• 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 to determine if an item exists in the g_fxx table in the 4.1.1.00.23?

  Version 4.1.1.00.23

  Hello

  I have a form to tabs created manually using the APEX_ITEM package. I now apply for parole / hide a column.

  I added a request for conditional display, but since the MRU is created manually as well when the column is not there is no reference in the table of g_fxx for this column and the MRU fails with the error "no data found".

  What I "think" I want is to add a condition around the code that refers to this column to determine if this column is in the table and if we do operate the section of the code. The MRU is PL/SQL (of course).

  I am looking for is:

  IF(APEX_APPLICATION.g_f02.COUNT > 0) THEN ...
  

  What is the proper way to determine if the column exists?

  Best way to do it?

  Something not clear what I'm doing?

  Thank you

  Joe

  The g_fxx variables are associative arrays (aka the hash in Perl, etc.)

  Read here: PL/SQL Collections and records

  (it was the first link in google)

  Since it is a HASH, 1,3,5 elements can exist which is not 2,4,6.

  If an element exists

  varname. EXISTS ( element_val )

  for example

  if apex_application.g_f01.EXISTS(1)  -- see's if the first element exists
  then
  ...

• How to determine if my PC has a Bluetooth function

  Past review windows help.

  Original title - how to determine if my PC has a Bluetooth facility? __Si a, is possible to download the software to connect to my laptop? *

  Bluetooth is more than simple software - it is a hardware device that communicates with bluetooth devices.  Software alone won't do the trick.

  Go to start / Control Panel / Device Manager and see if there is no list for a bluetooth device driver.  If this isn't the case, you probably have no bluetooth.  The best way to check is to contact the manufacturer of the computer and provide them with your serial number and have them check your system to see if bluetooth is installed.  Also, if you have there is probably an icon of Bluetooth configuration in the Control Panel-, but it can be a separate program or included in other categories.  Otherwise, you need both a bluetooth compatible device with your computer and your version of Vista (and appropriate software, firmware or drivers) - more you need set up and configure - and all that is required by the mobile to establish a bluetooth connection.  Here is an article that covers in detail: http://windows.microsoft.com/en-US/windows-vista/Set-up-a-Bluetooth-enabled-device.

  I hope this helps.

• How to determine the strict reference to the table of waveform

  Hello

  I want to change the properties of a waveform by programming. I used to get all references maps of waveform a function of range in my script VI VI. Then I typecasted references to more specific class (strict-single track) after this trial I was able set properties such as data history. Everything works fine but if I add a graphic that is multiplot, that this approach does not work.

  The problem is that in the table of references, there is reference to a graph in multiplot waveform, and this reference is not possible typcast to the more specific category (strict-single parcel).

  My question is: how to determine if the reference in the table is matching the proper waveform (single or multiplot) charts.

  In the VI attached is a code that demonstrates my problem.

  Thanks a lot for the replies

  Jan

  Thank you for advice. VI point 2 from your answer, I created and it works. The solution is attached.

  If I understand it correctly. I need to know the type of chart to come.

  My first idea was to create a VI in Drop that initializes all the graphics of VI on chart type independently.

  But this solution is fine because I will only use graphics-single plot and multiplot(two elements).

  Thank you

• How to use the goto function?

  How to use the goto function in indesign javascript?

  my script begins by chekcing if the input files are present or not... If one of the input files is not present, I want the n function put an end to the operation in the display of the message tht file exists... I was wondering to use goto for tht... then how to use it? or is there an alternative to that?

  GoTo is generally frowned upon by the programmers.

  The only legitimate use of goto is when you need to escape from a nested loop.

  If you need to jump into a routine, use break or simply in return from the current function.

  The model currently used by the SDK looks like this:

  do
  {
       if(condition1 == false)
            break;
       if(condition2 == false)
            break;
       if(condition3 == false)
            break;
       doSomethingReallyCool();
  }while(false);
  

  'break' the jumps at the end of the do / while loop that always comes out when you reach the end of it (while (false))

• HP HDX X18T - 1200 CTO: RAM upgrade. How to determine the manufacturer RAM on HP HDX X18T news

  A 8 GB of RAM.  I think the upgrade to 16 GB of RAM.  (1) what is a compatible RAM and (2) how to determine exact manufacturer details RAM installed?  I would like to correspond with just over 8 GB of RAM the same, but what I can determine information system is that it has 8 GB of RAM.

  Here's what the service manual says about it:

  2 customer accessible/upgradable module slots supports supports up to 8 GB of system RAM PC2-6400, 800 MHz, DDR2 dual channel memory

  If you have 2 slots. Max memory is 8 GB of DDR2 - 800 SO - DIMM. The major modules of DDR2 were 4 gigs and a pair of them now at the retail price is about $200 if you have a few precious memory in your laptop and you have the more memory, this laptop can use. When this laptop is out, 8 GB of RAM was a fantastic thing.

• How can I create a function using variables TestStand and call from Meadow step Expression?

  In one sequence, I have dozens of prior Expressions, which are almost the same thing, like this...

  Locals.tagID = (Parameters.singlePhaseEnabled? ('L': "D") & Str (Locals.phase) & "006".

  .. and the only thing different is this three-digit string in the end ("006" may vary). How can I write a function that I can call from Meadow step Expression then it should look like this? ...

  Locals.tagID = MyNewFunction("006")

  You can not write custom expressions for commands.

  That being said, there are two options:

  • Create a sous-suite with a single step. Use a setting of the sequence as "function parameter.
  
  
  • Create a step type custom including a lower level module that implements the function. Add a step edit to allow the user to the steptype graciously change the setting.
  
  
  • Store the variable setting in a local global variable / file and change the value in each step. This will, at least, keep the same 'function' for each step.

• How to determine the amount of memory shipped on the PXI-5114

  How to determine the amount of memory onboard, I have on my PXI-5114?

  Thanks in advance.

  Hello

  I'm sorry I didn't know you already had the map.  There is a property for NO-Scope node to determine the total amount of available memory that we can then divide down to get the memory available per channel.  Please see the vi and help below:

  

  This gives a shot, just drop it in a VI that you use and if it should return your memory cards.  If you don't have a LabVIEW I can probably retrieve the purchased version by querying your serial number.

  Kind regards
