How to call another program from LabVIEW?

Hi!
Is there anyone that can answer my question? I have found a similar thread where the user needed to call labVIEW from some program but I want to do the opposite.
I made a program in labVIEW that communicates via COM-ports (serial communication) with the processor I use at the job (Ubicom´s IP2022).
Now I want to add more funcionality to this program. I want to be able to program re-program IP2022 through this LabVIEW application.
The programming is done via an Ethernet-dongle. I start a program called IP2kProg, I write the ip-address of the dongle and the program-file (.elf) downloads at this address. But how can I do this from
LabVIEW, do I need to open IP2kProg or can I send some values to it via LabViEW?
Ant suggestions?
Thanks, Amir

Amir,
There are couple of options:
1. If your IP2kProg program has a command-line interface, you can use LabVIEW's System Exec.vi and send the commands and parameters to it.
2. If the IP2kProg has an API / exported functions, you can call them from LabVIEW using the Call Library Function Node.
Hope this gives you some ideas.

Calling another program and waiting for output

Hi,
I'm writing a program that passes a file created for an application called Net Sim but has to wait for the output. Net Sim lies in another directory from the java files and I don't know how to call the program with the file created as a parameter, such as:
ns2 network1.tcl
where 'ns2' is the dos command to run net sim and 'network1.tcl' is a file passed as a parameter to the program.
I've tried
try{
Runtime r = Runtime.getRuntime();
r.exec(" <directory> ");
}catch(IOException e){
System.out.println("Error " +e);
This doesn't work though and I could use some help, as well as how to save the file created by the program in another directory.
Finally, I need to know how to make the program wait for the output from net sim which is a file I intend to use. Can I do this with a while loop etc.?
I thank you in advance for any help,
Regards,
Gary.

Here's an article from JavaWorld describing some of the pitfalls when using Runtime.exec() that might help you:

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:

Calling another program

Is it possible to call another program (vlc media player in my case) in a VI???I dont want to use the Active X control for playin videos as it does not have much playback functions...

Use the System exec.vi to launch any executable from LabVIEW in your case VLC player. Provide the required inputs path, command line args so that you can obtain the desired functionality.

Calling another program from the current program

Hi all,
In our requirement we are calling another program from our current program .
In the current program( from which we are calling ) we are giving file name in the selection screen
and when we run the current program we are successfully going to other program but our main requirement is to higlight the file name which we had given earlier .
Note : The called program doesnt have any selection screen.

HI
use EXPORT and IMPORT key words for passing data from one program to another program.
as the called program is available in the same session you can use above key words which means you are accessing ABAP MEMORY.
You can also use SET and GET key words which means SAP memory
take F1 help there are examples tooo and detailes explanation abou the same

How to call another view controller's method from a view controller?

Hi,
Iam new to webdynpro . so pls clarify my doubt.
How to call another view controller's method from a view controller in the same Web Dynpro Component?
Thanks,
Krishna

Hi,
     The methods in a view are only accessible inside same view. you cannot call it outside the view or
     in any other view although its in same component.
     If you want to have a method in both views, then create the method in component controller and
     from there you can access the method any where in whole component.

How to call another directory java program?

Hi All,
For Example:
My program is here in two directories.Let Think that directory names like A and B.
Let Program names like Aprog(A directory) and Bprog(B directory).
I want to call Aprog to Bprog method.
How to call?
Plz., help me ASAP.
--Mohan

My program is here in two directories.Let
Think that directory names like A and B.
It's more complicated than that. A java program consists of multiple .class files. In general you have one or more "trees" of directories of .class files, where the structure of the tree reflects the package structure. So a the class file for "org.dingbat.Thingy" is <basedir>/org/dingbat/Thingy.class where <basedir> is some directory on the class path.
So referencing one class from another in different directories requires that the source provides the "fully qualified name" of the class (usually on an import) and making sure that, if it's in a different class file tree, both base directories are on the class path.

How to call external programs?

I have seen people call external programs through LabVIEW and was curious what functions you could use to do this.
I'm pretty sure its using one of the ActiveX functions or maybe 'open application reference .vi'.
Can anyone tell me (or show me) a quick example of how to open an external program (ie excel, notepad, etc) programatically

Kudos for going from "I don't know to start" to "Let's stump Ben" with only the second post to this thread.
I either copy it from an example or try to browse to it.
NOTE:
If you plan to work with MS ActiveX objects, I found it very helpful to do a custom install of Office and make sure the help files for VBA are loaded. These will at the least give you an idea of what the methods are and what parameters go with each.
