向导生成器的上下文敏感帮助


问:如何在向导生成器中加入上下文帮助以及关闭按钮,这好象不是缺省值.

答:你需要处理WS_SYSMENU类型

BOOL CYourPropertySheet::OnInitDialog()
{
    if (CPropertySheet::OnInitDialog())
    {
        ModifyStyle(0, WS_SYSMENU, 0);
        ModifyStyleEx(0, WS_EX_CONTEXTHELP, 0);

        // The default system menu has several menu items that don't make
        // sense for a wizard. Remove them.
        Cmenu* pSystemMenu = GetSystemMenu(FALSE);
        if (pSystemMenu != NULL)
        {
            // Remove some items
            pSystemMenu->DeleteMenu(SC_RESTORE, MF_BYCOMMAND);
            pSystemMenu->DeleteMenu(SC_SIZE, MF_BYCOMMAND);
            pSystemMenu->DeleteMenu(SC_MINIMIZE, MF_BYCOMMAND);
            pSystemMenu->DeleteMenu(SC_MAXIMIZE, MF_BYCOMMAND);

            // Do not remove/hide SC_CLOSE, or the '?' icon won't be
            // drawn properly
        }
        // ... Other initialization, like maybe Q143210
        return TRUE;
    }
    else
        return FALSE;
}
