I want to be able to show (or hide) the Front Panel of a Sub VI at a certain moment during the execution of the Sub VI. The Sub VI will normally execute without showing the Front Panel but in the middle of it's execution, I would like to be able to show the Front Panel to the User if required. I know it can be done easily in LabView 7 using the "Open FP" and "CloseFP" Methods but I am using LabView 6. Thanks.
