute * 0.5); DigitalClock.CurrentTime = hora; })); } Console.Write("Quit ok"); }; // Create the thread and kick it started! new Thread(start).Start(); } // this was before implementing thread void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { this.Dispatcher.Invoke(DispatcherPriority.Normal, (Action)(() => { DateTime hora = DateTime.Now; secondHand.Angle = hora.Second * 6; minuteHand.Angle = hora.Minute * 6; hourHand.Angle = (hora.Hour * 30) + (hora.Minute * 0.5); DigitalClock.CurrentTime = hora; })); } } // end class } // end namespace How can I exit correctly from thread automatically when main window closes and then application exits?

  • How do I make this scroll layout work?

    - by JuiCe
    I am currently trying to get my UI to have a Title Bar, a bottom Button bar, with a ScrollView in between.

  • surfaceDestroyed called out of turn

    - by Avasulthiris
    I'm currently developing on minimum sdk version 3 (Android 1.5 - cupcake) and I'm having a strange unexplained issue that I have not been able to solve on my own. It is now becoming a rather urgent issue as I've already missed 1 deadline... I'm writing a high-level library to make long term android development easier and quicker. The one specific module has to capture images for a application... I've gotten everything right so far over the last couple months, except this one little thing and I don't know what to do any more: When I use the Camera object and implement a SurfaceHolder.Callback, the methods surfaceCreated() and surfaceChanged() are called one after the other. Then when the activity finishes, surfaceDestroyed() is called. This is how it should be, but when I stick the exact same code in my library (plain Java library that references the Android API - not in an activity), surfaceDestroyed() is called directly after created and changed. As a result - the camera object is closed before I can use it and the application force closes. What a pain. I can't do anything! This method call is controlled by the device.. Why does the surface close for no reason? Even when I post it to run on the activity thread through my own invokeAndWait(Runnable) method, like I do for many other things. I have 5 different working examples of different ways and implementations of capturing images in android but I still get the same issue when I plug it into my library. I don't understand what the difference is. The code is pretty much the same - and I post all the related code to the UI thread so its not a thread handling issue or anything like that. I've rewritten it about 20 times in different ways - same issue every time.. The only other way to approach it that I know of is creating a new Camera and setting it to the VideoView. The android source (c++ native code) however provides no Camera constructor, only an open() method which automatically forwards the camera's state to 'prepared' but I can only set the camera to the VideoView from the 'initialized' state. Pretty silly, I know, but there is no way around it unless I modify the Android library source code haha. not an option! The API does not allow for this method - you are expected to use it like my first example. So essentially - i just need to understand exactly why surfaceDestroyed() is called out of turn and if there is anything I can do to avoid it closing? If i can just understand the exact logic behind it and how it works! The documentation isn't much help! Secondly, if someone knows of any alternative ways to do it, as my second example, but hopefully one which the API actually allows for? haha Thanks guys. I would post code, but its fairly complicated, a couple thousand lines for this specific class and it would probably take a couple days to explain with all the threading and event listeners and what not. I just need help with this 1 single thing. Please let me know if you have any questions.

  • Mysql 100% CPU + Slow query

    - by felipeclopes
    I'm using the RDS database from amazon with a some very big tables, and yesterday I started to face 100% CPU utilisation on the server and a bunch of slow query logs that were not happening before. I tried to check the queries that were running and faced this result from the explain command +----+-------------+-------------------------------+--------+----------------------------------------------------------------------------------------------+---------------------------------------+---------+-----------------------------------------------------------------+------+----------------------------------------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------------------------------+--------+----------------------------------------------------------------------------------------------+---------------------------------------+---------+-----------------------------------------------------------------+------+----------------------------------------------+ | 1 | SIMPLE | businesses | const | PRIMARY | PRIMARY | 4 | const | 1 | Using index; Using temporary; Using filesort | | 1 | SIMPLE | activities_businesses | ref | PRIMARY,index_activities_users_on_business_id,index_tweets_users_on_tweet_id_and_business_id | index_activities_users_on_business_id | 9 | const | 2252 | Using index condition; Using where | | 1 | SIMPLE | activities_b_taggings_975e9c4 | ref | taggings_idx | taggings_idx | 782 | const,myapp_production.activities_businesses.id,const | 1 | Using index condition; Using where | | 1 | SIMPLE | activities | eq_ref | PRIMARY,index_activities_on_created_at | PRIMARY | 8 | myapp_production.activities_businesses.activity_id | 1 | Using where | +----+-------------+-------------------------------+--------+----------------------------------------------------------------------------------------------+---------------------------------------+---------+-----------------------------------------------------------------+------+----------------------------------------------+ Also checkin in the process list, I got something like this: +----+-----------------+-------------------------------------+----------------------------+---------+------+--------------+------------------------------------------------------------------------------------------------------+ | Id | User | Host | db | Command | Time | State | Info | +----+-----------------+-------------------------------------+----------------------------+---------+------+--------------+------------------------------------------------------------------------------------------------------+ | 1 | my_app | my_ip:57152 | my_app_production | Sleep | 0 | | NULL | | 2 | my_app | my_ip:57153 | my_app_production | Sleep | 2 | | NULL | | 3 | rdsadmin | localhost:49441 | NULL | Sleep | 9 | | NULL | | 6 | my_app | my_other_ip:47802 | my_app_production | Sleep | 242 | | NULL | | 7 | my_app | my_other_ip:47807 | my_app_production | Query | 231 | Sending data | SELECT my_fields... | | 8 | my_app | my_other_ip:47809 | my_app_production | Query | 231 | Sending data | SELECT my_fields... | | 9 | my_app | my_other_ip:47810 | my_app_production | Query | 231 | Sending data | SELECT my_fields... | | 10 | my_app | my_other_ip:47811 | my_app_production | Query | 231 | Sending data | SELECT my_fields... | | 11 | my_app | my_other_ip:47813 | my_app_production | Query | 231 | Sending data | SELECT my_fields... | ...

Do you guys can help m with that?

  • Connecting Android device to multiple Bluetooth serial embedded peers

    - by TacB0sS
    I'm trying to find a solution for this setup: I have a single Android device, which I would like to connect to multiple serial embedded devices... And here is the thing, using the "Normal" way to retrieve the Bluetooth socket, doesn't work on all devices, and while it does, I can connect to multiple devices, and send and receive data to and from multiple devices. public final synchronized void connect() throws ConnectionException { if (socket != null) throw new IllegalStateException("Error socket is not null!!"); connecting = true; lastException = null; lastPacket = null; lastHeartBeatReceivedAt = 0; log.setLength(0); try { socket = fetchBT_Socket_Normal(); connectToSocket(socket); listenForIncomingSPP_Packets(); connecting = false; return; } catch (Exception e) { socket = null; logError(e); } try { socket = fetchBT_Socket_Workaround(); connectToSocket(socket); listenForIncomingSPP_Packets(); connecting = false; return; } catch (Exception e) { socket = null; logError(e); } connecting = false; if (socket == null) throw new ConnectionException("Error creating RFcomm socket for" + this); } private BluetoothSocket fetchBT_Socket_Normal() throws Exception { /* The getType() is a hex 0xXXXX value agreed between peers --- this is the key (in my case) to multiple connections in the "Normal" way */ String uuid = getType() + "1101-0000-1000-8000-00805F9B34FB"; try { logDebug("Fetching BT RFcomm Socket standard for UUID: " + uuid + "..."); socket = btDevice.createRfcommSocketToServiceRecord(UUID.fromString(uuid)); return socket; } catch (Exception e) { logError(e); throw e; } } private BluetoothSocket fetchBT_Socket_Workaround() throws Exception { Method m; int connectionIndex = 1; try { logDebug("Fetching BT RFcomm Socket workaround index " + connectionIndex + "..."); m = btDevice.getClass().getMethod("createRfcommSocket", new Class[]{int.class}); socket = (BluetoothSocket) m.invoke(btDevice, connectionIndex); return socket; } catch (Exception e1) { logError(e1); throw e1; } } private void connectToSocket(BluetoothSocket socket) throws ConnectionException { try { socket.connect(); } catch (IOException e) { try { socket.close(); } catch (IOException e1) { logError("Error while closing socket", e1); } finally { socket = null; } throw new ConnectionException("Error connecting to socket with" + this, e); } } And here is the thing, while on phones which the "Normal" way doesn't work, the "Workaround" way provides a solution for a single connection. I've searched far and wide, but came up with zip. The problem with the workaround is mentioned in the last link, both connection uses the same port, which in my case, causes a block, where both of the embedded devices can actually send data, that is not been processed on the Android, while both embedded devices can receive data sent from the Android. Did anyone handle this before? There is a bit more reference here, UPDATE: Following this (that I posted earlier) I wanted to give the mPort a chance, and perhaps to see other port indices, and how other devices manage them, and I found out the the fields in the BluetoothSocket object are different while it is the same class FQN in both cases: Detils from an HTC Vivid 2.3.4, uses the "workaround" Technic: The Socket class type is: [android.bluetooth.BluetoothSocket] mSocket BluetoothSocket (id=830008629928) EADDRINUSE 98 EBADFD 77 MAX_RFCOMM_CHANNEL 30 TAG "BluetoothSocket" (id=830002722432) TYPE_L2CAP 3 TYPE_RFCOMM 1 TYPE_SCO 2 mAddress "64:9C:8E:DC:56:9A" (id=830008516328) mAuth true mClosed false mClosing AtomicBoolean (id=830007851600) mDevice BluetoothDevice (id=830007854256) mEncrypt true mInputStream BluetoothInputStream (id=830008688856) mLock ReentrantReadWriteLock (id=830008629992) mOutputStream BluetoothOutputStream (id=830008430536) **mPort 1** mSdp null mSocketData 3923880 mType 1 Detils from an LG-P925 2.2.2, uses the "normal" Technic: The Socket class type is: [android.bluetooth.BluetoothSocket] mSocket BluetoothSocket (id=830105532880) EADDRINUSE 98 EBADFD 77 MAX_RFCOMM_CHANNEL 30 TAG "BluetoothSocket" (id=830002668088) TYPE_L2CAP 3 TYPE_RFCOMM 1 TYPE_SCO 2 mAccepted false mAddress "64:9C:8E:B9:3F:77" (id=830105544600) mAuth true mClosed false mConnected ConditionVariable (id=830105533144) mDevice BluetoothDevice (id=830105349488) mEncrypt true mInputStream BluetoothInputStream (id=830105532952) mLock ReentrantReadWriteLock (id=830105532984) mOutputStream BluetoothOutputStream (id=830105532968) mPortName "" (id=830002606256) mSocketData 0 mSppPort BluetoothSppPort (id=830105533160) mType 1 mUuid ParcelUuid (id=830105714176) Anyone have some insight...

  • Why might a System.String object not cache its hash code?

    - by Dan Tao
    A glance at the source code for string.GetHashCode using Reflector reveals the following (for mscorlib.dll version 4.0): public override unsafe int GetHashCode() { fixed (char* str = ((char*) this)) { char* chPtr = str; int num = 0x15051505; int num2 = num; int* numPtr = (int*) chPtr; for (int i = this.Length; i > 0; i -= 4) { num = (((num << 5) + num) + (num >> 0x1b)) ^ numPtr[0]; if (i <= 2) { break; } num2 = (((num2 << 5) + num2) + (num2 >> 0x1b)) ^ numPtr[1]; numPtr += 2; } return (num + (num2 * 0x5d588b65)); } } Now, I realize that the implementation of GetHashCode is not specified and is implementation-dependent, so the question "is GetHashCode implemented in the form of X or Y?" is not really answerable. I'm just curious about a few things: If Reflector has disassembled the DLL correctly and this is the implementation of GetHashCode (in my environment), am I correct in interpreting this code to indicate that a string object, based on this particular implementation, would not cache its hash code? Assuming the answer is yes, why would this be? It seems to me that the memory cost would be minimal (one more 32-bit integer, a drop in the pond compared to the size of the string itself) whereas the savings would be significant, especially in cases where, e.g., strings are used as keys in a hashtable-based collection like a Dictionary<string, [...]>. And since the string class is immutable, it isn't like the value returned by GetHashCode will ever even change. What could I be missing? UPDATE: In response to Andras Zoltan's closing remark: There's also the point made in Tim's answer(+1 there). If he's right, and I think he is, then there's no guarantee that a string is actually immutable after construction, therefore to cache the result would be wrong. Whoa, whoa there! This is an interesting point to make (and yes it's very true), but I really doubt that this was taken into consideration in the implementation of GetHashCode. The statement "therefore to cache the result would be wrong" implies to me that the framework's attitude regarding strings is "Well, they're supposed to be immutable, but really if developers want to get sneaky they're mutable so we'll treat them as such." This is definitely not how the framework views strings. It fully relies on their immutability in so many ways (interning of string literals, assignment of all zero-length strings to string.Empty, etc.) that, basically, if you mutate a string, you're writing code whose behavior is entirely undefined and unpredictable. I guess my point is that for the author(s) of this implementation to worry, "What if this string instance is modified between calls, even though the class as it is publicly exposed is immutable?" would be like for someone planning a casual outdoor BBQ to think to him-/herself, "What if someone brings an atomic bomb to the party?" Look, if someone brings an atom bomb, party's over.

  • jquery accordion - keeps hiding parent element?

    - by PopRocks4344
    Well, I fixed my original question by including after the closing tags, but now, those links won't open? So, basically, in the html below, I'm trying so that only the services section slides open, but I want the h3 tags to open those links... <div id="sp-accordion"> <h3><a href="/?page_id=3">Home</a></h3><div></div> <h3><a href="/?page_id=2">About Us</a></h3><div></div> <h3><a href="#"> Services</a></h3> <div> <p><a href="/?page_id=16">S1</a></p> <p><a href="/?page_id=14">S2</a></p> <p><a href="/?page_id=20">S3</a></p> </div> <h3><a href="/?page_id=9">Contact Us</a></h3><div></div> <h3><a href="/?page_id=5">Tips</a></h3><div></div> <h3><a href="/?page_id=108">Jobs</a></h3><div></div> <h3><a href="/?page_id=131">Newsletter</a></h3><div></div> </div> The accordion works, insomuch that when you click on the h3 tag, the container slides open, however, when it slides open, it hides the h3 before it. So, in the html below, when I click on "Services" the div beneath it slides open, but the About Us h3 disappears... This is the html: <div id="sp-accordion"> <h3><a href="/?page_id=3">Home</a></h3> <h3><a href="/?page_id=2">About Us</a></h3> <h3><a href="#"> Services</a></h3> <div> <p><a href="/?page_id=16">S1</a></p> <p><a href="/?page_id=14">S2</a></p> <p><a href="/?page_id=20">S3</a></p> </div> <h3><a href="/?page_id=9">Contact Us</a></h3> <h3><a href="/?page_id=5">Tips</a></h3> <h3><a href="/?page_id=108">Jobs</a></h3> <h3><a href="/?page_id=131">Newsletter</a></h3> </div> I'm using jquery ui, so the jquery is just this: $(document).ready(function() { $("#sp-accordion").accordion({autoHeight:false}); });
