无法管道传输CMD命令

Question

我想使用管道传输cmd的输出结果到控件上，但是发现在执行adb命令时提示创建进程错误，我要如何解决这个错误？
请修改下。adb shell getprop ro.product.model我想执行这个命令并在文本框输出命令执行结果（也就是手机型号），
是否有方法可以在控件输出adb命令执行结果？感谢
麻烦给出可以在MFC中运行的格式代码

TCHAR* StringToChar(CString& str)
{
    int len = str.GetLength();
    TCHAR* tr = str.GetBuffer(len);
    str.ReleaseBuffer();
    return tr;
}
CString executeCmd(CString command)
{

    //创建匿名管道
    HANDLE hReadPipe, hWritePipe;
    SECURITY_ATTRIBUTES safety;                        //安全属性    
    safety.nLength = sizeof(SECURITY_ATTRIBUTES);    //结构体大小
    safety.lpSecurityDescriptor = NULL;                //安全描述符，NULL；使用默认的
    safety.bInheritHandle = TRUE;                    //安全描述符的对象能否被子进程继承
    if (!CreatePipe(&hReadPipe, &hWritePipe, &safety, 0))
    {
        //创建管道错误
        return _T("创建管道错误！");
    }
    //创建进程
    TCHAR* cmdStr = StringToChar(command);
    STARTUPINFO startupInfo = { sizeof(startupInfo) };                    //进程信息    
    startupInfo.hStdError = hWritePipe;                                    //标志控制台窗口缓存
    startupInfo.hStdOutput = hWritePipe;                                //标志控制台窗口缓存
    startupInfo.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;    //使用wSHOWWIndows成员
    startupInfo.wShowWindow = SW_HIDE;
    PROCESS_INFORMATION pinfo;
    if (!CreateProcess(NULL, cmdStr, NULL, NULL, TRUE, NULL, NULL, NULL, &startupInfo, &pinfo))
    {
        //创建进程错误
        return _T("创建进程错误！");
    }
    CloseHandle(hWritePipe);

    //获取管道信息
    char buffer[4096];
    DWORD byteRead;
    CString output;                                    //返回值
    while (true)
    {
        memset(buffer, 0, 4096);                    //要放在循环里面，否则接收数据错乱
        if (ReadFile(hReadPipe, buffer, 4095, &byteRead, NULL) == NULL)
        {
            break;
        }
        output += buffer;
    }
    CloseHandle(hReadPipe);

    return output;

要在 MFC 中运行 ADB 命令“adb shell getprop ro.product.model”并在文本框中显示输出，您可以使用以下代码：

#include <afx.h>
#include <afxwin.h>
#include <Windows.h>
#include <iostream>
#include <string>

using namespace std;

void RunCmd(CString cmd, CEdit* pEdit) {
  SECURITY_ATTRIBUTES saAttr;
  saAttr.nLength = sizeof(SECURITY_ATTRIBUTES);
  saAttr.bInheritHandle = TRUE;
  saAttr.lpSecurityDescriptor = NULL;

  HANDLE hRead, hWrite;
  if (!CreatePipe(&hRead, &hWrite, &saAttr, 0)) {
    pEdit->SetWindowTextW(L"Error creating pipe");
    return;
  }

  STARTUPINFOW siStartupInfo;
  ZeroMemory(&siStartupInfo, sizeof(STARTUPINFOW));
  siStartupInfo.cb = sizeof(STARTUPINFOW);
  siStartupInfo.dwFlags = STARTF_USESHOWWINDOW | STARTF_USESTDHANDLES;
  siStartupInfo.wShowWindow = SW_HIDE;
  siStartupInfo.hStdOutput = hWrite;
  siStartupInfo.hStdError = hWrite;

  PROCESS_INFORMATION piProcessInfo;
  ZeroMemory(&piProcessInfo, sizeof(PROCESS_INFORMATION));

  wchar_t buffer[4096];
  wcscpy_s(buffer, cmd);

  if (!CreateProcessW(NULL, buffer, NULL, NULL, TRUE, 0, NULL, NULL, &siStartupInfo, &piProcessInfo)) {
    pEdit->SetWindowTextW(L"Error creating process");
    return;
  }

  CloseHandle(hWrite);

  DWORD dwRead;
  string strOutput;
  while (ReadFile(hRead, buffer, 4096, &dwRead, NULL)) {
    strOutput.append(buffer, dwRead);
  }

  pEdit->SetWindowTextW(strOutput.c_str());

  CloseHandle(hRead);
  CloseHandle(piProcessInfo.hProcess);
  CloseHandle(piProcessInfo.hThread);
}

// Example usage:
void CMyDlg::OnBtnClick() {
  RunCmd(_T("adb shell getprop ro.product.model"), &m_edit);
}

请注意，此代码假定 ADB 可执行文件位于系统 PATH 中。如果不是，则需要在命令字符串中指定 ADB 可执行文件的完整路径。
