Can LabVIEW variables be used like those found in a Java program?

I created a decoding program in Java that reads in a certain number, or code, and returns the decoded version of that number.
I tried initially to create this program inside of LabVIEW itself but was hindered by my lack of familiarity and knowledge of what LabVIEW can and can't do and how to approach the problem in LabVIEW.
My stumbling blocks in LabVIEW seem to be the arrays and working the variables. I'm probably approaching this completely wrong, more than likely because I'm trying to think in Java rather than LabVIEW.
Any help that can be given is most appreciated. Also I have attached a text document with my Java code in it. It's not perfect but it works.
If I need to clarify anything just ask.
Once again thanks for any help in advanced.
Solved!

In LabVIEW the wire is the variable. The way you pass parameters to functions (subvis) is with a wire through the connector pane. Same for returning results.
Forget that local variables exist! A lot of new programmers that come from a text based programming background discover the LabVIEW local and global variables way too early. Like duct tape they can be useful. But it is possible to write huge complex applications without touching them. And the code is much simpler than programs of less complexity that make extensive use of locals and globals.
Since you are new to LabVIEW you can become a very good programmer if you keep the following in mind. It is a little confusing but "local variables" and "global variables" are not really variables in labVIEW like they are in Java. The wires are the variables. Those rectangle things you create from controls or indicators are more like a function for that control or indicator. They can not exist without an owning control or indicator. It is unfortunate that they are called variables but they are a relic of the stone ages when code was carved into cave walls.

Certain web forms have formatting options like those found in Microsoft Word. They don't appear when I use Firefox, but do with IE of course. Is there a way to get it to display?

That formatting feature for text areas is known as Rich Text editing. Easy to enable on the web page with one line of code to tap into the Midas package that Mozilla uses, but the users can't enable it themselves from within Firefox.

Can LabView 2013 be used to develop blocks for Lego LabView Education EV3?

I would like to interface some custom sensors to the Lego EV3 brick. Can LabView 2013 be used to build Blocks for Lego LabView EV3 software?

Please note Mac OSX users using LabView 2013 Student Edition -- you CAN use the new EV3 modules but you must install f1 patch first.
I installed NI LabVIEW 2013 LEGO MINDSTORMS NXT Module f1 Patch.
Then
NI LabVIEW 2013 Module for LEGO MINDSTORMS f2 Patch
Now I can program for LEGO EV3, download to EV3 and it works all from the LV 2013 Student Edition (UK).

Can mac mini be used like a NAS for a media center?

Hi everyone,
i'm new to macs and am considering purchasing my first one. i am setting up an audio system with a digital media player/reciever (Linn Majik DSM) and i was recommended to use a NAS for storing music files. I got the suggestion to use a mac mini instead (small form factor, low energy use and also get a 'full computer'). Does anyone know if a mac mini (or mini server) can be used like a NAS to house music files. also, would this play nicely with other computers on the network (windows7). thanks in advance.

I've been using a mini primarily as a media server in my family room for 5 or 6 years. It is connected directly via HDMI to my receiver which is connected via HDMI to a TV.
For music, you can control iTunes with an iPad/iPhone using the built-in OS-X iTunes remote server, works fine. For video, the mini really doesn't cut it even when connected to an HDTV. (at least the late 2011 with video card doesn't). The video quality is OK, but not as good as a BR player.
I use my Bluray player as a UPnP device and haven't found a Mac server that gives fully customizable UPnP menus. However, the Mezzmo server (windows only) does, which adds a bit of complexity but is worth it to me.
My Mac does not show up as a UPnP device, you will need a server of some kind.

Using the Insert statement in a Java program without hardcoding the data

hello.
this is james mcfadden. i have developed a program called Demo.java, which is used with another program called QueryTableModel.java (a program that allows data to be viewed in a JTable). The Demo.java program displays a menu, connects to a database, allows the user to add data into the database and allows the user to view data that is already in the database. I have a problem with the Demo.java program. I have hardcoded the Insert statement in it. How do you use the Insert statement to put data into a database without hardcoding the data?

To generate a wsdl using JAX-WS in JBOSS with java program but without EJB

Hi,
I am using JAX-WS to generate webservices using JBOSS application server by writing a java program.
My sample java program includes :which takes an i/p name as string and displays out put as "Hello name",with the use of annotations.And,also have written web.xml for it.If I start JBOSS without adding project to it,it is starting.BUt If I add project to it the server is not publishing.Its getting like:"publishing JBOSS 4.2.2....:waiting for virtual machine to exit".
I have followed the link:*http://www.javabeat.net/articles/2007/10/creating-webservice-using-jboss-and-eclipse/3*
to do this,where in it was given that by means of auto build process of eclipse IDE war file generates in default jboss folder.But which is not happening,so that,am unable to generate wsdl file..
Can any body help me?
1) why jboss is not publishing after adding project to it?
2) why war file is not generating in the default jboss folder?
Regards....

Yeah sure!!
Overall picture: I wish to expose my OSB services to the third parties using OCSG. For that I've created the Communication services corresponding to each OSB service.
Problem: Integration with the OSB.
At the OSB side I've got JMS queues which interacts with other existing systems in my SOA enviornment. But I'm not getting how to get the OCSG application- triggered request messages in that queue? Please help.
Also I've read about the SOA facades for integration with OSB.Which of the two approaches you will suggest?

Using an SQL table in a Java program?

Hello, I am quite new to programming and would like to know if it is possible to have an SQL database as a backend, linked to my Java program?
If it is pobbible, could someone give me breif overview of the procedure.
Much appriciated.
Thankyou

Yes, use JDBC:

How do i use an import statement in a java program

I need to write a java program which will connect to the Database but i need to do an import like in DB2 which will load data to the table.
How do i execute that import statement

Are you saying that you need to add rows to a table in DB2 via a Java program? If so, you need to look at the JDBC API, (available on this site along with a bunch of tutorials). If not, post again with a clearer description of your problem.

Can we get file name which we are compiling in java program

Hi,
I want to know if we can get filename(when compiling) or jarfile(when running) which we are compiling in the program itself.
EX:java -jar myjar.jar
How can I display jar file(i.e myjar.jar) in my program
ex:sop("file which compiled is:"<filename>);

can you rephrase the question in english, please!!

Can environment variable be used in Windows

Can an environment variable be set and used in Windows for compiling.
For example, instead of typing in something like
javac -classpath c:/java/j2sdk/xml/lib/jaxb.jar MyProg.java
can I set an environment variable (call it "ev")
to c:/java/j2sdk/xml/lib
(or would it be c:\java\j2sdk\xml\lib)
so that something like one of the following (which one?) will work:
javac -classpath ev/jaxb.jar MyProg.java
or
javac -classpath %ev%/jaxb.jar MyProg.java
or
javac -class path %ev%\jaxb.jar MyProg.java

Don't know - best way to find out is to test.

Can cFP-2020 be used like a FP-1600 without a downloaded vi

Is it possible to use a RT FieldPoint interface module like a non-RT module? I want to adapt some code to RT but would like to transition to the FieldPoint hardware. Is it required that the cFP-2020 module have a downloaded vi to operate?

Hello notaclue,
Khalid is correct, you do not have to download a VI to the controller to use it. There are a few ways to communicate with your Fieldpoint bank. You can target the controller with LabVIEW RT and then when you click run on your VI, the program will run on the controller without you having to actually transfer the VI to the target. It is actually running embedded on the controller but is not stored there after you restart the controller. See chapter 4 in the cFP-2020 User Manual for more information. You can also build the application to the controller so that it is stored there and has the ability to start upon boot up of the controller. The last way I think may be what you are looking for, which is to use the Fieldpoint VIs without targeting the controller. You can just access the channels of the bank using IO Points. This tutorial gives a nice explanation of how to do this.
Thanks,
Laura

Can LabVIEW Mathscript be used with Speedy 33?

I am having SPEEDY 33. Whether I can program Mathscript functions using LabVIEW 8.6 or 2009? Or any solution to include Mathscript in SPEEDY 33?

If your intention is to do this:
v_query := 'SELECT rp.usr_id, rp.sun_sft_cat, rp.sun_start, rp.sun_hrs,' ||
' rp.mon_sft_cat, rp.mon_start, rp.mon_hrs,' ||
' rp.tue_sft_cat, rp.tue_start, rp.tue_hrs,' ||
' rp.wed_sft_cat, rp.wed_start, rp.wed_hrs,' ||
' rp.thu_sft_cat, rp.thu_start, rp.thu_hrs,' ||
' rp.fri_sft_cat, rp.fri_start, rp.fri_hrs,' ||
' rp.sat_sft_cat, rp.sat_start, rp.sat_hrs,' ||
' rp.sun_sft, rp.mon_sft, rp.tue_sft, rp.wed_sft,' ||
' rp.thu_sft, rp.fri_sft, rp.sat_sft, nvl(ei.wip_permanent_sched_seq, 0)' ||
' FROM ' || :b0 || ' rp, wip_emp_information ei,' || --- Note the bindvariable...
' wip_emp_status wes, wip_emp_status_type west ' ||
' WHERE rp.usr_id = ei.employee_id' ||
' AND wes.employee_id = ei.employee_id' ||
' AND wes.status_type = west.status_type' ||
' AND west.description = ''WAREHOUSE EMPLOYEE''' ||
' AND wes.effective_date = (SELECT MAX(wes2.effective_date)' ||
' FROM wip_emp_status wes2' ||
' WHERE wes2.status_type = wes.status_type' ||
' AND wes2.employee_id = wes.employee_id' ||
' AND wes2.effective_date <= trunc(SYSDATE))' ||
' AND wes.status = ''Y'' AND rp.wk = 1'; -- wk = 1 is next week's schedule
OPEN rp_sched_cursor FOR v_query USING i_server;Then the answer is: no, you cannot do that.
But my question then would be: why would you want to do that?
I assume you don't have that many "different servers". One cursor per server won't hurt you.

Do not do this... TM works best on its Own Dedicated Hard Drive.
Would suggest another EHD for your windows usage.

Can LabVIEW variables be used like those found in a Java program?
