• How to save the data in a form called?

  Hi all.

  I have two froms.like FORM A and FORM b.

  I have a button on the FORM B.

  When I click on this button, FORM B and FORM data should be store in the database...

  I wrote something like this in the form B

  when_button_pressed->

  commit_form;

  go_form ("c\user\babu\FORM A.fmx");

  commit;

  Here, my problem is when I click on save button only saved FORM B, FORM A not memorizing the data in the database.

  Please help me and tell me where the error...

  Post edited by: N.B.Babu

  I guess that the modules form a calls B with OPEN_FORM module (..., SESSION), IE. Module B works in the new session of database

  (by the way, the database connection is the same, because the connection to a database can go several database sessions).

  Your code cannot save the data in the two sessions of database:

  commit_form; -This saves the data only from module B (because A module work in diferent database session).

  go_form ("c\user\babu\FORM A.fmx");  -Now you in module A.

  commit; -This has no effect, you are now on the module to a.

• United Nations-editing data from a file, without eval

  I play with the writing of data in a file so that it can persist between sessions. I use

  f.Write (Data.toSource ());

  to save my data, where f is the subject of my file, and

  data var = eval (f.read ());

  to retrieve the data from the file. But that seems to be a way very unsafe to do things. Of course, it is unlikely that someone will use, preference files AEscript as a door furtively, but it's always just security by obscurity.

  Is there a way to read data serialized into a file without using eval()? Or I have to roll-my-own parser / serialize to do safely?

  It turns out that this question has an answer here:

• How to save profiling data?

  I would like to save profiling data. The documentation states:
  
  1. Select the application in the profile view.
  2. open the drop-down list in the profile view, and select Save.
  
  My problem is that I can't seem to locate this combo... I've probably got to be overlooking something... someone wants to give me some additional information?
  
  EDIT: it's for the latest beta version of Flex Builder 3

  Hi wouter vdb.
  You can access the drop-down list on the toolbar of the Profiler, there is a little white down the arrow to the right of the Finish button.
  When you click on this button, a menu opens and the registration option is available.
  I hope this helps.

• How to save the data of different rates in a single VI?

  Hello

  I tried to acquire 2-channel measurement of voltage at 10 kHz and analyze data, finally to save the data to both 1 kHz and 1 Hz. What I did is this loop of producer/consumer use to do the work of recording at different rates. I have queued all the data in the main loop, and then removed the data and write it to the file in other loops. I added "wait = 1 ms' a consumer loop for recording data at 1 kHz (loop of fast logging) and added" wait = 1000ms' in another loop to get the slow 1 Hz (logging loop) data record.

  My problem is that the data record works fine in the case of 1 Hz, but it does not work for the case of 1 kHz. Although the time-out period defined as 1ms, the interval between two samples in the loop of fast data recording is about 100ms.  Subsequently, 1ms, 10ms, 100ms, 150ms tried in this loop to see what intervals are in these cases. I found that the intervals are same as assigned in the timeout greater than 100 ms, but if the time-out is set to 1ms or 10ms, the intervals are again around 100ms.

  My question is - why I can't reach data record 1 kHz using loop of consumers/producers, while the same way works for the case of 1 Hz?

  Thank you very much

  You are sampling at 10 kHz and you want to back up your data "as if you sampled at 1 kHz and 1 Hz", if I understand correctly.  I also understand that you use the design of producer/consumer model to help with this (a good idea).

  I'm assuming that the producer 'product' a segment of data at a time, to say the value of a second of data or a 2 x 10000 I16 (assuming a 16-bit integer A/D) table you put into a queue and wait for the consumer.

  If you have data at 10 kHz, how do you get representations to 1 kHz or 1 Hz?  There are (at least) two possibilities - average data over the interval of proper time, or (re) sample data.  The good thing is that you can handle the situation 1 kHz and 1 Hz, essentially at the same time and in the same processing loop.  I'll discuss the case 1 kHz - with the assumptions I made, the case of 1 Hz becomes almost trivial.  I'll discuss treatment also just one channel, as it is similarly almost trivial to go from 1 to N-channel.

  If you have 1 second of data sampled at 10 kHz, and will "reduce" 1 second of data sampled at 1 kHz.  Note that you have 10 samples for each data point that you want in the end.  The "Averaging" method said "Replace all 10 points in the average of these 10 points", while "resampling" method said "replace 10 points with, say, the first point, ignoring the others.  An easy way to do this is to use the Reshape feature to transform an array of 10 x 1000 elements of your array of 10000 items 1-D 2D.  Now, you can use a loop FOR an average of 10 items or simply extract the first.  [This is where almost everyone, including me, a mistake - when you put a 10 x 1000 2D array in a loop, you get 10 iterations of 1000 items and we want 1000 iterations of 10 items.]  Oops, what to do?  [Simple - converts 2D array before sending in the loop FOR.]

  So when you have processed your 10,000 points and got both 1000 samples "1 kHz" and 1 "1 Hz" sample, you write each of them in their respective folder and wait for the next item in the queue of the consumer.  Consumer focus on the queue loop, it will automatically 'block', waiting for the producer of the 'feed' some data.  Note that the producer generates data once per second, producing 10000 points for the consumer in the process, but the time to deal with these points and perform the required disk i/o should take only a few milliseconds (certainly not more than 100, even if writing to a floppy!), so you don't have much time to do other interesting things (such as display data).

• save millions datas in a sec

  Hi guys, I tried searching, but I have not found the answer, that's why I'm writing this.

  How many points/samples which can be saved in 1 sec with Labview (max)? It depends on my PC specs? I searched this forum and found this old thread http://forums.ni.com/t5/LabVIEW/Extremely-large-files/m-p/730139. With this program of Altenbach (Herr), I tried to save the data to a .txt file using the Save1Data.vi and Signalsub.vi. The problem comes when I try to save as 100,000 points. Y at - it advice to save as many samples, I need that to save about 1 million samples in 1 sec?

• Save the data to the excel file

  Hello

  I make a program reads the value of the probe via serial port... but I don't know how I can record this data in excel file... I open the example in the labview example, but I don't want to like this... becaue I use a while loop in my program that cause opened "multi" excel file... . How can I solve this problem?

  You need to think about what you want to do, not how you want to do.  I'll make a few assumptions here - adopt to your notebook loads "real."

  I guess you want to take a series of readings from a device (sensor, serial port).  I suppose you take multiple readings, perhaps their display on a table or chart, for a certain period of time.  Once you have a set of data, you want to save all the data in an Excel file.

  If this scenario is correct, there are three distinct phases to this task - implemented the data collection (open the serial port, manage the interactions of the user according to the needs), data collection (and potentially produce tables or graphs) and save the data.  Note that only step 2, collect data, involves a repetitive action appropriate for a while loop.  Once you have all the data, you can then open an Excel report, use something like Excel table easy to put the Table in the report or chart Excel easy to put a chart in the report and save the report in evidence, save the report.

  If you are using a relatively recent version of LabVIEW (2010 or later), the new generation Excel report screws are pretty easy to use.

• Save triggered data of 2 modules

  I use SignalExpress (3.0) with USB cDAQ-9172, NI9203 current and voltage NI9201 module.  After the acquisition of (continuous) data, I use a trigger current 9203 signal software to analyze and record the triggered data (collected on the 8 channels on 9203).  However, I am not able to save the data of the voltage module 9201?  Looks like that the trigger for software only accepts a single module entry (I think).  As indicated in the attachment "triggering Input.jpg" I can only select 1 module as input for the relaxation of software (current module or module voltage)

  Is it possible to trigger on a single track and then save the data of these two modules?

  Thank you!

  Ryan

  Hey Ryan!

  You can actually do all this one-step DAQmx Acquire.  There is a tab in the acquisition stage where you can specify your trigger.  Then, there's a recording options tab up at the top where you can choose to save your data when starts it logging to a file TDMS that can be read in excel.

• Save the data on the button and then save the data on a spreadsheet on another key.

  Hello

  I am a new user of Labview. I'm developing a Labview 7.1 program that will record data on the keys. Another button, he must stop recording, and then open a file dialog box to save the data stored on a worksheet. I read in this forum that I have run several loops in parallel but unfortunately I can't see the examples because I use an older version of Labview. I tried to do to pass the data in a table, once recording is started, and then I carry the data to write a function that spreadsheet inside an another case statement. However, once I put the writing on the spreadsheet for the case statement he cannot write. I tried to put out the statement box but it save only a single set of data. Sorry if I am not clear with my explanation. It will be greatly appreciated if someone can give me some advice on this.

  Thanks in advance for your information.

  See you soon,.

  You want to build a table of data.
  If the Boolean value is true, you will add a data point in the table.

  If it's wrong, you do not add anything, and the loop will be re-iterate.

  In the example below, the same code appears twice.

  Half top shows the case of 'Real' and the bottom half shows the case of 'false '.

• Save the data in a horizentall

  Hello

  Any that offered little help on how to save the data in a portrait. As a result of my attachment all my datas saved az a tables!

  And also, I'll be glad if you told me that I can add text in front of my data as an outamaticlly to explain?

  Any suggestions would be greatly appreciated! Thank you very much!

  Sincerely,

  First convert your string numbers using decimal channel number.  Once your numbers have the appearance of a string, you can format the text with them.  If finally, you can use concatenate strings to concatenate (add all channels) your number in the string with another text format:

  

  This code would create the following string:

  

  Then, you can save your all channels on a line using the same method as above.
