public virtual bool SerializePassword {get; set;}

'Declaration
 
Public Overridable Property SerializePassword As Boolean

'Usage
 
Dim instance As AnnObject
Dim value As Boolean
 
instance.SerializePassword = value
 
value = instance.SerializePassword

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

Property Value

true if this password is saved when this AnnObject is serialized; false otherwise.

Serialization is used throughout the annotation toolkit to save object states. For example, the annotation mode uses serialization to implement undo/redo buffers, copying/pasting objects to/from the clipboard as well as loading/saving objects to files or memory. Setting this property to false will not store the password field of a locked object when the object is serialized. This is not necessary in some situations such as implementing undo/redo buffers, but is very important to applications that do not want to save the password when objects are saved to disk files.
