我发现下面的评论Microsoft's documentation site:CreateProcessWithLogonW得到标准输出
此外,CreateProcessWithLogonW拒绝STD手柄(0/1/2)即什么GetStdHandle()默认返回,用时STARTF_USESTDHANDLES。它返回错误6,无效句柄,因为0/1/2不是“真正的”句柄。我们发现重定向控制台输入的唯一途径/输出是创建自定义手柄(管道),并使用这些替代(例如,甚至就像你不使用虚拟手柄)。这是失踪CreateProcessWithLogonW功能,因为CreateProcess的(也许CreateProcessAsUser,我没有验证)接受STD处理。
这指向创建自定义管道。
我发现this StackOverflow answer指向使用的东西,如"SafeFileHandle"
。这显然是C++/CLI,我不熟悉如何使用。我正在使用Visual C++,因此“本机”C++?
我寻找的是如何解决这个问题的简单解决方案。我是C++的新手,CLI让我感到困惑,因为我不知道如何使用它,或使Visual C++与它兼容。
考虑到我正常的C++和我的问题,我究竟会创建自定义的管道,将让我得到标准的输出?
这里是我的代码:
#include "stdafx.h"
void DisplayError(LPWSTR pszAPI)
{
LPVOID lpvMessageBuffer;
FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM,
NULL, GetLastError(),
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
(LPWSTR)&lpvMessageBuffer, 0, NULL);
//
//... now display this string
//
wprintf(L"ERROR: API = %s.\n", pszAPI);
wprintf(L" error code = %d.\n", GetLastError());
wprintf(L" message = %s.\n", (LPWSTR)lpvMessageBuffer);
//
// Free the buffer allocated by the system
//
LocalFree(lpvMessageBuffer);
ExitProcess(GetLastError());
}
void _tmain(int argc, WCHAR *argv[])
{
STARTUPINFO si;
ZeroMemory(&si, sizeof(STARTUPINFO));
si.cb = sizeof(STARTUPINFO);
HANDLE pipe1 = CreateNamedPipe(L"\\\\.\\pipe\\pipe1", PIPE_ACCESS_DUPLEX,
PIPE_WAIT, 1024, 1024, 1024, 60, NULL);
HANDLE pipe2 = CreateNamedPipe(L"\\\\.\\pipe\\pipe2", PIPE_ACCESS_DUPLEX,
PIPE_WAIT, 1024, 1024, 1024, 60, NULL);
si.dwFlags |= STARTF_USESHOWWINDOW;
si.dwFlags = STARTF_USESTDHANDLES;
si.hStdOutput = pipe1;
si.hStdError = pipe2;
DWORD dwSize;
HANDLE hToken;
LPVOID lpvEnv;
PROCESS_INFORMATION pi = {0};
WCHAR szUserProfile[256] = L"";
si.cb = sizeof(STARTUPINFO);
if (argc != 4)
{
wprintf(L"Usage: %s [[email protected]] [password] [cmd]", argv[0]);
wprintf(L"\n\n");
return;
}
//
// TO DO: change NULL to '.' to use local account database
//
if (!LogonUser(argv[1], NULL, argv[2], LOGON32_LOGON_INTERACTIVE,
LOGON32_PROVIDER_DEFAULT, &hToken))
DisplayError(L"LogonUser");
if (!CreateEnvironmentBlock(&lpvEnv, hToken, TRUE))
DisplayError(L"CreateEnvironmentBlock");
dwSize = sizeof(szUserProfile)/sizeof(WCHAR);
if (!GetUserProfileDirectory(hToken, szUserProfile, &dwSize))
DisplayError(L"GetUserProfileDirectory");
//
// TO DO: change NULL to '.' to use local account database
//
if (!CreateProcessWithLogonW(argv[1], NULL, argv[2],
LOGON_WITH_PROFILE, NULL, argv[3],
CREATE_UNICODE_ENVIRONMENT, lpvEnv, szUserProfile,

DisplayError(L"CreateProcessWithLogonW");
if (!DestroyEnvironmentBlock(lpvEnv))
DisplayError(L"DestroyEnvironmentBlock");
CloseHandle(hToken);
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
}
我尝试这样做,我得到的控制台窗口无输出。正如我所说的,我检查了StackOverflow上的答案,而这整个C++/CLI的事情让我感到困惑。如果有人知道使用Visual C++使用自定义管道重定向输出的简单解决方案,请告诉我。
如果我在上面做了任何错误,请让我知道。
编辑:
在按照雷米的答案给出的建议后。我想出了下面的代码,它产生了一个错误代码3:系统找不到指定的路径。

我得到一个“的CreateFile失败,错误代码2:系统找不到指定的文件”时,我用你给我的例子运行它。这似乎是在正确的轨道上。你有什么想法,为什么它会给我这样一个错误?或者如何解决它? – ThePrince 2013-02-22 23:11:01
我的CreateFile线是这样的:g_hInputFile =的CreateFile( 的argv [1], GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_READONLY, NULL); – ThePrince 2013-02-22 23:12:50
'argv [1]'是你的应用的'user @ domain'命令行参数。改用'argv [3]'。 – 2013-02-22 23:55:55
