virtual BOOL Create(
LPCTSTR lpszCaption,
DWORD dwStyle,
const RECT& rect, //we need to pass a RECT instance
CWnd* pParentWnd,
UINT nID
);
// Create a push button.
myButton1.Create(_T("My button"), WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,
CRect(10,10,100,30), pParentWnd, 1);
CRect(10,10,100,30)
is a constructor,does this mean the constructor return a instance?

//CRect(10,10,100,30) is a constructor...
No it is not. It is the declaration of an object. It does call the constructor but the object is created locally, not returned by the constructor.

This code is equivalent to the following :
CRect rect = CRect(10,10,100,30);
// Create a push button.
myButton1.Create(_T("My button"), WS_CHILD|WS_VISIBLE|BS_PUSHBUTTON,
rect, pParentWnd, 1);
The constructor returns an instance of the class it is constructed, which is used by the Create function.
