Problem running duplicate SubVIs

I have a SubVI that I want the user to be able to launch (up to) 4 separate instances of. It's a small grouping of indicators that represent possible error conditions for 4 separate but identical sections of the hardware being monitored.
To accomplish this, I set up the following code:
I need the indicators that are in the SubVI to be updated even when the user isn't looking at them (because there is separate history tracking going on), so as you can see above, I make 4 (nearly) identical calls to run the VI, then in an event structure, when the user clicks on the control associated with each section, it executes the FP.Open command for that particular VI's reference.
When I executed this, the only one that will open is the first one (vertically), the one that's set to the base address of 10000. I presume this is because it's the fist reference that runs when the main program executes.
So then I went and edited the properties for the SubVI to set its reentrant execution to "preallocated clone reentrant execution", but this made no difference.
Any thoughts on how to solve this problem? thanks in advance

I thought I was pretty clear by calling the function the Open VI Reference. That is its name after all.
Here's what I am suggesting.

Dataflow problem, queuing in subvi dequeuing in main vi

ive stuck on a very simple data flow problem here, I'd like to pass data being enqueue in the subvi and dequeue in the main vi consumer loop. Ive attached the vi, since im already stuck on this problem, i was hoping i could learn a few things, specially implementing action engine in this situation
thanks.
Solved!

Your subVI doesn't make any sense since your loop will always exit after the first iteration and you always initialize your counter to 0 every time you execute it. That is one issue.
Your code also suffers from multiple places that are dequeueing data from the queue. You will get undeterministic behavior since you don't know which dequeue will get the data first. Generally for a producer/consumer architecture using queues one or more loops loops should be enqueueing data to the queue. One and only one loop should be dequeueing data. These loops shuold run in parallel to each other. In your code you will only run your subVI whenever you press the start button and as stated you will always post a value of 1 to the queue. What you would need to do is have your subVI run independently once it is started. Use the "Start Asychronous CAll" to start your subVI when the Start button is presed and then let it simply run. Have it post the counter to the queue. Your lower loop in the main VI should dequeue the values and display them. You do not need the Wait in that lower loop since that is the purpose of the dequeue. That loop will be idle if there is no data present and will only run when data is in the queue.
In the upper loop of your main VI remove the dequeue and enqueue. You don't need them since the subVI is all that is needed to post the data to the queue.

Run a subvi by pressing a button multiple times

Hi
I wanted to run a subvi each time the user pushes a button.
So the subvi might be called multiple times & different instances of the subvi run simultanously with their front panels open.
To do this I made a .vit & call it by refrence wehenever a button is pressed but it doesn't work.For the first time it opens but it seems as if the .vit doesn't return after it is called. while if I use the same method & call the .vit by reference 2 times in parallel both of the front panels open without problem.
How can I solve this problem(the main & the subvi are attached LV 7.0).
Thanks for your attention in advance

Hi,
You have to run it dynamically, with the Run VI method. This method can
optionally wait or not. Before running the VI, you have to set the controls
with the method Set Control Value (or Set Control Value [Variant]).
There are several ways to read back values from dynamically started VI's.
One is to use a buffer (lv2 global). Another is to use the Get Control Value
method.
It's complicated, but if you put all this code in a sub vi, you'll end up
with a nice main...

Wiebe.

Problem Running SSIS Package with a SQL Server Agent

SQL Server: SQL Server 2012
VS: Visual Studio 2012
Hello,
      I have been having a problem running SSIS packages by using a SQL Server Agent job. I first created these SSIS packages in a separate IS project in Visual Studio. I imported the packages to the Integration Services (Package
Store) instance on my SQL Server and tried to create a job that would run them from there.
      At first I read around about needing a proxy account to allow the agent/packages to access the file system since these packages are importing data from a flat file in the SQL database. So I created a temporary admin user to
use as the user for the agent. I did this by going to Services.msc on the server and linked the account the agent's "logon as". Then arose another issue where I am getting an error about using the incorrect type for my connection managers.
The connection manager "TestFile" is an incorrect type. The type required is "OLEDB". The type available to the component is "FLATFILE". Source: Data Flow Task Flat File Destination [2]     Description:
Cannot open the datafile "O:\*****\Success.txt"
I am not sure what this even means as I am getting this error even with a test package that doesn't do anything with the database. I have just two flat file connection managers in this test project one for grabbing the source file and one for
creating the new test file.
I am not sure what to do.
Thanks in advance,
Matt

im trying to download itunes 10.5 but keep getting error message that says: There is a problem with this Windows Installer package. A problem run as part of the setup did not finish as expected. Contact your support personnel or package vendor. I am using windows XP 32 bit, all the other computers in my house downloaded just fine, no problems, however this is the computer my iphone is set up to, ive tried doing a virus scan, windows update, downloading other things, updating everything possible, everything works fine, its just itunes that wont download, anyone have any other ideas?

Yes, I had found a similar solution also. I'm running XP Pro, SP3. I went Control Panels/ Add-Remove programmes/apple software update/ change/ repair. Then run the 10.5 exe.
While the programme updated from version 8 of iTunes, my new iTunes is now a mess. Not all of my music was in the same folder previously but it all showed up on iTunes. Now many albums have been left out, some have only a few tracks and some have two copies of some tracks as well as having other tracks missing. I haven't begun to work on that.

Problem running BI template installer after upgrade to 2004s

Hello,
After upgrading our Portal from EP6 to EP7 I have a problem running the BI template installer. The failure occures right at the beginning. The installer is looking for SLD related parameters in the 'CTC> Propertysheet SystemProperties'.
But there are only three parameters in the sheet :
HOST, SYSTEM_ID, INSTANCE_ID.
If you instal a new 2004s system you see much more entries in the 'Propertysheet SystemProperties'.
My question is how to add these missing entries into the 'Propertysheet SystemProperties'.
Thanks
Boaz

Hi Kaylan,
Actually there are only two things to manually fix after the CTC template run, which is mentioned in the Blog:
- check/correct the following settings in the NetWeaver Administrator for evaluate_assertion_ticket and ticket according SAP Note 945055
- the entry in table RSPOR_T_PORTAL for Platform and PDF fonts
If you uncertain, you can remove the created objects as stated in the Document http://scn.sap.com/docs/DOC-11607 => Page18 in the Notes Section. the CTC template is creating these objects and entries again.
Best Regards Roland

Having problem running an application

I have recently installed jdk 1.2.2 and i have no problem running applet but when i try to run an application i get the message 1 error can't find<filename> . java.
The path in autoexec.bat is fine. JRE File is include in my file jdk1.2.2.
I have installed and deinstalled it a couple of time and can't make it work.
Could someone help me please!!
Thanking you in advance!

doesn't sound like a path problem at all. you say when you try to RUN the app you get a message can't find filename.java. When you're running the app you run the binary class file i.e. java MainClass.class. If you're compiling the app you would do javac MainClass.java. Clarify your situation further if this does not help you out.

Problem running Lex in project created with Forte C++

I am having a problem running Lex in project using Forte C++ 6. I believe I may have an installation problem, but can't figure out where it is.
I created the project using Workshop. The make file generated is trying to run the following command: lex -o output/cmdscan.o cmsscan.l
Which causes the following error message lex: illegal option -- o
I checked the man pages and Lex doesn't have a -o option.
Is there another version of Lex installed by Forte C++ that is different than Lex from Solaris?

Problems running Flash Builder 4.6 profiler

Hello,
I have a problem running Flash Builder profiler. When I click "Profile" it starts my web application, but nothing else happens inside Flash Builder itself - no new data appears in Profiler perspective, Flash Builder itself doesn't show any sign of doing something.
My mm.cfg contains the next line: "PreloadSwf=C:/flash builder workspace/.metadata/.plugins/com.adobe.flash.profiler/11/ProfilerAgent.swf?host=localhost &port=9999"
Additional details:
OS: Windows 7
Flash Builder version: 4.6
Tested web browsers: Firefox, IE 8 - the same problem in both of them
Flash player versions: ActiveX/Plug-in Version:11.7.700.169
I made sure that ProfilerAgent.swf indeed exists in the location defined in mm.cfg. In addition, I tried to change port 9999 to other ports (both in mm.cfg and in Flash Builder). I also verified that the location of ProfilerAgent.swf appears in trusted locations of Flash Player.
I would be very grateful if someone could help me to solve this problem.
Thanks,
Valeria

This sounds like something has gone wrong during installation. CSAR and CSLIBS references should be set up automatically during installation.
There should also be no need to import the Flex SDKs as CS Extension Builder 2.0 ships with them included. It won't do any harm though having the CS Flex SDKs imported.
Can you detail how you installed CS Extension Builder 2.0, please and where you obtained it from?
Here are the installation instructions I would recommend starting from a clean FlashBuilder 4.6 instance:
To install Adobe Creative Suite Extension Builder, download the ZIP file and unzip it into a root location (SDKRoot).
Install Extension Builder in Eclipse with Flash Builder or Flash Builder Standalone:
In Eclipse, choose Help > Install New Software.
In the Install dialog, click Add.
In the Add Site dialog, click Local... to browse to the SDK root folder or enter the URL of the update site.
Name the site CS SDK and click OK to confirm the changes.
Select the new CS SDK site in the "Work with" field.
-- Select all the Adobe Creative Suite Extension Builder components.
-- Click Next to confirm the selection.
In the Install Details review dialog, click Next to confirm that you want to install all the components listed.
Accept the terms of license agreements and click Finish.
Re-start Eclipse as recommended.
I obtained it from Adobe and installed it using the Help > Install software option, but without unzipping it. Maybe that was it.
Now I've done a clean installation and it works perfect. I did it with administrator permissions, don't know if it has anything to do with it, but I read it somewhere and did so just in case!
Thanks a lot!

Problem running car demo jwsdp-1.3,Tomcat 5.0

Hello. I am having problems running the car demo on the jwsdp-1.3 with Tomcat 5.0.
I get the following error message:
"A jar file containing the Servlet 2.3 and JSP1.2 classes is required to compile
carstore. Please define the property servlet.jar in your build.properties file and ensure
that the file exists."
I replaced the jsf EA 4 with the beta, and cleared out the cache in catalina as per the
installation documents. I am probably missing something here. I checked my path,
(I am using windows xp) and made sure the jsf directory was in the path.
Any help would be greatly appreciated. Thanks in advance.
regards,
cyuno

Thanks for your response.
I changed the path to the tomcat 5.0 that came with the jwsdp-1.3.
However, I am still getting the same error message. I have checked the build.properties file, the path, the path where ant is located, and the path is pointing to the jwsdp-1.3 directory.
I have been working with the examples in the java web services tutorial, and for the most part have not had any problems running the examples using the jwsdp-1.3, ant and tomcat 5.0(except for CH 11, on the jaxb examples)
Thanks again for your help

Problems running Photoshop CS6 under OS 10.8 Mountain Lion

Since updating the OS from 10.6.7 to OS 10.8 on iMacs (21" and 24" Intel 2.4GHz) I have experienced problems running Photoshop. The app boots up fine and I can start a project as normal, but when I click on a tool to change it's usage I get the spinning beach ball, this lasts about 5 - 10 seconds and then the tool drop down menu appears. After this, I get the beach ball appearing every few minutes as I try to work, and the only way to get Photoshop running efficiently is to close it down and then restart.
Any ideas as to the cause? I've read on forums from both Adobe and Apple that apparently there are no compatibility issues between Mountain Lion and CS6 but I never had this problem previously under Snow Leopard.

The next two remedial steps would be to reset all tools by right-clicking here:
and if that does not resolve the problem, reset Preferences;
To reset Preferences:
If Photoshop is already open on your screen, close it (Quit). Then hold down Shift+Ctrl+Alt (Win) / Shift+Command+Option (Mac) on your keyboard and start Photoshop.
A dialog box will pop up asking if you want to delete the existing Preferences file (the "Settings"). Click Yes in the dialog box. The existing Preferences file will be scrapped and a new one will be created.

Problems running servlet due to missing classes?

Hi everyone,
I am doing a project which requires me to convert a java coding into a servlet. This java coding I am working on is some kind of location based service which tracks people (receiving an argument of a string as IP). It imports an external SDK called Ekahau SDK (some off the shelve product). Now I wish to convert it into a servlet so that the function that the java coding performs can be run from a webpage i created.
I have previously posted a thread on this forum called "Converting java coding into servlets?" when I had trouble compiling the servlet. Now that I could compile the servlet already, I still have problems running the servlet from my browser.
The webserver I am using is Apache Tomcat. Previously I was trying Apache HTTP server but since now I need to use servlet, I have shifted to Tomcat instead. I have been getting these "java.lang.NoClassDefFoundError:" when running the servlet from the browser. From the previous thread, I got suggestions from the replies saying that I need to put the jar files I need into my "C:\Tomcat\webapps\try\WEB-INF\lib" directory. I have been looking for the missing jar files from the internet and putting them into my "C:\Tomcat\webapps\try\WEB-INF\lib", but each time after adding a new jar file, I get another new "java.lang.NoClassDefFoundError:". Are the missing jar files really the problems? Cause it seems a bit weird to me that I need some many jar files which I dont even know why I need them for.
The HTTP status 500 error look like this:

Well, it's kind of logical that as you put more jar files (classes) in Tomcat, it changes the error to ask for the classes (inside a jar) it cannot find.
There was a good class->jar finder on the internet some years ago, but i don't remember the address. Try looking for that and search all the missing classes (NotDefined) and their correspondig jar files.
Good Luck!

Any problems running a program compiled with SDK 1.4.2_14 with JRE 1.4.2_08

Hi,
Would there ever be a problem running a program compiled in Java 1.4.2_13 with JRE 1.4.2_08?
Why or why not? No guesses please.
Thanks

No such hope. The alternative to testing is to review changes made to each version leading up to 14. This is spelled out in each version's Release Document. There are a lot of changes. Most will not affect your program. Each change is relatively well described, but your problem will be to decide if your program will be affected by the change.
Or, do nothing, hope like hell that nothing breaks, and have an up-to-date copy of your resume.
If someone came to me saying a program couldn't be tested, I'd have serious concerns for that person's future.

"The upload has failed. There was a problem running a virus scan for the file." any ideas???

"The upload has failed.
There was a problem running a virus scan for the file. "
This is the message i get when tryng to update
any ideas?

Error: "svr.VirusScanExecutionError"
An intermittent problem with acrobat.com's underlying virus scan component causes this issue. This issue happens occasionally on a small number of server instances.
The solution is to update the article again. Trying again typically routes you to a different host in the server array.
