NI 9263 remains at constant voltage after Labview exits

Hi all,
I have a problem that when I write a waveform to my NI 9236 on a cDAQ 9174 it remains at a constant voltage after the Labview program finishes until I unplog the USB cable. I would like it to go back to zero, so that I can leave it running by itself and not worry about burning the resistor for hours after the program finishes. I tried putting a DAQmx Clear Task at the end of the program, but that doesn't seem to help. Any ideas?
Thanks,
Matt

This is a basic question that has been asked and answered numerous times. If you want the device to output a certain value, you need to program it to output that certain value. Add a DAQ Assistant or a simple DAQmx Write as the last thing your program does.

Why "Acq&Graph Voltage-Int Clk.vi" does not get constant voltage for constant voltage input?

Dear All
Labview 7.1/XP/NI6221
I try to use NI 6221 to read analog input by using "Acq&Graph Voltage-Int Clk.vi".
The reading voltage does not constant and not correct value, when I put constant voltage.
How should I solve this problem? Thank you.
When I use "DAQ Assistant" to read analog input it work well.
Thongchai

Thongchai,
As I recall from an earlier discussion exchange with you, you are performing Reference Single Ended (RSE) measurements on channels 0-3, is that correct? In the example, there is no selection for the input terminal configuration on the DAQmx Create Task -- for M-Series boards on channels 0-8 the default configuration is differential. If you right click on this input and select "Create Constant", you can choose RSE and it should measure the correct values. Let me know how that works for you.

How can I add new content in iDVD to a DVD-RW disc which has ample remaining free space? After preparing the new video for burning and clicking on Burn to iDVD, I get a window saying the disc's already recorded and that I can either Erase or Eject.

How can I add new content in iDVD to a DVD-RW disc with a video previously successfully recorded on it? (The disc has ample remaining free space.)
After preparing the new video for burning and clicking in the File menu on Burn to iDVD, I get a window saying the disc's already recorded and that I can either Erase or Eject. My assumption has been that iDVD would automatically find the free space and continue with the new recording from there. I'd be grateful if anyone can shine light on this.

There are, but not with a DVD written as a movie disk. It must be closed when completed, or it doesn't work.
Apple's built in Burn utility also automatically closes any data CD, DVD or Blu-ray disk you burn. Doesn't matter how much space is unused, you can't use it. You'd have to use a more advanced disk creation app, such as Toast Titanium. I then have the option of choosing to write the data as a session:
I can keep doing this until the disk is full. If I've written five sessions to the disk, when I put it in the drive, five CD/DVD icons will appear on the desktop since the OS will treat each session as if they are separate physical disks. At any point you choose Write Disk when writing a group of data, that means you're closing the disk, and again can't add anything after that. So if I had written two sessions, and the third was Write Disk, it's over. I can't put anything else on that disk.

What's the maximum output voltage of labview

hi
i want to give 0 to 10v to the oscillator circuit so for that i would like to know that maximum output voltage of labview because i want to oprate my oscillator using labview program

hussey,
this discussion has no worth.
We KNOW that you want to generate voltage using the programming language LV.
Since no programming language in the world is able to generate voltage without dedicated hardware, repeating "I want to use LV to generate voltage" several times will not bring you anywhere.
What kind of hardware do you have for voltage generation mounted in you PC?
What else do you want to generate except DC voltage (controlling an oscillator could include also AC voltage stimulation...)?

How to get remaining time for baton after setting timeOut property

Hello,
Is it possible to get the remaining time for baton after setting timeOut, or do I have to maintain a separate Timer for that?
Been following this excellent tutorial here http://tv.adobe.com/watch/adc-presents/create-shared-forms-in-livecycle-collaboration-serv ice/

Thanks Nigel, before reading your reply, I came up with something like this, but it seems extending the Baton class is not enough, as I would need my own BatonProperty as well that uses this extended Baton class...
Also attempted to get some help here http://stackoverflow.com/questions/7116814/actionscript3-lccs-how-to-access-property-paren t-class-protected-var/7116882#7116882
Could this be made into a feature request for Baton and BatonProperty, se we could easily get the remaining time please? I guess I can wait for a future release.
/custom as file /

     import flash.events.TimerEvent;
     public class BatonExtender extends Baton

          super();
          _autoPutDownTimer.addEventListener(TimerEvent.TIMER,countDown);
          trace("CURRENT TIMER:"+_autoPutDownTimer.currentCount);
          trace("BATONEXTENDER added");
          public function countDown(p_evt:TimerEvent):void {
               trace("TRACING START countDown....");
               if (_autoPutDownTimer.running) {
                    trace(_autoPutDownTimer.currentCount);
                    //sharedTimer.value = String(90 - _autoPutDownTimer.currentCount);
               trace("TRACING END....");

PSE remains active in background after exit. How can I stop the program completely?

PSE remains active in background after exit. How can I stop the program completely?
Is there any command line option to force PSE to stop completely after exiting the GUI?
Opening the Windows Task Manager and killing the PSE process is not a solution!
(Context: I want to start PhotoshopElementsEditor.exe from another program with an image filename as command line argument. This other program waits in background until PhotoshopElementsEditor.exe has finished and pops up again after that. Since PhotoshopElementsEditor.exe continues to run silently in background, the other program will never come back.)

Hi - having the same problem with PSE process not ending on exit. Have you had any luck in resolving the issue?
Any advice would be appreciated. TIA

I can't stop "Reads in/sec" disk activity, remains at constant 20-30

I was hoping this community would be able to help me to solve this problem of constant disk activity I can't figure out. I'm afraid it'll kill my disk eventually.
Problem:
Constant disk access noise, "Reads in/sec" remains at constant 20-30 even when I have next to nothing running. It's clearly attempting to do something. Kernel task is one of the few tasks showing activity, but only a few CPU %.
This occurs only on one user account. If I switch the account to a clean one, disk activity stops.
In Disk Utility I've tried repairing permissions. Also, Verify reveals nothing abnormal.
Setup:
- MacBook Pro 2GHz / 2GB RAM / >50GB Free disk space
- FileVault
- Mac OSX 10.4.9

I'm running out of things to try. Any ideas on how might I fix this? Should I migrate my (massive FileVaulted) directory to a clean account or what?
MacBook Pro 15" Mac OS X (10.4.8) 2GHz / 2GB / ATI X1600 256MB

Seems you're running some sync program in that user account. Since it doesn't happen in another account, it's not system-wide. If you have one running, quit it and see if that fixes things. If not, then disable FileVault and see that fixes things.

How to measure constant voltage input through scxi-1530

I find that it readfs only when the signal is varrying otherwise it shows zero.

The module is hard-wired for AC Coupled input - hence you will only "see" a signal when there is an AC component. If you want to measure a constant voltage (DC level), I would suggest simply using one of the SCXI-110X series. It is a much cheaper solution.

LabVIEW exits while editing block diagram unexpectantly

Hi all, while editing block diagram in LabVIEW 2010, I have experience some strange behaviour from the software. I have two monitors, one has the front panel of main VI and the other - block digram of the specifed VI. When I switch from block diagram to front panel, and vice versa, every now and then the LabVIEW exits unexpectantly without the notice. Upon restarting the program again I get the undo.cpp error. I have attached the error log for my clarification on the type error that I am dealing with. Does anyone have any ideas why this is occuring? Thanks in advance for your help.

Thanks for all the responses.
I was using an existing VI as template to create a new program. There were nested loops in the original program and I needed the logic for the outter loops only for the new program. After deleting many objects in the 'yes' case in the inner loop, I was left with many loose wires in the 'no' case. And that's when my problem started, when I was trying to delete them. Yes, I tried rebooting my PC and that did not help. The problem seemed to get progressively worse, as crashing started to happen even when I was only selecting a wire. But somehow I was later able to select one wire, delete it, and did a save. Then I went to the next wire, and so on. My program is now cleaned up and I'm ready to go on. I will experiment more when the problem returns.
Thanks again.

Process in memory after System.exit(0)

I still see the process in memory after I exit the app. Do you think it is a JWS side effect?
Platform: W2K
Cheers,
Ivan

Ivan,
when you enable the 'java console' in Java Web Start->Preferences->Advanced->Show Java Console, you'll notice that you run into a java.security.accessControlException.
To avoid that, sign your jar file(s) and add the following to your jnlp file :
<security>
<all-permissions>
</security>
and it will work as expected!

Patrick

Why GPS symbols cannot exit after i exit ovi maps ...

i have one something problem for my hp nokia n86,
why gps symbols cannot exit after i close my ovi map. after i exit ovi maps the gps symbols still display, please help me for solved this problem , i used firmware 30.009, latest ovi maps v3.04

Okay then, the best solution maybe to remove Ovi Maps from your phone, backup all your contacts, messages etc. (not settings) to memory card or PC, remove the memory card and then try the resets in the order below, then re-installing Ovi Maps. Please note, if you don't back up your phone's data before resetting, you will lose everything!
Factory settings reset. In standby, dial *#7780# and the phone's security code (the nokia's default security code is 12345). This reset restores phone's original settings.
Soft reset. In standby dial *#7370# and the phone's security code. Soft reset deletes ALL your phone's data!
Hard reset (the three key code/reset). Turn off the phone. Press and hold three keys together, the green/talk key, the * key and the number '3'.Then, turn on the phone and don't let the three keys before you see the nokia hands logo/nokia boot up screen. Hard reset also deletes ALL data on your phone!
Good luck!
