Application Control VIs and Functions (PDA Module)

Owning Palette: Programming VIs and Functions

Use the Application Control VIs and functions to programmatically control PDA VIs and applications.

There are some caveats to using the Application Control VIs and functions and the Menu functions in PDA VIs.

Palette ObjectDescription
Call By Reference NodeCalls the VI specified by reference. The reference VI must be a strictly typed reference.
Call ChainReturns the chain of callers from the current VI to the top-level VI.
Clear PDA ChartClears the data displayed on a graph or chart in a PDA application. The data type you wire to Tab Order of Control determines the polymorphic instance to use.
Close ReferenceCloses a refnum associated with an open VI, VI object, an open application instance, or a .NET or ActiveX object.
Configure PDA XY ScalesConfigures the minimum and maximum value of the x-scale or y-scale of a graph or chart in a PDA application. The data type you wire to Tab Order of Control determines the polymorphic instance to use.
Open Application ReferenceReturns a reference to a VI Server application running on the specified computer.
Open VI ReferenceReturns a reference to a VI, custom control, or global variable specified by a name string or path to the VI's location on disk.
PDA Get Screen SizeReturns the width and height of a PDA screen in pixels.
PDA Screen OrientationDetermines if the orientation of the screen on the PDA target changed while the PDA application was running. This VI also returns the height and width of the screen on the PDA target.
PDA Set Listbox StringsProgrammatically sets the values of a listbox control in a PDA application. The data type you wire to Tab Order of Control determines the polymorphic instance to use.
PDA Set Ring StringsProgrammatically sets the items of a ring control in a PDA application. The data type you wire to Tab Order of Control determines the polymorphic instance to use.
Property NodeGets (reads) and/or sets (writes) properties of a reference.
Quit LabVIEWStops all executing VIs and ends the current instance of LabVIEW.
Read PDA XY ScalesReads the current values of the x-scales and y-scales of a chart or graph in a PDA application. The data type you wire to Tab Order of Control determines the polymorphic instance to use.
Set Help File PathSets the file path for a Pocket PC HTML help file you create for a Pocket PC application.
Set PDA Auto Off TimeSets the time in seconds that the PDA application waits before automatically turning off the PDA device.
Show or Hide ControlShows or hides controls or indicators in a PDA application. The data type you wire to Tab Order of Control determines the polymorphic instance to use.
StopStops the VI in which it executes, just as if you clicked the Abort Execution button on the toolbar.
Zoom Chart or GraphEnables and defines zooming in graphs and charts in PDA applications. The data type you wire to Tab Order of Control determines the polymorphic instance to use.


SubpaletteDescription
Menu FunctionsUse the Menu functions to modify the menus in LabVIEW applications. Use the functions located on the top row of the palette to handle menu selections.
Palm OS Notifications VIsUse the Palm OS Notifications VIs to register and receive system-level notifications on a Palm OS device. You also can use these VIs to register and launch other PDA applications.
PDA Memory VIsUse the PDA Memory VIs to manage memory on a PDA device.
