i want change text on txtpninscrito every time atualizador() runs don't know how this. if change text directly in button btncasa changes, want make refresher time , utilize same function refresh when doing actions on buttons.

thanks in advance. , sorry horrible english.

you need make txtpninscrito field of class it's accessible in methods within class

have @ understanding class members more details
