Demo
一运用MFC AppWiard[exe]导游创立一个依据对话框的运用程序MySpin
二增加控件和变量

批改框 ID为ID_EDIT,成员变量 CEdit m_ctlEdit;
旋转按钮 ID为ID_SPIN,成员变量 CSpinButtonCtrl m_ctlSpin;
三设置旋转按钮特征

三在BOOL CSpinnDlg::OnInitDialog()增加代码，赤色有些
BOOL CSpinnDlg::OnInitDialog()
{
CDialog::OnInitDialog();
// Add "About..." menu item to system menu.
// IDM_ABOUTBOX must be in the system command range.
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
}
}
// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon
// TODO: Add extra initialization here
SetDlgItemText(IDC_EDIT, _T("0"));
//设置旋转按钮的方位方案
m_ctlSpin.SetRange(-100, 100);
//设置旋转按钮的其时方位
m_ctlSpin.SetPos(0);
//设置旋转按钮的其时基数
m_ctlSpin.SetBase(1);
//设置旋转按钮的火伴窗口
m_ctlSpin.SetBuddy(GetDlgItem(IDC_EDIT));
return TRUE; // return TRUE unless you set the focus to a control
}
