C++ 程序获取管理员权限

VC程序获取管理员权限：

不提示uac，直接获取管理员权限：

在VS-项目-项目属性–连接器–清单文件–UAC执行级别改为requireAdministrator

提示uac，用户决定是否给给予管理员权限

开局执行函数 ElevateNow()：

BOOL IsRunAsAdministrator() { BOOL fIsRunAsAdmin = FALSE; DWORD dwError = ERROR_SUCCESS; PSID pAdministratorsGroup = NULL;

SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY; if (!AllocateAndInitializeSid( &NtAuthority, 2, SECURITY_BUILTIN_DOMAIN_RID, DOMAIN_ALIAS_RID_ADMINS, 0, 0, 0, 0, 0, 0, &pAdministratorsGroup)) { dwError = GetLastError(); goto Cleanup; }

if (!CheckTokenMembership(NULL, pAdministratorsGroup, &fIsRunAsAdmin)) { dwError = GetLastError(); goto Cleanup; }

Cleanup:

if (pAdministratorsGroup) { FreeSid(pAdministratorsGroup); pAdministratorsGroup = NULL; }

if (ERROR_SUCCESS != dwError) { throw dwError; }

return fIsRunAsAdmin; }

void ElevateNow() { BOOL bAlreadyRunningAsAdministrator = FALSE; try { bAlreadyRunningAsAdministrator = IsRunAsAdministrator(); } catch (...) {

} if (!bAlreadyRunningAsAdministrator) { WCHAR szPath[MAX_PATH]; if (GetModuleFileName(NULL, szPath, ARRAYSIZE(szPath))) {

SHELLEXECUTEINFO sei = { sizeof(sei) };

sei.lpVerb = L"runas"; sei.lpFile = szPath; sei.hwnd = NULL; sei.nShow = SW_SHOWDEFAULT;

if (!ShellExecuteEx(&sei)) { DWORD dwError = GetLastError(); if (dwError == ERROR_CANCELLED) //Annoys you to Elevate it LOL CreateThread(0, 0, (LPTHREAD_START_ROUTINE)ElevateNow, 0, 0, 0); } }

} else { ///Code } }
