一个完整的用法示例
以下示例为一个完整的用法展示，实现了调用第三方工具 devocn.exe 安装虚拟网卡（不展示安装界面）并通过获取安装进程句柄判断安装结果。
SEE_MASK_NOCLOSEPROCESS参数：表示要获取进程句柄- 通过
GetExitCodeProcess函数获取进程执行状态 SW_HIDE参数: 不展示窗口
#define QREINSTALL_NETCARD_TOOLS_NAME L"devcon.exe"
std::mutex g_mutex_nc_install;
bool InstallNcDrive(bool &bRes, bool &bEnd)
{
std::lock_guard<std::mutex> lock(g_mutex_nc_install);
bool bOptRt = false;
//触发重新安装虚拟网卡
TCHAR szPath[MAX_PATH];
::GetModuleFileName(NULL, szPath, MAX_PATH);
::PathRemoveFileSpec(szPath);
QLOG_INFO() << "tools[devcon.exe]'s path is" << QString::fromWCharArray(szPath);
std::string command = " install vpnvnic.inf vpnvnic";
SHELLEXECUTEINFO ShExecInfoInstall = { 0 };
try
{
ShExecInfoInstall.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfoInstall.fMask = SEE_MASK_NOCLOSEPROCESS;

}

ShExecInfoInstall.nShow = SW_HIDE;
ShExecInfoInstall.hInstApp = NULL;
ShExecInfoInstall.hProcess = NULL;
bOptRt = ShellExecuteEx(&ShExecInfoInstall);
if (bOptRt)
{
QLOG_INFO() << "驱动安装进程已启动！";
// 等待进程结束
WaitForSingleObject(ShExecInfoInstall.hProcess, INFINITE);
// 获取退出代码
DWORD exitCode;
if (GetExitCodeProcess(ShExecInfoInstall.hProcess, &exitCode))
{
// 判断进程是否成功退出
if (exitCode != STILL_ACTIVE)

}
else
{
QLOG_INFO() << "驱动安装进程未能正常退出，退出代码: " << exitCode;
}
}
else
{
QLOG_INFO() << "获取驱动安装进程退出代码失败！错误代码: " << GetLastError();
}
// 实测 1和0 的时候安装成功
bRes = exitCode == 1 || exitCode == 0 ? true : false;
// 关闭句柄
CloseHandle(ShExecInfoInstall.hProcess);
}

}
}

return bOptRt;
}
