与本地运行相比,在通过WMI运行时,可执行程序的行为有所不同

我将以下c sharp文件编译为可执行文件。

using System;
using System.Runtime.InteropServices;
using System.Text;
using System.IO;
using System.Threading;

namespace Foreground {
  class GetForegroundWindowTest {

    [DllImport("user32.dll", CharSet=CharSet.Auto, ExactSpelling=true)]
    public static extern IntPtr GetForegroundWindow();

    [DllImport("user32.dll", CharSet=CharSet.Unicode, SetLastError=true)]
    public static extern int GetWindowText(IntPtr hWnd, StringBuilder lpString, int nMaxCount);

    public static void Main(string[] args){
        while (true){
            IntPtr fg = GetForegroundWindow(); //use fg for some purpose

            var bufferSize = 1000;
            var sb = new StringBuilder(bufferSize);

            GetWindowText(fg, sb, bufferSize);

            using (StreamWriter sw = File.AppendText("C:\\Office Viewer\\OV_Log.txt")) 
            {
                sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd_HH:mm:ss,") + sb.ToString());
            }

            Thread.Sleep(5000);
        }
    }
  }
}

当我在本地计算机上运行此可执行文件时,它会生成当前窗口的日期和名称。

当我使用wmi从远程计算机运行此可执行文件时,它会生成日期,当前窗口的名称为空,我认为这意味着它返回null。有人有解决方法吗?

运行wmi可执行文件的程序是用python编写的,格式如下:

import wmi

IP         = '192.168.165.x'
USERNAME   = 'username'
PASSWORD   = 'password'
REMOTE_DIR = 'c:\ ... \'

remote_pc = wmi.WMI (IP, user = USERNAME, password = PASSWORD)

exe_remote_path = join (['\\\\', IP, '\\', REMOTE_DIR, filename)

remote_pc.Win32_Process.Create (CommandLine = exe_remote_path)

这可能是问题.....

  

出于安全原因,Win32_Process.Create方法不能用于远程启动交互式进程。
