Comments

This is a low level means of receiving DICOM messages and data. It allows you to process messages yourself, instead of using the high level message processing functions provided.

This function is generated for each LDicomNet::SendXXX function provided by LEADTOOLS.

Receiving Messages

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

//OnReceive()
