• Controlling the flow of data

  Hello

  I'm working on a program in which I have to control the flow of data on the wires.

  The task is that the data should not pass until a given value is generated. And the program remains the playback thread until this value is generated.

  While the value received, now the passage of data to all loop regardless the data that is generated on.

  That's why I created two loops while we research this value and the other is the principal who must perform processing when the specified value is generated (taken in the first loop).

  It could also say that "wait until the reception of a certain value.

  

  The first loop is created just to wait until a value of 3.

  The second loop is the principal who must deal with.

  
  

• How to change the value of string clustered, to implement using the node value of property instead of writing directly on the flow of data or using the variable

  new to labview :-) and I have a problem when I want to change the value of a string in bunches, and I want to implement this using the node value of property instead of writing directly to the stream or by using the variable, enclosed is the picture.   No matter, I have change in cluster (control) or value of Popery out (indicator) cluster, the value (sensor 7) dataflow keeps unchanged even I gave the new value by value of property node. Thank you to give me some advice about this.

  

  Hi GerdW

  Thanks a lot for your answer. The reason I'm stubbornly tring to break the flow of DATA is: we have a test system that have about 100 screws, they have a few connected flow, some of them will be unbundling a cluster dataflow chain to check the value in order to make the different cases.  Now I want to insert user event by changing the control and influential cases during run time.

  As I initially uses a global variable (to control cases) instead of unbundle string data flow, it works well.  But then, I found there are a lot of screws that are using the string unbundle.  One of the 'lazy' means, I tried is to change the value via the property node (because that way, I did not need to find all the places where using the unbundle string and replace them with the global variable), then I noticed a problem with "dataflow", the value in the stream of cluster in fact will not be changed by changing the value of the property node.

  I did a test with VI simple (like the picture in last post), and after reading your advice, I tell myself that I need to understand the concept of "DATAFLOW" in labview, it seems that my "lazy" way can not work in this scenario.

  I have attached the criterion VI here, have you furthur suggestions on what I can do in this case?

  Mant thanks!

• determine the type of data

  Hi all
  
  I've got procedure of inserting data in table1 value1 column.
  My need is to determine the type of data entered by the user.
  If the data type is not number user should error.
  How can I make it?

  The easier and more reliable way would be to declare the formal parameter as a number, such as:

  SQL> create procedure p (p_num in number) as
    2  begin
    3     null;
    4  end;
    5  /
  
  Procedure created.
  
  SQL> exec p('a');
  BEGIN p('a'); END;
  
  *
  ERROR at line 1:
  ORA-06502: PL/SQL: numeric or value error: character to number conversion error
  ORA-06512: at line 1
  

  If you cannot do this, or want to be more "user friendly", so the only alternative is to test and trigger an error like:

  SQL> create procedure p (p_str in varchar2) is
    2     l_num number;
    3  begin
    4     l_num := to_number(p_str);
    5  exception
    6     when value_error then
    7        raise_application_error(-20001, 'I know I said it was a string, but I really want a number');
    8  end;
    9  /
  
  Procedure created.
  
  SQL> exec p('a');
  BEGIN p('a'); END;
  *
  ERROR at line 1:
  ORA-20001: I know I said it was a string, but I really want a number
  ORA-06512: at "OPS$ORACLE.P", line 7
  ORA-06512: at line 1

• Script or command to determine the ESX installation date

  Hello

  I was responsible for getting the date of installation of each ESX host in my infrastructure. Y at - it a script or the cmdlet that is used to determine this information. I have looked around, but discovered nothing. Any help is greatly appreciated.

  G

  As I know there is no property that gives you the installdate.

  There are alternatives, but all do not give a solution that will always return the correct date.

  I prefer to look for the oldest statistical data for the host

  -This requires that statistical data are retained indefinitely

  -If the host has not added to the vCenter immediately after installation, the returned date might be off significantly.

  -due to a bug in the cmdlet Get-Stat, I use the QueryPerf method instead of the cmdlet Get-Stat

  $esx = Get-VMHost MyEsx $perfMgr = Get-View (Get-View ServiceInstance).content.perfManager
  $spec = New-Object VMware.Vim.PerfQuerySpec $spec.StartTime = (Get-Date).AddYears(-2)
  $spec.Entity = $esx.ExtensionData.MoRef
  $metric = New-Object VMware.Vim.PerfMetricId $metric.counterId = 2 $metric.instance = "" $spec.MetricId += $metric $stats = $perfMgr.QueryPerf($spec)
  
  Write-Host $stats[0].SampleInfo[0].Timestamp
  

  The script assumes that it must be less than 2 years since the host was installed, but you can easily change that by changing the setting to the AddYears method.

• Determine the Sources of data used by Applications

  We are still currently using MX6.1. Our team of Oracle is upgrading to a large amount of databases (at the beginning of DEV, then QA, then Prod) which connect our various applications see I'm pulling my hair out I am trying to figure out/map which applications use a particular data source. I know that when I go into a sandbox given via the web administration I see sources of data that an application is allowed to use. It would be terribly helpful if I could just go in the variety, defined data sources and see what sandbox (es) currently allow connectivity and would thus know which applications would be affected. Someone can shed some light on my dismal existence? Thanks in advance.

  Your method is easy.

  All the your DSN are saved in the file "cfroot\lib\neo-datasource.xml". You can open with an XML editor and view the settings.

• WRT 1900AC slows down the flow of data with Brighthouse

  I recently bought a WRT 1900 AC.  Synchronize straight up with my Brighthouse modem, but I noticed that the maximum data rate I can get through wired connections is 7.2 Mbps.  When Brighthouse is out focus on the system, they read 22 Mbit/s on the modem.

  One reason why the router should be reduced my flow so much?

  Excellent advice.  It's the correction that I needed

• Determine the next deadline Date

  I have a table that contains the definition of the schedule, a schedule defines when a document should be submitted to a specific part. The definition of annex contains a start date and end date, a type of recurrence (is pointed it out a time or on a recurring schedule) and the frequency to which the document should be filed. The second table provides a history of comments, this option stores while it was due and when it was received. Earlier this month, pre-fill us the layout table with a list of records that will be due for the month. For example, on 1 September look us through all schedules and determine which ones would have a record due to a certain point in the 9/12 and then to create a record in the presentation table.
  
  I have questions, the calculated the tender documents list to work properly.
  
  The DDL and DML will be in a follow up post
  
  Here's the query I use currently and is unable to work properly.
  

       with schedules as (
         -- generate a list of valid permit schedules
         select s.schedule_id,s.submittal_frequency_months,s.recurrence_type,
         s.first_due_date,s.requires_approval,
         round(round(months_between(to_date('09/01/2012','mm/dd/yyyy'),s.first_due_date))/decode(s.submittal_frequency_months,0,1,s.submittal_frequency_months)) recurrence_number
         from permit p join schedule s on (p.permit_id=s.permit_id)
         where p.permit_id=nvl(:p_permit_id,p.permit_id)
         and p.permit_status_type_id=1 -- only active permit
         and s.recurrence_type in ('One Time', 'Recurring') -- submittals with a defined schedule
         and coalesce(s.last_due_date,sysdate) >= sysdate -- only submittals whose last due date has not passed, null last date included
         and trunc(s.first_due_date,'mm') <= to_date('09/01/2012','mm/dd/yyyy') -- only valid start dates
         --and round(round(months_between(to_date('09/01/2012','mm/dd/yyyy'),s.first_due_date))/decode(s.submittal_frequency_months,0,1,s.submittal_frequency_months)) >0
         )
       -- create a list of all potential due dates for these schedules
       select submittal_id_seq.nextval,schedule_Id,8,requires_approval,
       case 
        when recurrence_type='One Time' 
          then first_due_date
        when recurrence_type='Recurring' and trunc(first_due_date)=to_date('09/01/2012','mm/dd/yyyy')
          then first_due_date
        else add_months(first_due_date,(submittal_frequency_months*d.iteration)) 
       end next_due_Date,user,sysdate,user,sysdate
       from schedules cross join (select level iteration from dual connect by level <= (select max(schedules.recurrence_number) from schedules)) d
       where schedules.recurrence_number <=d.iteration
       and 
       trunc(case 
        when recurrence_type='One Time' 
          then first_due_date
        when recurrence_type='Recurring' and trunc(first_due_date)=to_date('09/01/2012','mm/dd/yyyy')
          then first_due_date
        else add_months(first_due_date,(submittal_frequency_months*d.iteration)) end,'mm') = to_date('09/01/2012','mm/dd/yyyy') -- limit the records to the date in question
       and not exists
       (select null from submittal sub
        where sub.schedule_id=schedules.schedule_id
        and trunc(sub.due_date,'mm')=to_date('09/01/2012','mm/dd/yyyy'))
        -- exclude those that already have a submittal record
  ;

  Basically I found all possible records in the table in the annex that could have a record expected in September, and then generate a result for all possible instances and then look at only those whose calculated due date is 01/09/2012. I have determined that the root problem, I have right now is this line:
  
  
  (select level iteration of double connect by level < = (select max (schedules.recurrence_number) of planning)) d
  
  ID of the 469907 planning has a start date of 15/05/1992 and a frequency of all 2 months. I calculate what I call the number of recurrence, i.e. the number of times that the calendar has occurred since its beginning now. I use to make a calculation of add_months from the start date and then finally compare the start dates of these calculated with my month of target (09/12). In this one case records the calculated number of recurrence is 122. Then when I generate the connect by level is 122 records for each schedule, so I end up with duplicate records in the presentation for many schedule table. This current request could probably work if I could find a way to make the specific annex level ID, but I did not that far.
  
  Besides the fact that it returns erroneous results, I think that there must be a better, more efficient method to determine which records are due for a given month. I thought there are probably some great way to use the clause type here, but I don't have a knowledge on that one yet.
  
  If you run the insert statement what follows, you will see that it inserts more than 2,400 records:

  insert into submittal (submittal_id,schedule_id,submittal_status_type_id,requires_approval,due_date,created_by,created_date,modified_by,modified_Date)

  You can see the problem after the words:

  select schedule_id,count(0)
  from submittal
  where trunc(due_date,'mm')=to_date('09/01/2012','mm/dd/yyyy')
  and submittal_status_type_id=8
  having count(0) >1
  group by schedule_id;

  Hello

  I think you want something like Bob solution. To avoid any computation MONTHS_BETWEEN again and again, you can do it once, in a subquery, like this:

  WITH     got_month_num     AS
  (
       SELECT     schedule_id, rec_type, rec_months, first_due_date
       ,     MONTHS_BETWEEN ( TRUNC (SYSDATE,        'MONTH')
                        , TRUNC (first_due_date, 'MONTH')
                        )       AS month_num
       FROM    schedule
  --     WHERE     ...     -- If you need any filtering, put it here
  )
  SELECT     schedule_id, rec_type, rec_months, first_due_date
  ,     ADD_MONTHS (first_due_date, month_num)     AS this_due_date
  ,     FLOOR ((month_num + 1) / rec_months)     AS iteration
  FROM     got_month_num
  WHERE     MOD ( month_num
           , CASE
                 WHEN  rec_type = 'Rec'  THEN  rec_months
                                  ELSE  month_num + 1
             END
           ) = 0
  ;
  

  The WHERE clause in the main query ensures that you will only get results that have a current month end_date.

  Using the sample data that Bob posted, the result is:

  SCHEDULE_ID REC REC_MONTHS FIRST_DUE THIS_DUE_  ITERATION
  ----------- --- ---------- --------- --------- ----------
            4 One          1 16-SEP-12 16-SEP-12          1
  

  Schedule_id = 1 is not due until January and schedule_id = 2 is not due until November.

• Looking for an explanation of the flow of data around a structure of event with data going in and coming out of it

  I am trying to add a case to the structure of the event shown below.  Other cases in the event structure close the front afterwards.  I wish my case in abeyance the façade.  Is it possible to do it with this configuration?

  Because the invoke method is in front of the structure of the event what it means that the Panel should be open whenever the structure of the event begins to look for an event?

  The structure of the event by using the code below, after I pressed the button calibrate stop listening to additional events.  I moved the functions close FP within the structure of the event, so other events he would call here but this does not seem to make a difference.

  Thanks for any help.

  Dave

  

  An event structure only waiting for an event.  To continue waiting for the events after the first occurs, you must put the event structure within a while loop.  Then you can put your knot FP close outside while loop and thread the stop of the while loop condition for the loop stops for the case that you want to close your façade.

  Change the report columns display "Display (escape special characters) text" Type to "Standard report column.

  You can do it, but you must be aware of the security implications that opens upwards (i.e. XSS attacks).

• force the flow of execution

  I'm a newbie has arrived from VEE, so please be patient.

  Vee, I always sequence input pins and output sequence on any bow that allow me to force the execution of a box.

  In labview instead I'm not, so I guess that the execution order is always driven by data, correct them?

  Now, I just created a few local variables where I want to store internal information, so I have the objects in the front panel, and the 'local' connect to them in the chart:

  

  (as you can imagine, I'm changing a complex program, I didn't write it...)

  Now, since these couples: 'Acq length', 'timeIntensity', 'Acq Start time', in whole isn't all input/output, I don't see how to impose their execution. In fact, they are never executed...

  what I am doing wrong? Thank you for your help...

  Thanks for the suggestion...

  I am already tracking at least 3 manuals/tutorials in parallel,

  but nowhere I found an answer to this question.

  From what I've seen (Please correct if I am wrong), the execution goes according to:

  (1) the data flow

  (2) the error in / error on pins

  ... Since my case is not available, I'm really at a loss to know what to do.

  P.S. just in case my using local variables deemed not necessary: I transfer data using son whenever that is possible, but in this case I use inhabitants because I set a few values within a species a case structure, and I do use them in another case.

  If the transfer of data by wires between the cases is possible, I will be happy to hear!

  Alessandro

  You are on the right track, except that the error in and out is just another example of data flow.

  LabVIEW data flow can be summarized in two sentences:

  A node will not run as long as all entries are filled.

  A node will not produce output until the node has executed completely.

  When you boil everything down to basics, those are the only things that determine the flow of data.  If you take these two instructions literally, all cases where it seems that the execution order is ambiguous are really ambiguous - and you'd better fix it if a node is run before the other.

  It's really a case of 'easier said than done. "

• the relay control data acquisition

  I am creating a vi that controls (press and release) several relay using a USB 6501 data acquisition. This should be a task relativily easy but I get flumoxed by errors. I tried to use the examples, but I get an error telling me that I need to use the mode of generation 1 sample (on request). Help, please

  Sure. The easiest way is to have a DAQmx writing followed by a function of delay, followed by another entry, followed by another period. Simply plug the error links in order to control the flow of data. However, the VI would be insensitive so you can use a state machine or function elapsed time so that the VI can be stopped without waiting for waiting for him at the end.

• Reset on FF ver 26 remove all client connections FTP FF, the recovery of the old FF data folder?

  My FF browser was weird, so I did a Reset. My whole FF Ftp program has been removed. I installed the addon FF Ftp after the reset. I need to know how to return the file fireFTPsites.dat from the folder "Old data Firefox" browser worm FF 26. I have the latest version of FF on my windows xp desktop.

  Unfortunately, I don't have a master list of my client user ftp & pws.

  I am a novice. I read everything that in the Support section and really need help on how to get ftp info in the folder of old data from FF and get this info usable FTP again. Thank you.

  I think you should copy these 3 files from your old profile folder to the current.

  • fireFTPsites.dat
  • signons3.txt
  • signons.SQLite

  The second and third files are your saved passwords. Note that replace your current signons3.txt and signons.sqlite files will replace any password that you have registered in your profile.

  To open your active profile folder, you can use either:

  • Help > troubleshooting information
  • type or paste everything: in the address bar and press Enter

  Then in the first table, click on the view file"" button. Keep this folder open, switch to Firefox and the output.

  Copy the 3 files from the old profile on your desktop folder in your new folder. Make sure that you do not copy the other way, for obvious reasons!

  Then restart Firefox. Success?

• Questions about to determine the size of the array of data storage with flexibility

  I try to use the CVI function below to load data from .csv file to the table that I was intending to use later:

  filereturnvalue = FileSelectPopup ("c:\\Users\\Desktop\\FileDirectory", "*.csv", "", 'Select the data file', VAL_LOAD_BUTTON, 0, 0, 1, 0, LoadFilePath);

  FileToArray (DATAArray, VAL_CHAR, LoadFilePath, MaxDataSize, 1, VAL_GROUPS_TOGETHER, VAL_GROUPS_AS_COLUMNS, VAL_ASCII);

  For the data table "predetermined", it is quite straightforward, because the size of the table is already set.  However, I wonder if there is anyway I could use CVI directly import data and determine the size of the array on the fly?  Which means that the user need not know the length of the data, and it could be determined then to import the file.

  Hello

  for ASCII files, you can do so in any first read the file and counting the newline characters, something like:

  int file_handle;
  int index;
  int size = 0;
  char line_buffer [80];

  If (OpenFile (...) > 0)
  {
  While (ReadLine (...) > 0)
  {
  size ++;
  }
  }
  CloseFile(f) (file_handle);

  This way you can determine the number of rows you have, but you must have an idea of how long a line may be, one number per line or 32000 because you must specify the size of your line_buffer.

  In the next step you analyserions monotube for occurrence of your column separator (say a ;) to determine the number of columns (separators found + 1).
