Table of cleavage according to its index

Hi all

I want to have a 'demux' block which, having a table (2Nx1) as input, splits the data into two tables (Nx1) as output the first array index is even or odd...

At first, I tried to implement this with a structure matter in a while loop:

But this does not work because I can run ony this .vi when the outputs of the case have option "default if unwired" located on. And this will happen not a pair of paintings (Nx1), but a pair of paintings (2Nx1). The first table will be [value, 0, 0,..., value] and the second will be [0, value, 0, value...]

I want to get rid of these zeros...

Any tips?

Thanks in advance!

Try the table to decimate . That's probably all you need.

Here are some general comments to your code in general:

  • As the number of iterations is known before the loop starts, you need a loop FOR. no need to wire N or compare the number of iterations. It will automatically browse for all items in the table of entry autoindexing and then exit the loop. In addition, output indexing on a loop is much more effective, because the table output sizes can be determined and allocated exactly before the start of the loop. With a loop, labview can do that.
  • If you 2012 LabVIEW, you can use conditional indexation on the exit tunnels.
  • You can wire the rest directly to the structure of the case and make a case 1 and the other 0. Less code! (See my signature).
  • To check the odd vs even, a logical operator AND with 1 is sufficient and effective.
  • The '-1' is before the loop because you have to do only once (well, the compiler recognizes loop invariant code and will in fact create the code compiled as if the "-1" have been before the loop, but why not be explicit?)
  • When you create a screenshot of the code, try no. to select anything.  Black dotted outlines are bothersome.

  • How to customize display in ItemRenderer according to its index in the dataProvider in Flex 4.1?

    I went through a lot of forums to get this answer, without success. I have to admit, I'm quite 'green' with Flex and my mother tongue is the French, so if I am not clear, I apologize.

    I would like to use the same ItemRenderer for all items in a list, but only for the first (index = 0) item in the dataProvider I have 1 child of the non-visible ItemRenderer.

    Currently, I have something like that in the ItemRenderer:

    override public function the value of {} data(value:Object):void

    var itemList:List = owner as list;

    var listProvider:ArrayCollection = itemList.dataProvider as ArrayCollection collection;

    var isFirstItem:Boolean = false;

    If (listProvider.GetItemIndex (Data) == 0) {}

    isFirstItem = true;

    }

    }

    And then if isFirstItem = true, I hide the child I wanted to hide for the first item in the data provider.

    The problem is that listProvider.getItemIndex (data) == 0 seems to be true not only to article 1 in the dataProvider. The child I want to hide becomes too hidden on some (not all).

    It seems to be linked to the fact that the list has a scroller and so not all items in the list are shown at the same time.

    Does anyone have an idea how I could do this? Or just some advice, I'm really out of the solutions here.

    Thank you!

    do you explicitly say if the first element then hide the child, see the thing of the child

    itemrenderers are reused, so if you do not have the else clause so when you scroll the rendering engine is displayed in its original state

    1. What is the exact syntax to export and import a table with its index?

    You will need to use the "Table". An export of table mode is specified by the parameter TABLES. Mode table, only a specified set of tables, partitions, and their dependent objects are unloaded. See: https://docs.oracle.com/cloud/latest/db121/SUTIL/dp_export.htm#i1007514

    2 How can I import the indexes in one tablespace other than the table itself?

    You can only export the table first without the index by specifying the EXCLUSION clause in order to exclude from the index (see: https://docs.oracle.com/cloud/latest/db121/SUTIL/dp_export.htm#i1007829) and then manually create the index and specify the different tablespace when you create.

  • Is there a way took care in the reorg table sys.job$ (and its indexes)?  (Oracle 9)

    I have an old database that has a table of great sys.job$ and the large index on it. (indices are just standard installed indexes nothing we did)    However the table has very little data in it now, only 22 rows.   Yet between the table and index is > 1 GB in size.

    The enforcement team asked me to reorg or shrink the table sys.job$ and explained its large size is probably due to the fact that they believe some process went wrong turned for years resulting in job creation, but his long since been cleaned.

    What motivates is to save space in the SYSTEM tablespace and possibly help some query performance.

    I know that in general its forbidden to directly manipulate the sys objects (such as truncation, insert, etc. with the exception of sys.aud$).

    Y at - it a taken way supported to reduce the size of this table.  Any document referencing.

    Yes, there is a way taken in charge.

    It's called "Recreate the database"

  • sorting table, how to get the new index of the last value?

    Hi all!

    I use a Subvi, which adds a cluter of the parameters to an array and then sort this table by one of the parameters in clusters.

    It works very well, with examples, that I found in this forum

    but now, I would like to know if it is possible to obtain at the end of the new cluster index first added.

    See attached VI

    Thank you

    You take the size of the table and insert the new element to this level is anything other than the table of construction and a simple construction would do that.

    In your question, I assume you're asking on the index of the item that you inserted after the sorting of the table, right? In this case, you can compare the cluster element that you introduce to the initial with the cluster table you get after a sorting of the table. This will give you the index of the item that you insert at the start.

  • Remove unwanted in table 2D lines not knowing the index for which you want to remove

    Hello!

    I'm new on Labview and I hope someone can help me with my problem.

    First import an Excel worksheet into a 2D-string table. For each row in the table, then I want to compare the data in a specific column (which is a date (timestamp)) with the current date. Lines containing a date with number less than today's date, I want to put in a new table and the rest I have no need.

    I managed to create a time stamp for today so that it matches the timestamp of Excel. But for comparison and the creation of a new part of table, I have no idea how do. I tried several ways with no luck at all (probably because I don't understand all the screws that I use).

    Happy for all the help I can get!

    You are on the right track! (although your attempt lists only the datetime values)

    What you need to add/change, it is the resulting table needs to be connected to the loop as a Shift register (with an initial empty table), and in the case you use either Build table to add the current line or send the non modified through.

    You'll probably want to send all through and not only the datetime value.

    You will probably need some tweak to use only the date, but similar to this:

  • Change table cell color according to the input data

    Hi, I have a table in a form and I want the cells to have a dark in each cell if it has not entered data, but the cell background color to change white if no text is entered in the cell. Is it possible to do?  Thank you.

    You can use the fillColor for this property. It depends on your table structure how you do this. If you have relatively small table say 3 columns. 3 rows and then in each cell of sortient / calculate event you can put the following script.

    If (Cell1.rawValue == null & Cell2.rawValue == null & Cell3.rawValue == null)
    {
    Row1.fillColor = "255,0,0";
    }
    else {}
    Row1.fillColor = "255,255,255";
    }

    If you have a larger table, then you must create a function for it.
