  If I understand correctly, you want to display a different set of data in a DataGrid control for each selected item in a list?

  I would just use link:

  This assumes that this list is filled with the data elements in a format similar to this:

  {

  label: "Label 1 list."

  data:]

  {col1: "col1", col2: "col2"},

  {col1: "col1", col2: "col2"},

  {col1: "col1", col2: "col2"}

  ]

  }

• Synchronization of two inputs frequency meter with several analog inputs

  Hi all

  I'm relatively new to LabVIEW and I'm trying to collect data from multiple sources with calendar sync on the acquisition, but I can't understand. My problem is that I have two inputs frequency meter, an optical tachometer reading one pulse per revolution and a max flow meter machines with a 12000 k coefficient. I can't find a way to synchronize the calendar with my multiple analog inputs. I tried to first get the speedometer to synchronize with the analog inputs following the example linked here. (https://decibel.ni.com/content/docs/DOC-10785) So far every time I run it I get an error on the DAQmx read timeout or an error "several sample clock pulses have been detected" (see image).  It seems if I slow the way to down to say 10 hz and make sampling rate ensure that the tachometer signal is more than 800-1000 rpm (13-17 Hz) before starting the VI then the program will run without error until the ROTATION speed is below this threshold, then the "sample Multiple clock pulses" error occurs.  The code is attached below.

  Does anyone know of a better way to synchronize the entries of frequency of the counter with analog inputs?  I would like to have a VI that can display 0 RPM (and possibly 0 flow as well, but I think I need to understand the timing of a meter before I have add another, because it seems that I can't have two counters to the same task). Any help on this would be greatly appreciated.

  LabVIEW version 13.0

  Chassis cDAQ-9178 with NI 9401 for both counter inputs and NI 9205 for the analog inputs.

  Thank you!

  I know the error requires to restart the task at least (this particular error puts the material in a State that cannot be recovered from during execution of the task - I've been down this road before) but I'm surprised that you would have to delete and re-create the task altogether.  And then I had to do this to workaround other questions in the past.  It is awkward and should be considered a bug, if this is indeed the behavior.

  Honestly, regardless of this bug, the way the material dealing with the situation of several sample clock edges makes measures of sampling frequency clocked essentially unusable for purposes of synchronization (in my opinion anyway) If you encounter a more slow than your sample clock rate.  You are supposed to be "synchronization" of the measure, but it really no longer applies if you have to restart the task over and over again (if you must delete it or not).

  Workarounds can get kind of creation (which isn't really a good thing).  For example, you can configure a measure of implicit frequency to keep a buffer of frequencies and use a leader board task (source is the frequency signal, sample clock is the sample clock HAVE) to establish a correlation between the index of your buffer of frequency for singing HAVE sample clock.

• Several analog inputs with different configuration differential/CSR

  Hello

  Can anyone tell how to measure two analog inputs with different configurations using a USB-6009?
  I am aware of the syntax for create virtual channels for the channels DAQmx create virtual so I created two strings using Dev3 / ai0:1 but I would like the first string of the CSR and the second to be differential.
  So far I have found no way to specify the configuration of the separate channels.

  Any ideas much appreciated!

• 6036E PCMCIA + DAQmx (analog input) seems to only read in blocks of 512 samples of data

  Hello people,

  I ask this question before I post any code or software versions etc to see if there is a simple answer.

  I use a PCMCIA card 6036E to read an analog input channel (DAQmx... i. e create task, create the channel, set the altimeter (continuous samples), task, read in a programmed software loop while (ASAP)).  No matter how I put my sample rate, number of samples per channel (i.e. size of buffer), or the number of samples to be read, it looks like I can get multiples of 512 samples.

  Here are some samples freq (Fs), the 'number of samples to read' asked and the actual number of samples read:

  FS numberOfSamplesRequested numberOfSamplesActuallyRead

  200Hz   20                                                 512

  1000 1024 5000Hz

  2000 2048 5000Hz

  QUESTIONS RELATING TO THE:

  1 is this 'normal' behavior a 6036E PCMCIA card?

  2. in the case, has anyone who may have seen this problem determined the cause and how to "fix it"?

  Best regards

  Systems PCI DMA is used to transfer
  the data, daqmx and receive messages when the number of samples are
  acquis. Now on PC-card that does not work and the data is transferred
  When the edge buffer is full (after 2 k of data) to 2 channels
  10 Hz, it can take some time.
  There is a work-around, there is a property where you can set the transfer mechanism (I have not daqmx on this PC), or the daqmx polling mechanism. Try these.

• I have my windows automatic update. the other day, my windows updated and Ive had problems of e-mail and online video problems. I have vista Home premium OS. any suggestions?

  can receive email, but not able to send after the recent ('important') updates of windows have been installed.
  also can't see videos on facebook because of the mistakes because of these updates.
  I have the my windows update set to automatic and noticed these problems after an update has taken place. I did a system restore and everything worked fine. Needless to say the next day, the same thing. I even went to the windows update to manual setting, and it is always updated by itself. This made 4 consecutive days. now when I go to system restore, I don't even get the opportunity to go beyond 5 days! video errors on facebook tell me that "the video is unavailable" and "video has been deleted or is not visible because of the privacy settings. I also noticed that most installed updates are updates to windows security. and my windows update seems to be popping up constantly telling me ago over updates to install.

  Hi Unhappy72,

  I'm sorry that you are still facing the same problem. I'll be more than happy to help you.

  1 log on to the computer using an account with administrator rights

  2. click on start, type msconfig.exe in the start search box and press ENTER to start the System Configuration utility.

  If you are prompted for an administrator password or for confirmation, type your password, or click on continue

  3. on the general tab, click Selective startup, and then clear the check box load startup items. (The check box use the file Boot is not available.)

  4. on the Services tab, click to select the skin all the Microsoft services check box, and then click Disable all

  Note: Following this step lets services Microsoft continue to run. These services include networking, Plug-and-Play, record of events, error reporting, and other services. If you disable these services, you can permanently delete all restore points. Do not do this if you want to use with existing restore points system restore utility

  Once you have disabled all services that you can check if you are able to play the videos. If so, you can try the divide and conquer method to find what service exactly the origin of the problem. For those who follow the below given link:

• A change from all the other layer styles layer style? Disable this option?

  I'm sure that there is a simple answer to this, but I can't seem to find it. When I apply a style to a layer in CS2, and lets say that I give it a drop shadow that is different (it is 110degrees instead of 90 degrees for example) compared with other shadows in my other layers, the layer style curent will change all the other layer styles in all areas. I looked everywhere for some settings to modify for each layer individual keeps his own style, but I can't seem to find it. I want that each layer to have his own style attribute and does not change the rest, how to fix this?

  Thanks for your help!

  Tegan

  You should uncheck the global light option in the layer styles dialog.

• error 201003 trying to read several analog inputs on 9172 chassis

  I'm new to the Forum, so forgive me if this has already been answered.

  Input module im using the chassis c - 9172 DAQ with an analogue of the 9221. I want to read three transducers in real-time. The problem I have is two if the transducers are 7.5 K lb/po2 rated and 100 psi rated, making me use two different scales. I can do the N-channel on playback of the system but only will allow me to read the two 7.5 K transducers.  I use the DAQ assistant, I create a virtual channel and add all components to read from the module. When I create another instance for the third transducer, it gives me the error: error 201003, module is already reserved. I need help please. Let me know another way to do what im trying to do. I used the DAQ assistant, but the data is incorrent on the transducer of 100 lb/po2, which explains why I manually create the virtual channel.

  If you had searched the error code or message, you would have seen several posts on this common problem for beginners. Simply, you cannot use several tasks for a single material resource. Use several functions Create Channel, each connected to each other and specify your scale.

• gpedit.msc is not listed as any of the other command internal nor external, but Windows Defender is expected to be cut in group policy

In the command window, I am told that it is an external or internal order. Regardless, as if it is performed with or without administrative privileges.

  • You have problems with programs
  • Error messages
  • Recent changes to your computer
  • What you have already tried to solve the problem

  Have you checked the entires in gpedit.msc to Computer Configuration / Administrative Templates / Windows Components / Windows Defender to make sure that the check box turn off is not checked?

  Are you now or have you ever been plugged to a domain network where server group policies were in effect?

  Go to start / Control Panel / Administrative Tools / Services and scroll to Windows Defender and make sure it is set to automatic and started.

  What software AV (name and version) are you using?   Several packages different softare actually disable Windows Defender when they install and I'n not sure how they do it - it can be a group policy.

• I changed ownership to the TrustedInstaller c: to another account and tried to stop him too late.

  Operating system - Windows 7.

  For cleaning neglected someone's PC, I did a huge change without having to learn first about it.

  That's where I was:

  -Drive C: properties,

  -Security tab

  -Click on the "Advanced" option, which has opened the

  -Advanced window of the security settings for the OS (C :).

  -Owner tab

  -in the box under "current owner:" he showed the name "Trusted Installer".

  There was the possibility of "' a change of ownership to:" under which she listed the person name that has computer is, what I'll call 'John Doe'. "

  Quickly, I assumed this TrustedInstaller was against malware, causing some problems.  I picked the name of the person and proceeded to spend the entire C: drive content to 'John Doe' property.

  I tried to stop him, hoping that the cancellation of the changes, rather than their "application" would avoid this action.  But, no luck.

  I tried a restore system for two hours before point, but the owner is still listed as John Doe.

  I want to go the drive C: TrustedInstaller property, as it is supposed to be.

  Can someone help me?

  Thank you
