• LabVIEW Unit Test Framework: workaround for forbidden control characters label?

  Hello

  I am using Unit Test Framework of LabVIEW and he tells me that I am not allowed to use the unit as [Celsius] card in my labels of control:

  «Control's label may not contain the following items: \n, \r, tabs, table holders, name and decimal separators delimiters.»

  In the VI under test contain [] or /. »

  Rename these labels is a difficult option for me because the format of the units in brackets is on our company agreements.

  Can anyone think of a work around so that the test framework ignores these labels?

  Thank you

  Peter

  There was an exchange of views on these "Naming Conventions" a general consensus was arrived at, it became obvious that the best methods for the controls and indicators is to use short "Lables" and put to amplify the info in the caption showing the legend on the FP and not the Lable.

  for example

  "Temp".

  "Temperature [Celsius].

  This saves a lot of space BD when buldling / unbundling or using VI Server refs, always give the user all the information they need, and help displays the legend if there is one.  It even allows to change the default value (0) without messing up any type defs.

  In your case the Framwork UT would be happier if you have taken this approach.

• change the text unit-error bounds 1128

  Hey everybody,

  I develop a VI that uses the native power of LabVIEW units to do all the conversions of my numbers.

  Here my question, once variables are defined for a control when editing can I change the text of unity to something not related to execution in order to prepare my indicator for a different signal? For example, lets say channel 1 is a temperature for Test1 so programmatically feray Cdeg conversion and back without problem for LabVIEW. For Test2, the same VI is used, but now the channel 1 is a pressure. Programmatically change my of feray indicator units now a unit of pressure psi, atm or bar? I am getting error 1128 "input unit is not compatible with the device current." even if the device is correct when it is entered at the time of publishing.  Any thoughts?

  Thank you

  Hi Lucie,.

  No, you cannot change the type of unit when running. This will be fixed at compile time. You can modify other representations of the same physical property (as the Pa to the bar or some obscure lb/po2 of pressure).

  An old trick when using units:

  You can use '$1' as a control unit. Using a function to "Convert the unit" also set to "$1"you can then strip the unit." If your Subvi accepts any control unit connected-, but that does not solve your problem of perticular

• Creating a table of automatic indexing of loop for

  Hello and greetings from a newbie to LabView,

  In my program, I want to write several orders via VISA and read them in order. I created a table of command and auto-indexé to a loop for.

  I want to receive a table of responses, in the order they were read of course. However, I'm not sure what is the best way to do it.

  I'm sure that the solution is simple but have been unable to find one. I have attached the vi for reference. (VISA vi reading is part of the LabView unit driver), which works, but looks like a unmodular approach and inelegant.

  Thank you!

  Simple, you can auto-index the output!

• C4280 Solution Center Software refuses to see all-in-One installed

  OK, my fine ran C4280 forever, all of a sudden won't scan from Solutions center - get various errors - communication error with the device, no device installed, the software is not installed, cannot communicate, software missing etc. ad nauseam. Have reinstalled, uninstalled using all level 4 with rotation of MSCONFIG just turned off and it still don't load correctly 5 different downloads of HP or the CD. The problem is in the part somewhere, scanning software as I can scan WIA and painting (which uses the WIA) Photoshop and most of the programs with the exception that the program offers you to use the scanner software, I get a message similar to "not installed". Obviously not a problem of USB that I can scan fine in WIA and obviousl it is two-way connection, but solution center not scan. He'll work for the copy function, but hit the photo or document scanning time and error message. Any ideas away from throwing the entire unit. Completely updated XP3 to day running.

  I was contacted at last by the advanced support tech, unfortunately, he wanted me to reformat my hard drive and reinstall windows XP, which was not an option. Instead, I got creative - uninstalled "Solution Center"through the control panel and all HP, including HP Photosmart 2.0 software. Put the cd in and sailed to uninstall (rt click on the disc in the cd drive and open, search for folder util, open. find the ccc folder and open, uninstallers are listed as "uninstall_L1, 2, 3, 4") used level 1, then 2, then 3, then 4 programs uninstall and rebooted. Then, I downloaded the HP Photosmart 3.5 software and installed by itself, as the prior installation would not allow the scanner to connect (TWAIN error absent). Then downloaded the package "Solution Center" and the software for a C6280 and installed, although it would not recognize the C4280, I continued with the installation by checking I would connect later. I unplugged the PRINTER from the power from the USB and restarted. After restarting, connected to the PRINTER and then the USB, windows recognized as new hardware, let the Wizard do its thing until he asked for the CD, put the old CD in the drive and let it copy the files he wanted, then came and asked to install a HP screen, I chose "custom" fist and then next sceen asked for auto or advanced , has chosen peak and let it go from there (most of the programs in the list showed already "installed"). When he finished I had 2 digital imaging monitors on my sys tray, rebooted and then alone. Solution Center now opens, communicates with the scanner and the works - if a little slowly, but it is 100 xxxxxx software not software of xxxx. 90.l transmit the tech boys so that they do not force others to reformat and destroy their systems without reason.

• Customize the tool tip Message

  Hi all
  
  I have a Date component on my page and basically I'm trying to disable the Saturday and Sunday from the calendar that I made using the disabledDaysOfWeek attribute. In doing so, I get a message by default tool tip (in bold) who says:
  
  Example: 11/29/1998
  Enter a date that falls on one of the following days: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday
  
  So I want to customize it by deleting the Saturday and Sunday of the above message. I tried shortDesc which did not work, instead of this displays the typed message (United Nations in bold) with the "BOLD" above.
  
  So, can I do this? If this isn't the case, I would like to disable this tool tip message.
  
  
  < af:inputDate value = "#{bindings." SelectDate.inputValue}.
  label = "" Date preferred: ""
  required = "true".
  shortDesc = "#{bindings." SelectDate.hints.tooltip}.
  Binding = "#{backingBeanScope.beanName.ID1} '"
  ID = "id1".
  disabledDaysOfWeek = "Sam Dim" >
  < f: validator binding = "#{bindings." SelectDate.validator} "/ >"
  < af:convertDateTime pattern = "#{bindings." SelectDate.format} "/ >"
  < / af:inputDate >

  Hi Saif,

  Saturday and Sunday, must be removed by default if you set disabledDaysOfWeek = 'Sam Dim. " I had a similar request in one of my projects.
  I am able to remove the ToolTip text of tool on Sunday. Here is my code:

  *
  disabledDaysOfWeek = 'Sun '.
  * value = "#{pageFlowScope.pickUpDate}" / > *.

  And here is a picture showing Sunday being removed from the balloon. http://ADF-use-cases.googlecode.com/files/date.PNG

• Control of canoe of unit tests in LabVIEW on ActiveX

  Hello

  I want to run the unit tests of canoe in LabVIEW using ActiveX.

  EnvVars and sysVars in canoe handling was not a big deal, and there are plenty of examples here.

  But the unit tests of handling is quite difficult. Canoe help file shows this way in the object hierarchy:

  I solved the problem with the help of vector Support. They sent me the following c# example:

              CANoe.TestEnvironment mTestEnv = (CANoe.TestEnvironment) mTestEnvs [1]; Test environment (file *.tse)

• Problems of LabVIEW with Test Unit under lvoop

  Hello

  I try now provided with LV2012 with a LVOOP code Unit Test infrastructure but seem to be a few problems.

  I have built a unit test for a base class in the attached draft who is the source of class (it is another class in the project as it is an example of a method for recovering, but it is not used in the unit test). My problem is that I get results that fail for one of my tests, when I think they have to work.

  Basically, the unit test is configured as follows

  Case 1) test the VI without installation VI and ensure proper operation default values

  Case 2) test VI by setting specific values in the test in VI of disassembly and also check the single release of "Source Method.vi" configuration VI

  Case 3) Test of the VI with the VI of installation using the default values and confirm them through the VI of disassembly

  When running case 2 fails and indicates that disassembly of the VI return values by default not those fed to the installation VI. I don't see why.

  As per

  

  Any suggestions?

  All the best

  Hi David,

  The behavior you describe is planned. When you first call the 'Source_Method.vi' by using the 'SourceAccess Unit Test Manual.vi", the"Unit Test Manual.vi SourceAccess' creates and instance of the "Source_Method.vi". In this specific case of the VI it will boot with the default values but will then retain the values passed by the "Unit Test Manual.vi SourceAccess' until the project we closed, or specifically tell you to reset defaults. Whenever she is called by 'SourceAccess Unit Test Manual.vi' it will access this instance of it. If another instance of the "Source_Method.vi" was created by another parent it would be initialized with their default values, until crushed by the top-level VI calling. Then would he behave exactly as the instance created by the "Unit Test Manual.vi SourceAccess". Whatever your type typedef and its configuration, as long as everything is connected correctly, this should be the expected behavior when you configure things through object-oriented programming in LabVIEW.

  I hope this information is useful to your application. If you want to see a LabVIEW example that demonstrates this behavior, you should consider referring to parts of the ReferenceObject.lvproj. It is found by searching in the example finder LabVIEW object-oriented. This is accessible via

• How to create a strictly typed control refnum using LabVIEW scripts

  I want to use LabVIEW to create a strictly typed refnum control that is bound to my custom control (a defined cluster), but I'm not familiar with scripts and can't see how to do it.

  If I create a new object of VI, with Refnum of control as the Style, how can I give my custom class object VI control terminal? When I try to use a reference to my control.ctl file customized (using the Open VI reference) I get an error: 'error 1057 occurred... ". Type mismatch: object cannot be cast to the specified type. »

  Alternatively, if I create a new Refnum of control as above, using a standard Cluster as the object of VI class, how I can convert this refnum control to a strictly typed refnum, which is related to my custom cluster control type?

  Thanks in advance for any advice,

  I tried, and as usual, things were slightly different.  The big problem is that a constant control reference becomes a node, not a constant, so cannot be converted to a control.  The good news is that you simply move to the front of the new control, as you would in the dev environment.  Here is the raw code (always needs cleaning to close the refs and add save of the new control, and more, you don't need to show the FP control if you do not want).

  

• Not able to add units in LabVIEW?

  Is it possible to add units of LabVIEW?  I found the units available in LabVIEW and one I need is not listed.  I would like to add torque (lb - ft or N - m), as well as pressure (inches H2O).  When I display the unit label under items pulled down on the front panel and then try to type "pi" for foot book or even "lb - ft" for feet as an exclamation mark books displayed in the label.  I guess this means that the units I try to enter is invalid.

  LBF ft will convert Nm.
