SendNSetRequest Example for C++ 6.0 or later
{
//This example sends a N-Set Request to a server
//
//In this example:
//1. m_Dicom, m_Dicom2 are LEAD ActiveX Dicom objects (CLEADDICOM)
//
//2. m_DicomNet is LEAD ActiveX DicomNet object (CLEADDICOMNet)
//
//3. m_nClientOrServer: can be (STATUS_NONE, STATUS_SERVER, STATUS_CLIENT)
// identifieds the LMyDicomNet object as a server or a client
//4. m_nDataCommand: can be (COMMAND_C_MOVE,COMMAND_C_GET)
// set so the server knows how a C-Store Response was generated
//
//5. A connection exists between client and server
//6. An association exists between the client and server
