Datasocket VI at client side just stops

Hi guys, I am trying to send microphone-captured sound to another PC (both PCs connected by cross-over cable). I tried various options like TCP, Datasocket but none worked. With TCP it always shows input buffer overflow. With Datasocket, it doesn't show any error but the VI on the remote PC just stops. I have not been able to figure out the problem. I am using LabVIEW 2009 version 9. I am attaching the two VIs for your testing. Please help. Thanks. Regards.
Solved!

Hi Rocky,
I looked at your code, and made a few changes. First, I couldn't tell why you were dividing the samples/ch by two for the read sound function. I disabled that. Also, the "Initial Data" you were feeding to the first "sound write" VI and at the default data input of the DataSocket Read function was a waveform cluster. The sound data sent over the DataSocket connection is an array of waveform clusters (one cluster per channel). This probably was causing DataSocket problems for ya.
I set the sound configuration values to what I found in the "Continuous Sound Input.vi" example VI. I also added a few charts for visual indications.
Note that you must have DataSocket Server running (on windows: Start->Programs->National Instruments->DataSocket->DataSocket Server).
If these don't work, I'd look at network/firewall issues. Also, if you want less latency, consider using straight-up UDP. It should have less overhead than DataSocket (and with a crossover connection, I'd guess you won't have much data loss to worry about).

    Try closing the Camera/Skype app:
    1. Double-click the Home button to reveal the Task Bar
    2. Hold down the Camera/Skype app for a second or two until you see the minus sign
    3. Tap the minus sign to close app
    4. Tap area above Task Bar to return to Home screen
    If the above doesn't solve the problem, do a reset:
    Hold the Sleep and Home button down for about 10 seconds until you see the Apple logo. Ignore the red slider

    Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
    When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
    If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
    If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

  • How to generate rule log on client side

    I am looking for a solution where I could generate a rule log and make it available on client side. I know generating a log during consolidation and save it on server. However, I want to make it available on client side.
    I have created four scenarios in HFM application, namely -
    1. ACTUAL_REPORTING - To capture TB data and use it for reporting
    2. ACTUAL_ICP - To capture ICP data and run custom business rule as per requirement
    3. ACTUAL_ADDINPUT - To capture additional memorandum inputs
    During consolidation,data is copied from ACTUAL_ICP and ACTUAL_ADDINPUT to ACTUAL_REPORTING. However, problem is that user should consolidate ACTUAL_ICP AND ACTUAL_ADDINPUT scenarios first. If they miss executing the consolidation in these scenarios, then the data copied would be wrong. Just as to ensure this, there's a provision is HFM to check calculation status in rule file and looking at that, calcuation could be stopped and a message could be sent to the user. But delimma is, how to report the same on the user side.
    Possible solution that I could have thought are -
    1. To generate a rule log and post the same to the client, but how to do this? As path of the rule log could be of the server only (that is C:\Hyperion\Logs\Rule)
    2. To generate a rule log and pop a web page terminating consolidation, but how to do this?
    3. To raise an error from the rule file and direct it to the system messages, but how to to this?
    Please advice and any further clarification is required please contact me.
    Thanks & Regards,
    Mustafa

    You can define the output folder as a share, which has already been mentioned. I strongly advise against implementing any solution that in production will regularly generate an external file.
    1) The output file is generated by the DCOM user. If you want this user to generate a file in a specific location, it must be writeable by the DCOM user, and readable by the intended human user. Make sure both NTFS and share level permissions on the target file and its containing folder consider this. Latency for the file write can degrade performance.
    2) Most HFM implementations have two or more HFM application servers. You have no control over which server will execute the file, and also no control over what happens if two or more servers try to write to the same file. You can create a process which causes HFM to become single threaded if every time Sub Calculate for any entity on any server needs to open a single file. This is because the file object is single threaded. It could be multi-threaded if you write out to a database, but certainly far more complex.
    3) Wait state: while as in #2, this can single thread the process, and you have to consider whether your process will error out during moments when another process has access to the file, or if you will ignore that and simply proceed. This can have a significant impact on performance time if you decide to wait until the file becomes available.
    While I have done implementations where the overall solution required combining data across multiple scenarios, I consistently find this a cumbersome, error-prone, and poorly performing approach. For this reason, I always try to keep all of the data required in a single scenario. This is one key reason why the "DataSource" or "DataType" (or whatever you call it) approach is so popular and successful.
    Finally, you cannot write to the HFM system messages. You can, on the other hand, use Calc Manager to write out to a system log.

  • Client Side Rendering on Terminal Servers

    I’m having horrible printer issues on my Terminal Servers such as slow printing, slow to add printers, some applications load slowly because they are enumerating the list of printer (thanks Procmon), slow logons, etc. I'm trying to get Client Side Rendering
    (CSR) disabled. From what I can tell it still appears to be on. Terminal Server are Windows Server 2008 SP2 x86.
    On my print servers I have verified that all printers have Render print jobs on client computer unchecked. I have a Group Policy linked to the OU that the Terminal Servers are in that has
    Always render print jobs on the server set to enabled. Per
    http://blogs.technet.com/b/askperf/archive/2008/02/10/ws2008-client-side-rendering.aspx I have verified that on each Terminal Server in
    HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Printers the
    ForceCSREMFDespooling value is present & set to 1 so the GP is being applied.
    However I still have tons of entries in HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers\Client Side Rendering Print Provider\Servers\<SERVERNAME>\Printers.
    I have found KB958656 which seems to describe my problem that CSR is not being disabled. However one of the files it updates is older than a file that I have (win32spl.dll) & one is newer (printcom.dll).
    Printcom.dll in hotfix is 6.0.6001.22288 mine is 6.0.6001.18000
    Win32spl.dll in hotfix is 6.0.6001.22288 mine is 6.0.6002.18005
    Has anyone else seen this behavior & been able to get CSR disabled?
    Has anyone else had success with the KB hotfix mentioned or know whether or not installing it would causing any issues (since it has that older file)?
    Thanks in an advance to any input.

    Alan/Patrick,
    Hi, sorry, went away on leave for a while so didn’t respond.
    Alan – our case was REG:112081612189183.
    For someone who has been dealing with MS support for about 20 years, this was the most disappointing of any support call I’ve ever had raised – to have the call shut
    down, without a perfmon trace, process explorer analysis, or hang dump analysis (of spooler) – and simply blame “3<sup>rd</sup> party drivers” without any proof – is utterly deplorable.
    Anyway, for anyone’s benefit who has similar problems – trying to do direct printing from RDS – I’ve managed to get a solution working. 
    Here are the details;
    A nightly print spooler clean-up script that;
    Stops the spooler
    Deletes the entire key under “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers\Client Side Rendering Print Provider”
    Re-creates the key (empty) and sets the value "RemovePrintersAtLogoff"=dword:00000000
    Note, this was vital. 
    MS support had recommended we set this to 1, along with some other keys (InactiveGuidPrinterAge, 
    InactiveGuidPrinterTrim) with specific values.  If we used these MS support recommended values, our RDS serer would not enumerate printers for more than 3-4 hours before requiring a restart of the spooler.
    Restart the spooler
    Map a printer (just to make sure it works)
    Clean up the USERS\.DEFAULT\Printers key on all existing servers
    There was heaps of crap here, the default user NTUSER.DAT was over 800MB in size
    Modify the security on the registry, using GPO to deny SYSTEM write access as below, to stop the crap writing here again;
    USERS\.DEFAULT\Printers
    Deny Set value
    Deny Create Subkey
    Run NGREGOPT on all servers to compress the DEFAULT and SOFTWARE hives back down.
    Even though we had deleted the crap from “Client Side Rendering Print Provider” and the DEFAULT user hive, the registry files were still large of course, and needed to be compressed to reduce
    paged pool usage.
    Note, make sure no users are on the server when this is run !
    With the nightly spooler ‘refresh’ and the registry security changes, we are no longer seeing any problems. 
    In addition the paged pool has gone down from 5GB to 1GB – which I believe was related to the registry bloat that had occurred previously. 
    Cleaning up the keys and using NGREGOPT has fixed this.
    In addition, I am running a spooler check script every 30 minutes on each of the 13 servers. 
    This script checks how long it takes to enumerate the printers for the specific test user. 
    If it takes more than 20 seconds, we get an alert.
    Since I have made the changes above, we no longer have any printing problems… touch wood.. even using HPD 5.4 for most printers, and other (RICHO) 3<sup>rd</sup> party
    drivers.
    If anyone wants the scripts (the spooler refresh or the check script) let me know on david.frith<at>glfconsulting.com.au

  • Password hashing on client side

    Hi. I would like my users to have their passwords hashed in SHA1 at the client side when they login so that when the html form comes to the server, the password is hashed and in case if the form is being eavesdropped on , I do not need to worry about the passwords in plain since it's hashed.
    I am not using SSL because there isn't much things to encrypt or hide secret other than just for the login passwords or users changing their user profile like updating their passwords. And SSL can add quite abit of cost to my client's web hosting budget.
    So simply, is there anyway to hash passwords in client side using JSP before it is sent to the server ?

    Not using jsp no, because JSP stands for Java SERVER Pages. Meaning that java/jsp only runs on the server.
    You can do it in javascript client-side: http://www.movable-type.co.uk/scripts/sha1.html
    But whats the point?
    Now instead of sending what they user typed in, you send the hash of it.
    If anyone is monitoring the line, they can just send the hash of it as well.
    No protection is afforded you by doing this.
    Hashing the password doesn't stop someone stealing it by tapping into the line.
    What is DOES stop is somebody querying your database and saying "give me a list of username/passwords"

  • DataInputStream with slow client side connection

    I need to stream some data to client. server pushes all messages once connection is established over internet.
    but when internet connection is slow (like wireless). i see lot more messages in receive Queue on client side. then for a brief period of time, server stops sending messages (may be due to socket channel is full or something)
    so it looks like application is stealth mode. then all of sudden application starts consuming messages (may be when that channel gets empty)
    any idea how to fix this slow connection issue? i don't care if client drops certain messages. how can i flush or empty out that socket channel ?
    below is the code snippet that i am using...
    try {
           InputStream is = new URL(streamerUrl).openStream();
           ds = new DataInputStream(new BufferedInputStream(is));
           parseBody(ds);
        } catch (IOException ex) {
                        logger.error(ex.getMessage());
        }

    My decision was to send acknowledge and if server side can't get to acknowledge it will skip all new messages.If the server can't get an acknowledgment it can only mean that the connection has failed, which will manifest itself to the server as an IOException: 'connection reset' on a write. The acknowledgement adds nothing except latency and more bandwidth usage.
    So why not skip message while network lacking.I agree, but why not use what the network is already telling you, rather than adding more messages and more failure modes? Now it's the client that has to look out for connection resets. You've just moved the problem.

  • How to Print Crystal Report without any dialog message on the client side

    Hi!
    I've read too much questions like this, but i can't find any answer.
    How can i print a report on the client side directly?
    I have three buttons, "Generate Report", "Generate PDF", "Print".
    I want when the "Print" button was clicked, automaticaly the report is printed using default printer, like PrintToPrinter function, but in the client side.
    Thanks!

    If you search for previous posts about this, you will see many posts saying not possible.  If this functionality was possible, you could essentially have a page that would send something to a clients printer just by visiting the page, how bad of security hole would that be?

  • How to use KeyChain API from client-side HTML scripting in Safari on iPad?

    I have a requirement where I need to add client-side scripting in an HTML page to be supported by Safari on iPad that creates a private / public key pair and that creates a CSR (Certificate Signing Request) in PKCS#10 or SPKAC format that can be sent to a certification authority server using form HTTP/POST that will then return the generated certificate.
    I initially thought that I could simply use the HTML 5 tag <keygen> which can do exactly what I need, but unfortunately this tag is not at all supported on mobile Apple devices like iPad or iPhone, so I have to look for another solution.
    I have noticed that the KeyChain tool should be available on iPad using the documented API, but I have no idea based on the documentation whether the API can be called from client-side HTML scripting on iPad.
    Question : is it technically possible using the functionalities and API's exposed on an iPad to implement what I just described in HTML client-side scripting? If so, do you have some links with useful information that can help me on my way?

  • How To Update A Table View From Client Side !!!!

    Hi I would like to update a table view from the Client Side. So that the user can keep updating the relevent data on the client and when they have finally finished they can press Save so the entire page is then sent to the Server.
    Does anyone know how to do this, I guess u have to use the EPCM, I have just started on it and would really appreciate some Help.
    Thanks,
    Emmanuel.

    This is what I found :-
    There are a couple of ways to approach this.
    1) load the excel spreadsheet into the database "as is". You can use interMedia
    text to convert the .xls file into a .htm file (HTML) or use iFS (see
    http://technet.oracle.com/
    for
    more info on that) to parse it as well. InterMedia text will convert your XLS
    spreadsheet into a big HTML table (easy to parse out what you need at that
    point)
    2) Using OLE automation, a program you write can interact with Excel, request
    data from a spreadsheet, and insert it. Oracle Forms is capable of doing this
    for example as is other languages environments. In this fashion, you can remove
    the "manual" and "sqlldr" parts -- your program can automatically insert the
    data.
    3) You can write a VB script that uses ODBC or Oracle Objects for OLE (OO4O) in
    Excel. This VB script would be able to put selected data from the spreadsheet
    into the database. We would recommend OO4O. It provides an In-Process COM
    Automation Server that provides a set of COM Automation interfaces/objects for
    connecting to Oracle database servers, executing queries and managing the
    results. OO4O is available from
    http://technet.oracle.com

  • My iphone 4 just stopped receiving or making calls.  I have tried everything! Help!!!

    Okay, one day a little less than a MONTH ago, my iphone 4 just stopped receiving calls(90% of the time) and making calls(50% of the time.).  I panicked because my job depends on my phone to work.  So, i go to apple, ATT, back to apple, back to ATT, etc.  There is no end to this.  And, literally, the people at ATT and Apple, keep telling me that they are probably not going to figure out a solution, and that I should just cancel my account.  Now, I really don't want to do this!!!!!!!!!!!!!!!!!New iphone from apple because they thought it was a ATT problem but gave me new iphone 4 anyway, new sim about 1 minute after the new phone, new phone number. The engineers at ATT said if i relocated and told them that i was moving, it would give me a new number and reset all the routing stuff.  I didn't want to do this because of losing my number with business, but had to resort to it anyway.  Now I have a number from a different state, and I still have the problem!!!!!!!!! I have exhausted all my options with apple and att, and both tell me the only thing i can do is buy a prepaid phone from a different service!  I need my iphone for work, and this has been going on for over a month now.  I was told there was a routing issue, but the engineers opened a ticket on it, and NO solution.  Then they opened a second case ticket, and still no good.  They are claiming I should cancel and buy a new phone.  My phone just stopped recieving calls one day.  No notification of missed calls, EVER since this started happening.  Voicemails go thru( only some of them) about an hour or two later, and texts are taking a bit longer than usual.  I have really tried everything the engineers can think of, even getting a brand new phone!  Please someone help me!!!!!!!! I am desperate!!!!!!!!!!!!  This happens anywhere i go, not just in my area.

    Might sound silly but is the mute switch on the left side of the phone in the correct position?

    The reason I asked about the computer OS was in case you needed to do a clean install of iTunes. It works differently on the Mac computer than on Windows. A complete uninstall and reinstall on a Windows computer requires you to follow specific instructions in a support document, while on a Mac, I have read you just have to reinstall over the old one.
    I'm not sure if installing/updating to iTunes 11 would be the same on Windows or not, but since you report using a Mac, then it is probably a mute point. Good luck.

  • Why does IE8 running on XP and Win7 Virtual Machine deletes the history while I'm still browsing the same site with client-side hashbang routing?

    Hello, 
    I have a asp.net mvc 5 web application running on .net 4.5 hosted on my local windows 8 machine on macbook pro using parallels. I'm running Internet Explorer 8 Version: 8.0.6001.18702 running on XP and Version: 8.0.7601.17514 running on Windows 7 Enterprise.
     I've got both of the virtual machine source from www.modern.ie 
    My web application is attempting to provide single page user experience by having some client-side routing by using '#!/xxx' hashbangs in the url so that I can get and post via ajax and change the hash in  the url without causing the page to reload. My
    code works fine in IE9+ and other modern browsers.
    However, I'm facing this strange issue in both of the IE8 versions. When running my demo app in IE8, I can login, view home page and can navigate from this home page to many details page. From the very first login page, all the pages are the result
    of form's post action via ajax which then expects html from server and loads in the DOM. The page structure of my app is like summary form => Details page (can also contain summary forms) => Details...so on.
    The above process works fine for few of the navigation steps. If I keep navigating from one page to another & go back, I have observed that the browser back button is removing the history items slowly. And a time comes when it totally forgets about
    all the history pages that I visited to reach this current page I'm viewing!! It treats like I have just started my browsing session and this current page is the first page I've landed on with no back option. Now if I again try to navigate, I have encountered
    problems like both the back and forward buttons gets disabled.
    Hope, my words above is clear enough to explain this problem. The same application works fine in IE9+ and other browsers. 
    Till now, I have tried following steps on both VMs: 
    Resetting IE8.
    Increasing disk space to 1024mb for temporary internet files storage.
    Setting 'Never' for Check for newer versions of stored pages.
    Disabling the automatic crash recovery feature didn't helped in this case. Found this on support website.
    Deleted temporary files, history, cache, etc many a times.
    Search many forums, posted question on StackOverflow, ASP.NET
    Forums - but didn't helped.
    Tried 'beforeunload' event of browser to see if any of the page is reloading because of submit or any other reason. But the page doesn't reload at all.
    The issue is browser forgets about the browsing history while I'm still browsing the same site. 
    Is there any possible fix for the issue above? Does IE8 have any issues as many ajax form post is happening on every page? 

    I have really tried many things to identify any possible reason of the issue above. Even rewrote all my javascript navigation code and checked server-side code.
    But the only place where I got the solution is at site: http://www.enhanceie.com/ie/bugs.asp which states that there is a bug in IE8 which reads like:
     IE0012: IE Travellog broken when navigating back/away from a page with
     a large POST form If there is a form input field with a value longer
     than 523,659 characters, when you navigate away from the page, IE may
     clear the current session's travellog (similar to history), disabling
     the back and forward buttons. Repros in IE6 & IE7.
    There are following solutions that you can go for:
    - Check for the input field that has lots of characters as mentioned above and solve your problem.
    - If you have control over the system where IE8 will be used, you can add the following registry key on that machine. There is no existing key, so, you need to add a new one:
    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\TravelLog] "MaxSize"=dword:ffffffff
    I am really relaxed to find this information as I spent really long time to solve this issue. Hope this will help someone.

  • The Group Policy client-side extension Scripts failed ...

    This is an error I've been seeing forever and it was always the impression that upgrading would resolve it, but it never has even in 10.3. 100% of our users get these errors in the Event Viewer:
    Event Type: Error
    Event Source: Userenv
    Event Category: None
    Event ID: 1085
    Date: 10/21/2010
    Time: 8:04:52 AM
    User: NT AUTHORITY\SYSTEM
    Computer: XXXXXX
    Description:
    The Group Policy client-side extension Scripts failed to execute. Please look for any errors reported earlier by that extension.
    For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
    We also seem to have flakey policy issues where once in awhile a user will not be able to logon to Windows with Workstation Only while getting the " not allowed to logon interactively" message, other times the users report not being able to access the Windows Date and Time Properties and further sometimes they are unable to make system changes.
    We have troubleshooted this and the only resolutions we've found are to run zac cc, zac ref, zac pl and sometimes it seems like deleting c:\windows\system32\grouppolicy will help.
    In regards to the Event Viewer entry I posted, on any given machine I can issue the command gpupdate and it will put another entry into the Event Viewer (sometimes multiple ones). I've learned through research that if I "clean up" c:\windows\system32\grouppolicy\gpt.ini the errors go away, but once the policy is refreshed they come right back.
    This is the version ZenWorks gives the users:

    This is the version I cleaned up:

    I'm not sure how to get Zenworks to use the cleaned up version nor and I too sure what those extra extensions are and how they got in there. I may need to contact Novell in regards to this, but since I'm already working on an SR with them I figured I'd go ahead and post here first.
    Any help or advice would be greatly appreciated.

    Here are the groups I'm using. NOTE: These have been in affect throughout the issues experienced. Users will work perfectly fine then suddenly the problem will start happening without any policy change on our side.
    -Member of-
    Network Configuration Operators+
    Remote Desktop Users+
    Users+
    -Assigned Rights under a group I called "Other Rights"-
    Access this computer from network
    Change the system time
    Log on locally
    Shut down the system
    The only condition I have is that these issues happen when logging in Workstation Only and I'm not able to recreate the problem on demand with tests.

    When user's get this error, it generally means their account is not in a
    local group that has been assigned that right.
    If using "DLU", make sure the user accounts are a member of "Users".
    And If anyone was messing with security policies, make sure they did not
    take away "Interactive Logons" from anyone.
