控件子类化的问题！！！！

[jacky1019]

我用CStatic做基类在工程中新插入了一个CHyperlinkStatic类，就是想模仿网页上的那种超链接邮件地址，我在该类中处理了WM_MOUSEMOVE消息，然后将AboutDialog中的某个文本框映射为CHyperlinkStatic类，但当鼠标移过的时候却没有动静，我又测试了其它的诸如WM_LBUTTONDOWN的消息也没有响应。然而，我直接在constructor函数中加入测试语句的话又有响应，真搞不懂是为什么？

我把代码大致贴出来，请大侠帮我分析一下！

CHyperlinkStatic.h:

#if !defined(AFX_HYPERLINKSTATIC_H__09998C61_5522_408A_A670_A815C41FA0FD__INCLUDED_)

在你的rc中，单击你的静态控件，右键选择属性，选中Styles中的Notify!

ok，你的问题解决了~~~~~~~~

[So1o]

或者在Style里加上 SS_NOTIFY
