Calling Python Script from LabVIEW

Hello Everyone,
I want to call the Python script from LabVIEW.
I tried with using at the command line but i am unable to run that script file..
i have gone through LabPython but i am unable to call the scripts from there also..
If someone has an example of a VI which invokes a python script, it will be very helpful...
Thanks a lot in advance

One way is to create a client server app and to send arguments to python (and back) over TCP/IP. This work very well.
There is an example on the old OpenG Website about this. Look it up.

Calling perl script from labview

Hi,
I have a perl script and I would like to call the perl script from Labview

Thanks
SL Ong

Hi,
Thanks for the reply from everyone.
The attached is my code to call Perl script and after calling this, I need to query the Perl Script by sending command like @help. Do they have a way to query the Perl script by sending command like @help and get the return result.
I think Joseph you are right, but how do I get the return result if I invoke it in a separate dos session.

How to call a python script from a TestStand sequence?

Please tell me how is it possible to call a python script from a TestStand sequence.
Thank for your help in advance.
Imre

Here you can find some information about Python and LabVIEW:
http://forums.ni.com/ni/board/message?board.id=170&message.id=124424&query.id=149647#M124424
If you have LabVIEW, you could use LabVIEW steps to call your Phyton Scipts.
Another solution would be, to do, what is decriibed in the thread directly in TestStand:
You can call a dll or .NET assemblies directly from teststand, or use the "Call Executable" TestStep.

Call a python script from perl file

This is my first post and am not sure if this is the right forum to post this query. If this is not the right forum, pls redirect me to the appropriate forum.
Query :
I have a python script which was created through WLS console's recording feature. I have to call this python script from a perl script (dte topo block).
Any pointers towards how this can be achieved ?
Thanks,
Madhusudan

I am using inline python to execute python statements directly from the perl script. However, i get below error :
[maddeshp@slc01auw forDTE]$ perl -c intro.pl
Can't find string terminator "END_OF_PYTHON_CODE" anywhere before EOF at intro.pl line 2.
Has anyone run into this problem ? Any suggestions on fixing this ?

Controlling dialog boxes in a DIAdem script from LabVIEW

I have a DIAdem script that prompts the user for the data file it will process. The datafile was created from a labview test routine. I can now run the script from LabVIEW using the "DIAdem Run Script.VI", but in the interest of automation, I would like to have LabVIEW place the filename in this dialog. I would like to keep the dialog in the script, since sometimes we run this script manually. (without LabVIEW)
Bill W.

Bill,
Which dialog are you using to prompt for the file name? It
appears that you cannot send any information to the script through the
Run Script.vi. However, you can call automation commands using
the "DIAdem Run Automation Command.vi". If you want to pass data
to the script, then you can set a Global Variable, or a DIAdem Script
Variable. As an example, you could use the global variable, T1,
and send "T1 := 'myfile'". When the script is executed, that
variable will be accessible within the script and it will be set to
"myfile". You could also set the FileDlgName variable to your
file name. Then it may be possible to send those variables to
your dialog so that they are automatically populated.
Good Luck!

Hi,
You can call by creating external window method.
create LINK to URL or LINK TO ACTION according to requirement, for this. write code in onaction of that.
data: iv_url type string value 'http://<server>:<port>/sap/bc/gui/sap/its/webgui?~transaction=*se38 RS38M-PROGRAMM=rsparam;DYNP_OKCODE=SHOP'.
data: api_component type ref to if_wd_component,
          window_manager type ref to if_wd_window_manager,
          window type ref to if_wd_window.
api_component = wd_comp_controller->wd_get_api( ).
window_manager = api_component->get_window_manager( ).
window = window_manager->create_external_window(
                 url = iv_url
                 modal = abap_false ).
window->open( ).

Calling GUI Scripting from ABAP program

Is it possible to call GUI Scripting from ABAP and thus to use GUI Scripting as an alternative to CALL TRANSACTION?
Is the class CL_JAVA_SCRIPT suitable to access GUI Scripting engine? Accessing ABAP data object would work as well in this case as i think. What SAP Logon and WAS releases are required? Is the 6.20 release sufficient for this case?
I would appreciate if somebody could post an example.

Hi,
CL_JAVA_SCRIPT has nothing to do with SAPGUI Scripting.
Calling SAPGUI Scripting API from ABAP could be possible for programmes experienced with OLE automation calls from ABAP coding.
The hardest thing will be, to access the scripting engine handle as an entry point. Once you have a handle in your abap session, any api function can be invoked.
Best regards
Jens
BTW: SAP testtool eCATT does call SAPGUI-Scripting from ABAP.

Calling Ant script from Jdeveloper

Hello Gurus,
I am trying to call Ant script from Jdeveloper.
I am able to call it when i don't use any javac in ant script.
But as soon as i include a javac command
<javac srcdir="${src}" destdir="${build}"/>
I get below error
C:\ant\windows\svn\AntJava\Project1\build.xml:20: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "C:\Oracle\jdk160_24\jre"
Needless to say i already have implemented all the steps mentioned in the internet.
I have my JAVA_HOME correctly set in my PATH environment variable.
I have tools.jar in the CLASSPATH
Please give a solution from JDeveloper perspective and not a generic one as i am done with all the steps provided in internet.

Calling shell script from apex application

Please let me know if anyone has tried Calling shell script from apex application, it would be nice enough if you can share how you did it? Thanks

Hi,
Requirements
* CREATE JOB (10g Rel.1)
* CREATE EXTERNAL JOB (10g Rel.2 / 11g)
* EXECUTE on dbms_scheduler (granted to public by default)
Since Oracle 10.2.0.2 the commands are executed as user nobody.
Code:
--Create a Program for dbms_scheduler
exec DBMS_SCHEDULER.create_program('RDS2008','EXECUTABLE','c:\ WINDOWS\system32\cmd.exe /c echo 0wned >> c:\rds3.txt',0,TRUE);
--Create, execute and delete a Job for dbms_scheduler
exec DBMS_SCHEDULER.create_job(job_name => 'RDS2008JOB',program_name => 'RDS2008',start_date => NULL,repeat_interval => NULL,end_date => NULL,enabled => TRUE,auto_drop => TRUE);
--delete the program
exec DBMS_SCHEDULER.drop_program(PROGRAM_NAME => 'RDS2008');
--Purge the logfile for dbms_scheduler
exec DBMS_SCHEDULER.PURGE_LOG;
This is one way as suggested by Trent.
We can also achieve as follows.

Calling PERL script from scheduler

Hello All,
I am trying to call PERL script from dbms_scheduler which makes the database connection using DBD module to read some values to perform the operation. My scheduler job kept failing with the following error:
ORA-27369: job of type EXECUTABLE failed with exit code: No such file or directory
STANDARD_ERROR="install_driver(Oracle) failed: Can't load '/usr/lib/perl5/site_perl/5.8.8/x86_64-linux-thread-multi/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: libclntsh.so.10.1: cannot open shared object file
It can't open libclntsh.so.10.1 file when I run the job, I guess because in job session, it creates a new shell and doesn't inherit the .profile and none of the environmental variables get set. When I run the PERL script manually it works because of all the env variables, so I put all those variables from my .profile into PERL script itself using ENV function but it still doesn't work, failed with very same error. And yes I do set LD_LIBRARY_PATH to point to $ORACLE_HOME/lib directory. Moreover, if I run the PERL script manually from a shell where I dont inherit .profile, it fails with very same error, so it is related to the environment issues but I have no idea how to fix it. I read somewhere the setting those env variable in PERL script itself doesn't help because by the time PERL get executed all the compilers are already initialized and and they don't use those environement variables anymore then. So the question is how to make it work?
I would really appreciate if someone can help me fixing this, it's gonna change my life here :)
DB Version: 10.2.0.2 (also tested on 11R2, same problem)
OS: SUSE Linux 64 bit
And here is my libclntsh file in $ORACLE_HOME/lib
$ls -l libclnt*
