move variable field or property in form class. here example code:

public class form1     private myvariable      private sub form1_load(sender system.object, e system.eventargs) handles mybase.load         myvariable = "hello"     end sub      private sub button1_click(sender system.object, e system.eventargs) handles button1.click         messagebox.show(myvariable)     end sub end class
