'Usage Dim instance As AnnAutomation instance.Lock()
public: virtual void Lock();
Use the CanLock property to determine whether you can currently call this method.
This method opens the AnnAutomationManager.PasswordDialogType window and uses the value entered in this dialog as the password to AnnObject.Lock.
If the AnnAutomationManager.PasswordDialogType value is null (Nothing in Visual Basic), this method will not do anything.
