controlling on exit

[Eyecheck2003]

I am developing an application where I have put exit under the file menu. When somebody wants to exit, I then ask if they want to save their data.

People also want to be able to close the program with the normal windows exit box in the upper RH corner. Is there a way that if they click the X (I currently have disabled), that I can then prompt to see if they want to save data first?

Thank you.

Use a filter event (This VI..Panel Close?) and wire the outcome of your confirmation dialog to the "discard" terminal. (See attached example).

With LV 7 (and probably 6.1), you can use an event structure to capture and
control the Panel Close? or Application Exit? events. You can discard the
default handling and write your own.

I don't think its possible to do it in 6.1, I've used 6.0 and you cant easily. But you could catch the window messages and parse the
messages before the application exits.
look for windows message queue library on the NI site.

Cheers

See the previous post from Altenbach. It can be done in LabVIEW 6.1 with
the event structure. The event structure is a new feature in LabVIEW 6.1.
