Part 2: Automation Programming Reference
Application Interactions
It is not possible to run two simultaneous instances of the oscilloscope application. More than one
simultaneous connection to the instrument via Automation will be accepted, but simultaneous
connections are not recommended. When the final client has been disconnected from the instrument
(server), the oscilloscope application will remain running and will accept further client connections.
Operations that cause Modal Dialogs to appear in the instrument’s display will, by default, disrupt access
from Automation. This behavior can be changed using the controls:
l app.SystemControl.ModalDialogTimeout
l app.SystemControl.EnableMessageBox
The instrument application can be minimized in order to allow the controlling application to take over the
display and touch panel by means of the app.Minimize control. It can also be resized and repositioned on
the display by means of the app.Top, app.Left, app.Bottom, and app.Right controls.
When an application is running locally on the instrument and requests a connection to the oscilloscope via
Automation, one of two things will happen:
l If the oscilloscope application is already running, the object returned will be a “pointer” to the
running application.
l If the oscilloscope application is not running, it will be started.
