• Is it possible particularly handy/quick to disable controls (multi-column listbox) when executing the output material associated?

  Please excuse me if the title of the post is not clear, I would try to explain what I need to do here.

  In the application, I am currently in train, UI use multi column listboxes in several places where a set value (one line) is selected, and based on the rowset / selected, relay/material are enabled to match a given configuration (which is then verified with your comments).  The problem is, I can easily rush into the user interface and make program stuttering and choke...

  I just put my finger down in one of the rows in the listbox control and drag my finger up and down the screen as a 5 year old child see a touch screen for the first time - he tries to each entry cache/buffer.  After I stop being 5 years old again I sit and listen to the click click of the relay for a bit.  One of these list boxes, I've already implemented enable and disable to pieces of code to implement the right before the digital output and solve the controls right after that feedback has been verified.  It was kind of a pain to do, so I wonder if there is an easier way to do it.

  Any idea or suggestion appreciated!

  Thank you

• Is there a way to get a list of tables with multi-column primary keys?

  I have a model over 1000 tables, each containing primary and some keys with unique indexes.  I need a list of multi-column primary keys and a list of the unique indexes that are not the primary key.  Is there a way this information easily?

  I have a generator that creates the merge instructions and I needed a way to retrieve the PK, if any, UK and otherwise the first Unique Index.  This comes from a cursor, so there are some variables for the schema and the name of the table and a constant for pk 'P' and 'U '.

• can update you a table with a column field with a default value

  I'm looking at a table (table_one) developer and basically, there a column field called is_update and the default value for this field is 1.
  
  I was wondering if it would be possible for me to use a syntax of the form update
  

  update table_one t
  set t.is_update = 0;
  where t.id = 221;

  because I tried to do and the update does not work

  Semicolon (;) is the problem!

• How to increment the index of row/column in multi-column listbox

  Hello

  I developed a program in which the multicolumn list box values are read and forwarded to another mechanism. To read specific values in the list box, I used index table to retrieve the value of a particular cell to the instrument.

  Allows, for example if I want to run the VI several times and I want to increment the line index whenever the tracks VI as well as for successive runs, the values of the next level of lines are read.

  For example. I have the following listbox

  HAD Vd Vg

  1 0.3 0.2

  2 0.4 0.6

  So for the first round, based on the index which I note the listbox can read 0.2 and 0.3 and assume that if I run this VI for lets say 2 times during the 2nd time it should read 0.4 and 0.6 instead of 0.2 and 0.3.Is it is it possible to increment the line/column index automatically? Please help me because this is the last step of my project.

  Thank you

  Robin

  Your VI runs millions of times per second and elements within nanoseconds. You need to prevent this.

  Here is a quick modification that goes to the next line, every time that you run the VI again and again when he's run out of items.

• Programmatically change the selected cell/line of control multi-column listbox

  I want to programmatically change the selected cell of a multicolumn list box whose selection Mode is set to highlight the whole line.  I would use this to highlight the line whatever the list box, I chose to.  It would work the same way if the user has clicked on a line to select and highlight that particular line.  Set Active cell does not fulfill this.

• node property outputs false values

  I'm having a problem with output occasionally erroneous values for a control.  I move the mouse cursor around the screen, between 4 controls programmatically.  Most of the time it works fine.  Every now and then, the cursor will move to the wrong part of the screen.  I followed him there down to the property node connected to the refnum command.  I plugged the refnum indicators enter the property node and values that come out as seen in the block diagram:

  

  The subvi is called for each movement of the cursor.  Exit normals for controls are listed here:

  

  However, sometimes the wrong width is released:

  

  Sometimes the wrong position at the top of the page (this is the first position of the previously selected control):

  

  Sometimes the wrong height:

  

  Sometimes the different controls and several times, he displays the same values of bad - for example the width sore 1944 went out several times during the collection of these data.

  I have a fairly complex system - a DAQ system (with a wheel) connected over the network to my computer and a fairly complex level vi.  There is a Subvi Panel that opens to define configuration settings, using the wheel, events user to move the cursor on this sub - VI Panel.  If I try to simulate the encoder, to eliminate complexity, just to create a user event every second, I don't see the problem, so it seems that it is possible, it is linked to the complexity of the system...

  Any thoughts would be greatly appreciated!

• refnum and the Boolean property nodes

  Hi guys,.

  I have a weird problem where if I create a property node and connect it to the refnum of a Boolean value, I use in my Subvi what happens with the variant data type.

  Now, I know normally it means that the Boolean control is set to a lock rather than a State of the switch. However, even when I configure the refnum of the switch on the Subvi "switch when press ' it still maintains a variant data type.

  Bascially, so what I'm asking, it is, is it possible to get the mode of Boolean data back using these property nodes?

  The main objective of this code must be able to have a "Stop executing" button on the front panel and who put an end to the Subvi, which will run at the time and return to the main program any when that button is pressed.

  The joint screws are written in Labview 2012.

  Bravo guys.

  Hello

  Home screen to the type of data in the control of reference of the Subvi.

  You may have noticed a red dot on the Sub - VI control reference entry in the main VI Boolean node.

  Also attached are the VI.

  I hope this helps.

• graph of waveform of filling via the property node

  Hello

  I want to fill a graphic waveform spirit multiple waveforms by programming. This means, the graph is the main VI, and use it in an another vi reference chart. Firstly I have to solve the correct reference waveform curve, then I use the "Value" property node The value must be the value of type variant, should be no problem. But the property node works only with table 1 d and not 2D.

  How can I fill it with table 2D programmatically? I use LabView 8.6, see attached example.

  Mitulatbati

  Hi mitulabati,

  You must specify the data type that you will be feeding to your chart, the default type is an array of 1 D.

  To do this, connect an empty 2D array directly on the graph, it will change the input to your waveform parameters and now the property node will accept this new data type.

  Hope this helps

• Problem with the Value property node (MacOS)

  Insofar that I tested it, the nodes of property Value (and value (signalling)) do not work under MacOS: value property is a Boolean value, the value (signaling) as a cluster (width, height).

  Even with the Boolean controls, the node does not work.

  Not such a problem in LV 8.6.

  Am I missing something? Is that some 'of use' ? Or just a bug?

  This looks like some sort of problem of indexing with the nodes property as somesort of corrupted installation.  What happens if you just delete the property node and recreate him?

  I filed a digital control and looked at the context menu of the list of the nodes property.  Below value and value (signs) are Visible (which would be a Boolean value) and Xcontrol, that when you bring through the submenus, the first choice is container bounds, a cluster of Width and Height.  If these 2 types of data which are located 2 below in the list match those you found.

  What happens if you take another node in property a few elements upwards or downwards in the context menu?  Fact is happen for other properties, and if so, are thereany properties who agree?

  Here's what look like my property for a digital nodes and I draggged the box up and down to show the natural order of the nodes property.  Notice that I have script installed, so there are a few other nodes property (and the blue box at the top) you may not have.

  

  PS. Verify you the signature.  Kudos button is now moved to the left since the update of the forum.

• property node

  HI (sorry for my English) I have the problem of monitoring:

  I have a vi that makes measurement it download a cluster with inside some indicators of number and a photo, I create a property node and a control for the cluster reference.

  In my main vi I create the same cluster and I join with my vi measurement using a command reference.

  the problem is... as vi dynamically change the node properties of zoom factor, left and top of image origin origin. I would like to know how to do the same thing for my core related?

• Differences with the setting 'Multicolumn Listbox' palette 'Silver' and the 'modern Palette.

  Hello.

  While I was working with these controls in a user interface, I found a strange behaviour between these two controls. Basically the 'Multi-column Listbox' control 'palette of money", which represents a 'table 2D', it appears always initialized with a null value in the first column and line 6, on the contrary that the 'multi-column listbox' control in the 'modern' palette appears not initialized.

  Is this a normal behavior?

  

  Kind regards...

  Hi Jonathan,.

  It has been reported previously in R & D as 382668 of the CAR. It is always present in LabVIEW 2012 SP1, but it has been assessed to be fixed in future versions of LabVIEW. Thanks for reporting it!

• Transfer values of ROWTYPE in ROWTYPE with different COLUMN specifications. keeping the Default_Data values

  Hello

  I have a problem on dynamically the transfer values of different columns in two variables given rowtype type.

  My intention is to transfer values from table1 into table2.

  Basically, I stated to vars of v_table1 and v_table2% rowtype, each of them contains columns with the same, and also the individual column names.

  v_table2% rowtype must be initialized with default values.

  I would like to insert v_table2 values in table2 later by practice 'INSERT INTO TABLE2 VALUES v_table2'.

  Before inserting, I need to change several values of column by different rules, but these rules are not relevant for my actual demand.

  The point is, how can I transfer the values of v_table1 in v_table2 for the hanving of columns with the same column name, without hard-coding the names of columns, because these two tables contain many columns.

  In addition values initialized with v_table2 default_data values should not be overwritten by data does not exist in the same named column of v_table1.

  Example: If v_table1. D is NULL, it should not replace the default value initialized former "Monday".

  Conditions:

  Table 1 contains the following values:

  Column name	Value
  A	'1'
  B	'2'
  C	NULL VALUE
  D	'somedata '.
  E	NULL VALUE
  F	« 3 »

  After the transfer of the values of v_table1 in v_table2, I guess that the following data:

  Column name	Value	Source
  C	NULL VALUE	Table1.C
  D	'somedata '.	Table1.D
  E	"Tuesday".	DATA_DEFAULT from Table2
  F	« 3 »	Table1.F
  G	NULL VALUE
  H	NULL VALUE

  Right now I am already able to fill the v_table2 with the default values:

  declare
    lv_query varchar2(1000);
    
    type cur_typ is ref cursor;
    rcur_typ cur_typ;
    
    v_table2 table2%rowtype;
  
  begin
      for rec in (select *
                  from user_tab_columns
                  where table_name = 'TABLE2'
                  order by column_id
                  )
      loop
        if rec.data_default is null then
            lv_query := lv_query||', null';
          elsif rec.data_type = 'NUMBER' then
            lv_query := lv_query||', '||rec.data_default;
          elsif rec.data_type = 'DATE' then
            lv_query := lv_query||', '||rec.data_default;
          else
            lv_query := lv_query||', '||rec.data_default||'';
        end if;
      end loop;
      
      lv_query := 'SELECT'||substr(lv_query, 2)||' FROM DUAL';
      dbms_output.put_line(lv_query);
      
      open rcur_typ for lv_query;
      fetch rcur_typ into v_table2;
      close rcur_typ;
  end;
  

  I have no idea how to achieve the transfer of v_table1 to v_table2 without substitute default values of table2.

  
  

  As far as I know I can find these columns with column names by querying:

  select column_name from user_tab_cols where table_name='TABLE1' intersect select column_name from user_tab_cols where table_name='TABLE2'
  

  Maybe you can give me some advice.

  Thank you very much.

  Sample data:

  CREATE TABLE "TABLE1" 
     (    "A" VARCHAR2(20 BYTE), 
      "B" VARCHAR2(20 BYTE), 
      "C" VARCHAR2(20 BYTE), 
      "D" VARCHAR2(20 BYTE), 
      "E" VARCHAR2(20 BYTE), 
      "F" VARCHAR2(20 BYTE)
     );
  
    CREATE TABLE "TABLE2" 
     (    "C" VARCHAR2(20 BYTE), 
      "D" VARCHAR2(20 BYTE) DEFAULT 'Monday', 
      "E" VARCHAR2(20 BYTE) DEFAULT 'Tuesday', 
      "F" VARCHAR2(20 BYTE) DEFAULT 'Wednesday', 
      "G" VARCHAR2(20 BYTE) DEFAULT 'Thursday', 
      "H" VARCHAR2(20 BYTE)
     );
  
  INSERT INTO "TABLE1" (A, B, D, F) VALUES ('1', '2', 'somedata', '3');
  
  INSERT INTO "TABLE1" (A, B, D, F) VALUES ('1', '2', 'somedata', '3');

  You can build a dynamic query that checks the values of all columns in the table 1,

  and if a column contains null, then retrieves the default value of the column in table2,

  or null if this column doesn't have a default vallue.

  Something like this pseudocode

  SELECT
     if column A is not null then take A from table1, else take default for column A from table2
     .....
     if column X is not null then take A from table1, else take default for column X from table2
  FROM table1
  

  The default budget can be extracted from USER_TAB_COLUMNS

  select column_name, data_default from user_tab_columns
  where table_name = 'TABLE2'
  order by column_id

• Issues related to the cell property node: Position Active for a table control

  Hello

  What determines the Position of the Active cell in a table control property node? I have this in my code and display the value of an indicator on front panel. The displayed value is always set to 0,0. Help for the property node says it's "read - only" so what defines the Position of the Active cell in a table control value?

  Define you the active cell with a property node.  Once you select an active cell, you can do this cell and single cell-specific things, things like the background value color.
