Syntax

C++

public virtual void OnBeforeSendNCreateRequest( 
   DicomClient Client, 
   byte presentationID, 
   int messageID, 
   string affectedClass, 
   string instance, 
   DicomDataSet dataSet 
)

Public Overridable Sub OnBeforeSendNCreateRequest( 
   ByVal Client As DicomClient, 
   ByVal presentationID As Byte, 
   ByVal messageID As Integer, 
   ByVal affectedClass As String, 
   ByVal instance As String, 
   ByVal dataSet As DicomDataSet 
)

public:  
   virtual void OnBeforeSendNCreateRequest( 
       DicomClient^ Client, 
      Byte presentationID, 
      Int32 messageID, 
      String^ affectedClass, 
      String^ instance, 
      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.

dataSet

A DicomDataSet object that contains the Data Set with the information to use when creating.

Remarks

Override this method to view or change arguments before a DicomNet::SendNCreateRequest 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 OnBeforeSendNCreateRequest(DicomClient Client, byte presentationID, int messageID, string affectedClass, string instance, DicomDataSet dataSet) 
      { 
         // View or change parameters 
         base.OnBeforeSendNCreateRequest(Client, presentationID, messageID, affectedClass, instance, dataSet); 
      } 
}
