An open labview 8.5 application in labview 8.1

hi to all .i made application in labview 8.5 in evaluation version. i have the licsence of labview 8.1. my question is can open my application or vi block digramme in labview 8.5.

Hello,
You have to open yopur application with LabVIEW 8.5, go to file and save for previous version and select LabVIEW 8.0.
This means you need a LabVIEW 8.5 version, I have no idea if the evaluation version of LabVIEW 8.5 can save for previous version
By the way, LabVIEW 8.1 does not exist. Only 8.0, 8.0.1 and 8.20

Find names of all open windows including other applications besides LabView VIs

Hi All, I have researched this subject, i.e., to find names of all open windows including other applications besides LabView VIs, but found no solution. Could someone suggest a solution to this? Thanks.

Hi,
Certainly! The Windows API Function Utilities (32-bit) for LabVIEW includes set of LabVIEW libraries (llb) with VIs that make calls to the Windows Application Programming Interface (API) for managing and controlling windows (minimize, maximize, move, resize, rename, close, and so on) including task list with names of windows application running. The Readme.doc contains information on running these VIs.
Attached below is a zipped file with a VI that list the names of all opened windows.

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.

Control LabVIEW from different application

I made an application that generates user requested amount of outputs and also takes parameters and IO controls from the user. It seems to me LabVIEW is a perfect tool for the user to do the screen layout. My question is once the layout is done, can I programmatically open the vi file and associate any of my outputs to the screen objects (for example an edit box or a channel of a graph etc.) and feed those screen objects with my data at run time? In other words, is there any APIs for LabVIEW so that I can go in to a vi file and interrogate its components’ properties and then getting or feeding values to/from those components during run time? Can it generate events when a user clicked on a button etc..?
Thanks in advance

Solved!
Go to Solution.

If it is just for displaying data in a way that the user can customise, I would reccommend you just stay with what you are familiar with. I mentioned a few posts ago that I know for a fact that you can #include a GUI panel resource into a C++ runtime application.
If you do want to run the viewer in LabVIEW, then unless each user is a skilled LabVIEW developer, you will need to run their uncoded VI through an intermediate or parsing LV application which will act as a bridge. This will need to be written in LabVIEW because a VI is saved in a format native to LabVIEW.
I might be able to make a demo on Monday, but for now an abstract description if anybody else wants a quick crack at it;
You could create an opc server (or another data sharing technique) on your data aquisition application, the LabVIEW bridge application will then be able to pull data in.
The bridge application can dynamically get a list of controls from the user panel, and users will be able to tell the bridge what data to pull from the opc server and where to put it.
There will need to be data sanitising; checking imported data types are suitable for where the user wants to put them.
After finishing any configuration, the bridge app will continue to pull in data changes and drop it into the uncoded User Interface panel using the VI server nodes.
Jian, for now you can read up on LabVIEW introduction courses (link, link), and then search for info on the VI Server

Open LabVIEW 8.0 files in LabVIEW 7.0

Hello,
I have developed an application in LabVIEW 8.0 and built a standalone executable just to realize that I have to deploy it in a Windows NT computer that is not compatible with LV Run Time Engine 8.0 that only supports Windows 2000 and XP. I have tried to open the labView files (*.vi) using LabVIEW 7.0 but it gives me an error. Is there any easy and clean solution to import these files in LV 7.0 in order to build a new excutable and make it compatible with Windows NT?
Regards,
Toni

The only way to convert these files to version 7.0 is to first save them as 7.1 and then open them up in version 7.1 which can then save them as 7.0. If you don't have a copy of 7.0, then if you post the VIs, someone may do the conversion for you. If you have used anything in the program that is not supported in an older version of LabVIEW, you will have to rewrite it. In the long run, it might be simpler to just upgrade the NT computer to something that LabVIEW (and Microsoft) supports.

Open a *.exe application in LABVIEW with system exec function.

Greetings,
I would like to be able to lauch a *.exe application and open a specific file within my labview vi. The trick is to avoid using active X control at all cost. I would like to use the system exec function but I couldn't quite get it to work.
Let's assume that I would like to lauch wordpad.exe from my local drive. What are the params I need to pass? Thanks.

You have to type in the command line of the System exec vi the name of the executable and eventually its path.
Look at the attached vi that launches Wordpad as you asked.

When I try to open some of my vi's, LabVIEW quits abruptly.

When I try to open some of my vi's, LabVIEW quits abruptly. Has anyone seen this before? It doesn't happen with all my vi's . It could be related to updating Red Hat Enterprise Linux 4 recently.

What do your VIs have in
common that crash? They wouldn’t be
calling external code by chance would they (i.e. a call library function
node)? LabVIEW loads DLLs (or shared
objects in Linux) just as soon as the VI which calls it is loaded in memory
(unless you’re using some new fancy features).
If some of these code modules don’t load right the application could be
killed right away.
Have you seen this behavior before? If not, I gather you might be on to something
– the update to your OS could be to blame.
That distribution should work – was there anything else that you may
have done during the switch?

Open an old VI version on LabVIEW 8.2

How can I do to open some old VI (made on LabVIEW 6i) at LabVIEW 8.2?

Hi Morim,
Any VI written in LabVIEW 6 or later should convert to 8.5 when you open it. There may be some change in the functionality of the code, I would suggest reading through the 8.5 upgrade manual and going to page 38 where changes in functionality are outlined.
I hope this answers your question.

Problems installing FP v4.1 with LabVIEW v6.1 application

We have a LabVIEW v6.1 application that interfaces to a FieldPoint FP-1000 Network Module for its I/O. We have been distributing it to customers for about 18 months with the FieldPoint v4.0.1 driver - no problems other than some difficulty getting the Watchdog Timer setup properly via MAX.
The latest purchase of FieldPoint hardware came with FieldPoint v4.1 driver. There are three issues that have arisen with the advent of FP v4.1.
1.) There occurs several (identical) warning messages during the FP v4.1 installation on Windows XP SP2 (the exact number depends on the selection of features to install). The message is "Error 1931" and it says that Windows stopped the installer from updating the stdole2.tlb file. It suggests that we update the OS, which has been done, but the messages continue.
Question: is it critical that the stdole2.tlb in the FP v4.1 distribution be installed, or is this an error with no consequences?
2.) When installing FP v4.1, we select LabVIEW v6.1 support, but disable the Real-Time v6.1 Support and the Examples. We also disable the LabVIEW v7.0 and v7.1 Support and the LabWindows/CVI Support. We keep the Documentation and MAX features. We have gone through the install/uninstall cycle several times and each time when uninstalling the list of features includes LabVIEW v7.0 Support - not v6.1.
Question: does this indicate that the installer is erroneously installing v7.0 support and omitting the selected v6.1 Support? Or is this just an error in what is displayed by the uninstaller?
3.) After FP v4.1 is installed (with LabVIEW v6.1 Support selected) our LabVIEW v6.1 application runs but fails to communicate with the FP-1000 Network Module. Upon quiting the application, there is an error message stating that the FP.Open.vi failed to run because the FieldPoint Server .dll was not found (no filename for the server- just ".dll").
Question: Is this an issue of the installer not putting the proper FP Server .dll file on the computer (see question 2) or is this a matter of compatibility (do I need to install FP v4.1 on the development computer and remake my application)? Something is wrong here, FP v4.1 doesn't support a LabVIEW v6.1 application that runs fine under FP v4.0.1. Do I need to install the LabVIEW v7.x Support in addition to the v6.1 Support?

Hi lkj,
There has been few reported problem with installing FP4.1 in LabView 6.1, but none of them are similar to what you are experiencing. According to the 4.1 driver documentation certain vis from this driver version cannot be installed and used in LabView 6.1. What I would suggest is to uninstall the current driver and revert back to the ver. 4.0.1 since we know for sure it works in the LabView 6.1 environment. If you you'd like to use the 4.1 driver, then if would suggest upgrading to LabView 7.0 or 7.1.

Natasa

Hi Guddan,
I created a RFC having a query which is taking a long time to execute. So i want to close RFC connection with portals which is via java connector(JCO) before that query and open the connction again after that query.
I guess i will need to understand your requirement a little more in detail, as i understand you have an RFC which has a query within to fetch some data and is taking a long time to do so. In the meantime you don't want to keep the connection open?
My question would be, Is the role of this RFC to only execute the query and fetch the data or does it do something else?
If it does other things and these are independent of the query execution, then you can span a parallel call within the RFC to execute the query and in the meantime the RFC does the other things (or vice versa) hence reducing the overall time taken.
If the sole purpose of this RFC is to execute the query, then you will not be able(i mean to say there is no simple and direct way of doing this) to close the connection after the Query is started and re-establish the connection after its execution, for a simple reason that - how will you know if the query has completed it's execution, so that you can establish the connection back.
Alternate solutions, make this a two way asynchronous call, 1) You invoke the RFC asynchronously and close the connection, the RFC in turn will execute the query and transfer the data to JCO via another RFC call.
If this needs to be a synchronous call, then you will need to optimize the query to its best.

Chen

Advantages of using labview in embedded application when compared to c ?

Hello all,
I am looking to develop embedded application with help of labview programming
Started with Lm3s8962 evaluation board.
So i would like to know
1 Advantages of using labview in embedded application when compared to c ?
2 Can we deploy the code in any kind of controller by writting drivers for it ?

hello, the LM3S8962 microcontroller is a good sispositivos for developing applications of medium complexity, according to your questions:
1. if you work applications with embedded systems will save labview time in prototyping, we know that if you work with a company specific microcontroller, you must learn the language with which you are working Asm, Basic, C, then if you change hardware again start adapting your code in the libraries of the new compiler. Labview does not happen.
2. Labview only works with some microcontroller manufacturers and specific models.

Standalone application without labview ?

Hi
I am trying to build an .exe file using application builder in LabVIEW 7.0. Is it possible to build an application without labview dependency ? In short, I want something like an .exe file which will run on systems without labview. I know visual basic has this facility. Please let me know.
Thanks
Sridhar.

?<br><br>Sridhar.
You are not right. It is possible. With LV 7.0 and previous versions (I
don't know if this still works for 7.1), the executable will run correctly
if lvrt.dll and the other support files are in the same directory. So you
could, for example, put your executable on a thumb drive. Copy all files
and folders in the C:\Program Files\National Instruments\shared\LabVIEW
Run-Time\7.0 directory to the thumb drive as well. Then your supervisor
could just run the program from the thumb drive without copying anything to
his computer. Or, if you want the drive back, he could copy the entire
contents to his drive without using an installer.
But this begs the question, if your supervisor is evaluating executables you
are creating in LabVIEW, what's the problem with installing LV Run-Time on
his computer?

Looking for book "Internet Applications in LabVIEW"

This book must either be a really good one or they didn't print very many. I have been searching for months for an used copy, and the only one available is by some book seller who wants $200 for it. I have been in contact with Jeffrey Travis (the author) through his site, and he does NOT plan on updating it to a newer edition. In case anyone wants to know, a new 3rd edition of his "LabVIEW for Everyone" is coming out soon (which I have already pre-ordered on Amazon). About a week ago I had actually ordered an used copy of "Internet Applications in LabVIEW" when another copy (much more reasonably priced) showed up on Amazon. The description said the CD was missing, so I emailed Mr. Travis about buying a copy of the CD, and they didn't have a single copy of it. Well, a few days later an Amazon email told me the order for the book got cancelled because it was out of stock. Hmmm. I guess I'll keep watching. If you have a copy would you like to sell it? Is there any book that anyone knows of that covers Internet/network-related info like this book? I have Gary Johnson's "LabVIEW Graphical Programming" 3rd edition and also have the new edition of that book pre-ordered on Amazon.
Thanks,
Brad

For $200 I'd be tempted to sell my copy. I even have the CD.
It's too bad that Jeffrey Travis will not be updated the book but there's probably not a lot of money to be made. The book was excellent for it's day but an awful lot of the content has been made obsolete with the release of LabVIEW 6 and remote panels. I think the book was written for LabVIEW 5.0. About the only thing that I might refer to the book now would be some of the Internet Toolkit examples. If you have some specific questions about LabVIEW and Internet applications, go ahead and post them.

Is it possible to invoke other software applications in labview?

Is it possible to invoke other software applications in labview? I would like to upload my files processed in Labview to my web based database. I have no basis of FTP and SQL. Providing that I have no Internet Database Toolkit installed in my computer. So, is it possible to "call" the software in Labview, just like calling a function or sub VI?

Hello kaykeat,
It is definitely possible to call other applications inside LabVIEW. Please see the links below for more help on the most common ways to call external programs.
If the code is a shared library:

When calling an activeX method:

Using .NET in LabVIEW:
