RE: [Dev-C++] scope resolution +1

[Graeme F. <gr...@dr...>]

The CDialog1::CDialog1(CWnd* pParent /*=NULL*/) is the constructor for the
CDialog1 class. Now because this class will inherit from the CDialog class
it must be able to call the default constructor for the CDialog class.
However this class probably doesn't have a default constructor, in which
case the constructor has to be called explicitly, hence the line :
CDialog(CDialog1::IDD, pParent) which calls the CDialog constructor passing
it IDD a static variable from CDialog and pParent argument passed in. Now
that the CDialog constructor has been called the rest of the CDialog1
constructor can be executed.
