Is LabVIEW 7.1 Aug2005 identical to LabView 7.1 May2005?
I am attempting to have a coworker at a remote site set up their PC with the exact same software as one that I have here. I used the August 2005 CDs from Developer Suite. My coworker tells me that he has the TestStand 3.1, and the Device Driver CDs from the Aug2005 Dev Suite shipment, but he can only find LabView 7.1 from the May2005 delivery.
I would like to safely assume that LabView 7.1 is LabView 7.1, regardless of whether it was shipped in May or August, but it is really important to me to make absolutely sure that we end up with the same software v...DSC module 7.1 labview 7.1, new controls and functions not showing up in labview

...Differences in CIN management between Labview 5.0 and Labview 7.1 ? #2
I'm using a VI on a two photon microscope. It steers the laser beam in the sample (quite the same way as a TV scan, scanning a fast line on the X axis, then moving the line down) controlling two mirrors by the PCI-MIO-16E-4 Multifunctions card on traditional DAQ and at the same time it serves as the acquitision through a non-NI DSP Multifunction-board with on-board buffers and hight data throughput (70 Mb/s).
It is this part of the program which gives us strong headaches since we have upgraded to a new PC.

Hello all !
I have a multithreated software developped under Labview 7.0.
Under this version, multithreading can be enabled/disabled via the options menu / performance & disk section. This is not present under Labview 8.2.1.
My software works properly under LW7 but is slower under LW8.2.1...how can I configure labview and or my vi to make it running as well as under LW7 ???
Is there a "hidden" option to enable/disable multithreading under LW8.2.1 ?
Thank you for your help
To disable multithreading, add ESys.StdNParallel=0 to the ini file.

However, it is not celar that this is the problem. Did you save the entire hierachy under 8.2.1 after conversion (of course after making sutable backup copines of the 7.0 version ;)). Freshly converted, but not yet saved code runs typically much slower.
Also, what do you mean by "slower" 10% slower, 10x slower? How do you measure speed?
Thanks for your quick answer altenbach.
The tips given at this link will really be useful to me!
It seems that I made a wrong conversion of the files...fortunately I made suitable backup of the 7.0 version :smileywink:. I will investigate mor...How can I run a labview 7.2 vi in labview 8.2
We have several versions of labview running different test and control functions in our facility. There are labview 7.2 VIs in a production setting I wish to reproduce in the test lab. Can I convert them to run on 8.2 or do I have to recreate them in 8.2. I tried to open one in 8.2 and got multiple SubVI's that were not in my program library.. most dealing with AI manipulation.
And make sure you have backup copies of your 7.x code. Once you load and save in 8.2, it is a lot of work to get them back to 7.x.
Note I used 7.x because I am unaware of LabVIEW version 7.2 even existing. 7.1.1 was the last release prior to 8.0

Are you talking about a 7.1 exe or VI? An executable will run with 6.1

I have labview version 8.2.1 installed on my computer.
The other day I installed some application by another company that must have installed Labview Runtime Engine 7.1.1 on my computer. I didn't need that program anymore, so I uninstalled it.
Now anytime I try to run any labview programs on my computer, I get several dialog boxes wanting me to put NI Labview Runtime Disk #2 in my CD drive.
How can I get rid of these dialog boxes?
This issue seems very strange but I do have a few suggestions. The first idea that comes to mind is to repair LabVIEW 8.2.1 from Add/Remove Programs. If you no longer have the 8.2.1 disks or if a repair does not work, you should install the LabVIEW Run-Time Engine 8.2.1. This download is available on NI?s website.
These two ideas are the easiest ways to possibly fix things. If they don?t, a list of all the NI Software you have installed would be helpful for going forward.
I?m sorry to hear that didn?t work. It sounds like leaving that software on your computer may be the easiest solution. However, if you are interested in spending more time on the issue, you could use the MSIBlast utility to find and delete the 7.1 installers. This utility is available at ftp.ni.com/outgoing . Other than this, reformatting you computer is the only sure fire way to remove the problem (along with everything else).

test station with PXI chassis and items such as 5112 digitizer, 5411
Arb Wave Gen. NI-Scope version 2.6 came with the 5112. When I

I would be extremely grateful for your assistance in helping me understand the timing in LabVIEW.
Here are the details of the system. The data acquisition is done using a simple LabVIEW 8.2 based program consisting of a DAQ Assistant VI and a Write to Measurement File VI, which writes data in TDM format (binary with XML header).
The hardware consists of a 1042Q chassis that contains 2 PXI-6133 cards. 16 transducers are connected to these 8 channel cards. The chassis is connected to a PC by means of MXI-4 fiber optic cable and a PCI-8336 card.
I would like to sample all 16 channels simultaneously at 500 kS/s for 2 secs. or 1MS/s for 0.5 secs.
When the signals were sampled at 500kS/s x 2secs., the time column looks like this when opened on DIAdem.

In a local client / server arrangement I use a server sided global VI
for buffering information from the server to the client. Server VI and
global VI are assumed to run in a common application, the client in
The server exports the global VI but the client can't get access to it
and thus is not able to call the global VI by reference. Within one and
the same development environment everything works fine (example 1).
After distributing it into two projects with libraries or after
application building it doesn't (examples 2a & 2b)
A similar construct worked under LabView 7.1 but I got lost in
VI-settings, build settings and computer instance settings under 8.2.1.
The attached simplified examples show how it is intended to work (example 1) and the problems occurring (2a&2b).
It also includes a description of usage.
Can anybody help?
thank you for your example modifications. I am sorry that I still can't get them running. After adjusting the library path the program did what I expected: it simply opened another instance of the GLBVI....
I assume that it worked when you tried it. Maybe the difference simply was, that you opened both examples in one common lvproj environment (which is similar to the situation in example1). The both - client and server - use the same instance. But when operating it with two lvproj opened or later in two separat compilations client and server start their own instances and thus the da...LabVIEW 7.1.1 w/.NET 2.0 patch, objects still missing
A co-worker [using LV 7.1] asked how to do a Clipboard.Clear while manipulating an Excel document. I don't know what the easiest way is. Looked briefly through the Excel Automation methods and tried Windows User32.EmptyClipboard which gave an error I didn't explore - am currently looking at a method of the .NET System.Windows.Forms\Clipboard object. This object is visible in System.Windows.Forms(126.96.36.199) assembly - but only when I'm using LV 8.2(.1). I was unable to see this 188.8.131.52 assembly from LV 7.1.1 until applying the 7.1.1 .NET patch - now the 184.108.40.206 assembly is listed in the object-browser, but the "clipboard" object is not a listed member. :smileysad:
I'd be grateful for your Clipboard.Clear solution - and any info as to why the .NET-patched 7.1.1 should or shouldn't see all 220.127.116.11 objects. :smileyhappy:
Thanks for the ideas tried everything, critical updates were up-to-date. Installed NET 3.0 though it seemed silly - but it was the only net-related non-critical update. Restart, no joy. Had 7.1.1f2 but re-"installed" it anyway - it's essentially a couple (3) replaced files. Still no clipboard object to select in NET-constructor browser.

Hello, For a independent study Labview class I'm taking, I am trying to create a program that will input two different wav files and combine parts of them together for audio output. The first file I am trying to cut out the bass lines and replace them with the bass lines from the second file. Kind of like turning the second file into a karaoke version and filling in the vocals with the vocal line from the first file. A second option is simply taking the instrumentals from a song (a wav file containing only the bass line) and adding them to the first file after cutting out the original bass line of the first if this isn't possible. I found the attached file while searching for information/examples as to how to do this - it was originally posted at:http://forums.ni.com/ni/board/message?board.id=170&message.id=74618&requireLogin=FalseI tried running the file in Labview 8.20 and it came back with the error that "Build Screen.vi not found." I have searched for this file to download but have come up with nothing.Also, any tips/pointers/comments (or "there is no way this is possible") are much appreciated and very welcome. I have been searching to see if there is anything like this that has been done before and as of yet haven't been able to find anything.

I have an application in LabView 7.1 that is expecting vi.lib\DAQ vis to be loaded from the directory \LabVIEW7.1\
Which version of NI-DAQ would this indicate that needs loading?
I have NI-DAQ 6.9.3 and if I load that and tell LabView to load the vi from that driectory, things seem to load without problem.
Is NI-DAQ 7.2 the correct version and will it load in this directory?
Would NI-DAQ 7.2 be the first to be used under LV 7.1? I think it is still available for download.
I have an app that needs to stay at LV 7.1 but I don't know what version was used for NI-DAQ except that the vi.lib was being looked for in the LABVIEW 7.1 directory.

Thank u in advanced!
Message Edited by dhirah on 04-07-2008 05:08 AM
I'm not sure exactly what you are looking for. You have something you want to test? For that test you need some board to provide the I/O for the test? The first thing to do is to define all of the I/O that you need. How many analog inputs/outputs/digital inputs/digital outputs? What is the range of the analog signals you have to source/measure (voltage/current/frequency)? What's your budget? When you have all of that, then you can start looking for test equipment that meets your specifications. You can contact your local NI Sales Engineer for help in configuring a system. For non-NI test equipment, external instruments connected via GPIB/USB/Serial/Ethernet, are usually no problem controlling with LabVIEW. Look for instruments that have drivers already written for them but writing your own driver is always possible. For pc based instruments, ask the vendor if they have a LabVIEW driver.
