• How to convert binary data from the Panel controls in ASCII values?

  Hello

  I seemed to face a roadblock with how to convert binary values in ascii.

  I created this .vi to save all control values in an .ini file and call them at that time where I will carry out the .vi as shown in the file attached. Registration key to simply save the data and Cancel button discards all current changes.

  I would like to understand how to retrieve all the values of control to ASCII, so I assign to a global variable for later use. I've looked everywhere for a good reference document, and I couldn't find one that would explain my question. I would be greatly appreciated if someone could point me in the right direction.

  Thank you

  I tried a simple way to save control values in the front panel

  Not reinventing the wheel, when there are ready to use of solutions, for example:

  Use the MGI save & restore settings VI of the palette (for example, it records all the settings that have been changed in a graph, which is very useful) and the MGI Save (restoration) Front Panel data live (to save and restore control values in the front panel).

• How to convert binary data NVARCHAR2?

  Hi all

  I have binary data in the database (RAW oracle data type). I know that these data contain string encoded in UTF8. Our database runs in WE8ISO8859P15 encoding, UTF8 national character set. Then I would just convert the binary data NVARCHAR2. How can I do?

  I found the UTL_RAW function. CAST_TO_NVARCHAR2. However, this function takes only binary data as a parameter, so I highly doubt that it will work as I hope without specification of source character set...

  Someone has an idea?

• don't read full of binary data from the db

  I have a strange problem. I read the binary data (png images) of database through cold fusion. everything worked, but now it has stopped working. the exact same script works on another server and the images appear correctly. but on the other server, it works more (from one hour to the next..). data base is the same. other data in the database are correctly read. but binary data may not be read or not completely. images remain blank, because only a header is created.
  I managed to convert the binary data, which are read for string and display it on both servers. Result, on one server, its site more of one and a half on the non working server, it's just more or less an information line.
  any ideas what could be the problem? kind of time-out due to the length of the data?
  
  

  do not know how and why, but after 5 days of research, and now, writing this post, I looked in cold fusion administrator and I saw, that the ' enable binary large object (BLOB) retrieval ' has been disabled... it wasn't me...
  so the problem is solved

• How to convert string data from the serial port to double?

  Hello!

  I am very new in LabView and attempt to read data from an OHAUS pioneer pa-313 electronic scale via RS232 serial port. I use the VISA.

• Handling of binary data (TCP/IP)

  Hello

  I was wondering if someone could point me in the right direction of processing continuous data TCP/IP and more meaningful information. Data contains 'an array of 10 tanks. For the sake of the argument, I saved some data in a text file. I tried to use the typecasting and unflatten to the chain function to convert the data to ascii in real time, but my lack of knowledge with the conversion of binary data makes it very difficult.

  Luckily, I got to convert binary data stored in a table of numbers of single precision that displaying the correct values. However, I am still confused in doing so in real time. I have attached all of the data and the example vi.

  Thank you

  Sam

  After hours of searching on forms.ni.com and I was able to convert table 10 floating point values readable in LV values as drjdpowell has pointed out that using modern "Unflatten chain" is much easier to accomplish this task. Because I had to deal with the old version of LV (7.1), I had to use cataloged with loop I32 array type, For, Swap, Swap bytes words and catalogued with array type SGL. Please refer to join .vi for more details.

• 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...

  Bob Schor

  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...» »

• Import csv into Apex with the only time data.

  Hello

  I tried to understand this question for awhile now and have been on several forums without success.

  IM learning SQL and PL/SQL, so please be gentle

  I am in charge of a csv file, where the data is time in the "KO_TIME" column for example 13:30 'or 18:00 ' 24 hours just hours and minutes.

  I am aware of the TO_CHAR function to convert a date to a string in an insert statement, but I want to be part of the creation of the table syntax, so I'm able to use the Import CSV APEX tool and it will include the time format data 00:00.

  The creation of the table is so far, but with syntax errors;

  CREATE TABLE  "FOOT_BALL_VENUES" 
     (     "ID" NUMBER, 
       "DESCRIPTION" VARCHAR2(30), 
       "DAY" VARCHAR2(30), 
       "DATE_FIX" DATE, 
       "KO_TIME" DATE AS (TO_CHAR('HH24:MM') 
                  "FIXTURE" VARCHAR2(255), 
       CONSTRAINT "FOOT_BALL_VENUES_PK" PRIMARY KEY ("ID") ENABLE
     )
  /
  
  CREATE OR REPLACE TRIGGER  "bi_FOOT_BALL_VENUES" 
    before insert on "
   
  FOOT_BALL_VENUES"        
    for each row 
  begin  
    if :new."ID" is null then
      select "FOOT_BALL_VENUES_SEQ".nextval into :new."ID" from dual;
    end if;
  end;
   
  /
  ALTER TRIGGER  "bi_FOOT_BALL_VENUES" ENABLE
  /
  

  Thanks for your time guys.

  Hello

  If your KO_TIME csv column have alone time, then use the data type VARCHAR2 to your column of table KO_TIME.

  If KO_TIME csv column have the date and time, and then use the DATE format and for example create the virtual column that shows the only time.

  CREATE TABLE  "FOOT_BALL_VENUES"
     (     "ID" NUMBER,
       "DESCRIPTION" VARCHAR2(30),
       "DAY" VARCHAR2(30),
       "DATE_FIX" DATE,
       "KO_TIME" DATE,
       "KO_ONLY_TIME" VARCHAR2(255) GENERATED ALWAYS AS (TRIM(TO_CHAR(KO_TIME,'HH24:MI'))) VIRTUAL,
       "FIXTURE" VARCHAR2(255),
       CONSTRAINT "FOOT_BALL_VENUES_PK" PRIMARY KEY ("ID") ENABLE

• convert the data in the table to mix cases

  Hi all
  
  I have a table that contains data.
  This table has columns, id, and description.
  
  I want to update my table to convert data to toss the case.
  From now on, all my data in the table are tiny.
  
  What I mean when mixed is the first letter of each word is capitalized and the rest lowercase.
  is there a function I can use?
  
  example:
  

  Amended/Resentence, Type Unknown

  Thank you

  You can use the INITCAP function.

  update table
  set description = INITCAP(description);
  

  Example:

  create table test (description varchar(50));
  
  Table created
  
  insert into test values ('amended/resentence, type unknown');
  
  1 row inserted
  
  select * from test;
  
  DESCRIPTION
  --------------------------------------------------
  amended/resentence, type unknown
  
  update test set description = initcap(description);
  
  1 row updated
  
  select * from test;

  but by using the parse method in SimpleDateFormat class can get the result format java.util.date...
  and also using method format may result in the conversion of strings...

• Converts a date into a date/time object string

  I have a JDBC call to enter data, including a date/time stamp.  For the life of me, I can't understand how to convert this string to a date/time field correct.  It is important, because I need to use validation strings to present a time more simplified users on a form.  But I like to keep the original date/time, so I can insert it again into a SQL db at the end.  I created a test process, so I can watch the progress.

  
  ' input string = ' 18/08/2010 16:41:23.

  Expression = dateTime-analysis-withFormat (/process_data/@datestring,"yyyy/MM/dd hh', 'FR', 'US', 'WIN',"CDT")
  
  Result = 18 August 2010 22:41:23 this
  
  So I try to put this value into a date field and I get the error:
  : Invalid ISO8601 DateTime:August 18, 2010 21:41:23 GMT:java.text.ParseException: date of: "August 18, 2010 22:41:23 this."

  
  I tried like 100 different variations to associate with an object date and time with the same result.  I can use the functions of analysis-dateTime or analysis-dateTime-withFormat throughout the day, but I can't get this string value in a proper date field.  Any ideas?  Please help as I'm about to pull out my hair... ... who won't be pretty.

  (Note: I know that my time zone came through OK but I am not concerned about it right now)

  To resolve this problem, I use ExecuteScript activity with the code:

  import java.util.Date;
  import impossible;

  String dateString = patExecContext.getProcessDataStringValue ("/ process_data/@input");

  SimpleDateFormat formatter = new SimpleDateFormat ("yyyy-MM-DD hh: mm :"); ")
  Date date = (Date) formatter.parse (dateString);

  patExecContext.setProcessDataValue ("/ process_data/result", date);

  where

  entry - process line with the dates of the string variable '2010-01-01 23:59:59 '.

  Date - date process variable
