I am trying to create a MDI like UI for my app. One thing I can't seem
to duplicate to my liking is how the child windows in a MDI app show
the title bar as active when it is active. Snooping with WinSpector
Spy I see, as I expected, that I don't get WM_ACTIVATE or WM_NCACTIVATE
when the child window is activated (gets the focus). I snooped on a
MDI application and see that the window that shows the child windows
are getting WM_ACTIVATE and WM_NCACTIVATE messages.
The Styles and Extended Styles are the same as the MDI app (other than
the WS_EX_MDICHILD of course). How does the MDI manager make children
of the Client window look like Top Level Windows and send WM_ACTIVATE
and WM_NCACTIVATE messages?
Thanks,
Jim

Never mind, figured it out. Just send the WM_NCACTIVATE message myself.

MDI uses WM_MDIACTIVATE message to activate its children. Probably
the default handler (i.e. DefMDIChildProc) calls SetActiveWindow.

Tried that with out any luck. SetActiveWindow is documented to work
for Top Level Windows.
