LabVIEW Interface Generator for LabWindows/CVI Instrument Drivers
System Requirements
NI LabVIEW 7.1 or later
Windows 2000/NT/XP
Use the LabVIEW Interface Generator for LabWindows/CVI Instrument Drivers to create LabVIEW VIs for VXIplug&play and IVI-C instrument drivers from function panel (.fp) files.
Instrument Driver Network
Before using the conversion utility to create a new instrument driver wrapper, please visit ni.com/idnet to see if a LabVIEW Plug and Play instrument driver is available for your device. The Instrument Driver Network (IDNET) provides support for more than 3,000 different instrument models from over 170 different instrument vendors.
Recommendations
This utility was created for developers of C-based instrument drivers who wish to provide a LabVIEW interface, but do not develop a LabVIEW Plug and Play driver. By developing the C and LabVIEW interfaces together, it keeps the components synchronized, and eliminates the need for customers to create their own LabVIEW interfaces. Vendors should distribute the LabVIEW wrapper files with the associated VXIplug&play or IVI instrument driver, so that end users do not have to visit multiple web sites to download the complete driver.
If you are not an instrument vendor, we recommend that you use this utility only if you have instrument driver expertise. Access to the instrument driver source code is preferred, in case you need to edit the C instrument driver in LabWindows/CVI.
After generation, the wrapper VIs should be tested with the instrument.
Instructions
Once you install the software, simply access the utility from the Tools>>Instrumentation>>Import CVI Instrument Driver...menu in LabVIEW. This software replaces the built-in tool and provides feature enhancements.
For additional information on this utility, view the resources below.

Importing Instruments Driver from LabWindows/CVI

Does anybody have got wintools_32.dll library ?
I need it to convert LabWindowc/CVI Wintools Instrument Driver to Labview.
Could you send it to me?

Hi!
Thanks for your answer.
Exactly, I've tried to import LabWindows/CVI instrument driver to Labview.
This Instrument driver I've found here:
http://sine.ni.com/apps/we/niepd_web_display.DISPLAY_EPD4?p_guid=B45EACE3F04956A4E034080020E74861&p_node=DZ52176&p_submitted=N&p_rank=&p_answer=&p_source=External
During import procedure i was asked about wintools_32.dll library.
Personally I am interested in System Tray icons functionality of this driver.
I'm not sure that wintools_32.dll is Labwindows/CVI library, but i've searched Microsoft Windows pages with no results.
Regards.
Romek.

SCPI Instrument driver for LabWindows/CVI ?

Is there somthing like a plain SCPI instrument driver for LabWindows/CVI
that works with all SCPI-DMMs ?

Manfred,
You could look for a driver for another Keithly model or try one for a
different brand. They may be similar enough to modify easily. I realize this
goes against the idea of SCPI and standards but it is the best we have now.

Yokogawa UT driver for LabWindows/CVI 6.0 won't translate to LabVIEW 8.6?

The device driver for the Yokogawa UT series furnace controllers is in LabWindows/CVI 6.0 and I would like to use it in LabVIEW. I tried to use the utility to convert from LabWindows/CVI to LabVIEW, but it said it couldn't and that the device driver is from before LabWindows/CVI 5.01.
In any case, here is the series of events.
I downloaded the LabWindows/CVI to LabVIEW Converter, from
the page on LabVIEW's developer's connection that had the driver for the
Yokogawa UT controller.
From an empty LabVIEW Block Diagram, I click
Tools>>Instrumentation>>Create LabVIEW Interface to LabWindows/CVI
Instrument Driver...
This takes a little while to load. During loading an
FC_Interface_Main.vi runs, apparently trying to find a file.
Once that is done, the two options are Basic and Advanced. I leave
basic selected. I click next. browse to find the ykut.fp file from the
driver I downloaded.
I then click next. The error window that is seen in the screen shot is
then shown.
I called a tech support guy at NI about this, and I e-mailed him with all the above, but there was no reply, though the conversion utility is no longer available on the same web page as this specific device driver.
In any case, if anybody could give a little guidance, it would be appreciated.

Hello Screamingzebras,
I converted the .fp file to be version 5.5 and ran the utility that was mentioned. I have attached two files to this post. "ykut.zip" is the converted .fp file (version 5.5). "yut.zip" is the converted instrument driver.

Lack of IviDigitizer class driver in LabWindow/CVI

Hello,
I try to create IVI Specific driver in LabWindow/CVI version 9.0.1 for digitizer but I don't see any of this types of instruments. I have installed newest IVI Compliance Package 4.6.1. There is lack of few others IVI class drivers like counter etc. Does anybody know what I should do with this?
Regards
Tomek

Hi Tomek,
The support for IviDigitizer, IviCounter, IviUpconverter, and IviDownconverter was added in LabWindows/CVI 2009. Please contact us at [email protected] and we'll send you the missing template files.
Thanks.

Permission Denied Error when calling Matlab script from LabWindows/CVI

Hello,
I am reading in data from a DAQ and am writing it to a .csv file in LabWindows/CVI. I am then sending this data to Matlab to be filtered. I would like the filtered data to be accessed by LabWindows/CVI so that I can display it as a strip chart. I have gotten everything to work except the writing to a file in a Matlab script that is called from LabWindows/CVI. I am basically using the shipped example in found in the activex demo. (http://zone.ni.com/devzone/cda/epd/p/id/2994). I select the script that I want to run and each time it tries to open a file with write permissions I get a "Permission Denied" error. This occurs when using fopen() in Matlab. I have also tried using csvwrite() as well as dlmwrite(). Each one gives me a similar error. The script currently does not try to do any data processing. It just opens the file, if it is successful it then prints "hello" and then closes it. The script works well when it is run in Matlab, just not when it is called in LabWindows/CVI. Below is the script. Any thoughts, comments or suggestions are greatly appreciated. I am also open to using other approaches for sending data between Matlab and LabWindows/CVI. Thanks in advance!!
fclose('all');
[file, errmsg] = fopen('out.txt', 'w');
if(file<0)
   disp(errmsg)
else
   fprintf(file, 'hello');
   fclose('all');
end;
[file, errmsg] = fopen('out.txt', 'w');
if(file<0)
disp(errmsg)
else
fprintf(file, 'hello');
fclose('all');
end;

I am using Windows 7. I am running CVI as an administrator and was able to get rid of the "Permission Denied" error by going into the User Account Controls in windows and changing it to "Never Notify". However, this did not fix the problem of Matlab not being able to write to a file when the script is run from CVI. In the Matlab code below, It now gets in to the "else", suggesting that fopen() returns a good file handle. After getting in to the else statement, it will not actually write to the file, nor does it create it. However, I can make changes to the plot settings and those appear. Everything is functional when run from Matlab but when run from CVI, things get screwy with opening the file for writing. It handles the read well. It seems like there would have to be some file permission errors but, in the CVI program, I open and write to the file "in.csv". Any help is greatly appreciated.
clear;
fclose('all');
t = zeros(1000);
t = csvread('in.csv');
for i=1:1000
   t(i) = t(i)*4;
end;
[file, errmsg] = fopen('out.txt', 'w');
if(file<0)
   disp(errmsg)
else
   fprintf(file, 'goodbye');
   for i=1:1000
   %t(i) = t(i)*3;
   fprintf(file, '%f,', t(i));
   end;
   fclose(file);
   plot(t/3, t);
   ylabel('t');
   xlabel('Time (s)');
   title('Is this really working?!?');
end;
Thanks,
Chris

How can I convert a project from LabWindows/CVI 2010 to a Visual Studio 2011 project?

I have a good sized project, 12 source files, 14 headers, 1 uir, that I want to be able to edit and compile in MS Visual Studio 2011, MSVC++.
I remember being told that LabWindows dropped support for C++ in 2008 and no longer had a wizard for converting projects. I know I can go the DLL route, but I have never created a DLL before and wouldn't know where to begin with it. What would be the best way to go about this conversion?
Solved!
Go to Solution.

CVI 2010 still supports the Visual Studio Conversion Wizard for Visual Studio 2005/2008. We do plan to add support for VS 2010 in a future release.
If you need a VS 2010 project now, you can use the Visual Studio 2008 conversion wizard, then upgrade the VS 2008 project to VS 2010.

Update Station Globals from LAbWindows/CVI user interface

Hi,
I am having a requirement such that i need to update a station global variable to true or false based on the click on a button present in User Interface.
My Setup:
Labwindows/CVI 8.5
TestStand 4.2.1
Please advice me.
Solved!
Go to Solution.

Hi,
first thing, why have you posted this query twice, http://forums.ni.com/t5/NI-TestStand/Update-Station-Globals-from-CVI-UI/m-p/1317023
to be able to update a StationGlobal, you first need to get a reference to the Engine, this can be done using ApplicationMgr.GetEngine()
Once you have that reference you can then get a reference to the StationGlobals by the use of Engine.Globals(). this returns a PropertyObject.
So now you can use the SetVal methods to set your boolean, eg PropertyObject.SetValBoolean("MyBoolean", 0, True)
hope this helps

.exe Build from LabWindow/CVI 7.1 run exception under RTE 8.0.1

Below is the source file of test1.exe, which was built using LabWindow/CVI 7.1 environment, OS is Windows XP SP3
Due to some reason(install TestStand, or LabView, or ...), the Runtime Engine cvirte.dll, cvirt.dll (exists in c:\windows\system32\ )is 8.0.1
Executing this file, the GenericMessagePopup() will generate window's exception. But if executing GenericMessagePopup() before LoadLibrary(), it will be ok.
By the way, "cp3245mt.dll" is Borland's DLL. If load other DLL, everything is OK.
Is there any suggestion to solve the conflict between NI and Borland? Thanks!
// test1.c sourcefile
#include <windows.h>
#include <userint.h>
#include <stdio.h>
main()
// If execute the below line first. it will be ok.
//    GenericMessagePopup("Info", "Test","Yes","No",0,0,0,0,
//   VAL_GENERIC_POPUP_BTN1,VAL_GENERIC_POPUP_NO_CTRL,VAL_GENERIC_POPUP_BTN2);
   LoadLibrary("cp3245mt.dll");
   GenericMessagePopup("Info", "Test","Yes","No",0,0,0,0, VAL_GENERIC_POPUP_BTN1,VAL_GENERIC_POPUP_NO_CTRL,VAL_GENERIC_POPUP_BTN2);

Did you ever figure this out. I've set classpaths, the APPCPATH variable several
times with many variations and its not working for me, though the jsp thing is working.

Converting instrument driver from v4.1 to v8.5 or v8.6

Would anyone be able to convert the attached driver library from version 4.1 to a version that could be read by version 8.5 or 8.6? This is for a laser diode controller, and is the only version offered for download by the manufacturer (ILX Lightwave).
Thanks in advance for any help you can provide.

NI MAX entry for a Non-NI/VISA Instrument LabWindows/CVI Driver

Hi All,
Sorry in advance if this is not the right forum.
I have created a IVI class and specific instrument driver in LabWindows/CVI for a Video Generator. The generator is a networked, SCPI based instrument. It does not automatically appear in MAX like other NI based instruments.
How or what do I need to do to MAX to use the instrument? Is it as simple as adding the logical name, driver session and advanced driver entries to MAX? Do I need to create a new instrument in the HW section such that the driver session has a device to point to? I have been playing aroud with the networked instrument section in MAX and nothing seemed to make sense to me.
Any help would be greatly appreciated!
Thanks

Example LabWindows/CVI code for NI4351

Hi,
I'm using an NI4351 PCI DAQ card with the Ni435x
driver and LabWindows/CVI v5.5 (on Windows 98) to measure temperature
and voltage levels. Are there any simple tested code examples that I
could download, which use the NI435x driver function
NI435X_Check_and_Read(), called from an asynchronous timer for
continous scan? There are no problems when I use MAX (so hardware
problem is ruled out), but my code yields
occasional random temperature reading errors (looks like data
corruption to me). The NI435x_ functions return no errors. Can I use
lower level C driver functions instead of NI435X_Check(), NI435X_Read(), or NI435X_Check_and_Read()?
What does MAX use behind the scene? Of course, the MAX setup only scans
the one channel, so maybe this is why it works correctly. I have to
scan one temperature channel and six voltage channels though.
Many thanks,
John.

Humphreyy,
thanks for the tip. I tried it but it did not work, the same errors were present. Are there any other suggestions. I have racked my brain to figure out why this is happening and have come up with nothing. I am also getting a "Warning" message concerning the "KsMedia.h" file that says "Warning: Excess characters in multibyte character literal ignored." The warnings trace back to the "typedef enum" section of that file. Could that be causing a ripple effect that produces the error I am seeing in the other header files I mentioned??
I could really use your help and any more help that is available. I really don't want to use Visual C++, because this software is going to get more sophisticated and is to be used in NASA Langley's VISTAS simulator, an environment taylor made for National Instruments software.

Mysql database connection with Labwindows/CVI 2009 sql toolkit

Dear experienced users,
I am using the following software/hardware:
Windows 7/ Mysql database 5.6.15 64-bit with MySql ODBC 5.2 Ansi driver installed
Labwindows/CVI 2009 with sql toolkit
The user DSN of ODBC Data source administrator have been confiugred to one of mysql database. The test MYSQL Connector/ODBC is succesful.
The Labwindows/CVI build setting is configure to debug64 after trying debug (32)
The source code is from the example readtab.c with changes to the dsn I am testing
hdbc = DBConnect ("DSN=dvd_collection");
The error message I have is confusing me.
(it is in the attachd png)
I thought it was due to the 64 bit mysql database. That's why I tried the 64 bit build from Labwiondws/CVI. I alsow tried Labview DB tools open connect.vi. It shows me the same error.
Any suggestion is appreciated.
Thanks,
Jimmy

I always use connection strings of the form "DSN=datasourcename;UID=database_user_id; PWD=database_user_password".
Where:
datasourcename = The name of the connection defined in the ODBC connection.
database_user_id = One of the user identities created by the database administrator. Obviously the administrator will lock down the permissions appropriate to the task in hand.
database_user_password = The password that identifies database_user_id, again set by the database administrator.
Note that while it is obviously desireable to lock the permissions down as far as possible on the MySQL server, the more you do so, the slower the database will run, because of the way mySQL searches the permissions tables.

How to access the result list in teststand after execution using labwindows/cvi

I am developing a user interface in labwindows/cvi that runs multiple teststand sequence files and would like to combine their reports (generated in teststand) into a single file at the end of a UUT. What is the best way to do this? At the moment, I'm trying to access the result list local variable after the execution has ended using API calls from labwindows/cvi and an end-of-execution callback event but those run-time variables do not exist anymore. How do I get a hold of the result list array at the end of an execution? I would like to grab this variable and pass it along from sequence to sequence using labwindows/cvi and not teststand itself. Is this possible? Any help would be great.
Thanks in advance,
Luis
