Disable State PolyVI

Grayed if Empty String

Set disabled output to "grayed" if input string is empty.

Coerce to Enabled Item

Check if Start Item is among Disabled Items, and if so, select an enabled item instead. Disabled Items must be sorted in increasing order. Generic Error results if all items up to Last Item are disabled. Search for an enabled item will preferentially select a smaller item number.

Print Image

Prints the specified image by drawing the image to the front panel's picture control and then printing the panel.

Exit if Runtime

Check if runtime system and exit the application if it is. Useful for development vs. runtime exit conditions. The "Data Dependency" input is provided to prevent this VI from executing until data has arrived from upstream. Also closes the front panel of an executable before exiting LabVIEW, eliminating annoying flicker as front panel moves into the non-running state.

Get File Version

If this VI is built into an executable, it returns the file version (different than the product version) of the executable. When run in the development environment it simply returns "Development". Executables created with versions of LabVIEW earlier than 8.0 do not include the necessary information in the executable for this VI to return the version.

Is Runtime

The VI returns a boolean indicating whether it is being run in an executable or in the development environment.

Set Listbox Scrollbar

This VI adds the vertical scrollbar to a listbox if there are items that are not visible and removes it if there are not.

Set Slider Text Markers

Set the specified Slider to use the specified Text labels at the specified Y Values.

MGI_VI Property Node

Merge VI for dropping a property node with VI type already selected.
