OnBeforeSendNActionResponse Method

Summary

Notifies an implementor before a DicomNet::SendNActionResponse is sent.

Syntax

C++/CLI

public virtual void OnBeforeSendNActionResponse( 
   DicomClient Client, 
   byte presentationID, 
   int messageID, 
   string affectedClass, 
   string instance, 
   DicomCommandStatusType status, 
   int action, 
   DicomDataSet dataset 
)

public:  
   virtual void OnBeforeSendNActionResponse( 
       DicomClient^ Client, 
      Byte presentationID, 
      Int32 messageID, 
      String^ affectedClass, 
      String^ instance, 
      DicomCommandStatusType^ status, 
      Int32 action, 
      DicomDataSet^ dataset 
   )

Parameters

Client

The client this notification applies to.

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.

status

The status of the original request.

action

An application-specific action to be performed on the specified Data Set.

dataset

A DicomDataSet object that contains the Data Set on which the specified action is to be performed.

Remarks

Override this method to view or change arguments before a DicomNet::SendNActionResponse is sent.

This can be used with DICOM listening services in the High-level PACS Framework. For example, you can create an assembly that contains the following code, and copy the assembly into the DICOM listening service 'AddIns' folder.

public class SendNotify : NotifySendMessageBase 
{ 
   public override void OnBeforeSendNActionResponse(DicomClient Client, byte presentationID, int messageID, string affectedClass, string instance, DicomCommandStatusType status, int action, DicomDataSet dataset) 
      { 
         // View or change parameters 
         base.OnBeforeSendNActionResponse(Client, presentationID, messageID, affectedClass, instance, status, action, dataset); 
      } 
}
