LDicomNet::OnReceiveNDeleteRequest

#include "ltdic.h"

virtual L_VOID LDicomNet::OnReceiveNDeleteRequest(nPresentationID, nMessageID, pszClass, pszInstance)

Notifies a connection that an N-DELETE-REQ command was received. This function is available in the PACS Imaging Toolkit.

Parameters

L_UCHAR nPresentationID

Presentation ID. The presentation ID provides information about both the class type of the data and the transfer syntax to use when transferring the data.

L_UINT16 nMessageID

Message ID. Each message sent by a member of a connection should have a unique ID. Since a member of a connection may send several messages, this ID allows that member to identify when a specific request has been completed.

L_TCHAR * pszClass

Class affected by the request. This will be an SOP Class or an SOP MetaClass.

L_TCHAR * pszInstance

The instance of the class. A server may, for example, have three instances of the Nuclear Medicine Class. This value specifies an instance.

Returns

None.

Comments

A call to this function is generated on a peer member of a connection when LDicomNet::SendNDeleteRequest is called locally.

To customize this function, you must derive a class from LDicomNet and override this function.

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
    L_VOID LMyDicomNet::OnReceiveNDeleteRequest(L_UCHAR nPresentationID, L_UINT16 nMessageID, L_TCHAR *pszClass, L_TCHAR *pszInstance) 
    { 
       CString strMsg; 
       L_UINT  lPeerPort; 
       L_TCHAR  szPeerAddress[100]; 
     
       GetPeerInfo(szPeerAddress,100, &lPeerPort); 
       strMsg.Format(TEXT("*** OnReceiveNDeleteRequest ***\nPeer[%s]\nnPresentationID[%d]\nnMessageID[%d]\npszClass[%s]\npszInstance[%s]"),  
                    szPeerAddress, 
                    nPresentationID,  
                    nMessageID,  
                    pszClass, 
                    pszInstance); 
     
       //... 
       //... Do the delete 
       //... 
     
       //send a delete response 
       L_UINT16 nStatus = COMMAND_STATUS_SUCCESS; 
       SendNDeleteResponse(nPresentationID, nMessageID, pszClass, pszInstance, nStatus); 
     
       strMsg = strMsg + "SendNDeleteResponse\n"; 
       AfxMessageBox(strMsg);
