How do I avoid flicker in maximize or minimize the form

how do you resize your Form and Controls ?

if it's flickering, it could be because of too much 'redraw' .

while( resizing ){ refresh_controls() ;  ) // too expensive , bad process , high cost of actions

// take it easy

while( resizing ) { // no action on controls ; }
wait_for_stop_of_border_moving(){ resize_controls() };

change your 'events' firing 'maximize/minimize'. fire their functions one time only, not between two size of your Form.

I imangine when you grab a border to resize, the function resize go on and on and on. give up with it.

use your resize function only when the border resize stop.
