如何在对话框中显示一行类似于网页上面的“链接”？

[shangke_sks]

类似于网页上面的“链接”，一行文字，当鼠标移动过去的时候，有下划线，点击的时候自动打开一个IE窗口……

谢谢：）

[shangke_sks]

多谢这位仁兄了，会不会有其它的比较简便的方法来实现这个功能啊？明天晚上结贴吧。

[alon21]

这个使用很简单的,把我上面贴的内容拷贝存为三个文件,加入你的工程,包含相应的头文件.
再就是我后面写出的使用方法了.

自己顶一下，怎么没人回呢？

使用方法

1.建立工程,将三个文件添加到工程里面

2.在对话框中添加3个Static,分别如下:
ID Title
IDC_PDURL WWW.ALON21.COM
IDC_PDURL1 Alon'Web
IDC_PDURL2 [e-mail]

3.在对话框类中添加成员变量:
public:
CStaticLink m_wndLink1;
CStaticLink m_wndLink2;
CStaticLink m_wndLink3;

4.在对话框类的OnInitDialog中添加代码:

m_wndLink2.m_link =_T("http://www.Alon21.com");
m_wndLink3.m_link = _T("mailto:[e-mail]");

m_wndLink1.SubclassDlgItem(IDC_PDURL,this);
m_wndLink2.SubclassDlgItem(IDC_PDURL1,this);
m_wndLink3.SubclassDlgItem(IDC_PDURL2,this);

谢谢，这个类很好用。

但是我做了一点修改，把void CStaticLink::OnLButtonDown( ) 改称OnLButtonUp()，觉得这样更合理些。
