The CBitmapButton MFC class makes it easy to create buttons with custom bitmaps. It is easy to use if you know how to. The documentation says to use CBitmapButton::AutoLoad but I do not understand how to use it. The following is what worked for me.

1. Set the "Owner draw" style for the button on
2. Use the ClassWizard to create a class derived from CButton
3. In the header of the derived class change the class from CButton to CBitmapButton
4. Use ClassWizard again to create a "control category" member variable for the button; ensure that the class is the derived class you just created
5. In the dialog's OnInitDialog use CBitmapButton::LoadBitmaps to load one or more bitmaps

An example of LoadBitmaps is:

if (!m_ctlPictureButton1.LoadBitmaps(_T("IMAGE1UP"), _T("IMAGE1DOWN"), _T("IMAGE1FOCUS")))
	MessageBox("Button1 pictures are not loaded");
