MDI app: passing data from Main frame to child frame

[p***@yahoo.com]

Hi all, I am creating a MDI app using MS VC++ and I want the children to share some common data. How can I pass these from the main frame (mainfrm.cpp) to the child windows (childfrm.cpp)?
TIA
Phil

You can iterate through all document templates, all documents and all views using GetFirstDocumentTemplatePosition, GetFirstDocPosition, GetFirstViewPosition and related functions.

in your children....

auto pMain = DYNAMIC_DOWNCAST(CMainFrame, AfxGetMainWnd()) ;
ENSURE(pMain);
auto data& = pMain-> call some function to access data;
