BridgeVIEW System Control
As you develop more sophisticated user interfaces, you might find that you
need to exercise control over portions of the BridgeVIEW environment
from your own applications. The System VIs palette provides mechanisms
to programmatically control the BridgeVIEW Engine.
System VIs
The System VIs provide you with several functions that control actions
such as launching and shutting down the Engine, enabling and disabling
logging, invoking the Login dialog box, and so on. You can reach the
System VIs through the Functions»System VIs palette, shown below.
For more information about the System VIs, refer to Appendix A,
