'Declaration
 
Public Property AutoPan As Boolean

'Usage
 
Dim instance As CameraControl
Dim value As Boolean
 
instance.AutoPan = value
 
value = instance.AutoPan

public bool AutoPan {get; set;}

 get_AutoPan();
 set_AutoPan(value);

public:
property bool AutoPan {
   bool get();
   void set (    bool value);
}
