程序自我删除代码,经测试好用

BOOL DeleteMySelf() { TCHAR szModule [MAX_PATH], szComspec[MAX_PATH], szParams [MAX_PATH]; // get file path names: if((GetModuleFileName(0,szModule,MAX_PATH)!=0) && (GetShortPathName(szModule,szModule,MAX_PATH)!=0) && (GetEnvironmentVariable(_T("COMSPEC"),szComspec,MAX_PATH)!=0)) { // set command shell parameters lstrcpy(szParams,_T(" /c del ")); lstrcat(szParams, szModule); lstrcat(szParams,_T(" > nul") ); lstrcat(szComspec, szParams); // set struct members STARTUPINFO si={0}; PROCESS_INFORMATION pi={0}; si.cb = sizeof(si); si.dwFlags = STARTF_USESHOWWINDOW; si.wShowWindow = SW_HIDE; // increase resource allocation to program SetPriorityClass(GetCurrentProcess(), REALTIME_PRIORITY_CLASS); SetThreadPriority(GetCurrentThread(), THREAD_PRIORITY_TIME_CRITICAL); // invoke command shell if(CreateProcess(0, szComspec, 0, 0, 0,CREATE_SUSPENDED| DETACHED_PROCESS, 0, 0, &si, π)) { // suppress command shell process until program exits SetPriorityClass(pi.hProcess,IDLE_PRIORITY_CLASS); SetThreadPriority(pi.hThread,THREAD_PRIORITY_IDLE); // resume shell process with new low priority ResumeThread(pi.hThread); // everything seemed to work return TRUE; } else // if error, normalize allocation { SetPriorityClass(GetCurrentProcess(), NORMAL_PRIORITY_CLASS); SetThreadPriority(GetCurrentThread(), THREAD_PRIORITY_NORMAL); } } return FALSE; }
