Parameters
error


An error code.
net


The DicomNet object of the peer member of the connection.

            
            

            
            
            
            
Remarks
A call to this method is generated by a call to DicomNet.Close. The OnClose method is useful to both SCUs and SCPs.


To customize this method, you must derive a class from DicomNet and override this method.
