Static COBJECT * PASCAL CREATEOBJECT ();

What is DECLARE_DYNAMIC?
defined as:
#define declare_dynamic (class_name) /
PUBLIC: /
Static const AFX_DATA CRUNTIMECLASS CLASS ## Class_name; /
Virtual cruntimeclass * getRuntimeClass () const; /
Then
Declare_Dynamic (MyDoc) /
Static COBJECT * PASCAL CREATEOBJECT ();
Equivalent to
PUBLIC: /
Static const AFX_DATA CRUNTIMECLASS Class ## mydoc; /
Virtual cruntimeclass * getRuntimeClass () const; /
Static COBJECT * PASCAL CREATEOBJECT ();
Then, according to
#define pascal __stdcall
#define AFX_CORE_DATA
#define AFX_DATA AFX_CORE_DATA
Explain that AFX_DATA is not
## is the connection character
Equivalent to
PUBLIC: /

Description CRUNTIMECLASS is a structure
Declare_DyncReate (MyDoc)
Be equivalent to
PUBLIC: /
Static const cantimeclass classmydoc; /
Virtual cruntimeclass * getRuntimeClass () const; / static cobject * __stdcall createObject ();
The three contents are defined, all of which are public members, a static structure, two functions.
