Closing child panels

[Clueless1]

Hi,

I'm opening by reference some vis to use as dialogs and to do various tasks in my application.  When I close the main panel, what is the best way to close the children  panels.  I'm  using an events structure for closing and minimizing the child panels now by writing to the properties of the panel references..  Do I just close the references using the vi-panel-close event?

Thanks

you mean the panel close node. yep! but first close front panel, and then close reference.

What I meant is wait for an event in the parent vi.  The one called vi/panel close. 

So, from what I gather what i want to do is, using the property node of the children's vi reference, close the panel.  Then close the reference itself. Yes?

Thanks

Yes.

Failing to close the panel before closing the reference will give you  a  stopped VI with open front panel.

A VI stays in memory when either a reference to the VI is open or its front panel.

generally i always do a check at cloe of main application, if there is any panel open from the vis called by reference. the reference is then used to close the panel, and only then release the reference.

if you close the reference without closing the panel, and the vi is set to reentrant, you will have trouble to close the panel, especially if there is no menu or title bar on this panel (or it is disabled).

I have a couple of more questions


Is there an easy way to get all of the references of all of the vi's called by reference (including grand children etc.) and is there a way to figure out if a VI is an exe, or is running in the development system?

The child can handle it in the timeout case, check callers state using call chain.  If callers (parent) state stops executing then goto the exit state of the child routine.

To answer your question about running in the development environment vs. as an executable, see the following KnowledgeBase on Determining if an Application is Running as a VI or an EXE.
