Loading a second form clearly from first form without any blinking ???

Hi all,

i am successfully able to move from one ui1 from to another ui2 form & vice-verse through button click.But the issue is while moving/loading second form
i am not able load the second form clearly...means it showing some kind of blinking while moving to second form....how to load second form cleanly without any
kind of blinking by closing first form ???

i tried the following steps-------(button click event)
1) first showing form2 (form2.show)
then closing or hiding form1 (form1.close or form1.hide)

2) first closing or hiding form1 (form1.close or form1.hide)
then showing form2 (form2.show)
