• How to transfer data from the data in table 2D only once file?

  Attached file will write same data in table 4 times 2D file. Output must be in a table 2D.

  Someone will provide a solution or a reason to explain why the data are been ouputted 3 more times? Thank you

  I already told you a better and more effective method. The function of reading worksheet is on the exact same range as your text file and does everything for you. If you insist for some reason strange kernel to reinvent the wheel and write your own code, take the correct path. The use of 4 separate spreadsheet String to Array is the cause of your problem and I already said too much. Don't you think that get you 4 times the data is in correlation with the fact you are using 4 times the functions necessary at all? It is simply not true. Look at the diagram-writing block on a spreadsheet file.

  Here is a vi that might give you a few ideas to try:

• error when pass array 1 d by data in table pointer via Labview-built c++ dll

  I'm trying to generate a Labview VI to a DLL and let it be invoked by vc ++, by which a 1 d array is passed. However, I can't generate the DLL when you use the data pointer to the table, which gives the error like below:

  [ERROR]
  Code :-2147221480
  Strengthening of the DLL.
  Error when compiling the DLL as a function name or a parameter is illegal. Check function and parameter names are legal C identifiers and are not inconsistent with the LabVIEW headers.
  Additional information: 9 project link errors
  Type Library generate error. MIDL.exe failed during the compilation of the odl file used to create the type library.
  Note: The error indicates that the odl file has unknown types. This error is possible when
  works with non-standard types is exported using the method qualifier exporting files in
  release the configuration that have not been recompiled during the build process.

  The Prototype of VI define is as below

  

  But, if I use the pointer to manage through the table, the generation is successful, error-free. I write something to call the DLL built labview, which basically reads 1000 double the data of an instrument.

  #include "TestDQMaxDLL.h"
  #include 
  
  using namespace std;
  
  int main(int argc, char** argv) {
      cout << "Start testing DQMax DLL" << endl;
  
      int leng{ 1000 };
      DoubleArray rawDPData = AllocateDoubleArray(leng);
      test_dqmax_dll(&rawDPData);
      cout << "Successfully invoked the DLL!" << endl;
      cout << "DoubleArray.len: " << (*rawDPData)->dimSize << endl;
      for (int i = 0; i < leng; i++)
      {
          cout << (*(rawDPData + i))->elt[0] << "\t";
          if (0 == i % 10)
          cout << endl;
      }
  
      system("pause");
  
      DeAllocateDoubleArray(&rawDPData);
  }
  

  But the printed results are not correct.

  My questions are:

  1. why cannot generate DLLS with the data of table pointer. In this case, the argument of the function is as simple as a double array.

  2. for table handle pointer, when the resutls are incorrect and how to get the good ones.

  Any comments would be appreciated.

  BTW: I use Labview 2012 with Visual c ++ 2013 on Windows7 64 bit.

  I never needed to pass a table of LabVIEW handle external code. Search this forum for posts of RolfK, it is most likely to have posted such an example. I recommend that you keep things simple and remodelling your table a table 1 d 2D before moving on to external code and manage as a 1 d table (it's just a little extra math).

  Sorry I don't have a solution on why you can't build with a 1 d as a pointer of table table. If you post your project I'm happy to try to build (I'm on LabVIEW 2012, however), but as you said, it will rely on another machine, it seems more likely to be a problem with something on the specific computer where there is a problem.

• Get the data in table of javafx

  Bat I can get the data in table as:

  [code]

  for (int i = 0; i < dtm.getRowCount (); i ++)

  {

  for (int j = 0; j < dtm.getColumnCount (); j ++)

  dtm.getValueAt (i, j);

  [/ code]

  But how can I do this with javafx table? I google and google and google and no luck.

  In JavaFX make data are stored on a basis per line. Each line contains an element of type T (where you have a TableView), and each column specifies a value using a callback function that determines the value of the column of the value of a particular line.

  You can browse the data simply by practice

  for (T item : table.getItems()) {
    // ...
  }
  

  And then get the value of each column for each element of the given line, since you "know" what each column represents.

  For example, in the example of JavaFX documentation, you could do:

  for (Person person : table.getItems()) {
    String firstName = person.getFirstName(); // value in firstName column
    String lastName = person.getLastName(); // value in lastName column
    String email = person.getEmail(); // value in email column
  }
  

  If you want something really generic, you can try

  for (T item : table.getItems()) {
    for (TableColumn col : table.getColumns()) {
      Callback, ObservableValue> cellValueFactory = col.getCellValueFactory();
      CellDataFeatures cdf = new CellDataFeatures(table, col, item);
      Object cellValue = cellValueFactory.call(cdf).get();
      // do something with cellValue...
    }
  }
  

  If you have little chance to this need, unless you write some kind of framework. (I just typed it here, you may have get dirty you with guys a little to make things).

• Edit/view (data or Table column) value - cannot change the data, but it can be updated

  Hello
  
  According to the help of Oracle SQL Developer Center, the dialog ' Change/see value (data or Table column)' should "change the value of data" if we "are allowed to change the data." We strive to use this dialog box to modify/update data without having to write an Update statement, but is not to leave us. Us are not allowed to update the data, we can update via update statements. Even as the owner of the schema.table, it don't will change us the value in the dialog box "Edit/see value (data or Table column).
  
  Any ideas?
  
  We are on SQL Developer Version 3.0.0.4 build HAND - 04.34 and Oracle 11 GR 1 material (11.1.0.7) database.

• Extracting data from table without refreshment and without using the tab key.

  Hi friends,
  
  I have a problem I want to extract data from table without discount in the text field without using the Tab key. When I enter a field value any value then the text corressponding should enter into corressponding textfield without using the Tab key.
  
  for example. When I get back emp_id 101 in a text field then first_name and last_name, address would come in to the text fields corressponding without refresh and use the Tab key.
  
  How can I do that.
  
  Thank you
  Maury

  Hi Maury,

  I guess it's similar to: retrieving data without refreshing rather than Re: value of a textfield should enter into an another textfield without using the TAB ?

  If so, the only change you want to bring on the first is to use the parameter "Onkeyup" instead of "onchange" in the 'HTML Form attributes of the element' element.

  Note, however, that the user must move away from the issue at some point (for example, to click on a button), so the onchange will fire anyway.

• Data in table, overwritten by the null value

  I work on writing a VI that simulttaneously reading speed and pressure, then record them on separate tables.  Hit a wall at about 90% of the way through.

  The data (represented by random numbers for testing sake) comes in this central loop case then a VI "add to the table."  Here is where it gets Sticky: when I use a null at the beginning of this table (top of the page highlighted) my data continually gets crushed in the row of the '0' table of each loop.  But when I leave aside the value zero (low highlighted) my data are added to the table very well, but when I stop the VI together and restart, the new data values are just added at the bottom of the table.  Any help would be appreciated.

  Forgive my drawings Caveman to a VI, learning of the system on mine and just happened to a point of optimization.  Thank you!

  -Blaster

  

  Hello Blaster,

  What you did (perhaps accidentally) is created a uninitialized shift register, which will retain its value until the VI leaves memory. This can be an extremely powerful tool and can be used to create things like Motors of the Action, but if you need to erase the data between tracks, you will need to do additional work.

  Looks like what you want to do is to maintain the value of your table, while the application is running, but clear is when restarting the application - which is correct?

  If this is the case, then you have a few options.  My recommendation would be to leave the uninitialized loop and use the primitive 'first call?"to check whether or not it is the first time your processing loop reiterated and replace the table 'used' with an empty array and null.

  You might also consider using initialized worldwide feedback nodes, or half a dozen other methods that have benefits and different disadvantages.  Congratulations on the job through the application, by the way!

• data from table XY xy chart

  Hello, gentlemen.

  I have some data in 2 columns in a table, and I would like to draw the first column as the x axis, and the second column as the y-axis.  The way I found to do it is that separates the two columns and using him 'XY graph building' express vi, as indicated below.  However, I find it unpleasant and ugly.  Is there a better way to do it?  Ideally, I like to keep the data together, without separation, and I don't want to use a large vi 'express '.

  Thanks in advance.

  Try this:

  

  Simply decide on the two columns and group them. Make sure the index of wire to the lower of the two to get the columns instead of lines.

  Also note that the Index is resizable, so you don't need to a single instance.

  (If you want two rows, you need not plug all the clues on board index).

• write data in table 2D

  Hello, I am writing my data flowing in table 2D. I have attached a sample vi. What is the problem is that:

  As the block diagram shows, there is a 2D array whose first column has given fixed. Here's the 1,0.977,0.955..etc. These are my constant values X. The problem is on the writing of values Y in the second column.

  First of all, I run the program, it runs and I stop, so we calculate an average value because of the "magnitude and level Measurements.vi. So I want to write this value average to 2. line in 2.column. Then I push the pause button twice and the program continues again and stops. So I want the program to write average data of this stage in line 3. 2 column and so on. I want also to the value of 1 line. 2. constant zero column. However, after each loop is executed, the average value is always crushed by 1. row of 2. column. The other rows of 2. column are always zero. So, I want to like this;

  1             0

  value of the first run of average 0,977

  the value of the second run average 0,955

  average value of the third execution of 0,917

  0.88.. .and so on.

  0.842                          .

  0.767                          .

  0.692                          .

  0.617                          .

  0.504                          .

  0.391                          .

  0.278                          .

  0.165                          .

  0                                .

  After obtaining table 2D it liked, I will trace the XY graph and then curve fitting. My original vi cannot be fully open so I have attached a sample vi. Could you please help me as soon as possible?
