• Get the Data Type of queue

  I'm working my way through my first vi producer consumer and I have two questions.

  1 I am the queue data x, y samples acceleration waveform type z. The code snippet shows how to set the data type in the queue to get. It is rather ugly and disturbing, even if it seems to work.  Is there a way more elegant and beautiful to set the data type?

  2. the sampling frequency of the accelerometer is 5120 Hz.  The DAQmx Read buffer is 1024 length samples.  Therefore, it takes 200 [ms] to fill the buffer.  I put the metronome 100 [MS] to ensure that the producer is not without samples.  This means that the loop While producer will spend much of its time waiting.  Right?  Given the wait cost anything?

  In ProducerConsumerExample.vi of LabVIEW, the sampling frequency is 10000.  The size of the read buffer is 1000.  And the metronome is set to 100 [ms].  The sampling frequency of the device comes from the hardware device in the cDAQ.  100 [ms] interval comes from the PC.  It will not be a mismatch?  I would like to understand this before I put my metronome to 200 [ms].

  Then, can shed you some light on the behavior of the loop while you mentioned is not a metronome that is is punctuated by DAQmx? I think it would do a lot of rotation.

  It is not spinning as he waits inside the DAQmx Read for samples N must be obtained.  This isn't a request for data.  It takes time to collect these samples.  That length of time depends on your sampling rate and how many samples you request.  So because he is waiting inside the DAQmx Read, there is no need to add an additional wait.  Let the DAQmx Read limit the rate of the loop.

  It's actually like the loop of consumer for the consumer to the producer.  Playback of the queue will limit the rate at which that loop runs.  It should therefore no waiting.

• How to get the data type of an object?

  I have some custom classes, and I would like to make conditional function that behaves differently depending on the data type of the object. How can I do this?

  you could do something like

  var obj:CustomObject = new CustomObject();

  If (obj is Objetpersonnalise)

  {

  do something

  }

  or you could look at using getQualifiedClassName() or getDefinitionByName()

• Gets the data type variant for the selection of cases

  I don't ' know much about alternative, so I'll ask as many questions as possible on this subject.  If I have a table of varying, and each of these variations has been converted to a different data type.  This table will be the clue to a for loop and each item will be handled in a case inside the loop structure for.

  The issue is that I would like to take the variant data type, convert enum and use it to select the box on the structure of the case.  How do I do that?  Or what is the best way to do it?

• How to set the date type date of work

  This is perhaps a silly question, but I can't seem to get the data type date to work for a member account. When I go to the planning application and choose an account I want to put in a date entry account, the web form seems to show that the setting of the date works for the account. I even put my account type to be saved hypothesis. For example, I expect to see the date formatted in 10/20/2009 when I enter this value in the web form under my account "Hire Date". I also checked the display options in the preferences of planning. If anyone knows if this function works even on 9.3 or 11.1?

• is 10g - possible to know if the report to get the data in the CACHE?

  Hi, experts,
  
  Is it possible to know if the report to get the data in the CACHE (per share on the dashboard page)?
  
  of NQQuery.log?

  Forreging,

  Yes, it is possible to know if a query pulled from the cache to access Oracle answers/dashboards or not.
  If you find the part of the sentence "cache hit on request" within the NQQuery.log against any request, this request did get the results from the cache.

  Another way:
  Also under settings > Administration > manage Sessions if you find "Ref" > 1, which refers the number of times where a cache is used to provide results.

• What is the minimum value for the data type double?

  ... a more academic question: what is the minimum value of the data type double? I thought 'double', it is the 8-byte IEEE standard and what I remember, it's + - 1.7E + - 308.  The more different number of 0 should be 1.797E - 308.

  This is why I was a little surprised when I looked at the data output of my calculation of CVI, where I found the numbers with exponents of E-319 or E-324 as the smallest value...

  But I'm sure there's an explanation :-)

  Thank you for sharing with me,

  Wolfgang

  The largest number is indeed the order of + 1.7E + 308; There are a smaller number of - 1.7E + 308. Note that this is in fact the most negative number, which is the smallest by some reckoning. For the small beach of the Exhibitor, things get a little more complicated. 1E-308 can be represented with complete accuracy and resolution, but if you're willing to lose a few bits of precision, you can go down even further. For example:

  Double x, y, z:

  x = 1E-300;

  y = 1E7;

  z = x / y;               Give 1.000000000000000E - 307

  y = 1E8;

  z = x / y;               Give 9.999999999999999E - 309

  y = 1E18;

  z = x / y;               Give 9.999987484955998E - 319

  y = 1E23;

  z = x / y;               Give 9.881312916824931E - 324

  So, as you can see, values less than 1E-308 are possible, but they become increasingly more inaccurate and should not be relied upon.

  The format of Photoshop EPS files is partially documented here:

  http://www.Adobe.com/devnet-apps/Photoshop/fileformatashtml/#50577413_pgfId-1035096

  Photoshop includes a comment in the EPS so that it is able to read, it writes files insert it again. Third-party programs that write files EPS pixel-based can include this comment in EPS files, so that Photoshop can read their files.

  The comment must follow immediately after the % block of comments at the beginning of the file. The comment is:

  %ImageData: ""

  : Width of the image in pixels.

  : Height of the image in pixels.

  : Number of bits per channel. Must be 1 or 8.

  : Picture mode. Image bitmap/levels of gray = 1; Lab = 2; RGB = 3; CMYK = 4.

  : Number of another string in the file store. Ignored when reading. Photoshop uses this to include a grayscale image that is printed on PostScript printers without colors.

  : Number of bytes per line per channel. Will be 1 or formula (see below):

  1 = data are interleaved.

  (columns * depth + 7) / 8 = data are stored in line-interlaced format, or there is only a single channel.

  :

  1 = data in binary format.

  2 = data in hexadecimal ascii format.

  : PostScript the line immediately preceding the image data. This entire line should not occur elsewhere in the PostScript header code, but it can happen to part of a line.

  In addition, some information about other values of can be found here:

  http://Python.6.X6.Nabble.com/correctly-determine-image-size-of-a-Photoshop-EPS-td2096786. HTML

  2 - ascii

• Get the date of creation of virtual machines

  It is possible to get the exact time of creation of a VM?

  I see here in the tasks and events, but is not found. Maybe some PowerCli exclusive cmdlet for reports?

  These settings mean that there is no retention period.

  All events and tasks are stored in the database of vCenter forever.

  It could be that your virtual machines are created in a special way and that this method does not generate the eventtype is looking for the script.

  A way to discover, create a new virtual machine as you normally do.

  Then collect all the events of the last hour and list the eventtypes.

  Something like that

  Get-VIEvent-beginning (Get-Date). AddHours(-1) - MaxSamples ([int]: MaxValue) |

  Group-object - property {$_.} GetType(). Name}

  Maybe the list will shed light, why you do not see your virtual machine creation dates.

  If you see a lot of TaskEvents, we will have to look at the type of tasks.

  Like this

  $events = get-VIEvent-start (Get-Date). AddHours(-1) - MaxSamples ([int]: MaxValue) |
  where {$_.} GetType(). Name - eq "TaskEvent"} |
  Group-object - property {$_.Info.DescriptionId}

• How can I get the data view to display the same amount of time I save?

  I use the Sound and Vibration Measurement Suite.  In the data view, I display a graph of time, the power spectrum, the Color Map and the waterfall.  I am also showing strength in numbers group for several bands and doing cutting-edge research.  I record 100 ms of the transient wave.  In the data view, why the temporal plots show several seconds of data?  What determines how much time will appear in the data view?  More important, the power spectrum reflects the power for the entire of several seconds of data displayed?  Same question for power in the values of band and cutting-edge research.  I want to just this data displayed for 100 ms of the wave that I record.  So, how can I get the data displayed (waveforms) and power numbers come only 100 ms of the recorded wave?

  Finally, what is the best way to make account concisely the recorded data?  By slide numbers on the Documentation tab is not concise, because it comes with graphics, etc..  I tried save as ASCII/LVM, but I get a bunch of stuff intermiated I don't care.  Help?

  Hi TimRsandiego,

  SignalExpress is programmed to display graphs with default scales based on the type of action, it's reading. These scales and settings can be changed by right-clicking on the graph, and then select Properties.

  If you are interested to learn more about how to use SignalExpress, I would recommend checking out some demonstrations/tutorials on NI.com. You can find some of these demos at the following location:

  Let me know if you have any other questions.

• To change the data type of control/led

  Is it possible to change the underlying data type of the indicator or a control?  I a VI that I want to use that accepts any type of data (essentially data varriant) and display it accordingly.  I have different controls selected to display data of different types in the sense of data vs decimal boolean data vs integer, but certain types of data will be of type uint32 vs int16 vs uint64 etc..  Is it possible to programmatically change the data type, so I need to have all the combinations of indicators?

  The short answer is no. The long answer is that LabVIEW has not 'generic' controls that allow you to display any type of data (apart from the variant of course). There are several ways to address this problem, but all require you as the programmer to manage explicitly each type of data you could possibly meet. Here are some possibilities (in no particular order), please let me know if you would like to help a particular implementation of these.

  1. Force incoming data to variant, use the info option to determine the data type of the original data in a case structure (open G can do this VERY easy), have an indicator on the front panel for each type of data you want and hide those unused
  2. Use a sub-group of experts on the front panel and sub - vi call of to view specific types (that lends itself very well to encapsulate your data in a class and you leave OOP allows to expand into different types of data)
  3. Use a tab with the variant (similar to option 1) control put each kind of data in its own tab, enable only the current
  4. Do a Control-X to accept a Variant option 1 under the hood
  5. Just as a string of format and use a string indicator

  That's all I can think of right now, once again, let me know if you need more information/help on the options.
