MFC设置按钮ICON

 说明：IDI_ICON1是ICON ID ,IDC_BUTTON1是BUTTON ID

 环境：VS2005 MFC 

解决方案：

  HICON hIcon;

  hIcon=AfxGetApp()->LoadIcon(IDI_ICON1);

  GetDlgItem(IDC_BUTTON1)->ModifyStyle(0, BS_ICON, 0);

  GetDlgItem(IDC_BUTTON1)->SendMessage(BM_SETIMAGE,  (WPARAM)IMAGE_ICON, (LPARAM)hIcon );

错误的方案：

  m_hIcon = AfxGetApp()->LoadIcon(IDI_ICON1); 

  GetDlgItem(IDC_BUTTON1)->SetIcon(m_hIcon, TRUE);

  GetDlgItem(IDC_BUTTON1)->SetIcon(LoadIcon(AfxGetResourceHandle(),MAKEINTRESOURCE(IDI_ICON1)),TRUE);
