Sends an N-CREATE-REQ message to a peer member of a connection. This function is available in the Medical Suite Toolkit.
Parameter |
Description |
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. |
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. |
pszClass |
Class affected by the request. This will be an SOP Class or an SOP MetaClass. |
pszInstance |
The instance of the class. A server may, for example, have three instances of the Nuclear Medicine Class. This value identifies the data with a specific instance. |
pDS |
Data set with the information to use when creating. |
Returns
0 |
SUCCESS |
>0 |
An error occurred. Refer to Return Codes. |
Comments
Calling this function generates a call to LDicomNet::OnReceiveNCreateRequest on the SCP. The SCP should respond by calling LDicomNet::SendNCreateResponse which will generate a call to LDicomNet::OnReceiveNCreateResponse.
This function creates a new SOP Instance on the specified peer connection. The data set with the new information must be created and filled before calling this function.

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)
// identifieds 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
CString strMsg = "N-Create\n";
//Get the associate object
LDicomAssociate *pDicomAssociate = m_pDicomNet->GetAssociate();
//Choose an SOP Class to create--in this example, choose UID_SC_IMAGE_STORAGE
CString strClassUID = UID_SC_IMAGE_STORAGE;
//Choose an SOP Instance to create
CString strInstanceUID = "1.2.840.113619.2.30.1.1762288927.1489.906240296.255";
//Is class supported in the assocation?
L_UCHAR nPresentationID = pDicomAssociate->FindAbstract((L_CHAR *)(LPCTSTR)strClassUID);
//nPresentationID must be odd--0 indicates failure
if (nPresentationID==0)
{
CString strTmp;
strTmp.Format("Abstract Syntax[%s] Not Included in the Association", strClassUID);
strMsg = strMsg + strTmp;
}

//Here you would normally construct a data set containing the attributes, values for the new SOP instance
//For this sample, pick a dicom file to send as the data set
