推荐答案

您好
Tim Jansen ，

感谢您在此处分享您的问题。

Thank you for sharing your issue on here.

这是发展问题的正确论坛。

Here is correct forum for developing issue.

>>"由此我们得出结论，RPCSS服务必须发送ping消息。这是正确的吗？ "

>>" From this we conclude that the RPCSS service must be sending the ping messages. Is this correct? "

据我所知，DCOM为组件提供自动垃圾回收，  DCOM使用pinging协议来检测客户端是否处于活动状态。 客户端计算机定期向DCOM服务器发送ping消息。  

As far as I know that DCOM provides automatic garbage collection for components ,  DCOM uses a pinging protocol to detect if client are live.  A client machine periodically sends a ping message to the DCOM server.  

如果DCOM服务器连续3次没有收到ping消息，则假定客户端已经死亡。  DCOM假定与客户端断开连接。  DCOM会自动减少死客户使用的
组件的引用计数。  

If the ping message is NOT received by the DCOM server 3 times in a row then the client is assumed to be dead.  DCOM assumes that the connection is broken with the client.  DCOM automatically decrements the reference count of the component used by the dead client.  

因此服务无法将ping消息发送给客户端。 ping消息必须从客户端发送。

So the service cannot send the ping message to client. the ping message must be sent from client.

>>"是否有关于如何从客户端应用程序和客户端计算机的角度运行ping操作的详细文档？  "

>>" Is there detailed documentation about how the pinging mechanism works from the perspective of the client application and client machine?  "

您可以参考
文件。

>>"  可以阻止单线程单元中的线程导致所描述的断开连接问题吗？  "

>>"  Can blocking a thread in a single threaded apartment cause the described disconnect problem?  "

如果要阻止线程等待其他。 你可以使用
WaitForObject 方法。  为确保您的对象不会无意中阻止自身或公寓中的其他对象，请在挂起线程执行时始终使用
MsgWaitForObject 或 MsgWaitForMultipleObjects 。

If you want to block the thread for waiting other.  you could use the WaitForObject method.  To ensure that your object does not inadvertently block itself or other objects in the apartment, always use MsgWaitForObject or MsgWaitForMultipleObjects when suspending thread execution.

最好的问候，

Hart
