본문 Bitmap Button을 위한 Class는 CButton의 하위
클래스로 CBitmap Button이 있다.

To create a bitmap-button control in a window's client area, follow these steps:


1.Create one to four bitmap images for the button.
2.Construct the CBitmapButton object.
3.Call the Create function to create the Windows button  control and attach it to the CBitmapButton object.
4.Call the LoadBitmaps member function to load the bitmap  resources after the bitmap button is constructed.



To include a bitmap-button control in a dialog box, follow these steps:


1.Create one to four bitmap images for the button.
2.Create a dialog template with an owner-draw button  positioned where you want the bitmap button. The size of  the button in the template does not matter.
3.Set the button's caption to a value such as "MYIMAGE" and  define a symbol for the button such as IDC_MYIMAGE.
4.In your application's resource script, give each of the  images created for the button an ID constructed by  appending one of the letters "U," "D," "F," or "X" (for up,  down, focused, and disabled) to the string used for the  button caption in step 3. For the button caption "MYIMAGE,"  for example, the IDs would be "MYIMAGEU," "MYIMAGED,"  "MYIMAGEF," and "MYIMAGEX." You must specify the ID of your  bitmaps within double quotes. Otherwise the resource editor  will assign an integer to the resource and MFC will fail  when loading the image.
5.In your application's dialog class (derived from CDialog),  add a CBitmapButton member object.
6.In the CDialog object's OnInitDialog routine, call the  CBitmapButton object's AutoLoad function, using as  parameters the button's control ID and the CDialog object's  this pointer.

CButton::Create
BOOL Create( LPCTSTR lpszCaption, DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID );
example)

CBitmapButton::LoadBitmaps
BOOL LoadBitmaps( LPCTSTR lpszBitmapResource, LPCTSTR  lpszBitmapResourceSel = NULL, LPCTSTR  lpszBitmapResourceFocus = NULL, LPCTSTR  lpszBitmapResourceDisabled = NULL );
BOOL LoadBitmaps( UINT nIDBitmapResource, UINT  nIDBitmapResourceSel = 0, UINT nIDBitmapResourceFocus = 0,  UINT nIDBitmapResourceDisabled = 0 );

CBitmapButton::AutoLoad
BOOL AutoLoad( UINT nID, CWnd* pParent );

CBitmapButton::SizeToContent
void SizeToContent( );

example)
Resource에 bitmap을 추가하고, "COPYU","COPYD","COPYF","COPYE"
를 적절히 만든다.

CBitmapButton m_editCopy; 를 class에 추가한다.

OnInitDialog()안에
m_editCopy.AutoLoad(IDC_BUTTON1,this);
를 추가한다.
여기서, IDC_BUTTON1은 Button의 ID이며, 버튼의 속성에
Owner Draw를 추가해야 한다.
Button's Caption이 비트맵의 ID와 일치해야 한다.
여기서는 COPY라고 해야 한다.
(AutoLoad를 이용하면, Caption과 일치하는 비트맵을 찾는다.)

VERITY(m_editCopy.AutoLoad(IDC_BUTTON1,this));
로 하면, 비트맵을 못 찾을시에, 메시지 박스를 출력한다.
