HostReady Event

Summary

Occurs during a C-MOVE to oneself (the host) after the destination AE connects back to the host.

Syntax

C++/CLI

public event HostReadyDelegate HostReady

public:  
   event HostReadyDelegate^ HostReady

Remarks

When doing a C-MOVE Move to oneself, the destination AE is the same as the calling AE. In this case, the calling AE (i.e., the host) is listening and accepting incoming connections. After the destination AE connects back to the host, the host fires the HostReady event, and then the host accepts the client connection.
