Help ! Connection to RT vi server

Hi !
I'm trying to establish a connection to a PXI 8145RT module running a small vi (Pump Control RT.vi) that control a volumetric pump(LabVIEW 7.1).
The vi works nicely, and can be controled via the "Connect to Remote Panel...) option.
Now, I want to programmatically communicate with this VI, from my PC, to be able to read/write the variables used by the vi.
I wrote a VI (Start Pump.vi) that used to work (2 years ago !) but when trying to connect I get immediately an error 66 : Error 66 occurred at Open Application Reference in Start pump.vi : LabVIEW: the network connection was closed by the peer.
Any suggestion will be welcomed

Thanks for the link !!!

  • Need Help Connecting To My Windows Server Machine From My Linux Machine (What Program To Use)

    My name is Daniel, and I was wondering what program I could use to connect to my Windows Server R2 2012 Computer from my linux laptop. My laptop has the newest version of linux mint mate. I have tried nomachine with no success (but I could have been using
    it wrong I do not really know how). So if anyone could help me out that would be great. Thank You.
    P.S: Sorry for the weird Forum Category there is not really a category for this.

    ok so i think that worked but i ran into another problem; what password should i use? i changed my sql server 2008 username/password and it didn't work. i also tried my windows 7 username/password and it didn't work also.
    EDIT: managed to get it working, all good! thanks a lot.

  • Help connecting Rome with Adobe server

    This question doesn't really have anywhere else to go since Rome is officially retired and has no forum, but how can I get Rome to reconnect with Adobe server so I can access fonts? I've just downloaded the program and right now all I can get are 4 standard ones.
    Thanks for your help!

    As a followup, there was something called “Project ROME” that was never really a commercial product. It was a web application based upon Adobe's AIR runtime system. Further information about it may be found at <http://download.macromedia.com/pub/rome/projectrome_sysreq_faq.pdf> and in fact, you can download the last version of this prerelease product for “free” use as-is - Windows version <http://download.macromedia.com/pub/rome/projectrome_win.air> and Mac version <http://download.macromedia.com/pub/rome/projectrome_mac.air>.
    If you still have documents in this format, I would strongly suggest you save them out to something else before all support disappears.
    In terms of standard fonts, normally such AIR-based software used variants of Myriad Pro and Minion Pro, fonts that are typically supplied with InDesign, Acrobat, Illustrator, etc.

  • Connecting to my local server? Please Help

    Hello,
    I have Wamp setup on my computer to test some database work I
    am doing.
    I have been able to connect to databases on my hosting
    service but need to do some local testing.
    Through many post on WAMP forum I have had no luck in finding
    out why I can not connect to my server though Dreamweaver to my
    database.
    I follow all the instructions I think but I must be missing
    something.
    Config:
    I do have Mcfee (bummer I know) with firewall but it says it
    give full access to WAMP. I have even disabled it and tried.
    I do not have Skype or IIS running or installed.
    I only have apache installed once as far as I can tell.
    I have password and name "root" setup.
    I have databases built in my www folder.
    All services are running in WAMP.
    I try to connect though the normal Dreamweaver way.
    >>Applications >>Databases>>My SQL
    Connection>>
    I input:
    Connection name: DBCart
    MySQL Server: localhost
    Username: root
    Password: mypassword
    Hit the select button and get:
    1)There is no testing server running
    2) The testing server specified for this site does not map to
    http://localhost/wamp/www/dynamicCart/test/_mmServerScripts/MMHTTPDB.php
    URL.
    Verify that the URL Prefix maps to the root of the site.
    I have site set up :
    Local root folder;
    C:\Program_Files\wamp\www\dynamicEcart\Starting_Points\
    Images;
    C:\Program_Files\wamp\www\dynamicEcart\Starting_Points\images\
    HTTP address:
    http://localhost/wamp/www/dynamicEcart/Starting_Points
    ALSO tried leaving this just at local host no luck
    Testing Server;
    Server Model; PHP Mysql
    Access; local
    Testing Server Folder:
    C:\Program_Files\wamp\www\dynamicEcart\Starting_Points\
    URL Prefix;
    http://localhost/wamp/www/dynamicEcart/Starting_Points/
    PHPMyAdmin info:
    User: root
    Host : localhost
    Password :Yes
    Global privileges : ALL PRIVILEGES
    Grant : Yes
    Please please please somebody walk me through this.
    I have been trying for days.
    I need to test my shopping cart.
    I have even tried on my laptop with wamp and Dreamweaver and
    can not connect.
    It must just be something simple I am missing.

    Ah Ha,
    I figured it out.
    I checked the Apache error log and saw that it was looking
    for _mmServerScripts.
    The file for my site was to deep in the www directory (to
    many sub files). I moved it up so that apache could find the
    _mmServerScripts and bingo I am golden.
    I hope this helps anyone who runs into a similar problem.

  • Need free OST viewer tool to help to view OST files without connecting to MS Exchange Server and MS Outlook.

    Need free OST viewer tool to help to view OST files without connecting to MS Exchange Server and MS Outlook.

    Hi Howard,
    As I know, Microsoft does not provide any kind of inbuilt tool or free software to only view OST file, even without the connectivity with exchange server (Offline).
    Try SysTools OST Viewer freeware which helps you to view all OST file save at your system in an easy way, whether you want to see the attachments or other items of OST file.
    Note: This is a free inbuilt utility, but try it on your own risk as I am not much aware about it and its working. But this tool sounds good according to your requirement and hopefully it would give you 100% satisfaction.
    Thanks

  • Please Help.  How can you monitor a directory using jndi connection to a ldap server?

    How can you monitor a directory using jndi connection to a ldap server? I
    want the ldap server to monitor the content change in a file system
    directory on another computer on the network. Can someone please help.
    Thanks
    Fred

    Hi,
    Why do you want to use LDAP for Hard disk monitoring..???
    U can do this by creating a MD5 checksum for all the files existing in some
    perticular
    directory and every hour or any configurable period u can recalculate the
    checksum
    to find out the change in the content.
    I guess all u need is to get the code for "updatedb" utility of Linux and
    instrument it for ur needs..
    Hope it helps...

  • DB connection pooling to remote server, pls help!

    Hi guys,
    I really need help with this and I am not exactly the most experienced developer.
    I have a java application which connects to a remote MS SQL server using the connection pooling object model described in Sun docs at:
    http://java.sun.com/developer/onlineTraining/Programming/JDCBook/conpool.html
    I am Using the 'sun.jdbc.odbc.JdbcOdbcDriver' driver.
    In the client class (DAO) in a      static {  try{} } block I create the JDCConnectionDriver and JDCConnectionPool. Then in the constructor of this class I instantiate the connection object, which I use through out the class.
    This class is instantiated multiple times in the lifetime of the application( thus the static block for the connection pool).
    It all works great if the SQL server is on the same machine. But as soon as I change the ODBC connection to a remote server, my application does not seem to release the connections. After several hundred instantiations of the client DAO class there are so many ports taken (live connections) on my server that it affects other applications.
    Does the garbage collector fail or does it fail when it works with the MS ODBC driver with remote connection?
    I debuged and debuged both with local sql and remote -- the workflow seems the same.
    Has anybody out there faced the same problem? What am I doing wrong? How can I resolve this?
    You help is greatly appriciated!
    Stan

    I am using the datasource very heavely, but I am sure
    the closing/releasing is ok. If the sql server is on
    the same machine, it all works flawlessly. Only when
    sql is remote I see unclosed connections, which pile
    up as I am creating more and more.
    Any suggestion?Your description seems to indicate that you are not actually closing the connections by calling the close() method. Make sure that you close the connection when the task at hand is finished. Closing only makes the connection in the pool available again.
    Also, if you are using datasource heavily, you should be attempting to minimize the lookups. JNDI lookups are relatively slow.

  • Sync failure because itunes cannot connect to the sync server PLEASE HELP!!

    HELP! I cannot get my info back into my iphone.
    During sync I get an error message that says 'sync failure because itunes cannot connect to the sync server''
    I have had this problem today so i restored the iphone and it has synched the ipod portion but will not sync calenders, contacts , email accounts or bookmarks.
    The restore erased all of these and now i cannot replace them.
    Thank you in advance for any help in solving this crisis.

    I had the same problem (not from day one but within the past couple months). Anyway, I wish I had made note of everything that the quick-and wonderful-Apple support did when I finally decided to give them a call today-after getting tired of not being able to update calendars and contacts and not seeing any helpful info here-unfortunately, I continue that legacy (as I can't remember everything I had to do to fix-sorry) Ultimately involves creating a new user I called mine IPHONE...then doing some of this and that-and finally merging info and going to "Terminal" and typing in some code...then deleting some of the old files, Took about twenty-minutes on the phone. Sorry I didn't think ahead for others and write al this down...but just know the Apple people were great. I talked to a gal for about ten minutes very methodically trouble-shooting. When nothing worked she shifted me over to a real nice guy who calmly and politely guided me through all the steps to fix this annoying problem. I hate to say it, but just get on the phone and-if you have the same experience as me-you will get 5 Star treatment and your sync will work like a dream. Every time I have to contact Apple Support (which isn't that often) my experience is nothing but the best. Unbelievable customer service! Methodical, Personable, and truly knowledgeable! There is a fix and it works like a dream. Not that hard but you'll need customer service to walk you through it-as I can't (sorry I can't be of much help...) Good luck!

  • Help (pleeeease) with configuring FTP server connection

    HI...I am so frustrated. You have to understand that I am not completely stupid, but I just cannot understand the process which will allow me to connect to a **^&-**** FTP server!!!
    Here's the deal:
    Me, graphic designer, designing among other things, websites.
    Dreamweaver, the software program that I use to design websites.
    So, I design a site, and configure it to upload via FTP. I get the FTP hostname, username, password info from the intended Internet Service Provider, and load that info into the required fields in the Site Manager window. Everything is great until I try to connect to the server....it just won't do it! I get error messages that state flatly that I cannot connect to the remote server, for reasons that are as bland as "username and password information incorrect". I have called the ISP to determine if I am using the correct username, password blah blah blah, and everything checks out on their end. It seems that everyone else but me can connect to a bloody FTP server! Harrumph.
    So...what can I do? Is it that something in the System Preferences panel needs to be adjusted to allow me access to FTP? I have fiddled around a little in there, but don't change anything, because I don't know what TCP/IP, proxy settings, etc. MEANS!!! All I did was allow FTP access (duh).
    Another point of interest is permissions...somewhere along the way, during my long and convoluted journey with this problem, a message came up that mentioned that. Permissions. Don't know what that means either.
    Is there anyone out there that can help me?? I am so confused, and just need a little education. I would greatly appreciate any advice or information. Thanks! Janelle
    iMacG4   Mac OS X (10.4.7)  

    Hi Janelle: I assume the domain is georgeponzini.com
    1. http://georgeponzini.com/index.htm works so we know you have an index.htm page uploaded to the server but it contains no information at all, like you uploaded a completely blank page, no title, no code, nothing, nada...
    2. http://georgeponzini.com/index.html does not exist, you never uploaded a page so what we see is an error page, saying such a file does not exist.
    3. The link you have ftp-dom.earthlink.net/ is for uploading directly from a browser but I could not get it to work in Safari but does work in Firefox, which you can consider downloading and using.
    4. If you can upload from your Control Center at Earthlink.net, that's a no brainer, this is the option to take, you cannot make any errors doing it this way. But that we'll figure out next... It's ok you do not see a public_html folder you are probably already in it when you log in. Where you given instructions to upload into the WEBDOCS/ folder, if so you did that right.
    BTW - have you checked with Earthlink that Control Center will work on a Mac using Safari asa browser
    5. Your index.htm page/file is NOT where you upload to, the index.htm IS the 'Home Page' or 'Index Page'. You're seeing a white page because it contains no information, but you must have uploaded a file/page named index.htm (see 1 above)
    6. If you have files/pages uploaded in the correct area, see if you can rename any file index.html - I am sure you can do this at the Control Center, if not do this on your computer and use 'save as' > index.html - upload this file/page and see if it displays
    Let me know what happens, Rick
