• Initialization of an array to match another size of array using the formula node.

  I want to get a few different pictures of the same length and constants in the formula node and output a table corresponding to their length after some minor calculations. Another post, I discovered that I can simply initialize the table as such:

  float pp [100];

  The problem is that I find myself with a much bigger picture than what I need. I want to do is something like:

  float [n] pp.;

  where n represents the entry of an array size in the form node or is something like:

  n = sizeOfDim(td0,0);    Here I use a table 1 d

  None of these methods seem to work. How do I initialize my picture 'pp' such that it matches the length of array 1 d of "td0?

  The more likely your initialization externally.  Create an entry named pp and wire td0 inside as well.  Now create an output with the pp even name and it will contain an array of the desired length.  Of course, this assumes that you want to edit all items in pp.  Otherwise, just use initialize the array to create a new table and feed in the length of td0, and whatever default value you want (ie. 0 or NaN).  The blank values will keep this value after the node of the formula.

• calculation using the formula node needs two clicks

  Hello

  I want to use this piece of code for a larger program. My goal is to take 10 values and calculate two values using a formula. I used the formula node as the calculation functions digital ordinary would be too heavy. If I click on save, it saves two values to a file.

  The problem that I am facing is that when I start the program, it works very well for the first time. The second time however, if I change the values, and then click on save, it still displays the previous values, or some altered values. I have to click on save twice to get the correct values. I don't understand the reason why this happens. Can anyone help?

  File attachment: Capture screen and VI.

  P.S. If the solution can help with the problem, I'm ready to change any part, but please, not irrelevant to suggestions on how to * improve my code *, because I've worked hard to make it work with another major project.

  I don't completely understand the description of your problem.  But I see two problems.

  1. the "Save" button actually belongs to the event that handles the record button.  And the case of the event should really be Jean-Claude Value Change of mouse down?

  2. your STOP at the bad mechanical action.  Since it happened so this just released, it is only true while you're pressing it.  It stops the upper loop, but can't stop low loop because your loop will also be waiting to save button to press.  Stop will always be false because you cannot press two buttons at the same time.

  Try to make your action to stop button to be changed when released.  You must return the button to false programmatically born of two loops.  In fact, it would be better to have a case of events for the stop button to stop the lower loop.

  I don't understand what you're trying to do in the upper loop.  You read a file as soon as possible, and it seems to be the same file that you create in the lower loop.  Why?

• Hi, I can't download photos from the camera, error 1201, any idea what is - this?

  Hi, I can't download photos from the camera, error 1201, any idea what is - this?

  A common problem on a MAC, less frequent on Windows based on my reading of the reports here in this forum

  You don't have WRITE permission in the folder where Lightroom is trying to copy the photos to (this file is put in the import dialog box in the Destination panel), so change your permissions.

  For future reference, the 201 is not the error code and no use for us here, it's the number of photos that are affected by this error. In the future, just give the complete error message.

• using the formula node array index

  Hello

  I'm new to labview...

  I am creating a vi that takes a number n and out the primes from 0 to n (i.e. including 1).

  My approach to do, he uses a formula node, but I can't understand how the table index or for each number first output.

  It seems that my indexing algorithm works very well, but I'm just pushing it into the array as an element.

  It'll will be great if someone could take a look at my vi and give me a hint on how to index properly.

  Thank you

  AA

  your output should be a table and index first use [index]

  also you have to declare the index and Prime]

  

• whites in the data in the table using the formula node

  I have 2 tables 1 d of data go into a loop. Inside the loop, there is a formula node that combines the 2 sets numbers and did a little math for them. If the result of the calculation is 0, it means that the value is not valid. Nothing other than 0 is good value. The result of the calculation comes out the knot of the formula and leaves the loop becomes a table 1 d. Then my table is saved in a spreadsheet. 0 really screw up my graphics, and I want them to just be white instead. I tried to use NaN instead of 0, but who also live up to my graphics. How can I place white on the output instead of 0 array?

  It seems that your real problem is to define what will make Excel leave gaps.  For LV NaNs graphics to do what you want.

  You can also consider getting the output array an array of strings. There may be string values (NO?) that cause Excel jump.

• applying the delay in the formula node in labview

  Hi all

  If you have not yet done so, please go through the tutorials free online on LabVIEW.

  Rarely is the node form the best way to write code in LV native LV constructions can be a little awkward at first for someone with programming experience text.  Once you learn how to use the stream and recognize functions by their icons, you can see that the graphical programming can be powerful and easy to read.

  For delays using the function Wait (ms) in the palette of Timing.  If you need a delay in the middle of a calculation (which seems unlikely), you may need to separate the calculation into two parts and put forward (ms) between the parties.  See the image below for a way to do this without no nodes formulas.

• Outputs not used in the formula node

  Hello

  To clean up my code and avoid repeated calculations, I want to use intermediate variables in my code formula node. To create those variables, the only way I know is to create an output variable of the node, which of course eventually unused. Y at - it no problem/inneficiency created by doing this?

  Thank you

  Define a variable inside the node form. Use the syntax of C

• Sorting table 2D using the formula node

  Hello

  • What l am trying to do is kind of numbers in groups.
  • A group consists of the numbers that are equal, or step upwards or downwards by a single value. Each group must be assigned to a column. E.g. O column of the table of entry test would consist of 5, 4 and 3, but not the 9 and 10. These values belong to column 1. However if the adjacent cell in the column was not empty then 9 and 10 would stay in column 0
  1. To better understand the programming formula node went to 1 d. I found that each cell is not treated individually with my code.
  • The final table of the orange entry test is that the data type l want to sort a 2D picture that ends up the same size chart.
  • In the code l provided my goal to compare each cell of each column line to determine if a cell is equal for example a = b, a + 1 = b or a-1 = b If Yes, then these values are in the right column. If this is not the case, a sort must be made to put a value in the right column it is.

  This is my first shot with node formula and l must admit others examples l found a bit confusing how a result has been obtained. I prefer to do any programming in labview instead of going to another program for results l am after. I tried to picture of programming just for this problem and found to grow big and very complicated then stopped l. For me the road to node formula should be simpler and more compact. My last resort is to use Excel but l still hope to do all the programming in Labview l you end up with a more dynamic program.

  Hello

  You are brilliant... bloody!

  I just couldn't she would repeatedly using tables, l have been on it for weeks. I never thought about how you solved this problem.

  I hate excel and text. I am graphically spirit therefore l such as labview.

  I had a solution in Excel yesterday, but your solution is much better than what l came with

  I'm very grateful

  Thank you

• When you visit a particular site my user name is entered automatically when you click in the required area. I want to avoid this, how?

  This site requires a username to be filled in a specific area and in another box, you enter a series of numbers generated by a generator of numbers (so not a password - different series each time that you open a session).
  However I do not want my user name appears automatically in the first box. Trying to change that in the security settings (extra-options-security), there is a password section where you can choose any exceptions to the rule of the memory (if the box remember is marked). When clicking the exceptions button, the url of the site I'm talking about is not displayed, and it cannot be entered either, since you can't delete here.
  When you click on the option "saved passwords", nor the site, nor the username is listed. I think I've read all the help sections regarding usernames and passwords, but found no solution.
  How can I avoid this username (so only a user name - not the usename/password combination), appear in the box?

  Click on the box, hover over the drop-down menu with your mouse, if you select the word you want to delete, and then press the delete key. If Firefox fills automatically in forms of control

  A gift card is not electronic media, so probably not eligible for usage of your iTunes Store credit.  credit balance iTunes Store can be used for all types of electronic media, including songs, apps, ebooks, audio books, movies (or rental), TV shows, etc.  Another example: charitable donations.  The iTunes Store has recently provided a way to make a donation to support the restoration of the disastrous flood of Louisiana.  But you can't use your iTunes Store credit. payment came from your designated payment method Apple ID.

• SCAN of the listeners and the earpiece by default everything is happening at the 2nd node

  I installed GRID/Oracle yesterday and I saw on the first node, there are scan-auditeur1, 2, and on the second node, there are scan-listner3.
  
  This morning, I try to create db by dbca and it gives me a warning that there is no default listener on the local node.
  
  Then, I checked, it not there no any listener on the local node:
  ps - ef | grep tns
  grid 31295 30685 0 13:47 pts/1 00:00:00 grep tns
  
  but on the second node:

  Check if the resources or cluster is online on node1.

  Use of the */bin/crsctl check crs * command to check the State of availability Services high Oracle and Oracle Clusterware stack on the local server.

  Use */bin/crsctl check cluster - all * command on any node in the cluster to verify the condition of the battery of Oracle Clusterware. The OHAS must run to run this command.

  Use of the */bin/crsctl start res - you * command to check the status of all resources.

  If the cluster is offline on node1, you can start */bin/crsctl start crs *.
