I'm using VS 6.0 with MFC and have a dialog that can be resized.
I want to set the Client area size to multiples of 253 pixels in the X direction.
Example: If the user drags the size to be 520 pixels wide and lets go of the mouse button, the program should force a client area of 506 pixels.
As I'm using MFC I'm not sure where I need to call SetWindowsPos()
Is it in the OnSize() ?
