Comments

When one of the LDicomNet::SendXXX functions 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 callback function is called to let the calling AE know that the data has been sent.

To customize this function, you must derive a class from LDicomNet and override this function.

Example

LMyDicomNet is a class derived from LDicomNet
In class LMyDicomNet, all events (virtual functions OnXXX()) have been overridden so that they can be processed. Each event displays a MessageBox identifying the event, the IP that generated the event, the IP that received the event and any other relevant data.
For the entire derived class, see (hyperlink)LMyDicomNet class
