How use System exec.vi...

hi,
i want to run a shortcut from a labview application. i know the command line to do this from MS DOS but i don't understand how works System exec.vi.
Could you help me giving some example?
Thank you

Use the command "start <path to shortcut>", or "cmd <path to shortcut>", as explained in this document.

Enter password to a program using system exec

Hi,
I have a program that I am running using SYSTEM EXEC.VI. The VI runs ok but asks me to enter a passowrd. If I do this, the VI continues and completes the test. My question is... how can I add the password automatically using SYSTEM EXEC.VI without the user typing it in. I have tried a carridge return and then the password (in the comand line) or even typing the password into the STANDARD INPUT and have even tried creating a batch file but no luck
regards
Chris

How does System Exec VI identify Standard Error within cmd code?

I am using the System Exec VI to control a USB to serial adaptor program header, I have sucessfully written a .BAT file to call the CMD commands (the .exe I am running uses "-option" commands and the help file reccomends to do so) and it functions perfectly. My only issue is identifing errors. The "Standard Error Out" on the System Exec VI never outputs anything. Yes the wait until completion is TRUE and my standard output functions fine. I am curious as to how the System Exec VI identifies errors from the command prompt and why my errors are not showing up. I am currently using multiple match pattern string functions to identify the possible errors from my standar output for the time being but I would like to simplfy my code a bit and clean it up if at all possible. Not to mention there are most likely several other errors that could occur that I may have not identified. Some examples of stanadrd output errors i can get include include:
{C:\Documents and Settings\owner\Desktop\RACK LINK>C:\DCRABBIT_10.66\Utilities\clRFU.exe "" -s "0":115200 -v -vp+ -usb+
.bin not found
C:\Documents and Settings\owner\Desktop\RACK LINK>pause
Press any key to continue . . . }
or
{C:\Documents and Settings\owner\Desktop\RACK LINK>C:\DCRABBIT_10.66\Utilities\clRFU.exe "C:\Documents and Settings\owner\Desktop\RACK LINK\Calibration_v030.bin" -s "4":115200 -v -vp+ -usb+
Rabbit Field Utility v4.62
Installing Calibration v0.3.0
Sending Coldloader
Error: No Rabbit Processor Detected.
C:\Documents and Settings\owner\Desktop\RACK LINK>pause
Press any key to continue . . . }

I think you should use error handling in batch programming, see this link http://www.robvanderwoude.com/errorlevel.php

Calling a VI which uses "system exec.vi" with LabVIEW run-time engine as adapter

Hi,
My TestStand sequence calls a VI which includes a call to "system exec.vi". When I try to load it in TestStand and if LabVIEW adapter is set to run-time engine, I get an error message "Unable to load Vi...". If I switch the adapter to "Development system", then it works fine.
Is there any way to use "system exec.vi" in a VI which is called in TestStand with LabVIEW run-time ?
Thanks,
Alex

Sand Box has stopped working error when using System Exec.vi with wait until completion is true

I get the following error message in Windows 7 "Sand Box has stopped working" when using System Exec.vi with wait until completion set to true, if I set it to false there is no error message.

Hello JJVerdi
mmm well System Exec.vi simulates a DOS command window, can you run the sandbox from the cmd window using the same commands without any errors?
you may take a look to this KB, it may be related to your issue:

Use System Exec IrfanView to open JPEG file

I am trying to use System Exec to call Irfanview to open a Jpeg file, and the following error occurs:
"Error 2 occurred at System Exec.vi. Command was "iview32 c:\test3.jpg /hide=3 /pos=(30,30)"
"LabVIEW: Memory is full."
"NI-488: No Listeners on the GPIP"
I then tried to add "cmd /c" in front of the command but the DOS windows just flash open and close and then nothing happen.
I have no problem opening the jpeg in DOS command window.
Anyone can help?

you do not need to specify the full path as long as you have the path in your path variable
I think the problem may be that you are using the wrong program name I think it is i_view32 not iview32

How to hide command prompt window when using system exec

Hello, I'm using the system exec VI to do some file transfers for a LabVIEW application. I'm worried that the black command prompt window with white scrolling text that pops up when system exec is called might frighten the non-tech savy users of this LabVIEW application. Is there a way to hide the command prompt window?

Running Oracle Reports via a client using system.exec call from war file

Hi all,
I am trying to deploy a war file application to a J2EE 10.1.3 application server. The deployment successfully completes. However testing the application fails.
When testing, the application reveals that calling a Oracle Reports 6i client (using a cmd line exec) from the war file returns application errors. The errors we get from executing the call below (using debug statements), creates this error:
OperatingSystemCmd: cmd = D:\Oracle\Dev6i\BIN\rwcli60 MODULE="CLTMLST" USERID="<userid>/<pwd>@<db>" DESTYPE="FILE" DESFORMAT="PDF" DESNAME="<path>\<pdf filename>.PDF" PARAMFORM="NO" BACKGROUND="NO" SERVER="r6i.world" TOLERANCE=0 ADVCODE="<param>"
OperatingSystemCmd: Command returned 3
WrsRunReport: Done executing report
WrsRunReport: Error running report Return code 3
Error on Screen is REP-0178 : Cannot connect to reports service.
However running the same command from a operating system command prompt in windows reveals that the command runs successfully.
Is there any particular OC4J J2EE settings that are required to get this statement to run properly?
Any help is most appreciative.
Cheers
Rodney

Hi All,
From much research and experimenting to get this to work I looked at the java.lang.Runtime class and noticed that seperate processes can be started using this very important Java class.
The first thing that I experimented with was in regards to seeing the environment OC4J runs against. Using the java.lang.Runtime class I executed a standard "cmd /c set" command in my Windows environment, and noticed that Oracle Application Server uses its own environment and not a standard windows login environment for its OC4J containers. Apache Tomcat on the other hand uses the standard user login environment.
So to get the application to be able to work properly we needed to override the particular environment the process needed to be able to get it to work. There is a exec command which allows you to override completely the environment for a process you would like to run. This method call does not in any way shape or form change the standard OC4J environment. This was done by executing the same "set" but with the overriden environment. Note that no environment variables from the OC4J container are carried into this new environment.
Cheers
Rodney

How use system.out.println with a Java Swing Applet?

Hi guys,
I was just wondering what can I use to view output on the Java console with a Java Swing Applet?
At the moment I'm using a JTextArea within the Applet for debugging but I want output to appear in the browser java console but system.out.println doesn't work.
I'm viewing the Swing Applet on Netscape 4.7 browser.
Any ideas?

System.out.println()s work fine! I'm guessing that your problem is that you are looking at the wrong console window!
You're using the Java Plug-in, right? On Windows, go to your Control Panel and double click "Java Plug-in". You should find a checkbox option to "Show Java Console" - make sure this is checked. Next time you fire up you JApplet, you should see a Java Console window popup.
Hope this helps!

If I understand the question correctly you need to add an invoke node at the end of your application to exit. Depending on the whether it is running as a stand alone application or within LabVIEW it will either exit or stop execution. I've attached the VI I use in my applications.

How to Launch a "setup.exe" with LabVIEW app? No luck with System Exec.vi

I've got an application that I'm trying to update with a separate LabVIEW application (the "Updater"). It's the "Check for Updates" capability you see on other major apps.
Here's the glitch: When the Updater tries to launch "setup.exe" using "System Exec.vi", The installer seems to catch the attempt and pops a dialog titled "Windws XP Setup" saying "Please go to the Control Panel to install and configure system components". The install does not begin and the installer closes (if it was ever open!).
Running the same installer by double-clicking the "setup.exe" file from windows runs just fine.
Here's the question: "How can a LabView app launch an installer?"

Could you show the code.
Look at the path where you want to run the code.

Creating a delay in labview until a c program completes in system exec.vi without using "wait until completeion"

I want to run two related C programs. The second one reads a text file that the first created. So I need to wait until the first is completed.
I use "system exec.vi" and I know I can set "wait until completeion" to true, but this way I won't see the screen and the C program announcments. Someone has an idea?

Hi Dror,
my idea: just wait for the text file created by the first C program. Check for the presence of this file (maybe using 'list directory') or check for the size of this file...
Best regards,

System Exec use all resources system if "wait until completion" is true !

Hello,
I use the function "System Exe" since a long time to launch various executables since Labview.
The " waint until completion " boolean is true, because I have to wait the end of the external executable to continue.
Big problem: the function " System Exec " use all resources system, by waiting for the end of the external program.
Is it a bug of this function ?
In my example, "System Exec" launches only the notepad (LV 8.2 on XP)
Thank you for your suggestions.

Bug system exec.vi ‏17 KB

Thanks to both for your speed.
In fact I had simplified my vi to target the problem.
I use System Exec to launch another executable, made possibly with labview, but with passage of parameter. (Ex: - " / string:init ").
In the literature Labview it was made with the method cmd / x / c start by putting twice the path of the executable.
In this method a waiting time in the recent system exec function was effectively missing.
But effectively, today, it is enough: "c:\myexe.exe" - " / string.init " to launch and to pass a parameter.
You have both reason and I thank you sincérement.
Very cordially.
