LParam属性对应的lParam成员结构的定义为 Microsoft Windows 操作系统的一部分。如果事件处理程序正在处理OnKeystrokeMessageForAddon事件,Microsoft Visio 将作为参数传递MSGWrap对象时将引发此事件。MSGWrap对象是 Windows消息周围的包装结构。The lParam property corresponds to the lParam member of the MSG structure defined as part of the Microsoft Windows operating system. If an event handler is handling the OnKeystrokeMessageForAddon event, Microsoft Visio passes a MSGWrap object as an argument when this event fires. A MSGWrap object is a wrapper around the Windows MSG structure.
