I don't know how to do what your asking.. but try this.

In the parent and child do:
hAtomTbl = WinQuerySystemAtomTable();
WM_Your_atom = WinAddAtom(hAtomTbl,"SOMENAMEYOUCHOOSE");

Have the child when able do a broadcast message that only the parent would know.

WinBroadcastMsg(hWnd,WM_Your_atom,MPFROMHWND(hWndChildFrame),0L,BMSG_POSTQUEUE);

And in the parent be ready to recieve the message, in this example mp1 would
contain the window handle. Once you have this a more private comunication
can take place.
