没有显示窗口C＃应用程序处理中的telnet

问题描述：


我有一个很奇怪的问题，我的C＃应用​​程序之一：
没有显示窗口C＃应用程序处理中的telnet

它的主要目的是为每[user32.dll] SendMessage发送命令。这在常规机器上或从批处理文件或命令行窗口启动时没有问题。

如果我从Telnet，SSH或PHP的shell_exec()执行我的应用程序，应用程序无法找到目标窗口句柄，即使它可以找到目标进程。

我已经写了一段测试代码向你展示我的问题：

public static int Main(string[] argv) 
{ 
    foreach (Process p in Process.GetProcesses()) 
     Console.Write(p.MainWindowHandle.ToInt32().ToString("x8") + " - " + p.ProcessName + "\n"); 

    Console.ReadKey(true); 

    return 0; 
}

结果是在“正常”的方式执行时，以下几点：

正如你所看到的 - 有很多没有窗口句柄的进程，但像VisualStudio（devnev）这样的进程有一个。
如果我运行相同的命令通过量的Telnet，SSH等我得到以下结果：

正如你可以看到，每一道工序 - 除了cmd - 已经没有窗口句柄。
我的问题是：我该如何解决这个问题？或者Windows以某种方式阻止通过Telnet访问窗口？

非常感谢你

Telnet运行在与你的用户会话不同的Windows会话中。通常，所有服务都在会话0上运行，并且所有用户应用程序都在会话1+中运行。当您运行应用程序时，您只能看到与您的应用程序在同一个会话中运行的那些窗口名称。阅读更多关于恼人的Windows'会话机制（尝试谷歌它）。
