[VB.NET]
Event OnBeforeOpenSubsystem As TSSHBeforeOpenSubsystemEvent
Delegate Sub TSSHBeforeOpenSubsystemEvent(ByVal Sender As Object, ByVal Subsystem As String, ByVal Connection As TElSSHTunnelConnection, ByRef Accept As Boolean)

[Pascal]
property OnBeforeOpenSubsystem: TSSHBeforeOpenSubsystemEvent;
TSSHBeforeOpenSubsystemEvent = procedure(Sender: TObject; const Subsystem: string; Connection: TElSSHTunnelConnection; var Accept : boolean) of object;

[C++]
    void get_OnBeforeOpenSubsystem(TSSHBeforeOpenSubsystemEvent &pMethodOutResult, void * &pDataOutResult);
    void set_OnBeforeOpenSubsystem(TSSHBeforeOpenSubsystemEvent pMethodValue, void * pDataValue);
    typedef void (SB_CALLBACK *TSSHBeforeOpenSubsystemEvent)(void * _ObjectData, TObjectHandle Sender, const char * pcSubsystem, int32_t szSubsystem, TElSSHTunnelConnectionHandle Connection, int8_t &Accept);

[PHP]
    TSSHBeforeOpenSubsystemEvent|callable|NULL get_OnBeforeOpenSubsystem()
    void set_OnBeforeOpenSubsystem(TSSHBeforeOpenSubsystemEvent|callable|NULL $Value)
    callable TSSHBeforeOpenSubsystemEvent(TObject $Sender, string $Subsystem, TElSSHTunnelConnection $Connection, bool &$Accept)

[Java]
    TSSHBeforeOpenSubsystemEvent getOnBeforeOpenSubsystem();
    void setOnBeforeOpenSubsystem(TSSHBeforeOpenSubsystemEvent Value);
    TSSHBeforeOpenSubsystemEvent.Callback OnBeforeOpenSubsystem = new TSSHBeforeOpenSubsystemEvent.Callback() {
        public void TSSHBeforeOpenSubsystemEventCallback(TObject Sender, String Subsystem, TElSSHTunnelConnection Connection, TSBBoolean Accept) {
            //...
        }
    }
