BOOL CLoginDlg::OnInitDialog()

    CDialog::OnInitDialog();

    SetWindowLong(m_hWnd, GWL_HWNDPARENT, NULL);

    CRgnm_rgn;
    RECT rc;
    GetWindowRect(&rc); //有边框对话框 //GetClientRect(&rc);//无边框对话框 m_rgn.CreateRoundRectRgn(rc.left, rc.top, rc.right, rc.bottom, 100, 100); //矩形圆角 //m_rgn.CreateEllipticRgn(rc.left,rc.top,rc.right,rc.bottom);//椭圆  SetWindowRgn(m_rgn, TRUE); return TRUE; // return TRUE unless you set the focus to a control }
