ASP Lock and UnlockMethods
Complete Application Object Reference Manual
Lock Method
The Lock method prevents other users from modifying variables in the Application object (used to ensure that only one user can modify Application variables at a time).
Unlock Method
The Unlock method allows other users to modify variables stored in the Application object (after it has been locked using the Lock method).
Syntax
Application.Lock
Application.Unlock
Application.Unlock
Example
The following example uses the Lock method to prevent more than one user from accessing the variable visits at the same time, and uses 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!
Application.Lock
Application("visits")=Application("visits")+1
Application.Unlock
%>
This page has been visited
<%=Application("visits")%> times!
