Insert VI
Loads a VI in the subpanel control without changing the state of the VI.
If the front panel of the VI you want to load is open or if you loaded the front panel in another subpanel control on the same front panel, LabVIEW returns an error, and you cannot load the front panel in the subpanel control unless the front panel is reentrant. You also cannot load the front panel of a VI in a remote application instance, and you cannot load front panels recursively.
LabVIEW also returns an error if you wire a custom control to this method. To wire a custom control to a subpanel, place the control on the front panel of a VI. Then wire that VI to the subpanel.
After you use this method, the front panel is in memory. Use the Close Reference function to close the VI reference. The front panel remains in the subpanel control until you stop the VI that contains the subpanel control. You also can use the Remove VI method to unload the VI in the subpanel control.
