RE: Dialog activation issue (hard problem?)

Found this article:http://chabster.blogspot.com/2010/03/focus-and-window-activation-in-win32.html
It seems I need to handle WM_ACTIVATE? i.e.,  on receving one the messages, instead of passing the control to
default dialog procedure, I need to call SetFocus on the GUI widget that was clicked?
Thanks,
Dennis

but they do not live on same levels.

SetCapture for mouse and SetFocus for keyboard on mouse move or mouse enter event. I do this both for the
embedded dialogs and for the 3D canvas window. That is,when mouse enters the embedded dialogs,
SetCapture and SetFocus is called to set focus/capture to the dialog where mouse cursor is. When the mouse
is moved back into the 3D canvas, I do the same. This introduce another annoyance: when the mouse cursor is
moved back to 3D canvas, any floating non-modal dialog will NOT get focus, unless the mouse cursor is set to
a hot-tracking widget (e.g. a button that reacts to mouse enter event) in the non-modal dialog. This means
I have to make all controls in the non-modal dialog track with
  the mouse movement. But as the application must run as an ActiveX control in another host, I have no controls
to any non-modal dialog displayed by the 3rd party host.
