Example

In this example:

1. LMyDicomNet is a class derived from LDicomNet
2. LMyDicomNet has the following member variables:
   m_nClientOrServer: can be (STATUS_NONE, STATUS_SERVER, STATUS_CLIENT)
   identifies the LMyDicomNet object as a server or a client
   m_nDataCommand: can be (COMMAND_C_MOVE,COMMAND_C_GET)
   set so the server knows how a C-Store Response was generated

3. m_pDicomNet points to a valid LMyDicomNet object
   LMyDicomNet *m_pDicomNet

4. A connection exists between client and server

5. An association exists between the client and server
