• How can I generate a single random number on a button for use in a VI?

  I'm creating a new VI and need a new random number every time that I hit a button... it will eventually be replaced by externally triggered en boolean, but for now, I would like to just press a button, get a new number, use this number, click the button, get a new number (previous deletion), etc etc.

  Thank you

  Just to add to what SAM has shown you can generate in a different ranges without limit it... It's just a very simple logic... Try this...

• How can I create a random number generator, protected by password and username?

  I have attached a VI that is a random number generator. I want to just be prompted for the name of user and password when I start this generator. There should be three names of users and passwords found in three different files. I would like to know how to link the code username/password for the code generator and how do the program to know that there are three txt files in my computer with usernames and passowrds.

• How to generate a single pulse with DAQmx

  I need to generate a single pulse using DAQmx.  Many of the example of the AO screw blood generation using waveform (multi) .vi buffer generation.  This VI generates a + / amplitude.  I want that my pulse to go from zero to a positive amplitude.  How to achieve this?

  Thanks in advance.

  What amplitude and what pulse width?

  If you have found an example with regeneration, to get a unique waveform, you can disable the regeneration and just do a single entry.

• Generating unique random number with a Boolean signal on an RT target

  Hello, this is my first time asking your question. I apologize if I post this question in the wrong Council.

  [What I'm trying to do]

  I am stable heating and cooling in an experimental space that I (with cRio9024).

  And I'm putting a different experimental condition in space based on the function 'random number '.

  'Different experimental conditions' sense different combinations of Tind, Twat_s and mdot (refer to the attached VI).

  For example, if I get the Boolean TRUE signal.

  I should have a set of [Tind, Twat_s, mdot] = [21,14,0.05], and IS this set of numbers until this Boolean signal goes to FALSE.

  And when the signal passes to the TRUE once again.

  I should have a different set of [Tind, Twat_s, mdot] = [24,16,0.15] for example.

  [I]

  Problem I am with my code is that,

  When the VI is running, the random number remains the same as the Boolean signal is set to TRUE.

  From what I tried so far for the last couple days, using 'the event structure' was the message more concerned that I found,

  However, LabView help tells me that "structure of the event" on the objectives of the RT do not support the events associated with the user interface such as the façade of VI or controls panels.

  I would therefore ask a quick help, since my knowledge of LabView is exhausted at this point.

  

  This is so the part where I want to generate random numbers, WHEN this structure case is TRUE.

  convert whole numbers, random numbers

  Use them as a table index,

  while I can choose conditions from radom to the given set of conditions.

  Once more, I want to do is,

  generate a SINGLE random number series when the structure above is TRUE.

  Hope I have developed quite clear.

  I'm appreciated for any kind of advice.

  Thank you!

  You just need to store the Boolean from the previous run. Then the logic would be (I'll call her Boolean previous B_prevand current boolean B):

  If B AND B_prev > don't generate new values

  otherwise if B > generate new values

  Edit: to store your Boolean value, you can use a feedback node, or a loop with N = 1 and a registry change.

  In the code the first comment is wrong in fact, I think, this one:
  "There is no table built in oracle, you must declare your own."
  I remember there are some types of collection of the system, if I not mix with something, I remember there was a sort of like they were undocumented, so we can say legally that the comment in the code has always been right.

• Random number by computer

  Hello

  I have a comp with a random number is generated,.

  That's what I have on the keyframe of the rotation:

  seedRandom (index, true);

  myValue = random (50);

  time * myValue ;

  When I duplicate this model, all produce the same results.

  Is it possible for each model generate its own random number?

  Thank you

  Lol the essential point is that a single model makes only once, so it cannot present a different picture depending on where you use it.

• How is PDF link to MySQL database - it done?

  How can I link the data entered in a PDF form dynamic to reside in a MySQL database. I do not seem able to make a connection.

  Here are the steps that follow:

  Mandatory / new login / name: testdata; Description: database OLEDB / Connection String: build: SQL Native Client / Source of data: location of the database SQL (.mwb); Connect to the server: localhost

  But when I test the connection I get an initialization error and the connection times out.

  So my question is: How do you connect the PDF fields in a MySQL database? and what I am doing wrong? Is this a feasible process to bind also the boxes to check and other areas to a database? How you would bind the data dynamically - say if I choose a certain area in a menu drop down, certain other fields will fill through the database?

  Thanks again for all the help and insight.

  PS I have attached a sample form (not yet completely integrated to accept some data) and a database of MySQL example (no data on the inside).

  A number of things before you go this route.

  1. you will need to load the driver ODBC for MySQL on your machine and each machine that will want to use this form.

  2. next, you need a DSN that creates the link between the MySQL DB table and your form.

  3. If you use Acrobat to run the form, then you can proceed. If you are using the drive it does not support DB connections free player expand the document using LiveCycle Reader Extensions Server.

  Have you met all these criteria?

• How to generate a random number within a specified tolerance and control than tolerance.

  I am trying to simulate data without using a data acquisition device using a random number generator and I want to be able to control the "range" the random number generated well.  On the front panel, the user can enter a nominal number, and the random number generator would generate numbers more or less disponibles.003 this number nominal.  The data would be delayed on a chart.  Someone knows how to do this?  Or if it is still possible?

  Just for the sake of information, the random number is supposed to resemble thickness measures, that's why I want to simulate more and less disponibles.003 because the data might be thinner or thicker than the nominal value.

  Thanks in advance!

  Two ways of approaching the issue.  First of all, for even distribution, you can 'Roll the dice', which is the (0,1) random number function, multiply the result by 0.06 and then add Mean - 0.03 to center around average distribution.  If you simulate a real process, my initial guess would be that the results would follow a normal distribution.  In this case, you can use the VI of white noise Gaussian of the palette of generation of signals with a standard deviation of 0.015 if you wanted 0.03 to be the point of 2 sigma, then add average results.

  Divide the random number by a number specified in the front panel.

  If the number of seizures is zero, the VI program should light a LED in the face to indicate a divide by zero error.

• How can I generate multiple unique random numbers?

  Hello

  I am trying to generate multiple random numbers between a given set of numbers (1-52) and do not have the same number generated twice within this group. I can compare the numbers of last and next with the function to compare, but how would I go about comparison of all numbers generated without using a huge list of shift registers...

  Any help/ideas are welcome and appreciated.

  Jason

  Solved my problem. IM passing the random number through a registry to offset to each case and build a table every time. I then searches the table for the new random number. If the number is not found I get a value of-1, another thing is an index value of 0-everything. If a comparator greater than (-1) indicates that the same number is in the table and then I can raise this matter until the same number is not found.

  Kind regards
