VIs with conventional programming languages??

Hi , just assuming myself if there is any possibility of building a vi using traditional programming languages.
Can we write any program in C or assembly language and make it as a NI supported vi like any other normal vi?? B'coz this level of coding is very compact and guess NI also would be doing some kind of this to develop various supported functions and VIs.
Is it feasible???

Did you notice that you can write small programs, such as the one attached as an example, using the Formula node ?
You can also imbed MathLab scripts or their LabVIEW equivalent MathScript in similar text nodes.
And I discovered very recently that SciLab, a powerfull, popular and freeeeee programming language has been opened a gateway into LabVIEW.
Isn't that what you are looking for ?

Large applications - Labview and other programming languages

Hello Labview Users,
as the forum saw this very interesting thread about large applications programmed in Labview
(see: http://sine.ni.com/niforum/niforum?requireLogin=False&forumDU=http://forums.ni.com/ni/board/message?... ) I would like to ask the community about their experiences with Labview applications in combination with other programming languages.
In advance: I have several years of experience in programming Labview applications starting from quick-and-dirty solutions which had to run within few hours and complex test solutions. I saw Labview growing and becoming better with the released versions and lot of things I missed in former times got implemented in the meantime. Actually I have to develop a complexe ATE solution with numerous equipment to control and numerous data to be captured and archived. Despite the Verison 8 I still feel still some drawbacks of the LV concept which let me hestitate to setup the solution completly in Labview:
1) It is alway hard to re-use code of complex applications since it is not possible to do some kind of global search an replace of functions
variables etc. It nearly impossible to re-use approved code structures (e.g a state machine) if the "inner part" is changing more the a little bit.
2) If the application requires a certain flexibility (e.g. exchangeable test equipment of varying vendors) this is hard to implement since you have to define a lot of parameters through your hierarchy if you dont want use global variables which slow down your application and hide
the code functionality.
3) Despite modern PCs the look and feel of LV applications appears somewhat slow compared to other applications. For complex user interfaces the polling methode generates a lot of complex code. (I dont have expierence with the event-structure).
Now my questions:
Do you have experience of implemention of complex solutions dividingthe code modules using Labview and other languages? Which other
languages did you use? Why did you use these languages (speed, flexibility of text based code, available library functions)? Did you found out this to improve your development time and code maintainibility?
(I concider a solution where I do the single tests with Labview-VIs but delegate all the test sequencing and data collection stuff written in PERL which allows really very compact code)
I'm curious what your experiences are.
rainercats

Given that you're asking these questions in a forum for LabVIEW users the opinions given are going to be somewhat slanted towards the general like of LabVIEW. I've been working with LabVIEW for a long time, ever since 2.something on a Mac. I've written numerous large-scale applications as well as "mundane" instrument drivers. As you've noted you're experienced with LabVIEW, so you know some of its strengths and weaknesses.
To address your specific questions:
(1) Yes, that has always been a limitation in LabVIEW, but I don't believe it is an overriding one to choose C over LabVIEW. Putnam provided one workaround for the search and replace of VIs. Once you've programmed in LabVIEW long enough you get used to doing it this way. Is it clumsy? Yes. As for the re-use of code structures, that's not entirely true. You can create a "template" VI (a regular VI, not a .vit) that contains the code you want to re-use and place in your palette with the "Merge VI" option set. That way you can select it from your functions palette, plop it down on your diagram, and you get the "template" VI's diagram placed right into your new VI.
(2) This is not something that is specific to LabVIEW, as this exists with any programming language. It's not the language that limits you here, it's how you've designed your code. In a language like C++ you would go with classes. You can do the same thing in LabVIEW. IVI is another option (though not preferred by me).
(3) As Putnam mentioned, you should be using the event structure.
Other thoughts:
The biggest strength I see with LabVIEW is that each VI is a miniature program, which allows development and debugging of functions a snap. With a language like C you have to write another program to call that function in order to debug it. The biggest weakness? I would say user interface. Yes, even with the event structure. Don't get me wrong, the event structure has vastly improved the way user interfaces and event handling in general are done with LabVIEW, but it simply doesn't hold muster to a program written in C or VB. ActiveX anyone? LabVIEW still doesn't do ActiveX properly in terms of actually getting the controls to work. Programming ActiveX controls is just plain aggravating what with all the property nodes taking up so much diagram space.
It certainly makes sense to use the best tools available to you to get the job done. In my recent projects I had to write software to run automated tests on some products my company made. The test modules were written in LabVIEW. The tests executive was a proprietary engine driven by a SQL Server database. I had to write a "wrapper" DLL that interfaced between the LabVIEW code and the executive since the executive hadn't been designed to call LabVIEW DLLs directly. This allowed us to use LabVIEW as the preferred language for developing the test modules and let the guys who were fiddling with the test executive do their bit. Of course, TestStand's premise is basically that.

Maxdb - programming language interface

Which is the best programming language to interface with MAXDB database ?
Is there any framework that provides easy integration of MaxDB with the programming language ?

Ok, I admit, I'm not a professional java developer but....
STRUTS is a general web application development framework.
VELOCITY is a language for using templates to use java objects.
RUBY ON RAILS is also a language/framework for creating web applications.
None of them is specifically a database integration framework.
If you want an example for a application framework that works seamless with MaxDB and all other major databases - go for SAP NetWeaver
It has a lot to offer, a huge user/developer base, professional support, really is mission-critical-proof and you can download the developer version here in SDN as well.
> I am a beginner in using maxdb database. And I want some proper guidance in using Java for interfacing with the database.

Ok, the documentation may be a bit more extensive - but it already covers quite enough to get started.
E.g. [Example: HelloMaxDB|http://maxdb.sap.com/doc/7_7/46/7bb199e97150d1e10000000a155369/content.htm].
Make sure to check the [Java Manual|http://maxdb.sap.com/doc/7_7/46/7bb193e97150d1e10000000a155369/content.htm].
> hence, requested for baby steps to build an java application.
You've got the 'baby steps' right there.
But there's not going to be anybody taking them for you - programming is not following screenshots ...
So, have fun!

Executing tiny programming language compiled byte code with the JVM

Hello,
For a project, I am developing a simple programming language, with a syntax not unlike Pascal, which compiles to Java Byte Code. Currently I execute the compiled byte code using my own interpreter. This works OK, but what I'd like to do now is to execute the compiled byte code using the actual existing JVM. The compiled byte code resides in a text file upon compilation of a sample program written in my tiny programming language. Does anyone know how I may start to go about this? Thanks in advance.
adam

The only way of getting a standard Java virtual machine to execute your java byte code, is to wrap it up into a completely valid java class file.
Any constants you use, must be put into the classes constant pool.
Any local variables will have to go into the local variable table of the method which uses them... etc, etc.
Something like ASM, would let you dynamically create a Java class file.

Multiple vis with the same iak filedpoint

Hello everybody,
I have created 3 vis with the same iak file and the intention to run them on the same Fielpoint module each one individually. My FP is connected with an RS-232 on the COM of the PC. Up until now with my current knoweledge these vis cannot run simultaneously. However, I accidentally run the two of them and they seemed to be working fine. I even tried to run the 3rd one and still there was no problem. These vis share the same iak, the same FP module and two of them even read from the same channels.
Does anyone know how this is possible? I have tried it when I was new to Labview and it did not work. Is there some kind of option that I have activated without knowing it?
Thanks for the help
Evdo.

HI!
   You have created 3 top level VIs, right? And now you would like to run they toghether in a FiledPoint, if I understood correctly.
   It is possible, except if they access different resources, I suppose. For example, it is not optimal that 2 VI access the same COM port (this is what you'd like to do, isn't it?). Maybe, that's why they don't work together.
   I think you should re-engineer your code to separate task into different VI: for example, you program to have only one subVI that open COM port, and the other subVIs, which formerly communicated directly to PC, send someway data to this subVI, and this subVI handle messages....
   What kinfd of FieldPoint module are you using? This can help..... Iak file should not matter, upon what you stated.
   have a nice day!

How do you use the bluetooth VIs with a Microsoft Bluetooth Driver?

How do you use the LabVIEW Bluetooth VIs with the Microsoft Bluetooth driver? I have been trying with no such luck.
   I want to use 2 computers to talk to each other using the bluetooth VIs.  Eventually, I think we would like a PDA/phone to talk to a custom built electronics board with Bluetooth. But for now, I would just like 2 computers to talk and then eventually talk to our own device.
One is a desktop w/ the Belkin F8T012 USB adapter. It installs fine with the Belkin driver (but I know I need to use the Microsoft Driver in order to use the LabVIEW VIs, but I have tried to get Windows to install its own but it says it is a BCM92045DG-Flash. It says it cannot install it because it cannot find the necessary hardware. I thought this USB adapter was on the approved Bluetooth devices list? What else should I try? Another Bluetooth USB adapter?
The other computer is a Dell Latitude 820. It has a built in Bluetooth module which I believe is the Dell 350 Bluetooth Module. On this machine I have been able to setup a COM port with a bluetooth device (blood glucose meter). It came with a serial port interface which we modifed to go through a bluetooth interface. It comes up as COM40. We have been able to communicate to it using their program originally designed to talk through a serial port. But we would like to use the Bluetooth VIs in LabVIEW. I can't even use the Discover VI.  Perhaps it is not using the Microsoft Driver as well. Do I just uninstall the driver and then try to have Windows install its own driver? Do you have any other recommendations?
Thanks,
Javi

Hi Javi,
This sounds like an issue with Windows and your specific Bluetooth devices. As you mentioned, the LV Bluetooth VI's do require that the devices use the Windows drivers. Take a look at this link for specific requirements for using Bluetooth with LabVIEW. Also, you can take a look at our Developer Zone tutorial on designing Bluetooth applications a found here. Regarding your device drivers, sometimes it is as easy as uninstalling the driver and then letting Windows discover the device and fine its own driver. You could check out the Microsoft Knowledgebase for more information. Thanks and have a great day!

Developer: How can I let people open files with my program?

Hello Everyone,
I just finished my program for the Mac, and decided to make it an application.
I used Platypus to make my program into an application. Unfortunately when I try to open a file with my program (control + click on file + open with -> other), my application is grayed out and I can't select it. I see it there along with the other applications but I can't select it like I can Mail or TextEdit.
I read somewhere I had to use XCode to let people open files with my program but I have never used XCode and I have no idea how to do that. Any help would be appreciated.
Thanks,
Nick

You've posted in the wrong forum. This is the OS X Leopard Installation and Setup forum. You need to post your problem in the Developers forum. Also, since Platypus is not an Apple product, you should visit it's developers forum for assistance. The Apple Discussions is intended to assist users with problems and questions about Apple products only.
To use XCode Tools you need to install it from the Optional Installs folder on your OS X Installer Disc One. It comes with documentation. More assistance can be found at developer.apple.com.

Java programming language main method question?

Hello everyone I am quite new to the Java programming language and I have a question here concerning my main method. As you can see I am calling 4 others methods with my main method. What does the null mean after I call the method? I really don't understand is significance, what else could go there besides null?
public static void main(String[] args)
          int cansPerPack = 6;
          System.out.println(cansPerPack);
          int cansPerCrate = 4* cansPerPack;
          System.out.println(cansPerCrate);
          have_fun(null);
          user_input(null);
          more_java(null);
          string_work(null);

..As you can see I am calling 4 others methods with my main method. 'Your' main method? Your questions indicate that you did not write the code, who did?
..What does the null mean after I call the method?.. 'null' is being passed as an argument to the method, so there is no 'after the method' about it.
..I really don't understand is significance, what else could go there besides null? That would depend on the method signatures that are not shown in the code snippet posted. This is one of many reasons that I recommend people to post an SSCCE *(<- link).*
BTW - method names like have_fun() do not follow the common nomenclature, and are not good code for a newbie to study. The code should be put to the pointy end of your sword.

Choose a programming language

I want a program that can
analyse http://www.youtube.com/browse?s=mr&t=&l=&e=en_US&p=* (*=1-5) every 10 minutes
then pick out the link that start with http://www.youtube.com/watch?v=
export their related information and their links to a form that I want
sort them as their youtube added time
and it can run on my webpage
so what programming language should I choose to write this program?

Your program consists of two parts, to query the site in a given interval and to display the videos/information on your website. I think PHP would suite best for displaying the videos on your page, but then, if you have a python/ruby powered website then use the one you make your website with. For the query part I would use python and write a small script that gets triggered via a cron job in the interval you like. Instead of parsing the contents of the page itself I would use the RSS feed provided by the youtube page, there's a python module named "feedparser" with which you can easily access the feed contents and extract the related information (shouldn't be more than maybe 50 lines of code), write it to a database (sqlite), in the form that you like, and retrieve the contents via your PHP script on your webpage. Or completely skip the time interval query part and just check for new videos when someone visits your website .

Attn: Sun. Can we distribute the JRE with a program we write?

I'm trying to find out whether it's legal to distribute the JRE with a program I write. If you look at the license agreement when you download the JRE, first it has the regular license agreement, which says that you can't. But then it has the "supplemental" license agreement (and it says that this "modifies" the regular license agreement). In section 2 of the supplemental license agreement, it quite clearly states that you can as long as you don't modify it and you include some little messages in your documentation.
So I'm hoping to get an answer from someone who actually works for Sun. It seems pretty clear to me that we ARE allowed to distribute the JRE with a program, but people keep sending me emails when I tell them about it - saying things like "You can't program in Java because you can't distribute it."
What I want to do is have an installation program that installs my game and then installs Java (with Sun's JRE installer - this is included ONLY so that it can run my game, as stated in the supplemental license agreement). I should also mention that I do actually intend to SELL this program, so if that's a problem, please say so. Anyways, could someone from Sun tell me whether this is allowed or not? I don't want to break the law.
- Steve Fletcher

The JRE includes a readme file that explicitly states that distribution is permissible, given certain conditions. In particular, look at the 1st paragraph below:
Reproduced here:
README
Java(TM) 2 Runtime Environment, Standard Edition
Version 1.4.1
The Java(TM) 2 Runtime Environment is intended for software developers
and vendors to redistribute with their applications.
The Java 2 Runtime Environment contains the Java virtual machine,
runtime class libraries, and Java application launcher that are
necessary to run programs written in the Java programming language.
It is not a development environment and does not contain development
tools such as compilers or debuggers. For development tools, see the
Java 2 SDK, Standard Edition.
=======================================================================
Deploying Applications with the Java 2 Runtime Environment
=======================================================================
When you deploy an application written in the Java programming
language, your software bundle will probably consist of the following
parts:
Your own class, resource, and data files.
A runtime environment.
An installation procedure or program.
You already have the first part, of course. The remainder of this
document covers the other two parts. See also the Notes for Developers
page on the Java Software website:
http://java.sun.com/j2se/1.4.1/runtime.html
Runtime Environment
To run your application, a user needs the Java 2 Runtime Environment,
which is freely available from Sun for application developers to
redistribute.
The final step in the deployment process occurs when the software is
installed on individual user system. Installation consists of copying
software onto the user's system, then configuring the user's system
to support that software. You should ensure that your installation
procedure does not overwrite existing JRE installations, as they may
be required by other applications.
=======================================================================
Redistribution of the Java 2 Runtime Environment
=======================================================================
The term "vendors" used here refers to licensees, developers, and
independent software vendors (ISVs) who license and distribute the
Java 2 Runtime Environment with their programs.
Vendors must follow the terms of the Java 2 Runtime Environment Binary
Code License agreement.
Required vs. Optional Files
The files that make up the Java 2 Runtime Environment are divided into
two categories: required and optional. Optional files may be excluded
from redistributions of the Java 2 Runtime Environment at the
licensee's discretion.
The following section contains a list of the files and directories that
may optionally be omitted from redistributions with the Java 2 Runtime
Environment. All files not in these lists of optional files must be
included in redistributions of the runtime environment.
Optional Files and Directories
The following files may be optionally excluded from redistributions:
lib/charsets.jar
Character conversion classes
jre/lib/ext/
sunjce_provider.jar - the SunJCE provider for Java
Cryptography APIs
localedata.jar - contains many of the resources
needed for non US English locales
ldapsec.jar - contains security features supported
by the LDAP service provider
dnsns.jar - for the InetAddress wrapper of JNDI DNS provider
bin/rmid
Java RMI Activation System Daemon
bin/rmiregistry
Java Remote Object Registry
bin/tnameserv
Java IDL Name Server
bin/keytool
Key and Certificate Management Tool
bin/kinit and jre/bin/kinit
Used to obtain and cache Kerberos ticket-granting tickets
bin/klist and jre/bin/klist
Kerberos display entries in credentials cache and keytab
bin/ktab and jre/bin/ktab
Kerberos key table manager
bin/policytool
Policy File Creation and Management Tool
bin/orbd
Object Request Broker Daemon
bin/servertool
Java IDL Server Tool
In addition, the Java Web Start product may be excluded from
redistributions. Depending on the platform, the Java Web Start
product is contained in a file named as follows. The actual
product version number would replace the <version number> notation.
javaws-<version number>-solaris-sparc-i.zip
javaws-<version number>-solaris-i586-i.zip
javaws-<version number>-linux-i586-i.zip
javaws-<version number>-windows-i586-i.exe
Redistribution of Java 2 SDK Files
The limited set of files from the SDK listed below may be included in
vendor redistributions of the Java 2 Runtime Environment. All paths
are relative to the top-level directory of the SDK.
- jre/lib/cmm/PYCC.pf
Color profile. This file is required only if one wishes to
convert between the PYCC color space and another color space.
- All .ttf font files in the jre/lib/fonts directory. Note that the
LucidaSansRegular.ttf font is already contained in the Java 2
Runtime Environment, so there is no need to bring that file over
from the SDK.
- jre/lib/audio/soundbank.gm
This MIDI soundbank is present in the Java 2 SDK, but it has
been removed from the Java 2 Runtime Environment in order to
reduce the size of the Runtime Environment's download bundle.
However, a soundbank file is necessary for MIDI playback, and
therefore the SDK's soundbank.gm file may be included in
redistributions of the Runtime Environment at the vendor's
discretion. Several versions of enhanced MIDI soundbanks are
available from the Java Sound web site:
http://java.sun.com/products/java-media/sound/
These alternative soundbanks may be included in redistributions
of the Java 2 Runtime Environment.
- The javac bytecode compiler, consisting of the following files:
bin/javac [Solaris(TM) Operating Environment
and Linux]
bin/sparcv9/javac [Solaris Operating Environment
(SPARC(TM) Platform Edition)]
bin/javac.exe [Microsoft Windows]
lib/tools.jar [All platforms]
- jre\bin\server\
On Microsoft Windows platforms, the Java 2 SDK includes both
the Java HotSpot Server VM and Java HotSpot Client VM. However,
the Java 2 Runtime Environment for Microsoft Windows platforms
includes only the Java HotSpot Client VM. Those wishing to use
the Java HotSpot Server VM with the Java 2 Runtime Environment
may copy the SDK's jre\bin\server folder to a bin\server
directory in the Java Runtime Environment. Software vendors may
redistribute the Java HotSpot Server VM with their
redistributions of the Java Runtime Environment.
Unlimited Strength Java Cryptography Extension
Due to import control restrictions for some countries, the Java
Cryptography Extension (JCE) policy files shipped with the Java 2 SDK,
Standard Edition and the Java 2 Runtime Environment allow strong but
limited cryptography to be used. These files are located at:
<java-home>/lib/security/local_policy.jar
<java-home>lib/security/US_export_policy.jar
where <java-home> is the jre directory of the Java 2 SDK or the
top-level directory of the Java 2 Runtime Environment.
An unlimited strength version of these files indicating no restrictions
on cryptographic strengths is available on the Java 2 SDK web site for
those living in eligible countries. Those living in eligible countries
may download the unlimited strength version and replace the strong
cryptography jar files with the unlimited strength files.
Endorsed Standards Override Mechanism
An endorsed standard is a Java API defined through a standards
process other than the Java Community Process(SM) (JCP(SM)). Because
endorsed standards are defined outside the JCP, it is anticipated that
such standards will be revised between releases of the Java 2
Platform. In order to take advantage of new revisions to endorsed
standards, developers and software vendors may use the Endorsed
Standards Override Mechanism to provide newer versions of an endorsed
standard than those included in the Java 2 Platform as released by Sun
Microsystems.
For more information on the Endorsed Standards Override Mechanism,
including the list of platform packages that it may be used to
override, see
http://java.sun.com/j2se/1.4.1/docs/guide/standards/
Classes in the packages listed on that web page may be replaced only
by classes implementing a more recent version of the API as defined
by the appropriate standards body.
In addition to the packages listed in the document at the above
URL, which are part of the Java 2 Platform, Standard Edition
(J2SE(TM)) specification, redistributors of Sun's J2SE
Reference Implementation are allowed to override classes whose
sole purpose is to implement the functionality provided by
public APIs defined in these Endorsed Standards packages.
Redistributors may also override classes in the org.w3c.dom.*
packages, or other classes whose sole purpose is to implement
these APIs.

How to create an Oracle DATABASE through Java Programming Language.. ?

How to create an Oracle DATABASE through Java Programming Language.. ?

Oracle database administrators tend to be control freaks, especially in financial institutions where security is paramount.
In general, they will supply you with a database, but require you to supply all the DDL scripts to create tables, indexes, views etc.
So a certain amount of manual installation will always be required.
Typically you would supply the SQL scripts, and a detailled installation document too.

If programming languages were weapons. By Bjorn Tipling

If programming languages were weapons
ABAP is missing! Oh noooo!!
Personally, as an ABAP novice, I see it somewhere between Mathematica and LISP:
A monster that shoots highly effective anti matter rays with the reliability of an AK-47. If you are more old school you can also grab it by the red handle and smash heads of your opponents with the spiked club or throw some elegant samurai OO coding in and slice them to sashimi with the black blade! Expensive like hell, though.
Where do you see ABAP?
Would you like to contribute a picture?

What programming language to learn after ABAP?

Hi All,
Well I am kind of getting bored with ABAP / Workflow ! I was wondering what programming language should I learn to keep myself busy. What I am looking for is something new (it can be a an extn for ABAP/ SAP too) but something really new age. May be something like Mobile Apps for SAP. May be a new language all together. But again since SAP is bread and butter it would be nice if it can be used in someway or another in SAP too
Any ideas?
P.S.: I have 8 years of SAP experience so I am not noob !
Moderator Message - I am un-marking this post as a question.

Well yes I agree that moving to new module is a good career move. But I am not looking to make a career move ! Its something just on the side..
I know webdynpro.. BI I need access to a system ! HANA same thing.. I am not independent in learning..I need some one to set up the system/login/access etc.. and thats not going to happen unless I sign up for a class !
While I write this my previous comment is still under moderation ! So I am gonna copy paste it here :
Thanks Guys !
I am looking for something which I can learn independently ! without having to go after basis guys to download some SDK for me and installing notes for me.. Thats one of the reason learning anything new in SAP is a hassle. I guess BOBJ us out of question for this reason.
While HTML-5 sounds interesting wont I be better off learning Python? I know I can look it up but if you know offhand whats the benefit of HTML-5 and what kind of independent work I can take up for it ? I dont care about money but as long as its interesting I am ok with that !
I do have basic knowledge of C so C++/ Objective C may be a good move .. JAVA I am not sure off as its use has been declining off late (its still number 1 but its market share is going down).

What programming language should i learn first?

Hi, i'm Francis, from Rome. As you can see, i have a MacBook White with Mac OS X 10.5.8.
Yesterday i downloaded *Xcode with iPhone SDK (version 3.1)*. I want to create Mac and iPhone/iPod/iPad applications.
I read that there are several programming languages: Java, Cocoa, Cocoa Touch, C, C++, Objective C, Objective C++, Carbon, Classic, BSD, etc...
What should i begin with? +I think Cocoa, Cocoa Touch, C and Objective C, but i'm not sure!+
Can you help me? Thanks!

Java, C, C++, Objective-C are languages. Cocoa, Cocoa Touch, Carbon, and Classic are what are known as APIs - resources you can use in your programs but not languages in their own right. BSD is short for BSD UNIX, and it's an operating system (that's the foundation for OS X). HTML is a document format more than a language.
What language(s) to learn depends on your objectives or needs. OS X comes with Python, Ruby, PERL, AppleScript, and PHP languages (and JavaScript in the web browser). Current versions also include Java. If you install the OS X development tools, it adds C, C++, and Objective-C along with the XCode development environment.
Each of the languages has it's strengths and weaknesses. From a purely educational standpoint, C is a high-level language that will teach you about low-level programming. Java teaches very strong object-oriented programming.
Objective-C would permit you to develop using the iOS toolkits for iPhone and iPad, and also application programming for OS X.
PERL, Python, and Ruby are all simple to learn scripting languages and very powerful for all sorts of automation tasks, text processing, and CGI scripting.
