Labview computer corrupted

hi
I had installed labview on a computer in 2003. The computer works on Windows NT2000, but it is creating problems. I am afraid that although labview software is working perfectly, due to my computer operating system malfunction, i may not be able to use labview. If i copy all the contents from that computer from the location C:/Program Files/National Instruments (where all the installation files for labview are located) to my new laptop which works on Windows Vista, can i run labview application from my new laptop?
Thanks

You really need to do an install and not a copy. There are just too many other files in other locations. You would spend too much time tracking down all of the support files.
Also, you don't mention which version of LabVIEW you have but Vista was not officially supported until LabVIEW 8.2.1. running the complete installation with an older version might work but it might not. If you install any hardware drivers, you must get versions that are Vista compatible.

Computer corrupted after partiton

So... I have been expirienced with using bootcamp before, and just recently decided to increase the partition size of bootcamp, so I backed up everything, deleted the partition, etc, and started a new, much larger one (about 130gb). I knew it would take a while, so i came back 45 minutes later, decided to open up another application, and BAM! Computer completely frozen.. I let it just sit there for 10 minutes, hoping that It would sort things out itself, but It didn't.. so I force restarted it. I knew it would not end well.. I started up the computer, and it started up as if it were trying to go into bootcamp, but it said it was an invalid disk. soo.... I started up my computer on the macintosh side.. and well.. my computer somehow thinks that the partition DID go through. It only have 30gb left on my harddrive (130gb in limbo somewhere) and boot camp assistant says that it can't recognise another partition, and I could If I wanted to make another partition with 30 gb.. So.. then I went into disk utility.. said there was no other partition, so I decided to verify the disk, and it said almost right away that the
"Invalid volume free block count"
"The volume Macintosh HD was found corrupt and needs to be repaired."
etc.. So, I put in the Installation disk, and booted into it. My computer was very, very loud at this point, and ended with the grey screen, with the message of doom, which needed me to force restart my computer. Beautiful. So, what now? I want my 130 gb back! haha.

I have a clone of my OSX partition. If the partition map corrupts, I use the clone to reformat the internal disk and re-clone the data back on.
Or if I had only a TimeMachine backup, I could restore an OSX then use the TimeMachine to get back all of my programs and data.
BootCamp sometimes kills the entire partition map, so OSX backups are critical prior to BootCamp.

How can I increase the speed of LabView computing?

Dear all,
I have a problem which I didn`t thought to face.
My problem is the folowing. I have Implemented some applications in Labview but with my great surprise the program is incredibly slow!
One of these was just a simple try to produce sinusoidal signal. I simply made a While loop where the sine of the "i" iteration number was calculated and then
sent to a NI- 6559 DAQ through an USB port and the DAQmx Assistant.
Well this simple program runs at 300 Hz Maximum. A similar program in C can without problems reach 20000 Hz!
Now I am asking if Labview is the wrong choice for more than 100 Hz applications and if it is not convenient to shift directly on C language.
Namely I want to let you know that the apllications I need require a loop speed of at least 800Hz.
Really I cannot understand why the system is so slow. It cannot be otherwise Labview should be unusable for the large part of the applications.
Can you suggest me what I am doing wrong, or maximum speed reachable on a normal 3 Ghz Pentium, 1 Gb RAM?
Best regards
Principiant

Hi Principiant,
I tried to reproduce your LV VI, which calculates the sine from the loop counter and get a cycle time of 0,125 microseconds, calculating the sine of every degree (0 .. 359). This means 45 us / cycle, which is 22222 Hz.
So it is likely that the communication with Your USB- device is the bottleneck. Is this device capable of buffered output? This would be preferable, it puts a block of data (pattern) into a FIFO and the device sends it to the DAC on its own.
greets, Dave

Is my Flash player or computer corrupt?

I am running Windows 8.1, Internet Explorer 11 on a Toshiba laptop. Recently had virus issues on my pc which was diagnosed and resolved where I bought the pc. Ever since the virus issue, my computer won't recognize that Flash Player exists. I have verified that it does exist by trying to reinstall it and the download screen says the latest version it is currently installed in IE. But I can't stream videos, iheart radio, and certain web pages have thumbnails and a other pics missing from there pages.
Does this sound like my computer has permanent damage or is there something I can do with Flash Player to get my computer to recognize it is installed? Thank You

I've heard this exact scenario from a handful of people, and I don't have a good solution. Because there is no separate installer for Flash Player (Flash is a built-in component of Internet Explorer), and you can't really uninstall and reinstall Internet Explorer on Windows 8, I can't figure out how to get you back to a pristine state.
Your best bet is to back up all of your important files and just reinstall the OS.
http://forums.toshiba.com/t5/System-Recovery-and-Recovery/How-To-Understanding-System-Rest ore-Refresh-Reset-and-Recovery/ta-p/342690
You can try "refresh", which swaps the OS out underneath your existing files; however, if it was my personal machine, I'd be more comfortable knowing that the machine had been returned to a reasonably pristine state after detecting a malware infection.

Passing control reference to subVI crashes labview

Hi,
using a image control (as indicator) provided by imaq Vision, I tried to pass the reference of the control to a subVI. On a computer it works and on a other (same labview version, same vision version, same os, same hardware and hardware drivers!), this crashes labview. I tried to close the control refnum at the end of the subVI, but that changed nothing to the issue. Now I use the reference as a global variable and it seems to work...nevertheless, I would like to understand what the issue and if I should remove any passing to subVI of control ref because this can potentially triggers an error. My correlated question is if this global passing is a "fake" workaround or have real chance of improving (this before going through the whole code for changing all passing of reference to subVI)
thanks a lot

Hi,
thank CoastalMaineBird for your answer
How do you know it's this issue which causes the crash?
When I remove this parameter from and the only property node in the subVi that write to it, I have no longer any problem. Moreover, to ensure that's really the "passing", and made a global variable containing the reference to this control and use my original SubVi that do access the control through its reference number
, and it works! In this last exemple, the only change is the way of transmitting the reference
What LabVIEW version?
8.0.1
up to date according Measurement & Automation update tool
Given that one computer works OK, and another crashes, I would say that
you are seeing the effect of something else, not the cause. If passing
a control ref via terminals was fatal, it would be fatal all the time.
You have some other sort of issue, perhaps timing of the different
machines triggers the bug, perhaps running out of memory, perhaps
LabVIEW is corrupted on one machine.... But I don't think changing all
your code to use globals would solve the real problem. Actually, saying that I wonder about problem of synchronisation. I know from Visual C++ that this kind of error happens if two process try to access the same control at the same time. This is typically an error changing from a computer to an other, and mutex or semaphore are the way to deal nicely with that. But does labview contains already such a securisation? If so, the global variable point on a single object and can "fell" the semaphore/mutex. But passing make a copy that will likely have two different semaphore/mutex but will point to a single control! Do someone know if I'm wrong in this idea or not?
Thanks

Bug in Formula node under LabVIEW 2010

appendix is my test project.
there is a test.vi in the project. The test.vi contains only a case structure with 5 SAME subdiagrams. Each subdiagram contains a formula mode. The formula code does some calculation with an 2d array of double.
If i run the test.vi under LabVIEW 2010(or SP1), it may cause LabVIEW 2010 corrupt occasionally. If I build application form the test.vi, and run the application ,the application will definitely corrupt.
if I delete one subdiagram of the case structure , the test.vi and the application both run well.
however, the same project works well under LabVIEW 2009.
so is it a bug with LabVIEW 2010?

'corrupt' means the program exit unexpectedly without any warning or error message. it just disappeared and you can't find it in the 'process' tab of windows task manager after that.
If LabVIEW corrupted, once i reopened it, there may be a error message dialog pop-uped before the LabVIEW interface appeared. The dialog said something wrong with 'undo.cpp'. I zipped the failure long to the appendix. I can't find any other error or warning message from LabVIEW or Windows ( I checked the Windows Event Viewer).
If the built exe corrupted, There isn't any message for LabVIEW or Windows neither.
I tested the project on my own laptop with Windows XP(SP3) Chinese Version and NI PXI-8810 with Windows XP(SP3) English Version which is my target machine.
Appendix also contain a exe build in my laptop. If I run the exe file, once I click the run button , it will corrupt. I wonder if it works the same on your computer.
Thanks for your concern.

I need to move the data from several cells in an excel spreadsheet to another computer's excel spreadsheet.

I have a data aquisition program on computer #1(not labview) that writes to an excel spread sheet and I would like to have a row of data transfered to another excel spreadsheet running labview(computer #2)on the same network. I would like to make this transfer of data either over the network or some other method to link these two computers (they are two feet apart). I'm not sure that datasocket would help , as it seems that the data to be moved must be written for datasocket in labview. My other alternative is to write drivers for the device that provides the data for computer #1. This is a new one for me as the user doesn't want to give up the non-labview program on #1.

LabVIEW.exe - application error

Hi.
I'm trying to use CIN to up-down flip a two dimensional array passed from LabVIEW. Everything seems to work fine when I run the .vi (flipper.vi). However, when I run another .vi (save_data.vi) that uses the flipper subroutine, it crashes LabVIEW.
Specifically, I recieve a LabVIEW.exe - Application Error:
The instruction at x-location referenced memory at y-location. The memory could not be "read".
Now I understand that somewhere along the lines LabVIEW accesses corrupt memory, due to a lack of array initialization or something. Unfortunately, that's about all I understand.
I'm using LabVIEW 8.0. Here is my flipper CIN code:
/* CIN source file */
#include <extcode.h>
/* stubs for advanced CIN functions */
UseDefaultCINInit
UseDefaultCINDispose
UseDefaultCINAbort
UseDefaultCINLoad
UseDefaultCINUnload
UseDefaultCINSave
/* Typedefs */
typedef struct {
   int32 dimSizes[2];
   int16 Numeric[1];
   } TD1;
typedef TD1 **TD1Hdl;
extern "C"{
MgErr CINRun(TD1Hdl dataIn, TD1Hdl dataOut);
MgErr CINRun(TD1Hdl dataIn, TD1Hdl dataOut)
       int32 rowSize = (**dataIn).dimSizes[0]; // number of rows of data
       int32 colSize = (**dataIn).dimSizes[1];   // number of columns of data
       (**dataOut).dimSizes[0] = rowSize;
       (**dataOut).dimSizes[1] = colSize;
       // up-down flip of data
       int32 i, j, arrayIndex;
       for(i = 0; i < rowSize; i++)
           for(j = 0; j < colSize; j++)
               arrayIndex = colSize*i + j;
               (**dataOut).Numeric[arrayIndex] = (**dataIn).Numeric[arrayIndex];
   return noErr;
Let me know if you have any ideas on how to possibly initialize the data that I'm passing into the CIN.
Hopefully this makes some sense. Thanks,

Hi, mrod,
The destination array should be resized before writing values with NumericArrayResize function:
The code above should work without troubles (hopefully).

PM 7.0 SP2 Pagemaker Corrupts files when it opens them

I work in the IT department at a hospital and the hard drive failed in our Print Shops computer. After reinstalling all the programs I'm having problems with page maker 7.0 whenever I open a document with it (from a networked drive) it corrupts the file and page maker crashes. That user's manager also has page maker and can open the files without a problem (before the first computer corrupts them). We had problems with Xp sp3 and in design/page maker so we have it running Sp2 so that shouldn't be an issue and I have tried reinstalling pagemaker and that didn't help anything. Anyone have any ideas that I can try to get this working correctly?

I just tried that approach, I copy pasted the file onto the desktop and it did not work, when it opened it just gave me a dialog box telling me that the file was not closed successfully the last time it was used. the file opens fine on another computer we have thats running pagemaker so I do not understand why it is getting this error.
when i click no, in order to open the last successfully saved version pagemaker opens but its blank, and there is no document to view

Write to Citadel database from LabVIEW?

Hi. I'm a newbie when it comes to Lookout and the Citadel database... so here's my question for you all:
We have various labview applications that log data from instruments. We would like to be able to take this data and store it as "tags" in a Citadel database.
What do you think is the best way to do this?
There are ODBC drivers for the Citadel database, but they appear to only allow you to query the database to retrieve values... you can't write data to the database (so its read-only).
Are they any "Lookout VIs" or Citadel VIs that can write to the Citadel DB from LabVIEW? Or a DLL or something?
Any ideas?
regards,
John Paul

Very nice question John Paul. I take it you already have Lookout and LabVIEW. In this case, with the latest versions of either, simply use the LabVIEW datasocket to publish the items on your front panel. Lookout then can subscribe to these once you register the LabVIEW computer. Once you have subscribed to them in Lookout, you are then able to set up logging. You may need to create an expression object to route the data to citadel.
If you just want to use LabVIEW and the Citadel database, you might try VI Logger. This works in our configuration utility - MAX, and also comes with a set of VIs for LabVIEW. One caveot, the Citadel database in VI logger is newer (and faster) than the Citadel database in Lookout. I believe NI is working to synchronize
the version in the future, and its hard to say when. So till then, you would not be able to merge data in the dislike citadel databases. However, you can always use and ODBC call set to extract from both and store in a more permanent SQL database such as access, oracle, ms back office, etc.

Missing function when running a .exe labview program

Hi
everyone,
I have used
a subvi taken from the RoboIO library ( http://www.roboard.com/labview/Labview_RoBoIOv15b.zip) to make up a program in order to run a
.exe version of it on another computer that doesn’t have Labview (just Run Time Engine
SP1 is installed).
The .exe
works fine on the Labview computer (after adding to the Build/Data directory the
RoboIO.dll, RoboIOv15b, winIo and WInIO.dll files.). I have no conflict message
when opening the Project explorer manager dependancies.
When I
launch the .exe on the second computer I get a message saying it can't find the
function I was talking about at the beginning of my post. (running another .exe without
this function works fine on this second computer)
It’s the
first time I am using a .exe on a "non-labview computer", so I must be doing something
wrong : not creating correctly the .exe program
Would anybody
have an idea what could be the problem?
Thansk a lot,
User

Hi
To deploy an application in a computer that doesn't have LabVIEW you could create an instaler than an exe.
You can find how to create an instaler in the LabVIEW help.

IPod gets corrupted everytime it's plugged in.

I've got an iPod classic and a giant music collection. Initially, I just copied everything in my library on to it. The problem is whenever I plug it back into my computer to add new music, iTunes recognizes it as corrupted. So I restore the iPod and recopy all of my Music onto it. Next time I connect, it's corrupted. This keeps repeating. It's like plugging the thing into my computer corrupts it. Otherwise it works just fine. I feel like something in my collection is busted. Any thoughts? Thanks in advance.

Problems new when bought?, corrupt pictures and videos, transfered music, not receiving calls

Hi,
as U can see I have some troubles with my phone and the sellers(Tele2) support says it's just dandy and fine. I've always had problem with receiving calls but ppl I asked refered to problems with the service but finally had enough and turned it in.
Also found out after a vacation that the phone randomly got the photos and videos corrupted (receive the message on my computer: corrupted file) One video in particular while recording a Dolphinshow ~24 minutes the video works fine the frist 40 secs with brilliant sound and picture but then I get a distorted still pictiure and the sound is a loop of the earlier sound and the time is ticking on until at its end.
I manually import music to my SD-card (Sandisk 64Gb SDxG) and it's both Mp3 and FLAC, now some random songs has a "staccato" quality to them as at some parts the songs fastforward at times.
After having problems upgrading the surf I had a look at my settings and there found out that the User(owner) of my phone is an entirely other phonenumber leading to a voicemail on another company(Telenor) so have some questions about that as I bought a new? telephone.
As I still have problems receiving calls and SMS, don't turn up until I randomly restarts the phone which I shouldn't have to do every day? Ther solution was to turn off 4G and only use 3G for a while, is that the way to solve the problem, to handicap my phone? very curious about that or if they are stalling for my warranty to expire?
To clarify, my arguments are against Tele2 but wanted to check with you if U got any thoughts about my problems as I really can't trust them as I don't find them acting, hmm well don't know what to say.
Looking forward to some answers
Yours!

Can I update startup.exe on an FP-2000 w/o Labview?

I want to set up a Fieldpoint system (FP-2000) with a program that runs automatically, and place it at a customer's site that has no internet access or Labview development system. Then, I'd like to be able to update the startup.exe file and any support files that are required. I've tried to simulate this by switching between 2 versions of the application through FTPing a new startup.exe file, but I lose the capability to run automatically when I do this. A better path would be to build an installer with application builder that would set up the FP-2000 directly from a non-labview computer, but I'm pretty sure that won't work. Worst case it might be possible to ship the FP-2000 back to me for upgrade, but I'd rather
ship software. Any suggestions? Thanks!

James S,
Thank you for using the discussion forums here at ni.com. Rather than building the executable on your host PC, I suggest the following course of action:
First, build the executable on one of the FP-2000's in your possession. Next, ftp the contents of the NI-RT/STARTUP/ directory to your host machine. These files can then be ftp'd to the corresponding directory on the desired FP-2000.
Before attempting this, you should verify that the firmware is the same version on both FP-2000s used.
