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.

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

L_VOID LMyDicomNet::OnReceiveData(L_UCHAR nID, LDicomDS *pCS, LDicomDS *pDS) 
{ 
   CString strMsg; 
   strMsg.Format(TEXT("*** OnReceiveData ***\nnID[%d]\n"), nID); 
    
   if (pCS)  
      strMsg += TEXT("Received a command set\n"); 
 
   if (pDS)  
      strMsg += TEXT("Received a data set\n"); 
   AfxMessageBox(strMsg); 
}
