SendNReportRequest Method

Summary

Sends an N-EVENT-REPORT-REQ message to a peer member of a connection.

Syntax
C#
VB
C++
public void SendNReportRequest( 
   byte presentationID, 
   int messageID, 
   string affectedClass, 
   string instance, 
   int dicomEvent, 
   DicomDataSet dataSet 
) 
Public Sub SendNReportRequest( _ 
   ByVal presentationID As Byte, _ 
   ByVal messageID As Integer, _ 
   ByVal affectedClass As String, _ 
   ByVal instance As String, _ 
   ByVal dicomEvent As Integer, _ 
   ByVal dataSet As DicomDataSet _ 
)  
public: 
void SendNReportRequest(  
   byte presentationID, 
   int messageID, 
   String^ affectedClass, 
   String^ instance, 
   int dicomEvent, 
   DicomDataSet^ dataSet 
)

Parameters

presentationID
The Presentation Context ID. The ID provides information about both the class type of the data and the Transfer Syntax to use when transferring the data.

messageID
The 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.

affectedClass
The class affected by the request. This will be a SOP Class or a Meta SOP Class.

instance
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.

dicomEvent
An application-specific event for which a report is to be generated.

dataSet
A DicomDataSet object that contains an application-specific Data Set which contains information related to the operation.

Remarks

Calling this method generates a call to OnReceiveNReportRequest on the SCP. The SCP should respond by calling SendNReportResponse which will generate a call to OnReceiveNReportResponse. A report is generated to let all peers attached to a server know of some event that has occurred. This event may be the addition of a new patient, the deletion of a patient, the addition of a new study, etc. The dicomEvent value, which designates the event that occurred, is determined by the server. To find out the values used, you must contact the organization that created the server. When creating a server, the values and their corresponding meanings are determined by those creating the server.

Example

This is a comprehensive sample that shows how to process a DICOM N-Report operation on both the SCP (server) and the SCU (client) sides.
