BOOL bAutoDestroy=TRUE,
HBITMAP hBitmapHot=NULL,
BOOL bMap3dColors=TRUE,
HBITMAP hBitmapDisabled=NULL
);
void SetImage(
UINT uiBmpResId,
UINT uiBmpHotResId=0,
UINT uiBmpDsblResID=0
);

Example
The following example demonstrates how to use various versions of the SetImage method in the CMFCButton class. The example is part of the New Controls sample.
CMFCButton m_Button;
...
// int m_iImage
// IDB_BTN1_32, IDB_BTN1_HOT_32, IDB_BTN1, IDB_BTN1_HOT are int macros that are #define.
if (m_iImage == 1)
{
m_Button.SetImage((HBITMAP) NULL);
}
else
{
m_Button.SetImage(IDB_BTN1_32, IDB_BTN1_HOT_32);
}
