请问 这么给CAboutDlg类添加析构函数
我手动加了一个
CAboutDlg::~CAboutDlg()
{ }

出错！

E:\vc\练习\tooltips\tooltips.cpp(145) : error C2084: function '__thiscall CAboutDlg::~CAboutDlg(void)' already has a body
E:\vc\练习\tooltips\tooltips.cpp(165) : error C2264: 'CAboutDlg::~CAboutDlg' : error in function definition or declaration; function not called
Error executing cl.exe.

tooltips.exe - 2 error(s), 0 warning(s)

谢谢 ！
忘了定义了，真是晕了！
