• Write to the file in Question Spreasheet

  Hi guys. In fact, I have a few questions about the most effective way to do a number of things. This VI aims to collect a tension all the seconds so as determined by the user and then draw the voltage vs the time it was taken. I also want to save all these in a text file.

  Currently, it works pretty well, but I don't know if graphs of my functions as I have (drop voltage and time values in a table and using Graph xy generation with the berries as inputs) are the best way to do it. Because I take only data each max ~ 5 seconds table size will never become a problem? I could run the program for a period of ~ 24 hours is 17280 values in the table at the end of the day.

  I am also having a problem with the way in which the values are stored in the spreadsheet file. How I put it in place now values are added to the current file that is not a problem. However they are not separated by anything when I open the txt file, whether they are in the same column. I know I put something inbetween them such as a tab or comma for excellent to put them in different columns. What is the best way to do with the numbers? Above all, I converted the concatenated strings then a tab/comma at the end of the data point, then get it converted to a number, but it seems that there must be an easier way to do it.

  Other comments randomly on the rationalization etc. my code is appreciated

  Thank you!

  The approach of the producer consumer, I'm guessing that I would simply put the DAQ assistant in its own sequence that takes a point of data every x seconds while the representation graph/writing/etc is it's own loop. Looks like a much more viable approach.

  I wasn't suggesting to the DAQ assistant in its own sequence. Architecture of producer-consumer, the consumer is usually (but not always) a state machine. The state machine gives you much more flexibility than a rigid sequence structure.

  Thanks for the comments smercurio!

  One last thing I wasn't very clear on the problem of delimitter. In fact, I want to insert a delimiter inbetween two tables, not just after them. So, right now, they are put into a single set. Time of tension then below it. I want a delimiter between the voltage and time so that when the file opens tension appears in a column and time appears in the next. While the file drop down a row and repeat the tension. Time. So I think I still need a way to add something to the tension or maybe insert an ascii value between them that will work as a delimmiter?

  Your problem is performing connections to the entry of table 1 d to write it in the spreadsheet file. I had spotted this when you first look at your VI. Table to build that creates the array for writing to a file in spreadsheet should have the opportunity to 'Concatenate entries"not controlled, and you should feed data to the entry in table 2D writing worksheet function.

• Image bitmap binary questions

  Good afternoon

  I am trying to convert an image into a Portable Bitmap format in order to to use with a web application that counts as 1 and 0 in the file. When I save the image in Photoshop as a Bitmap (.bmp) and Portable Bitmap (.pbm) and open the file in Notepad to see if it is really binary code, I met:

  "YYYYYYYYYYYYYYYYYYYYYYYYO YYYYYYYYO] YYYYYYYYYYY YYYYYYYYYYYYYYYU ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿo? ÿÿÿÿÿÿÿÿo ÿÿÿÿÿÿÿÿÿÿÿ ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿþ YYYYYYYYYYYYYYYYYYYYYYYYU] YYYYYYYYO YYYYYYYYYYU YYYYYYYYYYYYYYYU ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿu ÿÿÿÿÿÿÿÿo? ÿÿÿÿÿÿÿÿÿÿþ ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿþ wwwwwwwwwwwwwwwwwwwwwwwwt wwwwwwwwwp 7wwwwwwwwwwv 7wwwwwwwwwwwwwwwv"

  I don't know if I'm doing something wrong or if there is some kind of encryption. Please help me find the ones and zeros.

• write the bmp incompatible aid

  In labview 2011, the help on the bmp 'writing' vi reference is different from what is shown in the dialog using the schema context of the block for the necessary data types.  The reference to assistance to the first (2) elements of the cluster as U16 and U8, image type and image depth, respectively.  However, context-sensitive help shows these two as I32 (I just plugged a wire cut at the entrance of 'image' on writing in the comics and on bmp icon context-sensitive help, which displays the data expected for this entry).

  Which is correct?

  The function is correct, the file of detailed help associated with this function does not.

  Interestingly, the BMP reading help file shows the correct data types.

  Good fishing!  A person of OR will probably issue a CAR # to have corrected documentation.

• Write to the file in Question

  I do modeling experimental with a VI that many members of this Council greatly helped me go.  Part of this modelling is the creation of a periodic function.  I accomplished this by using 30 value entries 'Y' and a frequency to create sort of a 'function of unit', or basically, a period with a value of function, with a maximum amplitude of 1, while it is conveniently set on the scale.

  What I find is that it'd save these 'functions of the device' as well as their corresponding amplitude and frequency of file, that I cannot laod later in the program.  So, I need to write data to a file, (30 pairs of doubles, with 2 independent double rooms) and then have the opportunity to browse through all my saved both functions load the desired one.

  I used the express vi 'Write in a file as' before, but that seems to be a clumsy way to do it.  I then played with the various «write to...» "vi is available.

  For a relatively small set like that, is it interesting to a file rather than another type?  Of course, much data could go directly into an excel file, even if it should be reformatted to strings to store in the text.  I have little or no experience with bianary files.

  All file types are easier to load then go?

  And is it possible to have the (previously saved) functions available and selectable ring of menu, or will it prompt the user?

  That said, I'm looking for some general advice on the region.  I've read all the help files associated with and read some threads on the specific issue.  But being new, I'd like to hear how you professionals would approach this function.

  My current code is attached.

  
  

• Binary question and app.activeScript

  Hi all

  I'm trying to get a script running. The syntax looks like:

  #targetengine "foo."

  var scpt="@JSXBIN @[email protected]@MyBbyBnAge... « ;

  app.doScript (scpt);

  I get an error and it seems to be related to the use of the app.activeScript.parent in binary alphabet.

  In the binary file

  Scripts folder
  var scriptFolder = Folder (app.activeScript.parent);

  Is this something known or do me something wrong?

  Is there a workaround, it would be better to make radically different?

  DRM for any input

  Best,

  Loïc

  Try something like this:

  #targetengine "foo."

  Folder.Current = app.activeScript.parent;

• BMP bmp binary & write on MacOSX

  Hello world

  I have two questions for you!

  First of all, I need to convert a bmp to binary file.

  What I'm supposed to do is: open the thread bmp with a file, unflatten dialog, to use it for other animals (convertir convert in grayscale, using a median filter, etc.), and after changing the it, I would like to save it. So I used the flatten pixmap vi and vi of the bmp file writing. But here's my problem: he always write the new txt file, and not bmp! :/

  Second question: I would like to convert the same bmp in binary file. I know how to get from binary to bmp, but not vice versa.

  Any help ?

  Thanks for all!

  Valentine

  (If you need more information, just tell me!)

  Convert just a file that is located in a specific location means that you can follow the code below

  

  But I'm not sure the MacOSX.

• Strange binary file write behavior

  Something a little strange when I try to write data to a binary file. I have reproduced the issue in the StrangeBinaryFileBehaviour.vi which is attached below.

  I simply write two bytes in a binary file and yet my hex editor/Viewer tells me I have 6 bytes of data, a screenie of the discharge of the binary hexadecimal editor is also attached

  Maybe that I lose the plot and I'm missing something, forgive it is late on a Friday

  Stroke

  Wire a FAKE to the Terminal "prepend array or string size...? The default value is TRUE, so that you get extra bytes, depending on what it is to wire.

  For a 1 d array, you would get 4 extra bytes to the size of the array (I32) and tha of what you see.

• IMAQ write bmp conversion problem

  I automatically tries to get a 3-d chart to write the content of the image in a bitmap image, I am currntly using the property node "get image", and then the bmp.vi 'write' but gives a bitmap of poor quality as well. I found simply right-clicking on the front panel and with the help of "copy data" and then paste it into ms paint gives really good quality. (see attachment) So:

  There are two ways to write a bmp file, as I discovered: [n/b, I am running 8.2 lv]

  writing bmp.vi & imaq write bmp.vi

  the bmp.vi of writing requires an input of a cluster with the image data it contains in the form of a 1 d table, the bmp of writing imaq simply to an input image.

  Q: is there a good way to convert between them as the bmp.vi of writing returns less Muslim bitmaps imaq writing bmp.vi is capable of.

  Or is it a way to dirrectly read an image other than 'get image' use 3d as a method node? or data 'copy' lets get data wrote?

  Chears John P.

  Hi John,.

  If you set number of bits of the image get invoke node to be 24, that this feature will also define the bitmap that you write to drop to 24 bits.  Simply connect to a constant of 24 to terminal nodes invoke bit depth.

• Why do I ask a question in order to create an account here?

  I wanted to respond to an existing question, but I couldn't do it without another question.

• Opening writing BMP.vi DLL

  I'm trying to convert IMAQ images BMP images without the need to use the BMP.vi to write, because the process of writing BMP files in a directory then reading/loading them becomes slow with huge data files. I opened write it BMP.vi and found a DLL inside that I'm assuming that performs this conversion. I don't seem to be able to open it in Visual Studio? Any particular reason for which his hidden?

  Hello Nik@Bris

  LabVIEW is unfortunately not a package of software open source. Therefore, it is not possible for the clients to access the dll written by National Instruments LabVIEW.

• Can a weird question we use Data Guard to apply the bidirectional log?

  Hi I have a question about Data Guard, can we use Data Guard to apply the bidirectional log? I mean keeping the two of them primary and standby to Active status (read write Mode).
  
  Maybe my question seems silly, but I just wanted to check on it.
  
  Thank you

  Laughing out loud

  That Golden Gate or water courses that will work in two ways. One or the other. Puts additional requirements on the hardware is the downside.

  Data Guard does not do that.

• Number of question pools

  Is this acceptable as if randomly in a quiz question slides are actually the same number as (rather less) the total of questions in pools? The random display of questions will always take place? My first analysis, it seems to work OK, but I just wanted to check a second time with the experts...
  
  For example, let's say that my quiz has two pools:
  (Dogs_pool and Cats_pool) of 10 questions each
  .. .and the quiz contains 20 random question slides completely - 10 that point to the Dogs_pool and 10 others that point to the Cats_pool.
  
  I recognize that one of the benefits of the use of the pools in question are real questions are drawn from a larger pool. However, another advantage is that the questions are random. It is this second advantage that I hope to accomplish in our quiz, because we do not have the time to write a lot of additional questions for pools.
  
  Thank you!

  Hi Jan

  If you decide to shoot at random, that's what you get regardless of the questions in the pool. Here's how it works.

  Let's say you have issues ten dogs in the pool. If you create ten random questions that each point of the pool, you will use the questions in the pool. When the randomization, you run the risk of presenting the same question twice. Once a question in the pool has been used, it is no longer eligible to use. It also means that you should be careful with the addition of slides at random. It is possible to have ten questions in the pool and insert an eleventh question randomly pointing to the pool. You will be notified, but not immediately. This does not happen until you start to publish.

  Hope this helps... Rick

• Constant string BD is safe to use a password internal unchangable?

  Hi all

  reasons to restrict access to some of my program ini files, I intend to use the password of the ZIP files coming with the tools of librarians openG and so save these critical files in a ZIP protected archive. Of course, some time when running the initialization of the program I have to give uncompress works the password required to read the contents of these files. Now my question is whether the use of a constant of simple string on the block diagram would be safe enough to use here.

  I tried to find a constant text string in the saved VI file using Notepad ++ test but could not. So far so good. Is there a simple way to get any of the VI file constant string value without using LabVIEW and the opening of the comic (which would of course be PW protected so)? The necessary level of security is really not high, I want to just exclude any obvious loophole that I might not be aware of here.

  Of course - then that ZIP archive remains open for read access at initialization, anyone can read the files from the hard drive. But it would take a number of "criminal intent" I really don't want to guarantee against the application.

  Thanks for the thoughts that anyone could share.

  It depends on your needs.  Looks like you don't need to be impossible to crack you want just a security level.  For this the zip method is probably fine, but keep in mind that the decompress function is as you said, a loophole in there self because the files will be unzipped at any given time.

  Another solution is to write your files in binary form.  If you know the structure of your data you will be able to understand it.  It gets a little pain that you need to update your data type but a def type helps out with that.

  EDIT: to also answer your question, I never could find anything like a string on a block diagram, my analysis constant a VI on the disk.

• Include .vi with DAQmx .vi SERIES

  Hey everybody,

  I searched the forums looking for examples of the integration of two .vi, but are short on key words to search for. So here's my question.

  I have two separate .vi that operate independently. The first collects the DAQmx data and writes the data a binary file. The second collects data from the serial port using VISA read and writes the data to a .csv file.

  My main .vi designates the DAQmx read because it has the GUI on the front panel. I would take and display 5 string since the VISA .vi variables and post it on the DAQmx .vi. But I can't do it!

  I tried to create two parallel loops in the DAQmx .vi but when I do that, the VISA file does not work.

  Any help will be great, because I think that this problem to be more simple I have do it. Thanks in advance!

  -Yao

  Post your VI.  If a loop is not running up to a another loop ends, then you do not need parallel loops.  You must have a data dependence caused by a wire connecting to one another.
