ASP Lock and Unlock Methods
Definition and Usage
Lock Method
The Lock method prevents other users from modifying the variables in the Application object (to ensure that only one user can modify the Application variables at a time).
Unlock Method
The Unlock method allows other users to modify the variables stored in the Application object (after they have been locked using the Lock method).
Syntax
Application.Lock Application.Unlock
Example
The following examples use the Lock method to prevent more than one user from accessing the variable visits at the same time, and use the Unlock method to unlock the locked object, so that the next user can increase the value of the variable visits:
<%
Application.Lock
Application("visits")=Application("visits")+1
Application.Unlock
%>
This page has been visited
<%=Application("visits")%> times!
