• Check if the variable is null / not affected

  Hello

  I've been unable to find explicitly for an answer to the question how to check if a variable is null or Unassigned or not defined. As some analog to java fi (var == null).

  The variable in question is of type xsd: Integer. I use the assign activity where I use oraext:lookup - table. If the (integer) value is not found in the database, then the variable remains unaffected. However, I am of ideas of how to do to check if it's still not affected or not

  Thank you!

  To check if the value of a variable (in bpel) is null or empty, I think you can use this expression - bpws:getVariableData('variable') = "(just two quotes together), in a condition of switch-case / if-else.

• How to check that the variable 'does not contain' value?

  Hello

  I use CP 7.0.1.237.

  We want to use the widget text box for a custom quiz and verify a response. While we understood how to check the existence of certain key words, we are not able to find a way to check that the content does NOT contain certain keywords. For example, we want to ensure that the text entered in this widget does not contain a "Transformation" and "Non-compliant.

  Is this possible at all?

  Thank you

  Anthony, it works perfectly. Created this conditional action with 4 decisions. I used the interaction of training text scrolling in CP8 (because now you can control the variable - which means I might have a Reset button):

  First decision:

  

  Second decision (the third is similar to the following)

  

  Fourth and final decision

  

  I put the variable words (v_first... v_fifth), it's a reflex I use since I shared actions that much. The variable associated to the ETB (you can now reset an empty var in CP8) is v_TextArea and the Boolean value that will decide if positive feedback (StarOK) should be shown is v_TA_OK. If you want to display a negative feedback, put this in the ELSE part of the final decision.

  FYI: it took 15 minutes, including the creation of assets and the variables and tests. Personally I would have needed more time to do it in JS, but that's just me.

• How to check if the variable (of type uint) has a value or not?

  Hi all

  I'm just trying to write an instruction conditional to check if my uint variable has a value or not.  I tried to check "null" and "undefined", but without any luck (see below)

  private var _tempIndex:uint;

  ...

  ...

  If (_tempIndex! = null) {}

  code here

  }

  had an error with that one, then tried

  If (_tempIndex! = undefined) {}

  code here

  }

  had an error with that as well.

  So, how can I check if a variable has been assigned a value or not? Any ideas? Thanks in advance!

  Mike

  A uint always has a value between 0 and 2 ^ 32-1 inclusive. It cannot store a value 'no' as undefined or null. If you declare a variable of type uint without assigning a value, it is given a default value of 0.

  You need to maintain an indicator Boolean separate or to use a type of data larger such as number (which can store NaN), object (which can store NaN or null), or * (which can store a value, including NaN, null, and undefined).

• Check if the variable is in the Recordset

  I have a Recordset queryparam in my page (let's call it rs_authorized), and I have a form submitted value (let's call it form.county).  I want to make a statement < cfif > based on the variable either or not in the recordset object.

  I tried...

  < #form.county # cfif EQ < rs_authorized.county_name # >

  but he acknowledges that if the first value of the Recordset.

  I tried...

  < Cfif ListFind(#rs_authorized.county_name#,#form.county#) >

  But even once, he acknowledges that if the first value of the Recordset.

  I tried...

  < #form.county # cfif IN (#rs_authorized.county_name #) >

  but I get an error saying that it does not recognize the word 'IN '.

  Any ideas?

  Depending on what exactly you're trying to do here, you might have to take one or more of the following:

  (1) use a full qualified reference of queryName.column.rowrecord set:

  I.E.

  #rs_quthorized.county_name [2] #.

  (2) loop through the recordset object to search for all lines.  or buildings do it is rather easy to do, but nothing prevents you from using any mechinism looping you care to use.

  (3) use the valueList (queryName.column) to put all the date of a column in the folder defined in a list.  This, combined with the listFind() or listContains() function will allow you to quickly search for a unique value.

  Hello

  Thanks for the reply - I received a system clock analog once I've run 'xclock' command as long as user root, but received an error message when even tried with the "oracle" user

  What EXACTLY do you (differently?) between the time where you succeed as a 'root' & fail as 'oracle '?

  I can assure you that xclock will fail if you use "su" as below

  Su - oracle

  You need TO connect DB Server system DIRECTLY as user 'oracle' with X 11 active transfer OS

• How to determine if the variable exists?

  I need to find a way to determine if a variable exists.  Because if I don't and evaluate a variable that does not exist, I get error.  This is why I need to do this.  I need to print only the failures in the sequence and the problem is that I can print only the failures that causes failure of the sequence.

  I have reduced that there is a Boolean status in the list of TS results. StepCausedSequenceFailure.  The question is this variable exists only when the step caused sequence failure checkbox is checked, otherwise this variable is not in the results.  Thanks for help.

  Use PropertyExists ("Locals.ResultList [x]. TS. "" "StepCausedSequenceFailure"), where "x" is the index of the step that interests you as a precondition to any approach that will access this value. "

  I hope this helps.

• How can I check if the counter entry is synchronized with the analog output?

  Hello

  I'm working on an application for counting photons.  I use two channels of analog output on a PCI-6713 card to send a frame model to a set of XY scan mirrors.  I then a photon count unit that emits a TTL signal when the photons are detected as a result of this raster analysis.  I then use a surfboard USB-6211 to count the edges on this TTL signal.

  I have problems that seem due to synchronization problems.  I use the sample AO on the PCI-6713 card clock like the door of my meter on the map USB-6211.  I use a trigger to start digital to analog output and a trigger of arms for the entrance to counter early. Is there a way to check that the analog output and counter entry of start of operations at the same time and are are synchronized?  I basically want to monitor and compare the ao real sample of the PCI-6713 card clock door signal used by the jury of the USB-6211.  I was able to export the sample AO clock and watch it on my oscilloscope, but not the signal from the door of the USB-6211.

  Thanks for your help,

  Brian

  Update... It turns out that there is no problem of synchronization between my meter input and the analogue output.  There was a difference of impedance when I connected my unit of counting photons to my USB-6211.  This caused an error variable count rate.  After accouting for this shift, the problem disappeared.

• Maybe stupid question from new user: that can be done to get the variables displayed in the information tab variables?

  I've been a user of LabVIEW (2011) for about 1.5 years now and just got ahold of TestStand 2014 to try future test as a structure for our needs.

  I am using on and off for about 3 days and there is something that has been driving me nuts.  When I launch a sequence, and that the report comes at the end, there are three tabs on it: report, steps and Variables.  Report and the steps are exactly what I expect to see.   However, the Variables tab is always empty.  Nothing that I found via my technique of checking everything in menus that looks vaguely related and right click things on many items and these menus for other vaguely related things as well.

  I tried looking for references to it, and all I get is the "Main" variable tab you see when you change the sequence, not the one that appears on the report.

  See arrow in the image below:

  

  I suspect there is something incredibly obvious that I'm missing, but it's driving me crazy here...

  You won't see that filled when a run is complete. The variables are useless at this time here.

  If you want to see this populous tab to suspend execution in the middle.  Or a breakpoint.  Then you can watch the variables at run time.

  Kind regards

• How to change the value of string clustered, to implement using the node value of property instead of writing directly on the flow of data or using the variable

  new to labview :-) and I have a problem when I want to change the value of a string in bunches, and I want to implement this using the node value of property instead of writing directly to the stream or by using the variable, enclosed is the picture.   No matter, I have change in cluster (control) or value of Popery out (indicator) cluster, the value (sensor 7) dataflow keeps unchanged even I gave the new value by value of property node. Thank you to give me some advice about this.

  

  Hi GerdW

  Thanks a lot for your answer. The reason I'm stubbornly tring to break the flow of DATA is: we have a test system that have about 100 screws, they have a few connected flow, some of them will be unbundling a cluster dataflow chain to check the value in order to make the different cases.  Now I want to insert user event by changing the control and influential cases during run time.

  As I initially uses a global variable (to control cases) instead of unbundle string data flow, it works well.  But then, I found there are a lot of screws that are using the string unbundle.  One of the 'lazy' means, I tried is to change the value via the property node (because that way, I did not need to find all the places where using the unbundle string and replace them with the global variable), then I noticed a problem with "dataflow", the value in the stream of cluster in fact will not be changed by changing the value of the property node.

  I did a test with VI simple (like the picture in last post), and after reading your advice, I tell myself that I need to understand the concept of "DATAFLOW" in labview, it seems that my "lazy" way can not work in this scenario.

  I have attached the criterion VI here, have you furthur suggestions on what I can do in this case?

  Mant thanks!

  The collections have some counts; scalars don't.

  l_numbers is a collection, so you can see the number of items contained in it like this:

  DECLARE

  List_of_numbers_t TYPE TABLE IS NUMBER;

  l_numbers list_of_numbers_t: =.

  list_of_numbers_t (1,2,3);

  BEGIN

  DBMS_OUTPUT. Put_line (l_numbers. (COUNT);

  END;

  /

  l_numbers (1) , however, is just a scalar NUMBER, you can't use COUNT on it

  In other words, l_numbers (1) is the number 1, so we can not say

  DBMS_OUTPUT. Put_line (l_numbers. (COUNT);

  for exactly the same reason that you can't say

  DBMS_OUTPUT. Put_line (1. (COUNT);

• Value of the variable of LMS

  My variable of user customized course users and it is important that its current value is stored in the LMS when the user leaves the course, but no matter, I make only the initial variable value is stored (when I check the LMS the value that appears in suspend_data is the initial value).

  I joined the variable in the scene to be sure which is the value, when you exit the course and do not rely on the output.

  Is there something I need to do to get the stored value for the LMS?

  I think the question can be suspend data.  SCORM 1.2, I think that you are allowed to 4000 bytes.  CP uses a lot of it.  If you have more than 100 pages in your cptx, you can already invade this limitation.

  Try the SCORM 2004 edition (which allows 64 000 bytes to suspend data I think) and tests in the clouds of SCORM.

  If that works, you can be sure you're overtaking of SCORM 1.2 suspend the limits data.

• Storage in double-layer in the variable 'function object is undefined.

  Im trying to write a script that duplicates and reflects a layer in the central axis. It is also my first script in sequels to try to get the feel for it.

  However, I'm not sure what the problem is. Is the problem with storing the layer duplicated in the variable? Or I use the object/processing of scale it the right solution.

  #target aftereffects
  
  var center = 3840;
  var layers = app.project.activeItem.selectedLayers;
  
  for (x in layers) {
      var old_position = layers[x].transform.position.value;
      var new_position = (center-old_position[0]) + center;
      var new_layer = layers[x].duplicate();
      new_layer.transform.scale(-100, 100);
      new_layer.transform.position(new_position, old_position[1], old_position[2]);
  }
  

  Check in After Effects script guide documentation of the objects of the property.

  Properties must be defined with the function setValue and need for arrays as arguments.

  scale.setValue ([-100, 100]) instead of scale (-100, 100);

  etc.
