QUOTE(tcplomp @ Sep 24 2007, 12:12 PM) Hi Ton Thanks for your help.What I'm going to do is to pass this refum of the string to a reentrant subvi,and make this subvi run in background,which would always change this string control'state,such as change the color every 1s(blinking).So the string control would always change its color no matter in run model or edit model .And at the end I would terminate the subvi in uninit.vi. This idea comes from a blog of someone,but without the detail. Is this possible?Or would you have an other method? Jack

I have a string control on the facade.vi,and now I want to use this string control by it's refum(in init.vi).Is there anybody can help me? Thanks. Jack.
