• build the table by concatenating berries 2

  Greetings,

  I have the need to combine tables 1 d (Qty 2) to TestStand for the first time each. They both will always be the same size. I would build by concatenating.

  Table 1 (String): some number 1, some number2, some Number3

  Table 2 (string): string description1, description2 string, string description3

  Output array: some number 1 string description1, some number 2 string description2, some Number3 string description3 (so it would be total 3 items)

  Thanks in advance for any help.

  Chazzzmd

  Hello

  You can concatenate 2 strings in TestStand using the operator ' + '.

  Example:

  Locals.Output = Locals.String1 + "" + Locals.String2

  Concatenate individual pieces of the string into arrays of strings, an easy approach would be to use a loop structure to browse table and concatenate all of them. Please find below a sequence file simple (I created it in 2010 TestStand) it does using the "For Each" as well as "Looping" property loop structure within the parameters of the step. I hope this helps you.

• Concatenation FDM Import Table script

  Hi all

  First post here, so let me know if I'm making mistakes or leaving out critical information.  I'm trying to use FDM for importing a pipe delimited text file, use the mapping feature, and then export the new data to a .txt file.  The problem is that the entity on the finished side dimension must be a concatenation of the fields of the entity and the division.  What I tried to do is to write a script for the field of the entity on the tables import screen.

  Function Div_Ent_Comb (lngCatKey, dblPerKey, strLoc, strWorkTableName)

  '------------------------------------------------------------------

  "Integration oracle Hyperion FDM IMPORT script:

  '

  "Created by: cwinslow"

  "Creation date: 2014-10-09 15:34:39.

  '

  ' Object:

  '

  '------------------------------------------------------------------

  'Set variables '.

  Dim strCombination As String

  Dim strDivision As String

  Dim strEntity As String

  ' set where the combo will go

  strCombination = Trim (DW. Utilities.fParseString(strRecord, 29, 8, "|"))

  "Store column 7 of 11 of a delimited file

  strDivision = Trim (DW. Utilities.fParseString(strRecord, 29, 5, "|"))

  "To store the column 8 of the 11 of a delimited file

  strEntity = Trim (DW. Utilities.fParseString(strRecord, 29, 8, "|"))

  strCombination = strDivision & strEntity

  End If

  End Function

  Error when importing is as follows:

  Error: An error occurred importing the file.

  Detail: Object Variable or With block variable not set

  What I want to happen is when I import the file, is for the entity column show the result of the concatenation before going through the validation part.

  If you're just trying to concatenate two fields to use as a source for a mapping for the entity dimension, there is a much easier way to do this without script. In your import format to create two entries for the target dimension i.e. entity. The first line contains a reference to the field of the entity of your source (data field 8 of 29), the 2nd line will contain the reference to the field of the Division of your source (data field 5 of 29). If you do this FDM will automatically concatenate the 2 fields together for you.

• Reset table to allow the continuous addition

  Hello

  I am writing a program that collects the data and returns an array with each iteration of a loop For.

  The berries are concatenated into a larger painting.

  Then the big Board grows with each iteration of the loop For.

  Now, I found that if I call my program several times without leaving LabVIEW, the new implementation adds the table again to the former.

  This happens even if I specify a new file to write apparently, the table is never recovered and remains in memory even after I have stop running.

  I tried "Reset Array" on the forum, but in this case I don't want to just re - initialize, I want to eliminate any value in this table.

  Can someone help me with this?

  I'm relatively new to LabVIEW.

  Thank you very much

  Nicolas

  Simply right click on the left edge of the left shift register and select "create constant. Voila!

  (This will automatically create a constant of the correct type, in this case an empty a 1 d array of strings)

• subset of table truncate the end of the 2d array

  The intention was to make a program that would generate asynchronous several different signals in a buffer.  Then something would consume the buffer - an output daq, and signal processing.  I created a dummy consumption which takes only 1% over the beginning of the buffer.  Whenever the buffer is smaller than the specified size, more signal will be added at the end.

  I ran into a problem where the function of the subset of the Array is truncate the end of the subset sometimes, so I disassembled the program until a congruent portion of the code exists to cause the problem.  It seems to be the use of memory or related allowance.  Maybe I'm doing something that I shouldn't be, but it seems like a bug in labview.  In the block diagram, I have a note that shows a waveform wire that goes to a case statement.  Just remove this thread causes it to work properly as seen by the consistency of the waveform on the front panel.

  I'm using Labview 2014 (without SP1)

  I would be grateful for any ideas.

  To work around the problem, use the copy always at the moment. I'll try to engage someone R & D of LabVIEW to get the last word.

  In any case, it seems unnecessary to carry all these t0 (which is always zero!) and dt (which is always the same. Constantly from waveforms to bays and back just really clutters the code. If dt would be different between the waveforms, you would have a much bigger problem .

  I understand that your actual code is much more complicated and what you show is just the tip of the iceberg lettuce.

  Here is a general overview of execution project ideas.

  • Use 'building the table' (concatenation mode) instead of "insert into array. It's cleaner.
  • Use simpler and easier to read the code to find the size of the table smaller
  • Only use tables. You can define once and dt for all graphs.
  • Use the correct representation for buffer size controls.
  • Don't place unnecessary sequence structures.
  • I don't think that you really need that local variables, the terminal is written often enough (stops you extra copy of the immense tables in memory!)
  • Do not know what is the structure of matter, but I left it in for now.
  • Add conditionally empty bays, just wire the table via unchanged instead.

• size of a table in an access database

  Hello

  I try to know the size of a table in the access database, then I would be to turn it into a string value, but I have no success.

  I have attached a JPEG of my code.

  in the concatenated string should appear "rapportx.png" where x represents the size of the table

  You must use 'Decimal string' to convert the number to text.

  Please also note that the size "Array" returns a 2D array in your case: If you have two dimensions.

  Finally, and above all, to count the number of records it reveal be more efficient to use the sql count() function:

• String concatenation without loop

  Hello

  I have an array of strings containing numbers in engineering as format below:

  5.34000E - 10

  3.23245E - 1

  -8.43560E - 9

  I'm trying to concatenate to this array of strings to a header, which is a unique, formed string using the string concatenation function.  So, I would that my output as follows:

  Header line 1

  Header line 2

  Row header 3

  5.34000E - 10

  3.23245E - 1

  -8.43560E - 9

  However, the result is currently reads:

  Header line 1

  Header line 2

  Row header 3

  5.34000E - 103.23245E - 1 - 8.43560E - 9

  I can get the desired result using a loop for, but I do not like concatenate them strings function seems to run very slowly in the loop.  Is there a way I can get the desired result without using a loop for?

  Thank you.

  It is a real possibility that concatenate strings runs slowly in a loop For. change the statement "I find that Array Build runs slowly in a for loop" and we would get a serious discussion of fly memory. Absolutely no difference here, maybe even worse because the strings are more difficult to predict than most data types. There is perhaps not a miracle solution to make it faster, but there might be ways to ensure there are no longer than necessary. I probably just build the header as its own array of channels and build table allows to reach the two (concatenate entries of course). Writing to text file will manage an array of strings directly when the time comes.

• concatenate the bunches to the table with enums

  Hi I'm trying to concatenate three tables 1 d filled an i32 and an enum.

  When I look at my table concatenated, I lose my enum information... It is 0,1,2,3,4 etc. instead of the channel names?

  

  Does anyone have a solution for this?

  Best regards

  Thijs

  How exactly did you 'look' table concatenated? If you use a digital indicator instead of listed, the VI will run, but you will lose the enum names.

  However, if you the probe wire, and/or right click > create indicator... you should not encounter the problem, in which case the problem must be somewhere else.

  In other words, the entry of a table should be converted into a data type similar to an entry in a zone of control of chain... I went through some of the forums and discussions, I quite couldn't understand exactly how the conversion is made...

  Thank you

  I agree with crows that is not not clear at all what you want. To convert an array of strings into a single string, simply use the string concatenation.

  

  If the string must have separators, use "table to a spreadsheet string.

• Adds data to the binary file as concatenated array

  Hello

  I have a problem that can has been discussed several times, but I don't have a clear answer.

  Normally I have devices that produce 2D image tables. I have send them to collection of loop with a queue and then index in the form of a 3D Board and in the end save the binary file.

  It works very well. But I'm starting to struggle with problems of memory, when the number of these images exceeds more than that. 2000.

  So I try to enjoy the fast SSD drive and record images in bulk (eg. 300) in binary file.

  In the diagram attached, where I am simulating the camera with some files before reading. The program works well, but when I try to open the new file in the secondary schema, I see only the first 300 images (in this case).

  I read on the forum, I have to adjust the number of like -1 in reading binary file and then I can read data from the cluster of tables. It is not very good for me, because I need to work with the data with Matlab and I would like to have the same format as before (for example table 3D - 320 x 240 x 4000). Is it possible to add 3D table to the existing as concatenated file?

  I hope it makes sense :-)

  Thank you

  • Good to simulate the creation of the Image using a table of random numbers 2D!  Always good to model the real problem (e/s files) without "complicating details" (manipulation of the camera).
  • Good use of the producer/consumer in LT_Save.  Do you know the sentinels?  You only need a single queue, the queue of data, sending to a table of data for the consumer.  When the producer quits (because the stop button is pushed), it places an empty array (you can just right click on the entry for the item and choose "Create Constant").  In the consumer, when you dequeue, test to see if you have an empty array.  If you do, stop the loop of consumption and the output queue (since you know that the producer has already stopped and you have stopped, too).
  • I'm not sure what you're trying to do in the File_Read_3D routine, but I'll tell you 'it's fake  So, let's analyze the situation.  Somehow, your two routines form a producer/consumer 'pair' - LT_Save 'product' a file of tables 3D (for most of 300 pages, unless it's the grand finale of data) and file_read_3D "consume" them and "do something", still somewhat ill-defined.  Yes you pourrait (and perhaps should) merge these two routines in a unique "Simulator".  Here's what I mean:

  

  This is taken directly from your code.  I replaced the button 'stop' queue with code of Sentinel (which I won't), and added a ' tail ', Sim file, to simulate writing these data in a file (it also use a sentinel).

  Your existing code of producer puts unique 2D arrays in the queue of data.  This routine their fate and "builds" up to 300 of them at a time before 'doing something with them', in your code, writing to a file, here, this simulation by writing to a queue of 3D Sim file.  Let's look at the first 'easy' case, where we get all of the 300 items.  The loop For ends, turning a 3D Board composed of 300 paintings 2D, we simply enqueue in our Sim file, our simulated.  You may notice that there is an empty array? function (which, in this case, is never true, always False) whose value is reversed (to be always true) and connected to a conditional indexation Tunnel Terminal.  The reason for this strange logic will become clear in the next paragraph.

  Now consider what happens when you press the button stop then your left (not shown) producer.  As we use sentries, he places an empty 2D array.  Well, we dequeue it and detect it with the 'Empty table?' feature, which allows us to do three things: stop at the beginning of the loop, stop adding the empty table at the exit Tunnel of indexing using the conditional Terminal (empty array = True, Negate changes to False, then the empty table is not added to the range) , and it also cause all loop to exit.  What happens when get out us the whole loop?  Well, we're done with the queue of data, to set free us.  We know also that we queued last 'good' data in the queue of the Sim queue, so create us a Sentinel (empty 3D table) and queue for the file to-be-developed Sim consumer loop.

  Now, here is where you come from it.  Write this final consumer loop.  Should be pretty simple - you Dequeue, and if you don't have a table empty 3D, you do the following:

  • Your table consists of Images 2D N (up to 300).  In a single loop, extract you each image and do what you want to do with it (view, save to file, etc.).  Note that if you write a sub - VI, called "process an Image" which takes a 2D array and done something with it, you will be "declutter" your code by "in order to hide the details.
  • If you don't have you had an empty array, you simply exit the while loop and release the queue of the Sim file.

  OK, now translate this file.  You're offshore for a good start by writing your file with the size of the table headers, which means that if you read a file into a 3D chart, you will have a 3D Board (as you did in the consumer of the Sim file) and can perform the same treatment as above.  All you have to worry is the Sentinel - how do you know when you have reached the end of the file?  I'm sure you can understand this, if you do not already know...

  PS - you should know that the code snippet I posted is not 'properly' born both everything.  I pasted in fact about 6 versions here, as I continued to find errors that I wrote the description of yourself (like forgetting the function 'No' in the conditional terminal).  This illustrates the virtue of written Documentation-"slow you down", did you examine your code, and say you "Oops, I forgot to...» »

• Rotate several tables of channels 1 d

  Hello

  I have a vi that eventually writes some data to a log (.txt) file.  In the data that are written, there are a few tables.  In a particular section, I have three arrays of strings that I try to handle it with no luck.  Here is an example of what I have now, and subsequently, where I want to be:

  Present:

  x 1

  x 2

  x 3

  Y1

  Y2

  Y3

  Z1

  Z2

  Z3

  Desire:

  x 1 y1 z1

  x 2 y2 z2

  x 3 y3 z3

  Where x, y and z represent the three tables of sepreate channels.  These tables is then concatenated with other data to generate the log file.  It seems that no matter what I do (build, transpose, index, etc...) I still end up with the vertical arrangement in my log file - I'm sure I'm overlokking something trivial, but it's deceiving me right now.

  I cannot post my code because of security, but will provide any more detais needed.  Thanks in advance.

  I think you are looking to do a table build followed by a transposition.

  Your build array must have 3 entries.

  Feed it to X, Y and Z and you should get

  x 1, x 2, x 3

  Y1, y2, y3

  Z1, z2, z3

  Hit this result with the conversion and you should get

  x 1 y1 z1

  x 2 y2 z2

  x 3 y3 z3

  What do you use to write to the log file?
