Hello,
Ive got a quite big program, with a lot of sub-VI, which are opening
windows. I would like now to use a "Tab Control" tool, in order to
integrate all this sub-VI in my main VI (user wont see anymore
windows opening, but he will navigate through the pages of the Tab
Control). The problem is that Ive got more and more a gigantic
Diagram (containing all variables references linked to sub-VIs).
Thats  why Im looking for methods able to solve this problem. I have
also got the fear that my program will become more slowly, thats why
Im using shift registers that allow the program to realise operations
only when a modification has been done. But It takes also a lot of
place on my diagram.
The question is : could I define on the main-VI, a selection where a
subVI-panel could appear, and that would not necessite the use of
local variables in my main VI.

I would like to thanks you for your help,
    With regards,

    Nicolas Minary

Not yet... But as the question again this summer and you might get a
different answer.Mike...

With LabVIEW 6.1 and below you cannot select a position of a front
panel to have a SubVI appear.  You can however use property nodes to
dictate weither the SubVIs front panel opens, and specify the location
where the panel opens.  It will not be contained within the main VIs
front panel.
