Hi
I have a basic question about MFC.
There are 4 sections in Properties windows
-Properties
-Events
-Messages
-Overrides

For example: For CView class
OnDraw is in overrides section. But OnDrawItem is in messages section.
Why is it so?

Some methods are in mesages section(handle with message map) some are virtual.
What is the logic behind this separation?

sawer:

Even more important than why it is this way is the effect it has on the IDE. If
you select the Properties of a dialog while you are looking at a dialog template
in the resource editor, then you will be able to add messages, but not
overrides. In cases like WM_INITDIALOG that you might have expected to be a
message handler, this is a real inconvenience.

I would suggest that the virtual overrides should also be present in this situation:

IMHO, a lot (though not all) of the problem with the "new" Visual Studio IDE has
to do with accessibility rather than functionality.
