Pick File/Pick Directory "cancel" button

[#1]

Hi all,

I use Pick File Function and Pick Directory Function in my script. In the pop up window, how could I "stop" the script if I click the "cancel". I know how to stop the script using the cancel button:

Button Box( "Cancel", stop_flag = 1 )

but this doesn't work for the pop up pick file/pick directory window...

Any help would be really appreciated!

Just check on the returned value

names default to here(1);

xx=pickfile();

if( xx == "", stop() );
