In my application i am using several Write Characters to File, and Read
Characters to file. The app is a GUI that allows a user to create
simple "configuration files". I want the user to be able to
open/close/create new files, as the application is running, similar to
what you would find in any Windows based program, under the "File"
menu, but maybe with just some simple Boolean buttons for "Open" "Save"
and "New".
At the moment i have a Open/Create/Replace File.vi outside the While
loop, which links the path into all the Write/Read characters to file.
With this configuration, the user gets a file dialog everytime the app
starts.
I have tried several different methods (open/close/create new file
inside case structure etc), but all culminating in the fact that Write
Characters to File produces a dialog if no path is present.
The ideal solution for me, would be to have a simple FILE PATH CONTROL
on the front panel, that allows the user to switch file/create new,
anytime while the application is running.
Is there an elegant and simple way to do this?
Cheers
