• Write the previous values DBL

  Hello

  I work with LabVIEW 2013. I'm receiving the channels of a robot and the analysis of the data and plot the position real vs commanded position. When the robot meets and error, it sends LV and messages. All string parsing is done in the same place, so the graph just to draw all 0 when it receives an error.

  I have it such that when it detects an error, it lights a Boolean value. What I have to do now is to write the previously known values for the "true position" instead of setting them to 0. Is this possible?

  A snippet of my code is attached. I get this channel 4 times per second.

  Thank you

  Here's a quick example. If an error occurs, use the old value of the FN, if not use the new string data.

• Table expanding: calculation of the difference in the value of the previous row

  Hello

  I'm a complete newbie to LiveCycle Designer (ES2) and created under the document with a table in full expansion.

  Shared files - Acrobat.com

  My goal is to make the friendly form by adding a calculation in the field "Twist" that calculates the difference of the current line to the previous row.

  I have no idea about Java Script, I'm afraid and also do not know if this is possible at all, so it's probably a bad idea after all.

  The reason for setting up as a table expansion is so that the form can be used for all 32 instances form would be used for (they all need different number of rows in total).

  The calculation will start in row 2 (Checklist.Table1), take the value of the entry in row 2 torsion and calculate the difference in the value of the twist entry in row 1.

  Then, in row 3, it calculates the difference between the value of the twist in the row 3 tier 2, etc.

  So subtract the value of the field in theⁿ with the value line online^n-1 or something in that sense.

  Is there anyone at all who could help me with that at all?

  I would be very grateful for any advice you could give me.

  Thank you very much!

  Mathilda

  Hi Matilda,.

  Try this code;

  if (Row1.index > 0 && !Row1.resolveNode("NumericField4[0]").isNull)
  
   var prevTwist = Table1.resolveNode("Row1[" + (Row1.index - 1) + "].NumericField4[0]").rawValue
  
   var result = Math.abs(3000 / (Row1.resolveNode("NumericField4[0]").rawValue - prevTwist));
  
   this.rawValue = result;
  
   this.rawValue = "";

  Try to follow these steps:

  1. in the database table to add the new column "JOIN_COLUMN" and add the new sequence "JOIN_SEQ".

  2. Add this new column in the entity object. (You can add this in entity object by right clicking on the entity object and then select "Synchronize with database" then the new column and press on sync)

  3. in your bookmark create button to create only one line NOT 2 rows.

  4 - Open the object entity--> java--> java class--> on the entity object class generate and Tick tick on the accessors and methods of data manipulation

  5 - Open the generated class to EntityImpl and go to the doDML method and write this code

  Very interesting journal. It seems that the pilot who seemed to be a rootkit is a false positive with a strange string. Or a rootkit is present, but we cannot detect. avastMBR crashing may be related to something else in all cases, however.

  First of all, can you please uninstall Daemon Tools Lite + alcohol?

  In addition, subsequently, c:\windows\system32\drivers\sptd.sys is listed and loaded into your list of modules; SCSI pass through Direct Host - Daemon Tools (BSOD known issues with Win 7 and 8). Please remove it as soon as POSSIBLE with the uninstall tool - http://www.duplexsecure.com/en/downloads

• Hide a field value based on the value of the previous row

  I need to read the string before the underscore (_) and show that the value in the 1st row for the field of Value1. For example, if the previous string (ABCDE) is equal to that of the second line I need to hide the value (100) on the field of the value1.

  Sample data:

  Report ID	Val1	Val2	Val3
  ABCDE_01	100	200	300
  ABCDE_02	100	250	350
  XYZ	500	60	28

  Final results:

  Report ID	Value1	Value2	Value3
  ABCDE_01	100	200	300
  ABCDE_02		250	350
  XYZ	500	60	28

  I am using code below but error.

  <? If: xdoxslt:get_variable($_XDOCTX,_'x')! = substr (REPORT_ID, 0, instr(REPORT_ID, '_', 0) - 1)? >

  <? Value1? >

  <? end if? >

  <? xdoxslt:set_variable ($_XDOCTX, 'x', substr (REPORT_ID, 0, (instr(REPORT_ID, '_', 0)-1)))? >

  You can use this condition instead:

  It will manage both of your cases.

• How to get the sum of the first row in the previous row?

  Dear gurus... I need to get the sum of a column of the first row of my result set to the previous line based on a condition. I read analytical functions for this but they provide the sum of the first rank to Current Row through declaration "rows between Unbounded preceding and current line. Y at - it a statement that calculates the sum as "rows between Unbounded preceding and previous row?

  If you do not explicitly give a windowing clause, then you get the default windowing clause you indicated.
  If you want another clause of windowing, ionclude in the analytic function call.

  Y at - it a statement that calculates the sum as "rows between Unbounded preceding and previous row?

  Yes. The correct syntax for "Previous rank" is «PREVIOUS 1»

  ...  ROWS BETWEEN  UNBOUNDED PRECEDING
              AND        1          PRECEDING
  

  For more information, search for "Analytic Functions" in the manual of the SQL language:
  http://download.Oracle.com/docs/CD/E11882_01/server.112/e17118/functions004.htm#sthref917

  I hope that answers your question.
  If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all tables and also post the results desired from these data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.
  You will find the answers better faster if you always provide this information whenever you post a question.

  I just saw Etbin responses.
  As usual, Etbin has a good point. If the column that you are basically cannot be NULL, then it is probably easier to subtract the total current line and use the default windowing clause.
  Even if it can be null, you find may be easier to use this approach.
