'Declaration
 
Public Overridable Sub Lock( _
   ByVal password As String _
)

'Usage
 
Dim instance As AnnObject
Dim password As String
 
instance.Lock(password)

public virtual void Lock( 
   string password
)

 function Leadtools.Windows.Annotations.AnnObject.Lock( 
   password 
)

public:
virtual void Lock( 
   String^ password
)

Parameters

password: String containing the password used to lock the annotation object.

Only unlocked objects can be locked. If an object is already locked, it will stay locked with its original password. You must pass the same password to Unlock to unlock this AnnObject.

If this method succeeds, password will be stored inside the object and can be retrieved with the Password property.

An object must be unlocked in order to change that object in automated mode.
