how to get data outside a while-loop into another vi

[joop]

Hi there,
when i'm in a while-loop i want a progressbar, which is inside the loop, be available outside the loop and in another vi. I tried local variables and shift-registers but nothing works. The value is only transferred afterwards, when the while-loop stops.

best regards,

Hi Joop Tap,


THe simplest solution to your question is a "global variable".

First copy your progress bar indicator into your clip-board and then go to your diagram.

On the structures palette there is a structure called a global. Drop one on your diagram and double click on it to open its front panel. Now drop your progress bar you copied earlier. save and close the global. On your original diagram your should be able to right click on the global and select your progress bar. Wire it next to your existing progress bar.

This global can be copied into another VI and read from there whenever you need.

This is just one way of sharing information between part of programs. Other methods inculde "Functional Globals" Queues, and notifiers.
