/*
 *	File:		detail_dlg.h
 *	Function:	make a dialog can extend and shrine
 *	Usage:		create a dialog derive from this, like:
				class CTestDlg: detail_dlg<CDialog>
				{
					...
				};
				and place a separator line in the dialog, named "ID_SEP"
				then in the dialog constructor:
				CTestDlg::CTestDlg(CWnd* parent = NULL ):
				base(ID_SEP, CTestDlg::IDD, parent)
				{
					...
				}
				ok, now use "simple()" and "detail()" freely. isnt it wonderful?
