Examples
The following code example uses the Unprotect method to remove protection from the document. The example assumes that the password variable securelyStoredPassword was obtained from user input. To use this example, run it from the ThisDocument class in a document-level project.
Private Sub DocumentUnprotect(ByRef securelyStoredPassword As Object)
If Me.ProtectionType <> Word.WdProtectionType.wdNoProtection Then
Me.Unprotect(securelyStoredPassword)
End If
End Sub
private void DocumentUnprotect(ref object securelyStoredPassword)
{
if (this.ProtectionType != Word.WdProtectionType.wdNoProtection)
{
this.Unprotect(ref securelyStoredPassword);
}
