How to get the data type of an object?

• 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 Date, month, year of the DateTimePicker

  Hi, I am using the DateTimePicker.

  There are several question about this command:

  1. how to get the Date, month and year?

  -With the help of myDateTime.value, I get this string ' Wed May 08 14:45 ICT 2013 '-> I have to manually analyze this? Because I need in format yyyy/mm/dd. Or can set the format of dateTimePicker.value?

  2 format on dateTimePicker self (on the user interface) is d/m/YY, I can't change to another format?

  Thank you

  dateTimePicker.value return a QDateTime not a string.

  You can get

  day = dateTimePicker.value.date().day()
  month = dateTimePicker.value.date().month()
  year= dateTimePicker.value.date().year()
  dateYYYYMMDD = dateTimePicker.value.date().toString(Qt::ISODate)
  dateYYYYMMDD2 = dateTimePicker.value.date().toString("YYYY/MM/DD")
  dateYYYYMMDD3 = dateTimePicker.value.toString("YYYY/MM/DD")

  Dear members,
  
  How to get the date for the first Monday of each month.

  Use the IW format - it will make independent NLS solution. And all you need is truncated 7^th day of each month using IW:

  select  sysdate current_date,
          trunc(trunc(sysdate,'mm') + 6,'iw') first_monday_the_month
    from  dual

• 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?

  Hello

  Looks like you have not defined the order of evaluation of Auditors. Administration > Dimensions > evaluation order > select plan type > moving accounts to another window, apply.
  Try the form again.

• Is it possible to get the data type of element of a queue to itself?

  Hello world

  I have a Q which has a cluster as data type of element.

  now when I want to enqueue

  I will use bundle-default-

  and for this I have to have my current data type

  (long cable as (perhaps after where I got the Q).

  My question is,

  If there is a method/property-node/something that allows me to

  the queue of wire inside Refnum and receive the data element type.

  If I can get into the top of bundle-default?

  (I really want to have this cable in all directions)

  is this the reason why I'm asking here

  aid for the Refnum of outgoing queue to get a queue, the method

  indicates the data type of element and so I hope that there could be a solution.

  thx for your time

  and soon

  j

  Get queue status must be output with the type of data (more precisely an array of the data type and an array of clusters if the data is itself a table). If you do not set the items back to entry to T, this should not even cost anything.

  That said, I agree with others that it is better to what actually a typedef.

• How to get the data center moref moref VM in c# using

  Hi all

  Could someone tell how to get managedobjectreference of data center using the VM moref? or any other easy way is? If anyone has examples of code in c# please share with me?

  Thank you

  Vijaya

  You can get the data center in which the virtual machine resides by the following search:

  VM Moref-> Parent (vmFolder)

  Moref folder VM-> Parent (data center)

  Parent of the virtual computer object will always be the vmFolder and the vmFolder object will always be a data center.

  This table how to get this line by id - name (id and the name of the composite key) whose date is the date of last weekend (last Saturday).
  for example, suppose to have IDs 123 values date February 12, 2010, 13-mar-2010 this date falls on the last Saturday 13-mar-2010, how to get the value of the line on Saturday last for all the unique id and the name?

  Here I have spent in the in clause 4 last weekend dates manually (although either has been calculated by programming) in front.

  Here's another option:

  SELECT     *
  FROM
  (
       SELECT     ID
       ,     NAME
       ,     MAX(CASE WHEN TO_CHAR(DT,'DY','NLS_DATE_LANGUAGE=ENGLISH') = 'SAT' THEN DT END) AS DT
       FROM     TEMP2
       GROUP BY ID, NAME
  )
  WHERE DT IS NOT NULL
  

  It is always useful to provide the following information:

  1. oracle version (SELECT * FROM V$ VERSION)
  2. examples of data in the form to CREATE / INSERT commands.
  3. expected results
  4 explanation of the expected results (alias "business logic")

  Hello

  It is not a very direct way to do it. What you can do is to call OCIDescribeAny on the table that you want to get information. You can then get the OCI_ATTR_CHARSET_FORM attribute for the column. If the value of the attribute that you get is SQLCS_IMPLICIT, that would mean its a varchar/char/varchar2 column regular. If you get SQLCS_NCHAR, this means that the column is NCHAR. You can get the example of it here:

  http://download.Oracle.com/docs/CD/B14117_01/AppDev.101/b10779/oci06des.htm#446491

  Just look for the section "Recovering for a Table column Datatypes".

• How to get the date of Sunday of the week

  Hello
  I have a column date 'start_date', I need to create a report for all the weeks from Sunday, for example:
  
  I need to get the dates of the week in the form:
  
  mm/dd/aa-23/01/11, 01/16/11, 09/01/11 and so on...
  
  Help, please
  
  Thank you...

  Hello

  To find the last Sunday before or equal to start_date:

  SELECT     TRUNC ( start_date + 1
             , 'IW'
             ) - 1          AS week_start_date
  ...
  

  You can also use an expression like that in a GROUP BY clause.

  It's not you NLS parameters. Always ISO weeks start on Monday. Your week begins 1 day earlier, that is why the above expression is the + 1 and -1.
  (According to the parameters of the NLS)

  SELECT     TRUNC ( start_date
             , 'D'
             )          AS week_start_date
  ...
  

  could do the same thing, but I still have rocommend with "IW"; a few extra touches is not big thing to pay for a guarantee that it will still work.)

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and INSERT statements) and the results desired from these data.

• 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?
