how to scale the controls whenever the form resizes!

You have the answer then.

these are the things that i want: whenever the form resizes, all the controls inside the form will resize in proportion of the forms width and height.

More information please.... Please don't assume that we can read your mind!!! Generically you can use the controls anchor and dock properties. The anchor keeps the distance of the control side equal to the parent control (in your case the form) the same. By default anchor is set to top and left. Dock anchors the control side to the side of the parent control.
