Using aliases in LabVIEW

Using visaconf, I have set aliases for each of my devices. How can I use the aliases in VISA finder in a block diagram ? I want to avoid using strings like GPIB0::12::INSTR etc. if possible (plus avoid mistakes).

If by VISA finder, you mean the VISA Find Resource function, you can specify the search mode to return the aliases instead of the canonical name. Try a value of 4. A front panel VISA Resource Name control should automatically display an alieas if it exists.

I would like to convert a matlab file into a .dll and use it in LabVIEW. However, when I run the .dll in LabVIEW I get an error stating "... Procedure not found". What could this be? Can anyone help me...

I wish to convert my Matlab files into .dll's so that I can use them in LabVIEW. I am using 'mcc' and 'mbuild' of Matlab to convert my .m files into .c and .dll.
When I try to run the .dll's in LabVIEW, I get an error message in a modal window stating some required .dll or procedure is not found.
How should I resolve this issue. Should I add any other Matlab .dll's in course of making my .dll?
Please help in solving this issue... Thankyou very much.

Can we use Aliases instead of member name in Calc Manager

We migrated business rules to Calc Manager. After migration Calc Managers are not getting validated (stating the member is missing in the database). Later found out that in the script it has alias name instead of member name which was causing this error.
example
Member name = C001
Alias = Texas
in the script it is mentioned Texas = 5; (this statement throws an error while validating, stating Texas is not present in the outline, even though Texas is present in the Alias table as an alias for C001).
Once I modify the script to C001 = 5; it gets validated without any issue.
Does this mean in Calc Manager we cannot use Aliases unlike business rules and Calc Scripts?
Please advice.

The 'Defects Fixed' section of the release notes for 11.1.2 includes...
"Calculation scripts validate inconsistently in Essbase and Calculation Manager (8800397)."
...which is pretty broad!
Can you run the rules OK? If so, I'd just ignore the Calculation Manager validation message.

How to use dll in Labview ?

I compile this code to dll file with VC++2010 filename is test_dll.dll .
#include "stdafx.h"
#include <iostream>
#include <Windows.h>
using namespace std;
int main(int a){
cout << "Test dll...............\n";
return a;
After that, I put Call Library Function node in editor and double click Call Library Function node. I browse test_dll.dll into Library name or path and set function prototype to int32_t main(int32_t a); but it show error Call Library Function Node 'test_dll.dll:main':function not found in libraly. How to use dll in Labview ? And I have more question is what is differrent from Tools -> Import -> Shared Library(.dll) and use Call Library Function node.
Solved!

The issue you are having is that LabVIEW is not capable of using C++ DLLs directly. It only handles C DLLs. This does not mean that if you you cannot use the DLL if it's compiled with the C++ compiler as opposed to the C compiler. Rather, it means that you must take extra steps in order to use it from LabVIEW. The primary issue is that of name mangling or adornment. This is discussed here: http://zone.ni.com/devzone/cda/tut/p/id/4877. Basically you need to prepend extern "C" in front of your prototypes in your header files. I would also suggest reviewing this article: https://decibel.ni.com/content/docs/DOC-14564.

I couldn't find an Instrument Driver for the 3932 crate controler. There is a driver for the 3988: http://zone.ni.com/idnet97.nsf/9b2b33e1993d877786256436006ec498/045f8392cc4d1b01862568ab005fbb49?OpenDocument
If you look at the driver it isn't too complex. Well ... actaully there are certain differences when using the 3988 GPIB controller that the driver takes care of that relate to correctly passing commands (FAN).
If the 3922 controller is similar then maybe you can use the 3988 driver and modify it to meet your needs. I'm not familar with the 2915 Kinetic system so I'm not sure what would be easier.
If you have a GPIB board, then you could try using the 3988 driver with your 3922 controller and see if you can modify the driver to get things to work.
I
've only used the 3988 and that was quite three years ago but it might be worth a try.

I find it annoying that you can't use aliases in where statements

I find it annoying that you can't use aliases in where
statements
for example:
SELECT TOP 1
CAST(amount
/ ( CASE WHEN ISNULL(rate, 0) <> 0 THEN rate
ELSE 1
END ) AS NUMERIC(10, 2)) AS num
FROM table
WHERE num > 1
ORDER BY num
Are there any workarounds?

> I find it annoying that you can't use aliases in where

This isn't really (or... "at all") a CF question. You're
better off asking
this sort of thing on a SQL Server forum.
You could use a derived table, I guess:
select top 1 num
from (
SELECT
CAST(amount
/ ( CASE WHEN ISNULL(rate, 0) <> 0 THEN
rate
ELSE 1
END ) AS NUMERIC(10, 2)) AS num
FROM table
where num > 1
order by num
(that might not preserve the intent of you SQL (sorry: it's
late, I'm
tired), but you get the idea.

Hi!!!I need your help!! Does anyone know if there is any Modbus lib or Modbus driver to use this en Labview BUT in LINUX?

I am using Labview to comunicate with ADAM modules, but I want to comunicate with them using Modbus protocol. I don´t want to use "ADAM protocol" ASCII comands that the modules can understand.
So I need a Modbus driver or Modbus libraries. The PROBLEM is that I am using LINUX!!!!!!!!!!!!!!!!
I am looking forward to your answer!!

Ignition Switch to use in a Labview panel?

Has anybody programed vehicle ignition switch to use in a Labview panel to interface to a simulator?

Chris,
I don't have experience in designing such systems, but here is one document that I think will help you in your design.

I was able to find few other articles when I searched on Google for "ignition switch" and labview.

Does anyone know how to use ELVIS in Labview to get current and voltage measurements?

Trying to use ELVIS in Labview to get measurements with a NI myDAQ.

I have changed from using the ELVISmx driver as I was unable to call on the digital multimeter of the myDAQ twice, I have set up a VI using the DAQ assistant with the myDAQ, I am using the AI0 port for a voltage reading and using the DMM for my current reading, the circuit is working as I am measuring the voltage on a resistor after the ammeter but I am unable to get a current reading in order for it to work. If I have something wired wrong please let me know, thank you. My circuit is a 12VAC power supply, going through a potentiometer to drop the voltage to 8VAC, which passes through a resistor, ammeter is in series after this and attached to another resistor to complete my loop, the AI0 for my volt meter is connected across the second resistor, I have the proper voltage reading when I run the VI, but am unable to get a current input. Thanks for the help.

Why are my LabView Dialog Boxes no longer modal when using the Example LabVIEW Operator Interfaces?

Hello,
I have a step in my sequence that pops up a modal LabVIEW dialog box. My LabVIEW vi uses the TestStand - Start Modal Dialog.vi and TestStand - Stop Modal Dialog.vi as described in the example and it works as advertised when I'm using the TestStand Development environment however when I use the sample Operator Interfaces distributed with TestStand the Dialog boxes lose focus. I have the VI Properties->Window Appearance set to Dialog and have followed all of the instructions I could find for making a dialog modal. I've also reviewed all the documentation I could get my hands on including previous posts on this board and didn't see anything obvious.
Does anyone have any suggestions as to what I may be missing? Has anyone else experienced this problem and come up with the solution?
I am using LabVIEW 8.0 along with TestStand 3.5.
Thanks,
RG

Hi RG,
Running the example modal dialog in the teststand3.5 examples folder and using labVIEW8.0, I notice that when the Dialog is displayed its not active, but it is modal to the OI. Clicking on the Dialog panel makes it active. If you try to click on the OI panel behind, you can not. Is this what you are seeing?
I am using the Full labVIEW IO as supplied with TestStand and the example VI in the modal dialog folder is as supplied.
The LabVIEW Adapter is still configured to use the active labVIEW developement environment.
If I run the same example, only this time using LabVIEW7.1, the Dialog panel is active.
There is a patch to take it to labVIEW8.01, at this moment in time I am not sure what the update fixes.
There does seem to be a problem with TestStand3.5 (engine) and LabVIEW 8.0.

Executing a shell command within vi using aliases

The behavior of the ksh ENV environment variable has been changed in Solaris 10 and I assume it is related to the reason why I can no longer use aliases when using the "bang" (!) command execution in vi. For a very simple example, if ll were an alias for ls -lFbo entering this in vi:
:!llwould produce the expected "ls -l" listing of the current directory in previous Solaris versions. Why does this not work in Solaris 10 and is there an alternate way to accomplish the same thing?

I don't know exactly but the code written below is working fine try the same with your code .Even with your code instead running the code with
" ./<filename> ",if you execute it with "sh <filename>" command without changing the mode of the file it is executing properly.
import java.io.*;
import java.util.*;
public class ScriptBuilder
public ScriptBuilder()
public void writeScript() throws java.io.IOException
FileWriter writer = new FileWriter(new File("test_script"));
writer.write("#! /bin/sh\n");
writer.write("ll>/home/faiyaz/javaprac/checkll");
writer.flush();
writer.close();
Runtime rt= Runtime.getRuntime();
rt.exec("chmod 777 test_script");
rt.exec("./test_script");
} public static void main (String[] args)throws java.io.IOException
ScriptBuilder sb = new ScriptBuilder();
sb.writeScript();

Excel add-in Use Aliases default

It appears that the default setting is Use Aliases. Is there a way to have the default "unchecked" globally?Harold

In the version I have on my laptop (6.5.1) the add-in uses the settings of the last used sheet for all future sheets - which means if you turn aliases on or off, it should retain those settings for future sheets you create.There were issues in some versions/patches of Essbase where the add-in did not reatain settings when creating new sheets, or did not save settings for saved templates. What version/patch of the add-in are you using?Regards,Jade-----------------------------------Jade ColeSenior Business Intelligence ConsultantClarity [email protected]

Using aliases for indicators, controls, procedures and calculated channels

Hello,
I noticed that aliases do not show up in the workspace for indicators and controls, and in the system explorer for procedures and calculated channels. Is there a way for them to show up? I need to use aliases because I would like my system definition to control multiple test systems (which have different CAN signal names). Otherwise my system definition would break whenever I switch to a different CAN database. I thought the inability to address aliases was limited to the right click configurable controls add on, but it looks like VeriStand natively cannot address them in the areas that I'd like as well. Any recommendations would be welcome.
Thanks.
Solved!
Go to Solution.

You are correct that you cannot use Aliases within a System Definition file for mapping purposes. This is an area that we hope to improve in the future. The initial design of aliases was to serve as a public interface for the Workspace, stimulus profiles, and so on. However, it is certainly a valid use case to want to use them as an interface within a System Definition.
One possible workaround would be to create a set of User Channels that act as your public interface in your System Definition. Always use your User Channels in all procedures, calculated channels, and so on. Then map your CAN channels to these User Channels. Whenever you update your CAN database, you only need to remap the new CAN channels to the appropriate User Channel. You could also automate this activity by importing a tab-delimited file in the Mappings page. The one downside here is that your target will take a little extra time to process these mappings.

Problem of security using ADO from Labview to connect to Access 2000 Data Base

I have a problem using ADO from Labview to connect to Access 2000 Data Base.
First I open a ADO_DB_Engine and create a Workspace as an ODBCDirect. After I execute the open_data_base using the workspace. Here you can specify the parameter connect with /type of connection / user / password.
The problem is the following:
Although you configure a password for the Administrator user in Access, you can read/writte to data base from Labview using ADO without any security and without putting the user and password in the parameter connect. I need to access with security to data base using users and permissions but it seems that the parameter connect does not operate.
I attach
you a example of the vis and database. Remember create a ODBC connect with BD3.mdb
Thanks a lot

Hi Kahn,
If you use ADODB_connection -> Connection.Open and set in connection string :
"Provider=Microsoft.Jet.OLEDB.4.0; Jet OLEDBystem Database=c:\.....\Protegida5.mdw; Password=pepe;user ID=jose; Data Source:c:\......\BD5.mdb";
and after connection.execute ->
INSERT INTO tabla1 VALUES (5,'XXX'
you will be able to access to the database with security using the provider=Microsoft.Jet.OLEDB.4.0. With this provider you have to use the path and the name of the database file c:\.....\mdb file. From this way the problem is solved. (SEE SAMPLE_ADO_W2_JET.VI).
BD5.mdb have the following administrator user: user:jose / passwordepe (Protegida5.mdw)
The problem is when you want to
use ODBC and DSN. The name of this ODBC Provider is MSDASQL;. If you use this type of connection you can not enter to the database I attach you.
This database has a new administrator owner. I deleted the default administrator. If you support the default administrator you can connect to database by ODBC / DSN but the security disappear because you can always enter to database with any password, user o PC.
FINALLY I HAVE 3 QUESTIONS FOR Application Engineers of National Instruments or someone who knows these subjects before deciding the best way to connect locally o remotely with security to Access from Labview:
1.- Is it possible to enter to Database BD5.mdb from ODBC and DSN with this owner?
2.- I want to connect remotely to Access database too. Is it possible to use Microsoft.Jet.OLEDB.4.0 using the path (.mdb file) without DSN?
3. Which is the optimal Provider for Microsoft Access?
I thank you beforehand for your technical support.
Peter Mst.
