Thanks smercurio the link appears to be broken so anyone who tries just remove the "." at the end.

alled in PCI-bus IBM PC, which does not have GPIB interface. Which way would be easier for developing my own instrument driver: a new GPIB controller + interface or 2915 Kinetic Sys. PCI-bus in-slot interface? Can the latter interface be used with LabView?
Many thanks.
Victor. I have got a 1500 Kinetic Systems CAMAC crate and 3932 controller. I want to use it with LabView installed in PCI-bus IBM PC, which does not have GPIB interface.

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.
Best of luck,

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.

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.

I have the same question,I don't know how to use the matlab DLL file in labview,
I hope someone can descripe the procedure in detail.

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!
Go to Solution.

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.

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.

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.

Looking for istructions/examples for using winsock in Labview

I'm looking for instructions or examples of using winsock in Labview. Looking in the NI examples I found an example using winsock UDP with Labwindows but nothing for Labview. Is the same function named different in Labview?

Thanks for the links. Unfortunately, I am specifically looking for the ways to use WinSock (I want to collect data from a number of remote locations and the WinSock would provide me with an effective way to
a) control the telephone number to be dialed (different for different remote stations)
b) provide me with TCP/IP, so I could use the full power of LabVIEW seeing a remote computer as an IP address (and being able to use shared variables, web server, data socket etc. instead of me having to program all that myself)
The other acceptable way would be to utilise a driver for a virtual network card (so I can programmically access it as TCP/IP on one side, and as a flow of bytes on the other, "virtual network cable", side). Any suggestions in this direction? By the way, it would be the best if the National Instuments would do such a virtualisation themselves. It would allow to utilise a number of solutions painlessly.

I try to make a dll in VB 6.0 and use it in LabView. I have some difficulties exporting the functions.

I use LabView 6.i and Visual Basic 6.0. So, I wrote a dll in VB and we want use it in LabView but I can't export the function. So, in LabView I can't choose the function name.

VB DLLs often embed ActiveX type libraries in them, and don't export any symbols. These DLLs are intended to be called via activeX, not at normal DLLs. Try to call your DLL by registering it with the system and then using ActiveX calls.

Anyone Use GIT with LabVIEW?

I think that the vast majority of people using SCM with LabVIEW are using either Perforce or SVN. Is there anyone who either uses or has used GIT, integrated into LabVIEW or not integrated? (I think there is a tool that uses the SVN protocol to talk to GIT)
If so what were your experiences?
=====================
LabVIEW 2012

There are several other posts on LAVA mentioning GIT (I think a lot where from FIRST). Post there (just link this post there as cross-post).
I personally think, that my arguments don't speak against GIT. I've been using SVN and Hg(mercurial) without any integration in the LV IDE (although I have some integration for Hg yet).
I forgot to mention: Using SVN you could use the plug-in from JKI. If your company invests the money, I'm sure it' a **bleep** good deal.
All these tools perform very well, even if you don't have the native LV support (as VSS, Perforce).
If you want a poll, you can check the NI-community features. Just setup one for SCC specifics. I was planning to do one myself, but I don't have the time. It' still not as good (from the quality and quantity of posts) a the forums, but has some cool features (wikis, polls). Advertise this on the most up-to-date posts on SCC issues. I and many others will drop in, I'm sure.
