Running external applications from LabView

Here are some very basic functions that allow you to start, close, minumize, and maximize external applications.
Not much happening on the front panel, take a look at the block diagram. The string constants are the title of the application as it appears on the title bar when the application is running.
These functions use no other VIs as have been previously seen, BUT they do use the user32.dll which is normally in the windows system32 directory.

Hi Elvis,
I took a look at that example and also found that it was built for SQL server, not necessarily Access. The difference is in the way it stores procedures. I have attached an example program that calls a stored procedure (or query) in Access on a sample database and gets called in LabVIEW. Please try this and let me know what you think! thanks

Run External Application

Does anyone know the best way to connect to an external (non-Oracle) application via SQL or PL/SQL?? I have to run external applications such as MS Word from within an Oracle application. There are several applications which may be used, so I plan to start with a page of options with selection of an option connecting to the external application. Any proven options will be considered.

This may be be very hard to accomplish...
If users are accessing an HTMLDB application, they persumably using a browser. Browsers, by design, aren't allowed to spawn external applications on the client machine-- imagine what would happen if I could put up a web site that opened an arbitrary application on your desktop. In theory, you could probably write an ActiveX/ Java component that could be embedded on pages from HTMLDB and will, with the right security settings, open up application windows. This would be a very complex development, deployment, and maintenance problem, though.
Perhaps if you explain why you want to spawn these applications, we could provide more assistance. It may be as simple as providing a link to a .XLS file stored in the database. When the user clicks on that and downloads the file, the server can identify the content-type of the file and the browser will open the file in whatever application is registered to support that file type.

What is the easiest way to open an application from Labview?

I need to open an application from labview and depending on a user's selection, load one out of a group of files for the application that is opened. I need to know what is the best or easiest way to open an application and load a file that is used by the application based on a selection.

Here is the response that I got from Cognex when I asked them about how to do this. Do you understand what they are talking about?
In order to do something like this you will probably want to look into the Display Control/SDK for In-Sight. The Display Control gets installed along with In-Sight Explorer and includes a control that can be used in an environment like Labview to communicate with In-Sight sensors while the SDK is an enhanced version of the Display Control that gives you more control and functionality. I am not very familiar with the Labview environment so I will give some code snippets in VB.Net and hopefully you can adjust them as necessary. Specifically I see 3 possible avenues to do this:
1) Using the Display Control you have access to many of the dialog boxes that are used in In-Sight Explorer including the Load Job dialog box. You can spawn this dialog box through a line of code similar to cvsInSightDisplay1.Edit.OpenJob.Execute(). I am not certain if the Labview environment will be able to spawn and display this dialog though. 2) With the addition of the SDK (additional purchase) you can directly access sensor properties including the job. There is a method called LoadJobFile to load jobs from on the sensor and LoadJobFileLocally to load jobs from the host machine. A typical line of code might be cvsInSightDisplay1.InSight.File.LoadJobFile("myjob1.job").3) If Labview cannot handle the dialogs and the SDK is not an option for you then you may still be able to do this using Native Mode commands. Native Mode commands are sent through a socket on the telnet port (typically port 23). Keep in mind that you will need to handle the username/password prompt and response when you first open the socket before issuing any Native Mode commands. The command to load a job file from the sensor would be the Load File command which would be a string similar to "LF myjob1.job". The Native Mode commands are documented in the In-Sight Explorer help file.

Is it possible to run an application from a user or container login script?

Is it possible to run an application from a user login script or a container login script?
A "Force Run" application object works fine if the user's workstation is setup to auto-load "Application Window" or "Application Explorer" but in this case I'd like to run an application when someone does a manual login (ie. they right-click red "N" and choose "Novell Login...")
Using a User Package's "Scheduled Action Policy" and the Event=Login also does not work when a user logs in manually. This type of Event seems to only apply when the user first logs into the workstation, not at a manual login.
Thanks,
Marc

Yes, see the documentation:

How to run two applications from same application server

hi,
i am working on oracle application server 10g , is it possible to run 2 applications from one application server by using different url ? but same report server name .
if i can do so plz tell me how ?
regards

hi,
offcourse,you can do this you.you can deploy n no of applications on a single application server.
and even you can run all the reports on a single report server
to the below location.
$ORACLE_HOME/forms/server
create a new enviroment file(for eg fd.env) using the default.env as follows and make the following FORM_PATH and REPORTS_PATH changes in the fd.env
FORMS_PATH=/oraApp/Ora_bi/forms:/oraApp/backup_29_11_2010_0.12/fd/pll:/oraApp/backup_29_11_2010_0.12/fd/forms
REPORTS_PATH=/oraApp/backup_29_11_2010_0.12/fd/reports
similarily create another env file (eg appr.env) and make the above changes in it.
Now make the following changes in formsweb.cfg
for example:
[xyz]
envFile=appr.env(env file name)
form=xyz.fmx(your start form)
lookandfeel=oracle
separateFrame=false
userid=appraisal/[email protected]
splashscreen=NO
logo=NO
background=NO
color=automatic
render=yes
archive=frmall.jar
archive_jini=frmall_jinit.jar,frmwebutil.jar,jacob.jar,ofasIcons.jar,icons.jar,OfasPrint.jar,newicons.jar(these jar file are the images files of your applications..needs to be stored in $ORACLE_HOME/forms/java.
imagebase=codebase
term=frmpcweb.res
baseHTML=webutilbase.htm
baseHTMLjinitiator=webutiljini.htm
baseHTMLjpi=webutiljpi.htm
WebUtilArchive=frmwebutil.jar,jacob.jar
[fd]
envFile=fd.env
form=fd.fmx
lookandfeel=oracle
separateFrame=true
userid=fdmmfsl/fdmmfsl@mmfdlive
splashscreen=NO
logo=NO
background=NO
color=automatic
render=yes
archive=frmall.jar
archive_jini=frmall_jinit.jar,frmwebutil.jar,jacob.jar,icons.jar
imagebase=codebase
term=frmpcweb.res
baseHTML=webutilbase.htm
baseHTMLjinitiator=webutiljini.htm
This depends on your application which your deploying
now for about accessing the seperate application then
use as follows
1st application
http://ip address:7778/forms/frmservlet?config=xyz
2nd application
http://ip address:7778/forms/frmservlet?config=fd
you can even deploy 2 war files on one application server...and you can even make these 2 war files to access the same report server
If you require any other help then do let me know

Can you Launch External Applications From Within InDesign Ebook?

Hi all,
I was wondering if it is possible to open an external application from within an ebook (created with InDesign) e.g. click on a link and have an external ssh client open up for instance?
Thanks in advance for any advice.
Regards,
RG

It's possible to include hyperlinks in an InDesign file and export them in an EPUB file. Since I'm not familiar with working with SSH clients (in fact, I just had to Google it to have a clue what you're talking about), is this something that can be invoked in a standard URL format? If so, you could probably include it.
The next issue is whether the link would work. The link couldn't be used directly in any eBook reader I know of, but at least the iBook on an iPad or iPhone would switch to to Safari to let you follow a URL to its destination. But I don't think that's possible on most eBooks.

How do you pass an ActiveX Variant from an external application to LabVIEW?

Background: I created a LabVIEW ActiveX server. I can access it with my external application (Matlab). I have a control variable in my LabVIEW executable. I want to use Active X to set the value of my control variable from my external application.
Documentation: The only reference in the documentation for this task is in the Using ActiveX with LabVIEW in the LabVIEW 2009 help. It simply says "Use the variant control and indicator to pass data to or from ActiveX controls." I also went through all the ActiveX examples in the example finder and did not find any vis that passed variables using ActiveX.
Questions:
What should my control variable look like in LabVIEW? Should it be a refnum, a variant, or a data type? Does it have to be wired to a vi connector?
Do I need to do any magic on this variable, such as change its properties?
How do I pass the value from my external application to the variable in my LabVIEW executable?
Thank you.

Hello Lyn,
The control variable should be a refnum and it would have to be wired to Automation Open with the correct reference.
Here are some great examples of using ActiveX Server in LabVIEW

Running LV application from remote panel which measures FP through different LAN

My LabVIEW application is running in a PC and it takes measurements from the FieldPoint modules which are connected via the FP-1601 network module.
I want to view and execute the application from another PC using remote panel option. The master PC has two LAN connections, one seperate connection for the FieldPoint module and the second one to connect with other PCs.
But the application returns error while initializing the FP modules when executed from remote panel.
Will the application be able to communicate and take measurements from the FieldPoint module in this case? Please explain.
Thanks for the help and awaiting earlier response.
Thank you,
Rajeswari

In principle this I believe this is a TCP/IP routing issue.
If your fieldpoint unit is connected to one card lets say
Card 01 Host 10.0.0.1 255.255.255.0 ---- Fieldpoint 10.0.0.2 255.255.255.0
Card 02 Host 168.95.0.1 255.255.0.0 ---- Lan 168.95.x.x 255.255.0.0
The routing in the host takes care of which card is used for which network segment.
My guess is that you have not seperated the network segments as shown above.
Is this correct ?

Run External application without Exiting main application

Hi,
I am trying to implement a function that executes the external program from within my java application. I am using windows xp. I had googled for this and found some code but so far I am able to run the application in a condition if my main application exits. Instead I want to run the application without exiting my main application. How can I do that:
Code I am using is:
========================
try{
Runtime.getRuntime().exec("external program");
System.exit(0);
catch (Exception err){
err.printStackTrace();
System.exit(-1);
=========================
my problem is I cannot run the external program without the line "System.exit(0)". If I remove that line, the external program only starts after I exit my main java application. Is there a way to run the external application without leaving the main application?
By the way I am using the latest version of JDK 6 update 2 and Netbeans 5.5.1
Thanks

I tried and I tried and I couldn't make the same problem occur unless I specfically had a long task execute BEFORE calling the runtime command. See the code below:
I tried a bunch of things, including having a GUI run before the Runtime call, after the runtime call. Neither affected the movie from being played.
I tried with different versions of the runtime command, none of it made a problem.
I tried running the application with a long task that would keep the main thread busy for a while AFTER I launched mplayer - no problem.
The only thing that made the app work the way you describe was when I built the long task that keeps the main thread active for a while BEFORE I launched mplayer (which is the state of the code as I pasted it below).
So my guess is that you have a single threaded application and you add the call to mplayer at the very end of your program's execution - thus it doesn't get called until the last thing. My suggestions:
1) Move the call to the Start of your code, not the end
2) Move your other work to a new thread so that it can be kicked off without holding the main thread in check.

            t.printStackTrace();
}I will restate myself:
"I was not able to repeat the problem, except as described, as long as I took the hints mentioned in the article I posted into account and actually put them into action."
Of course, as soon as I ignored those hints, I was able to reproduce the error described above quite easily in all the different tests I made... But I guess the OP implemented those fixes, right? He did say he read the article...

Running external program from Form6i

I have a Form 6i, client server application and from there I launch a window based help system, using Host command.
Is it possible to run both the form application and the help program togather at the same time. As at the moment I need to close the help program to start using my Form based application.
Regards
EVA

Hi,
Thx. for ur reply but I am already using the same host command and it is working fine. But we do have some problems in using the host command like u need to close the external application or o/s based application before working back in forms and also that I would like to use a generic html tag which can be opened in any default browser defined for the system rather than mentioning or invoking explorer explicitly. I am looking for any new builtin available in FORMS6I which can support web integration with the application.
Thx.

If you want to start a Host type command Asynchronously then you can use DDE.APP_BEGIN or the WinExec call in the D2KWUTIL library.

Hi,
it's possible launch an external executable (Es. .\smsclient.exe "3201234567" "SMSClient.exe Tested on %date% at %time%") from script .aef (not from CAD)?

Hi Anthony,
i have developed a Java class how you said me. I receive the sms, if run application from Eclipse. But if I invoke this class from script .aef not operate.

Getting error while running external application

Hi Everyone,
I am using JDeveloper 11.1.1.4. I am trying to run an external application for accessing ZOHO Mail. For this first i created an external application with the details of Login url, Username & Password. Then I embeded this external application to jsf. While running this file i am getting message like " user anonymous not authorized to access external application ZohoMail " in browser. Did i do wrong anything ? ? Please provide information regarding this issue.
Thanks in advance.
Regards,
SEWSupport

Hi,
I created a web application and right click on the project --> new --> General --> ExternalApplications --> ExternalApplication.
In the ExternalApplication registration I declared application name then in step2 I entered LoginURL as http://mail.zoho.com/biz/index.do, Username as LOGIN-ID and Password as PASSWORD. Then i clicked on next --> next --> Finish.
After that i created one jsf page and drag and drop that external application into jsf.
Then run that jsf file, While running the error message is getting in browser.

Hi,
Finally I fixed this issue.
I ran the SybaseServerSync.v35.CAB on the device emulator. Then tried the program. It worked. This helps establish the synchronization between the device and the SUP server. This CAB file can be located at the path <UnwiredServerInstallationLocation>\UnwiredPlatform\ClientAPI\RBS\WM\ServerSync.

That'll pop up another consoleI'm under the impression that the console window he is seeing is the one which cmd.exe opens when it is executing the batch file. And that batch file won't return until the java process has completed because he didn't start it in the background to let the batch file continue and terminate.
So I don't think just simply substituting java with javaw will do much good either. Still think he needs a "start" command in that batch file.
So now he can try:
start java -jar ...
or
start javaw -jar ...Fair point
