MFC. CDialogEx, CDialog

	개요
	CDialogEx 는 CDialog 에서 파생된 클래스이며, 대화상자 배경색변경, 배경이미지 추가가 간편해진것이므로 기존 CDialog 로 생성하던 것을 CDialogEx 로 생성하는 것은 아무 문제 일으키지 않음. Public Methods Name Description CDialogEx::SetBackgroundColor Sets the background color of the dialog box. CDialogEx::SetBackgroundImage Sets the background image of the dialog box.                   Dialog box images are stored in a resource file. The framework automatically deletes any image that is loaded from the resource file. To programmatically delete the current background image, call the CDialogEx::SetBackgroundImage method or implement an OnDestroy event handler. When you call the CDialogEx::SetBackgroundImage method, pass in an HBITMAP parameter as the image handle. The CDialogEx object will take ownership of the image and delete it if the m_bAutoDestroyBmp flag is TRUE.
