Not able to access Network Shared Variable when deployed in PC

Initially, when we deploy a Network Published Shared Variable in PC and try to access the same (Read/Write) from RT, we get an error/warning "-1950679023". But when we access the same variable from the PC, it works fine. In the distributed system manager, we can see the variable getting deployed. Also the value changes in Distributed System Manager if we write a value from PC. The attached image "Shared variable Issue.png" will give more understanding of this issue.
The other way round it works fine i.e deploying in RT side and accessing from both RT and PC is working fine.
We also see that the network adapter settings is not loading properly in MAX, if at all we install any software in RT. With no software installed, it loads properly.
The following were the steps that we tried to solve the issue.
1.Flushing the entire NI software and Re- installing again
2.Formatting the RT(PXI).
3.Removing the EtherCAT Card and testing.
4.Checked the network properties of the RT network.
5.Checked the IP/Subnet/Gateway settings.
6.Checked Firewall Settings, If Shared Variable Engine is accessible.

First Root cause needs to be identified before any actions.
I would suggest first check if you can access the shared variable hosted in PC from RT using other ways like using SVE API (Logos and PS protocols, Datasocket etc..)
Check if antivirus or firewall is playing...
Check the same experiment with some other PC if you can.
You can also try creating another Shared Variable in RT and binding the same to the PC and try to access it...
Since you have did all the reinstallations already

Not able to access parent instance variable in outside of methods in child

Hi,
I am not getting why i am not able to access parent class instance variable outside the child class intance methods.
class Parent
     int a;
class Child extends Parent
     a = 1; // Here i am getting a compilation error that Syntax error on token "a", VariableDeclaratorId expected after this token
     void someMethod()
          a = 1; // Here i am not getting any compilation error while accessing parent class variable
}Can any one please let me know exact reason for this and what is the error talks about?
Thanks,
Uday
Edited by: Udaya Shankara Gandhi on Jun 13, 2012 3:30 AM

You can only put assignments or expressions inside methods, constructors or class initializors, or when declaring a variable.
It has nothing to the with Child extending Parent.
class Parent {
    int a = 1;
    { a = 1; }
    public Parent() {
        a = 1;
   public void method() {
       a = 1;
}

Playbook WIFI connected but not able to access network

Hi,
Have a 32GB Playbook and from new has had wifi issues. Running 2.1.0.1314.
Symptoms are that works fine on a variety of open and secure networks until a point where wifi is showing as connected, it tells me I have an internet connection but no apps or browsers able to access the internet, just unable to resolve host name.
Having trawled the internet I have tried the following fixes -
All methods of rebooting and changing date/time etc.
Deleting the saved network - in fact all networks
Changing various settings etc.
The only fix that works is a complete security wipe at which point it works again until the next time, which has now occurred 5 times.
The onset of each episode of being frozen off of networks seems to be login on open connections. I have it set to ask for connection to a saved network and when accepted the login page opens. However on occasion the login "handshake" seems to get confused and I am left with the device supposedly loggedin but no network access.
No matter what I then do the same issue exists on all networks I try until I do a full wipe.
All settings are standard, websites allowed to access location etc.
Can't register the device for support, get the message that support not available.
Any help appreciated.

UPDATE
After deleting all saved networks and rebooting the PB it failed to connect again to the secure network I had last tried.
However, it did connect to an open wifi hotspot. I am wondering whether I need to ensure that the next network I try after experiencing the issue and doing the above is different to the one I was trying to connect to last.
Is there some kind of residual network memory hang up !
Will update again next time it occurs, which historically has been every 2 - 7 days.

Not able to access network shares on a Win 7 Pro SP1 machine on certain machines

I have computer "FileShare"
It runs Windows 7 Pro SP1 and it's current on updates. Password Protected Sharing is OFF, Advanced Sharing is set to "Everyone read/write"
I can access it from other PC's in the same workgroup and no passwords are prompted for. The other PC's run XP or Win 7, and they all work fine.
However I have a Laptop running XP Pro SP3 current on updates, and a Win 7 Pro SP1 TestBox also current on updates.
The Laptop and TestBox require passwords to log into the network shares. I've tried rebooting all of them, adding "guest" to the user list for shares on computer "FileShare", and have even set a blank password to Guest on "FileShare".
Tried Turning Password Protection off and on again. Rebooting again. The Laptop and Textbox still need passwords, while numerous other XP desktops can access the network shares just fine.
Any ideas on what to do?

Hi,
This behavior may occur if all the following conditions are true:
a. NetBIOS over TCP/IP is not turned on (enabled) on one or more computers in the workgroup.
b. The Computer Browser service is not started or is turned off on one or more computers in the workgroup.
This behavior may also occur if File and Print Sharing for Microsoft Networks is not installed or is blocked by Windows Firewall.
Step 1: Enable NetBIOS over TCP/IP
Control Panel > Network and Internet Connections > Network Connections > Right-click Local Area Connection, and then click Properties > Internet Protocol (TCP/IP), and then click Properties.
> click Advanced > Click the WINS tab > Under NetBIOS setting, click Enable NetBIOS over TCP/IP, and then click OK two times > Click Close to close the Local Area Connection Properties dialog box.
> Close the Network Connections window.
Step 2: Start the Computer Browser service
Start > right-click My Computer > Manage > Double-click Services and Applications > Double-click Services > On the right side, right-click Computer Browser, and then click Start.
> Close the Computer Management window.
Step 3: Temporary disable firewall and antivirus programs for test.
It also can be caused by software conflicts. If the issue disappears in the Clean Boot environment, we can use a 50/50 approach to quickly narrow down which entry is causing the issue.
How to perform a clean boot to troubleshoot a problem in Windows 8, Windows 7, or Windows Vista
http://support.microsoft.com/kb/929135
Since the issue does not occur in all computers, you should also compare the different settings between them to narrow down the cause.
Hope it helps.

Network Shared Variable: Aliasing not working

Hello!
I am running a cRIO 9075, which is publishing network shared variables.
I can see and modify them within Distributed System Manager.
Unfortunately I am not able to read/write the variables through labview.
What I have done so far:
Tools -> Shared Variable -> Register Computer, using the IP of the cRIO
Adding a Variable to the project. Type = Network-Published, Enable Aliasing, choosing "Browse" to select the variable (all published variables from cRIO are shown there), Access Type = read/write. The PSP-URL is: \\192.168.10.70\WaveformManager\Op
Trying to read the variable results code -1950679034 and the result is always the default value for that data type.
BUT this works: using the VIs Data Communication / Shared Variable / Read/Write Variable and typing in the same URL the Distributed System Manager is showing is showing (in my case: \\192.168.10.70\WaveformManager\Op)
So, what am I doing wrong? Did I forget something or misunderstand how "Aliasing" works?
Thanks!

hi,
in which way to you read your shared variable? If you read it before you write a value "into" the variable it may couse this waring.
Have you tried this?

http://support.apple.com/kb/ht5209 might help you. An iPhone 4 can airplay content from apps that support airplay and iTunes but it cannot mirror. If your game does not have airplay in the app you cannot mirror it to the apple TV so I don't know if you can play just the music. You should have no problem playing your iTunes over airplay though.

My computer was totally destroyed & I do not have backup or external hard drive with my iTunes library. Will I be able to access my iTunes library when I purchase a new computer? It was the only computer authorized to play library.

My computer was totally destroyed & I do not have backup or external hard drive with my saved iTunes library from it. That was the only computer authorized to play library. I do not have an iPod or iPhone with any of that library (which has over $2K in music purchases & over 5K in songs I ripped). Will I be able to access my iTunes library when I purchase a new computer?

You should be able to access your past iTunes purchases. You'll need to re-rip your CDs See: HT2519 - Downloading past purchases from the App Store, iBookstore, and iTunes Store.

When I added a new contact the screen went black in contacts. I'm not able to access my contacts now. I turned the iPad off and back on, still onlythe black screen appears.

When I added a contact to my contacts, took a picture and added Ringtone, pressed done, the screen went black and I am not able to access contacts. I turned off the ipad but still cannot access contacts.

I don't fully understand what the System Reset does but I've found that it cures many ills. It's easy, quick and harmless:
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears.
A System Reset does not remove any apps, music, movies, etc. nor does it cause any settings to revert back to default.
Also, you might wish to download the iPad-2 User Guide. Pay special attention to page 162. Note that this Guide also applies to the iPad-1 with IOS 4.3 except for those functions that are not supported by the hardware.

Finally, the User Guide can be downloaded at no charge via iBooks and a less comprehensive version of the Guide is included as a Safari bookmark.

WRT51AB - Not able to connect to one site when accessing thro router

When I am trying to access a particluar website directly via cable modem using ethernet cable, I am able to access the website. However if I connect the wireless router to the modem and then try to access the website using wireless connection, I am not able to access the site.
Any ideas?
Any help will be appreciated.
Thanks

Are you able to go online using wireless router?? Logon to router’s setup page and try changing wireless channel to 11, go to advanced wireless settings and reduce beacon interval to 50, reduce fragmentation and RTS threshold to 40 by each, try upgrading latest firmware on the router… also let me know which web sites you are trying to access?? Is it secured websites?

Could not access network location %APPDATA%\ when attempting to install update

Received error message "Could not access network location %APPDATA%\ " when attempting to update itunes and safari on my pc running windows 7 premium home addition. Everything had been working fine. Needed to update becuase Itunes no longer recognized itouch.

With that particular variety of 1606 (it's a 1606 error message even though the 1606 error message number isn't returned by the iTunes installer), the following Microsoft document is worth a try:

Network shared variables lose binding

Hello,
I am developing an application in LabVIEW that uses network shared variables to transmit data between two PC's on the same subnet. The shared variables work fine when running the VI's in development mode, however, when i build the vi's into an executable I find that they no longer work. Here is what I have found so far:
I deploy the shared variable library on the publisher machine (also happens to be the development machine) through an invoke node in the executable. NI distributed system manager confirms that this does deploy and indeed updates as it should.
For the executable on the subscriber PC I created a second shared variable library (same project) with the same shared variables and bound them to the respective shared variables from the first library by selecting enable aliasing, then bind to PSP URL and browsing to the shared variable I wish to bind it to (e.g. \\hallnet-ellm2\shared variable library\serial Number). The machines listed under browse were listed by name so when I tried this initially and it did not work I manually changed the name of my machine in the URL box to the IP address of the publisher hoping that would fix it in case the subscriber could not resolve the publishers machine alias. So now my bind URL read \\192.168.0.1\shared variable library\serial Number.
As part of the executable on the subscriber I deploy this second shared variable library. NI distributed system manager confirms that this deploys but under quality for an individual variable it has a list of issues (see attached) and the bound variable is not updating. At this point the publisher shared variables are still functioning fine. By clicking on 'edit variable' I can see that the variable on the subscriber is still bound but the PSP URL is now \\localhost\shared variable library\serial number. Changing the PSP URL on the subscriber to \\192.168.0.1\shared variable library\serial number enables the variable to update as expected.However by this time my executable has already picked up the error and does not function.
I think that the issue lies with the bind URL used on the subscriber as for some reason it does not keep the binding configured in the project and instead changes to 'localhost'. Why is this? Should it not stay bound to the address specified in the project?
I have tried changing the IP addresses in the aliases file so that
[My Computer]
My Computer=localhost
becomes
[My Computer]
My Computer=ip of local machine
This did not help.
The shared variable libraries are included in the build spec to go into the support files directory and they are successfully deployed from there on both publisher and subscriber.
I am using LabVIEW 8.6 on Windows XP
Thanks for any help you may be able to offer,
Lee

Hi Lee,
I hope you are well. Thank you for your post. Your application sounds very interesting.
Looking at your issue I was wondering, have you tried lowering your firewalls, as this may be causing the problem.
Also, another option would be to setup a private network. Do you have access to any routers that you could use to link the two machines independent of your IT's infrastructure?
The other thing to try is two other computers entirely. Again, it would be ideal to take them off the network you are on, but it's something to try if my prior suggestion doesn't work. It should work on the original two machines though, and it's likely that different computers won't solve your problems because I suspect the network.
Remember that the client variables must know the location of the variables on the server, so you can't move the server exe around without changing this value.
Make sure to set the network location in the "Bind to Source" option for the client variables.
It is also possible to write a separate piece of code to install on every machine that is responsible for deploying the library and by doing so eliminate the need for programmatically deploying the variables in the original application. However, this won't really help you, because the variables you use in the application have to be the same as the ones deployed in the library, so if you change the library, they'll no longer be linked and they won't receive data. You'd have to create a separate exe for every binding source you wanted to link to, and then have a second, known library for the sake of communication locally on the computer between the ‘deployer’ and the actual application. The main application could then be assigned the responsibility of launching the correct ‘deployer’' if it sees it needs to switch to a different variable binding source. This method is not the most streamlined or effective, but it might work.
Just to let you know, you will need to use the DSC toolkit.
Please find below some knowledge base links that I think you will find helpful in your application.
Using Shared Variables in Executables
How do I Programmatically Change the Data Binding Source for Shared Variables?
I hope this information helps and if you can give these suggestions a go and let me know how you get on, that would be great.

Can not edit file on network shared folder after upgrading to windows 7

Merry Christmas and happy new year,
Due to some configuration changes on a specific application, I have forced to upgrade OS of a few number of workstations from Windows XP to windows 7. After upgrading I am facing a strange problem on WIN7 workstations. These workstation are member of a Windows
2008 R2 Active Directory domain which also has a Windows 2003 advanced server additional domain controller. Also there are a number of shared folders on some member servers (all windows 2003) which are mapped as network drives at user logon. Before upgrading
mentioned workstations to WIN7, users was able to edit his/her files on all of mapped network drive according to his/her permissions without any problem on their WINXP workstations, But after installing windows 7 they begin facing problem on one of these mapped
network drives and the problem exactly is when they edit a file, in more specific word an excel file, and then try to save, the excel returns an error message of "document not saved" and exit the excel program. It becomes more strange when you learn
that the edited excel file is disappeared and replace with some "tmp" file. If user copy the excel file to his/her own desktop, edit it and then copy it back to its original place on mapped network drive, it will be replaced normally with its older
version. In other words if user wants to edit an excel file on that specific network drive, he/she must edits it somewhere else and then replace it on the network drive. If the same user uses a WINXP box, there will be no problem.
Can anybody help me to fix the issue?
TIA
Bijan

Thank you Karen,
The problem is fixed, but my case was none of what you suggested. In fact I have
another problem which I described in another question and it was of the root of this excel file issue. I describe what I have done to fix the latter problem hope to help fixing similar issues to mine.
Okay, as it is described in the
question, I was not able to open a shared folder with its UNC address while it could be mapped as a network drive without any problem. I examined what I was replied and some other ways, came to no result. I decided investigate a similar shared folder in
permissions to problematic one to see if the problem is repeated. So I created a folder and shared it with similar permissions and examined it. Surprisingly there was no problem. It was wise to remove sharing of the problematic folder and share it again to
see if the problem resist. But when I tried to remove sharing I received an error message saying that
the shared folder is related to a DFS root. When I took a look at the DFS roots of domain there was no sign of the problematic folder (that made me recall that I created a DFS root with problematic folder mistakenly and removed that DFS root).
After little searching, I found out that the problem could be caused by traces of the removed DFS root. Yep! I found the suspect! The registry key
HKLM\Software\Microsoft\DFS\Domain\problematic shared folder. I removed the key restarted DFS service and log off and on and Bingo!
This problem pops up a few more questions:
1) Why is not the registry key related to removed DFS root deleted from the registry of windows 2003 server?
2) Why was I able to browse this ex-DFS root shared folder without any problem in windows XP while it was problematic in windows 7?
3) As there is no special client service for DFS and user can access DFS root targets like other shared folders what is the deference between shared resource access mechanisms in windows XP and windows 7 that caused the problem?
Bests,
Bijan
