Child's DoDataExchange is never called in child dialog ? - MFC

Question

I simply want to open a child dialog and have it print a result from the parent dialog in one of the child's static text controls. Using breakpoints I noticed that both DoDataExchange and my overloaded OnInitDialog are never called in the child so the static text control crashes any time i try to print something to it. The child dialog does display itself fine otherwise.

What could be the problem ?

//in parent.cpp
CResultsDlg childResultsDlg = this;
childResultsDlg.DoModal(15.7); //overloaded to pass value to a child member var

All of the basics of MFC are covered in the SCRIBBLE tutorial.

An example of passing data into a dialog and displaying that data in dialog controls is provided in the tutorial with the CPenWidthsDlg.
