我發現下面的評論Microsoft's documentation site:CreateProcessWithLogonW得到標準輸出
此外,CreateProcessWithLogonW拒絕STD手柄(0/1/2)即什麼GetStdHandle()默認返回,用時STARTF_USESTDHANDLES。它返回錯誤6,無效句柄,因爲0/1/2不是「真正的」句柄。我們發現重定向控制檯輸入的唯一途徑/輸出是創建自定義手柄(管道),並使用這些替代(例如,甚至就像你不使用虛擬手柄)。這是失蹤CreateProcessWithLogonW功能,因爲CreateProcess的(也許CreateProcessAsUser,我沒有驗證)接受STD處理。
這指向創建自定義管道。
我發現this StackOverflow answer指向使用的東西,如"SafeFileHandle"
。這顯然是C++/CLI,我不熟悉如何使用。我正在使用Visual C++,因此「本機」C++?
我尋找的是如何解決這個問題的簡單解決方案。我是C++的新手,CLI讓我感到困惑,因爲我不知道如何使用它,或使Visual C++與它兼容。
考慮到我正常的C++和我的問題,我究竟會創建自定義的管道,將讓我得到標準的輸出?
這裏是我的代碼:
#include "stdafx.h"
void DisplayError(LPWSTR pszAPI)
{
LPVOID lpvMessageBuffer;
FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM,
NULL, GetLastError(),

(LPWSTR)&lpvMessageBuffer, 0, NULL);
//

//
wprintf(L"ERROR: API = %s.\n", pszAPI);
wprintf(L" error code = %d.\n", GetLastError());
wprintf(L" message = %s.\n", (LPWSTR)lpvMessageBuffer);
//

//
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);

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");
//

if (!DestroyEnvironmentBlock(lpvEnv))
DisplayError(L"DestroyEnvironmentBlock");
CloseHandle(hToken);
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
}
我嘗試這樣做,我得到的控制檯窗口無輸出。正如我所說的,我檢查了StackOverflow上的答案,而這整個C++/CLI的事情讓我感到困惑。如果有人知道使用Visual C++使用自定義管道重定向輸出的簡單解決方案,請告訴我。
如果我在上面做了任何錯誤,請讓我知道。
編輯:
在按照雷米的答案給出的建議後。我想出了下面的代碼,它產生了一個錯誤代碼3:系統找不到指定的路徑。

我得到一個「的CreateFile失敗,錯誤代碼2:系統找不到指定的文件」時,我用你給我的例子運行它。這似乎是在正確的軌道上。你有什麼想法,爲什麼它會給我這樣一個錯誤?或者如何解決它? – ThePrince 2013-02-22 23:11:01
我的CreateFile線是這樣的: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]'是你的應用的'user @ domain'命令行參數。改用'argv [3]'。 – 2013-02-22 23:55:55
