OnBeforeSendCCancelRequest Method


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

public virtual void OnBeforeSendCCancelRequest( 
   DicomClient Client, 
   byte presentationID, 
   int messageID 



The client this notification applies to.


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.


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.


Override this method to view or change arguments before a DicomNet::SendCCancelRequest 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 OnBeforeSendCCancelRequest(DicomClient Client, byte presentationID, int messageID) 
         // View or change parameters 
         base.OnBeforeSendCCancelRequest(Client, presentationID, messageID);
