VI Properties Table

Property ID	Short Name (English)	Description	R/W	RTE
225	AutoLog.Path	Path of the datalog file in which front panel data and a time stamp are written. Note Use this property in conjunction with the Log at Finish property, which specifies whether to log the data. If you set the Log at Finish property without also setting this property, a dialog box appears at run time, prompting you to specify a file path.	R/W	X
226	AutoLog.AtFinish	Indicates whether to write front panel values to a datalog file after the VI runs. This method is similar to the Log at Completion item on the Operate menu. Note If you set Log at Finish without having set the Log File Path property, the next time this VI finishes executing, a dialog box appears prompting you to specify the file path.	R/W	X
227	AutoLog.PrintAtFinish	Indicates whether to print the front panel after the VI runs. This method is similar to the Automatically print front panel every time VI completes execution option on the Print Options page of the VI Properties dialog box and the Print at Completion item in the Operate Menu.	R/W	X
283	AutoPreallocate	Get or set the Autopreallocate arrays and strings setting on VIs. This is used by the FPGA module to optimize array and string operations by forcing LabVIEW to preallocate memory at compile time rather than dynamically allocating memory at run time. This property is similar to the Autopreallocate arrays and strings checkbox on the Execution Page of the VI Properties dialog box.	R/W	X
242	Auto Err Handling	If TRUE, enables automatic error handling for a VI. By default, LabVIEW automatically handles any error that occurs when a VI runs by suspending execution, highlighting the subVI or function where the error occurred, and displaying an error dialog box. This property is similar to the Enable automatic error handling in new VIs option on the Block Diagram page of the Options dialog box and the Enable automatic error handling option on the Execution page of the VI Properties dialog box. Note The LabVIEW Run-Time Engine does not support automatic error handling.	R/W

281	CallersPaths		R	X
2B3	Compiled.CodeComplexity	Returns the complexity of the referenced VI in relation to the Compiler optimizations slider on the Environment page of the Options dialog box. By comparing these two values, you can determine whether LabVIEW prioritizes editor responsiveness or execution speed when compiling this VI. This property provides programmatic access to the Compiled Code Complexity field on the Memory Usage page of the VI Properties dialog box. Note The value of this property is subject to change in future versions of LabVIEW. Possible Errors This property returns error 1000 if the referenced VI has never been compiled.	R	X
2B4	Compiled.LastCompiledWith	Returns the level of compiler optimizations that LabVIEW last used to compile this VI. The value corresponds to whether the complexity of the VI was greater or less than the threshold at which LabVIEW begins limiting compiler optimizations to prioritize editor responsiveness. This property provides programmatic access to the Last compiled with field on the Memory Usage page of the VI Properties dialog box. You can use this value to determine whether adjusting the complexity threshold can improve the execution speed of the referenced VI. Possible Errors This property returns error 1000 if the referenced VI has never been compiled.	R	X

2A6	Compiler.GencodeProfilingSettings		R/W
2C6	ConPane.CRC Ignore DD v2		R	X
2C5	ConPane.CRC v3		R	X
27D	ConPane.DataType	Returns the data type of the connector pane as variant data. Connector panes for VIs have a VI data type. Connector panes for polymorphic VIs have a PolyVI data type. Connector panes for custom controls, global variables, and type definitions have the data type of the control.	R	X
23E	ConPane.Ref	Returns a reference to the connector pane of the VI.	R	X
22A	ConPane.SetConPane	Sets the connector pane of the VI to match the connector pane of the VI reference input. Use this property to dynamically configure a VI connector pane to match the connector pane layout of an existing VI. The two VIs must have the same number of parameters with identical data types and names. If they do not, the Property Node returns an error. Use the Open VI Reference function to open references to both VIs and then wire those references to the Property Node and the Connector Pane:Set property input.	W
2A8	ContainsCompiledCode	Sets or returns whether the VI includes compiled code. If TRUE, the VI includes compiled code. If FALSE, LabVIEW separates the compiled code and saves it in the VI object cache. This property is similar to the Separate compiled code from source file option on the General page of the VI Properties dialog box.	R/W	X
277	HasEditsInAnotherContext		R	X

2C1	DidRecompileInThisVersion		R	X
29C	DoNotShowSaveChangesDialog		R/W
22E	Edit Mode	If TRUE, the VI opens in edit mode. If FALSE, the VI opens in run mode, and the title bar, menu bar, and toolbar do not appear. To write this property, you must call it before you open the front panel of the VI.	R/W	X
2BF	Highlight?		R/W
206	Exec.AllowDebug	If TRUE, you can use debugging tools on the VI. For example, you can set breakpoints, create probes, enable execution highlighting, and single-step through execution. Set this property to FALSE to disable use of debugging tools, reduce memory requirements, and to improve performance slightly for the VI. This property is similar to the Allow debugging option on the Execution page of the VI Properties dialog box. Note Writing this property causes the VI to be recompiled. Writing TRUE causes extra code and data to be generated for the VI. This code and data enables LabVIEW to set breakpoints and single-step through the VI. Writing FALSE removes this code and data, reducing the total size of the VI. When you debug applications and shared libraries, you cannot debug reentrant panels that an Open VI Reference function creates. You also cannot debug reentrant panels that are entry points to LabVIEW-built shared libraries.	R/W	X

29F	FP.NativeWindow		R	X
22C	FP.PanelBounds	The four elements in the cluster are the top, left, bottom, and right values of the interior portion of the front panel, not including the scroll bars, title bar, menu bar, and toolbar. The cluster elements are in global screen coordinates, which are the numbers that refer to coordinates within a computer monitor's screen (rather than an open window). You can set this property only for VIs with open front panels. If you do not want the VI for which you want to set this property to appear to users, use the Hidden state of the Front Panel Window:State property to hide the front panel of the VI. When you read this property, LabVIEW returns the front panel bounds of the VI. If the front panel of the VI is not open, LabVIEW returns the front panel bounds of the VI in the position it was last saved. The front panel bounds adjust if you change the size or placement of objects in the front panel. Dynamic changes in data can occur if you alter bound front panel objects. If you load the VI in a subpanel control, this property is read only. Elements: Name Description Left - The horizontal coordinate of the left edge of the interior portion of the front panel in global screen coordinates. Top - The vertical coordinate of the top edge of the interior portion of the front panel in global screen coordinates.

You must stop the VI on the block diagram for the front panel of the VI to become visible. You must set the Front Panel Window:Run VI Transparently property to TRUE for this property to have any effect. The default value for the Front Panel Window:Run VI Transparently property is FALSE, in which changing this property has no effect. This property is similar to the Window Runs Transparently option in the Customize Window Appearance dialog box.	R/W	X
218	FP.WinBounds	The four elements in the cluster are the top, left, bottom, and right values of the front panel window, which includes the interior region, scroll bars, title bar, menu bar, and toolbar. They are in global screen coordinates, that is, the numbers refer to coordinates within a computer monitor's screen (rather than an open window). You can set this property only for VIs with open front panels. If you do not want the VI for which you want to set this property to appear to users, use the Hidden state of the Front Panel Window:State Property to hide the front panel of the VI. When you read this property, LabVIEW returns the window bounds of the VI. If the front panel of the VI is not open, LabVIEW returns the window bounds of the VI in the position it was last saved.

2B0	TermBnds()	Returns an array of terminal bounds for the connector pane of the referenced VI. The bounds for each terminal are represented as a cluster of integers that indicate the position of each edge of the terminal rectangle. This property provides a more efficient way to obtain the terminal bounds of a connector pane than the similar Connector Pane:Terminal Bounds[] property. The Connector Pane:Terminal Bounds[] property causes slower run-time performance because it requires LabVIEW to load and maintain the front panel of the associated VI in memory, even if you close the connector pane reference with the Close Reference function. The VI:Terminal Bounds[] property does not load the front panel of the associated VI into memory. Use this property to avoid the negative run-time performance impact of the Connector Pane:Terminal Bounds[] property, such as when you need to inspect the terminal bounds of a connector pane from a custom plug-in for the Icon Editor. The array elements are in terminal order as defined in the Connector Pane Pattern Reference VI for each connector pane pattern.	R	X

41C	Ctrl Val.Get	Gets the value of a named control or indicator as variant data. Use the Variant to Data function to convert the data to another LabVIEW data type. Note This method requires the VI to have a front panel. If you are using the Application Builder, make sure you do not remove the front panel. For optimization purposes, LabVIEW does not keep track of data values on controls and indicators until LabVIEW determines you want them, that is, until you call this method or display the front panel. When you display the front panel, LabVIEW begins keeping track of the values. The first time you call this method on a VI whose front panel is not open, this method returns the default values of the control or indicator rather than the actual values. Thereafter, it returns the actual value.	X
41D	Ctrl Val.Get All	Gets the values of all controls or indicators in a VI as variant data. This method returns an array of clusters that contains control and indicator names and their values as variant data. Use the Variant to Data function to convert the data to another LabVIEW data type. Note This method requires the VI to have a front panel. If you are using the Application Builder, make sure you do not remove the front panel.

If you are using the Application Builder, make sure you do not remove the front panel.	X
4A1	Ctrl Val.Set Multiple		X
485	Copy VI Hierarchy FPGA
49D	Create from Data Type	Creates a control or constant of the data type you specify. LabVIEW always creates a control initially, even if you configure Style to create a constant or indicator. To change the type of the new object, use the Indicator property. Use the To More Specific Class function to try to cast the reference this method returns to the specific class you want to use in the application. If the function does not return an error, the reference matches the specific class.
443	Create from Reference	Creates a constant or control using a constant or control reference as a template.
484	Debugging:GetButtonState	Returns TRUE if the button is enabled or FALSE if the button is grayed out. This method also returns the string for the tip strip associated with the button. For example, this method might return Step into For Loop for the Step Into button.	X

425	FP.Close	Closes the front panel window. Use the Front Panel:Open method to open a front panel window. Example	X
423	FP.Get Image	Returns an image of the front panel as a flattened pixmap. Use the Front Panel:Get Image Scaled method to return an image of the front panel and scale it proportionally according to the maximum width and height you wire to the method. If a front panel is not visible, LabVIEW does not update the values in the objects on the front panel. If you call a VI whose front panel is not visible and you use the Front Panel:Get Image method to create an image of the front panel, the image does not reflect any value changes that occurred when you ran the VI. If you want the image to reflect value changes, make sure the front panel is open before any values change. If you do not want to display the front panel but want the image to reflect value changes, create a Property Node from any terminal on the block diagram of the VI for which you want to create a front panel image. You also can use the Append Front Panel Image to Report VI to create an image of a front panel and append it to a report.	X
426	FP.Get Image Scaled	Returns an image of the front panel and scales it proportionally according to the maximum width and height you wire to the method. This method is similar to the Front Panel:Get Image method. If a front panel is not visible, LabVIEW does not update the values in the objects on the front panel. If you call a VI whose front panel is not visible and you use the Front Panel:Get Image Scaled method to create an image of the front panel, the image does not reflect any value changes that occurred when you ran the VI. If you want the image to reflect value changes, make sure the front panel is open before any values change. If you do not want to display the front panel but want the image to reflect value changes, wire a Property Node to any terminal on the block diagram of the VI for which you want to create a front panel image. You also can use the Append Front Panel Image to Report VI to create an image of a front panel and append it to a report.	X
438	FP.Open	Opens the front panel window. If the front panel is already open, this method changes the state of the front panel window to the state you wire to this method. Use the Front Panel:Close method to close the front panel window. You also can use the Front Panel Window:State property to set the state of a front panel window that is already open. Example	X
477	FP.OpenInNativeWind		X
447	FP.Run-Time Position.Centered	Configures the referenced VI to center its front panel every time the VI runs. If the VI is running when you call this method, the change does not take effect until the next time the VI runs. If you want to change the position of the VI while it is running, use the Front Panel Window:Window Bounds property instead. This method is similar to selecting Centered from the Position pull-down menu on the Window Run-Time Position page of the VI Properties dialog box.	X
44A	FP.Run-Time Position.Custom	Configures the referenced VI to open its front panel in a custom position every time the VI runs. If the VI is running when you call this method, the change does not take effect until the next time the VI runs. If you want to change the position of the VI while it is running, use the Front Panel Window:Window Bounds property instead. This method is similar to selecting Custom from the Position pull-down menu on the Window Run-Time Position page of the VI Properties dialog box.	X
445	FP.Run-Time Pos.Get	Returns the default position of the front panel window at run-time.	X
448	FP.Run-Time Position.Maximized	Configures a VI to maximize its front panel every time the VI runs. If the VI is running when you call this method, the change does not take effect until the next time the VI runs. If you want to change the position of the VI while it is running, use the Front Panel Window:Window Bounds property instead. This method is similar to selecting Maximized from the Position pull-down menu on the Window Run-Time Position page of the VI Properties dialog box.	X
449	FP.Run-Time Position.Minimized	Sets a VI to minimize its front panel every time the VI runs. If the VI is running when you call this method, the change does not take effect until the next time the VI runs.

49E	GetCallPathsToOtherVI		X
495	GetCompileMetrics	Returns a string that describes transform metrics from the most recent compile of the VI, if metric recording was enabled.	X
42D	Get Conpane Image	Returns the connector pane image, as it appears in the Context Help window, as a cluster of image data so you can draw it as a picture using the Draw Flattened Pixmap VI or save the image to a file using the Graphics Formats VIs. The clusters returned by this method are similar to the image data output of the Read JPEG File, Read PNG File, and Read BMP File VIs.	X
4A7	GetControlIndexByName	Gets the index for the control or indicator of the given name. If the control or indicator for which you want to get an index does not have a terminal on the block diagram, this method returns an error. You can use this method to specify the controls for which you get or set values with the Get Control Values by Index or Set Control Values by Index functions.	X
452	Get Errors		X
49B	Get Library Access Scope	Returns the access scope or inherited access scope of this VI if it is owned by a LabVIEW project library. This method provides the same information as the method Source Scope:Get of the Project Library class without requiring a reference to the owning project library.
461	GetMenuItemState (Not Implemented)		X
4AC	GetMissingDependenciesInfo		X
46C	GetNamedInstanceVI		X
4A9	GetObjRefFromBkmrkID	Returns a reference to the object, such as the label, that contains the bookmark.	X
4AF	GetUDClassLinkRefs
4A8	GetVIBookmarks	Returns the bookmark information for the specified VI reference. You must load the VI into memory in order to read the bookmark information. This method returns an error if the VI is password protected or if the VI does not have a block diagram.	X
47A	Get VI Dependencies	This method returns the names and paths of the VI dependencies of a VI. You can use this method to return a specific subset of the total set of VI dependencies of a VI. This method does not return non-VI dependencies, such as project libraries, XControls, classes, and statecharts. LabVIEW combines the parameter values you specify using the logical AND operator to determine which dependencies to return. For example, you must pass TRUE to both Static VI Refs? and Include Control VIs? in order for LabVIEW to return a static VI reference to a custom control or indicator. By default, this method does not load the block diagram into memory. However, if you specify certain input values, LabVIEW loads the block diagram.	X

494	License.Get License Status		X
3FD	Lock State.Get	Returns the lock state of the VI and indicates whether the password for the VI is in the password cache.	X
3FE	Lock State.Set	Sets the lock state of a VI. If interactive is FALSE (default), you can use password to either unlock a password-protected VI or set the password of an unprotected VI. If interactive is TRUE, LabVIEW ignores password and displays a dialog box that prompts you to change the lock state. This method is similar to the Unlocked (no password), Locked (no password), and Password-protected options on the Protection page of the VI Properties dialog box.
460	MoveObjects	Moves the objects by the offset amount of pixels.
480	PauseVI	Pauses or unpauses the VI execution.
4A2	Populate Async Call Pool	Ensures that the asynchronous call pool for a VI reference contains at least the number of data spaces specified by the Minimum Size parameter. By default, when you open a reference with the Open VI Reference function, LabVIEW allocates one data space per CPU core on the development computer. Use this method to ensure deterministic execution of asynchronous VI calls. Set the Minimum Size of the call pool to the maximum number of calls that you expect to make to the referenced VI. This prevents LabVIEW from needing to allocate data spaces in the asynchronous call pool on demand, thereby avoiding the jitter of memory allocation.	X
415	Print.Panel To PostScript	Prints the panel of the VI to the specified PostScript file.	X
3FB	Print.Panel To Printer	Prints just the front panel to the current printer. You cannot use this method to print a block diagram, list of controls, or polymorphic VI front panel.	X
3EE	Print.VI To HTML	Saves the VI information to an HTML file and saves the graphics in external files. You can use the Open URL in Default Browser VI to display the HTML file in the default Web browser. This method is similar to the HTML file option on the Destination page of the Print dialog box.
3ED	Print.VI To Printer	Prints the VI information to a printer. If you use this method in a stand-alone application or shared library, LabVIEW prints only the front panel. This method is similar to the Printer option on the Destination page of the Print dialog box.	X
3EF	Print.VI To RTF	Saves the VI information to an RTF file. This method is similar to the Rich Text Format (RTF) file option on the Destination page of the Print dialog box.
3F0	Print.VI To Text	Saves the VI information to a text file. You cannot save the icon, connector pane, front panel, block diagram, subVI icons, and VI hierarchy to text. This method is similar to the Plain text file option on the Destination page of the Print dialog box.
473	RefreshErrWinEntry		X
430	RP.Client Connections	Returns an array of clusters containing connection information about the clients viewing or controlling the VI. LabVIEW opens a connection on the server computer when another application instance or a related application, such as a Web browser, requests to view the front panel of a VI in memory on the server computer. This method can return networking error codes. Example	X
431	RP.Close Connection To Client	Closes a remote front panel connection to a client. This method can return networking error codes. Example	X
42E	RP.Lock Control	Returns control of the front panel to the server and queues any requests from clients to control the front panel. LabVIEW ignores this method if the front panel is already locked. This method is similar to the Regain Control and Lock Control shortcut menu items on the front panel of a running VI. Example	X
42F	RP.Unlock Control	If the front panel is locked, this method grants control to the next client in the queue. If no clients are in the queue, the method unlocks the front panel. LabVIEW ignores this method if the front panel is already unlocked. This method is similar to the Unlock Control shortcut menu item on the front panel of a running VI. Example	X
44F	RemoveBreakpoints		X
44D	Replicate Conpane	Make the connector pane of the VI Reference match the given connector pane.	X
492	ResetGencodeProfileResults
3FA	Revert VI	Discards changes and reloads a VI from disk. This method is similar to the Revert item on the File menu.
3EB	Run VI	Starts the VI execution, similar to the Run button. This method is different than calling a VI because it uses the current values of all front panel controls for execution rather than using data passed in through parameters. This method also ignores the Execution:Show Front Panel On Call property of a VI and the Execution:Close After Call property. Note This method requires the VI to have a front panel. If you are using the Application Builder, make sure you do not remove the front panel. You cannot use this method to run a VI that is already reserved for execution by another VI. If you use the Open VI Reference function and wire the type specifier VI Refnum input, you cannot use the reference returned by the function with this method. Instead, you must use the Call By Reference node. If you want to use this method with a reentrant VI, set the options parameter to 0x08 in the Open VI Reference function to prepare the VI for reentrant run.	X
467	Run VI And Deploy		X
45A	Save.CopyAsSystem		X
400	Save.For Previous	Saves a copy of the VI that is readable by LabVIEW version 8.0 and later. If you save a password-protected VI for a previous LabVIEW version, you must enter the password. You can enter the password programmatically as an input on the Open VI Reference function. This method is similar to the LabVIEW Version option on the Save for Previous Version dialog box.
3EA	Save.Instrument	Saves a VI that is not currently running and synchronizes the VI with the edited version in other application instances before saving. This method is similar to the Save item on the File menu. Note If you use this method to save a VI that is currently running, LabVIEW returns error 1507.

421	VI Icon.Get as Image Data	Returns the VI icon as a cluster of image data so you can draw it as a picture using the Draw Flattened Pixmap VI or save the image to a file using the Graphics Formats VIs. You also can use the VI Icon:Save to File method to save an image of the VI icon to a file. The clusters returned by this method are similar to the image data output of the Read JPEG File, Read PNG File, and Read BMP File VIs.	X
4A3	LoadVIIconManually
418	VI Icon.Save to File	Saves an image of the VI icon to a file. You also can use the VI Icon:Get As Image Data method to return the VI icon as a cluster of image data.
407	VI Icon.Set from File	Sets the image of a VI icon from a file. LabVIEW creates a user layer called VI Icon for the image and deletes any other existing icon information from the Icon Editor dialog box. You also can use the VI Icon:Set from Image Data method to set a VI icon from image data you specify.
422	VI Icon.Set from Image Data	Sets a VI icon from image data you specify. LabVIEW creates a user layer called VI Icon for the image and deletes any other existing icon information from the Icon Editor dialog box. If you want to use a pixmap to set the icon, use the Flatten Pixmap VI to convert the data to an image data cluster before using this method. If you want to use a picture to set the icon, use the Picture to Pixmap VI to convert the data to an image data cluster before using this method. Use the Create Mask VI to make a certain color in the image data transparent before wiring the image data to this method.
3E8	VI Strings.Export	Exports the following strings about VI and front panel objects to a tagged text file: VI name and description, object caption labels, object free labels, default data (string, table, path, and array default data), private data (listbox item names, table row and column headers, graph plot names, graph cursor names, graph annotation names, and tab control page captions), and polymorphic VI data (instance names in the polymorphic VI and selector shortcut menus). This method is similar to the Advanced»Export Strings item on the Tools menu.
42B	VI Strings.Export Private
