Not a number/path/refnum simple Boolean?

• Refnum control is not a number/path/refnum

  Hi all

  I'm working on a LV7.1 program. It has a control refnum on the façade. If this control is not signed by the appellant, the follow-up 'Not a number/path/refnum' will return TRUE. It's like a 'default'. But I don't know how to implement this function. I mean, I can't find a way to set the control of refnum with a default value as "not a number/path/refnum". Can someone give me a hint?

  Thank you

  Under file e / s-> constants file, there is a constant "not a Refnum". (Why under file e/s? Do not know?)

  You can change your control to an indicator, it wire up to now, the VI run once and then change things at the back (you now have not a Refnum value).  You can then make it worth stick by right-clicking on the control of data operations by choosing-> do default to the current value.

  This assumes that the control has managed to be pre-initialized with one value other than not a refnum.

• Impossible to check the FPGA reference with "not a number/path/Refnum?

  How can I check if an FPGA interface refnum is valid?  It seems (LabVIEW 2009) that "Not a number/path/Refnum?" always returns true when connected to the output of open FPGA VI reference.  I write code that needs to be able to run without an FPGA for testing purposes, so I wrapped all calls to the FPGA in a case structure that I thought would run only if the FPGA reference is valid.  Turns out that they run ever, even when the FPGA reference is valid (probe shows it has a numerical value, and the FPGA VI is running).  I guess it's sort of similar to semaphore and appointment of references that have their own special function to verify the validity, but I do not see such a function for FPGA.  I have to cast to int and check if it is not equal to zero?

  
  

• Not a number/path/Refnum? Does not work with a reference SE

  Hi all

  I am writing a LabVIEW application and check that the Switch Executive session is valid before I allow the user to validate the test to run. I connect the not A number/path/Refnum? Function to reference session SE and it connects correctly, but the output of the function is never wrong even though I see the session reference is valid and non-null. Any ideas why this is?

  Thank you

  Nick

  It was a trick to convert a reference internal in an external shared library (usually a pointer memory) in a datalog refnum strict typedefed. This safely prevents a user to connect to what anyone, but this type of refnum at the VI in question. But this wasn't really a datalog refnum and the is not a number/path/Refnum refnum, which subsystem to question the validity of a refnum to determine based on the subtype. The LabVIEW datalog Manager ever created this refnum and hence will return correctly (not one of my refnums which is currently known to be valid).

  Because of this problem the misuse of datalog refnums as a unique resource identifier has been abandoned more in recent years. Also it will work with any external resources representing pointers memory when using 64-bit LabVIEW, since memory pointers are big in this 64-bit environment LabVIEW refnums are still 32-bit.

  Collate OR if they have a newer version of the Switch Executive in gestation or perhaps already out.

• Iomega Home Media Network, Cloud edition - sharing "is not a valid path.

  I have an iomega NAS on my home network and I regularly wind up with Iperius. I now hit a question - if Iperius has treated a few files, it gets the access denied message.

  If I can go in the NAS using the storage LenovoEMC Manager, discovers an action, for example one called "Ned backups" and then click "Show content" I get the message "Ned backups is not a valid path,". "

  I can solve this problem to reboot the NAS - but there again after starting a return until you get the same problem again.

  The NAS has been working well for a number of years.

• NaN/PathRefnum? function unnecessary production responds to path, Refnum

  I found similar topics, but not quite the same thing, AFAICT.

  I'm just trying to see if an INI file exists, so I created the following excerpt:

  

  I also created a small file, put in my C:\ directory, which I have attached here.

  When I run the program of LV with C:\test.ini, my indicators come out as NaN/Path? : false, NaN/Refnum? : true

  I tried to interpret as (1) a path valid (this file exists) and (2) a refnum does not exist (even if the refnum came from a sub - VI provided by LV).

  I then replaced by control (find file) C:\test.in (sliced final 'i') and the two indicators gave me the same results. That really impressed my first interpretation, and I can't come up with anything else that makes sense.

  Thus, for paths and refnums, what happens here, if anything?

  I saw that the second test threw an error of the Sub - VI 'Open Data of Config', so I can use it for my test, but I would like to know if the NaN... function is actually good for something other than numbers. If this isn't the case, IMHO LV should change its designation on the pallet.

  That you use in a puzzling oddity of LabVIEW refnums. To check if a configuration file refnum is valid, you must not use "a given Config Refnum.vi" in the range of screw Configuration file. The ' NaN/path/Refnum?' function works only for refnum types that are built-in LabVIEW, such as queues, TCP sockets and file references. The screw configuration file are built in LabVIEW, LabVIEW rather than integrated and refnums they use are not 'real' refnums in terms of LabVIEW, they are just data wrapped as reference datalog (something for the creation of unique types of pseudo-refnum). You will see several other pallets which also includes their own functions in order to check whether a refnum is valid, such as pallets of semaphores and appointment management.

• Best way to make a simple Boolean test?

  Hi all

  Try to do a simple Boolean test, but it is more difficult than I expected.  I hope I'm missing something simple.

  I have a module of Labview code that provides a Boolean output.  I want to evaluate this value and provide the report pass/fail results.  Sounds simple, but here is what I'm running into:

  -Step OR built-in type "pass/fail Test" will evaluate the Boolean value directly with Pass = True and False = Fail.  It would be nice, unless I have situations where I need to Pass equal false.  I read a few posts talking about reversing or annulling the Boolean result, but they are all passing the result to a variable or a parameter and then evaluation outside of the test step.  This adds several layers, I don't think that I would need.

  -J' read a post that suggested that convert the Boolean value of a digital inside the code module.  It is indeed logical, but is not practical in my situation because of the scale and the implementation of my modules of code.  I use the definitions of custom type for controls and indicators a Labview project and would have to create a new control/light for everyone if I wanted to change the data type.

  -Logical extension was to see if the 'numerical limit Test' would recognize a Boolean value.  It turns out that it is not.

  -After that, I looked in the creation of a custom step type.  It would be probably the most useful, but this is beyond my current capabilities to do so.  I had as far as making a copy of the stage built in type and put in the MyTypes 'custom' directory, but I made very little progress in editing to make it work.  In addition, I read a few messages that recommend to avoid the custom step types.

  Hoping someone can point me in the right direction.  Please notify.

  Thank you

  GSinMN,

  I would enter "Step.Result.PassFail" for the Boolean output on your VI parameter (kinda like a normal part of pass/fail Test), and on the Data Source tab, you can add an exclamation at the front, for example:! Step.Result.PassFail. This will reduce to zero the value of production and use the result of this for the comparison.

  If you want to save the actual production of the VI to the report (for example), you can check the "Log" option for the setting in the module settings.

• Why do write can not be performed because the number of data channels does not match number of channels in the task.

  Possible reasons:

  Scripture cannot be performed because the number of data channels does not match number of channels in the task.

  When writing, provide data for all channels in the task. You can also change the task so that it contains the same number of channels as the written data.

  Number of job channels: 8
  Number of data channels: 1

  Lama says:

  The DAQmx vi writing gives me the error. If I run a single channel, isn't a problem. Multichannel gives me error.

  You are funny! Why tie yourself to work VI (single channel) instead of one that gives you errors (multichannel)?

  (If your car does not work, you bring car your wives to the mechanic, right!)

  What is the exact text in the multichannel 'physical channels' when you do the AO control?

  Lama says:

  I did a sequence to ensure that each function has been run in the correct order. Wouldn't a race condition.

  All you have to do is wire the 'start of task' error at the entrance of error of the DAQ assistant and then back to 'stop task' and things will run in order. Guaranteed! Think the stream! Everything else can run in parallel or the order is irrelevant.

  First convert the sequence stacked to a sequence of plate, remove the flat sequence and add the mentioned son. Now, do a "cleaning pattern.

  A when stacked with the inhabitants of the sequence is one of the worst construction you can possibly do. It makes the code difficult to follow, impossible to maintain, difficult to debug.

• Applications Windows XP Startup - Bug: the .exe file name only, not the full path

  Using Windows XP, run-msconfig-startup online online, only the name of the Executive file of the Applications that load and boot at startup are shown - this name sometimes not easily indicates he belongs as to which Application.
  Therefore, it becomes difficult to decide to uncheck (stop autoloading at startup) or not - unless the full path to its location is revealed. But this small window no poster not the full path - even if the mouse pointer is hovered over an entry in the list of applications.
  Third-party software (AnVir Task Manager Free) displayed the full path when the mouse pointer is moved to an entry.
  Microsoft should take the queue and improve this Service / installation / functionality, please.

  On my Windows XP, there is a 'Command' column / window for the start of the tab that displays the full path to the file.  If this column is not wide enough to show the entire path, place your cursor on the line that separates the column header in order for the column heading 'Image '.  The cursor turns into a line with arrows pointing to the left and right upright.  Click and hold the mouse button down and drag to the right.  The column will expand and a horizontal lift will open down to scroll all right.

• Dialog results 'not a number '.

  Hello! I am new to InDesign scripting (to date) and has difficulties with the help of dialog box results in my script. The script that I put in place creates calligraphy guide line to the bottom of a page and got this works well but then wanted to be able to specify the distance between the lines in a dialog box, rather than in the script, and it does not work now.

  I know that everything from line 43 down works if I remove the dialog box and create variables using parseInt() rather than pulling them from the box of dialogue, but as soon as I try to use the values of the dialog box, what happens with error on line 60 30491 that ascenderHeight is not a number (and so he can probably use it to calculate in geometricBounds). I tried to convert a variable to test entire under line 43, but it makes no difference. Initially, I used the measurementEditBox as in the tutorial of InDesign scripting, but thought that the whole it would remove any excess baggage. If someone could let me know where I am going wrong, I would really appreciate it!

  Without going into all of your script, let's look at your dialog box:

  Take the code to your dialog box and copy it to a separate script.

  Now instead of calling the construction guide, replace this line with a test to check the values of variables:

  [ascenderHeight, xHeightmm, descenderHeight, slantAngle];

  When you run the script, you will see where is your problem: the result is:

  Result: [object IntegerEditbox], [IntegerEditbox object], [object IntegerEditbox] [object AngleEditbox]

  You have found a reference for widgets dialog box, not the edit value.

  Add .editValue to each of your definitions of variables so that they read:

  var ascenderHeight = ascenderHeightField.editValue;

  var xHeightmm = xHeightmmField.editValue;

  var descenderHeight = descenderHeightField.editValue;

  var slantAngle = slantAngleField.editValue;

  This should solve your problem.

  Bottom line: when you encounter problems, isolate the code and assess the results.

  I hope this helps.
