Parameters
error


An error code.
type


The type of data that was sent.
length


The number of bytes of the data actually sent.
net


The DicomNet object of the peer member of the connection.

            
            

            
            
            
            
Remarks
When one of the DicomNet.SendXXX methods is called, the message is not sent immediately. It is placed in a network queue and sent later. When the data is actually sent, this method is called to let the calling AE know that the data has been sent.


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