Both your answers make sense. Actually I've never caught a message in my CDocument classes .]]> Sat, 08 Mar 2008 03:38:33 +0000 http://forum.codejock.com/forum_posts.asp?TID=9819&PID=32034&title=command-handler-design#32034 <![CDATA[Command handler design : Hi; the standard MFC message...]]> http://forum.codejock.com/forum_posts.asp?TID=9819&PID=31995&title=command-handler-design#31995 Author: mgampi

Hi;
the standard MFC message routine is first frame, then view then document if you have a doc/view architecture.
In most cases I handle the messages in my CDocument implementation, because the commands more or less manipulate the data I present in my views/controls.
When I don't have doc/view architecture, I handle command messages at place where they occure. The only difference here is, when the data is controlled by the parent/owner of the control.
 
To your second question:
Most of the time (95 out of 100) I use command handlers for popup menus also. IMHO this leads to a more readable and maintainable code.

I have a frame with a view, with a report control. On my menu I have five commands that somehow alter this report control. These commands are also accessable via a right-click menu in the report control.

1) Where should I put my command handlers? In the frame, the view or in the report control itself?
2) When showing the right-click menu, should I rely on the command handlers or should I explicitly check the return value of TrackPopupMenu()?
 
Are there any guidelines for this?
Thanks!
