i think my prob. with this is that i dont want my subVI to close unless i specify them. i will post my program tomorrow thanks.
I actually need a button in my mainVI to reset mainVI front panel settings and close subVIs (that is opened). And this button is suppose to be able to work anytime. Thus the prob. arise when my subVI is not opened and "close FP method" cannot work. Any better ideas to make such buttons could be helpful.
