HasOpenPassword Property

Gets the value indicating whether the Workbook has an open password and will therefore be encrypted on subsequent saves.

Syntax

Visual Basic

'Declaration
 
Public ReadOnly Property HasOpenPassword As Boolean

C#

public bool HasOpenPassword {get;}

Remarks

Workbook instances loaded from encrypted files or streams will cache the password used to decrypt the document and reuse it on subsequent saves. Therefore, HasOpenPassword will initially be true for Workbooks loaded from encrypted files or streams and false for all other Workbooks.

The open password can be cleared or reset by using SetOpenPassword.
