WM_GETMINMAXINFO is intended for top-level windows, or
windows with sizeable borders (ie. popup windows).  It is
used when a window is sized via the system menu, or via the
sizing borders.

You did not say what type of window you want to control, but
in general, you can use the WM_NCCALCSIZE message to control
the final size.  For example, ListBoxes use this message to
ensure that the height of a list is an integral number of
entries.
