CloseForced Method (DicomNet)

Closes an ISCL connection.

Syntax

Visual Basic
C#
WinRT C#
Objective-C
Java
WinRT JavaScript
C++

public void CloseForced( 
   bool forced
)

'Declaration
 
Public Sub CloseForced( _
   ByVal forced As Boolean _
)

'Usage
 
Dim instance As DicomNet
Dim forced As Boolean
 
instance.CloseForced(forced)

public void CloseForced( 
   bool forced
)

ObjectiveC Syntax

 function Leadtools.Dicom.DicomNet.CloseForced( 
   forced 
)

public:
void CloseForced( 
   bool forced
)

Parameters

forced: true to kill the connection (force the disconnection); false to request the disconnection (the disconnection can be refused by a peer).

Remarks

When forced is set to true, the connection is closed immediately. Therefore, it is best to determine if the ISCL message queue is empty before calling this method. To determine whether the ISCL queue is empty, use the IsIsclQueueEmpty method.

Please note that CloseForced(false) is queued in the ISCL message queue (it will be processed later). CloseForced(true) is immediate, however.
