A loop makes me Loopy!

• Loop makes me crazy

  New at EA and I've seen several tutorials on this subject:

  I have an animation set to auto play with several symbols nested all the same exact length in time. I tried to define an action to 'play' at the end of the timeline, but nothing happens. I also tried setting the shutter to 'play' on the symbols themselves, but nothing happens. I'm going crazy.

  You need a sym.play(1000) trigger (0) at the end of each of the five slide show time, if indeed you want to that they simultaneously loop inside your main symbol.

  Decomposition in symbols is not a question of efficiency, but to structure your project. Everything in the scene (in Edge animate, the scene is itself a symbol, so your main symbol is useless) would lead to a huge stack of items in unique mounting Panel: much harder to read and maintain.

• DIO using loop to generate TTL

  Hello

  I have a sbRio and on the FPGA, I have a loop that runs every 5 US. The loop has a counter that increments with each iteration, and I acquire analog data each cycle (effectively setting the rate to 200kS/s). The counter is used to generate a Boolean value True or False. Thus, for example, if the count is less than 200 (for example) the value is False, but greater than 200, it's true. The counter then resets back to zero in, say, 400. This counter is used for two purposes - the resulting value of T/F is sent to a DIO port then it becomes, in effect, a TTL output, and because I store the meter with the analog data, it acts as a reference for where the data were sampled in the cycle TTL.

  My problem is that when I look at the output "TTL" on an oscilloscope everything seems pretty OK... except that now and then I get a glitch where it suddenly either falls to zero or "stutters".

  The question I have is this - if I write a True value for a port DIO in a timed, loop makes this "lock" of value until it is changed or does literally flick on then turned off during a period of time (the implication being that it is actually not a true continuous, but a series of true/false steps which occur on a timescale much shorter than my loop time)? If so, is there a way to make sure the value remains constant until the next iteration of the loop? If this isn't the case, then should I move using ticks rather than at the loop timer?

  Thanks (and sorry for the length).

  I think the question is read the values half/full cycle. If I replace those with constants, the problem seems to disappear. I moved the reading of those outside the main loop, and that seems to have worked.

  Thanks for your help! The loop of the case has been deleted since, as you pointed out, it was not necessary. Oh and sorry for the twisted...

  I used the above structure at length in many functions and procedures of all associated with an application and works very well. However, I began to review my code and I thought he might be better way to do it. One of the methods I've found is cursor for loop: http://www.techonthenet.com/oracle/loops/cursor_for.php

  and http://docs.oracle.com/cd/E11882_01/appdev.112/e25519/cursor_for_loop_statement.htm#LNPLS1155

  I'm trying to understand the advantages and disadvantages of each method. I get the following (rating my approach is, and cursor for loop is B

  (1) A is faster because it uses in BULK COLLECT IN as opposed to B which is implicitly opens, fetch a row and close each round loop.

  (2) A is a bit messy, a lot more code as opposed to B which is readable, ranger.

  First of all, I would like to know, if my conclusions are correct or not?

  Second, what other differences might be between the two?

  Third, is there another approach, that I'm not aware? Or what improvement could be applied to my approach, if there is?

  Yes, I did. Executable statements are most HTTP POST and PUT request that write in MongoDB on a platform that does not write in BULK. So I have to write one record per HTTP request.

  Then pass PL/SQL to run multipe HTTP put and recorded at the same time. In which case manual removal bulk buys you no performance gain and zero scalability.

  Use DBMS_PARALLEL_EXECUTE to chunk the workload. Execute each thread (parallel work process) using a standard FOR cursor loop (for example for loop in(select...) end of loop; c...) --and inside the loop, make HTTP calls.

  When I set the exception inside the loop, as above, the procedure seems never to end, and I end up getting a 'NOWAIT' error when I try to remove the table or something like that.

  The code works fine if I remove the 'START' just after the loop and also out of the exception within the loop, but I want to be able to specify what's wrong with each record rather than deal with the correct records and then stop after that it is a record that has, for example, 9 values in a column that accepts only 6.

  Can anyone help with this?

• How to remove columns from the table on the master 1-0?

  I have an array of 96 columns with strings. I also have the array of int 96-elemets (mask) with 1 and 0.

  What I want to do is to is to remove (or hide - but I read that it is not possible) all the columns with index corresponding to 0 in the mask table.

  example:

  columns in the table

  1 2 3 4 5

  mask

  0 1 0 0 1

  I want to remove the columns 1, 3 and 4 and leave only 2 and 5 in my table.

  How can I do?

  If I create loop for with i as the index of the column, when I do DeleteTableColumns() columns number decreases, and I get an error of range out of

  Or do I have an option to hide the unnecessary columns (not set their width to 1, it's very ugly-looking)?

  Please help me (())

  Hello rovnyart!

  1. removal of columns in the table:

  I suspect that the reason why you get the out-of-range error is due to fact that in your loop, you delete the columns in the table, you'll eventually end up by referring to a column that no longer exists, because the other columns before it have been deleted. While you remove each column of your table in the loop for example, the column index number will move, because you deleted the other columns in front of her.

  To resolve this, even if you delete a column in your loop, make sure that you take also into account that the index of the column is moved because of the removed columns.

  2 hide columns in table:

  You can use the ATTR_COLUMN_VISIBLE attribute to hide columns in the table:

  http://zone.NI.com/reference/en-XX/help/370051Y-01/CVI/uiref/cviattrcolumnvisible_column/

  3 alternatives:

  Note that another alternative would also use a tree instead, control as the tree control also supports the hidable columns:

• Help with oscilloscope Agilent 54810 A data recording

  I use an Agilent 54810 A oscilloscope with GPIB interface, I can't save the voltage (y-axis) and data(x axis) of the time together. I can only record time data.

  could you please help, I would like to save the data to a text file.

  I don't know why you say that you are only able to save the time data. What you save is the data. If you want to use scripture to measure file, create a waveform based on data type of Y and x increment that you receive from the wave function of reading. You simply use the wave function build for it (inside the loop).

  With a constant True not wired to the GOLD from inside everything in fact point of termination of the loop makes no sense. Might as well not have while loop. With a single iteration, I understand not also the purpose of the exit of the auto-index in a 2D array.

• To find screws with front panels open to a project!

  How do you find the screws with facades open, which were launched from within a project?

  (See attached image).

  Maybe it's something you could do. In the path of project control, use a path to the project that you want to test against. Within the loop, make sure to transfer the reference of the VI primitive Open reference applications.

  Within the loop, it tests only whether the FP Panel is open. This means that the output array could end up with including ctl/Globals/Broken screws also. If you want to filter those out, you could add another VI as VIType property to test whether the item is something you want to include.

  I hope that helps!

• How to read the txt file that has words in between?

  Hi all

  I'm using Labview 8.2.

  I would like to read a text file.  I have given (after whenever he was on average more than 100 waveforms) several times recorded on the file.  The idea is to further improve the SNR in post processing by averaging once again the data (which was on average about 100 wave forms).

  I can get LabView to save the data in the file several times, then it keeps joins.

  The problem is to read data from labview, so I can on average now again.  The problem is the labview separates data sets with the following:

  "Channel 1".
  9925 samples
  Date 28/10/2008
  Time 17:16:11.638363
  X_Dimension time
  X 0 - 3.0125000000000013E - 3
  Delta_X 2.500000E - 6
  "End_of_Header."

  Then when I read it, he sees only the first set of data.

  Can someone tell me please how to read all the datasets under labview?

  I am attaching the file I want to read 'acquiredwaveform.txt' and the VI base (really basic btw) to play the file.

  Thank you

  This seems to be a standard LVM-file.  You can read segments of different data using the VI Express LVM loop (make sure that the file retains its extension .lvm).  I modified your example to show this.

  Note that my example is quite inefficient. Table of primitive construction causes a massive memory copy whenever it is used, and you would be probably better on average that you read in.  I made this way to make it more obvious how read segments of a file LVM.  In the process, I noticed that you have a good amount of phase jitter (zoom in on the graph of all the three waveforms).  With an average simple will make you smear on your waveforms.  You can either fix the problem in hardware (recommended) or phase shift your data so it lines up before on average.  If you need help with it, let us know.

  Hello!

  In the file attacched, I write a table using loop1. In the loop2 2 I build an array of arrays, but im not able to link the two loops to add a new table to table every time 2 loop in loop change 1.

  Any suggestion?

  At the present time, but the curls are run independently and there is no guarantee that the loop 2 wait until new data has been produced in loop 1. Your second loop makes no sense. He simpliy duplicates the current data 100 times.

  The correct way to proceed is by using a queue. Here is a very quick project on how to deal with table 1 d in the second loop, whenever new data were obtained.

  

  You still need to add error handling and the code for the calculation of the average. Most likely, you want to initialize the shift with a fixed array size 2D register according to the desired number of averages and then replace the oldest line on each before call on average. See how far you get and ask again if you get stuck.

• LabVIEW imaq flickering image

  Hello!

  My name i s Andreas and I have problem with flickering images on the screen. I tried to use the snapshot without success. I also read that you can use the node property erase images first, but the thing I have is it impossible to use because it says that

  the property is not valid for this class. the display gets imaqimages. I have to convert the images it's supports the property?

  I have attaced the file below. The screen is in the loop in order to data.

  Hello

  A proposal without the full code I guess you are the flickering image thresholding. Images works slightly differently to most cables in LabVIEW. The value on the wire is a reference to the image so that we do not round huge chunks of data. Outside of your loops, make sure to create an image for the eachstage of your image processing. Each VI Vision that you use which has a destination image must have that cable to the corresponding image you have created outside of the loop.

  The display Gets the mapping to the memory segment that has the image in it. If the picture changes then made the display. If you change the image through many operations of the display, flickers.

  Try and see if it solves the problem, if not you will have to publish the project as a whole, then we can see what is happening in the subVIs.

• How to use DBMS_PARALLEL_EXECUTE with CURSOR

  I write data from Oracle database MongoDB via http calls (POST, PUT). Data is changing and I'm entering it via a slider and then inside the loop for example, I make the call http (appealed by iteration). MongoDb does not write in bulk, so I have to send one line per iteration. It takes a lot of time (for example, 30 minutes to write 3 K lines).

  Inspired by the answer to this question that I figured out that the process can be more effective with the help of DBMS_PARALLEL_EXECUTE. However, this part "run each thread (parallel work process) using a standard FOR cursor loop (for example for in(select...)). c loop... end loop; )- and inside the loop, make HTTP calls" is not not clear to me."

  I have the following syntax:

  FOR c IN
            (SELECT......)
  LOOP
            --http calls
  END LOOP;)
  
  

  
  

  I tried to read the examples here , but I couldn't understand the following:

  • Based on what I should create pieces in my case (ROWID, collar number or SQL)?
  • Where should I create task? At the beginning of my procedure? Inside the loop? And where I create pieces? Inside the loop?
  • What about DBMS_PARALLEL_EXECUTE.run_task?
  • What is the size of chunck? I understand that I can open only 5 max http calls at the same time

  Your help is very appreciated.

  P.S. I preferred to open the new thread, as the discussion will be on DBMS_PARALLEL_EXECUTE instead of the sliders of best practices.

  Yes, you can not chunk a cursor (compiled and analyzed SQL).

  You need for the block using a SQL (SQL source code). And this SQL must return the piece ranges using custom logic.

  If a table must be stored in a block or a SQL statement must provide the pieces. A cursor cannot be chunked, as Oracle has absolutely no idea that the lines will be processed by the slider - what is discovered only when the cursor is running and running and looking for lines. And by then, the process is already running and cannot be transformed into a parallel process.

  In other words, the workload must be known, to chunk this workload - it break up in smaller workloads. A cursor represents an unknown work load. How many rows will be treated? Unknown until the cursor runs and made search lines to deal with. An unknown work load can be stored in a block.

• divide the text in paragraph format

  I came across a scenario where I have to pull the value of database table column whose datatype is clob.

  This column contains descriptive information. Here I have to publish data in the format of paragraph to comply with the conditions

  No line exceed 80 characters maximum, no words are cut between the two to start the new line.

  Example of

  If I limit myself is by line 4 char

  then separated from the text abcd ef ghi jkl mn opqr

  Power required is

  ABCD

  EF

  IGS

  JKL

  MN

  opqr

  In addition, if solutions comes from regexp that guide/document/link is recommended for this.

  Some examples of my library of examples:

• Commas in cause of importing CSV values

  I'm having a problem with my code only inports and analysis via a CSV fault if there is a comma in the value of a column.

  Is there a way to distinguish between a comma between a column and a comma that is in the value of the column?

  The code below works fine except if there is a comma within a value (which does not exist in the CHY_NAME value).

  What happens is, for example:

  IF:

  CHY_NAME = Hello, it

  UPDATED_BY = me

  When the data are asked in the table:

  CHY_NAME = Hello

  UPDATED_BY = y

  I noticed that when in excel, if you type something in a column that has a column he puts quotes around him ("Hello There")

  In the line of code that says:

  v_line := REPLACE (v_line, ',', ':');
  
  

  Is it possible to write it as:

  v_line := REPLACE (v_line, ',', ':')
       where v_line not like '%"%,%"%'
  
  

  Or is there a better way to ignore commas between quotation marks?

  Thank you

• How to sort the list alphabetically using #listgetat? more details in the post

  I have pictures in the site, but it seems to pull them from the most recent added, is possible to shoot in alphabetical order by file name?

  I'm not too experienced with CF, but I'm good with HTML/CSS, trying to fix some things on a friends because of a rampant backend developer site.

  Sorry if this does not have too much sense.

  That's what it looks like now

  < div >

  < img width = "920" height = "300" src = "images / data / < cfoutput > #ListGetAt (pic 1)" # < / cfoutput > "/ >"

  < / div >

  < div >

  < img width = "920" height = "300" src = "images / data / < cfoutput > #ListGetAt (pic 2)" # < / cfoutput > "/ >"

  < / div >

  ...

  Before first use of your list, convert it to a table using ListToArray(), then do an ArraySort() on it.  I consider also replace your code with a loop makes a loop on your list or a table and adds the

  and items.  Then, you can host any number of images in a more dynamic way.

  
  
       
  
            
                 If the photo names upper and lowercase and you want case insensitive sort, simply change 'text' to 'textnocase' in line 1 above.
