Running LV VI / program from python

Hi,
I have an automation SW written in python and I would like to get my LV measuring capabilities in to that
meaning calling the LV program and get the measured results back to my PY scripts
in LV i use the DAQMX to measure
if someone can help me with a small start programmer that would be helpful
using NI 6289 DAQ MX to measure differential voltage
thanks

You could build your LabVIEW VI into a DLL and easily call that from Python using ctypes.
Attached is a very simple project with two VIs - AddNumbers.vi and SubtractNumbers.vi. You need to create a build specification for a DLL that includes these.
Right Click Build Specifications and select New/Shared Library (DLL)
Change the Target filename to LabVIEWMath.dll (or you have to edit the Python file that I included)
Change the Destination directory to the directory that contains the attached example project (not good practice but convenient here)
Select Source Files
Move AddNumbers.vi to the Exported VIs by highlighting them and clicking the blue arrow
Keep the defaults on Define VI Prototype (make sure you have C Calling Conventions selected)
Repeat the previous two steps for SubtractNumbers.vi
Click Build
Now from a command prompt, change to the LabVIEW example project directory and run the attached script 'Call LabVIEW.py'

URGENT: How to run a Java program from a different directory?

Hi.
How do I run a Java program from a directory that the file is not located in? So lets say im in c:\Java. But the file is in c:\Java\abc\efg\.
What would be the command to run the Java file from c:\Java.
I can't remember it and I need it asap.
Cheers.

If the class you are trying to run is MyApp.class, try
c:\Java\>java -cp abc\efg MyAppThe actual classpath you specify will depend on whether or not MyApp.class is in a package (I've assumed it isn't) and whether or not any 3rd party jars are involbed (I've assumed not).
Edited by: pbrockway2 on Apr 1, 2008 6:42 PM
The command arguments read as "Run the MyApp class using as a classpath abc\efg relative to here (c:\Java)".

Running an External Program from Batch on Windows Server 2008R2 Failing

Hi,
I am trying to run an external program from a batch job and it is failing with this error message:
Ext. prog.: ERROR: Input redirection is not supported, exiting the process immediately.
Ext. prog.: External program terminated with exit code 1
The program I am trying to run is: timeout
This command works on the OS: timeout -t 30
I have setup the step to look like this:
Under External Program:
-Name: timeout
-Parameter: -t 30
I have also tried:
-Name: timeout -t -30
-Parameter:
I am running ECC 6.04 on top of Windows Server 2008R2 with SQL Server 2008R2.
When we were running in Server 2003 on ECC 6.0 I was able to use the Sleep program just fine in the same manner. I have found out that sleep is not available in server 2008. It was replaced with timeout.
After an update to EHP4 and moving to Windows Server 2008R2, Is there any pre-work that needs to be done on the SAP or Windows side before we can run external programs?
Thank you,
Neil

No - this is no more true like that since Windows 2008, it's a bit more complex:

Add the policy using group policy editor (gpedit.msc)

Run Child Concurrent Program from Main Concurrent Program

Hi,
I'm trying to run Child Concurrent Program from the Main Concurrent Program as below, could you suggest me on below.
Database:10g
Main_Concurrent_Program
=================
1) Will update staging table XXID_PO_ITM with Batch_id = 1,2,3,4,5
This staging table has 1000 rows, so every 200 rows will be updated with one of the above batch_id
This logic is working.
Child_Concurrent_Program
================
2) Above Main Concurrent Program should call below Child_Concurrent_Program.
This Child_Concurrent_Program will have parameter batch_id (based on above batch_id)
So, this Child_Concurrent_Program should kick off with batch_id = 1
Simillarly, Child_Concurrent_Program should kick off with batch_id = 2
Child_Concurrent_Program should kick off with batch_id = 3
Child_Concurrent_Program should kick off with batch_id = 4
Child_Concurrent_Program should kick off with batch_id = 5
Could you give me some suggestions on this?
Thanks.

Check with FND_SUBMIT for submitting a concurrent job using child dependecies. Keep in mind, that once you call the API ... it spawns it's own thread and and becomes an autonomous process. Control is no longer maintained within the calling package.
procedure submit_interface_data(p_schedule_date in date,p_mm_header_id in number,p_req_id out number)
is
v_user_id            number;
v_application_id     number;

Problem running a concurrent program from Reports

Hi,
I've come across a problem while running a concurrent program from Reports. The report is executed OK and at the end, I call a concurrent program by firing fnd_request.submit_request. I catch then the req_id returned and it gives me 0. I tried to replace the concurrent program, which is a UNIX shell script, with just a simple script that echos "hello", but anyway, I get 0 as return value from fnd_request.submit_request.
The next step I tried to set apps_initialize with proper vUSER_ID, vRESP_ID and vRESP_APPL_ID, but did not get away with that. My last try was to hardcode vUSER_ID to a sysadmin user, in case this was rights-related issue but did not work as well.
Am now looking into a possibility of actually getting the error, why it failes. I found some posts where FND_MESSAGE.RETRIEVE and FND_MESSAGE are used but this apparently does not work under Reports (am using reports builder v. 9.2.0.4.0).
Any suggestions how to solve this issue?
Thanks,
David Lacina.

Hi,
Make sure that the concurrent program you are calling exists (case sensitive) and is enabled.
Create a PL/SQL package and use that to call your request - the you'll be able to use fnd_message.

Running a java program from an icon

I want to run my program from an icon on my desktop. I have a .bat file that I've built a shortcut to and it works.MY GUI program does display and run when I click on the icon. The problem is that the DOS window also shows up behind my GUI.
Is there anyway to prevent the DOS window from showing? Or is there another way to run a Java program without resorting to a DOS command line or running it through FORTE or another IDD?

Chris's solution worked well, with one small problem. Once my GUI starts, it takes up the whole screen. Normally when I run it, it appears as a small window.
not a big problem, I can reduce it easily after it starts. But does anyone know a way to make it come up in the reduced size it norally comes up in when I run it from my IDE?

Running a ProC program from Apps

Dear all ,
We have developed custom Pro C Program. It's a huge scheduling program which does somany calculations and prints the log in the Concurrent Program Log using Printf statement.
Whenever we run this program from the Backend using telnet login command prompt , it finishes very quickly.
But the sametime ,if i run the program from Oracle Applications front end using a Concurrent Program, it takes a lot of time to complete.
Can anyonw let me know, Why there such a difference between running from backend and Front end?
Is it anything to do with some memory setting or Log file writing.
Thanks in advance.

Can we run external mail program from JSP / Servlet deployed on tomcat

Hi folks,
Had a tough time getting JavaMail API to work, finally when things seem to be working
there were some issues with the vendor's server, so finally gave up the idea.
On the server Apache and Tomcat are integrated via mod_jk and currently I redirect to a php page
which acts as a helper to send mail, however for the given business needs and server's limitations
there are potential security holes.
So I was wondering if I could directly execute the linux sendmail program from JSP/Servlet
as we would in a standalone java program or do we need special settings on Tomcat to execute external
programs.
Please let me know your views / ideas / comments on this
Thanks in advance

Hi
It's not designed for you to be able to do this, it needs to run through 10gAS or 11gWeblogic.

How to run a concurrent program from Menu List

Hi Guys,
I am working in HRMS. And did the following steps.
1. Created one concurrent program "Payroll Variance Report" as per customer's requirement.
2. Now user wants me to luanch this consurrent program from the People Form i.e. Reponsibility->People Form (on the same form, on the top of it 'Tools' bar is there where I need to attach one prompt "Pyaroll Variance Report" to its list). The moment user clicks on this "Payroll Variance Report" option of 'Tools' list, it should launch the concurrent request. I hope I make you understand my requirements. This is very urgent. Kindly give me you suggestions.
Looking forward to your replies.
Thanks
Sunil

Use FND_REQUEST.SUBMIT_REQUEST API.

Launching programs from python and ncurses

I've made a little menu launcher with python and ncurses. It works most of the time, but occationally it does nothing when I select a program to launch.
This is how it works:
1. A keyboard shortcut launches an xterm window that runs the program.
2. I select some program, which is launched via this command:
os.system("nohup " + "program_name" + "> /dev/null &")
3. ncurses cleans up and python calls "sys.exit()"
The whole idea with nohup is that the xterm window will close after I select an application, but the application will still start normally (this was a bit of a problem). This works most of the time, but sometimes nothing happens (it never works the first time I try launching a program after starting the computer, the other times are more random).
So, has anyone got an idea of what's going on or a better solution than the nohup hack?
The whole code for the menu launcher is below. It's quite hackish, but then again it was just meant for me. The file's called "curmenu.py", and I launch it with an xbindkeys shortcut that runs "xterm -e curmenu.py".
#!/usr/bin/env python

"Gimp", "gimp", "Vlc", "vlc", "Skype", "skype"]

stdscr.addstr(iter_step + 1, 1, string, curses.A_REVERSE)

Error when running mortgage calc program from DOS prompt

I have a GUI Mortgage Calculator program. It probably isn't the most efficient use of code, but it gets the job done. I am running java SDK 1.6.0_06. This is a class assignment. We are to compile the code and post the .class file for our team members to run. I am trying to get the .class file to run after I compile it with javac.

The class is not in your classpath. Likely you blew away your classpath with some silly environment variable.
If you are in the directory where your class file is then execute
java -cp . manchorMortgage3and it will work. (Note the -cp . which tells java to include the current directory in the runtime classpath)
