Name

Lock — Application.Lock

Synopsis

The Lock method locks the Application object, preventing any other client from altering any variables' values in the Contents collection (not just those variables you alter before calling the Unlock method). The corresponding Unlock method is used to release the Application object so other clients can again alter the Contents collection variable values. If you fail to use the Unlock method, IIS will unlock the variable automatically at the end of the current Active Server Pages script or upon script timeout,[3] whichever occurs first.

Parameters

None

Example

<%
' This script exists on the second page of a 
' multipage ASP application, so that users may
' or may not visit it. The example shows how you could
' see how many visitors the page has had.
' Assume that TotalNumPage2 starts at 0.

' Lock the Application object.
Application.Lock

intNumVisits = Application.Contents("TotalNumPage2")
intNumVisits = intNumVisits + 1
Application.Contents("TotalNumPage2") = intNumVisits

' Explicitly unlock the Application object.
Application.Unlock

' NOTE: Using the PageCnt.DLL would be a more
' efficient manner of doing this.
