The Lock and Unlock Methods

Back

Lock Method

The Lock method prevents other users from modifying the variables in the Application object (used to ensure that only one client at a time can modify the Application variables).

Unlock Method

The Unlock method enables other users to modify the variables stored in the Application object (after it has been locked using the Lock method).

Syntax

Application.Lock
Application.Unlock

Examples

The example below uses the Lock method to prevent more than one user from accessing the variable visits at a time, and the Unlock method to unlock the locked object so that the next client can increment the variable visits:

<%
Application.Lock
Application("visits")=Application("visits")+1
Application.Unlock
%>
This page has been visited
<%=Application("visits")%> times!
