Example

This example sends an N-Create Request to a server 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
