Can I open a VI using another VI
There are 2 ways to do this.
1) When creating the VI that will be the sub-VI, from the menu bar,
choose FILE, VI Properties. Then use the drop down menu to choose
Window Appearance, and press Customize. Now click on Show Front Panel
When Called and Close Afterward if Originally Closed. Now this VI will
"Open" every time that it is called.
2) Place the sub VI icon on your diagram and right click on it. Now
choose Sub VI Node Setup. Click on Show Front Panel When Called and
Close Afterward if Originally Closed. This works for THIS instance of
Hope this helps.
