So you should not change the pointer but rather what it points to.
Something like this maybe?

'open' : begin
restore, dialog_pickfile(),/verbose
*ptr=temporary(struc)
(*ptr)[1].bp = 0b
print,'imported values:',(*ptr).(0)
widget_control, event.top, set_uvalue=ptr
widget_control,event.top,/destroy
end
'saveas' : begin
struc=*ptr
save,struc,filename=dialog_pickfile()
(*ptr)[1].bp = 0b
widget_control, event.top, set_uvalue=ptr
widget_control,event.top,/destroy
end
