最初是按照 FILE_FLAG_DELETE_ON_CLOSE的线索做的实验, 后来发现原始exe可以删除，但是克隆exe删不掉.
原因是进程在运行, 无法被删除.
后来在codeproject上看到释放.bat文件来删除主程序的方法. 这个方法实现, 思路明了. 实验的效果也不错.
/*****************************************************************************/ <2011_0206_2149><home><LostSpeed><程序自删除 V1.0.0.1> * 增加了DeleteMySelf()和支持的函数, 使程序自删除实现. * 建立了Console, Dialog, Sdi, Mdi工程, 分别做了测试, 自删除功能正常 * 主程序结束时, 在系统临时目录中建立了一个uuid.bat(名字是唯一的), 负责删除主程序, 用CreateProcess启动uuid.bat时, 隐藏了.bat的命令行窗口. 删除程序时的效果很棒, 看不到屏幕上有命令行窗口的闪烁. uuid.bat启动后, 循环检测主程序是否存在, 不停的删除主程序. 然后uuid.bat删除自己. * 如果收尾工作很繁杂, 可以另外做一个exe来做收尾工作(bat文件做的事还是有限), 把这个exe嵌到入主程序, 当程序退出时, 释放这个exe(没有窗口的console程序)到临时目录, 起名叫uuid.exe(保持文件名的唯一性), 然后建立,启动uuid.bat. uuid.bat启动这个收尾程序, 然后检测收尾程序是否结束. 如果结束, 删除收尾程序和uuid.bat /*****************************************************************************/

在Unicode字符集下编译不过, 找到UUID的新实现.

{ _TUCHAR *guidStr = NULL; std::wstring strW; GUID *pguid = new GUID; CoCreateGuid(pguid); // Convert the GUID to a string UuidToString(pguid, (RPC_WSTR*)&guidStr); delete pguid; strW = std::wstring(guidStr); return strW.c_str(); }
修正后的GenerateUniquePrefixName()实现
{ CString strUnique; GUID guid; HRESULT hRc = CoCreateGuid(&guid); if(S_OK != hRc) { strUnique.Format(_T("%d"), rand()); } else { _TUCHAR * str = NULL; UuidToString(&guid, (RPC_WSTR*)&str); strUnique = str; RpcStringFree((RPC_WSTR*)str); } return strUnique; } 现在用CString感觉很别扭了~
