Additions to the LabVIEW Help
Documentation CorrectionsSupported PlatformsLabVIEW 8.2.1 supports Windows Vista/XP/2000. LabVIEW 8.2.1 does not support Windows Me/98/95/NT. Note: Support for Windows Vista includes both the 32- and 64-bit versions of the operating system.Refer to the LabVIEW Release Notes for a complete list of system requirements.Installing LabVIEW 8.2.1If you have LabVIEW 8.2 installed, you can install LabVIEW 8.2.1 without first uninstalling LabVIEW 8.2. Note: Because LabVIEW installs 8.2.1 over 8.2, you cannot have both LabVIEW 8.2 and 8.2.1 installed simultaneously.If you do not have LabVIEW 8.2 installed, you can install LabVIEW 8.2.1 without first installing LabVIEW 8.2.Refer to the LabVIEW Release Notes for more information about installing LabVIEW.Installing Another Language VersionIf you have another language version of LabVIEW 8.2.x installed on your computer, uninstall that version before installing the new language version.Installing LabVIEW SilentlyYou can control programmatically which features in the LabVIEW distribution to enable or disable for installation. You therefore can install a subset of the LabVIEW distribution silently. Refer to the silent_install.txt file in the Bin directory on the LabVIEW CD for more information about installing LabVIEW silently and selecting which features to install automatically.LicensingLabVIEW relies on licensing activation. You have a temporary license for a 30-day evaluation period. If you do not activate the LabVIEW license, LabVIEW operates in evaluation mode, by default, for a 30-day evaluation period. When the evaluation period expires, you must activate a valid LabVIEW license to continue using LabVIEW. To activate the LabVIEW license, use the serial number you received as part of your installation package.If you are upgrading from LabVIEW 8.2, and you install LabVIEW 8.2.1 without first uninstalling LabVIEW 8.2, you do not need to activate the LabVIEW license.Refer to the LabVIEW Release Notes for more information about licensing in LabVIEW.Known IssuesInstallation
[*]If you uninstall LabVIEW 8.2.1 and a previous version of LabVIEW remains on the system, the previous version of LabVIEW might try to repair itself the next time you open it. The repair process might remove any patches you installed for that version of LabVIEW. Make sure to reinstall any patches you have on the system after the repair finishes. Refer to the KnowledgeBase at ni.com for more information about correcting this problem.
[*]If you install LabVIEW 8.2.1 and then install a previous version of LabVIEW on the same computer, Windows Explorer crashes if you use Windows Explorer to perform an operation on an LLB. As a workaround, select Tools»Options, select Environment from the Category list, remove the checkmark from the Enable Windows Explorer for LLB files checkbox, and click the OK button. Display the same Environment Options page again, place a checkmark in the Enable Windows Explorer for LLB files checkbox, click the OK button, and restart the computer.
Compatibility
[*]LabVIEW 8.2.1 is not compatible with NI TestStand 3.1 and earlier. Refer to the National Instruments Web site at ni.com to access the Upgrade Advisor and purchase NI TestStand 3.5 or later.
[*]The NI Publish-Subscribe Protocol (NI-PSP) networking technology is incompatible with the Windows XP Service Pack 2 and the Windows Vista firewall. You must disable this firewall or add the related services as exceptions for networking to function correctly. Refer to the KnowledgeBase at ni.com for more information about this issue.
[*]If you have Windows XP Service Pack 2 or Windows Vista installed, a Security Alert dialog box appears when you launch LabVIEW or the NI Example Finder for the first time. If you select the Keep blocking this program option, the LabVIEW VI Server, LabVIEW Web Server, and any server written in LabVIEW cannot accept incoming connections from a remote computer. Select the Unblock this program, despite the security risk option to configure your computer to launch LabVIEW without any changes in functionality. Refer to the KnowledgeBase at ni.com for more information about correcting this problem.
[*]If you previously installed the LabVIEW Report Generation Toolkit for Microsoft Office and you upgrade to LabVIEW 8.2.1 without first uninstalling the toolkit, the Report Generation Toolkit VIs break. Refer to the KnowledgeBase at ni.com for more information about correcting this problem.
VIs, Express VIs, and Functions
[*]The links to subVIs from the labview\vi.lib directory might break when you use File»Save for Previous Version to save application VIs for a previous version of LabVIEW. Right-click the subVIs and select Relink To SubVI from the shortcut menu to relink the subVIs.
[*]If you move a VI that contains Advanced Storage VIs to a LabVIEW development system with a different language, the VI does not work because the object types and property names do not match the names in other languages. To correct this problem, use the internal, language-independent object types and property names. Refer to the KnowledgeBase at ni.com for more information about correcting this problem.
[*]If you create a new, untitled VI while using the Storage VIs, the numbering of the untitled VI might be inconsistent.
[*]The Storage VIs do not support the extended-precision, floating-point data type. If you wire this data type to a Storage VI, LabVIEW returns a compiler error when you run the VI.
[*]The Delete Data VI does not work with .tdm file, the size of the file does not change, but you cannot access the data you try to delete.
[*]The Sound File Read VI uses large amounts of memory to read an entire .wav file piece by piece rather than in one large file.
[*]The Array instance of the Sound Output Set Volume VI does not use the volume input to set the volume on a per-channel basis. Instead, this VI uses the first element of the volume input as the sound level for all channels.
[*]The Read From Measurement File Express VI returns an error if you call it on the same file multiple times, which makes using this Express VI in a subVI problematic.
[*]If the Database Connectivity Toolkit is installed, you cannot place the Database Variant To Data function on the block diagram. Refer to the KnowledgeBase at ni.com for more information about correcting this problem.
[*]If an example VI from LabVIEW 7.x or earlier opens another VI by specifying the example VI name as a path in the Open VI Reference function, you receive an error when you run that example in LabVIEW 8.x. Remove the String To Path function wired to the vi path input of the Open VI Reference function to correct the error.
[*]If you configure a Call Library Function Node to call a LabVIEW DLL, place a checkmark in the Specify path on diagram checkbox on the Function page of the Call Library Function dialog box, and select Run in UI thread in the Thread control, LabVIEW hangs when executing the Call Library Function Node. To correct this problem, select Reentrant instead of Run in UI thread in the Thread control. If you configure the Call Library Function Node to call a DLL written in C with these same settings, LabVIEW works correctly.
Block Diagram Objects
[*]If you wire a hex value greater than x7FFFFFFF as an unsigned, 32-bit integer to a Formula Node, LabVIEW coerces the value to 0.
[*]If you register an ActiveX event, you must unregister the event explicitly. Otherwise, memory leaks might occur because the ActiveX control does not know that the client has disconnected.
[*]When you select Tools»Compare»Compare VIs and use the Compare VIs dialog box, LabVIEW does not display differences between values of cluster constants.
Environment
[*]A blue field does not surround the palette icons for Express VIs from LabVIEW 7.x and earlier that you open in LabVIEW 8.2.1. For example, if you use a LabVIEW 7.1 toolkit in LabVIEW 8.2.1, a blue field does not surround the icons for Express VIs on the toolkit palette. You must mass compile the Express VIs to display the blue field around the icons.
[*]If you define a custom run-time menu for a control and you save that run-time menu with the control, you cannot localize the run-time menu. As a workaround, you can save the custom run-time menu to an external file and point the control to that file, or you can build the run-time menu dynamically with localized strings.
[*]LabVIEW does not correctly hide subpalette menus that belong to locked project libraries.
[*]When you print the VI Hierarchy window, LabVIEW does not print the VI labels.
LabVIEW MathScript
[*]If you select File»Save for Previous Version and save a VI that contains a MathScript Node for LabVIEW 8.0, the VI is broken when you load it in LabVIEW 8.0. To correct this problem, load the VI in LabVIEW 8.0 and then modify the script in the MathScript Node. For example, add and remove a space. Then click the block diagram outside of the MathScript Node. When you click the Run button, the VI runs correctly.
[*]MathScript does not support string inputs that use LaTeX syntax.
[*]If you mass compile VIs last saved in a previous version of LabVIEW and the VIs contain MathScript Nodes, LabVIEW might return error messages, but LabVIEW compiles and saves the VIs correctly.
[*]If a LabVIEW MathScript contains a gca, get, or set function, LabVIEW ignores the function and executes the remainder of the script as normal. LabVIEW does not return errors or warnings for these functions in a script.
LabVIEW Object-Oriented Programming
[*]If you delete a control, indicator, or constant of a LabVIEW class, the backup object keeps the LabVIEW class loaded in that application instance. This backup object can cause a problem if the LabVIEW class is loaded in more than one application instance. To edit the LabVIEW class, make sure the class is loaded in only one application instance. The backup object might be the only reason the LabVIEW class stays in memory in an application instance. To remove the backup object for the LabVIEW class, save or close the VI(s). Refer to the KnowledgeBase at ni.com for more information about correcting this problem.
[*]If you rename a parent class while any child classes are in memory, LabVIEW does not record the mutation history of the class correctly. LabVIEW resets any flattened data or non-default data in memory to the default value. To avoid losing data, rename a class only when it is not in memory. Refer to the KnowledgeBase at ni.com for more information about renaming LabVIEW classes.
DataSocket
[*]If you call the DataSocket Open, DataSocket Write, and DataSocket Close functions in succession repeatedly, LabVIEW leaks memory. To correct this problem, call the DataSocket Open function once, use the DataSocket Write function to write multiple times, and then use the DataSocket Close function.
[*]If a dialog box is already open, you cannot use the DataSocket Open function.
[*]You cannot use the http protocol with the DataSocket VI and functions in LabVIEW-built shared libraries.
[*]You cannot use front panel DataSocket data binding with fixed-sized arrays.
[*]If you use the DataSocket Server Manager to create a Boolean object, the DataSocket Server Manager converts the Boolean object to numeric data in the configuration file.
Shared Variables
[*]You can read from and write to private single-process shared variables.
[*]If you open a VI that contains a shared variable from a zip file, LabVIEW displays a file dialog box indicating that it cannot find the file for the global VI associated with the shared variable. Click the Cancel button to recreate the global VI.
[*]LabVIEW fails to deploy all shared variables in a library if one shared variable has an invalid binding. To correct this problem, either delete the shared variable that has an invalid binding or unbind the shared variable.
[*]If you select File»Save for Previous Version and save a VI that contains a Shared Variable node for LabVIEW 8.0, the VI might not return correct results. If you save the VI for LabVIEW 8.0.1, the VI returns correct results. Refer to the KnowledgeBase at ni.com for more information about correcting this problem.
[*]Network-published shared variables do not function properly if multiple network adapters are enabled on the same computer.
Miscellaneous
[*]LabVIEW returns out of memory errors when you run a VI in one version of LabVIEW that calls a DLL written in C that in turn calls a DLL built in a different version of LabVIEW.
[*]If the server on which the Xmath license is installed is offline, LabVIEW hangs when you open a VI that contains an Xmath Script node.
[*]If a remote panel server is a LabVIEW development system, when a client requests a VI, LabVIEW saves an in-memory image of the VI and sends an up-to-date VI image to the client. Therefore, the remote front panel and the local VI front panel look the same. However, if a built application is a remote panel server, LabVIEW acquires the VI image from disk and sends it to the client. In this case, the VI image that the client receives might be out of sync with the in-memory image of the VI on the server computer if the client connects to a VI that has already been running. The remote front panel might not show an updated version of the VI front panel on the server computer. Refer to the KnowledgeBase at ni.com for more information about using remote panel servers with built applications.
[*]If you have more than one Ethernet card, Logos is automatically assigned to the primary Ethernet card. To assign Logos to a different Ethernet card, switch the Ethernet cards.
[*]The maximum size of datalog files is 2 GB.
[*].NET type definitions do not correctly update when you change the related assembly.
[*]If you use the Edit Items page of the Enum Properties dialog box to edit an enumerated type control that contains a large amount of items, LabVIEW 8.2.1 might perform slower than LabVIEW 8.0. To avoid this problem, use the Labeling tool to add or edit items directly from the front panel. Refer to the Adding Items to Enumerated Type Controls topic in the LabVIEW Help for more information about adding items to enumerated type controls.
Windows Vista
[*]For compatibility reasons, the LabVIEW installation process enables write permissions for the Program Files\National Instruments directory.
[*]If you have a version of PC-cillin Internet Security installed on Windows Vista, Logos does not work. Because of this issue, you cannot communicate with Ethernet instruments, such as FieldPoint modules, that use Logos.
[*]You cannot start and stop the following services from the command line on Windows Vista using the -stop parameters or the Windows net stop commands:
[*]Shared Variable Engine
[*]National Instruments PSP Server Locator
[*]NI Lookout Citadel Server 4.x
[*]Citadel 5.x Database
[*]National Instruments Time Synchronization Service
[*]National Instruments Domain Server
To start and stop these services, use the Services utility, available by selecting Start»Control Panel»Administrative Tools»Services. Also, NI applications no longer start these services automatically if the service is not running already.[*]On Windows Vista, the Enable Windows Explorer for LLB files checkbox is grayed out on the Environment page of the Options dialog box because this feature is not supported on Windows Vista.
[*]Because the default fonts on Windows Vista are different than the default fonts on previous versions of Windows, you might notice cosmetic issues, such as overlapping or truncated text strings, in VIs and LabVIEW dialog boxes. To correct this problem, change the theme of the operating system to Windows Classic in the Theme Settings dialog box and then restart LabVIEW. Select Start»Control Panel»Appearance and Personalization and click Change the theme to display the Theme Settings dialog box.
[*]You cannot install LabVIEW 8.2.1 on the Windows Vista Starter edition.
[*]LabVIEW does not support Windows Vista icons for stand-alone applications.

40L6O5VIFixed an issue where an internal error occurs when you call a VI Server property on a remote LabVIEW application, and the property then fails to get a correct value.
41KEQ3QWFixed an issue where LabVIEW does not release texture images after you use the Get Image method on an object in a 3D scene.
41422LTOFixed an issue where if you wire the count terminal of a For Loop to the count terminal of a nested For Loop, the inner For Loop might not execute the correct number of times the first time you run the VI.
43J7L3MDFixed a performance issue where when you wire a constant to the selector terminal of a Case structure, use the Case structure in a loop, and wire an input tunnel directly to an output tunnel in only one of the cases, LabVIEW might fail to use the same memory space for the input and output tunnels, which creates extra copies of the data at run time.
4474NJ00Fixed an issue where when you wire a constant to the selector terminal of a Case structure that contains a case with a negatively open-ended range in the case selector label, and the value of the constant equals the bound of the negatively open-ended range, the wrong case executes.
43Q7NJPTFixed an issue where when you wire a mixture of scalar integers and complex double-precision floating-point numbers to the Build Array function, LabVIEW generates incorrect code, which causes unexpected behavior.
4468LEU9Fixed an issue where if you wire constants to all inputs of the Format Into String function, LabVIEW decides at compile time whether to use a period or a comma as the decimal separator. If you then load the VI on an operating system with different locale settings, the Format Into String function returns unexpected results for the new settings.
447GKQTDFixed an issue where LabVIEW crashes when you use a generic probe on a matrix data type wire.
439ACNTLFixed an issue where the Remote Panel:Lock Control method and the Remote Panel:Unlock Control method do not work.

LabVIEW MathScript
406CC9TRFixed an issue where the MathScript plot window does not display correctly after you select Tools»Clear Graph to clear a graph.
3Z6CCU8WFixed an issue where LabVIEW incorrectly returns a value of not a number (power function or the carat (^) to raise a negative number to a power.
45T9T528Fixed an issue with localized versions of LabVIEW where LabVIEW crashes when reading matrix data from the MathScript Node.
LabVIEW Object-Oriented Programming
4101CU8PFixed an issue where LabVIEW crashes when you right-click a folder that contains a LabVIEW class and select Convert to Library from the shortcut menu.
40AA12CSFixed an issue where LabVIEW crashes when you rename a dynamic dispatch member VI of a LabVIEW class located in the middle of an inheritance hierarchy.
43JCLR2KFixed an issue where LabVIEW crashes when you display the Context Help window and then move the cursor over the wire of a LabVIEW class whose private data contains a VI reference that refers to a VI with a terminal of the same class type.
40O8NJMXFixed an issue where a memory leak occurs and LabVIEW might crash when you use the Build Array function to prepend a LabVIEW class object to an array.
3ZP99HN8Fixed an issue where LabVIEW hangs when you add a LabVIEW class to a library while the library is open in both the Project Explorer window and the project library window.
40667H1WFixed an issue where if you edit the cluster elements in the private data control of a LabVIEW class and you save the class but not all its member VIs, the Bundle and Unbundle functions no longer map to the correct elements of the cluster, and LabVIEW might crash.
3ZAFD6J1Fixed an issue where a LabVIEW class that is broken because of a missing VI is not fixed when you remove the missing VI from the LabVIEW class.
42B8NUJ1Fixed an issue where the LabVIEW class example Design Pattern.lvproj does not use a correct implementation of the Singleton design pattern.
4148NNJ1Fixed an issue where a custom probe that is a member VI of a LabVIEW class cannot access private or protected member VIs.
40MGGGM0Fixed an issue where if you convert a LabVIEW class into a flattened string in a stand-alone application or shared library, you cannot unflatten the class successfully in a LabVIEW development system.
3ZHCSAP2Fixed an issue where adding a static VI to a LabVIEW parent class does not immediately break VIs with the same filename in child classes. Also fixed a similar issue where removing a static VI from a parent class does not fix VIs with the same filename in child classes.
3ZBD43J1Fixed an issue where if you rename an existing dynamic dispatch VI in a LabVIEW class, LabVIEW does not allow you to rename another VI to the old name of the dynamic dispatch VI unless you unload the LabVIEW project and then reload the project from disk.
3ZP91SN8Fixed an issue where you can drag a LabVIEW class in a LabVIEW project to a target that does not support LabVIEW classes.
43DGJNFRFixed an issue where you must save LabVIEW class methods every time they load into memory even though you make no modifications to the VIs on disk.
42PC65PWFixed an issue where LabVIEW might incorrectly report that you are attempting to use some methods recursively when you try to change the inheritance of a LabVIEW class from one parent to another parent.
LabVIEW Projects
3ZPE9KUFFixed an issue where LabVIEW might return an error when you move an untitled VI between projects.

Additions to the LabVIEW Help
[*]The default behavior for the Digital Transition Location property changed to display high to low transitions at the new point on the x-axis.
[*]In LabVIEW 8.2.x, you cannot view the contents of a stand-alone application (EXE) or shared library (DLL) by renaming the application or shared library to have a .llb file extension. You also cannot access a VI in a stand-alone application or shared library by specifying the path to the VI from outside of the application or shared library.
[*]The System Requirements section on the Advanced page of the Installer Properties dialog box includes the option Windows Vista and later. Use this option if you want to specify that users have Microsoft Windows Vista or a later version to run the installer.
[*]The Create Instrument Driver Project wizard includes a progress bar so you can view the status of the instrument driver project as LabVIEW builds it. You can cancel the operation by clicking the Cancel button.
[*]The default value for the Cache VIs component of the Mass Compile dialog box changed from 5 to 10. Also, caching VIs is enabled by default.
[*]In LabVIEW 8.0 or earlier, the value for the Priority input of a Timed Loop must be a positive integer between 1 and 2,147,480,000. In LabVIEW 8.2.x, the value for the Priority input must be a positive integer between 1 and 65,535.
[*]To create a new VI or project from the LabVIEW MathScript Window, you first must return to the Getting Started window by selecting View»Getting Started Window.
[*]You must use NI Spy 2.3 or later in LabVIEW 8.x. NI Spy 2.4 is available on the National Instruments Device Drivers CD.
[*]You must use the LabVIEW Report Generation Toolkit 1.1.1 or later in LabVIEW 8.2.1. Refer to the National Instruments Web site to access the Upgrade Advisor and order the Report Generation Toolkit 1.1.1 or later.
[*]You must use Measurement Studio 8.0 or later with LabVIEW 8.2.x. Refer to the National Instruments Web site to access the Upgrade Advisor and order Measurement Studio 8.0.
[*]LabVIEW initializes a Shared Variable node the first time you run a VI that contains that node.
[*]In LabVIEW 7.x and earlier, LabVIEW enables debugging automatically for new VIs. If you then make a VI reentrant by selecting File»VI Properties, selecting Execution from the pull-down menu, and placing a checkmark in the Reentrant execution checkbox, LabVIEW automatically removes the checkmark from the Allow debugging checkbox. In LabVIEW 8.x, LabVIEW does not automatically remove the checkmark from the Allow debugging checkbox.
[*]A .NET or ActiveX property that returns a reference to a class outside the current type library cannot be made into a dotted property. When you view the property in the Class Browser window, a blue glyph does not appear next to the property name in the Properties and Methods list.
[*]LabVIEW supports smooth scrolling, or scrolling by pixels, on the front panel and block diagram of a VI.
[*]Select File»Close in a file with unsaved changes to display the Save changes before closing? dialog box. Select File»Close All to display the Save changes and Close All? dialog box.
[*]You can access LabVIEW data files from DIAdem regardless of the format in which you stored those data files.
[*]If you configure source control in LabVIEW, LabVIEW does not report an error when you save a VI to a directory outside the SCC specification.
[*]In LabVIEW 7.x and earlier, if you wire dynamic data to a waveform-based polymorphic VI that has Automatic selected in the polymorphic VI selector, LabVIEW selects the 1-channel instance. In LabVIEW 8.x, LabVIEW selects the N-channel instance. The N-channel instance returns arrays of measurement data instead of a single measurement, so VIs that use a waveform-based polymorphic VI might be broken in LabVIEW 8.x. If you want to process only the first signal in the dynamic data, you must manually select the 1-channel instance in the polymorphic VI selector.
[*]You must use an application reference when you use VI server properties and methods in one application instance, and you want to interact with a different application instance. It is not always obvious that VIs are running in different application instances. For example, each LabVIEW project has its own application instance, and each target within a project has its own application instance. LabVIEW also creates a main application instance, which contains open VIs that are not part of a project and VIs that you did not open from a project. In addition, LabVIEW opens user VIs you place in the labview\project, and labview\wizard directories in a private application instance. If you are unsure whether you are interacting with a different application instance, use an application reference.
