只有BCB的代码,这个是用CHM的上下文关联做的,还需要在控件的HELPCONTEXT中设置关联
void __fastcall TForm1::MyHelp(Messages::TMessage &Message)
{
    HELPINFO *HI = (HELPINFO*)Message.LParam;
    TWinControl *WC;
    TMenuItem *MI;
    TMenu *Menu;
    // 主菜单上传来的WM_HELP消息
    if(HI->iContextType == HELPINFO_MENUITEM)
    {
        for(int i=0; i<this->ComponentCount; i++)
        {
            Menu = dynamic_cast<TMenu *>(this->Components[i]);
            if(Menu != NULL)
            {
                MI = Menu->FindItem(HI->iCtrlId, fkCommand);
                if(MI != NULL)
                {
                    break;
                }
            }
        }
        if(MI != NULL && MI->HelpContext != 0)
        {
            HtmlHelp(this->Handle, Application->HelpFile.c_str(), HH_HELP_CONTEXT, MI->HelpContext);
        }
        else
        {
            HtmlHelp(this->Handle, Application->HelpFile.c_str(), HH_DISPLAY_TOPIC, 0);
        }    }
    // 活动控件上传来的WM_HELP消息
    else
    {
        WC = FindControl(HI->hItemHandle);
        if(WC != NULL && WC->HelpContext != 0)
        {
            HtmlHelp(this->Handle, Application->HelpFile.c_str(), HH_HELP_CONTEXT, WC->HelpContext);
        }
        else
        {
            HtmlHelp(this->Handle, Application->HelpFile.c_str(), HH_DISPLAY_TOPIC, 0);
        }
    }
}
