I'm using MFC and I have a multi view document with wizard generated child frames and docs and views. When a child frame appears, I would, when the user clicks on any of the sides of the window to try to resize the window, increase or decrease the x and y positions evenly. I would like the child frame to remain a square, and if the user tries to resize one side, have it remain a square and not turn into a rectangle. Does solving this have something to do with handling the ON_WM_SIZE message that is sent?
Thank you.
