That is not the problem the MDI classes deal with this automatically.

Unfortunately I only know the raw Windows API not the MFC extension of this but I am sure someone using MFC a lot will know.

The basics are there is an invisible transparent client area in an MDI class and it is that which is responsible for all the default message behaviour including moving the min/max icons to the frame of the parent window. The MDI child window is supposed to call DefMDIChildProc rather than DefWindowProc as it's default message handler.

If you look at a sample when for example I run OpenGL sessions in each MDI the redraws are automatically dealt with.
Native Win32 API OpenGL Tutorial - Part 2[^]

The MFC base class needs to setup the MDIClientArea and change the handlers of the children and that is all that is missing. The process and setup MFC needs to do that is all you need to know and I am sure someone will tell him.

He told you the min/max icons aren't moving to the parent properly so it is definitely the message handler nothing to do with the paint.
