Sending ON_UPDATE_COMMAND_UI to child windows

MDI Child gets a ON_UPDATE_COMMAND_UI for ID_EDIT_COPY then forwards it to the child window of the MDI Child with the focus.

This must be done for each indivitual UI object? Or is there a way to just send all the ON_UPDATE_COMMAND_UIs to the child window that has the focus?

It seems redundant (and time consuming) to have to forward every ON_UPDATE_COMMAND_UI to the active child window.

"Windows-based programming is strange. It's weird, it's warped, it's awkward, it's convoluted, it's mind-boggling. It's definitely not immediately obvious, and it may take some time before you experience the thrill of shouting "Eureka!" - Charles Petzold, highly aclaimed author of windows books.
