Why can I close the parent VI when the child is modal?

[twols]

When calling a modal dialog in the main VI, I can almost always close its parent using the task bar (right click and close). The parent disappears but the modal child still there.

 

 

It is not the purpose of a modal window. As far as I know, systems native modal diologs prevent any interaction with their caller.

 

Can I "protect" the main window from beeing closed when the modal dialog is shown? Or close the modal dialog too?

 

LV 2012

Dialog.vi

Main.vi

 

I'm using Windows 7.

I don't know. I gave Main.vi something to do, though, and now both VIs stop when closing from the start bar.
