VC++信息安全编程（2）分析程序实现自我删除

1、vc+信息安全编程（2）分析程序实现自我删除无数时候，我们制作自动安装程序，安装完成以后自动删除，软件仅仅安装一次就自动删除，以庇护软件学问产权。软件自动删除的代码是如何实现的呢，我们来看下ifdef _debug define new debug_new undef this_file ic char this_file = _file_; endif / / cselfdeldlg dialog cselfdeldlg:cselfdeldlg(cwnd* pparent /*=null*/) : cdialog(cselfdeldlg:idd, pparent) /afx_data_ini
