OnSend Method (DicomNet)

Show in webframe
Example 







An error code.
The type of data that was sent.
The number of bytes of the data actually sent.
Notifies a connection that data was sent.
Syntax
protected virtual void OnSend( 
   DicomExceptionCode error,
   DicomPduType type,
   int length
)
'Declaration
 
Protected Overridable Sub OnSend( _
   ByVal error As DicomExceptionCode, _
   ByVal type As DicomPduType, _
   ByVal length As Integer _
) 
'Usage
 
Dim instance As DicomNet
Dim error As DicomExceptionCode
Dim type As DicomPduType
Dim length As Integer
 
instance.OnSend(error, type, length)
protected virtual void OnSend( 
   DicomExceptionCode error,
   DicomPduType type,
   int length
)

            

            
 function Leadtools.Dicom.DicomNet.OnSend( 
   error ,
   type ,
   length 
)
protected:
virtual void OnSend( 
   DicomExceptionCode error,
   DicomPduType type,
   int length
) 

Parameters

error
An error code.
type
The type of data that was sent.
length
The number of bytes of the data actually sent.
Remarks
When one of the DicomNet.SendXXX methods is called, the message is not sent immediately. It is placed in a network queue and sent later. When the data is actually sent, this method is called to let the calling AE know that the data has been sent.

To customize this method, you must derive a class from DicomNet and override this method.
