LinkTopic 属性rn rnrn对于接收端控件－返回或设置发送端应用程序和主题（使用于该应用程序中的基本数据的分组）。为了指定完整的数据链，应当与 LinkItem 属性一起使用 LinkTopic。rnrn对于发送端窗体－返回或设置在 DDE 对话中发送端窗体需响应的主题。rnLinkTopic 属性由字符串组成，该字符串用来提供为建立接收端链或者发送端链必须的部分信息。该字符串依赖于正在使用的是接收端控件还是发送端窗体。每个字符串对应于标准 DDE 语法的一个或多个元素，它包括 application、topic和 item。rnrn注意 当 DDE 链接的标准定义包括 application、topic 和 item 元素时，对于接收端链接到发送端应用程序来说，应用程序内实际使用的语法可作少许的变更。例如，在 Microsoft Excel 中，可使用下面的语法：rnrnapplication|topic!itemrnrn而在 Microsoft Word for Windows 中，使用的是：rnrnapplication topic itemrnrn（不要使用管道符 [|] 或惊叹号 [!]。）rnrn在 Visual Basic 应用程序中，使用的是：rnrnapplication|topicrnrn惊叹号对于 topic 是隐含的。rnrnrnrn這到底是說什么呢?????

想实现自适应的带引用计数的智能指针，比如class A已实现引用计数功能，现在设计一个class A_var的智能指针，在A *pA=get()中已调用_add_ref(),A_var析构时自动调用A::_remove_ref()。参考了一下TAO中的TAO_Pseudo_Var_T,它居然有下面的代码:rnTAO_Pseudo_Var_T::TAO_Pseudo_Var_T (const TAO_Pseudo_Var_T & p)rn : ptr_ (T::_duplicate (p.ptr ()))rnrnrn想不通,既然T为非特化的，怎么可以调用T::_duplicate()呢？rnrn顺便请教一下实现自适应的带引用计数的类的智能指针如何实现为好？
