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
}
}
